Description

Coal mine conveying support roller for coal preparation plant

Technical Field

The utility model discloses a coal mine conveying support roller for a coal preparation plant, relates to a support roller used in the coal preparation plant and used for conveying a coal mine, and belongs to the technical field of coal mine conveying. In particular to a supporting roller for carrying out buffering and shock absorption on a conveying belt through a buffering structure.

Background

Coal transportation in coal preparation plants is generally completed by using a belt conveyor, and in order to improve the stability of a belt during the operation of the belt conveyor, a series of carrier rollers are generally arranged below the belt for supporting so as to prevent the belt from inclining or even falling off, because the sizes and the shapes of the mined coals are different, the coal is placed on the belt by using a machine, the rolling and sliding of the coal have certain randomness, so that the coal is easy to be unevenly distributed on the belt, when a certain amount of coal is placed on the belt conveyor, the belt can incline to a certain degree due to the gravity of the coal and the unbalanced distribution of the coal on the belt, and the conveyer can produce certain vibrations when moving, and current bearing roller does not set up buffering shock-absorbing structure, can't alleviate the vibrations between bearing roller and the belt for coal rolls easily from the belt and falls to pile up, increases the later stage clearance degree of difficulty.

Publication number CN209758238U discloses a bearing roller, including barrel, roller, bearing frame and bearing, the tip of barrel is equipped with step portion, the bearing frame include with the outer wall fixed connection's of step portion connecting cylinder, the outer wall of connecting cylinder with the outer wall parallel and level of barrel, this bearing roller only through changing the barrel material, make the bearing roller barrel more wear-resisting, but do not set up buffering shock-absorbing structure, when the conveyer produced vibrations, coal rolled off easily from the belt and piles up, increase the later stage clearance degree of difficulty.

Disclosure of Invention

In order to improve the situation, the utility model provides the support roller for the coal mine transmission of the coal preparation plant, which is used for carrying out buffering and shock absorption on the conveying belt through the buffering structure, so that the shock between the support roller and the belt can be reduced, and the coal conveyed on the belt is not easy to fall off.

The utility model relates to a coal mine transmission supporting roller for a coal preparation plant, which is realized by the following steps: the utility model relates to a coal mine transmission support carrier roller for a coal preparation plant, which consists of a main roller shaft, a damping boss, telescopic rods, limiting rings, a central shaft and a spring, wherein the main roller shaft is sleeved on the central shaft, the damping boss is sleeved at two ends of the central shaft respectively, the bottom of the damping boss is provided with an annular groove, a plurality of groups of telescopic rods are arranged in the annular groove at equal intervals along the circumferential direction, at least one group of telescopic rods is arranged, two ends of the plurality of groups of telescopic rods are connected with the upper inner wall and the lower inner wall of the annular groove respectively, the spring is sleeved on the telescopic rods, two ends of the spring are connected with the upper inner wall and the lower inner wall of the annular groove respectively, the damping boss is made of an elastic material, the limiting rings are sleeved at two ends of the central shaft respectively, and the limiting rings are positioned outside the damping boss;

it should be noted that, the terms "upper", "lower", "left" and "right" in the present invention are based on the terms "upper", "lower", "left" and "right" in fig. 3.

Advantageous effects

Firstly, the vibration between the carrier roller and the belt can be reduced, so that the coal transported on the belt is not easy to fall off.

Secondly, the structure is simple, convenient and practical.

Thirdly, the cost is low, and the popularization is convenient.

In the attached drawings

Wherein the method comprises the following steps: the damping device comprises a main roller shaft 1, a damping boss 2, a telescopic rod 3, a limiting ring 4, a central shaft 5 and a spring 6.

The specific implementation mode is as follows:

the utility model relates to a coal mine transmission supporting roller for a coal preparation plant, which is realized by the following steps: the utility model relates to a coal mine transmission support carrier roller for a coal preparation plant, which consists of a main roller shaft 1, a damping boss 2, telescopic rods 3, limiting rings 4, a central shaft 5 and springs 6, wherein the main roller shaft 1 is sleeved on the central shaft 5, the damping boss 2 is sleeved at two ends of the central shaft 5 respectively, annular grooves are formed in the bottom of the damping boss 2, a plurality of groups of telescopic rods 3 are arranged in the annular grooves at equal intervals along the circumferential direction, at least one group of telescopic rods 3 is arranged, two ends of the plurality of groups of telescopic rods 3 are connected with the upper inner wall and the lower inner wall of the annular groove respectively, the springs 6 are sleeved on the telescopic rods 3, two ends of the springs 6 are connected with the upper inner wall and the lower inner wall of the annular grooves respectively, the damping boss 2 is made of an elastic material, the limiting rings 4 are sleeved at two ends of the central shaft 5 respectively, and the limiting rings 4 are positioned outside the damping boss 2;

it should be noted that, the terms "upper", "lower", "left" and "right" in the present invention are based on the terms "upper", "lower", "left" and "right" in fig. 3;

during the use, at first install this bearing roller in the conveyer frame through center pin 5, when needs fortune coal, start the conveyer, the belt that is equipped with coal rotates, and the belt pushes down shock attenuation boss 2, and telescopic link 3 is flexible, and spring 6 compresses, supports the belt, and the elastic restoring force of spring 6 can cushion the vibrations that produce during the conveyer operation simultaneously to alleviate the vibrations between bearing roller and the belt.

The spring 6 and the telescopic rod 3 are matched with the damping boss 2, so that the belt can be buffered and damped;
