Description

Auxiliary assembling tool for multiplying power conversion of crane

Technical Field

The utility model relates to the technical field of crane multiplying power conversion, in particular to an auxiliary assembling tool for crane multiplying power conversion.

Background

When the crane is used for hoisting under different working conditions, the multiplying power of the steel wire rope of the crane needs to be adjusted at any time, and the multiplying power of the steel wire rope depends on the multiplying power of the pulley. The more the number of times that the wire rope passes through the pulley is around, the greater the multiplying power, and conversely, the less the multiplying power. The pulley block with large multiplying power is suitable for loading and unloading equipment with large weight, can reduce the resistance of the roller and the tension of the steel wire rope, and ensures the operation safety; the pulley block with small multiplying power is suitable for lighter objects, the number of times that ropes penetrate the pulley block can be reduced, the lifting speed is high, the operation time is shortened, and the working efficiency is improved. Therefore, the worker can perform the magnification conversion at any time according to the work requirement.

The traditional assembly process of multiplying power conversion of the wedge-shaped rope end lock crane is as follows: when the steel wire rope and the wedge lock are assembled, firstly, the steel wire rope is penetrated to the other side from the locking port of the wedge lock, the iron wedge is inserted into the middle of the wedge lock, then the steel wire rope is wound back to the locking port, the iron wedge is tightly wrapped by the iron wedge, and the iron wedge is firmly clamped in the locking block by the tension of the steel wire rope, so that the wedge lock is tightly attached to the steel wire rope, and the combined connection of the steel wire rope and the wedge lock is achieved. The traditional assembly method is completed by manpower and bare hands, and because the steel wire rope is thicker, has strong toughness and larger elasticity, the operation is very troublesome, at least two people need to grasp the tail end of the steel wire rope and the pin hole of the wedge-shaped lock respectively for forcefully homing the steel wire rope, and the residual length of the rope end part at the lower end of the lock head after assembly cannot exceed 20 cm. Therefore, the situation that the steel wire rope is sprung and hurts people due to the fact that the steel wire rope is too short, the manual force is insufficient, the space in the locking block is narrow and the like often occurs in the pulling process, and the situation that the steel wire rope is left too long and unqualified after assembly and needs to be repeatedly operated to further increase the operation intensity can also occur. Therefore, the conventional assembly method is time-consuming and labor-consuming, and has a certain degree of danger.
