Description

Technical Field

[0002] Surveying and mapping, also known as metrology, is the science and technology that studies the shape and size of the Earth, as well as the shape, location, and elevation of various natural phenomena and man-made structures on its surface. Surveying and mapping has extensive applications in national economic development, national defense, and scientific research. Pipelines are pipes that connect pumps, valves, or control systems, used to transport liquids, gases, or powdered fluids ground from solids. When exploring pipelines, probing tools are inserted into the pipelines for inspection.

[0003] A Chinese patent with authorization announcement number CN219640979U discloses a pipeline measurement and detection tool. The cleaning mechanism is set up to clean the extension line after the water supply and drainage pipeline is measured and detected by the extension line and the detection head. This prevents contamination of the extension line and the detection head surface that affects subsequent use. Research on the above-mentioned product has found that there are still some shortcomings: when the line is reeled in, the extension line cannot be arranged regularly and evenly on the winding roller, resulting in the extension line being partially entangled on the winding roller; and when the line is reeled in, the extension line only partially contacts the cleaning pad, resulting in severe local wear of the cleaning pad, low utilization efficiency and short life. In addition, the distance between the two cleaning plates is fixed, making the cleaning pad replacement operation difficult. Therefore, the existing technology urgently needs to be further improved.

[0042] Example 1: Combination Figure 1-5 Understand, a measuring and probing device for conveying pipelines, a retracting mechanism 2 and a cleaning mechanism 4 are fixedly mounted on a bottom plate 1, the cleaning mechanism 4 is located in front of the retracting end of the retracting mechanism 2, the cleaning mechanism 4 and the retracting mechanism 2 are arranged front and back, a guide mechanism 3 is provided between the retracting mechanism 2 and the cleaning mechanism 4, and the guide mechanism 3 is connected to the retracting mechanism 2 through a belt transmission assembly,

[0043] In the retracting and unwinding mechanism 2, the winding roller 204 is rotated by the drive shaft 203 and is arranged inside the U-shaped pay-off frame 201. The servo motor 202 is installed outside the pay-off frame 201. The output end of the servo motor 202 is connected to the drive shaft 203. The connecting wire 205 is wound around the winding roller 204. One end of the connecting wire 205 is wound around the surface of the winding roller 204, and the other end passes through the guide mechanism 3 and the cleaning mechanism 4 and is fixedly connected to the probe head 206.

[0044] In the guide mechanism 3, the left and right ends of the reciprocating screw 302 are rotatably mounted with the guide frame, and a wire ring 304 is fixed on the slider 303 that is slidably mounted with the reciprocating screw 302. One end of the reciprocating screw 302 is connected to the drive shaft 203 through a belt transmission assembly. The guide frame includes two vertical plates 301 arranged relatively spaced apart on the left and right. The two vertical plates 301 are fixedly connected by a guide rod 305, which passes through the slider 303.

[0045] In the cleaning mechanism 4, the first cleaning plate 403 is horizontally arranged between the two mounting plates 401, and the second cleaning plate 409 is arranged above the first cleaning plate 403 through a lifting drive assembly and is arranged relatively parallel to the first cleaning plate 403.

[0046] Working process: In the retractable / retractable mechanism 2, the servo motor 202 drives the winding roller 204 to rotate, thereby retracting and releasing the connecting wire 205. The guide mechanism 3 is connected to the retractable / retractable mechanism 2 via a belt drive assembly. In the guide mechanism 3, the reciprocating screw 302 causes the slider 303 and the wire loop 304 located on the slider 303 to reciprocate along the reciprocating screw 302. Driven by the wire loop 304 reciprocating along the reciprocating screw 302, the connecting wire 205 inserted therein also reciprocates. This ensures that during retraction, the connecting wire 205 is evenly and regularly wound along the winding roller 204, eliminating any localized entanglement. This ensures that the winding is neat and the payout is orderly, allowing the probe's penetration length and position within the pipeline to be accurately determined during the payout process. Combined with the elongated cleaning mechanism 4, during retraction, the connecting wire 205 reciprocates on the cleaning pad 414, avoiding localized friction with the cleaning pad 414 and improving the efficiency and service life of the cleaning pad 414.

[0047] Example 2: Based on the structure of Example 1, combined Figure 5 It is understood that the lifting drive assembly is arranged on the inner side of the opening on the mounting plate 401, and the lifting drive assembly includes: a hydraulic cylinder 406 and a lifting block 407. The lifting block 407 is installed in a vertical sliding manner with the mounting plate 401. The cylinder body of the hydraulic cylinder 406 is fixed on the mounting plate 401, and the end of the piston rod is fixedly connected to the lifting block 407; the end of the second cleaning plate 409 is rotatably connected to the lifting block 407 through the second rotating shaft 408; the hydraulic cylinder 406 drives the lifting block 407 to perform a lifting movement relative to the mounting plate 401. When it is lifted, the distance between the first cleaning plate 403 and the second cleaning plate 409 is increased to clean the cleaning plate 409. The replacement of the cleaning pad 414 provides greater operating space. The first cleaning plate 403 is rotatably mounted on the mounting plate 401 via a first rotating shaft 402. The end of the first rotating shaft 402 is fixedly connected to the first rocker arm 404. The first rocker arm 404 is equipped with a first positioning pin 405. The mounting plate 401 has a first positioning hole 412 adapted to the first positioning pin 405. The end of the second rotating shaft 408 is fixedly connected to the second rocker arm 410. The second rocker arm 410 is equipped with a second positioning pin 411. The mounting plate 401 has a second positioning hole 413 adapted to the second positioning pin 411. The first rocker arm 404 can rotate the upward-facing cleaning pad 414 90 degrees to facilitate replacement. The first positioning pin 405 is used to lock the cleaning pad 414 into the corresponding first positioning hole 412 for positioning, ensuring the replacement process, stable equipment structure, and safe operation. The upper and lower positioning components have similar structures and functions.

[0048] During normal operation, the first cleaning plate 403 and the second cleaning plate 409 are arranged relatively parallel to the cleaning pad 414, and the distance between the upper and lower cleaning pads 414 is approximately equal to the outer diameter of the connecting line 205. The first positioning pin 405 is placed in the first positioning hole 412 on the side, and the second positioning pin 411 is placed in the second positioning hole 413 below to achieve fixation; the connecting line 205 is retracted and released through the upper and lower cleaning pads 414 for cleaning under the action of the retracting mechanism 2, and at the same time, under the action of the guiding mechanism 3, it will reciprocate horizontally between the upper and lower cleaning pads 414, avoiding only local friction with the cleaning pad 414, thereby improving the utilization efficiency and service life of the cleaning pad 414. When the cleaning pad 414 needs to be replaced, the second positioning pin 411 is first disengaged from the second positioning hole 413 below, and then the hydraulic cylinder 406 drives the lifting block 407 to lift the second cleaning plate 409 away from the first cleaning plate 403 relative to the mounting plate 401. After the lifting is completed, the second rocker arm 410 is rotated to make the second cleaning plate 409 turn 90 degrees, and the second positioning pin 411 is placed in the second positioning hole 413 on the side. Similarly, the first rocker arm 404 is rotated to make the first cleaning plate 403 turn 90 degrees, and the first positioning pin 405 is placed in the first positioning hole 412 below, so that the cleaning pad 414 is vertically exposed on the same side, which is convenient for the replacement operation. After the replacement is completed, the first cleaning plate 403 is first restored to the working position and fixed, and then the second cleaning plate 409 is rotated and lowered to reach the working position.

[0049] Example 3: Based on the structure of Example 2, combined Figure 1 、 3 As understood from 4, the belt transmission assembly includes: a driving pulley 601, a driven pulley 602 and a synchronous belt 603. The driving pulley 601 is installed at the end of the drive shaft 203 in the retracting mechanism 2, and the driven pulley 602 is installed at the end of the reciprocating screw 302 in the guide mechanism 3. The driving pulley 601 and the driven pulley 602 are connected for transmission through the synchronous belt 603. The guide mechanism 3 and the retracting mechanism 2 are connected through the belt transmission assembly, which can realize synchronous transmission and facilitate the realization of the same frequency.

[0050] The base plate 1 is a square rigid flat plate, and universal wheels 101 with brake functions are respectively provided at the four corners of the bottom of the base plate 1.

[0051] The inner wall of the wire loop 304 is a glazed ceramic layer with an arc-shaped curved surface structure. The connecting wire 205 passes through the wire loop 304. The smooth ceramic layer basically does not damage the connecting wire 205, and also reduces the friction between the connecting wire 205 and the wire loop 304, making it more durable.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
