The specific embodiment
In order effectively to suppress lift heavy waving in hoisting process, the invention provides a kind of lifting control method, device, system and a kind of suspender and a kind of elevator machinery of elevator machinery.In this technical scheme, be provided with the first retractor device on each arm type support body of suspender, this first retractor device can wave the controlled motion compensation to hanging beam and lift heavy by the anti-steel rope that shakes, make the relative goods putting platform of hanging beam be in the target balance position, thereby greatly improved the anti-ability of shaking of suspender.For making the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment the present invention is described in further detail.
To shown in Figure 5, suspender one embodiment of the present invention comprises: suspender frame 17 and hanging beam 18, suspender frame 17 comprise box support body 19 and at least three arm type support bodys 20 that stretch out from 19 radiation of box support body, and hanging beam 18 is positioned at the below of box support body 19 such as Fig. 2;
Described suspender also comprises:
Correspondence is arranged at the first retractor device 21 on each arm type support body 20;
Pulley 22 is captiveed joint with an end of the first retractor device 21;
At least one anti-steel rope 23 that shakes, an anti-end that shakes steel rope 23 is involved in the anti-cable drum 24 that shakes that is fixed on the box support body 19, and the other end is walked around pulley 22 and is connected with hanging beam 18.
In order clearly to embody the structure of suspender frame 17 inside, the inside lines of suspender frame 17 are not depicted as hidingly among Fig. 2 to Fig. 4, and in practical structures, because the blocking of suspender frame 17, inner structure is invisible.Among this embodiment, the end that stretches out direction sensing arm shape support body 20 of the first retractor device 21.The effect of hanging beam 18 is to fix with lift heavy, and therefore suppressing waving of lift heavy also is to suppress simultaneously waving of hanging beam 18.Among this embodiment, the box support body 19 of suspender frame 17 and arm type support body 20 are load bearing component, can play on the one hand the effect of protective case, avoid inner structure to be damaged; On the other hand, also play the effect of fixed pedestal for the installation of some parts (such as anti-cable drum 24, the first retractor device 21 etc. of shaking); In addition, the version that box support body 19 and arm type support body 20 combine can reduce the increase of suspender weight significantly in the situation that increases retractor device compensation stroke, therefore, contrast more existing suspenders, and weight is lighter.
In order to make hanging beam 18 and the hanging beam 18 lift heavy (not shown) of hanging reach state of equilibrium, the quantity of arm type support body 20 is at least three, such as thinking three, four or five etc.In the preferred embodiment, the quantity of arm type support body 20 is four, is 90 degree between two adjacent arm type support bodys.For each arm type support body 20, described anti-quantity of shaking steel rope 23 should be at least one, in the preferred embodiment, hanging beam 18 integral body are square, for each arm type support body 20, anti-quantity of shaking steel rope 23 is three, be connected with two limits of being connected with a jiao of hanging beam 18 respectively, suspender integral body prevents that by 12 shaking steel rope is connected with lift heavy, balance is better, the steel rope of cable-stayed type has the passive effect of shaking that subtracts, and the pulley 22 of following of hanging beam 18 and lift heavy fast and stable is moved, and has further improved the anti-effect of shaking.
Please refer to Fig. 2 and shown in Figure 3, for each arm type support body 20, described suspender also comprises guide rail 31 and guide 32, and wherein, described guide rail 31 is arranged at arm type support body 20, and described guide 32 cooperates with guide rail 31 and captives joint with pulley 22.Described guide 32 can be selected slide block or roller etc.The rolling of guide 32 and guide rail 31 or bearing fit can play pulley 22 and support and directional tagging, and suffered resistance when reducing pulley 22 and moving improves the stationarity that pulley 22 moves with the telescopic end of the first retractor device 21.
The type of the first retractor device 21 is not limit, as long as can be flexible along the length direction of arm type support body 20 by control, can be hydraulic actuating cylinder or elastic damper or leading screw etc.Please refer to Fig. 2 and shown in Figure 3, among this embodiment, the first retractor device 21 is hydraulic actuating cylinder, and the piston rod of hydraulic actuating cylinder can be flexible along the length direction of arm type support body 20 by control, and then pulley 22 is captiveed joint with the piston rod end of hydraulic actuating cylinder.When the first retractor device 21 was leading screw (such as ball-screw etc.), the screw mandrel of leading screw can be flexible along the length direction of arm type support body 20 by control, and then pulley 22 is captiveed joint with the screw mandrel end of leading screw.
In technical solution of the present invention, owing to be provided with the first retractor device 21 on each arm type support body 20 of suspender, this first retractor device 21 can shake 23 pairs of hanging beams 18 of steel rope and lift heavy waves the controlled motion compensation by anti-, make hanging beam 18 relative goods putting platforms be in the target balance position, therefore, but establishment lift heavy waving in hoisting process improved the anti-ability of shaking greatly; On the other hand, the steel rope of cable-stayed type also has the passive effect of shaking that subtracts, and the pulley 22 of following of hanging beam 18 and lift heavy fast and stable is moved, and has further improved the anti-effect of shaking.
As shown in Figure 3, described suspender also comprises rotating disk 25, connecting rod 26 and the second retractor device 27, wherein,
Described rotating disk 25 comprises pallet 29 and the gear turntable 30 that can rotate relative to pallet 29, and described gear turntable 30 is captiveed joint with box support body 19;
