Abstract
The utility model relates to a fixed or movable bridge or a gantry. The bridge with a four-beam structure comprising two end beams and two main beams adopts a demountable connection method; the junction of each end beam and each main beam is respectively welded with a connecting plate whose middle is respectively provided with a positioning pin and positioning hole; the outer side of the connecting plate is symmetrically provided with high-strength bolts which are connected; thus the bridge with a four-beam structure of a crane is formed. The utility model which has the advantages of simple structure and convenient process and manufacture has favorable popularizing and using foreground for giant cranes.
Description
The utility model relates to fixing or movably crane span structure or portal frame.
Crane bridge generally all adopts the integral solder structure, is about to two end carriages and becomes a frame shape crane span structure with two Main Girder Welding, and the crane span structure of this structure is bulky, and Heavy Weight makes transportation and installs all very inconvenient.Afterwards, also have employing crane span structure to be divided into two in the middle of the end carriage, connect crane span structure but carry out demolition after the installation, but and between end carriage and the girder with demolition bonded assembly four girder construction crane span structures.But these crane span structures will have good location and be connected clamping structure in the junction of girder and end carriage, cause the complex structure of crane span structure junction, and processing difficulties needs a lot of specialized equipments, increases manufacturing cost.
The purpose of this utility model is a kind of girder simple in structure of design and the connection structure of end carriage, and can satisfy the needs that use and install of various crane span structures, is suitable for actual use.
The technical solution of the utility model is respectively to weld the lastblock gusset piece in the junction of girder and end carriage, on the midway location of a gusset piece, fix a locating dowel pin, on the relevant position of another piece gusset piece, be provided with knock hole, two gusset piece pairing processing, setting element during as installation, connection is docked with high strength bolt in the outside at gusset piece, is the high strength bolt connection structure, constitutes a kind of later-model hoisting crane disassembling four girder construction crane span structures.
Accompanying drawing 1 is the connecting bridge structural representation of crane bridge, and Fig. 2 is the birds-eye view of Fig. 1, and Fig. 3 is the A-A cutaway view of Fig. 1, and Fig. 4 is the enlarged drawing of I part among Fig. 1.1 is locating dowel pin among the figure, and 2 is gusset piece, and 3 is end carriage, and 4 is girder, and 5 is high strength bolt.
In conjunction with the accompanying drawings, provide the utility model embodiment.
Present embodiment is a kind of concrete structure of 5 tons of crane bridges.The two ends of girder 4 and being connected with end carriage 3 medial surfaces respectively, and constitute the crane span structure of frame shape four girder constructions by two butt beams 3 and two girders 4, end carriage and girder are welded-steel plate construction, lastblock gusset piece 2 is respectively welded in junction at end carriage 3 and girder 4, and it is reinforced with corresponding reinforced rib, welding can be adopted overlap joint (as shown in the figure), also can adopt butt joint, the middle part of a gusset piece is fixed with a locating dowel pin 1 therein, present embodiment is for burn-oning a large diameter cylinder locating dowel pin 1 on the gusset piece of end carriage, and pairing is processed with a location pin-and-hole on corresponding girder gusset piece, location usefulness when the back splicing is installed is provided with two rows in the bilateral symmetry of gusset piece and connects with high strength bolts 5, uses packing ring, nut docks connection, end carriage and girder are fused, constitute disassembling four girder construction crane span structures.
The utility model portal structure is simple, makes easy to processly, because crane span structure is connected to disassembling, thereby greatly facilitate processing, transportation and installation, and method of attachment is also very easy, and very big application value is particularly arranged on the crane span structure of goliath.
Claims (2)
1, a kind of crane bridge, it is made of the crane span structure of four girder constructions two end carriages and two girders, but end carriage adopts demolition to be connected with girder, it is characterized in that respectively welding the lastblock gusset piece in the junction of end carriage and girder, be respectively equipped with locating dowel pin and knock hole in the centre of gusset piece, be provided with the high strength bolt connection structure in the outside of gusset piece.
2, crane bridge according to claim 1 is characterized in that locating dowel pin is a large diameter cylinder locating dowel pin, and tie bolt is the center with the locating dowel pin, is symmetrical arranged.
