Double-energy-accumulator track hydraulic tensioning device, paver and control method
The invention discloses a double-energy-accumulator crawler hydraulic tensioning device, a paver and a control method, the double-energy-accumulator crawler hydraulic tensioning device comprises a crawler assembly, the crawler assembly comprises a crawler, and the double-energy-accumulator crawler hydraulic tensioning device further comprises a hydraulic electric control system and a tensioning oil cylinder connected with the crawler; the hydraulic electric control system comprises a main pump, a pressure reducing valve, control valves, oil ways, pressure sensors, an energy accumulator and a controller, the main pump is connected with the pressure reducing valve, the pressure reducing valve is connected with a second control valve, the second control valve is connected with the two oil ways connected in parallel, and each oil way is provided with a first control valve and a pressure sensor. The first control valve is respectively connected with the two energy accumulators, the tail ends of the oil ways are respectively connected with the tensioning oil cylinder, and the second control valve, the first control valve and the pressure sensor are respectively connected with the controller. The problems that when the paver is in a normal working condition, the tensioning force is too large, so that a caterpillar track is abraded, and when the tensioning force is insufficient in a limiting working condition, the caterpillar track skips are solved.
本发明公开一种双蓄能器履带液压张紧装置、摊铺机及控制方法，包括履带组件，所述履带组件包括履带，还包括液压电控系统及与履带连接的张紧油缸；所述液压电控系统包括主泵、减压阀、控制阀、油路、压力传感器、蓄能器和控制器，所述主泵与减压阀连接，减压阀与控制阀二连接，所述控制阀二与两个并联的油路连接，各油路上均安装有控制阀一和压力传感器，所述控制阀一分别与两个蓄能器连接，各油路的末端分别与所述张紧油缸连接，所述控制阀二、控制阀一和压力传感器分别与所述控制器连接。本发明解决了摊铺机正常工况时张紧力过大导致履带链轨磨损和极限工况时张紧力不足导致履带跳齿的问题。
