Abstract

The invention discloses a piling car with a steering speed limiting function, which comprises a piling car body and a steering driving device. The steering driving device mounted on the piling car body comprises an operational handle, a connecting arm is arranged below the operational handle and provided with a speed limit sensing switch, an electric control system and a motor are arranged in the piling car body, and a driving wheel is mounted on an output shaft of the motor. During steering of the piling car body, the speed limit sensing switch transmits steering speed signals to the electric control system, and steering speed of the piling car body is controlled by controlling input current of the motor through computation of the electric control system. During turning of the piling car body, the speed limit sensing switch sends out commands, the electric control system computes and processes the commands automatically to acquire the turning speed of the piling car body, output current of the motor is controlled and rotation thereof is accordingly controlled to realize control of running speed of the piling car, and accidents caused by improper speed during steering of the piling car are avoided, thereby the piling car with the steering speed limiting function is quite safe and reliable.

Description

technical field

[0001] The invention relates to a stacker truck, in particular to a stacker truck with a speed-limiting function when turning, and belongs to the technical field of transport vehicles. Background technique

[0002] The driver of the stand-on warehouse stacker truck operates and controls the stacker truck by standing on the pedal of the stacker truck. And the existing stacker truck is infinite speed control device when turning, if like this when the stacker truck turns if the driver improperly controls the steering speed, as the speed is too fast, it is easy to lose balance, and the inertia of the stacker truck is relatively high now. If it is large, it will cause the danger of the driver being thrown out or the stacker truck tipping over, which poses a great safety hazard to both the person and the locomotive. Contents of the invention

[0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a stacker tr...

Examples

Embodiment Construction

[0011] The present invention is described below in conjunction with accompanying drawing.

[0012] attached figure 1 , 2 It is a stacker truck with a steering speed limit function according to the present invention, which includes a car body 1 and a steering drive device installed on the car body 1. The steering drive device includes a joystick 2; A connecting arm 3 is provided; the connecting arm 3 is provided with a speed limit sensor switch 4; an electric control system and a motor are also provided in the car body 1; the output shaft of the motor is connected to the driving wheel 5; 1 When turning, the speed limit sensor switch 4 transmits the steering speed signal of the connecting arm 3 to the electronic control system, and the electronic control system calculates and controls the turning speed, and controls its output current to the motor, thereby controlling the steering of the car body 1 Speed ​​ensures driving safety.

[0013] Due to the application of the above-m...
