The fork of tumbling

Technical field

The utility model relates to a kind of fork of tumbling, and is mainly used in the goods on the pallet fork is toppled over, as strip goods, bag cargo; The configuration scraper bowl can shovel the various loose goods of fortune, as: sand, coal, cereal, fertilizer, soil block and queen closer etc.

Background technology

At present, great majority are tumbled on the market, and lose to carry square big for fork, and the accessory deadweight is bigger, has reduced the combination load-carrying capacity of fork truck to a great extent; In addition, adopt single dump ram structure, and place it in the middle, cause forklift operator personnel sight line partly to be blocked, be inconvenient to operate, and poor stability when adopting the work of single oil cylinder, unbalance stress causes dump cradle easily and the crotch plate hinged place of tumbling is damaged; In addition, generally all join nonstandard pallet fork, commonality is not high, brings inconvenience to the user.

Summary of the invention

The technical problems to be solved in the utility model is: at the problem of above-mentioned existence provide a kind of simple in structure, lose carry apart from little, from heavy and light, the operation visual field is broad, commonality the is high fork of tumbling, improve each parts stressing conditions simultaneously, stability during raising work increases the service life.

The technical scheme that the utility model adopted is: the fork of tumbling, have the bearing pin of the employing pivotally attached dump cradle and the crotch plate of tumbling, and be used to control the dump ram of crotch plate of tumbling around bearing pin axis swing, wherein the dump ram two ends are hinged with the dump cradle and the crotch plate of tumbling respectively, the retaining shelf are installed at the dump cradle top, tumbling mounts pallet fork on the crotch plate, and it is characterized in that: described dump ram has two, and two ends, the dump cradle left and right sides are placed in.

The described crotch plate of tumbling comprises rectangle crotch plate body and two swing arms of captive joint and symmetric arrangement with it, and this swing arm one end is hinged by described bearing pin and described dump cradle, and the other end and described dump ram are hinged.

Described spacing of tumbling between the crotch plate lower and upper cross-member satisfies the III grade standard installs, and corresponding pallet fork is a standard III level pallet fork.

Described dump ram is an oscillating bearing with the crotch plate coupling end of tumbling.

Described bearing pin comprises axle core of captiveing joint with dump cradle and the axle sleeve of captiveing joint with the crotch plate of tumbling, rotating coaxial being embedded in the axle sleeve of its axis core, and stretch out at two ends.

Described axle core one end stretches out on the axle sleeve periphery partly offers cannelure, and close-fitting is installed the rectangle stay in this groove, and dump cradle is pressed in this stay side.

Described axle sleeve adopts the self-lubricating powder metallurgy sleeve.

Described axle in-core is put lubricating cup.

Described retaining shelf adopt the welding of 6# hot-rolled steel channel to form.

The beneficial effects of the utility model are: the utility model adopts two dump ram structures, and splits both sides, has not only widened the operation visual field greatly, and has improved the stressing conditions of each parts, makes more reasonable stress, thereby has improved the stability when accessory is worked; The spacing of tumbling between the crotch plate lower and upper cross-member satisfies the installation of III grade standard, and pallet fork is a standard III level pallet fork, the commonality height, and convenient client uses; The axle sleeve of bearing pin adopts the self-lubricating powder metallurgy sleeve, offer cannelure on the axle core, and close-fitting is installed the stay that a side is pressed dump cradle in groove, utilize friction force between stay and the dump cradle to realize captiveing joint of axle core and dump cradle, when bearing pin is stuck, stay is by wear down, and the relative dump cradle of axle core is rotatable, thereby has prolonged service life greatly; The retaining shelf adopt the channel-section steel welding to form, and have alleviated the accessory deadweight in the time of proof strength; The utility model patent structure compactness is lost and is carried apart from little in addition, and easy accessibility is easy to make and safeguard.

The specific embodiment

As shown in Figure 1-Figure 3, present embodiment comprises dump cradle 1, the one upper lateral part 11 is mounted on the crotch body 12 by rising to the bait, the bottom then utilizes sliding block 8 and bolt to position, rise to the bait 11 and sliding block 8 mutual actions under, dump cradle 1 is fixed on the crotch body 12, sliding block 8 adopts oblique waist-shaped hole design in this example, as shown in Figure 9, easier for installation, and the commonality height; Described dump cradle 1 opposite side is by the bearing pin 4 hinged crotch plates 2 of tumbling, tumble and hingedly on the crotch plate 2 be used to control its dump ram 10 around bearing pin 4 swings, this dump ram other end is then hinged with dump cradle 1, in this example, dump ram 10 has two, vertically is arranged in two ends, dump cradle 1 left and right sides respectively, not only widened the operation visual field the when staff operates greatly, and improved the stressing conditions of each parts, and make more reasonable stress, thus the stability when having improved accessory work; Retaining shelf 3 are installed by bolt in described dump cradle 1 top, and these retaining shelf adopt the common channel-section steel welding of 6# hot rolling as shown in Figure 8 to form, and intensity can be effectively guaranteed, and simple in structure, and cost is low, and accessory is from heavy and light; Tumbling mounts pallet fork 9 on the crotch plate 2, and the spacing between crotch plate 2 lower and upper cross-members of tumbling described in this example satisfies the III grade standard installs, and corresponding pallet fork 9 is a standard III level pallet fork, the commonality height, the convenient use simultaneously in order to prevent pallet fork 9 horizontal landings, installed baffle plate at the entablatrance two ends by screw.

As shown in Figure 4, the described crotch plate 2 of tumbling comprises rectangle crotch plate body 2-1 and two swing arm 2-2 of captive joint and symmetric arrangement with it, and each swing arm one end is hinged with described dump cradle 1 by described bearing pin 4, and the other end and described dump ram 10 are hinged.As shown in Figure 5, described dump ram 10 is an oscillating bearing with crotch plate 2 coupling ends of tumbling, to prevent to cause owing to the cargo weight inequality on the pallet fork 9 damage of dump ram 10, simultaneously, cylinder seal spare all adopts the NOK sealing member, can actv. guarantees the function and the service life of oil cylinder; The hydraulic fluid port of dump ram 10 contains the throttling sheet, can regulate the speed of the fork kinematic velocity of tumbling.During work, utilize the flexible of dump ram 10 piston rods, make swing arm 2-2 around bearing pin 4 swings, crotch plate 2 is realized the tilt functions of pallet fork 9 around the bearing pin swing thereby control is tumbled.

As Fig. 6, shown in Figure 7, described bearing pin 4 comprises axle core 4-1 of captiveing joint with dump cradle 1 and the axle sleeve 4-2 of captiveing joint with the crotch plate 2 of tumbling, its axis core 4-1 is coaxial to be embedded in the axle sleeve 4-2, and certain distance is stretched out in two ends in axle sleeve 4-2, and axle core 4-1 and axle sleeve 4-2 can relatively rotate around axis.In this example, axle sleeve 4-2 adopts the self-lubricating powder metallurgy sleeve, axle core 4-1 adopts the 40Cr material to make, the one end stretches out on the axle sleeve 4-2 periphery partly offers cannelure 4-1-1, close-fitting is installed rectangle stay 4-1-2 in this groove, dump cradle 1 is pressed in this stay side, utilize friction force between stay 4-1-2 and the dump cradle 1 to realize captiveing joint of axle core 4-1 and dump cradle 1, when bearing pin 4 is stuck (axle core 4-1 and axle sleeve 4-2 can't relatively rotate around axis), stay 4-1-2 is by wear down, make the relative dump cradle 1 of axle core 4-1 turn, can realize the upset of crotch plate 2 of tumbling equally, thereby prolong service life greatly.In addition, the built-in lubricating cup of present embodiment axle core 4-1, not only elegant in appearance, and can play the effect of lubricating axle core 4-1 and axle sleeve 4-2.
