[0002] An ETC gantries is a facility installed on highways or urban expressways to implement the Electronic Toll Collection (ETC) system. It typically consists of a gantry equipped with ETC antennas, cameras, and signal lights. These gantries identify vehicles' ETC tags and automatically complete the toll collection process, thereby improving road efficiency and reducing traffic congestion. During inspections of ETC gantries, workers often need to work at heights, such as climbing onto the gantry for inspection or maintenance. To ensure worker safety, they often use fall arrest devices. Fall arrest devices are personal protective equipment designed to prevent workers from falling from heights. They quickly lock and arrest the worker in the event of an accidental fall, effectively preventing falls from height and protecting workers' lives. Using fall arrest devices can also provide greater peace of mind for workers working at heights, reducing distractions caused by safety concerns and improving work efficiency.

[0003] In the prior art, when using the anti-fall device, it is usually necessary to connect the hook of the worker's anti-fall rope and the hook of the anti-fall device. When a sudden fall occurs, the anti-fall device automatically locks the wire rope to prevent the fall. Since a large force is generated at the moment of falling, it is impossible to alleviate this force or protect the worker well, which will cause a certain impact on the worker, which is not conducive to ensuring the comfort of the worker. Therefore, in order to solve the above problems, an ETC gantry anti-fall device is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide an ETC gantry anti-fall device to solve the problem mentioned in the above background technology that a large force will be generated at the moment of falling, and this force cannot be well alleviated or the staff can be protected, which will cause a certain impact on the staff, thereby being not conducive to ensuring the comfort of the staff.

[0005] To achieve the above object, the utility model provides the following technical solution: an ETC gantry anti-fall device, comprising a column, the column comprising a gantry support column, a box body provided on the surface of the gantry support column, a fall arrester fixedly mounted on the inner side of the box body, a hook connected to the bottom end of the fall arrester, a lock buckle movably connected to the surface of the hook;

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. When an unexpected fall occurs, the box is subjected to a force that decreases while the fall arrester is locking the wire rope, causing the movable rod to move inside the sleeve. Combined with the elastic properties of the first spring and the setting of the damping member, the force generated by the sudden fall can be alleviated to a certain extent, thereby reducing the impact and influence on the staff, better ensuring the safety of the staff, and improving the comfort of the staff. At the same time, it can also reduce the influence of the force on the fall arrester, allowing the fall arrester to be better used, thereby facilitating better fall prevention.

[0014] 2. Through the movement of the plug rod in the fixed block and the elastic properties of the second spring, the plug rod can be inserted into the slot, thereby restricting the lock, making the lock less likely to move and preventing the hook from being accidentally opened. The connection between the staff's anti-fall rope and the hook can be more stable, the anti-fall safety is better, and the inspection of the ETC gantry is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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.

[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] An ETC gantry anti-fall device comprises a column, which comprises a gantry support column 1. A box body 11 is provided on the surface of the gantry support column 1. A fall arrester 12 is fixedly mounted on the inner side of the box body 11. A hook 13 is connected to the bottom end of the fall arrester 12. A lock buckle 14 is movably connected to the surface of the hook 13. By connecting the climber's fall arrester rope to the hook 13, the steel wire rope in the fall arrester 12 will automatically shrink during the climbing process. When subjected to external force or sudden falling, the steel wire rope in the fall arrester 12 will be automatically locked, thereby preventing the person from falling suddenly, thereby avoiding the person from falling and ensuring the safety of the ETC gantry inspection work.

[0023] A protective mechanism is provided on the surface of the gantry support column 1, which includes a mounting plate 2, which is fixedly connected to the surface of the gantry support column 1, and a sleeve 21 is fixedly connected to the lower surface of the mounting plate 2, and a first spring 22 is fixedly connected to the inner wall of the sleeve 21, and the bottom end of the first spring 22 is fixedly connected to a connecting block 23, and the bottom end of the connecting block 23 is fixedly connected to a movable rod 24, and a damping member 25 is fixedly connected to the lower surface of the connecting block 23. When the staff falls, the anti-fall device 12 is locked and the movable rod 24 is forced to move and the first spring 22 is deformed. In combination with the action of the damping member 25, the impact force of the fall can be reduced, the impact on the staff can be reduced, and the staff can better inspect the ETC gantry.

[0024] Furthermore, one end of the first spring 22 is fixedly connected to the sleeve 21, and the other end of the first spring 22 is fixedly connected to the connecting block 23. Through the setting of the first spring 22 and the action of the damping member 25, the force of the worker's falling can be alleviated, thereby reducing the burden on the fall arrester 12 and the hook 13, making the use of the fall arrester 12 more stable and safe.

[0025] Furthermore, the movable rod 24 is fixedly connected to the end of the connecting block 23 away from the first spring 22, and the movable rod 24 moves on the inner side of the sleeve 21. Through the setting of the movable rod 24, when the staff falls, the movable rod 24 will move in the sleeve 21 and cooperate with the setting of the first spring 22 and the damping member 25 to alleviate the impact force of falling.

[0026] Furthermore, one end of the movable rod 24 away from the connecting block 23 is fixedly connected to the box body 11, and the damping members 25 are arranged in four groups on the inner side of the sleeve 21. The two ends of the damping members 25 are respectively connected to the connecting block 23 and the sleeve 21. The sleeve 21 and the connecting block 23 are connected through the damping members 25, so that when the staff suddenly falls and the wire rope is locked, the impact force of the fall can be alleviated, thereby improving the safety and comfort of the staff in inspecting the ETC gantry.

[0027] Furthermore, the surface of the hook 13 is provided with an anti-slip mechanism, which includes a fixed block 3, which is fixedly connected to the surface of the hook 13, and a rod 31 is movably connected to the inner side of the fixed block 3. A slot 32 is provided on the inner side of the lock buckle 14, and a second spring 33 is fixedly connected to the surface of the rod 31. By opening the slot 32, when the rod 31 moves and engages with the slot 32, the lock buckle 14 cannot move, thereby preventing the hook 13 from being accidentally opened under the action of external force, so that the connection between the hook 13 and the staff's anti-fall rope can be more stable and safe.

[0028] Furthermore, one end of the second spring 33 is fixedly connected to the fixed block 3, and the other end of the second spring 33 is fixedly connected to the insertion rod 31. Through the setting of the second spring 33, the insertion rod 31 can be reset, and then the insertion rod 31 can be reset and inserted into the slot 32, which can realize the limitation of the lock buckle 14.

[0029] Working principle: When in use, when an accidental fall occurs, the box body 11 is forced to move, and the movable rod 24 moves inside the sleeve 21, and then the first spring 22 is deformed. In conjunction with the setting of the damping member 25, the force generated by the fall can be alleviated to a certain extent, thereby protecting the staff;

[0030] When the hook 13 and the worker's anti-fall rope are connected, the rod 31 is pulled to make the rod 31 move in the fixed block 3 and separate from the slot 32. At this time, the second spring 33 is in a stretched state, and the lock buckle 14 is pinched to make the lock buckle 14 move, so that the hook 13 is opened. After the connection, the lock buckle 14 is released to close the hook 13, and then the rod 31 is released. The rod 31 will reset under the rebound action of the second spring 33, and then the rod 31 and the slot 32 can be inserted, thereby limiting the lock buckle 14 and making it difficult for the hook 13 to be opened.

[0031] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
