Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer installation support frame. Background Art

[0002] The transformer mounting bracket is a structure that supports the transformer, which mainly includes a pole body and a supporting structure. The supporting structure is installed between the two pole bodies, and the transformer box is stabilized between the two pole bodies by the support of the supporting structure. The transformer is generally composed of multiple parts, including the transformer box, lightning protection device, drop-out switch and disconnector. During installation, there are generally four groups of supporting structures installed between the two pole bodies from bottom to top. For the sake of convenience, the multiple supporting structures are named first, second, third and fourth according to their height. That is, the lowest support structure is the first support structure for installing the transformer box and the distribution box. The second support structure is higher than the first support structure by a certain distance and is used to install the lightning arrester. The third support structure is higher than the second support structure by a certain distance and is used to install the drop-out switch. The fourth support structure is higher than the third support structure by a certain distance and is used to install the disconnector. It can be seen that the existing transformer mounting bracket is arranged in layers, and the support structures on each layer are independent of each other and do not affect each other.

[0003] The problem with the existing technology is that the lowest support structure of the existing transformer mounting bracket, that is, the first support structure, bears the heaviest weight and is mainly used to support larger transformer boxes and distribution boxes, and bears a larger load. The second support structure is used to support small and lightweight lightning arresters, and bears a smaller load. Therefore, when the transformer mounting bracket is generally damaged, it is mostly the first support structure with a larger load-bearing capacity that is damaged. Based on the above situation, it is necessary to design a transformer mounting support frame to solve the above problem. Utility Model Content

[0004] The utility model provides a transformer mounting support frame, which connects a first supporting structure and a second supporting structure of the transformer mounting support frame through a suspension device, so that the second supporting structure can share part of the load-bearing load of the first supporting structure, thereby reducing the load-bearing load of the first supporting structure and improving its service life.

[0005] The technical problem solved by the present invention is achieved by the following technical solutions:

[0006] The utility model provides a transformer mounting support frame, comprising a first supporting structure for supporting a transformer box body, the first supporting structure comprising a first hoop arranged outside two electric pole bodies, two first supporting beams and four first locking screws; a second supporting structure for supporting a transformer lightning protection device, the second supporting structure comprising a second hoop arranged outside the two electric pole bodies, two second supporting beams and four second locking screws; the second supporting structure is connected to the first supporting structure through a suspension device, thereby increasing the bearing capacity of the first supporting structure.

[0007] Preferably, the suspension device is arranged on a first supporting beam and a second supporting beam corresponding to each other in upper and lower positions.

[0008] Preferably, the outer surfaces of the first hoop and the second hoop are provided with pull ears, and the suspension device is arranged on the first hoop and the second hoop at corresponding upper and lower positions through the pull ears.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] In order to enable those skilled in the art to better distinguish the difference between the present invention and the prior art, first refer to Figure 1 The prior art is described. The existing transformer mounting support frame includes two electric pole bodies 4 and multiple supporting structures ( Figure 1 Only two supporting structures are shown, namely the first supporting structure at the lower part and the second supporting structure at the higher part. However, the actual transformer mounting support frame generally has four supporting structures. From top to bottom, the first supporting structure is used to install the transformer box 8 and the distribution box 9, the second supporting structure is used to install the lightning protection device 10, the third supporting structure is used to install the drop-type switch, and the fourth supporting structure is used to install the disconnector. The improvement of the utility model only designs the first supporting structure and the second supporting structure, so Figure 1Only the first supporting structure and the second supporting structure are shown in the figure. The structures of the first supporting structure and the second supporting structure are basically the same, and both include two hoops (hereinafter referred to as the first hoop 1 and the second hoop 5) for hooping the outer surface of the two electric pole bodies 4, and two supporting beams (hereinafter referred to as the first supporting beam 2 and the second supporting beam 6) can be carried on the supporting ears of the hoops (not numbered in the figure), and four locking screws (hereinafter referred to as the first locking screw 3 and the second locking screw 7) are used to lock the two supporting beams to ensure that the supporting beams do not separate from the supporting ears of the hoops. The supporting structure composed of the two hoops, the two supporting beams and the four locking screws stably supports the various accessories of the transformer. Figure 1 It can also be observed that the first supporting structure at the lower part of the pole body 4 is used to support the transformer box 8, and a distribution box 9 is suspended at the bottom. The gravity load it carries is large and it is easy to be damaged, while the second supporting structure at the upper part of the pole body 4 is used to support the lightning protection device 10. The gravity load it carries is small and it is not easy to be damaged.

[0024] The position of the first supporting structure that is most prone to damage is the position where the hoop contacts the pole body 4. The traditional pole body 4 is a columnar body with a diameter that gradually decreases from bottom to top. When the hoop is set on the pole body 4, only the lower part of the inner wall of the hoop is in linear contact with the outer surface of the pole body 4. The stress at this position of the hoop is relatively large, and it is most likely to deform, resulting in deformation of the hoop, especially when the gravity load is large. The second supporting structure will not be damaged because the lightning protection device 10 it bears as a whole is relatively light. Based on the above situation, the utility model improves the existing transformer mounting bracket to avoid the problem of twisting and deformation of the hoop due to the large gravity on the first supporting structure.

[0025] refer to Figures 2 to 7 The main improvement of the present invention is that by arranging a suspension assembly between the first supporting structure and the second supporting structure, the second supporting structure can share part of the weight of the first supporting structure, so that the load-bearing effect of the first supporting structure is better, the bearing capacity of the first supporting structure is increased, and the first supporting structure is avoided from being damaged due to the large gravity. In order to distinguish the various components of the first supporting structure and the second supporting structure, the various components of the first supporting structure are named first hoop 1, first supporting beam 2 and first locking screw 3, and the various components of the second supporting structure are named second hoop 5, second supporting beam 6 and second locking screw 7.

[0026] refer to Figure 2 and Figure 3, is a schematic structural diagram of the first embodiment of the present invention, wherein the suspension device is provided on the first supporting beam 2 and the second supporting beam 6 corresponding to the upper and lower positions. The suspension device may adopt a pull rod 11 or other structures (the following embodiments may also adopt the pull rod 11). The pull rod 11 includes a suspension screw 1101 and a nut 1102. Figure 2 and Figure 3 In the figure, the second supporting beam 6 suspends the first supporting beam 2 through the pull rod 11, that is, the first supporting beam 2 and the second supporting beam 6 are provided with through holes (not numbered in the figure), and the pull rod 11 connects the first supporting beam 2 and the second supporting beam 6 through the through holes. Therefore, part of the gravity exerted on the first supporting beam 2 will be transmitted to the second supporting beam 6 through the pull rod 11, thereby achieving the effect that the second supporting structure shares the gravity borne by the first supporting structure, thereby avoiding that the gravity of the transformer and the distribution box 9 act on the first hoop 1, causing damage to the first hoop 1.

[0027] refer to Figure 4 and Figure 5 , is a structural diagram of the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the position of the suspension device is different. The suspension device of this embodiment is installed between the second hoop 5 and the first hoop 1. The first hoop 1 and the second hoop 5 are integrally formed with a pull ear portion 13, and the pull ear portion 13 is provided with a through hole (not numbered in the figure). When the first hoop 1 is subjected to a large tensile force, the first hoop 1 can apply tensile force to the second hoop 5 through the pull rod 11, thereby reducing the pressure on the first hoop 1 and avoiding deformation of the first hoop 1.

[0028] refer to Figure 6 , is a structural diagram of the third embodiment of the present utility model. The difference between this embodiment and the first and second embodiments is that the position of the suspension device is on the second hoop 5 and the first supporting beam 2, that is, the ends of the two first beams are fixed by a connecting plate 12, and a pull ear 13 is provided on the second hoop 5. The pull rod 11 connects the pull ear 13 and the connecting plate 12, so that the second supporting structure can share part of the bearing force of the first supporting structure, thereby avoiding the lower part of the inner wall of the first hoop 1 being subjected to a large force and causing damage.

[0029] Similarly, those skilled in the art can easily think of the fourth embodiment of the present utility model based on the third embodiment. The difference between this embodiment and the third embodiment is that the suspension device is installed on the second supporting beam 6 and the first hoop 1, that is, a connecting plate 12 is provided at the end of the two second supporting beams 6, and a pull ear 13 is provided on the outer surface of the first hoop 1. The pull rod 11 connects the connecting plate 12 and the pull ear 13, so that the second supporting structure shares the bearing force of the first supporting structure.

[0030] It should be further explained that although the pull rod 11 of the above-mentioned suspension device adopts a connection method of a straight suspension screw 1101 and a nut 1102, it is not limited to this method. For example, in actual process, it can also be designed to be connected by welding. Similarly, its installation angle is not limited to the vertical state. For example, it can also realize the suspension of the first support structure to the second support structure by the flat steel body by inclined welding, so that the second support structure can share the weight of the first support structure, avoiding the first support structure. The lower part of the inner wall of the first hoop 1 is subjected to a large extrusion force, which causes damage. Through the suspension device, the extrusion force of the lower part of the inner wall of the first hoop 1 by the pole body 4 can be shared to the inner wall of the second hoop 5.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
