Abstract
The utility model discloses a lifting mechanism for a tipper; the aim of the utility model to provide a lifting mechanism for a tipper with an underslung oil cylinder, a double swinging rod and a forward shifing type compartment, which has the advantages that the structure is simple, the transverse stability of a compartment is good, the lifting capacity is large, and the efficiency is high and is suitable for trippers with long wheel bases. The utility model is composed of an auxiliary tripper frame (1), a draw rod (2), an oil cylinder (3), a triangle arm (4), a compartment (5), a front connecting rod (6) and a rear connecting rod (7), wherein, the auxiliary vehicle frame (1) is connected with a tipper chassis. The rear end of a base frame of the compartment (5) is hinged with the upper end of the rear connecting rod (7). The rear connecting rod (7) is hinged with the rear end of the auxiliary tipper frame (1). The lower end of the front connecting rod (6) is hinged with the middle part of the auxiliary tipper frame (1), and the upper end of the front connecting rod (6) is hinged with the base frame of the compartment (5). The upper end of the triangle arm (4) is hinged with the front end of the base frame of the compartment (5), and the lower end of the triangle arm (4) is hinged with the upper end of the draw rod (2). The lower end of the draw rod (2) is hinged with the front end of the auxiliary tipper frame (1). Both ends of the oil cylinder (3) are respectively hinged with the front end of the auxiliary tipper frame (1) and the middle part of the triangle arm (4). The utility model is suitable for various vehicles, particularly the trippers with long wheel bases.
Description
(1) technical field
The utility model relates to a kind of tipper lifting mechanism, particularly a kind of underlying oil cylinder double pendulum bar compartment reach formula tipper lifting mechanism.
(2) background technology
At present, tipper lifting mechanism mainly contains direct-push and linkage rod group box-like two big classes, all is the fixedly hinge upset of compartment around subframe during lifting.Because structural limitations, existing several tipper lifting mechanisms all can only be used for vehicle wheel base, rear overhang all than short vehicle.When the dumping car wheelbase is longer, reach reasonable distribution in order to make axle load, then its rear overhang is also long.At this moment,, want the lifting angle that reaches desirable, then can cause the rear end, compartment to contact to earth if with existing lifting mechanism lifting compartment.
(3) summary of the invention
The utility model is in order to overcome above deficiency, provide a kind of simple in structure, the compartment lateral stability is good, jacking capacity is big, efficient is high, be applicable to the unsteady oil cylinder double pendulum bar compartment reach formula tipper lifting mechanism of long wheelbase dumping car.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals: the utility model underlying oil cylinder double pendulum bar compartment reach formula tipper lifting mechanism is made of compartment, subframe, triangle arm, pull bar, front rod, rear linking rod and oil cylinder; The underframe rear portion in described compartment and the upper end of rear linking rod are hinged, the lower end of described rear linking rod and the rear end of subframe are hinged, the lower end of described front rod and subframe middle part are hinged, the upper end of front rod and the underframe in compartment are hinged, the underframe front end in the upper end of described triangle arm and compartment is hinged, the lower end of described pull bar and the front end of subframe are hinged, and the lower end of the upper end of pull bar and triangle arm is hinged; The middle part of the upper end of described oil cylinder and triangle arm is hinged, and the lower end of oil cylinder and the front end of subframe are hinged.
Four-bar linkage of the present utility model is made of compartment, subframe, front rod and rear linking rod.Dumping car lifting engine installation of the present utility model is made of triangle arm, pull bar and oil cylinder.The fulcrum in lifting compartment is at the underframe front end in compartment, lifting mechanism efficient height.Front rod and rear linking rod control compartment upturned position, even the effect of the lateral stability of having held concurrently frame is the very long lateral stability that also can guarantee compartment in the lifting process in compartment.And the compartment moves up forward in the lifting process gradually, shortened the compartment rear overhang relatively, thereby realizes turning over self-unloading behind the long wheelbase automobile.
The beneficial effects of the utility model are: (1) is simple and reliable for structure, good manufacturability; (2) after being realized, the automobile of long wheelbase turns over self-unloading; (3) the compartment lateral stability is good, and jacking capacity is big, the efficient height.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1 subframe, 2 pull bars, 3 oil cylinders, 4 triangle arms, 5 compartments, 6 front rods, 7 rear linking rods
(5) specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model underlying oil cylinder double pendulum bar compartment reach formula tipper lifting mechanism is made of subframe 1, pull bar 2, oil cylinder 3, triangle arm 4, compartment 5, front rod 6 and rear linking rod 7.Described compartment 5, subframe 1, front rod 6, rear linking rod 7 constitute four-bar linkage.Described subframe 1 links into an integrated entity with car chassis; The underframe rear end in described compartment 5 and the upper end of rear linking rod 7 are hinged; Described rear linking rod 7 is hinged with the rear end of subframe 1; The middle part of the lower end of described front rod 6 and subframe 1 is hinged, and the underframe in the upper end of front rod 6 and compartment 5 is hinged; The upper end of described triangle arm 4 and compartment 5 underframe front ends are hinged, and the upper end of the lower end of triangle arm 4 and pull bar 2 is hinged, and the front end of the lower end of described pull bar 2 and subframe 1 is hinged, and the two ends of described oil cylinder 3 are hinged with the middle part of the front end of subframe 1, triangle arm 4 respectively.
Using method of the present utility model is:
In dumping car upset self-unloading process, when oil cylinder 3 length increased, the four-bar linkage of being made up of compartment 5, subframe 1, front rod 6, rear linking rod 7 rotated, and compartment 5 moves up forward when realizing the upset self-unloading.When oil cylinder 3 off-loads, compartment 5 falls by deadweight, and lifting mechanism recovers initial position.
