Embodiment Construction
[0024] 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.
[0025] 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...

The invention relates to rope length control equipment, a rope length control method and a rope length control system of a super-lifting device as well as an engineering machine. The super-lifting device comprises a super-lifting mast, a super-lifting winch and a compensation mechanism; a steel wire rope introduced from the super-lifting winch is led back to the super-lifting mast through a cantilever crane pulley device on a cantilever crane system, and is connected with the compensation mechanism; the control equipment comprises a receiving device for receiving the length of the steel wire rope, and a control device for comparing the length of the steel wire rope with a pre-set rope length to obtain a comparing result, and controlling the compensation mechanism to actively retract according to a comparing result so as to enable the super-lifting winch to passively reel off, or controlling the super-lifting winch to actively reel, so that the compensation mechanism passively stretches out. The rope length control equipment, the rope length control method and the rope length control system provided by the invention can be used for controlling the length of the steel wire rope through the super-lifting winch and / or a compensation oil cylinder.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a device, method, system and construction machinery for controlling the length 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 main arm, and improving the s...
