Auxiliary supporting device of crane and crane with auxiliary supporting device

Abstract

The invention provides an auxiliary supporting device of a crane. The auxiliary supporting device of the crane comprises a support frame, an axle bracket, a support cylinder arranged between the support frame and the axle bracket, a roller and an axle for supporting the roller, wherein the support frame is provided with a fixing device capable of installing the auxiliary supporting device of the crane on the crane, one end of the support cylinder is connected with the support frame, the other end of the support cylinder is connected with the axle bracket, and the axle bracket can move relative to the support frame through the support cylinder and is connected with the support frame in a mode that the axle bracket does not rotate relative to the support frame; the axle is arranged on the axle bracket; and the roller is rotationally arranged on the axle. The invention also provides the crane with the auxiliary supporting device. By adopting the auxiliary supporting device of the crane, the stabilizing plane of the crane can be enlarged, and the tipping resistance of the crane can be improved, so that the safety is ensured when the crane works, particularly when the heavy crane runs at a rotary station.

Description

technical field [0001] The invention relates to the field of heavy machinery, and in particular to a crane auxiliary support device and a crane with the auxiliary support device. Background technique [0002] At present, for lattice jib cranes, especially composite cranes with a lattice jib on board and an all-terrain chassis on off, in order to improve work efficiency, it is often necessary to travel with a jib at a high center of gravity. In this case, due to the high height of the lattice boom, for heavy-duty lattice boom cranes, even if the lattice boom is in the folded state, the height is still high, and because the crane is mostly used on uneven ground such as construction sites, when the crane rotates When the station is driving, it is prone to rollover and cause accidents. [0003] In order to prevent the crane from overturning when it is in operation, especially when it is changing stations, the industry has proposed a side-rollover alarm device, which senses the ...

AI Technical Summary

Problems solved by technology

This auxiliary support device can avoid the occurrence of rollover accidents to a certain extent, but this auxiliary support device must be installed on the outriggers of the crane, and the outriggers of the crane itself will be installed on both sides of the crane, extending outwards. out a certain distance

Like this, the crane with this kind of auxiliary support device must travel with outriggers when changing stations, so it needs a very open site and road surface, and it is still difficult to adapt to the site conditions of general construction sites.
