Description

Technical Field

[0001] The invention belongs to the technical field of transformer production, and in particular relates to a coil-set hard-connected hanger. Background Art

[0002] After the transformer coil is wound, it needs to be assembled with the iron core. This operation involves fitting the coil onto the corresponding core post. For transformer coils with slightly larger capacity, a hoist is required to complete this operation. The core requirement for this operation is stability for the hoist and the operator. On the one hand, the coil and core must be accurately fitted, and on the other hand, the coil and core must not collide. There are many types of hoists currently used in production sites, but most of them have one thing in common, which is the use of rope hoists. The biggest risk of using such hoists in the above operation scenarios is that the lateral position of the coil is not stable during the descent process. The operator needs to closely monitor to ensure that there is no excessive lateral shaking during the process of the coil moving downward and fitting onto the core post. In order to complete this operation, multiple experienced and capable personnel are usually required to operate it. Even so, this operation still has safety hazards. If you are not careful, it may cause damage to the coil or iron core. Summary of the Invention

[0003] The present invention provides a coil-encased hard-connected hanger to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0005] A coil-suited hard-connected sling comprises a supporting part, a lifting part, a transition part and a working part. The lifting part is mounted on the supporting part, the transition part is mounted on the bottom of the lifting part, and the working part is connected to the bottom of the transition part.

[0006] The support section includes a base, columns, a crossbeam, a hinged boss, a sleeve, and a driving gear. The base supports the entire device on the ground. The base has a column, and a crossbeam is located on top of the column. The front end of the crossbeam has a sleeve that fits inside the sleeve, and the front of the crossbeam, near the sleeve, has a hinged boss, and the driving gear is hingedly installed inside the hinged boss. The lifting section includes a top plate, a through-hole, side plates, a gear ring, a threaded boss, a reel, and a rope. The top plate has a through-hole at the center of the top, with a side plate on each side of the through-hole. The side plates are hinged with a reel, and the rope is wound around the reel and passes downward through the through-hole. The bottom of the top plate is connected to the gear ring, which meshes with the driving gear for transmission. Four threaded bosses are evenly distributed around the bottom of the gear ring, and screws are installed on the threaded bosses to fine-tune the position of the adapter. The adapter consists of a core shaft, a center disk, guide rails, lugs, eyelets, and a screw. The core shaft has a eyelet at the top, which is connected to a rope. The core shaft has a center disk at the bottom, with four evenly spaced guide rails at the bottom. Each guide rail has a lug at the front and back ends, and a screw is hinged between the lugs. The working section consists of a coil, a hook, a tab, and a slider. The coil is attached from the bottom via four evenly spaced hooks. The hooks are connected to the tabs at the top, and the tabs have sliders at the top. The sliders fit inside the guide rails, and the sliders have a threaded hole in the center that connects to the screw, enabling the assembly of the working section and adapter.

[0007] Furthermore, the support is composed of two cross bars that are separated from each other. If necessary, rollers are installed at the bottom of the support to facilitate the transfer of the entire spreader.

[0008] Furthermore, a first mounting plate is provided on the rear side of the hinged boss, and a motor is mounted on the first mounting plate to drive the driving gear to rotate.

[0009] Furthermore, the side of the top plate is provided with a second mounting plate, and another motor is installed on the second mounting plate to drive the reel to rotate and lift the adapter part and the working part.

[0010] Furthermore, ribs are provided between the core shaft, the center disk and the guide rails, and the ribs reinforce the overall structural strength of the transition portion to ensure a safe and reliable structure.

[0011] Furthermore, the hook and the coil are bundled and wrapped with a tape to ensure a stable connection.

[0012] The beneficial effects of the present invention are:

[0013] The present invention is used for the set operation of coils and core columns during the production of transformer boxes. It has a set of flexible steel cable lifting mechanisms, which can conveniently lift the coil. Even if the lifting point and the coil are not on the same vertical line, the coil can be allowed to move horizontally a small amount during the lifting process. The coil can be safely lifted under the supervision of the operator. When the coil is lifted to the bottom of the lifting cylinder, the side screws are used to tighten the main shaft to form a hard connection. At this time, the coil descending process is a stable vertical downward movement. The screws can be used to fine-tune the position of the coil to ensure that the coil is stable and controllable during the descent process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the present invention.

[0019] See also Figure 1-Figure 3 The coil-suited hard-connected sling shown includes a supporting part 10, a lifting part 20, a connecting part 30 and a working part 40. The lifting part 20 is installed on the supporting part 10, the connecting part 30 is installed at the bottom of the lifting part 20, and the working part 40 is connected to the bottom of the connecting part 30.

[0020] The support portion 10 includes a support 11, a column 12, a crossbeam 13, a first mounting plate 14, a hinged boss 15, a sleeve 16, and a driving gear 17. The support 11 is composed of two crossbars that diverge from each other and support the entire device on the ground. If necessary, rollers are installed at the bottom of the support 11 to facilitate the transfer of the entire sling. The support 11 has a column 12, and the top of the column 12 has a crossbeam 13. The front end of the crossbeam 13 has a sleeve 16, and the sleeve 16 is mounted inside the lifting portion 20. The front portion of the crossbeam 13 near the sleeve 16 has a hinged boss 15, and the driving gear 17 is hingedly mounted inside the hinged boss 15. The rear side of the hinged boss 15 has a first mounting plate 14, and the first mounting plate 14 is mounted on the motor to drive the driving gear 17 to rotate.

[0021] The lifting part 20 includes a top plate 21, a through hole 22, a side plate 23, a second mounting plate 24, a gear ring 25, a threaded boss 26, a reel 27 and a rope 28. The top plate 21 has a through hole 22 in the center of the top, and a side plate 23 on each side of the through hole 22. The reel 27 is hinged on the side plate 23, and the rope 28 is wound on the reel 27. The rope 28 passes downward through the through hole 22. The bottom of the top plate 21 is connected to the gear ring 25. The connection method between the top plate 21 and the gear ring 25 can be a firm connection method such as welding or pin connection. The gear ring 25 is engaged with the driving gear 27 for transmission. Four threaded bosses 26 are evenly distributed around the bottom of the gear ring 25. Screws are installed on the threaded boss 26 for fine-tuning the position of the adapter 30. The side of the top plate 21 has a second mounting plate 24. Another motor is installed on the second mounting plate 24 to drive the reel 27 to rotate, lifting the adapter 30 and the working part 40.

[0022] The adapter part 30 includes a core shaft 31, a center disk 32, a guide rail 33, a hanging ear 34, a rib 35, a lifting ring 36 and a screw 37. The top of the core shaft 31 is provided with a lifting ring 36, and the lifting ring 36 is connected to the rope 28. The bottom of the core shaft 31 is provided with a center disk 32, and the bottom of the center disk 32 is provided with four evenly distributed guide rails 33. The front and rear ends of the guide rails 33 are each provided with a hanging ear 34, and the screw 37 is hinged between the hanging ears 34. There are ribs 35 between the core shaft 31, the center disk 32 and the guide rail 33. The ribs 35 reinforce the overall structural strength of the adapter part 30 to ensure that the structure is safe and reliable.

[0023] The working part 40 includes a coil 41, a hook 42, a wrapping tape 43, an ear piece 44 and a slider 45. The coil 41 is hung from the bottom by four hooks 42 evenly distributed around it. The wrapping tape 43 is used to bundle the hook 42 and the coil 42 to ensure their stable connection. The top of the hook 42 is connected to the ear piece 44. The top of the ear piece 44 has a slider 45. The slider 45 is fitted and installed inside the guide rail 33. The center of the slider 45 has a threaded hole and is threadedly connected to the screw 37 to realize the installation of the working part 40 and the adapter part 30.

[0024] The working principle of the present invention is as follows: after the coil is wound, its surface is usually insulated. Four hooks 42 are used to hang the coil 41 from the bottom, and then the strapping 43 is used to complete the binding. Subsequently, the hook 42 is connected to the ear piece 44. At this time, the screw 37 needs to be rotated as needed to adjust the relative position of the ear piece 44. After the connection is completed, the relative position of the four ear pieces 44 needs to be checked again. Through the coordination and adjustment of the four screws 37, the coil 41 is roughly located directly below the core shaft 31 to avoid the center of gravity deviation and accidents during the lifting process. At this time, only rough adjustment is needed to achieve basic balance. The motor on the second mounting plate 24 is started to drive the reel 27 to rotate and pull the coil 41 upward. Since it is impossible to ensure that the axis of the core shaft 31 is completely consistent with the axis of the coil 41 at this time, on the one hand, the height of the coil 41 is increased, and on the other hand, the use of a soft connection to pull can well adapt to the process of pulling the coil 41 from the ground or platform. Until the core shaft 31 enters the bottom of the lifting part 20 and stops pulling the rope 28, at this time, tighten the screws on the four threaded bosses 26 to form a relatively fixed connection between the coil 41 and the lifting part 20, move the entire sling to above the core column of the iron core, start the motor on the first mounting plate 14, and drive the lifting part 20 downward through the combination of the active gear 17 and the ring gear 25. The descending movement at this time is a stable descent. During the descent, it is necessary to pay close attention to the relative position of the coil and the iron core. If necessary, adjust the screws on the four threaded bosses 26 to fine-tune the position of the coil 41 so that its position relative to the core column remains correct. Subsequently, the coil 41 is lowered through the transmission combination of the active gear 17 and the ring gear 25. Since the descent process is a hard-connected stable descent, the coil 41 will not shake laterally during the process, so that the risk of collision between the coil and the iron core is effectively controlled.
