Problems solved by technology

For a large field of vision, since the structure composed of the support rod and the warning sign is approximately a plane structure, that is, a vertical plane structure, which does not involve a longitudinal structure, the construction warning device of the plane structure is not eye-catching enough, and its warning effect is not good.

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] see Figure 1-6 , the embodiment of the present invention provides a portable construction warning device for bridges and tunnels, the device specifically includes:

[0044] The base 1, and the ground rail 5 arranged in front of the base 1. It should be noted that the ground rail 5 in the present invention is a track groove dug on the ground.

[0045] The fixed warning device includes: a warning board 22 arranged on the base 1, on which a light warnin...

Abstract

The invention discloses a portable construction warning device for bridges and tunnels. The portable construction warning device comprises a fixed warning device which comprises a warning plate with a lamplight warning mark; a transverse warning device which comprises a plurality of flags and a swinging device used for driving the flags to synchronously swing on a vertical plane; and a longitudinal warning device which comprises a telescopic net rack, a telescopic driving device used for driving the telescopic net rack to stretch forwards and retract backwards, a step plate set and a push-pull device used for pushing and pulling the step plate set to rotate forwards and return to the vertical position backwards. On the basis of an existing fixed warning device, the transverse warning device capable of dynamically moving in the transverse direction is additionally arranged, and the longitudinal warning device capable of dynamically moving in the longitudinal direction is further additionally arranged, so that the construction warning device is not a device similar to a plane structure any more, instead the transverse structure, the longitudinal structure and the vertical structure are combined, the warning device is striking, and therefore the warning effect is good.

Description

technical field [0001] The invention relates to the technical field of construction warning devices, in particular to a portable construction warning device for bridges and tunnels. Background technique [0002] With the rapid development of road traffic construction, more and more road tunnels appear in traffic roads, and construction tunnels are relatively dangerous places, and casual entry is not allowed. Usually, it is necessary to place construction warning signs to remind them to prevent accidents An impact event occurs. [0003] Existing construction warning devices are usually warning signs supported by support rods, and warning characters or symbols are arranged on the warning signs. For a large field of view, since the structure formed by the support rod and the warning sign is approximately a plane structure, that is, a vertical plane structure, which does not involve a longitudinal structure, the construction warning device of the plane structure is not eye-catc...
