Description

Technical Field

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

[0002] Belt conveyors, as a type of continuous transportation equipment, are widely used in industries such as mining, ports, power, and chemicals, and are a key link in ensuring the efficient flow of materials. Due to long-term, high-load operation, conveyor belts are prone to wear, tear, and misalignment. Therefore, regular and effective condition inspections are necessary measures to prevent major accidents and ensure safe production.

[0003] To replace the high risks, low efficiency, and strong subjectivity of traditional manual inspections, inspection robots equipped with detection devices have gradually become the mainstream automated inspection solution. Inspection robots typically move along tracks laid alongside conveyors, using their onboard detection devices to scan and analyze the running conveyor belts.

[0004] However, in practical applications, it has been found that the detection devices carried by existing inspection robots have certain structural limitations. The detection modules of these devices are typically installed at a fixed angle or only have simple unidirectional (e.g., vertical lifting) adjustment capabilities. Because the conveyor belt itself has variations in width and slight positional shifts, and the critical areas to be inspected (such as belt edges, center lines, or specific repair areas) are diverse, such fixed-structure detection devices struggle to accurately align the field of view or detection point of the detection module with the target area. This results in incomplete detection coverage or loss of focus in the acquisition of critical information, severely impacting the accuracy and reliability of the inspection.

[0005] Therefore, this utility model proposes a belt detection device for inspection robots to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology of belt inspection devices for inspection robots, such as the fixed installation angle of the detection module or the single adjustment dimension, it is difficult to accurately align the detection point with different target areas on the belt, thus affecting the detection accuracy. This utility model aims to provide a belt inspection device for inspection robots with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a belt detection device for an inspection robot, comprising: a housing, a movable disk rotatably connected to the bottom of the housing, an adjustment mechanism and a detection mechanism disposed inside the housing, wherein the output end of the adjustment mechanism is connected to the detection mechanism through a linkage column; The adjustment mechanism includes a support plate fixedly connected to the bottom of the inner wall of the housing, a motor vertically arranged on the top of the support plate, a rotating shaft fixedly connected to the output end of the motor, a drive rod fixedly connected to the top of the rotating shaft, two rotating rings fixedly connected to the two ends of the drive rod, a linkage rod, a horizontally arranged cylinder, a connecting rod, a moving component, and an adjustment platform.

[0008] The motor's output end is rotatably connected to the middle of the linkage rod via a rotating shaft, a drive rod, and a rotating ring. The piston rod end of the cylinder is rotatably connected to the linkage rod via a connecting rod. The moving assembly is rotatably connected to the linkage rod and includes two moving rods, a connecting rod, and a fixed column connected in sequence. The bottom of the adjustment platform is rotatably connected to the top of the fixed column, and the top of the adjustment platform is fixedly connected to the linkage column. Through the coordinated drive of the motor and the cylinder, and the transmission of this series of linkage structures, multi-dimensional adjustment of the detection mechanism is ultimately achieved.

[0009] Preferably, the adjustment mechanism further includes two connecting plates fixedly connected inside the housing, and two adjusting rods fixedly connected between the connecting plates. The adjustment platform is slidably engaged with the two adjusting rods to provide stable guidance for the up and down movement of the adjustment platform.

[0010] Preferably, the rotation of the motor is transmitted sequentially through the rotating shaft, drive rod, rotating ring, linkage rod and moving component, ultimately driving the adjustment platform to rotate around the central axis of the fixed column.

[0011] Preferably, the extension and retraction of the cylinder drives the moving assembly via the connecting rod and the linkage rod, ultimately enabling the adjusting platform to slide up and down along the axial direction of the adjusting rod.

[0012] Preferably, the detection mechanism is a detachable structure, which includes a detection box and a fixing platform. The fixing platform is detachably installed on the top of the detection box, and the top of the fixing platform is fixedly connected to the bottom of the linkage column.

[0013] Preferably, the detection mechanism further includes two rotating columns and a threaded rod. The two rotating columns are selectively engaged with the fixed platform, and the two ends of the threaded rod are threaded to the two rotating columns respectively, for driving the two rotating columns to move towards or away from each other along their axial direction.

[0014] Preferably, the detection mechanism further includes a rotating rod and a driving column, the driving column being slidably disposed inside the rotating rod, and the rotating rod being driven to rotate by engaging the end of the threaded rod with the driving column when pushed axially.

[0015] Preferably, the side wall of the fixed platform is provided with a locking groove that matches the ends of the two rotating columns to ensure stable and reliable locking.

[0016] Preferably, the detection mechanism further includes a limiting platform and a driven column. The driven column is vertically fixed to the top of the limiting platform, and the limiting platform is fixedly connected to the bottom of the fixed platform for contacting the top of the detection box during installation to limit movement.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a rotary transmission chain driven by a motor and a lifting transmission chain driven by a cylinder, works together on the adjustment platform to drive the detection mechanism to perform compound motion. This solves the problem that existing detection devices are difficult to flexibly adjust in multiple dimensions according to the required detection position and are difficult to accurately match the detection point. It achieves the technical effect of enabling the detection mechanism to achieve multi-dimensional flexible adjustment of left and right rotation and up and down movement, thereby accurately matching different detection positions and improving the accuracy of belt detection.

[0018] 2. This utility model, by setting a threaded rod controlled by a rotating rod and a drive column, drives two rotating columns to move towards or away from each other to achieve engagement or disengagement of the fixed platform, thereby completing the installation or disassembly of the test box. This solves the problem that the replacement process of existing test modules is complicated and time-consuming after damage in harsh environments, affecting the continuous working efficiency of the equipment. It achieves the technical effect that operators only need to simply rotate and push the rotating rod to complete the quick installation and disassembly of the test box, greatly simplifying the maintenance process and improving the maintenance efficiency and service life of the test device.

Detailed Implementation

[0021] Example: Reference Figures 1 to 5 This utility model provides a belt detection device for an inspection robot, which aims to solve the structural defects in the prior art, such as the difficulty in making multi-dimensional flexible adjustments to the detection device according to the required detection position and the complexity and time-consuming replacement of the detection module.

[0022] like Figure 1 As shown, the device includes a housing 1 and a movable disk 4 rotatably connected to the bottom of the housing 1. The housing 1 serves as the basic frame and protective shell of the entire device, while the movable disk 4 is used for the device to move on the guide rail. Inside the housing 1, there is an adjustment mechanism 2 and a detection mechanism 3. The output end of the adjustment mechanism 2 is connected to the detection mechanism 3 through a linkage column 297, thereby driving the detection mechanism 3 to adjust its position and angle.

[0023] The adjustment mechanism 2 is one of the core innovations of this utility model, aiming to achieve multi-dimensional flexible adjustment of the detection mechanism 3. The adjustment mechanism 2 includes: a support plate 21, which is firmly fixed to the bottom of the inner wall of the housing 1; a motor 25 vertically mounted on the top of the support plate 21, serving as the power source for the entire adjustment device; a rotating shaft 26 fixedly connected to the output end of the motor 25, and a drive rod 27 fixedly connected to the top of the rotating shaft 26; a rotating ring 28 fixedly connected to each end of the drive rod 27, and a linkage rod 24 rotatably connected to the center of the inner wall of the rotating ring 28. This linkage rod 24 is a key component for realizing multi-stage motion transmission.

[0024] The adjusting mechanism 2 also includes a cylinder 22, which is horizontally disposed inside the housing 1. The piston rod end of the cylinder 22 is rotatably connected to the linkage rod 24 via a connecting rod 23. The extension and retraction of the cylinder 22 can drive the connecting rod 23 to swing, thereby causing the linkage rod 24 to swing.

[0025] The other end of the linkage 24 is rotatably connected to a moving component 29. The moving component 29 is a series linkage structure, including two moving rods 291, which are rotatably connected sequentially. Next, a connecting rod 292 is rotatably connected to one of the moving rods 291, and the other end of the connecting rod 292 is rotatably connected to a fixed column 293. The top of the fixed column 293 is rotatably connected to an adjusting platform 294. The bottom of the adjusting platform 294 is rotatably connected to the top of the fixed column 293, and its top is fixedly connected to the aforementioned linkage 297. Through this series of rotatable connections, the movement of the motor 25 and the cylinder 22 can be effectively transmitted to the adjusting platform 294, thereby achieving precise positioning and attitude adjustment of the detection mechanism 3.

[0026] Specifically, the rotation of motor 25 is transmitted sequentially through rotating shaft 26, drive rod 27, rotating ring 28, linkage rod 24, and moving component 29, ultimately driving the adjustment platform 294 to rotate around the central axis of fixed column 293. At the same time, the extension and retraction of cylinder 22 drives moving component 29 through connecting rod 23 and linkage rod 24, ultimately enabling adjustment platform 294 to slide up and down or swing along a specific trajectory.

[0027] Reference Figure 1 and Figure 3 The connecting plate 296 is fixedly connected to the inside of the housing 1, serving as the mounting base for the adjusting rod 295. Each connecting plate 296 has mounting holes, and is securely fixed to the inner wall of the housing 1 by bolts or other fasteners. Two adjusting rods 295 are fixedly connected between the connecting plates 296. These adjusting rods 295 are arranged in parallel and extend horizontally, and their function is to provide precise guidance and limit for the up and down movement of the adjusting platform 294.

[0028] Meanwhile, the bottom of the adjusting platform 294 has two grooves or guide holes that match the shape and size of the adjusting rod 295. In the assembled state, the adjusting platform 294 slides against the outer wall of the adjusting rod 295 through these grooves or guide holes. This sliding fit structure ensures the high stability and anti-deflection capability of the adjusting platform 294 during its up-and-down movement, guaranteeing the vertical positioning accuracy of the detection mechanism 3.

[0029] The extension and retraction of cylinder 22 is transmitted to the moving component 29 via connecting rod 23 and linkage rod 24, enabling the adjusting platform 294 to slide up and down along the axis of adjusting rod 295. This up-and-down sliding motion, combined with the rotational motion of the adjusting platform 294 itself, enables the detection mechanism 3 to achieve multi-dimensional adjustment in both the vertical and rotational directions.

[0030] Furthermore, to enable rapid replacement of the internal testing modules of the testing mechanism 3, the device is designed with a sophisticated detachable structure. This structure is another core technological concept of this invention, designed to simplify maintenance procedures and improve the device's lifespan and efficiency. The detachable structure ensures that, even in harsh environments, operators can quickly and easily complete the disassembly and assembly work when the testing modules need to be replaced.

[0031] In a preferred embodiment, the detection mechanism 3 is designed with a quick-disassembly and replacement structure for easy maintenance in harsh environments. The detection mechanism 3 includes a detection box 31 with a mounting platform 35 detachably mounted on its top. The top of the mounting platform 35 is fixedly connected to the bottom of the linkage column 297, ensuring that the detection box 31 can move with the adjustment mechanism 2. The detection box 31 contains the actual detection module, such as an optical sensor or ultrasonic sensor, for belt detection. When the detection module needs to be replaced, the entire detection box 31, along with the mounting platform 35, can be removed.

[0032] In another preferred embodiment, to enable rapid engagement and disengagement between the fixed platform 35 and the detection box 31, the detection mechanism 3 further includes two rotating columns 32 and a threaded rod 33. The rotating columns 32 are columnar, with threaded holes on their outer surfaces that match the threads of the threaded rod 33. Both ends of the threaded rod 33 are threadedly connected to the two rotating columns 32, and rotation of the threaded rod 33 can drive the two rotating columns 32 to move towards or away from each other along their axial direction.

[0033] In another preferred embodiment, to facilitate manual operation of the threaded rod 33, the detection mechanism 3 further includes a rotating rod 37 and a drive column 38. The drive column 38 is slidably disposed inside the rotating rod 37. The outer end of the rotating rod 37 is usually provided with a handle or knob for easy gripping and rotation by the operator. When the rotating rod 37 is pushed in axially, the drive column 38 inside it engages with the end of the threaded rod 33. At this time, rotating the rotating rod 37 will drive the threaded rod 33 to rotate via the drive column 38. When fixing is required, the threaded rod 33 is rotated in the opposite direction to cause the rotating column 32 to lock onto the fixing platform 35. When unlocking is required, the threaded rod 33 is rotated clockwise to move the rotating column 32 away from the fixing platform 35. After rotation is completed, the rotating rod 37 is pulled outward, and the drive column 38 disengages from the threaded rod 33, thereby locking the position of the rotating column 32 and preventing accidental movement.

[0034] In another preferred embodiment, to ensure a secure engagement between the rotating column 32 and the fixed platform 35, the side wall of the fixed platform 35 is provided with engagement grooves that match the ends of the two rotating columns 32. When the rotating columns 32 move toward each other, they are precisely inserted into and engaged in these engagement grooves, thereby firmly fixing the fixed platform 35 inside the detection box 31 and preventing it from loosening or falling off during use.

[0035] In another preferred embodiment, to provide accurate positioning during the installation of the detection box 31, the detection mechanism 3 further includes a limiting platform 34 and a driven post 36. The driven post 36 is vertically fixed to the top of the limiting platform 34, which is fixedly connected to the bottom of the fixing platform 35. During installation of the detection box 31, the operator pushes the detection box 31 upwards until the top of the detection box 31 contacts the limiting platform 34. At this point, the limiting platform 34 provides a physical stop, indicating that the detection box 31 has reached the correct installation position, preventing excessive installation or positional deviation, thereby ensuring accurate alignment and locking of the locking mechanism.

[0036] The working principle is as follows: When the belt needs to be inspected, the movable disc 4 moves the entire device on the preset guide rail. When left and right rotation adjustment is required, the motor 25 inside the adjustment mechanism 2 starts, and the motor 25 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the drive rod 27 at its top and the rotating rings 28 at both ends of the drive rod 27 to rotate synchronously. The rotating rings 28 then drive the linkage rod 24 rotatably connected to its inner wall to rotate. The rotation of the linkage rod 24 is transmitted through the rotatably connected movable component 29, that is, through the movable rod 291, the connecting rod 292 and the fixed column 293 in sequence, and finally drives the adjustment platform 294 rotatably connected to the top of the fixed column 293 to rotate around the central axis of the fixed column 293. Since the top of the adjustment platform 294 is fixedly connected to the linkage column 297, and the linkage column 297 is connected to the detection mechanism 3, the horizontal rotation adjustment of the detection mechanism 3 is realized.

[0037] When vertical position adjustment is required, the piston rod of the cylinder 22 inside the adjustment mechanism 2 extends or retracts. The cylinder 22 pushes or pulls the linkage rod 24 through the rotating connecting rod 23, causing the linkage rod 24 to swing. The swing of the linkage rod 24 also drives the adjustment table 294 through the moving component 29. At this time, the adjustment table 294 slides up and down along the axis of the adjustment rod 295 under the guidance and limiting action of the adjustment rod 295 fixed between the connecting plates 296. The up and down sliding of the adjustment table 294 drives the linkage column 297 and the detection mechanism 3 to rise and fall synchronously, thereby realizing the vertical position adjustment of the detection mechanism 3. Through the coordinated work of the motor 25 and the cylinder 22, the problem of the detection device being difficult to flexibly match the detection position is solved.

[0038] When the detection box 31 inside the detection mechanism 3 needs to be replaced due to damage, the operator first pushes the rotating rod 37 axially, so that the drive column 38 inside it engages with the end of the threaded rod 33. Then, the operator rotates the rotating rod 37, and the drive column 38 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 drives the two rotating columns 32 threadedly connected to its two ends to move away from each other along the axial direction of the threaded rod 33, that is, to retract to both sides, so that the ends of the two rotating columns 32 disengage from the locking groove on the side wall of the fixed platform 35. At this time, the locking between the fixed platform 35 and the detection box 31 is released, and the operator can then remove the fixed platform 35 together with the limiting platform 34 at its bottom and the driven column 36 from the groove at the top of the detection box 31 to complete the disassembly.

[0039] When installing the new test box 31, the operator aligns the groove on the top of the test box 31 with the fixing platform 35 and pushes it upwards until the top of the test box 31 contacts the bottom of the limiting platform 34. At this time, the limiting platform 34 plays a precise positioning role. Then, the operator rotates the rotating rod 37 in the opposite direction, and the drive column 38 drives the threaded rod 33 to rotate in the opposite direction, so that the two rotating columns 32 move towards each other until their ends are inserted into and locked in the locking groove of the fixing platform 35. When the rotating rod 37 feels resistance, it means that it has been locked. Finally, the operator pulls the rotating rod 37 outwards to disengage the drive column 38 from the threaded rod 33 and prevent the threaded rod 33 from rotating accidentally. This completes the quick replacement of the test box 31. The structure solves the problem of complicated test module replacement process.
