Description
Technical field
This utility model relates to Bridge Erector and the main longitudinal grider of gantry crane use, particularly a kind of rectangle honeycomb fashion main longitudinal grider.
Background technology
Longeron is the capital equipment (parts) of Bridge Erector and gantry crane.Existing Bridge Erector and gantry crane main longitudinal grider generally reality abdomen or girder frame structure, weight is big, wind area is big, construction instability, work high above the ground is dangerous, though girder truss has alleviated than solid web girder weight, wind area is little, but aspect of performance rigidity fails to improve, and globality has declined, construct dangerous, quality can not get being effectively ensured, and on the premise of intensity reaches requirement, beam body width is big simultaneously, is difficult to install and use in some narrow spaces, therefore, the improvement of main longitudinal grider and innovate imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of rectangle honeycomb fashion main longitudinal grider, can effectively solve main longitudinal grider poor rigidity and the problem of operation in narrow space difficulty.
The technical scheme that this utility model solves is, a kind of rectangle honeycomb fashion main longitudinal grider, including beam body, beam body is by the web being vertically arranged of both sides, the integrative-structure of the rectangular in cross-section that the upper cover plate being horizontally mounted at described web upper end and the lower cover being horizontally mounted at described web lower end are constituted, the internal edge of beam body is long to being arranged at intervals with upper cover plate, web, the internal partition that lower cover is linked together, it is vertically arranged with the first reinforcement along beam body inside upper cover plate, it is vertically arranged with the second reinforcement along beam body inside web, it is vertically arranged with the 3rd reinforcement along beam body inside lower cover, track it is provided with on upper cover plate.
This utility model novel structure is unique, and advantages of simple easily produces, low cost, and volume is little, easy to install, safe and reliable, substantially increases the overall performance of Bridge Erector, easy to use, effective, has good Social and economic benef@.

Fig. 2 is that the A-A of this utility model Fig. 1 is to sectional view.
Fig. 3 is that the B-B of this utility model Fig. 1 is to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Be given by Fig. 1-3, this utility model includes beam body, beam body is by the web 6 being vertically arranged of both sides, the integrative-structure of the rectangular in cross-section that the upper cover plate 2 being horizontally mounted at described web upper end and the lower cover 8 being horizontally mounted at described web lower end are constituted, the internal edge of beam body is long to being arranged at intervals with upper cover plate, web, the internal partition 7 that lower cover is linked together, it is vertically arranged with the first reinforcement 3 along beam body inside upper cover plate 2, it is vertically arranged with the second reinforcement 4 along beam body inside web 6, it is vertically arranged with the 3rd reinforcement 5 along beam body inside lower cover 8, track 1 it is provided with on upper cover plate 2.
For ensureing using effect, inside and outside through honeycomb hole 16 is had on described web 6, two pleurosternal honeycomb hole quantity are equal and one_to_one corresponding, on web, seam stiffening plate 17 it is provided with between homonymy honeycomb hole two-by-two, honeycomb hole makes windward side, beam body side little, wind resistance is strong, and seam stiffening plate can guarantee that the intensity of beam body；
There is through hole 7a at described internal partition 7 center；
One end of described web is provided with public central layer 13, and the other end is provided with the body core plate 10 corresponding with public central layer 13.
Equipped with public central layer reinforcing plate 14 on described public central layer 13, improve integral rigidity and section modulus；
Body core plate cover plate 11 and body core plate muscle plate 12 it is provided with on described body core plate 10, improve integral rigidity and section modulus, equipped with string attachment pegs 15a, 15b on body core plate 10, time assembled, the public central layer 13 of beam body end is the most right with body core plate 10 two-by-two, then linked together by string attachment pegs 15a, 15b, it is possible to complete the assembly of beam body two-by-two；
Web outside is stretched out at the two ends, left and right of described lower cover 8, equipped with change gear track 9 on the lower cover of extension.
The whole section of this utility model main longitudinal grider is to have honeycomb hole on rectangle, web and internal partition, so that the rectangular cellular structure of whole main longitudinal grider, its material is made up of shaped steel and steel plate.Its two web can be cut open along set broken line by certain thick steel plate, and then dislocation is welded to each other and forms.First reinforcement of upper cover plate can be welded by 1/2 I-steel, its length direction arranges internal partition at regular intervals, the four of rectangle faces are bound up, common stress, strengthen stiffness and prevent web unstability, additionally equipped with the 3rd reinforcement on lower cover, inside web, it is provided with the second reinforcement, more improves integral rigidity and section modulus.
During installation, often set a roof beam in place and between beam, public central layer, to body core plate, is then linked together by string attachment pegs, completes the assembling of whole main longitudinal grider, the hanging beam trolley travelling limit in orbit on Bridge Erector.
This utility model is compared with existing Bridge Erector main longitudinal grider, there is clear advantage and good effect, from heavy and light, steel 20-30% can be saved, bearing capacity is big, rigidity and section modulus improve 20-25%, section is rectangle, in the case of intensity inconvenience, greatly reducing the width in beam body cross section, the space content narrow at some is easily installed and used, and the honeycombed hole of both sides is the most attractive in appearance but also is easy to install pipeline and cable, what is more important greatly reduces wind area, adds the safety of work high above the ground.Joint uses bearing pin to connect without exception, dismounts the most simple and efficient, adapts to the feature of Bridge Erector mobility, dismounting and freight nearly 40% can be saved, though this utility model has increased slightly with girder truss contrast weight, but rigidity improves 40%, and globality is also greatly improved with safety.This utility model is the component that a suitability is the strongest, also can apply with on other equipment, and such as gantry crane crossbeam etc., its popularization and application must make creative contribution for bridge formation construction.
