Description

Technical Field

[0001] This invention relates to the field of road fence technology, specifically to a movable anti-collision fence for extra-wide lanes at highway toll stations. Background Technology

[0002] Fences are generally used for decoration and simple protection. On roads, fences can separate lanes, creating clear boundaries between opposing lanes. At highway entrances, fences can also restrict oversized vehicles from entering the highway. Currently, most fences at highway toll stations are fixed. However, when transporting particularly oversized cargo, fixed fences prevent the transport vehicle from entering the highway, necessitating fence removal, thus reducing their practicality. Furthermore, most fences lack the ability to provide collision buffers for out-of-control vehicles, failing to guarantee the safety of the vehicle and its occupants in the event of a loss of control. Therefore, how to provide a fence with adjustable width and the ability to provide collision buffers for out-of-control vehicles is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] In view of this, the present invention provides a movable anti-collision fence for extra-wide lanes at highway toll stations. The present invention can adjust the width of the fence to facilitate the passage of extra-wide vehicles and provide anti-collision buffer function for out-of-control vehicles.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] See appendix Figures 1-6 This invention discloses a movable anti-collision fence 6 for extra-wide lanes at highway toll stations, comprising:

[0032] The base 1 has multiple equally spaced sliding grooves 2 at its upper end. Each sliding groove 2 is equipped with a damping slider 4, which is slidably connected to the sliding groove 2.

[0033] A power component is provided, which passes through the slide 2 and is connected to the damping slider 4 to drive the damping slider 4 to move. Preferably, the power components are arranged one-to-one on the inner side wall of the slide 2. The power components drive the damping slider 4 to slide along the slide 2 one-to-one. By moving the damping slider 4 through the power components, the position of the connecting shaft 5 is adjusted, thereby adjusting the overall position of the fence 6 to facilitate the passage of extra-wide vehicles.

[0034] Connecting shaft 5 is fixedly mounted on damping slider 4, and connecting shaft 5 and damping slider 4 are set in a one-to-one correspondence.

[0035] Fence 6, multiple fences 6 are provided, and two adjacent connecting shafts 5 are respectively connected to the two sides of the same fence 6. The fence 6 and the connecting shafts 5 are rotatably connected.

[0036] A guide assembly is rotatably mounted on the base 1; preferably, the guide assembly is located at the bottom of the fence 6. The guide assembly guides the vehicle to move along the direction of the fence 6, preventing the vehicle's kinetic energy from being completely released at the moment of impact, thus protecting the safety of the vehicle and its occupants.

[0037] A buffer assembly is fitted onto the connecting shaft 5.

[0038] In this embodiment, the power assembly specifically includes: a motor 17, a first lead screw 3, a sleeve 21, a transmission shaft 23, and a prism 22. The first lead screw 3 passes through the slide groove 2 and is arranged along the extension direction of the slide groove 2. The damping slider 4 and the first lead screw 3 are connected by threads. The other end of the first lead screw 3 is provided with a sleeve 21, which passes through the slide groove 2 and is rotatably connected to the inner wall of the slide groove 2. The other end of the first lead screw 3 is provided with a transmission shaft 23, which passes through the slide groove 2 and is rotatably connected to the inner wall of the slide groove 2. The transmission shaft 23 is connected to the motor 17 via the prism 22 at its end. The motor 17 drives the first lead screw 3 to rotate. During the rotation of the first lead screw 3, the damping slider 4 moves, adjusting the position of the connecting shaft 5, and thus adjusting the overall position of the fence 6 to facilitate the passage of extra-wide vehicles.

[0039] Preferably, the damping slider 4 has a first threaded hole that matches the first lead screw 3. The damping slider 4 is rotatably connected to the first lead screw 3 through the first threaded hole. The end of the transmission shaft 23 has a polygonal groove that matches the prism 22. The prism 22 is inserted into the polygonal groove.

[0040] In this embodiment, the buffer assembly specifically includes: a first connecting seat 11, a second connecting seat 12, a damping assembly, and an airbag 14. The first connecting seat 11 and the second connecting seat 12 are respectively disposed on opposite sides of the connecting shaft 5. One end of the airbag 14 is connected to the first connecting seat 11, and the other end of the airbag 14 is connected to the second connecting seat 12. The damping assembly is disposed on the outer side wall of the base 1 and is connected to the airbag 14.

[0041] In this embodiment, the damping assembly specifically includes: a sleeve 7, a piston 20, a connecting seat 8, and a connecting pipe 15. The sleeve 7 passes through the slide groove 2 and is threadedly connected to the first lead screw 3. The sleeve 7 and the first lead screw 3 are arranged in a one-to-one correspondence. The sleeve 7 is connected to the connecting seat 8, and the connecting seat 8 is connected to the airbag 14 through the connecting pipe 15. Preferably, the thread of the sleeve 7 is opposite to the thread of the first threaded hole of the damping slider 4, so that the sleeve 7 and the damping slider 4 move in opposite directions. The connecting pipe 15 passes through the first connecting seat 11 and is connected to the airbag 14. The second connecting seat 12 is provided with multiple small holes 13 for venting. The small holes 13 are connected to the other end of the airbag 14. The output of gas is limited by the small holes 13, so that the airbag 14 can reset at a lower speed, thereby ensuring the buffering effect. During the sliding process of the damping slider 4, the gas inside the sleeve 7 is forced into the connecting seat 8 through the sleeve rod 21 and the piston 20, and then enters the first connecting seat 11 through the connecting pipe 15, and then enters the airbag 14. When the airbag 14 collides, it provides cushioning for the vehicle when it is hit.

[0042] In this embodiment, specifically, it also includes a cover 16, a motor 17, a first chain 19, and a first sprocket. The cover 16 is sleeved on the outside of the base 1. The end of the prism 22 is provided with a first sprocket. The motor 17 is connected to the first chain 19 and the first sprocket for transmission. Preferably, the output shaft of the motor 17 is fixed to one of the transmission shafts 23. When the switch of the motor 17 is turned on, the motor 17 works, and through the transmission of the first chain 19 and the first sprocket, it drives the first lead screw 3 to rotate through the prism 22. This, in conjunction with the first threaded hole on the damping slider 4, enables the damping slider 4 to move in the slide groove 2, thereby driving the connecting shaft 5 to move.

[0043] In this embodiment, specifically, a limiting component is also included. The limiting component includes a second lead screw 24, a transmission block 25, a connecting rod 26, and a rubber block 27. The connecting shaft 5 is hollow, and multiple evenly distributed rectangular holes are formed on its sidewall. A rubber block 27 is placed inside each rectangular hole. The second lead screw 24 is rotatably mounted within the connecting shaft 5 and is connected to the guide component. The transmission block 25 and the second lead screw 24 are connected by threads. One end of the connecting rod 26 is rotatably connected to the transmission block 25, and the other end is rotatably connected to the rubber block 27. The transmission block 25 drives the rubber block 27 to slide horizontally. The components are used to increase the friction between the fence 6 and the connecting shaft 5, and the guide components and the limiting components correspond one-to-one to form a transmission fit; preferably, there are two transmission blocks 25, and the two transmission blocks 25 are rotatably connected through the second threaded hole and the second lead screw 24 on them; during the rotation of the second lead screw 24, it drives the transmission block 25 to move, and the movement of the transmission block 25 changes the angle of the connecting rod 26. The connecting rod 26 pushes the rubber block 27 to slide out of the rectangular hole, realizing a tight contact between the rubber block 27 and the fence 6, thereby increasing the friction between the connecting shaft 5 and the fence 6, converting the kinetic energy of the vehicle into the internal energy of the rubber block 27 and the fence 6, and realizing buffering.

[0044] In this embodiment, the guiding assembly specifically includes: a rotating shaft 10, a second chain 28, and guide wheels 9. Multiple rotating shafts 10 and guide wheels 9 are provided, with the multiple rotating shafts 10 evenly distributed on the lower side of the fence 6. Each rotating shaft 10 has a guide wheel 9 at its bottom. The second lead screw 24 is equipped with a second sprocket. The rotating shafts 10 are connected via the second chain 28 and the second sprocket. Preferably, multiple rotating shafts 10 are provided, equidistantly positioned at the bottom of the fence 6. Each rotating shaft 10 has a guide wheel 9 at its bottom. During the rotation of the guide wheel 9, the guide wheel 9 drives the rotating shaft 10 to rotate, which in turn drives the second lead screw 24 to rotate under the action of the second sprocket and the second chain 28.

[0045] In this embodiment, specifically, the bottom of the base 1 is provided with a plurality of evenly distributed pile foundations 18.

[0046] The specific working method is as follows:

[0047] When the position of the fence 6 needs to be adjusted, the switch of the motor 17 is turned on. When the motor 17 is working, it drives the transmission shaft 23 to rotate through the first chain 19 and the first sprocket, thereby driving the first lead screw 3 to rotate through the prism 22. In conjunction with the first threaded hole on the damping slider 4, the damping slider 4 moves in the slide groove 2, thereby driving the connecting shaft 5 to move. When all the connecting shafts 5 move synchronously, they drive the fence 6 to move and adjust the position of the fence 6, thereby enabling the passage of extra-wide cargo vehicles.

[0048] Upon impact, the vehicle comes into contact with the guide wheel 9. First, the rotation of the guide wheel 9 allows the vehicle to move along the direction of the fence 6 under the guidance of the guide wheel 9. At the same time, the impact of the vehicle causes the fence 6 at the point of impact to move horizontally.

[0049] During the rotation of the guide wheel 9, the guide wheel 9 drives the rotating shaft 10 to rotate. Under the action of the second sprocket and the second chain 28, the second lead screw 24 is driven to rotate. During the rotation of the second lead screw 24, the transmission block 25 is moved. With the action of the connecting rod 26, the rubber block 27 slides out of the rectangular hole, realizing a tight contact between the rubber block 27 and the fence 6, thereby increasing the friction between the connecting shaft 5 and the fence 6, converting the kinetic energy of the vehicle into the internal energy of the rubber block 27 and the fence 6, and realizing the first step of buffering.

[0050] The fence 6 is moved by the impact, and heat is generated by the friction between the damping slider 4 and the groove 2 to achieve the second step of buffering;

[0051] During the sliding of the damping slider 4, the first lead screw 3 is driven to rotate, and the sleeve 7 moves forward under the drive of the first lead screw 3. At this time, the gas inside the sleeve 7 is forced into the connecting seat 8 through the sleeve rod 21 and the piston 20, and then enters the first connecting seat 11 through the connecting pipe 15, and then enters the airbag 14. The airbag 14 is inflated to provide the third step of buffering for the vehicle, so that the vehicle can decelerate. Finally, the gas is output through the small hole 13 on the second connecting seat 12. The output of the gas is limited by the small hole 13, so that the airbag 14 can return to its original position at a small speed, thereby ensuring the buffering effect.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
