Temporary protection device for expressway construction

Abstract

The invention discloses a temporary protection device for expressway construction. The temporary protection device comprises a shell, a first sliding frame, a second sliding frame, a first extending plate, adjusting supporting columns, flashing lamps and a solar cell panel. The first sliding frame and the second sliding frame are arranged in a vehicle body and are fixedly connected with the shell.The first extending plate is mounted in the first sliding frame, a second extending plate is mounted in the second sliding frame, shift levers are distributed in sequence, fixed grooves are formed inthe side, away from the shell, of the first extending plate, the number of the fixed grooves is two, mounting grooves are formed in the side, away from the shell, of the second extending plate, and the number of the mounting grooves is two. The adjusting supporting columns are arranged on the two sides of the bottom of the shell, the upper ends of the adjusting supporting columns extend into theshell, mounting bases are arranged at the lower ends of the adjusting supporting columns, and supporting frames are fixedly welded to the two sides of each mounting base. The flashing lamps are arranged on the two sides of the front end of the shell, and the solar cell panel is arranged at the upper end of the shell.

Description

technical field [0001] The invention relates to the technical field of expressway construction auxiliary equipment, in particular to a temporary protection device for expressway construction. Background technique [0002] With the continuous development of the social economy, the construction of expressways gradually adapts to the development of industrialization and urbanization. The construction of expressways mostly starts from urban ring roads, radiation roads and busy traffic sections, and gradually becomes urban traffic with expressways as the backbone. With the continuous improvement of people's living standards and the continuous increase of the proportion of cars as a means of travel, the increase in the number of cars will inevitably cause a burden on the expressway, and the road surface of the expressway is prone to damage as time goes by. [0003] In order to avoid traffic inconvenience caused by road damage, it is necessary to regularly maintain and repair the u...

Problems solved by technology

[0004] However, the existing temporary protective devices have poor flexibility. Most of the temporary protective devices need to be arranged in order when they are arranged, and the connection between the protective devices is poor. On the road, a large number of protective devices need to be used for splicing, and the handling of the protective devices is time-consuming and laborious, so it does not meet the existing needs. For this, we propose a temporary protective device for expressway construction
