Description
Technical field
The utility model relates to bridge truss turn over aid field more particularly to a kind of steel truss girder purlin piece turnover hoistings
Structure.
Background technique
Currently, when being converted to vertical position progress section assembling, being generally required special after the completion of steel truss girder purlin piece prosposition is assembled
Purlin piece overturning tire is completed to realize, not only needs to design special tooling, also need special place when turning and turning over, turn
In vertical position, state is transported to assembled place afterwards, can only be by loop wheel machine air transport, and difficulty and security risk are all bigger, corresponding to take
With can also greatly increase.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of steel truss girder purlin piece turnover hoisting structures, are able to solve one
As the piece switching process of steel truss girder purlin in turn over need dedicated site and special turning tool, the big problem of difficulty Risks.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of steel truss girder purlin piece turnover hoisting structure,
Steel truss girder includes top boom, lower boom, web member and brace；Its innovative point in: further include lifting lug, the lifting lug have several and
It is separately positioned on top boom and lower boom；Direction that the lifting lug is arranged on top boom and the direction being arranged on lower boom are mutual
It is perpendicular；
It is provided with two groups of lifting lugs on the top boom and is arranged perpendicular to the upper surface of top boom, every group of lifting lug setting
There are two the first lifting lug unit and the second lifting lug unit parallel to each other, the first lifting lug unit of the lifting lug group on top boom is located at
The surface of web member and top boom joining place, the second lifting lug unit are located at the side of the first lifting lug unit；
Setting is arranged there are two lifting lug and perpendicular to the side surface of lower boom on the lower boom, two on the lower boom
A lifting lug is respectively third lifting lug unit and the 4th lifting lug unit；The third lifting lug unit and the 4th lifting lug unit and top boom
On two groups of lifting lugs interlock in the extending direction position of chord member；
Lifting lug unit includes a pair of otic placode parallel to each other and the connecting rod that is vertically connected between otic placode.
Further, it is welded between the connecting rod and otic placode using penetration.
Utility model has the advantages that
1) it ensure that in the utility model by being staggeredly equipped with lifting lug respectively on the top boom and lower boom of steel truss girder
Lifting lug accepts stability in lifting；In addition, web member is arranged in lifting lug on top boom and the junction of chord member ensure that stress
Steel truss girder is lifted by crane in the position of the reasonability of point impetus, lifting lug, ensure that the web member and brace in steel truss girder are not susceptible to deformation；
It does not need to occupy special place yet.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is a kind of gooseneck purlin piece turnover hoisting structure of the utility model.

It is orthogonal to state the direction being arranged on the direction and lower boom 2 that lifting lug 4 is arranged on top boom 1.
It is provided with two groups of lifting lugs on top boom 1 and is arranged perpendicular to the upper surface of top boom 1, every group of lifting lug 4 setting
There are two the first lifting lug unit 41 and the second lifting lug unit 42 parallel to each other, the first lifting lug list of the lifting lug group on top boom 1
Member 41 is located at the surface of web member and 1 joining place of top boom, and the second lifting lug unit position 42 is in the side of the first lifting lug unit 41.
Setting is arranged there are two lifting lug and perpendicular to the side surface of lower boom 2 on lower boom 2, two on the lower boom 2
A lifting lug is respectively third lifting lug unit 43 and the 4th lifting lug unit 44；The third lifting lug unit 43 and the 4th lifting lug unit 44
Interlock with two groups of lifting lugs 4 on top boom 1 in the extending direction position of chord member.
Lifting lug unit includes a pair of otic placode parallel to each other and the connecting rod that is vertically connected between otic placode.
It is welded between connecting rod and otic placode using penetration.
It should be understood by those skilled in the art that the present utility model is not limited to the above embodiments, above-described embodiment and
Only illustrate the principles of the present invention described in specification, on the premise of not departing from the spirit and scope of the utility model,
The utility model also has various changes and improvements, these changes and improvements both fall within the scope of the claimed invention
It is interior.The protection scope of the present invention is defined by the appended claims and their equivalents.
