Abstract
Disclosed is a rotary and luffing cab, comprising a cab. It is characterized in that the cab also comprises a rotary jib connected to the cab via articulated points and a hydraulic cylinder, as well as a shaft and a bearing which fasten the rotary jib on the platform. The cab is mainly applicable to machines for heavy-duty operations, such as cranes.
Description
Technical field
The utility model relates to the driver's cab of engineering machinery vehicle, particularly relates to the driver's cab of using on a kind of crawler crane that can turn round pitching.
Background technology
The driver's cab of crawler crane is generally fixed in the prior art, and crawler crane has three kinds of mode of operations in when work: during the lifting weight, in travelling position and the loading and unloading process certainly.Different mode of operations requires driver's cab to have different control positioies, could help the driver satisfactorily to finish the work of different operating state like this. for example, when the lift heavy thing, need driver's cab wraparound rotating shaft to rotate to platform side the place ahead, like this driver can be positive in the face of the lift heavy object space to, the operation visual field is big; Under travelling position, driver's cab can be turned back to the platform dead ahead around axle, not super wide (promptly transporting width), convenient transportation; And in loading and unloading process certainly, driver's cab can be turned back in the face of the position of track frame is installed, and the pitching certain angle leaves enough installing spaces for the installation track frame, the convenient installation.In addition, when driver's cab is turned back to certain angle, also central counterweight can be installed conveniently.
Summary of the invention
In order well to solve the problem of crawler crane driver's cab control position under three kinds of different mode of operations, the utility model proposes a kind of revolution pitching driver's cab, the technical scheme that it adopts is: a kind of revolution pitching driver's cab, comprise driver's cab, also comprise the revoliving arm that is connected with driver's cab by hinge-point and hydraulic actuating cylinder and revoliving arm is fixed on axle and bearing on the platform.
The utlity model has following effect:
Because driver's cab is fixed on the revoliving arm by hinge-point, hydraulic actuating cylinder, driver's cab can turn round certain angle up or down around hinge-point like this, utilizes the pitching of the flexible realization driver's cab of hydraulic actuating cylinder that is:.And revoliving arm by the axle and bearing fixing on platform, it can turn round around axis, can realize that driver's cab manually turns round.
Description of drawings:
Fig. 1 is a driver's cab luffing structure sketch;
Fig. 2 is the rotating structure diagram of driver's cab;
Fig. 3 is a hinge-point connection mode scheme drawing;
Fig. 4 is that revoliving arm is connected to the flat-bed scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises driver's cab 6, also comprises the revoliving arm 5 that is connected with driver's cab 6 by the 3rd hinge-point 3, the 4th hinge-point 4, first hinge-point 1, hydraulic actuating cylinder 7 and second hinge-point 2 and revoliving arm 5 is fixed on plain bearing 10, thrust bearing 9 and axle 11 on the platform 8.
Second hinge-point 2 is fixed on the revoliving arm 5, can act on first hinge-point 1 by hydraulic actuating cylinder 7, make driver's cab 6 upwards turn round certain angle around the 4th hinge-point 4, that is: utilize the pitching of the flexible realization driver's cab of hydraulic actuating cylinder 7, wherein, as shown in Figure 3, first hinge-point 1, the 3rd hinge-point 3, the 4th hinge-point 4 connects by a bearing pin 12. as shown in Figure 4, revoliving arm 5 is fixed on the platform 8 by axle 11 by two plain bearings 10, thrust bearing 9, it can realize that driver's cab manually turns round around the revolution of OO axis.
