Abstract

The invention discloses a rotary drilling rig mast anti-deflection device which comprises a mast and a turntable installed on the mast. The mast can deflect and rotate relative to the turntable, the two sides of the mast are respectively provided with a set of anti-deflection mechanisms, each set of anti-deflection mechanisms comprises an oil cylinder and a shaft lever, each oil cylinder is vertically arranged in the lateral direction of the mast, one end of each oil cylinder is connected to the mast, the shaft levers are arranged on the turntable and stretch out towards the other ends of the oil cylinders. When rock and soil exert transverse reacting force on the mast to enable the mast to have a tendency to rotate in drilling operation, the turntable exerts passive bearing reaction on the mast through the shaft levers to limit the mast to rotate. The anti-deflection device can guarantee that the mast cannot deflect when a rotary drilling rig drills a hole, and therefore it is guaranteed that drilling cannot deflect.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery drilling equipment, and in particular relates to a device for preventing a mast of a rotary drilling rig from deflecting and a rotary drilling rig with the same. Background technique [0002] Rotary drilling rig is a commonly used construction machine in the hole-forming operation of building foundation engineering. It is widely used in various foundation constructions such as cast-in-situ piles, continuous walls, and foundation reinforcement. It can be used in clay, silt, sand, hard clay, and frozen soil. The construction of various soil layers such as layer, rock layer, stroke bedrock, slightly weathered bedrock, etc. [0003] The core working components of the rotary drilling rig are the power head, drill pipe and drill bit, and the mast provides motion guidance, position adjustment and power transmission for these core working components, and bears various loads such as drilling ...
