Abstract
The invention relates to the technical field of lifting mechanisms, in particular to a lifting mechanism. The lifting mechanism comprises a hydraulic cylinder, a bedplate, driving shafts and a rack. The movable end of the hydraulic cylinder stretches into the rack, a bevel cam is arranged at the front end of the output end of the hydraulic cylinder, the driving shafts are vertically arranged on the rack, the top ends of the driving shafts are connected with the bedplate horizontally arranged above the rack, the bottom end of one driving shaft extends to the bevel cam, and a rolling wheel is further arranged at the bottom end of the driving shaft and matched with the bevel cam. Driving force is small, lifting force is large, and ascending and descending are stable.
Description
Technical field
The present invention relates to lifting mechanism technical field, be specifically related to a kind of lifting mechanism.
Background technology
Realizing mainly with cylinder or hydraulic actuating cylinder of existing lifting mechanism, but the propulsive effort that exports of cylinder or hydraulic actuating cylinder is limited at present, and the propulsive effort of output and the specified output of self necessarily, have very large restricted in use.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned defect, and provide a kind of lifting mechanism, propulsive effort is little, and hoisting force is large, and lifting steadily.
The technical scheme that the present invention solves the employing of its technical matters is as follows:
A kind of lifting mechanism, comprise hydraulic actuating cylinder, platen, axle drive shaft, frame, described hydraulic actuating cylinder movable end probes into machine frame inside, hydraulic actuating cylinder mouth front end is provided with surface cam, described axle drive shaft is vertically arranged in frame, axle drive shaft top connects the platen be horizontally set on above frame, axle drive shaft bottom extends to surface cam place, and axle drive shaft bottom is also provided with the roller coordinated with surface cam, hydraulic cylinder piston rod moves forward, the inclined-plane of surface cam is contacted with bottom axle drive shaft, push axle drive shaft to move up and down, platen is made to realize oscilaltion, the inclined-plane of cam will be given birth to lifting force and be amplified, improve the carrying of bedplate up-down, roller coordinates with surface cam and prevents axle drive shaft from wearing and tearing, avoid and surface cam self-locking.
Further, described axle drive shaft is connected with frame with permanent seat, axle drive shaft and permanent seat bearing fit.
Further, also be provided with the pilot bar of guide support between described frame and platen, pilot bar is fixed in frame with permanent seat, pilot bar and permanent seat sliding block joint, pilot bar rise when bedplate up-down is pushed to axle drive shaft guiding and support, positioning action, make bedplate up-down steady.
The invention has the beneficial effects as follows: adopt such scheme, surface cam pushes axle drive shaft and makes platen oscilaltion, the horizontal drive of hydraulic actuating cylinder is amplified the oscilaltion converting platen to through surface cam, improve the bearing capacity of bedplate up-down, increase usability.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is structural representation of the present invention.
Wherein: 1 is hydraulic actuating cylinder, 2 is platen, and 3 is axle drive shaft, and 3.1 is permanent seat, and 4 is frame, and 5 is surface cam, and 6 is pilot bar, and 7 is roller.
Detailed description of the invention
A kind of lifting mechanism as shown in Figure 1, comprise hydraulic actuating cylinder 1, platen 2, axle drive shaft 3, frame 4, it is inner that hydraulic actuating cylinder 1 movable end probes into frame 4, hydraulic actuating cylinder 1 mouth front end is provided with surface cam 5, axle drive shaft 3 is vertically arranged in frame with fixed mount 3.1, axle drive shaft 3 and permanent seat 3.1 bearing fit, axle drive shaft 3 top connects the platen 2 be horizontally set on above frame 4, axle drive shaft 3 bottom extends to surface cam 5 place, and axle drive shaft 3 bottom is also provided with the roller 7 coordinated with surface cam 5, the pilot bar 6 of guide support is also provided with between frame 4 and platen 2, pilot bar 6 is fixed in frame 4 with permanent seat 3.1, pilot bar 6 and permanent seat 3.1 sliding block joint.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
