Weighing method and device of rapid quantitative plate conveyer

Abstract

The invention relates to a weighing method and device of a rapid quantitative plate conveyer. The device comprises a chain wheel and a chain of the plate conveyer. A short shaft with the rotating axis perpendicular to the movement direction of the chain is arranged on each chain section of the chain. A wheel is arranged on each short shaft. The wheels on the two sides of the chain run on one or more guide rails on the left side and the right side of the chain respectively. The guide rails on the left side and the right side are installed on weighing platforms respectively, wherein the number of the guide rails is equal to the number of the weighing platforms. A plurality of weighing sensors are arranged below each weighing platform. Through the guide rails, the weights, dispersed on all bearing plates, of bulb materials are concentrated on the guide rails, the weights on the guide rails are then concentrated on the weighing platforms, the weights flat spread and accumulated on the bearing plates of the conveyer are concentrated under the common effect of the wheels, the guide rails and weighing racks so that the bulk materials can be weighed in the movement. According to the method and device, the weighing function and the conveying function of the plate conveyer are achieved, and the method and device play a very key role in reducing the height of a chamber and reducing the cost.

Description

technical field [0001] The invention relates to a weighing method and device of a plate-type rapid quantitative conveyor, which is a mechanical measuring method and device, and a method and device for measuring materials in coal mines for loading and transporting bulk materials. Background technique [0002] Modern deep coal mining uses vertical transport skips that move up and down at high speed to transport the coal excavated hundreds of meters deep to the ground. Since the skip needs to transport tens of tons of materials to move upward each time, its traction steel rope is subject to great tension. Therefore, the loading capacity of the skip must be strictly limited each time to absolutely prevent overloading, otherwise serious accidents may occur. For this reason, in the existing mine, the quantitative bucket of loading capacity weighing is specially arranged, in order to weigh the bulk material of appropriate weight before loading skip, prevents from being overloaded. ...

Problems solved by technology

Even so, in some formations with relatively soft surrounding rocks, the foundation of the tall loading chamber where the quantitative bucket and its corresponding equipment are excavated at the edge of the wellbore destroys the continuity of the wellbore and reduces the bearing capacity of the well wall. The weight of itself and the loaded coal also cause great pressure on the surrounding rock of the shaft. In order to ensure safety, it is necessary to strengthen the engineering treatment of the shaft around the chamber, which increases the difficulty of construction and increases the cost of construction and maintenance.
