Problems solved by technology

[0002] At present, there are two main ways to automatically turn the outriggers of the crane. The first is to drive the turning of the outriggers by adding an additional cylinder to push the chain or connecting rod. The second is to drive the gears to rotate through the rack oil cylinder, and the gears are fixed on the support. However, although the above two methods at this stage can complete the flipping of the outriggers, they all require additional devices such as hydraulic pipelines, oil cylinders, gears, and operating valves.

Abstract

The invention discloses an automatic turnover device for crane supporting legs, and belongs to the field of supporting leg turnover. The automatic turnover device for the crane supporting leg comprises an installation fixing plate block and a transverse supporting leg which is fixedly installed on the front surface of the fixing plate block. The vertical supporting leg hinged support is fixedly installed on the side face, away from the installation fixing plate, of the transverse supporting leg; the vertical hydraulic cylinders are fixedly arranged on the surfaces of the transverse supporting legs, and telescopic vertical supporting legs are installed at the lower ends of the vertical hydraulic cylinders; wherein the vertical hydraulic cylinder and the vertical supporting leg hinged support are provided with linkage connecting rod mechanisms which are matched with each other, the lower end of each linkage connecting rod mechanism is fixedly connected with a sliding push rod, a guide mechanism is fixedly installed on the surface of the vertical hydraulic cylinder, and a limiting sliding block is fixedly installed on the outer wall, located below the guide mechanism, of the vertical hydraulic cylinder; according to the invention, rapid mechanical recovery can be realized, so that the space can be effectively saved, packaging and transportation are facilitated, and conversely, during unfolding, the device can rapidly extend out and can be put into operation in time.

Description

technical field [0001] The invention relates to the technical field of overturning of outriggers, in particular to an automatic overturning device for outriggers of a crane. Background technique [0002] At present, there are two main ways to automatically turn the outriggers of the crane. The first is to drive the turning of the outriggers by adding an additional cylinder to push the chain or connecting rod. The second is to drive the gears to rotate through the rack oil cylinder, and the gears are fixed on the support. However, although the above two methods at this stage can complete the flipping of the outriggers, they all require additional devices such as hydraulic pipelines, oil cylinders, gears, and operating valves. The structure is complex and the cost is high. There must be a special operating valve or switching valve during operation, the operation is cumbersome, and the additional pipelines and hydraulic components are also likely to cause potential failures.
