Description
Technical field
The utility model relates to the clear storehouse device of a kind of storage vault or technology feed bin, particularly a kind of efficient storehouse wall swabbing pig.
Background technology
At present, the storage vault of domestic different shape and various versions or technology feed bin are after long-time the use, thicker material is detained in the capital on storehouse wall or bulkhead, cause the storage power in storehouse or storehouse to reduce, the materials inside that also can influence storehouse or storehouse flows, even causes stopping production.The material that the storehouse that has is detained is very thick, and has certain intensity, is difficult to clean out.In order to recover the storage power in these storehouses, must regularly clear up effectively.Traditional clear storehouse mode is that the people enters in the storehouse, is sling to be suspended in manual clear material in the storehouse, and this is an extremely dangerous job, and cleaning effect is bad.On the one hand, the delay material that has slump to get off at any time can't ensure the person and life security; On the other hand, the place that the people can touch is very limited, and the material that is detained on the wall of most storehouses can not be cleared up.For a long time, the storehouse problem is perplexing enterprises such as numerous cement mill, stope, grain storehouse always clearly.
Summary of the invention
Technical problem to be solved in the utility model is: adopt the clear storehouse of machinery mode, only need people's remote manipulation on the top, storehouse, just can safety, effectively on the wall of whole storehouse all are detained materials and clean out, and can 100% recover the efficient storehouse wall swabbing pig of the design storage power of storage vault.
The technical scheme that the utility model adopted is: a kind of efficient storehouse wall swabbing pig, it is characterized in that including top, storehouse connecting element, the telescopic boom suspension bracket, the suspension bracket rotary handle, turn a pulley set, the telescopic boom pull bar, hose reel, the hose reel support, the changed course pulley, serving rolls group, serving rolls pack support, the serving assembly pulley, the changed course assembly pulley, changed course assembly pulley support, compressed-air hose, hose sheave and swabbing pig part, the concrete connection is: top, storehouse connecting element is fixed on top, storehouse manhole aperture of door periphery, the telescopic boom suspension bracket is fixedly hung on the intermediate beam of top, storehouse connecting element, with the hose reel support be the two ends that the supporting leg of the hose reel support of one is fastened in the intermediate beam of top, storehouse connecting element, there is detouchable suspension bracket rotary handle the upper end of telescopic boom suspension bracket, hose reel is fixed on the hose reel support, serving rolls group, the serving assembly pulley is fixed on serving and rolls on the pack support, and rolling pack support, serving is fixed on hose reel support and the supporting leg thereof, the changed course assembly pulley support that is fixed with the changed course pulley is fixed on telescopic boom suspension bracket place, the changed course pulley is fixed on the hose reel support, telescopic boom pull bar and turn the lower end that a pulley set is fixed on the telescopic boom suspension bracket, compressed-air hose one end is positioned at the hose reel place, again by the changed course assembly pulley, hose sheave connects the swabbing pig part at the other end.
Efficient storehouse wall swabbing pig adopts the clear storehouse of machinery mode, does not need the people to enter in the storehouse, and the people just can the remote manipulation swabbing pig on the top, storehouse, avoided because the material that collapses, suffocate, personnel that chemical substance, material such as inflammable and explosive cause injure and fatal risk.Energy 100% ground recovers the design storage power of bank.Telescopic boom and pneumatic blowing type swabbing pig can cover whole storehouse wall flexibly, and telescopic boom can be around 360 ° of storehouse wall rotations, and 50 meters of swabbing pig liftables are applicable to storage vault or the storehouse of clearing up difformity, different structure form and different size.Can finish storehouse work clearly efficiently, rapidly.Swabbing pig is a kind of pneumatic blowing type, by compressed air, the pilot blade that promotes swabbing pig drives cleaning pipe high speed revolution, and constantly impacts, lashes, smashes the material that is detained on the wall of storehouse by cleaning head, pressurized air is constantly discharged from cleaning head simultaneously, and the storehouse wall is cleaned out.The material of clearing up does not pollute, and the system that can enter utilizes again, and the benefit that these materials bring maybe can satisfy the cleaning expense that this storehouse took place.According to the actual conditions needs, clear storehouse also can stop production.Promptly under the situation of storehouse charging simultaneously, discharging, cleaning storehouse wall is cleared up storehouse wall efficient height.This is that artificial clear storehouse can't be realized.Portable design adopts lightweight material, is easy to carrying, assembling and dismounting.The electrostatic prevention design also is applicable to inflammable, explosive material bank cleaning, as coal dust storehouse, cereal storehouse etc.
