Problems solved by technology

This change in center of gravity is due to passive changes during use and cannot be adjusted actively
Or it is to change the configuration of the working condition (such as adding counterweight or changing to the superlift working condition), but this is only a discontinuous, not real-time adjustment of the center of gravity, and the adjustment is not fast enough to reach a stable state

Embodiment Construction

[0033] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully extend the scope of the invention communicated to the technicians.

[0034] like Figure 1-7As shown, the present invention provides an anti-rollover device for a crawler 1-type crane, comprising a crawler 1, a rotating plate 2, a load-bearing platform 3, a main engine 4, a cab 5, a boom 6, a hook rope 7, a hook 8. The luffing wire 9 also includes a counterweight box 10, a piston plate 15, a connecting rod 16 and a telescopic oil cylinder 19. The counterweight box 10 is arranged on the lower side of the end of the bearing platform 3 away from the cab 5, and the over...

Abstract

The invention relates to the technical field of rollover prevention of crawler cranes, in particular to a rollover prevention device and a rollover warning method for crawler cranes. An anti-rollover device for crawler cranes, including crawler belts, rotating discs, load-bearing platforms, main engines, cabs, booms, hook ropes, hooks, luffing wires, as well as counterweight boxes, piston plates, connections Rod and telescopic cylinder. A rollover warning method for a crawler crane, wherein a central control unit can control the telescopic oil cylinder and the air pump to make corresponding actions according to a corresponding degree of alarm, so that the crawler crane has the function of automatic rollover prevention , and such adjustment is real-time and continuous, and the change of the center of gravity of the crawler crane can be visually displayed through the display screen, which improves the operation stability of the operator and improves the anti-rollover performance of the crawler crane.

Description

technical field [0001] The invention relates to the technical field of rollover prevention of crawler cranes, in particular to a rollover prevention device and a rollover warning method for crawler cranes. Background technique [0002] When the traditional crane does not lift the load, the center of gravity is backward, and there is a tendency to tilt backward; when the heavy load or large-span load is lifted, the center of gravity moves forward, and there is a tendency to tilt forward. This change in the center of gravity is due to passive changes in use and cannot be actively adjusted. Either the configuration of the working condition is changed (such as adding counterweight or changing to the super-lifting working condition), but this is just discontinuous, non-real-time center of gravity adjustment, and the adjustment is not fast enough to reach a stable state again. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the prior art, an anti-roll...
