Detailed description of the invention
In the present embodiment, the structure of vertical lift device is set to:
As depicted in figs. 1 and 2, one parallelogram transmission device is set, comprise: on two side roof part frame 1a respectively hinged the first rocking bar 4a and the second rocking bar 4b, between the first rocking bar 4a and the second rocking bar 4b, connect with pull bar 7, the outside rod end of the first rocking bar 4a and the second rocking bar 4b is respectively arranged with the first slide block 6a and the second slide block 6b that are on sustained height, the first slide block 6a and the second slide block 6b are with horizontal lifting framework 5 for sliding pair is connected, and load 14 is placed on horizontal lifting framework 5;
As shown in figures 1 and 3, be provided as the quadric linkage of driver train, comprise: one end of connecting rod 3 is with to be arranged on crank 2 on crank frame 1c hinged, one end hinged formation drive end hinge-point 16 of the other end of connecting rod 3 and pull bar 7;
As shown in Figure 1 and Figure 4, vertical lift furcated mechanism is set, comprises: hinged to pitch gear one end of strut 11 and one end of horizontal lifting framework 5, form vertical lift hinge-point 15, the other end and the horizontal sliding bar 9 of fork gear strut 11 are hinged; Be hinged on the middle part of fork gear strut 11 with one end of fork connecting rod 10, the other end of fork connecting rod 10 is hinged on the bar linkage frame 1b of the below that is positioned at vertical lift hinge-point 15.
As shown in Figure 1 and Figure 5, the steady unit of deadweight being made up of hydraulic actuating cylinder 8 is set in the present embodiment, the rod end of hydraulic actuating cylinder 8 and drive end hinge-point 16 are hinged, and it is upper that the cylinder seat of hydraulic actuating cylinder 8 is hinged on hydraulic actuating cylinder frame 1d, and hydraulic actuating cylinder 8 is connected with water bumper 13 by liquid road 12.
Operating principle:
Crank 2 is done the contiguous circumferential motion around frame 1c under driving, move by hinged drivening rod 3, connecting rod 3 is done circumference oscillating traverse motion by hinged drive the first rocking bar 4a around top frame 1a, the first rocking bar 4a and the second rocking bar 4b drive the lifting of horizontal lifting framework 5 around the circumference reciprocally swinging of frame top frame 1a, but because the path of motion of the first rocking bar 4a and the second rocking bar 4b is circumference reciprocally swinging, therefore, itself can not make horizontal lifting framework 5 keep horizontality and vertical lift.
Horizontal lifting framework 5 and the first slide block 6a and the second slide block 6b composition sliding pair, therefore horizontal lifting framework 5 can be under the effect of sliding pair, horizontal slip in the first slide block 6a and the second slide block 6b; Adopt pull bar 7 that connecting rod 3, the first rocking bar 4a and the second rocking bar 4b are articulated and connected simultaneously, realize the synchronous swing of the first rocking bar 4a and the second rocking bar 4b; Under the pulling of connecting rod 3, the first rocking bar 4a and the second rocking bar 4b force horizontal lifting framework 5 to keep horizontality lifting.This version has ensured the horizontal lifting of horizontal lifting framework 5.
For realizing the vertical lift of horizontal lifting framework 5, make the hinged composition of itself and vertical lift fork strut 11 be positioned at the revolute pair on 15 of vertical lift hinge-points.Vertical lift fork strut 11 is hinged with slide bar 9, simultaneously in order to make dipping and heaving become controlled horizontal motion, vertical lift fork connecting rod 10 carries out hinged at the mid point of vertical lift fork strut 11, the length that vertical lift fork connecting rod 10 is set is 1/2nd of vertical lift fork strut 11.The isoceles triangle fork-shaped lifting mechanism forming is coupled controlled horizontal motion and uncontrollable dipping and heaving, has realized the vertical lift track of vertical lift hinge-point 15.
Consider the ability of high capacity under the steady and identical power-handling capability of lifting.The present embodiment arranges interior circulation hydraulic balance device on drive end hinge-point 16, and with the deadweight of the power output balance lifting part of hydraulic actuating cylinder 8, the power resources of hydraulic actuating cylinder 8 are in water bumper 13.The size of the internal pressure of water bumper 13 derives from the deadweight of lifting mechanism, realizes the automatic balance function of lifting structure, reaches stationarity when high load capability is with raising lifting under identical power-handling capability.
