Abstract
The utility model relates to a hoist suitable for not unidimensional prefabricated decking hoist and mount, including 4 piece at least parallel arrangement's longeron, the welding has the main beam between the tip of each longeron orientation same direction, and two fixed otic placodes of every longeron top surface symmetric welding wear to establish two movable otic placodes on the every longeron, and every movable otic placode is located a fixed lug and between the longeron tip that closes on with this fixed lug, and can follow longeron longitudinal sliding, and the lower extreme of every movable otic placode extends to below the bottom surface of longeron and establishes an and breaks out the mounting hole. The utility model discloses can select suitable otic placode to lift by crane according to the lug interval on the decking to can be applicable to not unidimensional prefabricated decking hoist and mount.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a hoist that applicable hoist in the hoist and mount of not unidimensional prefabricated decking is related to.
Background
After the concrete bridge deck slab of the steel-concrete composite beam is prefabricated in a prefabricating yard, a crane is required to hoist during transportation and installation. The deck slab is generally provided with 4 lifting eyes symmetrically for connecting a special lifting appliance. However, the bridge deck of different bridges has different sizes, and even if the bridge deck of the same bridge at different positions has different sizes, for example, the widths of the bridge deck of a sidewalk and the bridge deck of a driveway are different, the distances between lifting lugs on the bridge deck are also different correspondingly. If a lifting appliance is arranged independently according to the bridge deck with each size, not only can the cost be increased, but also the construction is inconvenient because the lifting appliance is frequently replaced.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide an applicable hoist in the hoist and mount of not unidimensional prefabricated decking, facilitate for the construction.
The technical scheme of the utility model as follows:
the utility model provides a hoist suitable for not unidimensional prefabricated decking hoist and mount which characterized in that: including 4 piece at least parallel arrangement's longeron, the welding has the main beam between the tip of each longeron orientation same direction, and two fixed otic placodes of every longeron top surface symmetric welding wear to establish two activity otic placodes on every longeron, and every activity otic placode is located a fixed lug and with between the longeron tip that this fixed lug closes on, and can follow longeron longitudinal sliding, and the lower extreme of every activity otic placode extends to below the bottom surface of longeron and establishes an shackle mounting hole.
The utility model discloses be provided with the otic placode of the different intervals of multiunit, can select appropriate otic placode to lift by crane according to the lug interval on the decking to can be applicable to not unidimensional prefabricated decking hoist and mount.

Detailed Description
As shown in fig. 1, the utility model discloses an at least 4 parallel arrangement's longeron 1, the welding has main beam 2 between the tip of each longeron orientation same direction, two fixed otic placodes 3 of every longeron top surface symmetric welding, wear to establish two movable otic placodes 4 on the every longeron, every movable otic placode 4 is located a fixed lug and between the longeron tip that closes on with this fixed lug, and can follow longeron longitudinal sliding, the lower extreme of every movable otic placode 4 extends to below the bottom surface of longeron and establishes a shackle mounting hole 41.
In the embodiment shown in fig. 1, 4 longitudinal beams 1 are provided, which can be applied to bridge decks of two sizes, wherein the distance between the two longitudinal beams on the outer side is consistent with the distance between the transverse lifting lugs on the bridge deck of the roadway, and the distance between the two longitudinal beams on the inner side is consistent with the distance between the transverse lifting lugs on the bridge deck of the roadway.
The utility model discloses during the concrete implementation, still can set up more longerons to be applicable to the decking of more sizes, the interval of two longerons in the outside can set up to unanimous with the lug interval on the biggest decking, and the interval of two longerons in the innermost can set up to unanimous with the lug interval on the minimum decking.
The utility model discloses during the concrete implementation, according to the length of longeron, still can weld one, two or many strengthening beam 5 between each longeron to guarantee the overall structure intensity of hoist.
As shown in fig. 2 and fig. 3, in the specific implementation of the present invention, the longitudinal beam 1 can be made of i-shaped steel, and accordingly, the movable ear plate 4 is provided with an i-shaped insertion hole 42 having the same cross section as the i-shaped steel of the longitudinal beam and is inserted into the longitudinal beam through the i-shaped insertion hole.
As shown in fig. 4, the utility model discloses during the use, according to waiting to lift by crane the lug interval on the decking 6, wear to establish shackle 7 on fixed otic placode 3 and the activity otic placode 4 on the longeron of two corresponding intervals respectively, the shackle on the fixed otic placode passes through the lifting rope and is connected with the loop wheel machine, and the shackle on the activity otic placode is connected with the lug on the decking. Because the lifting lugs on the bridge deck slab have certain deviation along the longitudinal distance of the bridge deck slab when the bridge deck slab is prefabricated, when the movable lug plate is connected with the lifting lugs on the bridge deck slab, the movable lug plate can properly slide along the longitudinal beam, the lifting stress direction of the lifting lugs is ensured to be vertical to the slab surface of the bridge deck slab, and the bridge deck slab is protected to the maximum extent.
