Abstract
Description
Technical Field
[0001] This utility model relates to the field of galvanized steel pipe processing technology, and in particular to a mechanism for suppressing inertia during hot-dip galvanizing of steel pipes. Background Technology
[0002] In the production process of hot-dip galvanized steel pipe, the galvanized steel pipe is lifted out of the zinc pot by the lifting hook and drawn out by the magnetic roller. Then, the galvanized steel pipe is guided to the transverse moving station by the guide roller. When the galvanized steel pipe reaches the transverse moving station, it hits the impact plate and the transverse moving device moves the galvanized steel pipe from the guide moving station to the internal blowing station.
[0003] At this point, a small amount of molten zinc still remains inside the galvanized steel pipe. During the drawing process, the relative velocity between the galvanized steel pipe and the molten zinc inside is zero. When it hits the impact plate, the galvanized steel pipe stops moving, while the molten zinc inside continues to move forward due to inertia. At this time, the molten zinc remaining near the pipe opening will surge onto the surface of the galvanized steel pipe. After this part of the molten zinc cools, the surface becomes rough, affecting the appearance quality of the galvanized steel pipe. This situation is called "tailing phenomenon". To prevent the tailing phenomenon, baffles and spring buffers are usually used to decelerate the moving galvanized steel pipe until the speed drops to zero. This avoids the galvanized steel pipe hitting the impact plate with a certain speed when it reaches the transverse station, thus preventing the tailing phenomenon and ensuring the quality of the galvanized steel pipe. However, the baffles and spring buffers that are in contact with the steel pipe will still have some contact with the galvanized steel pipe, which can easily damage the coating on the surface of the galvanized steel pipe and affect the quality of the finished product.
[0004] Therefore, to address the above issues, a hot-dip galvanizing inertia suppression mechanism can be designed. This mechanism can drive the moving galvanized steel pipe to decelerate until its speed drops to zero without contact. This prevents the galvanized steel pipe from impacting the impact plate with a certain speed when it reaches the lateral movement station, thus avoiding tailing. At the same time, it avoids contact with the galvanized steel pipe, which could damage its surface coating and affect the quality of the finished product. Utility Model Content
[0005] To overcome the current method of using baffles and spring buffers to decelerate the moving galvanized steel pipe until its speed drops to zero, thus preventing the galvanized steel pipe from impacting the collision plate with a certain speed when it reaches the transverse station and causing a tailing phenomenon, and ensuring the quality of the galvanized steel pipe, the current method uses baffles and spring buffers to decelerate the moving galvanized steel pipe until its speed drops to zero. However, the baffles and spring buffers that are in contact with the steel pipe will still have some contact with the galvanized steel pipe, which can easily damage the coating on the surface of the galvanized steel pipe and affect the quality of the finished product.
[0006] The technical solution of this utility model is as follows: a hot-dip galvanized steel pipe inertia suppression mechanism, including a base, a moving platform, an installation component, a sensing component, and a support component. The moving platform is located above the base, the installation component is located above the moving platform, the sensing component is located on one side of the base, the support component is located at the lower end of the base, an air pump is fixedly installed at the upper end of the moving platform, a diversion pipe is provided on one side of the installation component, and multiple sets of air nozzles are connected through one side of the diversion pipe. The multiple sets of air nozzles are arranged in a matrix, and a conveying pipe is connected through the output end of the air pump. The conveying pipe is connected through the diversion pipe.
[0007] Preferably, a support assembly is used to support the base, and an installation assembly is used to support and install the diversion pipe above the moving platform. This allows the diversion pipe to move above the base along with the moving platform, thus following the galvanized steel pipe. An air pump provides high-pressure gas to the diversion pipe through a delivery pipe, and the gas is then diverted and delivered to various nozzles. The ejected gas decelerates the moving galvanized steel pipe until its speed drops to zero, preventing the galvanized steel pipe from impacting the collision plate and causing a tailing phenomenon when it reaches the lateral movement station. The airflow buffers and decelerates the steel pipe, preventing direct contact with the steel pipe and avoiding damage to the coating on the galvanized steel pipe surface, which would affect the quality of the finished product. A sensing assembly is used to monitor the movement of the galvanized steel pipe.
[0008] Preferably, the upper end of the base is provided with a sliding groove, and the moving platform is slidably connected to the base through the sliding groove. A lead screw is rotatably connected inside the sliding groove, and the lead screw passes through the moving platform and is threadedly connected to it. The geared motor is fixedly installed at one end of the base, and the output end of the geared motor is fixedly connected to the lead screw.
[0009] Preferably, multiple sets of connecting frames are fixedly installed at the lower end of the mobile platform, and auxiliary wheels are rotatably connected inside the connecting frames.
[0010] Preferably, the mounting components include an extension plate and reinforcing ribs. The extension plate is fixedly installed on the upper end of the mobile platform, the diversion pipe is fixedly installed on one side of the extension plate, and two sets of reinforcing ribs are fixedly installed at the connection between the extension plate and the mobile platform.
[0011] Preferably, the sensing component includes a mounting plate and a sensor, with the mounting plate fixedly mounted on one side of the base and the sensor fixedly mounted on the upper end of the mounting plate.
[0012] Preferably, multiple sets of mounting plates are provided, and the multiple sets of mounting plates are evenly and linearly arranged on one side of the base.
[0013] Preferably, the support assembly includes an internally threaded sleeve and a threaded support leg. Multiple sets of internally threaded sleeves are fixedly installed at the lower end of the base, and the threaded support leg is threadedly connected to the inside of the internally threaded sleeve.
[0014] The beneficial effects of this utility model are:
[0015] When the galvanized steel pipe moves to one side of the diversion pipe, a high-pressure gas is supplied to the diversion pipe via an air pump through a delivery pipe. The gas is then distributed to various nozzles through the diversion pipe and sprayed out. The gas applies a thrust to the moving galvanized steel pipe, causing it to slowly decelerate until its speed reaches zero. The sprayed gas also prevents the molten zinc inside the steel pipe from overflowing from the pipe opening. Simultaneously, a geared motor drives a lead screw to rotate, thereby moving the moving platform along the slide. Sensors monitor the movement of the galvanized steel pipe, ensuring that the diversion pipe always maintains a distance from the galvanized steel pipe and does not come into contact with it until the galvanized steel pipe comes to a complete stop. The airflow buffers and decelerates the steel pipe, preventing direct contact and avoiding damage to the coating on the surface of the galvanized steel pipe. Attached Figure Description

An air pump 201 is fixedly installed at the upper end of the moving platform 2. A diversion pipe 203 is provided on one side of the installation component, and multiple sets of air nozzles 204 are connected through one side of the diversion pipe 203. The multiple sets of air nozzles 204 are arranged in a matrix. The output end of the air pump 201 is connected through a conveying pipe 202, and the conveying pipe 202 is connected through the diversion pipe 203. The base 1 is supported by the support component, and the diversion pipe is connected through the installation component. The guide pipe 203 is supported and installed above the mobile platform 2, so that the diversion pipe 203 can move above the base 1 with the mobile platform 2, thereby following the galvanized steel pipe. By setting up an air pump 201, high-pressure gas can be provided to the diversion pipe 203 through the delivery pipe 202, and the gas is diverted and delivered to each jet nozzle 204 through the diversion pipe 203. The ejected gas will drive the moving galvanized steel pipe to decelerate until the speed drops to zero, so as to avoid the galvanized steel pipe hitting the collision plate with a certain speed when it reaches the transverse station and causing a tail swing phenomenon. The airflow buffers and decelerates the steel pipe to prevent direct contact with the steel pipe and avoid damage to the coating on the surface of the galvanized steel pipe, which would affect the quality of the finished product. The movement of the galvanized steel pipe can be sensed and monitored by setting up a sensing component.
[0023] Please see Figure 1 and Figure 4 In this embodiment, a sliding groove 101 is provided at the upper end of the base 1. The moving platform 2 is slidably connected to the base 1 through the sliding groove 101. A lead screw 103 is rotatably connected inside the sliding groove 101. The lead screw 103 passes through the moving platform 2 and is threadedly connected to it. A reduction motor 102 is fixedly installed at one end of the base 1, and the output end of the reduction motor 102 is fixedly connected to the lead screw 103. By setting the reduction motor 102 to drive the lead screw 103 to rotate, the moving platform 2 is driven to slide along the sliding groove 101. Multiple sets of connecting frames 301 are fixedly installed at the lower end of the moving platform 2. An auxiliary wheel 302 is rotatably connected inside the connecting frame 301. The connecting frame 301 supports and installs the auxiliary wheel 302. By setting the auxiliary wheel 302, it can provide additional support for the moving platform 2 when it moves, making its movement more stable. The mounting components include an extension plate 401 and a reinforcing rib 402. The extension plate 401 is fixedly installed at the upper end of the moving platform 2, and the diversion pipe 203 is fixedly installed on one side of the extension plate 401. Two sets of reinforcing ribs 402 are fixedly installed at the connection between the extension plate 401 and the moving platform 2. The extension plate 401 supports and installs the diversion pipe 203, and the reinforcing ribs 402 can improve the structural strength of the extension plate 401.
[0024] Please see Figure 2 and Figure 3 In this embodiment, the sensing component includes a mounting plate 501 and a sensor 502. The mounting plate 501 is fixedly installed on one side of the base 1, and the sensor 502 is fixedly installed on the upper end of the mounting plate 501. Multiple sets of mounting plates 501 are arranged linearly and evenly on one side of the base 1. The mounting plates 501 support and install the sensor 502. The multiple linearly arranged sensors 502 can monitor the movement of the galvanized steel pipe, thereby... The operation of the geared motor 102 is controlled so that the moving platform 2 can move along with the galvanized steel pipe; the support assembly includes an internal threaded sleeve 601 and a threaded support leg 602. Multiple sets of internal threaded sleeves 601 are fixedly installed at the lower end of the base 1, and the threaded support leg 602 is threadedly connected to the inside of the internal threaded sleeve 601; the base 1 is supported and installed by setting the threaded support leg 602, and the base 1 can be leveled and adjusted by setting the threaded support leg 602 to rotate inside the internal threaded sleeve 601.
[0025] During operation, the reducer motor 102 drives the lead screw 103 to rotate, causing the moving platform 2 to slide along the slide groove 101 and move to one end of the base 1. When the galvanized steel pipe moves to one side of the diversion pipe 203, the air pump 201 can provide high-pressure gas to the diversion pipe 203 through the delivery pipe 202, and the gas is diverted and delivered to each nozzle 204 through the diversion pipe 203. The gas is used to apply a thrust to the moving galvanized steel pipe, causing it to slowly decelerate until the speed drops to zero. The sprayed gas can also prevent the zinc liquid inside the steel pipe from gushing out of the pipe opening.
[0026] At the same time, the reducer motor 102 drives the lead screw 103 to rotate, thereby driving the moving platform 2 to move along the slide 101. The sensor 502 is used to sense and monitor the movement of the galvanized steel pipe, so that the diversion pipe 203 always maintains a certain distance from the galvanized steel pipe and does not contact it until the galvanized steel pipe comes to a complete stop.
[0027] Through the above steps, the air pump 201 provides high-pressure gas to the diversion pipe 203 via the delivery pipe 202, and the gas is sprayed out through each nozzle 204. The sprayed gas will decelerate the moving galvanized steel pipe until its speed drops to zero, thus preventing the galvanized steel pipe from impacting the impact plate with a certain speed when it reaches the transverse station and causing a tailing phenomenon. The airflow buffers and decelerates the steel pipe, preventing direct contact with the steel pipe and avoiding damage to the coating on the surface of the galvanized steel pipe. This solves the problem that the current method of using baffles and spring buffers to decelerate the moving galvanized steel pipe until its speed drops to zero, and prevents the galvanized steel pipe from impacting the impact plate with a certain speed when it reaches the transverse station and causing a tailing phenomenon, thus ensuring the quality of the galvanized steel pipe. However, the baffles and spring buffers that are in contact with the steel pipe will still have some contact with the galvanized steel pipe, which can easily cause damage to the coating on the surface of the galvanized steel pipe and affect the quality of the finished product.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
