Background Technique

[0002] At present, the high-pressure filter at the outlet of the hydraulic pump in the hydraulic station of steel enterprises is downward in direction. When disassembling the filter cartridge, it needs to be disassembled downward. Since the filter cartridge is relatively heavy, two people are required to cooperate to remove the filter cartridge. Moreover, there is a possibility that the filter cartridge may fall and cause injury. At the same time, the working space is small, which seriously affects the working efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an auxiliary replacement device for a high-pressure filter cartridge at the outlet of a hydraulic pump in a hydraulic station, which can complete the disassembly of the high-pressure filter cartridge conveniently and quickly, and can avoid the filter cartridge from falling and causing personal injury during the disassembly process, and solve the problems existing in the background technique.

[0004] The technical solution of the utility model is as follows:

[0005] An auxiliary replacement device for a high-pressure filter cartridge at the outlet of a hydraulic pump in a hydraulic station includes a base, a fixing nut, a support rod, a bolt, a rotating bracket and a locking pin. The fixing nut is located directly above the base, and the fixing nut and the base are connected together by several support rods; the rotating bracket is a cylindrical frame structure matching the high-pressure filter cartridge. A bolt is fixed under the rotating bracket, and the bolt is threadedly connected to the fixing nut. A locking pin matching the high-pressure filter cartridge is provided on the rotating bracket.

[0006] The rotating bracket is a cylindrical frame structure formed by connecting a circular bottom frame and two semi-circular top frames through several connecting rods. The bolt is fixed at the center of the circular bottom frame, and the two semi-circular top frames are connected together by a locking pin.

[0007] There are four connecting rods in total. Each semi-circular top frame is connected to the circular bottom frame by two connecting rods.

[0008] The fixing nut and the base are connected together by three support rods evenly arranged in the circumferential direction.

[0009] The beneficial effect of the utility model is that it can complete the disassembly of the high-pressure filter cartridge conveniently and quickly, and can avoid the filter cartridge from falling and causing personal injury during the disassembly process, reduce the labor intensity of workers, improve the working efficiency, with a simple structure, easy to manufacture and low cost.
