Description

Technical Field

[0001] This utility model relates to the field of highway equipment, and in particular to a hydraulic interception device for highways. Background Technology

[0002] In existing highway management and traffic control systems, traditional barrier gates are widely used for scenarios such as traffic restrictions, vehicle stops, and security checks. These devices are typically rigid structures that are driven to rise and fall via hydraulic or electric means to control vehicle traffic. However, in actual use, traditional barrier gates pose numerous safety hazards.

[0003] First, when the barrier encounters an emergency during its raising, lowering, or blocking operation (such as a vehicle forcibly breaking through the barrier), the existing barrier structure is too rigid and lacks an effective buffering mechanism, making it highly susceptible to direct impact with the vehicle, potentially leading to personal injury or property damage. Second, if the barrier collides with a large vehicle (especially a truck), the impact force is concentrated at the front or top of the vehicle, easily causing damage to the vehicle or the barrier, resulting in traffic safety issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the lack of a buffer mechanism in the interception bar, which makes it easy for the bar to collide directly with the vehicle when it tries to break through the barrier, resulting in damage to both the vehicle and the interception bar and reduced safety. This invention provides a hydraulic interception device for highways.

[0005] In a first aspect, the present invention provides a hydraulic interception device for highways, including a bracket, the bracket including a mounting plate, a plurality of outriggers provided below the mounting plate, a driving device provided on the top of the mounting plate, the driving device being connected to an interception structure, the interception structure being capable of lifting and lowering along the outriggers;

[0006] The interception structure includes a hydraulic damping device, which is used to reduce the vertical impact force on the interception structure.

[0007] An elastic structure is provided between the support leg and the interception structure, the elastic structure being used to reduce the horizontal impact force on the interception structure.

[0008] This utility model provides a hydraulic interception device for highways. By incorporating a drive unit, the entire interception structure is raised and lowered to intercept and release vehicles. A hydraulic damping device is installed within the interception structure. When a vehicle forcibly attempts to pass through the barrier during the lowering process, the hydraulic damping absorbs the vertical impact force received upon contact with the vehicle's top, reducing the risk of damage to the interception structure or the intercepted vehicle due to concentrated impact force. This reduces the risk of personal injury and property damage. Furthermore, an elastic structure buffers the connection between the interception structure and its outriggers. In the event of a horizontal collision, the elastic structure deforms within a certain range to absorb energy, mitigating the transmission of instantaneous horizontal impact force and further reducing the risk of damage to the interception structure and the vehicle's sides. Through the synergistic effect of the hydraulic damping device and the elastic structure, this hydraulic interception device exhibits excellent cushioning and shock absorption performance and structural stability when facing accidental vehicle incursions or abnormal impacts. This not only enhances the device's impact resistance but also significantly improves its safety and reliability in practical road interception applications.

[0009] Preferably, the interception structure includes a connecting plate located below the mounting plate. The bottom surface of the connecting plate is provided with an interception part, and the side of the interception part away from the connecting plate is provided with a buffer member, the buffer member having an arc-shaped cross-section.

[0010] By incorporating a buffer, when a vehicle attempting to break through the checkpoint comes into contact with the interceptor structure, the buffer can absorb some of the impact force.

[0011] Preferably, the top of the connecting plate is connected to the bottom of the mounting plate by a chain.

[0012] By connecting the connecting plate and the mounting plate with chains, even if the entire interception structure breaks, the traction of the chains can reduce the amount of debris falling to the ground and affecting vehicles.

[0013] Preferably, the hydraulic damping device is located inside the interception section. The hydraulic damping device includes a pressure sensor, a proportional hydraulic valve, and an accumulator. The pressure sensor is used to collect the vertical impact force received by the interception section. The proportional hydraulic valve is electrically connected to the pressure sensor and is used to adjust the flow rate and pressure of hydraulic oil according to the vertical impact force received by the interception section collected by the pressure sensor. The accumulator is hydraulically connected to the proportional hydraulic valve and is used to store and release hydraulic energy.

[0014] Preferably, the drive unit body is a servo motor.

[0015] Preferably, the side of the support leg facing the connecting plate is provided with a snap-fit ​​part, the side of the snap-fit ​​part facing the connecting plate is provided with a snap-fit ​​groove, the connecting plate is provided with a snap-fit ​​block, and the snap-fit ​​block is configured to connect with the snap-fit ​​groove when the interception structure moves horizontally.

[0016] By setting up a slot and a block, and by connecting the slot and the block when the interception structure moves horizontally (when the truck head contacts the interception structure), the displacement of the interception structure can be reduced.

[0017] Preferably, the side of the snap-fit ​​portion away from the slot is connected to the elastic structure, and one end of the elastic structure is connected to the support leg and the other end is connected to the snap-fit ​​portion.

[0018] The support leg and the locking part are connected by an elastic structure, so that the locking block can be buffered after contacting the locking slot, reducing damage to the interception structure.

[0019] Preferably, the elastic structure is a disc spring assembly.

[0020] By setting the elastic structure as a disc spring assembly, good elastic cushioning performance is provided when the interceptor is subjected to horizontal impact (during horizontal movement).

[0021] Preferably, the bracket is provided with a control device, which is electrically connected to the drive device.

[0022] Preferably, the bracket includes a mounting frame for protecting the drive unit, and a camera is provided on the top of the mounting frame for recognizing license plates.

[0023] Preferably, the bracket further includes a limiting block, which is disposed on the movement trajectory of the interception structure and is used to limit the movement range of the interception structure.

[0024] By setting limit blocks on the support and arranging them on the movement trajectory of the intercepting structure, the lifting stroke of the intercepting structure can be effectively limited, preventing it from operating beyond the set range and reducing structural damage or safety accidents caused by misoperation or malfunction.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This utility model provides a hydraulic interception device for highways. By incorporating a drive unit, the entire interception structure is raised and lowered to intercept and release vehicles. A hydraulic damping device is installed within the interception structure. When a vehicle forcibly breaks through the barrier during the lowering process, the hydraulic damping device absorbs the vertical impact force received upon contact with the vehicle's top, reducing the risk of damage to the interception structure or the intercepted vehicle due to concentrated impact force, thus lowering the risk of personal injury and property damage. Furthermore, an elastic structure buffers the connection between the interception structure and the outriggers. When a horizontal collision occurs, the elastic structure deforms within a certain range to absorb energy, mitigating the transmission of instantaneous horizontal impact force and further reducing the risk of damage to the interception structure and the vehicle's sides. Through the synergistic effect of the hydraulic damping device and the elastic structure, this hydraulic interception device exhibits excellent buffering and shock absorption performance and structural stability when facing accidental vehicle incursions or abnormal impacts. This not only improves the device's impact resistance but also significantly enhances its safety and reliability in practical road interception applications. Attached Figure Description

[0042] Example 1

[0043] like Figure 1 , Figure 4 , Figure 5 and Figure 6 A hydraulic interceptor for highways is shown, comprising a support 1 for mounting the interceptor, a drive device 2 above the support 1, and an interceptor structure 3 connected to the drive device 2. The drive device 2 enables the interceptor structure 3 to move up and down along the height of the support 1. The interceptor includes a connecting plate 32 connected to the support 1, and an interception section 33 below the connecting plate 32. A hydraulic damping device 31 is provided within the interception section 33. The hydraulic damping device 31 includes a pressure sensor, a proportional hydraulic valve, and an accumulator. The pressure sensor is used to collect the vertical impact force received by the interception section 33. The proportional hydraulic valve is electrically connected to the pressure sensor and is used to adjust the pressure based on the force collected by the pressure sensor. The vertical impact force received by the intercepting part 33 is used to adjust the flow and pressure of the hydraulic oil. The accumulator is hydraulically connected to the proportional hydraulic valve to store and release hydraulic energy. When the intercepting structure 3 is lowered, the bottom of the intercepting structure 3 contacts the top of the vehicle that broke through the checkpoint. At this time, the intercepting part 33 is subjected to a vertical force. The force received by the intercepting part 33 is collected by the pressure sensor and fed back to the proportional hydraulic valve. After receiving the force collected by the pressure sensor, the proportional hydraulic valve starts to adjust the flow and pressure of the hydraulic oil. At this time, the accumulator stores and releases the adjusted hydraulic oil, thereby offsetting part of the vertical impact force received by the intercepting part 33 and reducing the possibility of damage to the entire intercepting part 33 due to excessive impact force.

[0044] Specifically, when the vehicle collides with the interceptor 33, the interceptor 33 is lifted upward by the vertical impact force. At this time, the pressure sensor receives the vertical impact force received by the interceptor 33 and converts it into an electrical signal, which is transmitted to the proportional hydraulic valve. The proportional hydraulic valve adjusts the flow rate and pressure of the hydraulic oil according to the magnitude of the impact force (when the impact force is large, the proportional hydraulic valve increases the valve opening to accelerate the flow of hydraulic oil to relieve pressure; when the impact force is small, the proportional hydraulic valve decreases the valve opening to limit the flow rate of hydraulic oil). The hydraulic oil after energy absorption and release adjustment enters the accumulator, where the impact energy is converted into hydraulic potential energy. When the impact force weakens, the accumulator releases the stored hydraulic oil, pushing the oil to flow back into the system.

[0045] Furthermore, the support 1 includes a leg 12, on which a latching part 121 is embedded. The side of the latching part 121 facing the leg 12 has an elastic structure 4, and the side of the latching part 121 away from the elastic structure 4 has a slot 1211. The slot 1211 is arranged along the height direction of the leg 12. A locking block 321 is provided on the connecting plate 32, which can connect with the slot 1211. Specifically, when the truck tries to break through the barrier, the truck's front end contacts the intercepting structure 3. During the truck's movement... Under the impact, the interception structure 3 is displaced, causing the locking block 321 on the connecting plate 32 to engage with the slot 1211. Under the action of inertia, the locking block 321 impacts the slot 1211. At this time, the elastic structure 4 on the locking part 121 can buffer the impact force of the locking block 321 on the slot 1211, reducing the probability of damage to the entire interception structure 3. The above situation is that the driver braked suddenly during the truck's attempt to break through the checkpoint, causing the front of the truck to come into contact with the interception structure 3, and it did not directly break through the checkpoint.

[0046] In this invention, the slots 1211 of the latching part 121 can be arranged at intervals, or the slots 1211 can be a continuous structure (only one is provided), such as... Figure 7 and Figure 8 As shown.

[0047] In one or more embodiments, the bracket 1 includes a mounting plate 11, with a driving device 2, which is a servo motor, disposed on the top of the mounting plate 11. The driving device 2 is connected to a connecting plate 32 via a hinge. When the servo motor rotates, it retracts the hinge, thereby driving the connecting plate 32 to rise. When the servo motor rotates, it lowers the hinge, causing the connecting plate 32 to descend. Figure 1 , Figure 2 and Figure 3 As shown.

[0048] In one or more embodiments, the end of the intercepting part 33 away from the connecting plate 32 is provided with a buffer 34, which is a rubber part with an arc-shaped cross-section, such as... Figure 2 and Figure 3 As shown.

[0049] In one or more embodiments, the top of the connecting plate 32 is connected to the bottom of the mounting plate 11 by a chain 5. By connecting the connecting plate 32 and the mounting plate 11 by the chain 5, if the entire interception structure 3 breaks, the traction of the chain 5 can reduce the amount of debris falling to the ground and affecting driving vehicles.

[0050] In one or more embodiments, the bracket 1 is provided with a control device 6, and the control device 6 is electrically connected to the drive device 2, such as... Figure 3 As shown.

[0051] In one or more embodiments, the bracket 1 includes a mounting frame 13 for protecting the drive device 2. A camera 7 is located at the top of the mounting frame 13 for recognizing license plates, such as... Figure 3 As shown.

[0052] In one or more embodiments, the support 1 further includes a limiting block 14, which is disposed on the movement trajectory of the intercepting structure 3. The limiting block 14 is used to limit the movement range of the intercepting structure 3. By setting the limiting block 14 on the support 1 and arranging it on the movement trajectory of the intercepting structure 3, the lifting stroke of the intercepting structure 3 can be effectively limited, preventing it from operating beyond the set range and reducing structural damage or safety accidents caused by misoperation or malfunction. Figure 3 As shown.

[0053] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
