The utility model discloses except the compound gyro wheel through both sides with outer mast and fork truck frame sliding connection, the activity about the fork truck frame that drives is connected to the chain of hydro -cylinder both sides in the middle of still utilizing, simple structure, can guarantee that fork truck rises to rise along with the hydro -cylinder and the balance is ascending steadily.

Description

A kind of forklift door frame
Technical field
The utility model relates to the door frame of fork truck, in particular a kind of forklift door frame.
Background technology
Chinese patent (notification number 202265367U, day for announcing 2012.06.06) disclose a kind of single-stage door frame of forklift, comprise door frame, fork frame and hoisting system, described hoisting system forms by being arranged on two lift oil tanks on door frame base side by side, this structure lifting fork support body must by two lift oil tank synchronous effects, its synchronism is poor, is difficult to ensure that fork frame rises evenly or declines, and easily causes tilting.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides the forklift door frame that a kind of structure is simple, balance is good.
For achieving the above object, technical solution of the present utility model is: a kind of forklift door frame, comprises outer mast, Forklift truck rack and is installed on the oil cylinder in the middle of outer mast; The piston rod part both sides of described oil cylinder are respectively wound with a chain; One end of described chain is fixedly connected with outer mast, and the other end is fixedly connected with Forklift truck rack; Described outer mast and Forklift truck rack are also by composite rolling wheel sliding block joint; Described outer mast both sides are all provided with bearing pin.
Preferably, the piston rod part both sides of described oil cylinder are respectively provided with a fixed pulley, and fixed pulley walked around by described chain.
Preferably, described outer mast includes two channel-section steels erect, and every side of Forklift truck rack is all provided with two composite rolling wheels, and described composite rolling wheel is slidably connected to channel-section steel, leaves point of view mouth between described channel-section steel and chain.
Preferably, be installed with cross bar between described two channel-section steels, described cross bar is fixedly connected with the first adapter plate, and one end of described two chains is individually fixed in the both sides of the first adapter plate; The rear end of described Forklift truck rack is installed with two piece of second adapter plate, and the other end of described two chains is individually fixed in corresponding second adapter plate.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is except the composite rolling wheel by both sides is by outer mast and Forklift truck rack sliding block joint, in the middle of also utilizing, the chain connecting band moving fork vehicle frame of oil cylinder both sides is up and down, structure is simple, can ensure fork truck hoist with oil cylinder and balance and stability rise.
Accompanying drawing explanation
Fig. 1 is structural perspective of the present utility model;
Fig. 2 is structural front view of the present utility model;
(1, outer mast; 11, channel-section steel; 12, cross bar; 13, base; 2, Forklift truck rack; 3, oil cylinder; 31, piston rod; 32, fixed pulley; 4, chain; 41, the first adapter plate; 42, the second adapter plate; 5, composite rolling wheel; 6, bearing pin; 7, point of view mouth).
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1-2, a kind of forklift door frame, comprises outer mast 1, Forklift truck rack 2, up and down oil cylinder 3 and two chains 4.Described outer mast 1 is formed with the cross bar 12 being connected two channel-section steels 11 primarily of base 13, the channel-section steel 11 that is erected at base 13 both sides, the first adapter plate 41 is installed with on front side of cross bar 12, the outside of two channel-section steels 11 is provided with the bearing pin 6 for being connected with fork truck, channel-section steel 11 outer lower portion be provided with tapped bore (not shown) for installing with fork truck.Be installed with two piece of second adapter plate 42 bottom described Forklift truck rack 2, every side in its back-end is all provided with two composite rolling wheels 5, adds up to 4 and meets roller 5, and wherein composite rolling wheel 5 is flush-mounted in channel-section steel 11 is that composite rolling wheel 5 is slidably connected in channel-section steel 11.Erect in the middle of described base 13 and have an oil cylinder 3 that can stretch up and down, wherein piston rod 31 both sides of oil cylinder 3 are respectively installed with a fixed pulley 32, and fixed pulley 32 walked around by chain 4; The first adapter plate 41 is fixed in one end of described chain 4, and the other end is fixed on the second adapter plate 42.Between chain 4 and channel-section steel 11, leave point of view mouth 7, in the middle part of two channel-section steels 11, just connection one is with cross bar 12 simultaneously, and effectively expanded the visual field of operator, convenient operation, increases work efficiency.
Embody rule of the present utility model: the piston rod 31 of oil cylinder 3 is upwards upheld, the Forklift truck rack 2 be fixedly connected with chain 4 one end will rise along with chain 4; And during oil cylinder 3 retracted downward, Forklift truck rack 2 will decline thereupon.
Above-described, be only preferred embodiment of the present utility model, the scope that the utility model is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
