Abstract
The invention discloses a steel wire rope clamping device based on air pressure transmission. The steel wire rope clamping device based on air pressure transmission comprises a steel wire rope clamping device, an air cylinder and a control cabinet. A cantilever double crawler and lower crawler ejecting and clamping structure is adopted in the steel wire rope clamping device and reasonable matching is achieved through an air pressure system, so that the clamping force of the crawlers on a steel wire rope is 25 times the tension value of the steel wire rope. Thus, self-adapting flexible control of the clamping force of an ejecting crawler and set tension is achieved. Under the condition that constant tension is exerted on the steel wire rope, the minimal deformation amount of the steel wire rope is automatically obtained and damage to the steel wire rope is avoided. In addition, constant damping force is exerted on the steel wire rope and rope disordering will not happen to the steel wire rope.
