Description
Technical field
The present invention relates to elevators field, particularly a kind of fender guard compensated for overhauling elevator door lock.
Background technology
The electric protection of door lock of elevator is mainly used in the generation of the shearing accident preventing a district, at present, and general employing two kinds of methods.First method is to provide gate interlock defencive function, is made a series loop by all door lock contacts, and when wherein any one contact is obstructed, whole gate interlock loop is just obstructed, and now elevator can not mule carriage.But gate interlock wants proper function can must have a prerequisite, and namely improper short circuit can not occur any part of gate interlock.Gate interlock once there is short circuit, such as, completing after maintenance lift completes and acts hurriedly in a messy situation not by the dismounting of short circuit door lock electric wire, even if car can be elevated when opening the door in the same old way, causing elevator accident to occur.For this reason, country just makes stipulations and forbids.
Because elevator causes maintenance difficult when keeping in repair because door lock is obstructed, making troubles to elevator reparing maintenance, reducing the efficiency of maintenance.Therefore be necessary that designing a kind of accident that both can prevent door lock short circuit from causing occurs, and can facilitate again elevator reparing work new departure easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of overhauling elevator door lock be simple and easy to and compensating fender guard.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of overhauling elevator door lock compensates fender guard, comprise the maintenance circuit being disposed with maintenance control loop and maintenance relay, described maintenance circuit is by power supply entrance point and power supply output point external source, the cross-over connection equalizer circuit in parallel with overhauling control loop is provided with between described power supply entrance point and maintenance relay, this cross-over connection equalizer circuit is provided with electronic control system, wherein said power supply entrance point and maintenance circuit, single pole double throw switch is provided with between cross-over connection equalizer circuit, door lock contact circuit is also connected with between described power supply entrance point and electronic control system, this door lock contact circuit is provided with door lock of elevator contact, described cross-over connection equalizer circuit is provided with compensation reset button, the mouth of this compensation reset button is connected to the position between door lock of elevator contact and electronic control system.
The invention has the beneficial effects as follows: this fender guard plays a part convenient and raises the efficiency in maintenance work; compensate fender guard by rational structure of modification; only need to make safe and efficient trouble-shooting in elevator reparing by single pole double throw switch and being connected in series of reset button of compensation; avoid because the accident that when maloperation causes opening the door, car is elevated in the same old way; the easy installation and maintenance of total, is conducive to applying of technology.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is electrical block diagram of the present invention;
Fig. 2 is use schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1; a kind of overhauling elevator door lock compensates fender guard; comprise the maintenance circuit MK being disposed with maintenance control loop T and maintenance relay K; described maintenance circuit MK is by power supply entrance point DCV24 and power supply output point DCV0 external source; wherein overhauling control loop T is the circuit module run when keeping in repair for controlling elevator, and overhauls relay K and normally run and output variable during service mode for the treatment of elevator.The cross-over connection equalizer circuit MF in parallel with overhauling control loop T is provided with between described power supply entrance point DCV24 and maintenance relay K, this cross-over connection equalizer circuit MF is provided with electronic control system KMJ, and wherein electronic control system KMJ is used for the electronic signal of maintenance control loop T input to perform an analysis to compare.Described power supply entrance point DCV24 and be provided with single pole double throw switch SPDT between maintenance circuit MK, cross-over connection equalizer circuit MF, for switching between maintenance circuit MK and cross-over connection equalizer circuit MF.Door lock contact circuit MSB is also connected with between described power supply entrance point DCV24 and electronic control system KMJ, this door lock contact circuit MSB is provided with door lock of elevator contact SB, door lock of elevator contact SB, for ensureing that elevator could run at closure state at door lock, namely can not open at the elevator door of maintenance period.Described cross-over connection equalizer circuit MF is provided with and compensates reset button G41, and the mouth of this compensation reset button G41 is connected to the position between door lock of elevator contact SB and electronic control system KMJ.
With reference to Fig. 1, Fig. 2, single pole double throw switch SPDT can adopt can reset button, when cross-over connection equalizer circuit MF connected by the button pressing single pole double throw switch SPDT, also cut off maintenance circuit MK simultaneously, device is in inspecting state in real time, the work of maintenance relay K, and the effect compensating loop of the door lock is played in the normally closed contact conducting of maintenance relay K, then press when compensating reset button G41 and just can compensate whole door lock circuit, just can follow and remove select button AD according to needs by car direction traveling.When compensation reset button G41 is late for, the button automatic spring compensating reset button G41 resets, and no longer compensates door lock.When service work completes, then operation sheet double-pole double throw switch SPDT resets, and connects maintenance circuit MK, cuts off cross-over connection equalizer circuit MF, thus play safety and protective effect.
According to above-mentioned principle, the present invention can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the present invention is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.
Through facts have proved; this fender guard plays a part convenient and raises the efficiency in maintenance work; compensate fender guard by rational structure of modification; only need to make safe and efficient trouble-shooting in elevator reparing by single pole double throw switch SPDT and being connected in series of compensation reset button G41; the easy installation and maintenance of total, is conducive to applying of technology.
