Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, and in particular to an automatic inspection robot for a track-type belt conveyor. Background Technology

[0002] Belt conveyors are key equipment for the continuous transport of bulk materials in mines, ports, thermal power plants, and other fields. Due to their long conveying distances and harsh operating environments (such as high dust and vibration), real-time monitoring and regular inspection of belt conveyor operation are crucial.

[0003] To replace the high-risk, low-efficiency manual inspection, track-mounted automated inspection robots have been adopted. These robots typically run along pre-set guide rails beside the conveyor belt and are equipped with sensors such as cameras to monitor the condition of key components of the conveyor belt.

[0004] However, existing track-based inspection robots have design shortcomings. Specifically, belt conveyors are large and three-dimensional systems, and the key components that need to be inspected, such as the load-bearing idlers, belt surface, return idlers, frame, and drive unit, are distributed at different vertical heights.

[0005] Currently, most inspection robots are equipped with cameras mounted at a fixed height or on a bracket. This fixed installation method severely limits the camera's field of view, making it impossible to flexibly adjust to different heights of the target being inspected. When close-up observation of components at high or low locations is required, fixed cameras struggle to acquire clear and accurate images, easily creating blind spots and resulting in low inspection accuracy. This prevents comprehensive, multi-angle inspection and reduces the overall efficiency of automated inspection.

[0006] Therefore, this utility model proposes an automatic inspection robot for track-type belt conveyors to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems in the existing automatic inspection robot for track-mounted belt conveyors, such as the fixed installation height of the camera, which leads to a limited field of view and an inability to flexibly adjust the observation angle, resulting in blind spots and low inspection accuracy, this utility model aims to provide an automatic inspection robot for track-mounted belt conveyors with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an automatic inspection robot for a track-type belt conveyor, including: a guide rail and a mover that slides and engages with the guide rail; The mobile device is fixedly connected to a lifting mechanism and a track cleaning mechanism.

[0009] The lifting mechanism includes a vertically arranged fixed column, a lifting column slidably connected to the fixed column, an observer and an all-around camera fixedly connected to the top of the lifting column, and a drive component for driving the lifting column to rise and fall.

[0010] Furthermore, the drive assembly includes a motor, a rotating rod, a rotating wheel, a belt, and a lifting block, all housed within a protective box. The drive end of the motor is connected to the rotating rod, the rotating wheel is fixed to the rotating rod, the belt surrounds the rotating wheel, and the lifting block is fixedly connected to the belt and to the lifting column.

[0011] The track cleaning mechanism includes a brush head for cleaning the guide rail and a motor for driving the brush head to rotate.

[0012] Preferably, the lifting mechanism further includes a fixing plate, and the bottom end of the fixing column is fixedly connected to the upper surface of the mover through the fixing plate.

[0013] Preferably, the lifting mechanism further includes a telescopic plate, which is telescopically fitted onto the outside of the fixed column and the lifting column to protect the sliding mating part of the lifting column.

[0014] Preferably, the drive assembly further includes a limiting rod and a limiting wheel, the limiting wheel being rotatably connected to one end of the limiting rod, and the belt being arranged around the limiting wheel for tensioning the belt.

[0015] Preferably, the protective box is fixedly connected to the mobile device, and the motor (361) is housed inside the protective box.

[0016] Preferably, the track cleaning mechanism further includes a transmission rod, the drive end of the second motor is fixedly connected to one end of the transmission rod, and the brush head is fixedly connected to the other end of the transmission rod.

[0017] Preferably, the outer circumferential surface of the brush head is uniformly covered with bristles; the track cleaning mechanism also includes a second protective box, which is fixed to the mover, and the second motor is housed inside the second protective box.

[0018] Preferably, the mover further includes at least two guide wheels, which are rotatably mounted on the side wall of the mover and roll in contact with the side of the guide rail to constrain the lateral displacement of the mover.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting up a lifting mechanism, uses a motor to drive a belt transmission assembly to make the lifting column move the omnidirectional camera up and down, and uses a fixed column, a fixed plate, a telescopic plate and a protective box to protect the internal structure, solves the problems of fixed camera height, limited detection range, low accuracy and easy collision damage in complex environments in the existing technology of inspection robot cameras. It achieves the technical effect of allowing the camera to be flexibly adjusted at different heights, expanding the detection range, improving detection accuracy, and effectively protecting the camera.

[0020] 2. This utility model, by setting up a track cleaning mechanism, uses a motor two inside the protective box two to drive the brush head to rotate and run synchronously when the inspection robot moves, which solves the problem in the prior art that impurities easily accumulate on the guide rail, resulting in unstable robot operation, poor reliability, and easy wear of parts. It achieves the technical effects of automatically cleaning the track, improving the stability and reliability of the inspection robot operation, protecting robot parts, extending the service life of the track, and improving the overall inspection efficiency.

[0023] Example: Reference Figures 1 to 5 This utility model provides an automatic inspection robot for track-type belt conveyors, which aims to solve the problems in the prior art where the fixed height of the inspection robot's camera leads to a limited detection range, and the track impurities affect the stability of operation.

[0024] like Figure 1 As shown, the track-type automatic inspection robot for belt conveyors includes a guide rail 1 and a moving device 2 that slides on the guide rail 1. The moving device 2 serves as the mounting base for the entire device and moves on the guide rail 1. A lifting mechanism 3 and a track cleaning mechanism 7 are fixedly connected to the moving device 2. The lifting mechanism 3 includes a vertically arranged fixed column 31, a lifting column 32 that slides on the fixed column 31, an observation device 4 and an all-around camera 5 fixedly connected to the top of the lifting column 32, and a drive assembly 36 for driving the lifting column 32 to rise and fall. The drive assembly 36 includes a motor 361, a rotating rod 362, a rotating wheel 363, a belt 364, and a lifting block 365, all housed within a protective box 35. The drive end of the motor 361 is connected to the rotating rod 362. The rotating wheel 363 is fixed to the rotating rod 362. The belt 364 is arranged around the rotating wheel 363. The lifting block 365 is fixedly connected to the belt 364 and to the lifting column 32. The track cleaning mechanism 7 includes a brush head 74 for cleaning the guide rail 1 and a motor 72 for driving the brush head 74 to rotate.

[0025] Reference Figure 1 and Figure 5 The track cleaning mechanism 7 is fixedly connected to the mover 2. It includes a second protective box 71, a second motor 72, a transmission rod 73, and a brush head 74. The second motor 72 is housed inside the second protective box 71. The drive end of the second motor 72 is fixedly connected to one end of the transmission rod 73, and the brush head 74 is fixedly connected to the other end of the transmission rod 73.

[0026] Reference Figure 5 The transmission rod 73 is a rod-shaped structure, and the outer circumferential surface of the brush head 74 is uniformly covered with bristles 75.

[0027] In the assembled state, the track cleaning mechanism 7 is positioned so that its bristles 75 contact the upper surface of the guide rail 1. When the mover 2 moves along the guide rail 1, the motor 2 72 drives the transmission rod 73 and the brush head 74 to rotate, and the bristles 75 rotate at high speed accordingly.

[0028] This follow-up motor-driven brush head 74 structure ensures that the guide rail 1 is automatically cleaned in real time during the robot's movement, thereby improving the stability of the mobile device 2's operation.

[0029] As a preferred embodiment, please refer to Figure 2 The lifting mechanism 3 also includes a fixing plate 33. The bottom end of the fixing column 31 is fixedly connected to the upper surface of the mover 2 through the fixing plate 33 to achieve a stable installation of the lifting mechanism 3.

[0030] As another preferred embodiment, refer to Figure 3 The lifting mechanism 3 also includes a telescopic plate 34, which is telescopically sleeved on the outside of the fixed column 31 and the lifting column 32 to protect the sliding mating part of the lifting column 32.

[0031] As another preferred embodiment, refer to Figure 3 and Figure 4 The drive assembly 36 also includes a limit rod 366 and a limit wheel 367. The limit wheel 367 is rotatably connected to one end of the limit rod 366, and the belt 364 is also arranged around the limit wheel 367. The limit wheel 367 is used to tension the belt 364.

[0032] In another preferred embodiment, the protective box 35 is fixedly connected to the mobilizer 2, and the motor 361 is housed inside the protective box 35, providing protection for the motor 361 inside.

[0033] As another preferred embodiment, refer to Figure 1 The mover 2 also includes a plurality of guide wheels 6, which are rotatably mounted on the side wall of the mover 2 and roll in contact with the side of the guide rail 1 to constrain the lateral displacement of the mover 2.

[0034] The working principle is as follows: When the inspection robot starts running, the mobile unit 2 moves along the guide rail 1 via the guide wheel 6. At this time, the lifting mechanism 3 and the track cleaning mechanism 7 start simultaneously. In the lifting mechanism 3, the motor 361 inside the protective box 35 starts and drives the rotating rod 362 to rotate. The rotating rod 362 drives the rotating wheel 363 fixed on it to rotate synchronously. The rotating wheel 363 and the limiting wheel 367 on the limiting rod 366 work together to drive the belt 364 to perform cyclical motion. The lifting block 365 fixed on the belt 364 then performs linear motion of rising or falling. Since the lifting block 365 is fixedly connected to the lifting column 32, the lifting block 365 drives the lifting column 32 to slide and rise relative to the fixed column 31, thereby driving the observer 4 and the all-round camera 5 fixed at the top of the lifting column 32 to achieve height adjustment.

[0035] As the mover 2 moves, the second motor 72 in the track cleaning mechanism 7 starts, and the second motor 72 drives the transmission rod 73 to rotate. The transmission rod 73 drives the brush head 74 at its other end to rotate, and the bristles 75 on the outer periphery of the brush head 74 rotate at high speed. The high-speed rotating bristles 75 clean the upper surface of the guide rail 1 and remove impurities. Since the track cleaning mechanism 7 is fixed on the mover 2, synchronous automatic cleaning of the entire running track is achieved. The entire process is protected by the second protective box 71, which protects the second motor 72 inside.
