Description
Technical field
The utility model relates to a kind of crane girder, particularly a kind of crane combination formula girder.
Background technology
Hoisting crane has a wide range of applications at mechanical field, and crane girder is the core component bearing operation pressure, its structure directly affects the serviceability of hoisting crane, in recent years, along with development and the adjustment of Crane Industry, hoisting crane series of products are just towards modularization, modularization and standardized future development, existing crane girder in use, can because stressed reason that is excessive or long-term work be disturbed under producing, and be difficult to repair, the crane girder of open work is because can there is corrosion at some positions in the reason of rainwater, and then affect the structural safety of girder.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of crane combination formula girder is provided, this girder can rapid-assembling, in use finds that the problem such as structural distortion or corrosion also can be changed in time, ensure that the safety that crane girder uses.
The purpose of this utility model is achieved in that a kind of crane combination formula girder, it comprises top board, the down either side of described top board is connected to web, described web forms by multiple web unit is end to end, one end of described web unit is provided with connecting panel A, the other end of described web unit is provided with connecting panel B, and described connecting panel A and connecting panel B all has bolt hole, and described web unit is provided with ribbed stiffener in junction.
The connection mode of described web unit is that bolt connects.
The length 5-10 millimeter larger than the length of connecting panel B of the connecting panel A of described web unit.
The connecting panel A of described web unit is identical with the thickness of connecting panel B.
The connecting panel A of described web unit and the thickness sum of connecting panel B 5-10 millimeter larger than the thickness of web unit.
Connection mode between described top board and web, web plate and back plate is welding.
The beneficial effects of the utility model: by technical scheme described in the utility model, the web of crane girder can have multiple web unit to assemble, the intensity of web unit junction is not less than web cell body, the strengthening rib arranged in junction also can ensure the integral rigidity of crane girder, in use be convenient to install, check and replace, actv. ensure that safety and the economy of crane girder.
