Multifunctional micropile drilling machine

Abstract

The invention discloses a multifunctional micropile drilling machine, comprising a base plate, a platform which is fixed on the base plate, a covering element and an amplitude variation mechanism which are arranged on the platform, and a drilling and lifting device which is connected with the amplitude variation mechanism, wherein a hydraulic system and a main control system are arranged in the covering element; the amplitude variation mechanism comprises a turning pair A and a turning pair B; the turning pair A drives the amplitude variation mechanism and the drilling and lifting device to rotate relatively to the platform by + / - 90 degrees; and the turning pair B drives the drilling and lifting device to rotate relatively to the amplitude variation mechanism by 360 degrees. The turning pair A of the multifunctional micropile drilling machine does not turn along with the platform and just drives the amplitude variation mechanism and the drilling and lifting device to turn, so that the turning moment is reduced and turning becomes quite steady; the turning pairs employed also are lower than the turning pair employed to drive the whole platform in power so that the cost is saved; the turning pair B is capable of rotating by 360 degrees; and in contrast with the similar drilling machine employing an oil cylinder for rotation, the multifunctional micropile drilling machine has the advantages that the rotation angle is large and positioning of drilling is also quite accurate.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a multifunctional micro-pile drilling rig capable of anchoring, micro-pile, rotary spraying and other engineering constructions. Background technique [0002] The construction of multi-functional micro-pile drilling rig is an important branch of the foundation construction industry. It has relatively mature technology and stable market abroad, and is evolved from European construction technology. This type of equipment is mainly used for micro-pile drilling, anchoring slope protection construction, anti-slope, tunnel wall protection, high-pressure rotary spraying, etc., and can be applied to foundation construction, deep foundation pit construction, mine construction, water conservancy construction and tunnel construction and other fields. With the continuous updating of construction technology and the continuous improvement of customer requirements, the control system and structural design of t...

AI Technical Summary

Problems solved by technology

With the continuous updating of construction technology and the continuous improvement of customer requirements, the control system and structural design of the micro-pile drilling rig are constantly being optimized, and the functions are constantly expanding. In addition to meeting the original micro-pile process, a new down-the-hole hammer method has been added. , anchoring slope protection deep foundation pit construction method, tunnel rock drilling method, rotary grouting method, etc., but the micro-pile drilling rig still has certain defects in the rotary flexibility performance, which needs to be further solved
