Description

Technical Field

[0001] This utility model belongs to the technical field of iron tower galvanizing equipment, and specifically relates to an automatic material lifting machine for iron tower galvanizing. Background Technology

[0002] After hot-dip galvanizing the steel tower components in the galvanizing bath, the steel needs to be removed from the bath, and excess zinc liquid on its outer wall is blown off to ensure a consistent galvanized layer thickness. The current method uses an electrically controlled hydraulic cylinder to drive a lifting boom up and down for material lifting.

[0003] Patent application number 201820454055.3 discloses an automatic material lifting device for galvanizing iron towers, including a galvanizing tank. Two sliding rods are longitudinally arranged at both ends of one outer wall of the galvanizing tank. A movable installation assembly is sleeved on the two sliding rods. The movable installation assembly includes a moving plate, a pair of lifting cylinders, a pair of support plates, and a connecting block. The moving plate is sleeved on the two sliding rods. The pair of lifting cylinders are located on the top surface of the moving plate and are laterally fixed to the lifting plate. The connecting block is fixed to the mounting shaft at the top of the pair of support plates and has a moving cylinder on it. A material lifting assembly is provided on the outer end of the telescopic rod of the moving cylinder. The material lifting assembly includes a moving plate, a sliding plate, a material lifting cylinder, and a material lifting hook. The material lifting cylinder causes the moving plate to move horizontally along the sliding plate. The material lifting cylinder is located on the top surface of the outer end of the moving plate, and the material lifting hook is laterally fixed to the bottom end of the telescopic rod of the material lifting cylinder. This utility model is convenient and quick to use, making it easy to remove the steel material of the iron tower from the galvanizing tank, thus improving the galvanizing efficiency and making it suitable for widespread use. However, most iron towers require galvanizing of angle steel or steel pipes, which are relatively long. Existing material lifting equipment can easily cause the workpiece to shift, thus affecting the galvanizing effect and making it easy for the workpiece to fall off. Utility Model Content

[0004] In view of this, the present invention provides an automatic material lifting machine for galvanizing iron towers. The start-up drive component adjusts the distance between the two first support frames through a double threaded rod, and fixes the workpiece through a clamping assembly. The lifting machine is connected to the connecting component, which drives the support frame to be lifted onto the galvanizing tank. It is suitable for fixing workpieces of different sizes, and at the same time prevents the workpiece from shifting during lifting and falling off.

[0005] The technical solution is as follows: An automatic material lifting device for galvanizing iron towers includes a support frame and a galvanizing tank. A double threaded rod is rotatably mounted on the support frame. A drive component is detachably mounted on the support frame. The drive component is connected to the double threaded rod via a transmission mechanism. When the drive component is activated, it drives the double threaded rod to rotate through the transmission mechanism. Two first support frames are slidably mounted on the support frame. The double threaded rod is threadedly connected to the two first support frames. The double threaded rod drives the two first support frames to move synchronously relative to each other or in opposite directions. Each of the two first support frames is equipped with a clamping assembly for clamping the workpiece. A connecting component is provided on the first support frame.

[0006] During use, the above technical solution works as follows: the start-up drive unit adjusts the distance between the two first support frames through the double threaded rod, and fixes the workpiece through the clamping assembly. It is connected to the connecting component through the hoist, which drives the support frame to be lifted onto the galvanizing tank. It is suitable for fixing workpieces of different sizes, and at the same time prevents the workpiece from shifting during hoisting and falling off.

[0007] Preferably, the support frame has two symmetrical first sliding grooves, and the two ends of the first support frame are fixedly provided with first sliding blocks, which are slidably installed in the first sliding grooves.

[0008] Preferably, the support frame has a first mounting hole, and the two ends of the double threaded rod are fixedly provided with a first rotating shaft, which is rotatably installed in the first mounting hole.

[0009] Preferably, the transmission mechanism includes a first transmission gear fixedly mounted on a first rotating shaft, and a second transmission gear fixedly mounted at the output end of the drive component, wherein the first transmission gear meshes with the second transmission gear.

[0010] Preferably, the connecting component includes a pull ring fixedly mounted on the first support frame.

[0011] Preferably, the clamping assembly includes a second support frame fixedly mounted on a first support frame. A first limiting component is fixedly provided at one end of the second support frame. A plurality of second limiting components are slidably mounted on the second support frame. An adjustment component is provided between the first limiting component, the second limiting component, and two adjacent second limiting components. The distance between the first limiting component, the second limiting component, and two adjacent second limiting components is adjusted by the adjustment component.

[0012] Preferably, the second limiting component includes a support plate, and multiple arc-shaped plates are fixedly arranged on both sides of the support plate. The multiple arc-shaped plates are linearly and evenly distributed along the support plate. The first limiting component and the second limiting component have the same structure. The support plate on the first limiting component is connected and fixed to one end of the second support frame. A second sliding block is fixedly arranged on the support plate of the second limiting component. A second sliding groove is opened on the second support frame. The second sliding block is slidably installed in the second sliding groove.

[0013] Preferably, the arc-shaped plate is fixedly provided with a plurality of evenly distributed protrusions.

[0014] Preferably, the adjusting assembly includes a double-threaded tube, on the outer wall of which a nut is fixedly installed. A first screw is provided on one side of the support plate of the first limiting assembly and on both sides of the support plate of the second limiting assembly. The first screws on the first limiting assembly and the adjacent second limiting assembly are threadedly connected to the double-threaded tube. The two first screws on the two adjacent second limiting assemblies are threadedly connected to the double-threaded tube. The distance between the two first screws is adjusted synchronously by operating the double-threaded tube.

[0015] During use, the above technical solution involves simultaneously adjusting the distance between the two first screws using the double-threaded pipe, thereby adjusting the distance between the two adjacent support plates. The workpiece is then clamped and fixed by the arc-shaped plates on the two adjacent support plates. The protrusion reduces the contact area between the arc-shaped plates and the workpiece, thus improving the integrity of the galvanized coating.

[0016] Preferably, the connecting component includes a connecting frame, on which two symmetrical mounting seats are fixedly mounted. A second pin is provided between the two mounting seats on the connecting frame, and a first pin is provided between the two mounting seats on the first support frame.

A pull ring is fixedly provided at the upper middle end of the connecting frame, and bushings are fixedly provided at both ends of the transmission rod. The first pin and the second pin are rotatably mounted in the two bushings respectively.

[0017] During use, the above technical solution works by using the pull rings on the connecting frame to lift the support frame, ensuring that the center of gravity of the support frame and the workpiece are aligned with the force applied during lifting, thereby improving the stability of the workpiece lifting.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] 1. The start-up drive unit adjusts the distance between the two first support frames through the double threaded rod, and fixes the workpiece through the clamping assembly. It is connected to the connecting part through the hoist, and drives the support frame to be lifted onto the galvanizing tank. It is suitable for fixing workpieces of different sizes, and at the same time prevents the workpiece from shifting during hoisting and causing the workpiece to fall.

[0020] 2. The distance between the two first screws is adjusted synchronously by operating the double threaded pipe, thereby adjusting the distance between the two adjacent support plates. The workpiece is clamped and fixed by the arc plate on the two adjacent support plates. The contact area between the arc plate and the workpiece is reduced by the protrusion, thereby improving the integrity of the galvanization of the workpiece.

[0021] 3. The support frame is lifted by the pull ring on the connecting frame, so that the center of gravity of the support frame and the workpiece are on the same straight line as the force applied during lifting, thereby improving the stability of the workpiece lifting.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] like Figures 1 to 10 As shown, an automatic material lifting device for galvanizing iron towers includes a support frame 1 and a galvanizing tank 9. A double threaded rod 5 is rotatably mounted on the support frame 1. A drive component 8 is detachably mounted on the support frame 1. The drive component 8 is connected to the double threaded rod 5 through a transmission mechanism. When the drive component 8 is activated, it drives the double threaded rod 5 to rotate through the transmission mechanism. Two first support frames 10 are slidably mounted on the support frame 1. The double threaded rod 5 is threadedly connected to the two first support frames 10. The double threaded rod 5 drives the two first support frames 10 to move synchronously relative to each other or in opposite directions. Each of the two first support frames 10 is provided with a clamping assembly for clamping the workpiece. A connecting component is provided on the first support frame 10.

[0037] Two symmetrical first sliding grooves 2 are provided on the support frame 1, and first sliding blocks 11 are fixedly provided at both ends of the first support frame 10. The first sliding blocks 11 are slidably installed in the first sliding grooves 2.

[0038] The support frame 1 has a first mounting hole 3, and the two ends of the double threaded rod 5 are fixedly provided with a first rotating shaft 4, which is rotatably installed in the first mounting hole 3.

[0039] The transmission mechanism includes a first transmission gear 6 fixedly mounted on the first rotating shaft 4, and a second transmission gear 7 fixedly mounted at the output end of the drive component 8. The first transmission gear 6 and the second transmission gear 7 mesh with each other.

[0040] Specifically: the drive component 8 is a forward and reverse servo motor. The drive component 8 is mounted on the support frame 1 by bolts and nuts 19. The first support frame 10 has screw holes 12. The threads of the two screw holes 12 are opposite. The double threaded rod 5 is provided with two sections of external threads with opposite threads. The two sections of external threads of the double threaded rod 5 are respectively threaded to the two screw holes 12.

[0041] The connecting component includes a pull ring 13 fixedly installed on the first support frame 10, which connects the two hooks on the crane to the two pull rings 13 respectively.

[0042] In actual operation: The forward and reverse servo motor is started, which drives the first transmission gear 6 to rotate through the second transmission gear 7. The first transmission gear 6 drives the first rotating shaft 4 to rotate through the first rotating shaft 4. The first rotating shaft 4 drives the double threaded rod 5 to rotate through the double threaded rod 5. The first support frame 10 moves along the support frame 1 through the double threaded rod 5. The first sliding block 11 moves along the first sliding groove 2 to adjust the distance between the two first support frames 10 and keep the center of the two first support frames 10 coincides with the center of the support frame 1. The workpiece is fixed by the clamping assembly. The two hooks on the crane are connected to the two pull rings 13. The crane lifts the support frame 1 and moves it to the galvanizing tank 9, so that the support frame 1 rests on the upper side wall of the galvanizing tank 9. The connection between the hooks and the pull rings 13 is disconnected. The crane can complete other lifting work. After galvanizing is completed, the support frame 1 is lifted again.

[0043] Example 2

[0044] Based on Embodiment 1, the clamping assembly includes a second support frame 14 fixedly installed on the first support frame 10. A first limiting component 16 is fixedly provided at one end of the second support frame 14. A plurality of second limiting components 17 are slidably installed on the second support frame 14. Adjustment components are provided between the first limiting component 16 and the second limiting component 17, as well as between two adjacent second limiting components 17. The distance between the first limiting component 16 and the second limiting component 17, as well as between two adjacent second limiting components 17, can be adjusted by adjusting the adjustment components.

[0045] The second limiting component 17 includes a support plate 1701. Multiple arc-shaped plates 1703 are fixedly arranged on both sides of the support plate 1701. The multiple arc-shaped plates 1703 are linearly and evenly distributed along the support plate 1701. The first limiting component 16 and the second limiting component 17 have the same structure. The support plate 1701 on the first limiting component 16 is connected and fixed to one end of the second support frame 14. A second sliding block 1702 is fixedly arranged on the support plate 1701 of the second limiting component 17. A second sliding groove 15 is opened on the second support frame 14. The second sliding block 1702 is slidably installed in the second sliding groove 15.

[0046] Specifically: the cross-section of the second sliding groove 15 is U-shaped, and the cross-section of the second sliding block 1702 is U-shaped, corresponding to the second sliding groove 15.

[0047] Multiple evenly distributed protrusions 1704 are fixedly installed on the curved plate 1703.

[0048] The adjustment assembly includes a double-threaded tube 18, on the outer wall of which a nut 19 is fixedly installed. A first screw 26 is provided on one side of the support plate 1701 on the first limiting assembly 16 and on both sides of the support plate 1701 on the second limiting assembly 17. The first screw 26 on the first limiting assembly 16 and the adjacent second limiting assembly 17 are threadedly connected to the double-threaded tube 18. The two first screws 26 on the two adjacent second limiting assemblies 17 are threadedly connected to the double-threaded tube 18. The distance between the two first screws 26 is adjusted synchronously by operating the double-threaded tube 18.

[0049] Specifically: the two first screws 26 have opposite thread directions, and the two internal threads of the double-threaded tube 18 have opposite directions and are threadedly connected to the two first screws 26.

[0050] In actual operation: the double-threaded tube 18 between the first limiting component 16 and the second limiting component 17 is rotated, which drives the first screws 26 at both ends to move synchronously, thereby adjusting the distance between the two first screws 26. The workpiece is clamped by the arc-shaped plates 1703 on the two adjacent support plates 1701. The protrusions 1704 contact the workpiece surface, reducing the contact area for clamping the workpiece. Multiple workpieces are linearly and evenly distributed on the support plates 1701, with gaps reserved between the workpieces to improve the uniformity and integrity of the galvanization. Then, the double-threaded tube 18 between the two adjacent second limiting components 17 is rotated to adjust the distance between the support plates 1701 on the two adjacent second limiting components 17. This method is suitable for clamping and fixing workpieces of different diameters. Example

[0051] Based on Example 1 or Example 2, such as Figure 9 and Figure 10As shown, the connecting component includes a connecting frame 24. Two symmetrical mounting seats 20 are fixedly installed on both the connecting frame 24 and the first support frame 10. A second pin 25 is provided between the two mounting seats 20 on the connecting frame 24. A first pin 21 is provided between the two mounting seats 20 on the first support frame 10. A transmission rod 22 is movably installed between the first pin 21 and the second pin 25. A pull ring 13 is fixedly installed at the upper middle end of the connecting frame 24. Bushings 23 are fixedly installed at both ends of the transmission rod 22. The first pin 21 and the second pin 25 are rotatably installed in the two bushings 23 respectively.

[0052] Specifically: There are two second pins 25, which are symmetrically installed on the connecting frame 24 to connect the hook of the crane to the pull ring 13 on the connecting frame 24.

[0053] In actual operation: the support frame 1 is lifted by the pull ring 13 on the connecting frame 24, so that the center of gravity of the support frame 1 and the workpiece are on the same straight line as the force applied during lifting, thereby improving the stability of the workpiece lifting.

[0054] The working principle of this utility model is as follows: The forward and reverse servo motor is started, which drives the first transmission gear 6 to rotate through the second transmission gear 7. The first transmission gear 6 drives the first rotating shaft 4 to rotate through the first rotating shaft 4. The double threaded rod 5 rotates through the first rotating shaft 4. The double threaded rod 5 drives the first support frame 10 to move along the support frame 1. The first sliding block 11 moves along the first sliding groove 2 to adjust the distance between the two first support frames 10 and keep the center of the two first support frames 10 coincides with the center of the support frame 1. The workpiece is fixed by the clamping assembly. The two hooks on the crane are connected to the two pull rings 13. The crane lifts the support frame 1 and moves it to the galvanizing tank 9, so that the support frame 1 rests on the upper side wall of the galvanizing tank 9. The connection between the hooks and the pull rings 13 is disconnected, and the crane can complete other lifting work. After galvanizing is completed, the support frame 1 is lifted again.

[0055] The double-threaded tube 18 between the first limiting component 16 and the second limiting component 17 is rotated, which drives the first screws 26 at both ends to move synchronously, thereby adjusting the distance between the two first screws 26. The workpiece is clamped by the arc-shaped plates 1703 on the two adjacent support plates 1701. The protrusions 1704 contact the workpiece surface, reducing the contact area for clamping the workpiece. Multiple workpieces are linearly and evenly distributed on the support plates 1701, with gaps reserved between the workpieces to improve the uniformity and integrity of the galvanizing. Then, the double-threaded tube 18 between the two adjacent second limiting components 17 is rotated to adjust the distance between the support plates 1701 on the two adjacent second limiting components 17. This method is suitable for clamping and fixing workpieces of different diameters.
