As shown in fig. 1-2, the present embodiment provides a clamping chuck 5 for fixing a cable, which comprises four components, including two arc-shaped fixing grooves 1 and a semicircular groove formed in the middle. The semicircular groove and the outer diameter of the cable are matched to clamp the cable. The upper end and the lower end of one of the arc-shaped fixing grooves are welded with the eye plates 2, and the eye plates are used for connecting and fixing the steel wire rope. The two arc-shaped fixing grooves 1 form a complete clamping chuck 5 for fixing the cable through 3 bolts and 4 nuts.

Still provide a laying structure, cable 8 fix in the semicircular groove of the clamping chuck for fixed cable 5, and the clamping chuck for fixed cable 5 from top to bottom is connected the equipment with wire rope 6, guarantees that every certain distance has a clamping chuck for fixed cable 5 on cable 8, all cable clamping chuck middles all have wire rope 6 to connect. The support 7 is previously welded to the upper end inner wall of the cable tube 9. After the cable assembly is laid in the pipe, the upper end of the uppermost fixed cable is connected to the upper end of the chuck 5 by the wire rope 6 and the support 7. The clamping clamp for fixing the cable 5 can tightly attach to the inner wall of the cable pipe 7, reduce the shaking of the cable and play a role in protecting the cable by the factors of the hoisting force of the clamping clamp for fixing the cable 5, the support piece 7 and the steel wire rope 6 and the gravity tension of the cable itself.
