Abstract
The invention discloses a hydraulic lifting stroke two-stage amplification device for a multilayer stereo garage, especially for a high-rise stereo garage. The device is small in occupied space and flexible and diverse in structure. A hydraulic oil cylinder 2 is installed in a rear cross beam 3 of a transverse moving frame of lifting transverse moving type parking equipment, a fixed chain wheel 1 and a movable chain wheel 4 are installed at the front end and the rear end of the hydraulic oil cylinder respectively, and a chain wheel set is formed by twining a chain. The chain wound out of the chain wheel set is not directly fixed to a vehicle bearing plate 7 but fixed to a movable pulley block 5. The movable pulley block 5 and a fixed pulley block 6 installed at the front end of the transverse moving frame form a pulley block by being wound through a steel wire rope, and then the steel wore rope wound out of the pulley block is fixed to the front end and the rear end of the vehicle bearing plate 7. Amplification for the first time is conducted by the fixed chain wheel 1 and the movable chain wheel 4 which are installed on the hydraulic oil cylinder 2, so the moving distance of the movable pulley block 5 is several times than displacement of a piston rod of the hydraulic oil cylinder 2. The pulley block formed by the movable pulley block 5 and the fixed pulley block 6 can carry out secondary amplification on movement of the movable pulley block 5. By means of two-time amplification, the stroke of the hydraulic oil cylinder 2 is sufficiently amplified, and the final amplification time of the device is the product of two-time amplification times.
Description
Technical field
The present invention relates to a kind of for multi-storied garage lifting travel two-stage amplifying device.
Background technology
At present, the lifting of lifting cross sliding type mechanical parking equipment drives, and great majority adopt motor to come haulage cable or chain to reach the object that makes vehicle-containing elevating movement by transmission mechanism.Along with the increase of the number of plies, meet certain picking up the car the time, will inevitably accelerate the speed of service of vehicle-containing, the power of lifting motor; Meanwhile, after hoisting depth increases, the length that promotes wire rope used also can increase, and corresponding drum diameter and length also can increase thereupon, and these all can increase the construction cost in garage.For addressing the above problem, also there is part producer to adopt hydraulicdriven mode to solve the problems referred to above, this mode is to utilize hydraulic jack to replace Motor Drive, pulley is installed in the rear and front end of oil cylinder, winding by wire rope forms assembly pulley by front and back pulley, the flexible stroke that can be undertaken to a certain degree by the amplification of assembly pulley of oil cylinder amplifies like this, thereby reaches the object that improves the vehicle-containing speed of service.But in this method, oil cylinder itself has taken a part of space, make the total kilometres of pulley not only be subject to the constraint of traversing framework physical dimension, be also subject to the restriction of oil cylinder self length, therefore the multiple that its stroke amplifies is restricted, can not raise too high.
Summary of the invention
The invention provides a kind of for multilayer high-level stereo garage hydraulic lifting stroke two-stage amplifying device particularly.This device occupies little space, and flexible structure is various, and reliability is high, stable, uses number of elements few, and cost is low.
This device can be realized in the following manner: in the traversing framework of lifting cross sliding type parking equipment, hydraulic jack 2 is installed in rear cross beam 3, determines sprocket wheel 1, movable sprocket 4 is arranged on respectively the rear and front end of hydraulic jack, and become chain wheel set by the winding-shaped of chain.The chain that this chain wheel set lays out is not directly fixed on vehicle-containing 7, but is fixed on running block 5.Running block 5 be arranged on the winding by wire rope of fixed pulley group 6 on traversing frame front end and form again one pair of assembly pulley, the wire rope laying out from this pair of assembly pulley is fixed to the rear and front end of vehicle-containing 7 again.
By being arranged on the amplification for the first time of determining sprocket wheel 1 and movable sprocket 4 on hydraulic jack 2, the distance that running block 5 is moved is the several times of hydraulic jack 2 piston rod displacements.And running block 5 can carry out secondary amplification by the movement of running block 5 with the formed assembly pulley of fixed pulley group 6.After amplify these two places time, the stroke of hydraulic jack 2 is fully amplified, and this install the product that final multiplication factor is twice multiplication factor.
This cover system compared with prior art has following advantage and beneficial effect:
1, adopt two-stage stroke enlarger, and the multiplication factor of the system product that is twice multiplication factor, can increase considerably the multiplication factor of total kilometres.
2,5 groups of movable pulley are arranged on longeron, can make full use of the length of longeron, have improved to greatest extent the appearance rope space of wire rope.
3, in the installation site of running block without the power amplifying, its power comes from the traction of rear end chain.Can effectively avoid the impact of power set on running block moving displacement like this.
4, the two-stage enlarger of this device is relatively independent, and mounting means is versatile and flexible, can be front or rear, can a left side can be right, up and down.
5, owing to thering is two-stage enlarger, can according to the actual requirements the multiplying power of two groups of enlargers be allocated, reach the requirement of different total enlargement ratio, use very flexible.In the situation that oil cylinder stroke is constant, by increasing the multiplication factor of pulley system, can reach identical multiplication factor, even larger multiple, thus reduced the requirement to oil cylinder stroke.
6, first group of enlarger of device can adopt various ways to realize, and can use hydraulic drive, also can adopt electric-motor drive, and the medium of transmission can be chain, can be also wire rope, gear etc.As shown in Figure IV, for first order enlarger adopts hydraulic drive.

The specific embodiment
Below the present invention is further illustrated, but the implementation of this stroke amplification device is not limited to this.
As shown in Figures 1 and 2, the traversing framework rear cross beam 3 of multi-storied garage is hollow structure, is separately installed with hydraulic jack 2, determines sprocket wheel 1 and movable sprocket 4 in rear cross beam.One end of chain is fixed on determines on sprocket wheel 1, then will determine sprocket wheel 1 and movable sprocket 4 and be wound in one pair of assembly pulley, and the chain laying out from chain wheel set is fixed to running block 5.
One end of other two wire rope is fixed on to the front end of traversing framework, again running block 5 and the fixed pulley group 6 that is installed on traversing frame front end are wound in to two pairs of new assembly pulleys, two wire rope that lay out are fixed on the rear and front end of vehicle-containing after two leading blocks.
By being arranged on the amplification for the first time of determining sprocket wheel 1 and movable sprocket 4 on hydraulic jack 2, the distance that running block 5 is moved is the several times of hydraulic jack 2 piston rod displacements.And running block 5 can carry out secondary amplification by the movement of running block 5 with the formed assembly pulley of fixed pulley group 6.After amplify these two places time, the stroke of hydraulic jack 2 is fully amplified, and this install the product that final multiplication factor is twice multiplication factor.
The first order enlarger of device also can adopt the mode of the electric-motor drive shown in Fig. 3 to drive.Because the range of running block is no more than the length of longeron, so the drum diameter of motor and length can be processed smallerly.
