The end face of the pipe material is heated to a molten state by a heating device (such as a hot melting machine), and then the molten end face is tightly butt-jointed and pressure is applied, so that a firm connection is formed after cooling. However, when the pipe is damaged during use and needs to be repaired, a discontinuity point appears on the pipe after the damaged part is removed. At this time, the two ends cannot be connected. Therefore, the present application provides a device for welding and repairing the pipe with discontinuity. SUMMARY

[0011] Beneficial effects
[0012] This invention provides a PE water pipe welding device, which has the following advantages compared with the prior art:
[0013] 1. The user places the frame vertically above the broken PE pipe and presses it down to insert the broken PE pipe into the frame. The user then activates the heating plate to heat it up, melting the semi-circular tube attached to its surface. At this point, the inner wall and both ends of the semi-circular tube begin to melt. The user then adjusts the position of the heating plate using the adjustment components to avoid interfering with the rotation of the semi-circular tube. The user then starts the motor, causing the gear fixed at its shaft to rotate at a constant speed. Since the gears on both the upper and lower sides are meshed, the two frames begin to move towards each other, causing the semi-circular tube to gradually slide towards the PE pipe and form a complete ring while adhering to the surface of the PE pipe. The user then continues to start the motor, causing the clamp to apply horizontal pressure to the semi-circular tube, allowing the ends of the two semi-circular tubes to weld together. Simultaneously, the inner wall of the semi-circular tube welds to the outer wall of the PE pipe, thus connecting the broken PE pipe. Because the semi-circular tube is welded to the outer wall of the PE pipe, the tightness of the connection is effectively increased, preventing water leakage at the joint.
[0014] 2. When the gear starts to rotate, the pulley A fixedly connected to it starts to rotate. At this time, the pulley B starts to rotate at a constant speed under the cooperation of the belt connected to its drive, and the reciprocating screw fixedly connected to its shaft starts to rotate at a constant speed. At this time, the sliding rod connected to its thread starts to slide to the left to clean the impurities on the PE pipe on the left. Then, when it slides to the left end of the reciprocating screw, it starts to change direction and slides to the other side of the PE pipe, thereby wiping and cleaning the connection until it slides against the end face of the frame. At this time, the two semi-circular tubes are synchronously attached to the PE pipe, thereby avoiding the cleaning ring from interfering with the sliding of the semi-circular tubes.
[0015] 3. After the semi-circular tubes have melted completely, the user should reverse the motor to detach the semi-circular tubes from the surface of the heating plate. Then, the user can start motor A, causing the main gear fixed to its output shaft to rotate at a constant speed. Simultaneously, since gear rings are meshed on both the upper and lower sides, the two gear rings begin to rotate towards each other. At this time, gear ring B and the connecting block begin to rotate synchronously, driving the connecting rods connected to it. The connecting rods then begin to slide along the arc-shaped groove at their connection with the frame, causing both connecting rods to slide upwards synchronously. This causes the heating plate to slide upwards and detach from the semi-circular tube's movement track. This design avoids interference with the movement of the semi-circular tube. Simultaneously, as the connecting rod slides upwards, it drives the fixed gear A to slide upwards synchronously. Since gear A is meshed with gear ring B, its upward sliding causes the collar to rotate. At this point, the inner liner ring rotates against the outer wall of the PE tube. When the connecting rod slides to its maximum extent, the inner liner ring moves to the underside of the PE tube. Because the inner liner ring is tightly against the outer wall of the PE tube, it positions the PE tube at the top of the groove in the frame, thus preventing the PE tube from shaking during welding and causing misalignment during the connection.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention 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 invention and are not intended to limit the invention.
[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0025] Please see Figures 1-6According to one embodiment of the present invention, a PE water pipe welding device includes a frame 101, a PE pipe 201, a docking assembly, and an adjustment assembly. The frame 101 has a groove on its bottom side, through which the PE pipe 201 is inserted into the center of the frame 101. Semicircular pipes 202 are symmetrically arranged on both sides of the PE pipe 201, and the two semicircular pipes 202 form a complete ring. The inner diameter of the ring is equal to the outer diameter of the PE pipe 201. The semicircular pipes 202 are attached to the corresponding heating plates 203, and connecting rods 204 are fixedly connected to the center of the heating plates 203. The connecting rods 204 are slidably connected in the arc-shaped grooves on the side wall of the frame 101, and the connecting rods 204 are inserted into the corresponding sleeves 205, with the sleeves 205 fitting against the arc surface of the semicircular pipes 202.
[0026] The docking assembly is used to dock the two semi-circular tubes 202 together; the adjusting assembly is used to adjust the position of the heating plate 203.
[0027] Specifically, the docking assembly includes a frame 206, a rack 207, and a wiping assembly. The two frames 206 extend through the grooves on both sides of the frame 101, and the ends of the two frames 206 are interlocked. The two racks 207 are fixedly connected to the upper and lower surfaces of the two frames 206, respectively, and a gear 208 is meshed between the two racks 207. The gear 208 is fixedly connected to the output shaft of the motor 209, and the motor 209 is fixedly connected to the frame 101.
[0028] The wiping assembly is used to wipe away stains on the surface of the PE pipe 201.
[0029] In the above embodiment, the user places the frame 101 vertically above the broken PE pipe 201 and presses the frame 101 downwards, causing the broken PE pipe 201 to be inserted into the frame 101. At this time, the user can activate the heating plate 203 to heat it up, thereby melting the semi-circular pipe 202 adhered to its surface. That is, at this time, the inner wall and both ends of the semi-circular pipe 202 begin to melt. Then, the user adjusts the position of the heating plate 203 by adjusting the component to avoid interfering with the rotation of the semi-circular pipe 202. Then, the user should start the motor 209, so that the gear 208 fixedly connected to its shaft begins to rotate at a constant speed. At this time, since both the upper and lower sides are meshed... With a rack 207, the two frames 206 begin to move towards each other, causing the semicircular tube 202 to gradually slide towards the PE tube 201 between them, forming a complete ring while adhering to the surface of the PE tube 201. At this time, the user continues to start the motor 209, causing the clamp 205 to apply horizontal pressure to the semicircular tube 202, so that the end faces of the two semicircular tubes 202 can be welded together. At the same time, the inner wall of the semicircular tube 202 can be welded to the outer wall of the PE tube 201, thereby connecting the broken PE tube 201. Since the semicircular tube 202 is welded to the outer wall of the PE tube 201, it can effectively increase the tightness of the connection and prevent water leakage at the connection point.
[0030] Specifically, the wiping assembly includes a cleaning ring 306, a slide bar 305, and a transmission assembly. The cleaning ring 306 is coaxial with the PE pipe 201 and fits against the outer wall of the frame 206. The bottom of the cleaning ring 306 is provided with a break. The cleaning ring 306 is fixedly connected to the bottom end of the slide bar 305, and the slide bar 305 is slidably connected to the frame 101.
[0031] The transmission assembly is used to make the slide bar 305 slide laterally.
[0032] Specifically, the transmission assembly includes a reciprocating lead screw 304 and a drive assembly. The slide bar 305 is threadedly connected to the reciprocating lead screw 304, and the reciprocating lead screw 304 is horizontally arranged in a groove at the top of the frame 101 and rotatably connected to the frame 101. The end of the reciprocating lead screw 304 extends through the frame 101.
[0033] The drive assembly is used to make the cleaning ring 306 move synchronously with the semi-circular tube 202.
[0034] Specifically, the drive assembly includes a pulley B303, which is fixedly connected to a reciprocating lead screw 304, and a belt 302 is drivenly connected to the pulley B303. The other end of the belt 302 is drivenly connected to a pulley A301, which is fixedly connected to a gear 208.
[0035] In the above embodiment, when gear 208 starts to rotate, pulley A301 fixedly connected to it starts to rotate. At this time, pulley B303 starts to rotate at a constant speed in cooperation with belt 302 connected to it, causing reciprocating screw 304 fixedly connected to its shaft to start rotating at a constant speed. At this time, sliding rod 305 threadedly connected to it starts to slide to the left to clean impurities on the PE pipe 201 on its left side. Then, when it slides to the left end of reciprocating screw 304, it starts to change direction and slides towards the PE pipe 201 on the other side to wipe and clean the connection until it slides against the end face of frame 101. At this time, the two semi-circular tubes 202 are synchronously attached to the PE pipe 201, thereby avoiding the cleaning ring 306 interfering with the sliding of the semi-circular tubes 202.
[0036] Specifically, the adjustment assembly includes a connecting block B406, a connecting block 307, and a fastening assembly. The ends of the two connecting rods 204 are rotatably connected to the connecting block B406 and the connecting block 307, respectively. The connecting block B406 and the connecting block 307 are slidably connected in an arc-shaped groove in the frame 101. Gear rings 308 are fixedly connected to the upper surface of the connecting block B406 and the lower surface of the connecting block 307, respectively. A main gear 309 is meshed between the two gear rings 308. The main gear 309 is fixedly connected to the output shaft of the motor A401. The motor A401 is fixedly connected to the frame 101.
[0037] The fastening assembly is used to prevent the PE pipe 201 from shifting.
[0038] Specifically, the fastening assembly includes a gear A402 and a gear ring B403. The gear A402 is fixedly connected to the corresponding connecting rod 204, and the gear A402 is meshed with the gear ring B403. The gear ring B403 is fixedly connected to the outer wall of the collar 404, and an inner liner ring 405 is fixedly connected to the inner wall of the collar 404. The inner liner ring 405 is attached to the outer wall of the PE pipe 201.
[0039] In the above embodiment, after the semicircular tube 202 has melted completely, the user should reverse the motor 209 to disengage the semicircular tubes 202 from the surface of the heating plate 203. The user can then start the motor A401, causing the main gear 309 fixedly connected to its output shaft to rotate at a constant speed. Simultaneously, since gear rings 308 are meshed on both its upper and lower sides, the two gear rings 308 begin to rotate towards each other. At this time, the gear ring B403 and the connecting block 307 begin to rotate synchronously, driving the connecting rod 204 rotatably connected to it. This causes the connecting rod 204 to slide along the arc-shaped groove at its connection with the frame 101, meaning the two connecting rods 204 slide upwards synchronously, causing the heating plate 203 to slide upwards and disengage from the semicircular tube 202. The movement trajectory avoids interference with the movement of the semi-circular tube 202. Simultaneously, as the connecting rod 204 slides upward, it drives the gear A402, which is fixedly connected to it, to slide upward synchronously. Since gear A402 is meshed with gear ring B403, its upward sliding causes the collar 404 to rotate. At this time, the inner liner ring 405 rotates against the outer wall of the PE tube 201. When the connecting rod 204 slides to its maximum extent, the inner liner ring 405 moves to the lower side of the PE tube 201. Because the inner liner ring 405 is tightly against the outer wall of the PE tube 201, it positions the PE tube 201 at the top of the groove in the frame 101, thus preventing the PE tube 201 from shaking during welding and causing misalignment during the connection.
[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0041] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.
[0042] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.
[0043] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.
[0044] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.
[0045] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
