M-shaped support system of derrick for sheave platform shaped like a Chinese character mu

Abstract

The invention discloses an M-shaped support system of a derrick for a sheave platform shaped like a Chinese character mu, comprising a node I, a reversed V-shaped support, a node II, a small horizontal support, a small vertical support, a node III, a trapezoidal support, an M-shaped support I, a sheave platform shaped like a Chinese character mu, a small trapezoidal support body, a sheave platform shaped like a Chinese character ri, a sheave room, a node IV, an M-shaped support II, a large crossbeam, a node V and a node VI, etc. The trapezoidal support, the large crossbeam and the node III are connected into a trapezoid; the lower end of the M-shaped support I on the large crossbeam is connected with the node III, and the upper end is connected with the node III; the M-shaped support II, the node V, the M-shaped support II, the node IV, the M-shaped support I and the node III are connected in sequence into the M-shaped support system. Adopting the M-shaped support system, the derrick for the sheave platform can be stressed reasonably. Compared with the traditional reversed V-shaped support system, the M-shaped support system can reduce the span of the beam of the sheave platform and well control the size and the deformation of the section of the beam of the sheave platform.

Description

technical field [0001] The invention relates to a supporting system, in particular to an "M" supporting system suitable for an "M"-shaped skywheel platform of a shaft sinking derrick in a coal mine. Background technique [0002] At present, the stereotyped derricks for sinking shafts in coal mines are divided into five types: I, II, III, IV, and V. The sky wheel platform beams of these five types of derricks all adopt the plane layout of "day" shape, and the support system adopts " Herringbone-shaped facade layout. With the development trend of large-scale mines, in large-scale sinking derricks, due to the increase in the size of the sky wheel platform and the requirements of the lifting process, the beam of the sky wheel platform sometimes needs to be arranged in the shape of a "mesh". Adopting the "herringbone"-shaped facade support system will inevitably make the beam nodes of the sky wheel platform and the fulcrum of the support system misaligned, resulting in uneven st...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and solve the problem that the derrick sky wheel platform adopts a "mesh"-shaped plane layout, and the beam nodes of the sky wheel platform do not coincide with the fulcrums of the support system, so that the force on the derrick system is uneven, and the sky wheel platform beam For the problem of excessive internal force, provide an M-shaped derrick support system for the mesh-shaped sky wheel platform
