Description
Technical field
The utility model belongs to the state inspection field of elevator traction machine or elevator, is specifically related to a kind of device that drg opening/closing action in elevator traction machine is detected, and is the improvement to existing brake status detecting device.
Background technology
Drg on elevator traction machine or elevator is all provided with micro-switch, action for detection of drg opening/closing, be specially: before elevator car arrives designated floor, the induction installation on elevator can be given the signal of control system slowing-down brake, and drg implements closing movement; Before lift car leaves designated floor, apparatus for controlling elevator sends and starts the instruction discharging, and drg implements opening action.When drg opens or closes action, micro-switch is braked the associated components shake-up on device and makes corresponding action, the normal closure of making war, normally closed point disconnects, give the signal of the normal work of drg of control system, otherwise control system has corresponding program and starts, such as: warning, emergency braking apparatus startup etc.Concrete structure as shown in Figure 1, 2, it is an embodiment of the brake status detecting device of elevator traction machine in prior art, it comprises Moving plate 1, quiet dish 3, push rod 2 and micro-switch 4, coil pack 31 and retarding spring 32 are installed in quiet dish 3, shown in figure is that retarding spring 32 in drg quiet dish 3 of when braking promotes Moving plates 1 friction disc 6 is clamped between Moving plate 1 and mounting seat of brake 7, now between quiet dish 3 and Moving plate 1, have gap A, this gap A is the actuating length of drg opening/closing.Described micro-switch 4 is arranged on micro-switch mount pad 5 by screw, and described micro-switch mount pad 5 is arranged in the quiet dish mounting groove 33 of quiet dish 3 by screw; Described push rod 2 spirals are arranged on Moving plate 1, and its one end is rear corresponding with the contact 41 of described micro-switch 4 through Moving plate 1.During coil electricity in coil pack 31, between the air gap between quiet dish 3, Moving plate 1 and quiet dish 3 and Moving plate 1, be formed with magnetic loop, produce electromagnetic force, the elastic force that this electromagnetic force overcomes retarding spring 32 makes quiet dish 3 adhesive Moving plates 1, now be arranged on the contact 41 that push rod on Moving plate 12 touches micro-switchs 4, the action of described contact 41 by the feedback of status of drg to control system.The deficiency that this structure exists is: because the actuating length of drg opening/closing is too little and frequent, affected the regular event of micro-switch 4, there is maloperation phenomenon, be that micro-switch sends wrong signal to control system sometimes, make control system send wrong instruction and stop elevator, cause the people's event of closing.
For above-mentioned existing problems, in order to improve the reliability of micro-switch action, common way is to increase stroke amplifying mechanism between Moving plate 1 and micro-switch 4, by amplifying the actuating length A of Moving plate, guarantees that micro-switch is made accurately and reliably and moves.Through retrieval, find, Chinese utility model patent Granted publication CN2923626Y disclosed " a kind of mechanism for detection of brake status " for example, Chinese utility model patent Granted publication CN203021132U disclosed " a kind of testing agency of brake status ", also has European patent Granted publication EP1445784B1 disclosed " a kind of micro-switch that lever is installed ", these patents all disclose between Moving plate and micro-switch increases stroke amplifying mechanism, prevent the scheme of micro-switch generation maloperation, but whether no matter stroke amplifying mechanism be installed, utilize micro-switch all to have the following disadvantages as the detecting device of drg: first, micro-switch is contact travel switch, its appliance life is generally 50,000 times, and drg General Requirements on elevator traction machine can operate 2,000,000 times, so the micro-switch being installed on existing on elevator brake is shorter service life, secondly, the limit travel that micro-switch allows is very little, the 3rd, structural strength is inadequate, easily produces mechanical fatigue, the 4th, temperature influence, its Reliability of Microprocessor is poor.In view of above-mentioned existing problems, make existing micro-switch can not meet the requirement of elevator long-term safety operation.
For this reason, the applicant has done actively and actv. is explored, and has finally formed technical scheme described below.
