Description
Technical field
The present invention relates to a kind of development machine, be specifically related to a kind of development machine adaptive speed device, for solving the continuous digging task of development machine.
Background technology
Development machine is to use traditional mode to operate both at home and abroad at present, adopts the manual type direct control fully.Its drawback is that the operator of development machine judges the overload of cutting motor and underload by rule of thumb; Regulate the operation of high speed and low speed cutting motor; Cut high speed and low rate start dwell time are long at interval; Be unfavorable for continuous digging, the waste that excessive underload meeting simultaneously brings resource, excessively overload can the major injury cutting motor.To this drawback, the present invention designs adaptive speed device can solve continuous digging, underload waste, and the problem of overload damage motor is increased work efficiency to greatest extent, improves the degree of mechanical automation.
Summary of the invention
Technical problem to be solved by this invention provides the adaptive speed regulation of a kind of ability, increases work efficiency to greatest extent, improves the development machine adaptive speed device of the degree of mechanical automation.
In order to solve the problems of the technologies described above; Development machine adaptive speed device provided by the invention; Comprise cutting units and electric-control system, described cutting units comprises reductor and double speed cutting motor, and described electric-control system comprises switch-box and control box; Between described reductor and double speed cutting motor, torque sensor is installed, described torque sensor is electrically connected with the controller of described switch-box 20.
Described torque sensor is mine anti-explosion or intrinsically safe equipment.
Described torque sensor directly or through the intrinsic safety isolated gate links to each other with the controller of described switch-box.
Adopt the development machine adaptive speed device of technique scheme, development machine is according to the load condition of the rated power ratio in judgement double speed cutting motor of the torque value of the torque sensor of this device and double speed cutting motor, when the double speed cutting motor is operated in low speed; When performance number and torque value are in underload state; Automatically close slowspeed machine, connect high-speed electric expreess locomotive, when the double speed cutting motor is operated in high speed; When performance number and torque value are in overload condition; Automatically the closing high-speed motor is connected slowspeed machine, realizes the crack conversion continuously of high low speed.When the double speed cutting motor was operated in low speed, performance number and torque value were in overload condition, or the current of electric overcurrent, and during states such as short circuit, this device has corresponding delay protection function.
In sum; The present invention is according to the real-time measurement values of torque sensor and the realtime power value of double speed cutting motor; Self adaptation is regulated the underload raising speed of low speed, is transshipped reduction of speed, low speed overload protection at a high speed, adapts to driving coal mining task continuously, has improved the operating efficiency and the economic worth of development machine.Monitoring cutting motor output torque and power output make the cutting motor work of reliable and stable more in real time, are the adaptive speed regulation of a kind of ability, increase work efficiency to greatest extent, improve the development machine adaptive speed device of the degree of mechanical automation.
