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, the coil in the lying position needs to be adjusted to a standing position. This operation is called coil standing operation in the transformer production field. For the coils of large transformer products, the coil standing operation obviously cannot be completed only by manual means, and requires the use 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 up, 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 slip-type transformer coil erecting device to solve the above-mentioned problems in the background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A slip-type transformer coil erecting device comprises a base part, a slip part, a flip part and a support part. The slip part is installed in the base part, the slip part is hinged to the flip part upwards, and the support part is installed in the middle of the flip part.

[0005] The base part includes a base, a slide groove, a clamping plate, a pressure plate, bolts and nuts. The base is part of the ground. The base has a pair of slide grooves, which are respectively located on both sides of the flip part. A slide groove is opened on the base, and the sliding part is installed in the slide groove. The sliding part includes an ear plate, a limit plate, two ears and a pulley. The ear plate is located on the limit plate. The limit plate has two ears at the bottom. The pulley is hinged in the middle of the two ears. The ear plate passes through the base upward from the inside of the slide groove, and the ear plate is hinged to the flip part upward. The flip part includes a flip plate, a hinge shaft, an inner tooth plate, and a support shaft. The flip plate is an L-shaped folding plate, and the coil to be stood up is placed on the flip plate. There is a hinge shaft at each end of the bottom of the corner point of the flip plate, and the hinge shaft is hinged to the ear plate of the sliding part. There is an inner tooth plate on each side of the middle of the flip plate, and a support shaft extends outward from the center of the inner tooth plate. The support part is hingedly installed on the support shaft. The supporting part includes an outer toothed disc, a support rod, a roller and a spring. The outer toothed disc and the inner toothed disc of the flip part are meshed and transmitted with each other. The outer toothed disc is hinged on the supporting shaft. The outer toothed disc is connected to the support rod. A spring is installed on the supporting shaft. The spring is located between the limit pin and the outer toothed disc.

[0006] Furthermore, in order to improve the overall strength, the base may be two steel rails buried in the ground.

[0007] Furthermore, a card plate is embedded in the end of the slide groove, and bolts are extended upward from the card plate. A pressure plate is installed on the bolt. The pressure plate is located on the base, and nuts are installed on the bolts. The nuts press the pressure plate against the base and tighten the card plate. The card plate limits the extreme position of the sliding of the sliding part to prevent the entire device from accidentally sliding beyond the slide groove and causing a dangerous accident.

[0008] Furthermore, in order to improve stability, the ears are provided in a pair, a pulley is hinged in the middle of each pair of ears, and the limit plate is slidably fitted in the slide groove.

[0009] Furthermore, a limit pin is installed at the outer end of the support shaft, and the limit pin limits the movable position of the support part.

[0010] Furthermore, the front end of the flip plate is provided with a pair of hanging ears, which are upwardly connected to the hooks of the sling or the transfer hanging beams. The configuration of the pair of hanging ears can better ensure the stability of the lifting process.

[0011] Furthermore, reinforcing ribs are evenly distributed on the bottom of the flip plate, and the reinforcing ribs enhance the overall strength and rigidity of the flip part.

[0012] Furthermore, the outer toothed disc and the inner toothed disc rotate unidirectionally relative to each other, and the direction of the unidirectional rotation is that the flip plate rotates upward while the support portion rotates downward, and they cannot rotate in the opposite direction.

[0013] Furthermore, the lower end of the support rod is hinged to the roller, and the roller is a double-sided roller to improve the stability of the support.

[0014] The beneficial effects of the present invention are: The present invention is used for the coil standing operation during the production of transformer boxes.

DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-Figure 3 The sliding transformer coil erecting device shown comprises a base part 10, a sliding part 20, a flip part 30 and a support part 40. The sliding part 20 is installed in the base part 10, the sliding part 20 is hinged to the flip part 30 upwards, and the support part 40 is installed in the middle of the flip part 30.

[0018] The base part 10 includes a base 11, a slide 12, a clamping plate 13, a pressure plate 14, a bolt 15 and a nut 16. The base 11 is a 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 rails, which are respectively located on both sides of the flip part 30. The slide 12 is opened on the base 11, and the sliding part 20 is installed in the slide 12. The end of the slide 12 is embedded in the clamping plate 13, and the clamping plate 13 extends upwardly from the bolt 15. The pressure plate 14 is installed on the bolt 15. The pressure plate 14 is located on the base 11. The nut 16 is installed on the bolt 15. The nut 16 presses the pressure plate 14 on the base 11 and tightens the clamping plate 13. The clamping plate 13 limits the sliding limit position of the sliding part 20 to prevent the entire device from accidentally sliding beyond the slide 12 and causing a dangerous accident.

[0019] The sliding portion 20 includes an ear plate 21, a limit plate 22, two ears 23 and a pulley 24. The ear plate 21 is located on the limit plate 22. The limit 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, the two ears 23 are provided in a pair, and a pulley 24 is hinged in the middle of each pair of ears 23. The limit 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 to the flip portion 30 upward.

[0020] The flip part 30 includes a flip plate 31, a hinge shaft 32, an inner tooth plate 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 folded plate. The coil to be erected 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 erected needs to be bound and fixed to the flip plate 31. The bottom ends of the corners of the flip plate 31 each have a hinge shaft 32, and the hinge shaft 32 is hinged to the ear plate 21 of the sliding part 20. The middle of the flip plate 31 has an inner tooth plate 33 on both sides, and the support shaft 34 extends outward from the center of the inner tooth plate 33. The support part 40 is hingedly installed on the support shaft 34. The limit pin 35 is installed at the outer end of the support shaft 34, and 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 hanging ears 36, which are connected to the hook of the sling or the transfer hanging beam upwards. The configuration of a pair of hanging ears can better ensure the stability of the lifting process. The bottom of the flip plate 31 is evenly distributed with reinforcing ribs 37, which enhance the overall strength and rigidity of the flip part 30.

[0021] The support part 40 includes an outer toothed disc 41, a support rod 42, a roller 43 and a spring 44. The outer toothed disc 41 and the inner toothed disc 33 of the flip part 30 are meshed and transmitted with each other. The outer toothed disc 41 and the inner toothed disc 33 rotate one-way with each other, and the direction of the one-way rotation is that the flip plate 31 rotates upward while the support part 40 rotates downward, and cannot rotate in the opposite direction. The outer toothed disc 41 is hinged on the support shaft 34, and the outer toothed disc 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. The spring 44 is sleeved and installed on the support shaft 34. The spring 44 is located between the limit pin 35 and the outer toothed disc 41. Under the action of the spring 44, the outer toothed disc 41 always has a tendency to be close to the inner toothed disc 33. Only when the two rotate with each other, the spring 44 is compressed. 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.

[0022] The working principle of the present invention is as follows: first, the flip plate 31 is in the lying position shown in the accompanying drawings. After the coil is manufactured on the flip plate 31, it can be tied and fixed after necessary binding before the standing operation can be started. Before starting the standing operation, it is necessary to check the installation position and fixing condition of the card plate 31 and the pressure plate 14 to ensure that the card plate 13 and the pressure plate 14 are firmly fixed in the appropriate position. When an accident occurs in the standing operation, the card plate 13 can play a role of limiting protection for the entire device to prevent the flip part 30 from accidentally sliding excessively and causing harm to the surrounding operators. Connect the hook or hanging beam of the sling with the hanging ear 36, and slowly pull the front end of the flip part 30. At this time, while the flip part 30 gradually flips upward, the sliding part 20 slides in the slide groove 12 according to the position relationship, playing a role of height compensation. The entire lifting process does not require the sling to shift. The sling can be fixed in a fixed position, and the hook or hanging beam can be slowly rolled up. In the process of the gradual flipping of the flip part 30, the support part 40 gradually rotates accordingly, playing a role of auxiliary support for the flip part 30 to prevent accidents during the lifting process. When the whole device reaches the standing state, the turning part 30 is fixed on the slide groove 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.

[0023] The above embodiments mainly illustrate the slip-type transformer coil erector of the present invention. Although only limited embodiments and technical features are described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its spirit and scope. Therefore, the embodiments shown are regarded as illustrative rather than restrictive, and the present invention may cover various modifications and replacements without departing from the spirit and scope of the present invention as defined in the appended claims.
