Abstract
The utility model discloses a dumper carriage bottom frame. The dumper carriage bottom frame is composed of a first longitudinal beam (1), a second longitudinal beam (2), a third longitudinal beam (3), a first beam (4), a second beam (5) and a wing beam (6), wherein the first beam (4), the second beam (5) and the wing beam (6) are perpendicular to the longitudinal beams. The dumper carriage bottom frame is characterized in that the longitudinal beams are rolling U-shaped pieces with the height larger than the width, the U-shaped openings face upwards, the first longitudinal beam (1) is lower than the second longitudinal beam (2) and the third longitudinal beam (3), the width of the first longitudinal beam (1) is equal to the width of the second longitudinal beam (2) but smaller than the width of the third longitudinal beam (3), and all the beams are disconnected beams and welded to the side faces of the longitudinal beams. When a carriage falls to a dumper frame, the left and right movement of the carriage is limited, the strength of the carriage is enhanced, the shock proof ability of the carriage is improved, the gravity center of a dumper is lowered, the bearing face of the dumper is reduced, the driving stability of the dumper is improved, the strength of the whole bottom frame is enhanced, and the service life of the dumper is prolonged.
Description
Technical field:
The utility model relates to dumping car technical field, is a kind of tipper carriage underframe specifically.
Context request:
At present, dumping car underframe adopts longeron conventionally, and the structure of crossbeam and spar Three kinds of hors d'oeuvres formula, is formed by longeron and some beam weldings, and crossbeam and spar are directly welded on longeron side.Due to the requirement that is subject to the requirement of vehicle load-bearing and is connected with subframe, the height of longeron is generally all in 90mm left and right, wide generally all in 200mm left and right, and vertical depth of beam will be consistent.Although the underframe of this form is very general, also there is following shortcoming:
1, vertical depth of beam is identical, and the sway of railway carriage is not had to position-limiting action, has reduced the safety factor that railway carriage uses;
2, the carrying surface of dumping car is higher, has affected the stability that vehicle uses;
3, underframe penetrates into rear end by four longerons from front end, between longitudinal and cross beam, only rely on weld together, when being subject to parcel impact or heavy duty, due to underframe insufficient strength, underframe is easy to distortion, and easily snap the junction between crossbeam and longeron, reduce the service life of railway carriage.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of tipper carriage underframe is provided, mainly solve existing railway carriage underframe on the sway of railway carriage do not have spacing, carrying surface is high and affect the problems such as service life.
The technical solution of the utility model is: a kind of tipper carriage underframe, is made up of the first longeron, the second longeron, the 3rd longeron and first crossbeam, second cross beam, spar perpendicular to longeron; Its special character is, described longeron is tall and big in wide roll extrusion U-shaped part, U-shaped mouth is arranged upward, longeron is to extend through railway carriage rear end by railway carriage front end, the first described longeron height is lower than the second longeron, the 3rd longeron, and the first described longeron equates with the width of the second longeron, is less than the 3rd longeron, described first crossbeam, second cross beam and spar are disconnection beam, are welded on longeron side.
Further, the position boss reinforcement of weld that described longeron is connected with crossbeam.
Further, the interval between described crossbeam is not identical.
Compared with the prior art a kind of tipper carriage underframe described in the utility model has following good effect: 1, the first longeron height, like this may to spacing the providing of railway carriage lower than the second longeron, the 3rd longeron; 2, longeron employing is tall and big in wide roll extrusion U-shaped part structure, has so not only reduced center of gravity and the carrying surface of whole railway carriage, but also has improved the stability of vehicle operating; 3, longeron extends through railway carriage rear end by railway carriage front end, and crossbeam and spar are welded on longeron side, and this structure has been strengthened the intensity of railway carriage underframe greatly, and has simplified the work capacity of railway carriage underframe splicing welding, has improved production efficiency; 4, the place of longitudinal and cross beam splicing adds boss reinforcement; this structure can actv. protection impact effect to underframe when loading parcel and impacting or when container heavy duty; actv. guarantees the joining quality between longitudinal and cross beam, has extended the service life of whole railway carriage.
Accompanying drawing explanation:
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment:
For Comprehension and Implementation better, describe the utility model in detail below in conjunction with accompanying drawing and instantiation; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 1, take the length of tipper carriage inside as 8600mm is as example, according to designing requirement, adopt the mode of rolling forming to make the first longeron 1, the second longeron 2, the 3rd longeron 3, longeron is tall and big in wide roll extrusion U-shaped part, U-shaped mouth is arranged upward, longeron is to extend through railway carriage rear end by railway carriage front end, the first described longeron 1 is highly 110mm, the height of the second longeron 2 and the 3rd longeron 3 is 120mm, the first longeron 1 equates with the width of the second longeron 2, be less than the 3rd longeron 3, due to the change of longeron arrangement, compare with original arrangement, the center of gravity of whole railway carriage has reduced 10mm than originally, drop between longeron has also played spacing effect to railway carriage, first crossbeam 4, second cross beam 5, spar 6 are disconnection beam, be welded on longeron side, boss 7 reinforcement of welds for the position of its connection, interval between crossbeam is according to the different load-bearing requirements of railway carriage bottom different parts and the arrangement requirement of other railway carriage chassis members, be set to not identical, by this structure, make the design of railway carriage underframe more reasonable.
A kind of tipper carriage underframe described in the utility model, longeron extends through railway carriage rear end from railway carriage front end, and the place of crossbeam and longeron splicing adds boss and reinforces, and has increased the intensity of railway carriage underframe, reduce the blastic deformation of goods to carriage bottom plate, extended the service life of railway carriage.
Claims (3)
1. a tipper carriage underframe, is made up of the first longeron (1), the second longeron (2), the 3rd longeron (3) and first crossbeam (4), second cross beam (5), spar (6) perpendicular to longeron; It is characterized in that, described longeron is tall and big in wide roll extrusion U-shaped part, U-shaped mouth is arranged upward, longeron is to extend through railway carriage rear end by railway carriage front end, described the first longeron (1) height is lower than the second longeron (2), the 3rd longeron (3), and described the first longeron (1) equates with the width of the second longeron (2), is less than the 3rd longeron (3), described first crossbeam (4), second cross beam (5) and spar (6) are disconnection beam, are welded on longeron side.
