The length of the first sleeve 11241 is not fixed and can be processed according to actual on-site requirements; during use, the two ends of the second sleeve 11242 are respectively inserted into the bottom column 1122 and the middle column 1123, and staggered fixation is performed using the reserved through holes to prevent offset during use.

[0061] It should be noted that the specification of the adjusting seat 1124 is selected according to the height value to be adjusted. That is to say, the specifications of the adjusting seat 1124 are different, and the height of the first sleeve 11241 is different. The size of the first sleeve 11241 can be made according to the actual height.

[0062] In an implementable manner where the bottom column 1122, the middle column 1123, and the top column 1121 are all made of square steel, the first sleeve 11241 and the second sleeve 11242 are also both made of square steel.

[0063] It should be noted that the outer diameter dimension of the first sleeve 11241 is the same as the outer diameter dimensions of the bottom column 1122 and the middle column 1123, and the outer diameter dimension of the second sleeve 11242 is the same as the inner diameter dimensions of the bottom column 1122 and the middle column 1123.

[0064] Continue to refer to Figure 10, in this embodiment, the horizontal connecting seat 111 is made of an I-beam. A plurality of through holes 1111 are formed at the bottom end of the horizontal connecting seat 111. The through holes 1111 are arranged in one-to-one correspondence with the fixing holes 11212. The bottom end of the horizontal connecting seat 111 is bolted to the top plate 11211.

[0065] During use, one end of a bolt sequentially passes through the through hole 1111 and the fixing hole 11212 and is threadedly connected to a nut, so as to realize the fixed connection between the horizontal connecting seat 111 and the top plate 11211.

[0066] During span adjustment, the reserved through holes 1111 of the horizontal connecting seat 111 can adjust the base 21 of the track 20 according to the required span.

[0067] The construction process of the sliding device 1 provided in this embodiment is as follows: select the specification of the required adjusting seat 1124 according to the height of the installation room to adjust the height of the adjustable frame 10, so that the height of the adjustable frame 10 is adapted to the height of the installation room. Dock the sliding rail 22 with the transport track 20 in the installation room. Use an engineering vehicle to hoist a large transformer onto the sliding rail 22. Set two chain hoists in advance in the installation room. Hang the hook heads of the two chain hoists on both sides of the transformer respectively. The two chain hoists are stressed simultaneously to slide the transformer into the installation room.

[0068] The sliding device 1 provided in this application includes an adjustable frame 10 and two relatively arranged tracks 20; the bottom end of the adjustable frame 10 is fixed to the ground. The two tracks 20 are both arranged at the top end of the adjustable frame 10. The two tracks 20 both extend along the first direction 30 of the adjustable frame 10. The two tracks 20 are arranged at intervals along the second direction 40 of the adjustable frame 10. The track 20 is bolted to the top end of the adjustable frame 10. The transformer to be installed is located on the two tracks 20, and the transformer to be installed can slide along the track 20; compared with the traditional transportation of transformers, it saves manpower, and at the same time, improves the construction efficiency and safety.

[0069] The sliding device 1 provided by the present utility model has the following advantages: the device has a simple structure and is easy to manufacture, facilitating installation and operation. The connection form of each component is bolt connection, with rapid assembly and reusable, improving economic benefits.
