Description

Technical Field

[0001] The utility model belongs to the technical field of mining machinery, and particularly relates to an auxiliary device for replacing a belt of an uphill belt conveyor. Background Art

[0002] The uphill belt conveyor is a special application of the belt conveyor, primarily used for transporting materials in uphill scenarios. In existing technologies, the belt changing process for uphill belt conveyors relies primarily on manual operation, with the aid of tools such as winches and cranes. Because the new belt stacking point is 10 meters away from the point where the new belt enters the uphill belt conveyor, the new belt is prone to deviation during unrolling, resulting in the new and old belts not being able to overlap and secure. This, in turn, causes the new belt to rub against the ground before entering the uphill belt conveyor, increasing the difficulty of pulling the belt and even damaging the new belt. Furthermore, because the uphill belt conveyor is at a certain angle to the horizontal plane, the new belt may not be able to fully fit the old belt of the uphill belt conveyor during unrolling, resulting in low operating efficiency and increased labor intensity for operators. Utility Model Content

[0003] The purpose of the utility model is to provide an auxiliary device for replacing the belt of an uphill belt conveyor, so as to solve the problems of lack of auxiliary equipment, low operating efficiency, easy deviation of the belt, difficulty in pulling the belt due to friction between the new belt and the ground, and the inability of the new belt to completely fit the old belt of the uphill belt conveyor when replacing the belt of the uphill belt conveyor.

[0004] The utility model adopts the following technical solution: an auxiliary device for replacing the belt of an uphill belt conveyor, comprising:

[0005] The support frame is located in the middle of the uphill belt conveyor and at the foot of the waste rock mountain. The uphill belt conveyor is used to transport the waste rock upward from the underground mine, and then climb out of the tunnel on the ground and transport it to the top of the waste rock mountain, and discharge the waste rock.

[0006] The first rollers are horizontally mounted on the side of the support frame close to the well bottom, and multiple groups are arranged in parallel along the direction of the support frame. They are used to support the new belt of the uphill belt conveyor and enable the new belt to be unrolled on them and away from the ground to avoid friction with the ground;

[0007] The third roller is horizontally installed on the side of the support frame close to the waste rock pile;

[0008] The second roller is horizontally installed on the support frame and is located below the third roller; a receiving area is formed between the third roller and the second roller, and the receiving area is used for the new belt from the upper side of the first roller to pass through and be transported to the upper side of the old belt; so that the new belt and the old belt are fixed together and transported upward under the power of the uphill belt conveyor to complete the belt change.

[0009] Furthermore, a plurality of first rollers are provided, and the distance between two adjacent first rollers is 1 to 3 meters.

[0010] Furthermore, the support frame consists of a left fixed rod and a right fixed rod parallel to each other, and the left fixed rod and the right fixed rod are both fixed on the ground at the foot of the mountain near the slag heap. The angle between the direction of the left fixed rod and the right fixed rod and the direction of the belt of the uphill belt conveyor is 140°~155°.

[0011] Furthermore, it also includes:

[0012] The fourth roller and the fifth roller are respectively installed on the left fixed rod and the right fixed rod. The installation direction of the fourth roller and the fifth roller is perpendicular to the installation direction of the second roller. The fourth roller and the fifth roller are arranged opposite to each other and are located between the first roller and the second roller.

[0013] The beneficial effects of the utility model are:

[0014] The utility model is placed at the foot of the waste rock mountain, and when replacing the new belt, the new belt can be lifted up and smoothly enter the uphill belt conveyor, thereby improving the belt replacement efficiency and reducing the work intensity of the workers; it can avoid the new belt from rubbing directly on the ground before entering the uphill belt conveyor, thereby reducing the difficulty of pulling the belt; by passing the new belt through the accommodation area between the second roller and the third roller, the angle of the new belt before entering the uphill belt conveyor can be adjusted, thereby avoiding the new belt from not being able to fit with the old belt during the belt unwinding process;

[0015] The utility model can avoid the deviation problem of the new belt during the belt extension process by arranging the fourth roller and the fifth roller which are installed perpendicular to the second roller, which is conducive to overlapping and fixing the new belt and the old belt, thereby facilitating belt replacement.
