Abstract

The utility model discloses an elevator shaft safety device, characterized by comprising an air bag arranged on the bottom part of the elevator shaft, the air inlet of the air bag is connected with an air tank through an electromagnetic control valve, and dry ice is fulfilled in the air tank; the elevator shaft safety device further comprises a control center and an acceleration sensor, wherein the acceleration sensor is arranged on the elevator for detecting the operation acceleration of the elevator, and the control center is respectively connected with the acceleration sensor and the electromagnetic control valve. The elevator shaft safety device disclosed by the utility model has the advantages of detecting and controlling by electric signals to more effectively detect whether the elevator is at a descending state and guarantee the aeration control effectiveness of the air bag; besides, the dry ice tank is used for aerating to guarantee a short aeration duration of the air bag so as to greatly improve the safety of the elevator shaft, and the air bag can be used for effectively guaranteeing the life safety of the passengers in the elevator in case of accidental dropping of the elevator.

Description

A kind of elevator safety device
Technical field
The utility model relates to a kind of elevator safety device, especially relates to a kind of elevator safety device.
Background technology
Elevator is a kind of vertical lifting equipment that is used for building, in the high building of modern city, has all adopted the lift facility transportation of going up and down.During the elevator operation; Be to adopt steel rope to carry out vertical-lift, in order to guarantee safety, the steel rope and the pair that generally need to adopt a pair to be used to promote are used for subsequent use steel rope; When the steel rope that is used to promote broke down fracture, subsequent use steel rope can guarantee that elevator can not weigh down down.However, because fracture also possibly appear in subsequent use steel rope, and facility management moves reasons such as improper sometimes, and still can there be the risk of certain air crash in elevator.At home, also hear the report of relevant elevator fall accident often.
In order to improve the elevator driving safety, in the prior art, also there is the technology of a large amount of elevator car safeties.Such as; China's application number 200910016727.8 disclosed a kind of safety and shock-absorption air bag cushion of elevator; Its shape size, undersized identical with the elevator tank top plate is provided with blast pipe on the limit near the inside and extends outside the elevator, is provided with individual event valve, valve seat, check valve spring, spring backing pin in the blast pipe; It is horn-like that the ventilation inlet of blast pipe is back-off, this safety and shock-absorption air bag cushion of elevator elevator for some reason the acceleration/accel of free fall out of control be equal to and greater than 9.8m/s 2The time, the air cushion that is located at passenger underfooting on the elevator base plate plays the bumper and absorbing shock effect with automatic topping-up gas when elevator contacts to earth, thereby reduces passenger's damage.But the air intake valve of this physical construction; Draw reasons such as spring is stuck, inefficacy easily; Cause air intake untimely, and descending speed is very fast during used during elevator falling, usually in tens seconds even several seconds, promptly arrives the shaft bottom; So this existing safety and shock-absorption air bag cushion of elevator technology, being difficult to provides effective guarantee to passenger safety.
The utility model content
To the deficiency of above-mentioned prior art, the utility model technical matters to be solved is how to provide a kind of safety higher elevator safety device.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of elevator safety device, its characteristics are, comprise the safety air bag that is arranged at the elevator shaft bottom, and the admission port of safety air bag connects a gas tank through solenoid electric valve, is filled with dry ice in the said gas tank; Also comprise control center and acceleration pick-up, said acceleration pick-up is arranged on the elevator and is used to detect elevator operation acceleration/accel, and said control center links to each other with solenoid electric valve with acceleration pick-up respectively.
In the present technique scheme; Safety air bag is arranged on the elevator bottom hole location; Like this with air bag is arranged on elevator bottom and compares, its safety air bag can be provided with more greatly to improve safety, also is convenient to for air bag gas filled device is set simultaneously; Can also alleviate elevator weight in addition, avoid being provided with of safety air bag that elevator self is impacted.Simultaneously, in the present technique scheme, adopt the dry ice jar to come air bag is put on the air, had inflation advantage efficiently rapidly, shortened inflationtime, further improved safety control.While the utility model adopts acceleration pick-up that elevator is moved acceleration/accel and detects, and makes to detect to judge that more sensitivity is 9.8m/s with effective when detecting elevator operation acceleration/accel 2The time (certainly, accekeration is judged in concrete detection, can according to using local particular case specifically be provided with); Can judge that elevator is in the nature falling state, after sensor was delivered to control center with detection signal, control center can send the instruction control solenoid electric valve and open; Dry ice in the gas tank enters into the interior CO2 that forms of air bag rapidly and puts on the air; Air bag can expand rapidly, treats can form resilient protection after elevator falls, and avoids causing fatal crass's result.Wherein, the solenoid electric valve of employing and acceleration pick-up are ripe prior art, and directly buying the existing product assembling can obtain, so its concrete structure is not at this detailed description.Simultaneously, control center can be the control center that directly adopts elevator self to wear, and also can be to adopt an independent PLC, all should be regarded as falling into the utility model protection domain.
In sum, the utility model adopts electrical signal detection and control, can detect elevator more effectively and whether be in the decline state; Also can guarantee the validity of airbag aeration control; Adopt the inflation of dry ice jar, can guarantee that the airbag aeration time short, so improved the elevator safety greatly; When accident bob well appears in elevator self, can ensure passenger's in the elevator life security effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of elevator safety device comprises the safety air bag 2 that is arranged at elevator 1 shaft bottom, and the admission port of safety air bag 2 connects a gas tank 4 through solenoid electric valve 3, is filled with dry ice in the said gas tank 4; Also comprise control center 5 and acceleration pick-up 6, said acceleration pick-up 6 is arranged on the elevator 7 and is used to detect elevator 7 operation acceleration/accels, and said control center 5 links to each other with solenoid electric valve 3 with acceleration pick-up 6 respectively.During practical implementation, can adopt wireless signal to connect between said control center 5 and the acceleration pick-up 6, also can adopt wireless signal to connect between said control center 5 and the solenoid electric valve 3.

Claims (1)

1. an elevator safety device is characterized in that, comprises the safety air bag that is arranged at the elevator shaft bottom, and the admission port of safety air bag connects a gas tank through solenoid electric valve, is filled with dry ice in the said gas tank; Also comprise control center and acceleration pick-up, said acceleration pick-up is arranged on the elevator and is used to detect elevator operation acceleration/accel, and said control center links to each other with solenoid electric valve with acceleration pick-up respectively.
