Description

Technical Field

[0002] With the continuous acceleration of infrastructure construction in my country, the country's investment in various types of infrastructure has continued to increase. In particular, in the construction of key projects such as high-grade highways, high-speed railways, urban integrated pipelines and urban rail transit, tunnel projects, as a key component, are increasing year by year. These tunnel projects are not only huge in number, but also often pass through complex and changeable geological environments. Therefore, in the construction process of tunnel projects, scientific and effective support measures must be taken to ensure the stability of the tunnel structure and the safety of the overall construction in view of the particularity of different types of bedrock geological conditions. As one of the core support structures in tunnel construction, the steel arch frame bears important bearing and protection functions, and plays an irreplaceable role in preventing deformation of the tunnel surrounding rock and ensuring construction safety and progress.

[0003] However, the traditional processing method of steel arches is highly dependent on manual operation, and a large amount of manual intervention is required in each link from material preparation to finished product assembly. This processing mode is not only inefficient in production, but also severely restricted by subjective factors such as the operator's proficiency and the number of laborers. In actual operation, it is often difficult to accurately control the dimensional accuracy, assembly angle and welding quality of the steel arch, which affects the support effect and even leaves safety hazards. In addition, the processing of steel arches involves a series of high-risk processes such as cutting, bending, and welding. These processes are not only labor-intensive, but also very likely to cause work-related accidents, posing a serious threat to the life safety and physical health of operators.

[0004] At the same time, with the progress of the times and the development of social economy, the construction industry is facing unprecedented challenges, among which the rising labor costs and the serious shortage of professional skilled workers are particularly prominent. This situation not only further aggravates the labor cost burden of the steel arch frame processing industry, but also makes it difficult for the traditional manual processing mode to adapt to the rapid development needs of modern tunnel engineering construction in terms of efficiency, quality and cost control. Therefore, exploring and promoting a new efficient, accurate and safe steel arch frame processing system has become an important issue that needs to be solved in the current tunnel engineering construction field.

The loading robot arm 101 transports the lifted workpiece forward to the cutting movable rack 202, and the cutting movable rack 202 There is a motor on 02 to drive the chain, so that the rollers on the cutting movable frame 202 transport the I-beam back and forth. There is a flush sawing machine device 201 at each end of the cutting movable frame 202. The flush sawing machine device 201 is equipped with positioning and sawing functions, which can cut off the burrs on the end face of the I-beam raw material to ensure the stability of subsequent welding. After the sawing machine flushes one end, the cutting movable frame 202 transports the I-beam to the other end, and then the flush processing of the other end is realized. After the two ends are flushed, they are lifted by the transfer rack assembly 13 and transported to the continued welding conveying rack 403. The continued welding conveying rack 403 transports forward and transports the I-beam to the position of the continued welding fixed frame 401. The continued welding fixed frame 401 is equipped with a positioning mechanism, a clamping mechanism, and a detection mechanism. When the tail of the previous workpiece is transmitted to the detection mechanism , the detection mechanism detects that there is no material, and then the front clamping mechanism clamps the previous I-beam, and the rear welding conveyor frame 403 transmits the next workpiece forward. After it is transmitted to the detection switch, the clamping mechanism clamps the rear I-beam, and then the welding robots 402 on both sides start welding at the butt joint of the I-beams. After the welding is completed, the clamping mechanism is released, and the rotary cold bending machine 501 continues to transmit the I-beam forward. After it is transmitted to the required size of the workpiece, the cold cutting saw 502 cuts the workpiece. If it is necessary to cut a hole on the web of the I-beam, the plasma cutting robot automatically cuts the hole. The cut workpiece is automatically adjusted in angle and position by the rotary transfer assembly 6. After adjusting the position, the clamping cylinder 604 of the rotary transfer assembly 6 releases the workpiece, and the electric roller 706 The workpiece is automatically transported left and right. After being transported to the end positioning baffle 703, the detection switch on the end positioning baffle 703 controls the roller lifting frame 705 to descend, and the workpiece falls on the adjustable width chain conveyor frame 702. The adjustable width chain conveyor frame 702 moves forward and backward with the workpiece. The two adjustable width chain conveyor frames 702 can be controlled separately. Each adjustable width chain conveyor frame 702 is equipped with two detection switches. The first detection switch is a deceleration signal, and the second detection switch is an in-position stop signal. After the I-beam stops conveying, the centering baffles on both sides are aligned, and then the adjustable width chain conveyor frame 702 continues to transport the workpiece forward to the baffle plate welding assembly 8. After being transported to the first welding station, the baffle rod 803 and the clamping mechanism 804 position the workpiece. While transporting the workpiece,The connecting plate handling robot 805 grabs the connecting plate from the head plate conveyor rack 903, and then places it on the positioning mechanism for precise positioning. The camera on the connecting plate welding robot 806 at the first station takes a picture of the end face of the workpiece, and after identifying the position of the workpiece, transmits the data to the connecting plate handling robot 805. The connecting plate handling robot 805 then grabs the connecting plate and places it on the end face of the I-beam. The connecting plate welding robot 806 spot welds, and the connecting plate handling robot 805 moves away. The connecting plate welding robot 806 at the first station completes the welding of the welds that need to be welded. Then the blocking rod 803 and the clamping mechanism 804 move downward, and the semi-finished welded workpiece is continuously transported forward by the adjustable width chain conveyor frame 702. After being transported to the flip positioner 802, the flip positioner 802 lifts the workpiece and rotates it 180°, so that the weld that has not been welded just now is on top. Then the image shooting device carried by the robot at the second station automatically takes pictures and identifies the weld position. At the same time, the next workpiece repeats the previous action and is transported to the first station, which can meet the first and second stations, and the four connecting plate welding robots 806 weld at the same time. After welding is completed, the flip positioner 802 places the welded workpiece with the arch facing upward, and the cantilever beam 1004 automatically moves back and forth to the C-type opening position of the flip positioner 802 to automatically grab the finished workpiece, and the finished workpiece is placed on the finished product storage rack 11. After waiting for the welding of five workpieces, the workers will transport the finished product away for subsequent processing. At the same time, the head plate laser cutting machine 901 places the raw steel plate in the processing area, and the head plate laser cutting machine 901 automatically cuts it into the required connecting plates. After all the cutting is completed, the head plate transfer robot 902 automatically grabs the cut connecting plates and places them in the head plate storage bin 904. After all the connecting plates are placed in the head plate storage bin 904, the head plate transfer robot 902 automatically places the connecting plates to be welded on the head plate conveyor rack 903. The head plate conveyor rack 903 automatically conveys the connecting plates to the corners, and the push cylinder pushes the connecting plates to the vertical head plate conveyor rack 903. Then the connecting plates are conveyed forward along the head plate conveyor rack 903, and when they are conveyed to the positioning plate, the detection signal feeds back the signal that the connecting plates have been delivered to the position, and the connecting plate handling robot 805 grabs them.
