Embodiment Construction

[0044] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0045] According to one aspect of the present invention, a gantry crane omnidirectional steering device is provided, see figure 1 , including: a walking beam 1, a walking steering mechanism 2 arranged at both ends of the walking beam 1, and a jacking mechanism 3 arranged in the middle of the walking beam 1. The walking beam 1 is arranged at the lower end of the outrigger of the gantry crane, and is used for supporting the gantry crane. The structure and shape of the walking beam 1 are designed according to the actual situation, and the present invention does not specifically limit it. For example, the walking beam 1 is a structural member made of tailor-welded plates, which is a truss type or a ...

Abstract

The invention discloses a gantry crane all-dimensional steering device and method. The device comprises walking beams arranged at the lower ends of gantry crane supporting legs, a walking steering mechanism arranged at the two ends of the walking beams, and a jacking mechanism arranged between the walking beams; and the walking steering mechanism comprises a walking wheel train, a walking table frame and a rotating mechanism. By means of the jacking mechanism, the walking beams can be jacked up or lowered, so that the walking wheel train can be suspended; and by means of the rotating mechanism, the movement direction of the walking wheel train can be changed, so that a gantry crane on the walking beams can achieve all-dimensional steering, and therefore the using range of the operation environment of a hoisting device is widened. In addition, the rotating mechanism comprises a rotating bearing, a rotating driving motor and a gear; and the rotating bearing is driven by the rotating driving motor and the gear to rotate, the movement direction of the walking wheel train can be accurately controlled, and the hoisting operation precision is improved. According to the gantry crane all-dimensional steering device and method, all-dimensional steering can be achieved, the operation accuracy and the operation precision are high, the application range is wide, and cost is low.

Description

technical field [0001] The invention relates to the technical field of mobile gantry crane steering, in particular to a gantry crane omnidirectional steering device and method. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Today's large-scale mobile gantry crane technology is relatively mature in China. Large-scale mobile gantry cranes have large dimensions and generally adopt rail-type and tire-type movement methods. It is difficult for them to achieve all-round steering, and there have been no relevant reports. The domestic mobile gantry crane device does not have the function of omnidirectional steering. [0004] At present, the tire-type gantry crane device can complete the steering from one position to another in an arc, but it not only requires a large space for the steering to be in place, but also ne...
