Description

Technical Field

[0001] The invention relates to the field of steel structure processing, and in particular to a turning machine and a welding platform having the same. Background Art

[0002] With the development of construction technology, steel structures have been increasingly widely used due to their short construction period, fast construction speed, and high load-bearing strength. Steel structure processing is a very important part of steel structure engineering, but there are still some urgent problems to be solved in steel structure processing. In particular, the riveting and welding process of steel components, as a key process in steel structure processing, has become an important bottleneck restricting the industry's progress in improving efficiency and quality due to its cumbersome operation, high dependence on manual labor, and safety issues.

[0003] The specific problems are as follows:

[0004] On the one hand, because the specifications and lengths of steel components vary, and the sizes and positions of different component parts are also inconsistent, the riveting and welding of parts are still done manually, which is a labor-intensive operation with low equipment participation in the steel structure factory processing process. The riveting and welding construction of steel components generally places the main body of the steel component on the work surface. After the parts on one side of the component are riveted and welded, the component needs to be turned over, and then the riveting and welding work on the back is carried out. Due to the heavy weight of the component, it is generally turned over by crane during construction. During the operation, the component is prone to instability. The turning process of heavy weight components is easy to cause damage to the crane electric hoist and wire rope, which brings safety hazards to the turning operators and other welding personnel working in the work area. The riveting and welding of steel structures requires the cooperation of multiple people, the construction efficiency is low, and there are certain safety hazards in the construction process.

[0005] On the other hand, in the riveting and welding process, the gas shielded welding machine is an indispensable tool. In order to weld different parts of steel components and adapt to the complex environment of the production workshop, the wire feeder needs to be manually moved to different locations in the workshop. The moving process is not only time-consuming and laborious, but also has the risk of cable entanglement. The wire feeder is placed on the ground and is prone to mechanical damage during construction. In addition, the large amount of welding smoke generated during welding not only deteriorates the working environment, but also directly threatens the health of welders, becoming a major obstacle to improving production efficiency and working conditions.

[0006] In view of the above situation, the present invention aims to develop a highly integrated automation solution, which integrates mechanical flipping, welding and flipping safety interlock, movement of welding machine wire feeder and welding smoke recovery device, and is committed to solving the safety problem of steel component flipping operation, realizing efficient and automated movement of gas shielded welding machine wire feeder, and effective purification and recovery of welding smoke. It increases the application of equipment in the riveting and welding process of steel components, improves work efficiency, realizes standardized operation, enhances the level of green construction, and effectively improves the working environment.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figures 1 to 5 As shown, the turning machine of the present invention comprises: a crossbeam 10, which is arranged on a supporting base surface; two supporting mechanisms 20, which are arranged at both ends of the crossbeam 10, and each supporting mechanism 20 is provided with a mounting cavity 210; two telescopic mechanisms, which are arranged one-to-one with the two supporting mechanisms 20, and each telescopic mechanism is movably arranged in a corresponding mounting cavity 210 along a vertical direction; two bearing devices 30, which are arranged one-to-one with the two telescopic mechanisms, and each bearing device 30 is arranged on the top of the corresponding telescopic mechanism, so that the corresponding bearing device 30 moves along the corresponding direction under the drive of the telescopic mechanism; a transmission chain 40, which is wound around the two bearing devices 30 and the two supporting mechanisms 20; wherein the two bearing devices 30 and the crossbeam 10 enclose a turning space 50 for placing at least part of the chain body of the transmission chain 40, so that the part to be turned over is placed on the chain body in the turning space 50, so that when the transmission chain 40 moves under the drive of the telescopic mechanism, the part to be turned over is driven.

[0036] It can be seen that the turning machine of the present invention adopts a crossbeam and two supporting mechanisms as the basic structure, and accurately adjusts the tension of the transmission chain through two telescopic mechanisms to ensure that the transmission chain always maintains stability during the turning process; the linkage between the telescopic mechanism and the carrying device enables the chain to be fine-tuned according to the characteristics of the workpiece to be turned, thereby achieving precise control of the workpiece and avoiding instability or damage of the workpiece during the turning process. The design of the telescopic mechanism makes it possible to perform the tension adjustment process of the chain without manual intervention, thereby improving the safety and efficiency of the operation, reducing the labor intensity of the operator, and also reducing possible human errors during the operation, improving production accuracy, and solving the problems of inconvenient turning of the turning machine in the prior art during the steel structure processing and great potential safety hazards of turning.

[0037] like Figure 1 and Figure 2As shown, the turning machine also includes a driving component 70, which is arranged on one side of the supporting mechanism 20, and the driving component 70 includes a driving motor 710 and a reducer 720, wherein the output shaft of the driving motor 710 is connected to the input shaft of the reducer 720, the output shaft of the reducer 720 is connected to the sprocket, and the sprocket is meshed with the transmission chain 40. The driving motor 710 can provide a stable and powerful power output, and through the cooperation with the reducer 720, the effective transmission of power and the amplification of torque are realized, ensuring that the transmission chain 40 can smoothly and efficiently drive the steel component to turn over. This design optimizes the power system of the turning machine, improves the turning speed and accuracy, and thus significantly improves the work efficiency in the riveting and welding process.

[0038] Preferably, each supporting mechanism 20 is further provided with a protective cover 220, and a protective space 230 is provided in the protective cover 220, and a part of the chain body of the transmission chain 40 is located in the protective space 230. The protective space 230 protects the transmission chain 40 from damage by external factors, such as the intrusion of dust and foreign objects, and wear in a harsh working environment, thereby extending the service life of the chain and reducing the maintenance cost and repair frequency of the equipment.

[0039] Preferably, each carrying device 30 also includes: two lifting arms 310, the two lifting arms 310 are arranged relative to each other to form a placement space 320, the relative arrangement of the two lifting arms 310 can provide a stable working platform, ensure the balance and stability of the steel structure during the flipping process, reduce flipping accidents caused by uneven weight distribution of the workpiece, and improve the safety of the operation; multiple transmission shafts 330, the multiple transmission shafts 330 are arranged at intervals in the placement space 320 along the extension direction of the lifting arms 310, and the transmission shafts 330 are rotatably arranged to carry the transmission chain 40. The deployment of multiple transmission shafts 330 can evenly distribute the weight of the steel structure, avoid local overload, enhance the overall bearing capacity of the carrying device 30 and the flipping capacity of the flipping machine, and is suitable for steel structures of different specifications and weights.

[0040] Specifically, a guide mechanism 340 is provided at one end of each carrying device 30, and the guide mechanism 340 is fixedly connected to the lifting arm 310, so as to drive the guide mechanism 340 to move accordingly when the lifting arm 310 moves in the vertical direction; wherein, each guide mechanism 340 is provided at one end of the corresponding lifting arm 310 close to another lifting arm 310, so as to guide the transmission chain 40. The guide mechanism 340 can effectively guide and adjust the position of the transmission chain 40, ensure that the chain remains stable when the lifting arm 310 moves, avoid the chain from deflecting or derailing during the flipping process, and improve the stability and reliability of the flipping machine operation.

[0041] Optionally, each guide mechanism 340 is provided with a guide shaft 350, the guide shaft 350 is rotatably provided, and the transmission chain 40 is wound around each guide shaft 350. The use of the guide shaft 350 reduces the direct friction between the transmission chain 40 and the fixed structure, reduces the wear of the chain and the guide shaft, and prolongs the service life of the equipment. By reducing the maintenance requirements, the long-term operating cost is reduced.

[0042] like Figure 1 As shown, a hydraulic support 80 is provided in the telescopic mechanism, and the hydraulic support is drivingly connected to the telescopic mechanism, so that under the drive of the hydraulic support 80, the telescopic mechanism drives the lifting arm 310 and the guide mechanism 340 to move, so that the transmission chain 40 is arranged in a direction close to or away from the crossbeam 10, so as to flip the belt flipping member. The use of the hydraulic support 80 enables the flipping machine to dynamically adjust the position of the transmission chain 40 according to the size and weight of the workpiece, thereby realizing the precise flipping of steel components of different specifications, and improving the versatility and adaptability of the equipment.

[0043] like Figure 3 As shown, the present invention also provides a welding platform, including: two running tracks 2; a welding machine 1, which is arranged on a side of the welding platform away from the running tracks 2; a flipping machine 4, which is the above-mentioned flipping machine, and the flipping machine 4 is arranged on one running track 2; a welding auxiliary device 3, which is arranged on another running track 2, so as to weld the to-be-welded after the flipped part is flipped. The present invention integrates key equipment such as a welding machine, a flipping machine and a welding auxiliary device into one platform, realizes continuous automated operation from workpiece flipping to welding, greatly improves welding efficiency and operation continuity, and realizes flipping of the workpiece through the flipping machine, ensuring the rapid conversion of the workpiece between different welding surfaces, and at the same time, the welding auxiliary device can automatically complete the welding preparation work, cooperate with the welding machine to improve welding quality and operation safety.

[0044] like Figure 4As shown, the welding auxiliary device 3 also includes: a column support structure 8, which is arranged on the support base; the column support structure 8 provides a stable foundation for the entire welding auxiliary device 3, ensuring the stability and bearing capacity of the entire structure when bearing the weight of the welding wire supply unit 6 and the operating reaction force during the welding process, reducing the welding quality problems caused by structural instability; a telescopic cantilever 5, which is installed on one side of the column support structure 8 to be telescopically adjusted as needed during the welding process. The setting of the telescopic cantilever 5 enables the welding wire supply unit 6 to be flexibly adjusted according to the workpiece position and welding requirements during the welding process. Telescopicity greatly expands the scope of welding operations, and can not only handle plane welding, but also meet the welding needs of three-dimensional structures, improving the versatility and adaptability of welding equipment; the welding wire supply unit 6 is arranged at the end of the telescopic cantilever 5, and is located above the turning space 50 of the turning machine 4, so that after the turning part to be turned is completed, the welding wire is supplied under the drive of the telescopic cantilever 5. The welding wire supply unit 6 is located above the turning space 50, which reduces obstacles on the welding wire supply path, ensures smooth supply of welding wire during welding, reduces welding interruption time, and improves welding efficiency and continuous operation capability.

[0045] Preferably, the welding auxiliary device 3 further includes a fume recovery pipe 7, which is mounted on the telescopic cantilever 5 and located on one side of the welding wire supply unit 6, so as to recover the fume generated by welding during welding. The fume recovery pipe 7 in the present invention is mounted on the telescopic cantilever 5 and is adjacent to the welding wire supply unit 6. This design shortens the distance from the generation of fume to its recovery, reduces the time for fume to diffuse in the workshop, and avoids the fume affecting the operator's sight and the cleanliness of the working area, thereby improving welding efficiency and working comfort.

[0046] like Figure 5As shown, the welding platform of the present invention also includes: a control system, the control system includes a PLC input module 100, a PLC output module 200 and a relay module 300, the relay module 300 includes an ascending intermediate relay KA3, a descending intermediate relay KA4, a forward intermediate relay KA1, a backward intermediate relay KA2 and a welding isolation intermediate relay KA5 arranged in parallel, the ascending intermediate relay KA3 and the descending intermediate relay KA4 are respectively connected to the first driving module of the turning machine 4 for driving its telescopic mechanism, so that by operating the button on the PLC input module 100, the first driving module is triggered to drive the telescopic mechanism to ascend Or descend; the forward intermediate relay KA1 and the backward intermediate relay KA2 are respectively connected to the second drive module of the turning machine 4 for driving its transmission chain 40 to rotate, so as to trigger the second drive module to drive the transmission chain 40 to rotate forward or reverse by operating the buttons on the PLC input module 100; wherein, the welding isolation intermediate relay KA5 is used to receive the welding signal, so as to short-circuit the ascending intermediate relay KA3, the descending intermediate relay KA4, the forward intermediate relay KA1 and the backward intermediate relay KA2 after triggering the welding isolation intermediate relay KA5, so as to complete the interlocking of the ascending and descending of the telescopic mechanism and the forward and reverse rotation of the transmission chain 40.

[0047] The operation process of the control system in the present invention is as follows:

[0048] Press the "Up" button, the PLC controls the hydraulic station motor to rotate, the up intermediate relay KA3 is closed, the solenoid valve is powered, and the hydraulic drive equipment starts to move up;

[0049] Press the "down" button, the PLC controls the hydraulic station motor to rotate, the lowering intermediate relay KA4 is energized, the solenoid valve is powered, and the hydraulic drive equipment descends;

[0050] Press the "Forward" key, the forward intermediate relay KA1 is energized, giving the inverter a forward signal, and the chain drives the workpiece to rotate clockwise;

[0051] Press the "Reverse" key, the reverse intermediate relay KA2 is energized, giving the inverter a reverse signal, and the chain drives the workpiece to rotate counterclockwise;

[0052] When rising, falling, or rotating forward or reverse, press the "pause" button to stop the equipment, thereby realizing the 360-degree flip function of the steel component in place.

[0053] When the external welding signal is given, the welding isolation intermediate relay KA5 starts to interlock with the lifting and rotating operations to achieve the safety interlocking function of the welding operation;

[0054] At the same time, the fan start relay KA6 is started to form a linkage with the automatic smoke recovery and purification device to realize the automatic recovery and purification function of welding smoke. The smoke purifier is set to delay 50 seconds after welding to ensure that the welding smoke is completely absorbed.

[0055] Preferably, the control system in the present invention introduces a PLC input module 100 and an output module 200, so that the welding platform can automatically perform the flipping and positioning of the workpiece before welding through a preset program, ensuring that the preparation work before welding is efficient and accurate, reducing the uncertainty and errors of manual operation, and improving the degree of automation of the entire operation process; through the key operation on the PLC input module, the operator can intuitively and easily control the lifting and lowering of the telescopic mechanism of the flip machine 4 and the forward and reverse rotation of the transmission chain 40, achieving rapid response, reducing waiting time and operation difficulty, and improving the flexibility and efficiency of the operation.

[0056] Preferably, the setting of the welding isolation intermediate relay KA5 in the present invention ensures that during the welding process, the movement of the telescopic mechanism of the flip machine 4 and the transmission chain 40 is safely blocked, thereby realizing the interlocking between the welding and flipping operations, and avoiding the degradation of welding quality or potential operational safety risks caused by equipment movement; and the parallel setting of the relay module 300 not only simplifies the control circuit, but also enhances the fault protection capability of the system. When a relay fails, the system can continue to maintain basic functions through other relays, thereby improving the reliability and continuous operation capability of the equipment.

[0057] Since the steel component turning machines in the prior art are designed for a single purpose and in a variety of forms, but mainly have only a turning function, there is no integrated set of equipment for steel component welding and turning safety interlocking and automatic welding smoke recovery during steel component riveting and welding operations.

[0058] Therefore, the advantages of the turning machine and the welding platform having the same of the present invention are as follows:

[0059] 1. The function of 360° flipping in situ of riveted and welded steel components is realized, and the flipping machine is used in riveting and welding processing;

[0060] 2. Realize the safety interlocking function between riveting welding and automatic flipping to ensure the safety of operators;

[0061] 3. Realize the mechanical movement of the wire feeder of the gas shielded welding machine and the automatic recovery of welding fume, and realize the integrated linkage control of the above three functions.

[0062] In the present invention, the riveting welding and automatic flipping safety interlocking function and the mechanical movement of the gas shielded welding wire feeder in the work area can effectively improve the construction efficiency, ensure the safety of the operation, improve the construction working environment, improve the riveting efficiency of steel components, increase production capacity, and reduce equipment maintenance costs; reduce the damage of welding smoke to the working environment and workers, and realize standardized operation and green construction.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] The turning machine of the present invention comprises: a crossbeam 10, which is arranged on a supporting base surface; two supporting mechanisms 20, which are arranged at both ends of the crossbeam 10, and each supporting mechanism 20 is provided with a mounting cavity 210; two telescopic mechanisms, which are arranged one-to-one with the two supporting mechanisms 20, and each telescopic mechanism is movably arranged in a corresponding mounting cavity 210 along a vertical direction; two bearing devices 30, which are arranged one-to-one with the two telescopic mechanisms, and each bearing device 30 is arranged on the top of the corresponding telescopic mechanism, so that the corresponding bearing device 30 moves along the corresponding direction under the drive of the telescopic mechanism; a transmission chain 40, which is wound around the two bearing devices 30 and the two supporting mechanisms 20; wherein the two bearing devices 30 and the crossbeam 10 enclose a turning space 50 for placing at least part of the chain body of the transmission chain 40, so that the part to be turned over is placed on the chain body in the turning space 50, so that when the transmission chain 40 moves under the drive of the telescopic mechanism, the part to be turned over is driven to turn over.

[0065] It can be seen that the turning machine of the present invention adopts a crossbeam and two supporting mechanisms as the basic structure, and accurately adjusts the tension of the transmission chain through two telescopic mechanisms to ensure that the transmission chain always maintains stability during the turning process; the linkage between the telescopic mechanism and the bearing device enables the chain to be fine-tuned according to the characteristics of the workpiece to be turned over, thereby achieving precise control of the workpiece and avoiding instability or damage to the workpiece during the turning process. The design of the telescopic mechanism makes the tension adjustment process of the chain unnecessary for manual intervention, which improves the safety and efficiency of the operation, reduces the labor intensity of the operator, and also reduces possible human errors during the operation, thereby improving production accuracy. The turning machine in the prior art is inconvenient to turn over during the steel structure processing, and has a large potential safety hazard.
