Self-propelled crane for building construction

Abstract

The invention discloses a self-propelled crane for building construction. The structure of the self-propelled crane comprises a sucker support frame, a protective device, a hydraulic rod, an anti-droplifting hook, a tractor, a lifting hoist, a bracket, a lifting support rod, a transmission belt fixing cavity, a crane base, a mounting seat and a vehicle body. When the self-propelled crane is usedafter improvement, a sliding sleeve is extruded and fixed inwards, a lifting hook is tightly embedded and fixedly connected to a tractor through a movable clamping ring, an adjusting piece and a rotating block can swing to adjust the position according to the weight of a material lifted by the lifting hook, a return spring of the lifting hook is protected, the phenomenon that the lifting hook falls off is avoided, after the material is lifted, when the lifted material collides with the vehicle body, an anti-collision plate and an anti-collision cap are used for dispersing collision force colliding with the vehicle body, then a reinforcing rod piece assists a protection ring to work, stress of a protection elastic block is reduced, an anti-collision assembly and the protection elastic blockplay a role in protecting the vehicle body, the crane can work normally, and the working safety of workers is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a self-propelled crane for building construction. Background technique [0002] A self-propelled crane refers to a boom-type crane that has its own power and relies on its own operating mechanism to move along a track or trackless channel. At present, it is widely used in various construction sites due to its flexible transition performance. Most of the boom devices of self-propelled cranes adopt a telescopic structure, and the main structure is formed by nesting multiple boom sections in sequence. During the actual hoisting operation, the boom can be telescopically adjusted according to the needs of different jobs to adjust the working length of the boom. When it comes to hoisting, what needs to be improved: [0003] 1. When hoisting at the construction site, it is often found that the hooks of the lifting equipment are severely deformed, and some return springs fail or ar...

AI Technical Summary

Problems solved by technology

During daily hoisting, it is easy to decouple the sling, causing heavy objects to fall and casualties; when used on the construction site, the positioning accuracy is poor due to the limitation of the crane’s measurement angle. If the hoisted material is too large or too For a long time, the hoisted material will collide with the crane, causing the car body to fail to work normally, affecting the work of the staff, and reducing the working quality of the crane
