Description

Technical Field

[0001] This invention relates to the field of traffic safety technology, and in particular to a height restriction device for traffic safety. Background Technology

[0002] Height restriction devices play a crucial role in modern road traffic management, primarily preventing collisions between oversized vehicles and fixed structures such as bridges and tunnels, thus ensuring road safety and smooth traffic flow. Existing height restriction devices mostly employ fixed structures, achieving their purpose by installing height restriction poles or frames at a fixed height above the road. With technological advancements, intelligent and automated height restriction devices are gaining increasing attention. These devices can adjust their height according to different needs and monitor and provide real-time feedback on vehicle height through various methods, improving the intelligence and effectiveness of height restriction devices, thereby enhancing the safety and efficiency of road traffic management.

[0003] However, existing technologies have significant limitations: fixed height restriction devices cannot be adjusted, easily leading to direct collisions between vehicles and the devices, causing damage to both vehicles and facilities. Furthermore, these devices rely solely on visual cues or warning signs to alert drivers when vehicles exceed the height limit, lacking a physical feedback mechanism. Drivers may easily overlook or fail to perceive the vehicle's excessive height, increasing safety hazards. Height restriction devices are constantly exposed to the natural environment, especially at the connection between the height restriction bar and the supporting column, making them susceptible to corrosion. This can cause the height restriction bar to fall, potentially striking vehicles and causing serious accidents. Therefore, there is an urgent need for a height restriction device that can prevent corrosion and fall, and provides physical feedback and warnings to better ensure traffic safety. Summary of the Invention

[0010] As a preferred embodiment of the transportation safety height restriction device of the present invention, the roller is further provided with a fall arresting ring and an impact plate. The fall arresting ring is located on the inner side of the roller near both ends, and the impact plate is located on the end face of the roller.

[0011] In a preferred embodiment of the height restriction device for transportation safety described in this invention, the impact plates are distributed in a ring array; the outer surface of the roller is also provided with rubber strips, which are distributed in a ring array.

[0012] In a preferred embodiment of the transportation safety height restriction device of the present invention, the striking component and the fall arrestor ring are always in contact.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a traffic safety height restriction device, which includes a roadbed 100, a deceleration component 200 and a striking component 300.

[0028] Specifically, the roadbed 100 includes posts 101 and warning signs 102. Posts 101 are installed at both ends of the top of the roadbed 100, and warning signs 102 are installed between the posts 101. Both ends of the warning signs 102 are connected to the posts 101. The warning signs 102 use eye-catching fonts to visually remind drivers to pay attention to the height restriction device.

[0029] The deceleration assembly 200 includes a rotating component 201 and a connecting component 202. The connecting component 202 is disposed on the column 101, and the rotating component 201 and the connecting component 202 are rotatably engaged.

[0030] The striking component 300 is positioned between the sign 102 and the connector 202.

[0031] When in use, when an oversized vehicle enters the roadbed at 100, the vehicle comes into contact with the rotating component 201, causing the rotating component 201 to rotate and rise. The rotating component 201 then repeatedly contacts the striking component 300, emitting a striking sound, which audibly alerts the driver that the vehicle is oversized. After the rotating component 201 comes into contact with the vehicle, the rotating component squeezes the vehicle, causing the vehicle to decelerate, allowing the driver to perceive the oversized situation through power loss, thereby obtaining physical feedback.

[0032] Example 2

[0033] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the connector 202 includes a connecting base 202a, a shaft seat 202b, and a spring seat 202c. The connecting base 202a is located inside the column 101, the shaft seat 202b is located on one side of the connecting base 202a, and the spring seat 202c is located at the end of the shaft seat 202b.

[0035] Specifically, the rotating component 201 includes a rotating bushing 201a, a first return spring 201b, and a sliding sleeve 201c. The rotating bushing 201a is rotatably engaged with the bearing seat 202b. The first return spring 201b is disposed between the rotating bushing 201a and the spring seat 202c. The sliding sleeve 201c is disposed on the top of the rotating bushing 201a. A contact component 203 is also connected inside the sliding sleeve 201c.

[0036] Specifically, the contact element 203 includes a roller 203a, a pad 203b, a sliding rod 203c, and a compression spring 203d. The pad 203b is located on the upper side of the inner wall of the roller 203a, near both ends. The sliding rod 203c is located at the bottom of the pad 203b and slides with the sliding sleeve 201c. The compression spring 203d is located on the outside of the sliding sleeve 201c and is located between the end face of the pad 203b and the rotating bushing 201a.

[0037] It is worth noting that in the initial state, the first return spring 201b is at its original length, and under the action of the first return spring 201b, the sliding rod 203c and the sliding sleeve 201c are located above the rotating bushing 201a in the initial state. At this time, the compression spring 203d is at its original length, and under the action of the compression spring 203d, the sliding rod 203c is partially located outside the sliding sleeve 201c. At this time, the axis of the rotating bushing 201a is located below the axis of the roller 203a.

[0038] When a vehicle exceeding the distance between the deceleration assembly 200 and the roadbed 100 passes by, the overheight portion of the vehicle will first contact the outer surface of the deceleration assembly 200. Since the sliding rod 203c and the sliding sleeve 201c can adjust the distance between the pad 203b and the rotating bushing 201a through telescopic movement, it is ensured that when an overheight vehicle passes by the device, the deceleration assembly 200 will not directly collide with the overheight portion of the vehicle. Instead, the contact element 203 moves upward as a whole under the push of the vehicle, avoiding the problem of traditional height restriction devices being unable to move and causing damage to the vehicle when in contact with it. This improves the device's ability to protect the vehicle and reduces damage to overheight vehicles.

[0039] Specifically, the roller 203a is also provided with a fall arresting ring 203e and an impact plate 203f. The fall arresting ring 203e is located on the inner side of the roller 203a near both ends, and the impact plate 203f is located on the end face of the roller 203a.

[0040] Specifically, the impact plates 203f are distributed in a ring array; the outer surface of the roller 203a is also provided with rubber strips 203g, which are distributed in a ring array.

[0041] When the overheight vehicle comes into contact with the contact element 203, the friction generated when the vehicle contacts the rubber strip 203g will also cause the contact element 203 to rotate as a whole. When the contact element 203 rotates to 90 degrees, the sliding rod 203c and the sliding sleeve 201c rotate to the bottom of the rotating bushing 201a. The pushing action of the vehicle and the elastic force of the compression spring 203d, due to the small distance between the rotating bushing 201a and the lower inner wall of the roller 203a, cause the weight of the contact element 203 and the elastic force of the compression spring 203d to be transmitted to the vehicle through the contact surface between the contact element 203 and the overheight part of the vehicle, resulting in an increased vehicle load and a significant loss of power. The driver in the cab can determine whether the vehicle is in contact with the contact element 203 by the loss of power, thus knowing whether the vehicle is overheight, which serves as a physical warning.

[0042] Specifically, the striking component 300 and the fall arrestor ring 203e remain in contact at all times.

[0043] Specifically, the striking assembly 300 includes a sliding sleeve 301, a mating slide block 302, a torsion bar 303, a mounting plate 304, and a striking plate 305. The sliding sleeve 301 is slidably engaged with the column 101. The mating slide block 302 is located at the lower end of the sliding sleeve 301, and the upper end of the mating slide block 302 is in contact with the inner wall of the roller 203a. The middle part of the torsion bar 303 is rotatably engaged with one side of the outer surface of the sliding sleeve 301 near the top. The mounting plate 304 is located on one side of the sliding sleeve 301 in front of the torsion bar 303, and the striking plate 305 is mounted on the mounting plate 304.

[0044] Specifically, a slot 302a is provided on the side of the slide 302, which cooperates with the anti-fall ring 203e;

[0045] The slot 302a engages with the anti-fall ring 203e, which can slide within the slot 302a, allowing the entire striking assembly 300 to move synchronously with the rise and fall of the roller 203a. This ensures that the bottom of the torsion bar 303 is always in contact with the impact plate 203f, while the top of the torsion bar 303 can also stably impact the impact plate 305, thus ensuring the stability of the device during operation.

[0046] Specifically, the torsion bar 303 is also provided with a second return spring 303a and a hammer 303b. The second return spring 303a is located between the end face of the torsion bar 303 and the sliding sleeve 301, and the hammer 303b is located above the torsion bar 303. The bottom of the torsion bar 303 is in contact with the impact plate 203f.

[0047] In its initial state, the second return spring 303a is at its original length, at which point the upper end of the torsion bar 303 is disengaged from the striking plate 203f. As the contact member 203 rotates as a whole, the striking plate 203f continuously contacts and disengages from the bottom of the torsion bar 303, causing the torsion bar 303 to rotate at a small angle. After disengaging from the striking plate 203f, it resets under the elastic force of the second return spring 303a. During the reset process, the hammer at the top of the torsion bar 303 strikes one side of the striking plate 305 and produces a warning sound, serving as an auditory prompt.

[0048] Furthermore, when the connection between the base 202a and the bearing 202b is corroded and broken, the deceleration assembly 200 falls off. Since one end of the sliding block 302 is provided with a slot 302a, and this slot 302a cooperates with the anti-fall ring 203e, the deceleration assembly 200 will cause the striking assembly 300 to slide down synchronously during its detachment. As the striking assembly 300 slides down the upright 101, it will contact the base 202a and act as a stop, preventing the deceleration assembly 200 from falling directly and colliding with the vehicle, thus avoiding a traffic accident and improving the safety of the device.

[0049] In use, when a vehicle exceeding the distance between the deceleration assembly 200 and the roadbed 100 passes by, the overheight portion of the vehicle will first contact the outer surface of the deceleration assembly 200. Since the sliding rod 203c and the sliding sleeve 201c can adjust the distance between the pad 203b and the rotating bushing 201a through telescopic movement, it ensures that when an overheight vehicle passes over the device, the contact element 203 will not directly impact the overheight portion of the vehicle. Instead, the contact element 203 moves upward as a whole under the vehicle's thrust. When the overheight vehicle contacts the contact element 203, the friction generated when the vehicle contacts the rubber strip 203g will also drive the contact element 203. 03. The entire assembly rotates. When contact 203 rotates to 90 degrees, sliding rod 203c and sliding sleeve 201c rotate to below rotating bushing 201a. The pushing action of the vehicle and the elastic force of compression spring 203d, combined with the small distance between rotating bushing 201a and the lower inner wall of roller 203a, cause the weight of contact 203 and the elastic force of compression spring 203d to be transmitted to the vehicle through the contact surface between contact 203 and the vehicle's overhanging section. This increases the vehicle's load and causes significant power loss. The driver in the cab can use this power loss to determine whether the vehicle is in contact with the vehicle. When contactor 203 makes contact, it detects whether the vehicle is overheight. As contactor 203 rotates, impact plate 203f continuously contacts and disengages from the bottom of torsion bar 303, causing torsion bar 303 to rotate at a small angle. After disengaging from impact plate 203f, it resets under the force of second return spring 303a. During the reset process, hammer at the top of torsion bar 303 strikes one side of impact plate 305 and produces a warning sound, serving as an auditory alert. Anti-fall ring 203e can slide within slot 302a, allowing the entire impact assembly 300 to move synchronously with the height rise and fall of roller 203a, ensuring the stability of torsion bar 303. The bottom can always maintain contact with the impact plate 203f, and the top of the torsion bar 303 can also stably impact the striking plate 305. When the connection between the connecting base 202a and the shaft seat 202b is corroded and broken, the deceleration assembly 200 falls off as a whole. Since one end of the sliding block 302 is provided with a slot 302a, and the slot 302a cooperates with the anti-fall ring 203e, the deceleration assembly 200 will drive the striking assembly 300 to slide down synchronously during the process of falling off. As the striking assembly 300 slides down along the upright 101, it will contact the connecting base 202a and play a role in stopping the movement.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
