Abstract
The present invention relates to workshop human relocation project.Ultra-large type crane girder slides method for dismounting in a kind of small space, it includes: step 1, and using former cooling bed device fixed beam and Equipment Foundations, slippage bracket is laid in fixed beam；Step 2 is laid with two tracks on slippage bracket, is laid with thick track snap-gauge layout and track is fixed on slippage bracket；Step 3 places two sliding trolleys on slippage bracket, and crane girder is put down with loop wheel machine and fallen on sliding trolley by two sides, and crane girder is fixed with trolley；Step 4, continue the track for being laid with certain length on one end vacant lot of slippage bracket, and hoist engine is set at track both ends, one end hoist engine is responsible for drawing crane girder to designated place, and other end hoist engine provides certain resistance to be responsible for control crane girder sliding velocity；Two loop wheel machines transport crane girder entrucking after crane girder slides onto designated place.The present invention realizes the smooth dismounting of the large-scale component in the case where place is limited and needs protective demolition component.
Description
Technical field
The present invention relates to a kind of methods that workshop human relocation project more particularly to crane girder are removed.
Background technique
At present for the mounting technique of large scaled crane beam and experience comparative maturity, and for the guarantor of ultra-large type crane girder
It is not perfect that shield property removes resettlement technology, especially upper space is limited, lower part equipment needs to protect, loop wheel machine is without advantageous erect-position
It is especially insufficient etc. the large scaled crane beam protective demolition experience under the conditions of multiple restricted clearance.Recently as urbanization process
The requirement of quickening and urban development, numerous industrial premises start to move successively, wherein being just related to large scaled crane beam in workshop
Dismounting.Such as just there is above situation in Pu steel removal project, ultra-large type crane girder weight cannot after causing crane girder to remove again
It directly falls in equipment, multiple restricted clearance causes huge loop wheel machine not to be available, so conventional dismounting hoisting technology can not expire
This engine request of foot.
Summary of the invention
Present invention seek to address that the defect of the prior art, ultra-large type crane girder sliding dismounting side in a kind of small space is provided
Method.The present invention realizes the smooth dismounting of the large-scale component in the case where place is limited and needs protective demolition component, and the method is also
It can be applied to the installation exercise of the large-scale component in existing device region.
Ultra-large type crane girder slides method for dismounting method in a kind of small space of the present invention, it includes:
Step 1 is laid with slippage bracket, slippage bracket using former cooling bed device fixed beam and Equipment Foundations in fixed beam
Using twice H profile steel as girder, web member is made using H profile steel in centre, and slippage bracket is concordant with fixed beam end on one side, another side
There is being padded with support sole plate for spacing with Equipment Foundations；
Step 2 is laid with two tracks on slippage bracket, is laid with having spacing with thick track snap-gauge, track is fixed on
On slippage bracket；
Step 3 places two sliding trolleys, two sliding trolley centre distance slippage bracket both ends on slippage bracket
Distance is that the position of slippage bracket overall length 1/4 is placed, and crane girder is put down with loop wheel machine and fallen on sliding trolley by two sides, is added with transport
Clamped frame is fixed with trolley by crane girder；
Step 4 continues the track for being laid with certain length on one end vacant lot of slippage bracket, and is arranged at track both ends
Hoist engine, one end hoist engine are responsible for drawing crane girder to designated place, and other end hoist engine provides certain resistance to be responsible for control
Crane girder sliding velocity processed is drawn as protectiveness；Two loop wheel machines transport crane girder entrucking after crane girder slides onto designated place
It is defeated.
Ultra-large type crane girder slides method for dismounting method in a kind of small space, is easy for assemble or unload, step
In two, the slippage bracket of setting is divided into two sections, and centre is bolted fixation with rack connecting plate and connection.
The present invention is lifted using two loop wheel machines in crane girder two sides by setting up auxiliary sliding facility on cooling bed device
Method so far slides crane girder decentralization on facility, then slides to the place for meeting conventional lifting and transport, last entrucking fortune again
It is defeated.
Further, since generally need to first install crane girder in traditional industry construction of hydropower excavates large scale equipment foundation pit again, use
The method can realize first carry out foundation construction after carry out large-scale component lifting saved the duration to optimize process.
Specific embodiment
Ultra-large type crane girder slides method for dismounting method in a kind of small space of the present invention, it includes:
Step 1 is laid with slippage bracket, slippage bracket using former cooling bed device fixed beam and Equipment Foundations in fixed beam
Using twice H profile steel as girder, web member is made using H profile steel in centre, and slippage bracket is concordant with fixed beam end on one side, another side
There is being padded with support sole plate for spacing with Equipment Foundations；
Step 2 is laid with two tracks on slippage bracket, is laid with having spacing with thick track snap-gauge, track is fixed on
On slippage bracket；
Step 3 places two sliding trolleys, two sliding trolley centre distance slippage bracket both ends on slippage bracket
Distance is that the position of slippage bracket overall length 1/4 is placed, and crane girder is put down with loop wheel machine and fallen on sliding trolley by two sides, is added with transport
Clamped frame is fixed with trolley by crane girder；
Step 4 continues the track for being laid with certain length on one end vacant lot of slippage bracket, and is arranged at track both ends
Hoist engine, one end hoist engine are responsible for drawing crane girder to designated place, and other end hoist engine provides certain resistance to be responsible for control
Crane girder sliding velocity processed is drawn as protectiveness；Two loop wheel machines transport crane girder entrucking after crane girder slides onto designated place
It is defeated.
Ultra-large type crane girder slides method for dismounting in a kind of small space, to be easy for assemble or unload, in step 2,
The slippage bracket of setting is divided into two sections, and centre is bolted fixation with rack connecting plate and connection.
The present invention is lifted using two loop wheel machines in crane girder two sides by setting up auxiliary sliding facility on cooling bed device
Method so far slides crane girder decentralization on facility, then slides to the place for meeting conventional lifting and transport again, can entrucking fortune
It is defeated.There is preferable reference for the resettlement of industrial premises protective demolition in the future, while component reuses and also saves again
A large sum of expense, meets the environmental protection concept of green construction required for production.
