An easy-to-detach guardrail for protection of slope road construction

Abstract

The invention relates to guardrails convenient to disassemble for slope road surface construction protection. Each guardrail comprises a base, a wire mesh, a retracting mechanism, two fixing rods, tworotating rods and two connecting mechanisms. Each retracting mechanism comprises a first driving assembly, a second driving assembly, a transmission assembly, a first rotating shaft, a driven wheel,a sleeve, a first spring, two first lifting blocks, two second springs and two connecting rods. Each connecting mechanism comprises a third driving assembly, a clamping block, a connecting block, a shell, a transmission rod, a supporting rod, a supporting seat and a bolt, wherein each first driving assembly comprises a second motor and a first gear. According to the guardrails convenient to disassemble for slope road surface construction protection, the guardrails are retracted through the retractiing mechanism, thereby reducing the space occupancy rate of the guardrails. The transportation convenience of the guardrails is improved, and the two guardrails are connected together through the connecting mechanisms, so that the connection firmness of the two guardrails is improved, and the disassembly and assembly convenience of the guardrails is also improved.

Description

technical field [0001] The invention relates to the field of road protection equipment, in particular to an easily detachable guardrail used for construction protection on sloped road surfaces. Background technique [0002] The guardrail here refers to the guardrail used for road construction. The guardrail is mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. Guardrails are commonly used Made of steel, in recent years, the plug-in assembled guardrail made of aluminum alloy has become more popular. [0003] Generally, in the process of road construction, in order to improve the safety of construction, people often use guardrails. During the transportation of general guardrails, because of their large size and cannot be retracted, it brings a lot of inconvenience to the transportation of guardrails. Not only ...

Problems solved by technology

[0003] Generally, in the process of road construction, in order to improve the safety of construction, people often use guardrails. During the transportation of general guardrails, because of their large size and cannot be retracted, it brings a lot of inconvenience to the transportation of guardrails. Not only that, the structure of the joint of the two guardrails is generally simple, which not only reduces the firmness of the connection of the two guardrails, but also reduces the convenience of disassembly and assembly of the guardrails, and reduces the practicability of the guardrails.
