Description

Technical Field

[0001] This utility model relates to a lateral movement device for rescuing heavy-duty railway metallurgical vehicles after they derail, and belongs to the technical field of railway vehicle rescue equipment. Background Technology

[0002] In recent years, with the increase in steel production capacity, the tonnage of metallurgical transport vehicles has also increased, from the early 60-ton and 100-ton models to the current 140-ton, 260-ton, and 320-ton models. Among them, the 320-ton torpedo-type mixed-rail vehicle, when fully loaded and including its own weight, has a total weight of 610 tons, with a total of 16 axles, and a single axle weight of about 38 tons (maximum 40 tons). These heavily loaded metallurgical vehicles are difficult to rescue after derailment, posing a great challenge to vehicle rescue and becoming a technical problem that plagues metallurgical enterprises.

[0003] Currently, steel companies use a combination of lifting and lateral reset devices to reset derailed vehicles during rescue operations. The lateral reset device uses a manually rotated screw to transmit thrust. During reset, the derailed vehicle is first lifted using the lifting device, then the screw of the lateral reset device is manually rotated. As the screw extends, it pushes one end of the lifted vehicle back to its original position directly above the rail. Finally, the lifting hydraulic device is lowered, completing the vehicle reset. However, due to the large tonnage of the torpedo tanker, two sets of screws are needed to provide lateral thrust during rescue operations. This is time-consuming and labor-intensive, and can even lead to screw bending and deformation, severely impacting the efficiency of vehicle rescue work. Therefore, improvement is essential. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rescue lateral movement device for railway vehicles that have derailed. This rescue lateral movement device can laterally move heavy-duty railway vehicles that have derailed. The lateral movement process is efficient, fast and stable, which can significantly shorten the rescue time, improve the efficiency of rescue work and reduce the workload of operators.

[0005] The technical solution to the above technical problem is:

[0006] A rescue lateral movement device for railway vehicle derailment includes a base, chains, grab hooks, a hydraulic cylinder, a manual hydraulic pump station, and high-pressure oil pipes. The base and the manual hydraulic pump station are placed on the railway foundation outside the derailed car. The rear ends of two chains are fixedly connected to the base, and the front ends of the two chains are connected to grab hooks, which hook onto the rails. The rear end of the hydraulic cylinder is connected to the base, and the hydraulic cylinder is connected to the manual hydraulic pump station through a high-pressure oil pipe. The front end of the hydraulic push rod of the hydraulic cylinder presses against the side wall of the derailed car.

[0007] The aforementioned rescue lateral movement device for railway vehicle derailment comprises a base plate, a support plate, a connecting plate, a pin, a fixing ring, and a round pin. The base plate is a square plate, with two support plates welded vertically and parallel to the upper surface of the base plate. The connecting plate is welded vertically between the two support plates. The upper ends of the two support plates each have U-shaped grooves, and the two ends of the pin are respectively embedded in the U-shaped grooves. The two ends of the pin are rotatably engaged with the U-shaped grooves. The lower end of the hydraulic cylinder has a pin hole, and the middle part of the pin is rotatably connected to the pin hole at the lower end of the hydraulic cylinder. Fixing rings are welded to both sides of the front end of the base plate, and the rear ends of the two iron chains are respectively connected to the two fixing rings through round pins.

[0008] The aforementioned railway vehicle derailment rescue lateral movement device has an L-shaped grab hook at the front end of the chain. The rear end of the L-shaped grab hook is connected to the chain, and the front end of the L-shaped grab hook has an inwardly curved hook. The shape of the L-shaped front end and the curved hook matches the top surface and side wall of the rail head. The L-shaped front end and the curved hook are locked inside the rail head.

[0009] The beneficial effects of this utility model are:

[0010] In this invention, the base support plate is connected to the hydraulic cylinder via a pin. The front end of the chain hooks onto one side of the rail. The base is tightened to the rail via the chain and hooks, preventing displacement between the base and the rail and providing support for the hydraulic cylinder's pushing action. The hooks at the front end of the chain are L-shaped and curved, which can firmly hook onto one side of the rail head, preventing slippage. The hydraulic cylinder is rotatably connected to the base support plate via a pin, allowing for real-time adjustment of the cylinder's angle to ensure stable pushing action.

[0011] This utility model has a simple structure and is easy to use. It can be used for lateral movement rescue of derailed heavy-duty railway metallurgical vehicles. The lateral movement process is efficient, fast and stable, which significantly shortens the rescue time, improves the efficiency of the rescue work, reduces the workload of the operators, and ensures the smooth progress of the derailed vehicle rescue work.

[0018] Figure 1 The display shows that the base 1 and the manual hydraulic pump station 5 are placed on the railway foundation. The rear end of the cylinder body of the hydraulic cylinder 4 is connected to the base 1. The hydraulic cylinder 4 is connected to the manual hydraulic pump station 5 through the high-pressure oil pipe 6. The manual hydraulic pump station 5 provides high-pressure hydraulic oil to the hydraulic cylinder 4, driving the hydraulic push rod of the hydraulic cylinder 4 to extend and push the derailed car 16 to move laterally.

[0019] Figure 1 , 2 As shown in Figure 3, the base 1 consists of a base plate 7, a support plate 8, a connecting plate 9, a pin 11, a fixing ring 12, and a round pin 13. The base plate 7 is a square plate. Two support plates 8 are welded vertically and parallel to the upper surface of the base plate 7. The connecting plate 9 is welded vertically between the two support plates 8, connecting them as a whole to ensure the stability of the support plates 8. The upper ends of the two support plates 8 each have U-shaped grooves 10. The two ends of the pin 11 are embedded in the U-shaped grooves 10, and the two ends of the pin 11 are rotatably engaged with the U-shaped grooves 10. The lower end of the hydraulic cylinder 4 has a pin hole. The middle part of the pin 11 is rotatably connected to the pin hole at the lower end of the hydraulic cylinder 4.
