Problems solved by technology

This change in center of gravity is due to passive changes during use and cannot be adjusted actively
Either change the configuration of the working condition (such as adding counterweight or changing to 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. However, this invention may 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 convey the scope of the invention. communicated to technical staff.

[0034] Such as Figure 1-7As shown, the present invention provides an anti-rollover device for a crawler-type crane, including a crawler belt 1, a rotating disc 2, a load-bearing platform 3, a main engine 4, a cab 5, a lifting wall 6, a hook rope 7, a hook 8. The luffing steel 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 load-bearing platform 3 away from the cab 5. ...

Abstract

The invention relates to the technical field of anti-rollover of crawler cranes, in particular to an anti-rollover device for a crawler crane and a rollover early warning method. The anti-rollover device for the crawler crane comprises a crawler belt, a rotating disc, a bearing table, a main machine, a cab, a lifting wall, a hook rope, a lifting hook and a variable amplitude steel wire, and further comprises a weight box, a piston plate, a connecting rod and a telescopic oil cylinder. According to the rollover early warning method for the crawler crane, a central control unit can control the telescopic oil cylinder and an air pump to perform corresponding actions according to an alarm of a corresponding degree, so that the crawler crane has an automatic rollover prevention function, the adjustment is continuous and in real time, the gravity center change condition of the crawler crane can be visually displayed through a display screen, so that the operation stability of operators is improved, and the rollover prevention performance of the crawler crane is improved.

Description

technical field [0001] The invention relates to the technical field of anti-rollover of crawler cranes, in particular to an anti-rollover device and a rollover early warning method for crawler cranes. Background technique [0002] When the traditional crane is not lifting a load, the center of gravity is at the rear, and there is a tendency to tilt backward; when lifting heavy loads or large-span loads, 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 during use and cannot be adjusted actively. Or it is to change the working condition configuration (such as adding counterweight or changing to superlift working condition), but this is only discontinuous and not real-time adjustment of the center of gravity, and the adjustment is not fast enough to reach the steady state again. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, an anti-rollover...
