Rig equipment and method of hoisting and lowering reinforcement cage

Abstract

The invention discloses rig equipment. The rig equipment comprises a rotary table, a connecting body, a left mast oil cylinder, a right mast oil cylinder, a turnplate, a mast, a main winch, a hoistinganchor frame assembly, a main winch steel wire rope, an auxiliary winch steel wire rope and an auxiliary winch arranged on the rotary table; the connecting body is connected on the rotary table, twoends of the left mast oil cylinder and the right mast oil cylinder are respectively hinged to the connecting body and the mast, the turnplate is hinged to the connecting body, and can rotate up and down around the connecting body; the mast is hinged to the turnplate, and the mast can rotate left and right around the turnplate driven by the left mast oil cylinder and the right mast oil cylinder; the hoisting anchor frame assembly comprises a first pulley frame and a second pulley frame; the first pulley frame and the second pulley frame are arranged with an acute angle of theta; the auxiliary winch steel wire rope is wound on the first pulley frame and connected with the auxiliary winch, and the main winch steel wire rope is wound on the second pulley frame and connected with the main winch. The rig equipment can complete drilling, hoisting and lowering of a reinforcement cage of a cast-in-place pile, and the construction efficiency is high. The invention further relates to a method forlifting 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
