Description

Technical Field

[0001] This utility model relates to the field of steel structure galvanizing technology, specifically to a steel structure surface galvanizing equipment. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Due to their light weight and simple construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. Galvanizing steel structures requires the use of galvanizing equipment. Galvanizing refers to a surface treatment technology that coats the surface of metals, alloys, or other materials with a layer of zinc for aesthetic purposes, rust prevention, and other functions.

[0003] A search revealed Chinese patent application number CN201921716845.5, which discloses a galvanizing device for steel structure processing. The device includes a galvanizing tank and L-shaped support plates. The L-shaped support plates are symmetrically arranged on the left and right sides of the galvanizing tank, and a support plate is slidably connected between them. A U-shaped hanger is installed inside the galvanizing tank. A rotating ring is sleeved at the bottom of the U-shaped hanger, and a vertical rod is welded and fixed to the upper end of the rotating ring. A support ring and a steel pipe are sleeved on the vertical rod, with the steel pipe located between the support rings. A pull rope is connected to the upper end of the U-shaped hanger, and the other end of the pull rope is connected to the support plate. In this invention, the inner annular side of the support ring is machined with threaded holes. The support ring is connected to the threads on the vertical rod through these threaded holes. Both the upper and lower parts of the support ring have a conical structure, with the conical portions extending into the steel pipe to facilitate clamping the steel pipe and prevent loosening.

[0004] In the process of implementing this utility model, the inventors discovered the following problems with the existing technology:

[0005] During use, the workpieces need to be fixed to the hanger one by one by threaded connection each time. After the steel pipe is galvanized, the steel pipe needs to be disassembled from the hanger. However, the surface of the galvanized steel pipe is covered with molten zinc, which not only makes it inconvenient for workers to disassemble, but also reduces work efficiency.

[0006] Therefore, this invention aims to provide a steel structure surface galvanizing device that can quickly clamp and fix workpieces of different sizes during use, thereby improving work efficiency. After galvanizing, each workpiece in the clamp can be driven to rotate so that it can be thoroughly dried by a drying mechanism, preventing molten zinc from adhering to the surface of the galvanized workpiece. This is a problem that this invention urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the shortcomings of existing technologies that require workpieces to be sequentially fixed to the hanger via threaded connections each time, and the need to disassemble the steel pipe from the hanger after galvanizing. Furthermore, the galvanized steel pipe surface is coated with molten zinc, which not only hinders disassembly but also reduces work efficiency. This invention provides a steel structure surface galvanizing device that uses clamps to quickly clamp and fix workpieces of different sizes during use, improving work efficiency. After galvanizing, each workpiece in the clamp is driven to rotate so that it can be thoroughly dried by a drying mechanism, preventing molten zinc from adhering to the surface of the galvanized workpiece.

[0008] To achieve the above objectives, this utility model provides a steel structure surface galvanizing equipment, the equipment comprising: a galvanizing tank, a support base vertically fixed at the upper opening of the galvanizing tank, a clamp that can be raised and lowered inside the support base and can extend into the galvanizing tank, and a plurality of drying mechanisms disposed on the side wall of the support base for blowing and drying the workpiece on the clamp.

[0009] The clamp includes: a lower clamping plate with several vertically penetrating holes uniformly distributed on its surface, a lower clamping head, an upper clamping plate, and an upper clamping head; wherein...

[0010] The galvanizing bath is equipped with a horizontally movable lower clamping plate inside. Above the lower clamping plate, there is a horizontally movable upper clamping plate that can extend from the opening of the galvanizing bath. The opposing surfaces of the two are vertically and rotatably equipped with a row of lower clamps and a row of upper clamps that correspond to each other and are adapted to clamp and rotate the workpiece. Each lower clamp is composed of multiple frustum columns of different diameters connected end to end. Each lower clamp and the upper clamp have the same structure, and the diameter of each lower clamp facing the workpiece decreases sequentially.

[0011] Preferably, the device further includes a power mechanism for driving a row of workpieces clamped on the fixture to rotate, the power mechanism comprising: a power gear, a power gear plate, and a power cylinder; wherein,

[0012] The rotating shaft ends of each of the row of upper clamps extend to the upper end of the upper clamping plate and are respectively coaxially fixed with power gears. The upper end of the upper clamping plate located next to the row of rotating shafts is horizontally and movably provided with a power gear plate that meshes with the row of power gears via a power cylinder. The power cylinder is horizontally fixed on the upper clamping plate and is arranged parallel to the power gear plate. The free end of its piston rod is fixed on the power gear plate via a connecting plate.

[0013] Preferably, the device further includes a drive mechanism for driving the upper clamping plate to move vertically up and down, the drive mechanism comprising: a lifting cylinder and a vertical plate; wherein,

[0014] On the lower clamping plates located on both sides of the row of lower clamps, there are vertically fixed inverted L-shaped upright plates, and the top of each of the two upright plates is vertically fixed with a lifting cylinder. The free end of the piston rod of each lifting cylinder is fixed on the upper clamping plate. The top of the support base is vertically opened with an opening for the two lifting cylinders to pass through.

[0015] Preferably, guide rods are vertically fixed inside the two upright plates, and guide holes are vertically opened on the upper clamping plate for the two guide rods to pass through. The upper clamping plate is movably mounted on the two guide rods through the two guide holes.

[0016] Preferably, the device further includes a lifting mechanism for driving the clamp to move up and down in the vertical direction, the lifting mechanism comprising: a lifting screw, a lifting slider, and a lifting motor; wherein,

[0017] Inside the support base located on both sides of the two upright plates, lifting screws are vertically and rotatably installed, and each lifting screw is threadedly fixed with a lifting slider. The two upright plates are respectively fixed on the two lifting sliders. The top of each lifting screw extends to the upper end of the support base and is coaxially connected to the lifting motor vertically fixed to the top of the support base via a coupling.

[0018] Preferably, the drying mechanism includes: a fan; wherein,

[0019] The support base has an operating port on one side that communicates with its interior, and at least two fans are fixedly installed on the side wall of the support base opposite the operating port to dry the galvanized workpiece.

[0020] According to the above technical solution, the beneficial effects of the steel structure surface galvanizing equipment provided by this utility model in use are as follows:

[0021] (1) Since each lower chuck and upper chuck is made of multiple truncated cylindrical columns of different diameters spliced ​​together end to end, and the diameter of each lower chuck and each upper chuck facing the workpiece decreases sequentially, the combined use of a row of lower chucks on the lower clamping plate and a row of upper chucks on the upper clamping plate can clamp tubular workpieces of different inner diameters, thereby improving the practicality of the fixture.

[0022] (2) The process of using the fixture is as follows: drive the upper clamping plate to raise the row of upper chucks on it to a suitable position, and then vertically place multiple workpieces onto the row of lower chucks on the lower clamping plate in sequence. Drive the upper clamping plate to descend vertically again until the row of upper chucks on the upper clamping plate is inserted into the end of each workpiece, so as to clamp and fix a row of workpieces between the row of lower chucks and upper chucks between the lower clamping plate and the upper clamping plate. Since the upper chucks and lower chucks are rotatably assembled on the lower clamping plate and the upper clamping plate through a rotating shaft, the workpieces between the lower chucks and upper chucks can be rotated during the rotation of the rotating shaft of the lower chuck or the rotating shaft of the upper chuck. This allows the workpieces on the fixture to be rotated by driving the rotating shaft of the row of upper chucks or lower chucks during the drying process of the drying mechanism. This is beneficial for the drying mechanism to dry the workpieces comprehensively and improve the uniformity and reliability of drying.

[0023] In summary, this invention enables the quick clamping and fixing of workpieces of different sizes using a fixture, thus improving work efficiency. After galvanizing, each workpiece in the fixture can be driven to rotate so that each workpiece can be thoroughly dried by the drying mechanism, preventing molten zinc from adhering to the surface of the galvanized workpiece.

Detailed Implementation

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] like Figure 1-5 As shown, the present invention provides a steel structure surface galvanizing equipment, the equipment comprising: a galvanizing tank 1, a support base 2 vertically fixed at the upper opening of the galvanizing tank 1, a clamp 3 vertically and elliptically disposed in the support base 2 and capable of extending into the galvanizing tank 1, and a plurality of drying mechanisms 4 disposed on the side wall of the support base 2 for blowing and drying the workpiece on the clamp 3.

[0035] The clamp 3 includes: a lower clamping plate 301 with several vertically penetrating holes uniformly distributed on its surface, a lower clamping head 302, an upper clamping plate 303, and an upper clamping head 304; wherein...

[0036] The galvanizing bath 1 is equipped with a horizontally movable lower clamping plate 301. Above the lower clamping plate 301, there is a horizontally movable upper clamping plate 303 that can extend from the opening of the galvanizing bath 1. The opposing surfaces of the two are vertically and rotatably equipped with a row of lower clamps 302 and a row of upper clamps 304 that correspond to and are adapted to clamp and rotate the workpiece. Each lower clamp 302 is composed of multiple frustum columns of different diameters connected end to end. Each lower clamp 302 and upper clamp 304 has the same structure. The diameter of each lower clamp 302 facing the workpiece decreases sequentially.

[0037] In the above scheme, since each of the lower chucks 302 and the upper chucks 304 is formed by sequentially splicing together multiple frustum columns of different diameters, and the diameter of each of the lower chucks 302 and the upper chucks 304 facing the workpiece decreases sequentially, the combined use of a row of lower chucks 302 on the lower clamping plate 301 and a row of upper chucks 304 on the upper clamping plate 303 can clamp tubular workpieces of different inner diameters, thereby improving the practicality of the fixture 3. The surfaces of the upper chuck 302 and the lower chuck 304 are fitted with rubber sleeves that are compatible with them. On the one hand, when the upper chuck 304 and the lower chuck 302 seal the two ends of the workpiece held between them, they prevent the zinc liquid from flowing into the workpiece from both ends during the zinc plating process, thus avoiding unnecessary waste. On the other hand, the rubber sleeves allow the lower chuck 302 and the upper chuck 304 to press tightly against the two ends of the workpiece, increasing the friction between the workpiece and the lower chuck 302 and the upper chuck 304. This improves the reliability and firmness of the upper chuck 304 and the lower chuck 302 in clamping and fixing the workpiece, so that the workpiece between the lower chuck 302 and the upper chuck 304 can be rotated during any rotation of the shaft of the lower chuck 302 or the shaft of the upper chuck 304.

[0038] The clamp 3 is used as follows: The upper clamping plate 303 is driven to raise a row of upper chucks 304 to a suitable position. Multiple workpieces are then vertically placed onto a row of lower chucks 302 on the lower clamping plate 301. The upper clamping plate 303 is then driven to descend vertically until the row of upper chucks 304 on the upper clamping plate 303 is inserted into the end of each workpiece, thus clamping and fixing a row of workpieces between the row of lower chucks 302 and upper chucks 304 between the lower clamping plate 301 and the upper clamping plate 303. Because the upper chucks 304 and the lower chucks... Both heads 302 are rotatably mounted on the lower clamping plate 301 and the upper clamping plate 303 via rotating shafts. Therefore, during the rotation of the rotating shaft of the lower clamping head 302 or the upper clamping head 304, the workpiece between the lower clamping head 302 and the upper clamping head 304 can be rotated. This allows the workpiece to be rotated by driving the rotating shafts of the upper clamping head 304 or the lower clamping head 302, thus facilitating the drying mechanism 4 to thoroughly dry the workpiece and improving the uniformity and reliability of the drying process.

[0039] In use, the galvanizing bath 1 is filled with an appropriate amount of molten zinc, and multiple workpieces are assembled onto the fixture 3, such as... Figure 1-5As shown, the clamp 3 is then driven to lower the workpiece mounted on it into the galvanizing bath 1, completely submerging the workpiece in the zinc liquid for galvanizing. After galvanizing, the clamp 3 is driven to raise the workpiece until the clamp 3 protrudes from the opening of the galvanizing bath 1 and faces the drying mechanism 3. The drying mechanism 3 is then activated to dry the galvanized workpiece. Simultaneously, the shafts of a row of upper chucks 304 or lower chucks 302 are driven to rotate a row of workpieces, thereby facilitating the drying mechanism 4 to thoroughly dry the workpieces and improving the uniformity and reliability of the drying process.

[0040] In a preferred embodiment of this utility model, the device further includes a power mechanism 5 for driving a row of workpieces clamped on the fixture 3 to rotate. The power mechanism 5 includes: a power gear 501, a power gear plate 502, and a power cylinder 503; wherein,

[0041] The rotating shaft ends of each of the upper clamps 304 extend to the upper end of the upper clamping plate 303 and are respectively coaxially fixed with power gears 501. The upper end of the upper clamping plate 303 located next to the row of rotating shafts is horizontally and movably provided with a power gear plate 502 that meshes with the row of power gears 501 via a power cylinder 503. The power cylinder 503 is horizontally fixed on the upper clamping plate 303 and is arranged parallel to the power gear plate 502. The free end of its piston rod is fixed on the power gear plate 502 via a connecting plate.

[0042] In the above scheme, during use, the power gear plate 502 is driven to move horizontally back and forth on the upper clamping plate 303 by driving the piston rod of the power cylinder 503 to extend from or retract into its cylinder. During the back and forth movement, the power gear plate 502 can drive all the power gears 501 that are meshed with it to drive the rotating shaft of a row of upper chucks 304 to rotate, thereby driving a row of workpieces clamped between a row of upper chucks 304 and a row of lower chucks 302 to rotate alternately in two opposite directions, so that the drying mechanism can thoroughly dry the surface of each workpiece.

[0043] In a preferred embodiment of this utility model, the device further includes a drive mechanism for driving the upper clamping plate 303 to move vertically up and down, the drive mechanism comprising: a lifting cylinder 7 and a vertical plate 9; wherein,

[0044] On the lower clamping plates 301 located on both sides of the lower clamping heads 302, there are vertically fixed inverted L-shaped upright plates 9, and the tops of the two upright plates 9 are vertically fixed through and through, respectively. The free end of the piston rod of each of the lifting cylinders 7 is fixed on the upper clamping plate 303. The top of the support base 2 is vertically opened through for the two lifting cylinders 7 to pass through.

[0045] In the above scheme, during use, by activating the lifting cylinder 7 to extend or retract its piston rod from its cylinder, the upper clamping plate 303 can be driven to move the row of upper clamps 304 on it downward and upward in the vertical direction.

[0046] In a preferred embodiment of this utility model, guide rods 8 are vertically fixed inside the two upright plates 9 respectively, and guide holes for the two guide rods 8 to pass through are vertically through the upper clamping plate 303 respectively. The upper clamping plate 303 is movably mounted on the two guide rods 8 through the two guide holes.

[0047] In the above scheme, the two guide holes and two guide rods 8 of the upper clamping plate 303 can be used in combination to ensure that the upper clamping plate 303 can rise and fall smoothly and reliably in a straight line.

[0048] In a preferred embodiment of this utility model, the device further includes a lifting mechanism 6 for driving the clamp 3 to move up and down in the vertical direction. The lifting mechanism 6 includes: a lifting screw 601, a lifting slider 602, and a lifting motor 603; wherein,

[0049] Inside the support bases 2 located on both sides of the two upright plates 9, lifting screws 601 are vertically and rotatably installed, and each lifting screw 601 is threadedly fixed with a lifting slider 602. The two upright plates 9 are respectively fixed on the two lifting sliders 602. The top end of each lifting screw 601 extends to the upper end of the support base 2 and is coaxially connected to the lifting motor 603 vertically fixed to the top end of the support base 2 via a coupling.

[0050] In the above scheme, during use, the two lifting motors 603 are started synchronously to drive the two lifting screws 601 to rotate synchronously. During the rotation of the two motors, the two lifting sliders 603 can be driven synchronously to drive the two vertical plates 9 to drive the clamp 3 to rise and fall in the vertical direction, so that the workpiece on the clamp 3 is lowered and immersed in the zinc liquid in the galvanizing bath 1 for galvanizing operation, or the clamp 3 is raised to leave the zinc liquid and the workpiece on it is extended from the opening of the galvanizing bath 1 and raised to the position facing the drying mechanism 4.

[0051] In a preferred embodiment of this utility model, the drying mechanism 4 includes: a fan; wherein,

[0052] The support base 2 has an operating port on one side that is connected to its interior, and at least two fans are fixedly installed on the side wall of the support base 2 facing the operating port to dry the galvanized workpiece.

[0053] In the above scheme, the side wall of the support 2 facing the operation port is provided with a plurality of ventilation holes for assembling the fan. Each ventilation hole is provided with a fan that can blow air toward the clamp 3. The fan can be a blower fan.

[0054] In use, a fan blows air onto the workpiece on the fixture 3 to dry the galvanized workpiece.

[0055] The fan can be a blower.

[0056] In addition, both the power cylinder 503 and the lifting cylinder 7 are existing and well-known technologies. Therefore, their structures and working principles will not be described in detail here. They can also be replaced by existing servo electric cylinders to achieve the same functions and effects.

[0057] In summary, the steel structure surface galvanizing equipment provided by this utility model overcomes the problems of existing technology, which requires the workpiece to be fixed to the hanger sequentially by means of threaded connection each time, and the steel pipe to be disassembled and separated from the hanger after galvanizing. The surface of the galvanized steel pipe is covered with zinc liquid, which is not only inconvenient for workers to disassemble, but also reduces work efficiency.
