Description
Technical field
The present invention relates to the supporting in downhole coal mine fully-mechanized mining working Kong Liu lane, especially relate to the protective cradle for roadside packing body of wall.
Background technology
Downhole coal mine fully-mechanized mining working edge air gallery technology, mine laneway driving amount can be reduced, alleviate excavation replacement anxiety, shorten the face moving time, prevent from getting angry and extending mine service-life, and provide convenient for solving the gas control of highly gassy mine, improve the safety of pit mining.At present, the filled wall that gob side entry retaining adopts High-water quick consolidated filling materials to arrange, achieves mechanized filling.But existing deficiency is, body of wall from the solidifying of packing material, be enhanced to the process of roof supporting design nominal strength, along with the propelling of work plane, the carrying roof pressure making filled wall too early, causes body of wall to damage.
Summary of the invention
The object of the invention is to provide a kind of protective cradle for roadside packing body of wall; reach and solidify in the time period of design intensity at filled wall; for isolating the spoil of erecting dense individual props; for wall outer side top board provides support, make body of wall in process of setting, not carry roof pressure and solidify to protect body of wall.
For achieving the above object, the present invention takes following technical proposals:
Protective cradle for roadside packing body of wall of the present invention, comprises front support stand and rear support stand, and described front support stand and rear support stand head and the tail are hinged; Described front support stand comprises front back timber and front base, be arranged on the hydraulically extensible column between front back timber and front base, the rear portion of front back timber and front base is hinged by swing-bar mechanism, the front end of front back timber is hinged with extensible canopy, described extensible canopy is hinged with the telescopic oil cylinder be arranged on front back timber, be provided with in the front end of front base and move connector for drawing of being connected with fully-mechanized mining working support, described rear support stand comprises rear back timber and rear base, be arranged on the hydraulically extensible column between rear back timber and rear base, the rear portion of rear support stand is shield beam structure; The goaf side of described forward and backward back timber is all to being arranged with upper waste rock board, the forward and backward base being positioned at described upper waste rock board side is all upwards provided with the lower waster rock blocking plate overlapped with upper waste rock board, the base of lower end respectively with corresponding of described lower waster rock blocking plate is hinged, and the upper end of lower waster rock blocking plate is hinged with corresponding base respectively by connecting rod.
Described forward and backward back timber is provided with conventional movable side protection plate mechanism relative to the opposite side being provided with described upper waste rock board.
The caving shield at described rear support stand rear portion is positioned at goaf side and arranges fixing large side plate, and opposite side arranges movable side protection plate.
The invention has the advantages that primary structure form adopts similar to the hydraulic support that colliery uses, adapted to down-hole and installed and used condition.Be arranged on the upper and lower waste rock board on described forward and backward back timber and base and side guard board; with the large side plate be arranged on the caving shield of described rear support stand rear portion and side guard board; common formation is across the isolation barrier of the rubble that falls; and meet when this protective cradle is in minimum altitude and do not interfere, still keep mutual headlap when being in maximum height, reach the seamless supporting to roadside packing body of wall and top board.This protective cradle passes through hinge by front support stand and rear support stand first place, and like this, the condition of transport of going into the well after meeting fractionation on the one hand, can adapt to again the fluctuations of the other top board in lane, base plate on the other hand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, the protective cradle for roadside packing body of wall of the present invention, comprises front support stand and rear support stand, and described front support stand and rear support stand head and the tail are hinged by bearing pin 1,2; Described front support stand comprises front back timber 3 and front base 4, be arranged on the hydraulically extensible column 5 between front back timber 3 and front base 4, the rear portion of front back timber 3 and front base 4 is hinged by swing-bar mechanism 6, the front end of front back timber 3 is hinged with extensible canopy 7, described extensible canopy 7 is hinged with the telescopic oil cylinder 8 be arranged on front back timber 3, is provided with moves connector 9 for drawing of being connected with fully-mechanized mining working support in the front end of front base 4; Described rear support stand comprises rear back timber 10 and rear base 11, be arranged on the hydraulically extensible column 12,13 between rear back timber 10 and rear base 11, the rear portion of rear support stand is caving shield 14 structure, and described caving shield 14 goaf side arranges fixing large side plate, and opposite side arranges movable side protection plate; The goaf side of described forward and backward back timber 3,10 is all to being arranged with upper waste rock board 15,16, the forward and backward base 4,11 being positioned at described upper waste rock board 15,16 side is all upwards provided with the lower waster rock blocking plate 17,18 overlapped with upper waste rock board 15,16, the lower end of described lower waster rock blocking plate 17,18 respectively with corresponding forward and backward base 4,11 hinged, the upper end of lower waster rock blocking plate 17,18 is respectively by connecting rod 19,20 and corresponding forward and backward base 4,11 hinged; Forward and backward back timber 3,10 is provided with conventional movable side protection plate mechanism relative to the opposite side being provided with upper waste rock board 15,16.
The present invention is after down-hole combined mining working installs, and adjustment front support stand makes it fully contact roof with the back timber 3,10 of rear support stand, namely define with this protective cradle be boundary, space, both sides in this protective cradle length range.By upper and lower waste rock board and the large side plate of caving shield goaf across the rubble fallen with stay lane space to keep apart.In Liu Xiang side, coordinate with other equipment, the engineerings such as gob side entry retaining body of wall filling can be implemented.Move connector 9 be connected with anterior fully-mechanized mining working support by drawing of front support stand base 4 front end, adjust described hydraulically extensible column and make forward and backward back timber 3,10 depart from top board, advance with fully-mechanized mining working, again after roof supporting, namely form next working cycles.
The present invention solidifies filled wall 10-20 coal mining step pitch staying lane to move towards direction is protected; filled wall is avoided to carry roof pressure too early; reach and ensure that filled wall has the sufficient time to be cured to the nominal strength of design, simultaneously also for staff provides the space of operation outside a filled wall.
