Abstract
The utility model discloses a longitudinal beam structure of a frame of a mine truck. The longitudinal beam structure belongs to the technical field of frame structures and comprises an upper cover plate, two webs and a lower cover plate which are connected into a closed box body structure, wherein the widths of the upper cover plate and the lower cover plate are both larger than the interval at the outer sides of the two webs. The longitudinal beam structure has the beneficial effects that the processing technology is simple, the welding seams are firm, the strength and the durability of the frame can be improved, and the costs of production, use and maintenance are reduced.
Description
Technical field
The utility model relates to a kind of chassis side rail structure, relates in particular to a kind of mine truck chassis side rail structure, belongs to the body frame structure for automotive technical field.
Background technology
Mine truck is the key equipment during the surface mine exploitation is built with extensive cubic metre of earth, is the professional equipment that is used for ore or earth handling, has characteristics such as load-carrying is big, work efficiency height.At present, mine truck has large, hugeization Development Trend, and is corresponding, also more and more harsher to the requirement of the carrying structure intensity of mine truck.The vehicle frame of mine truck is as the matrix of car load, and the load of other each subassembly and goods all is applied on the vehicle frame, therefore requires vehicle frame to have good intensity and reliability.
The vehicle frame of mine truck is made up of a pair of longeron and a plurality of crossbeam, and crossbeam constitutes the enclosed construction of vehicle frame with longeron.Wherein, longeron is the left-right symmetric structure, passes through car load, and its intensity and reliability effect to vehicle frame is very big.As shown in Figure 1; Mine truck of the prior art all adopts box welded structure, and 3 welding become with lower cover by upper cover plate 1, web 2, and characteristics are width that the width of longeron equals cover plate 1; Cover plate 1 all is equipped with groove with web 2, and weld seam fills up groove and is used for welding.This version is simple, but exists processing technology complicated, need carry out leveling behind cover plate 1 and 2 dozens of intact grooves of web, shortcomings such as the more shallow and easy of crack of weld seam.
Summary of the invention
To above-mentioned existing technical matters, the utility model provides a kind of mine truck chassis side rail structure, and processing technology is simple, and weld seam is firm, can improve the intensity and the durability of vehicle frame, reduces the cost of producing, using and keep in repair.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme: a kind of mine truck chassis side rail structure; Comprise upper cover plate, two blocks of webs and lower cover, be interconnected to the osed top body structure, the width of upper cover plate, lower cover is all greater than the spacing of two web outside.
Further, web becomes vertical relation with upper cover plate, lower cover.
Further, the thickness range of upper cover plate and lower cover is 5-200mm.
Further, the thickness range 5-200mm of web.
Further, the spacing range of two web outside is 3-100mm.
Further, the web outside edge has groove.
Further, groove size≤web thickness.
The beneficial effect of the utility model is: 1, do not beat groove on the cover plate up and down, the groove on the web is optional, has significantly reduced to beat behind the groove leveling used man-hour, simplified processing process; 2, weld seam is positioned at the corner that forms between web and upper cover plate, and big and easy retention of weld seam bonded area can improve the intensity and the durability of vehicle frame, and weld seam is firm; 3, the intensity and the durability of vehicle frame have been improved, the cost that has reduced production, uses and keeped in repair.
Description of drawings
Fig. 1 is the structural representation of mining truck frame longeron section in the prior art;
Fig. 2 is the structural representation of the chassis side rail of the utility model;
Fig. 3 is the structural representation of longeron section among the embodiment one;
Fig. 4 is the structural representation of longeron section among the embodiment two.
Among the figure: 1, upper cover plate, 2, web, 3, lower cover.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises upper cover plate 1, two webs 2 and lower covers 3, is interconnected to the osed top body structure, and the width of upper cover plate 1, lower cover 3 is all greater than the spacing in two web 2 outsides.
Wherein, web 2 and upper cover plate 1,3 one-tenth vertical relations of lower cover.The thickness range of upper cover plate 1 and lower cover 3 is 5-200mm.The thickness range 5-200mm of web 2.The spacing range in two web 2 outsides is 3-100mm.Web 2 outer ledges have groove.Groove size≤web 2 thickness.
Embodiment one:
Consult Fig. 2 and Fig. 3, the utility model mainly is made up of upper cover plate 1, two blocks of webs 2 and lower cover 3.Web 2 and upper cover plate 1, lower cover 3 are vertical, and connect and compose the osed top body structure through weld seam; Web 2 thickness are 200mm, and web 2 is equipped with groove, groove size≤web 2 thickness; Upper cover plate 1 is 200mm with lower cover 3 thickness, and does not beat groove, and both width are all greater than the spacing 100mm in two web 2 outsides.
Embodiment two:
Consult Fig. 4, as a kind of optional mode, provide upper cover plate 1 and lower cover 3 not to beat groove, web 2 is not beaten the girder work of groove simultaneously, and web 2 and upper cover plate 1, lower cover 3 are vertical, and connects and composes the osed top body structure through weld seam.The longeron of this mode is than embodiment one processing and welding more easily, but weld strength is a little less than embodiment one.
