This method requires dismantling the entire boom system and placing it on the ground and re-hoisting it back to the crane. Therefore, hoisting equipment with a large tonnage or a large lifting height is required, which occupies a large site, has a long construction period, and poses a greater safety risk. , this conventional method is costly, time-consuming and laborious

The invention provides a method for replacing a hinge support bearing of a crane boom. The method comprises the following steps: 1, mounting a rigid support on the back side of a hinge support, and propping the end part of the boom by using the rigid support to prevent the boom from moving backward; 2, mounting a plurality of lifting lugs, meeting a load requirement, between the boom and a turnplate; 3, mounting a steel wire rope, a first hoist, a second hoist on each lifting lug, and detaching a rotating shaft of the boom; 4, regulating the first hoist and the second hoist to enable the boom to break away from the hinge support and move upwardly along the rigid support as well as expose a bearing of the boom, and repairing and replacing the bearing of the boom; 5, regulating the first hoist and the second hoist to enable the boom to move downwardly along the rigid support back to the hinge support, and mounting the rotating shaft to repair or replace the bearing of the boom. By the method, the fact that large-tonnage hoisting equipment is used for hoisting a crane boom system can be avoided, so that money, time and labor are saved.
Description
technical field [0001] The invention relates to a replacement method for a bearing of a hinge support of a jib frame of a crane. Background technique [0002] At this stage, if there is a problem with the hinge support bearing of the crane jib system and needs to be repaired or replaced, the conventional practice is to disassemble and hang the jib system, then repair and replace the bearing, and then hoist the jib system to the crane. This method requires dismantling the entire boom system and placing it on the ground and re-hoisting it back to the crane. Therefore, hoisting equipment with a large tonnage or a large lifting height is required, which occupies a large site, has a long construction period, and poses a greater safety risk. , this conventional method is expensive, time-consuming and laborious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for replacing the bearing of the jib hinge support ...
