[0002] In order to measure and locate the pipeline route buried underground, a pipeline measurement and positioning device consisting of a measuring component and a driven wheel is usually used for measurement. The measuring component is used to measure and locate the position of the pipeline, and the driven wheel is used to abut the inner wall of the pipeline to improve the stability of the movement of the measuring component.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] It is understandable that, referring to Figures 1 to 4The utility model is an adjustable pipeline measurement and positioning device, comprising a positioning mechanism 100 and an adjusting mechanism 200. The positioning mechanism 100 comprises an installation bin 110, a measuring assembly 120 and a moving assembly 130. The measuring assembly 120 is arranged in the installation bin 110. The measuring assembly 120 is used to measure the position of the positioning pipeline. The moving assembly 130 is used to drive the installation bin 110 to move. The adjusting mechanism 200 comprises two installation plates 210 and four sets of telescopic assemblies 220. The two installation plates 210 are respectively arranged at the front and rear sides of the installation bin 110. Each installation plate 210 is provided with two sets of telescopic assemblies 220, and the two installation plates 210 are respectively provided with two sets of telescopic assemblies 220. The telescopic assembly 220 is respectively located on the left and right sides of the mounting bin 110, and the telescopic assembly 220 includes a driven wheel 221, a first driving member 222 and an elastic member 223. The driven wheel 221 is rotatably connected to the movable end of the first driving member 222. The first driving member 222 is used to drive the driven wheel 221 to move so that the two driven wheels 221 on the same mounting plate 210 move closer to or away from each other. The fixed end of the first driving member 222 is movably connected to the mounting plate 210, one end of the elastic member 223 is connected to the mounting plate 210, and the other end of the elastic member 223 is connected to the fixed end of the first driving member 222.

[0029] During measurement and positioning, the adjustable pipeline measurement and positioning device is placed in the pipeline, and the first driving member 222 drives the driven wheel 221 to move, so that the two driven wheels 221 on the same mounting plate 210 move closer to or away from each other, so as to adjust the extension diameter between the two driven wheels 221, so that the driven wheel 221 abuts against the inner wall of the pipeline, and the movement of the mounting chamber 110 can drive the driven wheel 221 to roll along the inner wall of the pipeline, so as to guide the mounting chamber 110 to move along the axial direction of the pipeline, and the mounting chamber 110 is driven to move in the pipeline by the moving assembly 130, thereby driving the measuring assembly 120 to move, and the measuring assembly 120 measures and positions the position of the pipeline during the movement, and the extension diameter between the two driven wheels 221 is adjusted by the first driving member 222, so as to be able to adapt to the measurement of the pipeline. The measurement and positioning of pipes with different inner diameters can be improved to improve versatility. In addition, when the measuring component 120 moves to the area where the inner diameter of the pipe becomes smaller, the two driven wheels 221 on the same mounting plate 210 move closer to each other due to the squeezing of the inner wall of the pipe, which can reduce the extension diameter between the two driven wheels 221, so that it can smoothly pass through the area where the inner diameter of the pipe becomes smaller, reducing the possibility of getting stuck in the pipe. When the driven wheel 221 moves, it drives the first driving member 222 to move synchronously, causing the elastic member 223 to elastically deform and compress. The reverse elastic force generated by the compression of the elastic member 223 is used to drive the driven wheel 221 to fit closely to the inner wall of the pipe, which can reduce the deviation of the movement trajectory of the measuring component 120, thereby improving the movement stability of the measuring component 120 and further improving the accuracy of measurement and positioning.

[0030] It should be noted that the measuring component 120 may include a gyroscope and an accelerometer. The gyroscope is used for the movement orientation of the installation bin 110, and the accelerometer is used for measuring the movement acceleration of the installation bin 110. The position data of the installation bin 110 can be calculated by the coordinated use of the gyroscope and the accelerometer. By passing through the inside of the pipeline, the position coordinates of the positioning pipeline can be continuously measured, and the position map of the pipeline line can be obtained according to the movement trajectory of the measuring component 120 in the pipeline.

[0031] When the measuring component 120 passes through the area where the inner diameter of the pipe becomes smaller, the elastic member 223 recovers elastically, and the elastic member 223 can drive the first driving member 222 and the driven wheel 221 to move toward the inner wall of the pipe, so that the driven wheel 221 is close to the inner wall of the pipe, so as to improve the movement stability of the measuring component 120 and thereby improve the accuracy of measurement positioning.

[0032] The first driving member 222 may be an electric push rod or a linear slide module, and a power supply 300 is installed in the installation chamber 110. The power supply 300 is used to supply power to the first driving member 222, which can reduce the overall volume of the adjustable pipeline measurement and positioning device, thereby facilitating carrying and transportation. The power supply 300 and the measuring component 120 are both arranged in the installation chamber 110. The installation chamber 110 is used to protect the power supply 300 and the measuring component 120, which can reduce the risk of damage to the power supply 300 and the measuring component 120 and extend their service life.

[0033] The elastic member 223 may be a spring or a spring sheet, etc., which can generate elastic deformation and drive the first driving member 222 and the driven wheel 221 to move toward the inner wall of the pipe through elastic force.

[0034] A cover plate 115 is connected to the top of the installation bin 110, and the cover plate 115 is connected to the installation bin 110 by bolts. The cover plate 115 is provided with heat dissipation holes, and the cover plate 115 can be disassembled and assembled by tightening the bolts, so that the maintenance of the components in the installation bin 110 is convenient, and the heat in the installation bin 110 can be dissipated in time through the heat dissipation holes, which can improve the operating stability of the components in the installation bin 110.

[0035] It is understandable that, referring to Figure 4The first driving member 222 is provided with a guide rod 224 at the fixed end, the mounting plate 210 is provided with a guide block 225, the guide block 225 is provided with a guide hole 226, the guide rod 224 is inserted into the guide hole 226, and the elastic member 223 is a spring, which is sleeved on the guide rod 224. Since the first driving member 222 is provided with a guide rod 224 at the fixed end, the guide block 225 is provided with a guide hole 226, and the guide rod 224 is inserted into the guide hole 226, when two first driving members 222 on the same mounting plate 210 move toward or away from each other, the guide rod 224 slides in the guide hole 226, and the guide hole 226 is used to guide the movement of the guide rod 224, so as to drive the first driving member 222 and the driven wheel 221 to move, which can reduce the shaking and deviation of the first driving member 222 and the driven wheel 221, thereby improving the movement stability of the first driving member 222 and the driven wheel 221. In addition, since the spring is sleeved on the guide rod 224, the guide rod 224 guides the spring to be compressed and restored in the axial direction of the guide rod 224, which can reduce the possibility of bending when the spring is compressed and deformed, thereby improving the movement stability of the first driving member 222 and the driven wheel 221.

[0036] Specifically, refer to Figure 4 A stopper 227 is provided at one end of the guide rod 224 away from the first driving member 222, and the stopper 227 can abut against the guide block 225 to limit the moving range of the guide rod 224. By abutting against the guide block 225 by the stopper 227 to limit the moving range of the guide rod 224, the guide rod 224 can be prevented from slipping out of the guide hole 226, and the movement of the driven wheel 221 toward the inner wall of the pipe can be limited, thereby reducing the risk of damaging the inner wall of the pipe due to the elastic force of the elastic member 223 driving the driven wheel 221 to quickly approach and abut against the inner wall of the pipe.

[0037] Specifically, refer to Figure 4The telescopic assembly 220 also includes a fixed seat 228, two sliders 229 and two connecting rods 230. The mounting plate 210 is provided with two first limiting holes 211. The two sliders 229 of the same group of telescopic assemblies 220 are both slidably connected to one of the first limiting holes 211. The fixed seat 228 is fixedly connected to one end of the guide rod 224 close to the first driving member 222. One ends of the two connecting rods 230 are respectively rotatably connected to the two sliders 229, and the other ends of the connecting rods 230 are rotatably connected to the fixed seat 228. When the driven wheel 221 moves in a direction away from the inner wall of the pipe due to being squeezed, the guide rod 224 drives the fixed seat 228 to move, causing the two connecting rods 230 to rotate in a direction away from each other, thereby driving the two sliders 229 to slide away from each other in the first limiting hole 211. When the slider 229 abuts against the wall of the first limiting hole 211, it can limit the first driving member 222 from moving in a direction close to the guide block 225, thereby reducing the risk of collision and damage between the first driving member 222 and the guide block 225. In conjunction with the limiting function of the stop block 227, it can limit the travel of the telescopic movement of the driven wheel 221, thereby improving the reliability of the telescopic movement of the driven wheel 221.

[0038] It should be noted that one end of the spring can be connected to the guide block 225, and the other end of the spring can be connected to the fixed seat 228, so that the spring can directly drive the fixed seat 228 to move in the direction close to the inner wall of the pipe, thereby causing the two connecting rods 230 to rotate in the direction close to each other, thereby driving the two sliders 229 to slide close to each other in the first limiting hole 211. By using the first limiting hole 211 to guide and limit the slider 229, the stability of the extension movement of the driven wheel 221 can be improved.

[0039] It is understandable that, referring to Figures 1 to 3 The front and rear sides of the installation chamber 110 are respectively connected with support boxes 111, and the support boxes 111 are arranged along the moving direction of the installation chamber 110. The installation plate 210 is connected with support rods 213, and the two support rods 213 are respectively slidably connected to one support box 111, so that the distance between the two installation plates 210 can be adjusted. Since the two support rods 213 are respectively slidably connected to one support box 111, the distance between the installation plate 210 and the installation chamber 110 can be adjusted as needed by moving the support rods 213, thereby adjusting the distance between the driven wheel 221 and the installation chamber 110, and by moving the two installation plates 210 closer to or away from each other, the distance between the two installation plates 210 can be adjusted, thereby adjusting the overall length of the adjustable pipeline measurement and positioning device, which is suitable for measuring and positioning pipelines with different arc angles, so as to improve the versatility of the adjustable pipeline measurement and positioning device.

[0040] It should be noted that after the mounting plate 210 is adjusted to a preset position, the position can be fixed by means of latches, bolts, etc.

[0041] Specifically, refer to Figure 3 The side wall of the support box 111 is provided with a plurality of first positioning holes 112, and the plurality of first positioning holes 112 are evenly arranged along the moving direction of the installation chamber 110. The support rod 213 is provided with a second positioning hole 214, and the first positioning hole 112 is penetrated by a fastener 113, and the fastener 113 is threadedly connected to the second positioning hole 214, and the fastener 113 can abut against the side wall of the support box 111 to locate the position of the support rod 213. When the mounting plate 210 is adjusted to the preset position, the fastener 113 is tightened to make the fastener 113 abut against the side wall of the support box 111, so that the position of the fixed mounting plate 210 can be conveniently adjusted, and since the plurality of first positioning holes 112 are evenly arranged along the length direction of the support box 111, the mounting plate 210 can be positioned at different positions along the length direction of the support box 111 by aligning the second positioning hole 214 with the first positioning holes 112 at different positions, and tightening the fastener 113, so as to improve the convenience of adjustment.

[0042] It should be noted that the fastener 113 may be a bolt or a screw, etc., which is not limited here.

[0043] Specifically, refer to Figure 3 The support box 111 is provided with a second limiting hole 114, and the support rod 213 is provided with a limiting block 215, and the limiting block 215 is slidably connected to the second limiting hole 114. The second limiting hole 114 guides and limits the limiting block 215, so that the stability of the movement of the support rod 213 can be improved, and the limiting block 215 can be on the wall surface of the second limiting hole 114 to limit the movement of the support rod 213, reducing the possibility of the support rod 213 slipping off the support box 111, so as to improve the reliability of adjustment.

[0044] Specifically, refer to Figure 1 and Figure 2 A support block 216 is provided on the side of the mounting plate 210 away from the support rod 213, and the support block 216 is provided with a through hole 217. Since the support block 216 is provided with a through hole 217, the traction rope can pass through the through hole 217 and be fastened to the support block 216, and the adjustable pipeline measurement and positioning device can be retracted by pulling the traction rope, so that the adjustable pipeline measurement and positioning device stuck in the pipeline can be conveniently taken out. Since the driving wheel 131 is rotatably connected to the bottom of the installation chamber 110, the driving wheel 131 is driven to rotate by the second driving member 132 to drive the installation chamber 110 to move, so that the installation chamber 110 can be automatically moved through the pipeline.

[0045] It should be noted that the second driving member 132 may be a servo motor or a stepping motor, etc., which can drive the driving wheel 131 to rotate. The first driving member 222 and the second driving member 132 are both powered by the power supply 300 .

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
