Description

Technical Field

[0002] The plunger pump is an important device in the hydraulic system. It mainly relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump is equipped with a gland to bear the pressure caused by the alternating load in the hydraulic end of the plunger pump and improve the sealing performance of the plunger pump. In particular, some plunger pumps will set a sealing ring in the groove on the outer edge of the gland to further enhance the sealing performance of the gland, but the extrusion deformation of the sealing ring will make the removal of the gland extremely difficult.

[0028] See also Figures 1 to 3 The embodiment of the present application provides a gland disassembly tool, including: a base body 100, having a receiving chamber and a first through hole and a second through hole connected to the receiving chamber, the first through hole and the second through hole being coaxially arranged; a rotating component 200, movably inserted in the receiving chamber through the first through hole, and a connecting hole is provided on the rotating component 200; a connecting component 300, connected to the rotating component 200 through the connecting hole and extending out of the second through hole; and an elastic member 400, arranged between the rotating component 200 and the second through hole.

[0029] In this embodiment, a rotating assembly 200 and an elastic member 400 are additionally provided on the seat body 100, so that the rotating assembly 200 can drive the connecting assembly 300 to rotate, so that the bottom end of the connecting assembly 300 is screwed and locked with the pressure cap pulling hole on the plunger pump pressure cover, thereby realizing the connection and fastening between the connecting assembly 300 and the pressure cover; at the same time, the rotating assembly 200 is rotated to realize its axial downward movement, thereby realizing the compression of the elastic member 400. When the potential energy accumulated in the elastic member 400 can offset or is much greater than the potential energy required for the pressure cover to detach from the valve seat, the rotating assembly 200 is released. At this time, the rotating assembly 200 moves axially upward under the elastic force of the elastic member 400, and drives the connecting assembly 300 connected thereto to move upward, thereby driving the pressure cover connected to the bottom end of the connecting assembly 300 to move upward and pull it out of the valve seat, thereby realizing the removal of the pressure cover. The gland disassembly tool in the present application utilizes the elastic potential energy stored in the elastic member 400 to push the rotating assembly 200 to continue moving, and quickly pulls out the gland, which effectively reduces the labor intensity of the operators and improves the efficiency of gland disassembly; and, compared with the traditional disassembly method of manually hammering the base to pull out the gland, the gland disassembly tool in the present application greatly improves the safety and reliability of the operators during the gland disassembly process.

[0030] Specifically, the pressure cover disassembly tool is configured as a combined component including at least a base body 100, a rotating component 200, a connecting component 300 and an elastic member 400. The base body 100 can be a cylindrical box structure, and a first through hole is provided on the top thereof for the rotating component 200 and the connecting component 300 to be inserted; a second through hole is provided on the bottom thereof for the bottom end of the connecting component 300 to extend out; the radial dimension of the first through hole is larger than or slightly larger than the radial dimension of the second through hole, so that a contact position can be reserved for the bottom end of the elastic member 400 at the periphery of the second through hole to facilitate the assembly of the elastic member 400, and the rotating component 200 and the elastic member 400 can be prevented from escaping from the base body 100 from the second through hole, thereby ensuring the structural integrity of the pressure cover disassembly tool during operation. At the same time, the position of the connecting component 300 can be radially limited to improve the alignment accuracy of the connecting component 300 and the pressure cap pulling hole on the pressure cover. The rotating component 200 can be an I-shaped disc column structure, the bottom end of which passes through the first through hole and is arranged in the accommodating chamber, and is restricted by the first through hole and will not fall out of the first through hole, thereby ensuring the stability and reliability of the rotating component 200 during operation; the top end of the rotating component 200 extends out of the seat body 100, and the operator can realize the overall rotation of the rotating component 200 by rotating the top end, thereby driving the connecting component 300 embedded in the rotating component 200 to rotate, until the bottom end of the rotating component 200 is completely screwed and locked with the pressure cap pulling hole on the pressure cover, the connecting component 300 does not rotate with the rotation of the rotating component 200. At this time, continuing to rotate the rotating component 200 can make the rotating component 200 continue to move downward along its axial direction, and the rotating component 200 is getting closer and closer to the pressure cover. Under the extrusion of the rotating component 200, the elastic member 400 has elastic potential energy that makes the rotating component 200 move upward along its axial direction, and this elastic potential energy can drive the pressure cover to separate from the valve seat. The connecting component 300 can be a rod-shaped component, which is simultaneously inserted into the first through hole and the second through hole of the rotating component 200 and the seat body 100. The top end thereof extends out of the rotating component 200 for the operator to rotate the connecting component 300; the bottom end thereof extends out of the second through hole of the seat body 100 for being inserted into and connected to the pressure cap pulling hole on the pressure cover.

[0031] In one example, the elastic member 400 may be a spring, and a plurality of springs may be provided, and the plurality of springs are spaced and distributed between the second via hole and the rotating assembly 200, so as to increase the elastic potential energy in the system and ensure that the gland can be pulled out smoothly. Of course, in other embodiments, the elastic member 400 may also be a member made of a compressible material to replace the spring, such as rubber, sponge, memory alloy member, etc., which is not limited here.

[0033] In this embodiment, the specific configuration of the rotating assembly 200 is optimized. Specifically, the rotating assembly 200 is configured as a combined component including at least a rotating member 210 and a bearing member 220. The bearing member 220 may include a hollow cylindrical bearing and a spacer ring disposed on the bearing. The outer wall of the bearing is close to the inner wall of the seat body 100, and the inner wall is used to abut the outer wall of the rotating member 210. In this way, the relative rotation of the rotating member 210 and the seat body 100 is realized through the bearing member 220, and the rotating member 210 is moved up and down along its axial direction while rotating. The rotating member 210 can be a rotating disk structure, the bottom end of which can move up and down in the accommodating chamber, but does not deviate from the limitation of the first through hole, and the top end thereof is exposed from the seat body 100 and does not extend into the accommodating chamber. The operator can rotate the top end of the rotating member 210, thereby driving the entire rotating member 210 to rotate around its axial direction and move up and down along its axial direction.

[0035] In this embodiment, the specific configuration of the rotating member 210 is optimized. Specifically, the rotating member 210 is configured as a combined component including at least a limit plate 211, a connecting column 212 and a first handle 213. The limit plate 211 can be a disc-shaped structure with a radial dimension greater than the radial dimension of the first through hole, which is configured in the accommodating cavity and limited by the first through hole. The limit plate 211 is used to abut the top of the elastic member 400; the connecting column 212 is inserted into the first through hole, and the radial dimension of the connecting column 212 is smaller than the radial dimension of the limit plate 211, which is used to provide rigidity to the limit plate 211 and provide an axial installation height to the first handle 213; the first handle 213 can be a cylindrical component, the middle of which is inserted into the installation hole at the top of the connecting column 212 to form a cross-shaped structure, so that the two ends of the first handle 213 can be reserved as the rotation operation ends, which is convenient for the operator to apply force with both hands, reduces the difficulty of applying force for rotation, and improves the user experience.

[0036] In a possible implementation, the base 100 includes a base 110 and a cover 120 , the cover 120 covers the base 110 , the first through hole is disposed on the cover 120 , and the second through hole is disposed on a side of the base 110 away from the cover 120 .

[0037] In this embodiment, the specific configuration of the base 100 is optimized. Specifically, the base 100 is configured as a combined component including at least a base 110 and a cover plate 120. The base 110 may be an open cylindrical box-shaped structure, and a second through hole is provided at the bottom thereof; the cover plate 120 may be an annular plate, and a first through hole is provided at the center thereof; the periphery of the cover plate 120 covers the periphery of the base 110, and the first through hole of the cover plate 120 corresponds to the second through hole of the base 110; the cover plate 120 may be connected to the base 110 by fasteners such as screws / bolts. The outer wall periphery of the bearing member 220 abuts against the inner wall periphery of the base 110, the top end of the bearing member 220 abuts against the cover plate 120, and the bottom end abuts against the inner boss arranged in the base 110; the rotating member 210 is inserted into the first through hole, and its outer peripheral wall abuts against the inner peripheral wall of the bearing member 220, and can move up and down along the axial direction of the bearing member 220; the elastic member 400 is arranged between the bottom of the base 110 and the rotating member 210 to store elastic potential energy in its axial direction; the connecting component 300 is threadedly connected to the connecting hole of the rotating member 210, and passes through the first through hole and the second through hole, and its bottom end extends out of the second through hole.

In this way, an annular groove structure can be formed on the side of the cover plate 120 facing the base 110 by the first convex ring 121 and the second convex ring 122. On the one hand, the annular groove can be used to accommodate the peripheral side walls of the base 110 and the bearing member 220, so as to limit and tighten the base 110 and the bearing member 220 in the radial direction; on the other hand, the limiting plate 211 can be limited by the first convex ring 121, so as to ensure the structural stability and reliability of the entire gland disassembly tooling and extend the service life of the tooling.

[0039] In one example, the radial dimension of the first convex ring 121 is smaller than the radial dimension of the second convex ring 122, the radial dimension of the first through hole is smaller than the radial dimension of the first convex ring 121, the first convex ring 121 can be a continuous annular convex structure, and the second convex ring 122 can be a continuous annular convex structure, so as to facilitate processing and reduce processing difficulty. Of course, in other embodiments, the first convex ring 121 can be an intermittent annular convex structure, and the second convex ring 122 can also be an intermittent annular convex structure, so as to save raw materials.

[0040] In a possible embodiment, the seat body 100 also includes a guide boss 130, which is arranged on a side of the base 110 away from the cover plate 120, and the radial dimension of the guide boss 130 is smaller than the radial dimension of the base 110, and the second through hole penetrates the base 110 and the guide boss 130 at the same time.

[0041] In this embodiment, the specific configuration of the seat body 100 is further optimized. Specifically, the seat body 100 is configured as a composite component including at least a base 110, a cover plate 120 and a guide boss 130.

The guide boss 130 is used to cooperate with the hydraulic end suction chamber / discharge chamber of the plunger pump to achieve a guiding effect between the seat body 100 and the plunger pump, and improve the accuracy of subsequently screwing the bottom end of the connecting assembly 300 into the pressure cap drawing hole on the pressure cap.

[0042] In a possible implementation, the seat body 100 further includes a limiting boss 140 , which is disposed on a side of the base 110 away from the cover plate 120 and is located in the accommodating chamber, and the elastic member 400 is fastened to the base 110 via the limiting boss 140 .

[0043] In this embodiment, the specific configuration of the base 100 is further optimized. Specifically, the base 100 is configured as a composite component including at least a base 110, a cover plate 120 and a limiting convex column 140. The limiting convex column 140 can be a cylindrical protrusion, which is configured at the bottom of the base 110 and extends toward the cover plate 120. At this time, the elastic member 400 can be a spring or a soft rubber elastic body with a socket hole at the bottom, and its bottom can be socketed on the outside of the limiting convex column 140. In this way, the elastic member 400 is prevented from being misaligned with the base 110, so that the connection between the elastic member 400 and the base 110 is stable and reliable, and the elastic member 400 can provide the maximum elastic potential energy in the best state, which is convenient for subsequent removal of the cover.

[0044] In a possible implementation, the seat body 100 further includes a limiting sleeve 150 , which is disposed on a side of the base 110 away from the cover plate 120 and is located in the accommodating chamber, and the elastic member 400 is fastened to the base 110 via the limiting sleeve 150 .

[0045] In this embodiment, the specific configuration of the base 100 is further optimized. Specifically, the base 100 is configured as a composite component including at least a base 110, a cover plate 120 and a limiting sleeve 150.

At this time, the elastic member 400 can be a spring or a compression material member, and its bottom can be embedded in the limiting sleeve 150. In this way, the elastic member 400 is prevented from being misaligned with the base 110, so that the connection between the elastic member 400 and the base 110 is stable and reliable, and the elastic member 400 can provide the maximum elastic potential energy in the best state, which is convenient for subsequent removal of the cover.

[0046] In a possible embodiment, the connecting assembly 300 includes a screw rod 310 and a second handle 320. The screw rod 310 is connected to the rotating assembly 200 through a connecting hole and extends out of the second through hole. The second handle 320 is inserted into the screw rod 310 along the radial direction of the screw rod 310. The second handle 320 is located above the rotating assembly 200.

[0047] In this embodiment, the specific configuration of the connection assembly 300 is optimized. Specifically, the connection assembly 300 is configured as a combined component including at least a screw rod 310 and a second handle 320. The screw rod 310 can be a long columnar component, which is coaxially arranged with the rotating assembly 200 and the seat body 100, so as to ensure that the center of the entire pressure cap removal tool is on a straight line, which is convenient for the subsequent alignment and removal with the pressure cap pulling hole. The second handle 320 can be a cylindrical component, the middle of which is inserted into the mounting hole at the top of the screw rod 310 to form a cross-shaped structure. In this way, the two ends of the second handle 320 can be reserved as rotating operating ends, which is convenient for the operator to apply force with both hands, reduce the difficulty of applying force to pull the cap, and improve the user experience.

[0048] In a possible embodiment, the screw rod 310 includes a first external thread segment and a second external thread segment that are spaced apart. The first external thread segment is threadedly connected to the rotating assembly 200 through a connecting hole. The second external thread segment is located below the first external thread segment and is used to cooperate with the pressure cap pulling hole on the plunger pump pressure cover.

[0049] In this embodiment, the specific configuration of the screw rod 310 is optimized. Specifically, the screw rod 310 is configured as a composite component including at least a first external thread section and a second external thread section. The first external thread section is configured at one end close to the second handle 320, and is used to be threadedly connected with the connection hole on the rotating assembly 200 to enhance the connection and tightness between the screw rod 310 and the rotating assembly 200; the second external thread section is configured at the bottom end of the screw rod 310, and is used to cooperate with the pressure cap drawing hole on the plunger pump pressure cap to achieve the connection and tightness between the screw rod 310 and the pressure cap, so that when the elastic member 400 drives the screw rod 310 to move upward, the pressure cap is driven to move upward together, and is disengaged from the valve seat, so as to achieve the removal of the pressure cap.

[0050] In a specific usage scenario, when the gland disassembly tool provided by the present application is used to disassemble the gland, the guide boss 130 of the seat body 100 is first installed into the hydraulic end suction chamber / discharge chamber of the plunger pump, and the guide boss 130 is used for guidance until the bottom surface of the guide boss 130 abuts against the hydraulic end; then, the second handle 320 is rotated to make the second external thread section at the bottom end of the screw rod 310 completely screwed into the gland pulling hole, completing the connection and tightening of the screw rod 310 and the gland; then, the first handle 213 is rotated, and the connecting column 212 and the limit plate 211 rotate synchronously. At this time, The limiting plate 211 also moves relative to the bearing member 220, making a linear motion downward along its axial direction. The elastic member 400 is squeezed by the limiting plate 211 and begins to store elastic potential energy. When the elastic potential energy stored in the elastic member 400 can offset or is much greater than the potential energy required for the pressure cover to separate from the valve seat, the first handle 213 is released, and the rotating member 210 makes an upward linear motion under the push of the elastic potential energy, while driving the screw rod 310 connected to the rotating member 210 to move upward, thereby driving the pressure plate to move upward, pulling the pressure cover out of the valve seat, and realizing the removal of the pressure cover.
