The speed reducer is composed of a first-stage speed reducer and a two-stage speed reducer, wherein, the first-stage speed reducer adopts a speed reducer with no self locking.

Description

The different power bi-motor main power plant of vertical rotary mechanical parking equipment

The utility model belongs to the garage parking technical field, relates to a kind of different power bi-motor main power plant of vertical rotary mechanical parking equipment.

The main motion of vertical rotary mechanical parking equipment is the vertical circulation motion, power set as main motion all adopt the motor reducer of two equal-wattages to start the hinge wheel that drives the rear and front end simultaneously at present, and the power sum of two main motors is promptly calculated by the contained suitable difference of stopping vehicle number in both sides, two hinge wheel centers by parking stall difference, and must satisfy the ultimate load operating mode---a side is all carried quota and is decided the requirement that the suitable parking of weight, opposite side all do not have car.Like this, the number of harnessing an animal to a cart is that the power sum of 30 equipment two main motors must be 15 calculating by the parking stall difference, should reach more than the 45KW.When parking stall, both sides difference seldom the time, present the phenomenon of low load with strong power, motor power factor is very low, and (C08 Φ=0.4-0.7), efficient reduce a lot, and power attenuation is multiplied, and the starting-impact frequency of other power equipments of co-variation depressor is strengthened.

The purpose of this utility model is that a kind of existing above-mentioned defective of power set that can solve existing vertical rotary mechanical parking equipment effectively will be provided, and has the different power bi-motor main power plant of the vertical rotary mechanical parking equipment of good energy-conserving effect.

The purpose of this utility model realizes with the following methods.The different power bi-motor main power plant of this vertical rotary mechanical parking equipment comprises main motor, auxiliary motor, hinge wheel, circulation dragging chain on hinge wheel, one-level reducer pinion is arranged respectively on the output shaft of main motor and auxiliary motor, two one-level reducer pinions all form the one-level reducer with an one-level reducer gear wheel engagement, two gear wheel wheel shafts link into an integrated entity by shaft coupling and synchronizing shaft, the outer end of two gear wheel wheel shafts all is connected with a two stage reducer, the output shaft of each two stage reducer is connected with the wheel shaft of a hinge wheel respectively, when the rated output power of main motor is main power plant ultimate load operating mode 2/3 of required general power, when the rated output power of auxiliary motor is main power plant ultimate load operating mode 1/3 of required general power, the one-level reducer adopts non-self-locking performance reducer.Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model structural representation

Fig. 2 is the utility model transmission principle schematic diagram

Among the figure: 1-hinge wheel 2-two stage reducer gear wheel 3-bearing 4-two stage reducer pinion 5-one-level reducer gear wheel 6-shaft coupling 7-synchronizing shaft 8-one-level reducer pinion 9-master motor 10-auxiliary motor 11-circulation dragging chain 12-carrier 13-is suitable to stop

Contained to fit the difference of stopping vehicle number be S1max in both sides when supposing that the contained suitable difference of stopping vehicle number in two hinge wheels (1) both sides, center when maximum is Smax (side all carry quota decide the suitable parking of weight, the ultimate load operating mode when opposite side does not all have car), actual motion, the parking stall difference Smax of the required peak power output of the utility model during by ultimate load determines, and satisfied by the power sum of main motor (9), auxiliary motor (10).The output rated power of main motor (9) be the required peak power output of the utility model 2/3, the output rated power of auxiliary motor (10) is 1/3 of the required peak power output of the utility model, the one-level reducer of main motor (9), auxiliary motor (10) all adopts non-self-locking performance reducer.During the utility model work, determine originate mode by the ratio of vehicle between issuable parking stall difference S1max in two hinge wheels (1) both sides and maximum parking stall difference Smax that reality has been deposited, that is:

I, when S1max≤1/3Smax, only start auxiliary motor (10), unclamp the brake of main motor (9);

II, when 1/3Smax＜S1max≤2/3Smax, only start main motor (9), unclamp the brake of auxiliary motor (10);

III, when 2/3Smax＜S1max≤Smax, main motor (9), auxiliary motor (10) start simultaneously.

Because the one-level reducer do not have self-locking performance, when operating mode I, main motor (9) is by from the reverse driving of low speed end, and is same, and when operating mode II, auxiliary motor (10) is by from the reverse driving of low speed end.Since the dynamic moment of inertia of slave motor and one-level reducer only be vehicle load the equivalent dynamic moment of inertia about 1/50, so the power attenuation of Chan Shenging is atomic therefrom, can ignore.After main motor (9) or auxiliary motor (10) startup, one-level reducer pinion (8) on the motor output shaft drives one-level reducer gear wheel (5), through shaft coupling (6) and synchronizing shaft (7), power is passed to simultaneously the two stage reducer pinion (4) of both sides, drive hinge wheel (1) by two stage reducer gear wheel (2), circulation dragging chain (11) on hinge wheel is moved up and down, make the carrier (12) that is suspended on the dragging chain in proper order up and down shuttling movement realize the operation of stopping and picking up the car.

The utility model is owing to adopted different power bi-motor, in the operating process, according to suitable different situations of stopping on the parking apparatus, start different originate modes, thereby raising motor power factor, reduced the starting-impact to other power equipments of co-variation depressor, compared with power bi-motor main power plant with routine, the utility model can save energy 20-30%.
