Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of transformer production, and in particular relates to a slip-type transformer coil standing device. Background Art
[0002] The coil is a key component of transformer products. When winding the coil, it is usually produced in a lying position for ease of operation. After production is completed, the coil in the lying position needs to be adjusted to a standing position. This operation is called coil standing operation in the field of transformer production. For the coils of large transformer products, the coil standing operation obviously cannot be completed by manual means alone, and requires the help of a hoist. Using a hoist to complete the coil standing operation is also a very common method in the industry. However, when only using a hoist to pull the coil to stand, there will be a certain displacement difference between the bracket where the coil is located, the ground, and the lateral position of the hoist. During the coil standing operation, the coil may slip. This phenomenon poses a serious safety hazard during the entire operation. Therefore, it is necessary to improve the equipment to improve the safety of this link. Summary of the Invention
[0003] The present invention provides a sliding transformer coil standing device to solve the problems in the above-mentioned background technology.

[0021] 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.
[0022] See also Figure 1-Figure 3 The sliding transformer coil erecting device shown includes a base portion 10, a sliding portion 20, a flip portion 30 and a support portion 40. The sliding portion 20 is installed in the base portion 10, the sliding portion 20 is hinged upward to the flip portion 30, and the support portion 40 is installed in the middle of the flip portion 30.
[0023] The base 10 includes a base 11, a chute 12, a clamping plate 13, a pressure plate 14, a bolt 15, and a nut 16. The base 11 is part of the ground. In order to improve the overall strength, the base 11 can be two steel rails buried in the ground. The base 11 has a pair of chute 12, one on each side of the flip portion 30. The base 11 is provided with a chute 12, and the sliding portion 20 is installed in the chute 12. The end of the chute 12 is embedded in the clamping plate 13, and the clamping plate 13 extends upward from the bolt 15. The pressure plate 14 is fitted on the bolt 15. The pressure plate 14 is located on the base 11, and the nut 16 is installed on the bolt 15. The nut 16 presses the pressure plate 14 against the base 11 and tightens the clamping plate 13. The clamping plate 13 limits the sliding limit position of the sliding portion 20 to prevent the entire device from accidentally sliding beyond the chute 12 and causing a dangerous accident.
[0024] The sliding portion 20 includes an ear plate 21, a limiting plate 22, two ears 23 and a pulley 24. The ear plate 21 is located on the limiting plate 22. The limiting plate 22 has two ears 23 at the bottom. The pulley 24 is hinged in the middle of the two ears 23. In order to improve stability, there is a pair of two ears 23, and a pulley 24 is hinged in the middle of each pair of two ears 23. The limiting plate 22 is slidably fitted in the slide groove 12, and the ear plate 21 passes through the base 11 upward from the inside of the slide groove 12. The ear plate 21 is hinged upward to the flip portion 30.
[0025] The flip part 30 includes a flip plate 31, a hinge shaft 32, an inner toothed disc 33, a support shaft 34, a limit pin 35, a hanging ear 36 and a reinforcing rib 37. The flip plate 31 is an L-shaped folding plate. The coil to be stood up is placed on the flip plate 31. The coil can also be manufactured directly on the flip plate 31. In addition, the coil to be stood up needs to be tied and fixed to the flip plate 31. There is a hinge shaft 32 at each end of the bottom corner of the flip plate 31. The hinge shaft 32 is hinged to the ear plate 21 of the sliding part 20. There is an inner toothed disc 33 on each side of the middle of the flip plate 31. The support shaft 34 extends outward from the center of the inner toothed disc 33. The support part 40 is hingedly installed on the support shaft 34. A limit pin 35 is installed at the outer end of the support shaft 34. The limit pin 35 limits the movable position of the support part 40. The front end of the flip plate 31 has a pair of lugs 36 that connect upward to the hooks of the sling or the adapter beam. This configuration ensures stability during the lifting process. Reinforcement ribs 37 are evenly distributed on the bottom of the flip plate 31, enhancing the overall strength and rigidity of the flip portion 30.
[0026] The support portion 40 includes an outer chainring 41, a support rod 42, a roller 43, and a spring 44. The outer chainring 41 and the inner chainring 33 of the flip portion 30 are meshed and driven. The outer chainring 41 and the inner chainring 33 rotate in one direction relative to each other, and the direction of the one-way rotation is that the flip plate 31 rotates upward while the support portion 40 rotates downward, and cannot rotate in the opposite direction. The outer chainring 41 is hinged on the support shaft 34. The outer chainring 41 is connected to the support rod 42. The lower end of the support rod 42 is hinged to the roller 43. The roller 43 is a double-sided roller to improve the stability of the support. A spring 44 is installed on the support shaft 34 and is located between the limit pin 35 and the outer chainring 41. Under the action of the spring 44, the outer chainring 41 always has a tendency to stick to the inner chainring 33. The spring 44 is compressed only when the inner chainring 33 rotates relative to each other. Of course, the elastic coefficient of the spring 44 and the self-weight rotation torque of the support part 40 need to match each other. The self-weight rotation torque of the support part 40 acting on the outer chainring 41 should be able to push the outer chainring 41 to compress the spring 44. At the same time, the pressure provided by the spring 44 should be able to push the outer chainring 41 toward the inner chainring 33. In addition, due to the tooth profile of the inner and outer chainrings (as can be seen in the attached figure), the unidirectional rotation of the inner and outer chainrings rotates along the tooth profile at an inclined angle, which can alleviate the pressure on the spring.
[0027] The working principle of the present invention is as follows: First, the flip plate 31 is in the prone position as shown in the accompanying drawings. After the coil is manufactured on the flip plate 31 and secured with the necessary lashing, the lifting operation can begin. Before starting the lifting operation, the installation position and fixation of the clamping plate 31 and the pressure plate 14 must be checked to ensure that the clamping plate 13 and the pressure plate 14 are securely fixed in place. In the event of an accident during the lifting operation, the clamping plate 13 can act as a protective limiter for the entire device, preventing the flip portion 30 from accidentally sliding excessively and causing injury to nearby operators. The hook or hanging beam of the sling is connected to the hanging ear 36, and the front end of the flip portion 30 is slowly lifted. At this time, as the flip portion 30 gradually tilts upward, the sliding portion 20 slides within the chute 12 according to the positional relationship, providing height compensation. The entire lifting process does not require the sling to be moved; the sling can be fixed in a fixed position and the hook or hanging beam can be slowly reeled upward. As the flip portion 30 gradually tilts, the support portion 40 gradually rotates, providing auxiliary support for the flip portion 30 to prevent accidents during the lifting process. When the entire device is in the standing state, the turning part 30 is fixed to the chute 12 and the base part 11 as necessary, and the hook or the hanging beam can be removed, and the coil standing operation is completed.
[0028] The above embodiments primarily illustrate the present invention's coil erector for a sliding transformer. While only a limited number of embodiments and technical features have been described, those skilled in the art will appreciate that the present invention may be embodied in numerous other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are to be considered illustrative rather than restrictive, and the present invention is susceptible to various modifications and alternatives without departing from the spirit and scope of the present invention as defined in the appended claims.
