Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator sheave groove cleaning device for cleaning a sheave groove of a sheave on which a rope such as a main rope is wound, when necessary. About. 2. Description of the Related Art FIG. 3 is a perspective view showing an elevator sheave. In the drawing, 1 is a machine platform, 2 is a bearing platform provided on the machine platform 1, 3 is a sheave supported by the bearing platform 2 and provided with a plurality of rope grooves 4 on a rim surface, and 5 is a sheave. 4 is a rope consisting of an elevator main rope wound around each of the four. In the elevator sheave 3 constructed as described above, the rope groove 4 is cleaned as described below. That is, the portion of the rope groove 4 where the rope 5 is not wound is rubbed and cleaned by a cleaning tool such as a waste cloth, and then the sheave 3 is slightly rotated, that is, the elevator is driven for a short distance, An operation of cleaning other portions of the rope groove 4 where the rope 5 is not wound is performed. In the above-described cleaning operation of the rope groove 4 of the conventional sheave 3, the rope groove formed between the machine base 1 and the rope 5 as shown in FIG. (4) Since the space for the cleaning work is narrow, there is a problem that the work with the cleaning tool is not easy, and a short operation of the elevator is required, so that the cleaning is troublesome. SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a rope for an elevator sheave that can easily clean a rope of a sheave on which a rope such as a main rope is wound. It is intended to obtain a groove cleaning device. [0006] In an elevator sheave cleaning device for an elevator sheave according to the present invention, a sheave provided with a sheave and a fixed body corresponding to the sheave is temporarily provided with one side. A mounting rod provided on the other side of the mounting arm, the length of which is arranged parallel to the rotation axis of the sheave, and which is arranged away from the rim surface of the sheave; A holding member held by the holding member and capable of moving back and forth with respect to the rim surface of the sheave and urged by an urging member in a direction approaching the rim surface of the sheave; And a cleaning spatula made of a viscoelastic material, which is attached to the sheave and rubs the sheave groove of the sheave. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment 1 and 2
1 is a diagram showing an example of an embodiment of the present invention. FIG. 1 is a perspective view, and FIG. 2 is a front view of FIG. 1 and 2, an elevator sheave is pivotally attached to the machine base as in FIG. In the figure, reference numeral 3 denotes a sheave pivotally supported by the bearing base 2 and provided with a plurality of rope grooves 4 on a rim surface, and a rope 5 is wound around each of the rope grooves 4. Reference numeral 6 denotes a fixed body provided corresponding to the sheave 3, and a mounting plate 7 and both ends thereof are fastened to the mounting plate 7, arranged parallel to the rim surface of the sheave 3, and approaching the outer surface of the sheave 5. It is constituted by a rope stopper 8 composed of double screw bolts arranged in a line. Reference numeral 9 denotes a mounting arm, one side of which is fastened via a long hole 10 to a thread portion of the fixing member 6 in the rope stopper 8 and is temporarily provided. Reference numeral 11 denotes a support rod, which is fastened to the other side of the mounting arm 9 via screw portions provided at both ends, has a length arranged in parallel with the rotation axis of the sheave 3, and is separated from the rim surface of the sheave 3. Is located in the position. Numeral 12 denotes a holding body, one side of which is fixed to the support rod 11 and is formed corresponding to the rim surface width of the sheave 3 and is arranged to face the rim surface of the sheave 3 and the other side has a groove. A hole 13 is provided. Reference numeral 14 denotes a holder, and the pins 15 on both ends are fitted into the slots 13 of the holder 12 so as to form a gap, and the holder 15
The sheave 3 is provided so as to be able to advance and retreat with respect to the rim surface of the sheave 3. Reference numeral 16 denotes an urging member comprising a compression coil spring.
Both ends are connected to the holder 12 and the holder 14, respectively, and urge the holder 14 in a direction approaching the rim surface of the sheave 3. Reference numeral 17 denotes a cleaning spatula made of a plate material made of a viscoelastic material such as rubber. The base is fastened to the holder 14 and formed on the edge corresponding to the rim surface of the sheave 3 so as to correspond to the rope groove 4. Rope groove 4
Is provided. Using the rope groove cleaning device of the elevator sheave constructed as described above, the rope groove 4 is cleaned as described below. That is, the mounting arm 9 is fastened to the fixing portion 6 via the elongated hole 10 and is temporarily provided. Then, the holding body 12 and the holding tool 14 are arranged at positions corresponding to the positions where the rope 5 of the rope groove 4 is not wound, and the cleaning spatula 17 is arranged to face the rope groove 4. As a result, the cleaning spatula 17 is pressed against the rope 4 by the urging member 16 in the state shown in FIG.
By continuously operating the elevator at a low speed in this state, the convex portion 18 of the cleaning spatula 17 is rubbed in the rope groove 4 and cleaned. Therefore, even if the space for cleaning the rope groove 4 formed between the machine base 1 and the rope 5 is narrow, the rope groove 4 of the sheave 3 can be cleaned easily and in a short time. Further, since the cleaning operation is obtained by continuously operating the elevator at a low speed, it is possible to improve the work efficiency without requiring a complicated work for the cleaning operation. In addition, the mounting arm 9 with respect to the fixed body 6 is
The angle between the mounting arm 9 and the moving direction of the cleaning spatula 17 can be appropriately set according to the position of the mounting arm 9 and the fastening state between the mounting arm 9 and the support rod 11, so that the sheave 3 corresponding to different sizes can be set. The holder 12, the holder 14, the cleaning spatula 17 and the like can be easily arranged at required positions. Therefore, by preparing one type of rope cleaning device, various sheaves 3 can be easily cleaned, and costs can be reduced. As described above, the present invention provides a sheave provided with a rope groove, a mounting arm temporarily provided on one side of a fixed body corresponding to the sheave, and the other side of the mounting arm. The support rod is provided with a longitudinal length parallel to the rotation axis of the sheave, and is disposed away from the rim surface of the sheave, a holder provided on the support rod, and held by the holder. And a holding tool urged by a biasing body in a direction approaching the rim surface of the sheave, and a gutter groove of the sheave mounted on the holding tool. A cleaning spatula made of a viscoelastic material to be rubbed is provided. [0015] Thus, the mounting arm is fastened to the fixing portion and temporarily provided, and the holding body and the holding tool are arranged at positions corresponding to the locations where the ropes of the rope grooves of the sheave are not wound. It is arranged facing the groove. The elevator is continuously operated at a low speed in a state where the cleaning spatula is pressed against the rope by the urging body, so that the sheave is rotated and the cleaning spatula is rubbed and cleaned. For this reason, even if the space for the rope groove cleaning work formed between the machine base on which the sheave is pivoted and the rope is narrow, it can be easily cleaned, and the rope of the sheave can be cleaned in a short time. This has the effect of facilitating cleaning work. In addition, since the sheave can be cleaned by continuously operating the elevator at a low speed, there is an effect that the cleaning work does not require complicated work and the work efficiency is improved.
