Abstract
The invention discloses a safety alarm reminding device before operation in a pit and a car top, which comprises a human body induction module, a voice alarm module and an emergency stop switch, wherein the human body induction module is arranged on the wall of a pit inlet well, and the human body induction module, the voice alarm module and the emergency stop switch are electrically connected; when a maintenance worker opens a door of a bottom hall, the human body sensing module senses a person, the voice alarm module is triggered to automatically send out an alarm voice prompt, and the alarm voice is played in a circulating mode all the time before entering a pit if the emergency stop is not pressed; the entrance emergency stop switch is reset when the pit is withdrawn, and after the hall door is closed, the human body sensor cannot sense the existence of people due to the isolation of the hall door leaf, and cannot trigger an alarm signal, so that the alarm cannot be given out.
Description
Technical Field
The invention relates to the technical field of elevator safety protection, in particular to a safety alarm reminding device before entering a pit and a car top for operation.
Background
With the increasing popularization of the elevator, the related employment personnel in the elevator industry are increased, but the comprehensive quality of field operation personnel is uneven, and particularly, the phenomena of big attention and irregular operation of tigers during operation generally exist in the safety aspect. For example, when the elevator enters a pit or a car roof, the elevator can enter the elevator directly without turning on an emergency stop switch after the hall door is opened, so that the elevator can be started suddenly after the hall door is closed, great personal safety hazards are generated for operators, and finally, casualties are caused. This is partly due to bad habits (or laziness) that are not made with a long-term awareness of safety, and partly due to forgetting to make an emergency stop in dealing with the problem. At present, the safety education for elevator operators is basically a field declaration of platform organizations in companies or other departments, the elevator operators are required to go deep into the centers of every person and are difficult to guarantee self-reminding all the time, and no device for automatically reminding the elevator operators on the field is provided, so that the operators are warned to operate normally before entering an operation area every time, and accidents are avoided. Therefore, it is necessary to warn elevator operators in real time on site.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the existing defects and provide a safety alarm reminding device before entering a pit and a car roof for operation, the device is more flexible and simpler in material loading, a cutting blade is pressed into a cutting groove by pressing a pressing block to complete the cutting of paper and plastic, and a cutting mechanism returns to the initial position under the action of a return spring after cutting, so that the use is convenient; because the multistage layer and the simultaneity that spacing disc, spacing fluting and cut-off tank were moulded paper are spacing, off tracking when preventing paper from moulding the extraction makes the paper that cuts off mould neatly more simultaneously, tailors more high-efficient more smooth, can effectively solve the problem among the background art.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a get into safety warning reminding device before pit and sedan-chair top operation, includes and comprises human response module, audio alert module and scram switch triplex, human response module installs on pit entry well wall, electric connection between human response module, audio alert module and the scram switch to get into the pit operation as an example: after a maintenance worker opens a bottom hall door, a human body sensing module arranged on the wall of a pit entrance shaft senses a person and continuously outputs a signal to trigger a voice alarm module to automatically send out an alarm voice prompt, the voice alarm is stopped after an entrance scram switch is pressed before entering a pit, and the alarm voice is continuously and circularly played if the scram is not pressed; when the maintenance personnel withdraw out of the pit after the maintenance personnel are finished, the entrance emergency stop switch is reset, and when the hall door is closed, the human body sensor cannot sense the existence of people due to the isolation of the hall door leaf, and cannot trigger an alarm signal, so that the condition of false alarm cannot occur. The induction angle range of the human body inductor is as follows: 0-120 DEG, induction distance: 2-5 m adjustable. The power supply utilizes pit talkback DC12V to supply power, and because the emergency 12V power supply of talkback of the power supply of the talkback system automatically supplies power when the power supply has a power failure, the alarm device can be reliably and effectively used no matter the normal power supply has power or enters the pit under the condition of power failure.
Furthermore, the voice content of the voice alarm module can be input in a user-defined mode.
Further, the induction angle range of the human body inductor is as follows: 0 ~ 120, induction distance is: 2-5 m.
Compared with the prior art, the invention has the beneficial effects that: taking pit entry as an example: after a maintenance worker opens a bottom hall door, a human body sensing module arranged on the wall of a pit entrance shaft senses a person and continuously outputs a signal to trigger a voice alarm module to automatically send out an alarm voice prompt, the voice alarm is stopped after an entrance scram switch is pressed before entering a pit, and the alarm voice is continuously and circularly played if the scram is not pressed; when the maintenance personnel withdraw out of the pit after the maintenance personnel are finished, the entrance emergency stop switch is reset, and when the hall door is closed, the human body sensor cannot sense the existence of people due to the isolation of the hall door leaf, and cannot trigger an alarm signal, so that the condition of false alarm cannot occur. The induction angle range of the human body inductor is as follows: 0-120 DEG, induction distance: 2-5 m adjustable. The power supply utilizes pit talkback DC12V to supply power, and because the emergency 12V power supply of talkback of the power supply of the talkback system automatically supplies power when the power supply has a power failure, the alarm device can be reliably and effectively used no matter the normal power supply has power or enters the pit under the condition of power failure.
