Problems solved by technology

[0003] In the existing road construction technology, it is necessary to place a warning frame at an appropriate position before the construction section. The placed warning frame is easy to block the sight of the driver and the construction personnel, and cannot allow people to observe the surrounding environment in time, which is prone to safety accidents

Embodiment 1

[0028] A road surface warning protective frame for road construction, such as Figure 1-8 As shown, it includes a support base 1, a deceleration limit mechanism 2, a clamping mechanism 3 and a warning mechanism 4. The support base 1 is provided with a deceleration limit mechanism 2 for decelerating the vehicle, and the clamping mechanism 3 is located on the support base 1. Above, the warning mechanism 4 for prompting the driver is also arranged on the support base 1 .

[0029] The deceleration limiting mechanism 2 comprises a limiting plate 21, an inclined-plane block 22, a buffer spring 23, a swing groove bar 24 and a first torsion spring 25, and the supporting base 1 is slidably connected with the limiting plate 21, and the limiting plate 21 is used to align the wheels. Positioning is performed so that the automobile cannot continue to move forward. The inclined-plane block 22 used for buffering the automobile wheels is also slidably connected to the support seat 1. A pair o...

Embodiment 2

[0036] On the basis of Example 1, such as Figure 9-11 Shown, also include pushing mechanism 5, and pushing mechanism 5 is located on the warning plate 42, and pushing mechanism 5 includes rotating plate 51, L-shaped bar 52, the 3rd torsion spring 53 and limit bar 54, and rotating plate 51 is fixed. Connected to one side of the warning plate 42, the L-shaped rod 52 is rotatably connected to the bottom of the rotating plate 51, the third torsion spring 53 is connected between the L-shaped rod 52 and the rotating plate 51, and the short limit rod 54 is fixed on the bottom of the L-shaped rod 54. At the bottom of the rotating plate 51 of the rod 52 , the short limiting rod 54 is in contact with the L-shaped rod 52 , and the short limiting rod 54 is used to limit the L-shaped rod 52 .

[0037] Also include reciprocating swing recording mechanism 6, reciprocating swing recording mechanism 6 is located on the support seat 1, reciprocating swing recording mechanism 6 includes movable...

Abstract

The invention relates to the field of road safety, in particular to a road surface warning protection frame for road construction, which comprises a supporting seat, a speed reduction limiting mechanism, a clamping mechanism and the like, a speed reduction limiting mechanism is arranged on the supporting seat, and the clamping mechanism is arranged on the supporting seat. Through the deceleration limiting mechanism, the automobile wheels make contact with the slope block, the automobile wheels push the slope block to move downwards, the slope block buffers the automobile wheels through the action of the buffer spring, so that the automobile is decelerated, the slope block moves downwards to push the swing groove rod to swing, and the swing groove rod swings to drive the limiting plate to move upwards; and the limiting plate moves upwards to limit the wheels, so that the automobile cannot move forwards continuously.

Description

technical field [0001] The invention relates to the field of road safety, in particular to a road surface warning protective frame for road construction. Background technique [0002] When digging pits in public places, roadsides or passages, repairing and installing underground facilities, etc., it is necessary to set up obvious signs and take safety measures. The construction signs are used to announce the road construction ahead. Vehicles should slow down or take a detour. The construction signs are used as temporary signs. Set it at an appropriate position before the construction road section to provide sufficient time for motor vehicles or pedestrians to find signs and take safe evasive actions. [0003] In the existing road construction technology, it is necessary to place a warning frame at an appropriate position before the construction section. The placed warning frame is easy to block the sight of the driver and construction workers, and cannot allow people to obse...
