Abstract
The invention discloses an eight-bar portal structure of a portal crane. The eight-bar portal structure of the portal crane comprises a large pinwheel supporting ring, stay bars and a portal, and is characterized in that the portal adopts a rectangular frame structure with stand columns, formed by welding a box type connection beam, a bearing beam, an I-shaped connection beam and a horizontal I-shaped beam, the large pinwheel supporting ring is arranged on the portal through the stay bars, the stay bars are arranged around the portal and the large pinwheel supporting ring in a supporting manner, and upper and lower connectors are fixedly connected with the large pinwheel supporting ring and the portal. Compared with the prior art, the eight-bar portal structure of the portal crane, provided by the invention, has a simple structure, is excellent in integral rigidness, high in reliability, and is particularly light in weight, further lowers the manufacturing cost, and improves the crane using safety.
Description
Technical field
The present invention relates to a kind of gantry crane technical field, especially a kind of large for large gauge, low lifting altitudeEight bar portal-framed structures of type high pedestal jib crane.
Background technology
At present, eight bar portal-framed structures of big-and-middle-sized high pedestal jib crane extensive use, the bottom gate seat supporting of this structure is horizontalBeam, for ensureing that enough rigidity generally all adopt the portal-framed structure form of intersecting, its top strut adopts box beam structure.
The portal-framed structure power transmission weak effect of prior art, manufacturing process complexity, production cost is high, especially the case of top strutType girder construction, its sectional dimension is relatively little, and the process of manufacture, for the suitable trouble of the soldering of middle diaphragm plate, is manufacturedAll cumbersome with Welding Testing, quality cannot be effectively controlled and ensure, have a strong impact on crane safety in utilization andEconomy.
Summary of the invention
The object of the invention is eight bar door frame knots of a kind of high pedestal jib crane designing for the deficiencies in the prior artStructure, adopts the lower gate holder structure of circular strut and box bearing cross beam and I shape straining beam composition, crane upper load byCircular strut is delivered to lower gate holder structure, then is delivered to ground by lower gate holder structure by traveling mechanism of the larger traveller, lower gateThe carrier bar of holder structure adopts large box type plate beam structure, and the size of cross sectional shape and thickness of slab and its stressed being directly proportional, make material energyAccess and make full use of, have lightweight, easily manufacturedly, stock utilization is high, and especially pipe strut has and draws materials conveniently, manufacturesSimply, little, the welding of wind factor to its structure influence the little and each direction of the moment of inertia equate and the technology of low cost of manufacture excellentPoint.
The object of the present invention is achieved like this: a kind of eight bar portal-framed structures of high pedestal jib crane, comprise that large pinwheel props upCarrier ring, strut and gate seat, be characterized in that gate seat contacts beam, carrier bar, I shape contact beam and horizontal i-shaped beams by box and weldsBe connected into the rectangular frame structure that is provided with column, large pinwheel support ring is arranged on gate seat by strut, and described strut props up with triangleSupport is arranged on four sides of gate seat and large pinwheel support ring, and is fixedly connected with gate seat with large pinwheel support ring by upper and lower joint.
The long limit of rectangular frame structure of described gate seat is fixedly connected with column by box contact beam, and its minor face is joined by I shapeThe truss of binder composition is fixedly connected with column, and rectangular frame is provided with and contacts beam with two boxes and be fixedly connected with " work " fontCarrier bar and horizontal i-shaped beams arranged in a crossed manner, horizontal i-shaped beams by fishplate bar and box contact beam, horizontal i-shaped beams andCarrier bar is fixedly connected with.
Described gate seat bottom adopts bell-mouth structure of air.
The present invention compared with prior art has simple in structure, and just, manufacturing process is simple for power transmission effect and entirety, reliableProperty high, especially lightweight, low cost of manufacture, has improved security and economy that crane uses greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is lower gate holder structure schematic diagram;
Fig. 3 is that the A of Fig. 2 is to view.
Detailed description of the invention
Consult accompanying drawing 1, the present invention is made up of large pinwheel support ring 1, strut 3 and gate seat 4, and described gate seat 4 is contacted by boxBeam 6, carrier bar 7, I shape contact beam 9 and horizontal i-shaped beams 10 are welded into the rectangular frame structure that is provided with column 5, large pinwheelSupport ring 1 is arranged on gate seat 11 by 3 of struts; Described strut 3 is arranged on gate seat 4 and large pinwheel support ring with triangular support1 four sides, and be fixedly connected with gate seat 4 with large pinwheel support ring 1 by upper and lower joint 2; Described gate seat 4 bottoms adopt horn mouthStructure 11.
Consult accompanying drawing 2～accompanying drawing 3, the long limit of rectangular frame structure of described gate seat 4 is fixing with column 5 by box contact beam 6Connect, the truss that its minor face is made up of I shape contact beam 9 is fixedly connected with column 5, and rectangular frame is provided with and two box connectionThe carrier bar 7 that binder 6 is fixedly connected with " work " font and horizontal i-shaped beams 10 arranged in a crossed manner, horizontal i-shaped beams 10 is by connecingPlate 8 contacts beam 6, horizontal i-shaped beams 10 and carrier bar 7 with box and is fixedly connected with.
The present invention makes like this and work: the strut 3 of large pinwheel support ring 1 four sides is with the structure of triangular support,Its triangle top is welded by upper binding head 2 and large pinwheel support ring 1, and triangle two base angles are respectively by lower union joint 2 and gate seat 4Box contact beam 6 and I shape contact beam 9 weld. In order to alleviate the weight of gate seat 4, the contact beam of both sides adopts I shape contactThe truss structure that beam 9 forms, this lightweight construction, easily manufactured, mainly play the connection of fixing gate seat 4 substructures and increase by eightThe integral rigidity of bar door frame, both can alleviate weight, can play again the effect of connection. Large pinwheel support ring 1 is carried with topLotus is delivered to the I shape articulated beam 9 of bottom gate seat 4 by eight struts 3, strut 3 is delivered to upper load the gate seat of bottomOn 4 box contact beam 6 and I shape contact beam 9, bear gantry crane upper load, and keep its stability, its topThe load of structure passes to holding of gate seat 4 pass to the strut 3 of positive strut 3 and side by large pinwheel support ring 1 after againCarry beam 7, by the general frame structure of gate seat 4, superstructure load is delivered to ground by traveling mechanism of the larger traveller.
More than just the present invention is further illustrated, and not in order to limit this patent, all is the present invention's equivalence enforcement,Within all should being contained in the claim scope of this patent.
