Track-type crane and running mechanism thereof

A technology of running mechanism and crane, which is applied in the direction of walking mechanism, transportation and packaging, and load hanging components, etc. It can solve the problems such as the crushing of the curved rack of the traveling gear, the lack of climbing ability of the crane, and the poor positioning of the running wheel. To achieve the effect of preventing deflection operation, eliminating slipping phenomenon and reducing burden

Problems solved by technology

These two kinds of running mechanisms have the following disadvantages: the outer peripheral surface of the spoke of the running wheel is in direct line contact with the track, and the walking of the running wheel on the track is completely dependent on the friction between the outer peripheral surface of the spoke and the track, so the running wheel is in the process of starting and braking. It is easy to produce slipping phenomenon, so that the positioning of the running wheel is not good, so that the crane basically does not have the climbing ability
Although the walking mechanism can meet the climbing ability, it has the following defects: in the process of walking, the traveling gear is used as a transmission part on the one hand, and as a load-bearing running wheel on the other hand, so the traveling gear or the curved rack is easy to be compressed. Bad

Abstract

The invention relates to the field of cranes, and in particular relates to a track-type crane and a running mechanism of the track-type crane. The running mechanism of the rail-type crane comprises a transmission shaft, a running wheel fixedly arranged on the transmission shaft, and a track corresponding to the running wheel, wherein the running wheel comprises a wheel arm and a wheel flange, the transmission shaft or the wheel flange of the running wheel is provided with an outer gear ring, and the track is provided with a rack which is meshed with the outer gear ring. By adopting the running mechanism of the track-type crane, the crane not only has the climbing capacity, but also ensures that the outer gear ring and the rack are not easy to be damaged.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a rail-type crane and its operating mechanism. Background technique [0002] Such as Figure 1-2 As shown, the common single-rim track type running mechanism includes a running wheel 1 and a track 2, and the running wheel 1 includes a spoke 3 and a wheel rim 4 positioned at one end of the spoke 3; as Figure 3-4 As shown, the existing double-rim track type running mechanism includes a running wheel 11 and a track 12 , and the running wheel 11 includes a spoke 13 and a wheel rim 14 located at both ends of the spoke 13 . These two kinds of running mechanisms have the following disadvantages: the outer peripheral surface of the spoke of the running wheel is in direct line contact with the track, and the walking of the running wheel on the track is completely dependent on the friction between the outer peripheral surface of the spoke and the track, so the running wheel is in the process of star...
