Abstract
The utility model discloses a protecting device against mistaken opening of a door of an elevator out of control. The protecting device comprises an elevator cage (1), the elevator door (2), a dragging system (3) and a monitoring duty room (4), wherein a wall, opposite to a hoist-way, of the elevator door (2) is provided with a human-body heat-releasing infrared detecting system (5), an alarm apparatus (6) is installed on a wall on the upper portion of the elevator door, the human-body heat-releasing infrared detecting system (5) comprises a human-body heat-releasing infrared sensor and a signal processing system, the inner side of the elevator door or the outer side of the elevator door is provided with a safe fence (7), the human-body heat-releasing infrared sensor and the signal processing system are connected, the signal processing system is respectively connected with the alarm apparatus (6), the monitoring duty room (4) and a servo driving system, the servo driving system is connected with a motor, and the motor is connected with the safe fence (7). When the elevator door is opened and the elevator cage does not come, the protecting device against mistaken opening of the door of the elevator out of control can give an alarm and starts the safe fence to prevent passengers from entering an elevator and falling into the bottom of the hoist-way and elevator accidents can be effectively reduced.
Description
Technical field
The utility model relates to a kind of elevator fender guard that opens by mistake out of control.
Background technology
According to statistics, China is having more than 34.6 ten thousand with elevator, and is annual also with about 50,000～60,000 speed increment.Existing more than the 100 year history of elevator service China, and Chinese after the quick growth with elevator quantity occurs in reform and opening-up, present Chinese elevator technology level is synchronous with the world, elevator is prevalent in all kinds of high buildings already.The elevator of extensively knowing roughly is divided into two classes: a class is the handrail-type elevator that the megastore installs and uses; Another kind of is the lifting mode elevator.The elevator of installing and using in early days, period of service is decades-long, though continue operation through maintenance, but elevator in use still unsatisfactory fault can occur, and the elevator casualty accident happens occasionally, it is reported demonstration, cage lifter occur repeatedly that elevator door leaves and lift car not extremely, cause the passenger because the careless and inadvertent elevator shaft bottom of falling behind the elevator that enters causes injured even dead accident, bring know clearly tremendous loss and the pain of injury to people.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; provide a kind of can elevator door open and elevator not to the time; prevent the passenger because negligence enters elevator by giving the alarm and opening catch fence; the elevator fender guard that opens by mistake out of control of elevator accident and personal casualty can be effectively reduced in the shaft bottom of falling.
The purpose of this utility model is achieved through the following technical solutions: it comprises lift car, elevator door, traction system and monitoring watch house, the hoistway of elevator door is provided with people's body heat to sidewalls and releases infrared detection system, on the wall of elevator door top annunciator is installed, described people's body heat is released infrared detection system and is comprised the pyroelectric infrared sensor of human body and signal handling equipment, elevator door inboard or the outside are equipped with catch fence, the pyroelectric infrared sensor of described human body links to each other with signal handling equipment, signal handling equipment respectively with annunciator, the monitoring watch house is connected with servo drive system, servo drive system links to each other with motor, and motor is connected with catch fence.
Annunciator also is connected with the monitoring watch house.
Advantage of the present utility model is:
(1) adopt warning and startup catch fence duplicate protection, both can give the alarm, remind the passenger not enter elevator, can the substantial passenger of preventing enter in the elevator door of lift car no show because of negligence again, the elevator shaft bottom of falling causes injures and deaths.
(2) signal handling equipment links to each other with the monitoring watch house, can in time notify attendant's elevator operating troubles, makes things convenient for the attendant in time to close Zong Zha, guarantees passenger's safety, and in time elevator is overhauled that trouble-shooting is reduced the loss.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 releases the signal handling equipment diagram of circuit of infrared detection system for people's body heat of the present utility model;
Among the figure, the 1-lift car, the 2-elevator door, the 3-traction system, 4-monitors watch house, and 5-people's body heat is released infrared detection system, 6-annunciator, 7-catch fence.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing, but the content that the utility model is protected is not limited to the following stated.
As shown in Figure 1; an elevator fender guard that opens by mistake out of control; it comprises lift car 1; elevator door 2; traction system 3 and monitoring watch house 4; the hoistway of elevator door 2 is provided with people's body heat to sidewalls and releases infrared detection system 5; on the wall of elevator door top annunciator 6 is installed; described people's body heat is released infrared detection system 5 and is comprised the pyroelectric infrared sensor of human body and signal handling equipment; elevator door inboard or the outside are equipped with catch fence 7; the pyroelectric infrared sensor of described human body links to each other with signal handling equipment; signal handling equipment respectively with annunciator 6; monitoring watch house 4 is connected with servo drive system; servo drive system links to each other with motor, and motor is connected with catch fence 7.
Annunciator 6 also is connected with monitoring watch house 4, when elevator accident occurs and keeps in repair, passes in and out elevator for convenience of the maintainer, elevator door 2 is opened, catch fence 7 is in halted state, and monitoring watch house 4 sends alerting signal and is sent to annunciator 6, and the passenger is given the alarm.
Principle of work of the present utility model is: motor drives lift car 1 by traction system 3 and moves up and down, and during the elevator normal operation, the pyroelectric infrared sensor of human body detects releases infrared signal less than people's body heat, and annunciator 6 and catch fence 7 all are in halted state.Press certain layer elevator button as the passenger, lift car 1 is because fault or out of control not when preposition stops, but elevator door 2 is opened automatically, the pyroelectric infrared sensor fast detecting of human body that is installed in the hoistway opposite of elevator door 2 is released infrared signal to people's body heat, and be converted into carry out multistage amplification behind the electric signal and handle after, divide three the tunnel road to transmit this signal: the one tunnel transmits annunciator 6, gives the alarm, and prompt passengers does not enter elevator; The second the tunnel is sent to servo drive system, and servo drive system control motor action drives catch fence 7 quick closedown catch fence, stops that whereby this floor passenger enters elevator; The Third Road signal is sent to Control Room 4 on duty, points out the elevator operation to break down to the attendant, please the staff in time overhaul, and trouble-shooting is reduced the loss.
As shown in Figure 2, the signal processing that people's body heat of the present utility model is released infrared signal is: after people's body heat is released infrared signal and passed through the multistage amplification of pre-amplification circuit, gain amplifying circuit and variable amplifying circuit successively, be sent to triggering system, after triggering system receives signal, by the pump line system, electric signal is sent to annunciator, servo drive system and monitoring watch house respectively.
