Description

Technical Field

[0001] The present invention relates to the technical field of isolation guardrails, and specifically, to a safety isolation device for highway reconstruction and expansion construction. Background Art

[0002] When repairing, reconstructing or expanding a road or highway, an isolation device is required to isolate the road surface and guide the traffic flow. The methods adopted in the prior art are to place isolation warning signs, warning piers or pull-type isolation guardrails. When using warning signs and warning piers, the entire isolation is not continuous, and there are still certain potential safety hazards in construction safety. At the same time, due to the wind, the isolation piers and warning signs are prone to displacement. Similarly, for the isolation guardrail, since its bottom is not fixed and is set on the road surface by means of rollers, it is also interfered by problems such as wind or the air flow driven by vehicles, and is prone to displacement, with poor isolation effect and certain safety problems. Moreover, the functions of the existing isolation guardrails are relatively single. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] As Figures 1 - 4 shown, this embodiment proposes a safety isolation device for highway reconstruction and expansion construction, which includes a plurality of isolation units 200 rotatably connected through a steering collar 100. By pulling the isolation unit 200, the device can be unfolded, and at the same time, the device can be enclosed according to the construction site. A connected fixed water supply mechanism 300 is provided at the lower part of the plurality of isolation units 200 in this embodiment. A folding isolation mechanism 400 is arranged in the isolation unit 200, and the folding isolation mechanism 400 is drivingly connected to a bottom protection mechanism 600 and an upper isolation indication mechanism 700 through a linkage mechanism 500.

[0036] The principle of this embodiment is as follows: The plurality of isolation units 200 are connected through the steering collar 100, so that the isolation units 200 can rotate relative to each other, which is convenient for enclosing the device according to the construction site. The fixed water supply mechanism 300 can, on the one hand, fix the bottom of the device by using the weight of water, and on the other hand, supply water to the inside of the construction site, killing two birds with one stone. At the same time, when pulling the device, during the unfolding process of the folding isolation mechanism 400, the bottom protection mechanism 600 can be driven to act through the linkage mechanism 500. On the one hand, it protects the fixed water supply mechanism 300, and on the other hand, it can abut against the ground, further improving the bottom fixing strength of the device, enhancing the protection effect, and at the same time driving the upper isolation indication mechanism 700 to unfold to form an indication mark for warning vehicles and the like.

[0037] See Figure 1 and Figure 2 , in this embodiment, the isolation unit 200 includes two support frames 210. The support frames 210 can be made of lightweight steel. A roller 220 is provided at the bottom of the support frame 210. The folding isolation mechanism 400 is arranged between the two support frames 210. The support frames 210 of two adjacent isolation units 200 are connected through a plurality of steering collars 100. By pulling the support frame 210, it is convenient to unfold the device. The rollers 220 at the bottom are convenient for pulling. Connecting the two support frames 210 through the steering collar 100 is convenient for the adjacent isolation units 200 to rotate relative to each other and enclose the device according to the construction site conditions.

[0038] On opposite sides of the support frame 210, there are sliding grooves 230. Inside the sliding grooves 230, there are upper hinge ears 240 and lower hinge ears 250 slidingly arranged. The folding isolation mechanism 400 includes a plurality of folding rods 410 hinged to each other in the middle. The ends of two folding rods 410 near the side of the support frame 210 are respectively rotatably connected to the upper hinge ear 240 and the lower hinge ear 250, and the ends of the remaining folding rods 410 are hinged to each other. The upper hinge ear 240 and the lower hinge ear 250 can slide inside the sliding grooves 230, facilitating the mutual rotation and deployment of the folding rods 410 to form a guardrail.

[0039] In this embodiment, the fixed water supply mechanism 300 includes a flexible water hose 310 arranged at the lower part of the isolation unit 200. The bottom protection mechanism 600 is arranged outside the flexible water hose 310. Inside the flexible water hose 310, there are several quick-connect fittings 320 with valves.

One end of the flexible water hose 310 can be a blind end, and the other end can be connected to a sprinkler truck or the like. By filling water into it, the bottom of this device can be fixed. At the same time, on the side facing the construction site, there are quick-connect fittings 320. By connecting a water pipe, water can be provided to the construction site, saving the process of the sprinkler truck running back and forth, achieving two purposes at once of supplying water and fixing this device.

[0040] Referring to Figure 1 and Figure 3 , in this embodiment, the bottom protection mechanism 600 includes a plurality of protection plates 620 hinged to the lower parts of two folding rods 410 through torsion shafts 610. The protection plates 620 are staggered from each other. The protection plates 620 can protect the flexible water hose 310 and can be abutted against the ground to form a fixed support under the drive of the linkage mechanism 500, improving the fixing effect of this device. The staggered arrangement of the protection plates 620 facilitates the folding, retracting, and storing of this device after the construction is completed.

[0041] In this embodiment, the linkage mechanism 500 includes a top contact component for top contacting the protection plate 620. The top contact component is arranged between the protection plate 620 and the folding rod 410.

The top contact component is used to top contact the protection plate 620 so that the lower end of the protection plate 620 abuts against the ground to form a support, and the support component is used to support the upper isolation indication mechanism 700.

[0042] The top connection component therein includes a driven inclined block 510 provided on the upper side of the protection plate 620 and a top connection rod 520 provided on the folding rod 410, wherein the top connection rod 520 is a telescopic rod. When pulling the support frame 210 to unfold each folding rod 410, the folding rod 410 moves to one side, driving the top connection rod 520 to move. The lower end of the top connection rod 520 abuts on the driven inclined block 510, pushing the protection plate 620 to abut on the road surface to form protection and support.

[0043] The upper isolation indication mechanism 700 in this embodiment includes an isolation net 710, and fluorescent indication marks are provided on the isolation net 710. The support component includes a support rod 530 fixedly provided at the upper end of the folding rod 410. The isolation net 710 is fixed on the support frame 210 and the support rod 530. When the folding rod 410 unfolds, it drives the support rod 530 to unfold, and the support rod 530 can drive the isolation net 710 to unfold. The fluorescent indication marks unfold to prompt vehicles and guide the traffic flow.

[0044] Refer to Figure 4 In order to improve the accuracy of the top connection, a top connection block 540 cooperating with the driven inclined block 510 is provided at the lower end of the top connection rod 520 in this embodiment. By providing the top connection block 540, a larger contact area with the driven inclined block 510 can be formed for the top connection.

[0045] In order to improve the warning effect at night, a warning lamp 720 is further provided at the upper end of the support rod 530. By providing the warning lamp 720, an effective warning can be formed at night.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
