Description

A kind of electric commutation mechanical structure of flame-proof mine unit switch module

Technical field

The utility model relates to the electric commutation mechanical structure of the full unit switch of a kind of flame-proof mine.

Background technology

The purpose of commutation is through commutation mechanism, with A phase, the B of inlet wire reach mutually C be phase-changed into C phase, B mutually and A mutually.Mostly the commutation mode of flame-proof type switch is the phase-change switch commutation at present.The shortcoming of this structure is: volume is big, leans on dependent manual operation inconvenient, more can not realize each loop independence commutation, and function has limitation during on-the-spot the use.And therefore other common phase changers, are not suitable under mine, using owing to do not possess the flame proof function.

Summary of the invention

The purpose of the utility model is to provide a kind of electric commutation structure that can under mine, use.

In order to achieve the above object; The technical scheme of the utility model has provided a kind of electric commutation mechanical structure of flame-proof mine unit switch module; It is characterized in that: comprise that the seat of honour with circulation cam structure reaches following; In the seat of honour and following, be respectively equipped with a cone pulley, cone pulley is by the commutated motor driven in rotation, on the seat of honour reaches following, is respectively equipped with to be used for and the contacted commutation copper sheet of contact.

Further, outside the output shaft of said commutated motor, be with the travel switch fixed head, travel switch is fixed on the travel switch fixed head, on the output shaft of commutated motor, is provided with the therewith travel switch fore-set of motion.

On said commutation copper sheet, be provided with shell fragment.

On said following, have the groove of one section 1/4 circle, limit assembly inserts in this groove, and limit assembly is fixed on the said switch fixed head.

Said limit assembly comprises contact tube; Middle part at contact tube is wrapped with insulating rod; Between insulating rod and said switch fixed head, be provided with first Wiring nose; One of spacing contact chip terminates on first Wiring nose, and the other end extends to by the contact tube, is provided with second Wiring nose at the end of contact tube.

The electric commutation mechanical structure of a kind of flame-proof mine unit switch module that the utility model provides has adopted motor-driven form, and not only volume is little, and convenient and swift, is highly suitable for underground work.

Fig. 2 is the limit assembly sketch map.

Embodiment

The electric commutation mechanical structure of a kind of flame-proof mine unit switch module that the utility model provides; Comprise that the seat of honour 1 with circulation cam structure reaches following 5; In the seat of honour 1 and following 5, be respectively equipped with a cone pulley 9, cone pulley 9 is by commutated motor 8 driven in rotation, on the seat of honour 1 reaches following 5, is respectively equipped with to be used for and the contacted commutation copper sheet 2 of contact; On commutation copper sheet 2, be provided with shell fragment 3; Outside the output shaft of commutated motor 8, be with travel switch fixed head 14, travel switch 10 is fixed on the travel switch fixed head 14, on the output shaft of commutated motor 8, is provided with the therewith travel switch fore-set 7 of motion.

Simultaneously, on following 5, have the groove of one section 1/4 circle, limit assembly 4 inserts in this groove, and limit assembly 4 is fixed on the said switch fixed head 14.In conjunction with Fig. 2; Limit assembly 4 comprises contact tube 11; Be wrapped with insulating rod 12 at the middle part of contact tube 11, between insulating rod 12 and said switch fixed head 14, be provided with first Wiring nose 13, one of spacing contact chip 10 terminates on first Wiring nose 13; It is other that the other end extends to contact tube 11, is provided with second Wiring nose 15 at the end of contact tube 11.

Cone pulley 9 operate in the seat of honour 1 with following 5 in, the track of its operation is 4 1/4 equal left hand thread and the right-handed thread of pitch, after this screw thread connected successively, chamfered made formation one vertical range between peak and the minimum point again.When assign the commutation order to system through man-machine switch after; Commutated motor 8 drive cone pulleys 9 the seat of honour 1 with following 5 in half-twist; The seat of honour 1 was opened with following in 5 minutes, the turnover contact is had mutually with commutation copper sheet 2 leave, and then the drive seat of honour 1 and following 5 half-twist together.Because limit assembly 4 is inserted in down in annular groove of 1/4 of seat, behind the seat of honour 1 and following 5 half-twists, limit assembly 4 blocks, and makes it can not continue to rotate.At this moment, spacing contact chip 10 contacts with contact tube 11 conductings, makes

first Wiring nose

13 and 15 conductings of second Wiring nose, and the expression commutation puts in place, can the adhesive contactor, and just can not adhesive if commutation is not in place.Simultaneously commutated motor 8 continue to drive cone pulleys 9 the seat of honour 1 with following 5 in the continuation half-twist move to two peak respectively; Travel switch fore-set 7 is run into travel switch 6; Commutated motor 8 is stopped, with the distance shrinkage of the seat of honour 1, compress the turnover contact simultaneously with following 5.A commutation is accomplished, and a commutation of motor is rotated 270 °, and this rotation of 270 ° is continuous, guarantees that commutation could the adhesive contactor after putting in place fully.If give 8 commutation signals of commutated motor again, must be earlier with the contactor separating brake, commutated motor 8 is pressed 270 ° of above-mentioned steps antikinesises then, and the seat of honour 1 and following 5 half-twists.Commutated motor 8 drives contact copper sheet 2 and compresses when passing in and out the line contact, in contact copper sheet 2 bottoms shell fragment 3 is arranged, and will contact copper sheet 2 for 2 one enough elastic force of contact copper sheet and presses round about, guarantees to contact copper sheet 2 and well contacts with turnover line contact.
