Description

Technical Field

[0001] This utility model relates to the field of barrier gate technology, and more specifically, to a barrier gate for highways. Background Technology

[0002] In existing technologies, highway guardrail machines are widely used in road facilities such as highways, bridges, and tunnels for the installation and maintenance of guardrails. However, in existing guardrail machine designs, the length of the guardrails is usually fixed, making it impossible to flexibly adjust according to different road conditions. This problem is particularly prominent in practical applications, especially during highway construction and renovation.

[0003] First, because fixed-length guardrails cannot be adjusted to meet the actual needs of different road sections, their installation may be inappropriate at special road sections such as curves, intersections, ramps, or bridges. For example, on sharp curves or in areas with poor visibility, fixed-length guardrails may not accurately cover the areas requiring protection, leading to a decrease in safety protection. On flat, straight sections, fixed-length guardrails may result in excessive space waste, affecting the road's aesthetic appeal and even increasing construction and transportation costs.

[0004] Secondly, in certain special road sections, such as mountainous areas, plateaus, or wetlands with complex geographical environments, the road conditions vary greatly. Fixed-length guardrails often cannot be properly adapted to the characteristics of the road's undulations and slopes, easily leading to inaccurate installation or failure to meet design standards. For example, in steep slopes or mountainous areas, standard-length guardrails cannot meet the actual needs of installing longer or shorter guardrails, potentially resulting in too many or too few guardrails being installed, failing to effectively protect vehicles or pedestrians.

[0035] Please see Figures 1-5 As a supplementary embodiment of a highway guardrail mechanism with a lifting adjustment mechanism, a position fixing mechanism, and a fixing auxiliary mechanism: A support plate 17 is installed inside the base 1, and a rotary motor 18 is installed on the support plate 17. The output end of the rotary motor 18 is connected to the rotary sleeve 2. One end of the auxiliary rod 4 is connected to a traction rope 19. A connecting frame 20 is installed on the side of the base 1, and one end of the traction rope 19 is connected to the connecting frame 20. A connecting plate 21 is installed at the bottom end of the side wall of the clamping pipe 5, and the connecting plate 21 is fixedly installed on the rotary sleeve 2.

[0036] More specifically, the rotary motor 18 inside the base 1 starts, and its output end is connected to the rotating sleeve 2, driving the rotating sleeve 2 to start rotating. The rotation of the rotating sleeve 2 causes the main rod 3 to slide inside the sleeve, and the auxiliary rod 4 at one end of the main rod 3 moves accordingly. The traction rope 19 connects the auxiliary rod 4 and the connecting frame 20 on the side of the base 1, realizing the lifting and lowering adjustment of the railing through rope transmission. Multiple sets of adjustment holes 6 on the main rod 3 provide different length position selections. The rotation of the outer rotating frame 7 drives the embedded plate 10 to extend into the locking rod 8 through the push-pull rod 11, firmly locking the main rod 3 in the designated position. The ratchet ring 9 provides anti-reverse protection to ensure the stability of the fixed state. The fixing auxiliary mechanism plays its role. The outer rotating ring 12 slides stably on the shrinking rail 23 through the cooperation of the rotating ball block 16 and the shrinking block 14, and the shrinking spring 15 provides tension to ensure the stability and vibration resistance of the entire system.

[0037] In summary, during the use or operation of the overall equipment: when the lifting adjustment mechanism is required, the lifting adjustment mechanism realizes the raising and lowering control of the railing. The rotating sleeve 2 is rotatably installed on the side of the base 1 and is driven by the internal rotating motor 18. The main rod 3 is slidably set in the rotating sleeve 2, which can realize the telescopic adjustment. The auxiliary rod 4 rotatably installed at one end of the main rod 3 is connected to the traction rope 19. The other end of the traction rope 19 is connected to the connecting frame 20 on the side of the base 1. The rotating sleeve 2 is driven to rotate by the rotating motor 18, which drives the main rod 3 and the auxiliary rod 4 to realize the lifting or lowering action, thus completing the opening and closing of the railing.

[0038] When the position fixing mechanism is in operation, it achieves precise locking of the main rod 3 at a specified position. The outer rotating frame 7 is limited to rotate and installed on the outer wall of the clamping tube 5. The clamping tube 5 is fixed on the rotating sleeve 2. When fixing is required, the outer rotating frame 7 rotates and drives multiple sets of embedded plates 10 to rotate through the push-pull rod 11, so that the embedded plates 10 extend into the clamping rod 8 to achieve locking of the main rod 3. The clamping rod 8 extends through the different adjustment holes 6 on the rotating sleeve 2 and the main rod 3 and cooperates with the clamping tube 5 to provide multiple locking position selections. When adjustment is required, the outer rotating frame 7 is rotated in the opposite direction, and the embedded plates 10 move away from the clamping rod 8 to release the locking state.

[0039] When the auxiliary mechanism is required to operate, it provides stable auxiliary support for position fixation. The outer rotating ring 12 is limited to rotating and installed on the outer wall of the clamping tube 5. The outer fixed ring 13 is fixedly installed to provide basic support. Multiple pairs of shrink blocks 14 are slidably installed on the end face of the outer fixed ring 13 and kept in tension by the shrink spring 15. The rotating ball block 16 at the top of the outer rotating ring 12 passes through the pairs of shrink blocks 14 in sequence and slides on the shrink rail 23 to ensure the stable rotation of the outer rotating ring 12. The stable rotation of the outer rotating ring 12 causes the longitudinal moving ring 101 to be embedded in the ratchet ring, so that the ratchet pawl 102 contacts and supports the ratchet ring 9, providing reliable auxiliary positioning and vibration prevention functions.

[0040] The rotary motor 18 inside the base 1 starts, and its output end is connected to the rotating sleeve 2, driving the rotating sleeve 2 to start rotating. The rotation of the rotating sleeve 2 causes the main rod 3 to slide inside the sleeve, and the auxiliary rod 4 at one end of the main rod 3 moves accordingly. The traction rope 19 connects the auxiliary rod 4 and the connecting frame 20 on the side of the base 1, realizing the raising and lowering adjustment of the railing through rope transmission. Multiple sets of adjustment holes 6 on the main rod 3 provide different length position selections. The rotation of the outer rotating frame 7 drives the embedded plate 10 to extend into the locking rod 8 through the push-pull rod 11, firmly locking the main rod 3 in the designated position. The ratchet ring 9 provides anti-reverse protection to ensure the stability of the fixed state. The fixing auxiliary mechanism plays its role. The outer rotating ring 12 slides stably on the shrinking rail 23 through the cooperation of the rotating ball block 16 and the shrinking block 14.
