The specific meaning of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the cab of the construction machine of the present embodiment includes a base 10, a second slide rail 30, and a cab body 40. Wherein, a first slide rail 20 is fixedly arranged on the base 10. The second slide rail 30 is movably disposed on the first slide rail 20, and the second slide rail 30 can slide along the extending direction of the first slide rail 20. The cab body 40 is movably disposed on the second slide rail 30, and the cab body 40 can slide along the extending direction of the second slide rail 30.

With the technical solution of the present embodiment, the second slide rail 30 can slide on the first slide rail 20, and the cab body 40 can slide on the second slide rail 30. The structure enables the cab body 40 to be capable of adjusting the positions of the two sections, so that the adjusting range of the cab body 40 is increased, the visual field blind area of a driver is reduced, and the safety of operation is improved. Therefore, the technical scheme of the embodiment overcomes the defect of small cab adjustment range of the engineering machinery in the prior art.

The base 10 may be fixed to a vehicle body of the construction machine, or a part of the vehicle body of the construction machine may form the base 10. Since the first slide rail 20 is fixed to the base 10, the first slide rail 20 is also fixed to the vehicle body of the construction machine.

Further, the second slide rail 30 slides relative to the first slide rail 20, the cab body 40 slides relative to the second slide rail 30, and the two sliding motions are independent of each other, that is, the cab body 40 can be adjusted in two stages relative to the vehicle body of the engineering machine, so that the adjustment range of the cab body 40 is increased, and the blind area of the view angle of the driver is reduced.

Further, as can be seen from fig. 1, the base 10 is provided with two parallel first sliding rails 20, and the second sliding rails 30 are provided with two second sliding rails respectively disposed above the two first sliding rails 20. The cab body 40 is slidably disposed on the two second slide rails 30. The above structure enables the cab body 40 to smoothly slide with respect to the vehicle body of the construction machine. Further, as will be understood by those skilled in the art with reference to fig. 1, the structure of both sides of the bottom of the cab body 40 is the same, and thus the structure of one side of the bottom of the cab body 40 will be described in detail below.

In the technical solution of the present embodiment, the second slide rail 30 is disposed above the first slide rail 20, and the two are disposed in parallel. A rotary connecting structure 50 is arranged between the first slide rail 20 and the second slide rail 30. When the second slide rail 30 and the first slide rail 20 slide relatively, the rotating connection structure 50 realizes rolling friction between the first slide rail 20 and the second slide rail 30, thereby reducing friction force therebetween.

As can be seen from fig. 3, in the solution of the present embodiment, the upper side of the first slide rail 20 is provided with a convex edge 21, and the convex edge 21 extends toward the side of the first slide rail 20.

Specifically, the upper side of the first slide rail 20 is substantially in an "i" shape, that is, the upper side of the first slide rail 20 forms two convex edges 21 protruding outwards. The roller is rotatably disposed at the bottom of the second slide rail 30, and the roller is engaged with the ledge 21. When the second slide rail 30 slides relative to the first slide rail 20, the roller rolls on the ledge 21, thereby achieving rolling frictional contact between the first slide rail 20 and the second slide rail 30.

As can be seen in fig. 3, the roller is connected to the lower side of the second slide rail 30 by a connecting pin.

As shown in fig. 3, in the solution of this embodiment, the roller is arranged vertically, that is, the axis of the roller is parallel to the vertical direction, the rolling surface of the roller is provided with a groove 51, and the convex edge 21 is matched with the groove 51. In particular, the roller is placed horizontally, i.e. its axis extends in a vertical direction. The convex edge 21 is conical, a conical groove 51 is arranged on the rolling surface of the roller, and the groove 51 is annular. During assembly, the lip 21 snaps into the groove 51 from the side and the roller rolls on the outside of the lip 21.

As can be understood by those skilled in the art with reference to FIGS. 3 and 4, a plurality of rollers are provided in the present embodiment, and the plurality of rollers form two parallel rows. Two rows of rollers are respectively arranged at two sides of the bottom of the second slide rail 30, and when the assembly is carried out, the two rows of rollers are respectively clamped at two sides of the top of the first slide rail 20, so that the first slide rail 20 and the second slide rail 30 are fixed in the vertical direction.

As will be understood by those skilled in the art with reference to fig. 1, since two first slide rails 20 and two second slide rails 30 are provided in the present embodiment, it is also a feasible embodiment to provide only one row of rollers below each second slide rail 30.

Specifically, since the contact surface between the first slide rail 20 and the second slide rail 30 is small, the support structure 60 described above needs to be provided to support the second slide rail 30 in order to prevent horizontal wobbling of the second slide rail 30 when sliding on the first slide rail 20.

As shown in fig. 2, in the solution of the present embodiment, the supporting structure 60 includes a third slide rail 61 and a first slide block 62, one of the third slide rail 61 and the first slide block 62 is disposed on the base 10, and the other is disposed on the side of the second slide rail 30, and the first slide block 62 is adapted to slide on the third slide rail 61.

Specifically, as can be seen in fig. 1 and 3, the second slide rail 30 is in an "i" shape, and the first slide block 62 is disposed at a side of a bottom convex edge of the second slide rail 30 and fastened by a screw. The third slide rail 61 is disposed on the base 10 and located at a side portion of the second slide rail 30, when the assembly is performed, the first slide block 62 is clamped into the third slide rail 61, and when the second slide rail 30 slides relative to the first slide rail 20, the first slide block 62 slides on the third slide rail 61, so as to support the side portion of the second slide rail 30.

The two first sliding blocks 62 and the two third sliding rails 61 are installed in a one-to-one correspondence manner.

As will be understood by those skilled in the art in conjunction with fig. 1, since two first slide rails 20 and two second slide rails 30 are provided in the present embodiment, it is also a feasible embodiment to provide only one set of support structures 60 on the side of each second slide rail 30.

In addition, those skilled in the art will understand that the positions of the first sliding block 62 and the third sliding rail 61 in the present embodiment can be reversed, that is, the first sliding block 62 is disposed on the base 10, and the third sliding rail 61 is disposed on the side of the second sliding rail 30.

The cylinder of the first driving mechanism 70 may be fixedly disposed on the base 10, or may be fixedly disposed on the body of the construction machine, or may be fixedly disposed on the first slide rail 20. The push rod of the first driving mechanism 70 is connected to the end of the second slide rail 30 by a connecting pin. When the push rod of the first driving mechanism 70 extends or retracts, the second slide rail 30 is driven to slide on the first slide rail 20.

Further, the number of the first driving mechanisms 70 is two, and the two first driving mechanisms 70 are respectively connected to the two second slide rails 30.

As shown in fig. 1, the second driving mechanism 80 is also a driving cylinder, and a cylinder body of the second driving mechanism 80 may be fixedly disposed on the base 10, or may be fixedly disposed on a vehicle body of the construction machine, or may be fixedly disposed on the first slide rail 20.
