Abstract

The invention discloses a movable fence device for a central separation band of a high-grade highway. The device comprises a fixing base, a supporting rod is fixedly connected to the upper end of thefixing base, and a first circular cavity is formed in the upper end of the supporting rod; a lifting mechanism is installed in the first circular cavity. The movable fence device is convenient to flexibly use, and by adding an anti-collision structure, the whole anti-collision performance is improved; by arranging a buffer mechanism, the damage of a vehicle when colliding with a movable fence canbe effectively reduced; meanwhile, by arranging a spring, the vibration inertia during vehicle collision can be reduced, the dynamic load transmitted to the vehicle is reduced, and accordingly personnel in the vehicle are safer; by arranging a sealing pad between a conical cover and a movable rod, rainwater is prevented from downwards permeating into the first circular cavity, the application quality is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a movable guardrail device for a central divider of a high-grade highway. Background technique [0002] For the central movable guardrail of high-grade highways, a fence-type movable guardrail or a multifunctional movable guardrail is generally used. [0003] The existing fence-type movable guardrail has poor anti-collision performance, and it is difficult to dismantle it in an emergency; the middle part of the multi-functional movable guardrail is thin, and the anti-collision performance is poor, and it is not convenient to adjust the height of the guardrail, and it cannot be adjusted according to the use requirements , poor applicability. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a high-grade highway central divider movable guardrail device. [0005] In order to achieve the above obj...
