Abstract

The invention provides a starting motor protection structure and method and a telescopic arm forklift, and relates to the technical field of forklifts. The starting motor protection structure comprises a controller, a sensor for measuring the main oil pressure of a forklift hydraulic system and a starting switch for controlling starting and stopping of a starting motor; and the sensor is connectedwith the controller, and when a pressure value measured by the sensor is not less than a set value, the controller controls the starting switch to be in the off state. The starter motor protection method is used for the starting motor protection structure, the pressure value of the main oil pressure of the forklift hydraulic system is obtained through the sensor, and the controller compares the measured pressure value with the set value; if the measured pressure value is not less than the set value, the starting switch is controlled to be in the off state; and if the measured pressure value is less than the set value, the starting switch is controlled to be in the closed state. The starting motor protection method is adopted in the telescopic arm forklift, the telescopic arm forklift comprises a forklift body and the starting motor protection structure, and the technical effect of low maintenance cost is achieved.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a starter motor protection structure and a method thereof and a telescopic arm forklift. Background technique [0002] The load-sensing pump of the hydraulic system is directly connected to the gearbox. When the hydraulic system is under pressure, the load-sensing pump will generate a very large starting resistance torque, which will cause the output shaft of the gearbox to be stuck, making the engine unable to start. If the operator starts the engine forcibly, it will cause the starter motor to stall and damage the starter motor. A common way to protect the starter motor is to configure a fuse on the positive pole of the starter motor. However, when the positive fuse of the starter motor is burned out, it needs to be replaced, and it is very troublesome to replace the positive fuse of the starter motor, and the cost of using the positive fuse of the starter motor to protect t...
