Abstract

The invention relates to an oil and air hybrid driven lifting control device, which aims to solve the problems of large continuous noise, high energy consumption, oil temperature rise and the like during work of a normal hydraulic system. The oil and air hybrid driven lifting control device mainly comprises a pneumatic hydraulic pump, an oil tank, pneumatic reversing valves, a lifting oil cylinder, a pneumatic position sensor and an electromagnetic reversing valve, wherein an air inlet of the pneumatic hydraulic pump connected with the oil tank is communicated with an air source pipeline; the air source pipeline is connected in series with the electromagnetic reversing valve; a liquid outlet of the pneumatic hydraulic pump is communicated with an oil supply pipeline; the oil supply pipeline is connected in parallel with two pneumatic reversing valves; the two pneumatic reversing valves are connected with the oil tank respectively; the two parallel pneumatic reversing valves are correspondingly connected with the lifting oil cylinder respectively; and two pneumatic detection ports A and B of the lifting oil cylinder are correspondingly connected with a pneumatic position sensor. According to the oil and air hybrid driven lifting control device, a working table is slowly and stably lifted, and air is used as a power source to have the effects of saving energy and reducing consumption.

Description

technical field [0001] The present invention can be used in lifting and lowering of general heavy and large platforms, especially in lifting and lowering of heavy working platforms on large squarers. Background technique [0002] In recent years, new energy sources, especially solar cell technology, have developed rapidly, and the technology and production technology have been greatly improved. The squaring of silicon rods is an important process before the solar cell production line. With the rapid development of the solar industry, the demand for cells is increasing day by day, and the production efficiency of each process of cells is constantly improving. Rod squaring can no longer meet the needs, so a large-scale squaring machine that can cut 25 or even 36 silicon rods at a time came into being. During processing, it is particularly important that the silicon rod cutting platform can be raised and lowered smoothly. The traditional hydraulic lifting control device using ...
