[0001] This utility model relates to the field of rail emergency vehicle technology, specifically a bidirectional telescopic portable rail emergency vehicle. Background Technology
[0002] Rail emergency vehicles are vehicles specifically designed for emergency rescue in rail transit accidents. They can quickly reach the scene and provide medical assistance and other emergency rescue services. These vehicles are typically equipped with various rescue equipment and tools, enabling them to provide rapid rescue services when trains malfunction or are involved in accidents, ensuring the safety of passengers and trains. In existing technology, rail emergency vehicles mainly consist of a frame and rail wheels. During use, the rail wheels are driven to rotate relative to the rail by a drive component, which moves the frame and the rescue equipment and tools on its surface. However, many electric rail vehicles are integral structures that occupy a large amount of space, making them inconvenient to move onto the rails in practical applications, thus affecting the efficiency of rail emergency rescue. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] Please see Figures 1-4 This embodiment provides a technical solution: a bidirectional telescopic portable rail emergency vehicle, including an emergency vehicle frame 1;
[0021] Emergency vehicle frame 1: It includes a body 101, slide rail 102, frame 103, frame 2 104, support plate 105 and slide rail 2 106. The body 101 has two slide rails 102 at both the left and right ends. The frame 103 is located at the front of the body 101. The frame 103 has drive wheels 2 at both the left and right ends. The drive wheels 2 are all 36V 4-inch hub motors, which provide power for the movement of the whole device. The electronic control system can make the two motors rotate at the same speed through the Hall control lever. When in use, the frame 2 104 and the driven wheel 3 are located at the front, facing the direction of travel.The first frame 103 and the drive wheel 2 are located at the rear, with the drive wheel 2 providing propulsion. The second frame 104 is located at the rear of the body 101. Both ends of the second frame 104 are equipped with driven wheels 3, providing support for the rear end of the rail emergency vehicle. The first frame 103 and the second frame 104 are staggered vertically. Both ends of the cross plates of the first frame 103 and the second frame 104 are equipped with support plates 105. The surface of each support plate 105 is equipped with a second slide rail 106. The second slide rail 106 is longitudinally slidably connected to the corresponding longitudinal slide rail 102. Through the relative sliding of the first slide rail 102 and the second slide rail 106, the first frame 103 and the second frame 104 are moved towards the body 101, causing the overall device to retract, reducing the space occupied, and facilitating the carrying of the entire device. The vehicle body 101, frame one 103, and frame two 104 are all lightweight aluminum alloy frames. The rail emergency vehicle uses argon arc welding and riveting to maximize mechanical strength. The emergency vehicle frame 1 also includes limiting frame plates 107, which are respectively set in the middle of the horizontal plates of frame one 103 and frame two 104. The vertical plates in the middle of the vehicle body 101 are located inside the adjacent limiting frame plates 107. The vertical plates in the middle of the vehicle body 101 limit the movement range of the limiting frame plates 107, preventing frame one 103 and frame two 104 from detaching from the vehicle body 101. The left and right ends of the limiting frame plates 107 are equipped with sliders 4, and the left and right ends of the vehicle body 101 are equipped with slide rails 5. The sliders 4 are longitudinally slidably connected to the slide rails 5 corresponding to the longitudinal positions. The longitudinal sliding of slider 4 and slide rail 5 provides guiding support for the movement of frame 103 and frame 204, while enhancing the load-bearing capacity and mechanical strength of the overall device, enabling it to carry a load of over 300 kg. Handles 6 are provided on both the left and right ends of the upper surface of the vehicle body 101 for easy lifting of the entire device. Threaded holes 7 are provided on the surface of the support plate 105, and locking pins 8 are laterally slidably connected inside each threaded hole 7. The semi-circular ends of the locking pins 8 pass through through holes on the surface of slide rail 206 and are inserted into locking holes on the surface of slide rail 102. A stud 9 is provided at the end of the locking pin 8 away from the vehicle body 101. Rotating the stud 9 disengages it from the threaded hole 7 through the threaded connection between the stud 9 and the threaded hole 7. The locking pin 8 can be pulled out from the locking hole on the surface of slide rail 102, thus removing the limiting relationship between slide rail 102 and slide rail 2 106. Similarly, by threading the stud 9 to the corresponding threaded hole 7, the locking pin 8 is inserted into the locking hole on the surface of slide rail 102, locking the relative sliding of slide rail 102 and slide rail 2 106. Springs 10 are movably fitted onto the outer arc surface of the locking pin 8. The end of the spring 10 closest to the vehicle body 101 is fixedly connected to the inner wall of the adjacent threaded hole 7. Under the elastic force of the spring 10, a force is applied to the stud 9, preventing the stud 9 from easily entering the threaded hole 7, and simultaneously making the threaded connection between the stud 9 and the threaded hole 7 more secure. A knob 11 is provided at the end of each stud 9 for easy rotation.
[0022] The working principle of the bidirectional telescopic portable rail emergency vehicle provided by this utility model is as follows: In use, the entire device is placed on the rail. The second frame 104 and the driven wheel 3 are located at the front, facing the direction of travel; the first frame 103 and the drive wheel 2 are located at the rear. Both drive wheels 2 are hub motors. By controlling the hub motors to start, power is provided for the movement of the entire device. When the entire device is moved without a rail, simply rotate the stud 9 by turning the knob 11. Through the threaded connection between the stud 9 and the threaded hole 7, the stud 9 is disengaged from the thread. Hole 7, at this time, the locking pin 8 can be pulled out from the locking hole on the surface of slide rail 102, canceling the limit between slide rail 102 and slide rail 2 106. Through the relative sliding of slide rail 102 and slide rail 2 106, the frame 103 and frame 2 104 are moved towards the vehicle body 101, so that the overall device is retracted and the space occupied is reduced. At the same time, the stud 9 is rotated, and through the threaded connection between the stud 9 and the corresponding threaded hole 7, the locking pin 8 is inserted into the locking hole on the surface of slide rail 102, locking the relative sliding of slide rail 102 and slide rail 2 106.
[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
