Abstract

The invention discloses an electrohydraulic fire truck platform level control device, which comprises an oil tank, a return oil tank, an electromagnetic reversing valve, a proportional servo valve, a proportional servo valve amplifier, a hydraulic cylinder and a control and leveling circuit board, the oil tank is connected with the electromagnetic reversing valve through a first branch, and the electromagnetic reversing valve is connected with one cavity of the hydraulic cylinder through a second branch; the return oil tank is connected with the electromagnetic reversing valve through a third branch, and the electromagnetic reversing valve is then connected with the other cavity of the hydraulic cylinder through a fourth branch. The electrohydraulic fire truck platform level control device, which is an electrohydraulic manned engineering machine platform level control device integrated with level detection, signal processing and amplification, electrohydraulic proportion / servo conversion and the like, improves operability, can prevent shake and impact, and enhances safety and reliability.

Description

technical field [0001] The invention relates to the field of hydraulic engineering machinery, in particular to a horizontal electro-hydraulic control device for a fire truck platform. Background technique [0002] As the main construction machinery, more than 95% of them currently use hydraulic transmission and control technology. Hydraulic transmission and control technology is the basic condition to promote the continuous development of the mainstream direction of construction machinery; under the conditions of narrow installation space and strict restrictions on weight, it can achieve high power and centralized and flexible control of multiple actuators (machine position, remote control, remote control, etc.) ). In the case that the engine can only be used as the driving force, the comprehensive utilization and limitation of power can be achieved. In the relatively harsh field working environment and high oil temperature due to the limitation of the fuel tank volume, th...
