The flexible barrier belt is made of high-strength fiber material, and a plurality of horizontal tie steel ropes and vertical tie steel ropes are fixedly connected to the surface of the flexible barrier belt. One end of each of the plurality of horizontal tie steel ropes is wound and fixed to the winding shaft. The horizontal and vertical tie ropes intersect perpendicularly to form a grid structure. The end of the flexible enclosure strip away from the rewind shaft is fixedly connected to a hook rod. Both ends of the hook rod protrude from the upper and lower sides of the flexible enclosure strip. The storage tube has an outlet on one side, through which the flexible enclosure strip passes through the outlet and exits the outside of the fixed floor. The top and bottom of the storage tube away from the outlet are fixedly connected to fixing hooks. The two fixing hooks can be hooked and fixed to the two ends of the hook rod respectively. A coil spring is provided at the bottom of the rewind shaft. The center of the coil spring is fixedly connected to the rewind shaft, and the outer side of the coil spring is fixedly connected to the inner wall of the storage tube.
[0006] Preferably, in any of the above embodiments, a guide prism is fixedly connected to the top of the winding shaft, a baffle is fixedly connected to the top of the guide prism, an inner ratchet ring is fixedly connected to the top surface of the storage cylinder, and an eccentric ratchet is slidably connected to the outer wall of the guide prism, the eccentric ratchet being able to engage and be fixed with the inner ratchet ring.
[0007] The technical effect achieved by adopting the above solution is that the ratchet ring slides along the guide strip through hole, so that one side of the eccentric ratchet hits the inner ratchet ring, thereby locking and achieving timely stopping.
[0008] Preferably, in any of the above embodiments, the eccentric ratchet has a guide strip-shaped through hole in the middle, the guide strip-shaped through hole is horizontally slidably connected to the guide prism, and a return spring is fixedly connected between the middle of one side of the inner wall of the guide strip-shaped through hole and the middle of one side of the guide prism.
[0009] The technical effect achieved by adopting the above solution is that the eccentric ratchet can be pushed to reset by the return spring, so that the eccentric ratchet remains stable under normal pulling low speed.
[0010] Preferably, in any of the above embodiments, when the return spring is reset, the eccentric ratchet is pulled to the middle of the inner wall of the inner ratchet ring and disengages from the ratchet teeth on the inner wall of the inner ratchet ring, and when the return spring is reset, the center of the eccentric ratchet is on the side away from the return spring.
[0011] The technical effect achieved by the above solution is that when the eccentric ratchet rotates, it slides away from the return spring, thus achieving eccentric sliding engagement.
[0012] Preferably, in any of the above embodiments, the length of the hook-and-pull rod is greater than the length of the through-hole, the hook-and-pull rod is made of iron, and a magnet is fixedly connected to the inner wall of the fixing hook.
[0013] The technical effect achieved by adopting the above solution is that the hook-and-pull rod is blocked outside the outlet, making it easy to pull. The magnetic attraction can improve the stability of the fixation and prevent detachment.
[0014] This utility model has the following advantages:

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0024] like Figures 1 to 5As shown, a safety barrier for highway asphalt pavement construction includes a fixed floor 1. A storage cylinder 2 is fixedly connected to the center of the top surface of the fixed floor 1. A winding shaft 17 is rotatably connected to the center of the inner wall of the storage cylinder 2. Positioning baffles 15 are fixedly connected to both the upper and lower sides of the winding shaft 17. The winding shaft 17 is positioned between the two positioning baffles 15 and is fixedly connected to a flexible barrier belt 4. The flexible barrier belt 4 is made of high-strength fiber material. Several horizontal tie steel ropes 5 and vertical tie steel ropes 6 are fixedly connected to the surface of the flexible barrier belt 4. One end of each horizontal tie steel rope 5 is wound and fixed to the winding shaft 17. The steel ropes 6 are intersecting perpendicularly to form a grid structure. The end of the flexible enclosure belt 4 away from the winding shaft 17 is fixedly connected to a hook rod 7. Both ends of the hook rod 7 protrude from the upper and lower sides of the flexible enclosure belt 4. The storage tube 2 has an outlet 3 on one side. The flexible enclosure belt 4 passes through the outlet 3 and exits the outside of the fixed floor 1. The top and bottom of the storage tube 2 away from the outlet 3 are fixedly connected to fixing hooks 9. The two fixing hooks 9 can be hooked and fixed to the two ends of the hook rod 7 respectively. The bottom of the winding shaft 17 is provided with a coil spring 16. The center of the coil spring 16 is fixedly connected to the winding shaft 17, and the outer side of the coil spring 16 is fixedly connected to the inner wall of the storage tube 2.
[0025] As an optional technical solution of this utility model: a guide prism 10 is fixedly connected to the top of the take-up shaft 17, a baffle 13 is fixedly connected to the top of the guide prism 10, an inner ratchet ring 8 is fixedly connected to the top surface of the storage cylinder 2, and an eccentric ratchet 11 is slidably connected to the outer wall of the guide prism 10. The eccentric ratchet 11 can engage and fix with the inner ratchet ring 8. When the vehicle crashes, the take-up shaft 17 quickly unwinds and rotates, driving the guide prism 10 and the eccentric ratchet 11 to rotate, generating centrifugal force that causes the ratchet ring 8 to slide along the guide strip through hole 12, so that one side of the eccentric ratchet 11 hits the inner ratchet ring 8, thereby locking and achieving timely stopping.
[0026] As an optional technical solution of this utility model: the eccentric ratchet 11 has a guide strip-shaped through hole 12 in the middle, the guide strip-shaped through hole 12 is horizontally slidably connected to the guide prism 10, and a return spring 14 is fixedly connected between the middle of one side of the inner wall of the guide strip-shaped through hole 12 and the middle of one side of the guide prism 10. The return spring 14 can push the eccentric ratchet 11 to return to its original position, so that the eccentric ratchet 11 remains stable under normal low speed.
[0027] As an optional technical solution of this utility model: when the return spring 14 is reset, the eccentric ratchet 11 is pulled to the middle of the inner wall of the inner ratchet ring 8 and disengages from the ratchet teeth of the inner wall of the inner ratchet ring 8. When the return spring 14 is reset, the center of the eccentric ratchet 11 is on the side away from the return spring 14, so that when the eccentric ratchet 11 rotates, it slides to the side away from the return spring 14, thereby realizing eccentric sliding engagement.
[0028] As an optional technical solution of this utility model: the length of the hooking rod 7 is greater than the length of the outlet 3. The hooking rod 7 is made of iron. The inner wall of the fixing hook 9 is fixedly connected with a magnet, so that the hooking rod 7 is blocked outside the outlet 3, making it easy to pull. The magnetic attraction can improve the stability of the fixation and prevent detachment.
[0029] The working process of this utility model is as follows: When the user uses it...
[0030] 1) By installing and fixing several storage cylinders 2 at the corresponding distance to the edge of the construction site, and then pulling the hook rod 7 to hook it onto the fixing hook 9 on the outer wall of the adjacent storage cylinder 2, the flexible enclosure belt 4 can be pulled out to cover the position between the two storage cylinders 2, thus forming an enclosure.
[0031] 2) When disassembling, pull out the hook rod 7, and the flexible enclosure belt 4 can be automatically rolled back by the coil spring 16, which is convenient for recycling and improves efficiency;
[0032] 3) When setting up, the flexible barrier 4 should be reserved with a certain length for winding. Then, when a vehicle crashes into it, it should have a certain length to be pulled out, thus forming a buffer distance to buffer the vehicle. At the same time, the flexible material and the structure of several horizontal tie steel ropes 5 and vertical tie steel ropes 6 are reinforced to prevent rigid contact from causing excessive damage to vehicles and personnel while blocking the vehicle.
[0033] 4) When the vehicle crashes, the winding shaft 17 is rapidly unwound and rotated, which drives the guide prism 10 and the eccentric ratchet 11 to rotate. This generates centrifugal force, causing the ratchet ring 8 to slide along the guide strip through hole 12. This causes one side of the eccentric ratchet 11 to push against the inner ratchet ring 8, thereby locking it and achieving timely stopping.
[0034] In summary, this utility model, by installing and fixing several storage cylinders 2 at corresponding distances to the edge of the construction site, and then pulling the hook rod 7 to hook it onto the fixing hook 9 on the outer wall of the adjacent storage cylinder 2, allows the flexible barrier belt 4 to be pulled out to cover the area between two storage cylinders 2, forming a barrier. Installation is convenient, simple, and quick. During disassembly, pulling out the hook rod 7 allows the flexible barrier belt 4 to be automatically rolled back by the coil spring 16, facilitating retrieval and improving efficiency. During erection, a certain length of the flexible barrier belt 4 is reserved for winding, so that it has a certain length to extend in the event of a vehicle collision, thus creating a buffer distance and cushioning the vehicle. Simultaneously, the flexible material and the reinforced structure of several horizontal and vertical tie steel ropes 5 and 6, while restraining vehicles, prevent excessive damage to vehicles and personnel from rigid contact, improving safety.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
