Speed control method and device, crane, electronic device and readable medium

Abstract

The invention relates to a speed control method and device for equipment with a hoisting mechanism, a crane, an electronic equipment and a computer readable medium. The method comprises the steps that position deflection information of a hoisting handle in the hoisting mechanism of the equipment is obtained in real time; when the position deflection information meets a stopping control condition, a displacement change rate is generated according to the position deflection information; when the displacement change rate meets a preset condition, a speed control strategy is generated on the basis of a uniform speed deceleration stage, a variable speed deceleration stage, and / or the position deflection information, and / or a preset speed curve and a preset deceleration; and speed control is conducted on a hoisting direct-drive motor of the equipment on the basis of the speed control strategy so as to make a loading system of the equipment decelerate and stop. By means of the speed control method and device for the equipment with the hoisting mechanism, the crane, the electronic device and the computer readable medium, the mode that the equipment is rapidly stopped through only the hoisting handle can be provided for a driver, and braking impact caused by rapid stopping can be avoided.

Description

technical field [0001] The present invention relates to the field of starter control, in particular to a speed control method, device, crane, electronic equipment and computer-readable medium of equipment with a hoisting mechanism. Background technique [0002] The equipment that controls the hoisting mechanism through the handle to lift objects can include truck cranes, tower cranes, gantry cranes, rotary drills, etc. They are an indispensable and important product in the field of construction machinery because of their flexible working methods Simple and efficient, it is widely used in infrastructure, rescue, urban construction and other industries. [0003] Without loss of generality, take a crane as an example. The hoisting speed of the crane is affected by the opening of the hoisting handle operated by the driver. The larger the opening of the hoisting handle, the faster the hoisting speed, and the smaller the opening of the hoisting handle. then the speed is smaller. ...

AI Technical Summary

Problems solved by technology

In this way, the driver cannot control the deceleration time through the operating handle, but must press a specific emergency stop button to stop. This parking method requires a high reaction speed of the driver.

Moreover, in order to achieve the purpose of fast parking, the controller on the crane does not judge the running speed of the motor when the brake is put in, but directly performs the braking operation. This method is also likely to cause severe braking impact, which may cause the crane to overturn and lift Serious accidents such as broken arms
