Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a liftable high-speed rolling bed with synchronous belt drive. Background Technology

[0002] In the automotive manufacturing industry, the conveying speed of existing production line lifting conveyor rollers is insufficient to meet the ever-increasing production demands. Their slow rolling speed results in long material turnaround times at individual workstations, severely restricting overall production efficiency. This not only extends the automotive production cycle but also increases production costs and reduces the company's market competitiveness.

[0003] Conveyor rollers in automotive manufacturing production lines are key equipment for material handling. Early rollers only had simple horizontal conveying functions, relying on ordinary motors and chain drives, resulting in limited conveying speeds. With technological advancements, some rollers added lifting functions, but still have many shortcomings in power transmission and overall performance. Some similar rollers use hydraulic systems for lifting, which can provide greater lifting force, but suffer from slow response speed, complex equipment maintenance, and easy hydraulic oil leakage. In terms of horizontal conveying, chain drives are prone to wear, generate high noise, and have high power losses, making it difficult to achieve high-speed and stable conveying. Even some improved rollers have attempted to optimize the transmission structure, but they still cannot fundamentally solve the problems of speed and efficiency, and cannot meet the demands of modern automotive manufacturing production lines for highly efficient conveying equipment. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a synchronous belt-driven, liftable high-speed roller bed. Employing an innovative structural design and power transmission method, it creates a roller bed capable of high-speed horizontal conveying and efficient lifting, effectively solving the problem of slow speed in existing conveying equipment and increasing the production capacity of automobile manufacturing lines. The specific technical solution is as follows: A high-speed rolling bed with synchronous belt drive and adjustable height, the rolling bed consists of a rolling bed base, a lifting mechanism, a skid, a safety mechanism, a guiding mechanism and a clamping mechanism; The roller bed base has a motor mounting seat in the middle and driven sprocket mounting seats on both sides. The lifting motor is mounted on the motor mounting seat, and two drive sprockets on the lifting motor are connected to the driven sprockets on both sides via synchronous belts. A crank is mounted on one side of each driven sprocket via a cam bearing, and on the other side via a crankshaft. The lifting mechanism is mounted on the roller bed base and includes a lifting frame, roller shafts, and guide plates. Multiple roller shafts are provided, each with a synchronous pulley and a corresponding synchronous belt. The lifting motor, after speed reduction and torque amplification via a reducer, drives the synchronous pulleys to rotate, and the synchronous belt drives the cranks to rotate. The skid consists of two skid plates. The system comprises a central connecting frame, which is mounted above the lifting mechanism. The safety mechanism is located at both ends of the roller bed and includes a rotating shaft, mounting base, rocker arm, telescopic rod, and bolts. The rocker arm is mounted on the mounting base via the rotating shaft, and a telescopic rod is positioned above the rocker arm, with bolts at the top of the telescopic rod. The guiding mechanism is located beside the moving sprocket mounting base and consists of a guide bracket, axle, guide rail, and guide column. The axle slides on the guide column. The clamping mechanism consists of a mounting base, rotating shaft, bracket, cylinder, transmission gear, pressure arm, and pressure block. The cylinder is mounted on the bracket and controls the rotation of the transmission gear via the rotating shaft, thereby controlling the pressure arm to clamp the pressure block. The motor mounting base is welded from high-strength steel.

[0005] Furthermore, the surface of the skid is provided with anti-slip textures or positioning grooves, which can effectively prevent the material from sliding or shifting during conveying and lifting, ensuring the safety and stability of material transportation; the skid is made of lightweight and high-strength aluminum alloy material, which reduces its own weight while ensuring load-bearing capacity, and helps to improve the operating efficiency of the roller bed.

[0006] Furthermore, the roller bed base is provided with multiple mounting holes for fixing components such as the lifting mechanism and the guide mechanism, ensuring that the installation position of each component is accurate and the connection is firm.

[0007] Furthermore, the clamping mechanism is electrically controlled.

[0008] The electrode mounting base of this invention serves as the supporting foundation for the entire equipment. Welded from high-strength steel, it possesses excellent rigidity and stability, capable of withstanding various loads during equipment operation. The lifting motor, after being reduced in speed and torque by a reducer, drives the synchronous pulley to rotate, which in turn drives the crank to rotate. The crank engages with a nut on the lifting platform to achieve vertical lifting. This design utilizes the high precision and efficiency of synchronous belt transmission to ensure smooth and rapid lifting of the platform, and allows for precise control of the lifting height. When the lifting conveyor roller is under maintenance, the rocker arm can be raised via the safety mechanism's rotating shaft to adjust the height of the telescopic rod and finely adjust the bolts, thus supporting the roller bed surface and protecting the lifting roller bed from falling, preventing personnel from contacting moving parts and avoiding accidental injury. During the lifting process, the guide mechanism provides precise guidance to ensure vertical lifting and avoids tilting and swaying. A clamping mechanism is also included; through electric control, pneumatic clamping offers advantages such as fast response and simple structure. The clamping device is driven by a cylinder to clamp the slide bar, preventing it from loosening or falling off during operation. This invention relates to a high-speed, liftable roller bed driven by a motor and equipped with a synchronous belt drive. Utilizing the high efficiency, accuracy, and low maintenance of synchronous belt drives, combined with an optimized lifting and horizontal conveying structure, the roller bed's conveying speed and lifting efficiency are improved, while reducing equipment failure rates and maintenance costs, thereby meeting the high-efficiency production requirements of automobile manufacturing lines.

A lifting motor 15 is mounted on the motor mounting seat. Two drive sprockets 12 are mounted on the lifting motor 15 and connected to the driven sprockets 18 on both sides via synchronous belts. A crank 14 is mounted on one side of each driven sprocket 18 via a cam bearing, and a crankshaft 17 is mounted on the other side. Figure 3 As shown, the lifting mechanism 2 is mounted on the roller bed base 1 and includes a lifting frame 22, roller shafts 23, and guide plates 21. Multiple roller shafts 23 are provided, each with a synchronous pulley and a corresponding synchronous belt. The lifting motor 15, after speed reduction and torque amplification via a reducer, drives the synchronous pulleys to rotate, and the synchronous belt drives the crank 14 to rotate. Figure 4 As shown, the skid 3 consists of two skid plates 31 and a connecting frame in the middle, and it is mounted above the lifting mechanism 2; Figure 5 As shown, the safety mechanism 4 is located at both ends of the rolling mill and includes a rotating shaft 45, a mounting base 44, a rocker arm 43, a telescopic rod 42, and a bolt 41. The rocker arm 43 is mounted on the mounting base 44 via the rotating shaft 45. The telescopic rod 42 is located above the rocker arm 43, and the bolt 41 is located at the top of the telescopic rod. Figure 6As shown, the guide mechanism 5 is located beside the sprocket mounting seat and consists of a guide bracket 54, axle 53, guide rail 52, and guide post 51. The axle 53 is mounted on the guide post 52 and slides. Figure 7 As shown, the clamping mechanism 6 consists of a mounting base 65, a rotating shaft 64, a bracket 67, a cylinder 66, a transmission gear 62, a pressure arm 63, and a pressure block 61. The cylinder 66 is mounted on the bracket 67, and the cylinder 66 controls the rotation of the transmission gear 62 through the rotating shaft 54, thereby controlling the pressure arm 63 to press the pressure block 61. The motor mounting base 13 is welded from high-strength steel.

[0013] The surface of the skid 3 is provided with anti-slip textures or positioning grooves.

[0014] The roller bed base is provided with multiple mounting holes for fixing components such as the lifting mechanism and the guide mechanism, ensuring that the installation position of each component is accurate and the connection is firm.

[0015] The clamping mechanism 6 is electrically controlled.

[0016] At the start of operation, the car body on the skid receives a forward transport command from the previous workstation. Upon receiving the command, the control system first starts the horizontal conveyor motor. The motor drives the rollers via a synchronous belt, and the skid begins high-speed horizontal transport under the drive of the rollers. When the skid reaches the designated position, the control system sends a signal to the lifting motor to lower it. The lifting motor starts and lowers the lifting platform via a synchronous belt and lead screw. After lowering, the car body is positioned at the workstation and the work is completed. Then, the lifting motor starts again, raising the lifting platform via a synchronous belt and lead screw. After raising, the horizontal conveyor motor starts again, transporting the skid to the next workstation. Throughout the process, safety mechanisms and sensors monitor the operating status of the roller bed in real time. For example, limit switches monitor the position of the lifting platform, and sensors detect the clamping status of the skid. If any abnormality is detected, the safety mechanisms immediately activate, stopping the roller bed's operation to ensure the safety of personnel and equipment.

[0017] Field verification showed that, compared with traditional conveyor roller beds, this new roller bed increases horizontal conveying speed by 50% and lifting efficiency by 30%. The application of synchronous belt drive significantly improves power transmission efficiency, reduces energy loss, and also reduces equipment noise and wear. The optimized design of each component enhances the stability and reliability of the equipment, reduces the failure rate, and lowers maintenance costs. The precision control system based on sensor feedback improves equipment safety, effectively preventing accidents caused by operational errors or equipment malfunctions. It effectively meets the high-efficiency production needs of automobile manufacturing lines, improving the economic benefits and market competitiveness of enterprises.
