[0001] This utility model relates to the field of pipeline repair technology, and more specifically, to a pipeline repair glue injection gun structure. Background Technology

[0002] Pipeline repair caulking guns are core tools used in trenchless repair of municipal pipelines. Their core function is to precisely and under high pressure inject mixed resin material into damaged areas inside the pipeline, filling cracks, sealing leaks, and restoring structural strength. However, existing pipeline repair guns often struggle to evenly mix and spray the injected caulking agent, resulting in inconsistent overall repair effectiveness. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a pipe repair glue gun structure, which has the advantage of convenient repair.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipe repair glue injection gun structure, including a pipe, a gun barrel inside the pipe, a motor fixedly installed on the left side of the gun barrel, an output shaft fixedly installed at the output end of the motor, a spiral blade fixedly installed on the outer side of the output shaft, a connecting rod fixedly installed on the left side of the output shaft, a bracket fixedly installed on the outer side of the connecting rod, a connecting ring fixedly installed on the outer side of the bracket, and a nozzle fixedly installed on the outer side of the connecting ring, wherein the connecting ring and the gun barrel are rotatably connected.

[0005] As a preferred embodiment of this utility model, the barrel has a rotating groove inside, a locking rod is fixedly installed on the side of the connecting ring near the barrel, and a sealing ring is provided in the middle of the barrel and the connecting ring.

[0006] As a preferred embodiment of this utility model, a feed pipe is fixedly installed on the outside of the barrel, a fixing frame is fixedly installed inside the feed pipe, a telescopic rod is fixedly installed above the fixing frame, a spring is sleeved on the outside of the telescopic rod, a sealing plate is fixedly installed above the spring, a fixing ring is fixedly installed inside the feed pipe, and the sealing plate contacts the fixing ring.

[0007] As a preferred embodiment of this utility model, a fixing block is fixedly installed on the outer side of the gun barrel, a bracket two is fixedly installed on the outer side of the fixing block, a rotating shaft is rotatably connected inside the bracket two, and a roller is fixedly installed on the outer side of the rotating shaft.

[0008] As a preferred embodiment of this utility model, there are multiple clamping rods, all of which are cylindrical and located inside the sealing ring.

[0009] As a preferred embodiment of this utility model, there are two feed pipes, which are located on the upper and lower sides of the gun barrel respectively, and both feed pipes are connected to the gun barrel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a connecting rod fixedly installed on the left side of the output shaft, a bracket fixedly installed on the outside of the connecting rod, a connecting ring fixedly installed on the outside of the bracket, and a nozzle fixedly installed on the outside of the connecting ring. The connecting ring and the gun barrel are rotatably connected. When the adhesive and curing agent are injected into the gun barrel from the inside of the feed pipe, the motor is started and drives the spiral blade to rotate through the output shaft. At this time, the adhesive and curing agent are mixed inside the gun barrel and conveyed to the left by the spiral blade, so that the mixed material is injected into the inside of the connecting ring. As injection continues, the internal pressure of the connecting ring increases, the control valve is opened, and the connecting ring rotates with the output shaft through the bracket and the connecting rod, causing the nozzle to rotate to repair the inner wall of the pipe, improving the uniformity of adhesive injection and increasing the repair effect.

[0011] 2. This utility model features a spring sleeved on the outside of the telescopic rod, a sealing plate fixedly installed above the spring, and a fixing ring fixedly installed inside the feed pipe, with the sealing plate in contact with the fixing ring. The side of the feed pipe away from the barrel is connected to a circulation pump. When raw material needs to be injected into the barrel, the liquid material is first injected into the feed pipe through the circulation pump. At this time, the pressure inside the feed pipe increases, and the raw material will squeeze the sealing plate under the pressure, causing the telescopic rod and spring to contract. At this time, the sealing plate disengages from the fixing ring, thus facilitating the smooth entry of the raw material into the pipe. After injection, the spring provides elasticity to push the sealing plate towards the fixing ring, causing the sealing plate to reset, thereby preventing backflow due to excessive internal pressure in the barrel.

Detailed Implementation

[0014] 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.

[0015] like Figures 1 to 5 As shown, this utility model provides a pipe repair glue injection gun structure, including a pipe 1, a gun barrel 2 inside the pipe 1, a motor 3 fixedly installed on the left side of the gun barrel 2, an output shaft 4 fixedly installed on the output end of the motor 3, a spiral blade 5 fixedly installed on the outside of the output shaft 4, a connecting rod 6 fixedly installed on the left side of the output shaft 4, a bracket 7 fixedly installed on the outside of the connecting rod 6, a connecting ring 8 fixedly installed on the outside of the bracket 7, and a nozzle 9 fixedly installed on the outside of the connecting ring 8. The connecting ring 8 and the gun barrel 2 are rotatably connected.

[0016] After the adhesive and curing agent are injected into the gun barrel 2 from the inside of the feed pipe 13, the start motor 3 drives the spiral blade 5 to rotate through the output shaft 4. At this time, the adhesive and curing agent are mixed inside the gun barrel 2 and conveyed to the left by the spiral blade 5, so that the mixed material is injected into the inside of the connecting ring 8. After the injection continues, the internal pressure of the connecting ring 8 increases, the control valve is opened, and the connecting ring 8 will rotate with the output shaft 4 through the bracket 7 and the connecting rod 6, so that the nozzle 9 rotates to repair the inner wall of the pipe 1, improve the uniformity of the adhesive injection, and increase the repair effect.

[0017] The barrel 2 has a groove 10 inside, and a locking rod 11 is fixedly installed on the side of the connecting ring 8 near the barrel 2. A sealing ring 12 is provided in the middle of the barrel 2 and the connecting ring 8.

[0018] The lever 11 rotates inside the rotating groove 10, which keeps the connecting ring 8 stable during rotation. At the same time, the junction of the connecting ring 8 and the gun barrel 2 is sealed by the sealing ring 12 to prevent liquid leakage.

[0019] The barrel 2 is fixedly mounted with a feed pipe 13 on the outside, a fixed bracket 14 is fixedly mounted inside the feed pipe 13, a telescopic rod 15 is fixedly mounted above the fixed bracket 14, a spring 16 is sleeved on the outside of the telescopic rod 15, a sealing plate 17 is fixedly mounted above the spring 16, a fixing ring 18 is fixedly mounted inside the feed pipe 13, and the sealing plate 17 is in contact with the fixing ring 18.

[0020] The side of the feed pipe 13 away from the barrel 2 is connected to the circulation pump. When raw material needs to be injected into the barrel 2, the liquid material is first injected into the feed pipe 13 through the circulation pump. At this time, the pressure inside the feed pipe 13 increases, and the raw material will squeeze the sealing plate 17 under pressure, causing the telescopic rod 15 and spring 16 to contract. At this time, the sealing plate 17 is separated from the fixing ring 18, so that the raw material can smoothly enter the pipe 1. After the injection is completed, the spring 16 provides elastic force to push the sealing plate 17 towards the fixing ring 18, so that the sealing plate 17 is reset, thereby preventing the backflow due to excessive internal pressure in the barrel 2.

[0021] Among them, a fixing block 19 is fixedly installed on the outside of the barrel 2, a bracket 20 is fixedly installed on the outside of the fixing block 19, a rotating shaft 21 is rotatably connected inside the bracket 20, and a roller 22 is fixedly installed on the outside of the rotating shaft 21.

[0022] The fixing block 19 supports the gun barrel 2 through the bracket 20, so that the gun barrel 2 is always coaxial with the pipe 1. At the same time, the roller 22 is rotatably connected to the bracket 20 through the rotating shaft 21, so that the gun barrel 2 can be easily moved.

[0023] There are multiple locking rods 11, all of which are cylindrical and located inside the sealing ring 12.

[0024] Multiple levers 11 are rotatably connected to the rotating groove 10, so that the connecting ring 8 can be effectively kept stable when rotating.

[0025] There are two feed pipes 13, which are located on the upper and lower sides of the gun barrel 2 respectively, and both feed pipes 13 are connected to the gun barrel 2.

[0026] The main function of the two feed pipes 13 is to keep the raw materials separated before mixing, so as to prevent them from reacting quickly and solidifying after mixing.

[0027] Working principle and usage process of this utility model: First, a connecting rod 6 is fixedly installed on the left side of the output shaft 4. A bracket 7 is fixedly installed on the outside of the connecting rod 6. A connecting ring 8 is fixedly installed on the outside of the bracket 7. A nozzle 9 is fixedly installed on the outside of the connecting ring 8. The connecting ring 8 is rotatably connected to the gun barrel 2. When the adhesive and the curing agent are injected into the gun barrel 2 from the inside of the feed pipe 13, the motor 3 is started to drive the spiral blade 5 to rotate through the output shaft 4. At this time, the adhesive and the curing agent are mixed inside the gun barrel 2 and conveyed to the left by the spiral blade 5, so that the mixed material is injected into the inside of the connecting ring 8. As injection continues, the internal pressure of the connecting ring 8 increases, opening the control valve. The connecting ring 8 will rotate with the output shaft 4 via the bracket 7 and the connecting rod 6, causing the nozzle 9 to rotate and repair the inner wall of the pipe 1, improving the uniformity of the adhesive injection and increasing the repair effect. Finally, since the side of the feed pipe 13 furthest from the barrel 2 is connected to the circulation pump, when the raw material needs to be injected into the barrel 2, the liquid material is first injected into the feed pipe 13 through the circulation pump. At this time, the pressure inside the feed pipe 13 increases, and the raw material will squeeze the sealing plate 17 under the pressure, causing the telescopic rod 15 and the spring 16 to contract. At this time, the sealing plate 17 is separated from the fixing ring 18, so that the raw material can smoothly enter the interior of the pipe 1. After the injection is completed, the spring 16 provides elastic force to push the sealing plate 17 towards the fixing ring 18, so that the sealing plate 17 is reset, thereby preventing the backflow due to excessive internal pressure in the barrel 2.
