Description
Technical field
The utility model relates to elevator field, particularly a kind of fender guard for the compensation of overhauling elevator door lock.
Background technology
The electric protection of door lock of elevator is mainly used in preventing the generation of the shearing accident in a district, at present, generally adopts two kinds of methods.First method is to provide gate interlock defencive function, be about to all door lock contacts and make a series loop, 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 must have a prerequisite, can not there is improper short circuit in any part of gate interlock.Once there is short circuit in gate interlock, for example, after completing maintenance lift and completing, act hurriedly in a messy situation and short circuit door lock electric wire is not removed, even car in the same old way can lifting in the situation that opening the door, cause 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, to elevator reparing, maintenance makes troubles, and reduces the efficiency of maintenance.Therefore be necessary to design a kind of accident that both can prevent that door lock short circuit from causing and occur, can facilitate again elevator reparing work new departure easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of overhauling elevator door lock compensation fender guard that is simple and easy to use.
The utility model solves the technical scheme that its technical matters adopts:
A kind of overhauling elevator door lock compensation fender guard, comprise the maintenance circuit that is disposed with maintenance control loop and maintenance relay, described maintenance circuit is by power supply entrance point and power supply output point external source, between described power supply entrance point and maintenance relay, be provided with the cross-over connection equalizer circuit in parallel with overhauling control loop, this cross-over connection equalizer circuit is provided with electronic control system, wherein said power supply entrance point and maintenance circuit, between cross-over connection equalizer circuit, be provided with single pole double throw switch, between described power supply entrance point and electronic control system, be also connected with door lock contact circuit, 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 beneficial effects of the utility model are: this fender guard plays a part convenient and raises the efficiency in maintenance work; compensation fender guard is 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 car accident of lifting in the same old way in the maloperation situation that causes opening the door; the easy installation and maintenance of total, is conducive to applying of technology.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is electrical block diagram of the present utility model;
Fig. 2 is use schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1; a kind of overhauling elevator door lock compensation fender guard; comprise the maintenance circuit MK that is 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 overhaul control loop T and be for controlling the circuit module of elevator operation when the maintenance, and the output variable of maintenance relay K during for the treatment of the normal operation of elevator and service mode.Between described power supply entrance point DCV24 and maintenance relay K, be provided with the cross-over connection equalizer circuit MF in parallel with overhauling control loop T, this cross-over connection equalizer circuit MF is provided with electronic control system KMJ, and wherein electronic control system KMJ is for comparison that the electronic signal of maintenance control loop T input is performed an analysis.Between described power supply entrance point DCV24 and maintenance circuit MK, cross-over connection equalizer circuit MF, be provided with single pole double throw switch SPDT, for switching between maintenance circuit MK and cross-over connection equalizer circuit MF.Between described power supply entrance point DCV24 and electronic control system KMJ, be also connected with door lock contact circuit MSB, this door lock contact circuit MSB is provided with door lock of elevator contact SB, door lock of elevator contact SB is used for guaranteeing that elevator could move at closure state at door lock, at the elevator door of maintenance period, can not open.Described cross-over connection equalizer circuit MF is provided with compensation 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 pressing the button connection cross-over connection equalizer circuit MF of single pole double throw switch SPDT, also cut off maintenance circuit MK simultaneously, device is in real time in inspecting state, and the work of maintenance relay K, overhauls the normally closed contact conducting of relay K and play the effect that compensates loop of the door lock, while then pressing compensation reset button G41, just can compensate whole door lock circuit, just can follow according to needs and travel and select button AD by car direction.When compensation reset button, G41 is late for, and the button automatic spring of compensation reset button G41 resets, and has no longer compensated door lock.When service work completes, then operation sheet double-pole double throw switch SPDT reset, connect maintenance circuit MK, cut off cross-over connection equalizer circuit MF, thus the safety of playing and protective effect.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.
Through facts have proved; this fender guard plays a part convenient and raises the efficiency in maintenance work; compensation fender guard is 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.
