| titleOfInvention | Height measuring device for caving band of fully mechanized caving face |
| abstract | The utility model relates to a mining technical field provides a combine and put working face caving zone height measurement device. The utility model discloses a device includes pressure monitoring device, signal reception and processing apparatus, signal transmission line, and pressure monitoring device's output is connected with signal reception and processing apparatus's input electricity through signal transmission line, and pressure monitoring device is used for converting the vertical effort of the goaf caving rock that pressure monitoring device received into frequency signal and gives signal reception and processing apparatus, and signal reception and processing apparatus are used for calculating the caving zone height according to frequency signal. The device still includes outside protection device, and pressure monitoring device is the pressure cell, and upper iron plate, lower iron plate all pass through spring coupling in the four corners among the outside protection device, and the pressure cell setting is at last iron plate, down between the iron plate. The utility model discloses can improve and combine the precision and the reduce cost of putting working face falling area height measurement. |
