Description

Technical Field

[0001] This invention relates to the field of collision safety for large-tonnage tank trucks in industrial production, and more specifically, to an energy dissipation and collision avoidance facility system. Background Technology

[0002] Typically, the track foundation is buried underground, and the rear area of ​​the foundation top slab usually contains hoisting holes or important equipment or structures. For large-tonnage tank cars running on the foundation top slab, in the event of an accident or other unforeseen circumstances, a crash barrier structure needs to be installed at the end of the track to stop the sliding tank car within a safe area, ensuring the smooth operation of the tank car and the safety of the structures behind the track.

[0003] Currently, when setting up the stopping structures at the ends of each track, a separate cantilevered stopping structure is typically installed on the top slab of the track foundation. This usually employs a cantilevered H-shaped or trapezoidal steel structure, with a buffer placed on the side of the tanker truck approaching to stop it. However, this type of independent cantilevered stopping structure on the top slab of the track foundation has significant limitations under the impact of large-tonnage tanker trucks: Firstly, due to the large weight of the tanker truck itself, the instantaneous impact force in an accident is also very large. This type of cantilevered stopping structure is difficult to effectively withstand the impact, requiring a sufficiently large cross-sectional dimension to effectively block the impact. This necessitates providing a large installation space behind the track, but the usable space behind the track is often limited, making it difficult to meet the installation space requirements. Secondly, the area behind the track foundation usually contains hoisting holes or other openings required for maintenance or production. For other important equipment or structures, if the cantilevered stop is damaged in an impact, the tanker truck may continue to slide, potentially overturning or impacting the structures or equipment behind it. This could cause serious safety accidents and property damage, severely impacting normal production operations. Thirdly, the cantilevered independent stop structure is fixed to the top surface of the track foundation. When the tanker truck impacts the stop, the base of the stop directly transfers the enormous impact force to the top slab of the foundation, causing severe damage. Since concrete top slabs are difficult to repair, this results in irreversible damage to the track foundation top slab. Therefore, this conventional cantilevered independent stop structure is unsuitable for stopping large-tonnage tanker trucks and cannot provide reliable safety, especially given the risk of irreversible damage to the foundation structure. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an energy dissipation and anti-collision facility system to solve the safety hazards of tanker operation under accident conditions caused by conventional cantilevered independent vehicle stops and the safety problem of the load-bearing capacity of the track foundation structure after impact.

[0005] The technical solution adopted by the present invention to solve its technical problem is: to construct an energy dissipation and anti-collision facility system, including a track foundation, a tank car, an energy dissipation wheel stop, an anti-collision beam, an energy dissipation wheel stop, and column piers;

[0006] The track foundation has a track groove on its top surface, and a rail is installed in the track groove. An energy-dissipating wheel stop is installed near the end section of the rail. The anti-collision beam is placed horizontally above the top surface of the track foundation and is perpendicular to the rail. The anti-collision beam is suspended and isolated from the top plate of the track foundation. An energy-dissipating vehicle stop is installed on the side of the anti-collision beam. The column piers are installed at both ends of the anti-collision beam and stand on the top surface of the side wall of the track foundation. A rear support leg is installed in the middle area of ​​the anti-collision beam. The rear support leg contacts the top surface of the track foundation but maintains relative sliding. A parking buffer is installed at the front end of the tank car.

[0007] According to the above scheme, hoisting holes, buildings, or production equipment are provided behind the track foundation.

[0008] According to the above scheme, the rails can be in single or multiple sets.

[0009] According to the above scheme, the energy dissipation wheel stop is clamped to the rail with bolts, and can still maintain damping sliding after clamping.

[0010] According to the above scheme, the anti-collision beam is a box-shaped steel beam or an H-shaped steel beam, and the bottom of the steel beam is equipped with rear support legs.

[0011] According to the above scheme, the rear support leg is located in the direction of the impact center line of the tanker truck, the bottom surface of the rear support leg is in contact with the top plate of the track foundation but can slide freely, and the rear support leg is a box-shaped or H-shaped steel.

[0012] According to the above scheme, the energy dissipation stop is located on the side of the anti-collision beam. The bottom of the front support leg of the energy dissipation stop is in contact with the top plate of the track foundation but can slide freely. The front support leg is a box-shaped or H-shaped steel, and the horizontal top rod is frustum-shaped, rectangular or circular.

[0013] According to the above scheme, the combined spring includes multiple individual springs, a limiting box, and an end plate. The individual springs are horizontally placed inside the limiting box, and the end plate is placed at the front end of the spring assembly. A certain gap is maintained between the end plate and the limiting box.

[0014] According to the above scheme, the column pier is erected on the side wall of the track foundation, and the column pier is provided with embedded parts on the inner side. The column pier is a reinforced concrete structure or a rectangular tube concrete structure.

[0015] According to the above scheme, the two ends of the anti-collision beam are connected to the column pier, and the connection method is welding or bolt connection.

[0016] The energy dissipation and collision avoidance system of the present invention has the following beneficial effects:

[0017] 1. Because the rails are equipped with energy-dissipating wheel stops, the wheel stops, when clamped, create a damping sliding effect, which dissipates energy and effectively reduces the impact speed of the tanker. The side of the crash beam has energy-dissipating car stops, and the front end of the car stops is equipped with a combined spring. The bottom of the crash beam and the energy-dissipating car stops is equipped with front and rear support legs. The bottom surfaces of the front and rear support legs are in contact with the top plate of the track foundation and can slide freely. The two ends of the crash beam are connected to the piers, and the piers are fixed to the side walls of the track foundation. Therefore, when a large-tonnage tanker collides with the rails, the speed is first appropriately reduced by the energy-dissipating wheel stops, and then the impact occurs with the energy-dissipating car stops. The combined springs at the front end of the energy-dissipating car stops further dissipate energy and prolong the impact duration, effectively reducing the impact effect. Then, the energy-dissipating car stops transfer the remaining impact effect to the crash beam. The crash beam deforms and dissipates energy after the impact, and then transfers the remaining impact force to the piers at both ends. Finally, the piers transfer the remaining impact effect to the side walls of the track foundation, thus resisting the huge impact effect in the event of a tanker accident.

[0018] 2. Because the front and rear support legs at the bottom of the crash beam and energy-dissipating stop only contact the top slab of the track foundation and can slide freely, they do not transmit impact force to the top slab structure. Furthermore, the front and rear support legs also prevent vertical deformation during impact, thus ensuring that the impact force is effectively transferred to the energy-dissipating structure. In this way, the purpose of energy-dissipating stopping can be achieved without damaging the top slab structure of the track. At the same time, the safety of structures behind the crash beam is ensured. Even if the columns at both ends of the crash beam are damaged during impact, timely reinforcement and repair are easy to carry out later without affecting normal production operations.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] refer to Figure 1 , Figure 2 This embodiment provides an energy dissipation and anti-collision facility system, including a track foundation 1, a track trough 11, a foundation side wall 12, a tank car 2, a buffer 21, a track 3, an energy dissipation wheel stop 31, an anti-collision beam 4, a rear support leg 41, an energy dissipation wheel stop 5, a front support leg 51, a combined spring 52, a column pier 6, and an embedded part 61.

[0026] Track 3 is arranged in track groove 11 on the top slab of the foundation. Energy dissipation wheel chocks 31 are located at the end section of track 3. The energy dissipation wheel chocks 31 are bolted together, and can still slide with damping on the top surface of track 3 after being clamped. Tank car 2 runs on track 3. A buffer 21 is provided at the front end of tank car 2, and a crash beam 4 is located behind track 3. The bottom of the crash beam 4 is provided with a rear support leg 41. The bottom surface of the rear support leg 41 contacts the top slab of the track foundation but is not fixed and can slide freely.

[0027] The horizontal top rod of the energy dissipation stop 5 is welded to the side of the anti-collision beam 4. A combined spring 52 is provided at the front end of the horizontal top rod of the energy dissipation stop 5. The combined spring 52 includes a single spring, a limit box and an end plate. There are multiple sets of single springs and they are located in the limit box. An end plate is provided at the front end of the spring set. A front support leg 51 is provided at the bottom of the energy dissipation stop 5. The bottom surface of the front support leg 51 is in contact with the foundation top plate but is not fixed and can slide freely. The column pier 6 is erected on the foundation side wall 12. An embedded part 61 is provided on the inner side of the column pier 6. The anti-collision beam 4 is connected to the embedded part 61. The bottom surface of the anti-collision beam 4 is suspended and isolated from the top plate of the track foundation 1.

[0028] In the event of an accident, as the tanker truck 2 slides forward, its wheels first contact the energy-dissipating wheel stop 31 on the track 3. The energy-dissipating wheel stop 31 initially dissipates a certain amount of kinetic energy from the tanker truck 2. As the tanker truck 2 continues to slide, its buffer 21 impacts the combined spring 52. The buffer 21 and the combined spring 52 further absorb the impact energy of the tanker truck 2. The energy-dissipating wheel stop 5 then transmits the remaining impact force to the crash beam 4. After the crash beam 4 deforms, it transmits the impact force to the end posts 6. The end posts 6 then transmit the impact force to the foundation sidewalls 11, thus completing the process of transmitting the impact effect. During the process of transmitting the impact force, the front support leg 51 and the rear support leg 41 at the bottom of the crash beam 4 and the energy-dissipating wheel stop 5 slide freely.

[0029] Preferably, the energy dissipation wheel stop 31 is as far away from the spring assembly 52 as possible, so that as much sliding energy is dissipated as possible.

[0030] Preferably, the anti-collision beam 4 has a hollow rectangular section or an H-shaped section, and the web of the anti-collision beam 4 is provided with a vertical stiffening plate at the position corresponding to the energy dissipation vehicle stop 5.

[0031] Preferably, the horizontal top rod of the energy dissipation vehicle stop 5 is a frustum-shaped, rectangular, or cylindrical steel structure with an appropriately reduced front end and the same width at the base as the anti-collision beam 4.

[0032] Preferably, the anti-collision beam 4 is connected to the inner embedded part 61 of the column pier 6 by welding or bolting.

[0033] Preferably, the concrete column pier 6 stands vertically on the side wall 12 of the track foundation. The column pier can also be a rectangular tube filled with concrete or a cast-in-place reinforced concrete structure.

[0034] In this embodiment, the implementation process of the anti-collision barrier structure is as follows:

[0035] First, after the main structure of the track foundation 1 below ground is completed, the column pier 6 is poured and the side embedded parts 61 are reserved.

[0036] Then, install the rear support leg 41 of the anti-collision beam 4, and then connect the anti-collision beam 4 to the aforementioned embedded part 61.

[0037] Then, install the energy dissipation barrier 5, connect the root of its horizontal top rod to the side of the above-mentioned anti-collision beam 4, and install the front support leg 51 of the energy dissipation barrier 5;

[0038] Finally, install the track 3, and then install the track top energy dissipation wheel stop 31. The energy dissipation wheel stop 31 is located at a certain distance in front of the aforementioned energy dissipation wheel stop 5.
