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 moving object such as a car or a counterweight, a guide shoe provided on the moving object is movably fitted into a guide rail provided upright in a hoistway. Further, 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, thereby moving the movable body more smoothly.

However, in elevators that have been used for many years, dirt and other substances adhere to the oil from the oiler.
Foreign matter such as so-called oil scum will adhere to the surface of the guide rail. If the amount of this foreign material increases, it will affect the fitting with the guide shoe.
Guide rails need to be cleaned regularly because they can make the elevator ride uncomfortable or cause abnormal noise.

Conventional guide rail cleaning involves a worker riding on the ceiling of a moving object such as a car while driving at a constant 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, in 1987,
As shown in Japanese Patent No. 116366, a cleaning device was proposed that 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
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 a car or the like and moving the car up and down, the plate-shaped sliding bodies 2, 3,
4 and brushes 7, 8, and 9 prevent dust and the like from adhering to the surface of the guide rail 5.

[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.

SUMMARY OF THE INVENTION 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 a guide rail with a simple configuration and by applying a large removal force.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an elevator guide rail cleaning device comprising a receiving member which receives foreign matter removed from the guide rail by a removal member and supports the removal member, the receiving member having a pair of separate upright portions formed by providing a notch in at least one of the upright portions and being an elastically deformable box body without an upper lid, and the pair of removal members having engagement portions near the bottoms of the pair of separate upright portions which apply an elastic deformation force to the receiving member when the removal member deforms.

[Effect]

Since the present invention is constructed as described above,
Rather than having the worker directly remove the foreign matter attached to the guide rail, the foreign matter can be removed using a removal member and received by the receiving member.Moreover, by elastically deforming the removal member along the side of the guide rail, The receiving member is elastically deformed via the engaging portion, and the elastic force of the receiving member is applied to the removing member to strengthen the pressing force, so that the removing member can remove foreign matter with a large removing force.

〔Example〕

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

FIG. 2 is a plan view showing the cleaning device 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 and a pair of upright portions 12 and 13.
and standing portions 14 and 15 bridging the ends thereof. 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 sloped surfaces that reduce the facing distance toward the top. is attached. The third figure is a bottom view of the cleaning device.
As can be seen from the figure, in order to insert the guide rail, a cut is made in the bottom part 11 with a width approximately equal to the opposing distance of the separation standing parts 15a and 15b on the bottom part 11 side, for example, to about half the length of the standing part 13. A deep notch 11a is formed. Therefore, the receiving member 10
When an external force is applied to open the separation standing parts 15a and 15b, a restoring force is generated to maintain the state shown in Fig. 2 due to the material and shape of the receiving member 10, and the whole shows elasticity. Become. Furthermore, as shown in FIG. 3, the bottom portion 11 is formed with a folded upright portion 11b on the side of the upright portion 14 in the notch 11a, and as will be understood from the description below, the removal member 1
The opposite sides of 6 and 17 are folded back so that they stand up in the same direction when lifted upward in FIG.

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, one end 1 of a band 18 made of an elastic member such as rubber is attached to the upright portion 13.
8a is fixed by suitable fixing means, and a fixing fitting 19 is attached to the other end of this band 18. The other end of the band 18 is removably latched to the upright portion 12 by this fixture 19.

In addition, the above-mentioned notch 11 is provided on the upper surface of the bottom portion 11.
A pair of removal members 16 and 17, which are themselves elastic bodies, are arranged so as to cover a, and the removal members 16 and 17 overlap each other on opposite sides and attach the opposite sides to the bottom 11 in a suitable manner. It is fixed by a 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 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 rear side of the separation upright portions 15a and 15b. Therefore, when the opposing 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 1
7a comes into contact with the lower part of the opposing inclined surface of the separation upright parts 15a, 15b, so that the separation upright parts 15a, 15b
The elastic deformation of the receiving member 10 is promoted through the
This elastic force acts as a force that presses the removal members 16, 17 against the guide rail via the separation upright portions 15a, 15b.

As can be seen from this description, the removal members 16,1
When the receiving member 7 is elastically deformed along the side surface of the guide rail, the force is applied via the engaging portions 16a and 17a, and the receiving member 10 is elastically deformed. As a result, a large removing force is applied to the removal members 16, 17, so that relatively thin plastic plates or the like which are relatively thin and not very elastic can be used as the removal members 16, 17.

FIG. 1 shows the usage state of the above-mentioned cleaning device, in which an oiler 23 is provided on the side of a moving object such as a car or a counterweight.
A cleaning device is attached by a band 18.

The pair of removal members 16 and 17 lift their opposing parts upward to open, and the guide rail 5 is sandwiched between them. At this time, the opposite 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
The force is transmitted to the separation upright portions 15a, 15b and the bottom portion 11 through
A large elastic force of 0 is transmitted to the removal members 16, 17 via the separation upright portions 15a, 15b and the bottom portion 11. For this reason, the removal member 16,1
The opposite end of the guide rail 7 is brought into contact with the guide rail 5 with a force greater than its 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. Considering only this effect, the facing surfaces of the separation upright portions 15a and 15b may be vertical, for example, but by making them sloped as shown in the figure, the removal members 16 and 17 pressed against the guide rail 5 and the separation upright portion 15a , 15b is made smaller. Also, the bottom 11
The folded upright portion 11b formed in is also slightly raised upward.

In this state, when the movable body on the shoe side is driven upward, the removal members 16 and 17 are removed from the guide rail 5.
Foreign matter such as oil scum adhering to the side surface 5a of the device is removed, and the removed foreign matter is collected in the receiving member 10. Separation standing portion 15 that was open in the state shown in Figure 2
The opposing portions of a and 15b are almost closed by the inclined surfaces and the deformation of the removal members 16 and 17 as shown in FIG. The top surface 5b of the guide rail 5 also collects foreign matter without scattering it from the receiving member 10 due to the folded upright portion 11b.

After the foreign matter removal work is completed, when the band 18 is removed and the cleaning device is removed from the oiler 23, foreign matter is accumulated in the receiving member 10, as shown in FIG. 2. When disposing of this cleaning device, an operator inserts his hand through the opening of the plastic bag 20 shown in FIG. 2, grasps 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.

[Effect of idea]

As explained above, the present invention includes a receiving member that receives the foreign matter removed from the guide rail by the removing member and supports the removing member, and the receiving member has a notch in at least one upright portion. The above-mentioned pair of removal members are placed near the bottoms of the pair of separation upright parts to form a pair of separated upright parts and an elastically deformable box body without a top lid. Since the engaging part is formed to apply elastic deformation force of By engaging with the receiving member, a large elastic deformation force is applied to the receiving member, so that by adding the restoring force of the receiving member at this time, a large removing force can be applied to the removing member to remove the foreign object. .
