Abstract

The invention discloses a bridge construction device with an optimized control system. The bridge construction device comprises a crane and an engine connected with the crane. The engine is used for driving the crane and comprises a power part, a fuel injection system and a hydraulic part, wherein the hydraulic part comprises a compression cavity, a pump cavity, a return cavity and a hydraulic loop. The compression cavity is located on the rear portion of the engine and provided with a first oil port and a second oil port, and the first oil port and the second oil port are connected with a compression energy accumulator through a first control valve and a second control valve correspondingly; the pump cavity is connected with a low-pressure oil way and a high-pressure oil way through a one-way valve, and the low-pressure oil way is provided with a return control valve and a low-pressure energy accumulator; a pressure reducing valve is arranged on an oil pipeline between a high-pressure energy accumulator and a cylinder body, and a starting valve is arranged on an oil pipeline between the compression energy accumulator and the high-pressure energy accumulator. The bridge construction device is simple in structure, convenient to manufacture, high in scavenging efficiency, stable in performance and large in output torque, and a complete control system and a complete position detecting system are designed.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge construction device with an optimized control system. Background technique [0002] Bridge construction refers to the process of building a bridge according to the design content, mainly referring to bridge construction technology and construction organization, construction management, construction quality, etc. [0003] In the field of bridge construction, bridge construction devices, especially cranes, trucks, and flat cars, are important bridge construction devices. How to further reduce the energy consumption and improve the efficiency of bridge construction devices is a problem that people have been concerned about. Today's cranes are basically driven by engines, but existing engines generally have problems such as overly complex structures, inaccurate control, and insufficient output torque. Therefore, we can improve the performance of bridge construction device...
