Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a long-distance belt conveyor inspection device. Background Technology

[0002] Currently, in the belt conveyor industry, long-distance belt conveyors typically employ a truss-style overhead structure with maintenance access channels on both sides. Workers must walk along these access channels, and tools, equipment, and spare parts for maintenance must be manually transported. This results in high labor intensity for workers, long maintenance times, and low work efficiency. Furthermore, the maintenance access channels on both sides of the truss also lead to significant initial investment costs.

[0003] A search revealed that utility model patent document CN203781253U discloses a long-distance belt conveyor with an intelligent monitoring system, including a vehicle body, conveyor truss, drive unit, intelligent monitoring system, and control box. The intelligent monitoring system includes a remote control center, display controller, noise sensor, temperature sensor, idler speed sensor, PLC controller, GPS module, and alarm module.

[0004] However, it still has some shortcomings in its use:

[0005] The installation of the intelligent detection system mentioned above requires a lot of additional structure, time and effort, and subsequent inspection and maintenance are inconvenient. Utility Model Content

[0006] The purpose of this invention is to provide a long-distance belt conveyor inspection device that facilitates the installation and maintenance of the inspection machine without requiring excessive additional structures to support its use.

[0007] The present invention adopts the following technical solution:

[0008] A long-distance belt conveyor inspection device includes several sets of support rods, symmetrically arranged U-shaped steel rails, and an inspection machine frame. An upper idler assembly and a lower idler assembly are installed between every two support rods.

[0009] The two U-shaped steel rails are respectively fixed to several support rods arranged on both sides by bolts.

[0010] The inspection machine frame is symmetrically fixed with two sets of support frames and two sets of support rods on its front and rear sides by bolts. One end of each support rod slides within the support frame.

[0011] The outer end face of the second support rod is provided with a groove, a motor frame is slidably arranged in the groove, a drive motor is fixedly installed in the motor frame, and a roller for assisting the movement of the inspection machine frame is fixedly installed on the output shaft surface of the drive motor.

[0012] Optionally, a dual-axis motor is fixedly installed on the outer side of the inspection machine frame between the two support frames. A lead screw is rotatably installed inside the support frame. One end of the lead screw is fixed to the output shaft of the dual-axis motor. The lead screw passes through the two support rods and is threaded.

[0013] Optionally, a limit switch is fixedly installed on the inner bottom surface of the groove, and a cylinder is fixed at the end face of the motor frame inside the groove. The cylinder and the limit switch are on the same horizontal plane. A second spring is sleeved on the outer surface of the cylinder and the limit switch. One end of the second spring is fixed to the motor frame, and the other end is fixed to the inner bottom surface of the groove.

[0014] Optionally, the inspection machine frame has an internal cavity, and a mounting plate is fixedly installed below it by bolts.

[0015] Optionally, the upper surface of the inspection machine frame is symmetrically provided with inclined surfaces, and slots communicating with the inner cavity are opened on the inclined surfaces.

[0016] Optionally, U-shaped brackets are symmetrically and fixedly installed on the left and right sides of the inspection machine frame.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Please see Figure 1-6 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0031] like Figure 1As shown, a long-distance belt conveyor inspection device includes several sets of support rods 2, symmetrically arranged U-shaped steel rails 3, and an inspection machine frame 4. The support rods 2 are fixedly installed on the ground. Between every two support rods 2, an upper idler assembly 1 and a lower idler assembly 11 are installed vertically. The inspection machine frame 4 is equipped with a detection module for monitoring the upper idler assembly 1. This detection module is prior art and will not be described in detail here. The inspection machine frame 4 is positioned between two U-shaped steel rails 3, and performs motion detection on the upper idler assembly 1 along the U-shaped steel rails 3.

[0032] The upper roller assembly 1 is fixedly installed on the inner side of the two support rods 2 near the upper end by bolts, and the lower roller assembly 11 is fixedly installed on the inner side of the two support rods 2 near the lower end by bolts. Both the upper roller assembly 1 and the lower roller assembly 11 are existing technologies and will not be described in detail here.

[0033] like Figure 1 As shown, a connecting rod 21 is bolted between every two support rods 2 near the lower roller assembly 11. Two U-shaped rails 3 are bolted to several support rods 2 arranged on both sides. The U-shaped rails 3 and the connecting rods 21 are used to improve the support effect of the conveyor and ensure the stable operation of the conveyor.

[0034] like Figure 3 As shown, the inspection machine frame 4 has a cavity inside, and a mounting plate 413 is fixed to the bottom of it by bolts. The detection module can be fixed to the surface of the mounting plate 413 and then placed inside the inspection machine frame 4.

[0035] like Figure 2 As shown, inclined surfaces 41 are symmetrically arranged on the upper surface of the inspection machine frame 4. A slot 411 communicating with the inner cavity is opened on the inclined surface 41. The slot 411 is used to facilitate the installation of the camera module in the detection module.

[0036] like Figure 2 As shown, two sets of support frames 42 and two sets of support rods 44 are symmetrically fixed to the front and rear sides of the inspection machine frame 4 by bolts. A dual-axis motor 43 is fixedly installed on the outer side of the inspection machine frame 4 between the two support frames 42. The dual-axis motor 43 is existing technology and can be purchased on the market according to the required model.

[0037] like Figure 2As shown, square through slots 421 communicating with the inner cavity are provided on both the upper and lower surfaces of the support frame 42. A lead screw 431 is rotatably installed inside the support frame 42. One end of the lead screw 431 is fixed to the output shaft of the dual-axis motor 43. One end of the second support rod 44 is slidably installed inside the support frame 42 and also slides in the through slot 421, which can ensure the stability of the second support rod 44 sliding inside the support frame 42. The lead screw 431 passes through the second support rod 44 and is threaded.

[0038] Specifically, the lead screw 431 is driven to rotate by the dual-axis motor 43, which in turn drives the second support rod 44 to move laterally left and right within the support frame 42.

[0039] like Figure 2-3 As shown, a groove 441 is provided on the outer end face of the support rod 44. A motor frame 47 is slidably arranged in the groove 441. A drive motor 471 is fixedly installed in the motor frame 47. A roller for moving the auxiliary inspection machine frame 4 is fixedly installed on the output shaft surface of the drive motor 471.

[0040] like Figure 2-6 As shown, a limit switch 442 is fixedly installed on the inner bottom surface of the groove 441. A cylinder is fixed at the end face of the motor frame 47 within the groove 441. The cylinder and the limit switch 442 are on the same horizontal plane. A second spring 472 is sleeved on the outer surface of the cylinder and the limit switch 442. One end of the second spring 472 is fixed to the motor frame 47, and the other end is fixed to the inner bottom surface of the groove 441. When the second spring 472 is at its original length, there is still a distance between the cylinder and the limit switch 442. When the second spring 472 is compressed to its limit position, the cylinder presses against the limit switch 442, causing the dual-axis motor 43 to stop driving.

[0041] Specifically, the dual-axis motor 43 drives the lead screws 431 on both sides to rotate, thereby driving the support rods 44 on both sides to approach the U-shaped rails 3 on both sides, so that the rollers enter the U-shaped rails 3. When the rollers enter the inverted U-shaped rails 3 and stick to the inner wall of the U-shaped rails 3, the inner wall of the U-shaped rails 3 blocks the lateral movement of the rollers. The motor frame 47 slides in the groove 441, and the spring 472 is compressed until the cylinder presses against the limit switch 442. At this time, the dual-axis motor 43 stops driving. At this time, the inspection machine frame 4 is stably positioned between the two U-shaped rails 3 by the two sets of support rods on both sides. Then, driven by the drive motor 471, the inspection machine frame 4 moves along the U-shaped rails 3. The detection module inside the inspection machine frame 4 monitors the upper roller assembly 1.

[0042] Furthermore, by moving the two sets of support rods 44 laterally, on the one hand, the inspection machine frame 4 can be adapted to upper support roller assemblies with different spacing sizes for effective monitoring; on the other hand, it can also facilitate the separation of the inspection machine frame 4 from the U-shaped steel rail 3, making it easier for staff to complete maintenance work.

[0043] like Figure 2-4 As shown, U-shaped brackets 45 are symmetrically fixedly installed on the left and right sides of the inspection machine frame 4. Sliding rods 461 are slidably installed inside the two transverse hollow tubes of the U-shaped brackets 45. A spring 462 is fixedly connected between the end face of one side of the sliding rod 461 inside the hollow tube and the U-shaped bracket 45. Support rods are fixedly installed on the outer sides of the two sliding rods 461. Several rollers are installed on the outer side of the support plate 46. The rollers here are on the same horizontal plane as the rollers on the drive motor 471. A handle is installed on the other side of the support plate 46.

[0044] Specifically, the inspection machine frame 4 can be placed between the two U-shaped steel rails 3 by lifting the handles on both sides. Then, the sliding rods 461 on both sides are slid into the U-shaped bracket 45, so that the rollers on the support plates 46 on both sides enter the U-shaped steel rails 3. After releasing both hands, the U-shaped bracket 45 and the sliding rods 461 provide support for the inspection machine frame 4. At this time, the spring 462 in the U-shaped bracket 45 will push the sliding rod 461 against the inner wall of the U-shaped steel rail 3. After the initial support is completed, the dual-axis motor 43 can be started to move the support rod 44 closer to the U-shaped steel rails 3 on both sides, so that the rollers on the drive motor 471 enter the U-shaped steel rails 3 to provide driving force for the movement of the inspection machine frame 4.

[0045] Furthermore, by using the sliding rod 461 and the rollers on the support plate 46 to pre-support the inspection machine frame 4, it is easier to install the inspection machine frame 4 into the U-shaped steel rail 3, thereby improving the efficiency of picking up and putting down the inspection machine frame 4 and making it easier for staff to operate.
