Description

Technical Field

[0001] The present invention relates to the field of road traffic, and in particular to a traffic anti-collision guardrail with an accident mark. Background Art

[0002] In some remote areas, vehicles may easily hit guardrails due to drivers' unfamiliarity with the roads. The existing guardrail structure is relatively simple, and it is difficult to add anti-collision facilities according to actual conditions. In addition, rescue vehicles are usually required to tow the vehicle when a collision occurs. However, in such remote areas, there are no landmark buildings and the GPS signal is weak. It is difficult for the accident driver to provide an accurate location, especially at night. It is difficult for the tow truck to find the location of the accident vehicle in time. Therefore, there is a need for an anti-collision guardrail that can quickly mark the location after the collision, so as to help rescue vehicles find the accident site more quickly and carry out rescue.

[0029] In this embodiment, the anti-collision component 2 includes a fixed frame 20, two fixed frames 20 are symmetrically arranged above and below, and a number of rollers 21 are rotatably connected between the two fixed frames 20. A sliding rod 22 is fixedly connected to the fixed frame 20, and the sliding rod 22 is slidably connected to the guardrail plate 1, and one end of the sliding rod 22 that extends the guardrail plate 1 is fixedly connected to a block 23, and a spring 24 is provided on the sliding rod 22 between the fixed frame 20 and the guardrail plate 1.

[0031] In this embodiment, the inflation device 5 includes a gas cylinder 51 and a gas valve 52. The valve shaft 521 of the gas valve 52 is fixedly connected to the vertical plate 31. A second gear 53 is fixedly connected to the valve shaft 521, and the second gear 53 meshes with the lower gear 403. The gas outlet end of the gas cylinder 51 is connected to one end of the gas valve 52 via an air pipe. The other end of the gas valve 52 is connected to the rotary joint 72 via the air pipe. The gas cylinder 51 contains a high-pressure light gas. Helium can be selected as the light gas.

[0032] In this embodiment, the reeling device 7 includes a reel 70, and two sliding rollers 71 are rotatably connected to the cover plate 33. The rotating shaft 701 of the reel 70 is a tube body with an air inlet 702 at one end, and a rotary joint 72 is provided at the air inlet 702. The rotating shaft 701 is provided with an air outlet 703, and the air outlet 703 is connected to a hose 73. The hose 73 is wound on the reel, and its end passes between the two sliding rollers 71 and is connected to the balloon 6. On the one hand, the hose 73 is used to inflate the balloon 6, and on the other hand, it replaces the rope to restrain the balloon 6, so that the balloon 6 can hover at a certain height.

[0033] An air nozzle 74 is also provided on the hose 73, and the air nozzle 74 can be used to release the gas in the balloon 6. The rotating shaft 701 is rotatably connected to the vertical plate 31, and a gear 75 is fixedly connected to the rotating shaft 701, and the gear 75 is engaged with the upper tooth 401. A drive shaft 76 is also provided at the center of the unwinding reel 70, and the drive shaft 76 is rotatably connected to the box body 3, and a handle 77 is fixedly connected at its end. The surface of the balloon 6 and the surface of the trachea are provided with a fluorescent layer, and the cover 33 is made of transparent material to facilitate sunlight exposure to the fluorescent coating.

[0034] The cam 812 is connected to the cam 814 and the cam 816 is connected to the cam 817 so that the cam 818 can be turned to the cam 819. The cam 814 is connected to the cam 818 by the spring 820. When the cam 818 is turned to the cam 819, the cam 816 is turned to the cam 817. When the cam 818 is turned to the cam 819, the cam 816 is turned to the cam 818. When the cam 818 is turned to the cam 819, the cam 816 is turned to the cam 817.

[0035] Working process and principle:

[0036] When the vehicle hits the drum 21, the drum 21 rotates, so that the impact force is dispersed along the direction of the guardrail 1. At the same time, the fixing frame 20 compresses the spring 1 24 to achieve buffering and reduce impact damage.

[0037] The original gear 75 is engaged with the upper tooth 401, and the rack 40 is stuck by the lock tongue 451. Due to the inclined structure of the lock tongue 451 and the lock tooth 421, the rack 40 can move freely to the left, but if the lock tongue 451 does not actively retract, it cannot move to the left and then automatically reset, thereby achieving the main jam. When the rack 40 does not move, the unwinding reel 70 is locked and does not move.

[0038] like Figure 4 As shown, when the fixing frame 20 moves toward the protective plate, pushing the push rod 41, the rack 1 40 moves to the left, the upper tooth 401 of the rack 1 40 drives the gear 1 75 to rotate, and the lower tooth 403 drives the gear 2 53 to rotate. As the rack 1 40 is hit and moves to the left, the gear 1 75 is in the notch 402. Since the rack 1 40 is stuck by the lock tongue 451 after moving to the left, it can be maintained in this position. Therefore, the unwinding disk 70 is unlocked at this time and can rotate freely.

[0039] The rotation of gear 2 53 opens the valve 52, and the high-pressure light gas, such as helium, contained in the gas cylinder 51 passes smoothly through the valve 52, passes through the rotary joint 72, the air inlet 702, the rotating shaft 701, the air outlet 703 and the hose 73, and finally rushes into the balloon 6.

[0040] At the same time, the protrusion 801 on the original limiting member 80 is stuck with the buckle 88, and the cover 33 remains in the closed state. When the rack 1 40 moves to the left and drives the limiting member 80 to move to the left, the buckle 88 disengages from the limit of the protrusion 801, and the spring 3 87 releases the pressure, causing the rack 2 81 to also move to the left. The cover opening gear 83 engaged with the rack 2 81 rotates clockwise, and the cover opening gear 83 drives the hinge shaft 82 to rotate as well. The hinge shaft 82 is fixedly connected to the cover 33, and the cover 33 can be rotated to open. The gas in the gas cylinder 51 can inflate the balloon 6 to a certain volume, and then the balloon 6 rises due to the buoyancy of the air, the hose 73 slides in the roller 71, and the unwinding disk 70 rotates freely. The hose 73 plays the role of inflating on the one hand, and on the other hand, it also plays the role of limiting the rising height of the balloon 6, so that the balloon 6 can hover in the air. Rescue vehicles in the distance can quickly find the accident area based on the balloon 6 hovering in the air. At the same time, the fluorescent layer on the surface of the balloon 6 and the hose 73 can also improve the visibility at night, so that the balloon 6 can be seen at night.

[0041] When the accident vehicle is found, the unwinding disc 70 can be rotated using the turning handle 77 to lower the balloon 6, and then the gas in the balloon 6 can be released using the air nozzle 74. The cover 33 is closed, and the key is inserted into the lock body 45. After rotation, the lock tongue 451 can be retracted to reset the rack 40. The protrusion 801 on the limit member 80 is used to re-engage the buckle 88 to complete the reset of the cover 33. The gas cylinder 51 is replaced and the device can be reused.

[0042] From the technical knowledge, it can be known that the present application can be realized by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments are only illustrative in all aspects and are not the only ones. All changes within the scope of the present application or within the equivalent scope of the present application are included in the present application.
