Abstract
The utility model discloses a kind of gob side entries to force side column Special anchor rod pallet, it include: tray body, work steel connector, column slot, stiffening plate, bolthole is provided in the centre of tray body, tray body is fixed at side above work steel connector, column slot is fixed at the other side of work steel connector, is fixedly installed a triangular reinforcing plate respectively in tray body and work steel connector two sides.Have the characteristics that supporting effect is good, support cost is lower, be conducive to mining conveying ventilation.
Description
Technical field
The utility model belongs to underground coal mine coal road driuing along goaf roadside support security technology area, specifically a kind of along sky
Force side column Special anchor rod pallet in tunnel.
Background technique
It needs to excavate a large amount of tunnel in coal production engineering, in order to reduce tunnelling cost and improve coal resources
The rate of recovery needs to continue to optimize the support pattern in tunnel.In recent years, in order to reduce resources loss caused by protection coal pillar, coal road
Driuing along goaf technology is gradually applied in underground coal mine.Coal road gob side entry generally takes tool steel shed support pattern, later period lane
It is larger that road deforms maintenance capacity, also has carry out supporting using bolting with wire mesh+force side column technology at present, and later period road maintenance amount is small, it
It is, using forcing side column to help to carry out support reinforcement to two, to force side column sliding in order to prevent while carrying out bolting with wire mesh to top plate
Or topple over, it needing using anti-down bracing means to forcing side column to be fixed, on the one hand this mode increases roadway support cost,
On the other hand anti-down bracing means occupied space, is unfavorable for underground transportation and mine ventilation, affects mine safety to a certain degree
Production.
Utility model content
That the purpose of the utility model is to provide a kind of supporting effects is good, support cost is lower, is conducive to mining conveying ventilation
Gob side entry force side column Special anchor rod pallet.
To achieve the goals above, the utility model includes: tray body, work steel connector, column slot, stiffening plate, in pallet
The centre of body is provided with bolthole, and tray body is fixed at side above work steel connector, and column slot is fixed at the connection of work steel
The other side of body is fixedly installed a triangular reinforcing plate in tray body and work steel connector two sides respectively.
In this way when carrying out bolting with wire mesh to top plate, the utility model is fixed to along the high strength anchor bar of empty side top plate,
When using forcing side column to help to carry out support reinforcement to two, side column can will be forced securely to be stuck in column slot, and effectively prevent forcing side column sliding
Or topple over, not only play the role of anchor rod pallet board, but also can force side that supporting is fixed on column, to play the reinforcing of portion of gob side entry side
Avoid the effect of lane compressive strain.Have the characteristics that supporting effect is good, support cost is lower, be conducive to mining conveying ventilation, simultaneously
The labor intensity for alleviating worker can satisfy safety in production needs.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the overlooking structure diagram of the utility model.
Fig. 2 is the schematic view of the front view of the utility model.
Specific embodiment
As seen from Figure 1, Figure 2, the utility model includes: tray body 1, work steel connector 3, column slot 4, stiffening plate 6.Tray body
1 is processed into square platy structure using mining steel plate, and work steel connector 3 uses mining work steel processing and fabricating, and column slot 4 is using mining
Channel steel processing and fabricating had not only met underground coal mine use environment, but also has facilitated selection.It is provided with bolthole 2 in the centre of tray body 1, is used
Anchor bar body is penetrated in construction to be fixed.Tray body 1 be fixedly welded be arranged on work steel connector 3 side, tray body and
Work steel connector equivalent width, column slot 4 are fixedly welded the other side that work steel connector 3 is arranged in, the width of work steel connector and
Height is consistent with column slot, in production, to make the inner groovy of column slot 4 and force column 5 is helped to be mutually matched, so as to column slot when in use
4 can securely block force side column 5.It is fixedly welded respectively in tray body 1 and 3 two sides of work steel connector and is provided with a triangle
Stiffening plate 6 meets underground coal mine supporting requirement for enhancing firm and reliable connection between tray body and work steel connector.This reality
Series of products can be made according to the size of supporting section and pillar with novel specification size.
