Problems solved by technology

[0004] At present, there are two types of cast track shoes used in crawler cranes. One is the structure with teeth in the middle. The track shoes of this structure have a large impact and are not stable when running; the other is formed by two connected track shoes. Grooves, and contact force transmission with the drive wheel through the arc-shaped support plate. Track shoes with this structure are prone to crushing on both sides of the drive wheel, and the track shoes cannot be perfectly meshed with the drive wheel. Therefore, there are also large impacts, unsteady defect

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The concrete structure of novel crawler shoe of the present invention is as figure 1 shown. It can be seen from the figure that the track shoe 1 includes a bottom plate 107 , an engaging block 109 , a connecting pin lug 106 , a supporting block 105 and a guiding block 108 . Wherein, coupling lug 106 is fixed on both sides of bottom plate 107, and engagement piece 109 is arranged on the middle part of bottom plate 107, and it is used for engaging with the drive wheel of crawler crane, thereby carries out the transmission of force, to promote the motion of crawler crane. The support block 105 is arranged on the bottom plate 107 and is located on both sides of the engaging block 109, which is used to contact with the supporting wheels of the crawler crane, so as to bear the weight of the entire crawler crane and the working load thereon. The guide block...

Abstract

The invention provides a novel track plate comprising a soleplate, coupled pin ears, an engaging block, supporting blocks and a guiding block. The coupled pin ears are respectively fixed at both sides of the soleplate, the engaging block is arranged in the middle of the soleplate, the supporting blocks are arranged at both sides of the engaging block on the soleplate, the guiding block is arranged at one end of the supporting block close to the engaging block which is provided with an arc top, both side outlines of the engaging block are symmetrically arranged and formed by straight lines and curves from top to bottom, the upper surface of the guiding block is a plane, and both sides of the upper surface of the guiding block are respectively connected with an inclined surface. A reasonable track plate engaging surface is designed by utilizing a gear and rack engagement principle so as to better realize the matched force transferring between the track plate and a driving wheel. By designing guiding structures at both sides, the track plate can automatically adjust directions in the travel process so as to avoid an off-tracking phenomenon of a track.

Description

technical field [0001] The invention relates to a crawler shoe used in a running device of an engineering vehicle, in particular to a new crawler shoe used in a crawler crane. Background technique [0002] Crawler cranes often need to walk with a load in engineering construction operations, and the running stability of the traveling device is an important guarantee for the safe operation of crawler cranes. [0003] As one of the key components in the crawler walking device, the track shoe is an important carrier to realize the conversion of the driving force of the traveling motor into the forward power of the whole machine. Therefore, the correct meshing of the track shoe and the drive wheel and the reasonable transmission of force are the keys to realize the smooth operation of the track running device. [0004] At present, there are two types of cast track shoes used in crawler cranes. One is the structure with teeth in the middle. The track shoes of this structure have ...
