Abstract
The invention relates to a nuclear power station module suspender. The suspender is characterized in that the suspender comprises seven crossbeams, four lower suspension plates, two middle suspension forks, one upper suspension plate, one upper suspension fork and pins. All above members are connected to form an integral body, so the suspender has the advantages of no component slipping, large bearing capability and high working safety. When the suspender is disassembled after use and is stored, the pins and accessories thereof can be filled to a case or are withdrawn to a warehouse, and the seven crossbeams can be stably and uprightly placed in the storage place for a long term, so the occupied land area is small.
Description
Technical field
The present invention relates to a kind ofly in the work progress of nuclear station, be used for the instrument that construction module is lifted.

The form that three generations's nuclear power adopts modularization to build, wherein, nuclear station part-structure module volume is large, Heavy Weight, suspension centre are many, and the relative center of gravity of suspension centre is asymmetric, need to many hoisting beams combine form combined sling could be with large crane that this equipment lifting is in place.Employed CA20/CA01 module suspender during at present AP1000 construction, part in design comes with some shortcomings, cause beam from great, center of gravity is high, the bottom width relative narrower, if stand up poor stability when depositing, keep flat for a long time and produce easily the permanent bend distortion, affect its Lifting Capacity, also have some potential safety hazards in combination, the use, following boatswain chair location inaccuracy, easy slippage etc.
Summary of the invention
The purpose of this invention is to provide a kind ofly be convenient to deposit, load-carrying capacity is large and operational security is high, be used for the instrument of nuclear station construction module lifting.
In order to achieve the above object, technical scheme of the present invention has provided a kind of nuclear power station module suspender, it is characterized in that: comprising that seven crossbeams, four pairs of lower boatswain chairs, two are merely hit hangs fork, one pair of upper boatswain chair, hang oneself fork and a bearing pin; The concentricity line of fork, upper boatswain chair and entablatrance of hanging oneself arranges that upper boatswain chair upper end links by a bearing pin and the fork of hanging oneself, and its lower end and entablatrance are by being positioned at two bearing pins and the entablatrance binding on the same level line; The upper end that two merely hit hangs fork is attached at respectively the left and right two ends of entablatrance by bearing pin separately, and two center members bearing pin by separately is attached at respectively two and merely hits and hang the lower end of fork, and the lower loop wheel machine structures of two covers that structure is identical are connected with a center member respectively;
The loop wheel machine structure comprises lower boatswain chair one, lower boatswain chair two, cross sill one, cross sill two, circular hoisting belt, fixed type hanger and bearing pin under every cover; The upper end of lower boatswain chair one and lower boatswain chair two is attached at respectively the left and right two ends of center member by bearing pin separately, cross sill one and cross sill two bearing pin by separately is connected with the lower end of lower boatswain chair one and lower boatswain chair two respectively, and lower boatswain chair one is arranged with cross sill two respectively concentricity lines with cross sill one and lower boatswain chair two; The fixed type hanger is inserted thoroughly from cross sill one and cross sill two respectively, is welded and fixed respectively between fixed type hanger and cross sill one and the cross sill two, and circular hoisting belt and fixed type hanger link by bearing pin.
Preferably, the version of described entablatrance and described center member is designed to the variable section constant strength beam.
Preferably, the height to width ratio of described entablatrance and described center member is 1: 3～2: 5.
Can form an integral body after all members of the present invention connect, without possibility slippage parts, not only load-carrying capacity is large, and operational security is high.Suspender provided by the invention with after disassemble and open when depositing, the warehouse can be cased or regain to bearing pin and annex thereof, seven crossbeams can stand up in the storage space long-term stability, floor area is little.
