DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figs. 1-5 In the embodiments of the utility model, a pre-installed transformer substation comprises the pre-installed transformer substation 1 composed of a transformer substation box body 101 and a supporting base frame 102. The supporting base frame 102 is fixed to the bottom of the transformer substation box body 101. The two sides of the supporting base frame 102 are provided with overturning notches 103. The inside of the overturning notches 103 is provided with an auxiliary assembly 2. The auxiliary assembly 2 comprises a hoisting unit and a rolling unit. The hoisting unit is used for providing a hanging position for the hook of a hoisting device. The rolling unit is overturned downward by the pulling of the hoisting unit by the hoisting device. When the pre-installed transformer substation 1 is placed on a platform, the rolling unit is used for providing movement assistance for the orientation adjustment of the pre-installed transformer substation 1 by contacting the ground.

[0021] The hoisting unit comprises a fixed shaft 201, an L-shaped overturning arm 202 and a hanging pin 203. The fixed shaft 201 is fixed to the inside top of the overturning notch 103. The L-shaped overturning arm 202 is rotatably sleeved to the outside of the fixed shaft 201. The vertical part of the L-shaped overturning arm 202 is formed with a notch groove. The hanging pin 203 is fixed to the inside of the notch groove on the vertical part of the L-shaped overturning arm 202. The hook of the hoisting device is hung outside the hanging pin 203, so that the hoisting operation of the pre-installed transformer substation 1 is realized.

[0022] The rolling unit comprises a fixed plate 204, a rotating column 205, and a roller 206. The fixed plate 204 is fixed to one side of the horizontal part of the L-shaped turnover arm 202. The rotating column 205 is rotationally connected to the fixed plate 204 and extends to the inner side area of the support base 102. The roller 206 is rotationally connected to the side of the rotating column 205 away from the fixed plate 204.

[0023] When the hooks of the hoisting equipment pull the hanging pins 203, the L-shaped turnover arm 202 turns around the fixed shaft 201, so that the roller 206 turns downward. The roller 206 rolls on the platform to provide movement assistance for the orientation adjustment of the prefabricated transformer substation 1.

[0024] In the initial state of the L-shaped turnover arm 202, the vertical part, the horizontal part, and the fixed plate 204 of the L-shaped turnover arm 202 are accommodated inside the turnover notch 103, and the top of the roller 206 does not contact the bottom of the transformer substation box 101.

[0025] In this embodiment, it should be noted that the auxiliary assembly 2 is provided with four groups, and the four groups of auxiliary assemblies 2 are distributed in a matrix on the support base 102. In the daily state, the auxiliary assembly 2 is completely accommodated inside the rotating notch 103 and does not protrude. When the prefabricated transformer substation 1 needs to be hoisted and installed, the operation steps are as follows:

[0026] First, the four hooks of the hoisting equipment are respectively hooked with the hanging pins 203 on the four groups of auxiliary assemblies 2. Then, the hoisting equipment operates to pull the hooks against the hanging pins 203. At this time, the L-shaped turnover arm 202 is turned around the fixed shaft 201 under the tension. The hanging pin 203 is turned to the outside of the support base 102, so that the hook does not collide with the support base 102. In addition, the fixed plate 204, the rotating column 205, and the roller 206 are turned downward (it should be noted that in the daily state, the roller 206 is vertically distributed in the arc direction under the action of its own gravity, i.e., the rotating shaft of the roller 206 is parallel to the fixed shaft 201 and the hanging pin 203. During the downward turning of the roller 206, the arc surface of the roller 206 contacts the ground). Finally, the roller 206 protrudes below the support base 102 and contacts the ground. The bottom of the support base 102 is separated from the ground. Then, the hoisting equipment continues to operate to lift the device as a whole and transfer it to the pre-poured platform.

[0027] When the roller 206 contacts the platform, the operation of the hoisting device can be paused first, and then the orientation of the prefabricated substation 1 is adjusted manually. In this process, the roller 206 freely rolls along the edge of the platform, and most of the weight of the prefabricated substation 1 is borne by the hoisting device, so that the orientation of the prefabricated substation 1 can be easily adjusted. At the same time, due to the rolling resistance of the roller 206 and the platform, the prefabricated substation 1 has a certain moving resistance. When the orientation of the prefabricated substation 1 is determined, the prefabricated substation 1 can remain stable and immobile. Compared with the traditional suspended adjustment operation of the prefabricated substation, the orientation of the prefabricated substation 1 can be better controlled and positioned.

[0028] After the orientation of the prefabricated substation 1 is determined, the hoisting device can be started again to completely lower the prefabricated substation 1. At this time, the roller 206 is pressed upward to be turned and stored inside the support base 102, without affecting the contact between the support base 102 and the platform.

[0029] Please refer to Figs. 1-5 , the inner wall top of the turning groove 103 near the outer side of the support base 102 is an inclined surface, which is used to limit the turning angle of the L-shaped turning arm 202.

[0030] In this embodiment, the turning angle of the L-shaped turning arm 202 is less than ninety degrees when it is pulled to turn by the hook, so that the clamping angle between the rotating column 205 turned downward and the ground is less than ninety degrees. Therefore, when the prefabricated substation 1 is completely lowered, the roller 206 can be pressed upward to turn, without affecting the contact between the support base 102 and the platform.

[0031] It should be further pointed out that when the support base 102 contacts and fits the platform, the part of the L-shaped turning arm 202 contacting the hanging pin 203 has not been completely stored in the turning groove 103. Finally, the hook is manually removed, and the L-shaped turning arm 202 is pushed to be stored inside the turning groove 103. The L-shaped turning arm 202 and the turning groove 103 have friction, which can ensure the stability of the storage state of the L-shaped turning arm 202.

[0032] Please refer to Figs. 1-3 , the end face and the side face of the support base 102 are also provided with ventilation openings 104, which completely penetrate the two sides and two ends of the support base 102.

[0033] In this embodiment, the structure of the ventilation opening 104 is arranged to maintain good conduction between the inside space of the support base 102 and the external environment, so as to avoid water accumulation in the inside space of the support base 102.

[0034] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
