DETAILED DESCRIPTION

[0024] The technical scheme of the patent will be further described in detail in combination with specific embodiments.

[0025] Please refer to Figs. 1-3 A kind of grain depot construction underground pipeline laying auxiliary device, including connecting plate 1, the number of connecting plate 1 is set to two, the bottom of connecting plate 1 is installed with fixed rod 2, the bottom of fixed rod 2 is installed with bottom plate 3, still include:

[0026] Arc-shaped supporting plate 4 installed on bottom plate 3, the top of arc-shaped supporting plate 4 is arc-shaped;

[0027] Clamping plate 5, the bottom of clamping plate 5 is arc-shaped;

[0028] Driving mechanism, the driving mechanism is arranged on connecting plate 1 and is connected with clamping plate 5, for driving clamping plate 5 moves and cooperates arc-shaped supporting plate 4 to pipe clamping and fixing;

[0029] First electromagnet 17 arranged at the top of arc-shaped supporting plate 4, the bottom of clamping plate 5 is provided with second electromagnet 18;

[0030] Control frame 9 installed on the top of clamping plate 5;

[0031] Control mechanism, the control mechanism is arranged in control frame 9, for controlling first electromagnet 17 and second electromagnet 18;

[0032] Touch mechanism, the touch mechanism is arranged on clamping plate 5, for starting control mechanism;

[0033] A connecting rope 23 is provided on the connecting plate 1, and the connecting rope 23 is connected to an adjustment mechanism for adjusting the distance between the two connecting plates 1.

[0034] By connecting the lifting equipment to the fixed frame 19, the fixed frame 19 is lifted to the location of the pipe to be laid. The spacing between the arc-shaped support plates 4 and the clamping plates 5 on both sides can be adjusted by the adjustment mechanism, thus adapting to the lifting operations of pipes of different lengths. The arc-shaped support plates 4 are inserted into the inside of the pipe, while the clamping plates 5 are located on the outside of the pipe. Then, driven by the drive mechanism, the clamping plates 5 and the arc-shaped support plates 4 gradually move closer, thereby clamping both ends of the pipe. During the clamping process, the trigger mechanism activates the control mechanism, causing the first electromagnet 17 and the second electromagnet 18 to be energized and generate magnetism, making them tightly attracted to the inner and outer walls of the pipe, making the clamping more stable. This avoids the problem of the pipe falling off during the lifting and laying process, improving the safety of pipe lifting.

[0035] In one embodiment, the actuation mechanism includes a slide rod 13 slidably disposed in the middle of the clamping plate 5 and with its top extending into the control frame 9. An actuation rod 8 is installed at the bottom of the slide rod 13, and a slide plate 14 is installed at the top of the slide rod 13. The slide plate 14 is connected to the bottom wall of the control frame 9 by a second spring 24. The control mechanism includes an inner cavity 10 formed at the top of the control frame 9. A limit plate 11 is slidably disposed in the inner cavity 10. The limit plate 11 is connected to the inner cavity 10 by a first spring 12. A conductive block 15 is installed on the side of the limit plate 11 near the slide plate 14, and a conductive slider 16 is installed on the side of the slide plate 14 near the limit plate 11. The conductive block 15, the conductive slider 16, the first electromagnet 17, and the second electromagnet 18 are electrically connected.

[0036] During the process of the drive mechanism driving the clamping plate 5 to approach the arc-shaped support plate 4 so that it cooperates with the arc-shaped support plate 4 to clamp and fix the end of the pipe, the pipe will push the trigger rod 8, which will push the slide rod 13 to make the slide plate 14 slide towards the side of the limit plate 11 within the control frame 9, and make the slide plate 14 contact the limit plate 11, so that the conductive slider 16 on the slide plate 14 contacts the conductive block 15 on the limit plate 11. At this time, the first electromagnet 17 and the second electromagnet 18 are energized to generate magnetism, so that the generated magnetism forms a magnetic attraction to the pipe. Thus, after the clamping plate 5 and the arc-shaped support plate 4 clamp the end of the pipe, the magnetism makes the clamping plate 5 and the arc-shaped support plate 4 tightly attracted to the pipe, thereby making the clamping more stable and avoiding the problem of the pipe falling off during the pipe hoisting to the laying area, thus improving the safety of pipe hoisting.

[0037] Wherein, in the embodiment, the elastic pulling force of the second spring 24 makes the slide plate 14 be pulled to one side of the clamp plate 5, so that the trigger rod 8 protrudes from the arc surface of the bottom of the clamp plate 5 in the normal state, and the elastic pushing force of the first spring 12 makes the limiting plate 11 be pushed, so that the limiting plate 11 and the slide plate 14 can be in good contact, the conductive block 15 and the conductive slide block 16 are in stable contact, and the first electromagnet 17 and the second electromagnet 18 are prevented from being powered off due to disconnection.

[0038] In one case of the embodiment, the driving mechanism comprises a hydraulic rod 7 connected to the bottom of the connecting plate 1, the bottom of the hydraulic rod 7 is provided with a lifting plate 6 in sliding connection with the fixed rod 2, and the lifting plate 6 is fixedly connected with the clamp plate 5.

[0039] The hydraulic rod 7 is started by the controller, so that the hydraulic rod 7 drives the lifting plate 6 to slide along the fixed rod 2 to one side of the bottom plate 3, thereby driving the clamp plate 5 to move to one side of the arc-shaped supporting plate 4, so that the clamp plate 5 clamps the outer wall of the pipeline, and the arc-shaped supporting plate 4 clamps the inner wall of the pipeline.

[0040] In one case of the embodiment, the adjusting mechanism comprises a fixed frame 19, a bidirectional screw rod 20 is rotatably arranged in the fixed frame 19, movable frames 21 in sliding connection with the inner wall of the fixed frame 19 are threadedly connected to the two sides of the bidirectional screw rod 20, the movable frames 21 are connected with connecting ropes 23, and the end of the fixed frame 19 is provided with a motor 22 connected with the bidirectional screw rod 20.

[0041] The motor 22 is started by the controller, so that the motor 22 drives the bidirectional screw rod 20 to rotate, thereby driving the two movable frames 21 to move, and the interval between the two clamp plates 5 and the arc-shaped supporting plates 4 can be adjusted by the connecting ropes 23, so that the hoisting and laying operation of the pipeline of different lengths can be adapted.

[0042] The working principle of the utility model is: the hoisting device is connected with the fixed frame 19, the fixed frame 19 is hoisted to the position of the pipeline to be laid by the hoisting device, the interval between the arc-shaped supporting plates 4 and the clamp plates 5 on both sides can be adjusted by the adjusting mechanism, so that the hoisting operation of the pipeline of different lengths can be adapted, the arc-shaped supporting plates 4 are clamped into the inside of the pipeline, the clamp plates 5 are located outside the pipeline, then the clamp plates 5 and the arc-shaped supporting plates 4 gradually approach under the driving of the driving mechanism, so that the two ends of the pipeline are clamped, and in the clamping process, the trigger mechanism starts the control mechanism, the first electromagnet 17 and the second electromagnet 18 are electrified to generate magnetism, and are tightly adsorbed on the inner wall and the outer wall of the pipeline, so that the clamping is more stable, and the problem that the pipeline falls off in the process of hoisting to the laying area is avoided, and the safety of the pipeline hoisting is improved.
