Problems solved by technology
[0003] Because the system fails to predict in time when the tank road is deformed, it is very easy to cause major accidents such as tank jamming or machine crash. In recent years, many coal mines have experienced similar tank jamming due to tank road deformation. , There are also incidents of cages and tanks in some coal mines. Once such a major accident occurs, the direct economic usually ranges from a few million to tens of millions, and there is a very serious safety hazard

The invention discloses a device for measuring and analyzing spacing between steel shaft guides of a vertical shaft and a method for measuring the spacing between the shaft guides, and belongs to the field of coal mine vertical shaft hoisting systems. The device includes a controller installed on a derrick at a shaft mouth, and an upper computer installed on the ground, wherein the controller is connected with laser rangefinders, a singlechip and an LCD through a plurality of serial ports, and is communicated with the upper computer through a wireless communication module; the other end of the singlechip is connected with a photoelectric encoder and a keyboard through an I / O interface; the upper computer is connected with the other end of each laser rangefinder, and is used for reading data information of the laser rangefinders through the serial ports; and the LCD of the controller is connected with a laser displacement sensor and an axial encoder respectively. The invention has the advantages that the horizontal spacing between the shaft guides can be continuously measured when a winch operates at the overhaul speed, the shaft guide deformation can be informed in advance by the system, and the like, so that major accidents such as ruin of an elevator or death caused by shaft guide jamming can be avoided.
Description
technical field [0001] The invention relates to a measuring and analyzing device for the distance between steel tanks in a shaft and a method for measuring the distance between the tanks, belonging to the field of coal mine shaft hoisting systems, and in particular to a monitoring device for measuring the distance between tanks in a shaft of a coal mine shaft and a method for using the same. Background technique [0002] The deformation of shafts in coal mines is mainly manifested in the deflection and deformation of the tank road fixed together with it. The deflection and deformation of the tank road lead to increased lifting resistance and increased wear of tank ears. When this deformation develops to a certain extent, it may occur Accidents of cans stuck or dropped, obviously, it is very necessary to keep track of the deformation of tanks at any time. Therefore, the measurement and analysis system for the distance between shaft steel tanks is an inevitable trend in the dev...
