Deviation rectifying device of coal mine belt conveyor

Abstract

The invention relates to the technical field of mine shaft equipment, and provides a deviation rectifying device of a coal mine belt conveyor. The deviation rectifying device comprises a deviation rectifying rack which is crossed and is fixedly arranged on a rack, wherein upper deviation rectifying rollers are symmetrically arranged at the two sides of the upper part of the deviation rectifying rack; lower deviation rectifying rollers are symmetrically arranged at the two sides of the lower part of the deviation rectifying rack; and each upper deviation rectifying roller and each lower deviation rectifying roller are rotatably arranged on one deviation rectifying roller base separately, and a roller base regulating assembly is arranged on the deviation rectifying rack. The deviation rectifying device of the coal mine belt conveyor provided by the invention can effectively perform deviation rectifying on a conveyor belt on a machine head and a machine tail, can regulate deviation rectifying amount according to a practical condition, eliminates coal falling-scattering and stacking phenomena, relieves labor intensity of an operator, and guarantees safe operation of the coal mine beltconveyor.

Description

technical field [0001] The invention relates to the technical field of mine equipment, in particular to a deviation correcting device for a coal mine belt conveyor. Background technique [0002] As we all know, there are many reasons for the deviation of the belt conveyor, such as: the falling point of the material is not in the middle of the belt section, the installation of the head, tail, reversing roller, intermediate frame, etc. is not correct, the belt street is not perpendicular to the belt center line, and the belt inside Factors such as uneven tension, inflexible operation of idler rollers, inconsistent wear of the rollers, and materials between the rollers and the belt can all cause the belt to deviate. If the belt runs lightly, the material will spill and the belt will be edged, and if it is serious, it will cause tearing of the belt and emergency stop accidents. [0003] The coal in the mine is transported by belt conveyors, and the production environment in the...

Problems solved by technology

[0002] As we all know, there are many reasons for the deviation of the belt conveyor, such as: the falling point of the material is not in the middle of the belt section, the installation of the head, tail, reversing roller, intermediate frame, etc. is not correct, the belt street is not perpendicular to the belt center line, and the belt inside Uneven tension, inflexible idler rollers, inconsistent roller wear, and material between the roller and the belt can cause the belt to deviate

If the belt runs lightly, the material will spill and the belt will be edged; if it is serious, it will cause belt tearing and emergency stop accidents

[0003] Belt conveyors are used to transport coal in the mine, and the production environment in the underground mining area of ​​the No. 2 Coal Mine is relatively harsh, with uneven ground and long transport distances

At the same time, the removal and installation of belts is relatively frequent, and considering economic reasons, the old belts that have been removed are often reused many times, and the edges of the old belts are severely worn, which can easily cause the problem of belt deviation during transportation

[0004] Due to the special production environment in the mine, most of the existing belt deviation correction devices are installed in the middle transportation part, and the structure of the belt deviation correction device installed in the middle transportation part is relatively simple, which is not suitable for the deviation correction of the belt at the nose and tail of the conveyor. It is impossible to install and use the belt conveyor within the full haul distance, resulting in deviations at the nose and tail of the belt conveyor

However, the deviation of the belts at the nose and tail can easily cause coal spillage and coal piles.
