Lifting steel wire rope breakage preventing device for tower crane

Abstract

The invention discloses a lifting steel wire rope breakage preventing device for a tower crane. The crane, end plates and stand columns are included, the upper end of the upper end plate is fixedly connected with the crane, a winding and unwinding assembly is arranged on the outer wall of one end plate, and the winding and unwinding assembly comprises a first support seat, an auxiliary steel wirerope, grooved pulleys, material rollers, a servo motor, bearings, a first vertical plate and a main steel wire rope. The outer side of the grooved pulley on the outer side is connected with the main steel wire rope in an attached mode, and the upper end of the main steel wire rope is connected with an internal winding-unwinding roller of the crane in a winding mode. The lifting steel wire rope breakage preventing device for the tower crane is scientific and reasonable in structure and safe and convenient to use, and is provided with the main steel wire rope, a pulley, the material rollers, a disc, a pawl, a ratchet wheel, a lifting ring, the servo motor and the auxiliary steel wire rope, the material rollers can pull the lifting ring and hoist an object through the auxiliary steel wire rope, and the problem that when the steel wire rope is broken, part of the steel wire rope needs to be clamped on one side to clamp the position of the hoisted object, gravity center shifting and shakingare likely to happen, and potential safety hazards exist is solved.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a hoisting wire rope breakage prevention device for tower cranes. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Steel pipes and other construction raw materials, although the existing technology can realize the clamping protection of the lifting object when the wire rope breaks, but in the existing technology, when the wire rope breaks, part of the wire rope needs to be clamped by one side to clamp the lifting object, and the position of the lifting object is prone to center of gravity. Misalignment and shaking lead to problems with potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a hoisting wire rope anti-breakage device for tower cranes, to solve the problem in the above background technology that when the wire rope br...
