Abstract
The present invention relates to a kind of door-opened elevator car slipping protection device, belong to elevator safety field.It includes car and is used for the folder rail safety tongs for clamping car on car, well enclosure and the flat bed inductor on well enclosure, the folder rail safety tongs is connected with drive system, the drive system is connected with control circuit, the control circuit is connected with security control plate, and the control security control plate is fixedly installed power supply.Usefulness of the present invention is：It can fundamentally prevent due to elevator safety accident caused by car slipping, be greatly enhanced lift running safety level.
Description
Technical field：
The present invention relates to a kind of door-opened elevator car slipping protection device, belong to elevator safety field.
Background technology：
Elevator car slipping is a kind of elevator faults frequently encountered in elevator routine use, is brake the main reason for car slipping
Power is insufficient and exists caused by the additional power opened a sluice gate.Due to elevator car slipping, it is easy to cause shearing to injure to passenger, and this
It is all fatal that a little injuries are often a lot, and the economic loss thus brought is also a considerable number.Brake troubles
Caused elevator car slipping phenomenon is it could also be possible that because of irrational elevator arrangement, such as two terraced eight families, in these local works
Elevator its number of run can reach 1 year 1000000 times, also imply that brake will be braked 1,000,000 times for 1 year, so hold very much
Misfunctioning of brake is easily caused so as to cause the generation of car slipping accident, therefore, the safe operation for elevator is reliable except needing
Brake and rational elevator are used outside configuration, when car slipping phenomenon occurs for elevator, how timely and effectively to solve this
Individual problem is also highly important.
The content of the invention：
In order to solve the above-mentioned technical problem, a kind of door-opened elevator car slipping protection device provided by the invention, including car and installation
It is used for the folder rail safety tongs for clamping car, well enclosure and the flat bed inductor on well enclosure, the folder on car
Rail safety tongs is connected with drive system, and the drive system is connected with control circuit, and the control circuit is connected with security control
Plate, the control security control plate are fixedly installed power supply.
Further, the dynamic system of the driving is provided with electromagnetic switch, and the corresponding control circuit is provided with induction coil, can
To start drive system in time when elevator slips ladder, the reaction speed of whole device is improved.
Further, the control circuit is arranged on car top, and electromagnetic switch correspondence position is provided with magnetic isolation plate, kept away
The error starting of folder rail safety tongs is exempted from.
Further, the power supply is the independent current source not being connected with extraneous power network, and in external power failure, safety tongs is still
Energy normal use, improve the stability and reliability of protection device.
When car slipping situation occurs for elevator, now magnetic isolation plate will depart from flat bed inductor, once magnetic isolation plate departs from, be connected on
Coil in the same circuit will obtain electric, so that pull bar lifts safety tongs, act safety tongs, car braking is stopped at and led
On rail, prevent elevator from continuing car slipping.
Compared with prior art, usefulness of the present invention is：Can fundamentally it prevent due to elevator caused by car slipping
Security incident, it is greatly enhanced lift running safety level.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is a kind of schematic diagram of embodiment of door-opened elevator car slipping protection device.
In figure：1st, car；2nd, flat bed inductor；3rd, well enclosure；4th, rail safety tongs is pressed from both sides；5th, drive system；6th, control circuit；
7th, security control plate；8th, power supply；9th, electromagnetic switch；10th, induction coil；11st, magnetic isolation plate
Embodiment：
As shown in figure 1, a kind of door-opened elevator car slipping protection device provided by the invention, including car 1 and used on car 1
In the folder rail safety tongs 4 for clamping car, well enclosure 3 is arranged on the flat bed inductor 2 on well enclosure 3, and the folder rail safety tongs 4 connects
Drive system 5 is connected to, the drive system 5 is connected with control circuit 6, and the control circuit 6 is connected with security control plate 7, institute
State control security control plate 7 and be fixedly installed power supply 8.The dynamic system 5 of driving is provided with electromagnetic switch 9, the corresponding control electricity
Road 6 is provided with induction coil 10, can start drive system in time when elevator slips ladder, improve the reaction speed of whole device.
The control circuit 6 is arranged on the top of car 1, and the correspondence position of electromagnetic switch 9 is provided with magnetic isolation plate 11, avoids folder rail safety
The error starting of pincers, the power supply 8 are the independent current source not being connected with extraneous power network, and in external power failure, safety tongs still can be just
Often use, improve the stability and reliability of protection device.
When car slipping situation occurs for elevator, now magnetic isolation plate 2 will depart from flat bed inductor 2, once magnetic isolation plate 11 departs from, string
The induction coil 10 being associated in control circuit 6 will obtain it is electric so that pull bar lifting lock rail safety tongs 4, makes lock rail safety tongs 4
Action, the braking of car 1 are stopped on guide rail, prevent elevator from continuing car slipping.Flat bed inductor 2 can send information to safety afterwards
Control panel 7, security control plate 7 will control drive system 5 to power off, and further improve the stability of the device.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made any formal
Limitation, every any simple modification, equivalent change and modification for being made to above example of technical spirit according to the present invention,
In the range of still falling within technical solution of the present invention.
