Problems solved by technology

In addition, even if the weight of the steel wire rope in front of the main boom 4' is greater than the weight of the steel wire rope behind the main boom 4' in advance, the luffing jib 3' will still carry the load during the luffing and extension process of the main boom 4'. Pulling the heavy wire rope 1' backward, there is still a danger that the weight of the wire rope in front of the main boom 4' is greater than the weight of the lifting wire rope 1' behind the main boom 4'

Abstract

The invention relates to a hoisting and winching control device capable of preventing a rope from messing and a control method. The hoisting and winching control device comprises a stringing winch and an auxiliary steel wire rope, wherein one end of the auxiliary steel wire rope is fixedly connected to the stringing winch, and the other end thereof winds the stringing winch and then is connected with a hoisting steel wire rope winding an arm head of a crane, so as to enable the hoisting steel wire rope to be in a tensioning state. The hoisting and winching control device disclosed by the invention enables the hoisting steel wire rope to be in the tensioning state during the arm rising and descending processes, so as to prevent the situation that the weight of the hoisting steel wire rope in front of a main arm is lighter than that of the hoisting steel wire rope in the back of the main arm, and avoid the rope messing phenomenon of the hoisting steel wire rope.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a hoisting winch anti-disorder rope control device and control method. Background technique [0002] With the continuous improvement of the research and development level of crane technology and the increasing demand for large-tonnage and super-large-tonnage cranes in the market, cranes are developing in the direction of stronger lifting capacity, longer arm length and diversified combinations. Large-tonnage and super-large-tonnage cranes are all The application of ground cranes is becoming more and more extensive, and the frequency of use is also increasing. In order to meet the hoisting load at higher heights and larger amplitudes, the super-large-tonnage cranes have added a luffing jib working condition, and the luffing jib is usually installed on the box-type telescopic main jib (referred to as "main jib") head. [0003] figure 1 It is a schematic diagram of the state...
