[0031] The present application is further described in detail below through drawings and examples.

[0032] Reference Figures 1 to 4 The embodiment of the present application provides an anti-collision bridge height limiting device, including a base 1, a fixed vertical rod 9 is fixedly installed on the top of the base 1, a lifting component 2 is arranged inside the fixed vertical rod 9, an anti-collision component 3 is arranged on the top of the lifting component 2, a movable vertical rod 5 is fixedly installed on the top of the anti-collision component 3, a first cross bar 6 and a second cross bar 7 are fixedly installed between the two movable vertical rods 5, a connecting rod 8 is fixedly installed between the first cross bar 6 and the second cross bar 7, a prompt component 4 is arranged on the front of the first cross bar 6 and the second cross bar 7, the lifting component 2 includes a slot 27, the slot 27 is opened inside the fixed vertical rod 9, the lifting rod 21 is inserted into the slot 27, the anti-collision component 3 includes a card block 32, the card block 32 is fixedly installed on the top of the lifting rod 21, and a second magnet block 33 is fixedly installed on the bottom of the movable vertical rod 5, the card block 32 is made of iron, and the second magnet block 33 is inserted into the card block 32.

[0033] The anti-collision component 3 further includes a first magnet block 31 . The first magnet block 31 is fixedly mounted on the outer side of the second cross bar 7 . A plurality of first magnet blocks 31 are evenly arranged on the outer side of the second cross bar 7 .

[0034] In this embodiment, when the overloaded vehicle hits the crossbar, the first magnet block 31 on the second crossbar 7 will be adsorbed on the front of the vehicle. When the first and second crossbars are subjected to impact force, the second magnet block 33 and the card block 32 can no longer support the connection between the two through the adsorption force of the magnet and iron, and the entire first and second crossbars and the movable vertical rod 5 are separated from the lower fixed vertical rod 9, thereby effectively preventing the impact force from being transmitted to the lower fixed vertical rod 9, and after the collision, the first and second crossbars are adsorbed on the vehicle. As the vehicle continues to move, the impact force on the first and second crossbars can be greatly reduced by moving, and adsorption on the vehicle can effectively prevent the first and second crossbars from falling to the ground, thereby greatly reducing the damage to the first and second crossbars, so that when it is hit, the overall damage to the height limiting device is small, and its anti-collision function is achieved; after the collision, the wires connecting the first and second crossbars to the lower part will be torn off, and the torn wires can be reconnected by wiring tools, thereby ensuring that the damage is minimized. After rewiring, the second magnet block 33 can be re-adsorbed inside the card block 32, and the device can be reassembled and put into use.

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, the lifting assembly 2 also includes a screw 22, a threaded hole 23 is opened inside the lifting rod 21, the screw 22 is screwed inside the threaded hole 23, the outer wall of the lifting rod 21 and the inner wall of the slot 27 are in contact with each other, and the cross-sections of the lifting rod 21 and the slot 27 are both square.

[0036] An internal groove 24 is opened inside the fixed vertical rod 9, and a motor 25 is fixedly installed inside the internal groove 24. A rotating rod 26 is fixedly installed at the output end of the motor 25. The rotating rod 26 movably passes through the thin wall between the internal groove 24 and the slot 27. The rotating rod 26 is fixedly installed at the bottom of the screw rod 22.

[0037] The prompt component 4 includes a sign 41, a LED screen 42 is fixedly installed on the front of the sign 41, a fixing block 43 is fixedly installed on the back of the sign 41, and the fixing block 43 is fixedly installed on the outside of the connecting rod 8. The prompt component 4 also includes a horizontal plate 44, which is fixedly installed on the outside of the movable vertical rod 5, and a laser rangefinder 45 is fixedly installed on the bottom of the horizontal plate 44. The laser rangefinder 45 is located above the base 1, and the lens of the laser rangefinder 45 is aligned with the bottom of the first magnet block 31.

[0038] A data processing chip is fixedly installed inside the fixed block 43, and the laser rangefinder 45 and the LED screen 42 are electrically connected via the data processing chip.

[0039] In this embodiment, the motors 25 on both sides are started to drive the screw rod 22 to rotate, and the rotation of the screw rod 22 drives the lifting rod 21 to move up and down. The lifting rod 21 moves up and down, so that the height of the upper movable vertical rod 5 and the first and second horizontal rods can be changed, thereby realizing the adjustment of the height limit. The height between the first magnet block 31 and the base 1 can be measured by the laser rangefinder 45, and the height plus the fixed height of the base 1 itself is the height limit at this time. The data measured by the laser rangefinder 45 is added to the height of the base 1 itself through the data processing chip and displayed on the LED screen 42, so that the effect of real-time display of the height limit can be realized. The data processing chip is a single-chip microcomputer chip, and the single-chip microcomputer can receive and process data by setting a program.

[0040] Working principle: when an overloaded vehicle hits the crossbar, the first magnet block 31 on the second crossbar 7 will be adsorbed on the front of the vehicle. When the first and second crossbars are subjected to impact force, the second magnet block 33 and the clamping block 32 can no longer support the connection between the two through the adsorption force of the magnet and the iron, and the entire first and second crossbars and the movable vertical rod 5 are separated from the lower fixed vertical rod 9, thereby effectively preventing the impact force from being transmitted to the lower fixed vertical rod 9, and after the collision, the first and second crossbars are adsorbed on the vehicle. As the vehicle continues to move, the impact force on the first and second crossbars can be greatly reduced by moving, and being adsorbed on the vehicle can effectively prevent the first and second crossbars from falling to the ground, thereby greatly reducing the damage of the first and second crossbars. The height limiting device is not damaged, so that when it is hit, the overall damage to the height limiting device is small, and its anti-collision function is realized. By starting the motors 25 on both sides to drive the screw rod 22 to rotate, the rotation of the screw rod 22 drives the lifting rod 21 to move up and down. The lifting rod 21 moves up and down, and the height of the upper movable vertical rod 5 and the first and second cross bars can be changed, thereby realizing the adjustment of the height limiting height. The height between the first magnet block 31 and the base 1 can be measured by the laser rangefinder 45, and the height plus the fixed height of the base 1 itself is the height limiting height at this time. The data measured by the laser rangefinder 45 is added to the height of the base 1 itself through the data processing chip and displayed on the LED screen 42, so that the effect of real-time display of the height limiting height can be realized.
