The mobile device automatic stopping safety guard of trolley safe in utilization of the present invention, comprise the trolley conductor, the trolley sheath, current-collector, current-collector carbon brush sheet and the circuit breaker that has shunted exciter tripping, also comprise insulation spacing block and shorting switch, the insulation spacing block that shape of cross section is consistent with trolley conductors cross shape is installed at least one phase trolley of the extreme position that mobile device moves conductor, by the insulation spacing block trolley conductor insulation being isolated becomes extreme position forward part and extreme position rear section, by connecting by shorting switch, the extreme position rear section is connected with the shunt opening trip coil of circuit breaker by the dropout switch between extreme position forward part and the extreme position rear section; The longitudinal length of described insulation spacing block is less than the longitudinal length of current-collector carbon brush sheet.
Further, the function of described dropout switch and shorting switch is realized that by an automatic air-break switch auxiliary contact of controlling air switch automatically is the dropout switch;
Further, describedly an insulation spacing block only is installed on the phase trolley conductor at the mobile device moving limit position;
Further, the extreme position rear section of described trolley is fixed by bolt and trolley sheath;
Further, the longitudinal length of described insulation spacing block is 1/3 of a current-collector carbon brush sheet longitudinal length;
Further, the material of described insulation spacing block is a nylon.
The invention has the beneficial effects as follows: the mobile device automatic stopping safety guard of trolley safe in utilization of the present invention, adopt the insulation spacing block that the circuit breaker shunted exciter tripping is controlled, thereby effectively controlling mobile equipment stops, and be convenient to resume operation, have and install simply, reliable for effect, the characteristics that expense is cheap, avoid occurring under the travelling wheel substantial equipment accidents such as road, eliminate safe hidden trouble, reduce maintenance cost; The function of dropout switch and shorting switch is realized by a bidirectional switch, further makes compact conformation of the present invention, and cut install simple and convenient; Extreme position forward part and extreme position rear section are fixed by bolt and trolley sheath respectively, prevent that mobile device two directions when operation trolley conductor and insulation spacing block are moved and influence equipment operation.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 be Fig. 1 along A-A to profile.
Embodiment
Fig. 1 is a structural representation of the present invention, Fig. 2 be Fig. 1 along A-A to profile, as shown in the figure: the mobile device automatic stopping safety guard of the trolley safe in utilization of present embodiment, comprise trolley conductor 2, trolley sheath 1, current-collector, current-collector carbon brush sheet 3 and have shunted exciter tripping circuit breaker 7, comprise that also material is the insulation spacing block 4 and the shorting switch 8 of nylon, the insulation spacing block 4 that shape of cross section is consistent with trolley conductor 2 shape of cross sections is installed on mobile device moving limit position one phase trolley conductor 2, by insulation spacing block 4 the 2 insulation isolation of trolley conductor are become extreme position forward part 21 and extreme position rear section 22, the extreme position rear section 22 of trolley is fixing with trolley sheath 1 by bolt 6, and extreme position rear section 22 and insulation spacing block 4 are moved and influence equipment operation when preventing the operation of mobile device positive direction; Connect by passing through shorting switch 8 between extreme position forward part 21 and the extreme position rear section 22, extreme position rear section 22 is connected with the shunt opening trip coil 9 of circuit breaker 7 by dropout switch 5, the function of shorting switch 8 and dropout switch 5 is by a control air switch realization automatically, automatically the auxiliary contact of control air switch is a dropout switch 5, make the apparatus structure compactness, save installation cost; The longitudinal length of described insulation spacing block 4 is 1/3 of current-collector carbon brush sheet 3 longitudinal lengths, when saving cost, and makes insulation control respond well.
Certainly, the function of shorting switch 8 and dropout switch 5 is not limited to also can be provided with respectively by a control air switch realization automatically; The material of insulation spacing block 4 also is not limited to nylon, also can be other insulating material; Insulation spacing block 4 also is not limited on mobile device moving limit position one phase trolley conductor 2 to be installed, and can realize purpose of the present invention.
When this device uses, when mobile device moves to extreme position, the carbon brush sheet 3 of current-collector slips over insulation spacing block 4, enter uncharged extreme position rear section 22, because the length of insulation spacing block 3 is less than the length of carbon brush sheet 4, the trolley conductor moment energising of extreme position rear section 22, connect the shunt opening trip coil 9 of circuit breaker 7, cause circuit breaker 7 separating brakes, extreme position forward part 21 and extreme position rear section 22 trolley conductors lose power supply, mobile device loses driving power, stops automatically, and the brake dead electricity is held braked wheel tightly simultaneously.
When mobile device need return operation, shorting switch 8 closes, dropout switch 5 as the automatic air-break switch auxiliary contact disconnects, the shunted exciter tripping loop of circuit breaker 7 disconnects, power turn-on circuit breaker 7, the extreme position forward part 21 of trolley conductor 2 and 22 energisings of extreme position rear section, mobile device can start operation.After mobile device moves to extreme position forward part 21, disconnect shorting switch 8, the equipment normal operation input.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
