Abstract

The invention discloses a traveling posture control method of a crawler crane. The method comprises the following steps: connecting a control handle in a hinged mode to a hinged point of a control console of the crawler crane, so that the control handle can rotate on a vertical plane and a horizontal plane by taking the hinged point as the center, and the projection A of an operating end of the control handle on the horizontal plane can move on the horizontal plane and is kept on the circumference which takes the hinged point as the center of a circle and takes the Rmax as a radius and on any inner position thereof; detecting the position of the control handle; controlling the traveling directions and traveling speeds of a left crawler and a right crawler of the crawler crane according to the position of the control handle. The invention also discloses a traveling posture control device and a crawler crane. According to the technical scheme, the condition in the prior art that traveling of the left crawler and the travelling of the right crawler of the crawler crane are respectively controlled by increasing pedals can be avoided, traveling of the crawler crane can be controlled through one control handle only, the cost and operating complexity are reduced, the misoperation condition is avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a walking posture control method of a crawler crane, a walking posture control system and a crawler crane. Background technique [0002] At present, on crawler cranes, the application of electronic control systems is becoming more and more extensive, and the technology is becoming more and more mature and reliable. However, crawler cranes generally require two operating levers or operating handles to control the walking. When walking and boarding are required to perform simultaneous actions, there are lifting or other motion controls for left and right walking and boarding. When it is necessary to control more than three actions, the operator's hands are difficult to cope with, so some manufacturers control the walking of the crawler by adding pedals, and use the handle to operate the lifting and turning of the winch on the car. It not only increases the complexity of the st...
