The purpose is to provide a monolithic lateral displacement distance adjusting fork with narrow front suspending distance, great carrying capacity and relatively simple structure. The technical proposal comprises: a horizontal beam of the fork has a structure with two hollow ends; each hollow cavity at the two ends is provided with a lateral displacement fuel tank, wherein, the ends of a plunger pole of the lateral displacement fuel tank respectively retain the internal side of the vertical arms at the two sides of a door frame type external fork frame; chain wheels are respectively arranged at the internal sides of the top ends of the vertical arms; chains are wound between the two chain wheels; a polished rod shaft is arranged horizontally on the vertical arm below the chain and above the beam on the door frame type external fork frame; the shaft is sheathed with a left return board and a right return board, wherein, the right return board is connected with the chain at one side of the two chain wheels, the top end of the return board is connected with the front part of the distance adjusting fuel tank with the rear end fixed in the top end of the vertical arm at the right side; the left return board is connected with the other end of the chain wheel wound by the chain, thus forming a closed-loop structure.

Description

Integral side displacement range regulation roll adjustment fork

Technical field

The utility model relates to the special-purpose accessory of a kind of fork truck, thereby particularly by hydraulic-driven the pallet fork integral left is moved right and regulate the integral side displacement range regulation roll adjustment fork that distance makes things convenient for the goods fork to get and stack between pallet fork and the pallet fork.

Background technology

Chinese patent 200620068433.1 discloses a kind of integral side displacement range regulation fork of large tonnage fork lift, in this integral side displacement range regulation roll adjustment fork comprises goods shelf before goods shelf and two pallet forks, preceding goods shelf is for falling a door shape, its middle part level is provided with pallet fork load-bearing axle, and two pallet fork tops are socketed in respectively on the pallet fork load-bearing axle.The rear portion of goods shelf before interior goods shelf vertically is positioned at, interior goods shelf upper level welding axle sleeve, plug-in mounting load-bearing axle in the axle sleeve, load-bearing axle two ends are fixedly connected on respectively on the both sides upright arm of preceding goods shelf, load-bearing axle parallel beneath is provided with the sidesway oil cylinder, the upright arm of goods shelf one side before the head sections of sidesway oil cylinder connects, the afterbody end connecting bushing outside.Goods shelf before the sidesway oil cylinder promotes by moving load-bearing axle and cooperating of axle sleeve, can be realized sliding with respect to the left and right sidesway of interior goods shelf.The upright arm inboard, both sides of preceding goods shelf connects the afterbody of a roll adjustment oil cylinder respectively, the head end of left side roll adjustment oil cylinder is connected with right fork, the head of right side roll adjustment oil cylinder is connected with left pallet fork, and left and right roll adjustment oil cylinder can promote the roll adjustment function that left and right pallet fork is inwardly realized simultaneously, outwards slided on the load-bearing axle.Front overhang is little though this integral side displacement range regulation roll adjustment fork has, and load-carrying capacity is big, and the advantage of compact conformation etc., its structure are comparatively complicated.

Summary of the invention

The purpose of this utility model provides that a kind of front overhang is little, and load-carrying capacity is big, the comparatively simple integral side displacement range regulation roll adjustment fork of structure.

Its technical scheme is: a kind of integral side displacement range regulation roll adjustment fork comprises interior crotch, outer crotch and two the fixedly slide plate and the bidirectional relief valve piece of pallet fork.It is characterized in that: interior crotch is made of riser column, riser and the welding of upper and lower crossbeam, be connected by riser between entablatrance and the cross sill, upper and lower crossbeam and riser and riser column are connected and fixed, entablatrance is the planform of two hollow, in the cavity at its two respectively correspondence a sidesway oil cylinder is set, the plunger rod head end of sidesway oil cylinder connects with the upright arm inboard, both sides of the outer crotch of frame-type respectively; The inboard, upper end of the outer crotch both sides of frame-type upright arm, be separately installed with sprocket wheel, be wound with chain between two sprocket wheels, on the both sides upright arm on chain below and the outer crotch entablatrance, be horizontally installed with the polished rod axle as slide rail, be set with left and right two slide plates on the polished rod axle; Right slide plate is connected with the chain of sprocket wheel one side, and its top is connected with the head of roll adjustment oil cylinder in afterbody is fixed on outer crotch left vertical arm top, and left skateboard is connected with the chain of sprocket wheel opposite side, forms a closed-loop structure that is connected in series.

Its technique effect is: the utility model is owing to utilize the entablatrance of interior goods shelf, dexterously two sidesway oil cylinders are installed in this entablatrance, and on the upper and lower crossbeam of interior goods shelf crotch outside the coupling stack frame-type, make it to integrate into as a whole, so under hydraulically powered effect, can promoting the outer crotch of frame-type, the sidesway oil cylinder realizes moving with respect to the left and right side of interior goods shelf.Simultaneously, adopting single roll adjustment hydraulic oil cylinder driving to promote right slide plate moves, it is guide rail with the polished rod axle that transmission by series connection sprocket wheel of closed loop and chain can drive the left and right pallet fork that is fixed on the left and right slide plate, realize simultaneously inside or outside slip and the speed unanimity, also just realized regulating the distance between pallet fork and the pallet fork.Therefore, this integral side displacement range regulation roll adjustment fork front overhang is little, and load-carrying capacity is big, and its structure is comparatively reasonable, complete, compact and simple, makes the load-carrying capacity of fork truck obtain further optimization; Its stability, synchronism and fastness are better.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, integral side displacement range regulation roll adjustment fork comprises the fixedly slide plate of pallet fork of interior crotch, outer crotch and two.Interior goods shelf is connected and composed by riser column, riser and upper and lower crossbeam.Be connected by riser 9 between entablatrance 13 and the cross sill 8, and with two riser columns, 15 vertical being connected and fixed.Entablatrance is the planform of two hollow, in the cavity at its two respectively correspondence a sidesway oil cylinder 12 is set, the plunger rod head of sidesway oil cylinder connects with both sides upright arm 11 inboards of the outer crotch of frame-type respectively.

The inboard, upper end of the outer crotch both sides of frame-type upright arm 11, be separately installed with two sprocket wheels 5, be wound with chain 3 between two sprocket wheels, be horizontally installed with between the outer crotch entablatrance of chain below and frame-type polished rod axle 16 as slide rail and with the both sides upright arm of the outer crotch of frame, be set with left and right two
