Abstract

The invention provides a buffering system and device for a large concrete batching plant rotary table. The buffering system and the buffering device comprise a hydraulic energy source, a high-pressure oil inlet pipe, a constant displacement motor, an oil return pipe, a constant displacement motor output shaft, an on-off switch magnetic valve, an oil tank, an energy absorber, a non-contact switch and a rotating work table. The hydraulic energy source is communicated with the constant displacement motor through the oil inlet pipe. The constant displacement motor outputs torque to drive the rotating work table to rotate. The rotating work table drives a moving point of the non-contact switch to rotate. Returned oil of the constant displacement motor is communicated with the on-off switch magnetic valve and the oil tank through the oil return pipe for oil return. When the rotating work table drives the moving point of the non-contact switch to rotate to be aligned to a static point of the non-contact switch, an electrical signal is sent out, after the on-off switch magnetic valve is powered on, the on-off switch magnetic valve is located at left end, the on-off switch magnetic valve and the oil tank are disconnected, and the returned oil of the constant displacement motor is communicated with the energy absorber through the oil return pipe for buffering.

Description

technical field [0001] The patent of the present invention relates to the buffer system and device of the turntable of a large concrete mixing plant, especially the buffer system and device of a turntable of a large concrete mixing plant with an energy absorbing device. Background technique [0002] During the operation of the loading and unloading rotary table of the closed large-scale concrete mixing plant, due to the large inertia generated by the large mass of the rotary table, when it stops suddenly, it will produce a large acceleration and a large negative acceleration, resulting in a large impact force. Acceleration is, when time t tends to 0, a tends to infinity. Impact force F=m×a, the mass of m rotary table. Therefore, F is a hard impact, which will cause great damage to the entire slewing system. Contents of the invention [0003] The patent of the present invention provides a buffer system and device for a turntable of a large concrete mixing plant, especiall...
