Description

Technical Field

[0001] This utility model relates to the technical field of hydropower construction and transportation equipment, specifically to a prefabricated substation mobile device. Background Technology

[0002] Prefabricated substations (hereinafter referred to as "panel substations") are compact, complete sets of power distribution equipment that integrate high-voltage switches, transformers, and low-voltage distribution panels. Due to their compact structure, small footprint, and ease of installation, they are widely used in power systems. In the manufacturing process of panel substations, the finished product after assembly and testing typically weighs several tons or even tens of tons. Moving such heavy panel substations from the production line to the storage or shipping area is a crucial and technically challenging step in the manufacturing process.

[0003] Currently, overhead cranes are commonly used for transportation. However, small and medium-sized factories typically lack the space to install large-tonnage overhead cranes. When the weight of the transformer exceeds the rated load of the existing crane, lifting operations become impossible. Replacing the crane with a larger one or reinforcing the factory building is costly and complex. Some manufacturers use external cranes for transport, but these are bulky and difficult to operate in limited factory space, and their rental costs are high and efficiency is low.

The driven mechanism includes two parallel driven tank vehicles, with a load-bearing beam fixedly installed between the two driven tank vehicles; The load-bearing mechanism includes a load-bearing frame for placing the prefabricated substation and multiple horizontal and vertical bars installed within the load-bearing frame. One side of the load-bearing frame is installed in the first limiting groove, and the other side is installed on the load-bearing beam. The load-bearing frame is also equipped with multiple connecting components for fixing the prefabricated substation.

[0006] A further technical solution is: multiple vertical bars are welded at equal intervals between the long sides of the load-bearing frame, and multiple horizontal bars are welded at equal intervals between adjacent vertical bars and between the vertical bars and the short sides of the load-bearing frame.

[0007] A further technical solution is to weld and fix reinforcing members at the connection nodes of the four inner corners and the middle of the load-bearing frame.

[0008] A further technical solution is to symmetrically install multiple lifting lugs on both sides of the load-bearing frame.

[0009] A further technical solution is as follows: The connecting assembly includes four mounting plates symmetrically arranged at the bottom of both sides of the prefabricated substation shell. The mounting plates are provided with a first adjustment hole, which is an oblong hole extending along the long side of the load-bearing frame. The two ends of the short side of the load-bearing frame are provided with L-shaped connecting plates corresponding to the mounting plates. The connecting plates are provided with connecting holes on their sides. After the connecting holes are aligned with the first adjustment holes, they are fastened together by a first bolt assembly. The bottom edge of the connecting plate is adjustablely connected to the top surface of the load-bearing frame along the short side of the load-bearing frame.

[0010] A further technical solution is: fixing holes are symmetrically provided at both ends of the top surface of the short side of the load-bearing frame, and a second adjustment hole is opened on the bottom edge of the connecting plate. The second adjustment hole is an oblong hole extending along the short side of the load-bearing frame. After the fixing hole and the second adjustment hole are aligned, they are fastened together by the second bolt assembly.

[0011] A further technical solution is: two corresponding second limiting grooves are provided on both sides of the turntable of each driven tank vehicle.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] A prefabricated mobile substation device, such as Figures 1-11 As shown, it includes a drive mechanism 1, a driven mechanism 2, and a load-bearing mechanism 3.

[0023] The drive mechanism 1 includes a drive tank 11, and a first limiting groove 12 is provided on the turntable 111 of the drive tank. Preferably, in order to ensure that the load frame 31 can be smoothly positioned during lifting, the width of the first limiting groove 12 is designed to be slightly larger than the cross-sectional dimension of the load frame 31, so as to provide necessary buffer clearance for the tilting and swaying of the load frame 31 during the placement process, reduce the installation difficulty, and improve the work efficiency.

[0024] The driven mechanism 2 includes two parallel driven tank vehicles 21, with a load-bearing beam 23 fixedly installed between the two driven tank vehicles 21.

[0025] The load-bearing mechanism 3 includes a load-bearing frame 31 for placing the prefabricated substation 4 and multiple horizontal bars 32 and vertical bars 33 vertically arranged in the load-bearing frame 31. One side of the load-bearing frame 31 is installed in the first limiting groove 12, and the other side is installed on the load-bearing beam 23. The load-bearing frame 31 is provided with multiple connection components 36 for fixing and connecting the prefabricated substation (hereinafter referred to as the prefabricated substation).

[0026] The driving tank vehicle 11 is an electrically powered transport tank vehicle with a remote control module, while the driven tank vehicle 21 is a transport tank vehicle without a power system. All tank vehicles used in this application are existing products from the prior art, and their implementation principles will not be elaborated here. The load capacity of the tank vehicle is selected based on the weight of the transformer substation; typically, a heavy-duty 24-ton transport tank vehicle can be chosen. Furthermore, the driving tank vehicle can be selected as a steering or straight-moving transport tank vehicle according to the needs of the movement path within the factory.

[0027] Because of the built-in power module of the driving tank vehicle 11, the height of the driving tank vehicle 11 is generally higher than that of the unpowered driven tank vehicle 21. The load-bearing beam 23 on the driven tank vehicle 21 can raise the connection point of the driven tank vehicle 21, and together with the driving tank vehicle 11, they can support a horizontal load-bearing platform, which facilitates the placement of the load-bearing frame 31 and ensures the force balance of the load-bearing frame 31 and the transformer box 4.

[0028] The load-bearing frame 31 is welded together from mutually perpendicular long sides 311 and short sides 312. In one embodiment, the load-bearing frame 31 is formed by welding two channel steel ends together to form the long side 311 or the short side 312, and then welding them end to end to form a square frame. In other embodiments, the load-bearing frame 31 is formed by welding square tubes end to end.

[0029] Multiple vertical bars 33 are welded at equal intervals between the long sides 311 of the load-bearing frame, and multiple horizontal bars 32 are welded at equal intervals between adjacent vertical bars 33 and between the vertical bars 33 and the short sides 312 of the load-bearing frame. The horizontal bars 32 and vertical bars 33 within the load-bearing frame 31 are arranged at equal intervals, and are welded and fixed to the load-bearing frame 31, serving as the foundation for bearing heavy loads and improving the overall strength of the load-bearing mechanism 3. Specifically, the vertical bars 33 are made of #8 channel steel, and the horizontal bars 32 are made of 60*60mm square tubing.

[0030] The load-bearing frame 31 has reinforcement members 34 welded and fixed at the four inner corners and the middle connection nodes. The reinforcement members 34 can be triangular plates or diagonal braces to improve the overall strength and stability of the load-bearing frame 31.

[0031] Multiple lifting lugs 35 are symmetrically arranged on both sides of the load-bearing frame 31. The lifting lugs 35 can be used to connect lifting equipment.

[0032] like Figures 4-6 As shown, the connecting assembly 36 includes mounting plates 361 symmetrically arranged at the bottom of both sides of the transformer substation housing 4. There are a total of four mounting plates 361. Each mounting plate 361 has a first adjustment hole 362, which is an oblong hole extending along the long side 311 of the load-bearing frame. Both ends of the short side 312 of the load-bearing frame are provided with L-shaped connecting plates 363 corresponding to the mounting plates 361. There are four connecting plates 363 corresponding to the mounting plates 361. Each connecting plate 363 includes mutually perpendicular side edges and bottom edges. A connecting hole 364 is provided on the side edge of the connecting plate 363. After the connecting hole 364 is aligned with the first adjustment hole 362, it is fastened by the first bolt assembly 366. The bottom edge of the connecting plate 363 is adjustablely connected to the top surface of the load-bearing frame 31 along the short side 312 of the load-bearing frame.

[0033] Four fixing holes are symmetrically arranged on the top surfaces of both ends of the short side 312 of the load-bearing frame. A second adjustment hole 365 is opened on the bottom edge of the connecting plate 363. The second adjustment hole 365 is an oblong hole extending along the direction of the short side 312 of the load-bearing frame. After the fixing holes are aligned with the second adjustment hole 365, they are fastened together by the second bolt assembly 367.

[0034] The first bolt assembly 366 includes a first bolt, a first washer, and a first nut, and the second bolt assembly 367 includes a second bolt, a second washer, and a second nut. Both the first bolt and the second bolt are high-strength bolts.

[0035] By setting the connecting component 36, it is convenient to fix the transformer substation 4 housing onto the load-bearing frame 31. The installation position of the transformer substation 4 housing relative to the connecting plate 363 can be finely adjusted through the first adjustment hole 362 on the mounting plate 361 to adapt to the positional deviation in the left and right (long side direction). The installation position of the connecting plate 363 itself on the load-bearing frame 31 can be finely adjusted through the second adjustment hole 365 on the bottom edge of the connecting plate 363 to adapt to the positional deviation in the front and back (short side direction). Even if there is a slight deviation in position when the transformer substation 4 housing is manually hoisted, there is no need to repeatedly lift and adjust, simplifying the installation process and improving installation efficiency.

[0036] like Figure 8 and Figure 9 As shown, each driven tank 21 has two corresponding second limiting grooves 22 on both sides of its turntable. The width of the second limiting grooves 22 is adapted to the cross-sectional dimensions of the load-bearing beam 23. Aligned through holes are provided on the side walls of the second limiting grooves 22 and the load-bearing beam 23, and the holes are connected by passing through the third bolt assembly 24 in sequence. The third bolt assembly 24 includes a third bolt, a third washer, and a third nut. The third bolt is a high-strength bolt. Specifically, the second limiting grooves 22 are symmetrically welded from two equal-length angle irons, and the bottom surfaces of the equal-length angle irons are welded and fixed to the top surface of the driven tank 21.

[0037] L-shaped positioning plates 25 are provided at both ends of the load-bearing beam 23. The positioning plates 25 include mutually perpendicular bottom edges and side edges. The bottom edges of the positioning plates 25 are fixedly connected to the load-bearing beam 23, and rubber pads 28 are provided on the side edges of the positioning plates 25. The transformer substation 4 and the load-bearing frame 31 are stably placed on the load-bearing beam 23 by their own weight, and the two sides of the load-bearing frame 31 are clamped by the rubber pads 28 of the two positioning plates 25, which further improves the stability of the load-bearing frame 31.

[0038] Preferably, the positioning plate 25 has a waist-shaped third adjustment hole 26 on its bottom edge. The third adjustment hole 26 is a waist-shaped hole extending along the length of the load-bearing beam 23. Mounting holes are respectively provided on the top surface of both ends of the load-bearing beam 23. After the third adjustment hole 26 of the positioning plate 25 is aligned with the mounting hole of the load-bearing beam 23, they are fastened together by the fourth bolt assembly 27. The fourth bolt assembly 27 includes a fourth bolt, a fourth washer, and a fourth nut. The fourth bolt is a high-strength bolt. During hoisting, there may be slight deviations in the placement position of the load-bearing frame 31 each time. By providing the waist-shaped third adjustment hole 26, it is convenient to adjust the installation position of the positioning plate 25 on the load-bearing beam 23 and adjust the distance between the side plates of the two positioning plates 25. Fine adjustments can be made according to the position of the load-bearing frame 31 placed on the load-bearing beam 23, making the operation more flexible and convenient.

[0039] The working process of the prefabricated substation mobile device in this application is as follows: 1. Assemble the load-bearing frame 31: Use an overhead crane inside the factory to lift the assembled load-bearing frame 31 onto the rubber mat on the factory floor.

[0040] 2. Assemble the driven mechanism 2: Place the left and right ends of the load-bearing beam 23 between the two second limit slots 22 on the upper surface of the two driven tanks 21. After adjusting the position of the load-bearing beam, install the fourth bolt assembly 27 to fix the load-bearing beam 23.

[0041] 3. Placement of the transformer substation 4 housing: After the transformer substation 4 housings arrive at the site, they will be hoisted onto the load-bearing frame 31 using a crane. The bottom of the transformer substation 4 housing will be fixed to the load-bearing frame 31 using the connecting assembly 36. One transformer substation 4 will be placed on one load-bearing frame 31.

[0042] 4. Moving the transformer substation 4 to the factory: After installing components and cabinets inside the transformer substation housing, and after this batch of transformer substation 4 has been debugged and meets the conditions for shipment, a crane in the factory is used to lift one side of the load-bearing frame 31, raising it a certain distance to accommodate the driven mechanism. The assembled driven mechanism 2 is pushed in, and temporary limiting components such as wedges or wooden blocks are used to block the wheels of the tank vehicle to prevent it from moving at the moment of contact with the heavy object. It is then slowly lowered so that one side of the load-bearing frame 31 is placed on the load-bearing beam 23 between the two driven tank vehicles 21.

[0043] Next, lift one side of the load-bearing frame 31 and raise it a certain distance to accommodate the drive mechanism. Remotely drive the tank 11 under the load-bearing frame 31 and adjust its position. Use temporary limiting components such as wedges or wooden blocks to block the tank's wheels front and rear to prevent it from moving upon contact with the load. Slowly lower the load-bearing frame 31 until it is placed in the first limiting groove 12 on the turntable of the drive tank 11. Adjust the installation position of the positioning plate 25 on the load-bearing beam 23 so that the positioning plate 25 is firmly pressed against both sides of the load-bearing frame 31.

[0044] The remote-controlled tank vehicle 11 slowly moves the transformer substation 4 to an outdoor gantry crane, removes the connecting components, and uses the gantry crane to lift the transformer substation 4 onto a transport vehicle for shipment.
