Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] refer to figure 1 , figure 1 The automatic identification method of the present invention is a flow chart of the steps of the embodiment, which is used to prevent the luffing cylinder of the crane from colliding with the body, including the following steps:

[0024] Step S110, detecting the angle formed by the boom of the crane and the predetermined position, and detecting the rotation angle of the turntable of the crane;

[0025] Step S120, determining the position of the luffing cylinder of the crane according to the angle between the boom of the crane and the predetermined position and the rotation angle of the turntable of the crane;

[0026] Step S130, if the luffing cylinder is lo...

Abstract

The invention discloses an automatic identification method, an automatic identification device and a crane. The automatic identification method is used for preventing a variable-amplitude cylinder of the crane from colliding with a crane body, and comprises the steps as follows: detecting the angle formed by a large arm of the crane and a preset position, and detecting the rotation angle of a rotary table of the crane; determining the position of the variable-amplitude cylinder of the crane via the angle formed by the large arm of the crane and the preset position and the rotation angle of the rotary table of the crane; if the variable-amplitude cylinder is positioned in a dangerous space in which the variable-amplitude cylinder is likely to collide with the crane body, sending out a control signal which is used for preventing collision of the variable-amplitude cylinder with the crane body. According to the invention, safety problems about damage to the equipment and the like due to collision of the variable-amplitude cylinder with the crane body in the operation process of the crane are solved, and the operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an automatic identification method, an automatic identification device and a crane. Background technique [0002] For crane equipment, especially for off-road cranes, it is difficult to ensure that all covering parts such as walking platform, engine cover and fender are limited by the size of the parts on a lower plane. Therefore, when the crane performs operations such as luffing, turning left, turning right, etc., the luffing cylinder may collide with the protruding body, damage the equipment, and cause serious safety accidents. Contents of the invention [0003] In view of this, the present invention proposes an automatic identification method, an automatic identification device and a crane, so as to avoid collision between the luffing oil cylinder and the machine body during the operation of the crane. [0004] On the one hand, the present invention provides an automatic id...
