[0002] my country is a major rail transport country, handling a large volume of passenger and freight traffic. Building railway tunnels is a key way to shorten lines, reduce slopes, improve operating conditions, and increase traction capacity. However, internal tunnel drainage systems have always been a weak link in tunnel design and construction.

[0003] In karst areas or areas where the water is rich in mineral elements such as potassium and calcium, tunnel drainage pipes can become clogged due to the crystallization and precipitation of mineral salts, gradually losing their drainage capacity. If this problem is not addressed promptly, it can lead to a series of engineering problems such as lining cracking, large-scale water leakage, and steel corrosion, posing a serious threat to railway tunnel structures and train operation safety.

[0004] However, the drill bit of the pipe cleaning machine in the prior art has no support, which causes the drill bit to be unstable during operation and easily damages the pipe wall, causing the pipe to rupture. Therefore, there are certain limitations. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Based on the problem that the drill bit of the existing existing pipe dredging machine has no support, which leads to the problem that the drill bit is unstable and easily damages the pipe wall during operation, this embodiment provides a new type of pipe dredging support device, please refer to Figure 1-Figure 3 The present embodiment provides a novel pipe dredging support device capable of supporting a drill bit, enabling it to dredge and clean the inner wall of a pipe. The novel pipe dredging support device includes a concealed pipe 1, within which is disposed a dredging support mechanism 2 for dredging and cleaning the interior of the concealed pipe 1. The dredging support mechanism 2 provides support for the drill bit, improving the stability of the drill bit fixture and preventing the drill bit from damaging the inner wall of the pipe. Furthermore, the monitoring component 204 provides full monitoring of the pipeline dredging process.

[0027] Because the drill bit of conventional pipe dredging machines lacks support, making it unstable and prone to damaging the pipe wall during operation, the device is equipped with a dredging support mechanism 2. The dredging support mechanism 2 includes an axial positioning block 201, one side of which is mounted a roller mounting bracket 202. A guide roller 203 is rotatably connected to the roller mounting bracket 202 via an axle pin, and the guide roller 203 is in contact with the wall of the concealed pipe 1. The axial positioning block 201 is equipped with a monitoring component 204 for real-time monitoring of the dredging status. The axial positioning block 201 and the roller mounting bracket 202 are manufactured by at least one of machining, welding, or integrated additive manufacturing. The guide roller 203 is made of a highly wear-resistant rubber material. The guide roller 203 moves by fitting against the inner wall of the concealed pipe 1 to provide support for the drill bit, thereby preventing the drill bit from being unstable and causing damage to the inner wall of the pipe during the dredging process. The rubber guide roller 203 has higher wear resistance and higher friction, making it more convenient to move in the pipe. The integrally formed axial positioning block 201 and roller fixing frame 202 prevent stress concentration during use, thereby reducing the service life of the device.

[0028] Because the device performs dredging on the inner wall of the pipe, workers cannot visually observe the dredging status of the concealed pipe 1. Therefore, the device is also provided with a monitoring assembly 204. The monitoring assembly 204 includes a camera mounting block 2041 mounted on the axial positioning block 201. An industrial camera 2042 is mounted in a hole defined in the camera mounting block 2041. An O-ring 2043 is sleeved around the outside of the industrial camera 2042 and the axial positioning block 201. The dredging support mechanism 2 is composed of three axial positioning blocks 201 and three camera mounting blocks 2041 arranged in a staggered circular pattern, with O-rings 2043 sleeved around the outside of the two. The industrial camera 2042, mounted in the hole of the camera mounting block 2041, monitors the dredging status of the concealed pipe 1 in real time. The O-ring 2043 secures the industrial camera 2042 and circumferentially secures the entire device.

[0029] Example 2

[0030] On the basis of Example 1, Figure 1-Figure 3 As shown, in order to make the device move more stably on the inner wall of the concealed tube 1, the device is equipped with roller bearings 301 in the three axial positioning blocks 201 and the three camera mounting blocks 2041. A soft shaft 302 is sleeved inside the roller bearing 301. When the guide roller 203 moves in contact with the inner wall of the concealed tube 1, the device as a whole also moves forward and backward on the inner wall of the concealed tube 1 with the soft shaft 302 sleeved inside it, playing a guiding role and further improving the stability of the movement.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
