A rail-type self-propelled guardrail for preventing track blockage

Abstract

The invention discloses a rail-type self-propelled guardrail for preventing track blockage, which comprises a slide rail main body, a traveling gear, a curved rail, a straight rail and a guardrail. A pair of curved rails are symmetrically arranged at both ends of the slide rail main body. Straight rails are arranged between the two ends of the curved rails. In the present invention, gear teeth are uniformly arranged at equal intervals on the top of the main body of the slide rail, and travel gears matching with the gear teeth are provided at the bottom of the guardrail, and a spacer is provided inside the limiting groove between two adjacent gear teeth. There is a retractable blocking block, which uses the mutual cooperation between the walking gear and the gear teeth to increase the stability of the guardrail movement and reduce noise. Finally, it resets and rises under the action of the return spring to keep the upper surface of the main body of the slide rail flat and the sealing at the position of the limit groove, so as to avoid the large dust and impurities falling into the limit groove and causing accumulation to affect the use of the slide rail , thereby increasing the service life of the guardrail.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a rail-type self-propelled guardrail for preventing track blockage. Background technique [0002] In the current economic society, the traffic problem has become increasingly serious. In the great process of social development, the traffic problem is sometimes a serious social problem that must be solved, because it has seriously restricted the process of social development. In the process of social development, such Big problems are urgently needed for us to solve, and in today's big cities, we have the concept of "tidal lane" many years ago for the development of our urban transportation, but in the process of social development due to outsiders The rules and precautions for the "tide lane" are not clear, so I don't know the lane switching time, which brings a lot of unnecessary troubles. [0003] At present, most of the existing guardrails are fixedly arranged in the middl...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a rail-type self-propelled guardrail that prevents track blockage, to solve the problem that most of the existing guardrails proposed in the above background technology are fixedly arranged in the middle of the adjacent roads on both sides, and it is not convenient to adjust the position of the guardrail. To change the lane to solve the increasingly serious traffic jam problem, and when using the track to move the guardrail, it is not convenient to protect the track, dust and impurities are easy to accumulate inside the track and affect the use of the track, the stability of the track movement is poor, easy It affects the service life of the guardrail, and the degree of intelligence is low, so it is not easy to operate and use
