Abstract
Description
Technical Field
[0001] This invention belongs to the field of water supply and drainage, and specifically relates to a water supply and drainage pipeline connection device. Background Technology
[0002] In water supply and drainage pipeline construction, pipeline connection is a crucial step. Existing connection methods, such as the pipeline connection equipment for water conservancy projects disclosed in CN116972231A, include a frame, a T-shaped movable frame, a bidirectional screw, and an openable and closable fixing ring. The bidirectional screw is rotatably mounted on the frame, the T-shaped movable frame is slidably mounted on the frame, and a threaded sleeve is rotatably mounted on the T-shaped movable frame, which is threadedly connected to the bidirectional screw. The T-shaped movable frame also has a locking mechanism for locking the rotational freedom of the threaded sleeve. The fixing ring is mounted on the T-shaped movable frame, and a clamping mechanism is rotatably mounted on one side of the T-shaped movable frame. A retaining sleeve is located on one side of the fixing ring, and the clamping mechanism closes and clamps the fixing ring by rotating into the retaining sleeve. A drive motor is located on one side of the frame, and the drive motor is connected to one end of the bidirectional screw via a coupling. Limiting rods are provided on both sides of the frame. The two ends of the T-shaped moving frame are slidably mounted on the limiting rods through sliding sleeves, so that the T-shaped moving frame can move horizontally on the frame under the rotation of the bidirectional screw. When the T-shaped moving frame moves horizontally, it drives the ends of the two pipe sections to move closer to each other, thereby realizing the connection of the pipes.
[0003] However, existing pipes, especially plastic pipes, are prone to deformation at their ends due to the inherent properties of the material and the influence of external forces, resulting in an elliptical shape at the pipe ends. This deformation makes it difficult to insert the pipe into the fitting, and also causes gaps between the pipe and the fitting after connection, affecting the quality of the water supply and drainage pipe connection. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water supply and drainage pipe connection device to solve the problems of difficulty in pipe connection caused by deformation of the end of water supply and drainage pipes, and gaps between the pipe and the pipe joint after connection, which affect the quality of water supply and drainage pipe connection.

[0015] The beneficial effects of this invention are: 1) This invention utilizes a pipe end straightening mechanism to straighten deformed pipe ends, ensuring the quality of pipe connections, especially for plastic pipes. This effectively avoids water leakage caused by gaps at pipe connections, thus guaranteeing the quality of water supply and drainage pipe connections.
[0016] 2) The extension length of the mounting rod of the pipe end straightening mechanism is adjustable, which makes it easy to straighten the pipe end at different depths and reduces the difficulty of pipe connection.
[0017] 3) A second support mechanism is set at the other end of the pipeline. The second support mechanism works with the first support mechanism to support both ends of the pipeline, which prevents the pipeline from forming a cantilever beam structure and causing large bending deformation. At the same time, it ensures the stability of the pipeline connection and reduces the support pressure of the first support mechanism.
[0018] 4) The pipe lifting mechanism is slidably connected to the crossbeam, and a first adjusting screw is threaded to each side of the crossbeam. The two first adjusting screws are used to adjust the position of the pipe lifting mechanism on the crossbeam. The first adjusting screws, together with the second lifting cylinder, facilitate the adjustment of the docking angle of the pipe docking end, ensuring the smooth docking of the pipe.
[0019] 5) Measuring mechanisms for measuring the distance between the pipe opening and the support block are set on both sides of the support block, which facilitates the determination of the distance between the ends of the two pipes and the pipe joints; and a second adjusting screw for pushing the pipes back and forth is set on one side of the support. According to the difference in readings, the handwheel is turned to adjust the position of the pipes on both sides so that the distance between the pipe opening and the pipe joint on both sides is equal, so as to ensure that the insertion depth of the pipe joint is equal when the pipes are connected, thus ensuring the quality of pipe connection.
[0020] 6) A drive mechanism for rotating the pipe is set on one side of the pipe picking mechanism. When the pipe is connected, the second motor drives the drive wheel to rotate through gear transmission, thereby driving the pipe to rotate and screwing the pipe into the pipe joint, which further reduces the difficulty of pipe connection.
[0021] 7) A braking mechanism is installed on both the pipe picking mechanism and one side of the crossbeam. When the pipe end is straightened, the braking mechanism presses against the pipe to prevent the pipe from rotating and ensures the accuracy of the pipe end straightening. When the pipe is connected, the braking mechanism separates from the pipe. At this time, the braking mechanism does not affect the pipe's advance or rotation. Attached Figure Description

[0036] like Figure 1 As shown, a water supply and drainage pipe connection device includes a first support mechanism 1, a pipe picking mechanism 3 symmetrically arranged on both sides of the first support mechanism 1, and a pipe end straightening mechanism 5, as shown. Figure 2 , Figure 3As shown, the first support mechanism 1 includes a base 101, with first sleeves 102 on both sides of the base 101. A first connecting seat 104 is connected between the two first sleeves 102. A support block 105 is provided in the middle of the first connecting seat 104 for placing the pipe connector 2. Two mounting slots are symmetrically provided on both sides of the first connecting seat 104. A V-shaped first clamping arm 106 is hinged in the mounting slot. The lower ends of the two first clamping arms 106 are connected by a first clamping cylinder (not shown in the figure). A first lifting cylinder 118 is provided in the first sleeve 102. A first column 103 is connected to the upper part of the first lifting cylinder 118. The first columns 103 on both sides... The upper end is connected by a connecting frame 111. The lower two sides of the connecting frame 111 are rotatably connected to double-ended studs 117, and the threads on both sides of the double-ended studs 117 are in opposite directions. A first motor 112 is provided on one side of the connecting frame 111. A drive pulley 113 is connected to the output shaft of the first motor 112. A driven pulley 114 is provided on one side of the connecting frame 111. The drive pulley 113 and the driven pulley 114 are connected by a first transmission belt. A transition pulley 115 is provided on one side of both the drive pulley 113 and the driven pulley 114. A drive pulley 116 is provided on the double-ended stud 117. The drive pulley 116 and the transition pulley 115 are connected by a second transmission belt. like Figure 4 As shown, the tube picking mechanism 3 includes a second connecting seat 301. The two sides of the second connecting seat 301 are provided with connecting ears 311 that are threadedly connected to the double-ended stud 117. A second clamping arm 302 is hinged to each side of the second connecting seat 301. The upper part of the second clamping arm 302 is connected through a second clamping cylinder 310. like Figure 8 As shown, the pipe end straightening mechanism 5 includes two semi-circular hoops 501, which are detachably connected by fastening bolts 502. Several mounting rods 503 are provided in the circumferential direction of the semi-circular hoops 501, and the ends of the mounting rods 503 are threadedly connected to tightening bolts 504.
[0037] like Figure 9 As shown, the mounting rod 503 and the semi-circular hoop 501 are clearance-fitted. A rod sleeve 505 is fixedly connected to one side of the semi-circular hoop 501. The semi-circular hoop 501 is intermittently disposed inside the rod sleeve 505. An adjusting bolt 506 is threadedly connected to one side of the rod sleeve 505, which facilitates adjusting the length of the mounting rod 503 extending out of the semi-circular hoop 501. This allows for the correction of different positions of the pipe opening within a certain range, reducing the difficulty of pipe connection.
[0038] like Figure 1 , Figures 9-10As shown, the first support mechanism 1 is provided with second support mechanisms 6 on both sides. The second support mechanisms 6 are located at the other end of the pipe 7. The second support mechanism 6 includes two base plates 601. A second sleeve 602 is provided on the upper part of the base plate 601. A second lifting cylinder 604 is provided inside the second sleeve 602. A second column 603 is connected to the upper part of the second lifting cylinder 604, and the second column 603 is intermittently disposed inside the second sleeve 602. Support frames 607 are connected to the upper parts of the second columns 603 on both sides. Guide rods 605 are fixedly connected to both sides of the support frame 607. A second guide sleeve 605 is intermittently sleeved on the lower part of the guide rod 605. 6. The lower end of the second guide sleeve 606 is fixedly installed on the base plate 601; the support frame 607 is provided with a crossbeam 608, and the crossbeam 608 is provided with a pipe lifting mechanism 609. The pipe lifting mechanism 609 includes a third connecting seat 6091, and a third clamping arm 6092 is hinged to each side of the third connecting seat 6091. The upper parts of the two third clamping arms 6092 are connected by a third clamping cylinder 6094; the second support mechanism 6 supports the other end of the pipe 7, avoiding the pipe 7 from forming a cantilever beam structure, causing the pipe to bend and deformed significantly, while ensuring the stability of the pipe connection and reducing the support pressure of the first support mechanism 1.
[0039] like Figure 10 As shown, further, guide grooves are provided on the inner walls of both sides of the crossbeam 608, and the pipe lifting mechanism 609 is slidably installed inside the guide grooves on both sides. The crossbeam 608 is threadedly connected to the first adjusting screws 610 on both sides. By rotating the first adjusting screws 610 on both sides, the position of the pipe lifting mechanism 609 on the crossbeam 608 is adjusted, thereby adjusting the docking angle of the pipe docking end, so that the pipe docking end is coaxial with the pipe joint 2, ensuring the smooth docking of the pipe.
[0040] like Figure 7 As shown, the support block 105 has two slots 107, each slot 107 has an insert plate 108, and the insert plate 108 has scale lines. One end of the insert plate 108 is fixedly connected to a fixing plate 109, and the two fixing plates 109 are located on both sides of the support block 105. A rotating plate 110 is hinged to one side of the fixing plate 109. When the pipes 7 are connected, the first support mechanism 1 lifts one end of the pipe 7, pulls the insert plate 108 out of the slot 107, and rotates the rotating plate 110 so that the rotating plate 110 abuts against the pipe opening. The distance between the pipe openings and the pipe joint 2 on both sides is read. Based on the difference in readings, the positions of the pipes on both sides are adjusted so that the distance between the pipe openings and the pipe joint 2 on both sides is equal, so as to ensure that the insertion depth of the pipe joint 2 is equal when the pipes are connected, thus ensuring the quality of the pipe connection.
[0041] like Figure 10As shown, the support frame 607 has sliding grooves 611 on both sides, and the crossbeam 608 has sliders at both ends. The sliders are slidably installed in the sliding grooves 611. A second adjusting screw 612 is threadedly connected to one side of the support frame 607. One end of the second adjusting screw 612 is equipped with a handwheel 613, and the other end of the second adjusting screw 612 is movably connected to the crossbeam 608. By rotating the handwheel 613, the position of the crossbeam 608 on the support frame 607 can be adjusted using the second adjusting screw 612, thereby adjusting the distance between the pipe opening and the pipe connector 2, avoiding manual lifting and reducing the labor intensity of the operator.
[0042] like Figures 4-5 As shown, a drive wheel 304 is rotatably connected to the lower part of the second connecting seat 301. The lower end of the drive wheel 304 abuts against the outer wall of the pipe 7. A gearbox 305 is provided on one side of the pipe picking mechanism 3, and a second motor 309 is provided on one side of the gearbox 305. The output shaft of the second motor 309 is connected to a drive gear 306. A transition gear 307 meshes with the lower part of the drive gear 306, and a driven gear 308 meshes with the lower part of the transition gear 307. The driven gear 308 is fixedly connected to the axle of the drive wheel 304. When the pipe is connected, the second motor 309 drives the drive wheel 304 to rotate through gear transmission, thereby driving the pipe to rotate and causing the pipe to be screwed into the pipe joint 2, further reducing the difficulty of pipe connection.
[0043] like Figure 4 , Figure 11 As shown, the lower end of the second clamping arm 302 is rotatably connected to the first roller 303, and the first roller 303 is arranged parallel to the pipe 7, which reduces the friction when the pipe rotates; the lower end of the third clamping arm 6092 is rotatably connected to the second roller 6093, and the second roller 6093 is arranged perpendicular to the axis of the pipe 7, which ensures the smoothness of the pipe when moving back and forth.
[0044] like Figure 4 , Figure 6 , Figure 10As shown, both the tube-picking mechanism 3 and the crossbeam 608 are equipped with a braking mechanism 4 on one side. The braking mechanism 4 includes a fixing plate 401, and a base 402 is connected to one side of the fixing plate 401. A first guide sleeve 403 is provided at the lower end of the base 402. A pressure rod 404 is slidably connected inside the first guide sleeve 403. A first connecting rod 405 is hinged to the upper end of the pressure rod 404. A second connecting rod 406 is hinged to the upper end of the base 402. The other end of the first connecting rod 405 is hinged to the middle of the second connecting rod 406. The upper part of the 06 is provided with a handle 407; the lower end of the pressure rod 404 is provided with an end plate, the lower part of the end plate is provided with a pressure plate 411, the lower part of the pressure plate 411 is provided with a pressure seat 412, and the lower part of the pressure seat 412 is an arc-shaped surface; when the pipe end is straightened, the handle 407 is pulled down to press the pressure seat 412 against the pipe 7, preventing the pipe from rotating and ensuring the accuracy of the pipe end straightening; when the pipe is connected, the handle 407 is pulled up to separate the pressure seat 412 from the pipe 7. At this time, the braking mechanism 4 does not affect the advancement and rotation of the pipe.
[0045] like Figure 6 As shown, the end plate is provided with adjusting rods 409 on both sides. The lower end of the adjusting rod 409 extends to the lower part of the pressure plate 411 and is threaded with a nut. A spring 410 is sleeved on the outer part of the adjusting rod 409 and is located between the end plate and the pressure plate 411. A guide rail 413 is provided on one side of the fixed plate 401. The pressure plate 411 is slidably mounted on the guide rail 413. The adjusting rod 409 facilitates the adjustment of the height of the pressure plate 411 and the pressure seat 412, thereby adapting to the connection of pipes 7 of different diameters.
[0046] When connecting water supply and drainage pipes, the first support mechanism 1 is moved between the two pipe sections 7, and the second support mechanism 6 is moved to the end of the pipe 7. The second clamping cylinder 310 and the third clamping cylinder 6094 are controlled to retract, so that the lower ends of the second clamping arm 302 and the third clamping arm 6092 open. Then, the first lifting cylinder 118 and the second lifting cylinder 604 are controlled to retract, so that the pipe picking mechanism 3 and the pipe lifting mechanism 609 descend. When the second clamping arm 302 and the third clamping arm 6092 cover the pipe, the second clamping cylinder 310 and the third clamping cylinder 6094 are controlled to extend, and the pipe is clamped by the second clamping arm 302 and the third clamping arm 6092. Then, the first lifting cylinder 118 and the second lifting cylinder 604 are controlled to extend, so that the pipe is lifted.
[0047] After the pipe is lifted, the pipe end straightening mechanism 5 is installed at the pipe connection end. According to the deformation position of the pipe, the corresponding tightening bolt 504 is rotated to correct the deformation of the pipe end, so that the pipe end is as round as possible. Then the connection position of the pipe is cleaned in preparation for connection.
[0048] Place the pipe connector 2 on the support block 105, adjust the position of the pipe connector 2 so that the distances from both sides of the pipe connector 2 to the end face of the support block 105 are equal, then control the action of the first clamping cylinder to clamp the pipe connector 2 using the first clamping arm 106; then pull the insert plate 108 out of the slot 107 and rotate the rotating plate 110 so that the rotating plate 110 abuts against the pipe opening, read the distances between the pipe openings on both sides and the pipe connector 2 respectively, and adjust the position of the pipes on both sides according to the difference in readings so that the distances between the pipe openings on both sides and the pipe connector 2 are equal, so as to ensure that the insertion depth of the pipe connector 2 is equal when the pipes are connected; when adjusting the position of the pipe, the second adjusting screw 612 of the second support mechanism 6 can be used to push the crossbeam 608 to move back and forth on the support frame 607.
[0049] When connecting pipes, first start the first motor 112, and use the double-ended stud 117 to drive the pipe picking mechanisms 3 on both sides to approach each other. When the pipe opening is about to contact the pipe joint 2, stop the first motor 112 and observe whether the pipe opening and the pipe joint 2 are aligned. If they are not aligned, the second lifting cylinder 604 can be used in conjunction with the first adjusting screw 610 to adjust the rotation angle of the end of the pipe 7 so that the pipe opening and the pipe joint 2 are aligned. Then start the first motor 112 again and start the second motor 309 at the same time. The first motor 112 uses the double-ended stud 117 to drive the pipe 7 to move horizontally, while the second motor 309 drives the pipe 7 to rotate through gear transmission, so that the pipe is in a spiral state, which reduces the difficulty of connecting pipes.
[0050] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
