Abstract
A fast disassembly mechanism of a side jib for a movable crane consists of a jib, a front supporter of the jib, a short pin roll, a lazy arm and an idler wheel. The front supporter of the jib supports the jib through the idler wheel and the jib is connected with the front supporter of the jib through the short pin roll. The front end of the front supporter of the jib is connected with the laze arm. By adopting the structure, the utility model is convenient to disassemble. The working efficiency is improved about 4 times, the working intensity is reduced about 3 times and the human resources as well as the risk of working high above the ground are reduced.
Description
Technical field
The utility model is a kind of mechanism for assembling-disassembling that is used for the folding auxiliary of large-tonnage wheel crane.
Background technology
The folding auxiliary of large-tonnage wheel crane generally is made up of two joint auxiliarys, weight is heavier, be fixed on principal arm one side, and by three stent support, auxiliary open with removal process in, cause the auxiliary flare easily, the medium-height trestle downwarp, cause front frame major axis plug difficulty, major-minor arm hinge hole to be difficult to align, to open and reclaim dismounting problems such as difficulty, support need re-adjustments, had a strong impact on work efficiency, strengthened labour intensity.
Summary of the invention
The purpose of this utility model provides that a kind of easy accessibility, labour intensity are low, the fast assembly and disassembly mechanism of the movable crane side auxiliary of high efficiency.
The purpose of this utility model is achieved in that by auxiliary, auxiliary front frame, short pin shaft, arm, roller to be formed, and the auxiliary front frame is by the roller wheel bearing auxiliary, and auxiliary connects the auxiliary front frame by short pin shaft, and auxiliary front frame front end connects arm.
Because the utility model adopts said structure, easy accessibility is increased work efficiency about 4 times; Reduce about 3 times of labour intensity; Reduced the risk of human resources and aloft work.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
1 auxiliary, 2 auxiliary front frames, 3 short pin shafts, 4 arms, 5 rollers among the figure.
The specific embodiment
Embodiment: by auxiliary 1, auxiliary front frame 2, short pin shaft 3, arm 4 is formed, auxiliary front frame 2 is by roller 5 supporting auxiliarys 1, to make things convenient for auxiliary 1 on auxiliary front frame 2, to slide, auxiliary 1 connects auxiliary front frame 2 by short pin shaft 2, auxiliary front frame 2 front ends connect arm 4, auxiliary front frame 2 bears auxiliary 1 weight and holds in the palm flat auxiliary 1, reduce auxiliary 1 flare, auxiliary 1 is alignd with the hinge hole of arm 4, plug major-minor arm connects short pin shaft 3 smoothly, the rear end of the position arm 4 of auxiliary front frame 2, can reduce the stressed size of medium-height trestle, can reduce to open when reclaiming auxiliary 1 and the angle of arm 4, thereby reduce the distance of auxiliary 1 center of gravity, thereby the power and the arm of force that reduce medium-height trestle have reduced the suffered moment of flexure of medium-height trestle to principal arm, reduce the medium-height trestle downwarp, eliminate auxiliary 1 flare, be convenient to principal arm, the alignment of auxiliary 1 hinge hole, and easily, plug short pin shaft 3 smoothly.
Claims (1)
1. the fast assembly and disassembly mechanism of a movable crane side auxiliary, form by auxiliary, auxiliary front frame, short pin shaft, arm, roller, it is characterized in that: the auxiliary front frame is by the roller wheel bearing auxiliary, and auxiliary connects the auxiliary front frame by short pin shaft, and auxiliary front frame front end connects arm.
