Description

Technical Field

[0001] This utility model relates to the field of road construction protection technology, and in particular to an isolation device for highway construction safety. Background Technology

[0002] Highways, or expressways for short, are roads specifically designed for high-speed automobile travel. The definition of highways varies across different countries, regions, eras, and research fields. According to China's "Highway Engineering Technical Standards," highways are multi-lane roads with separate lanes and directions for automobiles, and all access is controlled. Safety isolation during highway construction is equally important.

[0003] During highway construction, safety barriers are typically used to enclose the construction area in order to alert drivers to slow down and avoid the site, and to protect the safety of construction workers. Existing barriers, due to cost considerations, mostly use steel pipe fences, cement barriers, or plastic barriers. These devices are inconvenient to transport and have poor cushioning effects. If vehicle speed cannot be controlled in a timely and effective manner, vehicles can easily knock open the barriers or push them forward. Existing barriers lack protective cushioning measures, posing a certain threat to the safety of construction workers or equipment. Utility Model Content

Detailed Implementation

[0018] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Reference Figure 1-3 A safety isolation device for highway construction includes a base plate 1 and a water tank seat 2. The water tank seat 2 has a connecting ring 21 for connecting other isolation devices in series or fixing the isolation devices to the road surface to improve isolation reliability. The base plate 1 and the water tank seat 2 are slidably connected. A slider 11, T-shaped, is provided on the upper side of the base plate 1 and is detachably connected to the base plate 1. A groove 22, adapted to the slider 11, is provided on the lower side of the water tank seat 2, allowing the slider 11 to slide within the groove 22. Both the slider 11 and the groove 22 are equipped with multiple... The sliding grooves 22 are arranged in parallel to each other, which limits the sliding direction between the base plate 1 and the water tank seat 2 and improves the reliability of the sliding connection. One end of the sliding groove 22 is provided with a limiting block to prevent the base plate 1 and the water tank seat 2 from sliding off. The other end is open to facilitate the disassembly of the slider 11. A strong magnet 13 is provided on the side of the slider 11 near the limiting block. An installation groove adapted to the strong magnet 13 is opened on the slider 11. A buffer pad 12 is provided in the installation groove. After the base plate 1 and the water tank seat 2 slide relative to each other, they are fixed by the strong magnet 13 for positioning.

[0020] The base plate 1 is made of steel plate and is fabricated directly on the construction site. The slider 11 is installed by bolts. The larger the size of the base plate 1, the higher the reliability. The size of the base plate 1 is adjusted according to the actual site conditions.

[0021] A counterweight water tank 3 is provided on the upper side of the water tank base 2. The counterweight water tank 3 is detachably connected to the water tank base 2, which facilitates disassembly and replacement and reduces maintenance costs. The counterweight water tank 3 is triangular prism-shaped with the center of gravity located on the lower side. The end of the counterweight water tank 3 is provided with an inlet 31 and a outlet 32. The inlet 31 and the outlet 32 ​​are provided with sealing caps for water inlet and outlet, adjusting the overall weight of the equipment. After water is discharged, it is easy to move. After installation, water is added to increase the counterweight and improve the reliability of interception.

[0022] The counterweight water tank 3 is equipped with anti-collision bags 4 on both sides. The anti-collision bags 4 are set on the inclined side wall of the counterweight water tank 3. The anti-collision bag 4 is equipped with a valve on one side for inflation and deflation to adjust the air pressure inside the anti-collision bag 4. The top of the counterweight water tank 3 is equipped with a protective airbag assembly 5. The protective airbag assembly 5 includes a protective cover 51, an inflatable airbag 52 and a rapid inflation device 53. The inflatable airbag 52 is folded and stored in the protective cover 51. The inflatable airbag 52 is made of rubber. After inflation, it is elastic and absorbs the impact when it hits workers or equipment to protect pedestrian safety. At the same time, after inflation, it is located above the front of the vehicle to limit the upward movement of the front of the vehicle 6 and reduce the risk of loss of vehicle control.

[0023] The anti-collision bag 4 is equipped with an activation device 41 on one side. The activation device 41 includes a pressure sensor and a vibration sensor. The activation device 41 is electrically connected to the rapid inflation device 53. The rapid inflation device 53 includes a gas cylinder and an electric control valve. The gas cylinder is a high-pressure gas cylinder filled with carbon dioxide gas. The gas cylinder is connected to the expansion airbag 52 through the electric control valve. The activation device 41 controls the opening and closing of the electric control valve to open the gas cylinder and realize rapid inflation.

[0024] The excitation device 41 can also be a gas generator, which can quickly generate gas through a chemical reaction, shorten the inflation time, and protect personnel safety;

[0025] In this embodiment, isolation devices are set up in the construction or closed sections of the highway. Multiple isolation devices are set up according to the construction location and connected to each other by steel cables. Both ends are connected to road bollards or guardrails to form a whole, thereby improving the reliability of the anti-collision isolation.

[0026] like Figure 3 As shown, when vehicle 6 hits the isolation device, the front of the vehicle contacts the anti-collision bag 4, the anti-collision bag 4 deforms under force to relieve the impact. At the same time, the pressure sensor and vibration sensor detect the collision accident, the excitation device 41 controls the electronic control valve to open, the gas cylinder fills the inflatable airbag 52 with gas, the inflatable airbag 52 expands the protective cover 51 and inflates.

[0027] At the same time, the counterweight water tank 3 slides under the force, the water tank seat 2 slides on the base plate 1, and the strong magnet 13 attracts and fixes the water tank seat 2 and the base plate 1 in relative position. The base plate 1 is inserted into the underside of the vehicle 6, and the vehicle 6 and the isolation device slide together to avoid direct collision or knocking down, ensuring that the isolation device is in front of the vehicle 6 to ensure the isolation and anti-collision effect. An anti-slip layer is set on the underside of the base plate 1 to increase the friction between the base plate 1 and the road surface and improve the braking force of the vehicle 6 after the impact.

[0028] The inflatable airbag 52 and the crash cushion 4 are located in front of the vehicle 6 to protect the equipment or personnel that are hit, thereby improving construction safety.
