[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. Embodiment 1

[0030] Refer to Figures 1 to 9 As shown, a self-driven anti-collision device for a distributed embedded lifting and anchoring column 2 includes: a guide rail 5, an anti-collision guardrail 1 slidably connected to the top of the guide rail 5, a guardrail translation device 4 provided on the back of the anti-collision guardrail 1, and a plurality of embedded sleeves 6 arranged along the guide rail 5; a plurality of vertically arranged outer sleeves 102 of columns are provided on the anti-collision guardrail 1, and a lifting and anchoring column 2 is sleeved in each outer sleeve 102 of the column; a column driving device 3 is provided in each outer sleeve 102 of the column; the distance between the plurality of embedded sleeves 6 is the same as the distance between the outer sleeves 102 of the columns; in this embodiment, the guide rail 5 is composed of two groups of parallel rail bodies, the length of the guide rail 5 is at least twice that of the anti-collision guardrail 1, the rail bodies are fixed on the concrete foundation 7 through the anchoring bolts 501, and the plurality of embedded sleeves 6 are arranged between the two groups of parallel rail bodies; Such as Figures 6 to 9As shown in the figure, the lifting and anchoring column 2 includes: a lifting column 201, a laser scanning and positioning device 203 provided at the bottom of the lifting column 201, and a plurality of fine-tuning push rods 204 provided on the bottom side wall of the outer column sleeve 102; the push rod of the fine-tuning push rod 204 passes through the outer column sleeve 102 and abuts against the side wall of the lifting column 201; in this embodiment, four fine-tuning push rods 204 are provided, and the four fine-tuning push rods 204 are arranged at equal spans on the bottom side wall of the outer column sleeve 102. By arranging a plurality of vertically arranged outer column sleeves 102, corresponding to arranging a plurality of lifting and anchoring columns 2, a plurality of column driving devices 3, and a plurality of embedded sleeves 6, when the self-driving anti-collision device is in the closed state, multi-point anchoring is formed, the anti-collision level of the self-driving anti-collision device is improved, and it is applicable to the entrances and exits of highway facilities along the line. While the self-driving anti-collision device has the anti-collision function, it realizes the self-opening function, and the positioning is more accurate, without manual operation, reducing the time and labor intensity required for manual operation. Especially on the high-speed section, the risk of traffic accidents caused by workers' operations is reduced.

[0031] The column driving device 3 includes: a spherical bearing 303 rotatably connected to the top of the outer column sleeve 102, and an electric push rod 304 provided at the bottom of the spherical bearing 303; a displacement sensor is provided on the electric push rod 304, and the push rod of the electric push rod 304 is connected to the lifting column 201.

One end of the crossbeam sleeve 105 is placed inside the crossbeam 101 of the front frame unit, and the other end is placed inside the crossbeam 101 of the rear frame unit. Connecting holes are provided on the side surfaces at both ends of the crossbeam 101 and the crossbeam sleeve 105. The crossbeam sleeve 105 is used to reduce the displacement change between adjacent frame units.

[0040] In this embodiment, preferably, a mounting plate 106 is provided above the base 103, and a box body 107 is provided on the mounting plate 106. The box body 107 is an inverted U-shaped bent plate. Embodiment 3
