Abstract
The utility model discloses a novel support type legless canopy. The novel support type legless canopy comprises top beams, wherein support seats for bearing the top beams are arranged near the two ends of a coal wall, below the top beams; each support seat comprises a transverse plate and an upright plate, a rib plate is arranged in the middle of the upright plate, and the two right-angle sides of the rib plate are respectively connected and fixed to the transverse plate and the upright plate; four anchor rod holes are formed in the upright plate and are distributed symmetrically with respect to the rib plate; each anchor hole is internally provided with an anchor rod anchored into a coal bed. Compared with the prior art, the legless canopy has the advantages of solving the problems that cracking and instability easily occur due to dirt band thinning, rigidity decreasing and bearing capacity reducing during coal mining under the dirt band of a layering work surface in layer mining, and simultaneously solving the problem that legs can not be erected when a bottom plate is severely wetted with water or is very soft.
Description
Technical field
The utility model relates to a kind of acnemia canopy, especially a kind of by the New Supporting formula acnemia canopy that adopts supporting seat to carry out supporting.
Background technology
Under separate zone production lower leaf face dirt band, mine, the attenuation of dirt band thickness, rigidity diminishes, supporting capacity diminishes, easily produce the crack unstability, grown by the mining induced fissure that affects that higher slice is adopted, in the roadway construction process, top board has lost original stability, very large potential safety hazard occurred.Dirt band is too thin, has exceeded the accommodation of anchor rete cord, and in addition, under the impact of goaf water, the anchor pole resin explosive roll is ineffective, may make whole bolt support system ineffective.Simultaneously softening at the effect lower shoe of trickle, H shaped steel shack and monomer canopy canopy leg brill end amount are very large, and supporting effect obviously reduces, and roof timbering needs new support pattern in this case.
Summary of the invention
The purpose of this utility model will provide a kind of New Supporting formula acnemia canopy exactly, adopts this support form, can be in the situation that drench with rain and existing leg formula supporting was lost efficacy, top board is realized effectively supporting effectively.
For achieving the above object, the utility model by the following technical solutions:
A kind of New Supporting formula acnemia canopy, comprise back timber, and two ends, described back timber below at least respectively are provided with one, and for carrying the supporting seat of back timber, supporting seat is provided with bolthole, is provided with the anchor pole that anchors into coal seam in bolthole.
Further, described supporting seat is provided with four, lays respectively at four jiaos, top board.
Further, described supporting seat comprises transverse slat and the riser be fixedly connected with, and described bolthole is positioned on riser.
Further, described supporting seat also includes a gusset, and the two ends of gusset are connected with riser respectively at transverse slat.
Further, described bolthole is provided with four, and the gusset both sides respectively are provided with two, along gusset, are symmetrical arranged.
Further, described transverse slat is provided with the connecting rod fixing with back timber.
Further, described connecting hole is provided with two, and the gusset both sides respectively are provided with one, along gusset, are symmetrical arranged.
Further, the oblique lower setting of described bolthole.
Further, described riser, transverse slat and gusset are integrated.
The beneficial effects of the utility model show:
The utility model adopts supporting seat to be supported back timber, and the origin of force of supporting seat is not on the ground, but utilize anchor pole to be fixed on coal seam by bolthole, generation humidity in bottom surface still drenches with rain and can not exert an influence to supporting like this, thereby guarantees the effect of supporting.
Four jiaos of back timber all are provided with supporting seat, and so effectively supporting top beam, adapt to the irregular stressed of back timber, the phenomenon that while effectively avoiding the appearance deflection stressed, supporting was lost efficacy.
Supporting seat comprises transverse slat, riser and reinforcing rib, can be used for carrying back timber to transverse slat, and riser is used for fixing anchor bar, thereby forms whole support form; Reinforcing rib can effectively strengthen supporting effect, avoids occurring the reclinate phenomenon of transverse slat.
Bolthole and connecting hole are symmetrical arranged respectively about reinforcing rib, and effectively uniform stressed, further guarantee supporting effect.
The downward-sloping setting of bolthole, can effectively prevent from that back timber, supporting seat are stressed when larger anchor pole is extracted out from coal seam.

Fig. 2 is the supporting seat front view;
Fig. 3 is the supporting seat left view;
Fig. 4 is the supporting seat top view;
Fig. 5 is that supporting seat is used state diagram.
The specific embodiment
As Figure 1-4, a kind of New Supporting formula acnemia canopy, comprise back timber, and described back timber below respectively is provided with one for carrying the supporting seat of back timber near place, four jiaos, two ends of rib.
Described supporting seat comprises transverse slat 1 and riser 3, both rectangular shapes, be provided with gusset 2 at the middle part of riser 3, this gusset 2 is selected corresponding right angle trigonometry shape, two right-angle sides are connected and fixed respectively at transverse slat 1 and riser 3, on riser, 3 are provided with four boltholes 4, and bolthole 4 is symmetric about gusset 2, are provided with the anchor pole 6 that anchors into coal seam in bolthole 4.
Described transverse slat 1 is provided with the connecting hole fixing with back timber 5, and described connecting hole 5 is provided with two, and gusset 2 both sides respectively are provided with one, and is symmetrical arranged along gusset 2.
For increasing the ability to bear of integrated support seat, described riser 3, transverse slat 1 and gusset 2 are integrated, such as building moulding.
Setting up of acnemia side plates: be after drift section is dug into, forestope is held the back timber of the acnemia canopy that will set up, now under the acnemia canopy, set up interim canopy leg (individual prop) back timber fixed, now below back timber on rib " supporting base " position find the position of armature boring and mark good;
Acnemia canopy fixing anchor bar is installed: the bore position good at mark beaten armature boring with rig in rib, and each " supporting base " position is fixed with four anchor poles, adopts the method anchoring rod of full anchoring, and anchor pole is tray and anchor pole head not; Shown in Fig. 5.
Setting up of acnemia canopy " supporting base ": " supporting base " is arranged on the anchor pole fixed on rib, and the skyhook head;
Supporting base install and stable after, withdraw from interim canopy leg, the acnemia frame is set as merit.
