Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning device for an elevator guide rail that guides an elevator car or a counterweight.

[Conventional technology]

Generally, in an elevator, in order to guide a movable body such as a car or a counterweight, a guide shoe provided on the movable body is movably fitted into a guide rail provided upright in a hoistway. Also,
An oiler is provided on the movable body side, and supplies oil from the oiler to the fitting portion between the guide shoe and the guide rail to move the movable body more smoothly.

However, in elevators that have been used for many years, dirt and the like adhere to the lubricating oil from the oiler, and foreign matter such as so-called oil scum adheres to the surface of the guide rail. If the amount of foreign matter increases, it will affect the fit with the guide rail, make the elevator ride uncomfortable, or cause abnormal noise, so the guide rail needs to be cleaned regularly. .

Conventionally, when cleaning guide rails, a worker climbs onto the ceiling of a moving object such as a car and cleans the surface of the guide rail with a rag while operating the object at low speed. This resulted in poor work efficiency and required work that was accompanied by oil stains. On the other hand, Utsukai 59-
As shown in Japanese Patent No. 116366, a cleaning device for cleaning the surface of a guide rail by raising and lowering a car has also been proposed, and this is shown in FIG.

In this cleaning device, plate-shaped sliding bodies 2, 3, and 4 are fastened to the upper part of a frame 1 so as to sandwich the side surfaces of a guide rail 5, and these plate-shaped sliding bodies
The brushes 7, 8, and 9 which are in constant contact with the surface of the guide rail 5 are attached to another frame 6 to remove dust and the like adhering to the surface of the guide rail 5. By attaching such a cleaning device to the car and moving the car up and down, the plate-shaped sliding bodies 2, 3, 4 are removed.
and guide rail 5 by brushes 7, 8, 9.
Prevent dirt from adhering to the surface.

[Problem that the invention attempts to solve]

Since the conventional cleaning device described above is intended for cleaning guide rails that do not use lubricating oil, it cannot be applied to cleaning guide rails that have foreign matter such as oil scum attached to them.

An object of the present invention is to provide an elevator guide rail cleaning device that can easily remove foreign matter adhering to the surface of the guide rail with a simple configuration.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an elevator guide rail comprising a pair of removal members which are respectively press-contacted to both sides of the guide rail on the side of the guide shoe fitted so as to be guided along the guide rail. In the cleaning device, the cleaning device serves as an elastic member that holds both the removing members and applies a pressing force to both the removing members to apply a pressing force to both the side surfaces of the guide rail, and the removing member is removed by the removing members. A receiving member is provided to collect the foreign matter,
The present invention is characterized in that this receiving member is attached to an oiler provided on the guide shoe side so as to be elastically deformable.

[Effect]

Since the present invention is constructed as described above,
Since the removal member is applied with a pressure contact force against the side surface of the guide rail by the pressure contact force applying elastic member, a small thin plate itself can be used, and moreover, it can be attached to the guide shoe side by an elastic attachment means. Since the elastic member is elastically deformed from the elastic mounting means to allow the deformation of the pressing force applying elastic member, an effective pressing force can be obtained at all times, thereby providing a cleaning device that easily removes foreign matter with a simple configuration. can get.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view of the cleaning device seen from above, showing the state before it is attached to a guide shoe (not shown). As will be understood from the description below, the receiving member 10, which is an elastic member for applying pressure contact force, is composed of a cardboard box without a top lid, and includes a bottom portion 11, a pair of upright portions 12 and 13, and an end of the upright portion. It consists of standing parts 14 and 15 that bridge the parts. The upright portion 15 is separated in the middle to form a pair of separated upright portions 15a,
15b, and its separate standing portions 15a,
The facing portions 15b are sloped so that the facing distance becomes smaller toward the top. As can be seen from FIG. 3, which is a bottom view of the cleaning device, the bottom part 11 has a width that is approximately equal to the distance between the separation upright parts 15a and 15b on the bottom part 11 side, and a length of the upright part 13, in order to insert the guide rail. For example, a notch 11a is formed that cuts about half way. Therefore, the receiving member 10 has separate upright portions 15a and 15b.
When an external force is applied to open the gap, a restoring force is generated to maintain the state shown in FIG. 2 due to the shape and structure of the receiving member, resulting in elasticity as a whole.
Furthermore, the bottom part 11 has a notch 11 as shown in FIG.
A folded upright part 11b is formed on the upright part 14 side in a, and as will be understood from the explanation below, when the opposing sides of the removal members 16 and 17 are raised upward in FIG. 1, they are folded back so as to stand up in the same direction. ing.

The bottom side of the plastic bag 20 is attached to the upright part 14 opposite to the upright part 15 by adhesive or other fixing means. Further, one end 18a of an elastic attachment means 18 made of an elastic member such as rubber is fixed to the upright portion 13 by a suitable fixing means.
A fixing fitting 19 is attached to the other end of the elastic attachment member 18 and is removably engaged with the upright portion 12 .

Further, the above-mentioned notch 11a is provided on the upper surface of the bottom portion 11.
A pair of removal members 16 and 17, each of which is an elastic body, is arranged so as to cover the removal members 16, 17.
17 are fixed to the bottom part 11 at opposite sides with their opposing sides overlapped with each other by suitable fixing means. Opposite sides of the removal members 16 and 17 are sloped surfaces that extend toward the opposite side as they approach the upright portion 15 side. This slope and the overlapping length on the opposite side are determined by conditions described later. Further, the removal members 16 and 17 on the side of the standing portion 15 are separated from the standing portion 15.
Engagement portions 16a and 17a are formed between a and 15b, extending in the axial direction of the upright portions 12 and 13 and protruding to the back side of the separation upright portions 15a and 15b. Therefore, when the opposite sides of the removal members 16 and 17 are lifted upward and elastically deformed and opened, and the guide rail is inserted between them, the engaging portions 16a and 17 are opened.
a promotes elastic deformation of the receiving member 10 via the separated upright portions 15a, 15b, and eventually this elastic force is applied to the removal members 16, 1 via the separated upright portions 15a, 15b.
7 acts as a force to press against the guide rail. As can be seen from this explanation, the elastic pressure of the removal members 16 and 17 is reinforced by the elastic force of the receiving member 10, so the removal members 16 and 17 are made of relatively small, thin, and not very elastic plastic thin plates. Can be used.

FIG. 1 shows the above-mentioned cleaning device in use. An oiler 23 is provided on the side of a moving body such as a car or a counterweight, and the cleaning device is attached to this oiler 23 by an elastic attachment means 18. ing.

The pair of removal members 16 and 17 are opened by lifting their opposing sides upward, and the guide rail 5 is sandwiched between them. At this time, the opposing sides of the removal members 16 and 17 are formed into inclined surfaces, and the receiving member 10 separates the upright portion 15 into two separated upright portions 15a and 1.
5b and because the receiving member 10 itself is elastically deformed, the opposing tips of the removal members 16 and 17 come into contact with the side surface 5a of the guide rail 5 over the entire length. Removal member 1
The elastic deformation of 6, 17 causes the engaging portions 16a, 17
a to the separated upright parts 15a, 15b and the bottom part 11, further promoting elastic deformation of the receiving member 10, and eventually the elastic force of the receiving member 10
5a, 15b and the removal member 1 through the bottom part 11.
6, 17. For this reason, the removal member 16,
The opposite end of the guide rail 17 is pressed against the guide rail 5 with a force greater than its own elastic force.
The elastic deformation of the receiving member 10 as described above acts more effectively depending on the attachment structure to the oiler 23. In other words, the receiving member 10 has its upright portions 12,1
Since it is attached to the oiler 23 using the elastic attachment means 18 connected between the two parts, when the receiving member 10 tries to elastically deform to lift up the separation standing parts 15a and 15b, the elastic attachment means 18 is Therefore, the deformation is allowed without being suppressed, and as a result, the removal member 1 is removed from the side surface of the guide rail.
The pressure contact state of 6 and 17 is maintained well.

In this state, when the movable body on the guide shoe side is driven upward, the removal members 16 and 17 remove foreign matter such as oil scum adhering to the side surface 5a of the guide rail 5, and collect the removed foreign matter in the receiving member 10. Go. The opposing parts of the separation standing parts 15a and 15b, which were open in the state shown in FIG. Since there is a folded upright portion 11b on the top surface 5b side, foreign objects can be removed from the receiving member 10.
It can be stored without spilling.

After the deposit removal work is completed, the elastic attachment means 18
When the cleaning device is removed from the oiler, deposits accumulate on the receiving member 10, resulting in a condition as shown in FIG. When disposing of this cleaning device, an operator inserts his/her hand through the opening of the plastic bag 20 shown in FIG.
Therefore, the worker does not directly touch the oil residue and does not get his hands dirty.

In the above embodiment, the receiving member 10 is made of a general cardboard box, but if the cardboard box is made of a cardboard box whose surface is treated to be oil-resistant, the receiving member 10 for oil scum etc.
The elasticity of the receiving member 10 can be maintained even when a large amount is stored in the container for a long time and when it is reused.

[Effect of idea]

As explained above, in the present invention, by using the receiving member that supports the removal member as an elastic member that applies pressure contact force, the pressure contact force necessary for removing foreign objects can be obtained even if the removal member is made small and thin. Moreover, since the attachment to the guide shoe side is done by the elastic attachment means, the elastic deformation of the pressure applying force applying elastic member is not impaired due to the expansion of the elastic attachment means, and the guide rail can be easily attached to the guide rail with a simple structure. It is possible to remove foreign matter adhering to the surface without leaving any oil stains.
