Embodiment

[0037] Please refer to figure 1 , figure 1 A schematic structural view of the pendulum angle measuring device 100 is shown in . It can be seen from the figure that the swing angle measuring device 100 includes a limiter 110, an angle sensor 120, a support 130 and a connecting piece 140, and the connecting piece 140 is a hinged four-bar mechanism (further, a parallelogram mechanism). The support 130 is fixed, and the connecting piece 140 is hinged to the support 130 . The angle sensor 120 is disposed at the hinge of the connecting piece 140 and the support 130 for detecting the rotation angle of the connecting piece 140 . The limiter 110 is rotatably connected with the connecting member 140 . The limiter 110 defines a limit space 111 for the rope 210 to slide through. The rotation axis of the connecting member 140 is parallel to the rotation axis of the limiter 110 .

[0038]In the present embodiment of the present invention, there are two supports 130, and the connecting ...

Abstract

The invention relates to the field of measuring and hoisting, in particular to a swinging angle measuring device and hoisting equipment. The swinging angle measuring device comprises a limiter, an angle sensor, a support and a connecting piece, wherein the support is fixedly arranged; the connecting piece is hinged with the support; the angle sensor is arranged at the hinged position of the connecting piece and the support, and is used for detecting the rotating angle of the connecting piece; the limiter is rotatably connected with the connecting piece; the limiter limits a limiting space allowing a rope to pass through in a sliding way; and the rotating axis of the connecting piece is parallel with the rotating axis of the limiter. The swinging angle measuring device can measure the swinging angel of a hoisting tool rope simply and conveniently. The hoisting equipment comprises the rope and the swinging angle measuring device. The rope can pass through the limiting space freely in a sliding way. The hoisting equipment can detect the swinging angle of the rope through the swinging angle measuring device so as to ensure hoisting and / or craning accuracy.

Description

technical field [0001] The invention relates to the field of measurement and hoisting, in particular to a pendulum angle measuring device and hoisting equipment. Background technique [0002] Hoisting equipment such as cranes, double-lifting double-sling bridges, etc. use wire ropes as connectors to connect the driving equipment to the spreader, but the flexibility of the wire rope makes the wire rope swing when the spreader of the hoisting equipment lifts heavy objects. , so it becomes very necessary to prevent the rope from swinging in a large range by measuring the swing angle of the wire rope. [0003] In the prior art, laser measurement is mainly used to measure the swing angle of the rope, and the purchase and maintenance costs are very high. The installation and calibration procedure is complicated. Contents of the invention [0004] The object of the present invention is to provide a swing angle measuring device, which can conveniently measure the swing angle of ...
