Hydraulic device for engineering vehicle based on control

Abstract

The invention discloses a hydraulic device based on controlling engineering vehicles, relates to the technical field of engineering vehicles, and solves the problem that the telescopic distance of the legs of the hydraulic support device of the existing engineering vehicles is short, the supporting capacity is poor, and at the same time, each hydraulic support device needs to be adjusted in sequence during use. Adjusting the outriggers and the troublesome operation include the main body of the construction vehicle; a set of drive motors is fixedly connected to the inside of the rear of the main body of the construction vehicle; a set of intermediate transmission shafts are rotatably connected to the rear of the main body of the construction vehicle; the construction vehicle The left and right sides of the main body are rotatably connected with a group of driving screws; the outer side of the secondary swing rod is fixedly connected with a group of supporting hydraulic cylinders. The device has a high folding rate, a relatively large unfolding arm span, and has better support capacity. At the same time, the support points are symmetrically distributed after unfolding, which improves the stability of the support. It is easy to use and can realize rapid unfolding and shrinking. The rod expands to increase the contact area and improve the support capacity.

Description

technical field [0001] The invention relates to the technical field of construction vehicles, in particular to a hydraulic device for controlling construction vehicles. Background technique [0002] In engineering construction, a large number of engineering vehicles are required to complete various construction work. In the use of some engineering vehicles, in order to ensure the stability of engineering vehicles, it is generally necessary to support the body through hydraulic outriggers. [0003] For example, application number: CN201210024571.X The present invention discloses a support device and a construction machinery vehicle. The support device includes: telescopic outriggers, vertical oil cylinders, horizontal oil cylinders, rotating outriggers, rotating outrigger cylinders and swing drive units. The vertical oil cylinder includes a matched vertical piston rod and a vertical cylinder barrel, the vertical oil cylinder is vertically connected to the first end of the tel...
