Abstract
Provided is an explosion-proof type starter used for mining. The explosion-proof type starter comprises an explosion-proof box which is arranged on a pedestal and a junction box which is arranged on the explosion-proof box. The explosion-proof box is provided with a door cover. The explosion-proof box is internally provided with a master control chamber which is internally provided with an isolation commutation switch. The side wall of the explosion-proof box is provided with a rotating handle which is connected with the isolation commutation switch via a rotating shaft. The lower part of the rotating handle is provided with a start button and a stop button. The stop button is close to the rotating shaft, and the rotating shaft is provided with a cam. A U-shaped support, which is fixed on the explosion-proof box, is arranged between the door cover and the cam. The U-shaped support is provided with a connecting rod. The U-shaped support is internally provided with a spring which is sleeved on the connecting rod. The internal end of the connecting rod elastically abuts against the side wall of the cam via the spring, and the external end of the connecting rod is provided with a blocking sheet. The explosion-proof type starter used for mining has advantages of being light in weight, small in size, high in breaking capacity, low in noise, invisible in arc, safe and reliable, etc. Besides, an automatic locking function is adopted, and relevant circuits of a motor are comprehensively protected simultaneously.
Description
Technical field
The utility model relates to a kind of starter for mine, is specially a kind of flame-proof mine starter.
Background technology
Starter for mine is a kind of novel motor control switch, is mainly used under coal mine, the control of motor in the adverse circumstances such as open coal mine, metallurgical mine, port and pier, coal preparation plant, power plant.But the mining flame-proof vacuum electromagnetic starter that the electric equipment in China's coal-mine down-hole, particularly getting working face use is when uncapping maintenance, and the repeatedly accident of live line working actuation gas occurred in down-hole.What China was used at present is electromagnetic starter, under the charged condition of wire connection cavity terminal, just can arbitrarily open, and easily produces electric spark, actuation gas.
Utility model content
The technical problem that the utility model solves is to provide a kind of flame-proof mine starter, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Flame-proof mine starter, comprise the Flameproof box being arranged on base and be arranged on the junction box on Flameproof box, Flameproof box is provided with door closure, in Flameproof box, be provided with master control chamber, described master control is provided with isolation reversing switch in chamber, sidewall on Flameproof box is provided with the turning handle of controlling isolation reversing switch, described turning handle is connected with isolation reversing switch by rotating shaft, turning handle bottom is provided with start button and the stop button of controlling auxiliary relay, described stop button is near rotating shaft, described rotating shaft is provided with cam, stop button below is provided with contact chip, described contact chip is provided with the alignment pin being connected with cam, between door closure and cam, be provided with the U-shaped support being fixed on Flameproof box, on described U-shaped support, connecting rod is installed, in U-shaped support, be provided with the spring being sleeved on connecting rod, connecting rod the inner by spring be against with cam sidewall on, connecting rod outer end is provided with catch.
Further, on the connecting rod between the biside plate of U-shaped support, be fixed with banking stop, spring is between the front side board and banking stop of U-shaped support.
In the utility model, cam and contact chip, cam and connecting rod form duplex lock structure.
The beneficial effects of the utility model are: the utlity model has lightweightly, volume is little, and breaking capacity is large, and noise is low, and electric arc do not expose, the advantage such as safe and reliable; Adopt automatic blocking function, motor circuits is carried out to integrated protection simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model duplex lock.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1, shown in Fig. 2, flame-proof mine starter, comprise the Flameproof box 2 being arranged on base 1 and be arranged on the junction box 3 on Flameproof box 2, Flameproof box 2 is provided with door closure 4, in Flameproof box, be provided with master control chamber, described master control is provided with isolation reversing switch in chamber, sidewall on Flameproof box 2 is provided with the turning handle 5 of controlling isolation reversing switch, described turning handle 5 is connected with isolation reversing switch by rotating shaft 6, turning handle 5 bottoms are provided with start button 7 and the stop button 8 of controlling auxiliary relay, described stop button 8 is near rotating shaft 6, described rotating shaft 6 is provided with cam 9, stop button 8 belows are provided with contact chip 10, described contact chip 10 is provided with the alignment pin 11 being connected with cam 9, between door closure 4 and cam 9, be provided with the U-shaped support 12 being fixed on Flameproof box 3, on described U-shaped support 12, connecting rod 13 is installed, in U-shaped support 12, be provided with the spring 14 being sleeved on connecting rod 13, connecting rod 13 the inners by spring be against with cam 9 sidewalls on, connecting rod 13 outer ends are provided with catch 15.On the connecting rod between the biside plate of U-shaped support, be fixed with banking stop 16, spring 14 is between the front side board 17 and banking stop 16 of U-shaped support.
In the utility model, described turning handle 5 is in order to disjunction and close isolation reversing switch or commutation, stop button 8 and isolation reversing switch handle interlocking, after only having stop button 8 to press, the alignment pin 11 on contact chip 10 departs from cam 9, and isolation reversing switch can rotate, door closure 4 is interlocked with the turning handle 5 of isolation reversing switch, when isolation reversing switch is closed, can not opens and cover 4, only have when the turning handle 5 use screw locks that rotate reversing switch are during in disjunction position, just can open door closure 4.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
