[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0033] Reference Figure 1 This embodiment provides a vehicle evacuation platform 100, which is specifically designed to quickly receive and remove faulty or burning vehicles during vehicle testing and other working conditions. The vehicle evacuation platform 100 includes a moving beam 101, a central beam 102, an assembly 103, a front guide roller 104, a rear guide roller 105, a front wheel plate 106, and a rear wheel plate 107.

[0034] The movable beam 101 is located on both sides of the central beam 102. The central beam 102 and the movable beam 101 are connected by an assembly 103, which includes a front guide roller 104, a rear guide roller 105, a front wheel plate 106, and a rear wheel plate 107.

[0035] The vehicle's wheelbase A is the same as the wheelbase B between the front guide roller 104 and the rear guide roller 105. The front wheel plate 106 and the rear wheel plate 107 are located on the same side of the front guide roller 104 and the rear guide roller 105. The distance between the front wheel plate 106 and the front guide roller 104 is the same as the distance between the rear wheel plate 107 and the rear guide roller 105.

[0036] The outer circumferential surfaces of the front guide roller 104 and the rear guide roller 105, together with the upper surfaces of the front wheel plate 106 and the rear wheel plate 107, form a continuous surface M for supporting or guiding an object.

[0037] Specifically, to ensure the platform can accurately and synchronously support the front and rear wheels of the vehicle, the wheelbase B between the front guide roller 104 and the rear guide roller 105 is designed to be consistent with the wheelbase A of the vehicle under test. Simultaneously, the front wheel plate 106 and the rear wheel plate 107 are located on the same side of the front guide roller 104 and the rear guide roller 105, for example, both located behind the traveling guide rollers, and the relative distance between the front wheel plate 106 and the front guide roller 104 is the same as the relative distance between the rear wheel plate 107 and the rear guide roller 105.

[0038] Preferably, the highest point of the outer circumferential surface of the front guide roller 104 and the rear guide roller 105 is on the same plane in terms of horizontal height as the upper surface of the front wheel plate 106 and the rear wheel plate 107, thus forming a continuous surface M for supporting or guiding an object.

[0039] When the vehicle evacuation platform 100 is towed to the area under the vehicle, the vehicle tires first contact the front guide rollers 104 and the rear guide rollers 105, and then smoothly roll along the circumference of the guide rollers onto the front wheel plate 106 and the rear wheel plate 107. This effectively avoids severe bumps or jamming of the vehicle during the process of entering the platform from a stationary state, ensuring that in emergency evacuation (such as in a fire environment), the vehicle can be transferred from the hub station to the vehicle evacuation platform 100 in the shortest time and with the most stable trajectory, greatly improving the safety and response efficiency of the evacuation.

[0040] Furthermore, to ensure the vehicle evacuation platform 100 is compatible with various test vehicles with different wheelbases on the market, the moving beam 101 adopts a modular telescopic and adjustable design. Through the adjustment sleeve, precise and controlled adjustment of the distance between the front and rear wheel arches is achieved.

[0041] An adjusting sleeve is fitted onto the outer surface of the movable beam 101. The inner wall of the adjusting sleeve is precision machined to ensure that it can slide freely along the outer diameter axial direction of the movable beam 101. This sliding fit allows the rear wheel plate 107 to be horizontally displaced relative to the front wheel plate 106, thereby dynamically changing the center distance between the two sets of bearing grooves 108.

[0042] To lock the position after adjustment, the system uses high-strength bolts for limiting and fixing. The surface of the moving beam 101 can be pre-drilled with a series of limiting holes (discrete type) according to the wheelbase of common vehicle models, or it can be combined with the positioning groove through friction (continuous type). After the adjusting sleeve slides to the target position, the adjusting sleeve and the moving beam are firmly locked by tightening the bolts.

[0043] Reference Figure 2Both the front wheel plate 106 and the rear wheel plate 107 are provided with grooves 108. A first inclined surface 108a is provided on the side of the groove 108 that is close to the continuous surface M. The first inclined surface 108a is inclined in the direction close to the continuous surface M. A second inclined surface 108b is provided on the side of the groove 108 that is away from the continuous surface M. The second inclined surface 108b is inclined in the direction away from the continuous surface M.

[0044] The front wheel arch 106 and the rear wheel arch 107 are both provided with grooves 108 for defining the position of the vehicle tires. The grooves 108 form a sunken accommodating space on the travel trajectory of the continuous surface M, which is designed to lock the front and rear wheels of the vehicle in preset positions and prevent the vehicle from moving longitudinally during the high-speed removal of the platform.

[0045] A first inclined surface 108a is provided on the side of the groove 108 near the continuous surface M, i.e., the vehicle entry end. The first inclined surface 108a extends upward in a direction close to the continuous surface M, thereby forming a gentle transition ramp between the continuous surface M and the bottom of the groove 108. When the vehicle tire transitions from the continuous surface M formed by the front guide roller 104 or the rear guide roller 105 to the wheel plate, the first inclined surface 108a can guide the tire.

[0046] A second inclined surface 108b is provided on the side of the groove 108 away from the continuous surface M (i.e., the front edge of the vehicle). The second inclined surface 108b is inclined upward in the direction away from the continuous surface M. The second inclined surface 108b cooperates with the first inclined surface 108a to jointly outline the cross-sectional profile of the groove 108.

[0047] The main function of the second inclined surface 108b is to limit and block: when the vehicle evacuation platform 100 is subjected to traction force (such as winch pulling force) and generates a large acceleration, the second inclined surface 108b can act as a physical barrier to hold the tires in place, preventing the vehicle from rushing off the wheel plate due to inertia. At the same time, the V-shaped or U-shaped groove structure formed by the first inclined surface 108a and the second inclined surface 108b together can use the vehicle's own weight to achieve automatic centering and positioning, ensuring that in an emergency, the vehicle can be stably supported in the central area of ​​the vehicle evacuation platform 100 without manual intervention, providing necessary safety for subsequent high-speed evacuation.

[0048] Furthermore, if the tire only contacts the bottom plane of the groove 108, due to the enormous weight of the test vehicle, all the gravitational pressure will be highly concentrated in a very small contact area. This extremely high local pressure, under the impact load of long-term repeated use or emergency evacuation, can easily cause the center area of ​​the wheel plate to dent. Once the bottom surface of the wheel plate dents and deforms due to excessive force, it may rub against the ground or guide rails when the platform is traction-driven, increasing running resistance and even causing the platform to jam. However, through the cooperation of the first inclined surface 108a and the second inclined surface 108b, the circumferential surface of the tire forms multi-point or surface contact with the inclined surface and the groove 108, transforming the originally concentrated vertical pressure into a dispersed pressure distributed along the inclined surface, achieving a uniform distribution of load on the wheel plate. This optimized stress structure not only prevents wheel plate denting but also ensures a stable and safe clearance between the bottom of the platform and the ground, extending the service life of the equipment.

[0049] Reference Figure 2 The top of the second inclined surface 108b is provided with a convex surface 108c. The height H between the convex surface 108c and the ground is greater than the distance L between the top of the continuous surface M and the ground. A guide surface 108d is provided on one side of the convex surface 108c. The guide surface 108d is inclined towards the ground.

[0050] When the vehicle evacuation platform 100 is towed and moves at high speed or performs emergency braking, the convex surface 108c, due to its physical height above the bearing plane, can generate a stronger mechanical blocking effect, preventing the vehicle from falling off due to huge inertial force and ensuring the synchronous displacement of the vehicle and the platform.

[0051] When the vehicle is being tested, the front wheels need to pass over the rear wheel arch 107. Therefore, the guide surface 108d is designed primarily to facilitate the smooth passage of the vehicle over the rear wheel arch 107. The guide surface 108d provides a gradual guiding path for the tire. Since the convex surface 108c has a certain height H, without the transition provided by the guide surface 108d, the tire would directly impact the vertical surface of the convex surface 108c, causing some damage to the tire.

[0052] Reference Figure 3 The center beam 102 includes a crossbeam 102a and vertical beams 102b at both ends of the crossbeam 102a. The vertical beams 102b are connected to the front wheel plate 106 and the rear wheel plate 107 respectively. The perpendicular bisector E of the crossbeam 102a is in the same plane as the reference line F of the guide rail 200. A guide member 102c is provided at the perpendicular bisector E of the crossbeam 102a. The end of the guide member 102c extends into the interior of the guide rail 200 and is provided with a guide bearing 102d.

[0053] To achieve high-precision linear trajectory control during the evacuation process, the perpendicular bisector E of the crossbeam 102a and the baseline F of the guide rail 200 are precisely set in the same vertical plane. This ensures that when the vehicle evacuation platform 100 is subjected to traction, the point of force application is always on the central axis of the guide rail 200, thereby eliminating the risk of swaying caused by eccentric torque.

[0054] A guide member 102c is further installed at position E, the vertical center line of the crossbeam 102a. The end of the guide member 102c extends downward and into the internal space of the guide rail 200, and a guide bearing 102d is provided at its end. The guide bearing 102d forms a precision fit with the inner wall of the guide rail 200, converting the hard sliding friction between the platform and the guide rail into rolling friction.

[0055] Preferably, the axial length of the crossbeam 102a is limited to less than the net distance between the two sets of rotating hubs 300. By shortening the length of the crossbeam 102a, it is ensured that the travel trajectory of the first roller 102i mounted on the vertical beam 102b falls completely on the flat ground between the rotating hubs 300, which not only protects the rotating hubs 300 but also ensures flatness during removal.

[0056] Reference Figure 4 The guide bearing 102d is horizontally arranged, and the surface of the guide member 102c, located outside the guide rail 200, is provided with a traction hole 102e.

[0057] The outer ring of the guide bearing 102d forms a 5mm double-sided clearance fit with the inner side wall of the groove of the guide rail 200. When the vehicle evacuation platform 100 moves, the outer ring of the guide bearing 102d rolls into contact with the side wall of the groove of the guide rail 200, limiting the lateral offset to within ±5mm and preventing the vehicle evacuation platform 100 from shifting left or right.

[0058] The traction hole 102e serves as the mechanical connection point of the first traction cable 401, enabling direct power transmission to the vehicle evacuation platform 100.

[0059] Reference Figure 5 The vertical beam 102b is provided with a first roller 102i, the movable beam 101 is provided with a second roller 101a corresponding to the first roller 102i, and the movable beam 101 is provided with a third roller 101b in the middle. The first roller 102i, the second roller 101a and the third roller 101b are all deep groove ball bearings.

[0060] The first roller 102i, the second roller 101a, and the third roller 101b are each provided in multiple sets, and the first roller 102i, the second roller 101a, and the third roller 101b are each composed of a bearing plate and multiple deep groove ball bearings.

[0061] The vertical beam 102b and the moving beam 101 achieve efficient power transmission and load distribution through the arrangement of rollers. Multi-point rolling support transforms heavy vehicle loads into extremely low running resistance.

[0062] Because the moving beam 101 has a large span, the third roller 101b can effectively share the pressure in the middle and prevent the moving beam 101 from deforming under stress when carrying a vehicle weighing several tons.

[0063] Deep groove ball bearings can withstand significant vertical radial loads, effectively supporting the enormous impact force generated on the moving beam 101 when the vehicle enters the platform.

[0064] Reference Figure 6 The assembly 103 includes a first welding plate 103a respectively disposed on the moving beam 101 and the vertical beam 102b, a second welding plate 103b respectively disposed on the front wheel plate 106 and the rear wheel plate 107, an mounting plate 103c disposed between the first welding plate 103a and the second welding plate 103b, and a front guide roller 104 and a rear guide roller 105 respectively disposed on the mounting plate 103c.

[0065] The first welding plate 103a is precisely welded to the key stress nodes of the moving beam 101 and the vertical beam 102b, respectively, serving as the reference stress points for the entire device. Correspondingly, the second welding plate 103b is pre-placed on the sides of the front wheel plate 106 and the rear wheel plate 107, thereby facilitating the installation of the front wheel plate 106 and the rear wheel plate 107.

[0066] The three-layer plate structure design gives assembly 103 good modularity. When the front guide roller 104 and rear guide roller 105 or the front wheel plate 106 and rear wheel plate 107 need to be replaced, technicians can quickly separate them by removing the fasteners at the mounting plate 103c without performing destructive work on the main beam structure.

[0067] The assembly 103, consisting of the first welding plate 103a, the second welding plate 103b, and the mounting plate 103c, not only solves the connection problem between the large-span beam and the precision guide element, but also enhances the platform's seismic resistance during evacuation.

[0068] Reference Figure 7 The top of the central beam 102 is provided with a guard plate 102f, and the top of the guard plate 102f is provided with a traction groove 102g that is compatible with the guide member 102c. An inclined plate 102h is provided on one side of the guard plate 102f located in the traction groove 102g.

[0069] The protective plate 102f flattens and covers the recessed or protruding parts inside the central beam 102, effectively preventing workers from tripping when walking around the platform or performing debugging operations. The traction groove 102g on the top of the protective plate 102f provides ample operating space for workers. Workers can directly connect the first traction cable 401 to the traction hole 102e on the guide component via the traction groove 102g without removing any protective covers. When a vehicle reverses onto the platform or makes minor adjustments to its position, the tires may shift towards the center area. Without the tilting plate 102h, the metal edge of the vertical beam 102b or the right-angle edge of the protective plate could easily cut the tire sidewalls.

[0070] Reference Figure 8 and Figure 9 This embodiment provides a vehicle evacuation chamber, including a vehicle evacuation platform 100, a first winch 400, a column 500, and a second winch 600.

[0071] The first winch 400 is located outside the evacuation chamber and is connected to the traction hole 102e of the guide member 102c via the first traction cable 401. The column 500 is located inside the evacuation chamber and is connected to the vehicle via the fixed end G of the second traction cable 501. The second winch 600 is located between two adjacent columns 500 on the same side and is connected to the fixed end G of the second traction cable 501 via the third traction cable 601. The columns 500 are located on the side of the vehicle evacuation platform 100.

[0072] Furthermore, the first winch 400 adopts a sunken installation method, ensuring that the first traction cable 401 remains absolutely horizontal with the direction of travel of the vehicle evacuation platform 100 when under force. This not only converts 100% of the winch's pulling force into the platform's translational driving force, avoiding the vertical component force caused by cable tilting that could cause the platform to tilt up or down, but also greatly improves the pulling efficiency under heavy loads. Horizontal pulling ensures that the guide bearing 102d is evenly stressed within the guide rail, reducing additional friction and vibration caused by deviations in the resultant force direction.

[0073] When the evacuation system is not in operation or in standby mode, the first traction cable 401 can naturally sink and be stored inside the groove of the guide rail 200, keeping the evacuation chamber floor flat. When workers move between the sides of the platform or conduct vehicle testing, the guide rail groove acts as a "protective shell" for the rigging, completely eliminating the tripping risk that may be caused by the wire rope crossing the ground.

[0074] During static or dynamic vehicle testing, the column 500 serves as the main mechanical support point and is tightly connected to the vehicle's towing hook via the fixed end G of the second traction cable 501.

[0075] The column 500 is firmly anchored to the ground on the side of the vehicle evacuation platform 100, and can withstand the longitudinal and lateral vibrations generated by the vehicle during simulated operation. The second traction cable 501 provides the necessary preload to the vehicle, ensuring the stability of the vehicle's center of gravity during the experiment and preventing experimental data deviations or equipment damage due to accidental displacement.

[0076] The second winch 600 is cleverly positioned between adjacent columns 500 on the same side, a layout that does not occupy additional longitudinal space. When the vehicle completes the test and is ready to enter the evacuation procedure, the second winch 600 is activated, pulling laterally on the fixed end G of the second traction cable 501 via the third traction cable 601. The force of the third traction cable 601 is perpendicular to the evacuation direction. It can quickly pull the second traction cable 501, which was originally in the vehicle's travel path, to the two sides of the vehicle evacuation platform 100. This eliminates the risk of the vehicle's wheels running over the rope or the rope getting caught under the truck during high-speed evacuation.

[0077] This embodiment provides a vehicle evacuation method, including the following steps: When the vehicle needs to be evacuated, the locking state of the second traction cable 501 between the rear end of the vehicle and the column 500 is released, and the second winch 600 is started. The released second traction cable 501 is pulled towards the side column 500 through the third traction cable 601 to avoid the vehicle evacuation path.

[0078] Start the first winch 400, and use the first traction cable 401 to pull the vehicle away from the platform 100 and move it down the guide rail 200. The vehicle tires are moved to the front wheel plate 106 and the rear wheel plate 107 by the front guide roller 104 and the rear guide roller 105, and the vehicle is supported in the groove 108.

[0079] Once the vehicle is fully positioned on the vehicle evacuation platform 100, the locking of the second traction cable 501 between the front of the vehicle and the column 500 is released.

[0080] The first winch 400 is restarted, and the vehicle evacuation platform 100 carrying the vehicle is pulled away from the test position along the guide rail 200 by the first traction cable 401.

[0081] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
