Abstract
The utility model belongs to an engineering machine which relates to a small digger chassis, comprising two longitudinal girders which are made by channel steel and are parallel to each other. The opening direction of the channel steel is towards inner side; the surface of the opening of the channel steel is welded with a closure plate in order to make each longitudinal girder form a rectangular tubular structure. The front part and the rear part of each longitudinal girder are respectively provided with an 135-type automobile front axle and an 135-type automobile rear axle. The middle sections of the longitudinal girders are provided with two cross beams with are vertical to the longitudinal girders. Two ends of the cross beams are welded on the two longitudinal girders. A clutch and a gearbox are respectively suspended and fixed on the two cross beams which are arranged in front and at back. A transmission shaft is connected between the gearbox and a back axle, and a rectangular diesel engine mounting bracket is arranged on the inner side of the front end of the longitudinal girders. The utility model has simple structure, small volume, low cost, good flexibility, convenient operation in narrow places.
Description
Technical field
The utility model belongs to engineering machinery, relates to a kind of mini-excavator underframe.
Background technology
The underframe of existing excavator equipment generally adopts caterpillar revolving structure, its complex structure, bulky, cost is high, the construction site of the little engineering quantity that particularly is difficult to be applicable to that some spaces are less.
Summary of the invention
Technical problem to be solved in the utility model is, provide one simple in structure, volume is little, at the bottom of the cost, flexibility is good, be convenient to the mini-excavator underframe of constructing in narrow and small place.
Mini-excavator underframe of the present utility model includes two longerons of being made by channel-section steel that are parallel to each other, the opening direction of channel-section steel is all towards the inboard, on the opening surface of channel-section steel, weld shrouding, make longeron form a rectangular tubular structure, front and rear at longeron is separately installed with one 135 automobile front axle and one 135 automobile axle, two crossbeams vertical with longeron are arranged in the stage casing of longeron, the crossbeam two ends are welded on two longerons, hang respectively on two crossbeams that front and back are arranged and be fixed with a clutch and a gearbox, be connected with a power transmission shaft between gearbox and the back axle, be provided with the diesel engine installing rack of a rectangle in the front end inboard of longeron.
The utility model has adopted the longeron of channel-section steel structure and the front and back bridge of 135 automobiles, simple, rationally distributed, little, the maneuverability that takes up room of total, and it is less to be specially adapted to some engineering quantitys, but the less construction site of working space.
