Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of belt conveyors, in particular to a device and method for automatically adjusting the deviation of a belt conveyor. BACKGROUND

[0002] A device for automatically adjusting the deviation of a belt conveyor generally uses a sensor to detect belt deviation (such as a photoelectric sensor or a mechanical touch wheel), and through a control system to analyze the deviation signal and drive the adjusting mechanism (such as a hydraulic cylinder, an electric push rod or a rotating roller frame) to make real-time correction. For example, when the belt deviates, the contact detection wheel triggers the hydraulic system to push the centering roller to rotate, so that it forms an angle with the movement direction of the belt, generating a transverse friction force to push the belt back to the center position. Some devices also combine link mechanisms or spiral rollers to achieve power-free adjustment using self-feedback force when the belt deviates. Such devices can effectively reduce manual intervention, prolong the service life of the belt, and are suitable for conveying systems in mining, metallurgy and other industries.

[0003] For example, the prior art patent No. CN206218642U discloses a belt conveyor, which comprises a driving roller 1 and a driven roller 2 supported by a frame, and a belt 3 sleeved on the driving roller 1 and the driven roller 2. The belt conveyor further comprises a supporting plate 4 mounted on the frame, which is located below the upper layer of the belt between the driving roller 1 and the driven roller 2. The supporting plate 4 guides the belt 3 through an anti-deviation structure. The belt conveyor can effectively prevent the belt from deviating when under heavy load or uneven feeding, ensuring the stability of belt conveying and improving the carrying capacity of the belt.

[0004] The problem with the above-mentioned prior art is that although it can solve the problem of belt deviation to some extent, it cannot create a concave shape on the surface of the belt while solving the problem of deviation, resulting in the material being easily dropped from the sides of the belt into the gap of the equipment when conveying easily rolling materials, causing damage to the equipment.

The first lead screw (9) and the second lead screw (10) are symmetrically distributed at the front and rear ends of the transmission roller (4). The adjacent ends are hinged to the inner wall of the working chamber (7), and the other ends are respectively hinged to the front and rear ends of the transmission roller (4). The first lead screw (9) and the second lead screw (10) are both provided with an adjusting block (11) that is slidably connected to the inner wall of the transmission roller (4). The slider (6) is fixed to the outer wall of the adjusting block (11). The drive rod (12) is connected to the drive source. The top of the drive rod is fixed to the first gear (13), and the bottom of the drive rod is hinged to the bottom of the inner wall of the working cavity (7) via the telescopic rod (14). The first gear (13) is provided with a second gear (15) and a third gear (16) on both sides. The bottom of the second gear (15) and the third gear (16) are respectively fixed to the first bevel gear (17) and the second bevel gear (18). The first lead screw (9) is provided with a third bevel gear (19) near the second gear (15) to mesh with it. The second lead screw (10) is provided with a fourth bevel gear (20) near the second bevel gear (18) to mesh with it. A fourth gear (22) driven by a motor (21) is provided on the side of the drive rod (12), and a fifth gear (23) meshing with the fourth gear (22) is fixedly connected to the middle of the drive rod (12); a first limiting plate (24) is provided above and below the first gear (13) to abut against the upper and lower ends of the third gear (16), so that the drive rod (12) and the third gear (16) move synchronously; a rotating shaft (28) in the middle of the third gear (16) is fixedly connected to a second bevel gear (18) and a synchronous disk (25) with a first synchronous groove (26), and a first synchronous block (27) adapted to the first synchronous groove (26) is provided at its bottom. A sixth gear (29) is provided on the rotating shaft (28), which meshes with the fifth gear (23) via the seventh gear (30). The seventh gear (30) is provided with a second limiting plate (31) at the top and bottom to abut against the upper and lower ends of the sixth gear (29) and the fifth gear (23), so that the seventh gear (30) and the sixth gear (29) move synchronously when the drive rod (12) rises and falls. A limiting groove (32) is opened in the middle of the rotating shaft (28) for the sixth gear (29) to slide. A second synchronizing block (33) is provided at the top of the limiting groove (32) to match the second synchronizing groove (34) at the top of the sixth gear (29).

2. The belt conveyor deviation adjustment device as described in claim 1, characterized in that: The top of the working chamber (7) is provided with an inspection port, and an inspection door (8) is installed on the upper part of the inspection port. The inspection door (8) is hinged to the side wall of the inspection port, and a displacement sensor (36) is connected to the outer wall of the inspection door (8).

3. A method for automatically adjusting the belt conveyor's misalignment, employing the belt conveyor misalignment device described in any one of claims 1-2, characterized in that... Includes the following steps: S1. When the conveyor belt (1) deviates, the relative sliding displacement of the sliders (6) on both sides of the transmission roller (4) in the groove (5) is controlled so that the protruding ends of the two sliders (6) form an asymmetrical support structure. S2. The portion of the slider (6) protruding from the surface of the transmission roller (4) generates a radial constraint force on the conveyor belt (1), so that the conveyor belt (1) forms a controlled recessed area on the surface of the transmission roller (4). S3. By adjusting the dynamic combination of the sliding direction and sliding distance of the sliders (6) on both sides, the force distribution state of the conveyor belt (1) is changed in real time, thereby realizing the closed-loop adjustment of the deviation angle of the conveyor belt (1).
