Description

Technical Field

[0001] The invention relates to the technical field of refrigeration compressor maintenance, and in particular to a refrigeration compressor maintenance platform. Background Art

[0002] Ship refrigeration compressors generally include air conditioning compressors and ice storage refrigeration compressors. A merchant ship has at least 4 refrigeration compressors, and the compressors are mainly piston compressors with less than 8 cylinders, followed by screw compressors. Generally, refrigeration compressors must be hoisted into the workshop for disassembly and assembly due to the small location of the ship.

[0003] The common work sites nowadays are crude, with only cement ground. The compressor workshop must be overhauled by crane to drain the residual oil. Although the ground is protected, the work site will eventually become dirty, with oil marks everywhere and potholes. Construction workers are prone to back pain and injury to leg joints and lumbar vertebrae due to squatting for a long time. Summary of the invention

[0004] The object of the present invention is to provide a refrigeration compressor maintenance platform to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a refrigeration compressor maintenance platform, comprising a placement plate, a residual oil tank is fixedly installed at the bottom of the placement plate, a retaining edge is fixedly installed at the top of the placement plate, a lower oil pipe is arranged at a corner of the top of the placement plate, the bottom end of the lower oil pipe extends into the residual oil tank, an oil drain pipe is connected to the right side of the residual oil tank, the oil drain pipe is close to the bottom of the residual oil tank, a sealing plug is stuck at the right end of the oil drain pipe, and an oil level observation window is fixedly installed on the right outer wall of the residual oil tank.

[0006] Furthermore, support rods are fixedly installed inside the residual oil tank, and the support rods are arranged at the four corners inside the residual oil tank. The support rods are staggered with the lower oil pipe and the oil discharge pipe.

[0007] Furthermore, a filter is fixedly installed inside the lower oil pipe, the placement plate is an inclined plate, and the connection between the placement plate and the lower oil pipe is the lowest point on the upper surface of the placement plate.

[0008] Furthermore, a drawer is provided on the front of the residual oil tank, and the drawer is close to the upper left corner of the residual oil tank.

[0009] Furthermore, a storage bin is fixedly installed on the back side of the residual oil tank, and a hanging ring is fixedly installed on the left outer wall of the residual oil tank.

[0010] Furthermore, the hanging rings are arranged in three groups, and the two hanging rings in each group of hanging rings are distributed up and down.

[0011] Furthermore, a reinforcement frame is provided on the outer wall fixed sleeve of the residual oil tank, and the reinforcement frame is close to the bottom of the residual oil tank.

[0012] Furthermore, an avoidance hole is opened on the outer wall of the reinforcement frame, and the oil drain pipe passes through the avoidance hole.

[0013] Furthermore, the outer wall of the reinforcement frame is rotatably connected to a rotating shaft via a bearing, a seesaw is fixedly installed on the outer wall of the rotating shaft, a fixed plate is fixedly installed on the outer wall of the reinforcement frame, the inner wall of the fixed plate is rotatably connected to a screw rod via a bearing, a lifting plate is threadedly sleeved on the outer wall of the screw rod, the left and right ends of the lifting plate are hinged to one end of the seesaw via a pin, and the end of the seesaw away from the lifting plate is rotatably connected to a wheel via a pin.

[0014] Furthermore, a turning handle is fixedly mounted on the top end of the screw rod, and two groups of the fixing plate and the rotating shaft are provided, and are respectively located on the front and back outer walls of the reinforcement frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The placement board is propped up by the residual oil tank. When the compressor is overhauled, the compressor is placed on the placement board. Because the sum of the heights of the residual oil tank and the floor is 500MM, which is basically level with the knee of a person's calf, workers do not need to squat for a long time during maintenance. The use of retaining edges can prevent the residual oil from flowing from the placement board to the ground. The use of a lower oil pipe can guide the residual oil flowing on the placement board into the residual oil tank to realize the recovery of the residual oil. An oil level observation window is set to observe the residual oil amount in the residual oil tank, and an oil drain pipe is set to discharge the residual oil in the residual oil tank; 2. By rotating the screw rod, the lifting plate moves up, thereby driving the seesaw to rotate, so that the wheels on the seesaw contact the ground, and then the reinforced frame is propped up, so that the residual oil tank is separated from the ground, and the residual oil tank can be pushed to move.
