Description

[0002] In high-speed railway construction, box girder mesh structures are increasingly widely used as a key reinforcement material for bridge deck pavement. The box girder mesh, formed by the precise welding of multiple transverse and longitudinal reinforcement bars, creates a robust grid structure that significantly improves the overall strength of the bridge deck and enhances its durability to withstand the complex mechanical environment brought about by high-speed train operation. In traditional box girder mesh designs, the transverse and longitudinal reinforcement bars are bent at the ends to form a U-shaped structure, which helps to enhance the overall stability and deformation resistance of the mesh.

[0003] However, despite the excellent structural performance of the box girder mesh, the feeding of transverse reinforcement during its production still relies on traditional manual handling. This method is not only inefficient and unable to meet the needs of large-scale railway construction, but also prone to worker fatigue and potential safety accidents due to the weight and volume of the transverse reinforcement. Furthermore, the precision of manual operation is difficult to guarantee, which may lead to unstable welding quality of the mesh, thus affecting the overall construction quality and service life of the bridge deck.

[0038] like Figures 1 to 4 As shown, this embodiment provides a feeding mechanism that can accurately deliver steel bars of various lengths from one position to another. The feeding mechanism includes a base 1 and a feeding unit 2. The feeding unit 2 includes a fixed beam 21, a movable beam 22, a drive assembly 23, and a transmission assembly 24. The fixed beam 21 is fixedly mounted on the base 1. Both the fixed beam 21 and the movable beam 22 are provided with multiple storage troughs 29 arranged along the feeding direction. The storage troughs 29 are used to hold the steel bars 3 to be fed. The drive assembly 23 can drive the movable beam 22 to move relative to the fixed beam 21 through the transmission assembly 24, so that the movable beam 22 conveys the steel bars 3 to be fed from the fixed beam 21 along the feeding direction. The fixed beam 21 can be fixedly installed on the base 1 by support columns. Multiple fixed beams 21 can be provided to improve the stability of supporting the steel bars 3 to be fed. The multiple storage troughs 29 can be arranged at equal intervals to facilitate conveying at a constant cycle time. The storage trough 29 can be a trough opened on the fixed beam 21 and the movable beam 22, or it can be a block structure with a trough. The shape of the trough can be an inverted triangle.

[0039] The reinforcing bars 3 to be fed are placed in the storage trough 29 of the fixed beam 21. The drive assembly 23 drives the movable beam 22 to move relative to the fixed beam 21 through the transmission assembly 24, so that the movable beam 22 transports the reinforcing bars 3 to be fed from one storage trough 29 to another storage trough 29 along the feeding direction. Through the automated feeding mechanism, the need for manual handling is reduced, the efficiency of reinforcing bar feeding is significantly improved, and the needs of large-scale railway construction can be better met. The feeding mechanism completes the handling of reinforcing bars in a mechanized manner, reducing the physical labor of workers and reducing the fatigue of workers during the handling process, thereby reducing safety accidents caused by fatigue. The automated feeding mechanism can accurately control the position and conveying process of the reinforcing bars, avoid errors in manual operation, ensure the stability of the mesh welding quality, and thus improve the overall construction quality and service life. It reduces the direct participation of humans in the handling process, reduces the risk of safety accidents caused by improper operation or fatigue, and improves the safety of the working environment. The mechanized feeding process can ensure the consistency of each feeding, avoid deviations that may occur in manual operation, and ensure the uniformity and stability of the mesh welding.

[0040] Optionally, the transmission assembly 24 includes a first main shaft 241, a first crank 242, and a first crankshaft 243. One end of the first crank 242 is connected to the first main shaft 241, and the other end of the first crank 242 is connected to the first crankshaft 243. The movable beam 22 is provided with a first seat plate 221, and the first crankshaft 243 is connected to the first seat plate 221 through a first connecting arm 244. Since the first main shaft 241 and the first crankshaft 243 are arranged in parallel and connected to different positions of the first crank 242, when the first main shaft 241 rotates, the first crankshaft 243 will perform circular motion, thereby driving the movable beam 22 to perform circular motion. The transmission assembly 24 adopts a mechanical crankshaft structure, which is stable in operation and noiseless. Two transmission assemblies 24 can be provided, and the two transmission assemblies 24 are symmetrically arranged on both sides of the drive assembly 23. One end of the first main shaft 241 is rotatably connected to a bearing seat on the base 1, and the other end is connected to the drive assembly 23. Through the transmission structure of the first main shaft 241, the first crank 242, and the first crankshaft 243, the rotational motion of the drive assembly 23 can be converted into the reciprocating motion of the movable beam 22, ensuring that the motion trajectory of the movable beam 22 during the feeding process is precisely controllable, thereby improving the accuracy and stability of the feeding. The structural design of the crank and crankshaft can efficiently transmit the power of the drive assembly 23 to the movable beam 22, realizing fast and smooth feeding action, further improving the overall efficiency of the feeding mechanism. The mechanical transmission method of the crank and crankshaft simplifies the overall structure of the feeding mechanism, reduces the complexity of manufacturing and maintenance, and improves the reliability and durability of the mechanism. The first crankshaft 243 is connected to the first seat plate 221 of the movable beam 22 through the first connecting arm 244, ensuring the stability of the movable beam 22 during the movement, avoiding feeding errors caused by vibration or offset, thereby ensuring the stability of the mesh welding quality. This transmission structure can adapt to the feeding needs of steel bars of different specifications and weights, has strong versatility and adaptability, and is suitable for various construction scenarios. Through optimized design of mechanical transmission, energy loss is reduced, energy utilization of drive component 23 is improved, and operating costs are reduced.

[0041] In some embodiments, the feeding unit 2 further includes a driven component 25, which includes a second main shaft 251, a second crank 252, and a second crankshaft 253. One end of the second crank 252 is connected to the second main shaft 251, and the other end of the second crank 252 is connected to the second crankshaft 253. The movable beam 22 is provided with a second seat plate 222. The second crankshaft 253 is connected to the second seat plate 222 via a second connecting arm 254. The second main shaft 251 is connected to the first main shaft 241 via a synchronization component 26. Two driven components 25 can be provided, and the second main shafts 251 of the two driven components 25 are connected via a coupling 210. By increasing the synchronous operation of the driven components 25 and the transmission component 24, the movable beam 22 can be subjected to more uniform force during the feeding process, reducing the problem of eccentric load in unilateral drive, thereby improving motion balance and stability. The driven component 25 and the transmission component 24 are connected by the synchronization component 26, ensuring the synchronicity of movement on both sides and preventing tilting or offset of the movable beam 22 during movement, further improving the accuracy and consistency of feeding. The dual-side drive design distributes the motion load of the movable beam 22, reducing wear on single-side transmission components, extending the service life of the feeding mechanism, and lowering maintenance costs. The addition of the driven component 25 enhances the overall load-bearing capacity of the feeding mechanism, enabling it to adapt to the feeding needs of heavier or larger steel bars, expanding the applicability of the mechanism. The dual-side drive design makes the movement of the movable beam 22 smoother, reducing vibration and noise, and improving the comfort and reliability of equipment operation. Dual-side synchronous drive can accelerate the movement speed of the movable beam 22 while maintaining stability, thereby further improving feeding efficiency and meeting the needs of large-scale production. The dual-side drive design reduces the safety risks caused by single-side drive failure, improving the operational safety of the equipment. The coordinated operation of the dual-side drives through the synchronization component 26 reduces energy loss and improves the energy utilization efficiency of the drive system.

[0042] Optionally, the synchronization component 26 includes a timing belt 261, a first timing pulley 262, and a second timing pulley 263. The first timing pulley 262 is connected to the first main shaft 241, and the first timing pulley 262 is connected to the second timing pulley 263 via the timing belt 261. The second timing pulley 263 is connected to the second main shaft 251. The synchronization component 26, composed of the timing belt 261, the first timing pulley 262, and the second timing pulley 263, ensures that the rotational movements of the first main shaft 241 and the second main shaft 251 are completely synchronized, thereby guaranteeing the consistency of movement on both sides of the movable beam 22 and avoiding tilting or offset problems caused by asynchrony. The timing belt 261 transmission method has good flexibility and buffering effect, which can reduce the impact and vibration during movement, making the movement of the movable beam 22 smoother and further improving the stability of the feeding process. Compared with gear or chain transmission, timing belt transmission has lower operating noise, improving the working environment and enhancing the operational comfort of the equipment. The timing belt 261 transmission structure is simple, requires no lubrication, and has low wear, reducing the maintenance frequency and cost of the equipment. The synchronous belt 261 drive boasts high transmission efficiency, effectively transferring power from the drive assembly 23 to the driven assembly 25, reducing energy loss and lowering operating costs. It can adapt to high speeds and large load variations, exhibiting strong versatility and adaptability, suitable for feeding steel bars of different specifications and weights. Its compact structure and easy installation simplify the overall design of the feeding mechanism, reducing manufacturing and assembly complexity. The synchronous belt 261 drive features overload protection against slippage, preventing equipment damage or accidents caused by sudden loads and improving operational safety. Furthermore, it reduces direct contact and wear between mechanical parts, extending the service life of transmission components and enhancing equipment reliability.

[0043] In some embodiments, the fixed beam 21 is equipped with a tensioning pulley 27, which presses against the synchronous belt 261. By setting the tensioning pulley 27 and pressing it against the synchronous belt 261, the tension of the synchronous belt 261 can be effectively adjusted and maintained, preventing the synchronous belt 261 from loosening due to long-term operation and ensuring the stability and reliability of the transmission. The tensioning pulley 27 keeps the synchronous belt 261 in an optimal tension state at all times, reducing the possible slippage or jumping of the synchronous belt 261 during transmission, thereby improving the accuracy and consistency of the transmission. Appropriate tension can reduce wear and fatigue of the synchronous belt 261, extend the service life of the synchronous belt 261, and reduce the replacement frequency and maintenance costs. The tensioning pulley 27 can absorb the minor vibrations and impacts of the synchronous belt 261 during operation, making the transmission process smoother and reducing noise and vibration during equipment operation. The setting of the tensioning pulley 27 makes the tension adjustment of the synchronous belt 261 more convenient and quick, simplifying the maintenance and debugging process of the equipment. The tensioner 27 automatically adjusts the tension of the synchronous belt 261 according to load changes, ensuring the stability and reliability of transmission under different working conditions. By maintaining the appropriate tension of the synchronous belt 261, transmission failure or slippage caused by slackness of the synchronous belt 261 is avoided, improving the safety of equipment operation. The tensioner 27 ensures close contact between the synchronous belt 261 and the synchronous pulley, reducing energy loss during transmission and improving transmission efficiency. The tensioner 27 allows the synchronous belt 261 to adapt to the tension requirements under different working conditions, enhancing the versatility and adaptability of the equipment.

[0044] Optionally, the drive assembly 23 includes a drive motor 231 and a reducer 232. The drive motor 231 is mounted on the base 1 via a frame 233, and is connected to the first main shaft 241 via the reducer 232. The combination of the drive motor 231 and the reducer 232 can convert the high-speed, low-torque motor output into low-speed, high-torque power, adapting to the high load requirements of rebar feeding and improving drive efficiency. The reducer 232 can precisely adjust the movement speed and position of the movable beam 22, avoiding human error and ensuring the stability of feeding and welding quality. Through the optimized transmission of the reducer 232, energy loss is reduced, and the energy utilization rate of the drive system is improved. The drive motor 231 is fixed to the base 1 via the frame 233, reducing the risk of vibration and displacement and ensuring the long-term stable operation of the drive assembly 23. The direct connection between the motor and the reducer 232 simplifies the transmission structure and reduces maintenance complexity.

[0045] In some embodiments, multiple movable beams 22 are provided, connected by connecting beams 28, which are perpendicular to the movable beams 22. The coordinated operation of multiple movable beams 22 allows for the simultaneous transport of more reinforcing bars, significantly increasing the single-batch feeding capacity and meeting the needs of large-scale production. The perpendicular arrangement of the connecting beams 28 with the movable beams 22 forms a stable frame structure, preventing deformation or displacement of the movable beams 22 due to uneven stress. Synchronous movement of multiple movable beams 22 ensures uniform distribution of the reinforcing bars, reducing the risk of misalignment during welding. It supports the parallel transport of reinforcing bars of various specifications, adapting to the diverse needs of complex construction scenarios.

[0046] Optionally, the fixed beam 21 is equipped with a sliding baffle 211. When the reinforcing bar 3 to be fed is delivered to the storage trough 29 at the end of the fixed beam 21, the drive motor 231 drives the first main shaft 241 to rotate, which in turn drives multiple sets of movable beams 22 to perform circular motion. The storage trough 29 at the end of the movable beam 22 follows the circular motion of the movable beam 22, delivering the reinforcing bar 3 to be fed into the groove of the sliding baffle 211. After the next process takes it away, the reinforcing bar 3 continues to be delivered into the groove of the sliding baffle 211. The sliding baffle 211 can constrain the position of the reinforcing bar, preventing the reinforcing bar from slipping due to vibration or inertia during handling, reducing material waste. It also reduces the risk of worker injury or equipment damage caused by accidental slippage of the reinforcing bar. It eliminates the need for frequent adjustment of the reinforcing bar position, reducing operational intensity and increasing automation.

[0047] In some embodiments, two feeding units 2 are provided. The two feeding units 2 can operate independently without interference and have a material storage function. The two feeding units 2 can operate sequentially or in parallel, significantly increasing the rebar conveying speed and meeting the demands of high-intensity railway construction. If one feeding unit 2 fails, the other feeding unit 2 can still maintain some capacity, reducing the risk of downtime. The two feeding units 2 can independently handle rebar of different specifications or batches, improving equipment flexibility. The dual-unit design, through coordinated operation, can reduce the single feeding stroke and shorten the overall operation cycle.

[0048] The feeding mechanism provided in this embodiment has the following general operating steps: First, the storage trough 29 on the movable beam 22 and the storage trough 29 on the fixed beam 21 are set to be consistent front to back and in the same position. When the previous process places the reinforcing bar 3 to be fed into the storage trough 29 on the fixed beam 21, the drive motor 231 works, driving the first main shaft 241 to rotate, which in turn drives multiple sets of movable beams 22 to perform circular motion. The storage trough 29 on the movable beam 22 drives the reinforcing bar 3 to be fed, and then sends the reinforcing bar 3 to be fed into the storage trough 29 of the next fixed beam 21, returning to the initial position, and continuing to drive the next reinforcing bar 3 and the previous reinforcing bar 3 to be fed. This process is repeated, and multiple reinforcing bars 3 can be fed forward at the same time, one grid at a time. When they are sent to the storage trough 29 at the end of the fixed beam 21, the drive motor 231 drives the first main shaft 241 to rotate, which in turn drives multiple sets of movable beams 22 to perform circular motion. The storage trough 29 at the end of the movable beam 22 follows the movable beam 22 to perform circular motion, sending the reinforcing bar 3 to be fed into the groove of the sliding baffle 211. After the next process takes it away, the reinforcing bar 3 is sent to the groove of the sliding baffle 211. The preceding feeding unit 2 and the following feeding unit 2 can choose to operate synchronously or asynchronously depending on the quantity of steel bars 3 to be fed. If the quantity of steel bars 3 to be fed during production is less than the quantity of storage troughs 29 on the movable beam 22, the preceding feeding unit 2 will transport all of its steel bars 3 to the following feeding unit 2. The preceding feeding unit 2 can then continue to transport steel bars 3 for the next type of mesh. The two units operate independently without interference. Once the end storage trough 29 on the fixed beam 21 of the preceding feeding unit 2 is full of steel bars, the drive motor 231 of the preceding feeding unit 2 will not work. It will resume operation after the movable beam 22 has transported all the steel bars 3 to be fed. The preceding feeding unit 2 can also perform the storage function.

[0049] Before feeding begins, it is essential to ensure that the storage trough 29 on the movable beam 22 and the storage trough 29 on the fixed beam 21 are aligned in the same horizontal position. This step is crucial because it ensures that the reinforcing bars can smoothly transition from the fixed beam 21 to the movable beam 22 during transport, preventing jamming or obstructed feeding due to positional discrepancies.

[0050] When the previous process places the reinforcing bar 3 to be fed into the storage trough 29 of the fixed beam 21, the drive motor 231 starts working. The drive motor 231 drives the first main shaft 241 to rotate, which in turn drives multiple sets of movable beams 22 to perform circular motion. The storage troughs 29 on the movable beams 22 move accordingly, bringing the reinforcing bar 3 to be fed out from the storage troughs 29 of the fixed beam 21 and gradually conveying it forward.

[0051] The movement of the movable beam 22 is periodic. After each complete circular motion, the steel bar 3 to be fed is conveyed to the storage trough 29 of the next fixed beam 21. At this time, the movable beam 22 returns to its initial position, ready to receive the next steel bar 3 to be fed. Through this cyclical movement, multiple steel bars 3 to be fed can be conveyed simultaneously, one section at a time, ensuring the orderly progress of the steel bars.

[0052] When the reinforcing bar 3 to be fed is conveyed to the storage trough 29 at the end of the fixed beam 21, the drive motor 231 starts again, driving the first main shaft 241 to rotate, and the movable beam 22 continues to perform circular motion. At this time, the storage trough 29 at the end of the movable beam 22 will bring the reinforcing bar 3 to be fed into the groove of the sliding baffle 211. The design of the sliding baffle 211 allows the reinforcing bar 3 to be fed to slide smoothly into the processing area of ​​the next process, waiting for subsequent processing.

[0053] This feeding mechanism can be configured with multiple feeding units 2. The preceding and following feeding units 2 can operate synchronously or asynchronously depending on the quantity of steel bars 3 to be fed. If the quantity of steel bars 3 to be fed is small, the preceding feeding unit 2 can immediately begin feeding the next batch of steel bars after completing the current batch, while the following feeding unit 2 continues processing the current batch. This design allows multiple feeding units 2 to work independently without interference, greatly improving production flexibility and efficiency.

[0054] When the number of steel bars 3 to be fed during production is less than the number of storage troughs 29 on the movable beam 22, the previous feeding unit 2 can transport all the steel bars 3 to be fed to the next feeding unit 2 before continuing to feed the next batch of steel bars. At this time, the end storage trough 29 on the fixed beam 21 of the previous feeding unit 2 can temporarily store the steel bars for subsequent processing. This design not only realizes the continuous feeding of steel bars but also has a storage function, ensuring the continuity of the production process.

[0055] To further optimize the feeding process, the operation of the drive motor 231 can be intelligently controlled according to actual needs. For example, when the end storage trough 29 on the fixed beam 21 is full of steel bars, the drive motor 231 of the previous feeding unit 2 can temporarily stop working and restart after the moving beam 22 completes the feeding of the current batch of steel bars. This intelligent control not only saves energy but also extends the service life of the equipment.

[0056] This feeding mechanism is also capable of adapting to steel bars of different specifications. By adjusting the dimensions of the storage troughs 29 on the movable beam 22 and the fixed beam 21, it can easily meet the feeding needs of steel bars of different diameters and lengths. This flexibility allows the feeding mechanism to be widely used in various steel bar processing production lines.

[0057] Throughout the feeding process, the mechanism's design fully considers safety and stability. The sliding baffle 211 not only ensures the smooth sliding of the reinforcing bars but also prevents accidental slippage or jamming during transport. Furthermore, the smooth operation of the drive motor 231 and the precise movement of the movable beam 22 further guarantee the safety and stability of the feeding process.

[0058] To ensure the long-term stable operation of the feeding mechanism, regular maintenance and upkeep are essential. Operators should regularly check the wear of key components such as the drive motor 231, movable beam 22, and fixed beam 21, and lubricate or replace them in a timely manner. In addition, the cleaning and maintenance of the storage trough 29 is also an important aspect of ensuring the smooth delivery of reinforcing bars.

[0059] The feeding mechanism provided in this embodiment achieves efficient and continuous conveying of reinforcing bars through ingenious design and intelligent control, and also possesses a storage function. Its flexible collaborative working mode and ability to adapt to reinforcing bars of different specifications make this mechanism widely applicable in reinforcing bar processing production lines. Simultaneously, the mechanism's safety and stability design ensures the smooth operation of the production process. Through regular maintenance and upkeep, this feeding mechanism can operate stably for a long time, providing strong support for the reinforcing bar processing industry.

[0060] This embodiment also provides a feeding method for feeding steel bars through the above-mentioned feeding mechanism, including the following steps:

[0061] Place the steel bar 3 to be fed into the storage trough 29 of the fixed beam 21;

[0062] The drive assembly 23 drives the movable beam 22 to move relative to the fixed beam 21 through the transmission assembly 24, so that the movable beam 22 transports the steel bars 3 to be fed on the fixed beam 21 from one storage tank 29 to another storage tank 29 along the feeding direction.

[0063] The automated feeding mechanism completely replaces traditional manual handling, significantly improving the efficiency of rebar feeding and meeting the needs of large-scale railway construction. The coordinated operation of the drive assembly 23 and transmission assembly 24 ensures precise and controllable movement trajectory of the movable beam 22, avoiding errors inherent in manual operation and guaranteeing the accuracy and consistency of rebar feeding. The automated feeding method reduces manual labor, avoids fatigue and safety hazards caused by handling heavy objects, and improves the working environment. Mechanized continuous feeding significantly shortens rebar feeding time, improves overall production efficiency, and accelerates construction progress. Precise rebar feeding ensures accurate rebar positioning during mesh welding, thereby improving welding quality stability and overall construction quality. Automated feeding reduces direct manual handling, lowering the risk of safety accidents caused by improper operation or fatigue. This method can efficiently handle the large volume of rebar feeding, adapting to the high-intensity operational requirements of large-scale railway construction. Precise feeding and positioning prevent rebar slippage or misalignment during handling, reducing material waste. The automated feeding method fully utilizes the performance of the feeding mechanism, improving equipment utilization and operating efficiency. By reducing labor requirements and material waste, overall operating costs were lowered, while the economic efficiency of construction was improved.
