Description

Technical Field

[0001] This utility model relates to the field of spiral steel pipe production technology, specifically a steel coil feeding device for a spiral welded pipe unit. Background Technology

[0002] Spiral steel pipe refers to a steel pipe made by rolling and welding steel plates in a spiral shape. During manufacturing, the steel coil is first placed on a coil support frame, and then the steel plate is processed into a steel pipe and welded using a spiral welding machine. However, because the steel coils used to produce spiral steel pipes are relatively heavy, forklifts or gantry cranes are used to lift the coils and move them to the coil support frame (also known as a coil uncoiling machine). Afterward, the position of the coil is manually adjusted to precisely fit it onto the support shaft on the coil support frame.

[0003] Regarding the aforementioned technologies, when using a forklift to load steel coils onto the coil support frame, the forklift driver's view is obstructed by the coil, thus requiring a worker to stand in front of the forklift to guide the driver. When using a gantry crane to load steel coils onto the support frame, the gantry crane's lifting device is difficult to remove from the coil after it is fitted onto the support shaft on the support frame. Both methods are inconvenient during the steel coil loading process, thus affecting production efficiency.

[0004] In the prior art, as shown in the patent document with authorization announcement number "CN222535926U", the device uses a hoisting mechanism to move the steel coil to the lifting platform, which can facilitate the dismantling of the hoisting equipment; then it drives the mobile trolley to move directionally towards the steel coil support frame, so that the support frame support shaft is accurately inserted into the steel coil. After the loading is completed, the hoisting mechanism can place another steel coil on the lifting platform for later use, and the next loading can be completed by simply moving the trolley.

[0005] However, existing technologies still have significant shortcomings, such as:

[0006] In the existing technology: due to the variety of steel pipe models and sizes produced, the required steel coil sizes are different. However, in the above case, the steel coil pad strips are fixedly installed on the top of the lifting platform, which has poor adaptability when facing steel coils of different sizes. Large steel coils will be unstable due to the small spacing between the pad strips, while small steel coils will not be supported due to the large spacing, which can easily lead to the risk of the steel coil falling. Utility Model Content

[0007] The purpose of this utility model is to provide a steel coil feeding device for a spiral welded pipe unit to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a steel coil feeding device for a spiral welded pipe unit, comprising a steel coil support frame and a track installed on the bottom of one side of the support frame, a moving trolley installed on the top of the track, a placement platform for carrying the steel coil installed on the top of the moving trolley, and a steel coil body placed on the top of the placement platform.

[0009] The placement platform includes four hydraulic rods that are installed around the top of the mobile trolley. The telescopic ends of the hydraulic rods are fixedly installed with placement plates. Steel coil pads are provided on both sides of the top of the placement plate to support and fix the steel coil body.

[0010] An adjustment mechanism is installed between the placement plate and the moving trolley to adjust the distance between the two steel coil pad strips.

[0011] Preferably, the adjustment mechanism includes several vertical rods fixedly installed on both sides of the bottom of the steel coil pad strip, and the bottom ends of the several vertical rods all penetrate through the placement plate and extend to the bottom of the placement plate. A rack is fixedly installed at the top and bottom between every two vertical rods. A rotating rod is installed at the bottom of the placement plate, and gears are fixedly installed on both sides of the surface of the rotating rod. The gears and the rack are meshed together.

[0012] One end of the rotating rod is fixedly equipped with a worm gear, and a servo motor is installed on one side of the bottom of the placement plate. A connecting rod is fixedly installed at the output end of the servo motor, and a worm is installed on the surface of the connecting rod. The worm and the worm gear are meshed together.

[0013] Preferably, the top of the placement plate is provided with sliding grooves on both sides, the top of the placement plate is provided with limiting plates on both sides, and the bottom of the two limiting plates is fixedly installed with sliders, and the sliders are slidably connected to the sliding grooves.

[0014] A locking bolt is installed through the inner wall of the limiting plate, and the bottom end of the locking bolt passes through the limiting plate, the slider and the placement plate in sequence and extends to the bottom of the placement plate to lock the limiting plate.

[0015] Preferably, the top of the placement plate has strip-shaped holes on both sides, the vertical rod passes through the strip-shaped holes and extends to the bottom of the placement plate, and the vertical rod and the strip-shaped holes are slidably connected.

[0016] Preferably, each of the vertical rods has a through hole on its surface, and the through hole is slidably connected to the rack.

[0017] Preferably, a protective shell is fixedly installed on one side of the bottom of the placement plate, and the protective shell is sleeved on the surface of the worm gear and worm to protect the worm gear and worm.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By utilizing the adjustment mechanism, when steel coils of different sizes are placed on top of the placement plate, the servo motor drives the connecting rod and worm gear to rotate. Simultaneously, the meshing connection between the worm gear and the worm wheel drives the rotating rod and the gear mounted on its surface to rotate. The meshing connection between the rack and the gear drives the two vertical rods to move synchronously inward or outward. This allows for adjustment of the distance between the two steel coil pad strips, enabling the adjustment of the steel coil pad strips according to the size of the steel coil body. This prevents the steel coil body from shaking during placement, thus ensuring its stability.

[0020] 2. When it is necessary to load the steel coil body onto the steel coil support frame, the steel coil body is first hoisted onto the placement plate by the hoisting mechanism. After the two steel coil pad strips are adjusted, the steel coil body is placed on the steel coil pad strips. Then, the moving trolley is driven to move towards the steel coil support frame so that the support shaft of the steel coil support frame is accurately inserted into the steel coil body. After the steel coil body is loaded onto the steel coil support frame by this device, the hoisting mechanism can place another steel coil body on the placement plate as a spare for loading the steel coil body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a steel coil feeding device for a spiral welded pipe unit, including a steel coil support frame 1 and a track 2 installed on the bottom of one side of the support frame 1. A moving trolley 3 is installed on the top of the track 2 for moving. A placement platform 4 for carrying the steel coil is installed on the top of the moving trolley 3. The steel coil body 5 is placed on the top of the placement platform 4.

[0029] The placement platform 4 includes four hydraulic rods 41 that run through the top of the mobile trolley 3. A placement plate 42 is fixedly installed at the telescopic end of the hydraulic rods 41. Steel coil pad strips 43 are provided on both sides of the top of the placement plate 42 to support and fix the steel coil body 5. An adjustment mechanism 44 is installed between the placement plate 42 and the mobile trolley 3 to adjust the distance between the two steel coil pad strips 43.

[0030] In this embodiment, when it is necessary to load the steel coil body 5 onto the steel coil support frame 1, the steel coil body 5 is first hoisted onto the placement plate 42 by the hoisting mechanism. After the two steel coil pad strips 43 are adjusted, the steel coil body 5 is placed on the steel coil pad strips 43. Then, the moving trolley 3 is driven to move towards the steel coil support frame 1 so that the support shaft of the steel coil support frame 1 is accurately inserted into the inside of the steel coil body 5. After the device loads the steel coil body 5 onto the steel coil support frame 1, the hoisting mechanism can place another steel coil body 5 on the placement plate 42 as a spare for loading the steel coil body 5.

[0031] Reference Figure 3 as well as Figure 4 As shown, the adjustment mechanism 44 includes several vertical rods 441 fixedly installed on both sides of the bottom of the steel coil pad strip 43, and the bottom ends of the vertical rods 441 all penetrate through the placement plate 42 and extend to the bottom of the placement plate 42. Among them, racks 442 are fixedly installed at the top and bottom between every two vertical rods 441. A rotating rod 443 is installed at the bottom of the placement plate 42, and gears 444 are fixedly installed on both sides of the surface of the rotating rod 443. The gears 444 and the racks 442 are meshed. A worm gear 445 is fixedly installed at one end of the rotating rod 443, and a servo motor 446 is installed on one side of the bottom of the placement plate 42. A connecting rod 447 is fixedly installed at the output end of the servo motor 446, and a worm 448 is installed on the surface of the connecting rod 447. The worm 448 and the worm gear 445 are meshed.

[0032] In this embodiment, when steel coil bodies 5 of different sizes are placed on top of the placement plate 42, the servo motor 446 drives the connecting rod 447 and the worm gear 448 to rotate. While the worm gear 448 rotates, the meshing connection between the worm gear 448 and the worm wheel 445 drives the rotating rod 443 and the gear 444 mounted on its surface to rotate. The meshing connection between the rack 442 and the gear 444 drives the two vertical rods 441 to move synchronously inward or outward. This allows the distance between the two steel coil pad strips 43 to be adjusted, so that the steel coil pad strips 43 can be adjusted according to the size of the steel coil body 5, avoiding the wobbling of the steel coil body 5 during placement and affecting the stability of the steel coil body 5.

[0033] Reference Figure 5 As shown, sliding grooves 46 are provided on both sides of the top of the placement plate 42, and limiting plates 47 are provided on both sides of the top of the placement plate 42. A slider 48 is fixedly installed at the bottom of each of the two limiting plates 47, and the slider 48 is slidably connected to the sliding groove 46. A locking bolt 49 is installed through the inner side wall of the limiting plate 47, and the bottom end of the locking bolt 49 passes through the limiting plate 47, the slider 48 and the placement plate 42 in sequence and extends to the bottom of the placement plate 42 to lock the limiting plate 47.

[0034] In this embodiment, when the steel coil body 5 is placed on top of the steel coil pad strip 43, the operator can move the limiting plate 47 by sliding the slider 48 and the groove 46 to limit the two sides of the steel coil body 5 and prevent the steel coil body 5 from sliding.

[0035] Reference Figure 5 As shown, both sides of the top of the placement plate 42 are provided with strip holes 449, and the vertical rod 441 passes through the strip holes 449 and extends to the bottom of the placement plate 42. The vertical rod 441 and the strip holes 449 are slidably connected.

[0036] In this embodiment, the steel coil pad strip 43 can drive the vertical rod 441 to slide inside the strip hole 449 when it moves, so as to maintain the stability of the steel coil pad strip 43 when it moves.

[0037] Reference Figure 3 As shown, through holes 4401 are provided on the surface of several vertical rods 441, and the through holes 4401 and the rack 442 are slidably connected.

[0038] In this embodiment, when the vertical rod 441 moves, it is possible to avoid the situation where another vertical rod 441 obstructs the movement of the rack 442 and affects the adjustment of the steel coil pad strip 43.

[0039] Reference Figure 2As shown, a protective shell is fixedly installed on one side of the bottom of the placement plate 42, and the protective shell is sleeved on the surface of the worm gear 445 and the worm 448 to protect the worm gear 445 and the worm 448.

[0040] In this embodiment, the worm gear 445 and worm 448 can be protected to prevent external impurities from affecting the meshing between them.

[0041] Working principle: When it is necessary to load the steel coil body 5 onto the steel coil support frame 1, the steel coil body 5 is first hoisted onto the placement plate 42 by the hoisting mechanism. After the two steel coil pad strips 43 are adjusted, the steel coil body 5 is placed on the steel coil pad strips 43. Then, the moving trolley 3 is driven to move towards the steel coil support frame 1 so that the support shaft of the steel coil support frame 1 is accurately inserted into the steel coil body 5.

[0042] Furthermore, when the steel coil pad strip 43 is adjusted, the servo motor 446 drives the connecting rod 447 and the worm gear 448 to rotate. At the same time as the worm gear 448 rotates, the meshing connection between the worm gear 448 and the worm wheel 445 drives the rotating rod 443 and the gear 444 mounted on its surface to rotate. The meshing connection between the rack 442 and the gear 444 drives the two vertical rods 441 to move inward or outward synchronously, thereby adjusting the distance between the two steel coil pad strips 43 and supporting the steel coil bodies 5 of different sizes.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
