Bolt installation equipment and method

The invention provides bolt mounting equipment which comprises a controller, a hydraulic pump and a bolt mounting device which are sequentially connected, and the bolt mounting device comprises an axial force measurer, a hydraulic control module and a hydraulic wrench, the axial force measurer is connected with the controller and is used for measuring the axial force in real time when the bolt is mounted and feeding back the axial force to the controller; the hydraulic control module comprises a proportional valve, and the proportional valve is connected with the hydraulic pump, the controller and the hydraulic wrench and used for controlling hydraulic pressure applied to the hydraulic wrench by the hydraulic pump. The axial force measurer measures the axial force of the bolt in real time and feeds back the axial force to the controller, the controller calculates according to the axial force of the bolt and then transmits a signal to the proportional valve, hydraulic pressure is adjusted and output through th
