Description

Technical Field

[0001] This utility model belongs to the field of engineering equipment technology, and specifically relates to a vehicle turning device. Background Technology

[0002] During the construction of single-track railway tunnels, the limited tunnel cross-sectional dimensions (typically only about 6 meters wide) present significant technical challenges to the traffic management of small vehicles (such as command vehicles and engineering inspection vehicles, approximately 5.2 meters in length) within the construction area. Due to the narrow tunnel space, dim lighting, and complex working environment, vehicles face the following key issues when performing U-turns within the tunnel: 1. High safety risks: Visibility is obstructed inside the tunnel, making it difficult for drivers to accurately judge the location of surrounding obstacles. This greatly increases the risk of vehicle scraping or collisions during U-turns, threatening the safety of personnel and equipment.

[0003] 2. High operational difficulty: The existing U-turn method relies entirely on the driver's skills, requiring multiple forward-reverse cycles and significant steering wheel adjustments in an extremely narrow space. This demands extremely high driving skills, and ordinary construction workers have a high error rate.

[0004] 3. Inefficiency: A single U-turn takes too long (usually more than 5 minutes) and requires frequent gear shifting and steering, which seriously affects the construction progress, especially in large-scale inspections, observations or emergency dispatch scenarios, becoming a bottleneck.

[0005] 4. Poor spatial adaptability: When construction materials, equipment or temporary facilities are piled up in the tunnel, the effective passage width is further reduced, and traditional U-turn methods are completely ineffective, forcing vehicles to drive a long distance back out of the tunnel, which greatly reduces the efficiency of material transfer and personnel dispatch.

[0006] Currently, the industry generally uses a primitive U-turn method involving manual direction and multiple turns, and there is no dedicated equipment to solve the above problems. Therefore, there is an urgent need to develop a compact and easy-to-operate mechanized U-turn device to improve the safety, efficiency, and spatial adaptability of tunnel construction vehicle dispatching. Utility Model Content

[0007] The purpose of this utility model is to provide a vehicle turning device, thereby solving the problem that turning around vehicles is inconvenient due to the limited tunnel cross-sectional dimensions during single-track railway tunnel construction. The specific technical solution is as follows: A vehicle turning device includes a guide ramp, a rotating platform, a drive unit, a track base, a first roller, and a control panel. The guide ramp is installed on both sides of the track base, and the line connecting the guide ramps passes through the center of the track base. The first roller is installed at the bottom of the rotating platform and rolls on a circular track. The drive unit is installed at the center of the circular track and is connected to the rotation center of the rotating platform. The control panel is located on one side of the track base and is electrically connected to the drive unit.

[0008] Preferably, the track base is composed of multiple annular tracks with the same center but different diameters, and connecting rods are installed between the annular tracks. Multiple sets of first rollers corresponding to the multiple annular tracks are installed at the bottom of the rotating platform.

[0009] Preferably, multiple jacks for adjusting height are evenly installed at the bottom of the guide ramp and the track base.

[0010] Preferably, the jack includes a movable part and a fixed part, the fixed part is mounted on the guide ramp and the track base, and the movable part is equipped with a support pad.

[0011] Preferably, it further includes an auxiliary fixing unit, which is installed on the guide ramp for decelerating and fixing the rotating platform. The auxiliary fixing unit includes a magnet, an electromagnet, a telescopic shaft, and a friction plate. The guide ramp includes an inclined section and a connecting section. The connecting section is connected to the track base. A movable groove is formed on the side wall of the connecting section near the track base. The telescopic shaft is slidably installed in the movable groove. The electromagnet is installed at the bottom of the movable groove. The magnet is installed at the end of the telescopic shaft near the electromagnet. The magnetic field directions of the magnet and the electromagnet are the same. The electromagnet is made of soft iron. The friction plate is installed at the end of the telescopic shaft near the rotating platform.

[0012] Preferably, the inclined surface is provided with an array of anti-slip textures, and the two sides of the rotating platform are provided with vibration markings for vehicle movement.

[0013] Preferably, the track base is composed of multiple modules, and the inclined platform and rotating platform are detachably connected to the track base.

[0014] Compared with existing technologies, this utility model has the following beneficial effects: 1. This utility model involves placing a rotating platform on a track base via a first roller, and then driving the rotating platform to rotate, thereby turning the vehicle on the platform 180 degrees for a U-turn. Compared to drivers turning vehicles manually, this not only improves work efficiency but also avoids vehicle scratches or collisions during the U-turn process, thus enhancing safety.

[0015] 2. This utility model uses an auxiliary fixing unit to decelerate the rotating platform during rotation and to fix the stationary rotating platform. When the rotating platform is about to rotate 180 degrees, the electromagnet is activated. The magnetic field generated by the electromagnet is in the same direction as the magnetic field of the magnet, so a repulsive force is generated between them. The repulsive force pushes the telescopic shaft to move closer to the rotating platform until the friction plate contacts the rotating platform and generates friction. The friction force decelerates the rotating platform and avoids the inertia of the rotating platform affecting the drive unit. At the same time, the static friction between the friction plate and the rotating platform can improve the stability of the vehicle when it moves onto the rotating platform.

Detailed Implementation

[0022] 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.

[0023] Next, refer to Figures 1 to 4The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: A vehicle turning device includes a guide ramp 1, a rotating platform 2, a drive unit 3, a track base 5, a first roller 4, and a control panel. The guide ramp 1 is bolted to both sides of the track base 5, and the line connecting the guide ramps 1 passes through the center of the track base 5. The first roller 4 is mounted on the bottom of the rotating platform 2 and rolls on the circular track, providing support to the rotating platform 2. The drive unit 3 is mounted at the center of the circular track and includes a motor and a reducer, both mounted on the track base 5. One end of the reducer is connected to the motor, and the other end is connected to the rotation center of the rotating platform 2. The control panel is located on one side of the track base 5 and is electrically connected to the drive unit 3. The operator can start the motor via the control panel; each start of the motor rotates the rotating platform 2 180 degrees. In use, the driver drives the engineering vehicle through the guide ramp 1 to the rotating platform 2. Then, the staff starts the motor through the control panel. The motor drives the rotating platform 2 to rotate through the reducer. During this process, the first roller 4 will move around the center of the track base 5 on the track base 5. When the rotating platform 2 rotates 180 degrees, the engineering vehicle completes the turnaround, the motor is turned off, and the driver drives the engineering vehicle away from the rotating platform 2 after the rotating platform 2 comes to a stop.

[0024] The track base 5 consists of multiple concentric annular tracks 501 with different diameters. Multiple sets of first rollers 4, corresponding to the annular tracks 501, are installed at the bottom of the rotating platform 2. By adding annular tracks 501 and first rollers 4, the load-bearing capacity and stability of the rotating platform 2 can be improved, thus enhancing the practicality of this application. Connecting rods 502 are installed between the annular tracks 501 to enhance the stability between them.

[0025] Multiple jacks for height adjustment are evenly installed at the bottom of the guide ramp 1 and the track base 5. These jacks are located inside the guide ramp 1 and the track base 5, ensuring no interference when placed on flat ground. In uneven or sloping locations, workers can adjust the extension length of the jacks according to the terrain during installation of the track base 5 and the guide ramp 1, ensuring both receive sufficient support and guaranteeing the stability of this application.

[0026] The jack includes a moving part and a fixed part. The fixed part is installed on the guide ramp 1 and the track base 5 by bolts. The moving part is equipped with a support pad, which can distribute the pressure of the jack. While improving the overall stability of this application, it can also prevent the jack from damaging the road surface.

[0027] The track base 5 is composed of multiple modules. The inclined platform and the rotating platform 2 are detachably connected to the track base 5. The track base 5 is modularly designed. At the same time, the rotating platform 2 and the inclined platform 1 are also detachably connected, which makes the whole application easy to assemble, disassemble and transport. It can be quickly transferred to the required place for use, improving the convenience of use.

[0028] The inclined surface 101 is arrayed with anti-slip textures 11 to prevent vehicles from slipping during operation, especially in humid working environments. Vibration markings 12 are installed on both sides of the rotating platform 2 to control vehicle movement. When a construction vehicle runs over a vibration marking 12, the marking 12 will emit a sound, and the vehicle will vibrate, alerting the driver that the vehicle is approaching the edge of the rotating platform 2. This prevents driver error from causing the vehicle to deviate from the rotating platform 2, potentially leading to the vehicle overturning or getting stuck on the track base 5.

[0029] The auxiliary fixing unit includes a magnet 6, an electromagnet 7, a telescopic shaft 8, and a friction plate 9. The guide ramp 1 includes an inclined section 101 and a connecting section 102, which is connected to the track base 5 by bolts. A movable groove 10 is formed on the side wall of the connecting section 102 near the track base 5. The telescopic shaft 8 is slidably installed in the movable groove 10, and the electromagnet 7 is bolted to the bottom of the movable groove 10. The electromagnet 7 is electrically connected to the control console. The magnet 6 is installed at the end of the telescopic shaft 8 near the electromagnet 7, and the friction plate 9 is installed at the end of the telescopic shaft 8 near the rotating platform 2. Since the magnetic fields of the magnet 6 and the electromagnet 7 are in the same direction, a repulsive force is generated between them. When the rotating platform 2 is about to rotate 180 degrees, the electromagnet 7 is activated, and the repulsive force pushes the telescopic shaft 8 towards the rotating platform 2 until the friction plate 9 contacts the rotating platform 2, generating friction. This friction decelerates the rotating platform 2, preventing the inertia of the rotating platform 2 from affecting the drive unit 3. Meanwhile, the static friction between the friction plate 9 and the rotating platform 2 can improve the stability of the vehicle during its journey onto the rotating platform 2. When the drive unit 3 is activated, the electromagnet 7 is deactivated, and the magnetic field of the electromagnet 7 disappears. At this time, since the electromagnet 7 is made of soft iron, the magnet 6 and the soft iron will attract each other, so the telescopic shaft 8 will move towards the electromagnet 7 until the magnet 6 and the electromagnet 7 are in contact. At this time, the telescopic shaft 8 and the friction plate 9 are completely located within the movable groove 10 and will not interfere with the rotating platform 2.
