[0002] Transformer maintenance requires the use of multiple φ65 oil hoses to handle the oil of the transformer, and the oil hoses and the oil hoses and the transformer-related flanges are generally connected with quick-release connectors. Since the pipeline needs to cross the top of the transformer tank, in order to prevent the oil hose from sagging and causing the quick-release connector to leak or loosen, the very heavy full oil pipeline is often suspended in the air so that the oil pipeline at the top of the transformer tank is roughly level with the quick-release connector. In the past, ropes were generally used to fix the oil hoses. When fixing, the upper ends of the multiple ropes were tied to the bracket on the top of the transformer, and the lower ends were tied to the oil hoses. The use of ropes is not only inconvenient to install and disassemble, but also inconvenient to adjust the height of the oil hose. Utility Model Content

[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0029] Please refer to Figures 1-7 , a fixing device for an oil transmission hose of a transformer, including a winch 20 for winding and unwinding a steel wire rope 10, a pulley 30, and a hoop 40. One end of the steel wire rope 10 is wound around the winch 20, and the other end passes through the pulley 30 and is connected to the hoop 40. The winch 20 is used to be installed on the side wall of the transformer 50, and the hoop 40 is used to be installed on the oil transmission hose 60. When in use, the oil transmission hose 60 is fixed by the hoop 40, the direction of the steel wire rope 10 is changed by the pulley 30, and the steel wire rope 10 is wound and unwound by the winch 20, so that the oil transmission hose 60 can be conveniently towed and fixed, and the height of the oil transmission hose can be conveniently adjusted by the winch 20.

[0030] In a preferred solution, a switch-type magnetic base 21 is installed at the bottom of the winch 20. The switch-type magnetic base 21 is a prior art, which is convenient to install the winch 20 on the side wall of the transformer 50 by magnetic attraction. Please refer to Figure 1 . The winch 20 is bolted to the switch-type magnetic base 21.

[0031] In a preferred solution, the pulley 30 is a hook-type pulley. The hook-type pulley is a prior art and can be purchased as a finished product on the market. By adopting the hook-type pulley, it is convenient to hook and install on the metal framework above the transformer 50.

[0032] The hoop 40 can be a structure in which two common half-rings are connected by bolts, but it is inconvenient to install the bolts. Therefore, please refer to Figures 4-7The hoop 40 includes a first half ring 41 and a second half ring 42, one end of the first half ring 41 and the second half ring 42 are hinged by a pivot, the outer wall of the first half ring 41 is provided with a plurality of first flanges 411, an arc-shaped slide groove 412 is provided in the first flange 411, and an arc-shaped locking rod 413 is installed in the arc-shaped slide groove 412, the outer wall of the second half ring 42 is provided with a plurality of second flanges 421, and the other end of the second half ring 42 is provided with a limiting hole 422 for inserting the arc-shaped locking rod 413 in the second flange 421; one end of the arc-shaped locking rod 413 radially extends out of the arc-shaped slide groove 412, and the other end can be inserted into the limiting hole 422; the other end of the first half ring 41 is provided with a connecting plate 415, and the connecting plate 415 is provided with a connecting hole 416, and the steel wire rope 10 is connected to the connecting plate 415 through the connecting hole 416. When the oil delivery hose 60 needs to be fixed, the first half ring 41 and the second half ring 42 are closed, and the arc-shaped locking rod 413 is pushed. Figure 6 , so that the arc-shaped locking rod 413 enters the limiting hole 422. Figure 7 Due to the limitation of the arc-shaped locking rod 413, the second half ring 42 will not open.

[0033] It should be noted that the diameter of the bottom of the arc-shaped slide groove 412 is larger than the width of the upper opening, and the arc-shaped locking rod 413 is a cylindrical structure, so that the arc-shaped locking rod 413 slides in a limited position at the bottom of the arc-shaped slide groove 412, and the end of the arc-shaped locking rod 413 radially extending out of the arc-shaped slide groove 412 has a smaller diameter, so that the arc-shaped locking rod 413 is stuck in the arc-shaped slide groove 412 and slides.

[0034] Further, see Figure 4 The ends of the three arc-shaped locking rods 413 radially extending out of the arc-shaped sliding groove 412 are all connected to the connecting rod 414. By moving the connecting rod 414, the three arc-shaped locking rods 413 can be moved at the same time.

[0035] Furthermore, the inner walls of the first half ring 41 and the second half ring 42 are provided with a protective pad 43. The protective pad 43 can be made of flexible rubber to increase the friction between the clamp 40 and the oil delivery hose 60 and prevent the clamp 40 from sliding.

[0036] Furthermore, two ends of the protective pad 43 extend out of the first half ring 41 and the second half ring 42 , so as to prevent the ends of the first half ring 41 and the second half ring 42 from causing damage to the oil delivery hose 60 .

[0037] The working principle or action process of the utility model is as follows:

[0038] When using, see Figure 1, The winch 20 is magnetically adsorbed on the side wall of the transformer 50 through the switch-type magnetic base 21. The pulley 30 is hook-mounted on the metal skeleton above the transformer 50. The hoop 40 holds the oil delivery hose 60 through the first half-ring 41 and the second half-ring 42, so that the oil delivery hose 60 can be conveniently towed and fixed, and the height of the oil delivery hose can be conveniently adjusted through the winch 20.
