Mostly the lifting table that uses at present is the electric hydraulic lifting table, by the motor-driven hydraulic efficiency pressure system, drives lifting platform by hydraulic actuating cylinder; Complex structure, the hydraulic part accuracy of manufacture requires high, when using the hydraulic actuating cylinder time long; Cylinder seal will wear and tear, and causes leakage of oil, all pollutes in case the whole water surface of leakage of oil occurs; Thereby can't in water, use, cause the lifting table application scenario to receive certain limitation.
In megaevent or stage performance or some special occasions; Sometimes need two platform synchronization liftings, prior art adopts with synchronous valve, synchronized cylinder or synchronous motor mostly, but has tested for many years; Do not reach synchronous effect yet, and cut and consumed a lot of human and material resources.
Summary of the invention
The object of the invention is to provide a kind of steel rope special-purpose lift car, and is simple in structure, and do not receive the influence of applied environment, synchronization lifting fast.
To achieve these goals, the present invention adopts following technical scheme:
The special-purpose lift car of a kind of steel rope comprises:
The stage body that goes up and down more than one comprises platform, base and the lifting support between platform and base;
An above motor;
An above winch, the steel rope of under motor-driven, reeling;
Running block, corresponding with up-down stage body quantity, be installed on the lifting support;
The fixed pulley group, corresponding with up-down stage body quantity, be fixed on the base through mount pad; With
Steel rope, an end links to each other with mount pad, alternately walk around the fixed pulley of movable pulley and fixed pulley group of running block after, its other end is wound on the lifting drum.
In the embodiment of the invention, said winch and number of motors are suitable, and up-down stage body quantity is 2 times of motor.
In the embodiment of the invention, be connected with the transition pulley and a starter pulley that links to each other with base of the leading sheave of a wheel shaft and lifting drum parallel axes, deflection sheave that is used to change the steel rope direction, wheel shaft and lifting drum axis normal between winch and the up-down stage body successively through steel rope.
In the embodiment of the invention, the up-down stage body is two that laterally arrange.
In the embodiment of the invention, lifting support is the connecting rod that is hinged to fork-shaped more than a group.
In the embodiment of the invention, winch is a double drum winch, twin.
Beneficial effect of the present invention:
Through driven by motor winch haulage cable, realized the rising or the reduction of up-down stage body by the variation of pulley room distance, simple in structure, and do not receive the influence of applied environment.
Description of drawings
Fig. 1 looks scheme drawing for master of the present invention.
Fig. 2 is a schematic top plan view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details, following explanation only is exemplary, does not limit protection scope of the present invention.
With reference to accompanying drawing 1,2; The special-purpose lift car of a kind of steel rope; Comprise two up-down stage bodies 10 and driver train; Up-down stage body 10 comprises platform 101, base 102 and the lifting support 103 between platform 101 and base 102, and lifting support 103 is a pair of connecting rod that is hinged to fork-shaped, and driver train is that steel rope drives the up-down that realizes up-down stage body 10.
Said driver train comprises a motor 2, winch 3, running block 11, fixed pulley group 13 and a steel rope 12, and winch 3 is used for coiling steel rope 12 under motor 2 drives; Running block 11 is corresponding with up-down stage body 10 quantity, is installed on the lifting support 103; Fixed pulley group 13 is corresponding with up-down stage body 10 quantity, is fixed on the base 102 through mount pad 14; Steel rope 8 one ends link to each other with mount pad 14, alternately walk around the fixed pulley of movable pulley and fixed pulley group 13 of running block 11 after, its other end is wound on the winch roller.
With reference to accompanying drawing 1; Consider that up-down stage body 10 of the present invention maybe be in same working environment with driver train when using; The leading sheave 5, one that is provided with a wheel shaft and winch roller parallel axes between winch 3 and the up-down stage body 10 successively is used to change the transition pulley 7 and a starter pulley 8 that links to each other with base 102 of the deflection sheave 2 of steel rope direction, wheel shaft and winch roller axis normal; Motor 2 can be arranged on the erecting frame 1 with winch 3 during practical application, and erecting frame 1 connects preparatory backing plate 3 so that deflection sheave 2 and transition pulley 7 are installed through strut bar 4.
Winch 3 is a double drum winch, twin in the practice, and motor 2 drives two steel ropes 12 simultaneously and leads to 10 controls of two up-down stage bodies respectively and carry out synchronization lifting.
The present invention does power through motor 2 and drives winch 3 and draw two steel ropes 12 and lead to two up-down stage bodies 10 respectively and carry out synchronization lifting; If two platforms are different when high, the available active spanner was mediated to steel rope, till two platforms synchronously, to reach satisfied effect in going up and down kind.
Can design a plurality of up-down stage bodies 10 as required in the practice, up-down stage body 10 quantity are 2 times of motor 2, and winch 3 is suitable with motor 2 quantity, and the quantity of the movable pulley of running block 11 and fixed pulley group 13 fixed pulleys can be provided with a plurality of as required.
Above embodiment only is used to explain technical scheme of the present invention but not to its restriction; Although the present invention is specified through embodiment; Under the field personnel should make amendment or the part technical characterictic is equal to replacement with reference to concrete mode of the present invention; But under the spirit that does not break away from technical scheme of the present invention, above-mentioned change or be equal to replacement and should belong in the technical scheme scope that the present invention asks for protection.
