Description

Technical Field

[0001] This utility model relates to the field of pickling machine technology, specifically to a pickling machine used for hot-dip galvanizing of channel steel. Background Technology

[0002] Pickling machines are devices that use acid solutions such as hydrochloric acid and sulfuric acid to remove oxide scale, rust, and oil stains from metal surfaces. They achieve surface purification through immersion, spraying, and other methods, providing a clean substrate for subsequent processing such as plating and welding. Hot-dip galvanizing of channel steel involves immersing the channel steel in molten zinc, forming a zinc alloy coating on its surface. This utilizes the sacrificial anode effect of zinc to achieve corrosion protection and is a commonly used process for steel corrosion prevention.

[0003] Current purification pickling machines require operators to manually move the channel steel to perform different processes, which is time-consuming and labor-intensive. Furthermore, the clamping of the channel steel is not secure, making it easy for the channel steel to slip off. In addition, it is difficult to adapt to channel steel of different specifications, which seriously affects pickling efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to provide a pickling machine for hot-dip galvanizing of channel steel, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pickling machine for hot-dip galvanizing of channel steel, including a support slide rail, a moving mechanism rotatably connected to the inner walls of the left and right sides of the support slide rail, a lifting mechanism screwed to the bottom end of the moving mechanism, a support plate at the bottom end of the lifting mechanism, an adjustment mechanism on both sides of the bottom of the support plate, and a hook at the bottom of the adjustment mechanism.

[0006] Below the support slide rail, from left to right, are arranged an acid pickling tank, a neutralization tank, and a rinsing tank.

[0007] The beneficial effects of this utility model are as follows: the moving mechanism achieves precise positioning of the moving screw seat through a servo motor and a moving screw, ensuring continuous and efficient process; the lifting mechanism is driven by a hydraulic cylinder, with a telescopic rod assisting in smooth lifting, ensuring precise immersion and detachment of the channel steel, reducing collisions; the adjusting mechanism, through a throttle and sprocket drive linked to a bidirectional screw, can flexibly adjust the hook spacing to adapt to channel steels of different lengths, improving versatility; the hooks are securely clamped by compression springs and anti-slip layers to prevent slippage, ensuring process stability and improving safety and quality.

[0008] To ensure precise positioning for continuous pickling processes, a servo motor in the moving mechanism provides stable power to drive the moving screw, enabling the moving screw seat to move accurately along the support slide rail.

[0009] The moving mechanism is further configured such that: the moving mechanism includes a servo motor, the output end of the servo motor is connected to a moving screw, the left and right ends of the moving screw are respectively rotatably connected to the inner walls of the left and right sides of the supporting slide rail, and the outer wall of the moving screw is screwed with a moving screw seat.

[0010] By adopting the above technical solution, the moving mechanism provides stable power through a servo motor, which drives the moving screw to rotate, so that the moving screw seat moves precisely along the support slide rail. This structure can ensure that the channel steel is accurately positioned above the pickling tank, neutralization tank and rinsing tank, providing precise positional assurance for continuous pickling processes and improving the continuity and efficiency of the overall process.

[0011] To ensure stable lifting and lowering of the support plate and channel steel via the piston rod in the hydraulic cylinder of the lifting mechanism, the telescopic rods at the four corners assist in keeping the support plate level, preventing tilting and swaying during lifting, and ensuring that the channel steel can be accurately immersed into each tank.

[0012] The lifting mechanism is further configured such that: the top end of the hydraulic cylinder is screwed to the middle of the bottom of the movable screw seat; a piston rod is provided at the middle of the bottom of the hydraulic cylinder; a support plate is provided at the bottom end of the piston rod; and telescopic rods are provided between the support plate and the four corners of the movable screw seat.

[0013] By adopting the above technical solution, the hydraulic cylinder in the lifting mechanism provides strong and controllable lifting power, the piston rod drives the support plate and channel steel to lift steadily, and the telescopic rods at the four corners help to keep the support plate horizontal and avoid tilting and swaying during lifting. This structure ensures that the channel steel can be accurately immersed into the interior of each tank and can also be smoothly removed, which not only ensures the processing effect, but also reduces the risk of the channel steel colliding with the tank.

[0014] To achieve synchronous rotation of two bidirectional screws via the main drive sprocket, drive chain, and driven sprocket when the throttle is turned using the adjustment mechanism, the hook spacing can be flexibly adjusted to accommodate different specifications of channel steel:

[0015] The adjustment mechanism is further configured as follows: the adjustment mechanism includes two bidirectional screws, the two ends of which are rotatably connected to the bottom sides of the support plate respectively; a main drive sprocket is sleeved on the outer wall of one end of the bidirectional screw, and a driven drive sprocket is sleeved on the outer wall of the other end of the bidirectional screw; a drive chain is meshed on the outer walls of the main drive sprocket and the driven drive sprocket; a throttle is provided at the end of the bidirectional screw sleeved with the main drive sprocket; and movable screw blocks are screwed onto the outer walls of the two bidirectional screws.

[0016] By adopting the above technical solution, the adjustment mechanism drives two bidirectional screws to rotate synchronously via the main drive sprocket, drive chain and driven sprocket when the throttle is turned, so that the moving screw block drives the hook to flexibly adjust the spacing. This design can quickly adapt to channel steel of different lengths and improve the equipment's versatility for channel steel of different specifications.

[0017] To enable the compression spring at the hook to push the clamping plate and tighten the channel steel, the anti-slip layer increases the friction with the channel steel flange, preventing the channel steel from slipping and ensuring the stable operation of pickling, neutralization, rinsing, and other processes.

[0018] The hooks on both sides are further configured such that the top ends of the hooks are respectively located at the bottom of the movable screw blocks on both sides, one end of the compression spring is welded to the short inner wall of the hook, the other end of the compression spring is welded to a clamping plate, and the inner side of the clamping plate is provided with an anti-slip layer.

[0019] By adopting the above technical solution, the compression spring at the hook pushes the clamping plate to clamp the channel steel with elastic force, and the anti-slip layer increases the friction with the flange of the channel steel. Under the dual action, the channel steel can be firmly clamped. Even during movement and lifting, the channel steel can be prevented from slipping, ensuring the stable progress of pickling, neutralization, rinsing and other processes, reducing process interruptions caused by falling, and improving operational safety and processing quality.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 5 A pickling machine for hot-dip galvanizing of channel steel includes a support slide rail 1.

[0029] Below the support slide rail 1, from left to right, are arranged pickling tank 7, neutralization tank 8 and rinsing tank 9.

[0030] In this embodiment, as Figure 1 and Figure 2 and Figure 5 As shown, the moving mechanism 2 includes a servo motor 201, the output end of which is connected to a moving screw 202. The left and right ends of the moving screw 202 are rotatably connected to the inner walls of the left and right sides of the support slide rail 1, respectively. A moving screw seat 203 is screwed onto the outer wall of the moving screw 202.

[0031] In this embodiment, as Figure 1 and Figure 3 and Figure 5 As shown, the lifting mechanism 3 includes a hydraulic cylinder 301. The top of the hydraulic cylinder 301 is screwed to the middle of the bottom of the movable screw seat 203. A piston rod 302 is provided in the middle of the bottom of the hydraulic cylinder 301. A support plate 4 is provided at the bottom end of the piston rod 302. Telescopic rods 303 are provided between the support plate 4 and the four corners of the movable screw seat 203.

[0032] In this embodiment, as Figure 1 and Figure 3 and Figure 5As shown, the adjustment mechanism 5 includes two bidirectional screws 501. The two ends of the two bidirectional screws 501 are rotatably connected to the bottom sides of the support plate 4. A main drive sprocket 502 is sleeved on the outer wall of the end of one bidirectional screw 501, and a driven drive sprocket 503 is sleeved on the outer wall of the end of the other bidirectional screw 501. A drive chain 504 is meshed on the outer walls of the main drive sprocket 502 and the driven drive sprocket 503. A throttle 505 is provided at the end of the bidirectional screw 501 sleeved with the main drive sprocket 502. Moving screw blocks 506 are screwed onto the outer walls of the two bidirectional screws 501.

[0033] In this embodiment, as Figure 4 As shown, the tops of the hooks 6 on both sides are respectively located at the bottom of the movable screw blocks 506 on both sides. One end of the compression spring 601 is welded to the short inner wall of the hook 6, and the other end of the compression spring 601 is welded to the clamping plate 602.

[0034] The computer software involved in the servo motor and other hardware carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0035] Therefore, the "servo motor," "hydraulic cylinder," etc. involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the pickling machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0036] The pickling machine used for hot-dip galvanizing of channel steel operates as follows:

[0037] First, the operator can turn the handle 505 in the adjustment mechanism 5, so that the handle 505 drives the bidirectional screw 501, which is sleeved with the main drive sprocket 502, to rotate together. At this time, the main drive sprocket 502 will drive the secondary drive sprocket 503 on the other side and the bidirectional screw 501 sleeved with it to rotate synchronously through the drive chain 504 meshed on its outer wall. This causes the moving screw blocks 506 on the outer wall of the two bidirectional screws 501 to move closer or further away from each other, thereby adjusting the distance between the hooks 6 on both sides to match the length of the channel steel.

[0038] The operator can then place the channel steel upside down between the two hooks 6. During this time, the clamping plate 602 on the short inner wall of the hook 6 will come into contact with the two flanges of the channel steel and be squeezed, thereby pushing the compression spring 601 to deform under pressure, so that it stores energy and generates a rebound force. Then the compression spring 601 will push the clamping plate 602 to clamp the channel steel. During this time, the anti-slip layer 603 is closely attached to the flange and increases the friction to prevent the channel steel from slipping.

[0039] Then, the operator can start the servo motor 201 (model: MSMA042A1A) in the moving mechanism 2 through the external controller (model: S7-1200), so that its output end drives the inserted moving screw 202 to rotate on the inner wall of the support slide rail 1, thereby causing the moving screw seat 203 screwed to the outer wall of the moving screw 202 to move along the thread direction to directly above the pickling tank 7. Then, the hydraulic cylinder 301 (model: CDT3MP5) in the lifting mechanism 3 can be started through the external controller, so that it pushes the piston rod 302 down, causing the support plate 4 to drive the channel steel on the adjusting mechanism 5 and the hook 6 to descend until the channel steel is completely immersed in the pickling tank 7 for pickling. During this period, the telescopic rods 303 located at the four corners of the support plate 4 will extend and retract synchronously to assist in stabilization.

[0040] After pickling is completed, the operator can use the hydraulic cylinder 301 to drive the piston rod 302 to rise, and the telescopic rod 303 to retract. The channel steel is lifted off the pickling tank 7 along with the support plate 4. Then, the servo motor 201 is started to run again. The moving screw 202 drives the moving screw seat 203 to move to the top of the neutralization tank 8. Then, the hydraulic cylinder 301 drives the piston rod 302 to descend, and the channel steel enters the neutralization tank 8 for neutralization treatment.

[0041] After neutralization, the hydraulic cylinder 301 drives the channel steel to rise through the piston rod 302, and under the action of the moving mechanism 2, it is moved to the top of the rinsing tank 9. At this time, the hydraulic cylinder 301 descends again to immerse the channel steel in the rinsing tank 9 for rinsing. After rinsing, the piston rod 302 raises the channel steel, the moving screw seat 203 moves to the initial position, and the operator removes the channel steel to complete one pickling process.
