The technical field is as follows:

the utility model belongs to the technical field of the excavator technique and specifically relates to a liftable excavator driver's cabin that says so.

Background art:

at present, the excavator plays a powerful role in various large projects and capital construction projects, but due to the factors of working environment, the sight range is limited in some occasions or working conditions, the visual field is not wide, the blind area is very large, particularly when a train loads and unloads goods, due to the fact that the train carriage is shielded, a driver can hardly see the conditions in the carriage, and therefore working efficiency is not high, and certain potential safety hazards are increased.

The invention content is as follows:

for solving the problem, overcome the not enough of prior art, the utility model provides a it is convenient to use, simple structure, can go up and down in order to enlarge field of vision scope, reduce the blind area, reduce the liftable excavator driver's cabin of potential safety hazard.

In order to achieve the purpose, the utility model provides a liftable excavator cab, which comprises a base, wherein the upper part of the base is fixedly provided with a connecting seat and a frame, and the connecting seat is positioned inside the frame; the upper part of the frame is hinged with two folding frames, and the other ends of the two folding frames are hinged with connecting plates;

a fixed shaft is fixedly connected between the two folding frames, a hydraulic oil cylinder is hinged in the middle of the fixed shaft, and the other end of the hydraulic oil cylinder is hinged with the connecting seat.

Furthermore, the folding frame comprises two folding arms which are arranged in parallel, and the two folding arms are positioned in the same vertical plane.

Furthermore, the other side of the connecting plate is fixedly connected with a cab.

Further, the connecting plate is arranged at the side lower part of the cab.

Furthermore, the end part of the folding frame is provided with a pin shaft, and the folding frame is hinged with the rack through the pin shaft.

The utility model has the advantages that:

the utility model provides a liftable excavator driver's cabin has and uses conveniently, simple structure, can go up and down in order to enlarge field of vision scope, reduce the blind area, reduce the advantage of potential safety hazard, adopted machinery and hydraulic structure to promote the driver's of excavator driver to certain height, make driver's the field of vision wider, increased work efficiency and reduced the production accident that arouses because field of vision defect and blind area in the work.

FIG. 2 is a schematic view of the descending structure of the present invention;

in the drawings: 1. the base, 2, connecting seat, 3, frame, 4, folding leg, 5, hydraulic cylinder, 6, fixed axle, 7, connecting plate, 8, driver's cabin, 9, round pin axle.

The specific implementation mode is as follows:

for making the purpose, technical scheme and advantage of the utility model implementation clearer, will combine below the utility model discloses an attached 1~ attached 2 of the utility model is right the utility model discloses carry out more detailed description.

The utility model provides a liftable excavator cab, which comprises a base 1, wherein the upper part of the base 1 is fixedly provided with a connecting seat 2 and a frame 3, and the connecting seat 2 is positioned inside the frame 3; the upper part of the frame 3 is hinged with two folding frames 4, and the other ends of the two folding frames 4 are hinged with connecting plates 7; a fixed shaft 6 is fixedly connected between the two folding frames 4, the middle part of the fixed shaft 6 is hinged with a hydraulic oil cylinder 5, and the other end of the hydraulic oil cylinder 5 is hinged with the connecting seat 2; the folding frame 4 comprises two parallel folding arms which are positioned in the same vertical plane; the other side of the connecting plate 7 is fixedly connected with a cab 8; the connecting plate 7 is arranged at the side lower part of the cab 8; the end part of the folding frame 4 is provided with a pin shaft 9, and the folding frame 4 is hinged with the frame 3 through the pin shaft 9.

The utility model discloses a one of them embodiment as follows:

the device comprises a base 1, wherein the upper part of the base 1 is provided with a rack 3 and a connecting seat 2, the rack 3 and the connecting seat 2 are fixedly connected with the base 1, and the connecting seat 2 is arranged inside the rack 3;

frame 3 is frame rack construction, and both sides are provided with the curb plate, and the rear portion is provided with the back plate, encloses into a cell body by curb plate and back plate, is provided with steel frame construction in the cell body, plays the function of consolidating on the one hand, and on the other hand plays certain bearing effect when driver's cabin 8 descends to initial position.

The hydraulic oil cylinder 5 and the folding frame 4 are both arranged in the groove body.
