AI Technical Summary

Technical Problem

In the prior art, when the hydraulic oil cylinder is disassembled and installed and repaired in the upper cover of the valve body of the clean water valve, the center positioning is not correct, causing the seal ring to be biased to one side, causing oil and water leakage, and it is difficult for human strikes to ensure uniform stress, high labor intensity, frequent maintenance, and high cost.

Method used

A simple disassembly and positioning device for hydraulic oil cylinders with simple structure is designed, including a bracket, a lower fixing frame, an upper fixing frame, a threaded pin and a removable transition rod. Through the combination of the bracket and a fixing frame, the hydraulic oil cylinder is aligned with the center of the upper cover of the valve body of the clean water valve, and uniform pressure is achieved through the threaded pin and the afterburner.

Benefits of technology

The hydraulic cylinder is uniformly disassembled and repaired in the clean water valve, reducing the frequency of water leakage and oil leakage, improving the service life and starting rate of the equipment, and is convenient to operate, low labor intensity and good cost-effectiveness.

Abstract

The utility model belongs to the technical field of conveying equipment, and particularly discloses a simple dismounting and positioning device of a hydraulic oil cylinder for a water isolation ore pulp pump. A support of the device is vertically arranged, two horizontally-extending lower fixing frames are arranged on the lower portion of the support in a left-right symmetrical and suspended mode, an upper fixing frame is fixed to the upper portion, on the same side of the lower fixing frames, of the support, and the distance between the upper fixing frame and the lower fixing frame is larger than the total height of a hydraulic oil cylinder. The threaded ejector rod vertically penetrates through the upper fixing frame in a threaded meshing mode and extends between the two lower fixing frames. The two lower fixing frames in bilateral symmetry are arranged on the lower portion of the support and matched with the threaded ejector rod on the upper portion of the support, so that the hydraulic oil cylinder can be evenly pressed into the upper cover of the valve body of the clean water valve, and the hydraulic oil cylinder can be centered with the center of the upper cover of the valve body of the clean water valve. Therefore, the problems of oil leakage and water leakage caused by the fact that the hydraulic oil cylinder sealing ring deviates to one side after being installed in the valve body upper cover of the clean water valve can be solved. The device has the advantages of simple structure, convenience in operation, low labor intensity and good dismounting and repairing effects.
