The description that reaches the back in conjunction with the accompanying drawings is described in further detail one embodiment of the present of invention, wherein:
The perspective illustration of a bont of Fig. 1, it have load-carrying supplementary device that two linear drive apparatus and one is made up of two clutch release slave cylinders and
Block schematic diagram that principle of work is elaborated of Fig. 2.
The specific embodiment
The bont that is described as embodiments of the invention in Fig. 1 is used for the lifting and the reduction of weight.Each weight is placed on the bay-lift 10 as the weight storing apparatus, has two raceways 11 that are installed on this bay-lift 10 to carry out work here.Other devices also can replace raceway 11 to be used for the light exercise of weight, and as the air cushion guide piece, slide rail rolls all things that also can expect such as rail or transportation device under the most easy situation.
On a plate-shaped base 12, there are two vertical linear drive apparatus 13,14 medially to be installed on the opposite side of pedestal 12 respectively, pedestal also can be frame shape or have other a basic support.Here be such as the linear drive apparatus 13,14 of electrically operated or hydraulic pressure.From the longitudinal slot 9 of linear drive apparatus 13,14, given prominence to and from described transparent view, can only see one actuator 15.This actuator 15 is located on linear drive apparatus 13,14 driver element separately, as being installed on the hydraulic piston under the situation of a fluid pressure drive device, or is being installed under the situation of a motorized motions on axle, driving belt or the magnet rotor.Here all linear drive apparatus types of knowing can be used.A hydraulic drive cylinder as linear drive apparatus for example can be made of the seam formula cylinder of knowing, and as disclosed by EP 0 612 377 B1 or EP 1 182 359 B1, wherein the slit of actuator by cylinder is outstanding, cylinder in all the other zones by elastic seal.
Two relative angles as pedestal 12 have two hydraulic cylinders 16,17 vertically to be provided with, they are used to produce a balancing force that depends on the weight that each is to be lifted, no matter corresponding thus weight weight size must produce identical propulsive effort all the time by linear drive apparatus 13,14.As two linear drive apparatus 13,14 such as be set total propulsive effort of a 500N, they have reached optimum degree to this, if and the weight that must to lift a gravity be 8000N, then the hydraulic cylinder 16,17 must produce a balancing force that is total up to 7500N, in other words, must load it with a constant fluid pressure that produces the 7500N balancing force.
As long as the piston stroke length that needs is not excessive, can also use seam formula cylinder or conventional cylinder as hydraulic cylinder 16,17.That yes is variable for the setting of linear drive apparatus 13,14 and clutch release slave cylinder 16,17 and quantity.Therefore such as also can the hydraulic cylinder 16,17 that be used to produce a balancing force be installed all on all four angles of pedestal 12, perhaps carry out in opposite mode with the setting between the linear drive apparatus at clutch release slave cylinder.In order to place or promote weight, a side of bay-lift 10 should keep unimpeded by rights at this.
Linear drive apparatus 13,14 also can be provided with in a lifting cage or elevator shaft or winding shaft with the structure of clutch release slave cylinder 16,17.In order to ensure the stability of necessity of bont, vertical linear drive apparatus 13,14 and hydraulic cylinder 16,17 must be propped up with diagonal brace with fixing in the mode that requires certainly in addition.In scheme drawing shown in Figure 1, omitted describing to such diagonal brace or hoistway in order to simplify.
