Description

Technical Field

[0001] The utility model relates to the field of positioning and calibration for trenchless pipeline laying, in particular to a positioning and calibration device for trenchless pipeline laying. Background Art

[0002] During the trenchless pipe laying process, the pipeline needs to be positioned and calibrated to ensure that the installed part is consistent with the overall pipeline network.

[0003] When the pipeline is relatively small and light, it is lifted manually. Manual calibration and alignment will produce relatively large errors, and there will be certain safety hazards when personnel go down into the tunnel. When the pipe diameter is large and the pipe body is heavy, a crane or a simple bracket with a small lifting mechanism is usually used. The two ends of the pipe are tied with two ropes, and the lifting position is adjusted by the lifting equipment. When the pipeline drops to a certain angle, one or more personnel are required to manually adjust it from below because the rope is easy to swing. First of all, this operation method uses a lifting rope, so the accuracy is not high, and the positioning is difficult and requires manual assistance. The assistants face certain safety risks under the heavy pipe lifting. In addition, the pipe diameters are diverse, and the clamping tools or ropes used cannot adapt to a large range of pipe diameter changes. In summary, a water pipe support device for water conservancy projects is needed. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that when trenchless pipelines are laid, the positioning accuracy of the traditional pipe laying method is not high, so that the installation quality of the pipelines cannot be guaranteed.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a positioning and calibration device for trenchless pipeline laying, comprising a base, and a bearing end is connected to the lower part of the base.

[0008] A support frame is connected downwardly to the top of the base, and an auxiliary frame is connected below the support frame. A V-shaped telescopic rod one and a V-shaped telescopic rod two are rotatably connected between the edges of the support frame and the auxiliary frame. A telescopic frame is connected below the auxiliary frame, and a V-shaped telescopic rod three and a V-shaped telescopic rod four are rotatably connected between the telescopic frame and the edge of the auxiliary frame. The V-shaped telescopic rod three is arranged below the V-shaped telescopic rod one, and the V-shaped telescopic rod four is arranged below the V-shaped telescopic rod two.

Adjusting rods are rotatably connected between the two ends of the driving block and the clamping rod, and the load-bearing end is arranged at the bottom end of the clamping rod.

[0009] Furthermore, a support rod is connected downwardly to the top of the base, and an electric telescopic rod is rotatably connected between the bottom end of the support rod and the top of the V-shaped telescopic rod to provide power support for each V-shaped telescopic rod to drive the telescopic frame to move up and down under the base.

[0010] Furthermore, a second electric telescopic rod is connected downwardly to the top of the support, and the movable end of the second electric telescopic rod is matched with a driving block to provide power for the clamping rods on both sides of the support to carry the load-bearing end to rotate to a certain extent.

[0011] Furthermore, the auxiliary frame edge is connected with a plurality of support blocks respectively matched with the V-shaped telescopic rod 1, the V-shaped telescopic rod 2, the V-shaped telescopic rod 3 and the V-shaped telescopic rod 4, so as to facilitate the reasonable connection between the above components.

[0012] Furthermore, a gear transmission mechanism is commonly connected between the bottom end of the V-shaped telescopic rod 1 and the top end of the V-shaped telescopic rod 3, so that when the V-shaped telescopic rod 1 rotates relative to the auxiliary frame, the V-shaped telescopic rod 3 below can also be driven to perform a corresponding rotation movement, thereby further driving the telescopic frame below to continue to descend and extend under the auxiliary frame.

[0013] 3. Beneficial Effects

[0014] The advantages of the utility model compared with the prior art are: firstly, the device is provided with a simple lifting mechanism, which can replace manual labor to position and lay trenchless pipelines at a low cost. Due to its relatively simple structure, it can be reasonably designed and ordered according to construction needs and the objective environment on site.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] The device for positioning and calibrating the pipeline is placed on the ground through the base 1 , and the pipeline to be laid is supported through the bearing end 18 .

[0025] Embodiment 2

[0026] Combined with Figure 1-5, the top of the base 1 is connected downwardly with a support frame 2, and the bottom of the support frame 2 is connected with an auxiliary frame 7, and a V-shaped telescopic rod 3 and a V-shaped telescopic rod 2 6 are rotatably connected between the edges of the support frame 2 and the auxiliary frame 7, and a support rod 4 is connected downwardly from the top of the base 1, and an electric telescopic rod 5 is rotatably connected between the bottom end of the support rod 4 and the top of the V-shaped telescopic rod, which provides power support for each V-shaped telescopic rod to drive the telescopic frame 12 to move up and down below the base 1, and a telescopic frame 12 is connected below the auxiliary frame 7, and a V-shaped telescopic rod three 10 and a V-shaped telescopic rod four 11 are rotatably connected between the telescopic frame 12 and the edge of the auxiliary frame 7, and the V-shaped telescopic rod three 10 is arranged below the V-shaped telescopic rod one 3, and the V-shaped telescopic rod four 11 is arranged below the V-shaped telescopic rod two 6, and a plurality of support rods are connected to the edge of the auxiliary frame 7, which respectively cooperate with the V-shaped telescopic rod one 3, the V-shaped telescopic rod two 6, the V-shaped telescopic rod three 10 and the V-shaped telescopic rod four 11. The support block 8 is convenient for the reasonable connection between the above-mentioned components. A gear transmission mechanism 9 is commonly connected between the bottom end of the V-shaped telescopic rod 13 and the top end of the V-shaped telescopic rod 3 10, so that when the V-shaped telescopic rod 13 rotates relative to the auxiliary frame 7, the V-shaped telescopic rod 3 10 below can also be driven to perform corresponding rotation movements, thereby further driving the telescopic frame 12 below to continue to descend and extend under the auxiliary frame 7. A support 13 is connected inside the telescopic frame 12, and a clamping rod 15 is rotatably connected to both sides of the support 13. A driving block 16 is connected below the support 13. An electric telescopic rod 2 14 is downwardly connected to the top end of the support 13. The moving end of the electric telescopic rod 2 14 is matched with the driving block 16 to provide power for the clamping rods 15 on both sides of the support 13 to carry the load-bearing end 18 to rotate to a certain extent. An adjusting rod 17 is commonly rotatably connected between the two ends of the driving block 16 and the clamping rod 15, and the load-bearing end 18 is located at the bottom end of the clamping rod 15.

[0027] A telescopic structure is formed by V-shaped telescopic rod 1 3, V-shaped telescopic rod 2 6, V-shaped telescopic rod 3 10 and V-shaped telescopic rod 4 11, and a lifting mechanism is formed in cooperation with an auxiliary frame 7, a support frame 2 and a telescopic frame 12, wherein an electric telescopic rod 1 5 provides a control output for the lifting mechanism, and a clamping mechanism is provided under the lifting mechanism. Through two clamping rods 15 that are clamped or loosened to each other, the load-bearing end 18 is driven to rotate to a certain extent, so that the pipeline can be lifted. The clamping mechanism is provided with a control output by an electric telescopic rod 2 14, and completes the clamping with the cooperation of components such as a driving block 16 and an adjusting rod 17.

[0028] In the specific implementation of the utility model, when the device is used to calibrate and position the trenchless pipeline laying, the base 1 of the device is partially placed above the pipe groove, and the clamping mechanism picks up the pipe through the control of the electric telescopic rod 14. The pipeline pre-placement step before picking up and the mechanism and equipment used in this step are not within the scope of the key points to be improved in this application, and they all belong to mature existing technologies. No further details are given here. The device holding the pipeline, under the action of the top electric telescopic rod 5, controls the lifting mechanism to move the clamping end and the pipeline downward, slowly extend them into the pipe groove, and stop after reaching a suitable position consistent with the pipeline, thereby completing the calibration and positioning. During the calibration and positioning, the position of the pipeline can be adjusted by observation. After a series of subsequent welding fixation or pre-embedded treatment steps, the device runs in the direction to remove the pipeline and raise the clamping mechanism back to the initial position.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
