Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, specifically to a safety protection side beam anti-collision device for road and bridge construction. Background Technology

[0002] During the construction and operation of roads and bridges, the side beams, as an important component of the road and bridge structure, must withstand potential risks such as vehicle impacts and external collisions. Their protective safety is directly related to the stability of the road and bridge structure and traffic safety.

[0003] Currently, the edge beam protection devices commonly used in road and bridge construction are mostly traditional rigid structures with limited anti-collision and buffering performance. These devices lack an effective force-dissipating mechanism, and when hit by a vehicle, they can easily transmit the impact force directly to the edge beam body, causing the edge beam to crack, deform, or even fall off, seriously affecting the structural safety of the road and bridge. Furthermore, a single protective structure is difficult to cope with impacts of different forces. Minor collisions may damage the device, while severe impacts cannot effectively buffer it, resulting in poor protection. Therefore, a safety protection edge beam anti-collision device for road and bridge construction is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection side beam anti-collision device for road and bridge construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection side beam anti-collision device for road and bridge construction, comprising a device body, an installation groove provided in the device body, two fixing pipes installed in the installation groove, a fixing rod installed at one end of the fixing pipe, two sliding sleeves installed on the side of the fixing rod, a connecting rod installed at one end of the sliding sleeve, a fixing sleeve installed at one end of the connecting rod, a spring sleeved on the side of the fixing rod, and an anti-collision plate installed at one end of the fixing sleeve.

[0006] Preferably, both the sliding sleeve and the fixed sleeve are equipped with multiple rotating shafts, and the connecting rod is mounted on the sliding sleeve and the fixed sleeve via the rotating shafts.

[0007] Preferably, a sliding rod is installed at one end of the fixed tube, and a circular plate is installed on the side of the sliding rod.

[0008] Preferably, the fixed tube has an inner cavity, a connecting column is installed at one end of the slide rod, a piston plate is installed at one end of the connecting column, and a flow channel perforation is opened at one end of the piston plate.

[0009] Preferably, two mounting tubes are installed at the bottom of the main body of the device, and multiple threaded grooves are opened on the side of the mounting tubes, with multiple fixing bolts installed at one end of each threaded groove.

[0010] Preferably, one end of the crash barrier is equipped with multiple reflective stickers for reflective warning.

[0011] Preferably, the two ends of the spring are connected to two sliding sleeves, which are slidably mounted on the side of the fixed rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting a fixed tube and a fixed rod, the main body of the device is installed in a suitable position. When one end of the anti-collision plate is hit, the connecting rod connected to the fixed sleeve is squeezed and slides to both ends, causing the two sliding sleeves to slide on the fixed rod, thereby causing the spring to be stretched to offset the impact force on the anti-collision plate. The spring rebound causes the two sliding sleeves to reset and slide. The connecting rod joint rotates, thereby causing the anti-collision plate to reset, playing a buffering and anti-collision role, thereby reducing the probability of damage to the side beam.

[0013] (2) By setting up an inner cavity and piston plate, when the sliding sleeve slides on the fixed rod, if the impact force is large, the sliding sleeve will slide to abut against one end of the circular plate. When it continues to slide, it will drive the sliding rod to move in the inner cavity. The piston plate will slide in the inner cavity through the connecting column, which will squeeze the hydraulic oil in the inner cavity. The hydraulic oil will flow through the flow channel perforation. Since the flow channel perforation is small, it will generate resistance during flow, which will play a buffering role, further improving the overall unloading effect of the device and improving the applicability of the main body of the device.

[0016] 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.

[0017] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a safety protection side beam anti-collision device for road and bridge construction, including a device body 1. The device body 1 has an installation groove 2, and two fixing pipes 3 are installed in the installation groove 2. A fixing rod 4 is installed at one end of each fixing pipe 3. Two sliding sleeves 5 are installed on the side of each fixing rod 4. A connecting rod 6 is installed at one end of each sliding sleeve 5. A fixing sleeve 7 is installed at one end of each connecting rod 6. A spring 8 is sleeved on the side of each fixing sleeve 4. An anti-collision plate 9 is installed at one end of each fixing sleeve 7. Multiple rotating shafts 10 are installed in both the sliding sleeves 5 and the fixing sleeve 7. The connecting rod 6 is mounted on the sliding sleeves 5 and the fixing sleeve 7 via the rotating shafts 10. Two installation pipes 17 are installed at the bottom of the device body 1. Multiple threaded grooves 18 are opened on the side of each installation pipe 17. Multiple fixing bolts 19 are installed at one end of each threaded groove 18. Multiple reflective stickers 20 for reflective warning are installed at one end of the anti-collision plate 9. The two ends of the spring 8 are connected to two sliding sleeves 5. The sliding sleeves 5 are slidably installed on the side of the fixed rod 4. The main body 1 of the device is placed in the area to be installed and installed through the two mounting tubes 17 at the bottom. The fixing bolts 19 are passed through the threaded grooves 18 and fixed between the bolts and the preset column, so that the main body 1 of the device is placed in the protected area. The anti-collision plate 9 on the side of the main body 1 protects the side beam. When one end of the anti-collision plate 9 is impacted, the rotating shaft 10 at the connection of the connecting rod 6 is rotated through the connection of the fixed sleeve 7. After the connecting rod 6 is squeezed, the angle between it and the main body 1 of the device decreases, causing the two sliding sleeves 5 to slide on the fixed rod 4, thereby causing the spring 8 to be stretched to offset the impact force on the anti-collision plate 9. The spring 8 rebounds and causes the two sliding sleeves 5 to return to their original position, causing the angle between the two connecting rods 6 to increase and return to its original position, thereby causing the anti-collision plate 9 to return to its original position, thus playing a role in buffering and preventing collisions.

[0018] Example 2: Figure 4 and 5As shown, a slide rod 11 is installed at one end of the fixed tube 3, and a circular plate 12 is installed on the side of the slide rod 11. An inner cavity 13 is opened inside the fixed tube 3. A connecting column 14 is installed at one end of the slide rod 11, and a piston plate 15 is installed at one end of the connecting column 14. A flow channel perforation 16 is opened at one end of the piston plate 15. If the impact force is large, the slide sleeve 5 will slide to abut against one end of the circular plate 12. After the circular plate 12 is squeezed, it will drive the slide rod 11 to move in the inner cavity 13. The piston plate 15 is driven to slide in the inner cavity 13 through the connecting column 14, which squeezes the hydraulic oil in the inner cavity 13. The hydraulic oil flows through the flow channel perforation 16. Since the diameter of the flow channel perforation 16 is small, it will generate resistance during flow, which plays a buffering role and further improves the overall force relief effect of the device. The other features are the same as in Embodiment 1.

[0019] The working principle is as follows: The main body 1 of the device is placed in the area to be installed, and installed through the two mounting tubes 17 at the bottom. The fixing bolts 19 are passed through the threaded grooves 18 and fixed between the bolts and the preset column, so that the main body 1 of the device is placed in the protected area. The anti-collision plate 9 on the side of the main body 1 protects the side beam. When one end of the anti-collision plate 9 is impacted, the rotating shaft 10 at the connection of the connecting rod 6 is rotated through the connection of the fixing sleeve 7. After the connecting rod 6 is squeezed, the angle between it and the main body 1 of the device decreases, causing the two sliding sleeves 5 to slide on the fixing rod 4, thereby causing the spring 8 to be stretched to offset the impact force on the anti-collision plate 9. The rebound of the spring 8 causes the two sliding sleeves 5 to return to their original position and slide, thereby driving the two connecting rods to slide back to their original position. The angle of the 6-axis increases and resets, thereby driving the anti-collision plate 9 to reset, which plays a role in buffering and preventing collisions. If the impact force is large, the sliding sleeve 5 will slide to abut against one end of the circular plate 12. After the circular plate 12 is squeezed, it will drive the sliding rod 11 to move in the inner cavity 13. Through the connecting column 14, it drives the piston plate 15 to slide in the inner cavity 13, squeezing the hydraulic oil in the inner cavity 13. The hydraulic oil flows through the flow channel perforation 16. Since the diameter of the flow channel perforation 16 is small, it will generate resistance during flow, which plays a buffering role, further improving the overall force relief effect of the device and improving the applicability of the main body 1 of the device. At night, the reflective sticker 20 on the anti-collision plate 9 plays a reflective warning role, reminding oncoming vehicles.
