Expressway sound barrier production line

Abstract

The expressway sound barrier production line comprises a plurality of sets of steel structure supports, a rail is jointly hoisted on the steel structure supports, a belt is inserted into the rail in a rotating mode, and motors for driving the belt to rotate are installed on the steel structure supports; a plurality of groups of hangers are mounted at the lower end of the belt, hooks are hung at the lower end parts of the hangers, and a sound insulation barrier is hung at the lower end parts of the two groups of hooks; a cover body is installed on the ground, a first opening and a second opening are formed in the two sides of the cover body respectively, and a rail is horizontally inserted into the cover body from the first opening and moves out of the second opening. The inner walls of the two sides, close to the first opening, of the cover body are each provided with a plurality of sprayers, a paint box used for containing paint is placed on the ground, an oil pump is installed on the upper end face of the cover body, an inlet of the oil pump is connected with a feeding pipe inserted into the cover body, and an outlet of the oil pump is connected with discharging pipes inserted into the cover body and connected with the sprayers. The paint spraying efficiency of the sound insulation barrier is improved.

Description

technical field [0001] The present application relates to the field of noise barriers, in particular to a production line of highway noise barriers. Background technique [0002] Expressways are high-grade highways, referred to as expressways. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of China, expressways refer to "capable of adapting to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, dedicated to high-speed driving in separate lanes, and All access-controlled roads". Highway pavement includes main roads, ramps and auxiliary lanes. The main road is the roadway, which is set as the overtaking lane, the fast lane and the slow lane (traveling lane) from left to right according to different numbers. The form of the ramp is complex and diverse, and it is subdivided into interchange ramps, acceleration lanes, deceleration lanes, approach roads, collecting and distributing lanes, a...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the production process of metal sound insulation barriers, since the sound insulation barriers need to ensure a certain degree of corrosion resistance after installation, it is necessary to repair each group after forming. Noise barriers are used for painting operations. Existing manufacturers mostly use manual spraying during the painting process, so the overall spraying efficiency is low and there is room for improvement.
