Description

[Technical Field]

[0001] This utility model belongs to the field of mining machinery technology, specifically relating to a system for separating the bearings of a mining relay pump. [Background Technology]

[0002] A mining relay pump is a submersible pump specifically designed for use in mines. It is assembled from a motor and a centrifugal pump, primarily used for transporting liquids, including water, oil, acids, alkalis, chemicals, suspensions, and liquid metals. Bearings play a crucial role in the operation of a mining relay pump. The bearing primarily supports the shaft, ensuring smooth operation. The inner ring of the bearing mates with the pump shaft, its main function being to fix the pump shaft in a specific position and prevent movement relative to the inner ring. The outer ring of the bearing mates with the housing bore, its main function being to fix the bearing and maintain the clearance between the pump shaft and the housing bore, ensuring stable and reliable bearing rotation.

[0003] During production, bearings need to be disassembled regularly to inspect their wear condition, ensure proper operation, prevent potential problems, and extend equipment lifespan. If bearings are damaged during operation, such as with cracks, wear, or corrosion, they need to be disassembled and replaced to restore normal equipment function. After prolonged operation, the grease in bearings may deteriorate or deplete; disassembling the bearing allows for the addition of new grease to ensure effective lubrication. Regular disassembly and maintenance of bearings can improve overall equipment performance, reduce energy consumption, and increase work efficiency.

[0004] Currently, there is a lack of suitable tools for separating the bearings of relay pumps. Separating the bearings of relay pumps is complicated and inconvenient, and cannot meet production needs. [Utility Model Content]

[0005] The purpose of this invention is to provide a system for separating the bearings of a mining relay pump, so as to solve the problem that the current operation of separating the bearings of relay pumps is complicated and inconvenient.

[0006] The present invention adopts the following technical solution:

[0007] A system for separating the bearings of a mining relay pump, comprising:

[0008] The pump shaft is fixed to the operating platform, which is horizontally set on the ground;

[0009] The movable clamping plate is positioned at the edge of the upper surface of the pump shaft fixing operating table, both front and rear.

[0010] A fixed clamping plate is arranged front to back and opposite to the movable clamping plate, and is fixed on the pump shaft fixing operating table; the fixed clamping plate and the movable clamping plate are used to cooperate to clamp or loosen the pump shaft of the mining relay pump, and the pump shaft of the relay pump extends between the fixed clamping plate and the movable clamping plate in the front-back direction; a first through hole is provided on the fixed clamping plate.

[0011] The push rod runs horizontally to the left and right, with one end rotatably connected to the movable clamping plate and the other end extending to the right through the first through hole. The push rod is used to change the distance between the fixed clamping plate and the movable clamping plate, thereby clamping or releasing the pump shaft of the relay pump. When the pump shaft is clamped, the claw hook of the hydraulic puller grabs the outer ring of the bearing of the relay pump and pulls it backward to completely separate the outer ring of the bearing from the inner ring.

[0012] Furthermore, the pump shaft fixing operating table is provided with a pair of left-right oriented slide rails along its edge; a support block is fixedly connected to the bottom of the movable clamping plate, and a slider is provided on the lower surface of the support block at the corresponding position of the slide rail. The slider is embedded in the slide rail, which facilitates the movable clamping plate to move back and forth.

[0013] Furthermore, it also includes: a fastening cylinder, sleeved on the right end of the push rod and located on the right side of the fixed clamping plate, the left side of the fastening cylinder being fixedly connected to the fixed clamping plate, and its inner cavity being threadedly connected to the push rod. The fastening cylinder is used to screw the push rod in or out, thereby changing the distance between the moving clamping plate and the fixed clamping plate.

[0014] Furthermore, a handle is fixedly connected to the right end of the push rod for rotating the push rod.

[0015] The method of using this utility model is as follows:

[0016] Position the relay pump shaft between the movable clamp and the fixed clamp. Rotate the handle clockwise or counterclockwise to screw the push rod into or out of the inner cavity of the fastening cylinder. The push rod will then translate relative to the fixed clamp, causing the push rod, along with the support block and the movable clamp, to translate along the slide rail, thus moving the movable clamp and the fixed clamp closer or further apart. After the movable clamp and the fixed clamp clamp the relay pump shaft, grab the outer ring of the bearing with the claw hook of the hydraulic puller and pull it backward to completely separate the outer ring of the bearing from the inner ring.

[0017] The beneficial effects of this utility model are:

[0018] This utility model, by setting up a pump shaft fixing operating table, a movable clamping plate, and a fixed clamping plate, can effectively clamp and fix the pump shaft of the relay pump. By placing the pump shaft of the relay pump between the movable clamping plate and the fixed clamping plate, rotating the handle drives the push rod to rotate, thereby realizing the reciprocating translation of the movable clamping plate relative to the fixed clamping plate. After the movable clamping plate and the fixed clamping plate clamp the pump shaft of the relay pump, the claw hook of the hydraulic puller is used to grab the outer ring of the bearing of the relay pump and pull it backward, thereby realizing the complete separation of the outer ring and inner ring of the bearing of the relay pump.

[0019] This utility model is simple in design, easy to operate, and can meet production needs. [Attached Image Description]

The push rod 6 is used to change the distance between the fixed clamping plate 5 and the movable clamping plate 2, thereby clamping or loosening the pump shaft of the relay pump. The right end of the push rod 6 is fixedly connected to a handle 8, which is used to rotate the push rod 6. When the pump shaft is clamped, the claw hook of the hydraulic puller grabs the outer ring of the bearing of the relay pump and pulls it backward to completely separate the outer ring of the bearing from the inner ring.

[0030] The method of using this utility model is as follows: Place the pump shaft of the relay pump between the movable clamping plate 2 and the fixed clamping plate 5, and rotate the handle 8 clockwise or counterclockwise so that the push rod 6 is screwed into or out of the inner cavity of the fastening cylinder 7. The push rod 6 will then translate relative to the fixed clamping plate 5, thereby causing the push rod 6 to move along the slide rail 4 with the support block 3 and the movable clamping plate 2, so as to move the movable clamping plate 2 and the fixed clamping plate 5 closer or further apart. After the movable clamping plate 2 and the fixed clamping plate 5 clamp the pump shaft of the relay pump, the outer ring of the bearing is completely separated from the inner ring of the bearing by grabbing the claw hook of the hydraulic puller and pulling it backward.
