Description
Technical Field
[0001] The utility model relates to the technical field of box-type substations, in particular to a towable substation. Background Art
[0002] A box-type substation, also called a prefabricated substation or a prefabricated transformer substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device. The box-type substation is applicable to mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil construction power distribution room and power distribution station and becomes a new type of complete set of power transformation and distribution devices. In order to facilitate movement, the box-type substation is usually installed on the towing chassis of a vehicle to meet the requirement that the box-type substation can quickly reach the installation site during emergency rescue.
[0003] At present, when the box-type substation is transported, it is usually lifted onto the transport truck by a crane, and then transported to the installation site by the truck over a long distance. After being transported to the installation site, it still needs to be lifted off the truck by a crane. However, in some occasions of short-distance transportation of the box-type substation, when it is still lifted by a crane and loaded and unloaded by a truck, the transportation cost is relatively high. Therefore, a towable substation is proposed now. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defect that in the prior art, in some occasions of short-distance transportation of the box-type substation, when it is still lifted by a crane and loaded and unloaded by a truck, the transportation cost is relatively high, and a towable substation is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A towable substation includes a box-type substation. A fixed chassis in a "return" shape is fixedly connected to the bottom of the box-type substation. Universal wheels for transporting the box-type substation are arranged below the fixed chassis in a uniformly distributed manner. L-shaped towing hooks are symmetrically and fixedly connected to one side of the fixed chassis. A towing triangular connecting frame is arranged on the towing hooks.
[0007] Preferably, uniformly distributed installation threaded grooves are formed in the bottom of the fixed chassis. An installation plate is arranged on the top of the universal wheel. Uniformly distributed installation holes coaxial with the installation threaded grooves are formed on the surface of the installation plate. Installation bolts penetrating through the installation holes are threadedly connected inside the installation threaded grooves.
[0008] Preferably, a first limit hole and a second limit hole are sequentially formed in the towing hook. A limit bolt is coaxially inserted into the first limit hole and the second limit hole. A limit nut is threadedly connected to the outside of the limit bolt below the towing hook.
[0009] Preferably, a towing rod is provided at one end of the towing triangular connecting frame away from the towing hook. One end of the towing rod away from the towing triangular connecting frame is fixedly connected with a towing plate. On one side of the towing plate away from the towing rod, towing ear plates are symmetrically and fixedly connected. Towing holes are formed in the towing ear plates.
[0010] Preferably, the towing triangular connecting frame is arranged on the towing hook.
[0011] Preferably, the cross-section of the towing triangular connecting frame is trapezoidal.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] When this equipment is in use, the box-type substation is lifted by a lifting device. Then, installation bolts are inserted into the installation holes and screwed into the installation thread grooves below the fixed chassis. A plurality of universal wheels are sequentially installed below the fixed chassis. Then, the lifting device is removed and the plurality of universal wheels are brought into contact with the ground. Then, the towing ear plates are connected with a towing device. In this way, the towing device can perform towing transportation on the box-type substation through the towing triangular connecting frame. During short-distance transportation, it is no longer necessary to lift by a crane and load and unload by a truck, which can effectively reduce the transportation cost. Description of the Drawings

[0020] Referring to Figures 1-4 , a towed substation includes a box-type substation 1. A fixed chassis 2 in the shape of a "return" is fixedly connected to the bottom of the box-type substation 1. Universal wheels 3 for transporting the box-type substation 1 are evenly distributed below the fixed chassis 2. On one side of the fixed chassis 2, L-shaped towing hooks 4 are symmetrically and fixedly connected. A towing triangular connection frame 5 is arranged on the towing hooks 4.
[0021] It should be noted that when using a forklift or other lifting equipment, only need to lift the box-type substation 1 by 20 cm - 30 cm, then install multiple universal wheels 3 at the bottom of the box-type substation 1. After installation, lower the box-type substation 1 and make multiple universal wheels 3 contact the ground surface;
[0022] Furthermore, mounting threaded grooves 6 are evenly distributed and opened at the bottom of the fixed chassis 2. Mounting plates 7 are arranged at the tops of the universal wheels 3. Mounting holes 8 that are evenly distributed and coaxially arranged with the mounting threaded grooves 6 are opened on the surfaces of the mounting plates 7. Mounting bolts 9 passing through the mounting holes 8 are threadedly connected inside the mounting threaded grooves 6;
[0023] It should be noted that by inserting the mounting bolts 9 into the mounting holes 8 and screwing them into the mounting threaded grooves 6 below the fixed chassis 2, the universal wheels 3 can be installed and fixed below the fixed chassis 2, which is convenient for transporting the box-type substation 1 through the universal wheels 3. When transported to the installation site, the universal wheels 3 can be disassembled.
[0024] Furthermore, a first limit hole 10 and a second limit hole 11 are sequentially opened on the towing hooks 4.

Through the limit bolt 12 with a fixed position, the towing triangular connection frame 5 can be restricted on the towing hooks 4, and the detachment of the towing triangular connection frame 5 can be prevented.
[0026] Further, a towing rod 14 is provided at one end of the towing triangular connecting frame 5 away from the towing hook 4. A towing plate 15 is fixedly connected to the end of the towing rod 14 away from the towing device. Towing ear plates 16 are symmetrically and fixedly connected to one side of the towing plate 15 away from the towing rod 14. Towing holes 17 are formed in the towing ear plates 16.
[0027] It should be noted that the towing ear plate 16 is inserted into the towing plate 15 at one end of the towing device. Fixing holes are formed in the towing plate 15. The towing holes 17 are aligned with the fixing holes. Then, fixing bolts are inserted into the towing holes 17 and the fixing holes, and fixing nuts are used to fix the fixing bolts, so that the towing ear plate 16 can be connected to the towing device.
[0028] Further, the towing triangular connecting frame 5 is arranged on the towing hook 4.
[0029] Further, the cross-section of the towing triangular connecting frame 5 is trapezoidal.
