[0028] like Figure 1-Figure 4 As shown, in one embodiment, an automatic deviation-correcting device for a belt conveyor includes: a main support structure 1, a position-limiting support structure 2, a rotation deviation-correcting structure 3 and a transverse deviation-correcting structure 4. The main support structure 1 and the position-limiting support structure 2 are arranged in parallel on the middle frame of the conveyor, the main support structure 1 is detachably provided with the rotation deviation-correcting structure 3, the position-limiting support structure 2 is detachably provided with the transverse deviation-correcting structure 4, and the rotation deviation-correcting structure 3 and the transverse deviation-correcting structure 4 form a linkage flexible automatic deviation-correcting device for automatically correcting the belt.

[0029] like Figure 1-Figure 4 As shown, in this embodiment, the main support structure 1 is composed of a first vertical support 5, a first transverse support 6 and a connecting steel plate 7, and the first vertical support 5 forms a U-shaped frame structure by connecting the steel plate 7 and the first transverse support 6. The upper part of the first vertical support 5 is fixed to the middle frame of the conveyor by bolts, and the first transverse supports 6 are symmetrically arranged on both sides. The first transverse support 6 is connected to the lower part of the first vertical support 5 by bolts.

[0030] Furthermore, a connecting steel plate 7 is welded to the middle of the first transverse support 6, and the connecting steel plate 7 is connected to the fixed surface of the slewing bearing 11 on the rotation correction structure 3 by bolts. Specifically, the first vertical support 5 and the connecting steel plate 7 are symmetrically arranged in two groups.

[0031] like Figure 1-Figure 4 As shown, in this embodiment, the position limiting support structure 2 is supported by a second vertical support 8, a second horizontal support 9 and a notched steel plate 10, and the second vertical support 8 forms a U-shaped frame structure through the notched steel plate 10 and the second horizontal support 9. Among them, the upper part of the second vertical support 8 is also fixed to the middle frame of the conveyor by bolts, and the notched steel plate 10 is welded in the middle of the second horizontal support 9, and the notched steel plate 10 is used to limit the movement range of the lateral deviation correcting structure 4. Specifically, the second vertical support 8 and the notched steel plate 10 are symmetrically arranged in two groups.

[0032] like Figure 1-Figure 4 As shown, in this embodiment, the rotation correction structure 3 includes a slewing bearing 11, a first bracket 12, a roller 13 and a hinge 14. The rollers 13 are symmetrically arranged above the first bracket 12. The bottom of the first bracket 12 is connected to the rotating surface of the slewing bearing 11 by bolts, and the fixed surface of the slewing bearing 11 is connected to the connecting steel plate 7 by bolts. A hinge 14 is installed on one side of the first bracket 12, and the hinge 14 is connected to the middle circular hole of the second bracket 15 by a pin shaft, so that the first bracket 12, the rollers 13 and the hinge 14 can rotate around the slewing bearing 11, and the entire rotation correction structure 3 can rotate around the pin shaft.

[0033] like Figure 1-Figure 4 As shown, in this embodiment, the lateral correction structure 4 is composed of a second bracket 15, a vertical roller 16 and a limit pin 17. The middle part of the second bracket 15 is connected to the hinge 14, and limit pins 17 are arranged on both sides of the bottom of the second bracket 15. The limit pin 17 moves within the notch range of the notch steel plate 10.

[0034] The linkage-type four-link flexible automatic deviation correction device composed of a rotary deviation correction device and a lateral deviation correction device can effectively protect the belt edge from damage. The overall structure of the device is simple, which can meet the use requirements of various types of belt conveyors. The parts are highly interchangeable, easy to maintain and overhaul, and effectively reduce production costs and maintenance cycles.

[0035] Working principle: When in use, the deviation correction device is installed about three times the width of the belt in front of the tail redirection roller or tensioning device where the belt is prone to deviation. The first vertical support 5 and the second vertical support 8 are fixed to the middle frame of the belt conveyor according to the size, so that they act on the return surface of the belt. When the return belt deviates:

[0036] (1) The lateral displacement resistance of the belt will drive the roller 13 to rotate and move laterally in the deviation direction, and the roller 13 will drive the slewing bearing 11, the bracket, the hinge 14, etc. to rotate and move in the deviation direction, thereby forming a certain angle with the movement direction of the belt; at this time, the return belt will be pushed back to the center position because of the large friction force on the roller 13 in the deviation direction;

[0037] (2) After the belt contacts the vertical roller 16 in the lateral deviation correction structure 4, the vertical roller 16 will apply a balanced lateral force to the deviated belt, so that it is always in the center state, and the linkage four-link flexible automatic deviation correction device will not cause damage to the edge of the belt;

[0038] (3) The limit pin 17 in the transverse correction structure 4 will move in the groove on the groove steel plate 10 in the limit support structure 2. When the transverse correction structure 4 reaches the maximum limit, the belt deviation is more serious, and the lateral displacement resistance of the belt will immediately increase to prevent the belt from further deviation.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
