Self-balancing arc cable saddle

Abstract

The invention discloses a self-balancing arc cable saddle, which comprises a tower cable saddle longitudinal beam, wherein at least three cable saddle wheel devices are arranged on a vertical plane of the cable saddle longitudinal beam from low to high at intervals; a first cable saddle wheel device is vertical to a tower top main beam; a first acute included angle is formed in a horizontal plane between the last cable saddle wheel device and the first cable saddle wheel device; the first cable saddle wheel device is horizontally arranged in the vertical plane; the last cable saddle wheel device is arranged on the vertical plane in an inclined mode and has a first inclination angle; and the inclination direction of the last cable saddle wheel device inclines downwards along the direction of the acute included angle formed in the horizontal plane between the last cable saddle wheel device and the first cable saddle wheel device. A main cable of the self-balancing arc cable saddle realizes horizontal turning, and the component force generated by the inclination of the cable saddle counteracts the horizontal force generated by the horizontal turning of the main cable to realize self balancing, thereby making cable saddle wheels in a pure compression state and greatly reducing the abrasion of a rope system. The self-balancing arc cable saddle adopts at least three rows of the cable saddle wheels from front to back, has a simplified structure system, and reduces the manufacturing difficulty degree and the dead weight.

Description

technical field [0001] The invention belongs to the field of bridge construction equipment, in particular to an arc-shaped cable saddle for guiding cables. Background technique [0002] There are two main types of rope steering equipment currently used in cable hoisting systems: pulley systems and saddle systems. The pulley system is mainly used for the steering of rope systems such as traction ropes, hoisting ropes, and working ropes; the cable saddle system is mainly used for the steering of the main cable system of the crane. [0003] Most of the conventional cable-saddle systems have complex structures, large tonnage, and a large number of axles. The current cable saddle wheel devices are all set parallel to the horizontal plane, and also horizontally on the vertical surface. There is horizontal steering for the main cable. When the cable saddle with the above structure is in use, it cannot realize horizontal steering. Greater wear and tear will affect the service life...

[0003] Most of the conventional cable-saddle systems have complex structures, large tonnage, and a large number of axles

The current cable saddle wheel devices are all set parallel to the horizontal plane, and also horizontally on the vertical surface. There is horizontal steering for the main cable. When the cable saddle with the above structure is in use, it cannot realize horizontal steering. Greater wear and tear, affecting the service life of the cable

However, there is still no cable saddle to realize the horizontal steering of the cable and avoid the wear and tear of the main cable.
