Description

Technical Field

[0001] This utility model relates to the technical field of inspection devices, and in particular to an electromagnetic stepping inspection device. Background Technology

[0002] In the coal mining industry, coal mine belt conveyors are used. The operation of these machines requires personnel to conduct inspections to prevent malfunctions during operation. However, the inspection process is time-consuming and labor-intensive, with low efficiency, which affects the safety of machine operation.

[0003] The use of common inspection devices requires the rearrangement of the zigzag guide rails for inspection. The inspection device is usually installed above or below the belt conveyor. During the inspection process, only one side of the conveyor belt can be inspected. When the conveyor belt is in motion, the inspection device needs to be fixed for inspection. When the conveyor belt is stationary, the inspection device needs to be moved for inspection. Generally, the conveyor is set at an angle. When positioning the inspection device, its rollers need to be locked and positioned by friction. The larger the angle of inclination of the conveyor, the more difficult it becomes to move or lock the inspection device, increasing the difficulty of controlling the movement performance of the inspection device and increasing the research and development cost of the inspection device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an electromagnetic stepping inspection device to solve the problem of inconvenience in moving and locking the inspection device on an inclined conveyor.

One set of electromagnetic adsorption devices can move along the forward direction of the inspection device, and the electromagnetic adsorption devices on both ends of the inspection device can be energized at intervals to adsorb the C-shaped guide rails.

[0006] Preferably, a conductive plate is installed on the inner side of the C-shaped guide rail, and the conductive plate is insulated from the C-shaped guide rail by an insulating plate. The rollers on both sides of the inspection device are in contact with the conductive plate to conduct electricity.

[0007] Preferably, the inspection device is equipped with multiple scanning mechanisms that extend through the top and bottom of the inspection device.

[0008] Preferably, the inspection device is provided with sliding grooves on both sides. The two ends of the first set of electromagnetic adsorption devices extend from inside the inspection device into the sliding grooves on both sides of the inspection device. The inspection device is provided with a drive mechanism whose driving direction is parallel to the moving direction of the inspection device. The drive mechanism is connected to the first set of electromagnetic adsorption devices. The two ends of the second set of electromagnetic adsorption devices pass through the inspection device and are fixedly connected to the inspection device. The two sets of electromagnetic adsorption devices are arranged in parallel directions.

[0009] Preferably, the electromagnetic adsorption device includes a rod and an electromagnet. The rod has movable spaces at both ends, and a sliding rod extends outward from the movable spaces. The end of the sliding rod outside the rod is connected to the electromagnet. A controller is installed inside the inspection device and is electrically connected to the electromagnet.

[0010] Preferably, one end of the slide rod located in the movable space is connected to an abutment piece, and the slide rod is sleeved with an elastic element. The two ends of the elastic element abut the abutment piece and the rod body respectively, and the elastic element can push the abutment piece to drive the slide rod to move towards the rod body.

[0011] Compared with the prior art, the electromagnetic stepping inspection device proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0012] This invention uses two sets of electromagnetic adsorption devices that are energized at intervals, allowing the inspection device to move on the C-shaped guide rail in a forward-moving manner.

Example

[0019] Please refer to Figures 1-3This utility model proposes an electromagnetic stepping inspection device 2, including C-shaped guide rails 1 arranged on both sides of a conveyor device. The conveyor device is generally a belt conveyor, with a conveyor belt having a circular loop. The C-shaped guide rails 1 on both sides are arranged within the annular area of ​​the conveyor belt. The inspection device 2 is arranged between the two C-shaped guide rails 1. The inspection device 2, located within the annular area of ​​the conveyor belt, can simultaneously inspect the upper and lower surfaces of the inner ring of the conveyor belt. Rollers 3 are arranged on both sides of the inspection device 2 and slide within the C-shaped guide rails 1. The installation of the rollers 3 and the C-shaped guide rails 1 can restrict the inspection device 2 between the two C-shaped guide rails 1, improving the stability of the inspection device 2's operation. Electromagnetic adsorption devices 4 are arranged on both ends of the inspection device 2 in the forward direction. One set of electromagnetic adsorption devices 4 can move along the forward direction of the inspection device 2. The electromagnetic adsorption devices 4 on both ends of the inspection device 2 can be used intermittently. An electromagnetic adsorption device 1 is used; the electromagnetic adsorption device 1 is made of steel. When the inspection device 2 needs to stop, the electromagnetic adsorption device 4 installed on the inspection device 2 will operate and adsorb onto the electromagnetic adsorption device 1. The inspection device 2 can be fixed at a certain position on the electromagnetic adsorption device 1 to inspect the conveyor belt of the conveyor device. In this application, two sets of electromagnetic adsorption devices 4 are used. When the inspection device 2 needs to move, the first set of electromagnetic adsorption devices 4 continues to adsorb onto the electromagnetic adsorption device 1, and the second set of electromagnetic adsorption devices 4 stops adsorbing onto the electromagnetic adsorption device 1 and changes the distance relative to the first set of electromagnetic adsorption devices 4. At this time, the second set of electromagnetic adsorption devices 4 adsorbs onto the electromagnetic adsorption device 1, the first set of electromagnetic adsorption devices 4 stops adsorbing, and the drive mechanism 6 connected to the second set of electromagnetic adsorption devices 4 will operate to move the inspection device 2, and then adsorb the first set of electromagnetic adsorption devices 4 onto the electromagnetic adsorption device 1, so that the entire inspection device 2 stops relative to the electromagnetic adsorption device 1.

[0020] In a specific embodiment, refer to Figure 1 , Figure 2 A conductive plate 11 is installed on the inner side of the C-shaped guide rail 1. The conductive plate 11 is insulated from the C-shaped guide rail 1 by an insulating plate 12. The rollers 3 on both sides of the inspection device 2 are in contact with the conductive plate 11 to conduct electricity. The inspection device 2 needs to move between the two C-shaped guide rails 1. When the inspection device 2 is connected to the wire, the movement of the inspection device 2 may cause the wire to become tangled, which will affect the movement of the inspection device 2. Therefore, in this application, by introducing electricity into the conductive plate 11, the conductive plate 11 can conduct electricity through the rollers 3 of the inspection device 2, which can avoid the inconvenience of wire connection and improve the convenience of the movement of the inspection device 2.

[0021] In a specific embodiment, refer to Figure 1 The inspection device 2 is equipped with multiple scanning mechanisms 5, which run through the top and bottom of the inspection device 2. The scanning mechanisms 5 are used to scan the broken or damaged parts of the conveyor belt and issue an alarm in a timely manner.

[0022] In a specific embodiment, refer to Figure 1 , Figure 2 The inspection device 2 has sliding grooves 21 on both sides. The two ends of the first set of electromagnetic adsorption devices 4 extend from inside the inspection device 2 into the sliding grooves 21 on both sides. The inspection device 2 has a drive mechanism 6 whose driving direction is parallel to the moving direction of the inspection device 2. The drive mechanism 6 is connected to the first set of electromagnetic adsorption devices 4. The two ends of the second set of electromagnetic adsorption devices 4 extend through the inspection device 2 and are fixedly connected to it. The two sets of electromagnetic adsorption devices 4 are arranged in parallel directions. In this scheme, there are a total of two sets of electromagnetic adsorption devices 4. Each group has two units. When the inspection device 2 needs to move, the first group of electromagnetic adsorption devices 4 continues to adsorb onto the C-shaped guide rail 1, while the second group of electromagnetic adsorption devices 4 stops adsorbing onto the C-shaped guide rail 1 and changes its distance relative to the first group of electromagnetic adsorption devices 4. At this time, the second group of electromagnetic adsorption devices 4 adsorbs onto the C-shaped guide rail 1, and the first group of electromagnetic adsorption devices 4 stops adsorbing. The drive mechanism 6 connected to the second group of electromagnetic adsorption devices 4 will operate to move the inspection device 2, and then adsorb the first group of electromagnetic adsorption devices 4 onto the C-shaped guide rail 1, so that the entire inspection device 2 stops relative to the C-shaped guide rail 1.

[0023] In a specific embodiment, refer to Figure 3 The electromagnetic adsorption device 4 includes a rod 41 and an electromagnet 42. Movable spaces 411 are provided at both ends of the rod 41. A sliding rod 43 extends outward from the movable space 411. One end of the sliding rod 43 outside the rod 41 is connected to the electromagnet 42. A controller 7 is installed inside the inspection device 2, and the controller 7 is electrically connected to the electromagnet 42. In this design, when the electromagnet 42 at the end of the rod 41 is not energized, the sliding rod 43 and the electromagnet 42 can move into the movable space 411. When the inspection device 2 moves, the electromagnet 42 can reduce friction with the U-shaped guide rail 1, avoiding affecting the movement of the inspection device 2. When the electromagnet 42 is energized, the electromagnet can directly adsorb onto the U-shaped guide rail 1, restricting the movement of the electromagnetic adsorption device 4, and thus restricting the movement of the inspection device 2.

[0024] In a specific embodiment, refer to Figure 3 The sliding rod 43 is connected to a contact plate 45 at one end within the movable space 411. An elastic element 44 is sleeved on the sliding rod 43. The two ends of the elastic element 44 abut against the contact plate 45 and the rod body 41, respectively. The elastic element 44 can push the contact plate 45 to move the sliding rod 43 toward the rod body 41. In this scheme, the extension and retraction effect of the electromagnet 42 is actively controlled. When the electromagnet 42 is not energized, the elastic element 44 will push the sliding rod 43 and move the electromagnet 42 toward the movable space 411, which can prevent the electromagnet 42 from rubbing against the C-shaped guide rail 1. When energized, the electromagnet needs to overcome the elastic force of the elastic element 44 and attract the C-shaped guide rail 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
