[0003] The existing belt conveyor is mainly composed of rollers, roller supports and conveyor belts. During the operation of the belt conveyor, the conveyor belt may deviate due to factors such as the installation deviation of the roller supports, the quality of the conveyor belt and the unevenness of the materials. Severe deviation will cause damage to the conveyor belt and reduce the service life of the belt conveyor.

[0004] At present, during the operation of the belt conveyor, the staff is required to conduct regular inspections on the operation status of the belt conveyor. When the staff finds that the conveyor belt is deviating during the inspection, the staff will manually adjust the conveyor belt to prevent damage to the conveyor belt and ensure the normal operation of the belt conveyor. If the conveyor belt deviates during the inspection time interval, the staff cannot find it in time and cannot correct the conveyor belt in time, causing the conveyor belt to be damaged or scrapped, reducing the service life of the conveyor belt and the belt conveyor.

DETAILED DESCRIPTION

[0030] The object of the present invention is to provide a deviation correcting device to increase the service life of a belt conveyor.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 to Figure 2 As shown, an embodiment of the present invention discloses a deviation correction device for a belt conveyor, the belt conveyor comprises a roller 101, a roller support 102 for fixing the roller 101, and a conveyor belt 600 arranged above the roller 101, the deviation correction device comprises an arc track 200 and at least two roller assemblies 300, and at least two limit assemblies 400;

[0033] The roller assembly 300 is disposed below the roller support 102;

[0034] The arc track 200 is fixed at a preset position of the belt conveyor. The arc track 200 is located below the roller assembly 300 and contacts the roller assembly 300. The roller assembly 300 can move along the length direction a of the arc track 200.

[0035] The limiting assembly 400 is disposed on the arc track 200 , and the limiting assembly 400 is used to limit the movement of the roller assembly 300 in the width direction b of the arc track 200 .

[0036] The deviation correction device provided in the embodiment of the present invention has an arc track 200 fixed at a preset position of the belt conveyor, and the roller assembly 300 arranged below the roller bracket 102 can move along the length direction a of the arc track 200, and a limit assembly 400 for limiting the movement of the roller assembly 300 in the width direction b of the arc track 200 is arranged on the arc track 200. Therefore, when the conveyor belt 600 is about to deviate, the conveyor belt 600 will generate a force on the roller 101 tending to the deviation direction; when the force reaches a threshold value that can cause the roller 101 to move, the roller 101 moves under the force and the roller assembly 300. 0, the conveyor belt 600 moves in the direction of deviation along the length direction a; when the roller 101 moves, the relative movement directions of the conveyor belt 600 and the roller 101 are opposite, and the conveyor belt 600 generates a force on the roller 101 that is opposite to the movement direction of the roller 101, and the roller 101 gradually stops moving under this force, and the roller 101 generates a force on the conveyor belt 600 that is opposite to the relative movement direction of the conveyor belt 600, and the conveyor belt 600 gradually stops deviating under this force, thereby realizing automatic deviation correction of the conveyor belt 600, extending the service life of the conveyor belt 600, and further extending the service life of the belt conveyor.

[0037] It should be noted that the present invention does not limit the radius of curvature, length and width of the arc track 200. As long as the arc track can meet the use requirements, it falls within the protection scope of the present invention.

[0038] For the convenience of subsequent description, the length direction a and the width direction b of the arc track 200 are described in detail in the present invention. Figure 1 and Figure 2 As shown, the direction of the upper surface of the arc track 200 with the longest length is the length direction a, and the direction of the upper surface of the arc track 200 perpendicular to the length direction a is the width direction b.

[0039] Length direction aWidth direction bLength direction a Figure 2 As shown, the roller assembly 300 provided in the embodiment of the present invention includes two roller groups, namely a first roller group 301 and a second roller group 302. The first roller group 301 and the second roller group 302 are symmetrically arranged along the center line of the arc track 200 in the length direction a so as to balance the force of the roller assembly 300, and the first roller group 301 and the second roller group 302 have the same structure.

[0040] The first roller assembly 301 includes a first roller bracket 3012 and a first roller 3011 rotatably connected to the first roller bracket 3012. The first roller 3011 contacts the upper surface of the arc track 200 so that when the conveyor belt 600 is about to deviate, the conveyor belt 600 generates a force on the roller 101 in the direction of deviation. Under the action of the force, the roller 101 drives the first roller 3011 to move along the arc track 200 in the direction of the conveyor belt 600 tending to deviate through the roller bracket 102 and the first roller bracket 3012. When the roller 101 moves along the arc track 200, The relative movement directions of the conveyor belt 600 and the roller 101 are opposite. The conveyor belt 600 generates a force on the roller 101 in the opposite direction of the movement direction of the roller 101, so that under the force, the roller 101 drives the first roller 3011 to move along the arc track 200 in the opposite direction of the movement direction of the roller 101 through the roller bracket 102 and the first roller bracket 3012, so that the conveyor belt 600 and the roller 101 are automatically balanced, and automatic and rapid correction of the deviation of the conveyor belt 600 is realized, thereby improving the rapid response to the deviation of the conveyor belt 600 and ensuring the smooth progress of production.

[0041] Furthermore, the first roller bracket 3012 and the roller bracket 102 can be connected in a detachable manner or in a non-detachable manner, as long as the first roller bracket 3012 can be fixed to the roller bracket 102; preferably, the embodiment of the present invention adopts a detachable connection to facilitate the maintenance and replacement of the roller assembly 300.

[0042] It should be noted that the first roller bracket 3012 and the roller bracket 102 can be connected by bolts, keys or clamps, as long as the first roller bracket 3012 and the roller bracket 102 can be detachably connected.

[0043] In addition, the first roller bracket 3012 and the roller bracket 102 can be directly connected or connected through other components, as long as the connection between the first roller bracket 3012 and the roller bracket 102 can be achieved; preferably, the embodiment of the present invention adopts direct connection, which can save components and reduce costs.

[0044] Since the second roller set 302 has the same structure as the first roller set 301 , it has all the technical effects of the first roller set 301 , which will not be described in detail herein.

[0045] The roller assembly 300 provided by the present invention includes two roller groups but is not limited to two roller groups. It can also include three roller groups, four roller groups or five roller groups, etc. As long as the number of roller assemblies 300 can meet the use requirements, it falls within the protection scope of the present invention.

[0046] Furthermore, the cross-section of the arc track 200 perpendicular to the length direction a is a T-shaped, I-shaped or cross-shaped structure, etc. As long as it is a structure that cooperates with the limit assembly 400 to limit the movement of the roller assembly 300 in the width direction b of the arc track 200, it falls within the protection scope of the present invention; preferably, the embodiment of the present invention adopts a T-shaped cross-section.

[0048] And, if Figure 2 As shown, since the distance between the first side surface 2031 and the second side surface 2032 of the connecting portion 203 is smaller than the top surface width of the top 202, when the conveyor belt 600 deviates in the width direction b of the curved track 200 and generates an impact force on the correcting device along the width direction b of the curved track 200, the limiting assembly 400 will contact the lower surface of the top 202 of the curved track 200 to prevent the correcting device from tipping over on the curved track 200.

The first limit group 401 is always in contact with the first side surface 2031 of the arc track 200, and the second limit group 402 is always in contact with the second side surface 2032 of the arc track 200, so as to clamp the two sides of the arc track 200 and prevent the limit assembly 400 from moving in the width direction b of the arc track 200, thereby limiting the movement of the roller assembly 300 in the width direction b of the arc track 200.

[0050] It should be noted that the structures of the first limit group 401 and the second limit group 402 can be the same or different, as long as the first limit group 401 and the second limit group 402 cooperate with each other to limit the movement of the roller assembly 300 in the width direction b of the arc track 200; preferably, the embodiment of the present invention adopts the first limit group 401 and the second limit group 402 with the same structure, which is convenient for realizing the universalization of the component structure and facilitating maintenance and replacement.

[0058] Furthermore, the first limiting roller 4011 and the first mounting bracket 4012 are rotatably connected so that when the roller assembly 300 moves along the length direction a of the arc track 200, the first limiting roller 4011 can roll along the first side surface 2031 of the arc track 200 to prevent sliding friction between the first limiting assembly 400 and the arc track 200 and damage to the arc track 200.

[0059] It should be noted that the first limiting roller 4011 and the first mounting bracket 4012 can be connected by a pin connection, a hinge connection or a rotating joint connection, etc., as long as the first limiting roller 4011 and the first mounting bracket 4012 can be rotated.
