Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Being provided by Fig. 1-3, this utility model includes stable support structure, retractable supports structure, hydraulic system and wall supporting system.
Stably prop up support system to determine supporting construction and include fixing pillar (2), rigid bar (1), fixing protect head piece (4) and base (3); Rigid bar (1) is provided with sliding tray (5); The scalable handling groove (6) protecting head piece (18) it is provided with in sliding tray (5) front end; Anti-stamp bottom structure (7) it is provided with in the rear end of base (2); It is provided with advancing jack (8) in the front end of base (2).
Retractable supports structure includes scalable back timber (9), mobile pillar (10), moves and protect head piece (11), advancing jack (8) and base (3); It is provided with lead-over groove (12) at scalable back timber (9) middle part; Mobile prop liner (3) front end is provided with anti-stamp bottom structure (7).
Hydraulic system includes the hydraulic prop in supporting construction and advancing jack (8), fixing pillar (2), mobile pillar (10) and advancing jack (8) are connected with hydraulic power unit by valve group, stable support structure and the mutual push-and-pull of retractable supports structure is made, it is achieved underground coal mine driving face automatic moving type temporary shoring bracket automatically moves forward with driving by hydraulic system.
Wall supporting system includes the wall supporting device (13) on rigid bar (2) and the wall supporting device (13) on base (3); Hang flexible protecting wire net (14) between upper and lower wall supporting device (13), be connected by spring (15) between flexible protecting wire net (14) and wall supporting device (13).
When this utility model uses, underground coal mine driving face automatic moving type temporary shoring bracket being installed in driving face, wall supporting device (13) pressurizes, flexible protecting wire net (14) tension, supporting two is helped, and fixing pillar (2) pressurization is risen, and fixes and protects head piece (4) supporting roof; Tunnel forward with driving face, advancing jack (8) pressurization elongation, promote mobile pillar (10) reach, scalable back timber (9) and the mobile head piece (11) that protects protract, support the new top board exposed, now the scalable head piece (18) that protects is in compressive state, is parked in the handling groove (6) that rigid bar (1) is front; When advancing jack (8) overhang reaches the half of rated value, lead-over groove (12) leaks gradually cruelly, and the flexible spring (15) protected in head piece (18) extends gradually, and supporter (17) stretches out; When lead-over groove (12) all leaks cruelly, the scalable head piece (18) that protects is assemblied on scalable back timber (9), moves forward with scalable back timber (9) extension, strengthens the supporting to top board. When advancing jack (8) reaches maximal dilation amount, mobile pillar (10) pressurization jack-up, fixing pillar (2) pressure release, wall supporting device (13) pressure release, advancing jack (8) shrinks tries to stop people from fighting each other, and stable support structure is pulled to development end;Trying to stop people from fighting each other in process, scalable protect after head piece (18) returns handling groove (6), continue to try to stop people from fighting each other, depart from lead-over groove (12), the scalable head piece (18) that protects separates with scalable back timber (9); After having tried to stop people from fighting each other, roof supporting is risen in stable support structure pressurization, and wall supporting device (13) pressurization supporting two is helped. Realize underground coal mine development end automatic moving type temporary shoring bracket and automatically move frame, supporting roof.
