Abstract
The utility model discloses a self-powered up-open type fan-shaped gate skip for lifting a mine vertical shaft skip, the skip comprises a framework and a skip box, wherein, the skip box is fixed in the framework, a fan-shaped gate is arranged at a coal discharge port positioned on the side surface of the lower part of the skip box through a rotary shaft, the fan-shaped gate comprises two fan-shaped side plates, the front ends of the two fan-shaped side plates are connected with a circular arc-shaped plate, the back ends of the fan-shaped side plates are connected with an unloading shaft, an air cylinder is connected between the unloading shaft of the fan-shaped gate and the framework, one end of a pipeline is connected with an air inlet and outlet of the air cylinder, and the other end isfixed at the upper part of an upper plate of the framework. The gate skip has the advantages of self-powered property, simple structure, good self-locking performance, safety, reliability, rapid and smooth unloading, no coal sprinkling phenomenon, without need of increasing the height of a shaft frame, and has no impacts on the shaft frame during unloading.
Description
Technical field
The utility model relates to a kind of skip bucket that is used for mine vertical shaft skip hoisting.
Background technology
In vertical shaft skip promoted, the skip bucket of mine use at present mainly contained outer power unloading skip bucket and bend unloads skip bucket automatically.
Outer power unloading skip bucket mainly contains three kinds of forms, and a kind of is vertical floodgate, and a kind of is end sector gate, and a kind of is the side sector gate.The patent No. is that 93244277.3 disclosed outer power side hopper-bottom vertical shaft skip buckets are a kind of outer power side sector gate skip buckets.All need utilize the discharging gear of being located on the derrick during their unloadings.Its advantage is: need not increase hoisting depth, derrick is not almost impacted, lifting can be adopted three stage velocity diagrams, can shorten hoisting cycle.Its shortcoming is: unloading time is long, and it is bigger that the vertical floodgate skip bucket spreads the coal amount.
Bend unloads skip bucket automatically and mainly contains two kinds of forms, and a kind of is bottom-open type, and a kind of is to go up open type.The patent No. is that the 200320120250.6 disclosed large-scale open type side fan-shaped gate curve trail load skip buckets of going up are to go up open type sector gate curve trail load skip bucket.All need utilize the fixedly bend of being located on the derrick during their unloadings.Its advantage is: simple in structure, and unloading quick and stable, last open type skip bucket safe reliability height.Its shortcoming is: bend is installed on derrick, during unloading derrick is produced impact, cause the height of headframe to increase.
In sum, outer power unloads skip bucket, all needs install discharging gear when bend unloads dustpan unloading automatically on derrick, outer power unloading dustpan unloading speed is slow, derrick is not produced impacts, do not increase derrick height during unloading, bend unloads automatically that dustpan unloading speed is fast, derrick produced during unloading impact, the increase derrick height.Therefore need a kind of self-powered top-opened fan gate skip and solve the problem that dustpan unloading speed is slow, need install on derrick discharging gear, increase derrick height when unloading.
Summary of the invention
The purpose of this utility model is that a kind of self-powered top-opened fan gate skip will be provided, and this skip bucket is self-powered, and discharge rate is fast, do not need to install discharging gear during unloading on derrick, does not increase derrick height, and derrick is not produced impact.
The purpose of this utility model is achieved in that this skip bucket comprises framework and bucket case, the bucket case is fixed in the framework, sector gate is installed in bucket coal unloading hole place, lower box part side by axis of revolution, sector gate comprises two fan-shaped side plates, two fan-shaped side plate front ends are connected with arc plate, and fan-shaped side plate rear end is connected with the unloading axle, is connected with cylinder between the unloading axle of sector gate and the framework, pipeline one end is connected with the cylinder porting, and the other end is fixed on going up of framework and coils top.
The utility model is self-powered, and is simple in structure, and self-locking property is good, and is safe and reliable, and the unloading quick and stable does not have and spills the coal phenomenon, need not to increase derrick height, during unloading derrick is not produced impact.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sector gate structural representation among Fig. 1.
Fig. 3 is Fig. 2 left view.
1. frameworks among the figure, 2. bucket case, 3. sector gate, 4. cylinder, 5. pipeline, 6. fan-shaped side plate, 7. arc plate, 8. axis of revolution, 9. unloading axle, 10. dish on the bearing, 11..
The specific embodiment
In Fig. 1, Fig. 2 and Fig. 3, bucket case 2 is fixed in the framework 1 by welding or bolt.Sector gate 3 is installed in bucket case 2 lower side coal unloading hole places by axis of revolution 8.Unloading axle 9 on cylinder 4 heads and the sector gate 3 is hinged, and the bearing 10 on cylinder 4 afterbodys and the framework 1 is hinged.Two pipelines, 5 one ends are connected with cylinder 4 portings, and the other end is fixed on going up of framework 1 and coils 11 tops.
Two fan-shaped side plate 6 front ends are connected with arc plate 7, two fan-shaped side plates 6 and arc plate 7 welding.Axis of revolution 8, unloading axle 9 pass the rear end of two fan-shaped side plates 6.Arc plate 7 can be strengthened with reinforced rib.Axis of revolution 8 is captiveed joint with bucket case 2 by axle sleeve, baffle plate, axle sleeve and 2 welding of bucket case.Two fan-shaped side plates 6 can wraparound rotating shaft 8 rotations.Unloading axle 9 is captiveed joint with two fan-shaped side plates, 6 rear ends by axle sleeve, baffle plate.
During work, cylinder 4 draws to shirk and carries axle 9 under the effect of load, makes gate 3 rotations.The pipeline of going up on the dish 11 5 that is fixed on framework 1 is provided with adaptor union.This skip bucket provides pressurized air by well head gas control device.When skip bucket arrives the well head unloading position, well head gas control cabinet flexible pipe be fixed on the skip bucket framework on the pipeline 5 that coils dock, by the electromagnetism Pneumatic valve, make cylinder 4 actions, unloading axle 9 on the cylinder 4 pulling sector gates 3, make sector gate 3 wraparound rotating shafts 8 rotations, sector gate 3 is upwards opened, and coal is discharged into coal bunker by deadweight.After the completion of discharge, Pneumatic valve is reverse, and the unloading axle 9 that cylinder 4 promotes on the sector gate 3 resets sector gate 3.
