Protection fence for rolling wheel rubber belt

Abstract

The invention relates to a guardrail made by rollers and rubber belts. A circular ring loop is formed by a ladder-shaped butter belts, the rollers, guide pulleys and inside and outside guide rails with C-shape section. An upper side and a lower side of the rubber belt are similar to two legs of the ladder, and a gear is connected between the upper side and the lower side. A roller is mounted at a space between the gears. A roller axle is inserted in the holes of the upper side and the lower side in a movable fit manner. When the upper side and the lower side are not tensioned, it is easy to bend, so that the roller can be installed. The C-type inside and outside guide rails are the guide rails of the roller. A multi-elastic rubber layer is clamped between the C-type guide rails. T-type or U-type steel is fastened in the multi-elastic rubber layer. A bolt is used to connect the C-type inside and outside guide rails and to clamp the multi-elastic rubber layer. The upper end of an embedded bolt on a bridge floor or ground crossing a long hole of the C-type inside and outside guide rails is fastened by a large spacer and a double nut. The invention has advantages that the rubber of the waste tyres is used for multi-level energy adsorption and buffering, so as to reduce the casualties of the passengers; due to the guidance of the roller, the drivers have more chances to regulate the automobiles and guarantee the safety of the passengers.

Description

technical field [0001] The invention belongs to the field of road and bridge guardrails, and relates to a roller tape guardrail, especially on the side of a cliff-bank road with many mountains and sharp turns in western China, which can correct the driver who is out of control and return to the right path to save the chance.
