Description

Technical Field

[0001] The present invention relates to the technical field of pipe butt joint, and particularly to an auxiliary device for adjustable socket-type pipe butt joint. Background Art

[0002] Socket pipes are pipes that are connected by direct insertion, and have the advantages of simple connection, good sealing performance, corrosion resistance, and earthquake resistance. They are widely used in the waste water discharge of construction fields, chemical fields, and municipal engineering fields.

[0003] In the actual installation process, socket pipes are divided into two parts: the fixed socket pipes and the insertion pipes to be installed. Before the insertion work, it is necessary to clean and apply oil to the sealing rings of the socket pipes and the insertion surfaces of the insertion pipes. Cleaning is to prevent the dust attached to the sealing rings and the insertion surfaces of the insertion pipes from squeezing the sealing rings during installation, resulting in poor sealing effect of the sealing rings. Applying lubricating oil is to reduce the friction between the insertion pipes and the sealing rings during installation. However, it is difficult to clean the bottom of the insertion pipes close to the ground, and it is difficult to apply lubricating oil. Moreover, the bottom of the insertion pipes is generally lubricated with a brush, which is likely to cause dripping of oil, resulting in waste of lubricating oil. The lubricating oil dripping on the soil will also pollute the environment. Summary of the Invention

[0004] In order to overcome the disadvantages of difficult cleaning and oil application at the bottom of the insertion pipes, the technical problem of the present invention is to provide an auxiliary device for adjustable socket-type pipe butt joint that is convenient for processing the bottom of the insertion pipes.

[0005] An auxiliary device for adjustable socket-type pipe butt joint includes a support frame, on which guiding columns are symmetrically and fixedly connected. It also includes support frames, which are mirror-image arranged on the guiding columns. On the support frames, sliding guide rails are mirror-image distributed and slidably connected. A first sliding groove is formed at the bottom of the sliding guide rails, and sliding rods are slidably connected in the first sliding grooves. Clamping and adjusting units are arranged on the sliding rods. The mirror-image sliding rods are used to drive the clamping and adjusting units to move to clamp the socket pipes and the insertion pipes.

[0006] The clamping and adjusting unit includes a limiting frame, which is slidably connected in the sliding rods. A first elastic member is arranged between the sliding rods and the limiting frames. A rotating guide rail is rotatably connected to the limiting frames, and cleaning and oil application units are arranged on the rotating guide rails. The cleaning and oil application units are used to remove the dust on the pipes and apply lubricating oil.

[0007] Preferably, the cleaning and oiling unit includes a connecting rod base, which is fixedly connected to the rotating guide rail. One end of the connecting rod base at the rear is rotatably connected to a C-shaped connecting rod, and one end of the connecting rod base at the front is rotatably connected to a bent connecting rod. Shells are fixedly connected to both the C-shaped connecting rod and the bent connecting rod. A liquid storage cavity is formed inside the shell, and the liquid storage cavity is filled with hydraulic oil. Springs and strip-shaped hydraulic capsules are fixedly connected to the upper and lower mirror images of the shell, and the strip-shaped hydraulic capsule is adhesively bonded to the spring. The strip-shaped hydraulic capsule is communicated with the liquid storage cavity inside the shell. One end of the spring is fixedly connected to a damping column, and both ends of the damping column are rotatably connected to a moving shell in a damping manner. A cleaning sponge is commonly arranged on the moving shell.

[0008] Preferably, the cleaning and oiling unit further includes a U-shaped frame, which is fixedly connected to the moving shell. One end of the U-shaped frame is rotatably connected to a tapered wheel.

[0009] Preferably, the cleaning and oiling unit further includes a bent connecting rod, which is rotatably connected to the connecting rod base. A sliding plate is slidably connected inside one end of the bent connecting rod. A second elastic member is arranged between the bent connecting rod and the sliding plate. A short connecting rod is rotatably connected to the sliding plate. The short connecting rod at the front is rotatably connected to the bent connecting rod, and the short connecting rod at the rear is rotatably connected to the C-shaped connecting rod.

[0010] Preferably, the cleaning and oiling unit further includes a guiding rod, which is fixedly connected to the sliding rod. A second sliding groove is formed at one end of the guiding rod, and the bent connecting rod slides in the second sliding groove.

[0011] Preferably, the middle part of the guiding rod is of a U-shaped structure and has elasticity.

[0012] Preferably, the clamping and adjusting unit further includes a slider, which is slidably connected to the inner side of one side of the rotating guide rail in a mirror image distribution. Rubber rollers are rotatably connected to one side of the sliders, and third elastic members are arranged between the limiting frame and the rotating guide rail in a mirror image distribution.

[0013] Preferably, the clamping and adjusting unit further includes a bidirectional screw rod, which is rotatably connected to the rotating guide rail in a penetrating manner. The sliders are all threadedly connected to the bidirectional screw rod, and a hand wheel is fixedly connected to the top of the bidirectional screw rod.

[0014] Preferably, a lifting frame is further included, and the adjacent tops of the sliding guide rails are commonly fixedly connected to the lifting frame. A first hydraulic cylinder is fixedly installed on the top of the support frame through an L-shaped frame. A first hydraulic cylinder is fixedly connected to the output shaft of the first hydraulic cylinder, and the first hydraulic cylinder is fixedly connected to the lifting frame.

[0015] Preferably, a first extrusion column is further included. The first extrusion column is fixedly connected to the sliding plate at the front, and a second extrusion column is fixedly connected to the sliding plate at the rear. The first extrusion column cooperates with the second extrusion column. A second hydraulic cylinder is installed on the support frame, and the output end of the second hydraulic cylinder is fixedly connected to the support frame at the front.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By setting a spiral spring and a strip-shaped hydraulic bladder, as hydraulic oil continuously enters the strip-shaped hydraulic bladder, the spiral spring is continuously straightened, and the spiral spring drives the damping column to move. The movement of the damping column drives the cleaning sponge to slide along the wall surface of the pipe through the moving shell. The sliding trajectories of multiple cleaning sponges form a circle, thereby effectively cleaning the dust on the pipe. The dust on the pipe will adhere to the large holes of the cleaning sponge, preventing the dust on the top of the pipe from falling and polluting the bottom of the pipe that has been cleaned, and protecting the pipe from secondary pollution of dust at the connection position due to the cleaning of dust.

[0018] 2. By setting a strip-shaped hydraulic bladder and a spiral spring, as the flow of hydraulic oil inside the strip-shaped hydraulic bladder gradually decreases, the spiral spring starts to wind and reset, and drives the strip-shaped hydraulic bladder to reset. During the reset process of the spiral spring, it drives the damping column to move. The movement of the damping column drives the cleaning sponge to slide and reset along the wall surface of the pipe through the moving shell, enabling the cleaning sponge to absorb the excess lubricating oil flowing out due to extrusion on the wall surface of the pipe, avoiding waste of lubricating oil.

[0019] 3. By setting a hydraulic slide rod and a rotating guide rail, the hydraulic slide rod pushes the limit frame to move synchronously. The movement of the limit frame drives the rotating guide rail to move and drives the rubber rollers to move synchronously. When the upper and lower rubber rollers contact and squeeze the outer wall of the pipe, the rubber rollers are squeezed and drive the rotating guide rail to rotate through the slider. As the hydraulic slide rod moves obliquely downward, the bottom rubber roller generates an upward thrust, and the insertion end of the inserted pipe is squeezed by the rubber rollers and moves upward, so that the center line of the inserted pipe gradually aligns with the receiving pipe, effectively improving the accuracy when the inserted pipe is inserted into the receiving pipe.

Detailed implementation manners

[0030] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the present invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] An auxiliary device for adjustable socket connection of pipes, as Figures 1-5 and Figures 8-9As shown in the figure, it includes a support frame 1, which is composed of multiple square tubes and support columns distributed in a rectangle. Guide columns 2 are symmetrically and fixedly connected to the support frame 1. It also includes a support frame 3. Two support frames 3 are mirror - arranged on the guide columns 2. The support frame 3 located at the front side is slidably connected to the guide column 2, and the support frame 3 located at the rear side is fixedly connected to the guide column 2. Slide rails 4 are mirror - slidably connected to both support frames 3. The slide rail 4 is in an inverted "7" shape. A first chute is opened at the bottom of the slide rail 4. One end of the first chute is connected to an external first hydraulic pump through a first hose. Hydraulic slide rods 5 are slidably connected in the first chute. Clamping and adjusting units 6 are arranged on the hydraulic slide rods 5. The mirror - image hydraulic slide rods 5 are guided by the first chute to drive the clamping and adjusting units 6 to move to clamp and hold the pipe and insert the pipe, and at the same time, when clamping and holding the pipe and inserting the pipe, the center lines of the inserted pipe and the held pipe are aligned to ensure the sealing performance of the connection between the held pipe and the inserted pipe;

[0033] The clamping and adjusting unit 6 includes a limit frame 601. The limit frame 601 is slidably connected in the hydraulic slide rod 5. A first elastic member is arranged between the hydraulic slide rod 5 and the limit frame 601. A rotating guide rail 602 is rotatably connected to the limit frame 601. The connection position between the limit frame 601 and the rotating guide rail 602 is located on the lower side of the rotating guide rail 602, so that when the rotating guide rail 602 is horizontally stressed, it is easy to generate torque due to different upper and lower lengths, which is convenient for the rotating guide rail 602 to rotate along the outer wall of the pipe to clamp and hold the pipe and the inserted pipe. Cleaning and oiling units 7 are arranged on the rotating guide rails 602. When the cleaning and oiling units 7 move, they are used to remove the dust on the held pipe and the inserted pipe and apply lubricating oil to ensure the sealing effect when the held pipe and the inserted pipe are inserted;

[0034] The cleaning and oiling unit 7 includes a connecting rod base 701. The connecting rod bases 701 are fixedly connected to the rotating guide rails 602. One end of the connecting rod base 701 at the rear is rotatably connected to a C-shaped connecting rod 702, and one end of the connecting rod base 701 at the front is rotatably connected to a bent connecting rod 7021. Shells 703 are fixedly connected to both the C-shaped connecting rod 702 and the bent connecting rod 7021. A liquid storage cavity is formed inside the shell 703, and the liquid storage cavity is filled with hydraulic oil. The liquid storage cavity is communicated with an external second hydraulic pump through a second hose. Spring coils 704 and strip-shaped hydraulic bladders 705 are fixedly connected to the upper and lower mirror images of the shell 703, and the strip-shaped hydraulic bladder 705 is adhesively bonded to the spring coil 704. The strip-shaped hydraulic bladder 705 is communicated with the liquid storage cavity inside the shell 703. When there is no hydraulic oil in the strip-shaped hydraulic bladder 705, the strip-shaped hydraulic bladder 705 winds along the winding direction of the spring coil 704. When the strip-shaped hydraulic bladder 705 is filled with hydraulic oil, the strip-shaped hydraulic bladder 705 overcomes the elastic force of the spring coil 704 to straighten the spring coil 704. One end of the spring coil 704 is fixedly connected to a damping column 706. Damping-type rotational connections are provided between the two ends of the damping column 706 and the moving shells 707 in a mirror image distribution. The damping method between the damping column 706 and the moving shells 707 is frictional damping to prevent the moving shells 707 from rotating randomly on the damping column 706. Cleaning sponges 708 are fixedly connected to the two moving shells 707. The cleaning sponge 708 is composed of a wavy dust-removing sponge with thick holes and an arc-shaped oil-absorbing sponge with fine holes adhesively bonded together. The dust-removing sponge has a relatively hard texture and can wipe off the dust on the sealing ring and the insertion surface of the insertion pipe. The arc-shaped oil-absorbing sponge has a relatively soft texture and can apply lubricating oil to the insertion surface of the sealing ring and the insertion pipe, thereby improving the insertion efficiency when the insertion pipe is inserted into the sealing ring.

[0035] As Figure 4 and Figure 7 shown, the cleaning and oiling unit 6 further includes a U-shaped frame 709. The U-shaped frame 709 is fixedly connected to the moving shell 707. One end of the U-shaped frame 709 is rotatably connected to a conical wheel 710. The circumferential outer wall of the conical wheel 710 is a flexible outer wall, enabling the conical wheel 710 to adapt to receiving pipes and insertion pipes of different thicknesses. The conical wheel 710 at the front can contact the inner wall of the insertion pipe, and the conical wheel 710 at the rear can contact the outer wall of the receiving pipe. When the device is working, the insertion pipe and the receiving pipe are located between the cleaning sponge 708 and the conical wheel 710, so that the shell 703 can drive the cleaning sponge 708 to always contact the receiving pipe and the insertion pipe.

[0036] As Figures 1-3 and Figures 6-7As shown, the cleaning and oiling unit 7 further includes a bent connecting rod 711. The bent connecting rod 711 is rotatably connected to the connecting rod base 701. A sliding plate 712 is slidably connected inside one end of the bent connecting rod 711. A second elastic member is provided between the bent connecting rod 711 and the sliding plate 712. A short connecting rod 713 is rotatably connected to the sliding plate 712. The short connecting rod 713 located at the front side is rotatably connected to the bent connecting rod 7021, and the short connecting rod 713 located at the rear side is rotatably connected to the C-shaped connecting rod 702. The second elastic member can absorb the excess pressure of the receiving pipe and the inserted pipe on the cleaning sponge 708 when the cleaning sponge 708 contacts and inserts the pipes, so that the cleaning sponge 708 can adapt to receiving pipes and inserted pipes of different thicknesses.

[0037] As Figure 3 and Figure 7 As shown, the cleaning and oiling unit 7 further includes a guiding rod 714. Guiding rods 714 are fixedly connected to the hydraulic sliding rods 5. The middle part of the guiding rod 714 is of an elastic U-shaped structure. A second sliding groove is provided at one end of the guiding rod 714. The bent connecting rod 711 slides in the second sliding groove. When the rotating guide rail 602 drives the connecting rod base 701 to rotate, the middle U-shaped structure of the guiding rod 714 bends, so that the guiding rod 714 can adapt to the rotation angle between the connecting rod base 701 and the bent connecting rod 711.

[0038] As Figure 6 As shown, the clamping and adjusting unit 6 further includes sliders 603. The sliders 603 are slidably connected in a mirror image distribution inside one side of the rotating guide rail 602. Rubber rollers 604 are rotatably connected to one side of each slider 603. The rubber rollers 604 can prevent the device from scratching the receiving pipe and the inserted pipe when clamping them. Third elastic members are provided in a mirror image distribution between the limit frame 601 and the rotating guide rail 602.

[0039] As Figure 6 As shown, the clamping and adjusting unit 6 further includes a bidirectional lead screw 605. The bidirectional lead screw 605 is rotatably connected through the rotating guide rail 602. The sliders 603 are all threadedly connected to the bidirectional lead screw 605, so that when the bidirectional lead screw 605 moves, the position between the upper and lower two sliders 603 is adjusted to adapt to receiving pipes and inserted pipes of different sizes. A hand wheel 606 is fixedly connected to the top of the bidirectional lead screw 605.

[0040] As Figure 2 As shown, it further includes a lifting frame 8. The adjacent tops of the sliding guide rails 4 are all fixedly connected with the lifting frame 8. The first hydraulic cylinder 9 is fixedly installed on the top of the support frame 3 through an L-shaped frame. The output shaft of the first hydraulic cylinder 9 is fixedly connected to the lifting frame 8. When the first hydraulic cylinder 9 moves, its output shaft drives the lifting frame 8 to move synchronously, so that the lifting frame 8 controls the heights of the sliding guide rail 4 and the hydraulic sliding rod 5, so that the clamping and adjusting unit 6 and the cleaning and oiling unit 7 can adapt to the height of the fixed receiving pipe.

[0041] As Figures 1-3 , Figure 7 and Figure 9 shown, it further includes a first extrusion post 10. A first extrusion post 10 is fixedly connected to the front sliding plate 712, and a second extrusion post 11 is fixedly connected to the rear sliding plate 712. The first extrusion post 10 cooperates with the second extrusion post 11. The first extrusion post 10 and the second extrusion post 11 can contact each other when receiving the pipe, so as to adjust the cleaning and oiling unit 7, so that the cleaning and oiling unit 7 does not contact the pipe when receiving the pipe. A second hydraulic cylinder 12 is installed on the support frame 1, and the output end of the second hydraulic cylinder 12 is fixedly connected to the front support frame 3.

[0042] The working principle is as follows: Before the device works, the staff needs to adjust the height of the clamping adjustment unit 6 based on the fixed height of the received pipe, so that the device can adapt to the received pipes fixed at different heights. The staff starts the first hydraulic cylinder 9, and the movement of the output shaft of the first hydraulic cylinder 9 drives the lifting frame 8 to move up and down. The up and down movement of the lifting frame 8 drives the hydraulic slide rod 5 to move synchronously through the sliding guide rail 4, so that the hydraulic slide rod 5 drives the clamping adjustment unit 6 and the cleaning and oiling unit 7 to move and adjust the height, so that the midpoint position between the upper and lower rubber rollers 604 in the clamping adjustment unit 6 is at the same height as the center line of the pipe, so that the device can adapt to the received pipes fixed at different heights.

[0043] After completing the height adjustment, the staff also needs to adjust the distance between the upper and lower rubber rollers 604 based on the diameter of the pipe, to prevent the pipe from being too small and causing the rubber rollers 604 to be unable to clamp and center the pipe. The staff rotates the handwheel 606, and the rotation of the handwheel 606 drives the bidirectional lead screw 605 to rotate synchronously. The rotation of the bidirectional lead screw 605 makes the two sliders 603 approach each other, and the approach of the two sliders 603 drives the upper and lower rubber rollers 604 to approach each other, so that the clamping adjustment unit 6 can stably clamp pipes of different sizes.

[0044] After the distance between the rubber rollers 604 is adjusted, the device can clamp, center and plug the pipe. At this time, the first hydraulic pump outside is started, so that the hydraulic oil in the first hydraulic pump enters the first slide groove of the sliding guide rail 4 through the first hose, so that the hydraulic oil in the first slide groove pushes the hydraulic slide rod 5 to move, so that the hydraulic slide rod 5 pushes the limit frame 601 to move synchronously, and the movement of the limit frame 601 drives the rotating guide rail 602 to move. When the rotating guide rail 602 moves, it drives the rubber roller 604 to move synchronously through the slider 603, and drives the connecting rod base 701 to move synchronously, so that the connecting rod base 701 drives the C-type connecting rod 702 and the bending connecting rod 7021 to move synchronously, so that the C-type connecting rod 702 and the bent connecting rod 7021 drive the cleaning oiling unit 7 to approach the pipe. At this time, the movement of the hydraulic slide bar 5 will also drive the guide rod 714 to move synchronously. When the upper and lower rubber rollers 604 contact and squeeze the outer wall of the pipe, the rubber roller 604 is squeezed and drives the rotating guide rail 602 to rotate through the slider 603. As the hydraulic slide bar 5 tilts downward, since the rotation connection position of the limit frame 601 and the rotating guide rail 602 is biased towards the bottom of the rotating guide rail 602, the rotating guide rail 602 drives the rubber roller 604 to clamp the pipe through the slider 603, and the angle at which the rubber roller 604 clamps the pipe also changes accordingly. When the rubber roller 604 clamps the plugged pipe, the rubber roller 604 at the bottom squeezes the plugged pipe. The bottom of the lifting frame 8 is provided with a rubber roller 604, so that the plug-in pipe is pushed upward by the rubber roller 604, and the plug-in end of the plug-in pipe is squeezed and moved upward by the rubber roller 604, so that the center line of the plug-in pipe is gradually aligned with the receiving pipe, until the rotating guide rail 602 contacts the top of the limit frame 601. It is worth noting that after the height of the lifting frame 8 is adjusted, the top rubber roller 604 is located above the center line of the pipe. As the rubber roller 604 squeezes the pipe, the top rubber roller 604 limits the upward movement of the pipe, so that the pipe remains stationary after being clamped. Since the clamping adjustment unit 6 of the device is a symmetrical structure, the clamping adjustment unit 6 will simultaneously move along the horizontal direction when clamping the pipe. The centering process of the pipe is realized, thereby improving the accuracy of the plug-in pipe when inserting the receiving pipe, and facilitating the subsequent socket connection between the plug-in pipe and the receiving pipe. During the rotation of the rotating guide rail 602, the rotating guide rail 602 drives the bending connecting rod 711 to rotate through the connecting rod base 701, so that the bending connecting rod 711 drives the guide rod 714 to bend, thereby causing the U-shaped structure of the guide rod 714 to bend adaptively. At this time, the rotating guide rail 602 no longer moves, so that the limit frame 601 remains stationary synchronously, and the hydraulic slide rod 5 continues to move to squeeze the first elastic member so that the first elastic member is compressed. At the same time, the hydraulic slide rod 5 drives the guide rod 714 to move. It is worth noting that in the initial state (with the attached Figure 7For example, the rear bent link 711 is located at the rear end of the second chute of the guide rod 714, and the front bent link 711 is located at the front end of the second chute of the guide rod 714. At this time, the guide rod 714 will squeeze the bent link 711 to move through the second chute, causing the rear bent link 711 to slide from the rear end of the second chute to the front end, and the front bent link 711 to slide from the front end of the second chute to the rear end. Furthermore, the bent link 711 drives the sliding plate 712 to rotate synchronously, and the sliding plate 712 drives the C-shaped link 702 and the bent link 7021 to rotate synchronously through the short link 713. The rotation of the C-shaped link 702 drives the cleaning and oiling unit 7 to fit against the circumferential inner wall of the receiving pipe, and the rotation of the bent link 7021 drives the cleaning and oiling unit 7 to fit against the circumferential outer wall of the inserted pipe, thus facilitating the cleaning and oiling unit 7 to clean and apply lubricating oil to the receiving pipe and the inserted pipe; when the cleaning and oiling unit 7 has contacted the receiving pipe and the inserted pipe, the C-shaped link 702 and the bent link 7021 will not continue to rotate. At this time, the bent link 711 continues to move to compress the second elastic member and drives the sliding plate 712 to continue to rotate, so that the sliding plate 712 drives the short link 713 to continue to rotate, and the C-shaped link 702 and the bent link 7021 remain stationary, enabling the cleaning and oiling unit 7 to adapt to pipes of different thicknesses when contacting the receiving pipe, improving the adaptability of the device to pipes of different thicknesses.

[0045] With the rotation of the C-shaped connecting rod 702 and the bent connecting rod 7021, the outer shell 703 drives the damping column 706 to move through the coil spring 704 and the strip-shaped hydraulic bladder 705, so that the damping column 706 drives the cleaning sponge 708 to move through the moving shell 707. When the moving shell 707 and the cleaning sponge 708 complete the movement, they will contact the pipe, so that the cleaning sponge 708 on the front side contacts the circumferential outer wall of the inserted pipe, and the cleaning sponge 708 on the rear side contacts the circumferential inner wall of the receiving pipe. Moreover, the movement of the moving shell 707 will drive the U-shaped frame 709 to move synchronously, so that the U-shaped frame 709 drives the conical wheel 710 to contact the pipe synchronously. Among them, the pipe is located between the conical wheel 710 and the cleaning sponge 708, so that the conical wheel 710 limits the movement of the moving shell 707 and the cleaning sponge 708 through the U-shaped frame 709, thereby hindering the rotation of the moving shell 707 on the damping column 706, so that the cleaning sponge 708 can only move in an arc along the annular end face of the pipe. Subsequently, the staff starts the external second hydraulic pump, so that the hydraulic oil of the second hydraulic pump enters the liquid storage cavity of the outer shell 703 through the second hose. As the hydraulic oil enters the liquid storage cavity, the hydraulic oil enters the strip-shaped hydraulic bladder 705 through the liquid storage cavity, so that the strip-shaped hydraulic bladder 705 drives the coil spring 704 to gradually straighten. The coil spring 704 extends along the inner and outer diameters of the receiving pipe and the inserted pipe, so that the gradually straightened coil spring 704 drives the moving shell 707 to move through the damping column 706, so that the moving shell 707 drives the conical wheel 710 to roll on the cylindrical surface of the pipe through the U-shaped frame 709. At the same time, the moving shell 707 drives the cleaning sponge 708 to slide on the pipe. The wavy dust-removing sponge of the cleaning sponge 708 cleans the dust on the pipe during the sliding process and adsorbs the dust in its own thick holes, thereby preventing the dust on the top of the pipe from falling and polluting the bottom of the pipe that has been cleaned, and protecting the pipe from causing secondary dust pollution at the connection position due to the cleaning of the dust. Since the strip-shaped hydraulic bladder 705 and the coil spring 704 are in a gradually straightened state, when the strip-shaped hydraulic bladder 705 and the coil spring 704 control the moving shell 707 to drive the cleaning sponge 708 to move through the damping column 706, the strip-shaped hydraulic bladder 705 and the coil spring 704 will generate pressure on the damping column 706, so that the damping column 706 squeezes the cleaning sponge 708 through the moving shell 707, so that the lubricating oil in the cleaning sponge 708 is squeezed out until the mirror-distributed cleaning sponges 708 contact respectively at the top and bottom of the pipe. At this time, the cleaning sponges 708 on the left and right sides have moved half a circumference on the pipe respectively, so that the trajectory of the cleaning sponge 708 on the front side on the circumferential outer wall of the inserted pipe forms a complete circumference, and the trajectory of the cleaning sponge 708 on the rear side on the circumferential inner wall of the receiving pipe forms a complete circumference. The circumferential inner wall of the receiving pipe and the circumferential outer wall of the inserted pipe are both cleaned and oiled by the cleaning sponge 708. The simultaneous cleaning and oiling of the cleaning sponge 708 improves the insertion efficiency of the inserted pipe when inserting the sealing ring.

[0046] After cleaning and greasing the circumferential inner wall of the receiving pipe and the circumferential outer wall of the inserted pipe, the staff needs to reset the cleaning and greasing unit 7 to prevent the cleaning and greasing unit 7 from interfering with the insertion of the receiving pipe and the inserted pipe. The staff adjusts the external second hydraulic pump to start pumping hydraulic oil, so that the liquid storage cavity of the housing 703 is pumped to the second hydraulic pump through the second hose. The hydraulic oil inside the strip-shaped hydraulic bladder 705 enters the liquid storage cavity of the housing 703. As the hydraulic oil inside the strip-shaped hydraulic bladder 705 gradually decreases with the flow, the pressure of the strip-shaped hydraulic bladder 705 on the coil spring 704 becomes smaller, causing the coil spring 704 to wind and reset, and driving the strip-shaped hydraulic bladder 705 to reset. During the reset process of the coil spring 704, the damping column 706 is driven to move. The movement of the damping column 706 drives the cleaning sponge 708 to slide and reset against the wall of the pipe through the moving housing 707. During the reset process of the coil spring 704, one end of its center will rotate and drive the damping column 706 to rotate synchronously. Since the tapered wheel 710 limits the moving housing 707 and the cleaning sponge 708 through the U-shaped frame 709, the damping column 706 will not drive the moving housing 707 to rotate synchronously during the winding process of the coil spring 704, and the cleaning sponge 708 will fit against the wall of the pipe when moving and resetting. The cleaning sponge 708 absorbs the excess lubricating oil flowing out due to extrusion on the wall of the pipe, avoiding waste of lubricating oil. At the same time, the moving housing 707 drives the tapered wheel 710 to roll and reset on the pipe through the U-shaped frame 709, thus realizing the reset of the cleaning and greasing unit 7 and closing the second hydraulic pump.

[0047] After the staff complete the clamping, cleaning, and oiling of the pipe, the staff activate the second hydraulic cylinder 12, causing the output end of the second hydraulic cylinder 12 to extend and push the front support frame 3 to move. The front support frame 3 drives the hydraulic slide rod 5 to move backward through the sliding guide rail 4. The movement of the hydraulic slide rod 5 drives the clamping adjustment unit 6 to move backward, causing the clamping adjustment unit 6 to drive the inserted pipe and the cleaning and oiling unit 7 to move backward synchronously. During the movement of the front cleaning and oiling unit 7, the first extrusion column 10 is driven to move by the sliding plate 712. It should be noted that when the first extrusion column 10 comes into contact with and squeezes the second extrusion column 11, the second extrusion column 11 drives the C-shaped connecting rod 702 to rotate synchronously through the rear short connecting rod 713, causing the C-shaped connecting rod 702 to drive the coil spring 704 and the strip-shaped hydraulic bladder 705 away from the receiving pipe through the outer shell 703. Thus, the coil spring 704 controls the moving shell 707 to drive the cleaning sponge 708, the U-shaped frame 709, and the tapered wheel 710 away from the receiving pipe through the damping column 706. The first extrusion column 10 drives the bent connecting rod 7021 to rotate synchronously through the front short connecting rod 713, causing the bent connecting rod 7021 to drive the coil spring 704 and the strip-shaped hydraulic bladder 705 away from the inserted pipe through the outer shell 703. Thus, the coil spring 704 controls the moving shell 707 to drive the cleaning sponge 708, the U-shaped frame 709, and the tapered wheel 710 away from the inserted pipe. Subsequently, the inserted pipe is inserted into the receiving pipe. The staff adjust the external first hydraulic pump, and a negative pressure is generated inside the first hydraulic pump, causing the hydraulic oil in the first chute of the sliding guide rail 4 to flow back to the first hydraulic pump through the first hose and driving the hydraulic slide rod 5 to move back to its original position. The movement of the hydraulic slide rod 5 back to its original position releases the first elastic member, and the first elastic member drives the limit frame 601 to reset synchronously. The reset of the limit frame 601 drives the rotating guide rail 602 to move back to its original position. The movement of the rotating guide rail 602 causes the rubber roller 604 to disengage from the pipe through the slider 603. At this time, the third elastic member loses the angular restriction of the rotating guide rail 602, so the third elastic member releases and pushes the rotating guide rail 602 to reset its angle. The reset of the angle of the rotating guide rail 602 drives the rubber roller 604 to rotate and reset through the slider 603. When the angle of the rotating guide rail 602 is reset, it drives the connecting rod base 701 to reset its angle, and further causes the bent connecting rod 711 to no longer squeeze the guide rod 714. The U-shaped structure in the middle of the guide rod 714 is released and restored, and moves back to its original position synchronously with the hydraulic slide rod 5, thus completing the reset of the cleaning and oiling unit 7.

[0048] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
