Abstract

The invention discloses a hydraulic supporting control system and an anti-misoperation supporting device. The hydraulic supporting control system comprises a controller, a hydraulic pump, a first hydraulic oil cylinder, a second hydraulic oil cylinder, a first oil cylinder control valve and a second oil cylinder control valve, a distance detection device is arranged on the controller connectively, a normally-open electromagnetic valve is arranged between an oil outlet of the hydraulic pump and a hydraulic oil tank so as to form a hydraulic loop, the first oil cylinder control valve is connected with the first hydraulic oil cylinder so as to control telescoping thereof, the second oil cylinder control valve is connected with the second hydraulic oil cylinder so as to control telescoping thereof, a control end of the normally-open electromagnetic valve is connected with the controller, and an unloading valve is arranged between the first oil cylinder control valve and the first hydraulic oil cylinder. By the means, the hydraulic supporting control system and the anti-misoperation supporting device have the advantage that protecting measures are set for starting and recovery of the first hydraulic oil cylinder, and thereby safety during misoperation is guaranteed.

Description

technical field [0001] The invention relates to the design field of outrigger devices of engineering machinery, in particular to a hydraulic support control system and an anti-misoperation support device. Background technique [0002] Many construction machinery and equipment (such as concrete pump trucks, cranes, fire trucks, etc.) are equipped with supporting legs to ensure the stability and reliability of the work. The action of the outrigger mainly includes unfolding and supporting, and the outrigger needs to be unfolded and supported in place before normal operation. These two actions are respectively controlled by different manual valves or electric control valves. When operating the outriggers, the operator often confuses the operating handles that control the deployment and support. Structural damage to the deployment cylinders, outriggers or support cylinders will result, which will affect the normal operation of the equipment or cause serious accidents. In order ...
