Abstract
The invention discloses a belt type storing and conveying machine and a method for storing and conveying gangue for an underground heading face. Upper carrier rollers and lower carrier rollers are arranged on a rack at intervals; rotary drums are arranged at the two ends of the rack; a pair of driving drums and tensioning drums are arranged below the rack; the driving drums are dragged by a driving device to rotate; vertical supports are fixedly connected to the two sides of the rack at intervals; material blocking plates are arranged on the vertical supports so as to enable groove-type spaces to be formed above the conveying belt; and the driving device is composed of a permanent magnet direct-current driving frequency conversion speed regulating motor and a frequency converter, wherein the motor is in rigid linkage with the driving rollers through elastic pin couplings. When the gangue is output from the heading face, the groove type spaces of the storing and conveying machine running at a low constant speed are filled with the gangue sent to the machine. When storage is full, the machine stops running and waits for being unloaded; when a tunnel conveying system is free in coal conveying, the stored gangue can be rapidly unloaded to the tunnel conveying system of, and therefore time conflict between outputting the gangue from the heading face and outputting coal of a working face is solved, and the tunneling efficiency is greatly improved.
Description
Technical field
The present invention relates to mine down-hole driving face transportation device and storage equipment, is a kind of for the centralized stores of boring head output gangue, the integration apparatus of collective conveyance.
Background technology
The raw coal of each coal-face output of current underground coal mine and the spoil of each driving face output, all will be transported to major and minor well by main haulage roadway.In transportation, spoil is mixed in raw coal transportation system sometimes, causes raw coal Coal Quality Decline, adds ground washing burden.
For this reason, cash can not be transported during the most good luck coal in colliery, during fortune cash, coal can not be transported, and preferential to transport coal; So driving face only just can go out cash when not transporting coal, the spoil so just causing a P. drechsleri can not transport driving surface, just can not continue the driving of next circulation; Driving does not catch up with, and next coal-face just prepares not out; Therefore, the allotment problem of coal-face and driving face transport, becomes the bottleneck factor of the raw coal lifting of restriction mine and mine working face normal continuance.
The technology relevant with the application is common ribbon conveyer, the essential structure of belt conveyer is furnished with upper supporting roller and snub pulley at interval of certain distance in frame, the two ends of frame are provided with revolving cylinder, the below of frame is provided with a pair head roll and tensioner cylinder, and head roll drags running by actuating device; Actuating device is made up of three phase alternating current motor and motor operation control device.Because the upper band of load-transfer device is a plane or very shallow concave surface when transporting, spoil in delivery can not be piled up too thick, otherwise a large amount of spoil is scattered from head or is in operation from load-transfer device and drops, so current ribbon conveyer can not store a large amount of spoils.
Summary of the invention
The object of the invention is the drivage efficiency in order to improve driving face, overcome the restriction of coal work in the face of driving face transport systems, ensure mine working face normal continuance, common ribbon conveyer is improved, designs a kind of can to transport and can the belt accumulating conveyor for driving face of temporary reservoir; This belt accumulating conveyor is arranged in digging laneway.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of driving face belt accumulating conveyor, it is furnished with upper supporting roller and snub pulley at interval of certain distance in frame, and carrying roller is furnished with load-transfer device, and the two ends of frame are provided with revolving cylinder, the below of frame is provided with a pair head roll and tensioner cylinder, and head roll drags running by actuating device; It is characterized in that: be fixedly connected with perpendicular support in the both sides of frame at interval of certain distance, installed the striker plate of 6mm plate iron processing by perpendicular support, make more than load-transfer device form slot type space, and ensure the section payload space 0.8-1.0 sq m in slot type space;
Described actuating device drives frequency-conversion and speed-regulation motor and frequency converter to form by DC; DC drive frequency-conversion and speed-regulation motor by elastic dowel pin shaft coupling together with head roll rigid attachment.
Above-mentioned belt accumulating conveyor is utilized in the method for driving face accumulating spoil to be: when going out cash when boring head, pass through variable frequency control, load-transfer device with 0.2m/s speed low speed, travel at the uniform speed, spoil long-pending tankful formula space in low cruise that driving face is sent here, when whole piece load-transfer device stores full, out of service etc. to be unloaded; When the transport systems fortune coal in Dai great lane is idle, adjustment frequency converter makes load-transfer device switch to the running velocity of 0.5m/s, and fast discharging is on the transport systems in large lane.Accumulating conveyor 50 meters of length computation, can store 40-50 cubic meter as taped, and what be enough to meet 2-3 P. drechsleri goes out cash amount.
The good effect of the application is:
1, by the supporting application of belt accumulating conveyor at boring head, achieve the pick of underground coal mine boring head, prop up, store up, transport integration, the spoil amount of 2-3 normal cyclic can be stored at every turn, solve the time inconsistency that boring head discharge refuse stone and driving surface arrange coal, drivage efficiency is improved greatly.
2, this device achieves that the time of concentration of coal, cash timesharing partite transport and transport systems is run, going out the cash time shortens to 10min by original 2h, the long-time underloading of transport systems or no-load run are stopped, simultaneously can according to peak and valley time Reasonable adjustment time of run, discharge refuse is concentrated in Yun Meigu section, improve system transfer efficiency, greatly reduce electric cost expenditure, realize economize expense and reduce expend.
3, due to spoil collective conveyance, avoid spoil and be mixed in raw coal transportation system, improve raw coal ature of coal, alleviate ground washing burden.
4, adopt Modular Structure Design, whole component is fixed connection by bolt, and structure is simple, lightweight, facilitates underground transportation and in-site installation, and design length can arbitrarily need to adjust according to scene from 30-50m.
