Abstract

The invention relates to a sinking tubular steel derrick and a mounting method thereof. The sinking tubular steel derrick is of a flat top rectangular pyramid with a holohedral main body truss and comprises a main support rod piece, support rod pieces corresponding to three layers of platforms, namely a sheave wheel platform, an intermediate platform and a gangue turning platform, which are connected with the main support rod piece from top to bottom, and the like. Beams of the sheave wheel platform arranged in the shape of a Chinese character Ri; the support rod pieces of the sheave wheel platform are arranged in the shape of inverted V and connected with central nodes on the four sides of the sheave wheel platform and nodes at four corners of the intermediate platform; and the axial lines of the support rod pieces of the intermediate platform are in superposition with the extension lines of the axial lines of the support rod pieces of the gangue turning platform, and the support rod pieces of the intermediate platform are arranged in the shape of the inverted V and used for connecting the intersection points between the central nodes on the four sides of the intermediate platform, the main support rod piece and a derrick foundation. The derrick is suitable for vertical shafts with net diameter of 6.5m-9m, average depth of not more than 1400m and working load of the derrick of not more than 530t and second-stage engineering construction thereof, and can simplify processing, transportation, mounting and detachment, realize stronger applicability to terrain and provide reliable guarantee for realizing rapid construction and shortening construction period.

Description

technical field [0001] The invention relates to the field of shaft engineering construction, in particular to a shaft sinking steel pipe derrick suitable for shaft shafts with a net diameter of 6.5m to 9m, an average depth of ≤1400m, and a derrick working load of ≤530t and its second-phase construction and an installation method thereof. Background technique [0002] Sinking steel pipe derricks in my country's industry standards are divided into five categories and seven models, with a maximum (Type V sinking steel pipe derrick) working load of 427t and a broken rope load of 1067t, and can construct shaft projects with a maximum net diameter of 8m and a depth of ≤1000m; Due to structural limitations of the derrick, the derrick rods at corresponding positions are not interchangeable, the assembly direction is single, and the hoisting length of a single piece is too large (18.05m), which makes on-site installation difficult and poses a great safety hazard. [0003] In recent ye...
