DETAILED DESCRIPTION
[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0020] See also Figure 1-Figure 5A subway pipeline connection auxiliary device comprises a base 1; an adjusting component is arranged on the base 1, the adjusting component is connected to two support frames 4, the support frames 4 are fixedly connected to a U-shaped frame 5, the adjusting component is used to adjust the spacing between the two U-shaped frames 5, the U-shaped frame 5 is provided with a positioning component for positioning the connected pipeline, a rotating ring 11 is rotatably arranged on one side of the base 1, a plurality of guide rods 12 distributed in an annular shape are installed on the rotating ring 11, the guide rods 12 are slidably connected to a movable rotating block 13, a plurality of grooves 18 distributed in an annular shape are opened in the movable rotating block 13, a second spring 14 connected to the rotating ring 11 is arranged in the groove 18.
[0021] The utility model fixes the pipeline by means of the positioning component, and the spacing between the two U-shaped frames 5 can be adjusted by the adjusting component, so that the two pipelines can be aligned and connected, thereby reducing the difficulty of pipeline alignment and facilitating the connection of the pipelines. The device reduces the difficulty of pipeline alignment and makes pipeline connection more convenient.
[0022] In one case of this embodiment, the adjusting component includes a bidirectional screw 2 rotatably arranged in the base 1, and both sides of the bidirectional screw 2 are threadedly connected to a movable frame 3 that is slidably connected to the inner wall of the base 1. The movable frame 3 is fixedly connected to the support frame 4. By rotating the bidirectional screw 2, the two movable frames 3 are driven to approach each other, and then the two U-shaped frames 5 are driven to move synchronously through the support frame 4, so that the pipes positioned by the positioning component are aligned and connected.
[0023] In one case of the present embodiment, a limit plate 15 is installed at one end of the bidirectional screw 2 that penetrates into the movable rotating block 13. The limit plate 15 can be used to limit the movable position of the movable rotating block 13. When the inner wall of the movable rotating block 13 contacts the limit plate 15, the side of the movable rotating block 13 close to the rotating ring 11 will fit with the rotating ring 11. The end of the bidirectional screw 2 close to the limit plate 15 is installed with symmetrically distributed clamping blocks 16. The inner wall of the movable rotating block 13 is provided with a plurality of annularly distributed clamping grooves 17. The clamping grooves 17 cooperate with the clamping blocks 16. When the movable rotating block 13 is pulled outward and the movable rotating block 13 is pulled to the limit plate 15, The slot 17 of the movable rotating block 13 will be inserted into the block 16 on the bidirectional screw 2. At this time, the movable rotating block 13 is rotated to drive the bidirectional screw 2 to rotate, thereby adjusting the distance between the two movable frames 3, that is, changing the distance between the two U-shaped frames 5, so that the pipes fixed by the positioning components on the U-shaped frames 5 are aligned and connected. When the movable rotating block 13 is released, under the action of the second spring 14, the movable rotating block 13 will contact the rotating ring 11 again. At this time, the slot 17 is separated from the block 16. At this time, the movable rotating block 13 is rotated, and the bidirectional screw 2 will not rotate, thereby preventing the bidirectional screw 2 from being accidentally touched by the outside world and causing it to rotate, and the use effect is better.
[0024] In one case of this embodiment, the positioning component includes a cylinder 6 installed at both ends of the U-shaped frame 5, the cylinder 6 is fixedly connected to the movable plate 7, and a clamping plate 10 is slidably arranged inside the movable plate 7. The pipeline is placed in the U-shaped frame 5, and the cylinder 6 is started. The cylinder 6 will drive the movable plate 7 to move, so that the clamping plate 10 clamps the pipeline to complete the positioning of the pipeline.
[0025] In one case of the present embodiment, a fixed rod 8 slidably connected to the clamp plate 10 is installed in the movable plate 7, and a first spring 9 connected to the clamp plate 10 is provided in the movable plate 7. The first spring 9 is sleeved on the fixed rod 8. When the two pipes are connected and aligned, the two U-shaped frames 5 will approach each other. After the two pipes are connected, the U-shaped frame 5 can continue to be moved. Under the action of the first spring 9, the two pipes can be subjected to elastic force, thereby avoiding excessive squeezing of the pipe connection due to the U-shaped frame 5 moving too close.
[0026] The working principle of the utility model is as follows: the pipeline is placed in the U-shaped frame 5, and the cylinder 6 is started. The cylinder 6 will drive the movable plate 7 to move, so that the clamping plate 10 clamps the pipeline to complete the positioning of the pipeline. When the movable rotating block 13 is pulled outward, when the movable rotating block 13 is pulled to the position of the limit plate 15, the clamping groove 17 of the movable rotating block 13 will be clamped into the clamping block 16 on the bidirectional screw 2. At this time, the movable rotating block 13 is rotated, and the bidirectional screw 2 can be driven to rotate, thereby adjusting the distance between the two movable frames 3, that is, changing the distance between the two U-shaped frames 5, so that the pipelines fixed by the positioning components on the U-shaped frame 5 are aligned and connected; when the two pipelines are connected and aligned, the two The U-shaped frames 5 will approach each other. When the two pipes are connected, the U-shaped frame 5 can continue to be moved. Under the action of the first spring 9, the two pipes can be subjected to elastic force, thereby avoiding excessive squeezing of the pipe connection due to the U-shaped frame 5 moving too close; when the movable rotating block 13 is released, under the action of the second spring 14, the movable rotating block 13 will contact the rotating ring 11 again, and the clamping groove 17 is separated from the clamping block 16. At this time, the movable rotating block 13 is rotated, and the bidirectional screw 2 will not rotate, thereby avoiding the external accidental contact with the bidirectional screw 2 to cause it to rotate, and the use effect is better. The device reduces the difficulty of pipe alignment and makes pipe connection more convenient.
[0027] The utility model fixes the pipeline by means of the positioning component, and the spacing between the two U-shaped frames 5 can be adjusted by the adjusting component, so that the two pipelines can be aligned and connected, thereby reducing the difficulty of pipeline alignment and facilitating the connection of the pipelines. The device reduces the difficulty of pipeline alignment and makes pipeline connection more convenient.
