Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a lower turning device for belt conveyors. Background Art

[0002] Belt conveyor, also known as belt conveyor, is a kind of transportation machinery, which is widely used in coal, metallurgy, transportation, electricity, building materials, chemical industry, port and other industries. Its layout forms are divided into horizontal transportation, upward transportation, downward transportation and plane turning transportation.

[0003] The turning phenomenon of belt conveyors is relatively common, especially when encountering large turning angles. On the ground, there is a large turning space without being affected by the surrounding environment, and the turning radius of the belt conveyor can reach more than 1000m. However, in coal mine tunnels, due to limited space, the turning radius is also limited, and the turning problem of the belt conveyor needs to be considered.

[0004] There are two common solutions:

[0005] 1. Belt conveyors overlap each other;

[0006] Disadvantages of this solution: 1. It increases the unloading points and fault points, which require special personnel to guard, especially multiple turns and S-shaped turns. This solution is difficult; 2. It increases the cost. Each belt conveyor needs to be equipped with a series of components such as drive motors and tensioners, and the foundation of the belt conveyor needs to be laid;

[0007] 2. Use a forced turning device;

[0008] The disadvantages of this solution are: 1. The forced turning device is large in size and complex in structure. The forced turning itself is expensive and requires processing in the lane, so the initial investment cost is high. 2. The forced turning device will affect the service life of the belt. 3. The forced turning device has serious wear problems on the special-shaped rollers, and the operating cost is high. 4. An additional unloading point is added, which requires special personnel to guard.

[0009] Therefore, the traditional solution has high requirements for the construction site, which is bound to increase the on-site construction volume and maintenance and management costs to meet the installation and use requirements of the equipment; moreover, in traditional belt conveyors, the conveyor belts in the turning sections are not pressed or blocked, which can easily cause the conveyor belts to climb the rollers, affecting the normal transportation of materials by the conveyor belts.
