Description

Technical Field

[0001] The utility model relates to the field of bulk material conveyor belts, and in particular to an intelligent automatic belt deviation rectifying device for bulk material conveyor belts. Background Art

[0002] Belt conveyor systems are widely used in industries such as coal, power, chemical, ports, docks, steel, and building materials. During the operation of a belt conveyor system, belt deviation is a common system fault, which seriously affects the stability and operating efficiency of the system, and may even lead to operating safety accidents in severe cases.

[0003] Deviation rectifying devices are widely used in related fields of bulk material conveyor belts. Traditional deviation rectifying devices usually correct the belt through the friction force difference on both sides generated by the angle between the idler group and the belt.

[0004] At present, due to problems such as wear on the side of the on-site belt, inconsistent wear of the idlers on both sides of the deviation rectifying device caused by foreign objects on the on-site belt, and strong on-site wind, the traditional deviation rectifying device often has poor deviation rectifying effect and low deviation rectifying efficiency during the deviation rectifying process.

Since the positive idler and the side idler are in contact with the upper belt, and the positive idler and the side idler form a certain angle with the running direction of the upper belt, the frictional force generated during the running process can enable the positive idler and the side idler to form deviation correction forces simultaneously, and thus the upper belt can be quickly corrected. By using this method for deviation adjustment, the deviation adjustment effect can be better and the deviation adjustment efficiency can be higher. Description of the Drawings

The protective cover 41 and the cover plate 42 can prevent water from directly contacting the electric push rod 46, playing a role in protecting the electric push rod 46.

[0038] In this embodiment, an opening 48 is provided on the left side of the bottom of the protective cover 41, and an exhaust air plate 49 is provided on the opening 48, which can facilitate ventilation.

[0039] In this embodiment, a through hole 410 is provided at the left end of the protective cover 41, and a wire conduit joint 411 is installed on the through hole 410. The wire of the electric push rod 46 passes through the wire conduit joint 411 and is connected to the control mechanism 9, which can better complete the connection between the electric push rod 46 and the control mechanism 9, protect the wire and ensure electrical safety.

[0040] In this embodiment, the rotating mechanism 5 includes a bearing seat 51, a rotating shaft 52, a connecting plate 53 and a connecting boss 54. The connecting boss 54 includes an integrally formed connecting portion 541 and a protruding portion 542. The bearing seat 41 is sleeved in the mounting groove 33. The rotating shaft 52 is sleeved in the bearing seat 51. The connecting plate 53 and the connecting portion 541 are sequentially sleeved on the upper end of the rotating shaft 52 from bottom to top. The protruding portion 542 is connected to the other end of the connecting rod 47. The center of the bottom of the idler support assembly 6 is fixed on the connecting portion 541. The rotating shaft 52 can rotate in the bearing seat 51. The rotation of the rotating shaft 52 can drive the connecting portion 541 and the protruding portion 542 to rotate accordingly, so as to achieve the rotating effect. The rotating mechanism 5 further includes a limit baffle 55. One end of the limit baffle 55 is fixed to one end of the bearing seat 51, and the other end is inserted into the positive idler support 61 for limiting.

[0041] In this embodiment, the idler support assembly 6 includes a positive idler support 61 for installing the positive idler 7 and two side idler supports 62 for installing the side idlers 8. The positive idler support 61 is horizontally arranged, and the center of the positive idler support 61 is fixed on the connecting portion 541. The two side idler supports 62 are obliquely arranged on both sides of the positive idler support 61.

[0042] In this embodiment, the control mechanism 9 includes a controller 91, a control box 92 and a bracket 93. The control box 92 is fixed to a belt center frame 203 through the bracket 93. The controller 91 is installed in the control box 92, and the controller 91 is respectively connected to the electric push rod 46 and the server 10. Specifically, the controller 91 is a PLC controller.

[0043] The working principle of the present utility model is as follows:

[0044] The camera 2 captures the running image of the upper belt 201 in real time and sends it to the server 10. The server 10 monitors and analyzes the running state of the upper belt 201, determines whether the upper belt 201 runs off track, and calculates the amount of deviation.

[0045] When the upper belt 201 deflects to the left, as Figure 9As shown, after the server 10 calculates the deviation amount, it determines the deviation correction amount and the deviation correction direction and converts them into electrical signals to be transmitted to the controller 91. The controller 91 controls the electric push rod 46 to move to the left according to the electrical signal. After the electric push rod 46 moves, it drives the protruding part 542 to rotate clockwise by a certain angle around the rotating shaft 52. At the same time, the connecting part 541 also rotates clockwise, thereby driving the positive idler bracket 61 fixed on the connecting part 541 to rotate clockwise. Furthermore, the positive idler 7 and the side idler 8 also rotate clockwise. Since the positive idler 7 and the side idler 8 are in contact with the upper belt 201, the positive idler 7 and the side idler 8 form a certain angle with the running direction of the upper belt 201. Through the frictional force generated during the running process, the positive idler 7 and the side idler 8 can simultaneously form a deviation correction force, and thus the upper belt 201 can be quickly corrected. After the upper belt 201 is corrected, it returns to the initial position.

[0046] On the contrary, when the upper belt 201 is deflected to the right, as Figure 10 shown, after the server 10 calculates the deviation amount, it determines the deviation correction amount and the deviation correction direction and converts them into electrical signals to be transmitted to the controller 91. The controller 91 controls the electric push rod 46 to move to the right according to the electrical signal. After the electric push rod 46 moves, it drives the protruding part 542 to rotate counterclockwise by a certain angle around the rotating shaft 52. At the same time, the connecting part 541 also rotates counterclockwise, thereby driving the positive idler bracket 61 fixed on the connecting part 541 to rotate counterclockwise. Furthermore, the positive idler 7 and the side idler 8 also rotate counterclockwise. Since the positive idler 7 and the side idler 8 are in contact with the upper belt 201, the positive idler 7 and the side idler 8 form a certain angle with the running direction of the upper belt 201. Through the frictional force generated during the running process, the positive idler 7 and the side idler 8 can simultaneously form a deviation correction force, and thus the upper belt 201 can be quickly corrected. After the upper belt 201 is corrected, it returns to the initial position.

[0047] The above are only some embodiments of the present invention, and thus do not limit the protection scope of the present invention. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
