Control device 13 control cutting arms 11 are to use contactor directly to control, and just directly start cutting arm 11 as long as no electric fault generally speaking.But Working Environment of Underground Mine is complicated abominable, in the situation that work plane sight line lack of defination, directly start cutting motor 14, cutterhead 111 rotary speeies and moment of torsion are all very large, in case the constructor is arranged in the development machine forward operation, as easy as rolling off a log being rolled by cutterhead 111 and cause mortal injury.
Summary of the invention
Purpose of the present invention provides development machine, and this development machine can avoid having higher safety because maloperation damages the men at work.
The present invention discloses a kind of development machine, this development machine comprises cutting arm and fuselage, the cutting arm front end is provided with cutterhead, the built-in control device of fuselage, control device is by the action of cutting motor control cutting arm, be provided with infrared sensor on the described cutting arm, described infrared sensor is connected with described control device; Described infrared sensor detects infrared signal, is sent to described control device, the described cutting motor of described control device locking.
Preferably, described infrared sensor is two, is separately positioned on the cutting arm left and right sides.
Preferably, described infrared sensor is embedded in the described cutting arm left and right sides.
Preferably, the external surface of the described cutting arm left and right sides is respectively equipped with mount pad, and described infrared sensor is arranged in the described mount pad.
Preferably, infrared sensor is connected with described control device and is specially: described infrared sensor is connected with described control device by isolator.
Preferably, first relay of described control device by series connection be connected relay and be connected with described cutting motor.
Preferably, the described cutting motor of described control device locking is specially: described control device disconnects the first relay and the second relay.
Compared with prior art, the present invention has the following advantages:
Whether infrared sensor detects the place ahead the constructor, if any, infrared sensor generates induced signal and sends to control device, control device is converted to control instruction with this induced signal, the locking cutting motor, make cutting arm can not start or stop operation, the men at work is damaged avoiding.
Description of drawings
Fig. 1 is existing development machine schematic diagram;
Fig. 2 is development machine schematic diagram of the present invention;
Fig. 3 is development machine control system schematic diagram of the present invention.
The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, development machine schematic diagram of the present invention is shown, this development machine comprises cutting arm 11 and fuselage 12, cutting arm 11 front ends are provided with cutterhead 111, fuselage 12 built-in control device 13, control device 13 is by 11 actions of cutting motor 14 control cutting arms.Be provided with infrared sensor 15 on the cutting arm 11, infrared sensor 15 is connected with control device 13.
During work, whether infrared sensor 15 detects the place ahead the constructor, if any, infrared sensor 15 generates induced signal and sends to control device 13, control device 13 is converted to control instruction with this induced signal, locking cutting motor 14 makes cutting arm 11 can not start or stop operation, the men at work is damaged avoiding.
Like this, even this development machine is various in constructor's work post, insufficient light, work under the environment of the larger grade of noise inclement condition (such as the mining face under mine in colliery), can accurately detect development machine the place ahead such as infrared sensor 15 whether the constructor is arranged, avoid only relying on operating personnel to observe and cause error, the generation of minimizing accident.
For enlarging the detection range of infrared sensor 15, the present invention can each side arrange an infrared sensor 15 at cutting arm 11, makes the detection range of infrared sensor 15 surpass 180 degree, enlarges detection range, improves inspecting force.
For the foreign material that not stirred by development machine when work of protection infrared sensor 15 damage, infrared sensor 15 is embedded in the left and right sides of cutting arm 11.Cutting arm 11 each side arranges a groove, and two infrared sensors 15 are fixedly mounted in the groove respectively.So namely do not affect cutting arm 11 actions, also protect infrared sensor 15, prolong the application life of infrared sensor 15.
Certainly, the present invention also can each side arrange a mount pad at cutting arm 11, and two infrared sensors 15 are fixedly mounted in the mount pad respectively.
Referring to Fig. 3, development machine control system schematic diagram of the present invention is shown, comprise power supply 16, the first infrared sensors 151, the second infrared sensor 152, isolator 17, control device 13, the first relay 181, the second relay 182 and cutting motor 14.
Power supply 16 provides power supply for the first infrared sensor 151 and the second infrared sensor 152, the first infrared sensor 151 and the second infrared sensor 152 are connected to two inputs of isolator 17, two outputs of isolator 17 are connected to the input of control device 13, first relay 181 of the output of control device 13 by series connection be connected relay 182 and connect cutting motors 14.
During the development machine normal operation, the first relay 181 is connected, and control device 13 is by the start and stop that turn on and off control cutting motor 14 of the second relay 183, and then the action of control cutting arm 11.When the first infrared sensor 151 and/or the second infrared sensor 152 transmission actuated signal control devices 13, control device 13 turn-offs the first relay 181, the control loop of locking development machine simultaneously.Even at this moment operating personnel press start button, connect the second relay 182, still can not start cutting motor 14, prevent cutting arm 11 misoperations, the injury constructor.
Control device 13 of the present invention also can turn-off the first relay 181 and the second relay 182 simultaneously when receiving induced signal, form duplicate protection, increases safety factor.
Certainly, control device 13 also can by the first in parallel relay 181 be connected relay 182 and be connected with cutting motor 14.Control device 13 turn-offs the first relay 181 and the second relay 182 simultaneously when receiving induced signal.
The present invention arranges isolator 17 between infrared sensor 15 and control device 18, avoid infrared sensor 15 to be subject to strong jamming after, interfering signal is damaged control device 13,13 safe operations of protection control device.
The above only is preferred embodiment of the present invention, does not consist of the restriction to protection domain of the present invention.Any any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
