Problems solved by technology

Due to the mechanical limitation of the pipe rubbing machine itself, the efficiency of lowering the casing is very low, and the casing cannot be pulled out by itself, requiring an external power source, which makes the transition very troublesome and the construction efficiency is extremely low

Abstract

The invention discloses a drilling machine capable of pressing and pulling a protective case. The drilling machine capable of pressing and pulling the protective case comprises a platform (12) arranged on a crawler chassis (6), a deflection mechanism (8) arranged on the platform (12) in a hinged mode, a supporting rob (7) arranged on the deflection mechanism (8), a mast (9) hinged on the deflection mechanism (8), a winch (10) arranged on the mast (9), a vertical mast oil cylinder (11) hinged between the mast (9) and the deflection mechanism (8), a crane (1) arranged at the top end of the mast (9), a power head (3) arranged on the mast (9) in a sliding mode, a supporting platform (4) arranged at the lower end of the mast (9), a pulling oil cylinder (5) arranged between the supporting platform (4) and the power head (3), and a pressing wire rope and a pulling wire rope (2) which are winded on the winch (10). The drilling machine capable of pressing and pulling the protective case solves the construction problem of pressing and pulling the protective case with a big diameter and great depth, and construction efficiency of the protective case is improved greatly.

Description

technical field [0001] The invention relates to pile foundation construction equipment, in particular to a construction equipment for quickly pressing and pulling out casings that can be used in conjunction with a rotary drilling rig for simultaneous construction. Background technique [0002] In the pile foundation construction process, the construction of casings with large diameters and large depths is often encountered. At present, the lower casing equipment is mainly a rotary drilling rig and a professional lower casing drilling rig. The rotary drilling rig can handle the casing construction with small diameter and small depth, while the casing construction with large diameter and deep depth requires professional casing drilling rigs, such as pipe rubbing machines. Due to the mechanical limitation of the pipe rubbing machine itself, the efficiency of lowering the casing is very low, and the casing cannot be pulled out by itself, requiring an external power source, whic...
