Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that gantry beam root on a kind of quarry tipper Portion's stiffener, has the advantages that transition of stress is mild, load is reasonably distributed, intensity is high.
For solving prior art problem, the utility model discloses gantry beam root on a kind of quarry tipper and strengthen structure Part, arranges an anterior triangle box-type member on front side of upper gantry beam root, and rear side arranges a rear portion triangle box structure Part, makes gantry beam longitudinal section overall in up-narrow and down-wide form, and the bottom of two triangle box-type members is used for longitudinal beam connected.
Preferably, anterior triangle box-type member includes the front extension of gantry beam girth sheets, front pasting board and front vertical plate;Rear portion Triangle box-type member includes extension after gantry beam girth sheets, rear pasting board and back vertical plate;The upper front extension of gantry beam girth sheets with Front vertical plate be arranged in parallel, and arranges front pasting board in the middle of it;After upper gantry beam girth sheets, extension be arranged in parallel with back vertical plate, and wherein Between rear pasting board is set.
Preferably, front pasting board and rear pasting board entirety are the tiles structure with arc bus, and this structure ensures that welding connects Stress gentle transition at Tou, also can increase fusion length, improves solder design intensity.
Preferably, the two ends of front pasting board and rear pasting board are tongue shape or swallowtail-shaped structure.
Preferably, after the upper front extension of gantry beam girth sheets, front vertical plate, upper gantry beam girth sheets, extension and back vertical plate are three Dihedral reinforcing plate structure, its hypotenuse is arc.
Preferably, front vertical plate is arranged on the outside of the front extension of gantry beam girth sheets, and back vertical plate is arranged on gantry beam circle The outside of extension after plate.
This utility model has the advantages that gantry beam and longeron junction are orthodrome transition, and STRESS VARIATION is put down Slow, reduce stress and concentrate, meanwhile, upper gantry beam longitudinal section is overall in up-narrow and down-wide form, meets cantilever beam up-narrow and down-wide Feature, reasonable stress, intensity is high.

Reference:
Pasting board before 1;2 front vertical plates;Pasting board after 3;4 back vertical plates;Gantry beam on 5;The front extension of 5-1 upper gantry beam girth sheets;5-2 Front web;Extension after 5-3 upper gantry beam girth sheets;6 longerons;6-1 longeron upper cover plate.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
If Fig. 3 is to shown in 6, gantry beam root stiffener on a kind of quarry tipper, cloth on front side of upper gantry beam 5 root Putting an anterior triangle box-type member, rear side arranges a rear portion triangle box-type member, makes gantry beam 5 longitudinal section overall In up-narrow and down-wide form, the bottom of two triangle box-type members is used for longitudinal beam connected 6.
Anterior triangle box-type member includes gantry beam girth sheets front extension 5-1, front pasting board 1 and front vertical plate 2, aforementioned three The bottom of individual parts is connected with the longeron upper cover plate 6-1 on front side of upper gantry beam, rear portion connects with front web 5-2 of upper gantry beam Connect;Being similar to, rear portion triangle box-type member includes extension 5-3 after gantry beam girth sheets, rear pasting board 3 and back vertical plate 4, aforementioned The bottom of three parts is connected with the longeron upper cover plate 6-1 on rear side of upper gantry beam, rear portion (does not shows with the rear web of upper gantry beam Go out) connect.Upper gantry beam girth sheets front extension 5-1 be arranged in parallel with front vertical plate 2, and arranges front pasting board 1 in the middle of it;Upper gantry beam After girth sheets, extension 5-3 be arranged in parallel with back vertical plate 4, and arranges rear pasting board 3 in the middle of it.Front vertical plate 2 is arranged on gantry beam circle The outside of plate front extension 5-1, back vertical plate 4 is arranged on the outside of extension 5-3 after gantry beam girth sheets.
Front pasting board 1 and rear pasting board 3 entirety are the tiles structure with arc bus, and this structure ensures should at welding point Power gentle transition, also can increase fusion length, improves solder design intensity.
The two ends of front pasting board 1 and rear pasting board 3 are tongue shape or swallowtail-shaped structure.
After upper gantry beam girth sheets front extension 5-1, front vertical plate 2, upper gantry beam girth sheets, extension 5-3 and back vertical plate 4 are Triangle reinforcing plate structure, its hypotenuse is arc, and making longeron 6 is Rouno Cormer Pregrinding Wheel structure with the junction of upper gantry beam 5, compared to directly Angle transition, is greatly lowered stress mutation, reduces the generation of fatigue crack.
In this utility model, the connected mode of all parts is welding.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and deformation, these change Enter and deform and also should be regarded as protection domain of the present utility model.
