Cable lifting tool

Abstract

The invention relates to a hoisting tool for cables, and belongs to the field of cable hoisting. The tool comprises a hanging plate, wherein a rectangular round head hook hole is formed in the upper part of the middle of the hanging plate; the two ends of the hanging plate adopt cavity structures and are provided with pin holes; the pin holes are fixedly linked with pins through pull rings; the pin holes are in nested connection with a lifting rope with rings at the two ends; an elastic device is arranged at the bottom of the hanging plate; a first pulley is connected with the bottom of the elastic device through a connecting shaft; the first pulley is connected with a second pulley through a wire rope; a circular hook is connected with the bottom of the second pulley; a hollow structure is arranged in the middle of the bottom of the circular hook. The tool can effectively avoid the swinging of a cable during hoisting through the connection between the elastic device and the two pulleys, can fix the cable through a locking bolt, can assist the hoisting of the cable through the circular lifting rope with the rings at the two ends, and is simple in structure, reasonable in design and high in practicability.

Description

technical field [0001] The invention relates to a cable hoisting tool, which belongs to the field of cable hoisting. Background technique [0002] A variety of pipelines cross in parallel in modern buildings, and the space is limited, especially in large-scale office buildings, financial commercial buildings, hotels, venues and other buildings, where information points are dense. In addition to floor grooves and wall-buried pipes, cables are laid in vertical shafts and pipes. Cable trays are widely used in the ceiling of the house to provide wiring in different directions. Various cables of the weak current system are arranged in the bridge tray. The bridge tray is a bracket for supporting and releasing cables. In the existing cable hoisting bridge, the support or hanger is directly welded to a fixed position on the steel structure, and a universal sling can also be used for installation. The universal spreader is generally used in steel structures, such as I-beam, angle st...

AI Technical Summary

Problems solved by technology

The universal spreader is generally used in steel structures, such as I-beam, angle steel, light steel keel and other structures. The spreader, fixture, boom, and hanger can be assembled into a whole in advance, and the fixed point can be fixed at the marked position. For hoisting, the hoisting clamps are crimped on the steel structure one by one, and the top wires are tightened. Such a hoisting structure is complicated, difficult to install, and inconvenient for cable inspection and maintenance, which cannot meet the needs of new markets.
