The frame 10 is regularly arranged with lower mounting unit structures 1, and the working equipment is regularly arranged with upper mounting unit structures below. The number of upper mounting unit structures is less than or equal to the number of lower mounting unit structures, and the plane projections of the upper mounting unit structures all fall on the lower mounting unit structures 1, and the corresponding upper mounting unit structures and lower mounting unit structures 1 are detachably connected.

[0024] In this embodiment, the lower installation unit structures 1 are arranged in a rectangular array, and there are longitudinal intervals A and transverse intervals B between the lower installation unit structures.

[0025] In this embodiment, the working equipment is a man cabin. Upper installation unit structures are arranged longitudinally and transversely below the man cabin, and the longitudinally arranged lower installation unit structures have longitudinal intervals of n*A and K*A, and the transversely arranged lower installation unit structures have longitudinal intervals of B, where n and K are integers.

[0026] In this embodiment, the lower mounting unit structure 1 is in the form of a mounting interface, and the upper mounting unit structure is in the form of a mounting protrusion.

[0027] When the cabin is installed, the upper installation unit structure on the cabin cooperates with the lower installation unit structure 1 at the corresponding position on the vehicle frame to achieve plug-in fixation.

[0028] Embodiment 2: like Figures 6 to 15 As shown, in this embodiment, based on the first embodiment, the upper mounting unit structure cooperates with the lower mounting unit structure to form a quick plug-in mechanism to achieve a quick detachable plug-in connection, thereby achieving insertion and fixation of the two, as well as unlocking and separation.

[0029] Specifically, the upper mounting unit structure includes a cone pin 13 fixedly connected to the working equipment, and a lower end of the cone pin 13 is fixedly provided with a Latin 14 extending downward.

[0030] Latin 14 includes a locking section and a connecting section 15, the connecting section 15 is fixedly connected to the lower end of the cone pin 13; the locking section includes a guide portion 16 in the upper half and a limiting portion 17 in the lower half, the guide portion 16 is a long strip extending forward and backward, the limiting portion 17 is cylindrical and has a diameter larger than the guide portion 16, and the upper side of the limiting portion 17 forms an inclined mating surface 141.

[0031] Specifically, the lower mounting unit structure includes a tapered hole seat 11 fixedly connected to the frame 10, and the tapered hole seat 11 has a tapered hole with a large upper end and a small lower end. The tapered hole cooperates with a tapered pin 13, and the upper end of the tapered hole is open, and the tapered lower end is connected to a horizontal channel extending front and rear. A locking pin 12 is provided in the horizontal channel and slides with the locking pin in the front and rear directions; the locking pin 12 is connected to a locking pin moving mechanism for driving the locking pin 12 to move forward and backward.

The handle 123 is rotated in the reverse direction, driving the lock pin 12 to move backward ( Figure 8 The right side of the figure is the rear side), so that the wedge surface 121 of the locking pin 12 is separated from the matching surface 141 of the Latin 14, and the unlocking is completed. At this time, the guide portion 16 and the guide hole 19 are compared up and down, and the Latin 14 and the tapered pin 13 can be moved upward, thereby separating from the tapered hole seat 11.
