[0002] At present, the cab of engineering vehicles is generally rigidly connected to the machine body by bolts. Although the existing cab has the function and purpose of improving the driver's operating comfort and reducing the driver's fatigue intensity, it still has the following disadvantages: the cab is immovable relative to the machine body, which limits the driver's field of view and affects the maintenance performance of the machine.

[0003] like Figure 1 and Figure 2 As shown, the Chinese patent (authorization announcement number CN 211844658U, authorization announcement date is 2020.11.03) "A movable and adjustable cab" includes a cab 1', a guide rail 2', a cab chassis 3', a cylinder 4', a slewing support 10' and a lifting wheel 20', the cab 1' is installed above the cab chassis 3', and the slewing support 10' is arranged between the cab 1' and the cab chassis 3'; guide wheels 5' are pivotally connected to both sides of the bottom of the cab chassis 3', and the guide wheels 5' are slidably connected to the guide rails 2'; the two guide rails 2' are connected to the bottom of the cab chassis 3'. 'It is arranged below the cab 1' along the left and right directions of the cab 1'; the oil cylinder 4' is arranged on the lower side of the cab chassis 3' and is located in the middle of the guide rail 2'. The cylinder body of the oil cylinder 4' is fixedly hinged on the fuselage 15'. The piston rod of the oil cylinder 4' is hinged to the cab chassis 3' to drive the cab chassis 3' to slide back and forth along the guide rail, thereby driving the cab 1' to move laterally relative to the fuselage 15'. When the cab 1' moves to one side, the components at the bottom of the cab 1' are easily exposed, which improves the maintenance performance of the machine. The cab 1' in this patent is an integral structure. The bottom plate 12' of the cab 1' and the cab body 11' are not separated. The two are integrated. When assembling the cab 1', the cab 1' must be welded as a whole first and then installed on the body, and then the seats and other components inside the cab 1' must be installed one by one, which is extremely inconvenient to operate.
