Description
Technical field
The utility model relates to the support apparatus of the boring head that coal mining uses, and is specially a kind of boring head temporary support device.
Background technology
Remarkable increase along with China's coal-mine mining rate and scale, and the development of modernization fully-mechanized mining technology, the particularly large scale application of large mining height full-seam mining technology, under new Circumstances of Market Economy, driving technology has become a bottleneck of coal production development.Particularly boring head temporary lining system is the technical barrier in puzzlement coal production field all the time.Resolve this problem, not only can reach the purpose that improves work efficiency, can also ensure the balance of coal mine excavation relation, be conducive to stable, the high yield, safety of coal production, efficiently.The existing driving face temporary lining general using of meeting head on is fixed on steel pipe on back as forestope, and fixedly supporting mesh is realized the driving face temporary lining of meeting head between forestope.Existing driving face is met head on, and temporary lining system works intensity is large, the operating time long, the control top area is little, safe effect is poor.Although the automation equipment that exists some to realize boring head temporary lining function, supporting effect is poor, structure is too complicated, cost is high, and single boring head temporary support device can not be realized mechanical drivage with the hydraulic support cooperating.。
Summary of the invention
The problem of the utility model in order to solve existing boring head temporary support device weak effect, complex structure and can not to be used in conjunction with hydraulic support provides a kind of boring head temporary support device.
the utility model is to adopt following technical scheme to realize: the boring head temporary support device, comprise extensible canopy, temporary support, one-level forces side board and secondary to force side board, extensible canopy is made of beam column and beam head, the beam column top is provided with temporary support, temporary support comprises top frame, top frame is made of channel-section steel and the curved steel tube that is fixed on channel-section steel, the top frame below is provided with two row's triangle steelframes, two row's triangle steelframes are stuck in beam column both sides, utilize bolt to fix between temporary support front end and beam head, the beam column below is provided with the jack engaging lug, the special-purpose connecting pin of the beam head front end utilization of extensible canopy is hinged with one-level and forces side board, one-level is forced the special-purpose connecting pin of side board front end utilization to be hinged with secondary and is forced side board, one-level is provided with former and later two jack engaging lugs below forcing side board, secondary is provided with the jack engaging lug below forcing side board, between the jack engaging lug of the rear side that the jack engaging lug on the beam column of extensible canopy and one-level are forced side board, one-level is forced between the jack engaging lug of front side of side board and jack engaging lug that secondary is forced side board 4 and is connected with flexible jack.(the orientation such as " top " that relates in foregoing description, " below ", " front side ", " rear side " are one-level when forcing side board and secondary to force side board to be complete deployed condition location expression.）
The channel-section steel of temporary support and the structure of curved steel tube on being fixed on channel-section steel guarantee that the temporary support surface adopts cambered surface contact with the top board surface, the frictional force between minimizing temporary support surface and top board, upward top set net and steel band when being convenient to temporary lining.
During use, extensible canopy is affixed on hydraulic support or other fastenings, the fluid,matching pressure control system uses, thereby forces side board and secondary force the expansion of side board or fold by the flexible one-level of controlling of controlling two flexible jack, and realizes mechanization temporary lining.
The beneficial effects of the utility model are as follows: utilize hydraulically powered two-stage grillage supporting structure, realized the automated job of temporary lining.The utility model protects the top, the wall supporting area is large, protects the top, the wall supporting setting load is larger, and strong adaptability can be used in conjunction with braced structures arbitrarily highly effective and safe applicable to all driving faces.
