Abstract
The utility model discloses a chamber roof truss overall declining removal device of a large gas chamber, belonging to the technical field of the gas chamber removal technology. The removal device comprises a lifting frame, a chain block, a declining wire rope, a suspension lifting lug and a temporary hanging steel wire rope. The lifting frame is welded at the top end of a gas chamber upright column, one end of the chain block is hung on a hoisting hole of the lifting frame by a lifting hook, and the other end of the chain block is hung at one end of the declining steel wire rope; the other end of the declining steel wire rope is connected with the lifting hole in a chamber roof truss ring beam by a snap ring; the suspension lifting lug is welded on the gas chamber upright column, one end of the temporary hanging steel wire rope is hung at the suspension lifting lug, and the other end of the temporary hanging steel wire rope is connected with the other hoisting hole in the tank chamber truss ring beam by the snap ring. The removal device has the advantages that the difficulty of hoisting and unloading a whole chamber roof truss of a large-tonnage long-span gas chamber is effectively solved, the working efficiency is enhanced, and the construction cost is saved.
Description
Technical field
The utility model belongs to gas chamber demolition technique field.Be particularly related to the whole decline detaching device of a kind of large gas holder top truss.
Background technology
The potential safety hazard that the gas chamber Demolition Construction relates to is more, has both related to aloft work, relates to again the construction in inflammable and explosive zone.Especially the top of gas cabinet trussed steel beam is because of characteristics such as it is highly high, span large, Heavy Weights, the whole dismounting that descends is the difficult point of engineering, as use wheel crane to carry out the cabinet top truss and remove operation, not only cost is high, be subject to simultaneously the place restriction, and several wheel crane while coordinating operations, synchronism is restive, slightly has deviation easily accidents caused.
Summary of the invention
The purpose of this utility model is to provide a kind of large gas holder top truss whole decline detaching device.Overcome the whole difficult point that descends, a kind of device of simple in structure, easy to operate, time saving and energy saving cabinet top truss overall pulling down is provided.
The utility model comprises mast-up, chain block, decline steel rope, hangs hanger and hang steel rope temporarily.Mast-up is welded on the top of gas chamber column, and chain block one end hangs over suspension hook on the lifting hole(eyelet) of mast-up, and an other end is hung an end of decline steel rope; The other end of decline steel rope is connected with hole for hoist on the cabinet top truss collar tie beam with snap ring; Hang hanger and be welded on the gas chamber column, hang steel rope one end temporarily and hang on the suspension hanger, an other end is connected with another hole for hoist on the cabinet top truss collar tie beam with snap ring.
Two holes for hoist are also shown in the top of the corresponding gas chamber column of cabinet top truss collar tie beam direction.
The decline steel rope is independent wire strand, and length will surpass the gas chamber height, and steel rope need satisfy the lifting tonnage demand, and leaves and be not less than 20% safety factor.
But the decline steel rope is connected with the force-loose wire rope grip with chain block.
The stroke of chain block is not less than the distance of top of gas cabinet and interim sling point.
Hanging the descending stroke of determining according to chain block and cabinet platform the hanger position welds in the gas chamber column outside.
In the process that descends, the gravity of cabinet top truss is born by mast-up and chain block.Wait to drop to when hanging the hanger position, will hang hanger and be connected with snap ring with another hole for hoist of cabinet top truss collar tie beam by hang steel rope temporarily, this moment is stressed for hang hanger and hang steel rope temporarily.Chain block is resetted, and next trip distance needs is satisfied in the decline steel rope that will be connected with chain block prolongation.Operation lifts chain block makes decline steel rope and cabinet top truss stressed, pulls down and hangs steel rope temporarily, carries out next step step-down operation again.Repeatedly carry out this process, until the cabinet top truss is drop to ground.
The utility model has the advantage of: efficiently solve the difficult problem of large-tonnage, the whole unloading of wide span coal gas holder top truss, improved work efficiency, and saved construction cost.

The specific embodiment
Fig. 1-Fig. 5 is a kind of specific embodiment of the present utility model.
Embodiment 1:
The utility model comprises mast-up 1, chain block 2, decline steel rope 3, hangs hanger 6 and hang steel rope 7 temporarily.Mast-up 1 is welded on the top of gas chamber column 8, and chain block 2 one ends hang over suspension hook on the lifting hole(eyelet) of mast-up 1, and an other end is hung an end of decline steel rope 3; Decline steel rope 3 other ends are connected with hole for hoist on the cabinet top truss collar tie beam 5 with snap ring; Hang hanger 6 and be welded on the gas chamber column 8, hang steel rope 7 one ends temporarily and hang on the suspension hanger 6, an other end is connected with another hole for hoist on the cabinet top truss collar tie beam 5 with snap ring.
The hole for hoist of two Ф 30mm is also shown in the top of cabinet top truss collar tie beam 5 corresponding gas chamber column 8 directions.
But decline steel rope 3 is connected with the force-loose wire rope grip with chain block 2.
The stroke of chain block 2 is not less than the distance of top of gas cabinet and interim sling point.
In the process that descends, the gravity of cabinet top truss 4 is born by mast-up 1 and chain block 2.Wait to drop to when hanging hanger 6 position, will hang hanger 6 and be connected with snap ring with cabinet top truss collar tie beam 5 another holes for hoist by hang steel rope 7 temporarily, this moment is stressed for hang hanger 6 and hang steel rope 7 temporarily.Chain block 2 is resetted, and next trip distance needs is satisfied in decline steel rope 3 prolongations that will be connected with chain block 2.Operation lifts chain block 2 makes decline steel rope 3 and cabinet top truss 4 stressed, pulls down and hangs steel rope 7 temporarily, carries out next step step-down operation again.Repeatedly carry out this process, until cabinet top truss 4 is drop to ground.
