Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing hangers, in particular to a porous hanger for hot-dip galvanizing. Background Art

[0002] Hot-dip galvanizing is the most basic, economical and effective method for anti-corrosion of steel materials. It involves lifting and lowering the rust-removed steel parts into molten zinc at about 500°C, so that a zinc layer adheres to the surface of the steel components, thereby achieving the purpose of anti-corrosion.

[0003] The porous hanger for hot-dip galvanizing is an auxiliary equipment used in the hot-dip galvanizing process. It is mainly used to hang and support the workpiece to be galvanized so that it can be immersed in molten zinc for galvanizing. Usually, a hammock is fixed at the bottom of the lifting device, and then the hanger is installed at the bottom of the hammock. The steel piece is connected to the hanger. The lifting device provides power to lift and drive the hanger to perform hot-dip galvanizing on the steel piece.

[0004] Existing hangers have through holes on them. When installing steel parts, the chains are connected by steel wires, and the other end of the chain is connected to the through holes by steel wires. However, this method of connecting the hanger and the chain by binding the steel wires requires manual binding of the steel wires, which makes the installation process of the steel parts time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the existing porous hanger for hot-dip galvanizing is connected to the hanger and the chain by means of steel wire bundling, which is time-consuming and labor-intensive. The present application provides a porous hanger for hot-dip galvanizing.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A porous hanger for hot-dip galvanizing comprises a hanger, wherein the hanger is provided with a through hole, a hook is arranged in the through hole, a tail hole is provided in the hanger, a chain is arranged in the tail hole, and a limiting structure is arranged on the hanger.

[0008] By adopting the above technical solution, when the device is used to perform hot-dip galvanizing on steel parts, the hanger is first hung on the hook with the through hole, and then the chain is inserted into the hanger through the limiting structure, so that the end of the chain is stuck on the hanger, and the middle of the chain is opened in the tail hole. The chain is limited by the limiting structure, so that when the device is used to perform hot-dip galvanizing on steel parts, the installation of the steel parts is more convenient, thereby improving the efficiency of the hot-dip galvanizing process.

[0009] Furthermore, the limiting structure includes a head hole opened on the hanger, the head hole is a semicircular hole, and the head hole is adapted to the chain.

[0010] By adopting the above technical solution, the first ring at the end of the chain is placed horizontally and inserted into the head hole, and then the second ring is slid along the tail hole, so that the first ring and the tail hole are in conflict at 90 degrees, which facilitates the limitation between the chain and the hanger.

[0011] Furthermore, a fixing column is fixedly connected to the hanger, a limiting plate is rotatably connected to the fixing column, a limiting groove is provided on the limiting plate, and the limiting groove is matched with the tail hole.

[0012] By adopting the above technical solution, the chain and the hanger are clamped by the limiting plate, and the limiting groove strengthens the limiting effect of the limiting pad on the chain.

[0013] Furthermore, a torsion spring is sleeved on the fixing column, and two ends of the torsion spring are respectively fixedly connected to the limiting plate and the hanging device.

[0014] By adopting the above technical solution, the torsion spring reset drives the limit plate to rotate toward the chain, thereby strengthening the limiting effect of the limit pad on the chain.

[0015] Furthermore, a limiting pad is fixedly connected to the limiting plate, and a semicircular groove is formed on the limiting pad, and the semicircular groove is adapted to the chain.

[0016] By adopting the above technical solution, the positions of the first ring and the second ring at the end of the chain are limited by the semicircular groove on the limiting pad, thereby improving the stability of the chain.

[0017] Furthermore, a limiting hole is provided on the hanger, a fixing block is slidably arranged in the limiting hole, a supporting bar is fixedly connected to the fixing block, a fixing ring is fixedly connected to the end of the supporting bar, the fixing ring is adapted to the hook, the fixing ring is a semicircular ring, and adjacent fixing rings are fixedly connected by bolts.

[0018] By adopting the above technical solution, the fixing rings are placed on both sides of the hook, and the fixing rings on both sides are fixed by bolts, so that the fixation between the hanger and the hook is more stable.

[0019] Furthermore, a sliding block is slidably connected to the fixed block, a semicircular limiting block is fixedly connected to the end of the sliding block, the semicircular limiting block is adapted to the limiting hole, and a sliding column is slidably connected between adjacent semicircular limiting blocks.

[0020] By adopting the above technical solution, the semicircular limit block is inserted into the limit hole, so that the sliding block moves toward each other along the sliding column. As the semicircular limit block is inserted, when the fixed block fits the surface of the hanger, the semicircular limit block also comes out of the limit hole to limit the hanger.

[0021] Furthermore, a spring is sleeved on the sliding column, and two ends of the spring are respectively fixedly connected to two adjacent semicircular limit blocks.

[0022] By adopting the above technical solution, the spring reset pushes the semicircular limit block to move in the opposite direction along the sliding column, so that it limits the position between the fixed block and the hanger.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the chain is installed on the device, the limit plate is first rotated along the fixed column away from the hanger, and then the first ring at the end of the chain is placed horizontally and inserted from the head hole, and then the second ring is slid along the tail hole, so that the first ring and the tail hole are in conflict with each other at ninety degrees. At this time, the limit plate is loosened to allow the torsion spring to reset and drive the limit plate to rotate, and the chain is rotated toward this. The chain and the hanger are clamped by the limit pad, making it easier to install the chain during use, thereby reducing the time for installing rigid parts, making the device more time-saving and labor-saving when processing steel parts, and improving processing efficiency.

[0025] 2. In the present application, when the hanger is hung on the hook, the semicircular limit block is first inserted into the limit hole, so that the sliding block moves toward each other along the sliding column. As the semicircular limit block is inserted, when the fixed block fits the surface of the hanger, the semicircular limit block also comes out of the limit hole. At this time, the spring reset pushes the semicircular limit block to move in the opposite direction along the sliding column, so that it limits the position between the fixed block and the hanger, and then the fixing ring is placed on both sides of the hook, and the fixing rings on both sides are fixed by bolts, so that the fixation between the hanger and the hook is more stable, which facilitates the stability of the steel parts during the lifting process and improves the processing effect of the device.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a porous hanger for hot-dip galvanizing.

[0035] Reference Figure 1 A porous hanger for hot-dip galvanizing includes a hanger 1, a through hole 3 is opened on the hanger 1, a hook 2 is arranged in the through hole 3, a tail hole 5 is opened on the hanger 1, a chain 6 is arranged in the tail hole, and a limited position structure is arranged on the hanger 1.

[0036] When the device is used to perform hot-dip galvanizing on steel parts, the hanger 1 and the through hole 3 are first hung on the hook 2, and then the chain 6 is inserted into the hanger 1 through the limiting structure, so that the end of the chain 6 is stuck on the hanger 1, and the middle of the chain 6 is opened in the tail hole 5. The chain 6 is limited by the limiting structure, so that when the device is used to perform hot-dip galvanizing on steel parts, the installation of the steel parts is more convenient, thereby improving the efficiency of the hot-dip galvanizing process.

[0037] Reference Figure 2 and Figure 3 , Figure 4 The limiting structure includes a head hole 4 provided on the hanger 1, the head hole 4 is a semicircular hole, and the head hole 4 is adapted to the chain 6. A fixing column 12 is fixedly connected to the hanger 1, and a limiting plate 10 is rotatably connected to the fixing column 12, and a limiting groove is provided on the limiting plate 10, and the limiting groove is adapted to the tail hole 5. A torsion spring 13 is sleeved on the fixing column 12, and the two ends of the torsion spring 13 are fixedly connected to the limiting plate 10 and the hanger 1 respectively. A limiting pad 11 is fixedly connected to the limiting plate 10, and a semicircular groove is provided on the limiting pad 11, and the semicircular groove is adapted to the chain 6.

[0038] When the chain 6 is installed on the device, first rotate the limit plate 10 along the fixing column 12 away from the hanger 1, then place the first ring at the end of the chain 6 horizontally and insert it from the head hole 4, and then slide the second ring along the tail hole 5, so that the first ring and the tail hole 5 are in conflict with each other at ninety degrees. At this time, loosen the limit plate 10 to reset the torsion spring 13 and drive the limit plate 10 to rotate toward the chain 6, and clamp the chain 6 and the hanger 1 through the limit pad 11, so that the device can install the chain 6 more conveniently during use, thereby reducing the time for installing rigid parts, making the device more time-saving and labor-saving when processing steel parts, and improving processing efficiency.

[0039] Reference Figure 3 and Figure 5 A limit hole 18 is provided on the hanger 1, and a fixed block 7 is slidably arranged in the limit hole 18. A support bar 8 is fixedly connected to the fixed block 7, and a fixed ring 9 is fixedly connected to the end of the support bar 8. The fixed ring 9 is adapted to the hook 2, and the fixed ring 9 is a semicircular ring. Adjacent fixed rings 9 are fixedly connected by bolts.

As the semicircular limit block 15 is inserted, when the fixed block 7 fits the surface of the hanger 1, the semicircular limit block 15 also comes out of the limit hole 18. At this time, the spring 17 resets and pushes the semicircular limit block 15 to move in the opposite direction along the sliding column 16, so that it limits the position between the fixed block 7 and the hanger 1, and then the fixing ring 9 is placed on both sides of the hook 2, and the fixing rings 9 on both sides are fixed by bolts, so that the fixation between the hanger 1 and the hook 2 is more stable, which facilitates the stability of the steel parts during the lifting process and improves the processing effect of the device.

[0041] Working principle: When the hanger 1 is hung on the hook 2, the semicircular limit block 15 is first inserted into the limit hole 18, so that the sliding block 14 moves toward each other along the sliding column 16. With the insertion of the semicircular limit block 15, when the fixed block 7 fits the surface of the hanger 1, the semicircular limit block 15 also comes out of the limit hole 18. At this time, the spring 17 resets and pushes the semicircular limit block 15 to move in the opposite direction along the sliding column 16, so that it limits the position between the fixed block 7 and the hanger 1, and then the fixing ring 9 is placed on both sides of the hook 2, and the fixing rings 9 on both sides are fixed by bolts, so that the fixation between the hanger 1 and the hook 2 is more stable, which facilitates the stability of the steel parts during the lifting process and improves the processing effect of the device;

[0042] When the chain 6 is installed on the device, first rotate the limit plate 10 along the fixing column 12 away from the hanger 1, then place the first ring at the end of the chain 6 horizontally and insert it from the head hole 4, and then slide the second ring along the tail hole 5, so that the first ring and the tail hole 5 are in conflict with each other at ninety degrees. At this time, loosen the limit plate 10 to reset the torsion spring 13 and drive the limit plate 10 to rotate toward the chain 6, and clamp the chain 6 and the hanger 1 through the limit pad 11, so that the device can install the chain 6 more conveniently during use, thereby reducing the time for installing rigid parts, making the device more time-saving and labor-saving when processing steel parts, and improving processing efficiency.
