Embodiment Construction
[0038] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0039] Such as figure 2 As shown, the hoisting device of the truck crane mainly includes a car body 1 , a telescopic boom 2 , a boom pitch mechanism 3 , a boom swing mechanism 4 , a retractable rope 5 and a load 6 .
[0040] The implementation process of the vehicle lifting anti-swing control technology in a complete lifting process is as follows: figure 1 As shown, when the lifting task starts, the "hook correction" technology is first used to lift the load; according to the actual situation of the load after lifting, when the load swings little, it will directly start lifting the load to the destination. "Moving swing elimination" technology, when the load still swings due to disturbances such as wind blowing or base instability after hoisting, the "fixed point swing elimination" technology is adopted to eliminate the swing of the load a...

The invention discloses automobile crane anti-swing control technology; firstly a load is hoisted by hook correction technology; based on the actual conditions of the hoisted load, when the load does not swing greatly, the load is hoisted to a destination directly; during the hoisting process, mobile swing eliminating technology is adopted; after the load is hoisted, if certain swing exists as a result of wind blowing or an instable pedestal, fixed-point swing eliminating technology is adopted; the swing of the load is eliminated above the hoisting point, and then the load is hoisted to a destination; during the hoisting process, mobile swing eliminating technology is adopted; based on the actual conditions when the load is above the destination, when the load does not swing greatly, the load is laid down directly; during the laying down process, dropping trench correction technology is adopted; if certain swing exists as a result of disturbance or poor mobile swing eliminating effect during the moving process of the load, fixed-point swing eliminating technology is adopted; the swing of the load is eliminated above the destination, and then the load is laid down; during the laying down process, dropping trench correction technology is adopted, and the load is ensured to be hoisted to the destination with precision and no swing. The technology provided by the invention can effectively prevent the swing of a hoisted load of an automobile crane, and thus ensures the smooth proceeding of engineering work and personnel safety; meanwhile the adoption of the technology greatly reduces requirements for automobile crane operators.
Description
technical field [0001] The invention belongs to the field of machinery and automatic control, and in particular relates to an anti-swing control technology of a truck crane. Background technique [0002] Cranes, also known as cranes, are widely used in modern factories as a handling tool. They play an important role in production and are essential for factories, warehouses, etc. Less loading and unloading tools. [0003] Cranes can be divided into two types according to their structure, overhead bridge cranes and slewing cranes. The first type of crane includes a trolley that can move in the horizontal direction, and the rope is installed under the trolley to lift goods; Type crane, this type of crane has a base that can rotate in space, which includes two structures, one is a tower crane, and the other is a tappet crane, which is mainly installed on movable machinery, such as car or boat etc. [0004] A truck crane is a truck that installs the crane on a general-purpose ...
