In the present embodiment, as an example of the mounting means of Fig. 1 example, lift car charging unit of the present invention is described.In the both sides of power supply box, there are respectively a flexible contact and a fixed pulley, on the first flexible contact 18 and first, fixed pulley 17 is responsible for the path of 12V, and on the second flexible contact 14 and second of opposite side, fixed pulley 15 is responsible for the path of 0V.In the time that elevator moves, the electric power of lift car is provided by car power supply part 9, car drives steel rope motion, thereby drive coder axle to rotate, realize elevator car position ground is detected in real time, after the unexpected power-off of elevator is restarted, car is gone to upstation or station, lower end, correcting switch or the action of lower correcting switch in triggering, thereby the car position data of recovery charging unit controller.When elevator is during in halted state, charging unit controller 113 drives flexible contact to stretch out, and is communicated with charging path, is communicated with steel rope 3 and low pressure constant-current source circuit, to chargeable storage charging in car power supply part 9.Flexible contact state shown in Fig. 1 is charge condition.When elevator is during in state in service, charging unit controller 113 drives flexible contact retraction, disconnects charging path, disconnects steel rope 3 and low pressure constant-current source circuit, stops chargeable storage charging in car power supply part 9.When elevator is during in halted state, if coder 211 detects car accidental movement, charging unit controller 113 is exported a signal, and this signal can be controlled electromagnetism wire holder or electromagnetism speed limit device, and that elevator is stopped is mobile.
As an example of the mounting means of Fig. 2 example, lift car charging unit of the present invention is described below, Fig. 2 is identical with the parts that first embodiment Fig. 1 uses, and no longer describes in detail at this.Different from the first embodiment, the mounting means that the flexible contact 14 of Fig. 1 second and the first flexible contact 18 adopt is mounted in power supply box 13 both sides, and Fig. 2 is mounted in 13 li of power supply boxs; The fixed pulley that Fig. 1 adopts can be that electrically nonconducting material can be also conductive material, and the fixed pulley that Fig. 2 adopts is necessary for conductive material.
As an example of the mounting means of Fig. 3 example, lift car charging unit of the present invention is described below, Fig. 3 is identical with the parts that first embodiment Fig. 1 uses, and no longer describes in detail at this.Different from the first embodiment, fixed pulley is arranged on same one side of power supply box, connects on first between fixed pulley 17 and coder with cross round head bolt 312.Mounting means shown in Fig. 3 can be with reference to Fig. 2, and the contact that will stretch is arranged in power supply box, and this is also a kind of embodiment, no longer describes in detail at this.
Charging unit controller of the present invention, as shown in Figure 4, its principle of work is: in the time that elevator is worked, car drives the axle of coder 211 to rotate, the information process level shifting circuit 112 that coder 211 transmits, then after charging unit controller 113 is processed, send into electric life controller 116.After the unexpected power-off of elevator is restarted, car is gone to upstation or station, lower end, correcting switch or the action of lower correcting switch in triggering, correcting switch information 118 is through level shifting circuit 117, send into charging unit controller 113, thereby recover the car position data of charging unit controller 113, then pass to electric life controller 116.In the time that elevator is in state in service, electric life controller 116 sends cut-offing instruction, and charging unit controller 113 is received after instruction through overdrive circuit 114, drives flexible contact retraction, disconnects steel rope and low pressure constant-current source circuit, disconnects charge circuit.In the time that elevator is in halted state, electric life controller 116 sends charging instruction, charging unit controller 113 drives flexible contact to stretch out, and is communicated with steel rope and low pressure constant current source (being positioned at power supply box 17) circuit, starts chargeable storage charging in car power supply part 9.When car is in halted state, charging unit controller 113 receives the information that coder 211 transmits, and can export a signal by control relay 115, and this signal can control electromagnetism wire holder or electromagnetism speed limit device makes elevator stop moving.
Content described in this specification sheets embodiment is only enumerating of way of realization to inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention is also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
