[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] In the existing technology, before hoisting, the coil 400 is placed on a wooden frame 500, with a gap between the bottom of the wooden frame 500 and the coil 400. The copper busbar needs to be smaller than the air duct hole of the coil 400. During hoisting, the copper busbar needs to be inserted into the air duct hole of the coil 400 first, and then the bolt is screwed to the lower end of the copper busbar. The bolt is installed between the bottom side of the coil 400 and the wooden frame 500. It is difficult for workers to observe the bolt installation process and cannot accurately judge the length of the bolt passing through the copper busbar. When the workers installing the bolt are negligent, other workers cannot observe the installation of the bolt, and it is very likely that the bolt will not pass through the copper busbar long enough, which may cause the coil 400 to fall in the air and cause a safety accident.

[0028] Reference Figures 1 to 3 According to an embodiment of the present invention, a transformer coil hoisting device includes at least two sets of hoisting frames 100. All the hoisting frames 100 enclose a hoisting space 300 for accommodating a coil 400. Each hoisting frame 100 includes a hoisting component 110, a first support plate 120, and a locking module 130. One end of the hoisting component 110 is provided with an insertion hole 111, and the other end is provided with a lifting device connecting structure. The lifting device connecting structure is located near the top of the hoisting space 300, and the insertion hole 111 is located near the bottom of the hoisting space 300. A support plate 120 is slidably mounted on the socket 111. One end of the first support plate 120 slides to the bottom side of the lifting space 300, and the other end is located on the side of the lifting member 110 away from the lifting space 300. The first support plate 120 has a support plane 121 facing the lifting space 300. The first support plate 120 is used to support the coil 400. A locking module 130 is disposed between the first support plate 120 and the lifting member 110. The locking module 130 is used to lock the lifting member 110.

[0029] The transformer coil hoisting device provided by this utility model uses at least two sets of hoisting frames 100 to hoist the transformer coil 400. The coil 400 is located within the hoisting space 300 enclosed by all the hoisting frames 100. Compared with the prior art method of supporting the bottom of the coil 400 with bolts, in this utility model, the hoisting frame 100 supports the coil 400 through the support plane 121 on the first support plate 120. The support plane 121 and the bottom of the coil 400 are in surface contact, which can better support the coil 400 and reduce damage to the bottom of the coil 400. In addition, each lifting frame 100 is located outside the coil 400 and does not need to pass through the air duct hole on the coil 400, which facilitates the arrangement of the lifting frame 100. The size of the lifting frame 100 is not limited by the air duct hole of the coil 400, and the assembly of the lifting frame 100 is completed before lifting the coil 400. This allows the staff to adjust and check the length of the first support plate 120 extending into the lifting space 300 from outside the coil 400, thereby preventing the first support plate 120 from being insufficiently extended into the lifting space 300 due to the negligence of the staff, avoiding the safety accident of the coil 400 falling, and ensuring construction safety.

[0030] Reference Figures 1 to 3 According to some embodiments of this utility model, the lifting component 110 is connected to a second support plate 140, which is located on the side of the first support plate 120 away from the lifting device connection structure, and the second support plate 140 abuts against the first support plate 120. Thus, the lifting component 110 supports the first support plate 120 through the second support plate 140, thereby improving its load-bearing capacity.

[0031] Reference Figures 1 to 3 According to some embodiments of this utility model, the locking module 130 includes a mounting plate 131 and a locking bolt 132. The mounting plate 131 is fixedly connected to the lifting member 110 and is located on the side of the first support plate 120 near the lifting device connection structure. The locking bolt 132 passes through and is screwed to the mounting plate 131, and abuts against the first support plate 120. The locking bolt 132 and the second support plate 140 cooperate to clamp and fix the first support plate 120. With the above configuration, the locking module 130 can reliably fix the first support plate 120, and the locking module 130 has a simple structure and is easy to operate.

[0032] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the lifting component 110 is set as a channel steel. The lifting component 110 is a general-purpose component that can be directly selected and purchased, making procurement convenient. Other components such as the first support plate 120, the second support plate 140, and the mounting plate 131 are also simple and readily available. As a result, the entire transformer coil hoisting device is easy to produce and has low cost.

[0033] Reference Figure 1 and Figure 2 A first reinforcing plate 150 is welded between the two opposite channel walls of the channel steel to improve the structural strength of the lifting component 110.

[0034] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the insertion hole 111 is formed on the bottom wall of the channel steel, and the mounting plate 131 and the second support plate 140 are inserted into the channel steel. With the above arrangement, the mounting plate 131 and the second support plate 140 are easy to install.

[0035] According to some embodiments of the present invention, the mounting plate 131 is welded to the channel steel, and the second support plate 140 is welded to the channel steel. This facilitates the installation of the mounting plate 131 and the second support plate 140, and the mounting plate 131 and the second support plate 140 can also be used to improve the strength of the channel steel.

[0036] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the lifting device connection structure is set as a first lifting hole 112. Thus, the lifting device of the crane is attached to the first lifting hole 112 by a hook or rope for easy lifting.

[0037] Reference Figure 1 , Figure 2 and Figure 4 According to some embodiments of the present invention, the first lifting hole 112 is opened on the bottom wall of the channel steel, and a second reinforcing plate 160 is welded to the bottom wall of the channel steel. The second reinforcing plate 160 is located at the first lifting hole 112, and the second reinforcing plate 160 has a second lifting hole 161. The second lifting hole 161 is connected to the first lifting hole 112. Through the above arrangement, the structural strength at the first lifting hole 112 can be enhanced, and the load-bearing capacity of the lifting component 110 can be improved.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the first support plate 120 has a storage hole 122, which is located on the side of the lifting member 110 away from the lifting space 300. The first support plate 120 can be suspended on the storage rack through the storage hole 122 for convenient storage and preservation.

[0039] Reference Figure 3 and Figure 4According to some embodiments of this utility model, the transformer coil hoisting device further includes a restraining rope 200, which is used to restrain all the lifting components 110 around the lifting space 300. In specific implementation, two or more lifting frames 100 are arranged around the coil 400, and one end of the first support plate 120 of the lifting frame 100 is inserted into the lower side of the coil 400. Then, the restraining rope 200 is used to restrain each lifting frame 100 to the coil 400. The lifting device of the crane can connect each lifting frame 100 through the first lifting hole 112. During the process of hoisting the coil 400, the restraining rope 200 can prevent the lifting frames 100 from opening outward and causing the coil 400 to fall.

[0040] It should be noted that in other embodiments, the above-mentioned lifting device connection structure may also adopt other configuration methods. For example, the lifting device connection structure may include threaded fasteners, and the lifting component 110 is detachably fixed to the lifting device of the crane by the threaded fasteners. In this case, it is not necessary to set the restraint rope 200.

[0041] It is conceivable that in some other embodiments, the first support plates 120 of the two opposing lifting frames 100 can be connected as one unit, thereby eliminating the need for the restraint rope 200.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
