[0035] figure 1 It is a perspective view showing the structure of the elevator rope cleaning tool of 1st Embodiment. figure 2 It is a perspective view which shows the structure of the rotating member used for the cord cleaning tool of this embodiment.

[0036] like figure 1 As shown, the rope cleaning tool 11 has a pair of bases 12a, 12b, and the pair of bases 12a, 12b is configured in two stages up and down in the axial direction of the plurality of wire ropes 10a to 10f to be cleaned. Wire ropes 10a-10f are the main ropes or compensation ropes of the elevator (refer to Figure 11 to Figure 14 ).

[0037] The base 12a is composed of an upper section 13a and a lower section 14a. Similarly, the base 12b is comprised from the upper stage part 13b and the lower stage part 14b. The base 12a and the base 12b are attached so that each wire rope may be sandwiched together from both sides of the wire ropes 10a-10f. A spacing adjustment spacer 16 is interposed between the base 1...

[0088] Figure 15 It is a perspective view showing the structure of the rotation assist mechanism included in the cord cleaning tool of the second embodiment, Figure 16 It is a perspective view which partially shows this rotation assistance mechanism. in addition, Figure 17 It is a figure showing the relationship between a rotating member and a rotation assist mechanism.

[0089] The rotation assist mechanism 40 has a plurality of rings 41 and a support member 42 that rotatably supports these rings 41 , and rotatably supports the upper-stage rotating member 15 on the side surfaces of the upper-stage portions 13 a and 13 b. The ring 41 and the support member 42 are arranged in a row on the side surfaces facing the wire ropes 10a to 10f of the upper sections 13a, 13b of the bases 12a, 12b.

[0090] In addition, although illustration is omitted here, a similar rotation assisting mechanism 40 is also provided on the lower stages 14a, 14b of the bases 12a, 12b. In this case, ...

[0095] Cleaning of the wire ropes 10a to 10f is performed by moving the wire ropes 10a to 10f in a direction in which the rotating member 15 attached to the wire ropes 10a to 10f in a zigzag shape is pressed against the bases 12a and 12b of the rope cleaning tool 11 as described above. At this time, for example, the wire ropes 10a to 10f may move in the reverse direction due to an operator's erroneous operation. In this case, there is a possibility that the rotating member 15 on the upper stage side separates from the rope cleaning tool 11 and hits, for example, Figure 11 The main sheave 102 shown waits on and causes the possibility of elevator failure.

[0096] In the third embodiment, the rope cleaning tool 11 has a function of preventing the upper stage side rotating member 15 from being separated from the rope cleaning tool 11 due to the reverse movement of the wire ropes 10a to 10f.

Abstract

The invention provides an elevator rope cleaning device, which is used for cleaning a steel rope, and is capable of effectively removing lubricating resin from a plurality of steel ropes. The rope cleaning device (11) includes a pair of bases (12a, 12b) and a plurality of rotating members (15). The bases (12a, 12b) each include an upper tier and a lower tier arranged in an axial direction of a plurality of wire ropes (10a-10f) to be cleaned, and are installed to interpose the wire ropes (10a-10f) 10 altogether therebetween from sides. A spacer (16) for interval adjustment is interposed between the bases (12a, 12b). The rotating members (15) are rotatably attached to the wire ropes (10a-10f) zigzag in correspondence with positions of the upper tiers (13a, 13b) and the lower tiers (14a, 14b) of the bases (12a, 12b). The rotating members (15) are brought into contact with the upper tiers (13a, 13b) and lower tiers (14a, 14b) of the bases (12a, 12b) by movement of the wire ropes (10a-10f) in one direction and rotate, thereby removing grease.

Description

technical field [0001] This application is based on Japanese Patent Application No. 2012-123753 (filing date: May 30, 2012), and priority is claimed based on this application. This application refers to this application and therefore contains the entire content of this application. [0002] The present invention relates to an elevator rope cleaning tool for cleaning wire ropes. Background technique [0003] In an elevator, wire ropes are used for main ropes and compensating ropes that connect the car and the counterweight. The steel wire rope can be manufactured by twisting thin steel wires called "strands" to form a strand, and twisting a plurality of strands around a fiber core in the center. [0004] Usually, this wire rope is coated with grease for lubrication or rust prevention. However, if the wire rope is used for a long period of time, the grease will harden or dirt will adhere to the grease, which may hinder the operation of the elevator. Therefore, maintenance ...
