Description
Technical field
The utility model belongs to the loading-unload machine field, relates to fork truck, specifically, is a kind of Special crane jib for forklift truck.
Background technology
Fork truck has another name called forklift, is a kind of loading-unload machine, and it is comprised of car body, pallet fork, crane, door frame etc., is mainly used in the handling of goods, but the pallet fork of fork truck can only cargo lifting, can not lift goods.Particularly, when goods was used packaging bags, the pallet fork of fork truck was easily inserted packaging bag broken.
Notification number is CN201553586, the Chinese patent that name is called " a kind of forklift auxiliary boom " discloses a kind of fork lifter boom structure, comprise support and cantilever, the base of support is that rectangular steel pipe forms by pair of parallel in pallet fork and cross section, the top level of support is provided with the cantilever that stretches out support, and the end of cantilever is welded with suspension ring.The forklift auxiliary boom of this kind structure has obvious shortcoming, and labor is as follows:
First, support is comprised of four pillars, its left front, left back pillar is arranged by isosceles trapezoid, right front, right back pillar is also arranged by isosceles trapezoid, the shortcoming of this arrangement is: the front and back width of support is too large, the level of cantilever in addition, the space of cantilever below is too narrow and small, is unfavorable for goods is hung to charge and discharge operations.
Second, left front, the right front pillar of support is arranged by isosceles trapezoid, left back, right back pillar is also arranged by isosceles trapezoid, the shortcoming of this arrangement is: the left and right width of support is too large, take the arranged on left and right sides space too many, when pallet fork moved to the left or to the right, support was easily encountered personnel and the goods that is positioned at both sides, dangerous, also overslaugh driver's seat.
The 3rd, cantilever and support welding are in aggregates, and volume is large, and heavy, can't dismantle by fast decoupled, are unfavorable for the fork truck translation function, from lifting goods functional shift, become the cargo lifting function.
The 4th, suspension ring are welded on the end of cantilever, suspension ring can not carry out forward and backward adjustment along the direction of stretching out of cantilever, also just can't change the center of gravity of the relative fork truck of goods, although the fork truck maneuverability, its wheel base is shorter, if lift very heavy goods, the center of gravity of goods is very forward again, and fork truck easily leans forward, lack of equilibrium.
The 5th, bracket base is enclosed within on the pallet fork of fork truck by Flat steel pipe, there is no safety device, pallet fork lifting and tilting forward and back in process, and bracket base easily comes off from the pallet fork of fork truck, and it is larger that safety is drawn trouble.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of fork truck arm, be arranged on the crane of fork truck, with fork truck, support the use, make fork truck have the function of lifting goods, enlarged the loading and unloading scope of fork truck, energy Fast Installation and dismounting, be beneficial to the fork truck translation function.
For achieving the above object, the present invention is by the following technical solutions:
A kind of fork truck arm, comprise support, cantilever, hook, it is characterized in that: also comprise two equilibrium arms, buckle, described fork truck is connected on the crane of fork truck with arm by buckle;
Described support is a square tube that vertically arranges in the vertical direction;
Described cantilever is the square tube that an end is welded on a positive side of top of the trellis, and cantilever is perpendicular to support;
End that is positioned at cantilever of described two equilibrium arms, another root are positioned at the cantilever middle part, and equilibrium arm is all perpendicular to support and cantilever;
Described hook is positioned at the two ends of equilibrium arm;
Described buckle is provided with the groove that Open Side Down, and buckle is welded on the trailing flank at middle part of support.
Further, described welding hook is at the two ends of equilibrium arm, and hook is in horizontality.
Further, described welding hook is at the two ends of equilibrium arm, and hook is in state obliquely, and the angle of inclination is 5 degree-15 degree.
Further, described welding hook away from support one side, is linked up with triangular in shapely at the two ends of equilibrium arm, and its upper surface is planar structure and is in horizontality.
Further, described welding hook away from support one side, is linked up with triangular in shapely at the two ends of equilibrium arm, and its upper surface is planar structure and is in state obliquely, and the angle of inclination is 5 degree-15 degree.
Further, between described support and cantilever, be provided with the stay bearing plate of reinforcement effect.
Further, on described support, also be connected with a square tube be used to preventing that support from rotating along its axle center, described square tube is perpendicular to support and cantilever, and its length is greater than the width of fork truck crane.
During article hoisting, at first fork truck is connected to by buckle with arm on the middle transverse arm of crane of crane of fork truck, at this moment, the top of support is concordant with the Top Crossbeam of the crane of fork truck, and the bottom of support is concordant with the lower cross arm of the crane of fork truck.The hanging belt of the article that will lift hangs on the hook at equilibrium arm one, equilibrium arm two two ends, promotes crane, and fork truck just can will be sling by article hoisting reposefully.After arriving destination, move down crane, the fork truck reversing back, just can, by hook from hanging belt, extracting, complete and transport.
This device not only can be used to transporting, can also be for piling.The present invention has following positive beneficial effect:
The first, cantilever is provided with two equilibrium arms, and hook connecting is connected on the two ends of equilibrium arm, the stability that is conducive to lift.
Second, support vertical is vertical to be established and makes the bottom of support lean against the crane bottom, and cantilever is connected on the crane of fork truck, itself just has certain stability, slow at the fork truck running velocity, when goods is lighter, the advantage of this supporting way is: the left and right width of support is less, when pallet fork left and right when mobile, support is not easy to encounter personnel and the goods of both sides, also not overslaugh driver's seat.Further also be provided with a square tube be used to preventing that support from rotating along its axle center, described square tube is perpendicular to support and cantilever, and its length, greater than the width of fork truck crane, can prevent that support from rotating.
The 3rd, the hollow steel pipe of the many employings of whole device, lightweight, by bayonet socket, with crane, be connected, can realize Fast Installation and dismounting, be conducive to the function conversion that fork truck realizes that cargo hoisting and goods are lifted.
The 4th, the hook hook portion is in horizontality or is in state slightly obliquely, while unloading goods, moves down crane, and the fork truck reversing back just can be by hook from extracting rope, and the middle hook that adopts bending, can complete automatic unloading compared to existing technology.
