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 shoe, making the elevator ride uncomfortable or causing abnormal noise, so it is necessary to regularly clean the guide rail. be.

Conventional guide rail cleaning involves a worker riding on the ceiling of a moving object such as a car while driving the car at low speed.
The surface of the guide rail was being cleaned with a rag. This resulted in poor work efficiency and required work that was accompanied by oil stains. On the other hand, Utsukai Showa 59-
As shown in Japanese Patent No. 116366, a cleaning device has been proposed which cleans the surface of a guide rail by raising and lowering a car, and this device 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
It is constructed by attaching brushes 7, 8, and 9 that are in constant contact with the surface of the brush. By attaching such a cleaning device to a car or the like and driving the car upward, dirt and the like are removed from the surface of the guide rail 5 by the plate-shaped sliding bodies 2, 3, 4 and the brushes 7, 8, 9. I try not to.

[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 remove foreign matter adhering to the surface of the guide rail.

[Means for solving problems]

In order to achieve the above object, the present invention includes a pair of removal members that press against the side surfaces of the guide rail, and a receiving member that receives the foreign matter removed from the guide rail by the removal members and supports the removal member. and means for attaching the receiving member to the guide shoe side.

[Effect]

Since the present invention is constructed as described above,
Foreign matter attached to the guide rail can be removed using a removal member rather than being removed directly by the worker, and since the removed foreign matter is received by the receiving member, cleaning work can be done without contaminating the vicinity of the guide rail or the hoistway. can be done.

〔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, showing the state before it is attached to a guide shoe (not shown). The receiving member 10 is composed of a cardboard box without an upper lid, and includes a bottom portion 11, a pair of upright portions 12 and 13,
It consists of upright parts 12 and 13 that bridge the ends thereof, and upright parts 14 and 15 that bridge the end parts.
The upright portion 15 is separated in the middle to form a pair of separated upright portions 15a and 15b, and the opposing portions of the separated upright portions 15a and 15b are tapered so that the opposing distance becomes smaller as they move upward. is attached. As can be seen from FIG. 3, which is a bottom view of the cleaning device, the bottom portion 11 of the separating upright portions 15a and 15b is provided in order to insert the guide rail.
A notch 11a is formed with a width approximately equal to the opposing distance on the sides and cut to, for example, about half the length of the upright portion 13. Therefore, when an external force is applied to the receiving member 10 so as to open the space between the separated standing portions 15a and 15b, the receiving member 10 will be moved to the second position depending on the material and shape of the receiving member 10.
A restoring force is generated to maintain the state shown in the figure, and the entire structure exhibits elasticity. Furthermore, the bottom 11 has a third
As shown in the figure, the upright portion 14 in the notch 11a
A folded upright portion 11b is formed on the side, and as will be understood from the explanation below, the removal members 16 and 17 are folded back so that when the opposite sides are raised upward in FIG. 11, they stand up in the same direction. .

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. Also, the standing portion 13
One end 18a of a band 18 made of an elastic member such as rubber is fixed to the band 18 by suitable fixing means, and a fixing fitting 19 is attached to the other end of the band 18. The other end of the band 18 is removably latched to the upright portion 12 by this fixture 19.

Further, the above-mentioned notch 11 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 a. It is fixed by suitable fixing means. The opposite sides of the removal members 16 and 17 are
The closer it gets to the upright portion 15, the longer the slope extends toward the opposite side. The overlapping length of this slope and the opposite side is determined by conditions described later. Further, the removal parts 16 and 17 on the side of the standing part 15 are connected to the separating standing part 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 separate upright portions 15a and 15b. Therefore, when the opposing sides of the removal parts 16 and 17 are lifted upward and elastically deformed and opened, and the guide rail is sandwiched between them, the engaging parts 16a and 17 are removed.
a comes into contact with the lower part of the opposing tapered surface of the separated upright parts 15a, 15b, so that the separated upright parts 15a, 15
The elastic deformation of the receiving member 10 is promoted through the support member 10, and eventually this elastic force acts as a force that presses the removal members 16 and 17 against the guide rail via the separation upright portions 15a and 15b. As can be seen from this explanation, the elastic force of the receiving member 10 causes the removing member 16,
Since the pressure contact force of 17 is reinforced, the removal members 16,
As the material 17, a thin plastic plate or the like which is relatively thin and not very elastic can be used.

FIG. 1 shows the above-mentioned cleaning device in use. An oiler 2 is provided on the side of a moving object such as a car or a counterweight, and the cleaning device is attached to the oiler 2 by a band 18.

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, removal members 16, 17
The opposite sides of the receiving member 10 are formed into inclined surfaces, and the receiving member 10 separates the upright portion 15 into two separate upright portions 15a,
Since the receiving member 10 itself is elastically deformed by being divided into 15b, the opposing tips of the removing members 16 and 17 come into contact with the side surface 5a of the guide rail 5 over the entire length. The elastic deformation of the removal members 16, 17 causes the engagement members 16a,
The elastic force of the receiving member 10 is transmitted to the separation standing parts 15a, 15b and the bottom part 11 via the separation standing parts 15a, 15b and the bottom part 11, and further promotes elastic deformation of the receiving member 10. , 17. For this reason, removal member 1
Opposite tips of 6 and 17 are brought into contact with the guide rail 5 with a force greater than their own elastic force. At this time, the separation upright portions 15a, 15b are in pressure contact with the engaging portions 16a, 17a of the removal members 16, 17 only on the bottom 11 side, as shown. If only this effect is considered, the facing surfaces of the separation upright portions 15a and 15b may be vertical, for example, but by making them tapered as shown in the figure, the removal member pressed against the guide rail 5 when the receiving member 10 is elastically deformed. 1
The gap formed between 6, 17 and the separated standing portions 15a, 15b is made small. Further, the folded upright portion 11b formed on the bottom portion 11 is also slightly raised upward.

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 portions of the separation standing portions 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 matter is collected without falling from the receiving member 10.

Due to the fitting structure between the guide rail 5 and the guide shoe, foreign matter such as oil scum hardly accumulates on the top surface 5b of the guide rail 5. The portion 11b may be made of an elastic body like the removal members 16 and 17 and may be attached to the bottom portion 11.

After the foreign matter removal work is completed, remove the band 18 and remove the cleaning device from the oiler 2, and the receiving member 1
Foreign matter accumulates in the 0, resulting in a condition as shown in Figure 2. When disposing of this cleaning device, use the plastic bag 2 shown in Figure 2.
An operator inserts his/her hand through the opening of the plastic bag 20, grabs the receiving member 10 from inside, and wraps the receiving member 10 while turning the plastic bag 20 inside out. Therefore, the worker does not come into direct contact with foreign matter such as oil scum and does not get his hands dirty. In the above embodiment, the receiving member 10 is made of cardboard to have elasticity, but the receiving member 10 is made of plastic and is made of elastic material so that the removal members 16 and 17 themselves can generate the necessary pressing force against the guide rail. You may also have In this case, the band 18 for attaching the receiving member 10 to the oiler 2 can be attached to the oiler 2 by other common fastening means, such as bolts or the like.

FIG. 4 is a perspective view showing a cleaning device according to another embodiment, which differs from FIG. 1 in that oil absorbers 21 and 22 are arranged inside the receiving member 10. According to this embodiment, oil such as oil residue or moisture removed from the guide rail 5 is absorbed by the oil absorbers 21 and 22. Therefore, the volume of the receiving member 10 can be reduced and the number of times it can be used repeatedly can be increased.

[Effect of idea]

As explained above, the present invention supports a pair of removal members that are in pressure contact with the side surfaces of the guide rail, and also provides a receiving member for receiving foreign matter dropped from the side surface of the guide rail by the removal members. Because of this structure, it is possible to remove foreign matter such as oil scum by eliminating manual work that involves oil stains, and collect and dispose of foreign matter such as oil scum without scattering it, so the inside of the hoistway is not contaminated.
