Abstract
A kind of bulldozer with roll-over function; belong to technical field of engineering machinery; for solving driver's safety problem; its technical scheme is; it comprises bulldozer body and N-shaped roll-over frame; described N-shaped roll-over frame straddles on the driver's cabin of bulldozer and with driver's cabin and keeps interval, and the base of its both sides column lower end is fixedly connected with the frame of bulldozer by bolt.The utility model in the outer setting of bulldozer cab N-shaped roll-over frame; when there is in the course of the work unexpected rollover in bulldozer; N-shaped roll-over frame can be played a supporting role, and reduces suffered impact and the destruction of driver's cabin, thereby has guaranteed the life security of human pilot.
Description
Technical field
The utility model relates to a kind of bulldozer, can when meeting accident rolling, effectively protect driver's cabin internal staff's safety, belongs to technical field of engineering machinery.
Background technology
The working environment of bulldozer is generally more severe, and work-yard is mostly wasteland, the unavoidable rollover phenomenon that occurs in running.Because the mechanical strength of driver's cabin is less, be difficult to resist the impact that bulldozer rollover is subject to, brought great threat to driver's life security.Therefore the safety that, how to guarantee bulldozer driver is the problem that related design personnel pay close attention to always.But up to the present, still do not find a kind of desirable technical scheme.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of bulldozer with roll-over function is provided, and guarantees to greatest extent driver's safety.
Problem described in the utility model realizes with following technical proposals:
A kind of bulldozer with roll-over function; formation comprises bulldozer body and N-shaped roll-over frame; described N-shaped roll-over frame straddles on the driver's cabin of bulldozer and with driver's cabin and keeps interval, and the base of its both sides column lower end is fixedly connected with the frame of bulldozer by bolt.
The above-mentioned bulldozer with roll-over function, the upper beam of described N-shaped roll-over frame is formed by top board, base plate and former and later two link of boards, and the two ends of top board, base plate and two gussets are connected with two heel posts of N-shaped roll-over frame respectively.
The above-mentioned bulldozer with roll-over function, the outside of two heel posts of described N-shaped roll-over frame is closely provided with handle.
The above-mentioned bulldozer with roll-over function, the both sides, top of described N-shaped roll-over frame are provided with hanger.
The utility model in the outer setting of bulldozer cab N-shaped roll-over frame; when there is in the course of the work unexpected rollover in bulldozer; N-shaped roll-over frame can be played a supporting role, and reduces suffered impact and the destruction of driver's cabin, thereby has guaranteed the life security of human pilot.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model (not drawing bulldozer body in figure);
Fig. 2 is the structural representation of N-shaped roll-over frame;
Fig. 3 is A-A partial sectional view.
In figure, each label is: 1, top board; 2, hanger; 3, gusset; 4, base plate; 5, column; 6, base; 7, N-shaped roll-over frame; 8, handle; 9, bolt.
The specific embodiment
Referring to Fig. 1～Fig. 3; the utility model comprises bulldozer body (not shown in FIG.), N-shaped roll-over frame 7, hanger 2, base 6 and handle 8; wherein; N-shaped roll-over frame 7 comprises two columns 5 and by top board 1, base plate 4 and two crossbeams that gusset 3 surrounds; the upper end of two columns 5 is connected with the two ends of crossbeam respectively, and the base 6 of lower end is fixedly connected with the frame of bulldozer by bolt 9.
N-shaped roll-over frame 7 is positioned at the postmedian of driver's cabin; its crossbeam be positioned at driver's seat directly over; when normal work, can not form obstruction to driver's operation and sight line; but when vehicle burst is toppled over, is rolled; but can effectively keep out external impact for driver's cabin; alleviate the destruction that driver's cabin is caused, protect to greatest extent driver's safety.
Handle 8 is for the upper and lower vehicle of driver assistance; Bolt 9 is for fixing N-shaped roll-over frame 7; make it to form an integral body with the frame of bulldozer; between N-shaped roll-over frame 7 and driver's cabin, there is certain deformation space; when there is less deformation in N-shaped roll-over frame 7; can directly to driver's cabin, not damage, thereby effectively protect the safety of driving indoor occupant.
Left and right two columns 5 directly weld together with top board 1, front and back gusset 3, base plate 4, base 6, hanger 2 is welded on top board 1, make whole device there is good rigidity, the utility model has passed through side direction loading, Vertical loading, longitudinally loading, junk test and material at low temperature performance etc. and has detected test, overall performance has reached designing requirement, meets the requirement of relevant national standard.
The utility model has overcome the shortcoming that existing bulldozer cab can not meet safety, operability and aesthetic property requirement simultaneously, not only can guarantee to greatest extent to drive the safety of indoor occupant, and pilot's line of vision and course of normal operation are not exerted an influence.
