Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] The construction machinery provided by the present invention is described by taking a telescopic boom crane with a super-lifting device as an example, but it is not limited thereto. figure 1 It is a schematic diagram of the structure of the crane including the compensation mechanism. The structure of the crane is as figure 1 As shown, it mainly includes a pulley block 1, a steel wire rope 2, a compensation mechanism 3 (the compensation mechanism can be an elastic element that can be contracted under load such as an oil cylinder, a spring), a superlift mast 4, a rear tensioning device 5, and a basic arm 6 , turntable 7, luffing oil cylinder 8, super hois...

Abstract

The invention relates to control equipment, a method, a system and an engineering machine for the retractable rope compensation of a guying device. The guying device comprises a guying mast, a guying winch and a compensation mechanism, and a steel wire rope which is led out from the guying winch is led back to the guying mast after passing by a boom pulley device on a boom device, and is connected with the compensation mechanism; the control equipment comprises a receiving device and a control device, wherein the receiving device is used for receiving the pressure of the compensation mechanism; and the control device is used for comparing the pressure of the compensation mechanism with a first set pressure scope, a first comparison result is obtained, the compensation mechanism is controlled to extend or retract according to the first comparison result, so the steel wire rope is in a tensioning state. The equipment can be used for effectively solving the problem of the too long or too short retractable rope when the speed of the guying winch retractable rope cannot follow the extension speed of a boom, and the tensioning degree of the steel wire rope is actively adjusted, so the appropriate tensioning force of the steel wire rope is kept.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a compensation control device, method, system and construction machinery for retracting and unwinding ropes of a super-lifting device. Background technique [0002] With the development of wind power, nuclear power, chemical industry and other industries, the components are increasingly modularized and large-scale, and the demand for large-tonnage cranes is increasing, which requires the lifting height and lifting load of the crane to increase. Development in the direction of large-scale. However, the high lifting height and heavy lifting load will lead to a large component force in the shear direction of the main boom, which makes the deflection of the main boom in the luffing plane larger, and the stability of the main boom in the slewing plane is poor. Increasing the length of the main arm, optimizing the shape of the main arm, increasing the cross-sectional size of the ...
