[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1: A protective device for construction engineering, such as Figure 1-Figure 3 As shown, it includes two mounting columns 1, and the bottom of each mounting column 1 is connected to a base 2 by bolts. The base 2 is hollow. Two cross bars 3 are fixed to one of the mounting columns 1, and the two cross bars 3 are symmetrically arranged. Two threaded rods 4 are rotatably connected to the other mounting column 1, and the two threaded rods 4 are symmetrically arranged. The threaded rods 4 are provided with threads, and the threaded rods 4 are connected to the cross bars 3 by threads. The threaded rods 4 are used to drive the cross bars 3 to move. An adjustment mechanism is provided on one of the mounting columns 1, and a moving mechanism is provided on the base 2. The adjustment mechanism is used to adjust the protective distance to facilitate adaptation to construction sites of different widths and improve versatility. The moving mechanism is used to move the base 2 to facilitate change of placement position and improve flexibility.

[0018] The adjustment mechanism includes a mounting frame 5, wherein the mounting frame 5 is fixedly connected to one of the mounting columns 1, and a motor 6 is fixedly connected to the mounting frame 5. The output shaft of the motor 6 is fixedly connected to one of the threaded rods 4, and the motor 6 is used to drive one of the threaded rods 4 to rotate. A driving wheel 7 is fixedly connected to one of the threaded rods 4, and one of the threaded rods 4 is used to drive the driving wheel 7 to rotate. A driven wheel 8 is fixedly connected to the other threaded rod 4, and a transmission belt 9 is wound between the driving wheel 7 and the driven wheel 8, and the driving wheel 7 drives the driven wheel 8 through the transmission belt 9.

[0019] Initially, the staff moves the device to the edge of the construction site, and the crossbar 3 and the threaded rod 4 will block the edge of the construction site to prevent passers-by from entering. When the distance between the two installation columns 1 is too close, the staff starts the motor 6, and the output shaft of the motor 6 rotates to drive one of the threaded rods 4 to rotate, and the rotation of one of the threaded rods 4 drives the driving wheel 7 to rotate, and the driving wheel 7 drives the driven wheel 8 to rotate through the transmission belt 9, and the rotation of the driven wheel 8 drives the other threaded rod 4 to rotate. Under the action of the threads on the threaded rod 4, the crossbar 3 will move in the direction away from one of the installation columns 1, and the movement of the crossbar 3 in the direction away from one of the installation columns 1 drives the other installation column 1 to move in the direction away from one of the installation columns 1, thereby increasing the protective distance. When the two When the distance between the mounting columns 1 is too far, the staff adjusts the motor 6 to rotate in the opposite direction, and the output shaft of the motor 6 rotates in the opposite direction to drive one of the threaded rods 4 to rotate in the opposite direction, and the reverse rotation of one of the threaded rods 4 drives the driving wheel 7 to rotate in the opposite direction, and the driving wheel 7 drives the driven wheel 8 to rotate in the opposite direction through the transmission belt 9, and the reverse rotation of the driven wheel 8 drives the other threaded rod 4 to rotate in the opposite direction. Under the action of the threads on the threaded rod 4, the cross bar 3 will move toward the direction close to one of the mounting columns 1, and the movement of the cross bar 3 toward the direction close to one of the mounting columns 1 drives the other mounting column 1 to move toward the direction close to one of the mounting columns 1, thereby reducing the protective distance. Through the above operation, the protective distance can be conveniently adjusted to adapt to construction sites of different widths and improve versatility.

[0020] Example 2: Based on Example 1, Figure 1-Figure 3 As shown, the moving mechanism includes a rotating shaft 10, which is rotatably connected to the base 2, and the base 2 is used to drive the rotating shaft 10 to move. A slot is provided on the rotating shaft 10, and a flip seat 11 is fixedly connected to the rotating shaft 10. The rotating shaft 10 is used to drive the flip seat 11 to rotate. A torsion spring 12 is provided between the flip seat 11 and the base 2, and the torsion spring 12 is used to drive the flip seat 11 to reset. A roller 13 is rotatably connected to the flip seat 11, and the flip seat 11 is used to drive the roller 13 to rotate. The roller 13 is located in the base 2, and a locking assembly is provided on the base 2.

[0021] The locking assembly includes a sliding frame 14, which is slidably connected to the base 2. A reset spring 15 is provided between the sliding frame 14 and the base 2. The reset spring 15 is used to drive the sliding frame 14 to reset. A quadrangular prism 16 is fixed to one side of the sliding frame 14. The sliding frame 14 is used to drive the quadrangular prism 16 to move. One end of the quadrangular prism 16 is located in the slot of the rotating shaft 10.

[0022] It also includes a mounting seat 17, which is fixed to the mounting column 1, and a bracket 18 is rotatably connected to the mounting seat 17. The upper part of the mounting column 1 is threadedly connected to a bolt 19, and the bolt 19 is threadedly connected to the bracket 18.

[0023] Initially, the roller 13 is located in the base 2, the torsion spring 12 is twisted, the quadrangular prism 16 clamps the rotating shaft 10, and then clamps the flip seat 11, the torsion spring 12 and the roller 13. When the position of the device needs to be moved, the staff pulls out the sliding frame 14 horizontally, the reset spring 15 is stretched, the sliding frame 14 moves horizontally, and the quadrangular prism 16 moves horizontally, and the quadrangular prism 16 moves horizontally and breaks away from the rotating shaft 10. The quadrangular prism 16 no longer clamps the rotating shaft 10, and no longer clamps the flip seat 11, the torsion spring 12 and the roller 13. The torsion spring 12 will rebound and The flip seat 11 is driven to rotate, and the rotation of the flip seat 11 drives the rotating shaft 10 and the roller 13 to rotate. After the roller 13 rotates to a vertical state, the staff releases the sliding frame 14, and the reset spring 15 rebounds and drives the sliding frame 14 to move in the opposite direction. The reverse movement of the moving frame drives the quadrangular prism 16 to move in the opposite direction, and the quadrangular prism 16 re-enters the slot of the rotating shaft 10. The quadrangular prism 16 re-engages the rotating shaft 10, and then re-engages the flip seat 11, the torsion spring 12 and the roller 13. Through the above operation, the base 2 can be easily moved, the placement position can be changed, and flexibility can be improved.
