Antiskid automatic elevator for road bridge opening slope

Abstract

The invention discloses an antiskid automatic elevator for a road bridge opening slope. The antiskid automatic elevator for the road bridge opening slope comprises a bridge opening wall body, whereina wall slideway is arranged in the bridge opening wall body; a convex-shaped first sliding chute is formed in the wall slideway; a slidable first sliding block is arranged in the first sliding chute;a rotatable third rotary shaft is arranged in the first sliding block; a rotatable first gear is arranged on the bottom part of the first sliding block; a sliding rack correspondingly meshing with thefirst gear is arranged in the first sliding chute; a rotatable first support frame is connected onto the first sliding block; a telescopic and slidable second support frame is arranged on the first support frame; a slidable elevating frame sliding up and down is further arranged on the second support frame; a rotatable drive rotary wheel is arranged on the slidable elevating frame; and the firstsliding block can be further driven to slide through the rotating of automobile tires, so that an automobile can be pushed to achieve the aim of rescue, and the problem of the occurrence of traffic jam is avoided.

Description

technical field [0001] The invention relates to a road anti-slip lifting device, in particular to an anti-slip automatic hoist for road bridge tunnels and slopes, in particular to an automatic anti-slip hoist for road bridge tunnels and slopes capable of rescuing vehicles when the vehicle is in a slipping state . Background technique [0002] With the continuous improvement of living standards, it has also further promoted the continuous improvement of road construction. In the current road construction process, bridging is one of the indispensable laying methods. When the railway and the road meet, it will pass Bridge holes are built to complete the paving of roads. During the construction of bridge holes, most of them are dug to fill the road surface to avoid intersection with railways, so as to ensure the normal laying of roads. Although digging bridge holes can ensure the normal laying of roads, However, because the bridge hole is in a low-lying terrain, the road surfac...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems existing in the prior art, and to provide a kind of anti-slip automatic hoist for highway bridge tunnels and slopes, which can further drive the rotation of the driving runner through the rotation of the automobile tires, thereby further driving the The rotation of the first gear can further drive the sliding of the first slider through the rotation of the first gear, so that the car can be pushed forward, so as to achieve the purpose of rescue and prevent the vehicle from slipping. The problem of normal driving, thereby avoiding the problem of congestion, and through the rotation of the first support frame on the first slider, the first support frame can be lifted when not in use, thereby ensuring To the normal running of the vehicle, the sliding of the second support frame can be further controlled by the rotation of the turning handle, so as to drive the expansion and contraction of the driving wheel, and the driving wheel can be stretched to the position of the car tire , through the sliding up and down of the sliding lifting frame, the sliding lifting frame can be further slid to the bottom of the car after sliding to the bottom position, and the sliding lifting frame can be further adjusted by the sliding of the lifting frame support, so as to ensure the normal sliding of the sliding lifting frame, and a rubber support plate is respectively arranged on both sides of the sliding lifting frame, so as to ensure that the tires of the vehicle travel on the driving runner
