Embodiment Construction

[0027] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0028] In the present invention, considering that the original fixed pressure plate cannot rotate or roll with the movement of the crawler shoe, it will produce rigid sliding friction with the crawler shoe, resulting in the crawler shoe and the crawler frame welded with the fixed pressure plate. Serious wear and tear that cannot be repaired. Therefore, in the present invention, the structure that the pressure plate cannot rotate or roll with the movement of the track shoe is changed, and the rolling friction structure that can rotate or roll is used to replace the existing fixed pressure plate.

[0029] In an embodiment of the present invention, the crawler chassis includes a crawler frame, a driving wheel installed at the end of the crawler frame, a plurality of rollers installed at the bottom of the crawler frame, and surround...

Abstract

The invention relates to a cater-pillar track chassis, which comprises a cater-pillar track frame, a driving wheel mounted at one end part of the cater-pillar track frame, a plurality of thrust wheels mounted at the bottom part of the cater-pillar track frame, and a cater-pillar track plate wrapping the driving wheel, the plurality of thrust wheels and the cater-pillar track frame, wherein a rolling friction mechanism capable of rolling along with the moving cater-pillar track plate is arranged between the driving wheel and the farthest thrust wheel which is the closest to the driving wheel. The invention further relates to a caterpillar crane with the cater-pillar track chassis. According to the invention, the rolling friction mechanism is arranged between the driving wheel and the farthest thrust wheel and can roll along with the moving cater-pillar track, thereby playing a role of propping against the cater-pillar track plate in space between the driving wheel and the farthest thrust wheel, preventing a phenomenon of tooth gnawing, and changing the original main sliding friction way into a main rolling friction way, which can effectively avoid more serious abrasion generated between the cater-pillar track frame and the cater-pillar track plate.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a crawler chassis and a crawler crane. Background technique [0002] With the continuous development of crawler cranes, various structural arrangements and functions to be realized of crawler cranes are becoming more and more refined, and more and more attention is paid to detailed design. [0003] In the design of the track frame, it may be necessary to reduce the distance of the grounding rollers at the farthest ends of the grounding rollers for various special reasons, such as reducing the driving force for walking and turning. However, at the same time, the structural design may also have certain special requirements. For example, when the unilateral double drive is used to set the traveling reducer at the front and rear ends, the installation and arrangement of the movable drive frame with the tensioning function will cause the drive wheel to be unable to The...
