Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically a trenchless pipeline repair device. Background Technology

[0002] Pipeline repair refers to restoring the normal function of damaged or leaking pipelines through technical means. It is mainly divided into two categories: external anti-corrosion layer repair and internal repair. Pipeline repair technology is transforming from traditional excavation to trenchless repair. Technologies such as ultraviolet curing and pipe crushing have become mainstream due to their environmental protection and high efficiency.

[0003] In response to the above and existing related technologies, pipeline repair work often requires the use of pipeline robots equipped with various repair tools. However, since most pipeline robots lack limiting mechanisms, operational errors can easily occur during their use, leading to the pipeline robot tipping over and affecting the repair work. Therefore, this paper proposes a trenchless pipeline repair device to address these issues. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A trenchless pipe repair device of this utility model includes a robot and a support device. A camera is fixedly connected to the side wall of the robot, and two support wheels are rotatably connected to both sides of the robot. A connector is fixedly connected to the end of the robot surface away from the camera. The support device is provided on the upper surface of the robot. The support device includes a support block, the bottom end of which is fixedly connected to the upper surface of the robot. Two sleeve rods are fixedly connected to the surface of the support block. Threaded rods are threaded to the inner walls of the sleeve rods. A roller assembly is rotatably connected to the upper surface of the threaded rods. A quick-locking airbag is provided on the surface of the connector. The threaded rods drive the roller assembly to move. After the roller assembly extends to a suitable length, the robot moves inside the pipe, and the roller assembly presses against the inner surface of the pipe. By setting up the support block, sleeve rods, threaded rods, and roller assembly, the possibility of the robot tipping over can be reduced.

[0006] Preferably, a knob is fixedly connected to the surface of the threaded rod. When it is necessary to operate the threaded rod, the knob is pushed to make the knob drive the threaded rod to rotate. The threaded rod can be easily operated by setting the knob.

[0007] Preferably, the surface of the sleeve rod is provided with a threaded groove, and the surface of the threaded rod and the inner surface of the threaded groove of the sleeve rod are threadedly connected. When the threaded rod rotates, the threaded rod rotates on the inner wall of the threaded groove. The opening of the threaded groove facilitates the rotation of the threaded rod on the inner surface of the sleeve rod.

[0008] Preferably, the bottom end of the roller assembly is fixedly connected to two support rods, and the surfaces of the two support rods are fixedly connected to limit rings. The limit rings are sleeved on the surface of the sleeve rods, and the support rods drive the limit rings to slide. The limit rings slide on the surface of the sleeve rods. By setting the support rods and limit rings, the roller assembly can be supported to a certain extent.

[0009] Preferably, two limiting rods are fixedly connected to the surface of the sleeve rod, and the surface of the limiting rod is slidably connected to the inner surface of the limiting ring. When the limiting ring slides, the limiting ring slides on the surface of the limiting rod, and the limiting rod can limit the position of the limiting ring.

[0010] Preferably, the surface of the support wheel is provided with an anti-slip device, which includes a rubber sleeve that is fitted over the surface of the support wheel. A limit post is fixedly connected to the side wall of the support wheel, and a threaded disc is threadedly connected to the surface of the limit post. The threaded disc is located on one side of the rubber sleeve. Rotating the threaded disc causes it to rotate on the surface of the limit post, and the threaded disc will rotate to the side wall of the rubber sleeve. By setting the rubber sleeve, the limit post, and the threaded disc, the slippage of the support wheel can be reduced.

[0011] Preferably, the surface of the rubber sleeve is fixedly connected with multiple anti-slip strips, and the surface of the threaded disc is fixedly connected with multiple protrusions. When the rubber sleeve rotates, the rubber sleeve will drive the anti-slip strips to rotate. By setting the anti-slip strips, the anti-slip ability of the rubber sleeve can be increased.

[0012] The advantages of this utility model are:

[0013] 1. When the robot needs to be used, the sleeve is fixed on the support block. Then, the knob is turned to make the knob drive the threaded rod to rotate. The threaded rod rotates on the side wall of the roller assembly and the inner wall of the threaded groove of the sleeve. The threaded rod drives the roller assembly to move. The roller assembly drives the support rod to slide. The support rod drives the limit ring to slide. The limit ring slides on the surface of the limit rod. After the roller assembly moves to the appropriate position, the knob is stopped. When the robot moves, the robot will drive the roller assembly to move. The rollers on the roller assembly roll on the inner surface of the pipe. By setting up the entire device, the robot can be supported, reducing the possibility of the robot tipping over, thereby reducing the possibility of affecting the repair efficiency.

[0014] 2. When using the robot, the rubber sleeve is placed on the surface of the support wheel, and then the threaded disc is rotated to the surface of the limiting post. The threaded disc is pressed against the side wall of the rubber sleeve. When operating the threaded disc, the palm will press on the protrusion. When the support wheel rotates, the support wheel drives the anti-slip strip to rotate. The anti-slip strip moves on the inner surface of the pipe. By setting up the whole device, the anti-slip ability of the support wheel can be increased and the slippage of the support wheel in the pipe can be reduced. Attached Figure Description

The surface of the connector 6 is provided with a quick-lock special airbag. During operation, the sleeve rod 42 is fixed on the support block 41, and then the threaded rod 43 is rotated to make the threaded rod 43 rotate on the inner wall of the sleeve rod 42. The threaded rod 43 drives the roller assembly 44 to move. After the roller assembly 44 extends to a suitable length, the robot 1 moves in the pipe. The roller assembly 44 will press against the inner surface of the pipe. By setting the support block 41, sleeve rod 42, threaded rod 43 and roller assembly 44, the possibility of the robot 1 tipping over can be reduced.

[0024] A knob 45 is fixedly connected to the surface of the threaded rod 43; during operation, pushing the knob 45 causes the threaded rod 43 to rotate, and the knob 45 facilitates the operation of the threaded rod 43.

[0025] The surface of the sleeve rod 42 is provided with a threaded groove 46, and the surface of the threaded rod 43 is threadedly connected to the inner surface of the threaded groove 46 of the sleeve rod 42. During operation, the threaded rod 43 rotates on the inner wall of the threaded groove 46, and the opening of the threaded groove 46 facilitates the rotation of the threaded rod 43 on the inner surface of the sleeve rod 42.

[0026] Two support rods 47 are fixedly connected to the bottom end of the roller assembly 44. Limiting rings 48 are fixedly connected to the surfaces of the two support rods 47, and the limiting rings 48 are sleeved on the surface of the sleeve rod 42. During operation, the roller assembly 44 will drive the support rods 47 to move, and the support rods 47 will drive the limiting rings 48 to slide. The limiting rings 48 slide on the surface of the sleeve rod 42. By setting the support rods 47 and the limiting rings 48, the roller assembly 44 can be supported to a certain extent.

[0027] Two limiting rods 49 are fixedly connected to the surface of the sleeve rod 42. The surface of the limiting rod 49 is slidably connected to the inner surface of the limiting ring 48. During operation, the limiting ring 48 slides on the surface of the limiting rod 49, and the limiting rod 49 can limit the position of the limiting ring 48.
