Description

Technical Field

[0001] This utility model relates to the field of highway construction safety technology, specifically to a highway construction safety guidance device. Background Technology

[0002] Highway construction refers to a series of activities that involve building highways according to design requirements and technical specifications. This includes the construction of structures such as roadbeds, pavements, bridges, and tunnels, as well as the installation of ancillary facilities. The purpose of highway construction is to establish a safe, efficient, and durable transportation network to promote economic exchange and the flow of people between regions. Highway construction safety guidance devices are equipment specifically designed to improve safety during highway construction.

[0003] Currently, existing highway construction safety guidance devices have several defects. First, their structural design is rigid, with the vast majority using fixed, rigid connections. These devices cannot absorb impact energy through deformation when hit by a vehicle, nor do they have collapsible buffer structures, causing the impact force to be directly transmitted to the device's base, which can easily lead to structural damage. Second, they lack dynamic avoidance mechanisms. When a vehicle impacts the device, it cannot change the direction of force by rotating, tilting, or displacing, nor can it achieve modular disassembly to guide the vehicle safely through. Instead, the rigid obstruction may exacerbate the accident. Utility Model Content

[0004] The purpose of this utility model is to provide a highway construction safety guidance device to solve the problems of existing highway construction safety guidance devices, which adopt a fixed rigid connection structure and lack a dynamic avoidance mechanism, resulting in no buffer structure. When impacted, the structure is easily damaged due to the direct transmission of impact force. At the same time, when a vehicle impacts, the force cannot be reasonably changed or the vehicle cannot be guided through, which can easily aggravate the accident hazards.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a highway construction safety guidance device, including a base plate, a support plate movably connected to the upper end of the base plate via a hinge shaft, an inclined plate hinged to one side of the support plate via a rotating shaft, the bottom end of the inclined plate being locked with the base plate, a guide sign display frame detachably connected to the top of the other side of the support plate, a buffer plate with a limiting slide rail provided at the bottom of the support plate on one side of the guide sign display frame, and a switch assembly for controlling the locking state of the inclined plate inside the base plate, the switch assembly being drivenly connected to the buffer plate via a linkage mechanism.

[0006] The working principle of this utility model is as follows: a highway construction safety guidance device. When the device is hit by a vehicle, the vehicle first hits the buffer plate, and the impact force is transmitted to the support plate through the buffer plate. At the same time, the buffer plate controls the opening of the inclined plate's switch assembly through the linkage mechanism. At this time, the inclined plate is released from restraint and slides rapidly under the action of impact inertia. The hinge point between the support plate and the base plate loses the oblique support force. Under the action of gravity, the support plate tilts in the direction of impact with the hinge axis as the center. The buffer plate and the guide sign display frame overturn as a whole with the support plate.

[0007] The beneficial effects of this utility model are as follows: the support plate and the base plate are movably connected by a hinge shaft, and combined with the limiting snap-fit ​​structure of the inclined plate and the base plate, the limitations of the traditional fixed rigid connection are broken. When the device is impacted, the support plate can rotate around the hinge shaft, providing a basis for subsequent buffering and avoidance actions. The guide sign display frame adopts a detachable connection method, which makes it easy to flexibly change the guide information according to the construction scenario, improving the practicality of the device. The cooperation between the buffer plate, the linkage mechanism, and the switch assembly establishes an impact response mechanism. When the buffer plate is subjected to force, the linkage mechanism triggers the switch assembly to change the snap-fit ​​state of the inclined plate, allowing the vehicle to avoid the impact.

[0008] Option 2, a preferred embodiment of the basic scheme, features a longitudinally extending groove on the upper surface of the base plate. The bottom end of the inclined plate is slidably connected to the groove. Symmetrical slots are formed on both sides of the bottom end of the inclined plate. L-shaped circular grooves are formed on both sides of the inner wall of the groove corresponding to the slots. The switch assembly is integrated into the L-shaped circular groove and selectively engages with the slot. The cooperation between the slot at the bottom of the inclined plate and the switch assembly within the L-shaped circular groove on the inner wall of the groove enables stable engagement and flexible unlocking of the inclined plate at specific positions. This ensures both structural stability during normal use and provides protection for attitude adjustment under impact.

[0009] Option 3, a preferred embodiment of Option 2, includes a locking lever and a receiving plate. The locking lever is slidably connected within an L-shaped groove, with one end of the lever engaging with the groove. A fixing block is fixedly connected within the L-shaped groove, and a first spring is provided between the fixing block and the locking lever. A connecting rope is connected to one end of the locking lever, and the free end of the connecting rope movably passes through the fixing block and connects to the receiving plate. The receiving plate is slidably connected to the L-shaped groove. The engagement between the locking lever and the groove effectively restricts the position of the inclined plate, ensuring that the device maintains its preset shape under non-impact conditions. The first spring resets the locking lever, and the connection between the connecting rope and the receiving plate enables convenient control of the locking lever's state. When the receiving plate is under force, the locking lever can be pulled by the connecting rope to compress the first spring, causing the locking lever to disengage from the groove and releasing the restriction on the inclined plate.

[0010] Option 4, a preferred embodiment of Option 3, features a rectangular groove on the upper surface of the base plate corresponding to the receiving plate. This rectangular groove connects to an L-shaped circular groove. The top of the receiving plate protrudes from the base plate surface through the rectangular groove. The linkage mechanism includes an L-shaped connecting plate, one end of which is hinged to the buffer plate, and the other end of which is fixedly connected to the corresponding receiving plate. When the buffer plate is subjected to external forces such as vehicle impact, the connecting plate can synchronously move the receiving plate, thereby triggering the switch assembly to unlock the inclined plate, ensuring that the device can quickly initiate avoidance measures when impacted.

[0011] Option 5, a preferred embodiment of the basic option, features a plurality of parallel guide rods slidably connected to the support plate. These guide rods are fixedly connected to the buffer plate, and each guide rod is fitted with a second spring for pre-compression. The two ends of the second spring abut against the support plate and the buffer plate, respectively. A limiting pin is provided at the end of the guide rod furthest from the buffer plate. The pre-compression design of the second spring gives the buffer plate initial buffering capacity. When the buffer plate is impacted, the second spring first absorbs some of the impact energy through compression deformation, initially reducing the impact force on the device.

[0012] Option 6, a preferred option of the basic option, features arrayed mounting holes on both sides of the top of the support plate, and threaded screws on both sides of the guide sign display frame. The screws and mounting holes are quickly locked together by nuts. This structure allows for the rapid replacement of different guide signs according to construction needs, and the threaded connection allows for adjustment of the guide sign height.

A buffer plate 5 with a limiting slide rail is provided at the bottom of the support plate 2 on one side of the guide sign display frame 4. A switch assembly for controlling the locking state of the inclined plate 3 is provided inside the base plate 1. The switch assembly is drivenly connected to the buffer plate 5 through a linkage mechanism. A longitudinally extending groove 6 is provided on the upper surface of the base plate 1. The bottom end of the inclined plate 3 is slidably connected to the groove 6. The bottom of the inclined plate 3 has symmetrical slots 7 on both sides. The inner wall of the slide 6 has L-shaped circular grooves 8 on both sides corresponding to the slots 7. The switch assembly is integrated into the L-shaped circular groove 8 and selectively engages with the slots 7. The switch assembly includes a lever 9 and a receiving plate 13. The lever 9 is slidably connected in the L-shaped circular groove 8. One end of the lever 9 is plugged into the slot 7. A fixing block 10 is fixedly connected in the L-shaped circular groove 8. A first spring 11 is provided between the fixing block 10 and the lever 9. One end of the lever 9 is connected to a connecting rope 12. The free end of the connecting rope 12 moves through the fixing block 10 and connects to the receiving plate 13. The receiving plate 13 is slidably connected to the L-shaped circular groove 8.

[0016] A rectangular groove 14 is provided on the upper surface of the base plate 1 at the position corresponding to the receiving plate 13. The rectangular groove 14 is connected to the L-shaped circular groove 8. The top of the receiving plate 13 is exposed on the surface of the base plate 1 through the rectangular groove 14. The linkage mechanism includes a connecting plate 15. One end of the connecting plate 15 is hinged to the buffer plate 5. When the buffer plate 5 tilts, the buffer plate 5 can rotate 90 degrees relative to the connecting plate 15. The end of the connecting plate 15 is fixedly connected to the corresponding receiving plate 13. A plurality of parallel guide rods 16 are slidably connected to the support plate 2. The guide rods 16 are connected to the buffer plate. 5. Fixed connection: Each guide rod 16 is fitted with a second spring 17 for pre-tightening. The two ends of the second spring 17 abut against the support plate 2 and the buffer plate 5 respectively. The end of the guide rod 16 away from the buffer plate 5 is provided with a pin for limiting. The top of the support plate 2 is provided with an array of assembly holes 18 on both sides. The guide plate display frame 4 is provided with threaded screws 19 on both sides. The screws 19 and the assembly holes 18 are quickly locked by nuts. The bottom of the receiving plate 13 is rotatably connected to a pulley, which is slidably connected to the L-shaped groove 8.

[0017] The implementation method of this embodiment is as follows: When the device is impacted by a vehicle, the vehicle first impacts the buffer plate 5. The impact force is transmitted to the guide rod 16 through the buffer plate 5. The guide rod 16 slides towards the support plate 2, and at the same time, the second spring 17 is compressed to achieve the first stage of buffering. As the impact continues, the buffer plate 5 pushes the connecting plate 15. The connecting plate 15 drives the receiving plate 13 to slide in a direction within the rectangular groove 14. During the movement of the receiving plate 13, the connecting rope 12 is pulled. The connecting rope 12 pulls the locking rod 9 in the L-shaped circular groove 8. When the traction force... When the preset elastic force of the first spring 11 is exceeded, the locking rod 9 disengages from the slot 7 of the inclined plate 3. At this time, the bottom end of the inclined plate 3 is released from constraint and slides rapidly along the slide 6 under the action of impact inertia. The hinge point between the support plate 2 and the base plate 1 loses the oblique support force. Under the action of gravity, the support plate 2 tilts in the direction of impact with the hinge axis as the center. The buffer plate 5 maintains synchronous movement with the support plate 2 through the guide rod 16. The guide plate display frame 4 tilts as a whole with the support plate 2 through the rigid connection between the screw 19 and the assembly hole 18.

[0018] The entire process utilizes a combination of secondary buffering and mechanical triggering to ensure that the device quickly enters an avoidance state after absorbing some of the impact energy. This reduces the risk of secondary damage to the vehicle and creates passage space for the vehicle through orderly tilting. The movement trajectories of each component are precisely constrained by limiting structures such as the slide groove 6 and guide rod 16 to prevent unexpected deflection or jamming.
