[0002] Hot-dip galvanizing: also known as hot-dip galvanizing and hot-dip galvanizing: is an effective way to prevent metal corrosion. It melts the zinc ingot at high temperature, adds some auxiliary materials, and then immerses the metal structure in the galvanizing tank to adhere a layer of zinc layer to the metal component, thereby achieving the purpose of corrosion protection.

[0003] Existing galvanizing equipment requires workers to manually place the workpiece above the zinc heating furnace. However, due to the high temperature near the zinc heating furnace, workers may be burned by splashing zinc liquid and the high temperature environment. At the same time, since the workpiece is in a stationary state during processing, the high-temperature baking may cause the workpiece to stick. Utility Model Content

A hanging rope 20 is fixedly installed on the bottom of the sliding bridge 17. In the above structure, four sliding rods are provided at the bottom of the top cover 4, which are located inside the heating barrel 2 and are slidably connected to the heating barrel 2, so that when the top cover 4 rises, it drives the four sliding rods to move upward on the inner wall of the heating barrel 2, limiting the top cover 4 so that the top cover 4 will not deviate when it rises.

[0023] In a preferred embodiment, the top cover 4 and the lifting platform 9 have the same height, and the bottom surface of the upper platform 6 is parallel to the top surface of the top cover 4. The fixed rail 5 passes through the lifting platform 9, and the fixed rail 5 is in contact with the inner wall of the lifting platform 9. In the above structure, by starting the motor 7, the motor 7 drives the threaded screw 8 to rotate, and the threaded screw 8 drives the lifting platform 9 to move upward through the rotation of the thread. When the top of the lifting platform 9 is in contact with the bottom of the upper platform 6, the hydraulic cylinder 3 is started, so that the telescopic end of the hydraulic cylinder 3 rises to the maximum height, so that the top cover 4 is in contact with the outer wall of the lifting platform 9, and thus the top cover 4 and the bottom of the lifting platform 9 are made the same height.

[0024] In a preferred embodiment, the number of gears 11 and tooth grooves 14 is two, and the two tooth grooves 14 are symmetrically distributed on the top of the slider 13. The two gears 11 are respectively located above the two tooth grooves 14, and the tooth grooves 14 are engaged with the gears 11. In the above structure, by starting the motor 2 10, the motor 2 10 drives the gear 11 to rotate, and then drives the tooth groove 14 to move at the bottom of the gear 11.

[0025] In a preferred embodiment, the number of motor 2 10, gear 11 and sliding groove 12 is two, and the two motors 2 10, gear 11 and sliding groove 12 are respectively arranged at the bottom of the top cover 4 and the lifting platform 9. In the above structure, by starting motor 2 10 located on the outer wall of the lifting platform 9, motor 2 10 drives gear 11 to rotate, and gear 11 drives the gear groove 14 to move toward the top cover 4 by engaging with the tooth groove 14, thereby driving the slider 13 as a whole to move toward the top cover 4, so that the tooth groove 14 moves from the sliding groove 12 at the bottom of the lifting platform 9 to the inside of the sliding groove 12 at the bottom of the top cover 4. At this time, the tooth groove 14 reaches the bottom of the gear 11 inside the top cover 4, and starting motor 2 10 on the outer wall of the top cover 4 causes the tooth groove 14 to drive the slider 13 to move to the bottom of the top cover 4.

[0026] In a preferred embodiment, the sliding bridge 17 is provided with a protruding round block on the outer wall near the cam 16, and the protruding round block is in contact with the outer wall of the cam 16. In the above structure, by rotating the cam 16, when the protrusion of the cam 16 rotates to the protruding round block on the outer wall of the sliding bridge 17, the cam 16 pushes the sliding bridge 17, causing the sliding bridge 17 to move in the direction of the spring 18.

[0027] In a preferred embodiment, there are two guide rails 19, and the two guide rails 19 are symmetrically arranged on the inner wall of the slider 13. The outer walls of the two guide rails 19 are respectively provided with an extension ring, and the extension ring is located on the side of the sliding bridge 17 away from the spring 18. In the above structure, the sliding distance of the sliding bridge 17 is limited by the extension ring on the outer wall of the guide rail 19. When the sliding bridge 17 slides toward the spring 18, the spring 18 contracts. When the pressure of the sliding bridge 17 disappears, the sliding bridge 17 rebounds to the extension ring on the outer wall of the guide rail 19 through the rebound of the spring 18.

[0028] Working principle: when the device needs to be used, the workpiece is hung on the bottom of the hanging rope 20, and the motor 1 7 is started at this time. The motor 1 7 drives the screw rod 8 to rotate, and the screw rod 8 drives the lifting platform 9 to move upward through the rotation of the thread. When the top of the lifting platform 9 is in contact with the bottom of the upper platform 6, the hydraulic cylinder 3 is started, so that the telescopic end of the hydraulic cylinder 3 rises to the maximum height, so that the top cover 4 is in contact with the outer wall of the lifting platform 9, and thus the top cover 4 is at the same height as the bottom of the lifting platform 9. At this time, the motor 2 10 located on the outer wall of the lifting platform 9 is started, and the motor 2 10 drives the gear 11 to rotate. The gear 11 drives the gear groove 14 to move toward the top cover 4 by meshing with the tooth groove 14, and then drives the slider 13 to move as a whole toward the top cover 4, so that the tooth groove 14 moves from the sliding groove 12 at the bottom of the lifting platform 9 to the inside of the sliding groove 12 at the bottom of the top cover 4. At this time, the tooth groove 14 reaches the bottom of the gear 11 inside the top cover 4 and is started. The motor 2 10 on the outer wall of the top cover 4 causes the tooth groove 14 to drive the slider 13 to move to the bottom of the top cover 4. At this time, the hydraulic cylinder 3 is started to lower the telescopic end of the hydraulic cylinder 3, thereby driving the top cover 4 to fall, so that the top cover 4 reaches the top of the heating barrel 2, so that the workpiece hung at the bottom of the hanging rope 20 enters the heating barrel 2, and the galvanizing liquid in the heating barrel 2 galvanizes the workpiece. At this time, the motor 3 15 is started, so that the motor 3 15 drives the cam 16 to rotate. Through the rotation of the cam 16, when the protrusion of the cam 16 rotates to the protruding round block on the outer wall of the sliding bridge 17, the cam 16 pushes the sliding bridge 17, so that the sliding bridge 17 moves in the direction of the spring 18. When the protruding surface of the cam 16 leaves the sliding bridge 17, the sliding bridge 17 is reset by the rebound force of the spring 18. Through the rotation of the cam 16, the sliding bridge 17 slides back and forth on the outer wall of the guide rail 19, thereby driving the hanging rope 20 to swing, driving the workpiece to swing, and putting it until the workpiece sticks during galvanizing.
