Embodiment Construction

[0053] see figure 1 , is a schematic flowchart of an embodiment of the boom telescoping follow-up control method of the present invention. In this embodiment, the boom telescopic follow-up control method includes:

[0054] Step S101, when the telescopic oil cylinder drives the bolt mechanism to move, detect in real time whether the position of the bolt mechanism belongs to the high-speed moving area or the low-speed moving area.

[0055] Before this step S101, the user first inputs the purpose state that the boom needs to be extended, and then activates the automatic telescopic switch, and the telescopic oil cylinder drives the bolt mechanism to insert the bearing pin on the multi-section arm. When the multi-section arm needs to be extended , the telescopic oil cylinder drives the latch mechanism to find the tail of the j-th telescopic arm to be extended, and stretches out the working pin to lock the telescopic oil cylinder and the j-th telescopic arm to ensure that the j-th ...

Abstract

The invention discloses a telescopic follow-up control method and a system of a suspension arm. The method comprises the steps of: detecting whether the position of a latch pin mechanism is located in a high speed moving region or a low speed moving region when a telescopic oil cylinder drives the latch pin mechanism to move; obtaining the high speed moving speed required by the latch pin mechanism in the high speed moving region, and obtaining the low speed moving speed required by the latch pin mechanism in the low speed moving region; calculating a matched rotating speed N required for driving the engine of the telescopic oil cylinder according to the high speed moving speed or the low speed moving speed of the latch pin mechanism; and setting the matched rotating speed N as the current rotating speed of the engine. According to the embodiment of the invention, the matched rotating speed N required for driving the engine is calculated according to the moving speed of the latch pin mechanism and the rotating speed of the engine is intelligently and accurately adjusted to be the matched rotating speed N, so that the rotating speed of the engine is matched with the expansion speed of the latch pin mechanism, thereby avoiding the risk factors caused by manual operation errors and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical booms, in particular to a boom telescopic follow-up control method and system of a multi-section arm of a single telescopic oil cylinder. Background technique [0002] In the prior art, mechanical booms, especially large-scale construction machinery booms, generally adopt the telescopic mode of single telescopic oil cylinder and multi-section boom, and its working principle includes: [0003] Step S01, the telescopic oil cylinder drives the latch mechanism to find the tail of the j-th telescopic boom to be extended; [0004] Step S02, extending the working pin to lock the telescopic oil cylinder with the j-th telescopic arm, retracting the j-th telescopic arm to insert the load pin in the j-1th telescopic arm; [0005] Step S03: Stretch the telescopic oil cylinder, and at the same time extend the telescopic arm of the jth section. After reaching the target position, the latch mechanism release...
