Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining device which is capable of automatically lining bricks on the walls of buildings by the arch construction method or on the ceilings and inner walls of various structures.

[0002]

2. Description of the Related Art In various buildings and structures, the work of lining bricks on a wall surface forming a closed internal space is performed by a method of sequentially stacking bricks along the walls.

Further, even when the ceiling surface is arched or the vertical cross-section of the internal space is circular, the same method is used, but bricks are laid down in the process of installing bricks on the ceiling part. Expected to fall. Therefore, in the past, bricks were stacked in layers on the rising wall part of the internal space, and for the construction of the arch part, a fixed frame that sandwiches the brick with the wall surface was prepared, and this fixed frame The work of arranging bricks around is done. Then, after arranging the bricks around the wall surface, the fixed frame is displaced from the existing brick row to build a new brick row.

In addition to such construction, in the case of a rotary kiln, for example, there is also a method in which the rotation is used to make the portion where the brick is stretched always face downward and the brick is pressed by a screw jack to work.

[0005]

However, in the case where the fixed frame is used, the worker manually stacks the bricks one by one, so that the working efficiency is limited and the burden on the worker is considerable. Requires large and highly skilled skills. Further, when the brick is installed on the ceiling surface, there is a high possibility that the brick will be dropped, and there is a big problem of safety.

On the other hand, in the construction method using the screw jack, the structure is limited to the one that rotates, so that it is impossible to deal with it in various directions. I can't expect any improvement.

As described above, in the past, the method of stacking bricks was mainly used only by hand, so that there was a great obstacle in terms of work efficiency, leading to a longer construction time and higher costs.

The problem to be solved by the present invention is to provide an inner lining device which can be constructed efficiently by eliminating the work burden of lining bricks on the inner wall of a structure having an arch or a circular cross section.

[0009]

SUMMARY OF THE INVENTION A brick lining device of the present invention is a crimp for crimping a brick that is generally positioned to be lined to the inner wall of a structure and several bricks that have been lined in advance toward the inner wall. A device is provided, and the crimping device is movable in the lining direction from the lower layer to the upper layer of the brick.

Further, there are provided a feeder for conveying the brick toward the inner wall of the structure, and a crimping device for crimping the brick delivered from the feeder and several bricks lined in advance toward the inner wall. The feeding device and the crimping device are movable in the lining direction from the lower layer to the upper layer of the brick, and the feeding device is arranged in advance in the lining direction, and the crimping device is arranged with respect to the feeding device. It is also possible to adopt a configuration in which they are arranged subsequently.

The crimping device including the crimping device or the feeding device may be rotatably connected to each other around a support shaft arranged on the traveling carriage.

It is also possible to arrange a gondola for an operator which can be driven independently of the movement of the feeding device and the crimping device around the support shaft.

[0013]

[Function] The bricks are transferred one by one toward the inner wall of the structure and set so as to be placed on the upper layer of the existing brick, and after this setting, the lining direction is set to the upper layer side so that the crimping device follows the feeding device. If the bricks are moved toward each other, the set bricks are restrained and held to the inner wall side by the crimping device.

When the feeder is provided, the bricks are conveyed from the feeder toward the inner wall of the structure one by one,
The brick is set so that it can be paid out first and placed on top of the existing brick located on the inner wall side. Then, after this setting, the crimping device moves so that the lining direction is directed toward the upper layer side so as to follow the rear of the feeding device, so that the brick fed from the feeding device is restrained and held to the inner wall side by the crimping device.

When the bricks are lined while being laminated in this way, even if the inner walls have an arcuate ceiling surface, the laminated bricks may be constrained by their respective weights. This makes it possible to mechanically process the brick lining.

Further, by arranging the feeding device and the crimping device rotatably around the support shaft of the traveling carriage, if the traveling carriage is moved in the axial direction of the structure, the structure will be moved. It is also possible to line bricks in the longitudinal direction.

Furthermore, by providing a gondola for workers, it is possible to manually install the brick into a portion that cannot be mechanically processed.

It is assumed that the spring 4h-2 is interposed between the and. By providing such a spring 4h-2, the belt 4f can be swiftly run even against unevenness of the brick. In addition, as described above, the crimping device 4
Is integrally connected to the feeding device 3 by the bracket 4a-2, and holds the brick between the tip side of the belt 4f and the feeding device 3 on the iron skin 50 side. Therefore, in the illustrated example, two auxiliary pressing rollers 4i are provided. Set up.

The gondola 5 has a first arm 5a rotatably connected to the support shaft 2 and a second arm 5b connected to the tip thereof.
And is connected to the tip of the second arm 5b. A gear 5d that is rotationally driven by a motor 5c is provided at the joints of the first and second arms 5a and 5b, and this gear 5d meshes with a fixed gear 2f provided around the support shaft 2. A holding cylinder 5e is installed between the support shaft 2 and the gondola 5, and the extension and contraction of the holding cylinder 5e causes the gondola 5 to move.

Further, in order that the gondola 5 always maintains a correct vertical posture with respect to the direction of gravity, chains 5g and 5h are hung on a sprocket provided coaxially with the support shaft 2, the output shaft of the motor 5c and the gondola support shaft 5f, and a parallel movement mechanism. Shall be configured. The gondola 5 also has a lock structure using a ratchet mechanism as in the crimping device 4 to ensure work safety.

Here, the feeding device 3 and the crimping device 4 run on the inner wall of the brick 51 on which the belt 4f is loaded by the operation of the electric motor 4g of the crimping device 4, and the positions thereof are gradually changed according to the position where the bricks are loaded. Go. Further, the gondola 5 is provided with an operating portion itself, and an operator riding on the operating portion can operate it to operate completely independently of the feeding device 3 and the crimping device 4. Then, as described above, the feeding device 3 and the crimping device 4 are also provided with the right arrangement so as to be symmetrical with the left arrangement shown in FIG. Control to move from the ceiling to the ceiling at the same speed. At the time of this control, one of the left side and the right side of the pair of the feeding device 3 and the crimping device 4 is prevented from moving in advance toward the ceiling side beyond the predetermined limit, and the reaction force due to the crimping to the brick is prevented. You need to keep your balance.

FIG. 12 is a schematic view showing the principle of a device for limiting the left-right asymmetric operation of the crimping device 4 within a predetermined limit, and the behavior of the crimping device 4 will be described.

The link rods 4j and 4k are connected to the left and right arms 4a of the crimping device 4, and the tip ends of these link rods 4j and 4k are joined by pins to connect the pin portions to the block 4m. The block 4m has a pin inserted into the slit 4n, and has a mechanism capable of swinging and tilting right and left around the support shaft 2 by the operation of the two arms 4a. And block 4m
A pair of limit switches 4p and 4q are arranged at positions sandwiching.

By providing the block 4m and the limit switches 4p and 4q as described above, when the crimping device 4 on the left side comes up first as shown in FIG. 12, the block 4m is placed on the left side by the link rods 4j and 4k. Hit the limit switch 4p of. Utilizing this,
The ascending of the left crimping device 4 is temporarily stopped, and the crimping device 4 on the right side is operated while maintaining a bilaterally symmetrical relationship. It is to be noted that the advance operation of the crimping device 4 arranged on the right side can be similarly limited to maintain the symmetrical relationship with the crimping device 4 arranged on the left side.

In the above construction, the brick 51 is laid in advance only on the bottom side inside the iron skin 50 over the entire length of the kiln so that the traveling carriage 1 can travel on these 51 bricks. . After this preparatory work, the traveling carriage 1 is carried in as shown in FIGS. 1 and 2, and is set so that the axis of the support shaft 2 coincides with the core of the iron skin 50.

As a method of setting this position, as shown in the schematic view of FIG. 13, a sensor 8 utilizing ultrasonic waves, infrared rays, visible rays or lasers is provided at the tip of the spindle 2.
The posture may be adjusted using the transmission and reception of ultrasonic waves, infrared rays, visible rays, or lasers between the target 8a and the inner wall surface of the iron skin 50, which are pre-arranged coaxially outside the iron skin 50. . The target 8a may be installed inside the iron skin 50.

For stacking the bricks 50, the traveling carriage 1 is moved in the axial direction of the steel shell 50, positioned in the axial direction with respect to the array of bricks in the preceding row, and the tip of the feeding device 3 is in the front row. Set to accommodate bricks.

After the position of the traveling carriage 1 is set, the bricks are fed one by one from the feed-out conveyor 6 through the conveyor 7 to the feeder 3. As described above, the bricks supplied are supplied to the cylinder 3 of the inner frame 3b of the feeder 3.
It is supplied to the tip side by the feeding by c. Then, as described with reference to FIGS. 8 to 10, a new brick 51a is stacked on the previously stacked bricks 51, and the bricks 51e in the front row are held so as to hit the bricks 51e exactly.

Simultaneously with the completion of feeding the brick, the electric motor 4g of the crimping device 4 is operated to run the belt 4f,
The crimping device 4 is moved to the ceiling side together with the feeding device 3. The amount of movement at this time is the amount by which the auxiliary pressing roller 4i moves to a position where it comes into contact with the inner wall side of the newly installed brick, and the brick fed out by this is restrained to the iron shell 51 side by the crimping device 4. After the brick is delivered, a new brick is further supplied from the conveyor 7 to the feeder 3, and the brick is fed from the feeder 3 and the crimping device 4 presses the iron shell 51 side by the same procedure. Will be replaced.

Here, the feeding device 3 and the crimping device 4 are located in the lower left (lower right in the case of the right arrangement) at the beginning of the work, and move from the bricks one by one to the ceiling side at a constant pitch. I will do it. During this movement, the feeding device 3
The bricks are pushed toward the iron skin 50 by the auxiliary pressing roller 4i and the belt 4f, and the bricks located diagonally above can be held. Then, by loading the bricks up to the upper layer, the lower layer bricks are restrained by the weight of the upper bricks and are held without peeling from the iron skin 50. It is to be noted that FIG. 14 shows an outline of how the crimping device 4 is moved from the initial stage to the ceiling.

The pair of left and right feeding devices 3 and crimping devices 4 interfere with each other at the portion of the ceiling of the iron shell 50 located right above the support shaft 2. In addition, the distance between the bricks with less remaining varies depending on the construction conditions, and it is necessary to change the combination of the thicknesses of the bricks (the length corresponding to the circumferential direction of the iron shell 50). For this reason,
A brick on the gondola 5 is inserted into a part of the ceiling side, and by this, the entire line of the inner circumference of the iron skin 50 is lined with bricks.

When the lining of one row of bricks is completed in this way, the output shaft of the electric motor 4g is rotated in the reverse direction to cause the belt 4f to run along the row of bricks while moving the feeding device 3 and the crimping device 4 to the lower side. Move to. Then, after the floor side bricks laid in advance are lowered, the traveling carriage 1 is moved forward and set to the lining position of the next row, and the same work is performed thereafter.

As described above, only by supplying the brick 51 to the feeding device 3, the lining of the brick 51 on the iron skin 50 can be mechanically performed except for the ceiling portion thereof. Therefore, compared to the conventional work method, the work load is light and the work efficiency is significantly improved.

Here, when the traveling carriage 1 is fed into the iron skin 50 and the bricks are stacked by the feeding device 3 and the crimping device 4, the tips of the feeding device 3 and the crimping device 4 do not interfere with the iron skin 50. It is necessary to do so. Therefore, a folding mechanism is provided for the feeding device 3 and the crimping device 4 around the support shaft 2.

FIG. 15 is a skeleton diagram showing an outline of this folding mechanism.

The two arms 4a for the crimping device 4 connected to the support shaft 2 have a structure in which one of them is attached so as to be movable in the axial direction of the support shaft 2, and the arms 4a are arranged in the axial direction of the support shaft 2. It can be set to a remote state.

FIG. 15 (a) shows a working posture when stacking bricks, and an arm 4 integrally provided with a feeding device 3 with respect to a spindle 2 supported by two lifting cylinders 2a and 2b.
a stands up. When the brick stacking work is completed, one arm 4a is moved to the right of the work position as shown in FIG. 6B, and the crimping devices 4 provided at the tips of the respective arms 4a move in the rotating direction. Avoid interference.

Next, as shown in FIG. 6C, the support shaft 2 is raised by the elevating cylinders 2a and 2b, and the crimping device 4 is moved to a level where it does not interfere with the traveling carriage 1 when it is rotated downward. Then, by rotating the base ends of the respective arms 4a around the support shaft 2, the two crimping devices 4 are folded above the traveling carriage 1 in a posture of being suspended from the arms 4a as shown in FIG. be able to.

Further, after the bricks 51 are stacked by the crimping device 4, a portion of the upper end portion of the iron skin 50 which cannot be worked by the left and right crimping devices 4 is piled up by a worker who is placed on the gondola 5.

FIG. 16 is a schematic view showing an example of the work procedure of the final brick building.

As shown in FIG. 7A, after the left and right feeding devices 3 are set in a position substantially above the iron skin 50, the gondola 5 is moved.
An operator riding on the bridge bridges the support bridge 9 on the upper ends of the feeding devices 3 as shown in FIG. After that, the worker places the brick 51 on the support bridge 9 so as to fill the remaining gap, thereby covering the inner front portion of the iron skin 50 with the brick 51. At this time, if a gap remains between the bricks, an iron plate with an appropriate thickness is inserted into this gap.

As another example of the structure of the support bridge 9, the structure shown in FIG. 17 can be utilized.

In FIG. 9A, a tube 9a made of rubber or the like is arranged on the upper surface of the support bridge 9 to form a brick 5
This is an example in which compressed air is supplied to the tube 9a after 1 is placed. By providing such a tube 9a, the brick 51 on the support bridge 9 can be pressed against the iron skin 50 side, and it becomes possible to stack bricks with even better finish.

Further, (b) of the figure is an example in which one end side of the support bridge 9 is pivotally attached to the tip of one feeding device 3 and is connected to this feeding device 3 side by a cylinder 9b. With this configuration, the operator does not have to lift or remove the support bridge 9, and if the support bridge 9 is pushed upward by the cylinder 9b, the brick 51 can be pressed against the iron skin 50 side. Becomes

Further, FIG. 18 shows an example in which a space left for the final brick stack is created and the preceding stacked brick 51 can be tightly crimped to the iron skin 50.

A holder 10 is provided on the upper surface of the support bridge 9.
A cylinder 10 supported by a is provided. This cylinder 10 is a holder 10a around which a feeding operation can be manually performed to the front side in the figure. The receiving seat 10b at one end of the cylinder 10 is abutted against the left brick 51, and the tip of the rod 10c is connected to the right brick. It is set on the support bridge 9 so that it can abut against 51.

After the work of stacking the bricks 51 by the feeding device 3 is completed, the support bridge 9 is set on the tip of the feeding device 3 as shown in the figure, and the cylinder 10 is held.
Positioned between the bricks 51 by a. Then, by operating the cylinder 10 to extend the rod 10c, the bricks 51 already stacked are pushed and tightened. After this, the rod 10c is retracted to hold the holder 10a.
When you manually turn the cylinder 10 around and push it toward you,
A space is obtained on the upper surface of the support bridge 9, and the final brick work can be performed as in the case of FIG.
