Description

Technical Field

[0001] This utility model relates to the field of curve protection technology, and in particular to an assembled curve protection isolation device. Background Technology

[0002] Curve protection barriers are specially designed to improve road safety, especially to provide extra protection for vehicles at curves. They can effectively absorb energy in the event of a collision, reducing injury to vehicles and passengers.

[0003] For example, a type of assembled highway rotating crash barrier with publication number CN217710474U includes a rotating cylinder with an installation shaft running through it; a lower mounting beam with a first mounting seat on it, the first mounting seat including a mounting cylinder with a rotating sleeve rotatably mounted inside; the bottom end of the installation shaft being engaged within the rotating sleeve; an ejector assembly located within the rotating sleeve and below the bottom end of the installation shaft; an upper mounting beam with a second mounting seat on it, the second mounting seat including a horizontal plate with a fixed post movably mounted on it, the bottom end of the fixed post being inserted into the upper end of the installation shaft; a stabilizing disc on the rod of the fixed post, with multiple limiting posts on the top of the stabilizing disc; and a compression spring fitted on the limiting posts to solve the problem that the rotating cylinder cannot be quickly removed from the barrier when replacing it, making the replacement of the rotating cylinder time-consuming. However, because the mounting beams of this modular highway rotating crash barrier need to be bolted to the mounting base, disassembly is inconvenient and it is difficult to adapt to the protection requirements of curves with different curvatures.

[0004] Therefore, a modular curve protection and isolation device has been developed that can quickly and easily install and fix the mounting beams, and can adjust the angle between the mounting beams to meet the protection needs of curves with different curvatures. Utility Model Content

[0005] To overcome the shortcomings of existing modular highway rotating crash barriers, which require the mounting beams to be bolted to the mounting bases, making disassembly inconvenient and difficult to adapt to the protection requirements of curves with different curvatures, this utility model provides a modular curve protection and isolation device that can quickly and easily install and fix the mounting beams, and can adjust the angle between the mounting beams to meet the protection requirements of curves with different curvatures.

[0006] The technical solution is as follows: A modular curve protection and isolation device includes an installation rod, an installation sleeve, a rotating barrel, an extrusion block, an installation beam, a fixing component, an assembly component, and a limiting component. The installation sleeve is slidably and detachably connected to the installation rod. The rotating barrel is rotatably connected to both the upper and lower parts of the installation sleeve. Two extrusion blocks are connected to both the upper and lower parts of the installation sleeve. Two installation beams are snapped onto both the upper and lower sides of the installation sleeve. The installation beams are provided with fixing components that can be fixed to the installation sleeve. The installation beams are also provided with assembly components that can be assembled with each other. The assembly components are provided with limiting components that can fix the angle between the installation beams.

[0007] Preferably, the mounting rod has multiple mounting holes on its underside.

[0008] Preferably, the fixing component includes a limiting frame and a first telescopic spring. The limiting frame is slidably connected to the middle of the mounting beam. The pressing block is pressed and engaged with the limiting frame. The limiting frame is connected to the mounting beam by two left and right first telescopic springs.

[0009] Preferably, the assembly includes a mounting cylinder, a connecting block, a fixing frame, and a second telescopic spring. The mounting beam is rotatably connected to the mounting cylinder on both the left and right sides. A connecting block is snapped onto the mounting cylinder on the left side. The connecting block is slidably connected to two fixing frames on both the left and right sides. The fixing frames are snapped into the adjacent mounting cylinders. A second telescopic spring is connected between the fixing frames and the connecting blocks they are connected to.

[0010] Preferably, the limiting component includes gears, limit frames, and a third telescopic spring. Gears are connected to the upper part of the mounting cylinder, and limit frames are slidably connected to both sides of the mounting beam. Each limit frame engages with the adjacent gear, and a third telescopic spring connects each limit frame to the connected mounting beam.

[0011] As a preferred option, each limit frame is equipped with a pull block.

[0012] Beneficial effects: 1. This utility model uses the squeezing block to squeeze the limiting frame inward, so that the limiting frame and the mounting sleeve are engaged and fixed on the mounting sleeve. Then, the connecting block is inserted between the two adjacent mounting cylinders on the left and right. When the fixing frame is released, the second telescopic spring rebounds, so that the fixing frame is reset and engaged with the connecting block, thus fixing the connecting block. This achieves the effect of quickly and conveniently installing and fixing the mounting beam.

[0013] 2. This utility model achieves the effect of adjusting the angle between the mounting beams by pulling the limiting frame outward to disengage from the gear, compressing and contracting the third telescopic spring, and then rotating the mounting cylinder to adjust the angle of the connecting block, so as to meet the protection requirements of different curvature curves.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] A modular curve protection and isolation device, such as Figures 1-6 As shown, it includes an installation rod 1, an installation sleeve 2, a rotating barrel 3, an extrusion block 4, an installation beam 5, a fixing component, an assembly component, and a limiting component. The installation sleeve 2 is slidably and detachably connected to the installation rod 1. The installation rod 1 has four installation holes on its lower side for easy installation and fixing. The rotating barrel 3 is rotatably connected to both the upper and lower parts of the installation sleeve 2. The upper and lower parts of the installation sleeve 2 are connected to two front and rear extrusion blocks 4. The upper and lower sides of the installation sleeve 2 are clamped to two front and rear installation beams 5. The installation beams 5 are equipped with fixing components and assembly components. The assembly components are equipped with limiting components.

[0023] like Figure 1 and Figure 4 As shown, the fixing component includes a limiting frame 6 and a first telescopic spring 7. The limiting frame 6 is slidably connected to the middle of the mounting beam 5. The pressing block 4 is pressed and engaged with the limiting frame 6. The limiting frame 6 is connected to the mounting beam 5 by two left and right first telescopic springs 7.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, the assembly includes a mounting cylinder 8, a connecting block 9, a fixing frame 10, and a second telescopic spring 11. The mounting beam 5 is rotatably connected to the mounting cylinder 8 on both the left and right sides. The mounting cylinder 8 on the left side is snapped with a connecting block 9. The connecting block 9 is slidably connected to two fixing frames 10 on both the left and right sides. The fixing frames 10 are snapped into the adjacent mounting cylinder 8. The fixing frames 10 are connected to the connecting blocks 9 with the second telescopic spring 11.

[0025] like Figure 1 and Figure 6 As shown, the limiting components include gears 12, limit frames 13, and third telescopic springs 14. Gears 12 are connected to the upper part of the mounting cylinder 8. Limit frames 13 are slidably connected to the left and right sides of the mounting beam 5. Each limit frame 13 is equipped with a pull block for easy pulling. Each limit frame 13 is engaged with the adjacent gear 12. Each limit frame 13 is connected to the mounting beam 5 with a third telescopic spring 14.

[0026] When using this utility model, firstly, according to the length of the curve, install the corresponding number of mounting rods 1 on the edge of the curve, then place two mounting beams 5 at the lower part of the mounting rods 1, then insert the mounting sleeve 2 into the mounting rods 1, and then place the two mounting beams 5 on the upper side of the mounting sleeve 2. The limiting frame 6 is pressed inward by the pressing block 4, and the first telescopic spring 7 is stretched, so that the limiting frame 6 and the mounting sleeve 2 are engaged and fixed on the mounting beam 5 on the mounting sleeve 2.

[0027] Then, the fixing bracket 10 is pressed inward, the second telescopic spring 11 is compressed and contracted, and the connecting block 9 is then inserted between the two adjacent mounting cylinders 8. Then the fixing bracket 10 is released, the second telescopic spring 11 rebounds, so that the fixing bracket 10 returns to its original position and engages with the connecting block 9, fixing the connecting block 9 between the two adjacent mounting cylinders 8. Then the mounting beam 5 is horizontally spliced ​​to protect the curve from collision, thus achieving the function of quickly and conveniently installing and fixing the mounting beam 5. When the vehicle hits the rotating barrel 3, the rotating barrel 3 rotates, dispersing the impact force of the vehicle.

[0028] When installing the connecting block 9, the limiting frame 13 can be pulled outward to disengage from the gear 12 according to the curvature of the curve. The third telescopic spring 14 is compressed and contracted. Then, the mounting cylinder 8 is rotated to adjust the angle of the connecting block 9, thereby adjusting the angle between the mounting beams 5 to meet the protection requirements of curves with different curvatures. After adjustment, the limiting frame 13 is released, and the third telescopic spring 14 rebounds, causing the limiting frame 13 to reset the fixing wheel 12 and the mounting cylinder 8.
