Abstract

The invention discloses a sinking headframe double-layer sheave wheel platform system, comprising a headframe body I, a sheave wheel platform like the Chinese character mu, a headframe II, a sheave wheel platform like the Chinese character ri, a sheave wheel house, a short support I, a middle node, a corner node, a long support, a short support II and a short support III; and the upper part of the headframe body I is successively connected with the sheave wheel platform like the Chinese character mu, the headframe II, the sheave wheel platform like the Chinese character ri and the sheave wheel house. The sinking headframe double-layer sheave wheel platform system is composed of the sheave wheel platform like the Chinese character ri and the sheave wheel platform like the Chinese character mu. The arrangement equipment of the hoisting equipment of the headframe double-layer sheave wheel platform system is one time more than that of the monolayer sheave wheel platform headframe; two sets of high-speed main hosting equipment are arranged on the upper-layer sheave wheel platform like the Chinese character ri, which easily meets the safety requirement of pulleying height; two sets of auxiliary hoisting equipment and suspension load are arranged on the lower-layer sheave wheel platform like the Chinese character mu, which reduces the gravity center height of the overall headframe, and is more beneficial for overall stability and stress of the headframe.

Description

technical field [0001] The invention relates to a skywheel platform of a derrick, in particular to a double-layer skywheel platform of a mine vertical shaft sinking derrick. Background technique [0002] At present, the stereotyped derricks for shaft sinking in coal mines are divided into five types: I, II, III, IV, and V. These five types of derricks are all arranged in the form of a single-layer sky wheel platform, and each derrick can be arranged at most two sets at the same time. Lift equipment. With the development trend of large-scale mines, it is necessary to increase the number of lifting equipment in the sinking derrick to improve work efficiency. However, it is difficult to increase the number of lifting equipment for the traditional single-layer sky wheel platform due to the size limitation and the requirements of the process layout. Therefore, there is an urgent need to develop a new sky wheel platform system to arrange more lifting equipment to meet the needs ...
