Safety protection device for asphalt pavement construction

Abstract

The invention relates to the field of pavement construction protection, and discloses a safety protection device for asphalt pavement construction, which comprises support rods; moving wheels are mounted at the lower ends of the support rods; a lifting support device is arranged at the lower ends of the support rods; the two support rods are arranged in total; a protection frame is arranged between the two support rods; a protection net is fixedly connected to the inner side of the protection frame; a cavity is formed in the upper end of the protection frame; an anti-climbing device is arranged in the cavity in the upper end of the protection frame; and connecting devices are arranged between the two ends of the protection frame and the support rods. According to the invention, the safety protection device can effectively solve the problem that the transportation cost is increased due to the fact that most of existing protection devices are integrated and inconvenient to disassemble and assemble; and meanwhile, the problem that an anti-theft conical thorn at the upper end of an existing safety protection device cannot be hidden and is prone to stabbing workers is solved.

Description

technical field [0001] The invention relates to the field of road construction protection, in particular to a safety protection device for asphalt road construction. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental facto...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a safety protection device for asphalt pavement construction, which can effectively solve the problem that the structure of the existing protection devices proposed in the above-mentioned background technology is mostly a monolithic structure, which is inconvenient for transportation and leads to increased costs. At the same time, it solves the problem that the anti-theft cone at the upper end of the existing protective device cannot be hidden, and it is easy to stab the staff
