Description

Technical Field

[0001] This patent relates to the field of galvanized pipe processing technology, specifically an adjustable hanger for hot-dip galvanizing. Background Technology

[0002] In the processing of galvanized pipes, steel pipes need to be suspended using a hanger, and then the hanger is moved to allow the steel pipes to enter the hot-dip galvanizing bath for galvanizing. Existing hangers consist of a cylinder-driven hanging plate with two clamps at the bottom for suspending the steel pipes. However, the length of the hanging plate is relatively fixed, and it can only clamp steel pipes of a single length, which cannot meet the suspension needs of steel pipes of different lengths and has a limited scope of application. Therefore, we propose an adjustable hanger for hot-dip galvanizing processing. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide an adjustable hanger for hot-dip galvanizing. This patent features a self-limiting threaded seat controlled by a lead screw motor within a first plate. The bottom of the self-limiting threaded seat is connected to a second plate. Clamping plates are installed on the bottom of both the first and second plates. The lead screw motor can drive the second plate to move left and right, thereby adjusting the distance between the two clamping plates. This facilitates the clamping of steel pipes of different lengths, meeting the clamping requirements of steel pipes of varying lengths to be galvanized, and has a wide range of applications.

[0004] The technical solution adopted by this patent to solve its technical problem is: an adjustable hanger for hot-dip galvanizing, including a drive mechanism, a first plate fixedly installed at the bottom of the drive mechanism, a rectangular hole provided at the top of the first plate, a lead screw motor fixedly installed at the left end of the rectangular hole, a screw fixedly installed at the right end of the shaft of the lead screw motor, a self-limiting threaded seat screwed onto the side wall of the screw, a second plate fixedly installed at the bottom of the self-limiting threaded seat, and clamping plates installed on the bottom left side of the first plate and the bottom right side of the second plate; The second plate has a circular groove at its right end, and the bottom wall of the circular groove has an opening. A spring is fixedly installed on the left inner wall of the circular groove, and a sliding column is fixedly installed on the right end of the spring. The side wall of the sliding column slides against the inner side wall of the circular groove. A T-shaped rod is fixedly installed on the right end of the sliding column, and the top of the clamping plate on the right side is fixed to the bottom of the sliding column.

[0005] Furthermore, the drive mechanism can be a cylinder or an electric actuator.

[0006] Furthermore, the self-limiting threaded seat includes an internal threaded ring, the inner sidewall of which is screwed onto the screw rod, and wheel seats are fixedly installed at both ends of the outer sidewall of the internal threaded ring. A limiting wheel is connected to the wheel seat through a rotating shaft. The inner front and rear sidewalls of the rectangular hole are provided with wheel grooves, and the wheel body edge of the limiting wheel is rolled and installed in the wheel groove.

[0007] Furthermore, the second plate body includes a left plate body and a right plate body, and the circular groove is disposed in the middle of the right plate body.

[0008] Furthermore, the left and right plates are integrally formed with mounting plates and mounting rings on their front and rear sides, respectively. A stud is integrally formed on the right side of the mounting plate, and a nut is screwed onto the right end of the stud through the mounting ring.

[0009] Furthermore, the diameter of the right end of the T-shaped rod is smaller than the diameter of the circular groove.

Detailed Implementation

[0015] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0016] See Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the structure of this patent. An adjustable hanger for hot-dip galvanizing includes a drive mechanism 1. A first plate 2 is fixedly installed at the bottom of the drive mechanism 1. A rectangular hole 3 is provided at the top of the first plate 2. A lead screw motor 4 is fixedly installed at the left end of the rectangular hole 3. A screw 5 is fixedly installed at the right end of the shaft of the lead screw motor 4. A self-limiting threaded seat 6 is screwed onto the side wall of the screw 5. A second plate 7 is fixedly installed at the bottom of the self-limiting threaded seat 6. Clamping plates 8 are installed on the bottom left side of the first plate 2 and the bottom right side of the second plate 7. like Figure 1 As shown, the inner wall of the clamping plate 8 is provided with a post for insertion into the end of the steel pipe.

[0017] The right end of the second plate 7 is provided with a circular groove 9. The bottom wall of the circular groove 9 is provided with an opening. A spring 10 is fixedly installed on the left inner wall of the circular groove 9. A sliding column 11 is fixedly installed on the right end of the spring 10. The side wall of the sliding column 11 slides against the inner side wall of the circular groove 9. A T-shaped rod 12 is fixedly installed on the right end of the sliding column 11. The top of the clamping plate 8 on the right side is fixed to the bottom of the sliding column 11.

[0018] Specifically, the drive mechanism 1 can be a cylinder or an electric actuator.

[0019] The outer cylinder of the cylinder or electric actuator can be fixed above the hot-dip galvanizing bath, and the telescopic rod is fixed to the first plate 2.

[0020] Specifically, the self-limiting threaded seat 6 includes an internal threaded ring 13, the inner sidewall of which is screwed onto the screw rod 5. Wheel seats 14 are fixedly installed at both ends of the outer sidewall of the internal threaded ring 13. A limiting wheel 15 is connected to the wheel seat 14 through a rotating shaft. The inner front and rear sidewalls of the rectangular hole 3 are provided with wheel grooves 16. The wheel body edge of the limiting wheel 15 is rolled and installed in the wheel groove 16.

[0021] In traditional lead screw systems, the limiting structure mostly slides within the guide rail via a slider, resulting in significant friction and wear between components, requiring frequent replacement. However, by rolling the limiting wheel 15 within the wheel groove 16 at the edge of the wheel body, the limiting becomes a rolling limit, which can greatly reduce friction and wear.

[0022] Specifically, the second plate 7 includes a left plate 17 and a right plate 18, with a circular groove 9 located in the middle of the right plate 18.

[0023] By including a left plate 17 and a right plate 18 in the second plate 7, the middle right end of the left plate 17 becomes the inner left side wall of the circular groove 9. Figure 1(Regarding the installation position of the left end of the spring 10), during the initial assembly, the left end of the spring 10 can be fixed to the middle of the right end of the left plate 17. Then, the sliding column 11 and the T-shaped rod 12 are installed in sequence, and the circular groove 9 in the middle of the right plate 18 is fitted onto the outside of the above structure. Subsequently, the left plate 17 and the right plate 18 are fixed by studs and nuts.

[0024] Specifically, mounting plates 19 and mounting rings 20 are integrally formed on the front and rear sides of the left plate 17 and the right plate 18, respectively. A stud is integrally formed on the right side of the mounting plate 19, and a nut is screwed onto the right end of the stud through the mounting ring 20.

[0025] Specifically, the diameter of the right end of the T-shaped rod 12 is smaller than the diameter of the circular groove 9.

[0026] The diameter of the right end of the T-shaped rod 12 is smaller than the diameter of the circular groove 9, which facilitates the right end of the T-shaped rod 12 to pass through the circular groove 9, which is the aforementioned preliminary assembly.

[0027] Working principle: The screw motor 4 drives the screw 5 to rotate, which in turn drives the self-limiting threaded seat 6 and the second plate 7 to move left and right, so as to adjust the distance between the two clamping plates 8 to clamp steel pipes of different lengths. After adjustment, the T-shaped rod 12 is pulled to the right to move the right clamping plate 8 to the right, and the left end of the steel pipe is inserted into the insertion post on the right side of the left clamping plate 8. The right clamping plate 8 is released and the spring 10 rebounds, so that the right clamping plate 8 clamps the right end of the steel pipe. The drive mechanism 1 drives the whole to move downward, so that the steel pipe enters the zinc liquid in the hot-dip galvanizing bath below for galvanizing.

[0028] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.

However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0029] This patent features a self-limiting threaded seat controlled by a lead screw motor within the first plate. The bottom of the self-limiting threaded seat is connected to the second plate. Clamping plates are installed on the bottom of both the first and second plates. The lead screw motor can drive the second plate to move left and right, thereby adjusting the distance between the two clamping plates. This facilitates the clamping of steel pipes of different lengths and can meet the clamping requirements of steel pipes of different lengths to be galvanized, thus having a wide range of applications.
