Track frame telescopic detection device and track frame

Abstract

The invention provides a track frame telescopic detection device and a track frame, and belongs to the technical field of engineering machinery, and the track frame telescopic detection device comprises: a first detection structure and a second detection structure which are arranged in a staggered manner along the horizontal direction or the vertical direction; and a trigger structure which comprises a first trigger part, a second trigger part and a third trigger part. The first detection structure and the second detection structure are provided with a first position where the first trigger part is matched with the first detection structure and the second trigger part is matched with the second detection structure, and a second position where the first trigger part and the first detection structure are arranged in a staggered mode and the third trigger part is matched with the second detection structure. According to the track frame telescopic detection device, the first position and the second position of the track frame can be distinguished through the different matching states of the first detection structure and the second detection structure and the first triggering part the second triggering part and the third triggering part, and the distinguishing mode is accurate; and misjudgment of the first position and the second position is avoided.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crawler frame telescopic detection device and a crawler frame. Background technique [0002] Crawler construction machinery refers to construction machinery that uses crawlers to walk. The crawler has a large ground area, good passability, strong adaptability, and can walk with a load. In order to save transportation costs and work in limited space, crawler construction machinery has the function of stretchable track frame. However, it is not easy to accurately control the degree of stretching of the track frame during the adjustment process, resulting in frequent occurrences of track frame adjustments that are not in place, affecting normal operation. Do your homework. [0003] Chinese patent document CN212950890U discloses a crawler frame. Three trigger groups are set between the frame body and the crawler frame. During the movement of the crawler frame relati...
