Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline welding equipment, and in particular relates to a cutting sleeve welding production line for coal mine pipelines. Background Art

[0002] With the rapid development of my country's economy, the use of pipelines in coal mines has developed rapidly. The investment in pipelines used in coal mines is large. Pipes must be used in water supply, drainage, slurry discharge, ventilation, gas discharge, etc. in coal mines. Among coal mining enterprises that use pipelines, about 95% of them use steel pipelines. The most important thing in laying water and gas pipelines is the connection of pipes to pipes. The "two-to-one" method is often used in coal mine pipeline construction. The pipeline is cut into a specific length on the well, and the ring is manually inserted at a specific distance from both ends of the pipeline. Manual arc welding is used to complete the ring welding operation, and then it is sent to the underground construction site. The pipeline is mechanically docked on site to complete the laying of long transportation pipelines.

[0003] Coal mine pipeline cutting, pipe fixing, sleeve ring installation, welding, and material discharge are all manual operations, and the forming quality requirements of the fixed sleeve welds at specific distances at both ends of the pipeline are high, requiring complex welding methods and welding processes, resulting in a waste of manpower costs and time. Therefore, the study of automatic cutting and welding production lines, improving the forming quality and welding speed of welds, and adopting automatic pipe cutting and full-position automatic welding of fixed sleeve rings at the pipe ends can reduce labor and time costs, especially for the welding of small-diameter and long-sized coal mine transportation pipelines. It has unique advantages. Therefore, the development of automatic cutting and welding production lines is an urgent task for the current coal mine pipeline construction. Utility Model Content

[0064] Place the pipe 11 to be cut on the shelf 1, start the feeder 5, move the second feeder 5.2 to the side of the shelf 1, move the first feeder 5.1 and the second feeder 5.2 to below the pipe 11 on the shelf 1, start the second hydraulic pump station 5.8, extend the piston rod of the second hydraulic cylinder 5.7, lift the support plate 5.5, so that the first material support racks 5.4 on both sides lift the pipe, then move the first feeder 5.1 and the second feeder 5.2, place the pipe 11 on the push rack 2 along the transport line, and then move the second feeder 5.2 to the track 3 between the push rack 2 and the collar device 8;

[0065] Start the first motor 2.1 to rotate the roller 2.2, driving the pipe 11 to move backward. When the rear end surface of the pipe 11 abuts the positioning plate 6, the movement stops, and the cutting device 4 is moved to the cutting position of the pipe. The second feeding car 5.2 and the third feeding car 5.3 are started and moved along the track 3 between the pushing frame 2 and the collar device 8 to the vicinity of the pushing frame 2.

[0066] During the cutting operation, the cutting device 4 is first fine-tuned so that the pipe cutter 4.1 is aligned with the pipe cutting point, the first hydraulic pump station 4.2 is started, the piston rod of the first hydraulic cylinder 4.3 is extended, and its top plate is lifted up, and the cutting device 4 moves to the left at the same time. When the left movement is completed, the roller of the pipe cutter is at a certain distance from the pipe 11, and the top plate continues to lift up to support the pipe. The propulsion mechanism next to it plays an auxiliary supporting role, and the pipe cutter 4.1 is started. The pipe cutter head is pressed down to cut the pipe 11 into two sections of pipe, and then the pipe cutter head is lifted, the first hydraulic cylinder 4.3 retracts, and the pipe cutter 4.1 is lowered. The cut pipe 11 is placed on the roller 2.2. After the pipe cutter 4.1 is lowered to a certain position, the cutting device 4 moves to the right to leave the pipe, and the second feeding car 5.2 and the third feeding car 5.3 are started to transport it away, and then the front end is placed on the roller 2.2. The cut pipe continues to move backward, and when the pipe 11 hits the positioning plate 6, it stops moving;

[0067] The second feeding car 5.2 and the third feeding car 5.3 on the track 3 move to the bottom of the pipeline 11, start the second hydraulic pump station 5.8, the piston rod of the second hydraulic cylinder 5.7 extends, lifts the support plate 5.5, and makes the first material support frame 5.4 lift the pipeline. The two feeding cars 5.2 and 5.3 move to the right along the track 3 synchronously, and stop when they reach the collar device 8. The second feeding car 5.2 and the third feeding car 5.3 continue to move to the right, and then lower the support plate 5.5, and place the pipeline 11 on the supporting rollers 8.30 of the two collar devices 8. After continuing to lower and detach from the pipeline, the second feeding car 5.2 and the third feeding car 5.3 move to the left, return to the vicinity of the propulsion frame 2, and stop, waiting to enter the next working cycle;

[0068] Start the second motor 8.1, the second motor drives the reducer 8.5 to drive the output shaft 8.2 to rotate through the coupling 8.3, the output shaft 8.2 drives the first transmission shaft 8.4 to rotate through the transmission chain 8.6, and the driving gear 8.7 rotates accordingly. Since the driving gear 8.7 and the driven gear 8.9 are both incomplete gears, when the toothed parts of the two are meshed, the second transmission shaft 8.8 is driven to rotate. When the driving gear 8.7 and the driven gear 8.9 are disengaged, the driven gear 8.9 and the second transmission shaft 8.8 stop moving, and the intermittent motion of the driven gear 8.9 and the second transmission shaft 8.8 is realized through the driving gear 8.7 and the driven gear 8.9;

[0069] According to the structural characteristics of the incomplete gear mechanism, when the toothed portion of the driving gear 8.7 meshes with the driven gear 8.9, the driven gear 8.9 is pushed to rotate; when the toothed portion of the driving gear 8.7 is disengaged from the driven gear 8.9, the driven gear 8.9 stops moving; when the driving gear 8.7 rotates continuously, the driven gear 8.9 obtains an intermittent motion of starting and stopping; and when the toothed portion of the driving gear 8.7 rotates to the driven gear 8.9 again, since the driven gear 8.9 stops moving and the toothed portion cannot mesh, The driving gear 8.7 and the driven gear 8.9 are provided with a toggle pin 8.10 and a toggle lever 8.11. When the rest time reaches a preset time, the toggle lever 8.11 toggle the pin 8.10 to rotate together, pushing the driven gear 8.9 to rotate, so that when the toothed portion of the driving gear 8.7 rotates to the meshing position again, the toothed portion of the driven gear 8.9 can mesh with the toothed portion of the driving gear 8.7 again, and continue to mesh and rotate. The incomplete gear is designed so that when the driving gear 8.7 rotates one circle, the driven gear 8.9 also rotates one circle at the same time;

[0070] When the incomplete gears are meshed, the second transmission shaft 8.8 drives the driving crank 8.12 to rotate, and the driving crank 8.12 drives the connecting rod 8.14 to move through the pin shaft 8.13, and the connecting rod 8.14 drives the slider connecting rod 8.16 to slide up and down in the slide groove of the slide groove rod 8.15, thereby driving the lifting rod 8.17 and the plumb bob jack 8.18 to slide up and down, and the plumb bob jack 8.18 slides upward and stops when it lifts the material ring 8.19 to the highest point;

[0071] Start the push rod cylinder 8.21, push the push rod push plate 8.22 and the horizontal push rod 8.20 forward, the horizontal push rod 8.20 passes through the push ring mold 8.25 and the material ring 8.19 in turn, and stops when the front end is against the end of the pipe 11, then the driving gear 8.7 is meshed with the driven gear 8.9, driving the plumb push rod 8.18 to slide downward and disengage from the material ring 8.19, then the push mold cylinder 8.23 ​​pushes the mold push plate 8.21 and the push ring mold 8.25 to move forward, and the push ring mold 8.25 pushes the material ring 8.19 to move forward along the horizontal push rod 8.20, until the material ring 8.19 reaches and is sleeved on the predetermined welding position of the outer wall of the pipe 11, then the push mold cylinder 8.23 ​​and the push rod cylinder 8.24 return to their original positions;

[0072] When the second transmission shaft 8.8 rotates, the ring-filling mechanism is driven to operate at the same time, and the crank 8.33 rotates accordingly, and the double crank connecting plate 8.31 is driven to make a circular motion through the crank coupling 8.34. When the plumb bob 8.18 moves to the lowest point, the pallet push block 8.32 moves to the highest point and is inserted into the pallet shifting slot 8.29. The pallet push block 8.32 continues to move, pushing the pallet 8.27 forward, and the moving distance is exactly equal to the distance between the adjacent push rod perforations 8.28. At this time, the next push rod perforation 8.28 and the placed material ring 8.19 just move to the top of the plumb bob 8.18, and the pallet push block 8.32 moves out of the pallet shifting slot 8.29 and enters the next cycle;

[0073] The collaring devices 8 on both sides of the pipeline 11 perform collaring operations on both ends at the same time. When the collaring operation is completed, welding operations are performed. The pressure roller 7.2 is moved to the top of the pipeline 11 through the vertical slide rail 7.4 and the horizontal slide rail 7.3. The pressure roller frame drives the pressure roller 7.2 to descend along the vertical slide rail 7.4 to press the pipeline 11. The position angle of the welding gun 7.1 is adjusted to align it with the inner weld of the material ring 8.19. The pressure roller 7.2 starts to rotate, driving the pipeline 11 to rotate and perform welding. After welding is completed, the pressure roller 7.2 and the welding gun 7.1 are withdrawn, and the welding device 7 moves to both sides and returns to the initial position;

[0074] After the welding operation is completed, the first unloading trolley 9.1 and the second unloading trolley 9.2 move along the track 3 to the bottom of the pipe 11, and the second material support frame 9.3 is lifted by the hydraulic cylinder. The pipe 11 is placed in the arc groove of the second material support frame 9.3 and lifted up, and moves to the right along the track and moves the pipe 11 to the side of the shelving rope rack 10. At this time, the hydraulic cylinder close to the side of the shelving rope rack 10 descends, and the hydraulic cylinder away from the side rises, causing the support plate to tilt toward the side of the shelving rope rack 10, and the pipe 11 rolls from the arc groove onto the shelving rope rack 10, completing the unloading operation.

[0075] by Fig.11Taking the clockwise rotation of the driving gear shown as an example, when the meshing position of the driving gear 8.7 and the driven gear 8.9 is at the mapping position 1B, the whole mechanism stops moving, at this time, the plumb push rod 8.18 is at the highest point, and the double crank connecting plate 8.31 is at the lowest point. In the locking arc section A, the relative positions of the plumb push rod 8.18 and the double crank connecting plate 8.31 remain unchanged. At the mapping position 3D, the whole mechanism starts to move, the plumb push rod 8.18 starts to descend, and the double crank connecting plate 8.31 starts to rise. At the mapping position 2C The plumb bob 8.18 and the double crank connecting plate 8.31 simultaneously complete the switching between the highest point and the lowest point respectively. The plumb bob 8.18 moves to the lowest point, and the double crank connecting plate 8.31 moves to the highest point. By concentrating one circle of movement of the driven gear 8.9 on one side of the driving gear 8.7, the length of the locking arc A is extended, providing a longer action time for the ring pushing mechanism to put on the ring, avoiding the lower transmission mechanism being forced to stop due to the ring putting process of the ring pushing mechanism, and halving the required number of stops of the second motor 8.1.
