For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of building hoist leveling device, first contactless switch that comprises control lifting motor prograde circuit break-make, second contactless switch of control lifting motor circuit for reversing break-make, be provided with the contactor control loop, the magnet coil of the magnet coil of described first contactless switch and second contactless switch is connected in parallel on the described contactor control loop, described contactor control loop is provided with and just changes hands moving switch and counter-rotating hand switch, electric current is by just changing hands the magnet coil that moving switch flows to first contactless switch, and electric current flows to the magnet coil of second contactless switch by the counter-rotating hand switch; Be provided with just change hands moving switch in parallel just change the self-locking branch road and with counter-rotating hand switch counter-rotating self-locking branch road in parallel, the described self-locking branch road that just changeing is provided with first normally open contact and first normally closed interlock; Described counter-rotating self-locking branch road is provided with second normally open contact and second normally closed interlock; Described first normally open contact is connected with described first contactless switch, and described second normally open contact is connected with described second contactless switch, and described first and second normally closed interlock is connected with travel switch, and the inductive head of described travel switch is installed on the elevator cage.With the cage lifter uphill process is that example describes, when cage soon is raised to designated floor, the workmen can unclamp and just change hands moving switch, since first contactless switch be in electric work state, first normally open contact that is just changeing the self-locking branch road is in closure state, just changeing the self-locking branch road and be in on-state, electric current can by just change the self-locking branch road make the contactless switch of winning continue electric work.Cage continues to rise, after the inductive head of the travel switch on the cage is touched, the action of triggering travel switch, first normally closed interlock on the main story self-locking branch road is disconnected, thereby cut off the current return of the magnet coil of first contactless switch, the first contactless switch dead electricity, disconnecting lifting motor is just changeing path, lifting motor is quit work, reach the flat bed action of cage lifter uphill process.The flat bed principle of cage lifter decline process is the same when rising, and no longer is described in detail.Circuit structure of the present utility model is simple, and cost is low, and can satisfy the flat bed demand of building hoist, effectively reduces the power consumption of lifting motor.
As improvement, logical being provided with of described lifting motor prograde circuit just changeed normally open contact, and the described normally open contact that just changeing is connected with described first contactless switch; Described lifting motor circuit for reversing is logical to be provided with the counter-rotating normally open contact, and described counter-rotating normally open contact is connected with described second contactless switch.
As improvement, described contactor control loop is provided with main supply switch, and electric current flows to described moving switch and the counter-rotating hand switch just changed hands after by main supply switch respectively.
As improvement, the inductive head of described travel switch is installed in the bottom or the top of cage, and the bottom or the top of each layer of elevator frame are provided with corresponding impact head.By the setting of inductive head, can change the stop position of cage, thereby adjust the flat bed of cage lifter more accurate.
The beneficial effect that the utility model is compared with prior art brought is:
Circuit structure is simple, and cost is low, and can satisfy the flat bed demand of building hoist, and operating efficiency improves;
Effectively reduce the power consumption of lifting motor, 10 hour calculate by work every day, and every day, every cage lifter was saved 6 degree electricity, and the whole nation is with 200,000 calculating, and can be national brownout 1,200,000 degree every day.
