The specific embodiment
To shown in Figure 6, the link-type guide plate driving mechanism of container spreader comprises linear oil cylinder 1, input bar 2, intermediate bar 3, guide plate structure 4 and base 5 such as Fig. 1.
The power of guide plate driving mechanism is provided by linear oil cylinder 1, and the hydraulic power of linear oil cylinder 1 comes from the hydraulic efficiency pressure system of suspender by oil pipe 14.
3,4 bottoms that shown guide plate structure 4 among the figure, the bottom of guide plate structure 4 comprises two parallel plates 10, linear oil cylinder 1, input bar 2, intermediate bar 3 are roughly between two parallel plates 40, and aftermentioned and the hinged of guide plate structure 4 or connection refer to hinged with this two parallel plate 40 or connect.
Hinged by axle 11 on the outer rod of linear oil cylinder 1 and the base 5, therefore cylinder body 15 can move, the first articulated section 201 of input bar 2 is hinged by axle 21 with cylinder body 15, the second articulated section 202 is hinged by axle 22 with base 5, the 3rd articulated section 203 is hinged with an end of intermediate bar 3 by axle 23, the other end of intermediate bar 3 is hinged by axle 34 and guide plate structure 4, and guide plate structure 4 is hinged by axle 45 with base 5.
Particularly, as shown in Figure 7, solid line is to turn over the position that reaches on the guide plate among Fig. 7, and dotted line represents to translate under the guide plate position that reaches.When linear oil cylinder 1 logical hydraulic oil is started working, the cylinder body upward sliding, simultaneously whole linear oil cylinder 1 can be around 11 slight swings of axle, and the motion of band moving axis 21 hinges promotes input bar 2 and rotates around axle 22, whole rotational angle is about 92 °, the rotation band moving axis 23 hinges motion of input bar 2 promotes intermediate bar 3 and moves, and intermediate bar 3 is by axle 34 hinges, drive guide plate structure 4 and rotate approximately 180 ° of whole rotational angles around axle 45.Arrive this, whole guide plate has been finished 180 ° upset work, has satisfied working condition requirement.
Continuation is referring to figs. 1 through Fig. 4, is provided with electromechanical stop 6 on the input bar 2, when turning on the guide plate to 0 ° (on turn over end position), turns over after electromechanical stop 6 restriction guide plates continue, and bottom girder or the overhanging beam structure of avoiding guide plate to knock suspender interfere.Be provided with on the pedestal 5 near limit switch 7, turn under the guide plate after 180 ° (the lower end positions that turn over), may with the outer side contacts of end carriage, understand feedback signals to electric-control system near limit switch 7 simultaneously, the reaction guide plate is in the down turning shape attitude, make oil cylinder carry out pressurize, the power thereby guide plate has certain effect plays directional tagging.Be welded with crashproof cone on the base 5, be conducive to protect whole mechanism not filled bad.
Although the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, in the situation that do not break away from variation or the replacement that spirit of the present invention also can be made various equivalences, therefore, as long as in connotation scope of the present invention in the scope to the variation of above-described embodiment, claims that modification all will drop on the application.
