Description

technical field [0001] The invention relates to a control device for a peripheral transmission concentrator, in particular to a code synchronization control device for a peripheral transmission concentrator. Background technique [0002] The currently used peripheral drive concentrator mainly scrapes and collects the material in the concentrator tank by lifting rakes in sections, that is, multiple scraping devices that can be lifted independently are installed side by side along the bridge frame of the concentrator. Each scraping device is composed of a rake frame, an oil cylinder, and a synchronous control device. The rake frame is connected to the bridge frame of the concentrator through the corresponding oil cylinder. The synchronous control device adjusts the working height of the rake frame by controlling the expansion and contraction of the piston rod of the oil cylinder. Due to the actual operating environment requirements for scraping and collecting the bottom materi...

Problems solved by technology

However, most of the existing synchronous control devices adopt a multi-point parallel structure, which consists of five or more travel switches arranged up and down and fixed on the cylinder and a movable steel plate parallel to the cylinder and fixed on the piston rod of the cylinder. The difference in the number of stroke switches that the movable steel plate touches with the expansion and contraction of the piston rod of the oil cylinder reflects five or more different height states of the rake frame in the concentration tank, and the synchronous control device is based on actual work needs and refers to the height reflected by the stroke switch The height of the rake frame in the thickening tank is adjusted according to the state. Such a synchronous control device has the following problems: due to the large number of scraping devices installed side by side on the bridge frame of the peripheral transmission thickener, and the synchronous control device of each scraping device If the number of travel switches installed is five or more, the number of travel switches installed on the entire concentrator will be too many; and due to the special requirements of the working environment of the concentrator, the synchronous control device must accurately control the rake height, that is to say, every The position of each travel switch on the corresponding oil cylinder must be accurate, so as to ensure that the height error between rake frames is controlled within the allowable range. It is a very cumbersome job to accurately position so many travel switches on many oil cylinders. Usually, a second adjustment is required; and because the travel switch is exposed to the humid environment on the concentration pool for a long time, it is easy to fail, and if one of the travel switches on the entire thickener fails, the entire thickener will fail, so the number of travel switches Too many will cause a high failure rate of the thickener, especially the thickener with a large number of rake racks is more prominent
