Description

Technical Field

[0001] This utility model relates to the field of tracked vehicle technology, and in particular to a track monitoring device for tracked vehicles. Background Technology

[0002] For example, a patent titled "Tracked Vehicle" (patent application number: CN201920816559.X) discloses a tracked vehicle with an added protective mechanism on the outside, which can effectively prevent the tracks from contacting other obstacles such as walls, ensuring smooth movement. In the event of side contact, the contact of guide wheels or guide rollers achieves rolling guidance, effectively avoiding direct contact between the tracks. Through rolling guidance, differential speed between the two sides is avoided, ensuring continued forward movement. It can be widely used in application scenarios requiring automatic obstacle avoidance and automatic patrol. However, it lacks a device for monitoring track faults. When a track fault occurs, it usually breaks directly, causing the track pins to bend and break. Monitoring can usually only be done manually when the vehicle is stationary. It cannot be monitored during use, and its efficiency needs to be improved.

[0003] Therefore, it is necessary to propose a track monitoring device for tracked vehicles to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a track monitoring device for tracked vehicles to solve the problem of the lack of a device for monitoring track faults. When a track malfunctions, it usually breaks directly, which can cause the track pins to bend and break. Usually, it can only be monitored manually when the vehicle is stationary. It cannot be monitored during use, and the efficiency of use needs to be improved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a track monitoring device for tracked vehicles, comprising a frame, a track body disposed on the side of the frame, a square tube disposed within the inner ring of the track body, a second sliding plate slidably disposed inside the square tube, a pressure sensor fixedly connected to the lower surface of the second sliding plate, and the pressure sensor abutting against the bottom inner wall of the square tube, a U-shaped frame above the square tube, a rotating shaft rotatably disposed on the top of the U-shaped frame, a rotating roller fixedly connected to the rotating shaft, and the rotating roller adhering to the lower surface of the top of the track body, and a connecting component cooperating with the U-shaped frame being disposed between the U-shaped frame and the square tube.

[0006] Preferably, the connecting assembly includes a square groove, a sliding column, a first sliding plate, and a second spring. The square groove is opened through the top of the square tube. The sliding column is slidably disposed inside the square groove. The first sliding plate is slidably connected to the inside of the square tube. The sliding column is fixedly connected to the first sliding plate. The second sliding plate is located below the first sliding plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-5 The track monitoring device for the tracked vehicle shown includes a frame 1, and a track body 2 is provided on the side of the frame 1. In actual use, it is equipped with a drive wheel, a driven wheel, a load-bearing wheel, and an elastic tensioning structure to cooperate with the track body 2.

[0021] A square tube 4 is disposed within the inner ring of the track body 2. A fixing plate 3 is fixedly connected to the bottom of the square tube 4 and is fixedly connected to the frame 1. A second sliding plate 14 is slidably disposed inside the square tube 4. A pressure sensor 12 is fixedly connected to the lower surface of the second sliding plate 14 and abuts against the bottom inner wall of the square tube 4. A U-shaped frame 6 is disposed above the square tube 4. A rotating shaft 7 is rotatably disposed on the top of the U-shaped frame 6. A rotating roller 8 is fixedly connected to the rotating shaft 7 and fits against the lower surface of the top of the track body 2.

[0022] A connecting component that mates with the U-shaped frame 6 is provided between the U-shaped frame 6 and the square tube 4. The connecting component includes a square groove, a sliding post 5, a first sliding plate 13, and a second spring 15. The square groove is opened through the top of the square tube 4. The sliding post 5 is slidably disposed inside the square groove. The first sliding plate 13 is slidably connected to the inside of the square tube 4. The sliding post 5 is fixedly connected to the first sliding plate 13. The second sliding plate 14 is located below the first sliding plate 13. One end of the second spring 15 is fixedly connected to the first sliding plate 13, and the other end of the second spring 15 is fixedly connected to the second sliding plate 14.

[0023] Specifically, the roller 8 is in contact with the inner ring surface of the track body 2. The first slide plate 13 is driven to slide downward inside the square tube 4 through the U-shaped frame 6 and the sliding column 5, and squeezes the second spring 15 to contract. The second spring 15 squeezes the pressure sensor 12 through the second slide plate 14, and the pressure sensor 12 monitors the pressure of the track body 2.

[0024] When the track body 2 is disconnected, the track body 2 loses contact with the roller 8, and the reset force of the second spring 15 causes the slide 5 to reset, while releasing the pressure sensor 12, thereby enabling real-time monitoring of the fault of the track body 2.

[0025] By setting up structures such as the rotating roller 8, pressure sensor 12, and connecting components, when the track body 2 is disconnected, the track body 2 disengages from the rotating roller 8, and the reset force of the second spring 15 causes the sliding column 5 to reset, while releasing the pressure sensor 12. This enables real-time monitoring of faults in the track body 2 and improves the utilization efficiency of the tracked vehicle.

[0026] In practical use, the monitoring device can also be used in conjunction with the elastic tensioning structure. The monitoring device monitors the tension of the track body 2. When loosening occurs, the pressure detected by the monitoring device is lower than the set threshold. The controller then controls the elastic tensioning structure to tension the track body 2, which can be adjusted according to specific usage conditions. The elastic tensioning structure includes structures such as tensioning wheels. The elastic tensioning structure and its working principle are common existing technologies and will not be described in detail here.

[0027] Considering that impurities are easily attached to the roller 8, in order to clean the impurities and reduce the wear between the roller 8 and the track body 2, a cleaning assembly for cleaning the roller 8 is provided on the U-shaped frame 6. The cleaning assembly includes a scraper 9, a round rod 10 and a first spring 11. The round rod 10 is rotatably connected to the U-shaped frame 6 and is located below the roller 8. One end of the scraper 9 is fixedly connected to the round rod 10, and the other end of the scraper 9 is attached to the outer wall of the roller 8. One end of the first spring 11 is fixedly connected to the scraper 9, and the other end of the first spring 11 is fixedly connected to the U-shaped frame 6.

[0028] The cleaning component is set up so that the elastic support force of the first spring 11 keeps the scraper 9 always in contact with the roller 8. When the roller 8 rotates, the scraper 9 pushes and scrapes the impurities on the outside of the roller 8 to clean them, reducing the wear between the roller 8 and the track body 2.
