The specific embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation, explains the technical solution of the utility model below with reference to accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of Motorized lift device 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, described scissor-type assembly 1 comprises that fork assembly 13 is cut at the top, fork assembly 12 is cut at the middle part and fork assembly 11 is cut in the bottom, describedly cut the fork inner arm of assembly and outer arm is movably hinged with yoke bearing pin 14, two-layer cutting pitched assembly and also is movably hinged with yoke bearing pin 14 up and down; Described Power Drive Unit is electric pushrod 2.The actuating station 22 of electric pushrod 2 can realize flexible under motor-driven.
Described 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.Described two inner arm connecting rods are parallel to each other.
Described electric pushrod 2 is installed in scissor-type assembly inner arm connecting rod 15 middle parts.
Figure 4 shows that the utility model is installed in the schematic diagram 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 lifting of platform assembly 4 is to provide power by electric pushrod 2, electric pushrod 2 comprises motor, retarder, base and actuating station, behind the electrical power, change speed and increase moment of torsion by retarder, the leading screw of base inside is rotated, realize stretching thereby promote actuating station 22 outside or inside motions.Because the inner arm connecting rod 15 of fork assembly 11 is cut with the bottom respectively in the two ends of electric pushrod 2 and inner arm connecting rod 15 that fork assembly 12 is cut at the middle part is hinged, along with stretching of electric pushrod 2 actuating stations 22, the angle of scissor-type assembly 1 and the highly corresponding variation of generation, under the support of chassis assembly 2, platform assembly 4 is realized lifting.The scissor-type job platform higher for podium level, that load is larger, can realize increasing operating altitude by lengthening scissor-type assembly yoke length or increasing the scissor-type component count, can realize increasing working load by selecting large stroke, high-performance electric pushrod.
