The invention discloses a hydraulic-electrical integrated power collection system, comprising a rotary joint, a fixed bracket, a sealed bearing chamber, a support shaft, a box body, a low-voltage power-collecting system, a signal transmission power-collecting system, a small bearing chamber, a high-voltage power-collecting system and a junction box , the box is composed of low-voltage power collecting system, signal transmission power collecting system and high-voltage power collecting system from bottom to top, and a small bearing chamber is arranged in the middle of the box. The invention can realize the transmission of high-voltage high-power current, low-voltage high-power current and multiple signal currents, and the transmission of oil and gas, so that the equipment can work normally. High dynamic level, and low temperature resistance, can work normally in the environment of minus 50 ℃. The appearance and structure of this hydraulic-electric integrated power collection system is a hexagonal type, which saves space. The power collection system is a single-piece assembly type, and there is an observation window on the box body, which is convenient for maintenance and replacement of parts, and effectively ensures the power collection system. safety and reliability.
Description
technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a liquid-electric integrated power collection system. Background technique [0002] Electric equipment such as electric excavators, loaders, tower cranes, and electric shovels are widely used in mining, tunnel construction, and chemical companies. The hydraulic-electric integrated power collection system is a kind of electric equipment component that introduces the static current, gas and liquid of the equipment off the vehicle to the dynamic current, gas and liquid of the vehicle on the vehicle. When working, the power is led into the motor through cables and collectors, and the liquid and gas pass through the hydraulic pipe and the pneumatic pipe through the rotary joint to drive the equipment to achieve 360° rotation and work normally. The commonly used current collector structure is as follows: a set of high-voltage ring and brush holder assembly or low-voltage ri...
