Problems solved by technology

At present, the protective devices on both sides of the expressway are mainly composed of columns and railings on them. Both the columns and the railings are rigid materials. When a car hits the railing, it can only rely on the deformation of the railing to damage the energy absorption, but Curtains have limited deformability
In summary, how to solve the problem of the limited energy absorption capacity of existing highway guardrails has become an urgent problem to be solved by those skilled in the art

Abstract

The invention discloses an anti-collision expressway guardrail, which comprises a column, the column is fixedly connected with a fence through a connecting piece, the fence includes a front fence and a rear fence, the number of the connecting pieces is two, and the connecting piece includes a connecting cylinder and a connecting piece. Connecting the ring, one end of the connecting cylinder is fixedly connected with the column, the outer peripheral surface of the other end of the connecting cylinder is provided with a circular protrusion, and the inner peripheral surface of one end of the connecting ring is provided with a circular baffle, and the circular baffle The inner side of the ring-shaped protrusion is attached to the side of the column, the other end of the connecting ring is provided with a connecting plate, the cavity of the connecting ring is filled with buffers, and the two connecting plates are respectively connected to the two rear fences. The middle position of the arc part is fixedly connected, and the part of the connecting cylinder located between the upright post and the annular baffle is covered with a compression spring. The invention solves the technical problem that the existing highway guardrails have limited ability to absorb energy when a collision occurs.

Description

technical field [0001] The invention relates to the technical field of expressway guardrails, in particular to an anti-collision expressway guardrail. Background technique [0002] With the construction of a large number of expressways and the substantial increase of car ownership, the incidence of traffic accidents on expressways is also showing an upward trend. At present, the protective devices on both sides of the expressway are mainly composed of columns and railings on them. Both the columns and the railings are rigid materials. When a car hits the railing, it can only rely on the deformation of the railing to damage the energy absorption, but The deformation capability of the curb is limited. To sum up, how to solve the problem of the limited energy-absorbing capacity of existing highway guardrails has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to overcome the defici...
