Description

Technical Field

[0001] The present invention relates to the technical field of inspection robots, and specifically to an extended-range inspection robot under a belt. Background Art

[0002] In scenarios such as power stations, mines, and coal mines, conveyor belts are key equipment, and their operating status directly affects production efficiency and safety. However, these scenarios often have harsh environmental characteristics such as high temperature, high pressure, high noise, and high dust, making the traditional manual inspection method inefficient and posing safety hazards. With the progress of technology, the application of inspection robots has become a trend. Inspection robots, with their unique rail-mounted design or autonomous movement ability, can stably and efficiently operate along preset tracks or autonomous paths, covering all key parts of the belt conveyor. They can real-time monitor key parameters such as the temperature, vibration, and noise of the belt, and judge the health status of the belt through intelligent analysis algorithms, timely discover and warn of potential faults.

[0003] At the present stage, during the use of inspection robots, inspection robots are often directly installed above or below the belt. By moving the inspection robot along the preset track, the upper and lower parts of the belt can be monitored. However, in a continuously operating conveyor system, the inner wall of the belt often bears risks such as abrasion, corrosion, and possible internal tearing caused by direct contact with materials. At the same time, idlers, as the core components supporting the operation of the belt, often have problems such as wear, fracture, or insufficient lubrication. Existing inspection robots have deficiencies in the monitoring range, making it difficult to timely capture potential problems in key parts such as the inner wall of the conveyor belt and idlers, which may affect the stability and safety of the entire production process. In view of this, we propose an extended-range inspection robot under a belt. Summary of the Invention

[0021] In this embodiment, a mounting plate 402 is also fixedly connected to the center of the inner bottom of the body 40 by bolts. The first motor 44 is fixedly connected to the mounting plate 402 by bolts. The mounting plate 402 plays a role in stably supporting and fixing the first motor 44.

[0022] In this embodiment, the movable plate 493 and the limiting plate 494 are integrally formed structures. The size of the movable plate 493 is adapted to the size of the connection groove 4901. The integrated design of the movable plate 493 and the limiting plate 494 enhances the overall strength of the structure, and improves the durability and stability of the equipment.

[0023] In this embodiment, positioning grooves 560 are formed on both side walls inside the opening of the mounting frame 56. Positioning blocks 580 are fixed to both outer walls of the frame 58.

[0026] It can be understood that one end of the double-headed lead screw 491 in this embodiment is coaxially key-connected with an adjusting head 492, and the cross-sectional shape of the adjusting head 492 is regular hexagon.

[0029] In addition, a plurality of wires are also passed through between the machine body 40 and the box body 50 in this embodiment. Through the wires, the power of the battery module 54 is conveniently transmitted into the machine body 40, so as to provide a stable power source for the operation of devices such as the first motor 44.

[0030] It is worth noting that the first motor 44 and the second motor 47 involved in this embodiment are existing conventional technologies and will not be elaborated here.

[0031] During specific use, the user first turns on the power of the first motor 44, and the first motor 44 starts to work. The output shaft of the first motor 44 rotates to drive the first bevel gear 440 to rotate. Since the first bevel gear 440 meshes with the second bevel gear 450, the rotating shaft 45 rotates synchronously and drives the two side gears 46 to rotate. Since the gears 46 mesh with the rack 31, the gears 46 move horizontally along the rack 31. At the same time, the machine body 40 moves to one side along the two guide plates 30. At the same time, the machine body 40 drives the box body 50 to move horizontally. The friction power generation wheel 52 simultaneously rubs against the belt 1 and rotates, and the friction power generation wheel 52 converts mechanical energy into electrical energy and stores it in the battery module; when the machine body 40 moves horizontally, the high-definition camera 433 and the infrared camera 434 continuously capture and transmit detailed images of the inner wall of the belt 1 and the idler rollers, and the ultrasonic radar 6 simultaneously uses ultrasonic waves to perform non-contact measurement and detection on the inner wall of the belt 1; When the box body 50 needs to be disassembled, the user first rotates the adjusting head 492, then the double-headed lead screw 491 rotates and drives the two movable plates 493 to move relatively inward along the connecting groove 4901. The movable plates 493 drive the limiting plates 494 to move at the same time, and the limiting plates 494 are disengaged from the fixing grooves 551, and the restriction of the limiting plates 494 on the inserting plates 550 is released. Finally, the user pulls the box body 50 backward, and the connecting plate 55 drives the inserting plates 550 to disengage from the inserting slots 4902, and the box body 50 is disassembled.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
