Abstract
Head sheave of hoister maintenance closing appliance of the present utility model, the start button comprising PLC parametric controller and be connected with described PLC parametric controller, described start button controls the start and stop of described Hydraulic Station for Hoister by described PLC parametric controller, the C/LOOP that described start button and described PLC parametric controller form also is provided with change-over swith, described change-over swith is controlled by pluggable key knob, then key is pulled up to carry with by the position that change-over swith to be got to "Off" by key knob and is overhauled head sheave by service personnel, even if now hoister is pressed start button and also cannot be started Hydraulic Station for Hoister.Between turn(a)round, gig is in braking mode, ensure that the safety of service personnel.
Description
Technical field
The utility model prevents unexpected closing appliance, particularly a kind of closing appliance be used on gig when relate to a kind of maintenance.
Background technology
When head sheave of hoister et out of order, service personnel needs to overhaul the head sheave of liftoff tens of meters to inspection platform, and service personnel, when overhauling head sheave, is contacted by interphone with the hoister being positioned at ground.Can there is poor TV signal in maintenance process, driver opens by mistake the phenomenons such as machine, and now gig drives head sheave to rotate, and this can cause serious personal injury to maintainer.
Utility model content
The goal of the invention of the application is the above-mentioned technical matters existed when solving current head sheave of hoister maintenance, and provides a kind of safe and reliable head sheave of hoister to overhaul closing appliance, ensures the safety of maintainer.
In order to complete the goal of the invention of the application, the application by the following technical solutions:
Head sheave of hoister maintenance closing appliance of the present utility model, the start button comprising PLC parametric controller and be connected with described PLC parametric controller, described start button controls the start and stop of described gig by described PLC parametric controller, the C/LOOP that described start button and described PLC parametric controller form also is provided with change-over swith, and described change-over swith is controlled by pluggable key knob.
Change-over swith described in the utility model is rotor switch, and described rotor switch is also connected with indicator lamp.
Change-over swith described in the utility model is arranged on described PLC parametric controller, and described PLC parametric controller is provided with the counterbore for installing described change-over swith, and counterbore is provided with seal cover cap.
Change-over swith described in the utility model is arranged on inspection platform, and described inspection platform is provided with the counterbore installing described change-over swith, and counterbore is provided with seal cover cap.
Head sheave of hoister maintenance closing appliance of the present utility model is compared with prior art distinguished and is: service personnel is before overhauling head sheave, gig stops and being in safety arrestment state by hoister, stop brake for elevator hydraulic motor, then key knob is pulled up to carry with by the position that change-over swith to be got to "Off" by key knob and is overhauled head sheave by service personnel, even if now hoister is pressed start button and also cannot be started elevation scheme brake hydraulic station.Between turn(a)round, gig is in braking mode, ensure that the safety of service personnel.After head sheave maintenance terminates, change-over swith to be got to the position of "ON" by the key knob of head sheave maintenance closing appliance by service personnel, and hoister can open elevation scheme brake hydraulic station, operates gig.
Accompanying drawing explanation
Fig. 1 is head sheave of hoister of the present utility model maintenance closing appliance integral structure schematic diagram;
Detailed description of the invention
As shown in Figure 1, the head sheave of hoister maintenance closing appliance of the present embodiment, comprise PLC parametric controller 3 and start button 2, start button 2 is connected with PLC parametric controller 3, start button 2 controls the start and stop of elevation scheme brake hydraulic station by PLC parametric controller 3, the C/LOOP that start button 2 and PLC parametric controller 3 form also is provided with change-over swith 1, change-over swith 1 is controlled by pluggable key knob, service personnel is before overhauling head sheave, gig stops and being in safety arrestment state by hoister, stop brake for elevator hydraulic motor, then key knob is pulled up by the position that change-over swith 1 to be got to "Off" by key knob and is carried with by service personnel, then head sheave is overhauled, even if now hoister is pressed start button 2 and also cannot be started gig, ensure that the safety of service personnel.
Change-over swith 1 is rotor switch, particularly, include four contacts, be respectively the first contact 12, contact 11, second, the 3rd contact 13 and the 4th contact 14, first contact 11 is connected with wire with the second contact 12, first contact 12, contact 11, second is connected under normal circumstances, cuts off Hydraulic Station, rotate change-over swith during head sheave maintenance, first contact 12, contact 11, second disconnects, pull out key knob, make the first contact 12, contact 11, second remain open state, again cannot start Hydraulic Station.With key knob, change-over swith is turned to normal position after maintenance, the first contact 12, contact 11, second is connected, and pressing start button can start Hydraulic Station.
Preferably, change-over swith 1 is also connected with indicator lamp, when change-over swith 1 gets to position (namely change-over swith turns to the 3rd contact 13 or the 4th contact 14) of "Off", indicator lamp is for red, the starting-up later time of prompting service personnel brake for elevator hydraulic motor is cut off, can not start Hydraulic Station and forbid gig work by watchful hoister simultaneously yet, when change-over swith 1 gets to the position of "ON", indicator lamp is for green, and prompting can normal running gig.
Change-over swith 1 can be arranged on PLC parametric controller 3, PLC parametric controller 3 is provided with the counterbore for installing change-over swith 1, counterbore installs seal cover cap, like this after key knob is unplugged, lock seal cover cap, hoister and other staff cannot manipulate change-over swith 1, guarantee the safety of service personnel.
Change-over swith 1 also can be arranged on inspection platform, and inspection platform is provided with the counterbore installing change-over swith 1, and counterbore installs seal cover cap, is the safety in order to ensure service personnel equally.
After head sheave maintenance terminates, change-over swith 1 to be got to the position of "ON" by the key knob of head sheave maintenance closing appliance by service personnel, and hoister can operate gig.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
