Description

Technical Field

[0001] This utility model belongs to the technical field of belt alignment devices, specifically relating to a belt conveyor belt alignment device. Background Technology

[0002] Belt conveyors are continuous conveying devices that use flexible conveyor belts as both material-bearing and traction components. They offer advantages such as high conveying capacity, low power consumption, simple structure, and strong adaptability to materials, and are widely used in industries such as coal, building materials, metallurgy, ports, and power. During material transport, belts are prone to belt misalignment. Mild misalignment can cause material spillage and belt wear, while severe misalignment can lead to intense friction between the belt and the frame, causing the belt to soften, burn, or even ignite, triggering other serious accidents (such as coal mine gas or coal dust explosions). Since the conveyor belt accounts for 30% to 50% of the total cost of the conveyor, belt misalignment not only affects production and shortens the belt's lifespan but also causes significant economic losses and poses a serious threat to the lives of workers along the conveyor line. During the initial operation of a belt conveyor, misalignment is very noticeable and can be adjusted manually. However, during normal operation, the misalignment is less pronounced, and manual adjustment is time-consuming, labor-intensive, and ineffective. Summary of the Invention

[0003] This utility model provides a belt conveyor correction device to solve the problems mentioned in the background art. The specific solution is as follows:

[0004] A belt conveyor correction device includes a lower crossbeam and a trough-shaped mounting frame disposed above the lower crossbeam. The trough-shaped mounting frame contains a set of trough-shaped idlers. Fixed angle irons that can be connected to the belt conveyor frame are respectively connected to both ends of the lower crossbeam. A bearing seat is vertically disposed at the center of the lower crossbeam. Bearings are respectively disposed on the upper and lower sides of the bearing seat. A central shaft is vertically disposed at the center of the lower end face of the trough-shaped mounting frame. The central shaft passes through the two bearings and is fixed to the lower bearing by nuts. A limiting rod that can extend into the trough-shaped mounting frame is vertically disposed on the lower crossbeam on one side of the bearing seat. Two correction idlers perpendicular to the trough-shaped mounting frame are symmetrically disposed on both sides of the trough-shaped mounting frame.

[0005] Furthermore, a cover plate is detachably connected to the lower end of the bearing housing via bolts.

[0006] Furthermore, each end of the lower crossbeam is provided with a mounting plate that is vertically upward, and both mounting plates are provided with a correction auxiliary mechanism.

[0007] Furthermore, the correction auxiliary mechanism includes two support plates spaced apart on the upper part of the mounting plate. The two support plates are respectively inclined downwards. Pressure rollers that can roll along the conveyor belt direction are respectively provided on the side walls of the opposite sides of the two support plates. A stop roller that can roll along the conveyor belt direction is provided on the mounting plate between the two pressure rollers.

[0008] Furthermore, both sides of the trough-shaped idler group are tapered idlers, and the large ends of the two tapered idlers are located at one end of the idler in the middle of the trough-shaped idler group.

[0009] The beneficial effects of this utility model are:

[0010] This utility model discloses a belt conveyor correction device. It utilizes a central shaft mounted on the lower end face of a trough-shaped mounting frame, a matching bearing seat and bearing, a limiting rod, and two correction rollers. When the conveyor belt deviates from its designated path, the entire trough-shaped mounting frame shifts towards the side of the belt deviation. The uneven friction of the conveyor belt running on the shifted trough-shaped rollers, combined with the correction rollers on both sides, corrects the belt's deviation. Furthermore, a correction auxiliary mechanism, with the conveyor belt blocked by pressure rollers and with guide rollers abutting against the side of the conveyor belt, forces the belt to gradually return to its original position. The entire correction process requires no manual inspection or adjustment, saving time and labor. It avoids wear and tear on the conveyor belt, preventing increased transportation costs and significantly reducing labor costs while ensuring worker safety. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] See Figure 1-5 A belt conveyor correction device includes a lower crossbeam 1 and a trough-shaped mounting frame 2 disposed above the lower crossbeam 1. The trough-shaped mounting frame 2 is prior art in this field. The trough-shaped mounting frame 2 has its trough opening facing upwards. A trough-shaped idler roller group 3 is disposed inside the trough-shaped mounting frame 2. Fixed angle irons that can be connected to the belt conveyor frame are respectively connected to both ends of the lower crossbeam 1. A bearing seat 4 is vertically disposed at the center of the lower crossbeam 1. A through hole is vertically opened at the center of the lower crossbeam 1. The lower part of the bearing seat 4 passes through the through hole and is detachably connected to the lower crossbeam 1 by bolts. Bearings 5 ​​are respectively disposed on the upper and lower sides inside the bearing seat 4. The bearing seat 4 has a step inside, and two bearings 5 ​​are respectively set on the upper and lower sides of the step. The center shaft 6 is vertically downward at the center of the lower end face of the grooved mounting frame 2. The center shaft 6 passes through the two bearings 5 ​​and is fixed to the lower bearing 5 with nuts, so that the grooved mounting frame 2 can rotate along the lower crossbeam 1. A limiting rod 7 that can extend into the grooved mounting frame 2 is vertically set on the lower crossbeam 1 on one side of the bearing seat 4. The limiting rod 7 is locked to the lower crossbeam 1 with nuts. The setting of the limiting rod 7 is convenient to limit the offset angle of the grooved mounting frame 2. Two correction rollers 8 perpendicular to it are symmetrically set on both sides of the grooved mounting frame 2.

[0019] The preferred bearing housing 4 has a cover plate 9 that is detachably connected to its lower end by bolts.

[0020] The preferred lower crossbeam 1 has mounting plates 10 vertically upward at both ends, and each mounting plate 10 is equipped with a correction auxiliary mechanism 11.

[0021] The preferred correction auxiliary mechanism 11 includes two support plates 12 spaced apart on the upper part of the mounting plate 10. The two support plates 12 are inclined downwards, and the inclination angle matches the inclination angle of the conveyor belt edge. The side walls of the two support plates 12 on opposite sides are respectively provided with pressure rollers 13 that can roll along the conveyor belt direction. The mounting plate 10 between the two pressure rollers 13 is provided with a stop roller 14 that can roll along the conveyor belt direction. The pressure rollers 13 are located on one side of the trough-shaped mounting frame 2 and are positioned between the two pressure rollers 13 when the conveyor belt is transported. The edge side of the conveyor belt and the stop roller 14 are separated by a gap.

[0022] The preferred trough-shaped idler group 3 has two conical idler rollers 301 on both sides, and the large ends of the two conical idler rollers 301 are respectively located at one end of the idler roller in the middle of the trough-shaped idler group.

[0023] The working principle of this utility model is as follows: First, when the conveyor belt is installed, its two sides are located between the two pressure rollers 13 on both sides, and its two side edges are close to the two guide rollers 14. When the conveyor belt deviates during the conveying process, due to the bearing seats 4 and bearings 5, the entire trough mounting frame 2 will shift to the side of the conveyor belt that deviates. At this time, the uneven friction of the conveyor belt running on the deviated trough idler group 3, combined with the correction rollers 8 on both sides, will block it. At the same time, the two sets of guide rollers 14 located on the edge side of the conveyor belt will block it, thereby achieving the purpose of correction.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
