Abstract
A steep coal seam work face double-lane forepoling hydraulic support side protection device comprises a hydraulic support and a top beam, wherein the top beam is arranged on the hydraulic support, top protection beams arranged on two sides of the top beam are hinged with side protection boards, the middle of each side protection board is hinged with a side protection jack, the other end of each side protection jack is fixed on each top protection beam, each top protection beam is hinged with a top protection jack, the other end of the top protection jack is fixed on the top beam, and the side protection boards are triangular. According to the steep coal seam work face double-lane forepoling hydraulic support side protection device, the side protection boards and the top protection beams replace original side protection boards, a side protection effect and a top protection effect are good, and safety and reliability are achieved. In addition, angles can be regulated through the top protection jacks and the side protection jacks, supporting and protecting requirements of steep coal seams are met, full-hydraulic automatic control is achieved, labor intensity is reduced, and good supporting and protecting effects are achieved.
Description
Technical field
The utility model relates to the coal mine machinery technical field, is specifically related to a kind of half-edge coal seam work plane two lane forepoling hydraulic support side protection units.
Background technology
Comprehensive mechanical coal mining is the important symbol of coal mining technological progress, is the important means that increases output, increase economic benefit, improves safety.The most important condition of Coal Production is safety, and the fully-mechanized mining working surface hydraulic support advance support is one of main means that improve safety in the coal mining.
Half-edge coal seam work plane two lane forepoling hydraulic supports are difficult points in the hydraulic support design, wherein protect pedestrains safety, prevent the slip of half-edge coal seam and rock stratum, prevent coal wall caving, are the most important things of Safety of Coal Mine Production.Half-edge coal seam work plane two lane forepoling hydraulic support side protection units prevent the shearing slip of coal seam and rock stratum exactly for work plane two lanes provide a pedestrains safety, prevent the method for coal wall caving, guarantee normally carrying out of coal work.Because half-edge coal seam work plane inclination angle is greater than 45
oThe coal seam is subjected to shear strain serious in process of production, be very easy between coal seam and rock stratum form to shear slide, coal seam and rock stratum integral body glide along aspect, cause coal wall caving, cause wall caving to be hurted sb.'s feelings, stop passing road, the safety in production in serious threat colliery, the purpose of this hydraulic support side protection unit are exactly the generation of avoiding this type of accident as possible.Present employed half-edge coal seam ahead work face hydraulic support can not carry out side to be protected.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of strong half-edge coal seam work plane two lane forepoling hydraulic support side protection units simple and compact for structure, safe, stable are provided.
For achieving the above object, half-edge coal seam work plane two lane forepoling hydraulic support side protection units of the present invention, comprise hydraulic support, be located at the back timber on the hydraulic support, be provided with in described back timber both sides and protect back timber, protect and be hinged with side guard board on the back timber, the middle part of side guard board is hinged with the other end and is fixed on the side of protecting on the back timber and protects jack, and described protecting is hinged with the other end and is fixed on and protects the top jack on the back timber on the back timber; Described side guard board is triangular in shape.
Beneficial effect: owing to adopted technique scheme, the utility model half-edge coal seam work plane two lane forepoling hydraulic support side protection units have good pedestrian protecting, prevent coal seam and rock stratum shearing slip, prevent the effect of coal wall caving, for the safety of coal mines supporting provides good help; This hydraulic support side protection unit adopts all-hydraulic automatic control, reduces labour intensity.It is simple in structure, and installation process is convenient, saves the labour, and whole process operation is simple, and is effective, safe and reliable, practical.
