[0023] Please see Figure 1-3 This utility model provides a technical solution: a welding auxiliary device for connecting cable protection pipes, comprising:

[0024] The first protective tube 1 is installed in multiple limit blocks 2;

[0025] Auxiliary mechanism 3, mounted on the first protective pipe 1, includes a mounting component, multiple sets of connecting components, multiple connecting rods 301, and multiple connecting holes 302. The mounting component is mounted on the first protective pipe 1. Each set of connecting components is equidistantly positioned on the mounting component along the circumferential direction. Each connecting rod 301 is mounted on a connecting component and slides through the inner wall of a connecting hole 302. Each connecting hole 302 is located on the mounting component.

[0026] The second protective tube 4 is installed on the mounting component. Multiple limiting grooves 5 are equidistantly provided on one side of the outer wall of the second protective tube 4 along the circumferential direction. Each limiting block 2 is slidably embedded in the inner wall of the limiting groove 5.

[0027] In this implementation scheme: each limiting block 2 is fixedly and equidistantly disposed on one side of the outer wall of the first protective pipe 1 along the circumferential direction. Through the sliding cooperation between the limiting block 2 on the first protective pipe 1 and the limiting groove 5 on the second protective pipe 4, the connection between the first protective pipe 1 and the second protective pipe 4 can be aligned to prevent misalignment of the connection during welding, which would affect the welding quality. Through the auxiliary mechanism 3, the cable protection pipe bodies can be connected and fixed together to avoid errors that may occur during welding, resulting in an unstable connection. Through the connecting component on the mounting component, the connecting rod 301 can pass through the connecting hole 302 to connect and fix the two cable protection pipe bodies together to prevent misalignment of the cable protection pipe bodies during welding, which would result in an unstable connection.

[0028] Specifically, the installation components include an installation pipe 303, a connecting pipe 304, and an installation assembly. The installation pipe 303 is installed on the outer wall of the first protective pipe 1, the connecting pipe 304 is installed on one side of the outer wall of the second protective pipe 4, and the installation assembly is located on the installation pipe 303.

[0029] In this embodiment: the mounting tube 303 is movably sleeved on the outer wall of the first protective tube 1 and is installed on the first protective tube 1 by bolts; the connecting tube 304 is movably sleeved on the outer wall of the second protective tube 4 and is installed on the second protective tube 4 by bolts; the mounting assembly is used for the installation and placement of the connecting hole 302 and the connecting rod 301.

[0030] Specifically, the mounting components include a movable ring 305 and a fixed ring 306. The movable ring 305 is movably fitted onto the outer wall of the mounting tube 303, and the fixed ring 306 is fixedly fitted onto the outer wall of the connecting tube 304. Each connecting hole 302 is equidistantly opened on one side of the outer wall of the fixed ring 306 along the circumferential direction.

[0031] In this embodiment, a groove is provided on the outer wall of the movable ring 305. The movable ring 305 is slidably embedded in the inner wall of the groove. As the movable ring 305 rotates, the position of each connecting rod 301 can be changed to prevent the position of the connecting rod 301 from being fixed and thus preventing the welding between the cable protection pipe bodies from being fully completed.

[0032] Specifically, each set of connecting components includes a mounting cylinder 307, a first spring 308, and a fixing assembly. The mounting cylinder 307 is fixedly disposed on one side of the outer wall of the movable ring 305.

Each connecting rod 301 is slidably embedded in one side of the outer wall of the mounting cylinder 307, and each connecting rod 301 slidably passes through one side of the outer wall of the movable ring 305.

[0033] In this embodiment: the mounting cylinder 307 is used for the installation and placement of the connecting rod 301. The outer wall of the connecting rod 301 is fixedly connected to the first spring 308. The first spring 308 is sleeved on the outer wall of the connecting rod 301. Through the first spring 308 in the mounting cylinder 307, the connecting rod 301 can enter the connecting hole 302, so that the cable protection pipe bodies are connected together. The position of the connecting rod 301 is fixed by the fixing component to prevent the cable protection pipe bodies from being separated, which would affect the stability of the welding at the connection of the cable protection pipe bodies.

[0034] Specifically, each set of fixing components includes a mounting bracket 309, a fixing rod 310, a second spring 311, and a fixing hole 312.

The second spring 311 is fixedly disposed on the top of the inner wall of the mounting bracket 309 and is sleeved on the outer wall of the fixing rod 310. The fixing hole 312 is opened at the top of the outer wall of the connecting rod 301, and the fixing rod 310 slides through the inner wall of the fixing hole 312.

[0035] In this embodiment: the mounting bracket 309 is used for the installation and placement of the fixing rod 310. The second spring 311 is fixedly installed between the mounting bracket 309 and the fixing rod 310. The second spring 311 enables the fixing rod 310 to enter the fixing hole 312 to prevent the cable protection tube body from separating during the welding process.

[0036] Specifically, guide frames 6 are fixedly provided at equal intervals along the circumferential direction on one side of the outer wall of the fixing ring 306, and each fixing rod 310 slides through the inner wall of the guide frame 6.

[0037] In this embodiment, the guide frame 6 guides the movement of the fixed rod 310.

[0038] In use, first install the mounting tube 303 on the first protective tube 1, then install the connecting tube 304 on the second protective tube 4. Next, slide the limiting block 2 on the first protective tube 1 and the limiting groove 5 on the second protective tube 4 to align the connection between the first protective tube 1 and the second protective tube 4. Then, pull each fixing rod 310 upward in sequence to prevent the fixing rod 310 from blocking the connecting hole 302. Under the action of the first spring 308, the connecting rod 301 can enter the connecting hole 302. Then, release the fixing rod 310, and under the action of the second spring 311, it can enter the fixing hole 312 on the connecting rod 301 to fix the position of the connecting rod 301. This can connect and fix the cable protection tubes together, avoiding errors that may occur during the welding process, which could lead to an unstable connection.
