Problems solved by technology

[0003] When the tower crane is hoisting materials, the motor drives the wire rope to shrink, and the wire rope is pre-tightened and locked. If the load on the motor is too large, it is easy to cause damage to the motor, reduce the service life of the tower crane, and increase economic expenditure. When the tower crane lifts heavy materials, the steel wire rope is easily driven down by the materials, which poses a great safety hazard, and accidents are prone to cause construction personnel casualties

Abstract

The invention relates to the technical field of steel wire rope pre-tightening and locking devices, in particular to a steel wire rope pre-tightening and locking device of a tower crane. The steel wire rope can be conveniently pre-tightened and locked, and is extruded through a fixing column to increase friction between the steel wire rope and a machine body, so that the steel wire rope cannot move rapidly, is clamped through the two clamping plates, cannot move, and is pre-tightened and locked through a pure mechanical structure, and thus, the burden of a motor is relieved, damage probability of the motor is reduced, the service life of the motor is prolonged, the service life of the tower crane is prolonged, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of a steel wire rope pretension locking device, in particular to a steel wire rope pretension locking device for a tower crane. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Tower crane is an indispensable equipment on the construction site. [0003] When the tower crane is hoisting materials, the motor drives the wire rope to shrink, and the wire rope is pre-tightened and locked. If the load on the motor is too large, it is easy to cause damage to the motor, reduce the service life of the tower crane, and increase economic expenditure. When the tower crane lifts heavy materials, the steel wire rope is easily driven down by the materials, which has great potential safety hazards, and accidents are prone to cause casualties of construction personnel. [0004] For this reason, the present invention proposes a tower cr...
