CN-121990440-A - Holding device and method for determining rope length

Abstract

The present disclosure provides a holding device and a method for determining a rope length, which can reduce the burden of operators in the operation for determining the rope length of an elevator. The holding device (30) is provided with a fixing device (31) and a mounting device (32). The fixing device (31) has a first connecting piece (33). The mounting device (32) is provided with a mounting member (34) and a second connecting member (35). When the mounting device (32) is moved upward by the hoisting device (12) so as to approach the fixing device (31), the mounting piece (34) is brought into contact with the shackle body (24), and the fixing device (31) is moved downward so as to approach the shackle body (24).

Description

Holding device and method for determining rope length Technical Field The present disclosure relates to a retention device and a method of determining a rope length. Background Patent document 1 describes a rope maintenance device. The maintenance device described in patent document 1 is used to remove a load acting on a rope when, for example, the rope connected to a car of an elevator is replaced or shortened. In the case of using the maintenance device, after the load applied to the rope is removed, an operation for determining the length of the new rope is required when the rope is replaced, and an operation for determining the length of the rope is required when the rope is shortened. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 7-10424 Disclosure of Invention Problems to be solved by the invention Conventionally, in an operation for determining the length of a rope, one operator pulls the rope and a rope shackle for connecting the rope, and other operators mark the rope with a mark for determining the length of the rope. Therefore, there is a problem in that the burden on the operator is large. The present disclosure has been made to solve the above-described problems. An object of the present disclosure is to provide a holding device capable of reducing the burden on an operator in an operation for determining the rope length of an elevator. It is another object of the present disclosure to provide a method of determining a rope length using the holding device. Means for solving the problems The holding device of the present disclosure is a holding device for determining the length of a rope suspending a car of an elevator. The holding device is provided with a fixing device having a first connecting member capable of being fixed to a rope, and an attaching device capable of being attached to a rope shackle to which the rope is connected. The rope shackle includes a rod and a shackle body provided to the rod and connected to the rope. The mounting device includes a mounting member that can be disposed so as to be penetrated by the rod, and a second connecting member that is provided to the mounting member. When the mounting device is moved to one of the upper and lower sides so as to approach the fixing device by the hoisting device coupled to the first coupling member and the second coupling member in a state where the fixing device is fixed to the rope and the mounting device is mounted to the rope shackle, the mounting member contacts the shackle body, whereby the fixing device is moved to the other of the upper and lower sides so as to approach the shackle body. The method of determining the length of the rope of the present disclosure is a method for determining the length of the rope using the above-described holding device. The method includes a fixing step of fixing a fixing device to a rope, a mounting step of mounting the mounting device to a rope shackle so that a rod penetrates through the mounting member, a connecting step of connecting a hoisting device with the first connecting member and the second connecting member, a moving step of moving the fixing device upward or downward by the hoisting device so that the fixing device approaches the mounting device after the connecting step, and a marking step of marking a reference position on the rope after the moving step. Effects of the invention According to the present disclosure, in an operation for determining the rope length of an elevator, the burden on an operator can be reduced.
