Abstract

The utility model relates to a coal mine technological field, concretely relates to behaviour's car power supply circuit at bottom of auxiliary shaft. The comprehensive guarantor ZBZ -4.0 of single power is taken from to behaviour's car power at the bottom of the auxiliary shaft, combines the lighting system who protects the shunting signal station, combines guarantor's power and takes from 1# electric substation low -voltage distribution cabinet, and comprehensive guarantor when going up the one -level power or combining guarantor's trouble is grasped the car system and is lost the electricity at the bottom of the auxiliary shaft, lead to the unable normally promotion of lifting machine. A behaviour's car power supply circuit at bottom of auxiliary shaft, includes power I, power I's voltage is 24V, power I go up to establish ties and to have master switch SB3, switch SB1, relay KM1, switch SB1 and relay KM1 go up parallelly connected have switch SB2, relay KM2, switch SB1 go up the parallelly connected normally open contact SM1 that has, switch SB2 goes up the parallelly connected normally open contact SM2 that has. The utility model discloses car system power supply's security and stability are ensured to grasp by the circuit, take 1# electric substation low -voltage distribution cabinet to divide the row operation, I, two comprehensive guarantors of stage II shunting provide the power for grasping the car system respectively.

Description

Behaviour's car power circuit at the bottom of a kind of auxiliary shaft

One, technical field:

The utility model relates to technical field of coal mine, is specifically related to grasp car power circuit at the bottom of a kind of auxiliary shaft.

Two, background technology:

Grasp car power supply at the bottom of auxiliary shaft and take from single supply comprehensive guarantor ZBZ-4.0, combine the illuminator of Bao Fenjiexinhaotai, comprehensive power supply of protecting takes from 1# electric substation low-voltage distribution cabinet, when combining guarantor's upper level power supply or combine guarantor's fault, holding tramcar system dead electricity at the bottom of auxiliary shaft, causes elevator cannot normal hoisting.

Three, utility model content:

The utility model, in order to solve the weak point in above-mentioned background technology, provides at the bottom of a kind of auxiliary shaft and grasps car power circuit.

For achieving the above object, the technical solution adopted in the utility model is: grasp car power circuit at the bottom of a kind of auxiliary shaft, comprise power supply I, described power supply I is in series with master switch SB3, switch S B1, relay K M1, described switch S B1 and relay K M1 is parallel with switch S B2, relay K M2, described switch S B1 is parallel with normally opened contact SM1, switch S B2 is parallel with normally opened contact SM2.

The voltage of described power supply I is 24V.

Compared with prior art, the advantage that the utility model has and effect as follows: the utility model circuit guarantees the safety and stability of holding tramcar system power supply, take 1# electric substation low-voltage distribution cabinet fanout operation, I, II section of tap, two comprehensive guarantors are respectively holding tramcar system provides power supply.

Four, accompanying drawing illustrates:

Fig. 1 is circuit diagram of the present utility model;

Five, embodiment:

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:

See Fig. 1: grasp car power circuit at the bottom of a kind of auxiliary shaft, comprise power supply I, described power supply I is in series with master switch SB3, switch S B1, relay K M1, described switch S B1 and relay K M1 is parallel with switch S B2, relay K M2, described switch S B1 is parallel with normally opened contact SM1, switch S B2 is parallel with normally opened contact SM2, the voltage of described power supply I is 24V.

The utility model grasps car 1#, 2# power acquisition KM1, KM2 relay, and SB1, SB2, SB3 button switches, and combine the normally opened contact protected power supply and connect SM1, SM2 respectively, click and often open button SB1, relay K M1 is charged, and it is charged that 1# combines guarantor; Click normally closed button SB3,1# and combine guarantor's dead electricity, then button click SB2, relay K M2 is charged, and it is charged that 2# combines guarantor.

The double loop of the utility model behaviour car power supply ensure that the safety and stability of holding tramcar system, for maintenance repair work provides conveniently, simultaneously for mine safety production is laid a good foundation.

At the bottom of auxiliary shaft, Power supply alteration scheme is simple, and input cost is low, can be generalized to associate organization, guarantees the safety and stability of mine shaft hoist system, for maintenance repair work is provided convenience.
