Embodiment Construction

[0033] 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.

[0034] In the present invention, unless otherwise stated, the used orientation words such as "up, down, left, and right" generally refer to up, down, left, and right in the drawings.

[0035] see Figure 1 to Figure 3 , The invention relates to a swing angle measuring device, which is used for measuring the swing angle of a suspension rope for suspending heavy objects, so as to control the suspension rope according to the measured swing angle, so as to realize stable hoisting operation. In the present invention, the swing angle measuring device mainly includes a support 1, a first rotating shaft 2, a second rotating shaft 3, a follower bracket 4, a first detect...

Abstract

The invention discloses a swing angle measurement apparatus and a hoisting machine equipped with the swing angle measurement apparatus. The swing angle measurement apparatus is used for measuring the swing angle of a lifting rope suspending a heavy object and comprises a support, a first rotating shaft, a second rotating shaft, a follow-up support, a first detector used for detecting the rotation angle of the first rotating shaft and a second detector used for detecting the rotation angle of the second rotating shaft, wherein the first rotating shaft is rotatably mounted on the support, the second rotating shaft is relatively rotatably arranged on the first rotating shaft, the rotation axis of the first rotating shaft and the rotation axis of the second rotating shaft are perpendicular or almost perpendicular, one end of the follow-up support is connected with the second rotating shaft, and the other end of the follow-up support is connected with the lifting rope. According to the invention, the follow-up support connected with the lifting rope is arranged on the second rotating shaft on the first rotating shaft, and the swing angle of the lifting rope is obtained by detecting the rotation angles of the perpendicular first and second rotating shafts and carrying out related calculation; and the swing angle measurement apparatus has the advantages of a simple structure, convenience in installation, etc.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a swing angle measuring device and a hoist equipped with the swing angle measuring device. Background technique [0002] During the hoisting process of large offshore platform hoisting machinery or port hoisting machinery, due to wind and waves, jib rotation and pitching, etc., the hoisting weight will sway obviously. When the swing range is large, it is not conducive to fast and stable completion. Lifting tasks affect work efficiency. Therefore, it is very necessary to measure the swing angle of the hoist in real time. On the one hand, we can understand the general motion law of the swing angle of the hoist, and on the other hand, we can lay the foundation for real-time control of the swing of the hoist. [0003] In the prior art, a structure for measuring the swing angle of the hoisting weight is to place two sets of orthogonal high-speed laser scanners on the top of the s...
