Embodiment Construction

[0051] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] It should be noted that concepts such as "first" and "second" mentioned in this disclosure are only used to distinguish different nouns, devices, modules or units, and are not used to limit the implementation of these nouns, devices, modules or units. The sequence or interdependence of functions.

[0053] The vehicle crane is a kind of crane installed on the chassis of ordinary vehicles or special vehicles, and consists of two parts: getting on the car and getting off the car. The performance of the off-board chassis is equivalent to that of a load-carrying vehicle with the same total weight of the whole vehicle, and it can be driven on the road. The...

Abstract

The invention relates to a vehicle crane control method and device, and a vehicle crane. The method comprises the following steps of determining a voltage target value according to a received input signal for starting a crane from a control handle; determining an intermediate voltage value according to a first voltage value and the voltage target value; and when each signal output time point of afirst control time period is reached, determining and outputting a first output voltage corresponding to the signal output time point, wherein the first output voltage at a first target time point isthe intermediate voltage value, the first output voltage of a time end point of a first control time period is a voltage target value, and in the first time period formed by a time starting point of the first control time period and the first target time point, an increasing amplitude of the first output voltage corresponding to a latter signal output time point is increased along with the increase of time compared with the increasing amplitude of the first output voltage corresponding to a former signal output time point. Therefore, good micro-motion performance is achieved on control of thecrane, and large shaking in a starting process is prevented.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, relates to a control method and device for a vehicle crane and a vehicle crane. Background technique [0002] The vehicle crane is a kind of crane installed on the chassis of ordinary vehicles or special vehicles, and consists of two parts: getting on the car and getting off the car. The performance of the off-board chassis is equivalent to that of a load-carrying vehicle with the same total weight of the whole vehicle, and it can be driven on the road. The car is a kind of machine that does cyclical and intermittent movements. It uses the pick-up device to lift the item from the pick-up place, and then moves the object to the designated place and lowers it. The movement of the vehicle crane on the vehicle includes four main actions: boom luffing, boom telescoping, turntable rotation, and winch retraction. During the operation, the operator is located in the operating room wh...
