Description

Technical Field

[0001] This application relates to the field of hot-dip galvanizing, and more specifically, to a hot-dip galvanizing equipment for square and rectangular tubes. Background Technology

[0002] Square and rectangular tubes are a type of steel pipe with square and rectangular sides, that is, steel pipes with equal or unequal side lengths. They are made from strip steel through a process of rolling. Generally, the strip steel is unpacked, flattened, rolled, and welded to form a round tube, which is then rolled into a square tube and cut to the required length. Nowadays, square and rectangular tubes also need to undergo hot-dip galvanizing after production.

[0003] CN215668164U discloses a hot-dip galvanizing device for square and rectangular tubes. The device involves fitting the left end of the square and rectangular tube onto the outer surface of a left-side insertion plate, pushing the right-side insertion plate to the right to flatten the tube, and then inserting the right-side insertion plate into the right end of the tube via a sliding plate under the action of a corresponding spring. The tube is then moved upward by a suction cup, connecting plate, mounting plate, and snap-fit ​​assembly. A dual-axis motor moves the platform forward to above the hot-dip galvanizing tank, and then an electric push rod is activated to immerse the square and rectangular tube into the molten zinc for hot-dip galvanizing.

[0004] However, the above solution has some drawbacks: the above device clamps the rectangular tube with two plug-in plates, which requires first connecting the left end of the rectangular tube to the left plug-in plate, and then connecting the right end of the rectangular tube to the right plug-in plate. The operation process is cumbersome, labor-intensive, and inefficient. In addition, the fixed-size plug-in plates are not convenient for stably fixing rectangular tubes of different specifications, which has great limitations. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a hot-dip galvanizing equipment for square and rectangular tubes, which aims to improve the problems mentioned in the background art.

[0006] This application provides a hot-dip galvanizing equipment for square and rectangular tubes, including a support assembly and a hot-dip galvanizing assembly.

[0007] The support assembly includes a base plate, a support frame, and an electric slide rail. The support frame is disposed on top of the base plate, and the electric slide rail is disposed on top of the support frame.

[0008] The hot-dip galvanizing assembly includes a hot-dip galvanizing tank, a connecting plate, an electric push rod, a lifting plate, a driving component, a moving plate, a plug-in plate, and a placement rack. The hot-dip galvanizing tank is located on the top of the base plate. The connecting plate is located on one side of the electric slide rail. The electric push rod is fixedly inserted through the connecting plate. The lifting plate is fixedly connected to the movable end of the electric push rod. The driving component is located on one side of the lifting plate. The moving plate is connected to the driving component. The plug-in plate is fixedly connected to the moving plate.

[0009] In one specific implementation, the driving component includes a bidirectional lead screw and a motor. The bidirectional lead screw is rotatably mounted on the top of the lifting plate, and the motor is mounted on the top of the lifting plate and driven by the bidirectional lead screw. The bidirectional lead screw is symmetrically threaded onto two of the moving plates.

[0010] In the above implementation process, by setting up a bidirectional lead screw and a motor, starting the motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two moving plates to move synchronously through the thread transmission principle, and the two moving plates move closer or further away from the square and rectangular tube synchronously.

[0011] In one specific implementation, the lifting plate has an elongated hole, the movable plate slides through the elongated hole, and the movable plate and the inner wall of the elongated hole are fitted with a clearance.

[0012] In the above implementation process, an elongated hole is made to restrict the movement of the guide plate, so that it moves stably in a straight line along the elongated hole.

[0013] In one specific implementation, multiple plug-in plates are spaced apart, and the plug-in plates are conical.

[0014] In the above implementation process, by setting a tapered plug plate, it is possible to insert square and rectangular tubes of different diameters.

[0015] In one specific implementation, the placement rack includes uprights and placement plates, the uprights being fixedly connected to the base plate, the placement plates being fixedly connected to the uprights, and multiple placement plates being spaced apart.

[0016] In the above implementation process, by setting up uprights and placement plates, multiple placement plates are set at intervals to place multiple rectangular tubes at intervals, so that the interlocking plates arranged at intervals can all be inserted into the corresponding rectangular tube openings.

[0017] In one specific implementation, a C-shaped plate is provided on the top of the lifting plate, and the C-shaped plate is fixedly connected to the movable end of the electric push rod.

[0018] In the above implementation process, a C-shaped plate is set to stably connect the movable end of the electric push rod and the lifting plate.

[0019] In one specific implementation, two support frames are provided, one of which has a guide rod at its top, and one end of the connecting plate is slidably sleeved on the guide rod.

[0020] In the above implementation process, a guide rod is set to cooperate with the electric slide rail to stably drive the connecting plate to move horizontally.

[0021] In one specific implementation, a limiting block is provided on the top of the base plate, and the limiting block abuts against the hot-dip galvanizing bath.

[0022] Beneficial effects: This application provides a hot-dip galvanizing equipment for square and rectangular tubes. By setting up a base plate, support frame, electric slide rail, hot-dip galvanizing tank, connecting plate, electric push rod, lifting plate, drive component, moving plate, plug-in plate and placement rack, square and rectangular tubes can be placed on the placement rack. Then, two moving plates move synchronously to drive the plug-in plate to be inserted into the opening of the square and rectangular tube. Finally, it is moved into the hot-dip galvanizing tank for galvanizing. This greatly reduces the intensity of manual labor, and the operation is simple, stable and efficient. At the same time, it can clamp, feed and galvanize square and rectangular tubes of various specifications and sizes, which greatly improves its practicality. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figures 1-4 This application provides a hot-dip galvanizing equipment for square and rectangular tubes, including a support assembly 100 and a hot-dip galvanizing assembly 200.

[0031] Please see Figure 1 and 2 The support assembly 100 includes a base plate 110, a support frame 120, and an electric slide rail 130. The support frame 120 is located on the top of the base plate 110, and the electric slide rail 130 is located on the top of the support frame 120.

[0032] The support frame 120 has two parts. One support frame 120 has a guide rod 121 on its top. One end of the connecting plate 220 is slidably sleeved on the guide rod 121. The guide rod 121 is used to cooperate with the electric slide rail 130 to stably drive the connecting plate 220 to move horizontally.

[0033] In one specific implementation, a limiting block 111 is provided on the top of the base plate 110, and the limiting block 111 abuts against the hot-dip galvanizing bath 210.

[0034] Please see Figure 1 , 2 3 and 4, the hot-dip galvanizing assembly 200 includes a hot-dip galvanizing tank 210, a connecting plate 220, an electric push rod 240, a lifting plate 250, a driving component 260, a moving plate 270, a plug-in plate 280, and a placement rack 290. The hot-dip galvanizing tank 210 is located on the top of the base plate 110. The connecting plate 220 is located on one side of the electric slide rail 130. The electric push rod 240 is fixedly inserted through the connecting plate 220. The lifting plate 250 is fixedly connected to the movable end of the electric push rod 240. The driving component 260 is located on one side of the lifting plate 250. The moving plate 270 is connected to the driving component 260. The plug-in plate 280 is fixedly connected to the moving plate 270. The placement rack 290 is located on the top of the base plate 110.

[0035] The driving component 260 includes a bidirectional lead screw 261 and a motor 262. The bidirectional lead screw 261 is rotatably mounted on the top of the lifting plate 250. The motor 262 is mounted on the top of the lifting plate 250 and is connected to the bidirectional lead screw 261 for transmission. The bidirectional lead screw 261 is symmetrically threaded with two moving plates 270. By setting up the bidirectional lead screw 261 and the motor 262, starting the motor 262 drives the bidirectional lead screw 261 to rotate. The bidirectional lead screw 261 drives the two moving plates 270 to move synchronously through the thread transmission principle. The two moving plates 270 move closer to or further away from the rectangular tube synchronously.

[0036] Specifically, the lifting plate 250 has an elongated hole 251, and the moving plate 270 slides through the elongated hole 251. The moving plate 270 and the inner wall of the elongated hole 251 are fitted with a clearance. The elongated hole 251 is used to restrict the movement of the guide moving plate 270, so that it moves stably and linearly along the elongated hole 251.

[0037] It should be noted that multiple plug-in plates 280 are spaced apart, and the plug-in plates 280 are tapered. By setting the tapered plug-in plates 280, it is possible to insert square and rectangular tubes of different diameters.

[0038] In one specific implementation, the placement rack 290 includes uprights 291 and placement plates 292. The uprights 291 are fixedly connected to the base plate 110, and the placement plates 292 are fixedly connected to the uprights 291. Multiple placement plates 292 are spaced apart. By setting up the uprights 291 and the placement plates 292, and the multiple placement plates 292 spaced apart, multiple rectangular tubes are placed at intervals. This allows the interlocking plates 280 arranged at intervals to be inserted into the corresponding rectangular tube openings. Moreover, while galvanizing, workers can place the rectangular tubes to be galvanized onto empty placement plates 292, saving time and improving efficiency.

[0039] In this embodiment, a C-shaped plate 252 is provided on the top of the lifting plate 250. The C-shaped plate 252 is fixedly connected to the movable end of the electric push rod 240. By providing the C-shaped plate 252, the movable end of the electric push rod 240 and the lifting plate 250 are stably connected.

[0040] The working principle of this hot-dip galvanizing equipment for square and rectangular tubes is as follows: First, place each square and rectangular tube onto the placement plate 292. Then, start the electric slide rail 130. The electric slide rail 130 drives the connecting plate 220, electric push rod 240, lifting plate 250, driving component 260, moving plate 270, and plug-in plate 280 to move. The moving plate 270 and plug-in plate 280 move to both sides of the placement plate 292. Then, start the motor 262 to drive the bidirectional lead screw 261 to rotate. The bidirectional lead screw 261 drives the two moving plates 270 to move synchronously through the threaded transmission principle. The two moving plates 270 drive the conical insertion plate 280 to insert into the square and rectangular tube, thereby clamping the square and rectangular tube. Then, the electric slide rail 130 is controlled to reverse first, moving the square and rectangular tube onto the hot-dip galvanizing tank 210. Then, the electric push rod 240 is activated to extend and place the square and rectangular tube into the hot-dip galvanizing tank 210. This greatly reduces the intensity of manual labor, and the operation is simple, stable and efficient. At the same time, the conical insertion plate 280 and the way the square and rectangular tubes are clamped at both ends can clamp and galvanize square and rectangular tubes of various specifications and sizes, which greatly improves practicality.

[0041] It should be noted that the specific models and specifications of the electric slide rail 130, hot-dip galvanized pool 210, electric push rod 240 and motor 262 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and operating principle of the electric slide rail 130, hot-dip galvanized pool 210, electric push rod 240 and motor 262 are clear to those skilled in the art and will not be described in detail here.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
