Detailed description of the invention
In Fig. 1,2, guide rail 20 is a kind of Rodless hydraulic cylinder structures, and guide rail 20 passes in and out joint 24 by cylinder body 21, rodless piston 22, piston magnet 23 and hydraulic oil and forms; Cylinder body 21 non-magnet material such as stainless steel tube makes, and cylinder body about 21 two ends are provided with hydraulic oil turnover joint (24) and are connected with hydraulic power system, and rodless piston 22 is placed in cylinder body 21, rodless piston 22 is provided with piston magnet 23.
Compartment system 10 comprises car 14, leads boots 11, car magnet 12 and roller 13, position corresponding with the rodless piston 22 of guide rail 20 on car 14 is provided with leads boots 11, lead on boots 11 and be provided with car magnet 12, car magnet 12 is provided with roller 13, car magnet 12 and piston magnet 23 one_to_one corresponding, opposed polarity produces mutual attractive force relatively, and compartment system 10 is kept fixing relative position with rodless piston 22 by the mutual attractive force of the attracting generation of magnet between all guide rails 20 and compartment system 10 all the time.
Hydraulic power system 30 by oil (31, pump 32, change-over valve 33, flow regulating valve 34, by pass valve 35 and oil pipe 36 etc. form.Hydraulic power system 30 drives rodless piston 22 to move up or down, leave, slow down, brake or stop in cylinder body 21, thus drives compartment system (10) to move up or down, leave, slow down, brake or stop.Because elevator of the present invention is by hydraulic-driven, compartment system (10) does not have cable wire traction, does not have the piston rod of hydraulic actuating cylinder to support, and completely attracts to be suspended between guide rail 20 by magnetic force, therefore is named hydraulic maglev elevator.
Due to compartment system 10 kinematic velocity by hydraulic efficiency pressure system 30 flow regulating valve 34 fix, even if hydraulic efficiency pressure system 30 breaks down, compartment system 10 weighs together with the load-carrying of the inside again, also can only by predetermined speed stable landing, want not become all soon soon, the major accident that disconnected steel wire of tracking-driven elevator is in peril of one's life can never occur, and the safety of visible elevator of the present invention is cocksure.
Due to pressure and the flow of hydraulic system pump 32, determine the load-carrying of elevator and the running velocity of compartment system 10, therefore elevator of the present invention both can be designed to big load elevator, can design express elevator again.
Because Rodless cylinder cylinder body 21 non-magnetic material pipe used can weld prolongation, the volume of hydraulic reservoir 31 can design as required, the structure of compartment system 10 can not be gained in weight, overcome conventional hydraulic elevator layer and hug the more heavily more complicated drawback of higher structure, so elevator of the present invention overcomes the drawback that conventional hydraulic elevator is only applicable to bottom building, and may be used for high-rise building.
The problem that car do not drop reliably can be held about by magnetic force.The strong magnets of a modern very small size just can produce very large suction, can produce huge suction when two strong magnets heteropoles are attracting.By test, by attracting for the strong magnets heteropole of two pieces of diameters 30 millimeters together time, be almost difficult to separated; If by they separately after draw close again time, as not significant care, even hand may be injured.Can prove thus, utilize the principle that strong magnets heteropole is attracting, in four guide rails, four rodless pistons are respectively arranged after several magnet hold mutually with each magnet of leading on boots, car will move with rodless piston simultaneously, think separately all difficult, if need to place under repair to car, all can only drop to ground and carry out, there is not the problem that car can fall down.
In Fig. 3, the same level cross section of each rodless piston 22 is provided with 3 magnet 23; Each same level cross section of leading boots 11 corresponding with magnet 23 on car 14 is provided with 3 magnet 12 too, and the object arranged like this increases attractive force further, can improve load carrying ability further.
Certainly, car 14 size and shape in the horizontal direction can change design according to the different situations in place, and the setting position that magnet is right and quantity also should according to circumstances corresponding changes, and hydraulic efficiency pressure system also will design as the case may be.
