Plate-type rapid quantitative loading system and method

Abstract

The invention relates to a plate-type rapid quantitative loading system and method. The system includes a bunker; the feed end of a storage plate type quantitative conveyer is arranged below the bunker; the inlet of a skip charging chute is arranged at the discharging end of the conveyer; the outlet of the skip charging chute is opposite to the upper port of the skip; the power of the storage plate type quantitative conveyer is provided by a variable speed transmission device; the storage plate type quantitative conveyer is provided with a plurality of weighing sensors; the weighing sensors are electrically connected with a weighing device; and the weighing device and the variable speed drive device are electrically connected with a controller. The invention ably adopts the storage plate type quantitative conveyer instead of a traditional tall vertical quantitative bucket; a horizontal conveyer in the process of nearly horizontal transportation of coal also weighs the coal; before the arrival of the skip, the conveyer can operate at a slow speed to form a buffer. The devices integrates transportation, weighing and buffer into one, greatly simplifies the equipment quantity in the whole weighing transport system, and also reduces the maintenance cost for 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.
