Telescoping Mechanism of Vibrating Crushed Stone Pile Machine

Abstract

The invention discloses a telescopic mechanism of a vibro-replacement stone column machine. The telescopic mechanism comprises a lower telescopic assembly and an upper telescopic assembly. The lower telescopic assembly comprises a plurality of first casing pipes connected successively from inside to outside in a sleeving manner, the first casing pipes comprise a first inner casing pipe, N first middle casing pipes and a first outer casing pipe, and a tray is coaxially and fixedly connected to the bottom end of the first inner casing pipe; the upper telescopic assembly comprises a plurality of second casing pipes connected successively from inside to outside in a sleeving manner, and the bottom end of the second outer casing pipe is connected to a flange at the top end of the first outer casing pipe, so that the upper telescopic assembly is fixedly arranged above the lower telescopic assembly; lengths of the first and second casing pipes are arranged such that when the lower telescopic assembly stretches to the longest, the upper telescopic assembly stretches to the longest, and the (i+1)th second casing pipe from outside to inside is partially located in the ith first casing pipe from outside to inside. The telescopic mechanism has the beneficial effect of increasing the radial thickness of the whole telescopic mechanism which is stretched so as to enhance the stability of the telescopic mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment. More specifically, the present invention relates to a telescoping mechanism of a vibro-crushing pile machine. Background technique [0002] In recent years, with the development of engineering construction, especially the development of reclamation projects, and the high standard of environmental protection requirements, there is an increasing demand for vibrating technology for soils with undrained shear strength less than 20kPa. Under the condition of shallow vibrating within 20 meters, a single guide rod (conduit) can be used to achieve the engineering purpose. For 30-40 meters deep vibrating, the use of large equipment can also be achieved with a single extended guide rod. The purpose of the project is that the project cost will be greatly increased. When the hole depth is more than 50 meters, if you continue to use a single guide rod, not only the project cost will be unbearabl...

Problems solved by technology

Under the condition of shallow vibrating within 20 meters, a single guide rod (conduit) can be used to achieve the engineering purpose. For 30-40 meters deep vibrating, the use of large equipment can also be achieved with a single extended guide rod. The purpose of the project is that the project cost will be greatly increased. When the hole depth is more than 50 meters, if you continue to use a single guide rod, not only the project cost will be unbearable, but also the safety hazard will increase sharply. The only feasible solution is to use the telescopic tube technology to complete the established Depth Vibration Stone Pile
