Problems solved by technology

[0002] The protective railing technology in the prior art is relatively rich, and its protective effect is good, which can ensure the safety of construction. However, these protective railings are large in size and inconvenient to disassemble. After disassembly, they still occupy a lot of space. When they need to be transported or stored It seems to take up a lot of space, which leads to increased transportation and storage costs, and affects the benefits of the enterprise. Moreover, the warning effect of the protective fence is not strong, and it cannot play a good role in reminding and warning in the environment with poor light, forming a certain Potential safety hazard, easily overlooked by pedestrians
[0003] Therefore, there is an urgent need to develop a foldable mobile fence for building construction that can be folded and folded, and can play a good warning role, to overcome the shortcomings of the protective fence in the prior art that occupy a large area and have a weak warning effect

Abstract

The invention discloses a folding guardrail convenient for rapid highway construction. The folding guardrail convenient for rapid highway construction comprises a bottom support; the bottom support isof a cuboid-shaped frame body structure; self-locking pulleys are mounted on the lower surface of the bottom support; a first guardrail is mounted on the upper surface of the bottom support; a jack is arranged on the upside in the first guardrail; an electric control box body is arranged on the surface of the external side of the first guardrail; a transverse connecting rod is connected above theelectric control box body; a first hinging pin is arranged at the upper end of the jack; a rubber ball can enable the wear of a folding rotating rod to be reduced in the guardrail folding process sothat the floor space of the guardrail is reduced, the space utilization rate is increased and the service life of a device can be prolonged; the rapid construction of highways is made convenient, a compression spring can keep the stable connection and mounting of a vertical supporting rod in a connecting device, vibration generated by an outside force effect is prevented, and meanwhile, a pressingeffect can also be realized during folding.

Description

Technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a folding guardrail that is convenient for express highway construction. Background technique [0002] The protective railing technology in the prior art is relatively rich, and its protective effect is good, which can ensure the safety of construction. However, these protective railings are large in size and inconvenient to disassemble. After disassembly, they still occupy more space and need to be transported or stored. Appears to take up extra space, leading to increased transportation and storage costs, affecting corporate efficiency, and the warning function of the protective fence is not strong, and it cannot play a good reminder and warning function in a poorly lit environment, forming a certain Safety hazards can easily be ignored by pedestrians. [0003] Therefore, there is an urgent need to develop a foldable movable protective fence for building construct...
