Description
Technical field
The invention belongs to the loading-unload machine field, relate to fork truck, specifically, is the special-purpose arm of a kind of fork truck.
Background technology
Fork truck has another name called forklift, is a kind of loading-unload machine, and it is made up of car body, pallet fork, crane, door frame etc., be mainly used in the handling of goods, but the pallet fork of fork truck can only promote goods, can not lift goods.For this reason; Notification number is CN201553586; The Chinese patent that name is called " a kind of fork truck auxiliary boom " discloses a kind of fork truck boom structure, comprises support and cantilever, the base of support by a pair of vertical arrangement be parallel to each other and the cross section is that rectangular steel pipe constitutes; The top, horizontal of support is provided with the cantilever that stretches out support, and the end of cantilever is welded with suspension ring.The fork truck auxiliary boom of this kind structure has significant disadvantages: labor is following:
First; Support is made up of four pillars, and its left front, left back pillar arranges that 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 big; The level of cantilever in addition, the space of cantilever below is too narrow and small, is unfavorable for goods is hung charge and discharge operations.
The second, left front, the right front pillar of support arranges that 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 big; It is too many to take the and arranged on left and right sides space, and when pallet fork moved to the left or to the right, support was run into personnel and the goods that is positioned at both sides easily; Dangerous, also overslaugh driver's seat.
The 3rd, cantilever and support are welded into a whole, and volume is big, and heavy, can't decompose dismounting fast, are unfavorable for the fork truck translation function, become to promote the goods function from lifting goods functional shift.
The 4th, suspension ring are welded on the end of cantilever, and 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, though 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 then fork truck leans forward easily, lack of equilibrium.
The 5th, bracket base on the pallet fork of fork truck, does not have safety device through the band steel pipe box, and in pallet fork up-down and the front and back tilting procedure, bracket base comes off from the pallet fork of fork truck easily, and it is bigger that safety is drawn trouble.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide the special-purpose arm of a kind of fork truck, be installed on the pallet fork of fork truck, with the supporting use of fork truck; Make fork truck have the function of lifting goods, enlarged the loading and unloading scope of fork truck, and it is big to hang the charge and discharge operations space, is not easy to meet personnel and goods; Also not overslaugh driver's seat can decompose dismounting fast, is beneficial to the fork truck translation function; The center of gravity of goods can be adjusted, and is provided with safety rope, and the accident of having eliminated is drawn trouble.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The special-purpose arm of a kind of fork truck comprises support, cantilever, hook, and it is characterized in that: support is made up of base, left front pillar, left back pillar, right front pillar, right back pillar and top board; Base is a framed structure, is welded by left and right frame and forward and backward frame, and left and right frame and forward and backward frame all are made up of the band steel pipe; Lower end left front, left back pillar is welded on the left frame of base, and lower end right front, right back pillar is welded on the left frame of base, and upper end left front, left back, right front, right back pillar converges at top board; And be welded on the bottom surface of top board, top board is inclined upwardly, and the space angle of the left frame of left front pillar and base is 90 degree; Rectangular triangular support between the left frame of left front, left back pillar and base, the space angle of the left frame of right front pillar and base is 90 degree, rectangular triangular support between the left frame of right front, right back pillar and base; Be equicrural triangle between the front bezel of left front, right front pillar and base and support, be equicrural triangle between the back frame of left back, right back pillar and base and support, cantilever is made up of square steel tube; The bottom, rear portion of cantilever is welded with a gusset piece, is provided with reinforced rib between the left and right sidewall of gusset piece and cantilever, and gusset piece is connected with the top board of support through bolt fastener; Cantilever is provided with suspension ring; The bottom of suspension ring is provided with lug, and said hook is connected on the lug through bearing pin, and the front end of cantilever is welded with baffle plate; The side of suspension ring is provided with lock screw; The front end sealing of the left and right frame of base, the rear end is respectively arranged with opening, and the opening sleeve that left and right frame passes through its rear end respectively is on the pallet fork of fork truck; Be respectively arranged with lock screw on the lateral surface of left and right frame rear end, be provided with safety rope between the back frame of base and the crane of fork truck.
The acclivitous angle of said top board is between 5 degree to 15 degree.
The present invention has following positive beneficial effect:
First; Spatial relation between the left frame of left front, left back pillar and base is rectangular triangular support; Spatial relation between the left frame of right front, right back pillar and base also is rectangular triangular support, and the advantage of this supporting way is: the forward and backward width of support is less, and cantilever is acclivitous in addition; The space of cantilever below is very big, is beneficial to goods is hung charge and discharge operations.
Second; Spatial relation between the front bezel of left front, right front pillar and base is to be equicrural triangle to support; Spatial relation between the back frame of left back, right back pillar and base also is to be equicrural triangle to support, and 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 run into the personnel and the goods of both sides, also not overslaugh driver's seat.
The 3rd, cantilever is connected through bolt fastener with support, but at high speed is disassembled into two parts, is convenient to decompose the back and removes from the pallet fork of fork truck, helps the fork truck translation function, becomes to promote the goods function from lifting goods functional shift.
The 4th, hook is to be connected on the suspension ring, and suspension ring can move along cantilever is forward and backward, can change the center of gravity of the relative fork truck of goods, if the very heavy goods of lifting can move suspension ring backward, let the center of gravity of goods lean on after, make fork truck keep balance.
The 5th; The left and right frame of bracket base is enclosed within on the pallet fork of fork truck, has safety rope to connect, and safety rope is made up of a chain; The pallet fork of fork truck rises, descends, leans forward, in the layback process; Chain links together bracket base and crane all the time, and bracket base can not come off from the crane of fork truck, and the accident of having eliminated is drawn trouble.
