Description

Technical Field

[0001] The utility model relates to the technical field of mud pump part disassembly, and particularly relates to a pressing cap disassembly device for a mud pump pump head cylinder sleeve. Background Technique

[0002] A drilling mud pump is a machine used to transport mud or flushing fluids such as water during the drilling process. The mud pump transports the flushing fluid to achieve the purposes of cooling the drill bit, removing the cuttings and transporting them to the surface. This is crucial for keeping the drill hole unobstructed, preventing the drill bit from overheating and improving the drilling efficiency.

[0003] The mud pump cylinder sleeve is an important and easily worn part at the hydraulic end of the mud pump. It mainly plays the roles of protecting the pump body, sealing and guiding the piston movement. The mud pump pressing cap is one of the main accessories at the hydraulic end of the mud pump. It is usually used to press tightly the cylinder sleeve and other sealing components to ensure the normal operation of the mud pump under high pressure.

[0004] Generally, the cylinder sleeve is sleeved on the pump head of the mud pump. Since the mud pump cylinder sleeve and the mud pump pump head are of a split structure, and the mud pump pump head and the cylinder sleeve need to bear high pressure during use, the mud pump cylinder sleeve belongs to a vulnerable part and needs to be frequently replaced during the production process. At the same time, the fit between the cylinder sleeve and the pump head is quite tight, which causes great trouble in replacing the cylinder sleeve. During the replacement process, it is difficult to disassemble, time-consuming, and safety accidents often occur, which has been plaguing each well team. Currently, when each well team replaces the mud pump cylinder sleeve, they generally use a hammer to knock and a crowbar to pry and press the pressing cap to remove the pressing cap, and then disassemble the cylinder sleeve. Sometimes, a crane is also needed for assistance. Such a method sometimes damages the parts of the equipment or causes the parts to be scrapped, and at the same time adds a lot of potential safety hazards to the safety of the workers. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressing cap disassembly device for a mud pump pump head cylinder sleeve to solve the problem that knocking the pressing cap with a hammer and prying the pressing cap with a crowbar will cause damage to the parts.

[0006] To achieve the above purpose, the basic scheme provided by the utility model is: a pressing cap disassembly device for a mud pump pump head cylinder sleeve, including a ratchet wrench. A number of diamond-shaped blocks are fixedly connected to the ratchet teeth of the ratchet wrench. A cylinder sleeve is sleeved on the pump head of the mud pump, and a pressing cap is sleeved on the cylinder sleeve. The pressing cap is threadedly connected to the pump head of the mud pump. A number of convex platforms are fixedly connected to the outer wall of the pressing cap, and each diamond-shaped block corresponds to a convex platform one by one.

[0007] The principle and beneficial effects of the present utility model are as follows: By providing diamond-shaped blocks on the ratchet teeth of the ratchet wrench, the continuous contact between the diamond-shaped blocks and the convex platforms causes the compression cap to continuously rotate outward, so as to remove the compression cap labor-saving and quickly without damaging the parts. The specific operation principle is: When turning the ratchet wrench in the direction of screwing the compression cap outward, the diamond-shaped block contacts the front convex platform and transmits the force to drive the convex platform to drive the compression cap to rotate in the direction of force output. When the angle of the ratchet wrench is adjusted back, the reverse inclined surface of the diamond-shaped block does not contact the convex platform. Repeating the above operation continuously can make the compression cap rotate outward continuously, and finally the compression cap is unscrewed from the pump head by the ratchet wrench.

[0008] Solution two, which is the optimization of the basic solution, further includes a base located on one side of the mud pump. A bracket is fixedly connected to the base. One end of the bracket away from the base is bolted with a hydraulic cylinder. A double pin ear is fixedly connected to the output end of the telescopic rod of the hydraulic cylinder, and the double pin ear is pin-connected with the ratchet wrench. Through the setting of the hydraulic cylinder and the hinge relationship between the double pin ear and the ratchet wrench, it is convenient to convert the horizontal force of the telescopic rod of the hydraulic cylinder into the force that makes the compression cap rotate outward continuously, and it is convenient to realize the disassembly of the compression cap by the continuous telescoping of the telescopic rod of the hydraulic cylinder.

[0009] Solution three, which is the optimization of solution two, a reinforcing rib one is fixedly connected to the base, and the other end of the reinforcing rib one is fixedly connected to the bracket. Through the setting of the reinforcing rib one, it is convenient to further stabilize the supporting relationship between the base and the bracket.

[0010] Solution four, which is the optimization of solution two, a cross bar is fixedly connected to the bracket. One end of the cross bar is fixedly connected with a vertical bar, and one end of the vertical bar is fixedly connected with a support plate, and the support plate is located directly below the hydraulic cylinder. Through the setting of the support plate, it is convenient to support the hydraulic cylinder, improve the operation safety, and share the pressure from the hydraulic cylinder borne by the bracket to a certain extent.

[0011] Solution five, which is the optimization of solution four, a reinforcing rib two is fixedly connected to the connection part of the cross bar and the vertical bar, and the other end of the reinforcing rib two is fixedly connected to the bracket. Through the setting of the reinforcing rib two, it is convenient to further fix the vertical bar and the cross bar on the bracket.

[0012] Solution six, which is the optimization of solution two, a roller with a brake is fixedly connected to the bottom of the base. Through the setting of the roller with a brake, it is convenient to place the base on one side of the mud pump when the compression cap needs to be disassembled, and move the base away when the compression cap does not need to be disassembled.
