Description

Technical Field

[0001] The utility model belongs to the technical field of water pipe repair, and in particular relates to a pressure repair structure for a large-diameter PE water supply pipeline. Background Art

[0002] PE (polyethylene) material is widely used in the field of water pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water pipes. Since water pipes are buried underground for a long time, they are easy to be damaged. Usually, they are repaired by compressing the damaged parts with a test ring. However, the repair may cause the water pipe to be compressed and deformed, which may lead to further damage. Now a device is proposed that can prevent the water pipe from being compressed and deformed during repair. Utility Model Content

[0013] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0014] See also Figures 1 to 3, provided in one embodiment of the utility model, is a large-diameter PE water supply pipe pressure repair structure, including a frame 101, and also including:

[0015] Support assembly 2, used to prevent the repaired pipe from breaking;

[0021] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific screw rod 207 described in the above embodiment. For example, the screw rod 207 can be a reciprocating screw rod. The purpose of this setting is that when the slider threadedly connected to the reciprocating screw rod moves to one end, it can continue to rotate in the same direction, thereby quickly changing the movement direction of the slider, and in this way preventing the tube body from being squeezed and damaged.

For example, the wheel grooves of the pulleys A302 and B304 should have a certain depth. The purpose of this setting is to facilitate strengthening the limiting effect of the belt 303 in this way, thereby preventing slipping and dislocation during transmission.

[0026] Specifically, an eccentric wheel 305 is fixedly connected to the axis of the pulley B304 , and the eccentric wheel 305 is rotatably connected to the frame 101 .

[0027] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific eccentric wheel 305 described in the above embodiment. For example, a bearing ring is provided at the connection between the eccentric wheel 305 and the frame 101. The purpose of this arrangement is to prevent the shaft from breaking due to long-term use.

[0028] Specifically, the eccentric wheel 305 is rotatably connected to a push rod 306 at its eccentric position, the other end of the push rod 306 is hinged to a ring sleeve 307 , and the ring sleeve 307 is slidably connected to the frame 101 .

[0030] Specifically, a gear 308 is fixedly connected to the eccentric wheel 305 , and the gear 308 is meshedly connected with a gear fixedly assembled on the output shaft of the motor 309 , and the motor 309 is fixedly connected to the frame 101 .

[0031] In the embodiment of the utility model, the relevant technicians put the water pipe through the ring sleeve 307 and put it on multiple support rods B204, and start the motor 309, so that the gear 308 drives the eccentric wheel 305 fixedly connected at its axis to start rotating, and the pulley B304 fixedly connected to the eccentric wheel 305 starts rotating, so that the pulley A302 starts to rotate synchronously with the pulley B304 under the cooperation of the belt 303 connected to it for transmission, so that the guide rod 301 fixedly connected at the axis of the pulley A302 rotates synchronously, so that the guide rod 301 drives the worm 209 fixedly connected thereto to rotate synchronously, so that the worm 209 drives the worm wheel 208 meshing with it to rotate synchronously, so that the screw rod 207 fixedly connected at the axis of the worm wheel 208 starts to rotate, so that the screw rod 207 drives the slide cylinder 20 connected to it with a thread. 2 rotates synchronously, so that the slide 202 starts to push the support rod A203 hinged thereto, so that the support rod A203 starts to push the support plate 206 hinged thereto, so that the slider 205 slidably connected to the other side of the support plate 206 starts to slide, so that the support rod B204 hinged thereon starts to move synchronously, so that the multiple support plates 206 start to contact the inner wall of the water pipe with the cooperation of the support rods A203 and B204, and tighten and support it to prevent the water pipe from being crushed when the pressure ring is inserted. At the same time, when the eccentric wheel 305 rotates, the push rod 306 rotatably connected thereto starts to move synchronously, so that the push rod 306 starts to push the ring sleeve 307 hinged thereto, so that the ring sleeve 307 starts to circulate and wipe and clean the outer wall of the water pipe, so as to prevent impurities from existing on the pipe body when the water stop sticker is pasted, resulting in the water stop sticker being unable to be effectively adsorbed on the pipe body.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0034] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0035] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0036] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
