[0002] Vertical hoisting (the hoisting wire rope is vertical) is the basic requirement for safe operation of the crane, but the crane itself does not have vertical hoisting display and monitoring equipment
In many special working conditions, vertical lifting cannot be achieved, and only inclined lifting can be adopted based on the subjective judgment of the operator.
In addition, double-machine hoisting and single-machine hoisting are both basic operations of cranes. Double-machine lifting has risks. The analysis of the risks of double-machine lifting found that it mainly comes from abnormal load changes and non-vertical hoisting of the cranes. It is related to knowing the dynamic information of the other party's lifting and not being able to grasp the lifting angle of oneself in real time

The invention relates to a crane hoisting angle detecting device and a crane. The crane comprises a fixed pulley block (20), a movable pulley block (30) and a steel wire rope (40). The steel wire rope is wound on the fixed pulley block and the movable pulley block and divided by the fixed pulley block and the movable pulley block into a left rope section (410) and a right rope section (420). The crane further comprises a hoisting angle detector (10). The detector comprises a swing frame (110) and a swing angle measuring module (140) installed on the swing frame. The upper end of the swing frame is connected to a pulley shaft (210) of the fixed pulley block in a pivoted mode. The lower end of the swing frame abuts against the left rope section and the right rope section so that the swing frame can be driven by the steel wire rope to swing around the pulley shaft. By means of the detecting device, the hoisting angle of the crane can be accurately measured, and therefore more reference information is provided for operators, and operating risks are greatly reduced.
Description
Technical field [0001] The present disclosure relates to the field of cranes, and in particular, to a crane hoisting angle detection device and a crane with the detection device. Background technique [0002] Vertical hoisting (the hoisting wire rope is vertical) is the basic requirement of crane safe operation, but the crane itself does not have the display and monitoring equipment for vertical hoisting. There are many special working conditions that cannot be achieved vertical lifting, and can only be tilted according to the operator's subjective judgment. In addition, two-machine hoisting and single-machine hoisting are both basic crane operations. Two-machine hoisting is risky. Analysis of the risk of double-machine hoisting found that the main source of the crane load is abnormal changes and non-vertical hoisting. The reason is different from the lifting. Knowing the lifting dynamic information of the other party is related to not being able to grasp the lifting angle of on...
