Problems solved by technology

At present, when the steel ropes of bridge cranes are replaced, in most cases, chain cranes and fixed pulleys are used on the monorail crane of the main girder of the factory building to complete the removal and installation of the forehead and the replacement of the old and new ropes. Restricted by the environment: the parking position of the crane must be to align the two drums with the monorail crane and under the main beam, which will stop the production line. Hanging on the main girder with a chain hoist and fixed pulleys, resulting in low work efficiency and great danger, even though safety measures are taken, it is difficult to ensure the personal safety of construction workers

Embodiment Construction

[0016] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] An auxiliary tool and method for replacing a steel wire rope of a bridge crane, comprising the following steps

[0018] 1) A portal frame 1 is made on the upper cover plate 3 of the fixed pulley block 12 of the trolley drum 11 of the bridge crane, and two lifting rings 2 are respectively arranged on both sides of the portal frame 1;

[0019] 2) Hang the chain hoist 4 and the fixed pulley 5 on the suspension ring 2 respectively;

[0020] 2) lock and lift the forehead 6 of the old steel rope with a chain hoist 4, and remove the connecting pin 8 between the forehead 6 and the balance beam 7; this step is to change one side of the old steel rope to a free end;

[0021] 3) One end of the palm rope 9 is connected to the forehead 6, and the other end goes around the fixed pulley 5 and hangs to the ground. The ground staff slowly loosens the palm ...

Abstract

The invention relates to an auxiliary tool and a method for replacing a wire rope of a bridge crane. A gantry frame is manufactured on a cover plate on the upper part of a fixed pulley block of a drum of a bridge crane trolley; lifting rings are arranged on the two sides of the gantry frame; a chain hoist and a fixed pulley are arranged on the lifting rings on the two sides respectively; thus the old wire rope is replaced by a new one. Compared with the prior art, the auxiliary tool and the method have the advantages that: after the device is used, the time for replacing the wire rope is greatly shortened each time, the personal safety of construction personnel is guaranteed, the labor intensity of workers is relieved, the labor productivity is improved, and smooth running of workshop production is guaranteed.

Description

technical field [0001] The invention relates to the field of auxiliary mechanical tools, in particular to an auxiliary tool and method for replacing steel wire ropes of an overhead crane. Background technique [0002] Bridge crane is an indispensable equipment for modern industrial production. It is widely used in lifting, transportation, loading and unloading, installation and other operations of various materials, which greatly reduces the intensity of physical labor and improves labor productivity. work. As a spare part that directly bears the weight, the wire rope should be replaced in time if its wear and tear reaches the scrap standard of the wire rope, otherwise serious personal and equipment accidents will occur. At present, when the steel ropes of bridge cranes are replaced, in most cases, chain cranes and fixed pulleys are used on the monorail crane of the main girder of the factory building to complete the removal and installation of the forehead and the replacem...
