[0023] The following further describes in detail the embodiments of this utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate this utility model, but cannot be used to limit the scope of this utility model.

[0024] Such as Figures 1 to 5As shown in the figure, a deviation adjusting device and a belt conveyor include a device frame 1 and a detection and driving assembly 2. The detection and driving assemblies 2 are symmetrically installed on both sides of the front end of the device frame 1. A deviation rectifying oil cylinder assembly 3 is arranged on the front side of the device frame 1. A deviation rectifying roller frame 4 is horizontally installed in the middle of the device frame 1. The detection and driving assembly 2 includes a detection and driving wheel 201, an oil pump 202, a connection valve 203, an electric slewing frame 204, and an electric slider 205. The bottom of the detection and driving wheel 201 is connected to the oil pump 202 through a coupling. Two groups of connection valves 203 are installed on the side of the oil pump 202. An electric slewing frame 204 is installed at the rear side of the oil pump 202. An electric slider 205 is installed on the side of the electric slewing frame 204 away from the oil pump 202. The device frame 1 includes a mounting seat 101, a self-aligning support 102, a swing bracket 103, a track frame 104, and a support frame 105. The self-aligning support 102 is installed in the middle of the mounting seat 101. A swing bracket 103 is horizontally connected to one side of the lower end of the self-aligning support 102. Track frames 104 are installed at the left and right ends of the mounting seat 101. A support frame 105 is arranged on one side of the self-aligning support 102. The side of the electric slider 205 away from the electric slewing frame 204 is slidably connected to the surface of the track frame 104. The track frame 104 and the mounting seat 101 are fixedly connected. By using the sliding connection between the electric slider 205 and the surface of the track frame 104 connected to the front side vertical surface of the mounting seat 101, the entire detection and driving assembly 2 can be vertically slidably adjusted along the front side vertical surface of the track frame 104. Through the rotational adjustability of the structure of the electric slewing frame 204 itself, the entire oil pump 202 and the detection and driving wheel 201 connected to its top can swing left and right within a certain angle range in the vertical direction with the electric slewing frame 204 itself as the center.

[0025] As Figures 1 to 5As shown in the figure, the deviation rectifying oil cylinder assembly 3 includes a deviation rectifying cylinder body 301, a reversing valve 302 and oil pipes 303. The reversing valve 302 is installed on the side surface of the deviation rectifying cylinder body 301, and two groups of oil pipes 303 are connected to both the left and right sides of the reversing valve 302. The output end of the deviation rectifying cylinder body 301 is connected to the swing bracket 103, and one end of the deviation rectifying cylinder body 301 away from the swing bracket 103 is connected to the support frame 105. Moreover, one end of the oil pipe 303 away from the reversing valve 302 is connected to the connection valve 203. The deviation rectifying roller frame 4 includes a roller body 401, an anti-slip pad 402, a bearing bracket 403 and a stabilizing frame 404. The surface of the roller body 401 is covered with the anti-slip pad 402, and bearing brackets 403 are connected to both the left and right ends of the roller body 401. Moreover, a stabilizing frame 404 is connected to the bottom of the bearing bracket 403. The center of the bottom of the stabilizing frame 404 is fixedly connected to the centering bracket 102, and the bearing bracket 403 and the stabilizing frame 404 are welded together. By using the centering bracket 102, the entire deviation rectifying roller frame 4 has sufficient structural stability while rotating and adjusting. At the same time, in cooperation with the anti-slip pad 402 covered on the surface of the roller body 401, when the roller body 401 comes into structural contact with the surface of the conveyor belt, it has sufficient friction, so as to carry out deviation rectifying adjustment for it in the shortest time.

[0026] A belt conveyor is installed with the deviation rectifying device as described above. By installing track frames 104 at both ends of the mounting seat 101, the inspection and driving assembly 2 is slidably connected to them by means of electric sliders 205, so that within a certain adjustment range, the entire inspection and driving assembly 2 can be adjusted vertically up and down. The electric rotary frame 204 can make the entire inspection and driving assembly 2 swing left and right within a certain range in the vertical direction. By using the above structure, flexible adjustment can be carried out while making flexible deviation rectifying adjustment for the conveyor belt to ensure the self-stability of the conveyor belt.

[0027] In summary, as Figures 1 to 5 shown in the figure, when the deviation rectifying device and the belt conveyor are in use, first, according to the usage requirements, the inspection and driving assembly 2 connected to the surfaces of the track frames 104 at both ends of the mounting seat 101 can be appropriately adjusted. First, use the electric slider 205 to make the entire inspection and driving assembly 2 slide vertically along the front side elevation of the track frame 104, and then through the rotational adjustability of the structure of the electric rotary frame 204, make the entire oil pump 202 and the inspection and driving wheel 201 connected to its top swing left and right within a certain angle range in the vertical direction with the electric rotary frame 204 itself as the center, so as to ensure that the edge of the conveyor belt can come into structural contact with the inspection and driving wheel 201 under appropriate circumstances;

[0028] When the conveyor belt passing over the anti-slip pad 402 on the surface of the roller body 401 runs off to one side, the edge of one side of the conveyor belt moving rapidly at this time will come into structural contact with the surface of the inspection drive wheel 201 in the inspection drive assembly 2 on one side of the device frame 1. At this time, under the action of friction, the inspection drive wheel 201 will rotate axially. Since the inspection drive wheel 201 is connected to the oil pump 202 through a coupling, this will drive the internal structure of the oil pump 202 to rotate. Then, under the operation of the oil pump 202, through the oil pipe 303 at one end of the connection valve 203, and in cooperation with the operation of the reversing valve 302, the hydraulic oil at one end inside the deviation rectifying cylinder body 301 is conveyed to the other end, so as to realize the structure expansion and contraction of the deviation rectifying cylinder body 301.

[0029] With the structure expansion and contraction of the deviation rectifying cylinder body 301, it will drive the swing bracket 103 at one end to move in the horizontal direction, and further drive the centering bracket 102 to swing left and right in the horizontal direction, thereby making the entire deviation rectifying roller frame 4 connected to it rotate synchronously in the horizontal direction. At this time, the roller body 401 will form an angle with the conveyor belt moving at high speed in the horizontal direction and generate a frictional force to one side, so as to drive the conveyor belt to shift towards the middle of the stable frame 404 where the roller body 401 is installed by itself, so that the entire conveyor belt always runs within a certain range, ensuring the normal operation of the entire belt conveyor.

Many modifications and variations are obvious to those of ordinary skill in the art.
