Description
Technical field
The utility model relates to the twin-roll electrical haulage shearer remote control system of coal mine fully-mechanized mining working, relate in particular to MG450/1020-WD type electrical haulage shearer and isonomic twin-roll electrical haulage shearer remote control system thereof, be specially a kind of Novel electric haulage shearer remote control.
Background technology
MG450/1020-WD type electrical haulage shearer is a kind of double-ended shearer that Tiandi science and technology Co., Ltd produces.Be applicable to coal seam thickness 2-4.5m, ature of coal hard or in hard long-armed fully-mechanized mining working, support the use with working face conveyor, hydraulic support etc., can realize the mechanization of adopting, fill, transporting.
Use discovery through reality, the remote control that MG450/1020-WD type and homologous series electrical haulage shearer thereof are joined, its result of use can not satisfy the requirement of execute-in-place, and standard configuration remote controller volume is large, need the corresponding job key of bimanualness during use, very inconvenient, therefore fail to come into operation always.To realize the traction of coal-winning machine and the lifting of rocking arm by modes such as control stations, termination in actual production process.During the coal-winning machine coal cutting, the coal mining driver need follow coal-winning machine and walk before frame in this case, and the coal-winning machine driver is between hydraulic support and the fuselage, is vulnerable to come from the threat that inclined to one side side and support maloperation bring.
After finding also at work that in addition former remote controller sends instruction, the remote-receiver effect is undesirable, coal-winning machine can not be made corresponding action, especially when coal-winning machine runs to front slide tail, because unit revolution cable and water pipe blocking antenna, remote controller often occurs and can not effectively control the problem of coal-winning machine, also there is certain safety in production hidden danger in the running that so not only affects coal-winning machine.
Specifically summing up the problem that MG450/1020-WD type and homologous series electrical haulage shearer thereof have comprises:
(1) efficient working range of coal-winning machine remote-receiver is little, and the coal-winning machine action is insensitive.
What the original device remote-receiver adopted is the SYV75-541 radio-frequency cable, and one terminates on the PA2 remote control reception box, and the other end pulls out insulated hull and exposes bare copper wire, is fixed on the hand hydraulicchange-over valve place in coal-winning machine front.Antenna Design is simple and crude, and corrosion easily occurs exposed copper cash, affects reception, is subjected to the humorous wave interference of unit frequency-conversion device in addition, causes the remote control efficient working range to diminish, and moves insensitively, easily causes the accident.Use through reality and to record: effective radius of clean-up of actual remote control is 5m.
(2) remote controller standard configuration electric weight is low can not meet the demands, and affects functional performance.
Original device remote controller standard configuration adopts No. 5 alkaline rechargeable batteries of two joints, capacity 300mAh, voltage 3V.Battery capacity is little, is not enough to keep the use of the class of production, and along with the decay of the electric weight in using a teleswitch, effective control range of remote controller further reduces, so that can not normally use.
Summary of the invention
The utility model provides a kind of Novel electric haulage shearer remote control in order to solve existing MG450/1020-WD type and homologous series electrical haulage shearer efficient working range is little, the working time is short problem thereof.
The utility model is concrete to adopt following technical scheme to realize:
Novel electric haulage shearer remote control, comprise remote controller and remote-receiver, described remote-receiver comprises PA2 remote control reception box, draw trunk cable and be branched off into two receiving terminals through mine intrinsic safety four-way junction box from PA2 remote control reception box, two receiving terminals respectively are connected with special-purpose shortening type antenna by two way junction boxes; Described two way junction boxes are fixed in the protective jacket that iron plate makes, and are provided with circular hole on the protective jacket, and special-purpose shortening type antenna connects and stretches out circular hole behind the dual-purpose junction box and fixedly do external antenna; Remote controller uses lithium battery.
Described mine intrinsic safety four-way junction box can adopt JHH-2 type distributing box for mine substantial security circuit.Described PA2 remote control reception box and trunk cable between the mine intrinsic safety four-way junction box have adopted the MSLYFYUZ-75-9 type leaky cable of communicating by letter, and two branch lines telling through mine intrinsic safety four-way junction box have adopted the SYV75-5.41 radio-frequency cable.Protective jacket plays protective action.
Remote controller is replaced by lithium battery capacious with original alkaline rechargeable battery, to improve the remote controller effective time.
Compare with existing equipment, the external antenna that the utility model is drawn by two-way branch, effectively avoided the interference of coal-winning machine frequency converter, the shortening type antenna Effective Raise that adopts receiving sensitivity, the effective radius of clean-up that makes remote control is brought up to 15m after the improvement by original 5m, operating personnel can be in larger effective range the normal operating coal-winning machine, can guarantee again staff's safety.Simultaneously on the basis of original remote controller, alkaline rechargeable battery is replaced by lithium battery capacious, has improved the effective time of remote controller.
