Drilling rig equipment and methods for hoisting and lowering reinforcement cages

Abstract

The drilling rig equipment includes the turntable, the connector set on the turntable, the left mast oil cylinder, the right mast oil cylinder, the turntable, the mast, the main hoist, the anchor bracket assembly, the main hoist wire rope, the auxiliary hoist wire rope and the auxiliary hoist; The body is connected to the turntable, and the two ends of the left mast oil cylinder and the right mast oil cylinder are respectively hinged on the connecting body and the mast; the turntable is hinged to the connecting body, and the turntable can rotate up and down around the connecting body; Driven by the right mast oil cylinder, it can rotate left and right around the turntable; the anchor frame assembly includes the first pulley frame and the second pulley frame; the first pulley frame and the second pulley frame are set at an acute angle θ; the auxiliary hoisting wire rope Wound on the first pulley frame and connected with the auxiliary winch, the main hoisting wire rope is wound on the second pulley frame and connected with the main winch. Drilling rig equipment can complete the drilling and lifting of cast-in-situ piles, and lowering of reinforcement cages, with high construction efficiency. The invention also relates to a method for hoisting and lowering the reinforcement cage.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a drilling rig equipment and a method for hoisting and lowering a reinforcement cage. Background technique [0002] In recent years, with the rapid development of the domestic economy, the urban construction and redevelopment projects of large and medium-sized cities, the reconstruction of old urban areas, subway tunnels, underground enclosure structures, bridge reconstruction and expansion projects, etc. The foundation hole forming equipment is used for the construction of the pile foundation. [0003] Because the compressive strength of concrete is high but the tensile strength is very low, it is necessary to lower the reinforced cage in advance into the pile hole and then insert the conduit for concrete pouring to improve the tensile effect. Reinforcement cage refers to the collective name of the reinforced structure that needs to be prefabricated, such as bored...

AI Technical Summary

Problems solved by technology

[0004] To sum up, it can be seen that during the whole process of cast-in-place piles, two large-scale machines, the rotary drilling rig and the crane, need to work together to complete the construction. After the drilling of the rotary drilling rig is completed, the rotary drilling rig must be withdrawn and replaced with a crane to lift the reinforcement cage. , Decentralization, and installation work, the entire construction process is time-consuming, low in effect and high in cost
