Abstract
The utility model relates to a hinged rhombic multi-bar mechanism lifting device for the technical field of mechanism device, comprising a fixing platform, a lower hinged support, two sets of connecting rods, a lower roller, an upper roller, an upper hinged support, a moving platform, a hydraulic cylinder body, a piston rod, a primary, secondary, third pin shaft. And wherein, the fixing platform is horizontally fixed and the lower hinged support is fixed to the fixing platform; two sets of connecting rods are respectively hinged into two sets of hinged diamond multibar mechanism fixed through a set of pin shafts; the upper and lower ends of the hinged diamond multibar mechanism are respectively hinged with the upper hinged support and the lower hinged support and the upper hinged support is fixedly connected with the moving platform; the upper and lower rollers are respectively hinged at the ends of the upper and lower connecting rods of the hinged diamond multibar mechanism; the lower part of the hydraulic cylinder body is fixed to the pin shaft at the lowerest part and the upper part crosses the secondary pin shaft; the upper part of the piston rod is fixed to the third pin shaft. When lifting, the moving platform of the utility model makes a vertical motion without displacement phenomenon and the entire lifting device has a big lifting range and good stability.
Description
Technical field
The utility model relates to and be used for the mechanical device technical field, specifically is a kind of hinged rhombus multi-bar linkage formula jacking system.
Background technology
In work such as some Maintenance and Repair, storehouse management; using some jacking systems to satisfy the staff through regular meeting operates on the differing heights workplatform; present jacking system has much all adopted cuts posture mechanism; can realize the dipping and heaving of workplatform; but this dipping and heaving is not vertically; and also have offset movement, do not satisfy the motion requirement of workplatform vertical lifting sometimes.
Find that by retrieval China Patent No. is 99221068.2 utility model patent, patent name is: cut the posture garbage transfer station, this utility model uses non-positive pivotally attached to cut the posture hoisting rack as bont, drives parallel suspension bracket, makes the garbage container lifting.Finish maximum lifting height easily like this, but parallel suspension bracket can move in the plane of cutting the frame effect with cutting the frame center, make garbage container in lifting, have skew, this can make whole jacking system instability.
Summary of the invention
The utility model purpose is at deficiency of the prior art, and a kind of hinged rhombus multi-bar linkage formula jacking system is provided, and makes jacking system can not only satisfy the adjustable height requirement, and moving platform lifting vertically, no offset movement.
The utility model is achieved through the following technical solutions, and comprising: fixed platform, lower hinge support, two groups of connecting rods, bottom roller, upper roller, upper hinge support, moving platform, hydraulic cylinder body, piston rod, first, second, third bearing pin, its connection mode is: fixed platform horizontal fixed, lower hinge support are fixed on the fixed platform; Two groups of connecting rods are hinged to two groups of hinged rhombus multi-bar linkages respectively, and two groups of hinged rhombus multi-bar linkages are by first, second, third bearing pin captive joint; Two twices that boxed rod length is the rhombus-mechanism length of side of every group of hinged rhombus multi-bar linkage rhombus-mechanism bottom, bottom roller is hinged on the end of two boxed rods of lower end rhombus-mechanism respectively, every group of hinged rhombus multi-bar linkage lower end is hinged with lower hinge support respectively, itself and constitute moving sets with fixed platform, the center of bottom roller and lower hinge support center are on same horizontal surface; Every group of hinged rhombus multi-bar linkage rhombus-mechanism length of side topmost is half of other rhombus-mechanism length of side, its upper end is hinged with upper hinge support respectively, two upper hinge supports are captiveed joint with moving platform, upper roller is hinged on the end of connecting rod topmost, and constitute moving sets with moving platform, the center of upper roller and upper hinge support center are on same horizontal surface.The hydraulic cylinder body lower end is fixed on bottom on the bearing pin, and second bearing pin passed in the upper end, and the piston rod upper end is fixed on the 3rd bearing pin.
During the utility model work, hydraulic cylinder body is fixed, and drives hinged rhombus multi-bar linkage when piston rod stretches out, and hinged rhombus multi-bar linkage is moved straight up, and the moving platform level is risen; When piston rod bounced back, liquid drove hinged rhombus multi-bar linkage, made hinged rhombus multi-bar linkage along moving straight down, and the moving platform level is fallen.Hinged like this rhombus multi-bar linkage formula jacking system is realized the lifting to the moving platform level, and not skew.According to the difference of adjustable height, can suitably adjust the quantity of hinged rhombus.
Compared with prior art, be vertical motion during the moving platform lifting in the utility model, there is not shift phenomenon, particularly when the moving platform hanging object, can make moving platform more steady when loading.Whole jacking system lift is big, good stability, has good using value.
