Road sign for building construction

Abstract

The invention discloses a road sign for building construction. The road sign comprises a column pole and a sign body fixedly connected to the side wall of the column pole, a device cavity is formed inthe side wall of the upper end of the column pole, and a telescopic airbag is fixedly connected to the inner top of the device cavity; and a fixing part is fixedly installed at the lower end of the telescopic airbag, and a cleaning mechanism for cleaning the surface of the sign body is installed on the fixing part. By arranging a driving mechanism, the telescopic airbag, the cleaning mechanism, aspiral coil, a magnetic stripe and an indicator light, t the self-cleaning of the surface of the sign body can be realized, so that a driver can clearly grasp the road conditions, manual cleaning isnot needed, the danger of falling during manual cleaning is avoided, the labor intensity of construction workers is reduced, meanwhile, an indicator light strip can emit light during cleaning to enhance the warning effect of the road sign, the driver is attracted to actively watch for obtaining sign content, and the driver can be better helped to get the sign content.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a road sign for construction. Background technique [0002] In the process of bridge construction or road construction, in order to save construction time, it is usually necessary to start multiple construction points at the same time, and then connect multiple points to form a complete bridge line or road line, which leads to the construction site of a project being Across many roads, these roads will be equipped with various road signs to indicate road conditions, to instruct passing drivers to avoid construction sites, and at the same time to indicate the correct driving route to drivers responsible for the transportation of construction site materials . [0003] However, due to the proximity to the construction site, these roads are usually covered with thick dust, and the large trucks that are generally used for transportation to and from the construction sit...

Problems solved by technology

[0003] However, due to the proximity to the construction site, these roads are usually covered with thick dust, and the large trucks that are generally used for transportation to and from the construction site will raise a large amount of dust on the road when driving, so after a period of time, these roads The surface of road signs used in construction sites will be covered with a lot of dust, which will cover the instructions on the signs, resulting in the inability of drivers to obtain road conditions. It is dangerous, and it is easy for the transport driver to find the correct path, which leads to the inability to deliver the construction materials to the required location in time

[0004] In the prior art, construction workers are often regularly arranged to climb to the poles of each road sign, and manually wipe and clean the surface of the sign. This cleaning method needs to climb to a higher height for cleaning, which is not only troublesome to operate, The cleaning efficiency is low, and the cleaning staff will also affect the driver's acquisition of the content of the signs; and because there are many signs on the road, this method also has the disadvantage of high labor intensity, and the height of the signs is relatively high. High, so when the cleaning personnel are cleaning, there will be a danger of falling from a high place, which is dangerous
