Description

Technical Field

[0001] The utility model relates to the field of high-pressure pump and valve disassembly, in particular to a high-pressure pump and valve disassembly device. Background Art

[0002] High-pressure pumps are equipment that provide high-pressure power for high-pressure rotary jet cement slurry. They are used for strengthening the foundations of buildings, roads, etc. They can also be used for high-pressure water jets to assist in breaking rocks and dropping coal, supplying fluid to underground hydraulic props, pumping high-pressure water for anchored hydraulic expansion metal anchors, and clearing, dredging, and cleaning large underground pipelines.

[0003] If there are foreign objects on the valve seat of the high-pressure pump and valve, the valve core is deformed and damaged, the inlet and outlet valve springs are stuck or damaged, etc., it is necessary to disassemble and clean the foreign objects or replace the high-pressure pump and valve and other accessories. The high-pressure pump and valve are generally installed between the pump body and the equipment. When disassembling, you need to first remove the bolts on one side. Due to the heavy weight of the high-pressure pump and valve, the weight borne by the other side increases after one side is removed. If the high-pressure pump and valve is not supported during the disassembly process, it is easy to cause the equipment or the valve seat of the high-pressure pump and valve to break, which not only affects the use of the high-pressure pump and valve, but also causes safety hazards. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, since the high-pressure pump valve is heavy, the weight borne by the other side increases after one side is removed. If the high-pressure pump valve is not supported during the dismantling process, it is easy to cause the equipment or the valve seat of the high-pressure pump valve to break, which not only affects the use of the high-pressure pump valve, but also causes safety hazards and other problems. The utility model proposes a high-pressure pump valve disassembly device.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a high-pressure pump valve disassembly device, comprising a shell and a high-pressure pump valve body, a handle fixedly connected to one side of the shell, a reinforcement foot fixedly connected to one side of the shell, a first support rod slidably connected to the inner cavity of the shell, one end of the first support rod fixedly connected to a support assembly, and an interactive support mechanism provided in the inner cavity of the shell;

[0006] The interactive support mechanism includes a transmission gear, an inner cavity of the transmission gear is fixedly connected to a rotating shaft, one end of the rotating shaft is rotatably connected to the inner wall of the shell, one side of the first support rod is fixedly connected to a first tooth block, the inner cavity of the shell is slidably connected to a second support rod, one end of the second support rod is fixedly connected to a support plate, one side of the second support rod is fixedly connected to a second tooth block, and the second tooth block and the first tooth block are both engaged with the teeth of the transmission gear.

[0007] Preferably, the other end of the first support rod is fixedly connected to a first limiting plate, the surface of the first limiting plate is slidably connected to the inner wall of the shell, and an elastic support member is provided on the other side of the first limiting plate.

[0008] Preferably, the elastic support member includes a damping telescopic rod, one end of the damping telescopic rod is fixedly connected to the inner wall of the shell, and the other end of the damping telescopic rod is fixedly connected to one side of the first limit plate. The surface of the damping telescopic rod is provided with a spring, one end of the spring is fixedly connected to the inner wall of the shell, and the other end of the spring is fixedly connected to one side of the first limit plate.

[0009] Preferably, the inner cavity of the first limiting plate is slidably connected to a first guide rod, and one end of the first guide rod is fixedly connected to the inner wall of the shell.

[0010] Preferably, the other end of the second support rod is fixedly connected to a second limiting plate, and the surface of the second limiting plate is slidably connected to the inner wall of the shell.

[0011] Preferably, the inner cavity of the second limiting plate is slidably connected to a second guide rod, and one end of the second guide rod is fixedly connected to the inner wall of the shell.

[0013] The utility model is beneficial in that:

[0014] The utility model uses an interactive supporting mechanism. After both ends of the high-pressure pump valve body are removed at the same time, the overall weight of the high-pressure pump valve body is pressed on the first support rod. The first support rod squeezes the elastic support member downward, and at the same time drives the transmission gear through the first tooth block. The transmission gear rotates on the inner wall of the shell through the rotating shaft. The transmission gear rotates and toggles the second tooth block, so that the second support rod and the first support rod are displaced in the opposite direction. When the pressure on the first support rod drops, the second support rod moves upward to make the support plate fit the surface of the high-pressure pump valve body, achieving auxiliary support, thereby increasing the support effect of the high-pressure pump valve body and ensuring the integrity of the high-pressure pump valve when disassembling. It solves the problem that due to the heavy weight of the high-pressure pump valve, the weight borne by the other side increases after one side is removed. If the high-pressure pump valve is not supported during the disassembly process, it is easy to cause the equipment or the valve seat of the high-pressure pump valve to break, which not only affects the use of the high-pressure pump valve, but also causes safety hazards.

[0024] The interactive support mechanism 5 includes a transmission gear 501, the inner cavity of the transmission gear 501 is fixedly connected to a rotating shaft 502, one end of the rotating shaft 502 is rotatably connected to the inner wall of the shell 1, one side of the first support rod 3 is fixedly connected to a first tooth block 503, the inner cavity of the shell 1 is slidably connected to a second support rod 504, one end of the second support rod 504 is fixedly connected to a supporting plate 505, one side of the second support rod 504 is fixedly connected to a second tooth block 506, the second tooth block 506 and the first tooth block 503 are both engaged with the teeth of the transmission gear 501, the other end of the first support rod 3 is fixedly connected to a first limiting plate 6, the surface of the first limiting plate 6 is slidably connected to the inner wall of the shell 1, and an elastic support member 7 is provided on the other side of the first limiting plate 6. The high-pressure pump valve disassembly device can adopt two groups, and the shell 1 plays the main role of supporting and protecting the internal structure. Component 4 is first fitted with the valve tube of the high-pressure pump valve body 2, and the elastic support component 7, the first support rod 3 and the support assembly 4 support the high-pressure pump valve body 2, so that the high-pressure pump valve body 2 can be removed. After both ends of the high-pressure pump valve body 2 are removed at the same time, the overall weight of the high-pressure pump valve body 2 is pressed on the first support rod 3, and the first support rod 3 squeezes the elastic support component 7 downward, and at the same time drives the transmission gear 501 through the first tooth block 503, and the transmission gear 501 rotates on the inner wall of the shell 1 through the rotating shaft 502.

When the pressure on the first support rod 3 drops, the second support rod 504 moves upward to make the support plate 505 fit the surface of the high-pressure pump valve body 2 for auxiliary support, thereby increasing the support effect on the high-pressure pump valve body 2 and ensuring the integrity of the high-pressure pump valve during disassembly.

Through the elastic support member 7, if the heavy high-pressure pump and valve are disassembled, the weight is directly pressed on the first support rod 3, and the first support rod 3 squeezes the spring 702 downward. The spring 702 can reduce the pressure and try to avoid the first support rod 3 from touching the bottom. In addition, the resilience of the spring 702 can ensure that the first support rod 3 is reset after the high-pressure pump and valve are moved.

[0029] Working principle: The handle 11 is used to facilitate the transportation of the high-pressure pump valve disassembly device to the disassembly site, and the bidirectional screw 402 can be driven to rotate by the adjusting handle 403. The slider 404 and the arc plate 405 are integrally formed, and the slider 404 is respectively threadedly connected to one side of the bidirectional screw 402.
