Abstract
A back door of a self-discharging mine car belongs to the technical field of self-discharging cars. The back door comprises a rear board is welded into a rear door frame formed by a left frame, a right frame, an upper frame and a lower frame, wherein two bilaterally symmetrical first diagonal beams and two bilaterally symmetrical second diagonal beams are welded between the upper frame and the lower frame, the two second diagonal beams are positioned outside the two first diagonal beams, the first diagonal beam and the second diagonal beam which are arranged on the left side are inclined to the top left, the upper ends of the two second diagonal beams are welded at the positions of the inclined angle formed by the upper frame and the left frame and the inclined angle formed by the upper frame and the right frame, and the first diagonal beams and the second diagonal beams are disposed at intervals. According to the back door of the self-discharging mine car, existing transverse beams and longitudinal beams are replaced by the two first diagonal beams and two second diagonal beams, the structure of the back door is simplified, the dead weight is light, the weight of the whole self-discharging mine car is reduced, the whole producing process is simplified, welding pass and welding deformation can be decreased, work load of workers are reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to the dumping car technical field, espespecially a kind of self-unloading mine car back door.
Background technology
The back door structure of the mining railway carriage of existing self-unloading comprises the rectangle rear door frame that is welded in rear plate periphery, and rear door frame is welded by upper, left, down, right frame.Several crossbeams of vertical welding between left and right frame, several longerons of vertical welding between upper and lower frame, crossbeam and the welding of longeron intersection, horizontal stroke, longeron and rear door frame are welded into the matts structure like this.
But the back door of this matts structure is when satisfying strength under shock, and the weight of himself is very large, and the weight of dumping car is increased, and is unfavorable for the development tendency of present tipper carriage loss of weight; The back door manufacturing process trouble of this matts structure needs a lot of welding beads to weld in addition, workman's inefficiency, and welding is many to cause the variation of rear plate material easily, thereby produces welding deformation.
The utility model content
The purpose of this utility model is to provide a kind of self-unloading mine car back door, and it is from heavy and light, thereby the dumping car overall weight is alleviated, and manufacture craft is simple, has improved work efficiency, has reduced welding bead and has reduced welding deformation.
To achieve these goals, technical solution of the present utility model is: a kind of self-unloading mine car back door, comprise rear plate, described rear plate is welded in the rear door frame, described rear door frame is by upper, lower, left, left frame is welded, on wherein said, two symmetrical the first cant beams of welding and two symmetrical the second cant beams between the lower frame, two described the second cant beams are positioned at the outside of two the first cant beams, be positioned at described first of left side, two cant beams all tilt to the upper left side, the upper end of two described the second cant beams is welded in respectively, the angle of left frame and upper, angle between the left frame is between two described the first cant beams, first, all be set in distance between two cant beams.
The utility model self-unloading mine car back door, wherein welding one longeron between the described upper and lower frame between two described the first cant beams.
The utility model self-unloading mine car back door wherein is welded with a crossbeam between two described the first cant beam middle parts.
The utility model self-unloading mine car back door, the handing-over position between wherein said upper, the left, down, right frame is welded with respectively triangle and strengthens gusset.
After adopting such scheme, the utility model self-unloading mine car back door is by being replaced existing several horizontal strokes, longeron by two the first cant beams and two the second cant beams, its designs simplification, deadweight lightens, and makes whole dumping car weight saving, and its processing and making process is simplified, reduced welding bead, reduce welding deformation, reduced workman's work capacity, improved workman's work efficiency.
Description of drawings
Fig. 1 is the first example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door;
Fig. 2 is the second example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door;
Fig. 3 is the 3rd example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door.
Below in conjunction with accompanying drawing, by embodiment the utility model is described further;
The specific embodiment
See also shown in Figure 1, the first example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door, it comprises rear plate 1, rear plate 1 is welded in the rear door frame 2.Rear door frame 2 is to be welded by upper side frame 3, lower frame 4, left frame 5 and left frame 6.Handing-over position between handing-over position between handing-over position between handing-over position between upper side frame 3 and the left frame 5, left frame 5 and the lower frame 4, lower frame 4 and the left frame 6 and left frame 6 and the upper side frame 3 is welded with respectively triangle and strengthens gusset 11, is used for strengthening the intensity of rear door frame 2.Be welded with two symmetrical the first cant beams 7 and two symmetrical the second cant beams 8 between upper side frame 3 and the lower frame 4.Two the second cant beams 8 are positioned at the outside of two the first cant beams 7.The first cant beam 7 and the second cant beam 8 that are positioned at the left side all tilt to the upper left side.The upper end of two the second cant beams 8 is welded in respectively the angle between the angle of upper side frame 3, left frame 5 and upper side frame 3, the left frame 6, between two the first cant beams 7, all be set in distance between the first cant beam 7, the second cant beam 8.
See also shown in Figure 2, the second example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door, the structure of itself and the first embodiment is basic identical, difference is: its structure than the first embodiment has been Duoed a longeron 9.This longeron 9 is welded between two upper side frames 3, lower frame 4 between the first cant beam 7.The increase of this longeron 9 has improved the impact strength at back door.
See also shown in Figure 3, the 3rd example structure scheme drawing at the utility model self-unloading mine car V-type girder construction back door, the structure of itself and the first embodiment is basic identical, difference is, its structure than the first embodiment has been Duoed a crossbeam 10, and this crossbeam 10 is welded between two the first cant beam 7 middle parts.The increase of this crossbeam 10 has improved the impact strength at back door.
The utility model self-unloading mine car back door is by being replaced existing several horizontal strokes, longeron by two the first cant beams 7 and two the second cant beams 8, designs simplification, deadweight lightens, make whole dumping car weight saving, and its processing and making process simplification, reduced welding bead, reduced welding deformation, reduce workman's work capacity, improved workman's work efficiency.
The above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
