Abstract
The utility model provides a kind of Elevator weight sensor close to early warning system, including elevator；Car is installed and to pouring weight in the elevator, counterweight area is provided with the elevator, the upper and lower part in the counterweight area is mounted on being provided with magnetic bistable switch between induced magnet, induced magnet, and the magnetic bistable switch is also connected with alarm.The utility model passes through the data such as cage top overhauling signal of sampling, elevator run signal, counterweight access areas signal, judge the relative position of car and counterweight, meet after the operation condition of the device, device sounds the alarm sound, maintenance personnel are reminded to notice that counterweight will be approached and crossed with car, it is to avoid to occur contingency.
Description
Technical field
The utility model is related to a kind of Elevator weight sensor close to early warning system.
Background technology
Among the ordinary maintenance maintenance of elevator, it is than relatively hazardous that maintenance personnel carry out slow train operation in car top.
Especially in counterweight access areas, maintenance personnel easily collide with counterweight when checking hoistway equipment, there is hair when serious
The possibility of raw shearing accident, situation about causing casualties with device damage.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of Elevator weight sensor close to early warning system.
The utility model is achieved by the following technical programs.
A kind of Elevator weight sensor that the utility model is provided is close to early warning system, including elevator；Installed in the elevator
There is car and to pouring weight, counterweight area is provided with the elevator, the upper and lower part in the counterweight area is mounted on sensing magnetic
Magnetic bistable switch is installed, the magnetic bistable switch is also connected with alarm between iron, induced magnet.
Inspection switch and run switch, inspection switch and run switch series connection are additionally provided with the elevator.
The inspection switch and run switch are normally opened contact.
The alarm is connected with inspection switch and run switch.
The beneficial effects of the utility model are：By cage top overhauling signal of sampling, elevator run signal, counterweight close to area
The data such as domain signal, judge the relative position of car and counterweight, meet after the operation condition of the device, device sounds the alarm
Sound, reminds maintenance personnel to notice that counterweight will be approached and crossed with car, it is to avoid to occur contingency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is control principle drawing of the present utility model；
In figure：1- elevators, 2- cars, 3- is to pouring weight, 4- counterweights area.
Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
A kind of Elevator weight sensor is close to early warning system, including elevator 1；Car 2 is installed and to pouring weight in the elevator 1
3, counterweight area 4 is provided with the elevator 1, and the upper and lower part in the counterweight area 4 is mounted on induced magnet, induced magnet
Between magnetic bistable switch is installed, magnetic bistable switch is also connected with alarm.
Inspection switch and run switch, inspection switch and run switch series connection are additionally provided with the elevator 1.
The inspection switch and run switch are normally opened contact.
The alarm is connected with inspection switch and run switch.
(1) to ensure elevator device not misoperation in normal operation, device needs to gather cage top overhauling signal, judges electricity
Whether ladder is in cage top overhauling state.When elevator is normally run, device does not work.Can cage top overhauling switch on connect one it is normally opened
Function is realized in contact, and contact disconnects when elevator is normally run, during cage top overhauling switch motion, the closing of contact.
(2) to avoid when elevator is parked in counterweight close to area and equilibrium area operation by maintenance personnel device work always
Alarm is sent, the device need to gather the run signal of elevator, judge the running status of elevator, when elevator is not run, device
It is failure to actuate.The equipment such as button can be run by operation contactor, band-type brake contactor, car top and one normally opened contact is provided, elevator stops
Contact disconnects during operation, closing of contact when elevator is run.
(3) in order to allow the device to be sounded the alarm sound in whole counterweight access areas, the device also needs to judge to reclosing
The position of near field.Magnetic bistable can be used to switch, one sensing is respectively installed on the top of whole access areas and bottom
Magnet so that magnetic bistable switch is connected in whole region, is left and is switched off behind region.
(4) audio warning equipment (can record the signal languages such as " noticing that counterweight is approached ", " taking care " using speech ciphering equipment
Sound) or buzzer, sound the alarm sound after device action.
The utility model sends warning buzzing when the personnel of maintenance are close with counterweight in car top progress slow train operation
Sound or phonetic warning, remind maintenance personnel to notice that counterweight is approached, it is to avoid counterweight shears the generation of accident, it is ensured that personnel's person
Safety.
