Description
Technical Field
[0001] This utility model relates to the field of highway protection facilities technology, and in particular to an emergency control device for highway subgrade slope collapse. Background Technology
[0002] Currently, emergency response to highway slope hazards is largely passive, relying on early warning systems. Monitoring and early warning systems are installed near sections of highway prone to collapse or rockfalls. When a hazard occurs, warning signs are displayed on LED screens, audible announcements are made via loudspeakers, and red and blue flashing warning lights alert vehicles. However, due to the diverse terrain and complex geological conditions of highways, especially in mountainous areas, rockfalls and slope collapses are often caused by continuous heavy rainfall. This persistent downpour leads to instability in the communication and power supply systems of the monitoring and early warning systems, resulting in delayed responses and ultimately compromising the stability and reliability of the emergency response mechanisms.
[0003] To further improve the stability and reliability of highway slope early warning systems and enhance the efficiency of early warning response, enabling immediate vehicle control when slope risks and hazards arise, it is necessary to design an emergency control device for highway subgrade slope collapse. This device should be able to respond quickly and issue early warnings when slope collapses, rockfalls, or other incidents cause damage to the highway. Through a self-activating protective device, traffic control can be implemented, addressing the problems of current electronic monitoring and early warning methods, minimizing the probability of secondary accidents, reducing losses caused by slope collapses, and filling the gap in the rapid response and control technology system for highway subgrade slope collapses. Utility Model Content
[0004] The technical problem to be solved by this utility model is to improve the early warning response efficiency of highway slopes and to control vehicles as soon as possible when risks and hidden dangers appear on the slopes. A new emergency control device for highway subgrade slope collapse is proposed.
[0005] The emergency control equipment for roadbed slope collapse includes: protective netting, two magnetic suction devices, two steel wire ropes (first and second), two combined pulley blocks, and two mechanical barrier gates.
[0006] The protective netting is installed along the edge of the roadside slope at risk of disaster, with combined pulley blocks installed at both ends of the netting on the side closest to the road.
[0007] Two mechanical barrier gates are installed upstream of the two-way lanes in the disaster-risk section of the road;
[0008] One end of the steel wire rope is connected to the sliding rack in the mechanical barrier gate on the left side of the protective net, and the other end is connected to the magnetic attraction device. The other end of the magnetic attraction device is connected to the second steel wire rope. The second steel wire rope passes through the combined pulley system, then through the combined pulley system on the right side of the protective net, and is connected to the magnetic attraction device on the right side of the protective net. The magnetic attraction device on the right side is connected to the sliding rack in the mechanical barrier gate on the right side of the protective net through another steel wire rope.
[0009] In a preferred embodiment of this solution, the combined pulley block includes a height-adjustable bracket fixed to the ground. A pulley box is fixedly installed on the height-adjustable bracket. Multiple supports are fixedly installed inside the pulley box. A pulley block is installed on each support. Both sides of the pulley box have openings to accommodate the passage of a second steel wire rope. The second steel wire rope passes through the opening on the left side, passes around the multiple pulley blocks in sequence, and exits through the opening on the right side.
[0010] In a preferred embodiment of this solution, the magnetic suction device includes an iron plate and a magnetic lifting ring suction cup magnetically attached to the iron plate. The hook of the magnetic lifting ring suction cup is connected to a second steel wire rope, and the iron plate is connected to a first steel wire rope.
[0011] In a preferred embodiment of this solution, the mechanical barrier gate includes: a lower bearing support, a steering rod mounted on the lower bearing support, a gear mounted on the steering rod, the gear meshing with a rack, the rack being connected to a mass block via a steel wire rope, the rack being mounted on a slide rail and slider assembly, the slide rail and slider assembly being mounted on a support plate, a pulley support, an adjustable damper, and an upper bearing mounting plate being mounted on the support plate, an upper bearing being mounted on the upper bearing mounting plate, the upper bearing being connected to the steering rod, and an anti-collision barrier gate crossbar assembly being horizontally mounted on the upper part of the steering rod.
[0012] Furthermore, the anti-collision barrier gate crossbar assembly includes a crossbar, one end of which is connected to the upper part of the steering rod, and the other end is equipped with a rolling support foot. A solar warning light is installed on the crossbar, and a red and white safety reflective strip is affixed to the surface of the crossbar.
[0013] Furthermore, the mechanical barrier gate also includes a box body, which is fixed to the ground. The top of the box body has an L-shaped opening, and the lower bearing support and support plate are fixedly installed inside the box body. The crossbar passes through the L-shaped opening and extends outward.
[0014] Implementing this utility model has the following beneficial effects:
[0015] This emergency control equipment for roadbed slope collapse adopts a mechanical transmission method, requiring no driving power supply, resulting in higher operational reliability. It takes proactive measures to restrict traffic, and compared to methods such as "prompt messages, warning lights, alarms, and early warning information push," this control equipment is more intuitive, direct, and efficient.
[0016] This emergency control equipment for roadbed slope collapse can flexibly adjust the direction of the barrier arm according to the characteristics of the road terrain and the elevation, so that the horizontal bar rotates more smoothly after the device is activated, ensuring the adaptability of the device on site; the adaptability of nighttime early warning is enhanced by installing solar warning lights and red and white safety warning reflective strips on the horizontal bar.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1 , Figure 1 This utility model provides a schematic diagram of the installation structure of an emergency control device for highway subgrade slope collapse. The emergency control device includes: a protective net 1, two magnetic suction devices 3, two steel wire ropes 4, two steel wire ropes 6, two combined pulley blocks 2, and two mechanical barrier gates 5.
[0028] Protective netting 1 is installed along the edge of a roadside section at risk of roadside slope disasters, with combined pulley blocks 2 installed at both ends of the netting on the side closest to the road.
[0029] Two mechanical barrier gates 5 are installed upstream of the two-way lanes in the disaster-risk section of the road;
[0030] One end of wire rope 4 is connected to the sliding rack in the mechanical barrier gate 5 on the left side of the protective net 1, and the other end is connected to the magnetic attraction device 3. The other end of the magnetic attraction device 3 is connected to wire rope 6. Wire rope 6 passes through the combined pulley group 2, and then through the combined pulley group 2 on the right side of the protective net 1, and is connected to the magnetic attraction device 3 on the right side of the protective net 1. The magnetic attraction device 3 on the right side is connected to the sliding rack in the mechanical barrier gate 5 on the right side of the protective net 1 through another wire rope 4.
[0031] Specifically, please see Figure 2 , Figure 2 This is a schematic diagram of a combined pulley block. The combined pulley block 2 includes a height-adjustable bracket 7 fixed to the ground. A pulley box 8 is fixedly mounted on the height-adjustable bracket 7. Multiple supports 9 are fixedly mounted inside the pulley box 8, and pulley blocks 10 are mounted on the supports 9. Both sides of the pulley box 8 have openings to allow steel wire ropes 6 to pass through. The steel wire rope 6 enters through the left opening, passes through the multiple pulley blocks 10 sequentially, and exits through the right opening. The pulley blocks 10 are used to support and tension the steel wire ropes. The bracket adopts a modular design, allowing the height of the pulley block bracket to be adjusted according to the elevation difference of the road surface, changing the direction of force on the steel wire rope and ensuring smooth operation during triggering. The steel wire rope acts as a force transmitter, connecting the protective net, magnetic attraction device, and mechanical barrier gate equipment via the pulleys. In a balanced working state, the steel wire rope is under tension.
[0032] The magnetic suction device 3 includes an iron plate and a magnetic lifting ring suction cup that magnetically attaches to the iron plate. The lifting buckle of the magnetic lifting ring suction cup is connected to steel wire rope 6, and the iron plate is connected to steel wire rope 4. The magnetic suction device 3 is an existing technology device, and different models can be purchased and installed according to site requirements. The magnetic suction device serves as a disconnection trigger point in the emergency control equipment system. When the protective netting undergoes severe deformation or collapse, the steel wire rope bears a very large tensile force, causing the connection point of the magnetic suction device to disconnect, triggering the mechanical barrier gate device to start. The force on the magnetic suction device can be adjusted according to the application site, making it more adaptable to different situations.
[0033] Please see Figure 3-6 , Figure 3 This is a schematic diagram of a mechanical barrier gate. Figure 4 This is a schematic diagram of the internal structure of a mechanical barrier gate. Figure 5 This is a top view schematic diagram of a mechanical barrier gate. Figure 6 This is a side view of the mechanical barrier gate structure. The mechanical barrier gate 5 includes: a lower bearing support 11, a steering rod 12 mounted on the lower bearing support 11, a gear 13 mounted on the steering rod 12, the gear 13 meshing with a rack 14, and the rack 14 connected to a mass block 16 after passing over a pulley on a pulley support 19 via a steel wire rope 15. The rack 14 is mounted on a slide rail and slider assembly 17, which is mounted on a support plate 18. The support plate 18 is equipped with a pulley support 19, an adjustable damper 20, and an upper bearing mounting plate 21. An upper bearing 22 is mounted on the upper bearing mounting plate 21 and is connected to the steering rod 12. A collision-resistant barrier gate crossbar assembly is horizontally mounted on the upper part of the steering rod 12.
[0034] Specifically, the anti-collision barrier arm assembly includes a crossbar 23, one end of which is connected to the upper part of the steering rod 12, and the other end is equipped with a rolling support foot 24. A solar warning light 25 is installed on the crossbar 23, and a strong red and white safety reflective strip is affixed to the surface of the crossbar 23.
[0035] In addition, the mechanical barrier gate 5 also includes a box 26, which is fixed to the ground. The top of the box 26 has an L-shaped opening. The lower bearing support 11 and the support plate 18 are fixedly installed inside the box 26. The crossbar 23 passes through the L-shaped opening and extends outward.
[0036] In this emergency control system for roadbed slope collapses, the protective netting provides primary protection, capable of withstanding a certain amount of impact and preventing falling rocks and mudslides from slid onto the road and causing safety hazards. However, when the impact of falling rocks or slope collapse is significant, causing severe deformation or collapse of the protective netting, this situation can pose a serious threat to road vehicles. In this case, the protective netting disconnects the magnetic connection between the steel wire rope and the mechanical barrier gate, triggering the mechanical barrier gate to operate and actively restrict vehicle passage.
[0037] The mechanical barrier gate system is tensioned and connected to a magnetic attraction device near the protective netting via steel wire ropes. In its non-operating state, it achieves a state of mechanical equilibrium, with the barrier gate's crossbar parallel to the road. When the protective netting triggers the magnetic attraction device to disengage, this mechanical equilibrium is broken, causing a mass block to fall and driving a rack in linear motion. This drives a gear to rotate a steering rod, causing the crossbar to rotate as well. At the end of the rack's sliding stroke, the rotation angle reaches 90 degrees, at which point the crossbar is perpendicular to the road, effectively intercepting traffic. An upper bearing mounting plate and upper bearing prevent the rotating rod from shifting or misaligning, thus avoiding swaying during rotation. An adjustable damper is installed on the support plate near the rack slider, contacting it during operation to mitigate the inertial force generated by the barrier gate's rotation. Solar-powered warning lights and red / white safety reflective strips installed on the crossbar enhance visibility at night and provide warning information, effectively improving road safety. Racks can be installed on both sides of the support plate; by adjusting the mirrored installation position of the support plate, the barrier gate can be rotated in both directions. The anti-collision barrier gate's crossbar features anti-collision safety protection measures. The crossbar is covered with protective cotton, and the end-mounted fixings have anti-collision functions. When subjected to a certain lateral impact force, the crossbar will turn in the direction of impact, completely preventing vehicles from colliding with the crossbar and causing vehicle damage or secondary traffic accidents. Furthermore, after the mechanical barrier gate equipment is activated, the crossbar can still be used, saving maintenance costs. The housing has a groove at one end, sealed with a flexible material. The crossbar's rotation does not affect its operation, and the housing protects the internal mechanical structure, facilitating future maintenance and extending its service life.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
