Abstract
The utility model relates to a colliery is combined and is adopted equipment for working face, especially relate to a colliery is combined and is adopted lever means of choosing flat of working face scraper conveyor, include the hydraulic support that is equipped with in underground coal mining completion collecting space area, the roof of hydraulic support compresses tightly on the upper wall in collecting space area, be connected with scraper conveyor in one side of hydraulic support, the articulated back timber one end that is used for choosing flat scraper conveyor sets up in one side bottom at scraper conveyor, the other end of articulated back timber is equipped with monomer hydraulic prop, one end of monomer hydraulic prop links firmly with articulated back timber, the other end of monomer hydraulic prop is supported on the roof of hydraulic support through the supporting seat is stable; the bottom of the hinged top beam is provided with a supporting block, the hinged top beam and the supporting block form a lever device, and the pressure of the single hydraulic prop is adopted to level the downward-pricked scraper conveyor. The utility model discloses the effectual scraper conveyor that has solved of simple structure can appear pricking the phenomenon down, leads to the problem of pass scraper conveyor difficulty.
Description
Technical Field
The utility model relates to a combine and adopt equipment for the working face, especially relate to a flat lever means of choosing of scraper conveyor.
Background
The fully mechanized mining face is a comprehensive mechanized mining face, and mainly refers to a mining face with a hydraulic support, a high-power scraper conveyor and a double-drum shearer, when a coal seam of the fully mechanized mining face goes downhill, the coal seam presses the hydraulic support, so that the scraper conveyor connected with the hydraulic support is subjected to a downward-pricking phenomenon, the scraper conveyor inclines, effective thrust cannot be provided for the hydraulic support, and the problem can be solved by angularly displacing the pushing scraper conveyor.
Disclosure of Invention
The utility model aims to avoid the not enough of prior art to provide a simple structure, convenient to use's solution the work face scraper conveyor prick down and push away motionless phenomenon, guarantee the lever means of leveling of gathering of work face scraper conveyor of combining of production task.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a leveling lever device of a scraper conveyor for a fully mechanized mining face comprises a hydraulic support arranged in a goaf after underground coal mining is completed, wherein a top plate of the hydraulic support is tightly pressed on the upper wall of the goaf; the bottom of the hinged top beam is provided with a supporting block, the hinged top beam and the supporting block form a lever device, and the pressure of a single hydraulic prop is adopted to level the downward-pricked scraper conveyor.
Furthermore, the supporting block is a square supporting block, and one corner of the square supporting block is used as a fulcrum.
The utility model has the advantages that: the utility model discloses regard as the fulcrum with the square timber, articulated back timber is as the pinch bar, raises the monomer and pushes down to choose flat scraper conveyor simple effectual solved the scraper conveyor chance and appear pricking down the phenomenon, leads to the problem of pass scraper conveyor difficulty.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the working state structure of the present invention.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Example 1: as shown in fig. 1, a leveling lever device of a fully mechanized mining face scraper conveyor comprises a hydraulic support 2 arranged in a goaf 1 after underground coal mining is completed, a top plate 3 of the hydraulic support 2 is tightly pressed on the upper wall of the goaf 1, a scraper conveyor 4 is connected to one side of the hydraulic support 2, one end of a hinged top beam 5 for leveling the scraper conveyor 4 is arranged at the bottom of one side of the scraper conveyor 4, a single hydraulic prop 7 is arranged at the other end of the hinged top beam 5, one end of the single hydraulic prop 7 is fixedly connected with the hinged top beam 5, and the other end of the single hydraulic prop 7 is stably supported on the top plate 3 of the hydraulic support 2 through a support seat 8; the bottom of the hinged top beam 5 is provided with a supporting block 6, the hinged top beam 5 and the supporting block 6 form a lever device, and the pressure of a single hydraulic prop 7 is used for flattening the downward-pricked scraper conveyor 4. The supporting block 6 is a square supporting block, and one corner of the square supporting block is used as a fulcrum.
The place operating personnel who lifts by crane scraper conveyor in needs beat earlier and establish and protect group's point post, confirms that hydraulic support 2's roof 3 is stable after, gets into the coal wall and clears coal, empties 4 forward positions downside of scraper conveyor, and it installs to get into 4 below scraper conveyor along with the working face passes the utility model discloses the structure uses on hydraulic prop 7 withstands hydraulic support 2's roof 3, operates hydraulic prop 7, utilizes articulated back timber 5 and the scraper conveyor 4 of pricking down of lever arrangement that supporting shoe 6 formed to choose to level, treats that the working face pushes away and adopts two cycles after, takes the utility model discloses the structure.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
