Abstract
The utility model discloses an elevator lift car safety device. The elevator lift car safety device comprises a releveling position sensor (1) which is connected with a traction machine (6) through a microcontroller (2), a shunt release (3) and a circuit interrupter (4) in sequence. According to the elevator lift car safety device, when unexpected movements occur to an elevator lift car, the shunt release is activated, and the circuit interrupter on the side of the traction machine is disconnected, so that shearing accidents of the elevator caused by the unexpected movements of the elevator lift car are avoided. According to the elevator lift car safety device, when the unexpected movements occur to the elevator lift car, a sound-light alarming device is controlled through a microcontroller so as to issue the sound-light alarm and warn a passenger that the elevator breaks down, so that the elevator is enabled to be safe and reliable. The elevator lift car safety device has the advantages of being easy to carry out, low in cost, economical and practical.
Description
Technical field
The utility model relates to a kind of lift car safety device, belongs to elevator industry technical field.
Background technology
Along with the development of national economy society, elevator has obtained using widely in various buildings.But the elevator safety problem is taken elevator to people and is impacted.
Car is under the door opening state, because the single component failure of the drive system that elevator main or car safety operation rely on is caused unexpected mobile, makes car leave flat bed zone again, very easily causes and shears injury, and elevator need be protected immediately.Therefore design a kind of unexpected mobile lift car safety device of lift car that can detect is necessary very much.
The utility model content
The purpose of this utility model is, a kind of lift car safety device is provided.The utlity model has and to detect the unexpected mobile advantage of car, avoided because of the unexpected mobile shearing accident that takes place of lift car, and the utlity model has advantage easy to implement, with low cost.
The technical solution of the utility model: a kind of lift car safety device, comprise level position sensor again, the level position sensor is connected with towing machine through microcontroller, shunt release, circuit breaker successively again.
In the aforesaid lift car safety device, described microcontroller also is connected with the acoustic-optic alarm that is installed in cab interior.
Compared with prior art, the utility model meets accident when mobile at lift car, activates shunt release, disconnects the circuit breaker of traction pusher side, has avoided elevator because of the unexpected mobile shearing accident that takes place of lift car; The utility model meets accident when mobile at lift car, by the microprocessor control acoustic-optic alarm, sends sound and light alarm, and the prompt passengers elevator breaks down, and makes safer, reliable; And the utility model is easy to implement, and is with low cost, has economical and practical characteristics.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Being labeled as in the accompanying drawing: 1-is the level position sensor again, 2-microcontroller, 3-shunt release, 4-circuit breaker, 5-acoustic-optic alarm, 6-towing machine.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of lift car safety device as shown in Figure 1, comprises level position sensor 1 again, and level position sensor 1 is connected with towing machine 6 through microcontroller 2, shunt release 3, circuit breaker 4 successively again.Described microcontroller 2 also is connected with the acoustic-optic alarm 5 that is installed in cab interior.
Principle of work of the present utility model: microcontroller 2 bases are the output signal of level position sensor 1 again, judge lift car whether meet accident mobile (unexpected mobile refers to that lift car has left flat bed zone again), if, then by activating shunt release 3 cut-off breakers 4, towing machine 6 can not be started, elevator can not move, and controls acoustic-optic alarm 5 simultaneously and sends sound and light alarm, the prompt passengers Lift out of order.
Claims (2)
1. lift car safety device, it is characterized in that: comprise level position sensor (1), level position sensor (1) is connected with towing machine (6) through microcontroller (2), shunt release (3), circuit breaker (4) successively more again.
2. lift car safety device according to claim 1, it is characterized in that: described microcontroller (2) also is connected with the acoustic-optic alarm that is installed in cab interior (5).
