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 is to put the coil on the corresponding core column of the iron core. For transformer coils with slightly larger capacity, a hoist is needed to complete this operation. The core requirement of this operation for the hoist and the operator is stability. On the one hand, the installation position of the coil and the iron core must be accurate. On the other hand, the coil and the iron core must not collide. There are many kinds of hoists currently used in production sites, but most of them have one thing in common, that 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 of the coil, and the operator needs to monitor closely to ensure that there is no excessive lateral shaking during the downward movement of the coil on the core column. In order to complete this operation, it is usually required that multiple experienced and capable personnel perform the operation. Even so, the operation still has safety hazards. If you are not careful, it may cause damage to the coil or the 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: A coil-set hard-connected sling comprises a supporting part, a lifting part, a transition part and a working part.

[0010] Furthermore, the hook and the coil are bundled and wrapped with a tape to ensure a stable connection.

[0011] The beneficial effects of the present invention are: The present invention is used for the coil and core column set operation during the production of transformer box bodies. 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

DETAILED DESCRIPTION

[0013] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0014] See also Figure 1-Figure 3 The coil-set hard-connected hanger shown includes a supporting portion 10, a lifting portion 20, a connecting portion 30 and a working portion 40. The lifting portion 20 is installed on the supporting portion 10, the connecting portion 30 is installed at the bottom of the lifting portion 20, and the working portion 40 is connected to the bottom of the connecting portion 30.

[0015] The support part 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 two crossbars that are separated from each other. The support 11 supports the entire device on the ground. If necessary, a roller is installed at the bottom of the support 11 to facilitate the transfer of the entire sling. The support 11 has a column 12, 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 has a lifting part 20. The front part of the crossbeam 13 near the sleeve 16 has a hinged boss 15, and the driving gear 17 is hingedly installed in the hinged boss 15. The rear side of the hinged boss 15 has a first mounting plate 14, and a motor is installed on the first mounting plate 14 to drive the driving gear 17 to rotate.

[0016] 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 at the top center, and a side plate 23 is provided 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 meshed 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 bosses 26 for fine-tuning the position of the adapter 30. The side of the top plate 21 has a second mounting plate 24, and another motor is installed on the second mounting plate 24 to drive the reel 27 to rotate, thereby lifting the adapter 30 and the working part 40.

[0017] The adapter part 30 includes a core shaft 31, a center disk 32, a guide rail 33, a hanging ear 34, a rib plate 35, a lifting ring 36 and a screw rod 37. The core shaft 31 has a lifting ring 36 on the top, and the lifting ring 36 is connected to the rope 28. The core shaft 31 has a center disk 32 at the bottom, and the bottom of the center disk 32 has four evenly distributed guide rails 33. The front and rear ends of the guide rails 33 each have a hanging ear 34, and the screw rod 37 is hinged between the hanging ears 34. There are rib plates 35 between the core shaft 31, the center disk 32 and the guide rail 33. The rib plates 35 reinforce the overall structural strength of the adapter part 30 to ensure that the structure is safe and reliable.

[0018] The working part 40 includes a coil 41, a hook 42, a strap 43, an ear piece 44 and a slider 45. The coil 41 is hung from the bottom by four evenly distributed hooks 42 on all sides. The hook 42 and the coil 42 are bundled and wrapped with the strap 43 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 installed in a sleeve inside the guide rail 33. The center of the slider 45 has a threaded hole and is threadedly connected to the screw 37 to achieve the installation of the working part 40 and the adapter part 30.

[0019] The working principle of the present invention is: 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 strap 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 coordinated adjustment of the four screws 37, the coil 41 is roughly located directly below the core shaft 31 to avoid accidents during the hoisting process due to deviation of the center of gravity. 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 soft connection lifting can well adapt to the process of pulling the coil 41 upward 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.
