AI Technical Summary
In the existing crane control room displacement structure, the connection between the displacement bracket and the control room leads to uneven stress, resulting in unstable swing and tearing of the lugs, and different types of crank arms and channels cannot be freely matched.
A modular lifting control room displacement bracket structure is adopted. Through the L-shaped displacement bracket support plate and rear frame plate design, multiple mounting holes and telescopic cylinders are used to evenly distribute the stress. The height and angle of the rear frame plate can be adjusted to accommodate different types of crank arms and guardrail assemblies.
It avoids the unstable swing and tearing of the lug caused by stress concentration, enhances the strength of the base plate, and realizes the free matching of different types of crank arms and guardrail assemblies, thereby improving commercial applicability.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of crane bodies, in particular to a modular structure of a displacement bracket for a hoisting control room. Background Art
[0002] Crane is a general term for a series of lifting machinery developed for construction areas such as construction sites, factory construction, and bridge construction.
[0003] Currently, the displacement structure of the operator's cab used in crane operations often utilizes lugs and supports extending from the bottom and rear of the cab (which is constructed from welded thin steel plates). These lugs are then moved by hydraulic cylinders. This requires high structural strength to prevent stress concentration during displacement and instability, resulting in swaying and tearing of the lugs. Analysis of the connection between the displacement bracket and the cab reveals the following reasons:
[0004] First, the displacement bracket is welded to the bottom plate of the control room, which causes uneven stress distribution between the bottom plate and the displacement bracket, resulting in swaying and instability during flipping and displacement.
[0005] Second, in the prior art, Figure 1 As shown, the displacement bracket is an L-shaped plate welded and fixed to the bottom plate and rear side plate of the control room. Since the displacement bracket is a thick plate with high strength, while the bottom plate and rear side plate are thin plates with lower strength than the displacement bracket, the rear hanging ear rotation center on the displacement bracket is hinged to the crank arm. When flipping and displacing, the rear hanging ear rotation center is subjected to stress and transfers it to the rear side plate, causing the rear side plate to tear at the position corresponding to the hanging ear rotation center; the stress is also applied to the welding position between the bottom plate and the displacement bracket, causing the bottom plate to tear at the welding position.
[0006] In addition, the displacement bracket of the existing vehicle is welded and fixed to the bottom and rear side of the control cab, so the displacement bracket must be an L-shaped structure. The positional relationship between the first rear hanging ear rotation center on the rear frame plate of the displacement bracket and the second rear hanging ear rotation center at the bottom is fixed. Because the side panel of the displacement bracket is installed with a channel (guardrail assembly), different models of crank arms and channels (guardrail assemblies) can be freely matched. For example: because the position of the rear hanging ear rotation center of the crank arm is too high, the rear end of the channel cannot be arranged. Summary of the Invention
[0007] In response to the above problems, the present invention provides a connection structure that can avoid the phenomenon of unstable swaying and tearing of the lugs and other parts caused by stress concentration in the displacement and flipping control room.
