Description

An anti-collision road guardrail that is easy to install

Technical Field

The utility model relates to the technical field of railings, in particular to an anti-collision road railing which is easy to install.

Background Art

Guardrails are mainly used for the protection and safeguarding of personal safety and equipment facilities in residential areas, highways, commercial areas, public places and other occasions; guardrails can be seen everywhere in our lives, and most guardrails are formed by splicing multiple sub-guardrails for the convenience of transportation. During the construction process, construction companies will inevitably encounter protection problems during construction. In order to strengthen safety measures, road guardrails are used to isolate dangerous areas of construction to prevent unrelated personnel from entering the construction scope and causing safety hazards. However, there are still some problems in the application of existing road guardrails.

There is a road construction guardrail with a Chinese patent publication number of CN209082384U, which relates to the field of municipal facilities. The construction guardrail includes two support columns and a folding connecting rod arranged between the two support columns, and the support column is provided with a locking piece that can fix the folding connecting rod at any position within the stretching range; although the existing guardrail has storage properties and can be folded and stretched, which is more convenient for transfer, but if the guardrail structure is hit by a collision, its folding structure is very susceptible to deformation and damage, which will lead to problems such as failure to fold normally or even direct damage, and it is also prone to tipping over after a collision, which will lead to the loss of protective isolation effect. When used at a construction site, if the guardrail is damaged, there will be a great safety hazard if unrelated personnel enter.

Therefore, we propose an anti-collision road guardrail that is easy to install to solve the above-mentioned problems.

Utility Model Content

With the above technical solution, through the provision of the first energy absorbing spring, when the front baffle is impacted, it moves backward and squeezes the first energy absorbing spring, thereby absorbing part of the impact force.

Preferably, two sets of second limit rods are fixedly connected to the rear side of the railing frame, and sliding connection seats are passed through the two side ends of the second limit rods, the rear end face of the front baffle is fixedly connected to a fixed seat, and the rear side axis of the fixed seat is connected to a transmission connecting rod, and the rear end of the transmission connecting rod is connected to the sliding connection seat axis to form a rotating structure.

By adopting the above technical solution, the second limit rod is used to limit the range of movement of the two sets of sliding connection seats. At the same time, the cooperation between the transmission connecting rod and the fixed seat can drive the sliding connection seat to slide outside the second limit rod while the front baffle moves.

Preferably, second energy absorbing springs are passed through both side ends of the second limiting rod, and the outer end of the second energy absorbing spring is fixedly connected to the railing frame, and the inner wall end of the second energy absorbing spring is fixedly connected to the sliding connection seat.

By adopting the above technical solution and setting the second energy absorbing spring, when the front baffle moves backward and drives the sliding connecting seat to move, the second energy absorbing spring can be squeezed, thereby effectively reducing the impact force and effectively protecting the railing body.

Preferably, the fixing bolt is connected to the support rod bearing, and the inner end of the fixing bolt passes through the interior of the railing frame and is threadedly connected thereto, the lower end of the support rod is connected to the positioning seat bearing to form a rotating structure, and two sets of positioning rods are passed through the rear end of the positioning seat, and the positioning rods are slidably connected to the positioning seat.

By adopting the above technical solution, the guardrail body can be supported by setting the support rods in coordination with the positioning seats, and multiple sets of positioning rods are inserted into the ground to fix the positioning seats, which can effectively ensure the stability of the guardrail body and prevent it from tipping over due to collisions or impacts. It can effectively block the construction road and isolate the construction area to prevent unauthorized personnel from entering and causing safety hazards.

In order to achieve the above purpose, the utility model provides the following technical solutions:

Compared with the prior art, the utility model has the following beneficial effects: the anti-collision road guardrail is easy to install;

1. By setting up multiple buffer energy-absorbing structures, the impact force caused by collision or impact can be effectively reduced, the impact force on the guardrail body can be reduced, and the guardrail can be protected from deformation and damage. In addition, the rear support structure can effectively keep the railing vertical after being hit, preventing unrelated personnel from entering the construction area after the railing is hit and collapsed, thereby improving the reliability of protective isolation of the construction road or construction area.

2. Set up a split rear support structure and bottom support structure. Because the bottom support structure is usually heavier, it is easy to separate it from the railing frame bolt connection to improve the convenience of transfer, and the rear support structure can also be quickly disassembled, which is convenient for quick installation and disassembly.
