A plate-type rapid quantitative loading system and method

Abstract

The invention relates to a plate-type rapid quantitative loading system and method, comprising: a coal bunker, the feeding end of a storage-type plate-type quantitative conveyor is arranged under the coal bunker, and the inlet of a skip charging chute is arranged at the discharge end of the conveyor. The outlet of the charging chute is facing the upper mouth of the skip. The power of the storage type quantitative conveyor is composed of a variable speed transmission device. The storage type quantitative conveyor is equipped with multiple weighing sensors. connection, the weighing device and the variable speed transmission are electrically connected to the controller. The present invention cleverly adopts the storage type plate quantitative conveyor to replace the traditional vertical and tall quantitative bucket. The horizontal conveyor also weighs the coal during the process of transporting coal close to the level. When the skip does not come, it can also use Running at a slow speed forms a buffering effect. One device integrates transportation, weighing and buffering, which greatly simplifies the amount of equipment in the entire weighing and transportation system, and further reduces the maintenance cost of the equipment.

Description

technical field [0001] The invention relates to a plate-type rapid quantitative loading system and method, which is a mechanical system and method, and a system and method for loading and transporting bulk materials in coal mines. 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. Existing dosing buckets are usually vertical cyl...

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.
