Abstract
A remote controller starting apparatus for mining magnetic starter mainly comprises an outer shell, a constant-open reed switch, a constant-close reed switch and a magnetic ring. The outer shell comprises an upper cover and a shell. A blind hole is arranged on outer surface of the upper cover. The position of the blind hole is opposite to the reed switch in the outer shell. The shape of the blind hole is corresponding with a permanent magnet of the magnetic ring, wherein, the permanent magnet is used to control the on an off of the reed switch. The cable is introduced from the connecting port of the shell to connect with a control loop of a controlled magnetic starter. The constant-open and the constant-close reed switch are used to act as the constant-open button switch and the constant-close button switch for mining duplex button. The starting apparatus makes use of the principle of action of the reed switch coming across the magnetic spring patch. The magnetic ring is used for controlling the outer surface of the outer shell without mechanical operation on the button control rod, thereby avoiding explosion phenomenon and realizing operation by special person. The utility model has the advantages of simple structure, convenient operation, reliable safety and lightweight.

Background technology
At present, under coal mine, have an explosion gas environment, the mining magnetic starter that plant equipment such as drag conveyor, rubber conveyer, raking loader are far controlled usefulness is far controlled starting device, generally is to use flame-proof mine duplex push-button switch, as: LA81-2 type, ZBA-2 type etc.Subsurface environment is very abominable, there are potential hazards such as coal dust, gas, top board and mine water, there is following adverse effect in the duplex button that the scene is used: the one, because the Fraquent start of equipment and stopping, make that the abrasion at the flameproof gap place between button control bar and flameproof enclosure panel is serious, flameproof gap strengthens, and it is quick-fried easily to cause button to lose.Also cause the intrusion of moisture simultaneously easily, make ponding in the button explosion-proof chamber.The 2nd, the intrusion of fine particles such as coal dust, coal dust increases the frictional resistance at flameproof gap place between button control bar and housing face-plate, and button recoil of spring resistance strengthens, and can not in time reset, and easily causes dynamo-electric accident.The 3rd, because button is hit in the spoil inbreak of top board or the generation of wall caving easily, thus the contingency that the personnel that cause that lie dormant injure.The 4th, everybody can operate the present duplex button that uses, and is unfavorable for the dedicated driver operational administrative, has certain hidden danger on safety.The 5th, flame proof button volume is bigger, and weight is heavier, moves inconvenience, and the wiring horn mouth is easily loosening, influences Plant in good condition.
Summary of the invention
For overcome existing mine explosion-suppression duplex button easily produce lose quick-fried, be unfavorable for full-time administrative, easily cause deficiencies such as misoperation, heaviness, the utility model provides a kind of mining magnetic starter far to control starting device, and this starting device is simple in structure, and is easy to operate, safe and reliable, in light weight.
The technical scheme that its technical problem that solves the utility model adopts is:
The mining magnetic starter that the connection jaws that outgoing cable is used on by the normal open switch in shell, the shell and normally closed switch, shell constitutes is far controlled in the starting device, and its shell is the nonferromugnetic material shell.Normal open switch in the shell and normally closed switch adopt respectively often opens tongue tube, normally closed tongue tube.Be provided with the permanent magnet that control tongue tube break-make is used outside the shell.Have on the outer surface of the loam cake of shell and the control corresponding blind hole of permanent magnet shape.
The technical scheme that its technical problem that solves the utility model adopts can also be:
Permanent magnet and finger ring that mining magnetic starter is far controlled starting device are made one, constitute the magnetic ring.
The utility model compared with prior art has following advantage:
When 1. this starting device shell adopted aluminium mass shell body, its weight was equivalent to 1/20th of mine explosion-suppression duplex button, has light and convenience operation.
2. this starting device is met the principle that the magnetic red sheet moves according to tongue tube, implements start and stop control with the magnetic ring at outer surface of outer cover, does not need the mechanically actuated operation of button control bar, thereby has avoided losing the generation of quick-fried phenomenon.
3. because the unlatching of this device control is to finish by the permanent magnet of definite shape, avoided being subjected to other staff to operate and the machine that opens by mistake causes the generation of personnel's accident with the collision of external force, be convenient to realize the personal management, improve the fail safe of operation of equipment.
4. simple in structure, easy to operate, safe and reliable.
