Description
Technical field
The utility model relates to a kind of Bailey truss combined gantry crane, particularly a kind of Bailey truss combined gantry crane superelevation steel leg.
Background technology
Highway in China, railway, urban construction are in a high-speed developing period, in building highway, railway, inter-city rail transit, city overhead road building site, there are many precast concrete T-beams, case beam to need handling, set up, and building site belongs to temporary building, after completing, project needs transition migration.Therefore, construction user wish hanging beam hoisting crane can dismounting, convenient transportation, be easy to control operation, and can become according to the various combination that plays weight the hoisting crane of different hoisting capacities, different span, different lifting altitudes.
Since last century the eighties, fast development along with China's economic construction, unit in charge of construction starts to adopt Bailey truss to be assembled into various force structures or the elevator machineries such as transfer crane, Bridge Erector, but be confined to simple type, hoisting capacity is little, fail to form product line, also Shortcomings aspect safety performance.Some building site affects because of execution conditions, and weight sling height reaches more than 30 meters, needs super-high transfer crane.
For the problems referred to above, the design people has designed a kind of Bailey truss combined gantry crane superelevation steel leg, thereby increases the sling height of hoisting crane, and easy accessibility, is convenient to transportation, adapts to multiple user's needs.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Bailey truss combined gantry crane superelevation steel leg
The utility model solves the technical scheme that its technical matters adopts:
Bailey truss combined gantry crane superelevation steel leg, is characterized in that: comprise truss upright-column and the support together with truss upright-column separable joint, truss upright-column consists of some truss element stacks, and the height changeable of its stack
,between two neighbouring truss elements, by truss finger setting, connect, between the adjacent and truss element side by side in two left and right, by truss bolt, connect, between the adjacent and mutual rectangular truss element in two left and right, by angle brace and chord bolt, connect, described support comprises rack body and the connection box being bolted with rack body, and described truss upright-column is connected with connection box by connecting pin.
Described truss upright-column becomes the steel structure combination form of A font structure with support welding.
Described framework is bolted and is formed by steel pipe.
The tail end of described truss pin is provided with a pin-and-hole, in this connecting bore, is inserted with spring cotter.
Between described support and truss upright-column, be provided with digonal link.
