Description
Technical field
The present invention relates to a kind of snap joint that box-beam steel structure module connects that is used for, this snap joint can be widely used in makes all kinds of case beams, connects as sections or the assembly unit of the speed of the piece between the block formula box-beam steel structure spare in the large-scale engineering machinery agent structures such as all kinds of bridge formation machines, wind-driven generator installation loop wheel machine.
Background technology
In all kinds of large-scale engineering machineries, for example build bridge machine, rubber-tyred swing arm loop wheel machine and the type hydraulic suspension power flat bed transport vehicle of growing up or the like, because its structure is huge, be not suitable on highway, travelling, and it is on-the-spot to using through long-distance automotive to need to disintegrate, re-assembly, just the main structure with them is divided into several separate assembling and delivery unit (module), connects with removable joint between the module again.For the problem of common used joint is described, existing spy is an example with the dismantled and assembled and X-shaped beam splice of the end bassinet structure of a certain self-propelled swing arm loop wheel machine, it belongs to steel case beam flanged plate bolt joint, its sectional dimension is high 2.64m, wide 2.075m, a circle couples together with bolt and the other side all around, and is as Fig. 1, shown in Figure 2.
Be exactly usually used flanged plate tension bolt connection mode shown in this figure, be called for short flange socket.If this joint is used for the connection that wind-powered electricity generation is installed bassinet structure at the bottom of the special-purpose loop wheel machine, because build is huge, bolt quantity is big, and the construction of assembly group is relatively more difficult, wastes time and energy, and will have a strong impact on the assembled on site work efficiency of loop wheel machine.Thereby also just prolonged the installation period of wind-powered electricity generation unit and dropped into the generating production cycle, so may incur loss through delay the chance of utilizing and bringing into play the wind-force optimum season.
Summary of the invention
Purpose of the present invention provides a kind of snap joint that box-beam steel structure module connects that is used for just at existing weak point in the above-mentioned prior art.Snap joint of the present invention can overcome whole shortcomings of used flanged plate joint in the prior art, and can be applied to other large-scale general self-propelled wheel-mounted crane.
Purpose of the present invention can realize by following technique measures:
The snap joint that is used for the box-beam steel structure module connection of the present invention comprises more piece or the polylith box-beam steel structure module of forming case beam class A of geometric unitA, mutual butt end at per two adjacent box-beam steel structure modules is symmetrically arranged with the quick-assembling joint, described quick-assembling joint comprise the closed flange connecting box up and down that is arranged on each box-beam steel structure module butt end and several be used for installing shear-pin hold concurrently the shearing resistance of alignment pin hold concurrently dowel hole, be arranged side by side the some stud bolt hole pipes that are used to install studs at each closed flange connecting box.And per two stud bolt hole pipe, the shearing resistances that relatively the are provided with dowel hole of holding concurrently all is provided with in coaxial mode.Make studs bear the pressure that is produced by moment of flexure, closed flange case is born the pressure that is produced by moment of flexure, and the shear-pin alignment pin of holding concurrently is born the shearing that is produced by vertical load and played positioning action when installing.
Described up and down closed flange connecting box all be by case beam cover plate, the case web of corresponding position and be arranged on riser, level board, forward flange plate, rear flange plate between the per two adjacent stud bolt hole pipes, the stud bolt hole pipe that is used to install studs is welded mutually is an enclosed flange connecting box; Before and after being inserted into respectively, the two ends of described stud bolt hole pipe are welded mutually in the plate hole of flanged plate.
Described shearing resistance hold concurrently dowel hole by two pin-and-holes about on the rear flange plate that is arranged on closed flange connecting box and be arranged on the rear flange plate rear flange plate of lower seal enclosed flange connecting box about two pin-and-holes constitute.
Box-beam steel structure module described in the present invention is the in-line structure, is provided with the quick-assembling joint in two butt end.
Box-beam steel structure module described in the present invention is a decussate texture, is provided with the quick-assembling joint in its four butt ends.
Box-beam steel structure module described in the present invention is provided with the manhole for staff's turnover.
The present invention has following beneficial effect compared with prior art:
1) simple structure, securing member quantity reduces 10 times more than, and its most direct effect is: fast convenient! This when wind-powered electricity generation is installed special-purpose loop wheel machine assembled on site just by the great index of strong request of users and concern.
2) each parts of joint are stressed simple and direct, clear and definite, reliable, and studs is born the pulling force that is produced by moment of flexure, and flange connecting box casing is born the pressure that moment of flexure produces, and shear-pin is born the shearing that is produced by vertical load.Replace the flanged plate of bulk with small-sized flange case, replaced the bolt group of big coverage rate with several studs.
3) coupling stiffness of joint is greatly improved, and makes structure approach zero by the geometry deformation that jointing caused.The lifting precision and the work efficiency of wind-powered electricity generation unit can directly be improved in car rigidity higher position, the end.
