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

Abstract

The invention relates to a speed control method, device, crane, electronic equipment and computer-readable medium of equipment with a hoisting mechanism. The method includes: obtaining in real time the position offset information of the winch handle in the winch mechanism of the equipment; when the position offset information satisfies the parking control condition, generating a displacement change rate according to the position offset information; When the speed meets the preset condition, a speed control strategy is generated based on the average speed deceleration phase, the variable speed deceleration phase, and / or the position offset information, and / or the preset speed curve and the preset deceleration; based on the speed control strategy Speed ​​control is carried out on the hoisting direct drive motor of the equipment, so that the bodywork system of the equipment can decelerate and stop. The speed control method, device, crane, electronic equipment and computer readable medium of the equipment with hoisting mechanism involved in the present invention can not only provide the driver with a way to quickly stop the equipment by only relying on the hoisting handle, but also avoid Braking shock caused by stopping.

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
