s3: when the hat support 1 passes through the clamping ring 13, the hat support collides with the inclined surface 18 at the bottom of the telescopic rod 16, so that the telescopic rod 16 is retracted into the ring rod 14, the hat support 1 penetrates through the clamping ring 13 and is positioned above the clamping ring 13, and the telescopic rod 16 extends out at the moment and is closed with the adjacent ring rod 14 to form a ring;

s4: when the motor 12 is stopped, the cap support 1 falls on the snap ring 13, and the umbrella-shaped cable membrane is positioned at the upper end of the steel column 9.

The motor 12 drives the cap support 1 to rise upwards along the steel column 9 until the upper end of the steel column 9 is erected.

In this embodiment, the motor 12 is coaxially connected with a driving wheel 43, the driving wheel 43 is connected with a driven wheel 19, the driven wheel 19 is connected with the pull rope 11, the driven wheel 19 is provided with four radial sliding chutes 21 and is located at a position 90 degrees apart, the driving wheel 43 is provided with a roller 20, each rotation of the roller 20 is meshed with one sliding chute 21, so that the driven wheel 19 rotates 1/4 times, an inner arc surface 22 is formed between every two adjacent sliding chutes 21, the driving wheel 43 is provided with a coaxial surface 23 which is meshed with the inner arc surface 22, and during rotation, an inner concave surface 24 is arranged on the coaxial surface 23 to form a gap in which the inner arc surface 22 can rotate;

the umbrella-shaped cable membrane rises intermittently along with the cap support 1, so that the inertia force is prevented from being too large and the braking is difficult when the umbrella-shaped cable membrane rises continuously.

In the present embodiment, the cap stay 1 includes:

the support 42 is connected to the steel column 9 in a sliding mode;

the supporting rod 40 is fixedly connected with the support 42, arranged around the steel column 9, and provided with a ring steel pipe 41 at one end far away from the support 42, and the upper part of the ring steel pipe 41 is provided with a first fixed pulley 5;

the support 42 is positioned between two adjacent support plates 15;

the support 42 collides with the inclined surface 18 at the bottom of the telescopic rod 16, namely, the clamping ring 13 can be penetrated through, which is very convenient.

The cable membrane installation method can be used for cable membrane installation on the ground, the installation site is large, the transportation of accessories is convenient, the construction safety can be guaranteed, and the construction efficiency is higher.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several equivalent substitutions or obvious modifications can be made without departing from the spirit of the invention, and all the properties or uses are considered to be within the scope of the invention.
