Full-automatic busbar lifting frame hydraulic system capable of effectively reducing return oil back pressure

Abstract

The invention provides a full-automatic busbar lifting frame hydraulic system capable of effectively reducing the return oil back pressure. The full-automatic busbar lifting frame hydraulic system capable of effectively reducing the return oil back pressure comprises a set of motors (1), the set of motors (1) drive a set of double series hydraulic pumps (3) through a set of couplers / bell jars (2),oil suction pipes jointly suck oil from a hydraulic oil tank (7), high-pressure oil passes through a control integrated valve set (10) after passing by a pump control valve set (11), and accordinglydouble-direction rotation of a hydraulic motor (6) is achieved. Rotation and stopping of the hydraulic motor (6) can be achieved through on and off of a two-way electromagnetic valve (10.1) mounted onthe integrated valve set (10) in an inserted mode, and a return oil filter (9) is further arranged in a return oil pipeline of the system. The system is more integrated and intelligentized, the manufacturing cost and the layout space are saved, the problem of high return oil back pressure is solved, and the system is enabled to be simpler and more compact.

Description

(1) Technical field [0001] The invention relates to a fully automatic bus lifting frame hydraulic system, in particular to a bus lifting frame hydraulic system which can effectively reduce oil return back pressure. (2) Background technology [0002] In the busbar lifting frame, the loosening and tightening of the small box clamps is the key operation when lifting the busbar in the electrolytic aluminum industry. The traditional busbar lifting operation is manually operated, and a special wrench is required to complete the loosening of the small box clamps. and tighten. However, manual operation will cause the following problems: ①When manually loosening and tightening the small box clamps, the operator needs to stand on the high-temperature slot cover to operate, which may easily cause personal injury or burn accidents; ②The small box clamps cannot be loosened. In place or insufficient tightening torque, damage to equipment and personal injury; ③Multiple personnel are requi...

AI Technical Summary

Problems solved by technology

However, manual operation will cause the following problems: ①When manually loosening and tightening the small box clamps, the operator needs to stand on the high-temperature slot cover to operate, which may easily cause personal injury or burn accidents; ②The small box clamps cannot be loosened. In place or insufficient tightening torque, damage to equipment and personal injury; ③Multiple personnel are required to cooperate during operation, resulting in low efficiency, high cost, and long operation time; ④Misoperation may easily lead to vicious accidents such as explosions

[0006] In such a hydraulic system, there are mainly the following problems: (1) there is a problem that the torque of the hydraulic torque wrench varies greatly and is not accurate enough, and the torque of tightening or loosening the small box clamp cannot be accurately set or adjusted, Seriously affect the safety in the production process; (2) In addition, there are recoil damage faults to the hydraulic pump at the moment of motor start and stop, and usually there is a difficult problem that the oil return back pressure is too high to cause the hydraulic motor shaft seal to be flushed; (3) In addition, during the start-up process, the traditional system design is not energy-saving and environmentally friendly, and does not conform to the concept of energy-saving and emission reduction, which makes the start-up load of the entire system very large and wastes energy; (4) and with the use of equipment, the cleanliness of the oil will decrease. Gradually decline, causing wear and tear of components, making the whole system unstable; (5) The whole system is not integrated and intelligent enough
