Abstract
The utility model relates to a prefabricated decking hoist with adjustable, longeron including two parallel arrangement, a fixed lug is welded respectively to every longeron both ends top surface, it welds a set of crossbeam respectively to be close to two longeron both ends between two longerons, every group crossbeam includes 3 at least parallel arrangement's crossbeam, there is certain clearance between adjacent crossbeam, be provided with two movable lugs between two adjacent crossbeams in every group crossbeam, every movable lug includes a spacing roof beam, a spacing roof beam bottom welding otic placode, spacing roof beam both ends are supported at two crossbeam top surfaces, the otic placode passes the clearance between two crossbeams and extends to the crossbeam below and connect one and break out. The utility model discloses can adapt to the hoist and mount of unidimensional prefabricated decking, can practice thrift the hoist cost to convenient construction.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a hoist and mount construction of prefabricated decking is related to, concretely relates to prefabricated decking hoist with adjustable.
Background
And hoisting the concrete prefabricated bridge deck of the steel-concrete composite beam by adopting a crane in the processes of transferring and installing after prefabrication. 4 rings that set up according to four summits of rectangle are predetermine usually to prefabricated bridge deck slab top surface, lift by crane the in-process, adopt special hoist usually, 4 lugs are established to the hoist bottom and are connected with the rings on the decking respectively, for the extrusion force that avoids or reduces the decking as far as possible and receive in the horizontal direction, the lug of hoist bottom should lay the interval unanimously with the rings on the decking. However, the bridge deck has various sizes, and the distances between the lifting lugs on the bridge deck with different sizes are different, so that lifting appliances with different specifications need to be arranged aiming at the bridge decks with different sizes, the construction cost is increased, and the construction is inconvenient due to frequent replacement of the lifting appliances.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide a prefabricated decking hoist with adjustable, adaptable not unidimensional decking hoist and mount facilitate for the construction.
The technical scheme of the utility model as follows:
the utility model provides a prefabricated decking hoist with adjustable which characterized in that: including two parallel arrangement's longeron, a fixed lug is welded respectively to every longeron both ends top surface, is close to two longerons both ends and welds a set of crossbeam respectively between two longerons, and every group crossbeam includes 3 at least parallel arrangement's crossbeam, has certain clearance between adjacent crossbeam, is provided with two and can follows crossbeam longitudinal sliding's activity lug in every group crossbeam between two adjacent crossbeams, and every activity lug includes a spacing roof beam, a spacing roof beam bottom welding otic placode, the spacing roof beam both ends are supported respectively at two crossbeam top surfaces, the otic placode passes the clearance between two crossbeams and extends to the crossbeam below, and the otic placode lower extreme establishes one and breaks out the connecting hole to connect one through breaking out the connecting hole and break out.
The utility model discloses a to move about between the lug inserts different crossbeams, the longitudinal separation of lug on the adaptable decking, through the slip of activity lug between two crossbeams, the horizontal interval of lug on the adaptable decking to a hoist can adapt to not unidimensional prefabricated decking hoist and mount, can practice thrift the hoist cost, and convenient construction.

Detailed Description
As shown in fig. 1, fig. 2, fig. 3, fig. 4, the utility model discloses a two parallel arrangement's longeron 1, a fixed lug 2 is welded respectively to 1 both ends top surface of every longeron, it welds a set of crossbeam respectively to be close to two longeron both ends between two longerons, every group crossbeam includes 3 at least parallel arrangement's crossbeam 3, there is certain clearance between adjacent crossbeam, be provided with two movable lugs 4 that can follow crossbeam longitudinal sliding in every group crossbeam between two adjacent crossbeams, every movable lug includes a spacing beam 41, a spacing beam bottom welding otic placode 42, spacing beam 41 both ends are supported respectively at two crossbeam 3 top surfaces, otic placode 42 passes the clearance between two crossbeams 3 and extends to the crossbeam below, and an shackle connecting hole 43 is established to the otic placode lower extreme to connect an shackle 5 through the shackle connecting hole in the embodiment shown in fig. 1, the crossbeam is equipped with 5 crossbeams. The larger the number of the cross beams is, the larger the selectable range of the longitudinal distance of the movable lifting lug between the two groups of the cross beams is.
As shown in fig. 5, the utility model discloses during the use, according to waiting to lift by crane the interval of laying of rings on the decking 6, select to insert movable lug 4 between two crossbeams in every group crossbeam, the longitudinal separation who makes the movable lug on two sets of crossbeams equals with the longitudinal separation of the rings on the suspension bridge panel, along crossbeam longitudinal sliding movable lug, the interval that makes two movable lugs between two crossbeams equals with the horizontal interval of the rings on the decking, then be connected 4 movable lugs respectively with rings on the decking through breaking out 5, fixed lug 2 on two longerons is connected with the loop wheel machine through the lifting rope respectively.
