Abstract
The utility model discloses a tractor-type hydraulic excavator, transformed from a tractor body and the rotating mechanism of a hydraulic excavator. The cab of an existing tractor is removed, the rotating mechanism of the hydraulic excavator is installed, a new cab is arranged at the lateral face of the rotating mechanism, and the hydraulic tank is arranged behind the rotating mechanism. The utility model is simple in structure, easy to fabricate, convenient to maintain and reliable in functions. In addition, the utility model has a light weight, strong actuating force, long service life, small inertia of movement and high fabrication precision.
Description
Technical field
The utility model relates to a kind of hydraulic crawler excavator, particularly a kind of tractor formula hydraulic crawler excavator.
Background technology
Along with developing rapidly of industrial or agricultural, builing industry, excavating equipment is widely used in fields such as burying underground of heavy clay industry, municipal engineering, construction of water conservancy works, communication cable.Traditional excavator involves great expense, and therefore tractor mounted hydraulic crawler excavator occurred, though this kind type is cheap, certain practicality is arranged, and fuselage is long, heavy, travels, operates very inconvenient.
Summary of the invention
The purpose of this utility model provides the tractor formula hydraulic crawler excavator of a kind of fuselage weak point, flexible operation.
Tractor formula hydraulic crawler excavator, it is characterized in that: the utility model is made by the rotating mechanism transformation of tractor main body and hydraulic crawler excavator, the driver's cabin of former tractor is removed, rotating mechanism is installed, driver's cabin is located at the side of rotating mechanism, hydraulic oil container is located at the back of rotating mechanism, and oilhole is arranged at top, in the hydraulic oil container side support arm is arranged.
Hydraulic motor is connected with reductor, the travelling gear of reductor is meshed with the internal tooth of rotating mechanism, the internal tooth of rotating mechanism is connected to a fixed by bolt and the bracing frame that is welded on the rotating mechanism chassis, and internal tooth is in transmission connection with the rotating mechanism outer ring mutually by rolling bearing; Oil delivering unit and oil delivering unit chassis are connected and fixed with bolt, and the oil delivering unit chassis is welded on the rotating mechanism chassis, junction plate and the riser bolt of rotating mechanism chassis by being welded on its underpart, and whole whirligig is welded on the tractor girder with riser.
Power of the present utility model output is: by (one) power output shaft transmission → speed increaser → connection hydraulic pump → with fluid is medium → oil delivering unit → distributor → hydraulic motor.Couple together by certain way with oil pipe and to combine, with the mechanical energy of motor, as medium, changing hydraulic pressure into through dynamical element (hydraulic pump) can transmit with fluid, and then change to return through executive component (hydraulic cylinder, hydraulic motor) and be mechanical energy, realize exercises.This part is a prior art, and particular content no longer is described in detail.
The utility model has the advantages that: simple in structure, easy to manufacture, easy to maintenance, reliable operation.In light weight, driving force is big, and the life-span is long, and motional inertia is little, makes the precision height.
Description of drawings
Fig. 1 is the contour structures schematic diagram of tractor formula hydraulic crawler excavator.
Fig. 2 is the rotating mechanism structural representation.
The specific embodiment
See Fig. 1, the utility model is made by the rotating mechanism transformation of tractor main body and hydraulic crawler excavator, the driver's cabin of former tractor is removed, rotating mechanism 22 is installed, driver's cabin 21 is located at the side of rotating mechanism 21, hydraulic oil container 19 is located at the back of rotating mechanism, and oilhole 20 is arranged at top, in the hydraulic oil container side support arm 18 is arranged.
See Fig. 2, hydraulic motor 7 is connected with reductor 6, the travelling gear 5 of reductor 6 is meshed with the internal tooth 2 of rotating mechanism, the internal tooth 2 of rotating mechanism is connected to a fixed by bolt 8 and the bracing frame 14 that is welded on the rotating mechanism chassis 10, and internal tooth 2 is in transmission connection with rotating mechanism outer ring 9 mutually by rolling bearing 3; Oil delivering unit 1 is connected and fixed with oil delivering unit chassis 13 usefulness bolts 15, oil delivering unit chassis 13 is welded on the rotating mechanism chassis 10, rotating mechanism chassis 10 is fixing with riser 11 usefulness bolts 16 by the junction plate 12 that is welded on its underpart, and whole whirligig is welded on the tractor girder 17 with riser 11.
