Road crossing protective device for liquid conveying pipeline

Abstract

The invention discloses a road crossing protective device for a liquid conveying pipeline. The road crossing protective device comprises more than one protective units; the protective units comprise intermediate impact resisting plates, the side portions of the intermediate impact resisting plates are connected with impact resisting plates, and the intermediate impact resisting plates and the impact resisting plates are assembled to form a ramp across the liquid conveying line; a U-shaped groove for passing through the liquid conveying pipeline is formed in the bottom of the intermediate impact resisting plates; and the intermediate impact resisting plates and the impact resisting plates are connected through mortise and tenon structures, the mortise and tenon structures are trapezoidal clamping slots and trapezoidal protrusions, and the bottom portions of the trapezoidal clamping slots are provided with baffles which prevent connected portions from separating up and down. According tothe road crossing protective device for the liquid conveying pipeline, no exposed handle is arranged, the road crossing protective device can be fixed relative to the ground, the connection between the impact resisting plates is reliable, and the liquid conveying pipeline can be effectively protected; and the pressure resistance of intermediates is enhanced, and the damage to the pipeline due tothe pressure is avoided.

Description

Technical field [0001] The invention belongs to the technical field of road crossing protection devices, and in particular relates to a road crossing protection device used for protecting an infusion pipeline from crossing a road and avoiding being crushed by vehicles. Background technique [0002] At present, there are two main forms of protection devices for infusion pipeline road crossing: [0003] Form 1: The infusion pipeline road crossing facility consisting of a pipe protector with a U-shaped groove and impact plates connected to both sides of the pipe protector. The impact plate is wedge-shaped, and the pipe protector and the impact plate are between Equipped with a locking mechanism that cooperates with each other. The upper surface of the anti-impact plate and the pipe protector are equipped with a non-slip panel, and the interior is equipped with stiffeners. Protect the infusion pipeline from crossing the road to avoid being damaged by cars passing by. [0004] Form 2: C...

AI Technical Summary

Problems solved by technology

[0006] Form 1: T-shaped buckles and T-shaped slots are not easy to make, and the handles are easily damaged on both sides of the impact plate, and the exposed shape is not convenient for the storage of the impact plate. Not easy to fix

[0007] Form 2: steel brazing sleeves are used between the plates to limit the horizontal rotation. Under the condition of large torque, deformation is easy to occur, so that the steel brazing can be inserted; and the middle impact plate of the road protection device adopts Π-shaped structure, and the pipeline is positive The upper plane is horizontal, and it is easy to sag under pressure, causing the pipeline to be damaged under pressure
