MULTIFUNCTIONAL ROADBLOCK FOR PUBLIC WORKS CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2018/028179
Kind Code:
A1
Abstract:
A multifunctional roadblock for public works construction, comprising: a roadblock body (1), an upper-layer roadblock (2), a lower-layer roadblock (3), a base (4) and a fixed holder (5); the roadblock body (1) is divided into two layers of upper layer and lower layer; the upper-layer roadblock (2) is provided thereon with a lampshade (6), the lampshade (6) is provided therein with a warning lamp (7), and a switch is provided above the lampshade (6); the upper-layer roadblock (2) is provided therein with a battery, the battery is a rechargeable battery; the upper-layer roadblock (2) is located inside the lower-layer roadblock (3), and the base (4) is disposed at the bottom end of the lower-layer roadblock (3); the base (4) is connected to the cylindrical fixed holder (5) through threaded connection; the fixed holder (5) is embedded in ground; the base (4) is provided therein with an electromagnet (8); when the electromagnet (8) is energized, the base (4) and the fixed holder (5) are pulled in; otherwise, the base (4) and the fixed holder (5) are disconnected; a caster (9) in the fixed holder (5) is connected to a bottom surface of the base (4). The pull-in of the electromagnet (8) and the fixed holder (5) can prevent unnecessary movements and overturns of the roadblock, and short-distance free movement of the roadblock can be realized by using the caster (9), thus achieving the combination of fixing and moving.
