The fork of forklift truck height induction device
Technical field
The utility model relates to a kind of electri forklift, specifically is the pallet fork height induction device of fork truck.
Background technology
Electri forklift is a kind of handling machinery, and it has walking and promotes the function of goods.The pallet fork hoisting depth of fork truck in the market can only come decision height only according to naked eyes.Especially pile on height and the three-dimensional stacking, when more than the elevated height to 3 meter, just be difficult to the naked eye grasp its height.And three-dimensional stacking and the high hoisting depth of heap be all more than 8 meters, and the complete manual control of the lifting of electri forklift pallet fork is judged by the experience of operating personal substantially, operation inconvenience, and can not guarantee safety of operation.
Summary of the invention
The purpose of this utility model just provides a kind of pallet fork height induction device of fork truck.
The utility model comprises forklift door frame and pallet fork support body, and the pallet fork support body is movably arranged on the door frame, can move up and down along door frame.The pallet fork support body is provided with induction wheel, and the line of induction twines along the circumference of induction wheel, and two of the line of induction is separately fixed on the upper and lower crossbeam of door frame.Inductor and the coaxial setting of induction wheel, inductor is connected with forklift operator panel signal.
When the utility model moves up and down at the pallet fork support body, the line of induction drives induction wheel and rotates, and inductor receives the induction wheel turn signal, will rotate lap signal and send control system to, according to the girth of induction wheel, the distance that the pallet fork support body moves up and down just can show by the forklift operator panel.The operator just can accurately know the distance of pallet fork operation like this, and is easy to operate, and guarantees safety of operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the fork of forklift truck height induction device comprises forklift door frame 1 and pallet fork support body 2, and pallet fork support body 2 is movably arranged on the door frame 1, can move up and down along door frame 1.2 are provided with induction wheel 3 on the pallet fork support body, and the line of induction 5 twines a circle along the circumference of induction wheel 3, and two of the line of induction 5 is separately fixed on the upper and lower crossbeam of door frame 1.Inductor 4 and induction wheel 3 coaxial settings can receive the turn signal of induction wheel 3, and inductor 4 is connected with forklift operator panel signal.
Pallet fork is arranged on pallet fork support body front end, and when door frame moved up and down, the induction wheel that the line of induction drives on the pallet fork support body rotated at the pallet fork support body, and inductor receives the induction wheel turn signal, will rotate lap signal and send control system to.According to the girth of induction wheel and the number of turns of rotation, just can obtain the distance that the pallet fork support body moves up and down, and show by the forklift operator panel.The operator does not need goods is just judged like this, and as long as just can accurately know the distance that pallet fork moves by the forklift operator panel, easy to operate, and guaranteed safety of operation.
