Description

Technical Field

[0001] This invention relates to the field of tooling and fixtures for hot-dip galvanizing, and in particular to a tooling and fixture for air cooling coils. Background Technology

[0002] Currently, most products involved in hot-dip galvanizing processing services are welded structural components made of one or more of the following: channel steel, angle steel, plates, and pipes. The galvanizing method involves hot-dip galvanizing both the inner and outer surfaces. Another type of hot-dip galvanized product is the high-efficiency air cooling coil, which is a cooling coil formed by assembling several individual coils in a fixed number of rows and columns. When hot-dip galvanizing this coil, the galvanizing process forms a zinc layer on the outer surface; due to the structure and internal flow medium, the inner surface cannot be galvanized. This process generates significant buoyancy.

[0003] A special tooling fixture for air cooling coils, disclosed in Chinese Patent Publication No. CN210796591U, includes: a main body, anti-buoyancy mechanisms at both ends of the main body, and multiple workpiece suspension mechanisms below the main body; travel tracks are respectively provided on both sides of the main body; the workpiece suspension mechanisms include: a movable travel frame, pressure feet, and multiple pressure foot support rods; travel wheels are respectively provided at both ends of the movable travel frame, and the travel wheels are placed in corresponding travel tracks; the top of the pressure foot support rod is fixed to the bottom of the movable travel frame, and the bottom of the pressure foot support rod is fixed to the pressure foot, with multiple suspension holes evenly distributed on the pressure foot. The anti-buoyancy mechanism includes: a lifting bar, a chain, a guide sprocket, a sprocket shaft, and a sprocket fixing clamp. This utility model can suspend air cooling coils of different lengths and widths during galvanizing, improving the adaptability of the equipment and production efficiency.

[0004] In actual use, the presence of the sprocket fixing plate on this equipment prevents it from moving effectively laterally. It can only adjust its height above the galvanizing tank. This makes the air cooling coil relatively static during loading operations. Furthermore, the presence of the sprocket fixing plate makes it easy for users to interfere with the sprocket fixing plate and the steel cable on it when placing the air cooling coil.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0014] 1. In this invention, the movable guide rail set on the top of the factory building allows the equipment to move freely, thereby detaching the hanger from the galvanizing tank. This makes it quicker and more convenient for workers to fix the air cooling coil. At the same time, the movable guide rail is located on the top of the factory building, so that the equipment will not interfere with the air cooling coil when it moves, and it can be adapted to the placement position of the air cooling coil.

[0015] 2. In this invention, by setting an adjusting rod and a movable block that can be fixed, the buoyancy of the air cooling coil after it is placed in the galvanizing bath will not cause the movable frame to tilt or shift, thereby effectively preventing the air cooling coil from tilting and ensuring the product quality of the air cooling coil after galvanizing. At the same time, the adjusting rod of the telescopic structure can effectively adapt to the irregularly shaped air cooling coil.

[0016] 3. In this invention, by setting a spacing adjustment mechanism, the support rod can adaptively adjust the spacing according to the length of the air cooling coil during use, thereby adapting to the usage requirements. In addition, a limiting block for locking is added inside the support rod of the equipment, thereby effectively fixing and limiting the air cooling coil. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0027] Example: Figure 1-8 As shown, an air cooling coil tooling fixture includes a hanger 1 and a fixed frame 3. The hanger 1 is installed on the top of the factory building. The bottom of the hanger 1 is bolted to a movable guide rail 8. The fixed frame 3 is plate-shaped. Movable mechanisms 2 are installed on both sides of the fixed frame 3. The movable mechanisms 2 are snapped into the movable guide rails 8 and are slidably connected to them. A steel cable winding mechanism is installed on the top of the fixed frame 3. Steel cables are wound around the steel cable winding mechanism. The free ends of the steel cables longitudinally penetrate the fixed frame 3 and extend to the bottom outer side of the fixed frame 3. There are four sets of steel cables arranged in a rectangular array. Movable frames 4 are installed on the free ends of the four sets of steel cables. Movable frames 4 are rectangular frames. The bottom of the movable frames 4 is equipped with a coil tooling fixture. A spacing adjustment mechanism is provided at the connection between the coil tooling fixture and the movable frames 4. Buoyancy fine adjustment mechanisms 13 are provided on the corresponding side walls of the fixed frame 3 and the movable frames 4. An electronic level 20 is fixedly installed on the top of the movable frames 4.

[0028] In some embodiments, the boom 1 is preferably installed on the top of the factory building, and the movable guide rail 8 is installed on the path where the air cooling coil needs to be moved. When the air cooling coil needs to be galvanized, the user drives the movable mechanism 2 to move the coil fixture to the position where the air cooling coil needs to be fixed. At this time, the drive spacing adjustment mechanism adapts the coil fixture to the width of the air cooling coil and fixes the air cooling coil on the coil fixture. Then, the height of the coil fixture is reset, and the movable mechanism 2 is driven to move the air cooling coil above the galvanizing tank. At the same time, the drive cable winding mechanism releases the cable winding mechanism into the galvanizing tank. Since the air cooling coil is a hollow structure, it is affected by buoyancy, causing the movable frame 4 to shift. At this time, the electronic level 20 is triggered, causing the buoyancy fine adjustment mechanism 13 to be driven, thereby adjusting the position of the air cooling coil and making it fully enter the galvanizing tank.

[0029] like Figure 2As shown, the mounting bracket 3 has four sets of mounting holes 16 arranged in a rectangular array. The mounting holes 16 correspond to the four sets of steel cables. The steel cables are located inside the mounting holes 16. The inner sidewall of the mounting holes 16 is rotatably mounted with anti-wear wheels 9, and the steel cables are placed on the anti-wear wheels 9.

[0030] When the cable winding mechanism releases the cable, the cable can slide on the anti-wear wheel 9 to prevent the cable from directly rubbing against the fixed frame 3.

[0031] like Figure 1 and Figure 6 As shown, the movable mechanism 2 includes a mounting shell 39, a third motor 40, a drive gear 41, and an auxiliary wheel 42. The mounting shell 39 is arranged in an inverted U-shape. The drive gear 41 is rotatably mounted on the inner walls of both sides of the mounting shell 39, and the auxiliary wheel 42 is rotatably mounted on the bottom of the mounting shell 39. The third motor 40 is fixedly mounted on the outer wall of the mounting shell 39. The output end of the third motor 40 passes through the mounting shell 39 laterally and is fixedly connected to the rotating shaft of the drive gear 41. The top of the moving guide rail 8 is provided with a slot that matches the drive gear 41. The bottom inner side of the slot is provided with teeth that mesh with the drive gear 41. The outer wall of the auxiliary wheel 42 is fitted against the top of the moving guide rail 8.

[0032] When the coil fixture needs to be moved, the third motor 40 drives the drive gear 41 to rotate. Since the top of the moving guide rail 8 has a slot that matches the drive gear 41, the fixed frame 3 moves, thereby driving the coil fixture to move and complete the movement of the air cooling coil.

[0033] like Figure 1 and Figure 2 As shown, the cable winding mechanism includes a winding wheel 7, a guide wheel assembly 6, a connecting frame 15, a first dual-axis motor 14, a first gear 10, and a second gear 11. The connecting frame 15 is fixedly installed on the top of the fixed frame 3. The winding wheel 7 is rotatably installed on the connecting frame 15. There are four sets of winding wheels 7 arranged in a rectangular array. The free end of the cable is fixedly connected to the winding wheel 7. The guide wheel assembly 6 is fixedly installed on the top of the fixed frame 3 outside the winding wheel 7. The cable is sleeved on the guide wheel assembly 6. The first dual-axis motor 14 is fixedly installed on the connecting frame 15. The second gear 11 is fixedly installed on the output end of the first dual-axis motor 14. The first gear 10 is fixedly installed on the shaft of the winding wheel 7. The first gear 10 and the second gear 11 are meshed.

[0034] When the first dual-axis motor 14 is driven, the first gear 10 rotates, driving the second gear 11 to rotate, which in turn causes the winding wheel 7 to rotate, thus completing the release and winding of the steel cable.

[0035] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the coil tooling fixture includes a support rod 5, an auxiliary rod 45, an electric push rod 44, an installation rod 43, a limiting block 48, a coil groove 22, a sliding groove 47, and a slider 46. The support rod 5 is slidably installed at the bottom of the movable frame 4. The support rod 5 is symmetrically arranged, and the position of the support rod 5 corresponds to the position of the moving guide rail 8. Several sets of coil grooves 22 are equidistantly arranged on the outer side of the support rod 5. The coil grooves 22 are inclined with an inclination angle of 45 degrees.

[0036] Place the support rod 5 at the bend of the air cooling coil. The user then inserts the air cooling coil into the coil groove 22. The coil groove 22 can then engage the air cooling coil, thus fixing and limiting its position. Because the coil groove 22 is set with an inclined structure and an inclination angle of 45 degrees, the air cooling coil can be prevented from falling off when it is lifted.

[0037] like Figure 7 and Figure 8 As shown, the support rod 5 consists of two sets of identical auxiliary rods 45. Electric push rods 44 are fixedly installed on the corresponding side walls of the two sets of auxiliary rods 45. The electric push rods 44 are placed at an angle. The telescopic end of the electric push rods 44 is fixedly installed with rods 43. The rods 43 are fixedly installed with limit blocks 48 on the side wall near the coil groove 22. The limit blocks 48 are in an inclined shape and are located at the intervals between two adjacent sets of coil grooves 22. A sliding groove 47 is opened on the support rod 5 at the intervals between two adjacent sets of coil grooves 22. A slider 46 is built into the sliding groove 47. The slider 46 is fixedly connected to the limit block 48.

[0038] Once the air cooling coil is embedded in the coil slot 22, the user drives the electric push rod 44, which causes the mounting rod 43 to move laterally in an inclined position, thereby allowing the limiting block 48 to lock the opening of the coil slot 22.

[0039] like Figure 3 As shown, the spacing adjustment mechanism includes an adjustment frame 17, an auxiliary gear 23, a rack 24, a second dual-axis motor 19, a threaded rod 21, and a fixing plate 18. The adjustment frame 17 is fixedly connected to the coil tooling hanger. A rack 24 is installed on the inner walls of the front and rear sides of the movable frame 4. An auxiliary gear 23 that meshes with the rack 24 is rotatably installed on the adjustment frame 17. A fixing plate 18 is fixedly installed at the center of the inner walls on both sides of the movable frame 4. A second dual-axis motor 19 is fixedly installed on the top of the fixing plate 18. A threaded rod 21 is fixedly installed at the free end of the second dual-axis motor 19. The threaded rod 21 passes through the adjustment frame 17 laterally and is rotatably connected to the two side walls of the movable frame 4. The threaded rod 21 is threadedly connected to the adjustment frame 17. The internal threads of the two sets of adjustment frames 17 are arranged in opposite directions.

[0040] When the length of the air cooling coil needs to be adjusted, the user drives the second dual-axis motor 19 to rotate the threaded rod 21. At this time, the two sets of adjustment brackets 17 move towards each other or away from each other, thereby adjusting the length of the air cooling coil and completing the fixed limit of the air cooling coil.

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, the buoyancy fine-tuning mechanism 13 includes an adjusting rod 25, a rod body 27, a movable groove 12, a locking block 26, a first motor 29, a limiting plate 30, a guide rod 31, a first threaded screw 32, and a movable block 33. A movable groove 12 is provided in the center of the fixed frame 3. Rod bodies 27 are fixedly installed on the inner walls of both sides of the movable groove 12. Movable blocks 33 are sleeved on the rod body 27. There are two sets of movable blocks 33, which are slidably connected to the rod body 27. An adjusting rod 25 is hinged to the bottom of the movable block 33. The free end of the adjusting rod 25 is hinged to the top of both side walls of the movable frame 4. Locking holes 2 are equidistantly arranged on both the front and rear side walls of the rod body 27. 8. A limiting plate 30 is fixedly installed on the inner side wall of the movable block 33. A first threaded rod 32 is rotatably installed on the side wall of the limiting plate 30 near the rod body 27. Guide rods 31 are fixedly installed on both sides of the first threaded rod 32 on the limiting plate 30. A locking block 26 is sleeved on the guide rod 31 and the first threaded rod 32. The locking block 26 is slidably connected to the guide rod 31 and threadedly connected to the first threaded rod 32. The locking block 26 has a C-shaped structure and matches the locking hole 28. A first motor 29 is fixedly installed on the other side wall of the limiting plate 30. The output end of the first motor 29 passes through the limiting plate 30 laterally and is fixedly connected to the first threaded rod 32.

[0042] When the cable winding mechanism releases or winds up the cable, the limiting plate 30 slides on the rod 27, and the adjusting rod 25 changes position. After the coil is completely off the ground, the limiting plate 30 is positioned. The first motor 29 drives the first threaded screw 32 to rotate, which causes the locking block 26 to move laterally, thereby causing the locking block 26 to be embedded in the locking hole 28 to fix the limiting plate 30.

[0043] like Figure 5As shown, the adjusting rod 25 includes an inner rod 34, a second threaded screw 35, an outer rod 36, a second motor 37, and a motor slot 38. The bottom end of the outer rod 36 is hinged to the movable frame 4. The inner rod 34 is slidably installed inside the outer rod 36. The second threaded screw 35 is rotatably installed on the bottom inner side of the outer rod 36. The second threaded screw 35 is sleeved on the inner rod 34 and threadedly connected to the inner rod 34. A motor slot 38 is provided at the bottom end of the outer rod 36. The second motor 37 is fixedly installed on the inner side wall of the motor slot 38. The output end of the second motor 37 passes through the motor slot 38 laterally and is fixedly connected to the second threaded screw 35.

[0044] When the coil needs to enter the galvanizing bath, it tilts due to buoyancy. At this time, the second motor 37 drives the second threaded screw 35 to rotate, causing the outer rod 36 at the inner rod 34 to squeeze the tilted coil, thus completing the horizontal adjustment of the coil.

[0045] Working principle:

[0046] The user's third motor 40 drives the drive gear 41 to rotate. Because the top of the moving guide rail 8 has a slot that matches the drive gear 41, the device moves to the placement position of the air cooling coil. At this point, the first dual-axis motor 14 is driven, causing the first gear 10 to rotate, which in turn drives the second gear 11 to rotate. This causes the winding wheel 7 to rotate, releasing the steel cable and moving it above the air cooling coil. Then, the second dual-axis motor 19 is driven, driving the threaded rod 21 to rotate. At this time, the two sets of adjusting brackets 17 move towards or away from each other, thus adapting to the air cooling coil. After the air cooling coil is embedded in the coil groove 22, the user drives the electric push rod 44, which causes the mounting rod 43 to move laterally in an inclined position. This allows the limiting block 48 to lock the opening of the coil groove 22. After locking, the user resets the movable frame 4, moves the equipment above the galvanizing tank, and releases the movable frame 4 into the tank. Before entering the tank, if the buoyancy changes, the user drives the adjusting rod 25 to level the air cooling coil. After leveling, the movable block 33 and the rod are limited.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
