Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, if there are first and second described only for the purpose of distinguishing technical features, it is not understood that relative importance is indicated or implied or that the number of indicated technical features or the precedence of the indicated technical features is implicitly indicated or implied.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
As shown in fig. 1 and 2, the coal mine anchor supporting device comprises a base 3, a top beam 1 is arranged on the base 3, the base 3 and the top beam 1 are connected through a plurality of telescopic upright posts 2 and a link mechanism 4, a reserved opening is formed in the rear portion of the top beam 1, a supporting mechanism 6 is arranged in the rear portion of the base 3, and the supporting mechanism is located below the reserved opening 5.
During the gob-side entry retaining operation, the coal mining machine cuts coal, moves the support and pushes the front scraper conveyor, the support mechanism 6 is operated after the support is moved, and a top plate after the support moves forwards is supported in time. When the supporting mechanism 6 supports the top plate of the roadway, the driving end of the supporting mechanism extends out of the reserved opening 5 and props against the lower side of the top plate of the roadway, and therefore effective supporting is achieved.
Because the top plate which is not supported after the support is moved forwards is supported by the top beam in time, the top plate is supported, so that the top plate has no empty roof phenomenon, and the roof fall phenomenon can not occur, thereby ensuring the safety of personnel and equipment and improving the supporting efficiency of the top plate.
In the coal mine anchor supporting device, as shown in fig. 1, a top beam 1 comprises a front top beam and a rear top beam, wherein the rear part of the front top beam is hinged with the front part of the rear top beam; the front top beam and the rear top beam are both supported by at least one telescopic upright post 2; the link mechanism 4 is arranged between the hinged part of the front top beam and the rear top beam and the base 3.
