The protective plate is placed on the top wall of the mounting cover and is respectively inserted into the slots at the top ends of vertical rod one and vertical rod two on both sides. The height of vertical rod one and vertical rod two is locked by the protective plate.
[0007] Preferred technical solution four: The device frame is equipped with a heavy-duty guide rail, the oil drum is slidably mounted on the heavy-duty guide rail, and the end of the oil injection pipeline is detachably connected to the oil injection nozzle on the oil injection cylinder.
[0008] Preferred technical solution five: The side wall of the mounting cover is provided with a window for the steel wire rope to pass through.
[0009] Preferred technical solution six: The oil injection pipeline includes a return oil pipe, an oil outlet pipe, an oil injection main pipe, a pressure gauge, a three-way valve one, and a three-way valve two. The return oil pipe is located at the top of the oil drum, and the oil outlet pipe is located at the bottom of the oil drum. The return oil pipe is connected to the oil injection main pipe through a branch pipe one, and the oil outlet pipe is connected to the oil injection main pipe through a branch pipe two. A branch pipe three connects the return oil pipe and the oil outlet pipe. The three-way valve one is installed between the return oil pipe and branch pipes one and three, and the three-way valve two is installed between the return oil pipe and branch pipes two and three. The pressure gauge is located on branch pipe two. The oil injection main pipe is quickly connected to the oil injection nozzle on the oil injection cylinder through a quick connector.
[0010] Preferred technical solution seven: A heater is provided inside the frame of the device, and the oil injection main pipe passes through the heater.
[0011] The above structure gives this solution the following advantages:
[0012] 1. The heating and pressurizing oil injection method results in a higher grease penetration rate;
[0013] 2. The oil filling method adopts a circulating oil filling pipeline to ensure that the oil is heated evenly before use;
[0014] 3. After the hydraulic rod is pushed to the bottom, a protective plate is used to strengthen the protection and prevent the pressure inside the oiling cylinder from being too high and opening the mold. Attached Figure Description
