The invention can move up and down along with the sliding rod support of inner door 3, and incline with the lifter 7. The invention can swing fork and increase working face, with simple structure and high stability.

Description

Fork arm swing device of forklift truck

One, technical field

The present invention is the pallet fork pendulous device that a kind of fork truck is used.

Two, background technology

Pallet fork at existing fork truck mostly is by using the rotation of oil cylinder control lifting door frame, control pallet fork angle of inclination forward, pallet fork is swung forward, like this, making the loading and unloading operation of fork truck be subjected to bigger restriction.Particularly narrow and small place, relatively by the cargo handing of lining, and the interim freight house of open-air fluffy formula, with the loading and unloading of the breast board transport trolley of fluffy bar, freight container and other items, bring very big difficulty.

Three, summary of the invention

The objective of the invention is provides a kind of fork arm swing device of forklift truck for the fork truck of handling goods; It can make the pallet fork swing, has increased the scope of operation of fork truck, the loading and unloading maneuverability, and job stabilization is good; Can satisfy narrow and small place and relatively by the cargo handing of lining, and the interim freight house of open-air fluffy formula, need with the loading and unloading of the breast board transport trolley of fluffy bar, freight container and other items; And it is simple in structure, easy to operate.

For achieving the above object, the technical scheme that the present invention takes is: be provided with the pallet fork pendulous device between pallet fork and door frame bont, the pallet fork pendulous device includes compositions such as balladeur train, pendulous device, oscillating oil cylinder.The upper end of balladeur train is fixed on the sliding rod frame in the inner upright mounting of door frame bont, the lower end of balladeur train is provided with and is installed in the pulley in the side guidance in the inner upright mounting, balladeur train by its pulley be installed on the inner upright mounting, and can be with sliding rod frame one lifting, pendulous device and balladeur train articulated lifting arm, the pallet fork device is fixed on the pendulous device, an end of oscillating oil cylinder and the lower end articulated lifting arm of balladeur train, the other end and pendulous device articulated lifting arm.By oscillating oil cylinder drive pendulous device with the balladeur train hinge-point be the center swing, drive the swing of pallet fork device by pendulous device, thereby realize the swing of pallet fork.

The version of pendulous device is a lot, can include compositions such as swing arm, fork.One end and balladeur train articulated lifting arm, the other end of swing arm are hinged with fork, and fork and pallet fork device are fixedly connected, swing arm also with the oscillating oil cylinder articulated lifting arm.Driving swing arm by oscillating oil cylinder, is the center swing with the hinge-point of swing arm and balladeur train, and swing arm drives the pallet fork device by fork and swings.

Because the present invention is provided with the pallet fork pendulous device between pallet fork device and door frame bont, the pallet fork device is under the effect of its oscillating oil cylinder, can drive the pallet fork device is that swing at the center with the hinge-point of swing arm and balladeur train, like this, pallet fork just can load and unload than the narrow gap that puts in of big distance; Fork truck is when the band shipping is defeated, and pallet fork can be put later on, moves the stability when still keeping the shipping of fork truck band defeated after making the goods center of gravity.Therefore, the present invention has can make the pallet fork swing, has increased the scope of operation of fork truck, the loading and unloading maneuverability, and job stabilization is good; And simple in structure, characteristics such as easy to operate.Can satisfy narrow and small place and relatively by the cargo handing of lining, the interim freight house of particularly open-air fluffy formula, need with the loading and unloading of the breast board transport trolley of fluffy bar, freight container and other items.

Four, description of drawings

Fig. 1 is a scheme drawing of the present invention;

Fig. 2 is that the A of Fig. 1 is to view.

Five, the specific embodiment

Accompanying drawing is one embodiment of the present of invention, includes compositions such as balladeur train 1, pendulous device, oscillating oil cylinder 2.Balladeur train 1 is a rectangle, and the sliding rod frame in the inner upright mounting 3 of its upper end and door frame bont 7 is fixedly connected, and two outsides of its lower end respectively are provided with pulley, and pulley is placed in the guide groove of inner upright mounting 3 inboards.Pulley also can directly adopt bearing.Pendulous device is made up of swing arm 4, fork 5 etc.Swing arm 4 is four, is arranged in the both sides of balladeur train 1, one end and balladeur train 1 articulated lifting arm.Fork 5 is two; Also be arranged in the both sides of balladeur train 1, the other end articulated lifting arm of each fork 5 and two swing arms 4 of homonymy; Fork 5 is fixedly connected with pallet fork device 6.Like this, the fork 5 of every side, balladeur train 1, two swing arms 4 form the bar linkage structure of parallelogram.The lower end articulated lifting arm of the lower end of oscillating oil cylinder 2 and balladeur train 1, its upper end and swing arm 4 articulated lifting arms; Oscillating oil cylinder 2 is a lot of with swing arm 4 pivotally attached connecting modes, can adopt between the swing arm 4 of two upper lateral parts pipe link is set, oscillating oil cylinder 2 and this pipe link articulated lifting arm.

When needs are swung, drive swing arm 4 by oscillating oil cylinder 2 by pipe link, swing arm 4 drives pallet fork devices 6 by fork 5, is that swing at the center with the hinge-point of swing arm 4 and balladeur train 1; When the bottom, protract, on move after when putting.

And whole the present invention can under the effect of inner upright mounting elevating ram, move up and down with the sliding rod frame in the inner upright mounting 3, and can tilt forward and back the motion operation with door frame bont 7.

Therefore the present invention has can make the pallet fork swing, has increased the scope of operation of fork truck, the loading and unloading maneuverability, and job stabilization is good; And simple in structure, characteristics such as easy to operate.Can satisfy narrow and small place and relatively by the cargo handing of lining, the interim freight house of particularly open-air fluffy formula, need with the loading and unloading of the breast board transport trolley of fluffy bar, freight container and other items.
