A kind of fork hydraulic lifting electric flatcar
Technical field:
The utility model relates to a kind of electric flat carriage, particularly a kind of fork hydraulic lifting electric flatcar.
Background technology:
The lifting mechanism of existing lifting electric flatcar directly arranges hydraulic actuating cylinder under the table top of electric flat carriage, drives table top lifting by hydraulic cylinder piston rod is flexible.Because hydraulic actuating cylinder and table top are that point is stressed, make the less stable of table top, especially when table top unbalance loading, easily cause hydraulic actuating cylinder to damage, even fracture piston rod; The second lifting mechanism adopts fork hydraulic lifting mechanism that table top be elevated, and this lifting mechanism overcomes the defect of the first structure, but for time too low to table top requirement, space constraint installation hydraulic actuating cylinder and cannot implementing.
Summary of the invention:
The utility model object be to provide a kind of table top steadily and table top requirement can be made too low when a kind of fork hydraulic lifting electric flatcar that can be elevated.
The technical scheme realizing the utility model object is, a kind of fork hydraulic lifting electric flatcar, comprise electric flat carriage car body and table top, it is characterized in that: between described battery-driven car car body and table top, be provided with crotch, in described crotch intersects by two, crotch and outer crotch form, in described, the middle part of outer crotch is provided with and turns the hole of joining mutually with bearing pin, otic placode on its upper end of crotch, China and foreign countries and described table top lower surface is hinged, the lower end of this crotch is provided with roller, on this roller and described battery-driven car car body, the up and down slideway of horizontally set is slippery, the upper end of interior crotch is provided with roller, on this roller and table top, the up and down slideway of horizontally set is slippery, otic placode in this on lower end of crotch and battery-driven car car body is hinged, between described battery-driven car car body and table top, be provided with two hydraulic actuating cylinders symmetrically, Hydraulic Station is located on battery-driven car car body.
The utility model has the remarkable advantage making table top stable elevation under the condition that table top requirement is too low compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is the front view of the utility model fork hydraulic lifting electric flatcar; Fig. 2 is the left view of Fig. 1.
Detailed description of the invention:
The utility model has following embodiment, as Fig. 1, shown in 2, a crotch is provided with between electric flat carriage car body 8 and table top 1, in described crotch intersects by two, crotch 4 and outer crotch 3 form, in this, outer crotch forms by two yokes, in these two, the middle part of outer crotch is provided with the hole with bearing pin normal-running fit, otic placode on the upper end of two yokes of its China and foreign countries' crotch and table top lower surface is hinged, the lower end of this yoke is equipped with a roller 5 and respectively with on electric flat carriage body, the lower sideslipway 7 closed is slippery, the upper end of two yokes of described interior crotch is equipped with roller and slippery with the up and down slideway 6 of horizontally set on table top lower surface respectively, the lower end of these two yokes is hinged with electric flat carriage car body respectively, two hydraulic actuating cylinders 2 are located between electric flat carriage car body and table top symmetrically, Hydraulic Station 9 is located on electric flat carriage car body, the bottom of electric flat carriage car body is provided with wheel 10 and matches with track 11.
The principle of the utility model table top lifting, when the piston rod of two hydraulic actuating cylinders stretches out, table top rises, and crotch 4 upper end roller moves to left in the slideway on table top lower surface, and meanwhile, the roller of crotch 3 lower end moves to left to the slideway on battery-driven car car body upper surface; When hydraulic cylinder piston rod shrinks, the roller of two crotch right-hand members moves to right respectively in respective slideway.The hydraulic oil of two hydraulic actuating cylinders is supplied by the Hydraulic Station be located on battery-driven car car body.
