[0042] An electromagnetic suction cup mechanism is arranged on the bottom plate 1 and is used to suck the surface of the power transformer to fix the device to the power transformer;

[0043] The electromagnetic chuck mechanism includes:

[0044] A curved rod column 2 is fixedly connected to the surface of the bottom plate 1 with a raised block, a notch is provided on the end face of the curved rod column 2, the groove wall of the notch is hinged to the side face of the raised block on the bottom plate 1, and a similar notch is also provided on the other end face of the curved rod column 2, the groove wall of the notch is rotatably connected to a fixed rod 3, and one end of the fixed rod 3 close to the sliding frame 10 is hinged to the surface of the sliding frame 10;

[0045] The sliding rod 12 and the fixed rod 3 are provided with a through slot on their end faces, the slot wall of the slot is slidably connected to the surface of the sliding rod 12, and the surface of the sliding rod 12 is provided with a clamping slot, and the surface of the fixed rod 3 is provided with a clamping piece, the clamping slot on the surface of the sliding rod 12 can be clamped and fixed with the clamping piece on the surface of the fixed rod 3, and the end of the sliding rod 12 away from the fixed rod 3 is rotatably connected to an electromagnetic suction cup 13, and the electromagnetic suction cup 13 is used to suck the surface of the power transformer;

[0046] The present mechanism is provided with three, and all of them are hinged to the surface of the bottom plate 1.

[0047] More specifically, in this embodiment: when using the device, first, by pushing the sliding frame 10, the sliding frame 10 and the fixed rod 3 are further offset in angle, and in the process of rotating the fixed rod 3, the bent rod column 1 2 is further driven to deflect in a certain direction, so that the fixed rod 3 and the bent rod column 1 2 can be opened like an umbrella, and the sliding rod 2 12 is further opened, so that a triangle is formed between the three electromagnetic suction cups 13, and then the distance between the sliding rod 2 12 and the fixed rod 3 is adjusted, and the preparation before using the device is completed. After that, the electromagnetic suction cup 13 is brought into contact with the surface of the power transformer, and the electromagnetic suction cup 13 is energized so that the electromagnetic suction cup 13 has magnetic force, so that the device can be firmly fixed on the surface of the power transformer, so as to be used as a support point for the safety rope;

[0048] The setting of this mechanism can fix this device on the surface of the power transformer by adsorbing this device on the surface of the power transformer through the electromagnetic suction cup 13, which can further make the installation of this device more labor-saving and convenient when using this device. When disassembling this device, the electromagnetic suction cup 13 can be powered off, which further improves the practicality of this device. In addition, the distance between the electromagnetic suction cup 13 and the sliding rod 12 in this mechanism can be changed, and the distance between the sliding rod 12 and the fixed rod 3 can also be adjusted, so that this device can be adsorbed on the surfaces of more different types of power transformers, further improving the applicability of this device. This mechanism is also provided with three, and a triangle can be formed between the three electromagnetic suction cups 13. With the triangle as the base point, a stable and effective high-hanging and low-use hanging point device is formed, and each mechanism is also supported by a curved rod column 2, which further improves the stability of this device when in use.

[0049] It is worth noting that the present embodiment also includes: a rotation self-locking mechanism, which is arranged on the sliding frame 10 and is used to lock the present device after being fixedly connected to the power transformer;

[0050] The rotary self-locking mechanism comprises:

[0051] The outer surface of the spur gear row 11 and the fixed sleeve 9 is provided with a notch, the groove wall of the notch is fixedly connected to the non-tooth surface of the spur gear row 11, the outer surface of the sliding frame 10 is fixedly connected to a connecting plate 21, the side of the connecting plate 21 is provided with a through notch, the groove wall of the notch is rotatably connected to a rotating column 23, the surface of the rotating column 23 is rotatably connected to a gear 24, and the tooth surface of the gear 24 is meshed with the tooth surface of the spur gear row 11;

[0052] Rotating column 25, rotating column 1 23 has a through slot on its surface, the slot wall is rotatably connected to the surface of rotating column 25, the surface of rotating column 25 is also rotatably connected to a moving ring 28, the inner wall of the moving ring 28 is fixedly connected to a spring 1 22, the surface of rotating column 1 23 is also provided with a groove, the groove wall is fixedly connected to an end of the spring 1 22 away from the moving ring 28, and a ratchet 26 is fixedly connected to a side of the moving ring 28 away from the gear 24;

[0053] Connecting plate 2 14, the side surface of connecting plate 2 14 is fixedly connected to the outer surface of sliding frame 10, and a slot is also provided on the surface of connecting plate 2 14, the slot wall of which is rotatably connected to rotating column 3 31, and the end surface of rotating column 31 facing gear 24 is fixedly connected to ratchet 27, and the surface of ratchet 27 is meshed with the surface of pawl 26.

[0054] More specifically, in this embodiment, when the sliding frame 10 is moved downward, the connecting plate 1 21 and the connecting plate 2 14 are further driven to move downward, thereby further driving the gear 24 to roll on the surface of the spur gear row 11, causing the gear 24 to rotate. During the rotation of the gear 24, the rotating column 25 is further driven to rotate, which causes the moving ring 28 to rotate, thereby driving the pawl 26 to roll on the surface of the ratchet 27, so that the device has the following two motion states:

[0055] First, when the sliding frame 10 moves downward, it will further drive the gear 24 to rotate clockwise. When the gear 24 rotates clockwise, it will drive the moving ring 28 to rotate clockwise, and make the pawl 26 move on the surface of the ratchet wheel 27, which will not affect the normal operation of the device;

[0056] Second, when the sliding frame 10 needs to move upward, the gear 24 will move in the opposite direction. During the reverse movement of the gear 24, the moving ring 28 will be driven to rotate counterclockwise, so that the ratchet 27 will get stuck on the pawl 26, making the gear 24 unable to rotate, thereby preventing the sliding frame 10 from moving upward.

[0057] The setting of this mechanism, through the coordinated use of the pawl 26 and the ratchet 27, further allows the sliding frame 10 to move only in one direction, so that when the sliding frame 10 is moved upward, it will not affect the normal opening of the device. When the sliding frame 10 is moved downward, the sliding frame 10 will be stuck and cannot be moved, so that the device can be better fixed when opened for use, reducing the possibility of movement of the device during operation, further improving the stability of the device, and the present mechanism is also provided with three, which can further improve the fixing effect of the position of the sliding frame 10 of the device.

[0062] A protruding piece 16, the end face of which is fixedly connected to the end face of the rotating column three 31, a protruding piece 2 15 is fixedly connected to the side of the connecting plate 2 14 facing away from the ratchet 27, the inner wall of the protruding piece 2 15 is slidably connected to the surface of the protruding piece 16, the surface of the protruding piece 16 is slidably connected to a sleeve 17, and the inner wall of the sleeve 17 is also slidably connected to the surface of the protruding piece 2 15.

[0063] More specifically, in this embodiment: when the device needs to be stored and the slide frame 10 does not need to be prevented from moving in the reverse direction, the sleeve 17 can be taken off the protruding member 16 and the protruding member 2 15, so as not to interfere with the rotation of the rotating column 31, and further, the pawl 26 can drive the ratchet wheel 27 to rotate in the reverse direction, so that the slide frame 10 can move away from the bottom plate 1, so that the device can be restored to be stored;

[0064] The arrangement of the present mechanism can fix the protruding piece 16 and the protruding piece 2 15 through the kit 17, so that the rotating column 31 cannot rotate, and further the ratchet 27 cannot rotate, so that the ratchet 27 can jam the pawl 26, so that the gear 24 cannot rotate in the opposite direction, and the purpose of unidirectional movement of the sliding frame 10 is achieved. When the kit 17 is removed, the ratchet 27 can be rotated, so that the limiting effect between the ratchet 27 and the pawl 26 is lost, so that the sliding frame 10 can rotate in the opposite direction. The fixing method is simple, and the storage of the present device is further facilitated without affecting the use, making the present device easier to store.

[0070] More specifically, in this embodiment: when the safety rope installation rod 7 needs to be opened and the safety rope is installed on the installation opening 6 on the safety rope installation rod 7, the clamping member 19 can be pressed, and then the safety rope installation rod 7 can be rotated so that the clamping member 19 is clamped with the clamping groove 20 on the right side of the rotating rod 18, so that the safety rope installation rod 7 can be opened. When the safety rope installation rod 7 needs to be closed, the same operation is performed, but the clamping member 19 is clamped with the clamping groove 20 below the rotating rod 18, so that the safety rope installation rod 7 can be further made to be close to the sliding rod 8;

[0071] The setting of this mechanism can further enable the device to have two postures by engaging the rotatable safety rope installation rod 7 with the engaging grooves 20 at different positions. First, when the safety rope installation rod 7 is opened, different installation openings 6 arranged on the surface of the safety rope installation rod 7 can be used to adapt to the operation activities at different positions of the transformer.
