Embodiment
[0047] The method for calculating the swing amplitude of the hanging object of the cable machine described in the embodiment of the present invention is as follows: figure 1 shown, including the following steps:
[0048] Step S1. Obtain the first real-time swing δ of the cable machine hook 3 relative to the cable machine main cable straight line 1 ;
[0049] Such as figure 2 said, the first real-time swing δ 1 The essence consists of two parts: the real-time swing δ of the cable car trolley 5 relative to the straight line of the cable machine main cable 11 and the real-time swing δ of the cable car hook 3 relative to the cable car trolley 5 12 , the real-time swing δ of the cable car trolley 5 relative to the straight line of the main cable of the cable machine11 is the vertical distance that the cable car trolley 5 deviates from the straight line of the cable machine main cable on the horizontal plane, and the real-time swing δ of the cable car hook 3 relative to the cab...

The present invention relates to the field of cable cranes. The invention aims to solve the problem of low accuracy in some methods for analyzing the swing amplitude of hanging objects in cable cranes, and proposes a method for calculating the swing amplitude of hanging objects in cable cranes, including: obtaining the hooks of cable cranes The first real-time swing relative to the straight line of the main cable of the cable machine; real-time detection of the wind speed, wind direction and air density within the range of the hook of the cable machine, and the first included angle between the wind receiving area and wind direction of the hanging object and the straight line of the main cable of the cable machine and the length of the hook cable; calculate the second real-time swing of the hanger relative to the hook of the cable machine according to the wind speed, wind direction, air density, wind area of the hanger and the first included angle, and according to the first real-time swing and the second real-time swing to calculate the real-time swing of the hanging object relative to the straight line of the main cable of the cable machine. The invention improves the calculation accuracy of the swing amplitude of the hoisted objects of the cable crane, and is suitable for the cable crane running in deep and narrow canyons.
Description
technical field [0001] The invention relates to the technical field of cable machines, in particular to a method for calculating the swing amplitude of objects suspended by a cable machine. Background technique [0002] The cable crane is the main way for concrete dam construction resources to enter the warehouse. Whether the operation of the cable crane is safe is crucial to the construction of the dam project, and it is also a reflection of the management level. In deep and narrow canyons, the operation safety of the cable car is obviously affected by the strong wind. Under the condition of long-term strong wind or instantaneous strong wind, it is very easy to collide with the cable of the cable car or the hanging tank. [0003] In the prior art, the hanging object and the hook are usually regarded as a whole when analyzing the swing amplitude of the hanging object of the cable machine, and the influence of the strong wind on the hanging object is not considered, resultin...
