The invention provides a nut tightening device which comprises a positioning rod capable of being positioned to any position in space, a nut sleeve located at the end of the positioning rod, a visualsensor located on the positioning rod and used for shooting towards the direction of the nut sleeve, an electric wrench fixed to the positioning rod and used for driving the nut sleeve to rotate, anda control system, wherein a nut can be sleeved with the nut sleeve. The control system is used for driving the positioning rod to move based on an image shot by the visual sensor to enable the nut sleeve to sleeve the nut and also used for driving the electric wrench to rotate when the nut is sleeved with the nut sleeve so as to further drive the nut sleeve to rotate, and thus the nut is screwed on a screw rod.

The invention relates to an electric-control mechanical stepless row spacing regulator for a seeder. The electric-control mechanical stepless row spacing regulator comprises a tank body, and a power input device, a power output device, a transmission device, a regulating device, a plurality of sets of oscillating bar reset devices, a limiting device, a displacement detection device and a row spacing indicating device which are arranged in the tank body. The row spacing regulator is characterized in that the power input device comprises an input shaft, a spacer sleeve I and a plurality of cams spaced at a certain angle, two guide racks are arranged in the middle of two ends of a regulating rack, the lower end of the regulating rack is provided with oscillating shafts equal to the cams, roller oscillating bars penetrate the oscillating shafts at intervals, one end with a roller of each roller oscillating bar is pressed on the corresponding cam by the corresponding oscillating rod reset device, the other end of each roller oscillating bar is hinged with a clutch housing, a screw worm of the regulating device horizontally penetrates the regulating rack, one end, close to the worm, of the regulating device extends out of the tank body to be connected with a gear motor shaft, and a micro sliding block displacement sensor probe of the displacement detection device is fixed on the regulating rack. The electric-control mechanical stepless row spacing regulator for the seeder can be used for performing stepless regulation on row spacing so as to achieve variable seeding.

An underground working personnel emergency rescue guiding system and a guiding method are provided, so safety management personnel can timely learn about underground personnel distribution conditions, early warning can be timely send to underground people and an effectively escape route can be timely provided for underground personnel when danger happens, thus effectively reducing personnel casualty and economic losses, and improving mine enterprise safety production level; the guiding system comprises a host computer, a fiber communication device, a communication substation, an information miner light, an audible-visual annunciator, an escape guiding screen and a power supply; the guiding method comprises the following steps: the host computer receives people monitoring data from the communication substation through the fiber communication device, and sends short message data, alarm data and escape guiding data to the communication substation; the communication substation sends the short message data to the information miner light, and respectively transfers acousto-optic alarm data and escape guiding data to the audible-visual annunciator and escape guiding screen; the underground working personnel wear the information miner light, send communication codes identifying IDs to the communication substation, and receive the early warning information and the guiding route from the communication substation.
