Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection, and specifically relates to a pipeline endoscope four-wheel linkage cable length data acquisition device. Background Technology

[0002] A pipe endoscope is a device used to inspect the internal condition of pipes. It typically consists of a crawler, cable, camera, and other accessories. The crawler carries the camera deep into the pipe to capture real-time images or videos of the pipe interior, helping to detect problems such as blockages, corrosion, cracks, or other structural damage.

[0003] When using a pipe endoscope, the distance the camera has entered the pipe needs to be determined by collecting the length of the cable exiting the pipe. Existing pipe detection cable length data acquisition devices are usually simple in structure, with only a single main wheel assembly mounted on the encoder. These devices are prone to slippage and cable damage, and the collected data is inaccurate, which can lead to misjudgments and safety hazards. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a four-wheel linkage cable length data acquisition device for pipeline endoscopes, thereby improving the accuracy and effectiveness of data acquisition.

[0005] Another objective of this invention is to provide a four-wheel linkage cable length data acquisition device for a pipeline endoscope, which has low friction to avoid damaging the cable and can prevent idling and slippage.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a four-wheel linkage cable length data acquisition device for a pipeline endoscope, comprising:

[0008] case;

[0012] The guide wheel assembly is provided in three sets. The encoder wheel assembly and the three sets of the guide wheel assembly are all mounted on the housing and connected by synchronous belt drive.

[0013] The encoder wheel assembly and the three sets of conductor wheel assemblies enclose a quadrilateral structure, and a gap is formed between the four for threading cables.

[0015] Furthermore, the encoder wheel assembly includes an encoder wheel, an encoder, and an encoder wheel rubber ring. The encoder is fixed to the housing, and the data acquisition shaft of the encoder is fixedly connected to the encoder wheel. The encoder wheel rubber ring is sleeved on the encoder wheel, and a first belt mounting groove is provided on the outer side of the encoder wheel. The synchronous belt is in contact with the inner wall of the first belt mounting groove.

[0016] Furthermore, the guide wheel assembly includes a guide wheel, a guide wheel shaft, a guide wheel rubber ring, and a guide bearing. The guide wheel shaft is fixed to the housing, the guide wheel is rotatably sleeved on the guide wheel shaft, the guide bearing is disposed between the guide wheel and the guide wheel shaft, and the guide wheel rubber ring is sleeved on the outside of the guide wheel.

The transmission connection between the encoder wheel and the three guide wheels is a cross transmission.

[0018] Furthermore, the housing includes a cover plate, an outer shell, and a bottom plate. The cover plate and the bottom plate are respectively installed at the upper and lower ends of the outer shell.

[0020] Furthermore, a hollow guide rod is provided on the inner wall of the outer casing, and the upper part of the guide wheel shaft passes through the guide rod and is locked to the wall of the outer casing by screws.

[0021] The beneficial effects of this utility model are as follows: Compared with the prior art, this application sets up one encoding wheel and three encoding wheels to form a four-wheel linkage structure.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To achieve the above objectives, the technical solution of this utility model is as follows:

[0032] See Figure 1-7 As shown, this embodiment provides a four-wheel linkage cable length data acquisition device for a pipeline endoscope, including:

[0033] Casing 1;

[0034] A guide wheel assembly 2 that can rotate with cable 100;

[0035] Encoding wheel assembly 3 capable of measuring the 100mm outgoing length of a cable;

[0036] A synchronous belt 4 capable of transmitting the rotation of the guide wheel assembly 2 and the encoder wheel assembly 3;

[0037] The guide wheel assembly 2 is provided with three sets. The encoder wheel assembly 3 and the three sets of guide wheel assemblies 2 are all mounted on the housing 1 and are connected by synchronous belt 4.

[0038] The encoder wheel assembly 3 and the three sets of conductor wheel assemblies 2 form a quadrilateral structure, and a gap 5 is formed between the four for threading the cable 100.

[0039] In this embodiment, during pipeline detection, the cable 100 passes through the gap 5 and exits. The surface of the cable 100 is in contact with the encoder wheel assembly 3 and the three sets of guide wheel assemblies 2. When the cable 100 moves forward, it drives the encoder wheel assembly 3 and the guide wheel assembly 2 to rotate synchronously. Since the encoder wheel assembly 3 and the three sets of guide wheel assemblies 2 are connected by a synchronous belt 4, as long as one of the guide wheel assemblies 2 rotates normally, it can drive the other two guide wheel assemblies 2 and the encoder wheel assembly 3 to rotate, thereby driving the encoder to rotate for counting. This avoids the problem of the encoder wheel spinning freely and slipping, making the collected data more accurate and avoiding data collection errors that may leave safety hazards. At the same time, the combination of the encoder wheel assembly 3 and the three sets of guide wheel assemblies 2 forms a four-wheel linkage structure, which also makes the clamping and fixing of the cable 100 more stable and the forward movement of the cable 100 smoother, avoiding situations such as wire tangling, thereby avoiding damage to the cable 100.

[0040] Furthermore, the encoder wheel assembly 3 and the three sets of conductor wheel assemblies 2 are positioned opposite each other to form two clamping and fixing positions 6, with the gap 5 passing through the two clamping and fixing positions 6 in sequence. By clamping and fixing the cable 100 through the two clamping and fixing positions 6, the linkage between the cable 100 and the conductor wheel assembly 2 and the encoder wheel assembly 3 can be made more stable, thereby avoiding the problems of slippage and free rotation of the encoder wheel assembly 3.

[0041] Furthermore, the encoder wheel assembly 3 includes an encoder wheel 31, an encoder 32, and an encoder wheel rubber ring 33. The encoder 32 is fixed to the housing 1 with screws, and the data acquisition shaft of the encoder 32 is locked to the encoder wheel 31 with screws. The encoder wheel rubber ring 33 is fitted onto the encoder wheel 31. A first belt mounting groove 34 is provided on the outer surface of the encoder wheel 31, and the synchronous belt 4 is in contact with the inner wall of the first belt mounting groove 34. When the cable 100 is inserted into the gap 5, the cable 100 can be tightly attached to the surface of the encoder wheel rubber ring 33. When the cable 100 moves forward, it can drive the encoder wheel 31 to rotate, thereby driving the data acquisition shaft of the encoder 32 to rotate, counting the number of rotations of the encoder wheel 31, and thus collecting the length of the cable 100.

[0042] Furthermore, the guide wheel assembly 2 includes a guide wheel 21, a guide wheel shaft 22, a guide wheel rubber ring 23, and a guide bearing 24. Both ends of the guide wheel shaft 22 are fixed to the housing 1. The guide wheel 21 is rotatably mounted on the guide wheel shaft 22. The guide bearing 24 is positioned between the guide wheel 21 and the guide wheel shaft 22. The guide wheel rubber ring 23 is fitted over the guide wheel 21. When the cable 100 passes through the gap 5, the cable 100 can be tightly attached to the surface of the guide wheel rubber ring 23. As the cable 100 moves forward, it drives the guide wheel 21 to rotate, which in turn drives the encoder wheel 31 to rotate via the synchronous belt 4, thus enabling the collection of cable 100 length data. In this embodiment, three guide wheels are provided, which can be combined with the encoder wheel 31 to form a four-wheel linkage. Only one wheel needs to operate normally to achieve accurate counting, improving the accuracy of the collected data.

[0043] Furthermore, two vertically opposite second belt mounting grooves 25 are provided on the outer side of the guide pulley 21. The synchronous belt 4 is staggered vertically within the second belt mounting grooves 25 of the three guide pulleys 21 and fits against the inner wall of the second belt mounting groove 25. The transmission connection between the encoder wheel 31 and the three guide pulleys 21 is a cross transmission. In this application, since the three guide pulleys 21 are horizontally arranged and their second belt mounting grooves 25 are at the same height, and each guide pulley 21 is provided with two second belt mounting grooves 25, the synchronous belt 4 can be staggered vertically on adjacent guide pulleys 21 for cross transmission, making the transmission structure more stable. At the same time, the staggered arrangement of the synchronous belt 4 allows the intersecting parts of the synchronous belt 4 to be misaligned vertically, avoiding friction between them and affecting the transmission effect.

[0044] Furthermore, the housing 1 includes a cover plate 11, an outer shell 12, and a bottom plate 13. The cover plate 11 and the bottom plate 13 are respectively fixedly installed at the upper and lower ends of the outer shell 12 with screws. The outer shell 12 has a cavity, and the encoder wheel 31, the guide wheel 21, and the guide wheel shaft 22 are installed in the cavity. The encoder 32 is fixedly connected to the cover plate 11 with screws, and the guide wheel shaft 22 is fixedly connected to the cover plate 11 and the bottom plate 13 with screws. The data acquisition shaft of the encoder 32 passes through the cover plate 11 and is connected to the encoder wheel 31.

[0045] Furthermore, a cable channel 7 corresponding to the gap 5 is provided inside the outer casing 12. The gap 5 is located within the cable channel 7. Support grooves 8 are located at both ends of the cable channel 7. Rollers 9 for limiting the cable 100 are installed within the support grooves 8, and the rollers 9 are rotatably connected to the inner wall of the support grooves 8. In this embodiment, as the cable 100 advances, it passes through the cable channel 7 within the outer casing 12. The rollers 9 at both ends of the cable channel 7 rotate with the cable 100 and can press the cable 100, limiting its movement and preventing it from detaching from the outer casing 12, thereby improving the structural stability of the data acquisition device.

[0046] Furthermore, a hollow guide rod 14 is provided on the inner wall of the outer casing 12, and the upper part of the guide wheel shaft 22 passes through the guide rod 14 and is locked to the wall of the outer casing 12 by screws.

[0047] The beneficial effects of this embodiment are as follows: Compared with the prior art, this application sets up one encoding wheel and three encoding wheels to form a four-wheel linkage structure. Only one wheel needs to rotate normally to ensure the normal operation of the encoder, thereby avoiding the problems of the encoding wheels spinning freely and slipping. The collected data is more accurate and avoids data collection errors that may leave safety hazards. At the same time, the four-wheel linkage structure makes the cable clamping and fixing more stable and the cable advance more orderly, avoiding situations such as wire tangling, thereby avoiding damage to the cable. Finally, the acquisition device of this application can realize a modular design, which can facilitate production and maintenance.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
