Embodiment 1

[0021] Embodiment 1: see figure 1 , the vertical laying cable spreader of the present invention includes a "worker" shape reel 8, a plurality of hooks 7 are evenly distributed on the upper face, and the lower face has a chassis 5 and a decomposed and combined disc 1 that is spliced ​​and fixed with steel wires. Composition, in which the superimposed surface of the upper and lower layers is a slope inclined towards the center. The upper plate surface, the chassis surface and the central column are integrated, and the central column is a hollow body. There are U-shaped positioning gaps 11 ( Figure 5 ), the decomposed and combined disk 1 of the fixed steel wire is thicker, and the number of combined pieces is the same as the number of steel wire ropes ( image 3 ), the splicing surfaces of adjacent pieces are complemented in a "Z" shape, and are combined into a whole by bolts 4, and each piece has an inverted tapered fixed wire rope through hole 2 ( Figure 4 ), the cable han...

Embodiment 2

[0022] Embodiment 2: Referring to Fig. 2, as mentioned above, the lower plate and the fixed wire rope drum 5 are of the same single-deck structure, and an inverted tapered hole 2 for fixing the wire rope is opened on it, and the cable supporting wire 6 is fixed in the inverted tapered hole.

[0023] When the cable is hoisted, the sling and the upper cable fixed on it are lifted to the fixed point of the cable shaft 3 through the hook 7, and then the splint 9 ( Image 6 , 7 ), the hanger is placed on the steel beam 13 on the cable well, and then the shelf and the steel beam are fixed with set screws 10.

Embodiment 3

[0024] Embodiment 3: As mentioned above, the hanger can also be an axially split body, which is especially suitable for cable suspension in the middle, and can save the trouble of cables passing through the center column.

Abstract

This invention relates to an improvement to the cable hook block for installing hanged cables characterizing that the cable-fixed hook block is in 'I', the lower disk of which is for fixedly connecting with the cable, the upper disk is for fixing the hanger. This invented hook block combines installing and fixing as one and saves large amount of fixing clamps, especially, the hollow structure of its central post can be used in hanging cables installing the cables in different directions without increasing cable connectors. The fixed lower disk double-lamination structure connects and fixes the cable hanged wires and connecting plates of the hook block before leaving the factory, it's not necessary to install them at site.

Description

technical field [0001] The present invention relates to the improvement of cable hanging and laying sling, especially relates to a hanging and laying cable sling which does not damage the cable, is easy to lay and fix, does not need to be separated, and can be suspended from the middle of the cable. Background technique [0002] High-rise buildings may need to hang and lay cables vertically, and one end of the main cable is suspended by a spreader to form a hanging lay. Existing hanging and laying cable spreaders such as Chinese patents CN02108623.0, CN02230490.8, CN02118736.3, CN200320120196.5, etc., all are to plug the cable end into the end hole of the spreader and press it tightly, or the cable end Clamp it with a chuck, and then connect it to the sling. The weight of this kind of suspension is all on the cable end. However, due to the low tensile strength of the copper conductor of the cable and the limited tensile force, it can only be used for low-height suspension o...
