Embodiment Construction

[0040] based on the following Figure 1 to Figure 8 , specifically describe the preferred embodiment of the present invention.

[0041] Such as figure 1 Shown is a schematic structural view of a bridge crane with double spreaders provided in the embodiment. The double-sling bridge crane includes a cart 23 and a trolley mechanism 1 on the cart 23 . The trolley mechanism 1 is used as a carrier and a platform for equipment construction, and has a moving mechanism 4 and driving mechanisms 2 and 3 . The cart 23 has a drive mechanism 5 . The double-slinger bridge crane includes two independent and interlockable spreaders 6 and 7, which are connected to the driving mechanism 2 and 3 of the trolley mechanism 1 through lifting ropes 8 and 9, respectively. The double-sling bridge crane also includes a swing angle detection device 10 and a rope length detection device, the swing angle detection device 10 is used to detect the swing angle of the bridge crane, and the rope length detec...

Abstract

The invention discloses a bridge crane swing angle and rope length detection device and method. A swing angle detection device is used for obtaining the magnetic flux variation generated along with swing of a lifting rope, the swing angle is obtained through calculation, a rope length detection device is used for obtaining the magnetic flux variation generated along with lifting of the lifting rope, and the rope length is obtained through calculation. The device is simple in structure, convenient to maintain and capable of accurately measuring the swing angle and the rope length.

Description

technical field [0001] The invention relates to a bridge crane swing angle and rope length detection device and detection method. Background technique [0002] The recovery of the world economy and the development of international trade have promoted the development of shipping, which also puts forward higher requirements for the loading and unloading efficiency of container terminals, and intelligence is also increasingly applied to container terminals. However, the traditional single-spreader cranes cannot meet the loading and unloading efficiency requirements of container ports, so multi-spreader container cranes (quay cranes and yard cranes) emerged as the times require. Combined with intelligent equipment, the loading and unloading efficiency of the multi-spreader container bridge crane is greatly improved. [0003] The current multi-spreader bridge cranes are mainly double-slinger bridge cranes, which are a new type of container port handling machinery. Since the dou...
