Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and more specifically to a piston pump. Background Technology

[0002] Piston pumps are important power components in hydraulic systems. They rely on the reciprocating motion of pistons within a cylinder to change the volume of the sealed working chamber, thereby achieving the oil suction and pressure processes. These pumps have significant advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment, and are therefore widely used in high-pressure, high-flow-rate applications, such as hydraulic presses, construction machinery, and ships. In practical applications of plunger pumps, the reliability and ease of their installation directly impact the overall operational stability and maintenance efficiency. Currently, common plunger pump installation methods often involve direct bolt fastening or connection to the base via flanges. While these traditional methods achieve reliable fixation, they present numerous inconveniences in practice. First, the installation process requires precise hole alignment and the use of tools to tighten multiple bolts individually, a cumbersome and time-consuming process. Second, in situations requiring regular maintenance or replacement of wear parts such as seals, disassembly is equally inconvenient, increasing maintenance time and manpower costs. Furthermore, for equipment with limited space or requiring frequent maintenance, this cumbersome disassembly and assembly process severely impacts work efficiency. Utility Model Content

Detailed Implementation

[0010] A plunger pump includes a plunger pump body 107. Two trapezoidal vertical rods 201 are fixedly connected to the plunger pump body 107. Each trapezoidal vertical rod 201 is slidably connected to an L-shaped rod 101. Each L-shaped rod 101 has two side grooves 104. Each L-shaped rod 101 has two extension plates 401 slidably connected to it. The two extension plates 401 can slide out through the two side grooves 104. Two inverted T-shaped grooves 601 are pre-formed at the installation position of the plunger pump. The two L-shaped rods 101 can be inserted into the two inverted T-shaped grooves 601 respectively. Each inverted T-shaped groove 601 includes a vertical groove 602 and a horizontal groove 603. The width of the horizontal groove 603 is greater than the width of the vertical groove 602. The horizontal groove 603 is located below the vertical groove 602. Each L-shaped rod 101 is provided with a transmission structure that can drive the two extension plates 401 to slide.

[0011] After placing the plunger pump body 107 in the installation position, operate the two L-shaped rods 101 to slide downwards on the two trapezoidal vertical rods 201 respectively, so that the two L-shaped rods 101 are inserted into the two inverted T-shaped grooves 601 respectively. The two L-shaped rods 101 continue to move downwards from the vertical grooves 602 until they reach the lowest position of the inverted T-shaped grooves 601. Then, slide the two extension plates 401 on each L-shaped rod 101 away from each other, so that the two extension plates 401 can enter the range of the transverse groove 603 and contact the left and right sides of the transverse groove 603, thus abutting against the left and right sides of the transverse groove 603. At this time, the two extension plates 401 can also contact the upper and lower sides of the transverse groove 603, thereby achieving a secure fixation of the plunger pump body 107 through the cooperation of the vertical groove 602 and the L-shaped rods 101. The system allows for horizontal insertion and fixing in both front-to-back and left-to-right directions. The extension plate 401, in conjunction with the transverse groove 603, achieves vertical insertion and fixing, ensuring that the plunger pump body 107 can be stably placed in the installation position without the need for cumbersome fixing methods such as screwing in bolts. This enables rapid installation of the plunger pump body 107. Furthermore, when the plunger pump body 107 needs to be disassembled for maintenance, the two extension plates 401 on the single L-shaped rod 101 are slid closer together, and then the L-shaped rod 101 is slid upwards until it is pulled out of the inverted T-shaped groove 601, thus quickly completing the disassembly operation. This simplifies the assembly and disassembly of the plunger pump body 107, making it suitable for applications requiring maintenance or replacement of vulnerable parts such as seals, reducing maintenance costs and manpower burden.

[0012] Each of the trapezoidal vertical rods 201 is fixed with a magnetic plate 202 and a base plate 203. The magnetic plate 202 can attract and fix the L-shaped rod 101.

[0013] When the two L-shaped rods 101 do not need to slide down for fixing, the two L-shaped rods 101 are respectively attached to the two magnetic plates 202 to fix them firmly, which facilitates the subsequent operation of moving the plunger pump body 107. When it is necessary to slide the L-shaped rods 101 down, the staff will manually apply pressure to the two L-shaped rods 101 to make them continue to move down until the two L-shaped rods 101 abut against the two base plates 203. Then, the multiple extension plates 401 are slid to complete the subsequent firm insertion and fixing effect.

[0014] Each L-shaped rod 101 is slidably connected to a movable rod 501. Each L-shaped rod 101 has a slot. The movable rod 501 slides on the L-shaped rod 101 through the slot. Each movable rod 501 is hinged to one end of two hinge rods 402. The other ends of the multiple hinge rods 402 are respectively hinged to multiple extension plates 401.

[0015] When it is necessary to operate multiple extension plates 401 to slide and thus enter the areas where the two transverse slots 603 are located, the two movable rods 501 can be operated to slide down, causing the two movable rods 501 to drive one end of multiple hinge rods 402 to move down. During this process, the other end of the multiple hinge rods 402 will push the multiple extension plates 401 to slide, so that the multiple extension plates 401 slide away from each other, completing the subsequent insertion and fixing effect. That is, the up and down sliding of the two movable rods 501 can drive the multiple extension plates 401 to move horizontally, completing the subsequent insertion effect.

[0016] Each L-shaped rod 101 has two sliding grooves 105, and each movable rod 501 has two sliders fixedly connected to it. The sliders are slidably connected in the multiple sliding grooves 105 respectively.

[0017] The multiple grooves 105 provide additional sliding support for the moving rod 501 in addition to the groove on the L-shaped rod 101, preventing the groove from deforming after long-term use, which would cause the sliding operation of the moving rod 501 to be unstable and thus affect the performance.

[0018] Two baffles 103 are fixedly attached to each of the L-shaped rods 101, and multiple extension plates 401 can contact multiple baffles 103 respectively.

[0019] Multiple baffles 103 can work with L-shaped rods 101 to restrict multiple extension plates 401, so that the multiple extension plates 401 can only move in the horizontal direction, thereby ensuring that when the two moving rods 501 slide down, they can be smoothly transmitted to the two extension plates 401, so that the two extension plates 401 can be smoothly inserted into the two transverse slots 603 to complete the fixation.

[0020] Each L-shaped rod 101 is connected to a sliding sleeve 102, and each sliding sleeve 102 is slidably connected to an auxiliary rod 301.

[0021] After the sliding rod 501 slides down until the contact plate 502 contacts the L-shaped rod 101, the two extension plates 401 are exactly in the position of being fully inserted into the transverse groove 603. Then the auxiliary rod 301 will slide on the sliding sleeve 102, so that the arc block 302 contacts the upper side of the contact plate 502. The auxiliary rod 301 and the L-shaped rod 101 cooperate to fix the sliding contact plate 502, thereby fixing the sliding rod 501, so that the two extension plates 401 are firmly in the position of being inserted into the two transverse grooves 603, thereby further improving the overall insertion and fixing stability of the device.

[0022] Each of the auxiliary rods 301 is fixedly connected to the sliding sleeve 102 with a tension spring.

[0023] When the sliding rod 501 slides down, the auxiliary rod 301 slides on the sliding sleeve 102, causing the auxiliary rod 301 to be misaligned with the contact plate 502. When the contact plate 502 slides to contact the L-shaped rod 101, the tension spring will automatically pull the auxiliary rod 301 back to its original position, so that the auxiliary rod 301 is in the clamping position of the contact plate 502, thereby achieving the effect of strengthening and fixing the sliding rod 501.

[0024] Each of the moving rods 501 is provided with an arc-shaped block 302, and each moving rod 501 has an arc-shaped surface on its lower side.

[0025] The curved surface and curved block 302 enable the auxiliary rod 301 to be automatically pushed and slid on the sliding sleeve 102 by the transmission effect of the curved surface and curved block 302 when the contact plate 502 is moved down to contact the auxiliary rod 301. This causes the auxiliary rod 301 to automatically separate from the contact plate 502. When the contact plate 502 moves to contact the L-shaped rod 101, the auxiliary rod 301 will be pulled by the tension spring and automatically reset to the position that can restrict the contact plate 502, thus achieving the effect of strengthening fixation and bringing convenience to actual operation.

[0026] Each of the L-shaped rods 101 has a rectangular groove 106.

[0027] Under normal circumstances, two cover plates are placed over the two rectangular slots 106 by tightening bolts, thereby sealing the rectangular slots 106. When maintenance or repair of the structure inside the rectangular slots 106 is required, the cover plates are removed by loosening the bolts, thus enabling operation and maintenance and providing convenience for actual use.

[0028] The two sliding sleeves 102 are detachably connected to the two L-shaped rods 101 by bolts.

[0029] When it is necessary to replace the sliding sleeve 102, tension spring, or auxiliary rod 301, the sliding sleeve 102 can be removed from the L-shaped rod 101 by loosening the bolts, and the sliding sleeve 102 can be replaced and maintained.
