The most difficult point is that it is difficult to cut off the power supply of the busbar. When the busbar is not powered off, an appropriate safety distance needs to be reserved under the busbar. After removing the safety distance, there is only a limited and narrow space under the busbar.

The first fixed clamp 1 and the second fixed clamp 2 are fixed on the outer surface of the equipment support 8. The first fixed clamp 1 is located in the upper position, the left side of the first fixed clamp 1 is designed as a flat structure, the second fixed clamp 2 is located below the first fixed clamp 1, the lifting mechanism 3 is fixedly installed above the flat structure of the first fixed clamp 1, one end of the adjustable support rod 4 is connected to the left side position of the second fixed clamp 2, and the other end is connected to the lower position of the flat structure of the first fixed clamp 1. One end of the auxiliary support column 5 is connected to the lower part of the left flat structure of the first fixed clamp 1, and the other end is placed on the ground. The lifting mechanism 6 is installed at the upper end position of the lifting mechanism 3, and the induction radar 7 is installed above the upper end of the left side of the lifting mechanism 6.

[0046] In this embodiment, as Figure 1As shown, the device provides upward supporting force through the first fixed clamp 1, the second fixed clamp 2 and the auxiliary support column 5 to support the lifting of the lifting mechanism 3, so that the lifting mechanism 3 and the lifting mechanism 6 of the device can be safely and reliably attached to the original equipment bracket 8. The lifting mechanism 6 is used to lift electrical equipment. The induction radar 7 is located at the top position and can sense the distance between the device and the bus 10, so as to control the lifting height of the lifting mechanism 3, so that the distance of the device when lifting electrical equipment is within the safe distance below the bus. It realizes the hoisting of electrical equipment such as disconnecting switches and insulators below the bus within the safe distance in the narrow space scenario of the substation. The overall structure is simple, easy to install and disassemble, greatly improves work efficiency, ensures operation safety, and at the same time has a small footprint and is convenient for transportation.

[0047] The lifting mechanism 6 includes a lifting cross beam 61, a slider 62, a lifting pulley block 63, a steel wire rope 64, a hook 65 and an electric hoist 66. The lifting cross beam 61 is installed above the lifting mechanism 3. A chute is provided at the lower end of the lifting cross beam 61. The slider 62 is slidably connected in the chute. One end of the steel wire rope 64 is fixedly connected to the right side of the slider 62, and the other end passes through the hook 65 and is connected to the lifting pulley block 63 and finally connected to the electric hoist 66. The electric hoist 66 is installed on the ground. The hook 65 is connected to the steel wire rope 64 and is located below the slider 62.

The steel wire rope 64 passes through the first lifting pulley 631, the second lifting pulley 632 and the third lifting pulley 633 in sequence and is connected to the electric hoist 66.

[0049] In this embodiment, as Figure 5As shown in the figure, the slider 62 slidably connected below the lifting crossbeam 61 slides during the operation of the electric hoist 66 to realize the left - right movement of the hook 65 below the lifting crossbeam 61. At the same time, the electrical equipment connected to the hook 65 is moved to the installation position. The connection of the steel wire rope 64 on the lifting pulley block 63 realizes the up - down movement of the hook 65, moving the electrical equipment to an appropriate height. Thus, through the up - down movement of the hook 65 and the left - right movement of the slider 62, the up - down and left - right movement of the electrical equipment below the hook 65 can be achieved, and the electrical equipment can be placed above the equipment support 8 for installation. When the electric hoist 66 is in operation, it provides power to apply a tensile force on the steel wire rope 64 to the hook 65, changing the position of the hook 65 to realize up - down movement. When it moves to the highest position, the hook 65 cannot move in the up - down direction. At this time, the slider 62 moves left - right on the lifting crossbeam 61, and finally the installation of the electrical equipment is completed.

[0050] Embodiment Two

[0051] On the basis of the above - mentioned Embodiment One, since the heights of the equipment supports 8 of different electrical equipment are different, and the safety distances from the busbar 10 also vary. In order for this device to adapt to equipment supports 8 of different heights, Embodiment Two is proposed.

[0052] Specifically, the lifting mechanism 3 includes a lower lifting column 31, an upper lifting column 32, a lifting pulley block 33, a lifting motor, a wire rope 34, and a wire rope collecting wheel 35. The upper lifting column 32 and the lower lifting column 31 adopt a frame structure, and the upper lifting column 32 is located above the lower lifting column 31. The bottom surface of the lower lifting column 31 is installed above the flat structure of the first fixed clamp 1. A chute is provided inside the frame column of the lower lifting column 31. The frame size of the upper lifting column 32 is adapted to the frame of the lower lifting column 31. A protrusion is provided on the outer side of the frame of the upper lifting column 32, and the protrusion can move up and down in the chute of the lower lifting column 31. The lifting pulley block 33 is installed on the side surface of the lower lifting column 31. The wire rope collecting wheel 35 is installed on the side of the auxiliary support column 5. The output shaft of the lifting motor is connected to the rotating shaft of the wire rope collecting wheel 35. One end of the wire rope 34 is fixedly connected to the middle position of the column body at the bottom surface of the upper lifting column 32, and the other end passes through the lifting pulley block 33 and is connected to the wire rope collecting wheel 35.

[0053] Specifically, the lifting pulley set 33 includes a first lifting pulley 331, a second lifting pulley 332, and a third lifting pulley 333. The first lifting pulley 331 is installed at the middle position of the upper end of the lower lifting column 31.

The rope discharging 34 sequentially passes through the first lifting pulley 331, the second lifting pulley 332, and the third lifting pulley 333 and is connected to the rope collecting wheel 35.

[0054] In this embodiment, as Figure 3 , Figure 4 shown, the lifting mechanism 3 is designed with a sliding connection between the upper lifting column 31 and the lower lifting column 32. By the action of the rope collecting wheel 35, the rope discharging 34 wound thereon provides a pulling force to the upper lifting column 31, enabling the upper lifting column 31 to slide inside the lower lifting column 32 to achieve upward movement. In the working state of the induction radar 7, it can sense the safety distance from the busbar 10. When lifted to the actual required height, a fixed buckle is used between the upper lifting column 31 and the lower lifting column 32 to fix its position, and at the same time, the position of the rope collecting wheel 35 is fixed to ensure no rotation, thereby ensuring that the device is within a safe working range and enabling the installation of electrical equipment without power outage of the busbar 10. The rope collecting wheel 35 operates under the control of the lifting motor, which can reduce the physical strength of the staff and improve the operation efficiency.

[0055] Specifically, the cross-section of the frame structure is square, and the weights of the upper lifting column 32 and the lower lifting column 31 are less than 20 kg.

The column body 51 and the chassis 52 are integrally formed to ensure the stability of the entire auxiliary support column 5. At the same time, the diameter of the chassis 52 is 3 times that of the column body 51. The large area of the chassis 52 results in a small pressure per unit area, increasing the overall stability of the device and ensuring safety during use.

[0060] Specifically, the column body 51 of the auxiliary support column 5 adopts a telescopic design and is composed of two mutually cooperating column bodies. One of the column bodies is designed with protrusions, and the other column body is provided with equally spaced fixing holes.

[0061] Specifically, the adjustable support rod 4 adopts a telescopic structure design and is composed of two mutually cooperating support rods. One of the support rods is designed with protrusions, and the other support rod is provided with equally spaced fixing holes.
