Abstract
The utility model relates to a manual turning gear of a traction machine, which is arranged on the traction machine with a traction sheave and is characterized in that the traction sheave is fixedly connected with a big gear; the traction machine beside the big gear is provided with a shaft sleeve; the traction sheave is also provided with a pinion with a turning gear hand wheel; the pinion is movably connected with the shaft sleeve; and the pinion is meshed with the big gear. In the manual turning gear of the traction machine of the utility model, the pinion meshed with the big gear and the turning gear hand wheel have effect of increasing the rotating torque; and when an elevator car stops between two landings due to a fault or power failure, the turning gear hand wheel is rotated to drive the traction sheave to rotate so as to manually drag the elevator car to the safety floor position and then a door is opened so as to bring off stranded passengers. The turning gear has simple structure, is simple and convenient to use and has lower manufacturing cost, long service life and low noise.
Description
Technical field
The utility model relates to a kind of turning gear, particularly relates to a kind of hand turning gear of permanent-magnet synchnorous gearless dragging machine.
Background technology
Elevator traction machine plays control action to starting acceleration, stable speed operation, the braking deceleration of elevator, directly affects the safety of elevator and the comfort of taking.Permanent-magnet synchnorous gearless dragging machine because little, in light weight, the high efficiency of its volume, reliable and stable, operate steadily, noise is low, long service life and characteristics such as be easy for installation and maintenance, and has obtained promotion and application widely.Permanent-magnet synchnorous gearless dragging machine comprises drg, coder, traction sheave and permagnetic synchronous motor, traction sheave and motor coaxle are installed, drg also with the same axle mounting of traction sheave, coder is fixed on the drg, be connected with electric machine main shaft, to realize closed loop control and frequency control operation.When elevator operation break down or the emergency that having a power failure under, generally adopt backup power to make lift car move on to correct position, but backup power cost height not only, when himself et out of order, also can't use, cause certain hidden danger for the use of elevator; Under emergency, also has a kind of method, be that manpower uses clamp specially that the steel rope of elevator is clamped to carry out spacingly, regulate elevator car position with chain block, but that this operation is required great effort very much is time-consuming, sometimes can't in time save stranded passenger, cause harmful effect.
The utility model content
The purpose of this utility model promptly provides a kind of hand turning gear of towing machine, use very simple and convenient, the problem that can solve well that elevator has a power failure or save stranded passenger during fault, and simple in structure, low cost of manufacture, long service life, noise is low.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of hand turning gear of towing machine, be arranged on the towing machine with traction sheave, and it is characterized in that, captive joint one big gear wheel on described traction sheave, the towing machine of described big gear wheel side is provided with axle sleeve; Other is provided with a miniature gears with handwheel, and described miniature gears and described axle sleeve flexibly connect, and described miniature gears meshes with described big gear wheel.
Preferably, described miniature gears is provided with pinion shaft, and described handwheel is fixedly connected on described pinion shaft one end; Described towing machine is provided with lays axle sleeve, and the described pinion shaft other end cooperates with described axle sleeve or the described axle sleeve of laying.
Preferably, described big gear wheel and described miniature gears are the spiral fashion straight bevel gear through hardening.
Preferably, the transmitting ratio of described big gear wheel and described miniature gears is greater than 10.
The hand turning gear of towing machine of the present utility model, with be set with big gear wheel on the traction sheave of the electric machine main shaft of towing machine interlock, be connected with the handwheel that increases rotating torque with big gear wheel ingear miniature gears, when barrier or power failure cause lift car to be parked between two stops for some reason, rotate handwheel, drive traction sheave rotation to the safe floor position, is opened the manual traction of lift car and can be rescued stranded passenger with door.This turning gear is simple in structure, uses simple and conveniently, and manufacturing cost is lower, and long service life, and noise is low.
Description of drawings
Fig. 1 is the structural representation of the hand turning gear of towing machine of the present utility model.
1-towing machine among the figure, the 2-traction sheave, the 3-big gear wheel, the 4-handwheel, the 5-miniature gears, the 6-pinion shaft, 7-lays axle sleeve, the 8-axle sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of hand turning gear of towing machine is arranged on the towing machine 1 with traction sheave 2, and by key captive joint one big gear wheel 3, the towing machine 1 of big gear wheel 3 sides is provided with axle sleeve 8 on traction sheave 2; Other is provided with a miniature gears 5 with handwheel 4, and miniature gears 5 flexibly connects with axle sleeve 8, simultaneously miniature gears 5 and big gear wheel 3 engagements.
Miniature gears 5 is provided with pinion shaft 6, and handwheel 4 is fixedly connected on pinion shaft 6 one ends; Towing machine 1 is provided with lays axle sleeve 7, the axle sleeve 8 of pinion shaft 6 other ends and big gear wheel 3 sides or lay axle sleeve 7 and cooperate.
When elevator normally moved, the pinion shaft 6 of miniature gears 5 inserts to be laid in the axle sleeve 7, lays axle sleeve 7 and is arranged on the position that can save the elevator running space on the towing machine 1; When barrier or power failure cause lift car to be parked between two stops for some reason, pinion shaft 6 ends of miniature gears 5 are inserted in the axle sleeve 8 of big gear wheel 3 sides on the towing machine 1, after miniature gears 5 aligns engagement with big gear wheel 3, rotate handwheel 4, drive traction sheave 2 rotations, can reduce the operating effort of manual traction, easily realize the upper and lower motion of lift car, the manual traction of lift car to the suitable level position, is opened door and rescued stranded passenger.
Big gear wheel 3 and miniature gears 5 are through the spiral fashion straight bevel gear that hardens, and make this turning gear very wear-resisting, have very long service life, and noise is also lower during use.
Big gear wheel 3 is 12 with the transmitting ratio of miniature gears 5, and the driving force of generation can satisfy the elevator operation code requirement.
