Description

Technical Field

[0001] The utility model relates to the technical field of guardrail crossing devices for highway construction, and more specifically, to a guardrail crossing device for highway construction. Background Art

[0002] In current road construction technology, the practical application of guardrail crossing devices for highway construction has certain limitations. First, these devices often cannot easily and safely transport construction workers to the other side of the guardrail. This not only reduces work efficiency but also increases work risks for workers who need to perform road maintenance, sign installation or emergency repair work. Due to the lack of effective crossing methods, workers may need to take dangerous detours, such as climbing over guardrails or detouring a long distance, which is not only time-consuming but also prone to safety accidents.

[0003] Furthermore, existing guardrail crossing devices for highway construction lack flexible adjustment functions. In the actual construction process, the height and shape of guardrails in different sections may vary, which requires the crossing device to be able to easily adjust the height of the crossing plate according to the specific situation. However, current devices often fail to provide such adjustment capabilities, making it difficult for construction teams to quickly adapt when faced with different guardrail structures, which in turn affects construction progress and safety. This inconvenient adjustment method not only limits the versatility of the equipment, but also increases the difficulty of construction to a certain extent, bringing unnecessary challenges to the daily maintenance and emergency construction tasks of highways.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a guardrail crossing device for highway construction, which has the following beneficial effects:

[0017] 1. The design of the conveying mechanism enables the guardrail crossing device for highway construction to have flexible lifting and moving capabilities. Through the cooperation of the lifting frame and the transverse mechanism, the crossing plate can be easily adjusted to a suitable height and position, which is convenient for construction workers or objects to safely cross the guardrail. The lifting function of the lifting frame and the moving ability of the transverse mechanism greatly improve the construction efficiency, reduce the risk of workers bypassing or climbing over the guardrail, and ensure construction safety.

[0018] 2. The follow-up mechanism provides a stable fixing effect for the insertion rod through the cooperation of the contraction block and the compression spring. When the crossing plate needs to be installed or adjusted, the follow-up mechanism can automatically adjust according to the position of the insertion rod to ensure that the crossing plate is firmly fixed on the mobile vehicle. By turning the hexagonal sleeve, the rotation of the threaded tube can be adjusted, thereby changing the position of the contraction block and adjusting the insertion pressure. This design makes the fixing of the crossing plate more reliable, facilitates adaptation to guardrails of different heights, and improves the adaptability and stability of the equipment.

[0019] 3. The transverse movement mechanism realizes the precise horizontal movement of the crossing plate through the parallel setting of the lifting plate and the moving plate and the guidance of the guide rod. When the construction personnel or objects are on the crossing plate, the motor is started, and the crossing plate can be smoothly moved to the other side of the guardrail through the cooperation of the lead screw and the guide rod. This design not only improves the construction efficiency and reduces the labor cost, but also ensures the safety of the construction process and avoids the risk of accidents caused by unstable factors in the crossing process. The flexibility and reliability of the transverse movement mechanism provide great convenience for highway construction. BRIEF DESCRIPTION OF THE DRAWINGS
