Description of drawings
Fig. 1 is that structure master of the present utility model looks scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By shown in Figure 1, the utility model comprises winch, assembly pulley, steel rope and skip bucket, winch 1 places in the hoist house on ground 13, place the first pulley (claiming again the first head sheave) 6 is housed on the ground pulley bracket, the assembly pulley that the second pulley (claiming again the first head sheave) 5 consists of, installed around steel rope 4 on the wire rope pulley 3 of assembly pulley and winch, assembly pulley and winch are linked together, consist of lift structure, the lifting of staggering mutually is housed on the steel rope of assembly pulley bottom, can insert the first skip bucket (claim not only the first measure hopper) 7a and the second skip bucket (but also claiming the second measure hopper) 7b of pit shaft, be equipped with above the lower turning of steel rope in pit shaft 14 and the first skip bucket 7a and the second skip bucket 7b the first corresponding quantitative outlet steel plate 11a suitable for reading, second quantitatively exports steel plate 11b, first quantitatively exports steel plate 11a, second quantitatively exports steel plate 11b bottom is equipped with respectively the first corresponding airduct 12a, the second airduct 12b, be parallel to pit shaft along vertically being equipped with in the pit shaft, and stretch out the buntons 8 of upper wellbore, be provided with the decelerate position inductor 9 than the high 15m of former decelerate position in the pit shaft, buntons 300m place is provided with combined aural and visual alarm 10, and the controller 2 that links to each other with winch is housed in the hoist house.
In order to guarantee result of use, the position of described the first pulley 6 on frame (routine techniques does not provide among the figure) is higher than the wire rope pulley 3 that the second pulley 5, the second pulleys 5 are higher than winch, consists of the lift structure of inclination; Described steel rope 4 is annular, installs around on wire rope pulley 3, the first pulley 6, the second pulley 5, and the first skip bucket 7a and the second skip bucket 7b are contained in respectively the first pulley 6, the second pulley 5 bottoms of pit shaft top and stretch on the annular wire rope of pit shaft.
Service condition of the present utility model is, after winch starts, the running of drive steel rope, thereby the first skip bucket 7a on the drive steel rope and the second skip bucket 7b, in pit shaft, do alternately up-and-down movement, when each skip bucket oral area moves to corresponding quantitative outlet steel plate place, begin in skip bucket, to feed, and under the blowing of airduct, rapidly and efficiently, fill accurately material (coal), and by annular wire rope under the effect of winch, skip bucket is pulled out pit shaft, carry out discharging, meanwhile, another skip bucket gos deep into underground quantity outlet steel plate place, begins charging, the handling labor that circulates successively, thus coal is transported in the pit shaft of exploitation.
The utility model compared with prior art has following useful technique effect:
One, improves the running velocity curve of elevator system, the decelerate position of change elevator system, improve the operating efficiency of elevator system.
Guaranteeing under the prerequisite of security improvement, original buntons prolonged two joints, prolonging the buntons of main shaft, further prolonging at the uniform velocity segment distance of elevator system, after prolong the deceleration point position.By changing winch (gig) acceleration, deceleration position, prolong at the uniform velocity segment distance, reduce the segment distance of creeping, and change the acceleration point of gig, accelerate in advance.And then reach the single cycle of run that shortens whole elevator system.
By continuous improvement and optimization, the single cycle of run of winch (gig) constantly shortens, and the time of single cycle of run had original 181.2 seconds to reduce to 120 seconds.
Two, improve loading technique, install the auxiliary facilities such as airduct additional, increase work efficiency
With the original skip bucket rear unlatching feeder that puts in place, Deng measure hopper load finish after, again the coal of measure hopper is put into skip bucket, then promote, change into skip bucket and just open feeder in service of pit shaft, when skip bucket reaches quantitative outlet steel plate position, finish quantitative loading process.
The obstruction that occurs in the skip loading process for measure hopper in addition and unload clean phenomenon, under measure hopper outlet steel plate, install airduct additional, utilize the airduct of down-hole that it is dried, speed of loading and efficient have greatly been improved, for reducing the coal breakage phenomenon of measure hopper loading process, install buntons (backplate) additional on the coal dropping port both sides of measure hopper, and improve angle, reduce the coal breakage phenomenon at the bottom of the main shaft, alleviated the worker's of transport team clear coal pressure.
The loading time has been shortened in the improvement of these measures and technique, and the loading time of gig shortened to 30 seconds by about 44.6 seconds.Improved the raising efficiency of gig.And alleviated the clear coal pressure of transport team, reduced the coal output from auxiliary shaft.Reached the purpose that improves the production efficiency of elevator system.
Three, install acoustic-optic alarm additional
By in PLC, increasing by one section winch operation control program, be used for monitoring the speed of elevator system, send the sound and light alarm signal when unusual entrucking occurring.Namely in winch operation an electric current threshold value only is set 300 meters the time, when the winch running current goes beyond the scope, the coal that is prompting operation worker skip bucket does not unload totally, should take corresponding operation measure, Effective Raise the production efficiency of elevator system, effectively having alleviated the collision problem between promoting and producing, better ensured carrying out smoothly of producing, is the innovation on the main shaft elevator system of colliery.
