Abstract
The invention discloses an electric pallet truck with a speed-limiting device, comprising a motor, a truck body, balance wheels symmetrically installed on the bottom surface of the truck body, and an electronic control system, wherein pressure-inductive switches are disposed on the balance wheels; the pressure-inductive switches feed back a pressure-inductive signal into the electronic control system, and the electronic control system controls to output a current, so as to control the rotational speed of the motor. The electric pallet truck with a speed-limiting device in the proposal disclosed by the invention is provided with pressure-inductive switches on balance wheels at the both sides of a drive wheel. When a truck body steers, the pressure-inductive switches send the induced steering angular displacement signal instruction into an electronic control system, the electronic control system automatically calculates and processes to obtain the turning speed of the truck body, and then outputs a current to the truck body to control the rotational speed of a motor, so as to achieve control on running speed, thereby avoiding the occurrence of accident due to improper speed control when locomotive steers.
Description
Technical field
The present invention relates to a kind of electric pallet truck, relate in particular to a kind of electric pallet truck that when turning to, has speed-limit device, belong to the carrying vehicle technical field.
Background technology
The navigating mate that the formula electric pallet truck is driven at the station all stands on the transport trolley pedal to be operated, controls car body; If navigating mate is improper to turning velocity control when car body turns to; Or excessive velocities during break turn; The big easy lack of equilibrium of car body of centrifugal inertial force causes navigating mate to be thrown out of, accidents such as car body generation overturning.And existing transport trolley speed mostly with turn to irrelevantly, therefore when turning, influence traffic safety, have potential safety hazard.
Summary of the invention
Technical matters to above-mentioned existence the objective of the invention is: proposed a kind of electric pallet truck with speed-limit device that can effectively control the car body turning velocity.
Technical solution of the present invention is achieved in that a kind of electric pallet truck with speed-limit device, comprises that motor, car body, symmetry are installed in the balance wheel of car body bottom surface, electric-control system, and said balance wheel is provided with pressure-sensitive switch; Said pressure-sensitive switch in electric-control system, is controlled motor speed through the electric control system controls outgoing current with the pressure sensitive signal feedback.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Electric pallet truck with speed-limit device of the present invention is through being provided with pressure-sensitive switch on the balance wheel of drive wheel both sides.When car body turns to; Pressure-sensitive switch will be sensed the instruction of steering angular displacement high low signal and send in the electric-control system; After the automatic computing of electric-control system, draw its turning speed, then through its outgoing current is controlled rotating speed of motor; To reach the control road speed, cause the generation of accident when having avoided locomotive to turn to because of speed control is improper.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the Facad structure scheme drawing with electric pallet truck of speed-limit device of the present invention;
Accompanying drawing 2 is the control flow scheme drawing with electric pallet truck of speed-limit device of the present invention;
Wherein: 1, car body; 2, drive wheel; 3, balance wheel; 4, pressure-sensitive switch.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of electric pallet truck with speed-limit device of the present invention; Comprise that motor (not shown), car body 1, drive wheel 2, symmetry are installed in balance wheel 3, the electric-control system of car body 1 bottom surface and drive wheel 2 both sides, the rotating speed of said electric machine control balance wheel 3; Said balance wheel 3 is provided with pressure-sensitive switch 4; Said pressure-sensitive switch 4 in electric-control system, is controlled motor speed through the electric control system controls outgoing current with the pressure sensitive signal feedback.Car body 1 is when turning to; Pressure-sensitive switch 4 on the balance wheel 3 will send in the electric-control system after will sensing the instruction of balance wheel steering angular displacement high low signal; After the automatic computing of electric-control system; Draw its turning speed, then through to its outgoing current control motor speed, road speed when having controlled car body and turning to.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Electric pallet truck with speed-limit device of the present invention is through being provided with pressure-sensitive switch on the balance wheel of drive wheel both sides.When car body turns to; Pressure-sensitive switch will be sensed the instruction of steering angular displacement high low signal and send in the electric-control system; After the automatic computing of electric-control system, draw its turning speed, then through its outgoing current is controlled rotating speed of motor; To reach the control road speed, cause the generation of accident when having avoided locomotive to turn to because of speed control is improper.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
