As shown in fig. 1 and 2, a construction machine of the present embodiment includes a vehicle body 10, a cab body 20, a turntable 30, and a positioning structure 40. The cab body 20 is provided on the vehicle body 10, and the cab body 20 includes a frame 21, an operation device 22 provided in the frame 21, and a seat 23 provided on the operation device 22. A turntable 30 is engaged with the cab body 20, the turntable being adapted to steer the operating device 22. The positioning structure 40 is adapted to fix the relative position between the operating device 22 and the vehicle body 10 after the operating device 22 is steered.

By using the technical scheme of the embodiment, when the engineering machinery needs to be backed or is in other conditions needing the driver to turn around for observation, the positioning structure 40 is detached, the operation device 22 is turned by the rotary table 30 at the moment, then the relative position between the operation device 22 and the vehicle body 10 is fixed by the positioning structure 40, and the driver can observe the conditions backwards and operate the operation device, so that the block-adding running speed and the operation speed are increased. Therefore, the technical scheme of the embodiment overcomes the defect that the driving cab of the wet spraying machine in the prior art is fixedly arranged, so that the reversing in the tunnel is difficult.

The above-mentioned "turning of the operation device 22" includes the case where the operation device 22 is turned forward in fig. 1 to the case where the operation device 22 is turned backward in fig. 2, and also includes the case where the operation device is turned to the facing surface in the direction in fig. 1 or 2. Further, the two different orientations of the operating device 22 in the circumferential direction may be regarded as the operating device 22 performing the steering.

Specifically, the turntable 30 enables the operation device 22 to rotate relative to the frame 21, and the frame 21 is fixedly provided relative to the vehicle body 10, thus enabling the operation device 22 to rotate relative to the vehicle body 10. The positioning structure 40 serves to fix the relative position between the frame 21 and the operating device 22. When the orientation of the operating device 22 needs to be adjusted, the positioning structure 40 is detached, then force is applied to the operating device 22, the operating device is rotated to a certain direction, the positioning structure 40 is installed, and then the relative position between the operating device 22 and the frame 21 is fixed, so that the steering of the operating device 22 is completed.

In this embodiment, the rotation of the operating device 22 can be completed by applying an external force without an additional driving part (e.g., a motor), thereby reducing the cost of the construction machine and increasing no additional potential failure.

The operating device 22 is provided with a first positioning hole, the frame is provided with a second positioning hole, and the positioning structure 40 includes a positioning pin 41, and the positioning pin 41 is inserted into the first positioning hole and the second positioning hole. Specifically, when the driver manipulates the construction machine through the operation device 22, the positioning pin 41 passes through the first positioning hole and the second positioning hole, thereby causing the operation device 22 to be held in a certain orientation. When it is necessary to turn the operation device 22, the positioning pins 41 are removed from the first positioning holes and the second positioning holes, and the operation device 22 can be rotated with respect to the frame 21. After the operation device 22 is turned, the positioning pin 41 is inserted into the first positioning hole and the second positioning hole, so that the operation device 22 can maintain a certain position after turning.

Further, as will be understood by those skilled in the art, in order to allow the operating device 22 to maintain the position at different circumferential orientations, the first positioning hole and the second positioning hole may each be a plurality of holes arranged in the circumferential direction. The positions and the number of the first positioning holes and the second positioning holes can be adaptively set by those skilled in the art according to the positions that the operating device 22 needs to maintain.

Further, the positioning structure is not limited to the positioning pin 41 described above. For example, the positioning structure may also be provided as a screw, hook, or the like.
