Description

Technical Field

[0001] The present application relates to the field of transportation, and in particular to a high-strength steel structural member transportation production line. Background Art

[0002] At present, steel workpieces are usually treated by pickling and galvanizing to remove surface scale and rust and improve corrosion resistance. Pickling is to remove surface impurities by immersing the workpiece in an acid solution, while galvanizing is to coat a layer of zinc on the surface of the workpiece to enhance corrosion resistance. These two processes are widely used in industrial production, especially in the steel processing industry, and are of great significance for improving product quality and extending service life.

[0003] In the related art, a pickling chamber and a galvanizing chamber are usually arranged under a ring truss. The ring truss hooks a hanger. After the workpiece is hung on the hanger, the ring truss drives the hanger to move back and forth between the pickling chamber and the galvanizing chamber. After the workpiece is generally pickled, the workpiece is moved to the zinc chamber for galvanizing by the truss. The hanger used for galvanizing is the same hanger used for pickling.

[0004] The above-mentioned related technologies have the following defects: the hanger used for galvanizing is the same hanger used for pickling, and is hooked by the gantry crane throughout the process. When the workpiece is galvanized, zinc is also sprayed on the hanger. When the workpiece needs to be hoisted again for pickling, the zinc on the hanger easily reacts chemically with the acid, and the zinc ion in the pickling tank is too high and needs to be treated, which has a high treatment cost. Summary of the invention

[0005] In order to improve the problem of excessive zinc ions in the pickling tank, the present application provides a high-strength steel structure transportation production line.

[0006] The high-strength steel structure transportation production line provided in this application adopts the following technical solution: A high-strength steel structure transportation production line, comprising an annular truss crane, a pickling chamber, a transfer rail, a transfer vehicle and a galvanizing chamber, wherein the annular truss crane comprises a bridge, an annular slide rail, a first suspension arm and a plurality of first limit sliders, wherein the annular slide rail is horizontally mounted on the bridge, and the plurality of first limit sliders are all slidably connected to the annular slide rail; The first suspension arm is arranged below the first limit slider and is installed on a plurality of the first limit sliders in a liftable manner, and is used to pick up the hanger; The pickling chamber is arranged on the side of the annular slide rail; The transfer guide rail is horizontally arranged below the annular slide rail, the first end and the second end of the transfer guide rail are both spaced apart and arranged directly below the annular slide rail, and the middle portion of the transfer guide rail is located in the pickling chamber; The transfer vehicle is slidably connected to the transfer guide rail and is used to carry the hanger; The galvanizing chamber is arranged directly below a portion of the transfer guide rails, and when the first suspension arm is located directly above the galvanizing chamber, it can extend into the galvanizing chamber.

[0007] By adopting the above technical solution, if the workpiece does not need to be re-hanged, multiple transfer carts are set at the first end of the transfer guide rail, and the hanger is placed on the transfer cart at the first end of the transfer guide rail. The workpiece is hung on the hanger. After the transfer cart slides along the transfer guide rail into the pickling chamber, the pickling chamber pickles the workpiece, and the transfer cart carries the hanger back to the first end of the transfer guide rail. Then, the first boom slides to the top of the first end of the transfer guide rail, descends and picks up the hanger from the transfer cart, and then drives the first boom to move the pickled workpiece into the galvanizing chamber. The galvanizing chamber galvanizes the pickled workpiece, and then the first boom slides again to the top of the first end of the transfer guide rail, and the hanger is placed on the transfer cart. The above steps can be repeated according to production needs to realize the recycling of a hanger. If the workpiece needs to be re-hanged, multiple transfer carts are set at both the first and second ends of the transfer guide rail.

After the pickling is completed, the pickled workpiece is moved to the second end of the transfer rail, a new hanger is placed on an idle transfer vehicle at the second end of the rail, and the pickled workpiece is moved to the new hanger to replace the workpiece. Then the first boom moves the new hanger to the galvanizing chamber for galvanizing. When the workpiece needs to be replaced, the hanger only participates in pickling or galvanizing, and does not participate in both pickling and galvanizing. Therefore, the zinc ions on the hanger will not enter the pickling tank, thereby improving the problem of excessive zinc ions in the pickling tank.

Through the mutual cooperation between the first linear guide rail 31, the second linear guide rail 32 and the third linear guide rail 33, the directional and stable movement of the transfer vehicle 4 on the transfer guide rail 3 and the precise limit of the area where the transfer vehicle 4 needs to pause on the transfer guide rail 3 are realized, thereby improving the reliability of the system.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The transfer vehicle 4 includes a bottom plate 41, two limit brackets 42 and a plurality of legs 43. The plurality of legs 43 are arranged below the bottom plate 41, and one end of the legs is rotatably connected to the bottom plate 41, and the other end is provided with a walking wheel 44. The two limit brackets 42 are arranged above the bottom plate 41 at intervals, and one end is connected to the bottom plate 41, and the other end is provided with a clamping groove 4201, and the two clamping grooves 4201 are respectively used to clamp the two ends of the hanger 6. The connecting rod 451 is arranged below the bottom plate 41, and the end away from the ball 452 is connected to the bottom plate 41.

The transfer vehicle 4 is supported by the support legs 43 and the running wheels 44, and the transfer vehicle 4 is driven by the running wheels 44. One end of the support leg 43 is rotatably connected to the bottom plate 41, which facilitates the reversal of the running wheels 44, and then facilitates the adjustment of the running direction of the transfer vehicle 4.

[0044] Reference Figure 1 , Figure 2 and Figure 3 , the connecting rod 451 is installed on the bottom plate 41 in a liftable manner. In the embodiment of the present application, when the transfer guide rail 3 is set, in order to ensure the flatness of the factory floor 7, the transfer guide rail 3 is embedded in the floor of the factory. At this time, the ball 452 can enter one of the first guide groove 3101, the second guide groove 3201 and the third guide groove 3301 by lowering the connecting rod 451 to achieve directional movement of the transfer vehicle 4. When the transfer vehicle 4 is not needed, the ball 452 can be moved above the floor of the factory by raising the connecting rod 451. At this time, the transfer vehicle 4 can move freely in any direction through the walking wheels 44.

[0045] Reference Figure 1 , Figure 2 and Figure 3 , the connecting rod 451 is hinged to the bottom plate 41. In the embodiment of the present application, when the transfer guide rail 3 is set, in order to ensure the flatness of the factory floor 7, the transfer guide rail 3 is embedded in the floor of the factory. At this time, the ball 452 can enter one of the first guide groove 3101, the second guide groove 3201 and the third guide groove 3301 by rotating the connecting rod 451 downward to achieve directional movement of the transfer vehicle 4. When the transfer vehicle 4 is not needed, the ball 452 can be moved above the floor of the factory by rotating the connecting rod 451 upward. At this time, the transfer vehicle 4 can move freely in any direction through the walking wheels 44.

[0046] Reference Figure 1 , Figure 2 and Figure 5 Both ends of the galvanizing chamber 5 in the length direction and the top of the galvanizing chamber 5 have openings, a portion of the annular slide rail 12 is located directly above the galvanizing chamber 5, and a portion of the annular slide rail 12 directly above the galvanizing chamber 5 is arranged along the length direction of the galvanizing chamber 5.

[0047] The bottom of the galvanizing chamber 5 is provided with a zinc pot 51 arranged along the length direction of the galvanizing chamber 5. A lifting door 52 is provided at one end of the galvanizing chamber 5 in the width direction.

[0048] Reference Figure 1 , Figure 2 and Figure 5In the embodiment of the present application, the first boom 14 can smoothly pass through the galvanizing chamber 5. The lifting door 52 is convenient for workers to add zinc liquid and maintain the interior of the galvanizing chamber 5.

[0049] Reference Figure 1 , Figure 2 and Figure 3 A plurality of driving components 53 are connected between the lifting door 52 and the galvanizing chamber 5. The driving components 53 include a pull rod 531 and two second lifting members 533. The pull rod 531 is arranged above the lifting door 52. A hinge 532 is connected between the middle of the pull rod 531 and the top of the lifting door 52. The two second lifting members 533 are both arranged above the pull rod 531 and symmetrically arranged on both sides of the hinge 532. The first ends of the two second lifting members 533 are respectively connected to the two ends of the pull rod 531, and the second ends of the two second lifting members 533 are both installed on the galvanizing chamber 5.

[0050] Reference Figure 1 , Figure 2 and Figure 3 In the embodiment of the present application, the second lifting member 533 is a second electric hoist. When the driving assembly 53 is set, a single second lifting member 533 has a pulling force to drive the lifting door 52 to rise and fall. Furthermore, the driving assembly 53 composed of two second lifting members 533 and the pull rod 531 has a double insurance effect. When one of the second lifting members 533 is damaged, the other lifting member still has enough pulling force to drive the lifting door 52 to rise, thereby improving the stability of the operation of the lifting door 52.

[0051] The implementation principle of a high-strength steel structure transportation production line in the embodiment of the present application is: If the workpiece does not need to be re-hanged, multiple transfer carts 4 are set at the first end of the transfer guide rail 3, and the hanger 6 is placed on the transfer cart 4 at the first end of the transfer guide rail 3, and the workpiece is hung on the hanger 6. After the transfer cart 4 slides along the transfer guide rail 3 into the pickling chamber 2, the linear truss crane 24 moves the hanger 6 into the pickling tank 21. After the pickling tank 21 pickles the workpiece, the linear truss crane 24 resets the hanger 6, and the transfer cart 4 carries the hanger 6 back to the first end of the transfer guide rail 3 along the original route. Then, the first lifting arm 14 slides to above the first end of the transfer guide rail 3, descends and picks up the hanger 6 from the transfer cart 4, and then drives the first lifting arm 14 to move the pickled workpiece into the galvanizing chamber 5. The galvanizing chamber 5 galvanizes the pickled workpiece, and then the first lifting arm 14 slides to above the first end of the transfer guide rail 3 again, and places the hanger 6 on the transfer cart 4. The above steps can be repeated according to production needs to achieve the recycling of a hanger 6.

[0052] If the workpiece needs to be re-mounted, a plurality of transfer vehicles 4 are provided at the first end and the second end of the transfer guide rail 3 . The workpiece is hung on the hanger 6 at the first end of the transfer guide rail 3. After the transfer vehicle 4 carries the workpiece and slides along the transfer guide rail 3 into the pickling chamber 2, the linear truss crane 24 moves the hanger 6 into the pickling tank 21. After the pickling tank 21 pickles the workpiece, the linear truss crane 24 resets the hanger 6, and the transfer vehicle 4 carries the pickled workpiece to the second end of the transfer guide rail 3. A new hanger 6 is placed on the idle transfer vehicle 4 at the second end of the guide rail, and the pickled workpiece is moved to the new hanger 6 to achieve the replacement of the workpiece. Then, the first crane arm 14 moves the new hanger 6 into the galvanizing chamber 5 for galvanizing, so that when the workpiece needs to be replaced, the hanger 6 only participates in pickling or galvanizing, and does not participate in both pickling and galvanizing, so that the zinc ions on the hanger 6 will not enter the pickling tank 21, thereby improving the problem of excessive zinc ions in the pickling tank 21.
