Background technology
The scissor-type job platform is broad-spectrum aloft work specialized equipment, its scissor-type physical construction, and it is safer that bay-lift is more stablized, and being equipped with drive system can Efficient and Flexible move, thereby provides safeguard for efficiency operation.Because job platform is more roomy and have advantages of high bearing capacity, make bigger, the also suitable many people operations simultaneously of aloft work scope, be widely used in station, harbour, bridge, hall, the installation of factory building indoor and outdoor machinery, maintenance of equipment, building maintenance etc. at present.The jacking system that the scissor-type job platform of manufacturer's manufacturing at present adopts hydraulic efficiency pressure system to drive; But it is high that the shortcoming of hydraulic efficiency pressure system is to use with cost of upkeep; There is leakage in fluid; Cause to adapt to some harsh working environment, use the lifting table that has hydraulic efficiency pressure system like some carnivorous processing enterprise even refusal.
Summary of the invention
The present invention provides a kind of Motorized lift device in order to satisfy more user's request, is used to replace hydraulic lift.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of Motorized lift device that is used for the scissor-type job platform; The Power Drive Unit that comprises scissor-type assembly and each the layer assembly open and close movement of control scissor-type assembly; Said scissor-type assembly comprises that the fork assembly is cut at the top, the fork assembly is cut at the middle part and the fork assembly is cut in the bottom; Said inner arm and outer arm and the yoke bearing pin of cutting the fork assembly is movably hinged, and two-layer up and down cutting pitched assembly and also be movably hinged with the yoke bearing pin, and said Power Drive Unit is an electric pushrod.
Further, said electric pushrod comprises power end and actuating station, and the inner arm connecting rod that the fork assembly is cut in said power end base and bottom is movably hinged, and the inner arm connecting rod that the fork assembly is cut at said actuating station top and middle part is movably hinged.
Further, said electric pushrod is installed in the middle part of scissor-type assembly inner arm connecting rod.
According to above technical scheme, can realize following beneficial effect:
The present invention is lifting power plant with the electric pushrod, effectively replaces hydraulic lift, has avoided the influence of the use leakage that hydraulic efficiency pressure system produced to complete machine and environment, thereby has further expanded the field of application of lifting table; Use the electric pushrod jacking system, the hydraulic ram, HM Hydraulic Motor, all kinds of hydraulic valve, oil pipe and the joint that are equipped with in the hydraulic efficiency pressure system need not be installed, only need the control power supply of junction circuit system to get final product; Simplified product structure greatly; Dwindle vehicle space, reduced dead weight of vehicle, saved the energy; Cost-cutting, also convenient simultaneously maintenance and maintenance; Electric pushrod has auto-lock function, and electrical motor stops operating, and actuating station rests on certain position immediately, and the height that makes platform remain on setting carries out aloft work; Electric pushrod can carry out stepless stroke adjustment according to customer requirements in specified travel range, thereby implementation platform arrives the purpose of differing heights.

The specific embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment involved in the present invention without limitation, below will combine accompanying drawing that technical scheme of the present invention at length is described.
Extremely shown in Figure 3 like Fig. 1; A kind of Motorized lift device that is used for the scissor-type job platform; The Power Drive Unit that comprises scissor-type assembly 1 and each the layer assembly open and close movement of control scissor-type assembly; Said scissor-type assembly 1 comprises that the top cuts that fork assembly 12 is cut at fork assembly 13, middle part and fork assembly 11 is cut in the bottom, and the said inner arm of cutting the fork assembly is movably hinged with outer arm and yoke bearing pin 14, and two-layer up and down cutting pitched assembly and also be movably hinged with yoke bearing pin 14; Said Power Drive Unit is an electric pushrod 2.The actuating station 22 of electric pushrod 2 can realize flexible under motor-driven.
Said electric pushrod 2 comprises power end 21 and actuating station 22, and the inner arm connecting rod 15 that fork assembly 11 is cut in power end 21 bases and bottom is movably hinged, and the inner arm connecting rod 15 that fork assembly 12 is cut at actuating station 22 tops and middle part is movably hinged.Said two inner arm connecting rods are parallel to each other.
Said electric pushrod 2 is installed in scissor-type assembly inner arm connecting rod 15 middle parts.
Shown in Figure 4 for the present invention is installed in the scheme drawing of scissor-type job platform, the bottom is cut fork assembly 11 and is connected with chassis assembly 4, and top movable assembly 13 is connected with platform assembly 4.
The up-down of platform assembly 4 is to lean on electric pushrod 2 that power is provided; Electric pushrod 2 comprises motor, retarder, base and actuating station; Behind the electrical power; Change speed and increase moment of torsion through retarder, base in-to-in leading screw is rotated, realize stretching thereby promote actuating station 22 outside or inside motions.Because the inner arm connecting rod 15 that fork assembly 11 is cut with the bottom respectively in the two ends of electric pushrod 2 is hinged with the inner arm connecting rod 15 that fork assembly 12 is cut at the middle part; Along with stretching of electric pushrod 2 actuating stations 22; The angle of scissor-type assembly 1 changes with highly producing accordingly; Under the support of chassis assembly 2, platform assembly 4 is realized.The scissor-type job platform higher for podium level, that load is bigger; Can or increase the scissor-type component count through lengthening scissor-type assembly yoke length and realize increasing operating altitude, can realize increasing working load through selecting big stroke, high-performance electric pushrod.
Electric pushrod has white lock function, and electrical motor stops operating, and actuating station rests on certain position immediately, and the height that makes platform remain on setting carries out aloft work; Electric pushrod can carry out stepless stroke adjustment according to customer requirements in specified travel range, thereby implementation platform arrives the purpose of differing heights; Electric pushrod adopts integrated full-closed structure, need not safeguard that volume is little, is convenient to installation and maintenance; Electric pushrod adopts gear and lead screw transmission, is active in one's movements, and operates steadily, and Stroke Control is accurate.The existing specialized factory of electric pushrod produces, and can directly buy needed model and specification.
Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the invention.
