Automatic power take-off device and method

Abstract

The invention provides an automatic power takeoff disconnecting device and method and relates to the field of cranes. Through the automatic power takeoff disconnecting device and method, when power takeoff disconnecting get-off operation needs to be conducted on a crane, a user only needs to input an automatic power takeoff disconnecting instruction, a control module controls a clutch and a power takeoff to be disconnected according to the automatic power takeoff disconnecting instruction; when the clutch and the power takeoff are disconnected successfully, a transmission is controlled to return a neutral gear; then, a first gear signal sent by a first inductive switch is received, and a transfer case is controlled to engage the driving gear through the first gear signal; and finally, after the transfer case engages a driving gear, an electronic throttle and an engine are controlled to switch from a get-on operation state to a get-off operation state, and accordingly power takeoff disconnecting through one key is achieved. The operation procedure is simple, a large number of time costs and labor costs are saved, and the operation experience feeling of the user is promoted.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an automatic force take-off disconnection device and method. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, aerial crane, and crane. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Among them, cranes include all-terrain cranes, which are high-performance products with the characteristics of both truck cranes and rough-terrain cranes. It can not only transfer quickly and travel long distances like a truck crane, but also meet the requirements of working on narrow and rough or muddy grounds, that is, fast drivi...

AI Technical Summary

Problems solved by technology

[0003] The all-terrain cranes in the prior art include a class of centralized drive cranes, that is, a motor is used to drive a long transmission shaft to drive the driving wheels on both sides. The transmission system of the transfer case has a complicated control system, and it is necessary to manually detect the status of each part of the crane one by one to realize the power take-off of the crane. The operation process is complicated, a lot of time and labor costs are wasted, and the user experience is poor.
