Crawler-type dynamic compactor and gooseneck boom device thereof

Abstract

The invention discloses a gooseneck boom device. The gooseneck boom device is characterized in that a frame-type gooseneck structure is adopted to replace a conventional gooseneck structure evoluted from a crawler-type crane, and bionics design and split design are integrated in design conception, so that a gooseneck boom and a jib structure are more attractive in appearance, and the gooseneck boom device is convenient to mount, demount and transport; stress and force transmitting states of the structure are analyzed and optimized during designing, so that the gooseneck boom device is clear in structural hierarchy and convenient to manufacture, mount and maintain; and the gooseneck structure under a loaded condition is more excellent in strength, stability and fatigue resistance, so that service lives of the gooseneck boom, even the whole vehicle, are prolonged. The invention further discloses a crawler-type dynamic compactor applying the gooseneck boom structure.

Description

technical field [0001] The invention relates to the structural design of a crawler-type construction machinery in the technical field, especially for the design of the hoisting structure of construction machinery under high working strength, high working frequency and harsh working conditions, and in particular to a crawler-type dynamic compaction machine and its goose head device. Background technique [0002] In recent years, my country's infrastructure construction market has begun to accelerate growth. The dynamic compaction construction method has been developed and applied to landfills, desert foundations, land reclamation, soft soil reinforcement, and hardening of airport runways in terms of engineering construction and environmental protection coordination; The United States also applies it to the research of nuclear waste disposal sites. Due to the reasonable and effective application of dynamic compaction construction technology in these projects, the construction ...

AI Technical Summary

Problems solved by technology

[0012] It can be seen that the structure of the goose head plays a very important role in the process of force transmission. Since the tamping energy of the dynamic compaction machine is relatively large, the plate-type goose head continues to use the goose head structure of the crawler crane. Under the condition of high working frequency and high working intensity, the plate-type goose head structure is difficult to meet the requirements of the dynamic compaction machine for the strength, stiffness and stability of the goose head structure, which affects the safety and service life of the whole vehicle
