The arc-shaped induction bar is arranged on the upper surface of the speed reducer gear, the proximity switch is arranged at the position, corresponding to the arc-shaped induction bar, on the speed reducer mounting plate and connected with the steering motor through the controller, the steering motor is meshed with the speed reducer gear through the transmission gear, and the mechanical limiting devices are symmetrically arranged on the circumference of the speed reducer gear. The automatic resetting device of the tire of the electric reach forklift truck has the advantages that the automatic resetting device is simple in structure, convenient to implement and low in cost; the proximity switch on the speed reducer mounting plate detects the position of the arc-shaped induction bar on a speed reducer and transmits a detection signal to the controller, the controller judges the position of the steering wheel and then controls the steering motor to rotate or stop, thus, automatic resetting of a steering wheel can be achieved in the starting process, the running route of the vehicle is determined, and safe operation is ensured.

Description

A kind of electric forward formula fork truck tire automatic reset device
Technical field
The utility model relates to a kind of fork truck, relates in particular to a kind of electric forward formula fork truck tire automatic reset device.
Background technology
At present, along with the develop rapidly of economy and logistics, electronic warehousing forklift because its noise is little, flexible and convenient operation, emission-free discharging, the advantage such as operate steadily, obtained application more and more widely.Electric forward formula fork truck adopts the structure of drive axle and retarder one, and steer motor is arranged on the retarder adapter plate, and wheel flutter is directly controlled by movable motor.Because the steering tire of electric forward formula fork truck is smaller, installation site is more hidden, and the position of wheel flutter is not easy to determine, when vehicle operating, can't determine the running route of vehicle, can not guarantee safe in operation, there is potential safety hazard, need the driver to get off and check the position of wheel flutter.Be badly in need of a kind of automatic reset device for this phenomenon, automatically reset while realizing the wheel flutter start from mechanical and electric two aspects.
The utility model content
Technical problem to be solved in the utility model is: a kind of electric forward formula fork truck tire automatic reset device is provided, while realizing start, wheel flutter automatically resets, need not the driver and get off and check the position of wheel flutter, accurately determine the running route of vehicle, guarantee safety of operation.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of electric forward formula fork truck tire automatic reset device, comprise reducer gear 1, arc induction bar 2, retarder adapter plate 3, approach switch 4, controller 5, steer motor 6, transmission gear 7 and mechanical stop limiter 8, reducer gear 1 upper surface arranges arc induction bar 2, and position corresponding with arc induction bar 2 on retarder adapter plate 3 arranges approach switch 4, and approach switch 4 is connected with steer motor 6 by controller 5, steer motor 6 is meshed with reducer gear 1 by transmission gear 7, is symmetrical arranged mechanical stop limiter 8 on reducer gear 1 circumference.
Described arc induction bar 2 is metal arc induction bar.
Described arc induction bar 2 is Q235 arc induction bar.
Between the bottom surface of described approach switch 4 and arc induction bar 2, distance is 2-3mm.
Described approach switch 4 is magnetic approach switch or Hall-type approach switch.
Described controller 5 is micro controller system.
Described mechanical stop limiter 8 is limiting stopper.
Principle of work of the present utility model: the reducer gear upper surface arranges arc induction bar, the retarder adapter plate is installed on vehicle frame, approach switch is installed on the retarder adapter plate, guarantee that approach switch and arc induction bar are on same vertical plane, make approach switch can sense the position of arc induction bar, be symmetrical arranged mechanical stop limiter on the reducer gear circumference and make tire be merely able to rotation in 90 degree of left and right.When approach switch detects arc induction bar, approach switch output 12v signal is to controller, controller judges by programmed logic, control steer motor with left-hand revolution, thus the reducer gear clickwise, and tire rotation angle diminishes, when approach switch just can't detect arc induction bar, the approach switch output voltage drops to 0V from 12V, after controller receives the voltage signal of variation, controls steer motor and stops action.Then controller is controlled the steer motor inching, revises the angle of wheel flutter, and wheel is just returned.
The beneficial effects of the utility model are: 1, simple in structure, it is convenient to implement, and cost is lower.2, by mechanical stop limiter, wheel flutter is rotated in the scope of 90 ° of left and right, approach switch on the retarder adapter plate detects the position of arc induction bar on retarder, detection signal is passed to controller, then the position of controller judgement wheel flutter is controlled the rotation of steer motor and stops, while realizing start, wheel flutter automatically resets, determine the running route of vehicle, guarantee safe in operation.
