Description

Technical Field

[0001] This invention relates to material handling equipment technology, specifically to a liftable special vehicle handling platform. Background Technology

[0002] With the widespread application of special vehicles in emergency rescue, municipal construction, and other fields, the demand for efficient and safe handling in warehousing, transshipment, and specific operational scenarios is becoming increasingly prominent. Liftable handling platforms are key equipment for enabling the vertical transfer and short-distance movement of such heavy, high-center-of-gravity vehicles.

[0003] Chinese invention patent CN115070317A discloses a special vehicle active wheel positioning device. This device is designed based on the geometric shape of the special vehicle active wheel through pneumatic principle analysis. It uses pneumatic components to achieve precise positioning of the special vehicle active wheel. When used in conjunction with a handling robot and a welding robot, it can further realize fully automated loading, unloading and welding operations of the special vehicle active wheel, solving problems such as low automation and high labor intensity of manual handling in the welding operation of the special vehicle active wheel.

[0004] Existing equipment, when in use, cannot adapt to the tire size and parking position deviation of different vehicle models with rigid blocks, requiring repeated manual adjustments, which is inefficient and the locking effect is unstable. Furthermore, the preload is difficult to quantify and control. If it is too loose, it may cause the vehicle to shift, while if it is too tight, it may damage the vehicle suspension or body. Moreover, it is prone to loosening under long-term or vibration conditions, posing a safety hazard. At the same time, there is a risk of vehicle tipping over due to tilting or uneven ground during transportation, and stress concentration may occur when the vehicle shifts slightly, which may damage vehicle components. Therefore, a liftable special vehicle transportation platform was developed. Summary of the Invention

[0005] The purpose of this invention is to provide a liftable special vehicle handling platform to overcome the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liftable special vehicle handling platform, comprising a lifting platform body for carrying special vehicles;

[0007] A vehicle axle locking assembly is mounted around the upper part of the lifting platform body to adaptively abut against and lock the wheels of the special vehicle.

[0008] A protective component, which is assembled at the upper end of the main body of the lifting platform, is used to limit the lateral displacement of the vehicle during transportation.

[0009] The axle locking assembly includes a base plate that engages with the main body of the lifting platform. Two support blocks are symmetrically fixed at the ends of the base plate, and a fixing plate is fixed at the ends of the support blocks.

[0010] The fixed plate has a movable plate rotatably mounted at one end, the movable plate has a positioning rod fixedly mounted at one end, and the positioning rod has a positioning block rotatably mounted at one end.

[0011] A sliding rod is fixedly provided at the end of the fixed plate, a locking block is slidably provided on the outer surface of the sliding rod, and a locking plate is fixedly provided at the end of the locking block;

[0012] The inner wall of the locking plate is provided with a locking groove, the inner wall of the locking groove is inclined, and the inner wall of the locking groove is rotatably connected to the outer surface of the positioning block.

[0013] The outer surface of the positioning rod is rotatably provided with a movable block, the end of the movable block is rotatably provided with a support plate, the lower end of the support plate is fixedly provided with a hydraulic rod, and the lower end of the hydraulic rod is connected to the upper end of the base plate.

[0014] As a further optimization of the present invention, a rotating block is rotatably provided at the end of the fixed plate, and an elastic element is fixedly provided at the end of the rotating block, with the end of the elastic element connected to the outer surface of the movable plate.

[0015] As a further optimization of the present invention, an adjusting block is fixedly provided at the end of the support plate, a guide block is fixedly provided at the end of the adjusting block, and a guide rod is slidably provided on the inner wall of the guide block.

[0016] As a further optimization of the present invention, the upper end of the base plate is provided with a guide groove corresponding to the guide rod, and the inner wall of the guide groove is slidably connected to the outer surface of the guide rod.

[0017] As a further optimization of the present invention, the protective component includes a protective plate that is snapped into the main body of the lifting platform, and a turntable is symmetrically rotatably provided at the end of the protective plate.

[0018] As a further optimization of the present invention, a swing rod one is rotatably provided at the end of the turntable near the edge, and a swing rod two is rotatably provided at the end of the turntable and on one side of the swing rod one, and the swing rod one and the swing rod two are staggered.

[0019] As a further optimization of the present invention, the ends of the first swing rod and the second swing rod are rotatably provided with limiting plates.

[0020] As a further optimization of the present invention, a protective rod is rotatably provided at the end of the protective plate, and the end of the protective rod is rotatably connected to the end of the limiting plate.

[0023] Compared with the prior art, the lifting special vehicle handling platform provided by the present invention has the following beneficial effects:

[0024] The axle locking assembly automatically adapts to tire size, tread profile, and parking position deviations of vehicles of different specifications, ensuring consistency in the locking process and precise application of optimal locking force. This avoids the tedious operation of manual adjustment, significantly improves work efficiency, and effectively prevents damage to the vehicle suspension or body due to excessive preload, as well as the risk of vehicle displacement caused by insufficient preload.

[0025] The protective components, through a multi-link linkage structure, can adaptively adjust the unfolding range of the limiting plate according to the vehicle width, so that the moving blocks on the pallet fit tightly against the side of the vehicle, forming multi-dimensional lateral support. This effectively limits the lateral displacement of the vehicle during transportation caused by road bumps, centrifugal force during steering, or platform tilt. Combined with the axle locking components, the double protection further reduces the risk of vehicle tipping over, avoids stress concentration that could damage vehicle components, and improves the safety and reliability of the overall transportation process.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Example: Please refer to Figure 1 - Figure 3 A lifting special vehicle handling platform includes a lifting platform body 1 for carrying special vehicles.

[0040] In this solution, the main body 1 of the lifting platform is equipped with components such as hydraulic cylinders that have telescopic functions, which are used to lift the special vehicles it carries to a suitable height so that they can meet the needs of different scenarios.

[0041] The side of the main body 1 of the lifting platform is equipped with a drive device to move the main body 1 of the lifting platform as a whole, so as to realize the short-distance transfer of special vehicles. At the same time, a hoisting device is set on the top of the main body 1 of the lifting platform to transport the vehicle body onto the platform. The hoisting device has an adjustable structure, which can be adaptively adjusted according to the external size and center of gravity of the special vehicle to ensure the stability and balance of the vehicle during the hoisting process.

[0042] Furthermore, the axle locking assembly 2 is assembled around the upper part of the lifting platform body 1 to adaptively abut against and lock the wheels of the special vehicle; wherein, the axle locking assembly 2 includes a base plate 21 that is snapped into the lifting platform body 1, and two support blocks 211 are symmetrically fixedly arranged at the ends of the base plate 21, and a fixing plate 22 is fixedly arranged at the ends of the support blocks 211.

[0043] In this embodiment, the bottom plate 21 is provided with bolts and other fixing components at its end. The bottom plate 21 is locked to the upper end of the lifting platform body 1 by bolts. At the same time, the symmetrically arranged support blocks 211 support and limit the fixing plate 22 to keep it in a stable installation state.

[0044] Furthermore, a movable plate 24 is rotatably provided at the end of the fixed plate 22, a positioning rod 241 is fixedly provided at the end of the movable plate 24, and a positioning block 242 is rotatably provided at the end of the positioning rod 241.

[0045] Specifically, when the positioning rod 241 is subjected to force, it synchronously drives the movable plate 24 to rotate around the connection with the fixed plate 22, and at the same time drives the positioning block 242, which is rotatably set on the positioning rod 241, to move.

[0046] Furthermore, a slide rod 25 is fixedly provided at the end of the fixed plate 22, a locking block 251 is slidably provided on the outer surface of the slide rod 25, and a locking plate 26 is fixedly provided at the end of the locking block 251.

[0047] Specifically, the locking block 251 is limited by the slide bar 25, so that the locking block 251 can move up and down on the outer surface of the slide bar 25, thereby keeping the locking plate 26 in a stable state when it moves, and avoiding the impact of shaking on the locking accuracy.

[0048] Furthermore, the inner wall of the locking plate 26 is provided with a locking groove 261, the inner wall of the locking groove 261 is inclined, and the inner wall of the locking groove 261 is rotatably connected to the outer surface of the positioning block 242.

[0049] Specifically, when the positioning block 242 moves, its outer surface will slide along the inner wall of the inclined locking groove 261. Due to the inclined angle design of the inner wall of the locking groove 261, the movement of the positioning block 242 will generate a lateral thrust on the locking plate 26, thereby driving the locking block 251 to slide along the outer surface of the slide bar 25, so that the locking plate 26 can move closer to or further away from the vehicle tire, realizing adaptive contact with tires of different sizes.

[0050] At the same time, when the positioning block 242 moves to the appropriate position in the locking groove 261, the locking plate 26 can stably abut against the side of the tire, initially restricting the lateral displacement of the tire.

[0051] Furthermore, a movable block 27 is rotatably provided on the outer surface of the positioning rod 241, and a support plate 271 is rotatably provided at the end of the movable block 27. A hydraulic rod 272 is fixedly provided at the lower end of the support plate 271, and the lower end of the hydraulic rod 272 is connected to the upper end of the base plate 21.

[0052] Specifically, when the hydraulic rod 272 is activated, it drives the support plate 271 fixed at its end to move downward, thereby synchronously pulling the movable block 27 to move. The inner wall of the movable block 27 is rotatably connected to the outer surface of the positioning rod 241, thereby driving the positioning rod 241 to move towards the middle position.

[0053] When the positioning rod 241 moves towards the center, it drives the movable plate 24 to rotate around the fixed plate 22, thereby causing the positioning block 242 to slide within the locking groove 261, pushing the locking plate 26 towards the tire and clamping it in place. The thrust of the hydraulic rod 272 can be precisely controlled by an external control device, thereby achieving quantitative adjustment of the locking preload and avoiding excessive looseness or tightness. When there are differences in vehicle tire size or slight deviations in parking position, the sliding stroke of the positioning block 242 within the inclined locking groove 261 will automatically adjust, allowing the locking plate 26 to adaptively conform to the sidewalls of tires of different sizes, eliminating the need for repeated manual adjustments, thus improving operational efficiency and the stability of the locking effect.

[0054] Furthermore, a rotating block 23 is rotatably provided at the end of the fixed plate 22, and an elastic element 231 is fixedly provided at the end of the rotating block 23. The end of the elastic element 231 is connected to the outer surface of the movable plate 24.

[0055] Specifically, the elastic element 231, such as a spring, is used to limit the movable plate 24. After the movable plate 24 is no longer under force, the force of the elastic element 231, in conjunction with the elastic force, stretches the movable plate 24 to its initial position for easy reuse. When the hydraulic rod 272 drives the movable plate 24 to rotate, the elastic element 231 is correspondingly stretched or compressed, storing elastic potential energy. When the driving force of the hydraulic rod 272 is removed, the elastic element 231 releases its potential energy, causing the movable plate 24 to reset, thereby returning the positioning rod 241, positioning block 242, and locking plate 26 to their initial state, preparing for the next step of locking the vehicle.

[0056] Furthermore, an adjusting block 28 is fixedly provided at the end of the support plate 271, a guide block 281 is fixedly provided at the end of the adjusting block 28, and a guide rod 282 is slidably provided on the inner wall of the guide block 281.

[0057] Specifically, the adjusting block 28 is a telescopic component such as an electric telescopic rod, and is connected to an external control device. The adjusting block 28 drives the guide block 281 to move, making it suitable for tires of different widths. When the guide block 281 moves, its inner wall will slide along the outer surface of the guide rod 282. The guide block 281 precisely limits the movement trajectory of the guide rod 282, ensuring that when the adjusting block 28 moves with the support plate 271, it avoids affecting the locking accuracy of the axle locking assembly 2 for the wheels due to deviation.

[0058] Furthermore, the upper end of the base plate 21 is provided with a guide groove 212 corresponding to the guide rod 282, and the inner wall of the guide groove 212 is slidably connected to the outer surface of the guide rod 282.

[0059] Specifically, the guide rod 282 is constrained by the guide groove 212, so that the guide rod 282 is in a stable state when it moves, and avoids deviation. When the support plate 271 moves under the drive of the hydraulic rod 272, the guide rod 282 will slide in the guide groove 212, which further enhances the stability of the support plate 271 during movement, ensuring that the components of the axle locking assembly 2 can work together precisely and improve the locking effect on the wheels.

[0060] Furthermore, the protective component 3, which is assembled on the upper end of the lifting platform body 1, is used to limit the lateral displacement of the vehicle during the transportation process; the protective component 3 includes a protective plate 31 that is snapped into the lifting platform body 1, and a turntable 32 is symmetrically rotatably provided at the end of the protective plate 31.

[0061] In this embodiment, the end of the protective plate 31 is provided with bolts or other fixing components to lock the protective plate 31 in a suitable position. At the same time, the end of the turntable 32 is provided with a motor or other power output device and is connected to an external control device. When the motor starts, it synchronously drives the turntable 32 fixedly set at its output end to rotate.

[0062] Furthermore, a swing rod 33 is rotatably provided at the end of the turntable 32 near the edge, and a swing rod 34 is rotatably provided at the end of the turntable 32 and on one side of the swing rod 33, with the swing rod 33 and the swing rod 34 being staggered.

[0063] Specifically, when the turntable 32 rotates, one end of the swing rod 33 and the swing rod 34 on its edge will move in a circle with the turntable 32. Since the two are staggered, the motion trajectory and phase difference will drive the limiting plate 35 connected to the other end to translate.

[0064] When turntable 32 rotates clockwise, swing lever 33 may push limiting plate 35 toward the direction of the vehicle, while swing lever 34 assists limiting plate 35 to remain stable at different positions on its trajectory and avoids shaking.

[0065] Furthermore, a limiting plate 35 is rotatably provided at the ends of the swing rod 33 and the swing rod 34. A protective rod 36 is rotatably provided at the end of the protective plate 31, and the end of the protective rod 36 is rotatably connected to the end of the limiting plate 35.

[0066] Specifically, when the limiting plate 35 moves under the drive of the first swing rod 33 and the second swing rod 34, its end will drive the protective rod 36 to rotate around the end of the protective plate 31.

[0067] The movement trajectory of the limiting plate 35 is constrained by the protective rod 36, so that it can only move in a straight line or near-straight line within a preset plane, ensuring that the limiting plate 35 can accurately abut against the side of the vehicle.

[0068] As the limiting plate 35 moves toward the vehicle, the protective bar 36 gradually becomes more vertical from its initial tilted state, providing lateral support to the limiting plate 35 and preventing it from tilting or falling over when it comes into contact with the vehicle, thus enhancing the overall structural stability of the protective assembly 3.

[0069] Furthermore, a push rod 37 is rotatably provided on the outer surface of the protective rod 36, and a movable rod 38 is rotatably provided at the end of the push rod 37. The outer surface of the movable rod 38 is rotatably connected to the end of the limiting plate 35.

[0070] Specifically, during the rotation of the protective rod 36, the push rod 37 on its outer surface will change angle accordingly, thereby pushing the moving rod 38 to rotate around the end of the limiting plate 35.

[0071] This allows the moving rod 38 to adjust its position synchronously as the limiting plate 35 approaches the vehicle. Together with the first swing rod 33, the second swing rod 34, and the protective rod 36, it forms a multi-link coordinated motion mechanism, which improves the smoothness and accuracy of the movement of the limiting plate 35 and ensures that it can apply lateral restraint force to the vehicle evenly.

[0072] Furthermore, a support plate 39 is fixedly provided at the end of the movable rod 38, and a movable block 391 is slidably provided at the end of the support plate 39.

[0073] Specifically, the end of the movable block 391 is equipped with a telescopic component such as an electric telescopic rod. The movable block 391 is moved by the electric telescopic rod, thereby providing auxiliary support for the bottom of the vehicle and preventing the vehicle from shaking due to the shift of the center of gravity during lifting or transportation.

[0074] When the limiting plate 35 abuts against the side of the vehicle, the movable block 391 can slide on the support plate 39 to a suitable support point at the bottom of the vehicle. The extension and retraction of the electric telescopic rod achieves the tightening of the bottom of the vehicle, forming a double limit from the side and the bottom. The support plate 39 provides a stable sliding track for the movable block 391, ensuring that its movement process is precise and controllable.

[0075] The control device can be a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0076] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
