Abstract

A hole-girder type box gear crane comprises a frame system and four tower-shaped supporting legs. Each of the four tower-shaped supporting legs is connected with a running gear. The frame system has two girders and four beams, the tops of the four tower-shaped supporting legs are connected with two girders and two beams, and the two girders are connected through two beams. The frame system and tower-shaped supporting legs are provided with distributed air through holes. The circumferences of the air through holes are provided with reinforcing rings, and the girders are connected with a lifting device. The hole-girder type box girder crane has the advantages of adopting a double girder box type structure, guaranteeing enough strength to lift 900 tons of box girders, adding air through holes with reinforcing rings on girders, beams and supporting legs, thereby greatly reducing the wind load of the whole machine and effectively reducing the weight of the whole machine. Moreover, the supporting legs are tower-shaped box type structures, thereby enabling the whole machine to have high strength and high reliability.

Description

Hole beam type case beam hoisting crane
Technical field
The utility model relates to a kind of tackling system, particularly a kind of hole beam type case beam hoisting crane.
Background technology
Hoisting crane is the modern industry imperative equipment.Modern hoisting crane majority is truss structure or is case type closed structure that these two kinds of structural shape hoisting cranes all have merits and faults separately.
1, truss-like hoisting crane: truss structure is its keystone configuration.Truss-like hoisting crane majority is used for outdoor sports ground to be used, and its wind resistance resistance is little, and working stability be outdoor first-selection, but the truss-like hoisting crane requires to have bigger installing space, and when the lifting tonnage was big, its texture ratio was than bulky complex.
2, box-shaped enclosed construction hoisting crane: the sealing box-shaped is a keystone configuration.Advantages such as box-shaped enclosed construction hoisting crane majority is used for indoor use, and it has compact conformation, and the lifting tonnage is big.The most sealing box-shapeds that adopt of box type construction have bigger wind area, generally are not suitable for outdoor sports ground and use.When the lifting tonnage is bigger, in the time of must being used for outdoor construction again, it is heavy that its structure also becomes relatively, and its manufacturing cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of: can bear than strong wind and carry, the hole beam type case beam hoisting crane of good operating stability.
The purpose of this utility model is achieved in that this hoisting crane includes machine frame system and turriform supporting leg, and the turriform supporting leg has four, all is connected with running gear in the bottom of each supporting leg; Machine frame system is two girders, and crossbeam is four, is connected with two girders and two crossbeams at four turriform supporting leg Xiang Duan, also is connected with two crossbeams between two girders; With the turriform supporting leg wind hole was arranged on machine frame system, the wind pore size distribution has reinforcing pad in mistake border, wind hole on machine frame system and turriform supporting leg excessively; On girder, be connected with lifting appliance.
Beneficial effect owing to adopted such scheme, had the machine frame system and the turriform supporting leg in wind hole, can alleviate complete machine weight, bore than strong wind and carried, the complete machine good operating stability; Machine frame system has girder and crossbeam, and girder is two girders, links into an integrated entity by four crossbeams between two girders, and two girders drop on the crossbeam assembly, have constituted a box main beam structure like this; Cross the wind pore size distribution on box girder and turriform supporting leg, and have reinforcing pad, it is cellular that whole rack construction seems again, can effectively alleviate complete machine weight, reduces winds aloft and carry.Can bear than strong wind and carry, good operating stability has reached the purpose of this utility model.
Advantage: this hoisting crane has the High-Performance Hoist of large-tonnage hoisting capacity, adopt two girder box-structures, 900 tons of sufficient intensities that the case beam is required are mentioned in assurance, set up respectively on girder, crossbeam, the supporting leg have a reinforcing pad cross the wind hole, the wind that makes complete machine bear carries and reduces greatly and actv. has alleviated the weight of complete machine; Supporting leg is the turriform box-structure, and the intensity height of complete machine has advantages of higher stability.Adopt high strength bolt to connect between the supporting leg of hoisting crane, can change the supporting leg sections of different length according to need of work, thereby change hoisting depth neatly, thereby be applicable to the work place of multiple different operating modes.
Structural shape novelty, hole beam type box-structure have complete machine from heavy and light, and the handling tonnage is big, lifting when being applicable to high speed railway construction, use during the tote box beam.It can bear than strong wind and carry, good operating stability, the cost performance height.
Description of drawings
Fig. 1 is the utility model constructional drawing.
Fig. 2 is the side-looking constructional drawing of Fig. 1.
Among the figure, 1, machine frame system; 2, turriform supporting leg; 3, running gear; 4, lifting appliance.
The specific embodiment
Embodiment 1: this hoisting crane includes machine frame system 1 and turriform supporting leg 2, and turriform supporting leg 2 has four, all is connected with running gear 3 in the bottom of each supporting leg; Machine frame system 1 is two girders, and crossbeam is four, is connected with two girders and two crossbeams at 2 ends of four turriform supporting legs, also is connected with two crossbeams between two girders; With turriform supporting leg 2 the wind hole was arranged on machine frame system 1, the wind pore size distribution has reinforcing pad in mistake border, wind hole on machine frame system 1 and turriform supporting leg 2 excessively; On girder, be connected with lifting appliance 4.
Machine frame system 1 mainly is made up of crossbeam and girder.Each crossbeam is made of by the height bolt connection two sections needle beams, and each girder is made of by the high strength bolt connection four sections little girders.Open the wind hole excessively that has reinforcing pad respectively on crossbeam and girder, seem a kind of cellular, the wind that can reduce all directions greatly carries, and wind resistance is good.Machine frame system keeps the high strength box type construction to reduce the wind resistance area again simultaneously, can be suitable for outdoor site construction and have very high intensity.
Whole hoisting crane is supported by four turriform supporting legs 2, and each supporting leg is divided into three sections, is respectively down supporting leg, middle supporting leg, upper supporting leg.Narrow on middle supporting leg and the following supporting leg bottom width, vertical cross-section is trapezoidal, and the horizontal section is a square.Whole four turriform supporting legs 2 form four " pin ", and four pin are fixed on the running gear 3.Machine frame system 1 can with the upper supporting leg direct connection, also can cancel upper supporting leg, directly be connected with middle supporting leg, perhaps change the upper supporting leg of differing heights.Lifting beam machine can be as required like this, and the automatic compensation hoisting depth satisfies the different work demand.That also opens the band reinforcing pad respectively on upper supporting leg and middle supporting leg crosses the wind hole, can reduce all directions wind greatly and carry, thereby improve the steadiness of complete machine.
