Description

Technical Field

[0001] This utility model relates to the field of galvanizing technology, and in particular to a metal lifting tool and a hot-dip galvanizing processing device. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection. It mainly involves placing the workpiece into the galvanizing bath using lifting equipment.

[0003] A search revealed a prior art lifting device for hot-dip galvanized metal parts (publication number: CN222225739U), comprising a hanger, a movable seat, a movable block, a sleeve, an adjusting rod, and a clamping block. The hanger is generally strip-shaped, with a square-shaped movable seat at the bottom, and a movable groove inside the movable seat. The movable blocks are arranged in pairs and symmetrically in the movable groove. The sleeve is fixedly installed at the bottom of the movable block. One end of the adjusting rod is nested in the sleeve, and the other end is provided with a retainer. The clamping block and the retainer are engaged with each other. A clamping plate is provided at the bottom of the clamping block, and a fixing head is provided on the side of the clamping plate facing the central axis of the hanger.

[0004] Existing technology uses two close-to-each clamping blocks to hold the end of the pipe, which can only perform galvanizing operations on one pipe at a time, thus limiting efficiency. The part of the pipe that is clamped is close to the galvanizing solution, making it susceptible to high temperatures that can affect its service life and stability. There is room for optimization in the workpiece hoisting method of existing technology.

[0005] Therefore, we propose a metal lifting tool and a hot-dip galvanizing processing device. Utility Model Content

[0006] This utility model mainly solves the technical problem of low efficiency in clamping a single pipe at a time, and provides a metal lifting tool and a hot-dip galvanizing processing device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a metal lifting device, comprising: Two symmetrically distributed mounting bases are provided, each of which is rotatably mounted with a rotating base. Several guide rods are fixedly provided between the two rotating bases, and several protrusions are fixedly installed at the ends of the rotating bases. The rotating bases form a splash-proof surface through the protrusions. A suspension structure is provided on a guide rod for suspending workpieces. The suspension structure includes a rotating body, a hook body, and a sealing end cap. The hook body is fixedly connected to the rotating body, and the rotating body is rotatably connected to the guide rod. Both ends of the rotating body are provided with sealing end caps for sealing, and the sealing end caps are threadedly connected to the rotating body.

[0008] In a preferred embodiment of this utility model, the guide rod is a cylinder, and multiple guide rods are arranged in a ring array at the end of the rotating seat.

[0009] In a preferred embodiment of this utility model, the rotating body is a circular tube with an inner diameter larger than that of the guide rod, and the hook is an arc-shaped rod integrally formed with the rotating body, with the hook located on the circumferential surface of the rotating body.

[0010] In a preferred embodiment of this utility model, an annular groove is provided at the end of the rotating body, and a boss is formed by the annular groove. The boss is threaded, and the sealing end cap is threadedly connected to the boss.

[0011] In a preferred embodiment of this utility model, the suspension structure further includes a first sealing ring and a second sealing ring, the end of the sealing end cap is detachably fitted with the second sealing ring, and the inner wall of the rotating body is detachably fitted with the first sealing ring.

[0012] In a preferred embodiment of this utility model, the end of the sealing cap is provided with a groove, the second sealing ring is located in the groove, the inner wall of the rotating body is provided with an annular groove, and the first sealing ring is installed in the annular groove.

[0013] A hot-dip galvanizing processing apparatus includes a galvanizing tank, a support frame above the galvanizing tank, and all the aforementioned metal lifting devices below the support frame. An electric actuator is fixedly installed below the support frame, and a mounting base is fixed to the output shaft of the electric actuator by bolts. Multiple guide rods can be alternately immersed in the galvanizing liquid in the galvanizing tank, and both the first sealing ring and the second sealing ring can abut against the circumferential surface of the guide rod to form a seal.

[0014] This utility model provides a metal lifting tool and a hot-dip galvanizing processing device. It has the following beneficial effects: 1. This metal lifting device and hot-dip galvanizing processing apparatus utilizes a rotating base to rotate, which drives multiple guide rods to move synchronously in a circular motion. The workpiece (round tube) is placed on the concave surface of the hook body. Under gravity, the hook body remains vertically downward. The rotating body maintains its vertical position by rotating around the guide rods, thus enabling the hook body to stably lift the round tube without interference from the rotation of the rotating base. By allowing multiple guide rods to alternately immerse in the plating solution, the stability of workpiece lifting is improved, resulting in high production efficiency. Two sealing end caps at both ends of the rotating body reduce the probability of galvanizing solution entering the gap between the rotating body and the guide rods and causing jamming. Multiple protrusions form a splash-proof surface. When the tube is removed from the plating solution, the plating solution inside the tube flows from the port towards the two rotating bases. The splash-proof surface of the rotating base disperses the plating solution flowing out of the tube, preventing high-temperature plating solution from splashing and improving safety.

[0015] 2. In this metal lifting device and hot-dip galvanizing process, both the first and second sealing rings are made of fluororubber to prevent corrosion and withstand high temperatures. Furthermore, the guide rod, rotating body, and hook body are made of Inconel alloy to prevent corrosion and achieve high temperature resistance. The concave surface of the hook body is laser-coated with tungsten carbide particles to improve roughness and thus enhance the anti-slip effect. The first sealing ring is squeezed by the sealing end cap to form a first sealing barrier at the end of the rotating body. The first sealing ring forms a second sealing barrier on the inner wall of the rotating body. Since the two ends of the rotating body are equipped with the same first and second sealing rings, the inner wall of the rotating body is coated with high-temperature resistant long-lasting grease between the two first sealing rings, which can ensure the stability of the rotating body rotating around the guide rod and improve the anti-interference strength of the hook body during the lifting of the workpiece.

[0018] A metal lifting device and a hot-dip galvanizing processing apparatus, such as Figure 1 and Figure 2 As shown, it includes: Two symmetrically distributed mounting bases 10 are provided, each mounting base 10 having a rotating base 11 rotatably mounted on it. Several guide rods 13 are fixedly arranged between the two rotating bases 11. Several protrusions 12 are also fixedly installed at the ends of the rotating bases 11. The rotating bases 11 form a splash-proof surface through the protrusions 12. The protrusions 12 are trapezoidal blocks. By setting multiple protrusions 12 to form a splash-proof surface, when the tube is separated from the plating solution, the plating solution inside the tube will flow from the port towards the two rotating bases 11. The splash-proof surface of the rotating bases 11 will disperse the plating solution flowing out of the tube, preventing the high-temperature plating solution from splashing and improving the safety effect.

[0019] like Figure 3 and Figure 4As shown, a suspension structure is installed on the guide rod 13 for suspending the workpiece. The suspension structure includes a rotating body 20, a hook body 21, and a sealing end cap 22. The hook body 21 is fixedly connected to the rotating body 20, and the rotating body 20 is rotatably connected to the guide rod 13. Both ends of the rotating body 20 are provided with sealing end caps 22 for sealing. The sealing end caps 22 are threadedly connected to the rotating body 20. The guide rod 13 is a cylinder, and multiple guide rods 13 are arranged in a ring array at the end of the rotating seat 11. The rotating body 20 is a round tube, and the inner diameter of the rotating body 20 is larger than the diameter of the guide rod 13. The hook body 21 is an arc-shaped rod, and the hook body 21 is integrally formed with the rotating body 20. The hook body 21 is located on the circumferential surface of the rotating body 20. An annular groove is opened at the end of the rotating body 20, and a boss is formed through the annular groove of the rotating body 20. The boss is threaded, and the sealing end cap 22 is threadedly connected to the boss. In this scheme, the rotating seat 11 rotates and drives multiple guide rods 13 to move synchronously in a circular motion with the rotating seat 11. The workpiece (round tube) is placed on the concave surface of the hook body 21. Under the action of gravity, the hook body 21 remains in a vertical downward position. The hook body 21 can be kept vertical by rotating the rotating body 20 around the guide rods 13. Thus, the hook body 21 can stably support the round tube without being disturbed by the rotation of the rotating seat 11. Based on the alternating immersion of multiple guide rods 13 in the plating solution, the stability of supporting the workpiece can be improved. By setting two sealing end caps 22 to seal both ends of the rotating body 20, the probability of zinc plating liquid entering the gap between the rotating body 20 and the guide rods 13 and causing jamming can be reduced.

[0020] like Figure 4 As shown, the suspension structure also includes a first sealing ring 23 and a second sealing ring 24. The second sealing ring 24 is detachably installed on the end of the sealing end cap 22, and the first sealing ring 23 is detachably installed on the inner wall of the rotating body 20. The end of the sealing end cap 22 is provided with a groove, and the second sealing ring 24 is located in the groove. The inner wall of the rotating body 20 is provided with an annular groove, and the first sealing ring 23 is installed in the annular groove. In this design, both the first sealing ring 23 and the second sealing ring 24 are made of fluororubber to avoid corrosion and resist high temperatures. Secondly, the guide rod 13, the rotating body 20, and the hook body 21 are made of Inconel alloy to avoid corrosion and achieve high temperature resistance. The concave surface of the hook body 21 is laser-clad with tungsten carbide particles to improve roughness and thus improve the anti-slip effect. The first sealing ring 23 is squeezed by the sealing end cap 22 to form a first sealing barrier at the end of the rotating body 20. The first sealing ring 23 forms a second sealing barrier on the inner wall of the rotating body 20. Since the two ends of the rotating body 20 are equipped with the same first sealing ring 23 and second sealing ring 24, the inner wall of the rotating body 20 is coated with high-temperature resistant long-lasting grease with a dropping point >500℃ at the position between the two first sealing rings 23. This can ensure the stability of the rotating body 20 rotating around the guide rod 13 and improve the anti-interference strength of the hook body 21 during the lifting of the workpiece.

[0021] like Figure 5 As shown, a hot-dip galvanizing processing apparatus includes a galvanizing tank 30, a support 31 above the galvanizing tank 30, and all the aforementioned metal lifting devices below the support 31. An electric actuator is fixedly installed below the support 31, and a mounting base 10 is fixed to the output shaft of the electric actuator by bolts. Multiple guide rods 13 can be alternately immersed in the galvanizing liquid in the galvanizing tank 30. The first sealing ring 23 and the second sealing ring 24 can both abut against the circumferential surface of the guide rods 13 to form a seal. The mounting base 10 is controlled above the immersion liquid, and one side of the mounting base 10 is fixed. A motor is fixedly installed, and sprockets are fixedly installed on both the motor output shaft and the end of the rotating base 11. The sprockets are engaged with a chain. The motor can drive the rotating base 11 to rotate, so that multiple guide rods 13 are alternately immersed in the zinc plating solution to achieve alternating zinc plating operations on multiple workpieces. By setting the above structure, zinc plating operations on multiple pipes can be achieved, improving production efficiency and ensuring the stability and safety of the zinc plating process. The zinc plating tank 30 needs to be equipped with a matching electric heating system to heat the molten zinc to form the zinc plating solution. Since this is a well-known existing technology, it will not be described in detail here.

[0022] The working principle of this utility model is as follows: A round tube is placed on the concave surface of the hook body 21. The motor is started, connected to a control switch and power supply. The motor drives the rotating seat 11 to rotate. The rotation of the rotating seat 11 causes multiple guide rods 13 to move synchronously in a circular motion. When the workpiece (round tube) is placed on the concave surface of the hook body 21, under the influence of gravity, the hook body 21 remains vertically downward. The rotating body 20 rotates around the guide rods 13, thus maintaining the vertical position of the hook body 21. Therefore, the hook body 21 can stably support the round tube without being disturbed by the rotation of the rotating seat 11, allowing the multiple guide rods 13 to alternately... The device is immersed in a plating solution for zinc plating. Both the first sealing ring 23 and the second sealing ring 24 are made of fluororubber to avoid corrosion and to withstand high temperatures. Furthermore, the guide rod 13, the rotating body 20, and the hook body 21 are made of Inconel alloy to avoid corrosion and to achieve high temperature resistance. The concave surface of the hook body 21 is laser-coated with tungsten carbide particles to improve roughness and thus improve the anti-slip effect. The first sealing ring 23 is squeezed by the sealing end cap 22 to form a first sealing barrier at the end of the rotating body 20. The first sealing ring 23 forms a second sealing barrier on the inner wall of the rotating body 20, ensuring the stability of the rotating body 20 as it rotates around the guide rod 13.
