Description

Technical Field

[0001] The invention relates to the technical field of belt conveyor deviation correction, in particular to a roller deviation correction structure and a belt conveyor thereof. Background Art

[0002] Belt conveyor is a kind of conveying equipment, which transports materials by continuous motion and is widely used in mining, metallurgy, coal and other industries. It is mainly composed of frame, conveyor belt, roller, roller, tensioner, transmission device and other components. The working principle of belt conveyor is based on the principle of friction transmission. The traction force is transmitted through the friction between the drive roller and the conveyor belt, so as to realize the continuous transportation of materials. The conveyor belt relies on the friction between the drive roller and the conveyor belt to drag and transport the materials from the feeding point to the unloading point.

[0003] Rollers are important components of belt conveyors, used to support the weight of conveyor belts and materials.

[0004] When using rollers to transport materials, the conveyor belt on the belt conveyor is prone to deviation along the length direction of the roller. When the conveyor belt deviates and is not corrected in time, the conveyor belt and equipment are easily worn, greatly increasing the cost of use and shortening the service life of the conveyor belt. The current correction method is to add additional correction rollers, and use the correction rollers to generate force on the conveyor belt along the length direction of the roller to restore the conveyor belt to its original position to achieve the purpose of correction. However, the conveyor belt will be concave and deformed at the contact point between the correction roller and the conveyor belt, and the conveyor belt cannot be corrected well, which is not conducive to normal use of transportation.

DETAILED DESCRIPTION

[0039] 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.

[0040] like Figure 1-Figure 12 As shown, an embodiment of the present invention provides a roller deviation correction structure, comprising:

The side surface is an inclined surface, which is lower than the contact ball 205. The sliding rod 202 and the short rod 206 are fixedly connected to the limiting plate 203 at one end close to the self-rotating hole 106. The longitudinal section of the bearing plate 201 is an arc shape. The limiting plate 203 is larger than the sliding hole 103. The limiting plate 203 is rotatably mounted with a support wheel 204 at one end close to the self-rotating hole 106. The sliding rod 202 is rotatably mounted with the contact ball 205 at one end away from the self-rotating hole 106. The contact ball 205 and the bearing plate 201 are in contact with each other.

The inner contact sheet 401, the inner contact block 402, the outer contact sheet 405, and the outer contact block 406 are used to increase the tightness of the connection between the rotating connection contact component 4 and the sliding sleeve 301 and the inner sheet 501.

[0050] refer to Fig.11 , Fig.12 The operating nut 504 is used for adjustment. The middle piece 503 and the outer piece 505 can facilitate the cooperation between the wrench tool and the operating nut 504. The middle piece 503 and the inner piece 501 are used to limit the cooperation between the chain and the sprocket 506. When the operating nut 504 is rotated with a wrench tool, a single roller can be corrected and adjusted. If multiple rollers need to be corrected and adjusted at the same time, the sprocket 506 parts of the multiple rollers can be connected to each other with a chain, so that multiple rollers can be corrected and adjusted at one time.
