Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high pressure for treating the surface of a structure, which is capable of efficiently and safely ejecting high-pressure water along the inner and outer walls of the structure, the ceiling, etc. to remove and clean the surface layer. The present invention relates to a water jet operating method.

[0002]

2. Description of the Related Art Conventionally, when a new exterior coating is applied to the surface of a concrete structure, such as an outer wall of a high-rise house, a commercial building, or a factory, the old exterior is mainly peeled by hand, and the surface after the peeling is removed. Is further cleaned and the surface is refurbished with new exterior materials. In this exterior renovation work, the exterior material that adheres directly is peeled off using a grinder or chipper to remove the old exterior material, and this peeling and removing work requires the most labor, and the removal work is also required. If not done carefully, many obstacles will occur when applying a new exterior.

Since a lot of manpower is required for such remodeling work, recently, instead of the direct peeling work by manpower, an old exterior material such as resin which is attached to the surface of the structure by using high pressure water. A method of peeling a coating film with high energy due to collision of high-pressure water is being adopted.

[0004]

However, the above-mentioned work of peeling the exterior material adhering to the surface of the structure by using the high-pressure water has been conventionally performed in order to obtain a peeling effect.
The operator uses the high-pressure water having a pressure of about cm ² to spray an injection pipe equipped with a small-diameter injection nozzle onto the target wall surface by hand to spray the high-pressure water. Naturally, the worker's own body supports the reaction force when the high-pressure water is ejected toward the surface to be treated. For this reason, if this work is continued for a long time, the physical strength is inevitably deteriorated and the degree of fatigue is increased, which is not preferable in terms of occupational safety and health.

In particular, in order to improve the efficiency of the peeling work and increase the processing area in a short time, the workability of the above-mentioned high-pressure water is not good, so it is necessary to further increase the pressure of the high-pressure water used. . Therefore, the present inventor sets the pressure of the high-pressure water to 30
It was confirmed that the processing capacity and the workability were increased by increasing it to 0 to 500 kgf / cm ² . As described above, it was confirmed that if the pressure of the injected water is made higher, the breaking energy due to the collision of the high-pressure water becomes large as expected, and that the peeling work can be performed much more efficiently than in the past. When the pressure of the high-pressure water to be jetted is increased and the diameter of the jet nozzle is larger than the conventional one, for example, 1.5 mm, the discharge water amount also increases in proportion to the pressure of the supplied pressure water (for example, 5
(60 liters / min with pressure water of 00 kgf / cm ² ), and the breaking energy increases with the increase, so it is possible to easily peel off even stucco (stucco) etc., which was conventionally difficult in the peeling work of the surface layer of the structure. It became so.
However, in the above example, a reaction force of 33.6 kgf / cm ² is generated as an injection reaction force of the injection water for an operator who holds the injection pipe equipped with the injection nozzle of the high-pressure water, and a large load acts. Therefore, the work must be interrupted in an extremely short time, and the actual work time of the worker must be shortened in inverse proportion to the work efficiency.

The present invention solves the above-mentioned problems, makes it possible to effectively use the energy of high-pressure water to improve work efficiency, and safely perform work such as peeling without burdening the operator. It is an object of the present invention to provide a method of operating a jet part of high-pressure water for treating the surface of a possible construct.

[0007]

In order to achieve such an object, the present invention firstly provides at least one guide means arranged along a work surface of a structure to be processed, and the guide means is provided in the guide means. A traveling body is movably mounted along the traveling body, and a high pressure water jet nozzle connected to a high pressure water supply source by a holding member attached to the traveling body directs high pressure water toward the work surface to be treated. The high-pressure water jetted from the high-pressure water jet nozzle is used to perform the work to be processed by moving the traveling body directly or remotely.

Secondly, the present invention secondly provides a plurality of traverse guide means parallel to each other at required intervals as guide means for a traveling body provided with a holding member for a high-pressure water jet nozzle along a work surface of a structure to be treated. Along the way, the longitudinal guide means is installed between the traveling bodies mounted on the transverse guide means, and the main traveling body is movably mounted on the longitudinal guide means and attached to the main traveling body. A high-pressure water injection nozzle connected to a high-pressure water supply source by a holding member is supported so as to inject high-pressure water toward the work surface to be processed, and the vertical direction is provided by direct or remote operation along the traverse guide means. The row guide means is made to traverse and the main traveling body is made to traverse longitudinally so that the high pressure water jetted from the high pressure water jet nozzle supported by the main traveling body is used to perform the work to be treated. .

[0009]

In the method for operating the high-pressure water jetting portion for treating the surface of the first structure of the present invention thus configured, the guide member of the traveling body is first moved to a desired section with respect to the target work surface. The high-pressure water injection nozzle is supported by the holding member attached to the traveling body that is movably supported by this guide member, and this high-pressure water injection nozzle is connected to the high-pressure water supply source with a hose to the work surface to be treated. The operator directly or remotely operates the high-pressure water jet nozzle to inject high-pressure water onto the work surface to be processed, and perform work such as peeling and cleaning depending on the condition of the work surface to be processed. With this configuration, if the high-pressure water jet nozzle is held by the holding member of the traveling body and is moved along the guide member while jetting high-pressure water according to the work situation, the exterior material of the work surface to be processed is sequentially obtained. The processes such as peeling and cleaning can be performed freely and reliably without burdening the operator.

Further, in the method of operating the high-pressure water jetting section for treating the surface of the second structure, a plurality of traverse guide members are attached in parallel to the target work surface at required intervals in required sections. Then, the vertical guide means is installed between the traveling bodies mounted on these transverse guide members, the main traveling body is movably mounted on the longitudinal guide means, and the main traveling body is attached to the main traveling body. The holding member supports the high-pressure water jet nozzle connected to the high-pressure water supply source and directs it toward the work surface to be processed. Then, by injecting high-pressure water toward the work surface to be processed while the operator traverses and vertically runs the high-pressure water jet nozzle by direct operation or remote operation, the exterior material of the work surface in a wide range can be obtained. This makes it possible to perform processes such as peeling and cleaning freely and reliably and efficiently without burdening the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method for operating a high-pressure water jetting section for treating the surface of a structure of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view showing an example of an apparatus for carrying out a method for operating a high-pressure water jet section for treating the surface of a first structure of the present invention, and the present invention is shown in this figure. It is carried out using a device as described above. First, the apparatus for carrying out the method of operating the high-pressure water jetting part for treating the surface of the first construct of the present invention is supported by the support legs 2 whose bases are fixed at predetermined intervals, for example, on the wall surface of the construct for treating the surface. Guide rail 1, a traveling body 4 which is guided by the guide rail 1 and movably mounted, a holding member 6 which is attached to the traveling body 4 and supports a high-pressure water jet nozzle 5, and high-pressure water. It is composed of a jet nozzle 5 and a high-pressure water supply device (not shown).

The guide rails 1 are disposed at appropriate intervals on the work surface to be treated so as to withstand the jet reaction force during operation of the high-pressure water jet nozzle 5 supported by the traveling body 4 and a holding member 6 attached to the traveling body 4. A plurality of support legs 2 attached to A support the rear surface of the support legs 2. The guide rail 1 is preferably lightweight and easy to handle, and the cross-sectional shape is not particularly limited. A rack 3 is provided along the front side of the guide rail 1, preferably. The rack 3 may be provided with a cutting tooth or a roller chain with an attachment, and is preferably water resistant.

The traveling body 4 is mounted on the guide rail 1 so that it can travel freely, and three or more (eight in a specific example) guide rollers are in contact with the upper and lower surfaces of the guide rail 1.
It is composed of a support plate 42 supported by 41, and traveling drive means 43 for traveling the support plate 42 along the guide rail 1. The support plate 42 is formed of a rectangular plate material having a required size. The traveling drive means 43 has a pinion 43b attached to an inner end portion of a shaft 43a rotatably supported at a proper position of its support plate 42, and the pinion 43b is meshed with the rack 3 attached to the guide rail 1. For example, a handle 43c is attached to the outer end of the shaft 43a, and the pinion 43b is rotated by the handle 43c so that the shaft 43a travels. Regarding the drive of the traveling drive means 43, for example, a motor may be attached to the support plate 42 and the motor may be operated by remote control so that the vehicle can travel.

The high-pressure water injection nozzle 5 has, for example, a diameter of 1 to 1.5 mm, and high-pressure water is connected to a high-pressure water supply device (not shown) by a hose 7 to 300 to 500 Kgf /
A pressure of cm ² is used. The holding member 6 for supporting the high-pressure water jet nozzle 5 on the traveling body 4 is, for example, a member of a proper length whose base end is pivotally supported by a shaft at an appropriate position on the front surface of the support plate 42 of the traveling body 4. The high-pressure water jet nozzle 5 is attached to the tip of the holding member 6 so that high-pressure water can be jetted toward the work surface to be processed. At the mounting portion of the high-pressure water jet nozzle 5 at the tip of the holding member 6, it is desirable that the facing distance between the high-pressure water jet nozzle 5 and the work surface A to be processed can be adjusted. It is desirable that the holding member 6 be configured so that it can be fixed and held at a required position by rotating around a shaft so that high-pressure water can be sprayed at a position where it cannot be sprayed onto the guide rail 1.

In order to carry out the present invention, the high-pressure water jet device having the above-mentioned structure is used. In carrying out this, first, the guide rail 1 is attached to the work surface A to be processed (for example, the outer wall surface) in a required length. The guide rail 1 is constructed by implanting the attachment anchor bolts 2a of the support legs 2 at a predetermined interval according to working conditions and the like by a well-known means, and supporting them by the support legs 2 attached by the anchor bolts 2a. Next, the traveling body 4 is attached to the guide rail 1
The high-pressure water jet nozzle 5 is mounted toward the work surface A to be treated at the tip of the holding member 6 attached to and attached to, and is connected to the high-pressure water supply device by the hose 7 so that the water can be jetted.

To start the work, the holding member 6 is rotated around the shaft 43a in accordance with the work position of the high-pressure water jet nozzle 5 with respect to the work surface A to be processed, and is arranged and fixed above or below the guide rail 1. To do. After that, the worker rotates the handle 43c of the traveling drive means 43 while supplying and jetting the required high-pressure water to the high-pressure water jet nozzle 5, and the traveling body 4 is jetted with the high-pressure water to treat the work surface A to be treated. Work at a speed that suits the situation. In this state, since the preset distance between the high-pressure water jet nozzle 5 and the work surface A to be processed is always kept constant and traversed, the high-pressure water jet nozzle 5 is attached so that the facing distance thereof becomes the optimum condition. If the above is set, the worker can achieve the purpose only by moving the traveling body 4 while adjusting the traveling speed according to the working situation as described above.

In this way, if the laying range of the guide rail 1 is moved by one stroke, thereafter, the position of the high-pressure water jet nozzle 5 is shifted and reciprocally moved in the above-described manner, so that the holding member along the guide rail 1 is moved. It is possible to perform processing work in the range of 6 which can be displaced. During this time, the operator only has to operate the device and can work under a constant condition without being burdened by the high-pressure water spray on the body as in the conventional case, so that the efficiency can be improved.

When the processing of the workable range is completed as described above, the traveling body 4, the guide rail 1 and the supporting legs 2 thereof are removed and moved to the next work position, and the above-mentioned operation is repeated to perform the required work. Can handle faces. Since the portion corresponding to the mounting portion of the guide rail 1 remains as a "dead" in a small area, it may be processed by a conventional manual high-pressure water jetting operation when the guide rail 1 is transferred. .

A vertical drive means 38 is provided which can be moved up and down by rotating a handle 38f attached to the upper gear support shaft 38e.

As shown in FIG. 2, the main traveling body 35 thus constructed is provided with a holding member 40 protruding laterally, and the holding member 40 has an arm whose base is fixed to the supporting plate 35. A sliding support mechanism 46 mounted in a direction orthogonal to the protruding direction is provided above the tip of 45, and a high-pressure water jet nozzle 50 changes the jetting direction to a nozzle support piece 48 attached via this sliding support mechanism 46. Is attached to the state.
The slide support mechanism 46 is provided with a mechanism capable of moving forward and backward with respect to the work surface A to be processed, and the nozzle support piece 48 is attached to a movable piece 46 'of the slide support mechanism 46 by a bracket 47 which is attached to the work piece to be processed.

In the figure, reference numeral 46 "is a screw for moving the movable piece 46 'forward and backward, 46a is a sliding support piece for the movable piece 46', and 49 is a lever for vertically rotating the jet nozzle. The high pressure water supply system is the same as that of the above-mentioned embodiment.

In the practice of the present invention by the high-pressure water jetting device constructed as described above, first, as in the case of the above-described embodiment, the main guide rail 10 for traversing the work surface A (for example, the outer wall surface) to be processed at a required distance is provided. Attach it in parallel with the auxiliary guide rail 10A. Next, these main and auxiliary guide rails 10, 10A
In response to the above, the traveling traveling body 20 and the auxiliary traveling body 20a for traverse
Is installed and the vertical guide rail 30 is installed,
The main traveling body 35 is arranged so as to be vertically and horizontally movable. A holding member 40 is attached to the main traveling body 35 in advance, and a nozzle support piece 48 of the holding member 40 has a high-pressure water jet nozzle.
The injection direction 50 is attached so that the injection direction faces the work surface A to be processed, and the high-pressure water injection nozzle 50 is connected to a high-pressure water supply device (not shown) by the hose 7 so that the injection can be performed.

To start the work, the high-pressure water jet nozzle 50 supported by the nozzle support piece 48 of the holding member 40 is adjusted by the bracket 47 for adjusting the jet distance and the jet direction with respect to the work surface A to be treated. On the upper side, the lever 49 for vertically rotating the injection nozzle is rotated around the support shaft 38a, and a sliding support mechanism is also provided.
The movable part 46 "of 46 is moved back and forth to set the optimum state. After that, the high-pressure water jet nozzle 50 is supplied to the high-pressure water jet nozzle 50 and jetted according to the working position (described later). While operating, the operator rotates the handle 23c of the traveling drive means 23 for traverse to move the drive traveling body 20 along the main guide rail 10 for traverse so that high-pressure water is jetted onto the work surface A to be treated. Therefore, when the desired processing is performed by traversing the main and auxiliary guide rails 10 and 10A for traverse in the laying section, the vertical guide rail 30 attached to the vertical guide rail 30 is attached at the end position. By rotating the upper gear 38a by operating the handle 38f of the row drive means 38, the endless toothed belt 38c is driven to drive the main traveling body.

The movable range of A is sequentially moved in a reciprocating manner by shifting the position of the high-pressure water jet nozzle 50 in the required pitch in the vertical direction in the above-described manner, so that high-pressure water is jetted onto a wide range of work surface A to be treated and attached exterior material. Work such as peeling and cleaning of the surface after peeling can be performed quickly without imposing a burden on the operator himself. With respect to the movement of the main traveling body 35, the work can be performed by traveling at a speed corresponding to the processing situation on the work surface A to be processed, as in the above-described embodiment.

Thus, both main and auxiliary guide rails for traverse
When the work within the area where 10 and 10A are laid is completed, both the main and auxiliary guide rails 10 and 10A for these traverses and the driving vehicle
20. The auxiliary traveling body 20a (at the same time, the longitudinal guide rail 30 and the main traveling body 35 mounted on the longitudinal guide rail 30) are removed and moved to the adjacent portion, and then the work surface A to be treated is processed in the same manner as described above.
Repeat the operation for processing. It should be noted that the above-described procedure for moving the main traveling body 35 is performed by traversing and sequentially shifting each post-processing range in the vertical direction, but it is not limited to this procedure and the main traveling in the vertical direction is performed. The body 35 may be sequentially moved laterally by the processing width while moving. In this case, the stopping means 27 attached to the drive traveling body 20 is used, and the locking piece 27 of the stopping means 27 is provided while the traverse is stopped.
If the movement of the drive traveling body 20 is stopped by b, the processing work can be performed without shifting the movement of the vertically traveling main traveling body 35. In some cases, it is also possible to operate while moving vertically and horizontally at the same time. In any case, if the relationship between the high-pressure water jet nozzle 50 and the work surface A to be processed is set in advance, the state can be maintained thereafter and the high-pressure water jet can be held in a constant state. Since it suffices to carry out the operation of moving the main traveling body 35 (injection nozzle), the work can be performed efficiently, and further, the work can be performed safely without physical burden. Also, both main and auxiliary guide rails 10 and 10 for traverse
As for the "damage" that occurs after the removal of A, since it is a small space as in the above-mentioned embodiment, it may be manually processed.

Further, according to the gist of the present invention, the guide rails for traverse are arranged in three or more rows, and a plurality of longitudinal guide rails are installed so as to traverse between the guide rails for traverse. The main traveling body is mounted on each of the longitudinal guide rails in the above-mentioned manner, and the high-pressure water jet nozzles are arranged in the respective manners so that the main traveling body and the traveling traveling body for traverse can be driven by an electric motor. By performing remote control by the worker, it becomes possible to perform a wide range of processing work.

According to the present invention, since the surface of a wide range of structures can be treated with high-pressure water in this way, it is suitable for removing the exterior material of an aged concrete structure, for example. At the same time as doing, cracks and the like can be easily found without damaging the skeleton, and it is possible to easily respond afterwards. Then, the present invention can be applied not only to the outer wall but also to the ceiling, the floor surface, and the like as needed.

The apparatus for carrying out the method for operating the high-pressure water jetting section for treating the surface of the structure of the present invention is not limited to the one described above, and may have any structure capable of achieving the purpose. For example, a structure other than the above-mentioned embodiment can be adopted.

The guide rail 1 for traverse in this embodiment is the guide member of the present invention, both the main and auxiliary guide rails 10 and 10A for traverse are guide members for traverse, and the traveling body 4 is a traveling body. The drive traveling body 20 and the auxiliary traveling body 20a correspond to the traveling body of the transverse guide means, and the longitudinal guide rail 30 corresponds to the longitudinal guide means.

[0034]

As described above, according to the present invention, the high-pressure water injection nozzle for injecting high-pressure water to face the work surface to be processed is provided along the guide member laid along the work surface to be processed. Then, it is held in a predetermined state, and the work is facilitated by injecting high-pressure water toward the work surface to be processed while moving it at a required speed. Moreover, since the working reaction force due to the high-pressure jet water does not act on the worker, and the processing work can be continuously performed for a long time without difficulty, for example, the peeling work of the exterior material, which has been difficult in the past, can be done easily and easily. As a result, the work efficiency can be significantly improved. Further, since the worker can easily deal with the high-pressure water jet nozzle according to the situation, it is possible to work safely without danger. If a plurality of transverse guide members are arranged so that the high-pressure water jet nozzle can be moved vertically and horizontally, a wide range of work can be easily and efficiently carried out. The equipment cost can be reduced by relocating the guide member and repeatedly using it.
