Embodiment Construction

[0011] see figure 1 ~Fig. 4, the present invention is made up of roller and adhesive tape; figure 2 It can be seen that the shape of the tape is like a ladder, its upper side 1 and lower side 1a are like the two legs of the ladder, and the connecting part between the upper side 1 and the lower side 1a is like a ladder rack, and the airspace between the rack and the rack is equipped with a Roller 2, roller axle 2a penetrates in the hole of top 1 and bottom 1a with moving fit, and top 1 and bottom 1a bend easily when not tensioned, can pack into roller.

[0012] Fig. 4 is a partial enlargement of the roller shaft 2a. There is an undercut 2a-1 inside the end of the (steel pipe) roller shaft, which is fastened with the inverted cone 2c-1 of the (spherical) bulkhead 2c with an interference fit. The upper and lower sides of the roller shaft 2a Each has a dull head 2c.

[0013] Fig. 3 is the guiding schematic top view of guide wheel 3, at the turning position of endless belt 1, th...

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. Background technique [0002] One of the current guardrails is a pile and the inner side of the pile is connected with a guardrail steel plate; the other is a short pile type or a wave guardrail; as Hangzhou City Express reported on the 2nd edition on May 8, 2007: The double-deck sleeper bus bound for Zhenxiong, Yunnan The bus rushed out of the corrugated protective fence in front of the left-hand lane in Bijie area, Guizhou Province, and fell into the bottom of a valley more than 100 meters deep, killing 17 people and injuring 25 others. Also on April 24, 2007, City Express 19 edition; a passenger car on Changsheng Bridge in Chongqing overturned about h...
