Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology in machine repair workshops, and in particular to a jack pipe press. Background Technology

[0002] A machine repair shop is a place for the maintenance, repair, and modification of mechanical equipment, encompassing tasks such as equipment fault repair, parts replacement, and routine maintenance to ensure the normal operation of machinery. Machine repair shops need hose crimping jacks because pipe repair is a common task in mechanical equipment maintenance. Whether it's repairing damaged hydraulic system pipes or sealing and reducing pipe diameters during connections, the powerful pressure generated by hose crimping jacks is essential for precisely deforming and cutting pipes, improving repair efficiency and quality, and ensuring the sealing and safety of equipment piping systems.

[0003] Most hydraulic pipe presses typically require manual adjustment of the pipe, placing it between multiple press heads. The operator presses the handle to activate the hydraulic pump, which in turn drives the piston, transferring pressure to the press heads. Under this pressure, the press heads squeeze the pipe, causing it to undergo plastic deformation under the constraint of the mold, thus sealing the pipe. This process requires multiple manual adjustments to ensure the pipe is positioned precisely in the center of the press heads, extending the processing time per cycle. Furthermore, the manual operation of pressing the handle to drive the press heads requires continuous manual output, resulting in slow speed and reduced sealing efficiency.

[0004] Therefore, it is necessary to provide a new jack-type pipe clamp to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a jack-type pipe presser.

[0006] This utility model provides a jack-type pipe presser comprising: a receiving plate, a limiting ring, an elastic component, a sliding rod, and a support component. The receiving plate has a groove at its top end, and a control panel is installed on one side of the top end of the receiving plate. A fixing ring is fixedly connected to the bottom interior of the receiving plate. Multiple pressing heads are slidably connected to the top of the fixing ring, and a fixing rod is fixedly connected to the top of each pressing head. A rotating ring is rotatably connected to the top interior of the receiving plate, with a rotating groove in its inner ring and multiple arc-shaped grooves inside. A worm gear is fixedly connected to the outside of the rotating ring. A receiving chamber is formed inside one side of the receiving plate, and a worm gear is rotatably connected to the inner wall of the receiving chamber. A motor is fixedly connected to one corner of the receiving plate. A limiting ring is rotatably connected to the inner wall of the rotating groove, and multiple trapezoidal blocks are fixedly connected to the inner ring of the limiting ring. An elastic component is installed inside each trapezoidal block. Sliding rods are slidably connected to the inner walls of adjacent sides of the multiple trapezoidal blocks, and arc-shaped pressing blocks are fixedly connected to adjacent sides of the multiple sliding rods. A support component is installed at the bottom end of the receiving plate.

[0007] Preferably, the elastic component includes a receiving hole, which is opened inside the trapezoidal block. The receiving hole is provided inside the trapezoidal block and a spring is provided inside the receiving hole. A limiting plate is slidably connected to the inner wall of the receiving hole, and the adjacent side of the plurality of limiting plates is fixedly connected to the distant side of the plurality of sliding rods.

[0008] Preferably, the support assembly includes multiple support legs, the top ends of the multiple support legs are fixedly connected to the bottom end of the receiving plate, and a gasket is fixedly connected to the bottom end of the support legs.

[0009] Preferably, limit blocks are fixedly connected to the opposite sides of the plurality of pressure heads, and the outer side of the fixing rod is slidably connected to the inner side of the arc-shaped groove.

[0010] Preferably, the drive end of the motor is fixedly connected to one end of the worm, and the worm and the worm wheel are meshed together.

[0011] Preferably, the bottom ends of the plurality of trapezoidal blocks are fixedly connected to the top end of the fixing ring.

[0012] Preferably, one end of the spring is fixedly connected to one side of the inner wall of the receiving hole, and the other end of the spring is fixedly connected to the side of the limiting plate away from the sliding rod.

[0013] Compared with related technologies, the hydraulic hose clamp provided by this utility model has the following beneficial effects:

[0014] This invention uses a flexible assembly consisting of a sliding rod, a limiting plate, and a spring to automatically and flexibly clamp and position the pipe through contact with the arc-shaped extrusion block. This ensures that the pipe is accurately positioned in the middle of the pressure head, avoiding the tediousness and errors of manual adjustment and improving the accuracy and efficiency of positioning.

[0015] This invention achieves automated operation by using a motor to drive a worm gear, which in turn drives a rotating ring to rotate, thereby moving the pressure head to compress the pipe. This reduces manpower input and improves the speed and efficiency of pipe pressing operations.

[0016] In this device, the limiting ring remains stable when the rotating ring rotates due to the connection between the trapezoidal block, the fixed ring, and the receiving plate. This does not interfere with the normal rotation of the rotating ring, thus ensuring the stability of the structure and the accuracy of the operation of the entire device.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 A jack-type pipe crimper includes: a receiving plate 1 serving as the basic load-bearing component of the entire jack-type pipe crimper; a groove 2 is provided at the top of the receiving plate 1 to provide suitable space for subsequent pipe crimping operations; a control panel 3 is installed on one side of the top of the receiving plate 1, which integrates multiple function buttons and a display screen; the function buttons are used to control the start and stop of the motor 14 and adjust its speed; the display screen displays the working status of the equipment in real time, facilitating monitoring and adjustment by the operator; a fixing ring 4 is fixedly connected to the bottom of the receiving plate 1; multiple pressure heads 5 are slidably connected to the top of the fixing ring 4; these pressure heads 5 are components that directly contact the pipe and apply pressure, ensuring uniform force when crimping the pipe; limit blocks 6 are fixedly connected to the opposite sides of the multiple pressure heads 5, the function of which is to limit the sliding stroke of the pressure heads 5 and prevent the pressure heads 5 from leaving the guide range of the fixing ring 4 during sliding; and a fixing rod 7 is fixedly connected to the top of the pressure heads 5.

[0025] A rotating ring 8 is rotatably connected to the top of the inner part of the receiving plate 1. The inner ring of the rotating ring 8 has a rotating groove 9, and the inner part of the rotating ring 8 has multiple arc-shaped grooves 10. The curvature and length of the arc-shaped grooves 10 are designed to cooperate with the fixed rod 7 to convert the rotation of the rotating ring 8 into the linear sliding motion of the pressure head 5. The outer part of the fixed rod 7 is slidably connected to the inner part of the arc-shaped grooves 10. A worm gear 11 is fixedly connected to the outer part of the rotating ring 8. A receiving chamber 12 is formed inside one side of the receiving plate 1. A worm 13 is rotatably connected to the inner wall of the receiving chamber 12 to ensure that the worm 13 can be accurately installed and rotate stably. The worm 13 is meshed with the worm gear 11. A motor 14 is fixedly connected inside one corner of the receiving plate 1. The motor 14 provides power to the entire device. A low-noise servo motor is selected. The drive end of the motor 14 is fixedly connected to one end of the worm 13, and the power is stably transmitted to the worm 13 through a coupling.

[0026] The inner wall of the rotating groove 9 is rotatably connected to a limiting ring 15. Multiple trapezoidal blocks 16 are fixedly connected to the inner ring of the limiting ring 15. These trapezoidal blocks 16 are evenly distributed in the inner ring of the limiting ring 15. The bottom ends of the multiple trapezoidal blocks 16 are fixedly connected to the top ends of the fixed ring 4. An elastic component is installed inside the trapezoidal block 16. The elastic component includes a receiving hole 17. The receiving hole 17 is opened inside the trapezoidal block 16. A spring 18 is installed inside the receiving hole 17. A limiting plate 19 is slidably connected to the inner wall of the receiving hole 17. The limiting plate 19 can slide smoothly in the receiving hole 17. The adjacent side of the multiple limiting plates 19 is fixedly connected to the distant side of the multiple sliding rods 20.

[0027] Multiple trapezoidal blocks 16 have sliding rods 20 slidably connected to the inner walls of adjacent sides. One end of the spring 18 is fixedly connected to one side of the inner wall of the receiving hole 17, and the other end of the spring 18 is fixedly connected to the side of the limiting plate 19 away from the sliding rods 20. Multiple sliding rods 20 have arc-shaped extrusion blocks 21 fixedly connected to adjacent sides. The shape of the arc-shaped extrusion blocks 21 is adapted to the shape of the pipe, which can provide stable friction when clamping the pipe, while avoiding damage to the pipe surface.

[0028] A support assembly is installed at the bottom of the receiving plate 1. The support assembly is used to support the entire hydraulic pipe presser and keep it stable during operation. The support assembly includes multiple support legs 22. The top ends of the multiple support legs 22 are fixedly connected to the bottom end of the receiving plate 1. A pad 23 is fixedly connected to the bottom end of the support legs 22. The pad 23 is made of rubber, which can increase the friction with the ground, prevent the equipment from sliding during operation, and also play a role in shock absorption and cushioning.

[0029] The working principle of the hydraulic hose clamp provided by this utility model is as follows:

[0030] The pipe to be processed is placed in the groove 2 for initial positioning. At this time, the pipe is located above multiple pressure heads 5. The pipe will then contact multiple arc-shaped extrusion blocks 21, which will then spread out. This process will cause the sliding rod 20 to drive the limiting plate 19 to slide on the inner wall of the receiving hole 17 and compress the spring 18. After the spring 18 is compressed, it will generate a rebound force to flexibly clamp the pipe, ensuring accurate positioning. After positioning, the pressure parameters required for pipe pressing are set through the control panel 3. At this time, the motor 14 is started. The drive end of the motor 14 drives the worm gear 13 to rotate. Since the worm gear 13 and the worm wheel 11 are meshed, the worm wheel 11 will rotate accordingly. The worm gear 11 is fixedly connected to the rotating ring 8, and the rotating ring 8 also starts to rotate. When the rotating ring 8 rotates, the multiple arc-shaped grooves 10 inside it will interact with the fixed rod 7. Because the top of the fixed rod 7 is fixedly connected to the pressure head 5, the pressure head 5 will move along the sliding direction inside the top of the fixed ring 4. The multiple pressure heads 5 will gradually approach the pipe and squeeze to complete the sealing. During this process, because the limiting ring 15 is rotatably connected to the inner wall of the rotating groove 9, the limiting ring 15 will not rotate with the rotating ring 8 when the rotating ring 8 rotates, because the trapezoidal block 16 is fixedly connected to the fixed ring 4, and the fixed ring 4 is fixedly connected to the bottom of the inner wall of the receiving plate 1. Therefore, it will not affect the rotation of the rotating ring 8.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
