Example 1, as shown in FIGS. 1-4.

A protection device for road construction comprises a guardrail body 1, wherein a construction site is enclosed by the guardrail body 1. The construction site of the road is isolated from the external environment for protection. The construction site requires: continuous and closed fences are arranged around the construction site according to the regulations; safety protection facilities are also needed to be arranged when multi-storey and high-rise buildings are built. The height of the fence arranged on the main road section and the urban landscape road as well as the airport, wharf and station square in the urban area is not less than 2.5m, and the height of the fence arranged on the other road sections is not less than 1.8 m. The height of the guardrail body 1 is set according to the requirements of a construction site.

An accommodating cavity 2 is formed in the front side of the guardrail body 1, a plurality of rotating shafts 3 are vertically and rotationally connected in the accommodating cavity 2 at equal intervals, rolling bodies 4 are arranged on the rotating shafts, anti-collision belts 5 are wrapped outside the rolling bodies 4, and the anti-collision belts 5 are preferably made of rubber materials and can absorb vibration on one hand; on the other hand, the friction force can be increased, and the rotation is convenient. When the vehicle collides with the crash belt 5, the rolling body 4 drives the rotating shaft to rotate around the rotating connection part. The impact of the vehicle is dispersed forward along the collision-prevention belt 5 along the direction of the vehicle head. Further reducing the impact on the guardrail body 1 and greatly reducing the damage degree of the guardrail body 1. The front side surface of the anti-collision belt 5 extends out of the accommodating cavity 2, so that when a vehicle collides, the vehicle firstly collides with the anti-collision belt 5 instead of directly colliding with the side wall of the guardrail body 1, and the guardrail body 1 is protected by the anti-collision belt 5 and the like. The outer side of the anti-collision belt 5 is coated with an air bag 6, impact can be further reduced through the air bag 6, and the damage degree of the guardrail body 1 is reduced. And an inflation hole 7 is formed in the top surface of the air bag 6, and the air bag 6 is inflated and deflated. And a display board 8 is arranged on one side of the air bag 6 far away from the guardrail body 1. Various materials can be posted to show board 8 to and propaganda information.

The guardrail comprises a guardrail body and is characterized in that a mounting plate 9 is arranged on the top surface of the guardrail body 1, a lamp strip 10 is arranged on one side of an anti-collision strip 5, and the lamp strip 10 is externally connected with a power supply for power supply. The condition that the driver does not notice the guardrail body 1 at night and when the optical fibers are insufficient is avoided, and thus traffic accidents are caused.

The guardrail body 1 is kept away from one side of anticollision area 5 and is installed removal subassembly 11 for to whole protection device, remove, be convenient for install and use. Direct carrying is avoided, and the labor intensity of workers is reduced.

The moving assemblies 11 are arranged in two and are symmetrically arranged about the center of the guardrail body 1. The movable assembly 11 comprises a supporting body 12, a handle 13 and a universal wheel 14, one side, away from the anti-collision belt 5, of the guardrail body 1 is provided with the supporting body 12, the supporting body 12 is of a right-angled triangle structure, the long right-angled edge of the supporting body 12 is provided with the handle 13, and the short right-angled edge of the supporting body 12 is provided with the universal wheel 14. When the whole protection device is moved, the top of the handle 13 is pulled to incline the device, so that the universal wheels 14 are in contact with the ground, and the center of the whole device is positioned in the middle of the supporting body 12, so that the stability of the device in the moving process is ensured, and the device cannot topple over. Pulling the handle 13 moves the position of the device. After the guardrail is moved to a proper position, the handle 13 can be pushed to incline the guardrail device, so that the bottom surface of the guardrail body 1 is contacted with the ground, and the universal wheels 14 are separated from the ground to fix the position.

The bottom of one side of the guardrail body 1 far away from the anti-collision belt 5 is provided with a supporting edge 15 which plays a role of a fulcrum, so that the whole protection device can be conveniently inclined, and the position can be moved.

The utility model discloses when using:

the protective devices are used together to shield and protect a construction site, so that accidents of pedestrians, vehicles and constructors are avoided.

When a shift in position is required. The top of the handle is pulled to incline the device, so that the universal wheels are contacted with the bottom surface, and the center of the whole device is positioned in the middle of the supporting body, thereby ensuring the stability in the moving process and avoiding toppling over. The position of the device can be moved by pulling the handle. After the guardrail is moved to a proper position, the handle can be pushed to incline the device, so that the bottom surface of the guardrail body is contacted with the ground, and the universal wheels are separated from the bottom surface, so that the guardrail can be fixed in position and starts to be used.

When the coming and going vehicle collides with the air bag, the collision-prevention belt drives the rotating shaft through the rolling body to rotate around the rotating connection part of the rotating shaft. And the impact of the vehicle is dispersed forwards along the collision-proof belt along the direction of the vehicle head. Further reducing the impact on the guardrail body and greatly reducing the damage degree of the guardrail body.
