Description
Technical field
The utility model relates to a kind of quarry tippers, specifically, are related to a kind of front axle of mining dump truck structure.
Background technique
Off-highway quarry tipper is the prevailing traffic equipment of large surface mine, and its structure is complicated, working environment is severe.
Front axle of mining dump truck as the important component in entire mine car running gear, the superiority and inferiority of structural behaviour to it is mining from
The operation and maintenance unloaded has important influence.
As shown in Figure 1, being front-axle structure schematic diagram in the prior art；As shown in Fig. 2, be in the prior art A-A to cut open
Face schematic diagram.
Front-axle structure is integrally in " recessed " shape, mainly by body of a bridge welding girder, outstanding cylinder support, tie rod support, longitudinal tie branch
Seat composition.Wherein body of a bridge welding girder is welded by upper plate 1, lower plate 2, two blocks of front and back web 3 and welding liner plate 4.
It is connected between upper plate 1, lower plate 2 by two blocks of front and back web 3, upper plate 1 passes through with two blocks of front and back web 3
Welding liner plate 4 welds together, and lower plate 2 is welded together with two blocks of front and back web 3 by welding filler strip 5.Web 3 is at turning
Transition position has out the slot of certain length, is welded together by sealing weld and welding liner plate 4, these are provided to reinforce original knot
The intensity of structure corner, and reality can not still make up stress concentration phenomenon caused by its own structure.
Existing front axle of mining dump truck all uses whole square-box-shaped welded-steel plate construction, and both ends are in the small bend angle transition of " Z " type
There is stress concentration at small bend angle in use, so structural-load-carrying capacity is not strong, weld seam be easy to cause to open in structure, this structure
Phenomena such as splitting.And as market of the off-highway quarry tipper to more large-tonnage vehicle needs, so that front-axle structure intensity at present
Problem more highlights, and has been unable to meet the requirement of vehicle safety reliability service.
Utility model content
The technical issues of the utility model is solved is to provide a kind of front axle of mining dump truck structure, so that the carrying of structure
Ability is significantly promoted, and service life lengthens significantly.
Technical solution is as follows:
A kind of front axle of mining dump truck structure, including the body of a bridge weld girder, the body of a bridge welding girder include: arc upper plate,
Arc lower plate, arc-shaped webs are connected between arc upper plate, arc lower plate by two pieces of arc-shaped webs, link position
It is connected with welding filler strip；Body of a bridge welding girder is integrally in the smooth transition of dome-shaped orthodrome, and arc upper plate, arc lower plate exist
Bending position is excessive using arc, and the top and bottom of arc-shaped webs are arc-shaped side.
Further, arc upper plate, arc lower plate, arc-shaped webs form body structure, inside four by welding manner
Angle is overlapped using welding filler strip.
Further, arc upper plate, arc lower plate by monolith steel plate rolling be dome-shaped, the top of arc-shaped webs and
Bottom is arc-shaped side, and the shape of arc-shaped side and arc upper plate, arc lower plate is adapted.
The utility model technical effect includes:
The utility model is in the case where guaranteeing the not increased situation of front-axle structure own wt, by the change of structure type and excellent
Change, 20% or more bridge stress intensity before increasing.It eliminates and adds at the reinforcement liner plate and its small round corner of the inside configuration of original preceding bridge
The liner plate of weldering to simplify structure, while is more uniformly stressed entire preceding bridge, and structural strength is big, long service life.
1. front axle of mining dump truck body of a bridge structure is changed to as dome-shaped by the utility model, so that structural-load-carrying capacity is substantially
The promotion of degree, service life lengthen significantly.
2. the utility model, which is jumped out, reinforced the usual think of of front axle of mining dump truck intensity by increasing thickened material in the past
Road does not increase body of a bridge own wt using the modes such as reinforcing rib are welded with, and while so that structure is simpler, also increases whole
The fuel-economy type of load capacity and the vehicle operation of vehicle.
3. the utility model after structure optimization, has simplified no longer necessary reinforcement liner plate reinforcing rib etc., reduces and add
Work technique process, thus reduce production cost.
4. the utility model is applicable not only to quarry tipper field, it could be applicable to other heavy and engineering trucks, make
It is very extensive with range.
Detailed description of the invention
Fig. 1 is front-axle structure schematic diagram in the prior art；
Fig. 2 be in the prior art A-A to diagrammatic cross-section；
Fig. 3 is the schematic diagram of quarry tipper front-axle structure in the utility model；
Fig. 4 is the diagrammatic cross-section of quarry tipper front-axle structure B-B direction in the utility model.
Specific embodiment
The specific embodiment for fully showing the utility model is described below, to enable those skilled in the art to reality
It tramples and reproduces.
The utility model changes existing " recessed " the shape structure of the front axle of mining dump truck body of a bridge in the prior art, creative
It is proposed new domes, the arch body of a bridge is moulded smooth, without the singular point in stress, so that stress is uniformly divided on the body of a bridge
Cloth has greatly reinforced preceding bridge itself by loading capability.Meanwhile it being further simplified due to the not enough reinforcing line to be welded with of intensity before
The components such as plate, so that structure and manufacturing procedure are simpler.
As shown in figure 3, being the schematic diagram of quarry tipper front-axle structure in the utility model；If Fig. 4 is the utility model
The diagrammatic cross-section of middle quarry tipper front-axle structure B-B direction；
The structure that its body of a bridge of front axle of mining dump truck structure welds girder includes: arc upper plate 6, arc lower plate 7, arc
Shape web 8 is connected between arc upper plate 6, arc lower plate 7 by two pieces of arc-shaped webs 8.Under arc upper plate 6, arc
Bottom plate 7, arc-shaped webs 8 form body structure by welding manner, and internal quadrangle is overlapped using welding filler strip 9.Body of a bridge weldering
Connecing girder integrally is in the smooth transition of dome-shaped orthodrome, and arc upper plate 6, arc lower plate 7 use arc mistake in bending position
Degree, the top and bottom of arc-shaped webs 8 are arc-shaped side, and arcuate structure disperses stress more, solves and exist in the prior art
The defects of stress collection of each corner is welded with liner plate without itself aperture of web 3 and inside.
Arc upper plate 6, arc lower plate 7 are dome-shaped, the top and bottom of arc-shaped webs 8 by the rolling of monolith steel plate
For arc-shaped side, the shape of arc-shaped side and arc upper plate 6, arc lower plate 7 is adapted.
It should be understood that above description be only it is exemplary and explanatory, the utility model, this reality can not be limited
With the novel structure for being not limited to be described above and be shown in the accompanying drawings, and can carry out without departing from the scope it is each
Kind modifications and changes.The scope of the utility model is only limited by the accompanying claims.
