Abstract
The utility model relates to a large span truss-string gantry crane, which comprises a beam-trussed upper beam, a hoisting trolley, a space beam-trussed supporting leg, an operating crane and is characterized in that an arc chord stay is arranged under the beam-trussed upper beam, two ends of the arc chord stay are connected with two sides of the beam-trussed upper beam, the lower portion of the beam-truss upper beam is provided with a plurality of supporting bars which are connected with the arc chord stay. The utility model has the advantages that the internal force distribution in the gantry girder can be allocated through utilizing sinking truss-string chord, thereby achieving the purpose of reducing dead weight and meanwhile being convenient to assemble and disassemble the large span truss-string gantry crane.
Description
Technical field
The utility model relates to a kind of gauntry crane, and particularly a kind of large span is opened string formula gauntry crane.
Background technology
At present in field, large-scale station in logistics such as train, the vehicular transport handling yard, a large amount of gauntrys crane becomes important tool in the handling equipment, along with the progressive gauntry crane of society towards maximize, the large span development, and the deadweight of traditional beam type and purlin formula gauntry crane sharply increases along with the increase of span and hoisting capacity, thereby has increased manufacturing cost and the installation difficulty of self.
Summary of the invention
The purpose of this utility model is to solve in the prior art in the large-scale loading-unload station field in the logistics such as train, the vehicular transport handling yard, a large amount of gauntrys crane becomes important tool in the handling equipment, along with the progressive gauntry crane of society towards maximize, the large span development, and the deadweight of traditional beam type and truss-like gauntry crane sharply increases along with the increase of span and hoisting capacity, thereby has increased the problem of manufacturing cost and the installation difficulty of self.The utility model design large span is opened string formula gauntry crane, comprise beam purlin formula wind up beam, crane carriage, beam purlin, space formula supporting leg, operation cart, it is characterized in that: beam purlin formula is winded up has arc string rope under the beam, the wind up both sides of beam of the two ends of arc string rope and beam purlin formula are connected, and the formula beam bottom of winding up in beam purlin has many poles to connect arc string ropes.The utility model has the advantages that the internal force that a string rope that can utilize sunk type is allocated in the gauntry crane crossbeam distributes, to reach the purpose that alleviates deadweight, what can make large span simultaneously opens the mounting or dismounting of string formula gauntry crane conveniently.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise beam purlin formula wind up beam 1, crane carriage 2, beam purlin, space formula supporting leg 3, operation cart 4 among the figure, it is characterized in that: the formula beam that winds up in beam purlin has arc string rope 5 for 1 time, the wind up both sides of beam 1 of the two ends of arc string rope 5 and beam purlin formula are connected, and formula beam 1 bottom of winding up in beam purlin has many poles 6 to connect arc string ropes 5.The maximum bending moment of span centre of opening string formula gauntry crane is to distribute by the beam purlin formula couple that beam 1 pressurized and sunk type string rope 5 produce by pulling force of winding up, this stress system has been given full play to the wind up resistance to tension of beam 1 compression capability and sunk type string rope 5 of beam line, from entire cross section, owing to introduced sunk type string rope 5 and improved the counter-bending modulus in cross section greatly, so this version can be utilized the small construction deadweight and obtain bigger lifting power.
