[0002] The wort filter press is a large piece of equipment in the beer saccharification production process. The hydraulic system is an important part of it, providing the necessary pressure for squeezing wort. Due to long-term use or other reasons, the seals of the piston rod in the hydraulic cylinder will wear, resulting in oil leakage inside the cylinder, so that the hydraulic pressure of the wort filter press cannot be kept stable. Therefore, every once in a while, it is necessary to replace the seals of the piston rod in the hydraulic cylinder. Since the length of the hydraulic cylinder of the wort filter press is 3 meters, the weight is 1.5 tons, and the outer diameter is 377 millimeters. If the whole disassembly is adopted, there are a large amount of work and it is not safe (the hydraulic cylinder is 1.5 meters above the ground).

[0003] The wort filter press has filter plates, and there is a problem of insufficient working space for pulling out the piston rod from the front end of the hydraulic cylinder. The current method: use a hand-pulled three-legged hanging bracket (2 tons) and two mobile gantry cranes (2 tons) to disassemble the whole piston rod from the rear end of the cylinder seat of the wort filter press and place it on the working platform, and use a chain block to pull out the piston rod to replace the seal of the piston in the hydraulic cylinder. This method has a large amount of work, and it is necessary to lift and move the hydraulic cylinder frequently; the working site is large, and it is necessary to weld the working platform.
