Abstract
The utility model discloses a kind of double-cylinder hydraulic elevator, it comprises car, hydraulic ram, track adjusting wheel, steel rope, first hydraulic ram is arranged on below described car, its top piston bar is fixedly connected with cage bottom, second hydraulic ram is arranged on the left side of car, its top piston bar is fixedly connected with steel rope one end, and the steel rope other end is fixedly connected with car top by track adjusting wheel, and described track adjusting wheel is made up of two fixed pulleys.Compared with prior art, this mode is when elevator runs, two hydraulic actuating cylinders work simultaneously, significantly reduce car application force to single hydraulic ram when up-and-down movement, reduce energy consumption, reduce the friction in car movement process and noise, the existence of Double-hydraulic-cylinder also ensure that stationarity in elevator operational process and safety, prevents single hydraulic ram to break down uncontrollable.
Description
Technical field
The utility model relates to mechanical manufacturing field, particularly relates to a kind of double-cylinder hydraulic elevator.
Background technology
Hydraulic hoist is by hydraulicdriven elevator, by hydraulic efficiency power unit (Hydraulic Pump), hydraulic oil is pressed into hydraulic actuating cylinder, makes plunger upward movement, act on car directly or indirectly, make car increase.The decline of car generally makes the fluid in hydraulic actuating cylinder return in fuel tank by deadweight.Hydraulic hoist is safety in tier building, comfortable vertical transport instrument, is also heavy vertical transport equipment the most cheap in factory building, warehouse.In the system of former hydraulic hoist, much all adopt single cylinder to support, the car size due to overload hydraulic elevator is general comparatively large, and compages rigidity is poor, this support pattern unbalance loading can have a strong impact on the operation balance of elevator time larger, the wearing and tearing of aggravation guide rail.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of double-cylinder hydraulic elevator, namely adopts the elevator car of twin-tub supporting.
The technical scheme that the utility model adopts is: a kind of double-cylinder hydraulic elevator, it comprises car, hydraulic ram, track adjusting wheel, steel rope, first hydraulic ram is arranged on below described car, its top piston bar is fixedly connected with cage bottom, second hydraulic ram is arranged on the left side of car, its top piston bar is fixedly connected with steel rope one end, and the steel rope other end is fixedly connected with car top by track adjusting wheel, and described track adjusting wheel is made up of two fixed pulleys.
Described first hydraulic ram and the second hydraulic ram are multistage hydraulic cylinder, and hydraulic actuating cylinder progression is determined by required adjustable height.
Compared with prior art, the beneficial effects of the utility model are: this mode is when elevator runs, two hydraulic actuating cylinders work simultaneously, significantly reduce car application force to single hydraulic ram when up-and-down movement, reduce energy consumption, reduce the friction in car movement process and noise, reduce manufacturing cost and the installing space of hydraulic actuating cylinder simultaneously, the existence of Double-hydraulic-cylinder also ensure that stationarity in elevator operational process and safety, prevents single hydraulic ram to break down uncontrollable.
Accompanying drawing explanation
Fig. 1 is the structural representation of double-cylinder hydraulic elevator;
Fig. 2 is multistage hydraulic cylinder structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of double-cylinder hydraulic elevator, it comprises car 3, hydraulic ram 4 and 5, track adjusting wheel 1, steel rope 2, first hydraulic ram 4 is arranged on below described car 3, its top piston bar is fixedly connected with bottom car 3, and the second hydraulic ram 5 is arranged on the left side of car 3, and its top piston bar is fixedly connected with steel rope 2 one end, steel rope 2 other end is fixedly connected with car 3 top by track adjusting wheel 1, and described track adjusting wheel 1 is made up of two fixed pulleys.Described first hydraulic ram 4 and the second hydraulic ram 5 are multistage hydraulic cylinder, and hydraulic actuating cylinder progression is determined by required adjustable height.During use, two hydraulic rams work simultaneously, by same pump fuel feed, when Hydraulic Pump starts fuel feeding, when hydraulic oil enters the first hydraulic ram 4, in the first hydraulic ram 4, plunger starts to stretch, car 3 is upwards pushed up, second hydraulic ram 5 starts to shrink, and draws car 3 upward movement by steel cable rope 2, until arrive specified altitude assignment.During decline, cylinder efficient order is just contrary, the first hydraulic ram 4 plunger retraction, and the second hydraulic ram 5 starts to stretch, and car 3 is followed the first hydraulic ram 4 and declined, until assigned address stops, completing elevator working cycle.
