Telecommunication and position detection device of overhead and gantry crane

Abstract

The invention relates to a telecommunication and position detection device of an overhead and gantry crane. The device comprises a trolley, an optical cable winding drum, trolley operating tracks, a trolley position detection device, a trolley connecting device and a trolley control device, wherein the optical cable winding drum, the trolley position detection device, the trolley connecting device and the trolley control device are arranged on the trolley; the trolley operation tracks are two-way constraint tracks parallel to a crane cart; the trolley is supported by trolley wheels to travel on the operating tracks; the connecting device is used for connecting the crane cart, the trolley position detection device is used for detecting the position of the trolley, the trolley control device is used for controlling movement of the trolley; the optical cable winding drum is wound with an optical cable, and two ends of the optical cable are connected with the crane and a remote central control room respectively. The telecommunication and position detection device of the overhead and gantry crane has the advantages as follows: reliable communication between the remote central control room and the in-situ crane is realized; the problems of bandwidth limitation and poor stability of communication are solved; the problem about optical cable collection and release controlled through communication is solved; accurate position measurement of the crane cart is realized, and accurate data are provided for automatic positioning of the cart.

Description

technical field [0001] The invention belongs to a communication and position detection device of a crane, in particular to a remote communication and position detection device of a bridge-gate crane. Background technique [0002] At present, more and more bridge and gantry cranes need to communicate with the rear central control room to transmit relevant video, control signals and position signals on the crane, and even allow operators to remotely operate the crane through real-time video in the central control room. A large number of video and control signals Stable real-time transmission is required, and the commonly used remote communication methods are as follows: (1) Wireless communication methods, whether it is WIFI technology, or 3G, 4G transmission, the current wireless communication bandwidth and reliability cannot meet the clear and stable video signal of the camera on the crane (2) Wired transmission, generally using optical fiber communication, data transmission ...
