Problems solved by technology

[0007] Due to the uncertainty and diversity of dismantling and assembly locations of large-tonnage wheeled cranes, sometimes it is difficult to find an auxiliary lifting mechanism, so that it is difficult to separate the boom from the crane turntable, and it is also difficult to install the boom on the turntable, and it is difficult to realize disassembly and assembly. The purpose of assembling large-tonnage wheeled cranes makes it more difficult to operate large-tonnage wheeled cranes

Embodiment 1

[0051] The crane transition assistance device provided in Embodiment 1 includes a carrier frame 130 and a supporting leg 110 for supporting the carrier frame 130 ; the supporting leg 110 includes a hydraulic cylinder 111 and a swing arm 112 . In this example, there are four supporting legs 110 , those skilled in the art can understand that more than three supporting legs 110 arranged in a conventional manner can be provided, and more supporting legs 110 can be provided in order to obtain sufficient bearing capacity.

[0052] The bearing frame 130 is rectangular and forms a bearing surface extending in the horizontal plane. There are two boom brackets 120 on the bearing surface. The two sides of the boom are used to directly contact and support the boom; in this example, the boom bracket 120 forms a concave groove with an upward opening, which cooperates with the side of the boom to prevent the boom from moving in the lateral direction. scroll on w.

Abstract

The invention discloses a crane transition auxiliary device and also relates to a transport trailer with the auxiliary device and a method for dismantling a crane by utilizing the auxiliary device. The crane transition auxiliary device comprises a bearing frame and a supporting leg arranged on the bearing frame, wherein the supporting leg comprises a hydraulic cylinder extending in a vertical direction; and at least two crane jib brackets which are arrayed along the longitudinal direction of a horizontal plane and used for supporting crane jibs are arranged on the bearing frame. When a large-tonnage wheel crane is disassembled and assembled, the separation or the combination of a crane jib and a rotary table can be realized without an auxiliary hoisting mechanism by utilizing the crane transition auxiliary device so as to further conveniently disassemble and assemble the large-tonnage wheel crane. The transport trailer with the auxiliary device can provide convenience for the carrying of the crane jib, and the method for dismantling a crane by utilizing the auxiliary device can provide convenience for transition operations of the large-tonnage wheel crane.

Description

technical field [0001] The present invention relates to a crane transfer technology, in particular to a crane transfer auxiliary device, and also relates to a transport trailer with the crane transfer auxiliary device, and using the crane transfer auxiliary device to assemble and disassemble a crane Crane approach. Background technique [0002] Compared with gantry rail cranes and crawler cranes, the advantages of wheeled cranes are that they are easy to operate in transition, flexible in lifting operations, and can meet the diverse needs of construction operations. At present, the development of large-scale projects has prompted wheeled cranes to continue to develop in the direction of large tonnage and super-large tonnage. At present, large-tonnage wheeled cranes (generally referring to cranes with a tonnage of 300 tons or more) have been widely used in various engineering constructions project. [0003] On the one hand, with the continuous increase of the lifting tonnag...
