Novel underground multi-belt speed matching flexible control device

Abstract

The invention discloses a novel underground multi-belt speed matching flexible control device. The device is characterized by comprising an underground conveying belt system, belt speed sensors, an electronic belt scale and a control system. According to the device, matching of the conveying capacity and speed of the belt coal conveying system is realized, then the effective operation time of thebelt conveying system can be obviously prolonged, the production efficiency can be improved, the belt overload and coal piling accidents are reduced or even avoided, meanwhile, the maintenance time ofbelt equipment can be greatly shortened, and the service life of belt conveying equipment is prolonged; the operation cost of the equipment is reduced, and the production safety is improved; the economic and social benefits are very obvious; and in addition, for the multi-belt speed and conveying capacity matching system, the speed and the coal conveying amount of each underground coal conveyingbelt and the equipment load can be monitored in real time, so that the coal production process can be monitored and managed, the intelligent control over the belt coal conveying system is realized, and the requirements of modern mine safety production scheduling are met and adapted.

Description

technical field [0001] The invention relates to the technical field of coal, and in particular provides a novel downhole multi-belt speed matching flexible control device. Background technique [0002] The belt conveyor system for underground coal is one of the main working systems in coal mine production, and plays an important role in coal mine safety production. At present, the speed control mode of the panels and main lane belts in some underground mining areas still adopts the traditional independent operation mode, and the production of the panels is slowed down and reduced by artificially observing the coal transport volume of the main lane belt and each panel belt. The belt conveying speed of the panel can be adjusted, but because of the inertia and lag of the conveying system, coupled with the factors of human observation, it is impossible to guarantee the balanced and stable belt conveying. However, if the belt conveying system is blocked, buried or overloaded, it...

Problems solved by technology

At present, the speed control mode of the panels and main lane belts in some underground mining areas still adopts the traditional independent operation mode, and the production of the panels is slowed down and reduced by artificially observing the coal transport volume of the main lane belt and each panel belt. The belt conveying speed of the panel can be adjusted, but because of the inertia and lag of the conveying system, coupled with the factors of human observation, it is impossible to guarantee the balanced and stable belt conveying

However, if the belt conveying system is blocked, buried or overloaded, it will cause the underground belt conveying system to fail to operate normally, or even cause damage to the belt conveying system, so that the coal produced in the underground cannot be transported to the mine normally, resulting in the suspension of coal mine production and increasing the labor costs of workers. Labor intensity, even poses a huge threat to production and staff

Especially for coal mining in multiple panels at the same time, it is transported to the main road belt at the same time, because the randomness of coal mining production is more likely to cause unbalanced coal transportation by the main road belt, causing instantaneous overload of the main road belt, which will cause damage to the belt And the damage of the belt drive equipment; more seriously, it will cause coal piles or even burial at the junction of the trough belt and the main belt

However, the belt is buried, cleaned up and restored to production, which requires a lot of manpower, material resources and time costs.
