Each set of movable feet 3 includes at least one foot 31, as shown in the figure. Figure 4 and Figure 5As shown in the figure, the foot 31 comprises a mounting plate 311, a rolling driving part and a pneumatic driving part; the rolling driving part comprises a rolling motor 312 and a rolling wheel set 313 respectively mounted on the mounting plate 311; the rolling motor 312 is connected with the rolling wheel set 313 to drive the rolling wheel set 313 to roll; the pneumatic driving part comprises a telescopic cylinder 314, a pneumatic device and a suction cup 315 mounted on the mounting plate 311; the pneumatic device is connected with the telescopic cylinder 314 to move with the telescopic cylinder 314; the suction cup 315 is connected with the pneumatic device to move with the pneumatic device and be switched by the pneumatic device to a negative pressure state.

[0046] When the elevation angle of the boom 1 is a small elevation angle, the rolling wheel set 313 is driven by the rolling motor 312 to rotate, and the friction between the rolling wheel set 313 and the boom 1 is used to move the climbing arm mechanism to realize rolling movement; when the elevation angle of the boom 1 is a large elevation angle, the friction between the rolling wheel set 313 and the boom 1 is not enough to drive the patch device to move, and the suction type movement is switched; the process of suction type movement is as follows: for a group of moving feet 3, the suction cup 315 is driven by the pneumatic device to move towards the boom 1 and create a negative pressure environment, so that the suction cup 315 adsorbs the boom 1, and another group of moving feet 3 is driven by the electric push rod 4 to move, so as to change the relative position of the two groups of moving feet 3, and the above-mentioned actions are alternately realized to realize suction type movement.

The four feet 31 arranged opposite to each other clamp the boom 1, so that the patch device can stably move along the boom 1. When the mobile feet 3 and the boom 1 are separated or installed, the first linkage mechanism 32 is used to move the two groups of feet 31 away from each other, and the second linkage mechanism 33 is used to move the two feet 31 in the same group away from each other, so that the mobile feet 3 are unfolded, thereby facilitating the boom 1 to be placed in the mobile feet 3 or moved out of the mobile feet 3.

When the opening and closing cylinder 321 acts, it drives the rectangular frame 324 to move, so that the two fourth connecting rods 323 rotate around the hinged point on the fixed seat 322, thereby driving the two groups of feet 31 to move relatively.
