Description

Technical Field

[0001] This utility model relates to a stabilizing device for emergency rescue of derailed rail vehicles. It belongs to the technical field of vehicle derailment emergency rescue. Background Technology

[0002] When a rail vehicle needs to be lifted off the track, the wheelset needs to be raised to a certain height above the horizontal plane of the rail during the lifting process. There is a large gap between the bogie and the car body. The car body is lifted to a certain height first, and the bogie can only be lifted synchronously after the force-bearing surface contacts. This can result in the lifting height being too high. The tensile stress on the mechanical components of the bogie exceeds the limit, which will cause fatigue and failure. This is not conducive to the stability of the equipment and poses a hidden danger. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a rail vehicle derailment emergency rescue stabilization device that can reduce the gap between the bogie and the car body, significantly improve operational efficiency and safety, has a compact overall design, a stable structure, and is easy to operate.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An emergency rescue stabilization device for rail vehicle derailment is installed between the main body of the vehicle bogie and the main body of the vehicle center pin (the center pin is the connecting component between the car body and the bogie). There is a gap between the main body of the vehicle bogie and the main body of the vehicle center pin. From bottom to top, it includes a concave support block and a pad assembly to meet different gap requirements. The concave support block is concave in shape, made of iron, and weighs about 2KG. The pad assembly is installed on the left side and fixed with fixing bolts. Its function is to meet the requirements of different gaps. The pin is installed on the right side to prevent the device from shifting due to tilting or vibration.

[0006] There is a large gap at the connection between the bogie and the center pin of the car body. When the concave support block is inserted, the gap between the car body and the bogie can be reduced by the concave iron block. When the electric train car body rises, the bogie immediately rises synchronously, which can reduce the lifting height by about 10-20cm, thereby reducing the vehicle lifting height and effectively improving the environment in confined spaces, especially in subway tunnels.

[0007] Before the metro car is lifted as a whole, a stabilizing device is placed in the gap (between the bogie body and the center pin body, where the height is not fixed). The gap height is about 5-10cm. The fixed-size part can be installed first. If it is not enough, shims close to the gap height can be selected, about 3-4 shims are needed. After the gap height is filled, the excess shims can be rotated 180 degrees. The other side is fixed with pins to prevent the shims from moving. After the stabilizing device is placed, the bogie is lifted at the same time as the car is lifted. The lifting height can be reduced by about 10-20cm compared with conventional lifting. This not only solves the gap between the bogie and the car body, but also prevents the components from being subjected to greater upward tensile force. This prevents the performance of the components from deteriorating due to excessive upward stretching of the car body. It also avoids the upper part of the car body encroaching on the limit due to excessive height. The lower height and center of gravity can also improve the stability of the car. If the car derails, it provides convenience for rescue and improves the rescue speed.

[0008] The pad assembly includes multiple pads of different thicknesses that can rotate 360 ​​degrees and can be added or removed as needed to fit the gap between the vehicle bogie body and the vehicle center pin body.

[0009] The concave support block and the pad assembly are fixed by fixing bolts. The fixing bolts, from top to bottom, include an upper screw, a rotating block that matches the pad assembly, and a lower screw. The lower screw passes through the pad assembly and is fixed to the concave support block. The upper screw is fixed by a washer and a hexagonal nut.

[0010] A pin is also installed between the concave support block and the pad assembly to ensure the stability of the device during lateral movement or vibration.

[0011] The concave support block has an internal thread that matches the external thread of the lower screw. The pads have different thicknesses of 3cm, 2cm, 1cm, and 0.5cm. Multiple pads are provided with screw holes and pin holes. The concave support block has mounting holes that match the pins.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model relates to an emergency rescue stabilization device for rail vehicle derailment that can reduce the gap between the bogie and the car body. During the lifting process, the bogie can rise with the car body in the first instance, allowing operation within the height-restricted space, reducing the lifting height, avoiding the hidden danger of component fatigue leading to failure, and greatly improving operation efficiency and safety. The overall design is compact, the structure is stable, and it is easy to operate. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] This embodiment provides an emergency rescue stabilization device for rail vehicle derailment, such as... Figure 1-2 As shown, it is placed between the main body of the vehicle bogie and the main body of the vehicle center pin (the center pin is the connecting part between the car body and the bogie). There is a gap between the main body of the vehicle bogie and the main body of the vehicle center pin. From bottom to top, it includes a concave support block 1 and a pad assembly 3 to meet different gap requirements. The concave support block 1 is concave in shape, made of iron, and weighs about 2KG. The pad assembly 3 is installed on the left and fixed with fixing bolts 4. Its function is to meet the requirements of different gaps. The pin 2 is installed on the right to prevent the device from shifting due to tilting or vibration.

[0020] There is a large gap at the connection between the bogie and the center pin of the car body. When the concave support block 1 is inserted, the gap between the car body and the bogie can be reduced by the concave iron block. When the electric train car body rises, the bogie immediately rises synchronously, which can reduce the lifting height by about 10-20cm, reduce the vehicle lifting height, and effectively improve the environment in narrow spaces, especially in subway tunnels.

[0021] Before the metro car is lifted as a whole, a stabilizing device is placed in the gap (between the bogie body and the center pin body, where the height is not fixed). The gap height is about 5-10cm. The fixed-size part can be installed first. If it is not enough, shims close to the gap height can be selected, about 3-4 shims are needed. After the gap height is filled, the excess shims can be rotated 180 degrees. On the other side, pin 2 is used to fix shim 5 to prevent it from moving. After the stabilizing device is placed, the bogie is lifted at the same time as the car is lifted. The lifting height can be reduced by about 10-20cm compared with conventional lifting. This not only solves the gap between the bogie and the car body, but also prevents the components from being subjected to greater upward tensile force. This prevents the performance of the components from deteriorating due to excessive upward stretching of the car body. It also avoids the upper part of the car body encroaching on the limit due to excessive height. The lower height and center of gravity can also improve the stability of the car. If the car derails, it provides convenience for rescue and improves the rescue speed.

[0022] The pad assembly 3 includes multiple pads of different thicknesses that can rotate 360 ​​degrees and can be added or removed as needed to fit the gap between the bogie body and the center pin body of the vehicle. The gap between the bogie and the vehicle body is not fixed, and pads of different thicknesses are used to meet the needs of different gaps. Each pad has symmetrical holes, one end of which is a countersunk screw hole, which is used with the pin 2 to fix and prevent displacement.

[0023] The concave support block 1 and the pad assembly 3 are fixed by fixing bolts 4. The fixing bolts 4 include, from top to bottom, an upper screw 7, a rotating block 8 that matches the pad assembly 3, and a lower screw 9. The lower screw 9 passes through the pad assembly 3 and is fixed to the concave support block 1. The upper screw 7 is fixed with washers 5 of different sizes by washers 5 and hexagonal nuts 6.

[0024] A pin 2 is also installed between the concave support block 1 and the pad assembly 3 to ensure the stability of the device during lateral movement or vibration. The concave support block 1 is a concave semi-enclosed type, with the fixing bolt 4 closed on one side. It can be pushed in along the groove and fixed on the mounting base, allowing movement in only one direction. The movable pin 2 ensures that the device will not shift during lateral movement or vibration, ensuring the stability of the device. It can quickly position and fix the workpiece. Its design length is required to be greater than the height of the entire iron block body (including the height after adding the pad 5). It is designed in a countersunk form to match the countersunk hole of the pad 5. After installation, it can be kept on the same plane as the pad 5, without affecting the entire force-bearing surface and with an overall aesthetic appearance.

[0025] The concave support block 1 has an internal thread 11 that matches the external thread of the lower screw 9. The pads have different thicknesses of 3cm, 2cm, 1cm, and 0.5cm. Each of the pads has a screw hole 10 and a pin hole 13. The concave support block 1 has a mounting hole 12 that matches the pin 2.

[0026] This utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations will still fall within the protection scope of this utility model.
