Description

Technical Field

[0001] The utility model relates to the field of impact pipes, in particular to a well point hole forming impact pipe. Background Art

[0002] An impact drill is an engineering drilling rig that uses the impact force of a drill bit to punch and drill holes in rock formations. The specific principle is: when using an impact drill, an electric motor drives a crank and a connecting rod through a gear transmission, causing a compressed air piston to reciprocate in an impact piston cylinder. The compressed gas pushes the impact piston cylinder hammer to strike the tail end of the tool at a higher impact frequency, causing the tool to punch downward to form a hole. Existing impact tubes cannot be extended, and the structure of the impact tubes that can be extended is too easy to break and detach. At the same time, the impact tube is not fixedly connected to the support tube, so it is relatively loose and will shake during the impact process, which may affect the verticality of the hole after the impact. Therefore, a well point hole impact tube is proposed. Utility Model Content
