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.

    本发明涉及钢丝绳预紧锁定装置技术领域,具体为一种塔式起重机钢丝绳预紧锁定装置。本发明可以方便对钢丝绳进行预紧锁定,通过固定柱挤压钢丝绳增大钢丝绳与机体的摩擦,使得钢丝绳无法快速移动,在通过两块夹板将钢丝绳夹紧,使得钢丝绳无法移动,通过纯机械的结构来实现预紧锁定钢丝绳,减轻电动机的负担,减少电动机的损坏几率,使得电动机的使用寿命得以延长,增加塔式起重机的使用年限,增加经济效益。
