Description
Technical field
The present invention relates to prevent blocking of coal bunker dredging technology, particularly relate to a kind of coal bunker automatic block clearing machine.
Background technology
Current domestic thermal powerplant coal bunker is mostly cement steel hybrid combination, and its planform is basic identical, and top is cylindrical, and it is conical that bottom is.Coal bunker is suitable for reading, end opening is used for respectively into coal, row's coal, and coal falls by deadweight from top to bottom.Owing to containing relatively large coal slime in coal, thus coal in dropping process easily because coal bunker is stopped up in extruding.Coal bunker chute blockage is the operating FAQs in coal-burning power plant, chute blockage often with bulkhead cohere, frame coal, canopy coal, caking, jam form occur.Be interrupted in short-term coal and can cause boiler load and operational factor fluctuation, disconnected coal even can cause boiler flameout for a long time, and impact is normally produced.
From front, many to the technical study of coal bunker block clearing, mainly contain three kinds of bunker wall vibration devices, air bubble, coal bunker loosening machine.The coal that bunker wall vibration device mainly makes to cohere on bulkhead by the vibrations of bulkhead departs from gradually, but bunker wall vibration device must be in its effect of position competence exertion of knot arch, and the knot of coal bunker arch position is uncertain, and constantly change, therefore the block clearing effect of bunker wall vibration device is poor, and easily cause bulkhead to damage.Air bubble carries out block clearing by blocking position in the direct impacting house of high velocity air of ejection.But air bubble also must be in its effect of the position competence exertion of knot arch, its block clearing effect is poor, also easily causes bulkhead to damage.Coal bunker loosening machine in the straight reciprocating motion of coal bunker inwall, recovers flowing of coal by hydraulic-driven coal plough; Due to coal bunker bottom the angle of the position of easy chute blockage often change, therefore the block clearing effect of coal bunker loosening machine is poor.
As can be seen here, in prior art, there is the problems such as block clearing weak effect in coal bunker block clearing.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of coal bunker automatic block clearing machine of good blocking cleaning effect.
In order to achieve the above object, the technical scheme that the present invention proposes is:
A kind of coal bunker automatic block clearing machine, comprise: for connecting coal bunker and being provided with the fixed mount of interstitial hole, be used to the first turning unit, the second turning unit provides the rotary oscillation oil cylinder of rotary power, for revolving round the sun under the effect at rotary oscillation oil cylinder and swing link, the first turning unit that drives the second turning unit to move up and down under the effect of the first HM Hydraulic Motor, for revolving round the sun under the drive of the first turning unit, move up and down and under the effect of the second HM Hydraulic Motor, carry out the second turning unit of rotation, be used for connecting rotary oscillation oil cylinder and the first turning unit, for the first turning unit and the second turning unit provide the swing link that swings power, be used to the first turning unit to drive the second turning unit to move up and down the first HM Hydraulic Motor of power is provided, be used to the second turning unit that the second HM Hydraulic Motor of rotation power is provided, wherein, the first HM Hydraulic Motor is installed on the first turning unit top, and the second HM Hydraulic Motor is installed on the second turning unit top, rotary oscillation oil cylinder is positioned at the top of fixed mount, and the first turning unit, the second turning unit, swing link, the first HM Hydraulic Motor, the second HM Hydraulic Motor are positioned at the below of fixed mount, swing between the interstitial hole of link by fixed mount and rotary oscillation oil cylinder and be connected by the first flange.
In sum, in coal bunker automatic block clearing machine of the present invention, swing link for the first turning unit provides swing power, make the first turning unit to extrinsic deflection certain angle; Meanwhile, rotary oscillation oil cylinder provides rotary power for the first turning unit; Therefore, the first turning unit is rotated with certain deflection angle, realizes revolution.Under the drive of the first turning unit, the second turning unit has also been realized revolution; Meanwhile, under the effect of the second HM Hydraulic Motor, the second turning unit carries out rotation.In addition, under the effect of the first HM Hydraulic Motor, the first turning unit can also drive the second turning unit to move up and down.Revolution, the autobiography of the second turning unit and moving up and down, makes larger to the loose scope of coal in coal bunker, the loose effect of coal bunker automatic block clearing machine of the present invention relatively good.
