[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a rescue device for a double-track bridge, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a motor vehicle 1, a double track bridge 2, a rotating assembly 3, a lifting assembly 5, a transverse hydraulic cylinder 6, and a jack 7.

[0028] The double-track bridge 2 is installed on the motor vehicle 1.

[0029] The rotating component 3 is mounted on the motor vehicle 1. The rotating component 3 is used to drive the double track bridge 2 to rotate so that the double track bridge 2 is perpendicular to the track 4.

[0030] The lifting component 5 is mounted on the rotating component 3. The lifting component 5 is used to drive the double rail bridge 2 to descend so that the double rail bridge 2 falls onto the track 4.

[0031] The transverse hydraulic cylinder 6 is placed on the double track bridge 2, and the transverse hydraulic cylinder 6 is used to support the railcar.

[0032] The jack 7 is placed on the ground and is used to lift the railcar so that the railcar falls onto the transverse hydraulic cylinder 6.

[0033] In use, the rerail bridge 2 is pre-installed on the motor vehicle 1, allowing for rapid access to the derailment site without the need for additional lifting equipment. The rotating assembly 3 drives the rerail bridge 2 to rotate horizontally, aligning it vertically with the track 4. The lifting assembly 5 drives the rerail bridge 2 to descend vertically, smoothly placing it at a predetermined position between the two tracks 4. Jacks 7 lift the derailed railcar to a certain height, detaching its wheels from ground obstacles. A lateral movement cylinder 6, installed on the rerail bridge 2, has its piston rod in contact with the bottom of the railcar, hydraulically pushing the railcar laterally to gradually return the wheelset to its normal track 4 position, completing the rerailing process.

[0034] In this invention, the double-track bridge 2 is pre-installed on the motor vehicle 1, which utilizes the mobility of the motor vehicle 1 to quickly reach the derailment site without the need for additional hoisting equipment, thus improving construction efficiency and reducing construction costs.

[0035] To drive the lifting and lowering of the double-track bridge 2, please refer to... Figure 1 In a preferred embodiment, the lifting assembly 5 includes an electric push rod, which is mounted on the vehicle 1, and the output shaft of the electric push rod is connected to the fixed end of the rotating assembly 3.

[0036] When in use, when the output shaft of the electric push rod extends, it pushes the fixed end of the rotating component 3 to move upward, thereby causing the rotating end of the rotating component 3 and the double rail bridge 2 installed on the rotating end to rise synchronously, realizing the lifting action of the double rail bridge 2 so as to avoid ground obstacles during transportation or rotation adjustment. When the output shaft retracts, it pulls the fixed end of the rotating component 3 to move downward, causing the double rail bridge 2 to fall synchronously until the bottom of the double rail bridge 2 contacts and falls to the predetermined position on the track 4, completing the placement of the double rail bridge 2.

[0037] To drive the double-track bridge 2 to rotate, please refer to... Figure 1 In a preferred embodiment, the rotating assembly 3 includes a motor, the output shaft of the electric push rod is connected to the motor, and the output shaft of the motor is connected to the double-track bridge 2.

[0038] During use, when the double-track bridge 2 needs to be switched from transport mode to working mode, the electric push rod first raises the motor and double-track bridge 2 as a whole to a preset height to avoid interference between the double-track bridge 2 and the vehicle 1 or the ground during rotation. Then, the motor starts, driving the double-track bridge 2 to rotate 90° until the guide beam of the double-track bridge 2 is perpendicular to the direction of track 4. Finally, the electric push rod drives the double-track bridge 2 to descend, allowing it to land on track 4 and complete its positioning. After the rescue is completed, the motor drives the double-track bridge 2 to rotate 90° in the opposite direction to reset, and the electric push rod lifts it up, allowing it to be transported away with the vehicle 1.

[0039] To reduce the possibility of misalignment of the double-track bridge 2, please refer to... Figure 2 In a preferred embodiment, the rescue device further includes a limiting clamp 21, which is connected to the double track bridge 2 and clamps onto the track 4.

[0040] During use, after the double-track bridge 2 is positioned, the limiting clamp 21, under its own pre-tightening force, tightly clamps the rail head of the track 4. The tight fit between the arc-shaped groove and the rail head restricts the horizontal displacement of the double-track bridge 2, ensuring that the guide beam of the double-track bridge 2 and the track 4 always maintain precise alignment.

[0041] To ensure a tighter fit between the limiting clamp 21 and the track 4, please refer to... Figure 2 In a preferred embodiment, the rescue device further includes an elastic layer 22, which is connected to the limiting clamp on the side near the track 4.

[0042] When in use, the elastic layer 22 is made of rubber material with a thickness of 3mm. When the limiting clamp 21 clamps the rail 4, the elastic layer 22 is deformed by the pressure of the rail head, filling the tiny gap between the limiting clamp 21 and the rail head, and avoiding local stress concentration that could cause wear on the rail head or clamp.

[0043] For easier transfer of the double-track bridge 2, please refer to... Figure 1 In a preferred embodiment, the double-track bridge 2 includes a fixing component 23 and a plurality of bridge bodies 24. The output shaft of the motor is connected to one of the bridge bodies 24. The plurality of bridge bodies 24 are connected end to end in sequence. The fixing component 23 is used to fix adjacent bridge bodies 24.

[0044] During use and rescue operations, multiple bridge sections 24 are connected end-to-end in sequence, and then the fixing components 23 are used to secure adjacent bridge sections 24. After the rescue is completed, the fixing components 23 are released, and the bridge sections 24 can be disassembled. The assembly and disassembly are convenient, facilitating the transfer of the double-track bridge 2.

[0045] To reduce the weight of double-track bridge 2, please refer to... Figure 1 In a preferred embodiment, the bridge body 24 is provided with weight reduction holes 25.

[0046] In use, the design of the weight-reducing hole 25, through structural optimization, significantly reduces the weight of the bridge body 24 while maintaining sufficient strength and functionality, achieving multi-dimensional improvements in portability, economy and safety.

[0047] To connect adjacent bridge sections 24 together, please refer to... Figure 1 In a preferred embodiment, the fixing component 23 includes a plurality of bolts 231, nuts 232 and connecting plates 233. Two connecting plates 233 respectively abut against the two sides of adjacent bridge bodies 24. A plurality of bolts 231 are inserted between the two connecting plates 233 and are respectively inserted on adjacent bridge bodies 24. Nuts 232 are threaded to the ends of bolts 231 and abut against connecting plates 233.

[0048] In use, the two connecting plates 233 are respectively attached to both sides of the mating joint of adjacent bridge bodies 24 to ensure even distribution of connection force. The bolt holes 231 on the connecting plates 233 correspond one-to-one with the pre-set through holes at the mating joint of the bridge bodies 24. Multiple bolts 231 pass through one side of the connecting plate 233, the mating through hole of the adjacent bridge body 24, and the other side of the connecting plate 233 in sequence to form a through connection. By tightening the nut 232 at the end of the bolt 231 with a wrench, after the nut 232 is tightly attached to the surface of the connecting plate 233, torque is continued to be applied, causing the bolt 231 to generate axial tension, which drives the two connecting plates 233 on both sides to tighten towards the middle, firmly clamping the mating surfaces of the adjacent bridge bodies 24. When it is necessary to disassemble the bridge body 24, the nut 232 is rotated in the opposite direction to release the preload, and after the bolt 231 is pulled out, the connecting plate 233 separates from the bridge body 24, and the adjacent bridge bodies 24 can be directly disassembled.

[0049] To improve the efficiency of installing bolt 231, please refer to... Figure 1 In a preferred embodiment, the fixing component 23 further includes a guide cylinder 234, which is connected inside the bridge body 24 and through which the bolt 231 passes.

[0050] When in use, the guide tube 234 acts as a rigid channel to guide the bolt 231 to pass through quickly, avoiding the head of the bolt 231 from hitting the edge of the hole.

[0051] To enable vehicle 1 to travel between the two tracks 4, please refer to... Figure 1 In a preferred embodiment, the motor vehicle 1 is a tracked vehicle, and the width of the tracked vehicle is less than the distance between the two tracks 4.

[0052] When in use, the tracked vehicle is narrower than the spacing between tracks 4, allowing it to travel or park stably within the gap between the two tracks 4. In areas with limited space, such as around tracks 4, the narrower tracked vehicle can turn and adjust its position flexibly. Especially during rerailment rescue, it can accurately park under the disabled vehicle or next to the rerail bridge 2, reducing operational delays caused by insufficient space.

[0053] To better understand this utility model, the following is combined with... Figure 1 - Figure 2The working principle of the rerailing device 2, a rerailing bridge, is described in detail below: The rerailing bridge 2 is pre-installed on a motor vehicle 1, allowing it to quickly reach the derailment site without the need for additional lifting equipment. A rotating component 3 drives the rerailing bridge 2 to rotate horizontally, aligning it vertically with the track 4. A lifting component 5 drives the rerailing bridge 2 to descend vertically, placing it smoothly at a predetermined position between the two tracks 4. A jack 7 lifts the derailed railcar to a certain height, detaching its wheels from the ground obstacle. A lateral movement cylinder 6 is installed on the rerailing bridge 2, with its piston rod contacting the bottom of the railcar. Hydraulic drive pushes the railcar laterally, gradually returning the wheelset to its normal track 4 position, completing the rerailing process.

[0054] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
