Crawler travel device

Abstract

The invention discloses a crawler travel device. The crawler travel device comprises a supporting frame, a belt wheel unit and a walking caterpillar which is wound around the belt wheel unit; the walking caterpillar is provided with a plurality of caterpillar teeth which are distributed at intervals; tooth grooves are formed between adjacent caterpillar teeth; a silt removing section is arranged at the upper part of the walking caterpillar; a silt removing device for removing silt in the tooth grooves of the silt removing section is mounted on the supporting frame; the silt removing device comprises an endless belt and a driving assembly for driving the endless belt to run along a circular track; the endless belt is provided with a straight section which is located above the silt removingsection; an included angle of 0-90 degrees is formed between the running direction of the straight section and the running direction of the silt removing section; the component velocity of the runningvelocity of the straight section in the running direction of the silt removing section is equal to the running velocity of the silt removing section; and one or more silt removing cutters which passthrough the tooth grooves when moving along the straight section to scrape the silt in the tooth grooves are mounted on the endless belt. The crawler travel device has the advantages of being simple in structure, easy to manufacture, low in cost, good in silt removing effect, low in energy consumption, stable and reliable to work, and the like.

Description

technical field [0001] The invention relates to the technical field of crawler walking equipment, in particular to a crawler walking device. Background technique [0002] During the walking process of the crawler walking device, the walking crawler will contact the ground soil to a certain degree of adhesion behavior. If the continuously adhered soil is not removed in time, it will slowly accumulate and be subjected to repeated pressure by continuously revolving around the contact surface between the crawler belt and the substrate. It is reinforced by pressure, so as to gradually fill the gap between the high teeth of the track shoe, and reduce the actual height of the track shoe, which will lead to a decrease in the friction between the walking track and the ground, and the phenomenon of not getting old grip and slipping, which is serious Affect the passing capacity, operation quality and work efficiency of the crawler walking device. Therefore, it is necessary to remove t...

Problems solved by technology

[0004] 1. It is simple, practical and reliable to use external forces such as gas and liquid to perform impact desilting, but in the application process, there are disadvantages such as high positioning requirements, sufficient impact pressure requirements, and high energy consumption, and it is suitable for underwater (in liquid) working environments. It is said that due to the great water resistance, the effective impact force will be greatly weakened, so there are big problems in engineering applications, and only theoretical suggestions have been put forward at present.

[0005] 2. Using the method of vibration to remove mud not only requires a large impact force, but also requires a large amplitude to adhere to the track, which is contradictory to the tensioning of the work vehicle and the track itself, and is not practical, and The adhesion force of the soft bottom of the seabed and other geology is very strong, and ordinary vibration cannot make the adhered sea mud detach at all.

[0006] 3. Surface engineering is used to remove mud by treating the contact surface or changing its shape, such as using a hard brush, which can improve the degree of adhesion and reduce the adhesion force to a certain extent, but this change is very weak , it has almost no effect on the sea mud and other substrates with strong adhesion, and the crawler running mechanism of the work vehicle is very simple and optimized, and it is not suitable for changing the shape structure to a large extent, so this method is not applicable
