Description

Technical Field

[0001] This utility model relates to a production line transport device, and more particularly to a steel arch frame fully automatic welding production line transport rack. Background Technology

[0002] A tunnel is an engineering structure buried in the earth's strata, a form of human utilization of underground space. To maintain the structural strength of the excavated tunnel, a support frame needs to be installed inside the tunnel. The upper part of the support frame is an arched steel beam. The steel arch beam is made by processing steel profiles. Currently, the existing method of retrieving steel profiles is to manually take the steel profiles from the transverse conveyor and transfer them to the longitudinal conveyor. Then, the steel arch beam is processed by a rotary cold bending machine, a cutting saw, a transfer conveyor, a flexible welding mechanism, a handling robot, and a finished product conveyor. Manually taking the steel profiles from the transverse conveyor increases the cost of manual steel handling. Utility Model Content

The steel sections placed on the steel section unloading area are hoisted one by one onto the left side of the upper surface of the transverse conveyor. The transverse conveyor conveys the steel sections to the right. When the steel section is directly above the top plate, the transverse conveyor stops running and the lifting cylinder B is activated. The cylinder B drives the top plate and limit block to move upward. The top plate lifts the steel section upward. During this process, the top plate drives the guide rod to slide upward along the linear bearing. The cylinder B stops running.

[0025] It also includes a transfer rack 6, which is respectively installed between the longitudinal conveyor rack A3, longitudinal conveyor rack B4 and longitudinal conveyor rack C5;

[0026] The transfer rack 6 includes a rectangular frame 601, guide rails 602, sliders 603, cylinder A 604, base plate 605, cylinder B 606, top plate 610, and connecting plate 612. Guide rails 602 are fixedly installed on the front and rear parts of the upper surface of the rectangular frame 601, and two sliders 603 are slidably installed on each guide rail 602. Cylinder A 604 is fixedly installed on the left side wall of the rectangular frame 601, and the main shaft of cylinder A 604 slides through the left part of the rectangular frame 601. Connecting plate 612 is fixedly installed at the end of the main shaft of cylinder A 604. The same base plate 605 is fixedly installed on the upper part of each slider 603. Connecting plate 612 is fixedly connected to base plate 605. The lower part of cylinder B 606 is fixedly connected to the middle part of the upper surface of base plate 605. Top plate 610 is fixedly installed at the end of the main shaft of cylinder B 606.

[0027] Each of the aforementioned transfer racks 6 is respectively matched with the transverse conveyor rack 2.

[0028] At the same time, such as Figure 4 In this embodiment, rectangular tubes 607 are respectively provided on the front and rear sides of the cylinder B606, and the lower part of the rectangular tubes 607 is fixedly connected to the base plate 605. Linear bearings 608 are fixedly provided on the upper part of the inner sidewall of each rectangular tube 607, and guide rods 609 are slidably engaged on each linear bearing 608. Each guide rod 609 is fixedly connected to the adjacent top plate 610 on the upper side, so as to prevent the top plate 610 from rotating through the rectangular tubes 607, linear bearings 608, and guide rods 609.

[0029] At the same time, such as Figure 4 In this embodiment, limiting blocks 611 are fixedly installed on the front and rear parts of the left and right side walls of the top plate 610, respectively, to restrict the movement of the steel section supported on the top plate 610.

[0030] The working principle of this specific embodiment is as follows: the steel section to be processed is placed on the steel section feeding area 1, and the steel plate to be welded is placed in the steel plate feeding area 102 of the flexible welding mechanism 10.

[0031] The transverse conveyor 2, longitudinal conveyor A3, longitudinal conveyor B4, longitudinal conveyor C5, rotary cold bending machine 7, cutting saw 8, transfer conveyor 9, flexible welding mechanism 10, handling robot 101, and finished product conveyor 11 are activated respectively. The steel sections placed on the steel section feeding area 1 are hoisted one by one onto the left side of the upper surface of the transverse conveyor 2. The transverse conveyor 2 transports the steel sections to the right. When the steel section is located directly above the top plate 610, the operation of the transverse conveyor 2 is stopped, and the lifting cylinder B606 is activated. The cylinder B606 drives the top plate 610 and the limit block 611 to move upward. The top plate 610 lifts the steel section upward. During this process, the top plate 610 drives the guide rod 609 to slide upward along the linear bearing 608, and the operation of the cylinder B606 is stopped.

[0032] Lifting cylinder A604, the main shaft of cylinder A604 drives connecting plate 612, connecting plate 612 drives base plate 605, base plate 605 directly or indirectly drives cylinder B606, rectangular tube 607, linear bearing 608, guide rod 609, top plate 610, limit block 611, top plate 610 drives the section steel to move to the right to the upper side of longitudinal conveyor frame A3, longitudinal conveyor frame B4, and longitudinal conveyor frame C5, and stops cylinder A604 from running;

[0033] The retracting cylinder B606 drives the top plate 610 and the limit block 611 to move downwards. The top plate 610 drives the steel section to fall onto the longitudinal conveyor frame A3, longitudinal conveyor frame B4, and longitudinal conveyor frame C5. During this process, the top plate 610 drives the guide rod 609 to slide down along the linear bearing 608 to the initial position, stopping the operation of the cylinder B606.

[0034] The retracting cylinder A604 drives the connecting plate 612, which in turn drives the base plate 605. The base plate 605 directly or indirectly drives the cylinder B606, rectangular tube 607, linear bearing 608, guide rod 609, top plate 610, and limit block 611 to move to the left to the initial position, thus stopping the cylinder A604 from moving.

[0035] During the forward movement of the steel profiles via longitudinal conveyor frames A3, B4, and C5, the rotary cold bending machine 7 bends the steel profiles. The rotary cold bending machine 7 then moves the steel profiles forward to the appropriate position under the cutting saw 8. The operation of longitudinal conveyor frames A3, B4, C5, and the rotary cold bending machine 7 is then stopped. The cutting saw 8 cuts the steel profiles to the appropriate size. The cutting saw 8 is then turned on to transport the cut steel profiles to the appropriate position on the transfer conveyor frame 9. The operation of the cutting saw 8 and the transfer conveyor frame 9 is then stopped. The handling robot 101 moves the steel plates placed in the steel plate placement area 102 to the left and right side walls of the steel profiles. The welding robot on the flexible welding mechanism 10 welds the steel plates and steel profiles together. During this process, the flexible welding mechanism 10 moves the welded steel plates and steel profiles forward to the finished product conveyor frame 11. The finished product conveyor frame 11 transports the welded products forward to the appropriate position and transfers the welded steel profiles and steel plates away.

[0036] In summary, in use, the rectangular frame 601, guide rail 602, slider 603, cylinder A 604, base plate 605, cylinder B 606, rectangular tube 607, linear bearing 608, guide rod 609, top plate 610, limit block 611, and connecting plate 612 are assembled into a transfer rack 6, which reduces the cost of manual handling of steel profiles.

[0037] The beneficial effects of this utility model are: 1. It reduces the cost of manually handling steel profiles. 2. It facilitates the prevention of top plate rotation through rectangular tubes, linear bearings, and guide rods. 3. It restricts the movement of the steel profiles supported on the top plate through limiting blocks.
