External hanging basket for highway concrete anti-collision guardrail construction

Abstract

The invention relates to the technical field of traffic, in particular to an external hanging basket for highway concrete anti-collision guardrail construction, which comprises a road surface and a chassis, concrete guardrails are arranged on the left side and the right side of the top end of the road surface, supporting legs are arranged at four corners of the bottom end of the chassis, and rollers are arranged at the bottom ends of the supporting legs. Third telescopic rods are arranged at the four corners of the bottom end of the chassis correspondingly, a second motor is arranged at the front end of the supporting column, second fixed plates are arranged at the left end and the right end of the second motor correspondingly, fixing bolts are arranged at the front ends of the second fixed plates correspondingly, and the rear ends of the fixing bolts penetrate through the second fixed plates and are fixedly connected with the supporting column; and the circumferential outer wall of the rotating shaft is sleeved with a winding shaft, a steel cable is wound on the circumferential outer wall of the winding shaft, and a lifting hook is arranged at the bottom end of the steel cable through a first rotating ring, so that the limitation is low, the personnel safety is high in the overhauling process, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to an external hanging basket used for the construction of concrete anti-collision guardrails of expressways. Background technique [0002] As we all know, the crash barrier is a kind of road traffic safety facility widely used in highways and bridges. It is usually divided into rigid reinforced concrete crash barriers and flexible waveform crash barriers. Rigid crash barriers are generally made of concrete materials. It is mainly used on bridges, with strong strength and rigidity. When a vehicle hits a rigid anti-collision guardrail, the anti-collision guardrail will not shift and cause the vehicle to buffer. The concrete anti-collision guardrail prevents the vehicle from entering the opposite lane by absorbing the collision energy of the vehicle. or out of the way. [0003] Many bridges are erected in the construction of expressways, and bridges need external hanging baske...

AI Technical Summary

Problems solved by technology

[0003] There are many bridges erected during the erection of the expressway, and the bridge needs to be hung with an external hanging basket maintenance vehicle during the maintenance process. Traffic control is required during the maintenance process, which affects vehicle traffic and increases pressure on the auxiliary road, resulting in high limitations, and During the maintenance process, the personal safety of maintenance personnel is easily endangered, and it is more dangerous for personnel to get on and off the external hanging basket, resulting in low practicability
