Description of drawings
Figure 1 shows that the prong decomposition texture scheme drawing of roller pallet fork of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the prong of first embodiment of the invention roller pallet fork, comprise the tip of the tongue 1 and the hyoplastron 2 in order to lift goods of captiveing joint with roller pallet fork matrix, described the tip of the tongue center is formed with to hold the curvature of the opening of hyoplastron and hyoplastron leading section greater than the tip of the tongue end curvature, the open interior of the described the tip of the tongue is formed with pivot shaft, be formed with more backward larger variable curvature groove 6 of curvature with the pivot shaft corresponding position on the described hyoplastron, described hyoplastron rear end with can the relative the tip of the tongue can before and after the connecting panel 3 that slides hinged.
Specifically, both sides, the described the tip of the tongue 1 rear end shape has mounting groove 8, and the tip of the tongue is fixed on the roller pallet fork matrix by bolt and the mounting blocks 9 that runs through the tip of the tongue bolt hole 12.Described the tip of the tongue front end is formed with rectangular aperture to hold hyoplastron, described opening inner side edge inwardly is formed with two pivot shafts 7 highlightedly simultaneously, be provided with bearing 4 at described pivot shaft cover, described bearing is preferably needle bearing, described variable curvature groove and described bearing are formed on hyoplastron lower surface both sides accordingly, be that variable curvature concave surface and this variable curvature concave surface and needle bearing are set on the hyoplastron is tangent, the degree of freedom that simultaneously the hyoplastron maintenance is moved forward and backward and overturns, the variable curvature concave surface of hyoplastron can be along the needle bearing surface sliding like this, can realize the perk of hyoplastron front end or fall when sliding.
Be seesawing of restriction hyoplastron, both sides, described hyoplastron rear end are formed with mounting hole, described connecting panel 3 front end inboards are formed with the rotating shaft with described mounting hole coupling, offer simultaneously connecting panel is spacing in it and the sliding tray that can allow connecting panel to move forward and backward at the tip of the tongue.For keeping hyoplastron not perk under off working state, between described connecting panel rear end and sliding tray inner end surface, be provided with the spring 5 that connecting panel is outwards ejected, wherein, for avoiding spring that connecting panel is ejected sliding tray, described sliding tray is T slot, simultaneously be formed with projection in described connecting panel rear end, and be provided with in open front place of sliding tray and captive joint with the described the tip of the tongue and can prevent the locating plate 10 that projection is deviate from from sliding tray.Simultaneously T slot has also strengthened the effect of location, guiding.
When the roller pallet fork pitch pretend the industry, when prong initially contacts with goods, because the end curvature of hyoplastron 2 is greater than the end curvature of the tip of the tongue 1, therefore hyoplastron 2 contacts with goods prior to the tip of the tongue 1, drive together Compress Spring 5 generation displacements backward of connecting pin 3 after hyoplastron 2 carryings, because the variable curvature concave surface 6 on the hyoplastron 2 is tangent with needle bearing 4 all the time, and less the closer to front end curvature, therefore when the hyoplastron 2 relative thes tip of the tongue are the certain displacement of pallet fork matrix direction generation to the back-end, the free end of hyoplastron 2 just can be lifted certain height under the effect of needle bearing, so goods is just lifted certain height automatically, thereby so that the fork that advances of roller pallet fork becomes very simple.When goods " was drawn " the upper fork matrix by the roller set of roller pallet fork, the hyoplastron free end separated no longer carrying with goods, return to initial condition under the effect of spring 5.
The second embodiment
Distortion as above-described embodiment, also the relative opening of described pivot shaft both sides can be connected and arrange, be to be provided with pivot shaft between described opening dual-side, be provided with bearing between described pivot shaft two ends and the tip of the tongue, described variable curvature groove and pivot shaft are formed on the hyoplastron lower surface accordingly, can give like this hyoplastron lower faceplate linear support, improve support effect.Other structures and the first embodiment are similar, no longer launch to describe at this.
The 3rd embodiment
The basic structure of present embodiment and the first embodiment is similar, its difference is in and inwardly is formed with highlightedly variable curvature cambered surface sled platform in the opening both sides of the described the tip of the tongue, be formed with accordingly roller in described hyoplastron bottom with described sled platform, namely change the installation site that can force hyoplastron perk structure, although its set-up mode has more different with the first embodiment, but belong to an inventive concept, those skilled in the art can realize this embodiment on the basis of the first embodiment, so do not repeat them here.
Certainly, for above-mentioned three embodiment, what adopt with the pivot shaft effect is variable curvature groove or cambered surface sled platform, adopts corresponding ramp type groove or wedge shape sled platform can realize aim of the present invention equally, does not repeat them here.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
