Description

Technical Field

[0001] This utility model relates to the technical field of special vehicle maintenance equipment, and in particular to an intelligent and precise positioning platform for special vehicles. Background Technology

[0002] Traditional intelligent precision positioning platforms for special vehicles are indispensable equipment in the maintenance process, undertaking the key functions of vehicle transport and positioning. However, they have revealed numerous problems in actual use. For example, the electrical control circuitry of older models of these platforms is severely aged, and mechanical moving parts such as the transmission mechanism and gearbox show significant wear, leading to a decline in equipment performance. Simultaneously, their load-bearing capacity is insufficient to meet the transport requirements of heavy equipment. Furthermore, traditional platform designs lack drainage systems, making it easy for water to accumulate under the rotating platform. Since the motor is installed under the platform, it is highly susceptible to electrical leakage accidents, posing a serious safety hazard. Manually connecting the guide rails has a large margin of error; when there is a large track drop, the flatbed cart is prone to deviating from the track. Once a problem occurs, rework is required, wasting manpower and resources and significantly increasing maintenance costs and time. These problems severely restrict the improvement of maintenance efficiency and adversely affect the quality and safety of equipment repair.

[0003] To address the aforementioned issues, developing a new intelligent and precise positioning platform has become an urgent priority. This platform must possess high load-bearing capacity, precise positioning capabilities, and intelligent operation features to reduce vehicle transport time, increase maintenance depth, and overcome existing maintenance bottlenecks. By introducing advanced intelligent control systems, sewage and drainage systems, and efficient power systems, the shortcomings of traditional platforms can be significantly improved, thereby providing more reliable technical support for the maintenance of wheeled armored vehicles and other special vehicles. This is not only a key measure to enhance maintenance support capabilities but also an important direction for promoting technological progress in the field of equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent and precise positioning platform for special vehicles to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smart precision positioning platform for special vehicles includes a support system, a power system, a top turntable assembly, a sewage and drainage system, an electronic control system, and an emergency stop mechanism. The support system consists of a support platform and a support frame, with the support frame positioned at the central opening of the support platform to bear the weight of the entire rotating system and ensuring the platform's stability under high load conditions through its rigid structural design. Furthermore, the support frame and the turntable are rotatably connected via arc-shaped slide rails and arc-shaped guide rails, ensuring the smoothness and precision of the rotational motion.

[0007] Furthermore, the power system includes a servo motor and a transmission assembly. The servo motor has a rated power of 8.5KW, which increases its load capacity to over 10T compared to a traditional 7.5KW motor, thus meeting higher load-bearing requirements. The transmission assembly is connected to the rotating system via a reduction gear, the transmission ratio of which is optimized for precise control of the rotational speed. Specifically, the gear meshing clearance in the transmission assembly is precisely controlled to within 0.02mm to reduce vibration and noise during operation and improve system stability.

[0008] Furthermore, the top turntable assembly is mounted on the support platform and includes a rotating disk and a travel guide rail. The rotating disk is rotatably connected to the top of the support frame via an arc-shaped slide rail and an arc-shaped guide rail, ensuring uniform distribution of friction during rotation and reducing mechanical wear. The rotating disk surface is provided with a travel guide rail, which is 200mm wide and has a height difference controlled within ±0.5mm to ensure the stability and positioning accuracy of the vehicle when moving along the guide rail. In particular, the surface of the travel guide rail is hardened to a hardness of HRC50 or higher to extend its service life and reduce maintenance frequency.

[0009] Furthermore, the sewage drainage system includes a sewage ditch and a drainage channel, wherein the sewage ditch is arranged inside the support platform and communicates with the drainage channel. The drainage channel is located below the rotating disc and is used to collect water and dust brought in during vehicle entry and exit. One end of the sewage ditch extends to the outside of the support platform, forming a drainage channel with a trapezoidal cross-section, a bottom width of 50mm, a top width of 80mm, and a depth of 60mm, to ensure that accumulated water can be drained quickly. In particular, the platform is equipped with an automatic drainage pump. When the water level sensor in the drainage channel detects that the liquid level exceeds 30mm, the drainage pump automatically starts and discharges the accumulated water to the external drainage system, thereby eliminating safety hazards caused by water accumulation.

[0010] Furthermore, the electronic control system adopts a touchscreen embedded design, supporting a self-programmable operating interface. Its core function achieves precise track alignment through encoder feedback control. The encoder resolution reaches 15 bits, corresponding to an angle resolution of 0.0055 degrees per revolution, ensuring positioning accuracy meets the requirements of vehicle transport. Specifically, the electronic control system supports three control modes: fixed angle control, arbitrary angle input control, and relative control mode. The fixed angle control mode presets four commonly used angles: 0 degrees, 90 degrees, 180 degrees, and 270 degrees, and users can directly select the target angle via the touchscreen. The arbitrary angle input control mode allows users to set the target angle via an input box, ranging from 0 to 360 degrees. The relative control mode calculates the rotation increment based on the current angle, and users can customize the rotation angle value. In addition, the electronic control system also supports manual and automatic operating modes. In manual mode, users control the rotation action via buttons, while in automatic mode, the system automatically completes the rotation task according to a preset program.

[0011] Furthermore, the emergency stop setting includes an emergency stop button and a safety circuit. The emergency stop button is located in a prominent position on the operation panel. Pressing it immediately cuts off the power to the servo motor and activates the braking device, ensuring that the equipment stops quickly in an emergency. In particular, the safety circuit adopts a dual-redundancy design, with the main circuit and the backup circuit simultaneously monitoring the equipment's operating status. When the main circuit fails, the backup circuit automatically takes over, further enhancing the system's safety.

[0012] The working principle of this utility model is as follows: S1, an instruction is issued through the touch screen control interface, and the electronic control system starts the servo motor after receiving the instruction; S2, the servo motor drives the transmission component, which drives the rotating system to rotate through the reduction device; S3, the rotating system finally drives the top turntable assembly to rotate, and the travel guide rail on the turntable ensures that the vehicle can move smoothly; S4, the sewage drainage system monitors the water accumulation in real time, and when the water level exceeds the preset threshold, the automatic drainage pump starts to discharge the accumulated water to the external drainage system.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] First, by optimizing the design of the motor power and transmission components of the power system, the platform's load-bearing capacity and operating efficiency have been significantly improved, reducing the vehicle transfer time from 125 minutes / unit to 30 minutes / unit. Second, by introducing a 15-bit resolution encoder and an intelligent electronic control system, high-precision positioning during vehicle transfer has been achieved, with errors controlled within ±0.01 degrees. Third, by setting up a sewage and drainage system and an emergency stop button, the safety hazards of water accumulation, leakage, and emergencies have been effectively eliminated. Finally, the user-friendly touchscreen interface and multiple control modes have reduced the difficulty of operation and improved the user experience.

[0015] In particular, the structural design and optimized control system of this invention make it widely applicable in the maintenance and production of special vehicles such as wheeled armored vehicles and armed police riot control armored vehicles. By shortening vehicle transport time, improving positioning accuracy, and enhancing safety, this invention not only improves the quality and efficiency of equipment repair but also reduces maintenance costs, thus possessing significant military and industrial application value.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0025] like Figures 1 to 3 As shown, this utility model discloses an intelligent precision positioning platform for special vehicles, which mainly includes a support system, a power system, a top turntable assembly, a sewage and drainage system, an electrical control system, and an emergency stop mechanism. These components work together to ensure that the platform has efficient transport capabilities and stable operating performance during actual use. The support system consists of a support platform 8 and a support frame 6. The support platform 8 is the basic structure of the entire platform, and its surface is hardened to enhance wear resistance. The support frame 6 is arranged at the central opening. The support frame 6 is made of high-strength steel, and its rigidity design has been optimized through mechanical analysis to ensure that it can withstand loads of up to 10 tons or more. The support frame 6 is rotatably connected to the top turntable assembly 3 through arc-shaped slide rails and arc-shaped guide rails. The surfaces of the arc-shaped slide rails and arc-shaped guide rails are coated with a low-friction coefficient lubricating material, thereby reducing friction during rotation and improving the smoothness of movement.

[0026] The power system 7 includes a servo motor and a transmission assembly. The servo motor is an 8.5KW rated power model, which, compared to a traditional 7.5KW motor, offers greater output torque and faster response, meeting the operational demands under higher load conditions. The transmission assembly is connected to the rotating system 4 via a reduction gear 5. The reduction gear 5 employs a planetary gear structure with a precisely calculated transmission ratio, maximizing torque transmission efficiency while ensuring controllable rotational speed. The gear meshing clearance in the transmission assembly is controlled within 0.02mm, achieved through precision machining, thereby reducing vibration and noise during operation and extending the equipment's lifespan. Furthermore, the servo motor incorporates a 15-bit resolution encoder with an angle resolution of 0.0055 degrees per revolution, enabling precise control of the rotational angle through encoder feedback.

[0027] The top turntable assembly 3 is mounted on the support platform 8. Its core component is the rotating disc, whose surface is equipped with a travel guide rail. The width of the travel guide rail is 200mm, and the height difference is strictly controlled within ±0.5mm to ensure the stability of the vehicle when moving along the guide rail. The surface of the travel guide rail undergoes a heat treatment process, achieving a hardness of HRC50 or higher, significantly improving wear resistance and reducing maintenance frequency. The rotating disc is rotatably connected to the top of the support frame 6 via arc-shaped slide rails and arc-shaped guide rails. The design of the arc-shaped slide rails and arc-shaped guide rails ensures that the rotating disc maintains a uniformly distributed friction force under stress, thereby effectively reducing mechanical wear. To further enhance the stability of the rotating disc, multiple sets of ball bearings are installed inside the arc-shaped slide rails. The ball bearings have a diameter of 10mm and can withstand radial and axial loads, ensuring smooth rotational movement.

[0028] The sewage drainage system consists of a sewage ditch 1 and a drainage channel 2. The drainage channel 2, located below the rotating platform, collects water and dust brought in by vehicles during entry and exit. The drainage channel 2 has a rectangular cross-section, 200mm wide and 50mm deep, capable of accommodating large volumes of water or debris. The sewage ditch 1, located inside the support platform 8 and connected to the drainage channel 2, has a trapezoidal cross-section, 50mm wide at the bottom, 80mm wide at the top, and 60mm deep. This design ensures rapid drainage, preventing safety hazards caused by water accumulation. One end of the sewage ditch 1 extends to the outside of the support platform 8, forming a drainage channel. A filter screen with a 5mm aperture is installed at the drainage channel outlet to intercept larger debris and prevent blockage of the drainage pipe. Furthermore, the platform is equipped with an automatic drainage pump. When the water level sensor in the drainage channel 2 detects a liquid level exceeding 30mm, the automatic drainage pump activates and discharges the water to the external drainage system. The water level sensor uses a float-type design with adjustable sensitivity to adapt to different environmental conditions.

[0029] The electrical control system employs an embedded touchscreen design, with the touchscreen prominently positioned on the control panel and supporting a customizable operating interface. The touchscreen interface offers three control modes: fixed angle control, arbitrary angle input control, and relative control. The fixed angle control mode presets four commonly used angles: 0 degrees, 90 degrees, 180 degrees, and 270 degrees. Users can directly select the target angle via the touchscreen; upon receiving the command, the system activates the servo motor and drives the rotating disk to the designated position. The arbitrary angle input control mode allows users to set the target angle via an input box, ranging from 0 to 360 degrees. The system calculates the rotation increment based on the input value and executes the corresponding action. The relative control mode calculates the rotation increment based on the current angle. Users can customize the rotation angle value; for example, setting the rotation increment to 45 degrees will cause the rotating disk to rotate 45 degrees clockwise or counterclockwise from its current position. The electronic control system also supports both manual and automatic working modes. In manual mode, the user controls the rotation by pressing a button, and the rotary disk rotates by a preset increment each time the button is pressed. In automatic mode, the system automatically completes the rotation task according to a preset program, such as rotating in the order of 0 degrees, 90 degrees, 180 degrees, and 270 degrees, with a dwell time of 30 seconds at each angle.

[0030] The emergency stop system includes an emergency stop button and a safety circuit. The emergency stop button is prominently located on the control panel; pressing it immediately cuts off the servo motor power and activates the braking device. The braking device uses an electromagnetic brake to achieve rapid stopping, with a braking response time of less than 0.5 seconds. The safety circuit employs a dual-redundancy design, with both the main and backup circuits simultaneously monitoring the equipment's operating status. If the main circuit fails, the backup circuit automatically takes over, further enhancing system safety. In addition, the electrical control system is equipped with overload protection; when the servo motor load exceeds the rated value, it automatically cuts off the power supply to prevent equipment damage due to overload.

[0031] The working principle of this utility model is as follows: First, a command is issued through the touch screen control interface. After receiving the command, the electronic control system starts the servo motor. The servo motor drives the transmission component and drives the rotating system 4 to rotate through the reduction device. The rotating system 4 ultimately drives the top turntable assembly 3 to rotate. The travel guide rail on the turntable ensures that the vehicle can move smoothly. At the same time, the sewage drainage system monitors the water accumulation in real time. When the water level exceeds the preset threshold, the automatic drainage pump starts to discharge the accumulated water to the external drainage system. In practical applications, this utility model's intelligent precision positioning platform for special vehicles is mainly used in the maintenance and production of special vehicles such as wheeled armored vehicles and armed police series riot control armored vehicles. For example, during the maintenance of wheeled armored vehicles, after the maintenance personnel drive the vehicle into the turntable, they set the target angle to 90 degrees through the touch screen. After receiving the command, the system starts the servo motor and drives the turntable to rotate to the 90-degree position. Then, the maintenance personnel can perform subsequent maintenance operations on the vehicle. Since the positioning accuracy of this utility model is as high as ±0.01 degrees, it can significantly improve the vehicle transfer efficiency and shorten the maintenance cycle.

[0032] In summary, this utility model achieves high load-bearing capacity, high-precision positioning, and intelligent operation through optimized structural design and control system. It is widely used in the field of special vehicle maintenance and production and has significant military and industrial application value.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
