Abstract
The utility model discloses a kind of fork truck carries out automatic speed-limiting device when different angle of turn, comprise power supply, angle of turn potentiometer, speed sensor and controller; Power supply, angle of turn potentiometer, speed sensor are electrically connected with controller respectively, angle of turn potentiometer is for detecting the steering angle information of fork truck, speed sensor is for detecting the driving speed information of fork truck, controller is for controlling the moving velocity of fork truck, and controller also records different steering angle and the maximum travel speed corresponded in advance; The steering angle information received compares with the steering angle information recorded in advance by controller determines maximum travel speed, and when the driving speed information detected is greater than this maximum travel speed, controller controls fork truck and is reduced to this maximum travel speed.The utility model avoids the danger occurring to overturn by restriction moving velocity when fork truck is turned, further different steering angle can set with the value of the maximum travel speed corresponded.
Description
Technical field
The utility model relates to a kind of fork truck carries out automatic speed-limiting device when different angle of turn.
Background technology
Fork truck is one of carrying vehicle of commonly using of present people, be that member pallet cargo carries out loading and unloading, stacking and short range transport, weight transport operation various wheeled carrying vehicle.Be widely used in harbour, station, airport, goods yard, factory floor, warehouse, Transfer center and DISTRIBUTION CENTRE etc., and can enter carry out pallet cargo in cabin, compartment and freight container handling, transport operation, be requisite equipment in pallet traffic, Container Transport.
Current fork truck is in different angle of turn situations, speed of a motor vehicle maxim is not restricted, such as: one is turned left or right-hand rotation maximum angle 90 degree, the fork truck of the max speed 10.5km/h, in maximum angle of turn situation, the speed of a motor vehicle still can reach 10.5km/h, can cause the quick sharply turning in original place or with the unexpected sharply turning of the max speed straight-line travelling, and the danger that fork truck occurs to overturn in the case is larger.
Given this, the present inventor develops a kind of fork truck carries out automatic speed-limiting device when different angle of turn specially, and this case produces thus.
Utility model content
A kind of fork truck that the utility model provides carries out the device of automatic speed-limiting when different angle of turn, maximum travel speed when it can be turned according to different angle of turn volitional checks when fork truck is turned, and avoids the danger occurring to overturn.
To achieve these goals, the technical solution of the utility model is as follows:
Fork truck carries out a device for automatic speed-limiting when different angle of turn, comprise power supply, angle of turn potentiometer, speed sensor and controller; Power supply, angle of turn potentiometer, speed sensor are electrically connected with controller respectively, angle of turn potentiometer is for detecting the steering angle information of fork truck, speed sensor is for detecting the driving speed information of fork truck, controller is for controlling the moving velocity of fork truck, and controller records different steering angle and the maximum travel speed corresponded in advance; The steering angle information received is carried out contrast with the steering angle information recorded in advance and is corrected to obtain accurate steering angle to determine maximum travel speed by controller, when the driving speed information detected is greater than this maximum travel speed, controller controls fork truck moving velocity and is reduced to this maximum travel speed.
Described angle of turn potentiometer is arranged on forklift steering wheel place, and speed sensor is arranged on drive motor place.
Described controller is also electrically connected with drive motor, controls the moving velocity of fork truck by controlling drive motor.
After adopting such scheme, the steering angle information that the utility model is detected by controller reception angle of turn potentiometer, determine the maximum travel speed that fork truck allows under this steering angle, and the moving velocity controlling fork truck is in this maximum travel speed, ensures that fork truck will cause fork truck to be turned on one's side because turning velocity is too fast.

Label declaration
Power supply 1, angle of turn potentiometer 2, speed sensor 3, controller 4, steering handwheel 5, drive motor 6.
Detailed description of the invention
As Figure 1-4, be that a kind of fork truck that the utility model discloses carries out the device of automatic speed-limiting when different angle of turn, comprise power supply 1, angle of turn potentiometer 2, speed sensor 3 and controller 4; Power supply 1, angle of turn potentiometer 2, speed sensor 3 are electrically connected with controller 4 respectively.
Potentiometer is arranged on forklift steering wheel 5 place, for detecting the steering angle information of fork truck.Speed sensor 3 is arranged on drive motor 6 place, for detecting the driving speed information of fork truck.Controller 4 is electrically connected with drive motor 6, and control the moving velocity of fork truck by controlling drive motor 6, controller 4 records the maximum travel speed corresponding from different steering angle in advance.
The steering angle information received is carried out contrast with the steering angle information recorded in advance and is corrected by controller 4, to obtain accurate steering angle to determine maximum travel speed, when the driving speed information detected is greater than this maximum travel speed, controller 4 controls fork truck moving velocity and is reduced to this maximum travel speed.The steering angle information that angle of turn potentiometer 2 detects is received by controller 4, determine the maximum travel speed that fork truck allows under this steering angle, by controlling the moving velocity of fork truck in this maximum travel speed, ensure that fork truck will cause fork truck to be turned on one's side because turning velocity is too fast.
Concrete steering angle and permission maximum travel speed relation can be as follows, as shown in Figure 5, wherein the positive and negative of angle represents that fork truck turns left and turns right respectively, due to fork truck when straight-line travelling in order to ajust direction, once in a while also can low-angle rotation steering handwheel 5, if now limited speed does not obviously meet actual conditions, therefore controller 4 is when detecting that steering angle is less than 20 degree, do not carry out speed limit, namely corresponding maximum turning speed is the maximum travel speed 10km/h of fork truck own, same carry out spot turn at fork truck and turn to hourly velocity can not be too low, no person turns around to turn to slow, therefore controller 4 is when detecting that steering angle is greater than 65 degree, namely turning around to turn to hourly velocity to limit is all 3km/h, and fork-truck steering angle and permission maximum travel speed linearly change between 20-65 degree.
The steering angle that its middle controller 4 is recorded in advance and maximum travel speed value corresponding thereto not only limit the value that the present embodiment provides, the maximum travel speed that user is corresponding under can arranging different steering angle according to the demand of different operating mode.
The controller 4 with above-mentioned functions is prior art, directly can obtain from market.
These are only preferred embodiment of the present utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
