Load monitoring instrument and system of adhesive tape conveyor

Abstract

The invention discloses a load monitoring instrument and system of an adhesive tape conveyor. The monitoring instrument comprises one or more laser distance measurement modules, a laser control treatment module and a rotating structure. When the laser distance measurement modules rotate along with the rotating structure, raw coal on the adhesive tape conveyor is scanned, load distribution in unitlength on the adhesive tape conveyor can be obtained, and the current operating speed of the adhesive tape conveyor is calculated; the laser control treatment module determines the adjustment speed according to the load distribution in the unit length and the current operating speed, so that the adhesive tape conveyor operates according to the adjustment speed to achieve the purpose that the difference value between the load of a conveyer belt and rated load is in the preset range. When the monitoring instrument and system are applied, the distribution situation of coal current load on the adhesive tape conveyor can be safely and accurately monitored, so that the tape speed of the adhesive tape conveyor can be automatically adjusted according to the coal current load distribution of the adhesive tape conveyor, rated load operation can be performed, the transporting efficiency can be improved, and safe production management level of coal mines and economic benefits of the coal mines canbe increased.

Description

technical field [0001] The invention relates to the technical field of belt conveyor, in particular to a belt conveyor load monitor and system. Background technique [0002] Raw coal transportation in modern mines mostly adopts belt conveyor system, and it is developing towards large-scale and automatic. The raw coal on each mining face in the mine is transported to the centralized belt conveyor or underground coal bunker through the belt conveyor, and then the raw coal is transported to the strong belt conveyor through the coal feeder under the coal bunker and then transported to the wellhead, or through the main shaft The skip transports the raw coal to the above-ground coal washing plant. The length of each belt conveyor that makes up the raw coal transportation system of the coal mine ranges from several hundred meters to more than one thousand meters. The drive of the conveyor needs to be driven by dual motors. The power of each motor is about 1250kW-1850kW. The total ...

AI Technical Summary

Problems solved by technology

The working current of the driving motor of the belt conveyor indirectly reflects the coal transport flow of the belt conveyor, but the mechanical state of the belt conveyor will affect the detection, resulting in errors, which will cause partial overload and press coal shutdown

[0006] Therefore, on the one hand, the above-mentioned existing methods have disadvantages such as large detection error and great influence by environmental protection policies.

On the other hand, since the length of each belt conveyor belt in the coal mine transportation system ranges from hundreds of meters to thousands of meters, the above-mentioned existing method can only detect the local raw coal load on the belt conveyor, and control the belt conveyor in real time according to the local raw coal load. If the machine runs at a constant speed, the transportation system will often be in a state of speed adjustment, resulting in unstable operation of the transportation system, affecting transportation efficiency, and thus affecting coal mine output
