Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sheave groove cleaning device for cleaning the sheave groove of a traction machine for a rope elevator.

[Prior Art] Generally, in a rope elevator, a plurality of ropes are hung in grooves of a sheave provided in a traction machine, and the sheave is rotated by an electric motor to move the car up and down via the ropes. ing. When an elevator constructed in this manner is used for a long period of time, rope oil oozing from the rope, dirt, dust, and other foreign substances often adhere to the grooves of the sheave. As a result, the friction between the sheave groove and the rope decreases, which may cause the rope to slip, so it is necessary to periodically clean the sheave groove to prevent such slippage.

Therefore, as a sheave groove cleaning device for cleaning this sheave groove, for example, as shown in Japanese Utility Model Application Laid-Open No. 61-130578, a urethane rubber formed so as to be able to engage with the sheave groove, and a urethane rubber fixed to a member of the traction machine are used. It has been proposed that the sheave is provided with an L-shaped fitting that supports the urethane rubber, and the sheave is rotated while the urethane rubber is engaged with the sheave groove.

[Problems to be solved by the invention] By the way, the above-mentioned conventional sheave groove cleaning device has a problem of high manufacturing cost because it is equipped with urethane rubber as an engaging part for removing foreign matter adhering to the sheave groove. It was hot. Another problem was that foreign matter removed from the sheave groove by the engaging portion spilled onto the floor around the traction machine, requiring a great deal of effort to clean the contaminated floor.

The present invention was developed in view of the actual situation in the prior art as described above, and its purpose is to provide a sheave that is inexpensive to manufacture and that does not contaminate the area around the traction machine with foreign matter removed from the sheave groove. To provide a sheave groove cleaning device capable of cleaning grooves.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a sheave groove cleaning device that engages with a groove of a sheave and cleans the groove, which is formed so as to be able to engage with the groove, The device is configured to include a receiving member having an engaging portion for removing foreign matter adhering to the groove, a casing portion for receiving the foreign matter removed by the engaging portion, and a handle.

[Operation] Since the present invention is configured as described above, the receiving member is arranged so that the engaging portion fits into the groove while gripping the handle, and the receiving member is rotated along the sheave groove. By rotating the sheave, the engaging portion slides on the surface of the groove, and foreign matter adhering to this surface is removed. The removed foreign matter is then received by the housing. Thereby, the sheave groove can be cleaned without contaminating the area around the traction machine due to foreign matter removed from the sheave groove.

[Example] Hereinafter, the sheave groove cleaning device of the present invention will be explained based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the sheave groove cleaning device of the present invention, and FIG. 2 is an explanatory diagram showing a state in which the sheave groove cleaning device of FIG. 1 is cleaning the sheave groove.

First, the second section shows the state in which the sheave groove is to be cleaned.
In the figure, 1 is a traction machine, 2 is a sheave rotatably provided in the traction machine 1 and driven by an electric motor (not shown), and 2a is provided on the outer periphery of the sheave 2, and is formed in a V-shaped cross section. A plurality of ropes 3 each having a basket and a counterweight (not shown) connected to each end thereof, and a plurality of ropes having an intermediate portion hung in the groove 2a of the sheave 2;
Reference numeral 5 indicates a sheave groove cleaning device for cleaning the rope oil oozing from the rope 3 and foreign matter such as dust, and 5 cleaning the groove 2a.

Next, in FIG. 1 showing the structure of this sheave groove cleaning device 5, 6 is a bottom plate, 7 is a front side plate provided at the front end of the bottom plate 6, 8 is provided on the upper part of the front side plate 7, and the groove shown in FIG. an engaging portion that is formed to protrude so as to be able to engage with the groove 2a, and that removes foreign matter adhering to the groove 2a;
Reference numerals 9 and 10 are side plates that are provided on both sides of the bottom plate 6, one end of which is connected to the front side plate 7, and the other side of which is gradually narrowed. A housing portion 13a is formed to receive the foreign matter 4 removed by the engaging portion 8. Further, 11 is a handle formed by overlapping the other ends of the side plates 9 and 10, and 12 is a plastic bag whose bottom portion is fixed to the handle 11 with adhesive or the like. Further, this receiving member 13 is made of, for example, general cardboard.

In this embodiment, foreign matter 4 attached to the sheave 2
To remove this, the operator first stops the sheave 2 of the traction machine 1, and while holding the handle 11 of the sheave groove cleaning device 5, as shown in FIG. The sheave groove cleaning devices 5 are disposed below the sheave 2 so as to fit into the grooves 2a. Next, this sheave groove cleaning device 5 is installed in the groove 2.
When the sheave 2 is rotated along the groove 2a or when the sheave 2 is rotated at low speed by the drive of an electric motor, the engaging portion 8 is rotated along the groove 2a.
The foreign matter 4 adhering to the surface is removed by sliding on the surface. Further, the removed foreign matter 4 is guided to the front side plate 7 and received by the housing portion 13a. After cleaning the groove 2a in this way, the worker inserts his hand through the opening of the plastic bag 12,
While turning this plastic bag 12 over, hold the handle 1
1. The housing part 13a and the engaging part 8 are sequentially wrapped in a plastic bag 1.
Put it in 2. Then, the sheave groove cleaning device 5 is disposed of with the housing portion 13a that has received the foreign matter 4 placed in the plastic bag 12.

In the embodiment configured in this manner, the foreign matter 4 removed from the groove 2a of the sheave 2 is received by the housing portion 13a, so that it is possible to prevent the floor etc. around the traction machine 1 from being contaminated. In addition, since the receiving member 13 containing the foreign matter 4 is disposed of by putting it in the plastic bag 12, the operator can directly touch the foreign matter 4.
You don't have to touch it, and you can prevent your hands from getting dirty.
Furthermore, the receiving member 13 including the housing portion 13a, the handle 11, and the engaging portion 8 is made of cardboard,
Manufacturing costs such as material costs and processing costs can be reduced.

Note that if the surface of the cardboard forming the receiving member 13 is treated to make it oil-resistant, the receiving member 13 will be free from foreign matter 4.
It is also possible to store the water for a long time or to reuse the sheave groove cleaning device 5. In addition, in order to assemble the receiving member 13 made of cardboard, the bottom plate 6, the front plate 7, and the side plates 9 and 10 may be arranged in a row and bent, pasted with glue or double-sided tape, or joined with pins. . Furthermore, although this embodiment illustrates a case in which there are three grooves 2a, the present invention is not limited to this, and a sheave having a number of grooves other than three may also have engaging portions corresponding to the number of grooves. may be provided. Alternatively, if a number of engaging portions different from the number of grooves is provided, and the number of engaging portions is smaller than the number of grooves, all the grooves may be cleaned in multiple steps.

[Effects of the invention] Since the present invention is configured as described above, the manufacturing cost is low, and the area around the traction machine can be prevented from being contaminated by foreign matter removed from the sheave groove. Moreover, the sheave groove can be cleaned at a low cost.
