[0009] As an optimization, the clamping and stretching driving device comprises a clamping and stretching motor fixedly connected to the climbing body, a clamping and stretching screw rod extending in the up-down direction of the climbing body is in transmission connection with the driving end of the clamping and stretching motor, the clamping and stretching motor can drive the clamping and stretching screw rod to rotate, the clamping and stretching screw rod penetrates through the moving slide and is in screw connection with the moving slide;

[0012] As an optimization, a correction block is provided below the climbing body. A V-shaped correction groove is formed at the bottom of the correction block along the front-to-back direction. The V-shaped correction groove is a through groove. Correction rods are positioned below the movable slide block, spaced apart along the front-to-back direction of the climbing body. The correction rods extend along the vertical direction of the climbing body. A correction mounting part is provided on the climbing body corresponding to the position of the correction rod.

The lower ends of the two correction rods are fixedly connected by correction connecting parts. At the top of the correction block, a limiting block is fixedly connected to the upper end of the correction rod. A support spring is sleeved on the rod body between the limiting block and the correction mounting part. The two ends of the support spring abut against the limiting block and the correction mounting part, respectively.

The tower angle steel is usually connected to another tower angle steel through a connecting plate, so that the V-shaped roller is prone to interfering with the connecting plate when rolling; therefore, when such a situation occurs, the rotating shaft is driven to rotate by the roller overturning motor, that is, the wheel arm is driven to rotate, the position of the V-shaped roller is adjusted, and the interference is avoided.
