Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing processing of mechanical parts, in particular to a galvanizing machine with a rapid film-forming structure. Background Art

[0002] During the installation and erection of transmission lines, a large number of mechanical metal accessories are needed. In order to ensure the safety of transmission lines and the service life of equipment, their surfaces need to be treated with anti-corrosion. Galvanizing the surface of metal parts is a common anti-corrosion measure, and hot-dip galvanizing is a galvanizing method that can be mass-produced.

[0003] The existing hot-dip galvanizing method usually adopts a pre-set galvanizing furnace, injecting zinc liquid into the galvanizing furnace and keeping it heated so that the zinc liquid in the galvanizing furnace is at about 500 degrees Celsius, and immersing the steel components in the zinc liquid through the connecting components for a certain period of time, so that a zinc layer adheres to the surface of the steel components, thereby achieving the purpose of corrosion protection.

[0004] The steel components used in transmission lines usually have holes inside them, and the connection of the steel components is usually achieved by inserting a hook into the hole inside the steel component and hooking it up, so as to ensure that the steel component will not fall off when immersed in zinc liquid. However, this immersion method will easily cause obstruction between the hook and the inner surface of the hole, which will result in the zinc liquid not being able to achieve the ideal galvanizing effect on the inner surface of the hole. In view of this, we propose a galvanizing machine with a rapid film-forming structure. Utility Model Content

[0005] The purpose of the utility model is to provide a galvanizing machine with a rapid film-forming structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a galvanizing machine with a rapid film-forming structure, comprising a mounting frame, a hook being rotatably mounted on the inner wall of the bottom of the mounting frame, and a swing mechanism being provided on the outer side of the mounting frame, the swing mechanism comprising:

[0007] A drive motor is fixedly mounted on the top outer wall of the mounting frame, an output end of the drive motor is connected to a sprocket via a chain transmission, a top end of the hook passes through the sprocket, and the sprocket is fixedly connected to the hook;

[0008] The telescopic cylinder is fixedly connected to the top inner wall of the mounting frame, a wave groove is formed on the arc-shaped outer wall of the telescopic cylinder, an arc-shaped clamping block is fixedly installed on the inner wall of the hook, and the arc-shaped clamping block is arranged inside the wave groove. The bottom end of the telescopic cylinder is rotatably connected to the top end of the connecting column, the bottom end of the connecting column is movably connected to the top end of the arc-shaped connecting member, the bottom end of the arc-shaped connecting member is movably connected to the end of the sliding rod, and the other end of the sliding rod is fixedly installed with a magnetic member.

[0011] Preferably, an annular groove adapted to the positioning ring is provided on the arc-shaped inner surface of the rotating drum, and the positioning ring is arranged in the annular groove, so that the rotating drum can stably rotate on the arc-shaped outer wall of the hook.

[0012] Preferably, the magnetic properties of the magnetic member and the magnetic strip are the same, so that when the magnetic member is driven by the slide rod and approaches the center of the rotating drum in the horizontal direction, the repulsive force between the magnetic member and the magnetic strip causes the rotating drum to have a rotation tendency on the curved outer wall of the hook.

[0013] Preferably, the convex balls are arranged at the edges of the arc groove near both sides, and the number of the convex balls is arranged in several groups, and the several groups of convex balls are evenly distributed on the arc groove in a circular array, so that the rotation of the drum will cause the convex balls to continuously contact the inner wall of the through hole opened in the steel component and lift it up.

[0015] Preferably, the bottom magnetism of the magnetic top block is the same as that of the magnetic member, so that when the magnetic member moves toward the center of the drum, the repulsive force between the magnetic member and the magnetic top block causes the magnetic top block to move away from the center of the drum.

[0016] Compared with the prior art, the present invention provides a galvanizing machine with a rapid film-forming structure, which has the following beneficial effects:

[0017] 1. The galvanizing machine with a rapid film-forming structure is provided with a swing mechanism, which cooperates with the guidance and restriction of the wave groove and the arc-shaped clamping block, so that the telescopic cylinder cooperates with the connecting column and the arc-shaped connecting piece to cause the slide rod and the magnetic piece to produce a small reciprocating motion in the horizontal direction. Due to the magnetic repulsion between the magnetic piece and the magnetic strip, the rotating drum tends to rotate on the arc-shaped outer wall of the hook, thereby causing the convex ball to continuously contact the inner wall of the through hole opened in the steel component and lift it up, so that the zinc liquid can enter the through hole, thereby making the galvanizing effect of the steel component more complete and avoiding the occurrence of galvanizing dead corners.

[0018] 2. The galvanizing machine with a rapid film-forming structure has a sliding cavity and a magnetic top block at the bottom of the arc-shaped groove. The repulsive force between the magnetic part and the magnetic top block causes the magnetic top block to move toward the side away from the center of the rotating drum, thereby producing a slight knocking action on the steel component, causing the bubbles that may be generated on the surface of the steel component immersed in the zinc liquid to move upward and detach, thereby ensuring the integrity of the galvanizing on the surface of the steel component and avoiding incomplete galvanizing.

DETAILED DESCRIPTION

[0026] like Figures 1-6As shown, the utility model provides a technical solution: a galvanizing machine with a rapid film-forming structure, comprising a mounting frame 1, a hook 2 is rotatably installed on the bottom inner wall of the mounting frame 1, a swing mechanism is provided on the outer side of the mounting frame 1, and the swing mechanism includes a drive motor 3, a chain 4, a sprocket 5, a telescopic cylinder 6, a wave groove 7, an arc-shaped block 8, a connecting column 9, an arc-shaped connecting piece 10, a slide rod 11, a magnetic piece 12, a rotating drum 13, a positioning ring 14, an arc-shaped groove 15, a convex ball 16 and a magnetic strip 17.

[0027] In one embodiment of the present utility model, a driving motor 3 is fixedly mounted on the top outer wall of the mounting frame 1, and the output end of the driving motor 3 is connected to a sprocket 5 through a chain 4. The top of the hook 2 passes through the sprocket 5, and the sprocket 5 is fixedly connected to the hook 2. The top of the telescopic cylinder 6 is fixedly connected to the inner wall of the top of the mounting frame 1. A wave groove 7 is provided on the arc-shaped outer wall of the telescopic cylinder 6. An arc-shaped block 8 is fixedly mounted on the inner wall of the hook 2. The arc-shaped block 8 is arranged inside the wave groove 7. The bottom end of the telescopic cylinder 6 is rotated and connected to the mounting frame 1. It is connected to the top of the connecting column 9, and the bottom end of the connecting column 9 is movably connected to the top of the arc-shaped connecting member 10, and the bottom end of the arc-shaped connecting member 10 is movably connected to the end of the slide rod 11. The other end of the slide rod 11 is fixedly mounted with a magnetic member 12, and a rotating drum 13 is rotatably mounted on the outer wall of the hook 2, and a positioning ring 14 is fixedly mounted on the arc-shaped outer wall of the hook 2. An arc-shaped groove 15 is provided on the arc-shaped outer wall of the rotating drum 13, and a convex ball 16 is fixedly mounted on the inner surface of the arc-shaped groove 15. A magnetic strip 17 is fixedly mounted on the inner wall of the rotating drum 13.

[0028] Furthermore, a pull ring is fixedly installed on the top outer wall of the mounting frame 1 so that it can be used in conjunction with an external crane during batch galvanizing operations. At the same time, there are multiple groups of hooks 2, and multiple groups of hooks 2 are evenly distributed in a linear array at the bottom of the mounting frame 1, so that multiple workpieces to be galvanized can be hung at the bottom of a group of mounting frames 1, thereby facilitating large-scale production operations. In addition, the output end of the driving motor 3 is passed through and fixedly connected to another group of sprockets 5, so that the hooks 2 are driven by the driving motor 3 and the transmission of the sprockets 5 and the chains 4 to rotate at the bottom of the mounting frame 1, thereby driving the steel components hung at the bottom of the hooks 2 to rotate slowly in the zinc liquid, so as to improve the contact efficiency between the steel components and the zinc liquid. In other words, the telescopic cylinder 6 includes a fixed part and a transmission part, and the fixed part and the transmission part can only undergo relative displacement in the vertical direction. The fixed part is fixedly connected to the top inner wall of the mounting frame 1, and the transmission part is arranged inside the hook 2, and the arc-shaped outer surface of the transmission part fits the inner surface of the hook 2. Specifically, the wave groove 7 is opened on the arc-shaped outer surface of the transmission part, so that when the hook 2 rotates with the sprocket 5, due to the restriction of the arc-shaped block 8 and the wave groove 7, the transmission part of the telescopic cylinder 6 will perform a small reciprocating motion in the vertical direction, and since the bottom end of the telescopic cylinder 6 is rotationally connected to the connecting column 9, the up and down movement of the telescopic cylinder 6 will drive the connecting column 9 to move in the vertical direction, and there will be no motion interference between the two.

[0029] In addition, the inner wall of the hook 2 is provided with a perforated plate for the slide bar 11 to slide in the horizontal direction, so that the up and down movement of the connecting column 9 cooperates with the arc-shaped connecting piece 10 to drive the slide bar 11 to reciprocate in the horizontal direction. At the same time, an annular groove adapted to the positioning ring 14 is provided on the arc-shaped inner surface of the rotating drum 13, and the positioning ring 14 is arranged in the annular groove, so that the rotating drum 13 can stably rotate on the arc-shaped outer wall of the hook 2. Specifically, the magnetic element 12 and the magnetic strip 17 have the same magnetism, so that when the magnetic element 12 is driven by the slide bar 11 and approaches the center side of the rotating drum 13 in the horizontal direction, due to the gap between the magnetic element 12 and the magnetic strip 17 Repulsive force is generated to cause the rotating drum 13 to rotate on the arc-shaped outer wall of the hook 2, and due to the resistance during the movement of the zinc liquid and the steel component, the rotating drum 13 will rotate relative to the through hole opened on the steel component. Furthermore, the convex balls 16 are arranged at the edges of the arc-shaped groove 15 close to both sides, and the number of the convex balls 16 is arranged in several groups, and the several groups of convex balls 16 are evenly distributed on the arc-shaped groove 15 in a circular array, so that the rotation of the rotating drum 13 will cause the convex balls 16 to continuously contact the inner wall of the through hole opened in the steel component and lift it up, so that the zinc liquid can enter the through hole, thereby making the galvanizing effect of the steel component more complete and avoiding the occurrence of galvanizing dead corners.

[0030] In an embodiment of the present invention, a sliding cavity is provided on the bottom inner wall of the arc-shaped groove 15, and a magnetic top block 18 is movably provided on the inner wall of the sliding cavity. Specifically, there are three groups of sliding cavities, and the three groups of sliding cavities are evenly distributed on the inner wall of the arc-shaped groove 15 in a circular array, and the sliding cavity is provided at the bottom end of the arc-shaped groove 15. In addition, the bottom magnetism of the magnetic top block 18 is the same as the magnetism of the magnetic member 12, so that when the magnetic member 12 moves toward the center of the rotating drum 13, the repulsive force between the magnetic member 12 and the magnetic top block 18 causes the magnetic top block 18 to move toward the side away from the center of the rotating drum 13, thereby producing a slight knocking action on the steel component, causing the bubbles that may be generated on the surface of the steel component immersed in the zinc liquid to move upward and detach, thereby ensuring the integrity of the galvanizing on the surface of the steel component and avoiding incomplete galvanizing.

[0031] In the present invention, when in use, the through hole on the steel component to be galvanized is aligned with the hook 2 and placed until it reaches the bottom of the hook 2. At this time, the mounting frame 1 is driven above the galvanizing furnace by an external lifting device, and the height of the mounting frame 1 is controlled to completely immerse the steel component on the hook 2 in the zinc liquid of the galvanizing furnace. At this time, the driving motor 3 is started, and the chain 4 and the sprocket 5 are coordinated to drive the hook 2 to rotate slowly, so that the steel component placed on the hook 2 can fully contact the zinc liquid, thereby realizing the galvanizing of the steel component. At the same time, by providing The swing mechanism, in conjunction with the guidance and restriction of the wave groove 7 and the arc-shaped block 8, enables the telescopic cylinder 6 to cooperate with the connecting column 9 and the arc-shaped connecting member 10 to produce a small reciprocating motion in the horizontal direction on the slide rod 11 and the magnetic member 12. Due to the magnetic repulsion between the magnetic member 12 and the magnetic strip 17, the rotating cylinder 13 is prompted to rotate on the arc-shaped outer wall of the hook 2, thereby causing the convex ball 16 to continuously contact the inner wall of the through hole opened in the steel component and lift it up, so that the zinc liquid can enter the through hole, thereby making the galvanizing effect of the steel component more complete and avoiding the occurrence of galvanizing dead corners.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
