Abstract
A fork truck direct current motor temperature warning device for protecting fork truck motors is characterized in that a temperature sensor is installed on a direct current motor of a fork truck, the temperature sensor is connected with a control circuit, data measured by the temperature sensor is displayed in an instrument panel through the control circuit, and when temperature sensors are simultaneously or individually installed on a running motor and a lifting motor, the running motor and the lifting motor can be observed and controlled. Adopting the scheme, the working temperature of the direct current motor can be observed through the instrument panel, which is visual and accurate. The fork truck direct current motor temperature warning device has the advantages that the working temperature of the direct current motor can be observed in time, and the service life of the motor can be prolonged.
Description
Technical field
The utility model relates to a kind of fork truck direct current machine temperature alarming device that the fork truck motor is protected.
Background technology
The direct current machine of electri forklift use does not at present generally have sensor installation, control system does not have temperature feedback signal, and the driver can't know the actual temperature situation of motor when operation, causes because of long-time overburden operation, motor temperature is too high, the situation that electrical machinery life is shortened greatly.
Summary of the invention
The purpose of this utility model just provides a kind of fork truck direct current machine temperature alarming device that can monitor the working temperature of direct current machine.
Solution of the present utility model is such: the direct current machine at fork truck is equipped with temperature sensor, and temperature sensor links to each other with control circuit, is shown in instrument board by the data of control circuit with temperature sensor measurement.Take such scheme, just can observe the working temperature of direct current machine by instrument board, accurately directly perceived.
At movable motor with promote all mounting temperature sensors of motor, just can observe control to movable motor and lifting motor; Also can be arranged separately in wherein on certain motor.
The utility model has the advantages that the working temperature that in time to observe direct current machine, prolong the working life of motor.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a fundamental diagram of the present utility model.
Accompanying drawing 2 is the utility model instrument detected temperatures circuit theory diagrams.
Accompanying drawing 3 is the schematic diagrames behind the utility model direct current machine mounting temperature sensor.
Accompanying drawing 4 is the structural representation of a kind of instrument board of the utility model employing.
Embodiment
The utility model is equipped with temperature sensor 3 at the direct current machine of fork truck, and temperature sensor 3 links to each other with control circuit, is shown in instrument board by the data of control circuit with temperature sensor measurement.
The present embodiment is simultaneously at the movable motor 1 of fork truck with promote temperature sensor mounted embodiment on the motor 2.
Fundamental diagram is seen accompanying drawing 1.When movable motor and lifting machine operation, the motor feels hot, the temperature of motor raises gradually, when the long-time overburden work of motor, the heat radiation of motor can not meet the demands, and the temperature of motor is raised to higher temperature, after instrument detects the heat alarm that temperature sensor sends, the alarm lamp of instrument is bright, and instrument is sent signal to alarm buzzer, and buzzer sends alarm sound.
The instrument of translator temperature alarm is seen accompanying drawing 4, and too high when the temperature of movable motor, movable motor 1 temperature alarm designated symbol 4 is bright on the instrument face plate, reminds driver's movable motor 1 temperature too high, notes avoiding overload to travel in order to avoid burn out movable motor.Too high when the temperature that promotes motor, the overheated code light of Oil pump electrical machinery 25 is bright on the instrument face plate, reminds the temperature that promotes motor 2 too high, notes avoiding the operation that overloads, and the temperature that prevents to promote motor is too high, burns out the lifting motor.
Claims (3)
1. a fork truck direct current machine temperature alarming device is characterized in that at the direct current machine of fork truck temperature sensor being installed, and temperature sensor links to each other with control circuit, is shown in instrument board by the data of control circuit with temperature sensor measurement.
2. fork truck direct current machine temperature alarming device according to claim 1 is characterized in that described direct current machine refers to movable motor (1).
3. fork truck direct current machine temperature alarming device according to claim 1 is characterized in that described direct current machine refers to promote motor (2).
