Description
Technical field
The utility model relates to a kind of electric pallet truck pallet fork head guide wheel device, mainly is applicable in electric pallet truck.
Background technology
Traditional electric pallet truck generally is mainly used in shoveling the open type pallet, is rarely used in shovel enclosed pallet, has caused its range of use limited.When shovel enclosed pallet, all that front-wheel directly contacts with pallet entering when withdrawing from pallet, there is following drawback in this mode: 1, different manufacturers pallet used is different, some tray bottom plate hights, some tray substrates are low, for the high pallet of base plate, the pallet fork head of general transport trolley be not easy by, make the tray truck field of application limited.2, when tray truck shovel pallet, the general method of using of workman is by acceleration, makes front-wheel enter fast pallet by velocity inertial, the operative technique that such action need is skilled, and have certain potential safety hazard.Although 3 for most pallet, the pallet electrocar can pass through easily, and is of long duration because front-wheel often contacts with pallet, can accelerate the wearing and tearing of front-wheel; Adopt the transport trolley of the board-like pallet fork head of guiding more serious to the damage of pallet, use cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for above-mentioned existence provides a kind of electric pallet truck pallet fork head guide wheel device simple in structure, with the field of application that enlarges tray carriage, increase work efficiency and safety factor, reduce simultaneously maintenance cost.
The technical scheme that the utility model adopts is: electric pallet truck pallet fork head guide wheel device, and it is characterized in that: it comprises the permanent seat that is connected for tray carriage, and the roller set that is articulated in this permanent seat lower surface, also can freely rotates; The roller set little front-wheel and the little trailing wheel that comprise two parallel and adapter plates of being arranged symmetrically with, be installed between two adapter plates and can freely rotate around himself axis wherein, respectively being shaped with one outside two adapter plates is used for and the hinged bearing pin to realize that roller set is freely rotated of permanent seat, the axis of described little front-wheel and little trailing wheel is all perpendicular to adapter plate and lay respectively at the both sides of bearing pin place axis, and under state of nature, the center of gravity of little trailing wheel is lower than the center of gravity of little front-wheel.
Described permanent seat upper surface is provided be used to the adjusting pad of adjusting whole track adjusting wheel height.
Described adapter plate is shaped with two spacing preiections near one on the limit of permanent seat one side, and two spacing preiections lay respectively at the two ends on this limit.
Described little front-wheel and little trailing wheel all adopt bolt nut structure to be articulated between two adapter plates.
The beneficial effects of the utility model are: the utility model is hinged with the roller set that can freely rotate on permanent seat, and the little front-wheel in this roller set and little trailing wheel can freely rotate around himself axis; The utility model is installed on tray carriage pallet fork head, the roller set that utilization can freely be rotated around hinge-point, the tray carriage front-wheel is mentioned certain altitude, can adapt to the pallet of multiple differing heights during the scraper pallet, not only enlarged the field of application of tray carriage, and avoided entering by acceleration the problem that pallet causes potential safety hazard and pallet well damage in the prior art, improved work efficiency; Reduced simultaneously the friction of front-wheel and pallet, when abrasion is serious, has changed little front-wheel and little trailing wheel and get final product, thereby reduced maintenance cost.

The specific embodiment
As shown in Figure 1-Figure 3, the present embodiment comprises and offers at least three tapped bore on this permanent seat for the permanent seat 1 that is connected with tray carriage, is used for realizing being connected with the tray carriage pallet fork; One is shaped with two with the axle bed 1-1 of through hole on the lower surface of permanent seat 1 simultaneously, and two axle bed 1-1 are all perpendicular to permanent seat 1 lower surface, and the through hole coaxial arrangement of two axle bed 1-1; Be hinged with the roller set 2 that freely to rotate around its through-bore axis on described axle bed 1-1.
described roller set 2 comprises two parallel and be arranged symmetrically with adapter plate 2-1, and is installed on little front-wheel 2-2 and little trailing wheel 2-3 between two adapter plate 2-1, its medium and small front-wheel 2-2 and little trailing wheel 2-3 all are articulated between two adapter plate 2-1 by bolt 4 and nut 5, after installation, two adapter plate 2-1, little front-wheel 2-2 and little trailing wheel 2-3 form an integral type roller set, little front-wheel 2-2 and little trailing wheel 2-3 all can freely rotate around himself axis, both axis are all perpendicular to adapter plate 2-1 simultaneously, and lay respectively at the both sides of axle bed 1-1 through-bore axis, under state of nature the center of gravity of little trailing wheel 2-3 lower than the center of gravity of little front-wheel 2-2 (little trailing wheel center to the vertical distance of through-bore axis greater than the little front-wheel center vertical distance to through-bore axis, and little front-wheel and little trailing wheel are identical in quality), respectively be shaped with a bearing pin 2-4 who is complementary with described axle bed through hole outside two adapter plate 2-1, form whole roller set 2 and be articulated on axle bed 1-1 by two bearing pin 2-4, two adapter plate 2-1, little front-wheel 2-2 and little trailing wheel 2-3 all can freely rotate around bearing pin 2-4 axis.
Described adapter plate 2-1 is shaped with two spacing preiection 2-5 near one on the limit of permanent seat 1 one sides, and two spacing preiection 2-5 lay respectively at the two ends on this limit.
Described permanent seat 1 upper surface is provided with adjusting pad 3, can adjust according to actual conditions the height of whole track adjusting wheel, to adapt to the pallet of differing heights; Offer simultaneously one group of through hole corresponding with permanent seat 1 upper screwed hole on adjusting pad 3.
As shown in Figure 4, in actual the use, this routine track adjusting wheel is installed on the head of tray carriage pallet fork, and guarantees little front-wheel 2-2 nadir higher than the upper surface of tray substrate 6, and the nadir of little trailing wheel 2-3 is lower than the upper surface of tray substrate 6; Under the scraper initial condition, tray substrate 6 only contacts with little trailing wheel 2-3, if tray carriage moves on, tray substrate 6 can apply an opposition to little trailing wheel 2-3, forces little front-wheel 2-2 and little trailing wheel 2-3 to rotate around bearing pin 2-4 axis, regulates the height of two steamboats (little front-wheel and little trailing wheel), little front-wheel 2-2 is descended, little trailing wheel 2-3 raises, thereby reduces the diff-H between little trailing wheel 2-3 and tray substrate 6, and this moment, little trailing wheel 2-3 can roll on tray substrate 6 easily; After little front-wheel 2-2 and little trailing wheel 2-3 are rolled on tray substrate 6, the head of tray carriage pallet fork just has been elevated, make tray carriage front-wheel 7 can be more prone to by tray substrate 6, thereby improved work efficiency, and reduced the friction of tray carriage front-wheel 7 with tray substrate 6; When little front-wheel 2-2 or little trailing wheel 2-3 serious wear, replaceable two steamboats, easy to maintenance, convenient, and cost is low.
