Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a disassembly tool for a valve body of a fracturing pump. Background Art

[0002] Existing disassembly tool technology mostly uses knife cutting for disassembly, but this method can only be disassembled by cutting when in use. For example, a Chinese patent discloses "a fracturing pump valve body disassembly tool" with an application number of "CN202320067580.0". When cutting the valve rubber on the valve body, the guide claw of the valve body is first placed upward in the positioning groove, and the valve body is pushed to one end of the positioning groove, and then the sliding seat is pushed toward the valve body, so that the cutting knife cuts the valve rubber on the valve body. However, it can only be disassembled by cutting and reverse movement. Sometimes, only disassembly is required, and replacement is not required, which causes waste and is easy to cause scratches during cutting. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art and provides a fracturing pump valve body disassembly tool, which cooperates with a rotating rod, a support rod, a disassembly pry plate and a first spring. Since the spring is in a contracted state, the limit rod prevents the disassembly pry plates from colliding with each other and causing damage. The disassembly pry plate clamps the valve rubber, and the first spring will shrink and thus be firmly fixed. By rotating the rotating rod, the valve rubber is easily pulled out, which is easy and labor-saving, simple and convenient, and improves the disassembly efficiency. Through the pull rod and the second spring, the upper splint and the lower splint, the upper splint and the lower splint will tightly clamp the disassembly pry plate to prevent the disassembly pry plate from moving and affecting the disassembly quality. When the disassembly pry plate needs to change its position to disassemble valve bodies of different models, it only needs to pull the pull rod to drive the second spring and the upper splint to change the position of the disassembly pry plate, which is simple and convenient.

[0004] The utility model also provides a fracturing pump valve body disassembly tool, comprising: a bottom plate, the upper surface of the bottom plate is fixedly connected to the side plate, the upper surface of the side plate is fixedly connected to the upper plate, the upper plate is provided with a rotating rod, the upper surface of the rotating rod is fixedly connected to the rocking arm, the bottom plate is provided with a slot, and the slot is provided with an upper positioning slot and a lower positioning slot; the lower surface of the rotating rod is fixedly connected to two bases, each of the bases is provided with a support rod, a limiting rod is provided on the support rod, a first spring is provided on the support rod, one end of the first spring is fixedly connected to a force block, the force block is located in the middle of the two support rods, the lower surface of the support rod is fixedly connected to a mounting seat, a disassembly pry plate is provided on the mounting seat, the side surface of the support rod is fixedly connected to a jacket, a pull rod is provided on the top surface of the jacket, the lower surface of the pull rod is fixedly connected to a pull block, the lower surface of the pull block is fixedly connected to a second spring, the other end of the second spring is fixedly connected to an upper clamping plate, the side surface of the jacket is fixedly connected to a lower clamping plate, and the lower clamping plate is located below the upper clamping plate. Through the above device, the disassembly pry plate cooperates with the upper splint and the lower splint, and the disassembly pry plate is embedded in the valve rubber. Due to the elastic force of the first spring, the disassembly pry plate can be free from shaking, so the valve body can be better disassembled. By cooperating with the rotating rod and the rocker, the rocker is rotated, the disassembly pry plate pulls the valve rubber of the valve body, and the valve rubber is directly pulled out, which improves efficiency.

[0005] According to the valve disassembly tool for a fracturing pump described in the utility model, the bottom surface of the bottom plate is fixedly connected with legs, and the number of the legs is four. Through the above device, through the legs, the legs are truncated cone-shaped, so that the legs can be placed on the ground more stably.

[0006] According to the valve disassembly tool for a fracturing pump, the upper surface of the bottom plate is fixedly connected with a rib plate, and the other surface of the rib plate is in contact with the side plate. Through the above device, the rib plate can strengthen the bearing capacity of the side plate to prevent damage caused by long-term use.

[0007] According to the utility model of a fracturing pump valve body disassembly tool, the base and the mounting seat are both provided with a rotating shaft, and the support rod and the disassembly pry plate are driven to rotate by the rotation of the base and the mounting seat. Through the above device, the disassembly pry plate is effectively rotated through the rotating shaft, and the valve bodies of different shapes can be adapted.

[0008] According to the utility model of a fracturing pump valve body disassembly tool, the rotating rod is provided with threads, the upper plate is provided with threaded holes, and the rotating rod is located above the slot 24. Through the above device, the support rod can be rotated through the threads to disassemble the valve rubber on the valve body, and displacement is not easy to occur.

[0009] According to the valve disassembly tool for a fracturing pump, the upper surface of the lower clamping plate fits with the lower surface of the disassembly skid plate, and the lower surface of the upper clamping plate fits with the upper surface of the disassembly skid plate. Through the above device, the disassembly skid plate can be firmly fixed by the cooperation of the upper clamping plate and the lower clamping plate.

[0010] According to the valve disassembly tool for a fracturing pump described in the utility model, there are two limit rods, and the heights of the two limit rods are equal. Through the above device, the limit rods can prevent the two disassembly pry plates from colliding and being damaged, and at the same time, the first spring can be protected from deformation.

[0011] According to the valve disassembly tool for a fracturing pump described in the utility model, a buckle is provided on the jacket, the buckle is connected to the pull rod, and the buckle is located on the upper surface of the jacket. Through the above device, the buckle can effectively control the upper clamping plate and the lower clamping plate to clamp the disassembly pry plate.

[0012] Beneficial Effects

[0013] 1. Compared with the prior art, the valve body disassembly tool for the fracturing pump cooperates with the support rod, the disassembly pry plate and the first spring through the rotating rod. Since the spring is in a contracted state, the limit rod prevents the disassembly pry plates from colliding with each other and causing damage. The disassembly pry plate clamps the valve rubber, and the first spring is tightened to fix it firmly. By turning the rotating rod, the valve rubber is easily pulled out, which is easy and labor-saving, simple and convenient, and improves the disassembly efficiency.

[0014] 2. Compared with the prior art, the valve body disassembly tool for the fracturing pump uses a pull rod and a second spring, an upper clamp and a lower clamp. The upper clamp and the lower clamp will tightly clamp the disassembly pry plate to prevent the disassembly pry plate from moving and affecting the disassembly quality. When the disassembly pry plate needs to change its position to disassemble valve bodies of different models, it only needs to pull the pull rod to drive the second spring and the upper clamp to change the position of the disassembly pry plate, which is simple and convenient.
