Problems solved by technology

When it walks on the bumpy ground, it is easy for the supporting wheel to break away from the track shoe teeth. When the supporting wheel derails and then touches the track shoe again, it is difficult to engage with the track shoe tooth again, causing the track roller to rotate and collide with the surface of the track shoe. Tooth gnawing affects the operation of crawler cranes

Embodiment 1

[0028] Please refer to figure 1 , this embodiment provides a crawler walking device, which can be applied to crawler cranes. Crawler cranes usually work on soft ground and uneven surfaces. After the roller 1 is detached from the track shoe 4, when it returns to the track shoe 4, it is not easy to engage with the gear teeth again. When the roller 1 rotates, the surface of the roller 1 collides with the surface of the track shoe 4, resulting in tooth gnawing . Coupled with actions such as crawler crane steering, the tooth gnawing phenomenon will be more serious.

[0029] In order to avoid the accidental derailment of the track roller 1 and serious tooth gnawing of the track shoes 4, and improve the service life of the track shoes 4, the present invention proposes to add a structure of the guide wheel 3, and the track roller 1 can be separated from the track by the settlement of the guide wheel 3 Behind the 4 teeth of the plate, there is also the guide wheel 3 that is always at...

Embodiment 2

[0050] The embodiment of the present invention also discloses a crawler crane, which includes a crane body and two crawler running devices of the above-mentioned embodiments. Crawler crane walking operation.

[0051] The crawler crane includes the same structure and beneficial effect as the crawler traveling device in the foregoing embodiments. The structure and beneficial effects of the crawler traveling device have been described in detail in the foregoing embodiments, and will not be repeated here.

Abstract

The invention provides a crawler traveling device and a crawler crane, belonging to the technical field of cranes, comprising a crawler frame and crawler shoes surrounding the crawler frame, drive wheels are respectively provided at both ends of the crawler frame, and multiple a supporting wheel, the driving wheel and a plurality of the supporting wheels are respectively engaged with the teeth of the track shoe, and at least one guide wheel is included, and the guide wheel is engaged with the teeth of the track shoe , and the guide wheel and the supporting wheel are hinged. By hinged a guide wheel on the track roller, when the track roller breaks away from the teeth of the track shoe, the guide wheel will swing down due to its own gravity, and still maintain good contact with the track shoe, and fit the track shoe tooth ;Because the guide wheel plays a very good guiding role, the supporting wheel can fit the track shoe teeth well without gnawing. In this way, the phenomenon of tooth gnawing is avoided, and at the same time, the wear of the track shoes can be slowed down.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crawler traveling device and a crawler crane. Background technique [0002] Tracks are driven by flexible links surrounding the drive pulley, road wheels, idlers and track rollers. The track is composed of track shoes and track pins. The track pins connect the track shoes to form a track link. There are holes at both ends of the track shoe, which are engaged with the driving wheel. There are inducing teeth in the middle, which are used to straighten the track and prevent the track from falling off when the tank turns or rolls. ) to improve the firmness of the track shoe and the adhesion between the track and the ground. [0003] Crawler crane is a mobile crane that installs the lifting operation part on the crawler chassis and relies on the crawler device for walking. Crawler cranes usually work on soft ground and uneven surfaces. When it walks on the bumpy ground, it is eas...
