Vertical shaft traction cable clamp with guiding and avoiding functions

Abstract

The invention provides a vertical shaft traction cable clamp with guiding and avoiding functions. The vertical shaft traction cable clamp comprises at least one group of clamp single-pieces, wherein each clamp single-piece comprises a hollow housing and a clamp body; the clamp body comprises a cable clamp and a steel wire rope clamp; a housing comprises a circular table body and a cylindrical barrel; each cable clamp comprises a U-shaped bolt, an arc-shaped board and angle steel; and each steel wire rope clamp comprises a single line clamp which is in one-to-one correspondence to the U-shaped bolt. According to the technical scheme applied by the invention, the vertical shaft traction cable clamp has the beneficial effects that: firstly, the integral structure is simplified, and space usage is small; secondly, the housing achieves the dual effects of protecting and guiding, i.e., the housing achieves the protecting effect for the clamp bodies arranged inside the vertical shaft traction cable clamp; and by virtue of the design of the circular table body, the housing can effectively avoid horizontal barriers along the conical surface of the housing, so that quick hoisting of cables is realized; and thirdly, by virtue of the structures of the cable clamps as well as a combined design of the cable clamps and the steel wire rope clamps, damages to the cables in a hoisting process can be reduced to the greatest extent, and the safety and hoisting speed in the hoisting process can be improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a shaft traction cable clamp with guidance and avoidance. Background technique [0002] For the laying and installation of high-rise shaft cables, due to the heavy weight of the super-high-rise building cables, if the cable body is hoisted during the cable laying process, the tension generated by the cable's own weight will cause the cables to become thinner or even break. A steel wire rope is attached to the cable, and multiple clamps are used to fix the steel wire rope and the cable at a certain distance, and the hoist is used to pull the steel wire rope, so that the weight of the cable is evenly distributed on the steel wire rope, and the cable is not damaged while lifting the traction cable. [0003] Traditional cable clamps use hoops, splints or wire ropes. The details are as follows: a patent application with an application date of 201410567552.0 discloses a cable cla...

Problems solved by technology

[0004] The existing clamps have the following defects: (1) The existing clamps are too tight to easily damage the cable skin; the weight of the cable cannot be completely distributed on the wire rope if the lock is too loose, resulting in the cable being easily separated from the clamp during hoisting; (2) ) Most of the existing clamps protrude outside the cables and steel wire ropes. During the cable lifting process, the cables will shake to a certain extent, and the cable clamps will easily collide with the horizontal floor or the horizontal limit device, causing the cable clamps to fall off or the cable sheath to be damaged. In order to ensure the safety of construction, it is generally necessary to set up a special person to take care of every few floors. The caretaker directs the hoist to be pulled and hoisted through the signal. The construction efficiency is low and the construction cost is high.
