The end faces of the upper and lower rollers are fitted with buckles to prevent coal particles and shower water from entering.

Description

Anti-deviation grooved idler roller in the belt storage part of the belt conveyor

technical field

The utility model relates to an accessory part of a belt conveyor in a coal mine, in particular to an anti-deviation groove-shaped support roller of a belt storage part of the belt conveyor.

Background technique

The belt conveyor is the main electromechanical equipment used to transport raw coal out of the mine working face. The quality of its use directly restricts the annual output of a mine and the input of production costs. Through in-depth understanding of the underground team, the belt was scrapped before it reached the service life. The main reason was that the belt was unduely worn, folded, and pulled due to deviation during use, especially for belt conveyors. It is more difficult to deal with the deviation of the head storage belt belt after going back and forth through multiple layers. The deviation phenomenon of multi-layer belts in the belt storage part of the belt conveyor is more complicated. Due to the action of each reversing roller, the running direction of the adjacent two layers of belts is opposite, and the deviation direction and deviation amount are different. . In order to correct the deviation, the usual practice of the team is to vertically install a set of lower rollers on both sides of the belt, and the lower rollers are fixed on the large frame. Due to the limitation of the installation space, the installation position of the lower rollers on the left and right sides is about The center line of the machine is not symmetrical. When two or more layers of belts deviate to the same side as a whole, the bottom idler installed to prevent deviation will not turn. After a long period of operation, the belt will be folded, pulled, and severely worn. Greatly reduced service life.

Contents of the invention

The purpose of the utility model is to solve the problem of deviation of the multi-layer belts in the belt storage part of the belt conveyor, and provide a deviation-proof idler roller.

The utility model is realized by adopting the following technical solutions:

An anti-deviation trough-shaped idler roller in the belt storage part of a belt conveyor, comprising a long axis on which idler rollers with different lengths are arranged, and the outer shape of the idler rollers is that the diameter at both ends is large and the diameter in the middle is small Groove shape; each roller is installed on the long axis through bearings; the two ends of the long axis are respectively provided with grooves, and the two grooves are respectively equipped with elastic springs for positioning the first and last two rollers on the long axis. The inner ring of the adjacent bearing is positioned by the shaft sleeve, and the outer ring of the bearing is positioned by the groove structure of the respective idler; the adjacent end faces of the two idlers are matched in the form of buckle.

When in use, the upper and lower ends of the long axis of the anti-deviation roller are respectively inserted into the slots of the belt frame and the fixed frame, and then fastened to the head frame with bolts. An anti-running idler roller is installed on each side. The length of the roller on the long axis is designed according to the different distance between the belt layers of the storage belt. The outer shape of the roller is a trough with a large diameter at both ends and a small diameter in the middle. Keep a certain distance between the belt and the roller when it does not deviate, and it can ensure that the anti-deviation rollers installed on both sides of the large frame are symmetrical about the center line of the belt. Bearings with dust covers are installed inside the rollers, and the bearings between the rollers are positioned with bushings, so as to ensure that the rollers do not interfere with each other when they turn differently. The end faces between the upper and lower rollers are matched in the form of buckles to prevent coal particles and shower water from entering.

The utility model has a reasonable design, effectively solves the problem that the multi-layer belts of the belt storage part of the belt conveyor deviate, and prolongs the service life of the belts.

Detailed ways

Specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

An anti-deviation trough-shaped idler roller in the belt storage part of a belt conveyor, as shown in FIG. The external shape is a trough with large diameter at both ends and small diameter in the middle; the length of the rollers is designed according to the different belt layer spacing in the belt storage part, for example, the belt in the belt storage part of the belt conveyor in Figure 2 is divided into 5 layers from top to bottom, According to the layer spacing of the belt, the length of the top-to-bottom rollers on the long axis is 120mm, 100mm, 170mm, 280mm and 200mm, the first roller is 90mm away from the shaft end, and the fifth roller is 50mm away from the shaft end ;The outer shape of the idler roller is a groove shape with large diameter at both ends and small diameter in the middle. This groove structure can not only ensure a certain distance between the belt and the roller when it does not deviate, but also ensure that the The anti-deviation roller is symmetrical about the center of the belt.

As shown in Figure 2, a groove is opened at both ends of the major axis 1, and an elastic expansion ring 4 is installed in the groove to position the first and last two rollers on the major axis 1. Each roller 2 is installed on the long axis 1 through the bearing 3. The roller bearing 3 adopts a bearing with a dust cover. The outer ring of the bearing is positioned by the groove structure of the respective roller, and the inner ring is positioned by the sleeve 5, so as to ensure that each roller The steering does not interfere with each other at the same time. The end faces between the upper and lower rollers are matched in the form of buckles to prevent coal particles and shower water from entering.

During use, the upper and lower ends of the long axis of the anti-deviation roller are inserted into the draw-in grooves of the belt frame 7 and the fixed mount 8 respectively, and then are fastened on the head frame with bolts. An anti-deviation grooved roller is installed on both sides to ensure that the anti-deviation rollers installed on both sides of the large frame are symmetrical about the center line of the belt 6. It solves the problem of deviation of multi-layer belts in the belt storage part of the belt conveyor, and prolongs the service life of the belts.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model without limitation. Although detailed descriptions have been made with reference to the embodiments of the utility model, those of ordinary skill in the art should understand that the technology of the utility model The modification or equivalent replacement of the scheme does not depart from the spirit and scope of the technical scheme of the present utility model, and all of them shall be covered by the protection scope of the claims of the present utility model.
