Abstract
The utility model relates to a manual barring gear of toothless hauler, it is equipped with the flank of tooth on the braked wheel rim that fuses with the driving sheave, this flank of tooth and the pinion intermeshing who has rocking arm or disc hand wheel on installing the support, it does not have middle reduction gears, also can be like there being the tooth hauler, under the condition that does not have emergency power source, rotates rocking arm or disc hand wheel, and manpower makes the car move from top to bottom, the utility model discloses simple structure, and pinion dismantlement are easy, greatly reduced elevator device's cost and the reliability that has improved equipment operation.
Description
The utility model relates to a kind of elevator annex, especially a kind of hand turning gear of elevator traction machine.
The towing machine that elevator is used, domestic most employing has the tooth towing machine, middle palpus speed reduction gearing, when elevator was installed or keep in repair, the handwheel with being installed in electrical motor (speed end) device made elevator do upper and lower motion under the effect of manpower.Abroad in recent years, progressively substitute the tooth towing machine with anodontia towing machine, but because anodontia towing machine has been cancelled middle speed reduction gearing, therefore, it can not be as the tooth towing machine is arranged, reach operation under the elevator emergency state by manpower, but make the bridge railway carriage or compartment under the elevator faults state, carry out upper and lower operation with the way that emergency source of electrical power is set, but this emergency source of electrical power not only capacity is big, the cost height, and under the situation of emergency source of electrical power also et out of order, car just can not be done upper and lower operation.
The purpose of this utility model is defective and the deficiency that is at prior art, makes anodontia traction function as the tooth towing machine is arranged, and realizes operating function under the elevator emergency state with manpower, reduces equipment cost with this, improves reliability of operation.
Task of the present utility model is achieved in that an end of traction sheave is connected with brake wheel, geared surface on the wheel rim of this brake wheel, and this flank of tooth is meshed with miniature gears on being installed on support, and miniature gears is connected with rocking arm or disk handwheel by adapter shaft; After the wheel shaft of miniature gears inserts bearing hole on the support, with bearing pin to fixing with support.
Traction function that the utility model is anodontia is as the tooth towing machine is arranged, rotate rocking arm or disk handwheel, just can make the steel rope rolling-in of towing machine or loosen, thereby reach and not only do not have intermediate reduction gear mechanism but also can be without emergency electric power source, make the upper and lower operation of car by manpower, reduce the equipment investment of whole lift appliance, improved reliability of operation.
Below in conjunction with accompanying drawing, the utility model will be further described.
Accompanying drawing is a structural representation of the present utility model.
Shown in the accompanying drawing, brake wheel 1 is cast as one with traction sheave 10, geared surface 2 on the wheel rim of brake wheel 1, the flank of tooth 2 intermeshes with miniature gears 3, and miniature gears 3 is installed on the support 4, and bearing 7 preferably is housed on the support 4, after the wheel shaft of miniature gears 3 inserts bearing 7 holes, axially fixed with pin 5, support 4 is installed on the electric motor end cap 6 of traction sheave 10, and miniature gears 3 is connected with rocking arm or disk handwheel 9 by adapter shaft 8.The miniature gears 3 that has rocking arm or disk handwheel 9, when needing, behind the insertion bearing hole, can be simple and easy fixing with support, dismounting is easily.When moving at ordinary times, miniature gears 3 can be lifted down, and like this, towing machine is the gearless grating when operation.
During use, rotate rocking arm or disk handwheel 9, drive little tooth axle 3 and rotate thereupon, thereby the brake wheel 1 that is engaged with is also rotated, because brake wheel 1 is an integral body with traction sheave 10, so the rotation of traction sheave makes lift car do upper and lower operation by steel rope.
The utility model is simple in structure, and cost is low, help applying of anodontia towing machine, especially can be applied widely in residential lift.
Claims (2)
1, a kind of hand turning gear of anodontia towing machine, an end that it is characterized in that towing machine is connected with braking, the wheel rim of this brake wheel is provided with the flank of tooth (2), it and miniature gears (3) engagement that is installed on the support (4), this miniature gears (3) is connected with rocking arm or disk handwheel (9) by adapter shaft (8).
2, the hand turning gear of anodontia towing machine according to claim 1, it is characterized in that described miniature gears (3) wheel shaft inserts bearing (7) hole on the support (4) after, axially use pin (5) fixing.
