Example

[0025] Reference Figure 1-4 , an auxiliary device for natural gas pipeline docking installation, comprising a base 100, and further comprising:

[0026] A sliding column 102, the sliding column 102 is fixedly connected to the inside of the base 100, a moving mechanism is slidably connected to the sliding column 102, and an output end of the moving mechanism is connected to a support plate 200;

[0027] The clamping mechanism is arranged on the side wall of the support plate 200. The clamping mechanism includes a driving component and a clamping component. The driving component and the clamping component cooperate with each other. The clamping mechanism is symmetrically arranged in two groups. The two groups of clamping mechanisms have the same structure, and one group of the clamping mechanisms is fixedly connected to the top of the base 100.

[0028] Among them, the clamping assembly includes a rotating frame 204, which is rotatably connected to the side wall of the support plate 200, and a limiting groove 205 is provided on the rotating frame 204. A toothed disc 206 is fixedly connected to the outer wall of the rotating frame 204, and a slide 207 is fixedly connected to the outer wall of the support plate 2. A slide rod 208 is slidably connected to the slide 207, and a matching column 209 is fixedly connected to the outer wall of the slide rod 208. The matching column 209 and the limiting groove 205 cooperate with each other, and a supporting roller 210 is connected to the clamping end of the slide rod 208. When in use, the two pipes are clamped and fixed respectively by the clamping assembly, and then the two pipes are driven to approach each other by the moving mechanism. Since the two sets of clamping mechanisms are on the same axis, the two pipes are also on the same axis. One of the pipes can be moved toward the other pipe to complete the docking operation of the two pipes.

[0029] Reference Figure 1-4 The driving assembly includes a driving shaft 201, which is rotatably connected to the side wall of the support plate 200. One end of the driving shaft 201 is connected to a driving gear 202, and the other end of the driving shaft 201 is connected to a crank 203. The driving gear 202 and the toothed disc 206 are meshed, and a limiting member 211 is arranged between the crank 203 and the support plate 200. When in use, the crank 203 is rotated to rotate the driving gear 202 through the driving shaft 201, and the driving gear 202 rotates the rotating frame 204 through the meshing toothed disc 206. The rotation of the rotating frame 204 causes the matching column 209 to drive the slide rod 208 to slide on the slide 207. During the sliding process of the slide 207, the supporting roller 210 has the function of centering, clamping and positioning the pipeline. The clamping mechanism can clamp and fix pipelines of different specifications, thereby improving its applicability. The limiting member 211 arranged in conjunction with the setting can limit the crank 203 to avoid loosening of the pipeline after clamping and fixing.

[0030] Reference Figure 1-2The moving mechanism includes a driving motor 103 connected to the side wall of the base 100 and a transmission screw 104 connected to the output end of the driving motor 103. The output end of the transmission screw 104 passes through the side wall of the base 100 and is connected to the inside thereof. A slider 105 is threadedly connected to the outer wall of the transmission screw 104. A slide groove 106 is provided on the top of the base 100. The support plate 200 is connected to the top of the slider 105, and the support plate 200 is slidably connected to the slide groove 106. When in use, the driving motor 103 is started to drive the transmission screw 104 connected to its output end to rotate, and the sliding column 102 and the slide groove 106 provided in combination can drive the slider 105 and the clamping mechanism to move along the slide groove 106, thereby driving one of the pipes to move toward the pipe to be docked to realize the docking operation.

[0031] Reference Figure 1-2 The four corner supports at the bottom of the base 100 are connected with a leveler, and the bottom of the leveler is connected with a universal wheel 101, which facilitates the movement of the device.

[0032] Specifically, when the auxiliary device for natural gas pipeline docking and installation is in use, the two sets of clamping mechanisms are first moved to the positions of the two pipelines respectively, and the pipelines are located at the center positions of the clamping mechanisms. Then, the crank 203 is turned to rotate the driving gear 202 through the driving shaft 201, and the driving gear 202 rotates the rotating frame 204 through the meshing toothed disc 206. The rotation of the rotating frame 204 causes the matching column 209 to drive the slide bar 208 to slide on the slide 207. During the sliding process of the slide 207, the supporting roller 210 performs the function of centering and clamping the pipeline. Then, the driving motor 13 drives the transmission screw 104 connected to its output end to rotate, and the matching slide column 102 and the slide groove 106 can drive the slider 105 and the clamping mechanism to move along the slide groove 106. Since the two sets of clamping mechanisms are on the same axis, the two pipelines are also on the same axis. Therefore, when one pipeline is moved by the moving mechanism, the two pipelines can be docked, and the operation is simple and easy to use.
