Caterpillar band and walking device with caterpillar band

Abstract

The invention discloses a caterpillar band and a walking device with the caterpillar band. The caterpillar band comprises multiple forged and formed caterpillar band boards and hinge pins, wherein every two adjacent caterpillar band boards are in pivot joint through the corresponding hinge pin. Each caterpillar band board comprises two first boards and a connecting board connected with the two first boards and engaged with a gear. First pivot joint holes are formed in one side of each first board, second pivot joint holes are formed in the other side of each first board, a first pivot joint groove is formed between every two first pivot joint holes, and the interval between every two second pivot joint holes is a tooth groove where the gear is inserted. When two adjacent caterpillar band boards are in pivot joint, two corresponding second pivot joint holes are inserted in the corresponding first pivot joint groove and coaxial with the corresponding first pivot joint holes, and the twoadjacent caterpillar band boards are in pivot joint together through the first pivot joint holes and the second pivot joint holes in the two sides of the corresponding tooth groove via the corresponding hinge pins. By the adoption of the above structure, the overall structural strength of the caterpillar band can be improved, the service life of the caterpillar band can be prolonged, and the walking device with the caterpillar band can stably walk.

Description

technical field [0001] The invention relates to a crawler structure, in particular to a crawler with strong structural strength and stable running and a walking device with the crawler. Background technique [0002] A crawler walking device generally refers to a device that can walk on swamps or muddy grounds, such as a crawler excavator, which is a device used to walk in swamps or ponds and perform excavation actions. The track is driven by a driving wheel and is surrounded by a flexible link of the driving wheel, road wheel, induction wheel and supporting wheel; the track is composed of track shoes and track pins. The existing crawler has a layer of rubber layer on the outer surface, which can play the role of wear resistance and slip resistance. However, the rubber layer deforms and easily falls off when walking, and when walking on the ground with sharp debris such as gravel ground, it is easy to be stabbed by sharp objects. The wear and tear of the rubber layer after l...

AI Technical Summary

Problems solved by technology

The existing crawler has a layer of rubber layer on the outer surface, which can play the role of wear resistance and slip resistance. However, the rubber layer deforms and easily falls off when walking, and when walking on the ground with sharp debris such as gravel ground, it is easy to be stabbed by sharp objects. Broken, the rubber layer wears out after a long time walking, and the wear-resistant and slip-resistant function of the rubber layer is seriously lost, which reduces the overall structural strength and gripping ability of the track shoe, and reduces the service life.
