[0002] The UV-curable pipe liner positioning device is a specialized piece of equipment used for trenchless repair of underground pipelines. Its core function is to precisely position and fix the UV-curable liner inside the pipeline, ensuring that the liner is tightly fitted to the old pipeline during the UV curing process, ultimately forming a high-strength new pipe layer. After the liner enters the old pipe, it needs to be pulled by a traction device. However, the existing old pipe may have a lot of debris inside, which can easily get stuck between the liner and the old pipe after traction, affecting the repair effect. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an inner liner traction device for ultraviolet light curing pipe repair, which has the advantage of being able to clean debris from old pipes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a traction device for an inner liner pipe used in ultraviolet curing pipe repair, comprising a soil layer, an old pipe disposed inside the soil layer, a fixing plate fixedly installed above the soil layer, a motor fixedly installed in front of the fixing plate, an output shaft fixedly installed at the output end of the motor, a take-up drum fixedly installed behind the output shaft, a traction line wound around the surface of the take-up drum, a pull block fixedly installed at the end of the traction line away from the take-up drum, a cleaning plate fixedly installed on the outside of the pull block, the connection between the pull block and the cleaning plate being a cavity, and the outside of the cleaning plate contacting the inside of the old pipe.

[0005] As a preferred technical solution of this utility model, a bracket is fixedly installed above the soil layer, and a limiting shaft is rotatably connected inside the bracket, which is in contact with the traction line.

[0006] As a preferred technical solution of this utility model, a second traction line is fixedly installed on the right side of the pull block, a connecting block is fixedly installed on the right side of the second traction line, a bottom support is fixedly installed at the bottom of the connecting block, a sliding groove is opened inside the connecting block, a slider is slidably connected inside the sliding groove, a connecting plate is fixedly installed on the right side of the slider, and a locking tooth is fixedly installed at the bottom of the connecting plate.

[0007] As a preferred embodiment of this utility model, a positioning plate is fixedly installed on the outer side of the connecting block, a second motor is fixedly installed above the positioning plate, and a lead screw is fixedly installed at the output end of the second motor, the lead screw engaging with the connecting plate.

[0008] As a preferred embodiment of this utility model, a second support is fixedly installed above the soil layer, a second limiting shaft is rotatably connected inside the second support, and a guide groove is fixedly installed on the outside of the second limiting shaft.

[0009] As a preferred embodiment of this utility model, there are multiple locking teeth, and all of the multiple locking teeth are located above the bottom support.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model involves winding a traction line around the surface of a take-up drum, with a pull block fixedly installed at the end of the traction line away from the take-up drum. A cleaning plate is fixedly installed on the outside of the pull block, and the connection between the pull block and the cleaning plate is a cavity. The outside of the cleaning plate contacts the inside of the old pipe. First, a motor is started, which drives the take-up drum to rotate through the output shaft, causing the take-up drum to tighten the traction line and cause the traction line to retract around the outside of the take-up drum. At this time, the traction line will drive the pull block to move to the left side of the soil layer. Since the outside of the cleaning plate contacts the inside of the old pipe, and the connection between the pull block and the cleaning plate is a cavity, as the pull block moves to the left, it will scoop up the debris inside the old pipe and collect it in the cavity between the cleaning plate and the pull block. This cleans the debris inside the old pipe, ensuring that there is no debris obstructing the repair process between the inner liner pipe and the old pipe, thus guaranteeing the efficiency of the repair.

[0012] 2. This utility model features a connecting block fixedly installed on the right side of the second traction line, a bottom support fixedly installed at the bottom of the connecting block, a groove inside the connecting block, a slider slidably connected inside the groove, and a connecting plate fixedly installed on the right side of the slider. Simultaneously, a locking tooth is fixedly installed at the bottom of the connecting plate. When the inner lining tube needs to be pulled, the left side of the inner lining tube is first placed above the bottom support. Then, the connecting plate is moved downwards through the sliding connection between the slider and the groove, bringing the connecting plate into contact with the surface of the inner lining tube. Since the bottom of the locking tooth is conical, when the bottom of the locking tooth contacts the inner lining tube, it engages, squeezing the inner lining tube between the connecting plate and the bottom support and limiting its position, thus facilitating the pulling of the inner lining tube.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides an inner liner traction device for ultraviolet curing pipe repair, including a soil layer 1, an old pipe 2 inside the soil layer 1, a fixing plate 3 fixedly installed above the soil layer 1, a motor 4 fixedly installed in front of the fixing plate 3, an output shaft 5 fixedly installed at the output end of the motor 4, a take-up drum 6 fixedly installed behind the output shaft 5, a traction line 7 wound on the surface of the take-up drum 6, a pull block 8 fixedly installed at the end of the traction line 7 away from the take-up drum 6, a cleaning plate 9 fixedly installed on the outside of the pull block 8, the connection between the pull block 8 and the cleaning plate 9 is a cavity, and the outside of the cleaning plate 9 contacts the inside of the old pipe 2.

[0021] First, the motor 4 is started, which drives the take-up drum 6 to rotate via the output shaft 5. This causes the take-up drum 6 to tighten the traction line 7 and retract it by winding it around the outside of the take-up drum 6. At this time, the traction line 7 will drive the pull block 8 to move to the left side of the soil layer 1. Since the outside of the cleaning plate 9 is in contact with the inside of the old pipe 2, and the connection between the pull block 8 and the cleaning plate 9 is in a cavity, the debris inside the old pipe 2 will be scooped up as the pull block 8 moves to the left and collected by the cavity between the cleaning plate 9 and the pull block 8. This cleans the debris inside the old pipe 2, ensuring that there is no debris obstructing the repair process between the inner liner pipe and the old pipe 2, thus guaranteeing the efficiency of the repair.

[0022] Among them, a bracket 10 is fixedly installed above the soil layer 1. The bracket 10 is internally connected to a limiting shaft 11, which is in contact with the traction line 7.

[0023] The main function of the limiting pivot 11 is to reduce the friction between the traction line 7 and other components while ensuring that the traction line 7 can be limited, thereby increasing the service life of the traction line 7.

[0024] Among them, a second traction line 15 is fixedly installed on the right side of the pull block 8, a connecting block 16 is fixedly installed on the right side of the second traction line 15, a bottom support 17 is fixedly installed at the bottom of the connecting block 16, a sliding groove 18 is opened inside the connecting block 16, a slider 19 is slidably connected inside the sliding groove 18, a connecting plate 20 is fixedly installed on the right side of the slider 19, and a locking tooth 21 is fixedly installed at the bottom of the connecting plate 20.

[0025] When the inner liner tube needs to be pulled, first place the left side of the inner liner tube above the bottom support 17. Then, move the connecting plate 20 downward through the sliding connection between the slider 19 and the slide groove 18, so that the connecting plate 20 contacts the surface of the inner liner tube. Since the bottom of the locking tooth 21 is conical, when the bottom of the locking tooth 21 contacts the inner liner tube, it will lock the inner liner tube, so that the inner liner tube is squeezed between the connecting plate 20 and the bottom support 17 and is limited, thus making the inner liner tube easy to pull.

[0026] A positioning plate 22 is fixedly installed on the outer side of the connecting block 16, a second motor 23 is fixedly installed on the top of the positioning plate 22, and a lead screw 24 is fixedly installed on the output end of the second motor 23. The lead screw 24 meshes with the connecting plate 20.

[0027] After the start motor 23 drives the lead screw 24 to rotate, the lead screw 24 will mesh with the connecting plate 20, thereby causing the connecting plate 20 to move up and down through the sliding connection between the slider 19 and the slide groove 18, so as to achieve the effect of easy locking.

[0028] Among them, a bracket 12 is fixedly installed above the soil layer 1. The bracket 12 is rotatably connected to a limiting shaft 13, and a guide groove 14 is fixedly installed on the outside of the limiting shaft 13.

[0029] The traction line 7 and the guide groove 14 are rotatably connected, and the guide groove 14 has a certain limiting effect on the traction line 7, and keeps the traction line 7 coaxial with the soil layer 1 at all times.

[0030] There are multiple locking teeth 21, and all of the locking teeth 21 are located above the bottom support 17.

[0031] The main function of the multiple locking teeth 21 is to evenly lock the inner liner tube, so that the inner liner tube will not fall off during the traction process.

[0032] Working principle and usage process of this utility model:

[0033] First, a traction line 7 is wound around the surface of the take-up drum 6, and a pull block 8 is fixedly installed at the end of the traction line 7 away from the take-up drum 6. A cleaning plate 9 is fixedly installed on the outside of the pull block 8. At the same time, the connection between the pull block 8 and the cleaning plate 9 is a cavity, and the outside of the cleaning plate 9 contacts the inside of the old pipe 2. The start motor 4 drives the take-up drum 6 to rotate through the output shaft 5, so that the take-up drum 6 tightens the traction line 7 and the traction line 7 is wound around the outside of the take-up drum 6 and retracts. At this time, the traction line 7 will drive the pull block 8 to move to the left side of the soil layer 1. Since the outside of the cleaning plate 9 contacts the inside of the old pipe 2 and the connection between the pull block 8 and the cleaning plate 9 is a cavity, the debris inside the old pipe 2 will be scooped up and collected by the cavity between the cleaning plate 9 and the pull block 8 as the pull block 8 moves to the left. This cleans the debris inside the old pipe 2, so that there will be no debris blocking the inner liner pipe and the old pipe 2 during the repair process.

[0034] Secondly, since a connecting block 16 is fixedly installed on the right side of the traction line 15, and a bottom support 17 is fixedly installed at the bottom of the connecting block 16, a groove 18 is opened inside the connecting block 16, and a slider 19 is slidably connected inside the groove 18. A connecting plate 20 is fixedly installed on the right side of the slider 19, and a locking tooth 21 is fixedly installed at the bottom of the connecting plate 20. When traction is performed, the left side of the inner liner tube is placed above the bottom support 17. After the motor 23 is started and the screw 24 is driven to rotate, the screw 24 will mesh with the connecting plate 20, so that the connecting plate 20 moves up and down through the sliding connection between the slider 19 and the groove 18, so that the locking tooth 21 contacts the surface of the inner liner tube. Since the bottom of the locking tooth 21 is conical, when the bottom of the locking tooth 21 contacts the inner liner tube, it will lock the inner liner tube, so that the inner liner tube is squeezed between the connecting plate 20 and the bottom support 17 and is limited.

[0035] Finally, the clamped inner liner tube is driven by traction line 2 15 and moves to the left together with pull block 8, achieving the effect of being pulled to the other end.
