Embodiment approach

[0100] An embodiment provided by the present invention also provides a method for controlling the automatic deployment of a truck-mounted crane, including: in response to a deployment instruction, controlling the deployment of the truck-mounted crane from an initial state to a preset state according to a preset program; the preset state includes: Preset hook positions, preset turntable angles, preset boom lengths and preset boom amplitudes.

[0101] The deployment of the existing truck-mounted crane requires manual control by the operator, which is not only cumbersome to operate, but also prone to misoperation. However, the automatic deployment control method provided by the embodiments of the present invention uses a preset program for automatic control, which reduces the possibility of misoperation and improves the user experience of the device.

[0102] Further, preset programs include:

[0103] Control the hook to rise to the place where the weight is jacked up, that is, ...

Abstract

The invention relates to the technical field of automatic control of cranes, and discloses an automatic unfolding and folding control device of a lorry-mounted crane. The control device is based on aPLC chip, and the control device comprises a control command end which is used for receiving an unfolding or folding control command, a lifting arm telescopic control end which is used for outputtinga telescopic instruction for controlling a lifting arm to stretch and retract, a lifting arm variable-amplitude control end which is used for outputting a variable-amplitude instruction for controlling variable-amplitude of the lifting arm, a lifting hook lifting control end which is used for outputting a lifting instruction for controlling lifting of a lifting hook, and a rotary table rotary control end which is used for outputting a rotary instruction for controlling a rotary table to rotate, wherein the telescopic instruction, the variable-amplitude instruction, the lifting instruction andthe rotary instruction are automatically issued in response to the control commands according to a preset program. The invention discloses a unfolding method and folding method corresponding to the automatic unfolding and folding control device. According to the device, it is ensured that the lorry-mounted crane can be unfolded or folded safe and reliable, manual operation can be avoided, and misoperation can be reduced.

Description

technical field [0001] The present invention relates to the technical field of automatic control of cranes, in particular to a control device for automatically deploying and retracting a truck-mounted crane, a method for controlling the automatic deployment of a truck-mounted crane, a method for controlling the automatic folding of a truck-mounted crane, and a truck-mounted crane. Background technique [0002] The existing straight-arm truck-mounted cranes usually manually control the lifting of the hook, the telescoping of the boom, the luffing and landing of the boom, and the rotation of the turntable through a remote control or a hydraulic operating handle. for similar image 3 For the arranged truck-mounted crane, when the hook needs to be unfolded or retracted, the action space of the hook and in front of the cab is extremely limited. If the crane is not operated carefully, the hook will easily collide with other mechanisms or cargo boxes on the chassis. Causing crane s...
