[0022] Please refer to Figures 1-4 As shown, an auxiliary hanging tool for a transmission line tower includes a fixed cylinder 1; an inlet cavity 2 is provided inside the fixed cylinder 1; a hook 3 is fixed on the barrel body of the fixed cylinder 1; an auxiliary shock-absorbing device is installed on the fixed cylinder 1; the auxiliary shock-absorbing device includes a rotating groove 401; the rotating groove 401 is provided at the center-symmetric position inside the fixed cylinder 1; a card slot 402 is provided on the side surface of the fixed cylinder 1; the card slot 402 communicates with the rotating groove 401; the vertical inner wall surface of the card slot 402 coincides with the vertical inner wall surface of the rotating groove 401.

[0023] Inside the rotation groove 401, there is a clamping block 403; between the clamping blocks 403, a rotating ring 404 is fixedly connected; inside the rotating ring 404, a structure cavity 405 is enclosed; on the inner wall toroidal surface of the structure cavity 405, a telescopic cavity 406 is opened; on the inner wall surface of the telescopic cavity 406, a spring 407 is installed in a surrounding manner; the acting end of the spring 407 is fixedly connected with an annular shock-absorbing block 408; on the inner wall arc surface of the shock-absorbing block 408, rolling grooves 409 are opened in a surrounding manner; inside the rolling grooves 409, small ball bearings 410 are rotatably installed; the vertical cross-sectional dimension of the clamping block 403 is smaller than the vertical cross-sectional dimension of the clamping groove 402; the cross-sectional diameter of the rotating ring 404 is the same as the cross-sectional diameter of the wire inlet cavity 2; the thickness of the clamping block 403 is the same as the thickness of the rotating ring 404; the thickness of the rotating ring 404 is the same as the opening depth of the rotation groove 401; when the spring 407 is not acting, it does not deform; when the spring 407 is not acting, the center line of the acting range of the shock-absorbing block 408 coincides with the center line of the acting range of the fixed cylinder 1; on the vertical structural surface of the fixed cylinder 1, fixing holes 412 are symmetrically opened; the fixing holes 412 penetrate through the opening space of the rotation groove 401; on the vertical surface of the clamping block 403, a threaded hole 411 is penetrated and opened; when the clamping block 403 is in a horizontal state inside the rotation groove 401, the center lines of the fixing hole 412 and the threaded hole 411 coincide; inside the fixing hole 412 and the threaded hole 411, a screw 413 is installed;

[0024] During operation, when the existing auxiliary hanging device for transmission line towers is in operation, since the line operation environment is usually outdoors, under the interference of external wind or rain, the wire will vibrate, and the hanging device will also vibrate accordingly, causing friction between the line and the hanging device, which not only affects the normal operation of the line but also reduces the service life of the hanging device.

[0025] Working principle: During the installation of components on a transmission line tower, an auxiliary hanger is needed to install the line to ensure the smooth progress of the power project; when the existing auxiliary hanger for a transmission line iron tower is in operation, since the line operation environment is usually outdoors, under the interference of external wind or rain, the wire will vibrate, and the hanger will also vibrate accordingly, causing friction between the line and the hanger, which not only affects the normal operation of the line but also reduces the service life of the hanger. In this application, the auxiliary shock-absorbing device is used. The block 403 is pushed into the interior of the rotating slot 401 through the slot 402, and a rotational force is applied to the rotating ring 404 to make the block 403 in a horizontal state. Then, the screw 413 is installed in the threaded hole 411 and the fixing hole 412, so as to fix the rotating ring 404 inside the incoming line cavity 2. After the line is suspended and fixed by the fixing cylinder 1, once the line vibrates due to the blowing of the wind, the vibration force is transmitted to the shock-absorbing block 408 through the small balls 410 in the rolling slot 409, avoiding high-frequency friction between the line and the hanger. Under the cooperation of the spring 407 in the telescopic cavity 406, the spring 407 undergoes telescopic movement, and the vibration force is reduced, reducing the vibration of the hanger under the influence of the external environment, extending its service life, and ensuring the normal operation of the line.
