Abstract
The invention relates to the technical field of coal mine mining equipment and particularly relates to a coal-mining protecting device with a telescopic turnover mechanism. The coal-mining protecting device comprises a top beam of a box body structure, wherein hydraulic support posts are connected to the lower part of the top beam; a box body is provided with a first oil cylinder which drives a telescopic beam to stretch out or shrink back and do a reciprocating motion, a push rod of the first oil cylinder is connected with the telescopic beam, and a stretching end of the telescopic beam is fixedly connected with a turnover beam through a second hinge; a second oil cylinder capable of overturning or resetting the turnover beam according to set positions is further arranged in the box body, and a push rod of the second oil cylinder is connected with the turnover beam through a first hinge. According to the coal-mining protecting device with the telescopic turnover mechanism, the turnover beam can protect a coal wall and prevent the coal wall from collapsing, so that the mining safety of a complex coal bed difficult to mine is guaranteed; the stretching and turnover actions of the telescopic beam and the turnover beam can be respectively independently controlled, so that the actions are accurate, stable and reliable.
Description
Technical field
The present invention relates to coal mining equipment technical field, being specifically related to is a kind of coal mining protective device with telescopic turning mechanism.
Background technology
The interim cover organizations of the combined suspension moving hydraulic support that current coal mining uses is more common in or only has extensible canopy to protect top, only has flip beam wall supporting, and the coal seam conditions in colliery varies and ever-changing, go deep into condition of coal seam occurrence good block section by fewer and feweri particularly along with coal mining, the serious situation of top board or the soft easy inbreak of crushing voerhead coal, coal wall caving is more and more general.For this reason, be necessary two kinds of cover organizations to combine realization not only to have protected and push up but also wall supporting.Realize not only stretching but also outside turn over function, also have a kind of structural concept, namely stretch, overturn and controlled by same oil cylinder.But the disadvantage of this scheme is flexible and upset two actions will be provided by same parts, and this interlock has sequencing, therefore, just requires limited location mechanism, however, all there is some problems in the reliability of action, stability and accuracy.
Summary of the invention
In order to overcome defect of the prior art; the invention provides a kind of coal mining protective device with telescopic turning mechanism to solve top board or soft easily the collapsing of crushing voerhead coal in process of coal mining and emit the wall supporting problem in brought timely shielding and easy wall caving coal seam; the exploitation of more complicated seam can be adapted to, ensure that the safety of complicated difficult seam mining.
The present invention is achieved through the following technical solutions: a kind of coal mining protective device with telescopic turning mechanism, comprise the back timber of body structure, described back timber bottom is connected with hydraulic prop, described casing is provided with and extensible canopy is stretched out or the first oil cylinder moved reciprocatingly of retracting, the push rod of described first oil cylinder is connected with described extensible canopy, the external part of described extensible canopy is fixedly connected with by the second hinge with flip beam, described extensible canopy is also provided with the second oil cylinder making described flip beam overturn according to desired location or reset, the push rod of described second oil cylinder is connected with described flip beam by the first hinge.
Further, described hydraulic prop is four, and is symmetrical arranged.
Further, described first oil cylinder is 2, is arranged on described casing two symmetrical positions of side.
Further, described first hinge is arranged on the center of described flip beam.
Further, described flip beam is provided with holder, described holder is packed in the external part of described extensible canopy, the push rod of described first oil cylinder is connected with described holder, described flip beam is connected with described holder by described second hinge, and the push rod of described second oil cylinder is connected with described flip beam by described first hinge.
Further, described first hinge is arranged on the center of described flip beam.
Further, described flip beam is provided with the stretching device of adjustment length.
Compared with prior art, superior effect is: the top board that the present invention exposes after extensible canopy can be made to protect exploitation in time or top coal, flip beam is responsible for protecting rib, prevents rib to be caving wall caving, ensure that the safety of complicated difficult seam mining.This device independently can control stretching out and rotary movement of extensible canopy and flip beam, makes two cover actions independent separately, action accurately, stable and more reliable.
