Formwork device for constructing inclined shaft working surface in coal mine

Abstract

The invention discloses a formwork device for constructing an inclined shaft working surface in a coal mine. The formwork device mainly comprises portals, fixing oil cylinders, walking mechanisms, framework withdrawing cylinders, a bottom framework, a left side framework, a right side framework, main lifting oil cylinders, main declining oil cylinders, framework fixing bases, a portal bottom longitudinal beam I and a portal bottom longitudinal beam II, wherein square holes are formed in the two ends of the portal bottom longitudinal beam I and the portal bottom longitudinal beam II respectively; the portal bottom longitudinal beam I and the portal bottom longitudinal beam II are arranged side by side; the four walking mechanisms are arranged on the lower parts of the two ends of the portal bottom longitudinal beam I and the portal bottom longitudinal beam II; lifting oil cylinder columns on the walking mechanisms are inserted into the square holes in the two ends of the portal bottom longitudinal beam I and the portal bottom longitudinal beam II respectively; the lifting oil cylinder columns on the walking mechanisms are connected with corresponding ends of the main lifting oil cylinders; the other ends of the main lifting oil cylinders are connected to the bottoms of triangular ribs on one sides of the portals. The formwork device is high in mechanization, low in labor intensity and less in manpower investment, can effectively reduce the cost, and achieves parallel digging, waste rock-removing and pouring operations.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a formwork mechanical device used for pouring in the working face of an inclined shaft. Background technique [0002] As more and more shafts are developed in inclined shafts in coal mines, the use of traditional technology to pour templates into inclined shafts requires high labor intensity, frequent movement of vertical arches, poor appearance and aesthetics of shaft walls, and slow footage, which cannot achieve real construction. Parallel operation seriously affects the construction speed. Contents of the invention [0003] In order to make up for the shortcomings of the existing technology and solve the problems of high manual labor intensity, frequent movement of the vertical arch, poor appearance and aesthetics of the shaft wall, and slow footage level, a construction formwork device for the inclined shaft working face of the coal mine was designed. [0004] The technical solution ...
