Description
Technical field
The utility model is related to the monomer branch of a kind of Safety of Coal Mine Production protective device more particularly to a kind of underground mine use
Column support device.
Background technology
As equipment enlarging, Mechanization Level are promoted, the also corresponding increase of eye or stope drift active workings cross dimensions and height is cut,
And then supporting intensity also needs to enhance.Individual prop is generally used for cutting eye and sets support canopy or back production as a kind of passive protecting form
Lame advanced supporting section.Due to without contact, being easy to topple in no support force or while having impact force between individual prop.In order to anti-
Only to topple over, current method is that anti-down rope is hung between individual prop, although there is certain anti-down ability, its protecting against shock energy
Power is relatively inadequate, and reliability is not very high, and the secondary recovery utilization rate of anti-down rope is not relatively high, wastes object significantly
Material, increases the input of cost.
Invention content
To overcome above-mentioned technical problem, the utility model to provide a kind of individual prop easy to use, anti-down ability is strong
Support device.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of individual prop support device, including connecting rod, the after-frame that is respectively set at the connecting rod both ends fix dress
It sets and preceding rack supporting device, the after-frame fixing device is two symmetrical semi-circular shape hoop pieces of one end hinge-connection, each described
The other end of hoop pieces is equipped with lug, and the preceding rack supporting device is the supporting rack to take the shape of the letter U, two lugs and support frame as described above
Both ends connected by dismountable fastener, the connecting rod includes the body of rod and the middleware for being connected to the body of rod both ends,
It is equipped with protrusion in the both ends of the surface of the body of rod, one end of two middlewares is equipped with the groove to match with the protrusion, separately
One end is respectively fixedly connected with the extrados of one of them hoop pieces and the bottom of support frame as described above, the protrusion and the groove
Hinge-connection.
It is equipped with anti-skidding liner in the hoop pieces intrados.
The fastener includes bolt and is connected on the bolt and with female sleeve, the interior spiral shell of the sleeve
The screw thread of line and the bolt matches, and rotating bar is radially provided in one end of the sleeve.
The utility model has the positive effect that：
The utility model and monomer column are used cooperatively, the safety during individual prop is set and stabilization can be improved
Property, avoid individual prop that the pressure release of falling column casualty accident occurs；By the way that anti-skidding liner is arranged in hoop pieces intrados, can prevent from being fixed on
It skids when on monomer column；By the application of the fastener, monomer column can be conveniently loaded and unloaded, improves working efficiency.

Sleeve, 10, rotating bar.
Specific implementation mode
Referring to attached drawing, a kind of individual prop support device, including connecting rod, after the connecting rod both ends are respectively set
Frame fixing device and preceding rack supporting device, the after-frame fixing device are two symmetrical semi-circular shape hoop pieces 1 of one end hinge-connection,
The other end of each hoop pieces is equipped with lug 2, and the preceding rack supporting device is the supporting rack 3 to take the shape of the letter U, two lugs 2
And the both ends of support frame as described above 3 are connected by dismountable fastener 4, it, can by the way that hoop pieces 1, supporting rack 3 and fastener 4 is arranged
Conveniently securing unit pillar；The connecting rod includes the body of rod 5 and the middleware 6 for being connected to 5 both ends of the body of rod, in institute
The both ends of the surface for stating the body of rod 5 are equipped with protrusion, and one end of two middlewares 6 is equipped with the groove to match with the protrusion, another
End is respectively fixedly connected with the bottom of the extrados and support frame as described above 3 of one of them hoop pieces 1, the protrusion and the groove
Hinge-connection is connected the after-frame fixing device at both ends and preceding rack supporting device by connecting rod and middleware, due to described
The body of rod and the middleware are hinged, which ensure that certain amount of spin, can certain limit the adjustment present apparatus physical length
To adapt to the distance between two individual props.
It is equipped with anti-skidding liner in the hoop pieces intrados, first, can skid to avoid in securing unit pillar, second is that can
To protect individual prop surface not scratched by hoop pieces.
The fastener includes bolt and is connected on the bolt and with female sleeve, the interior spiral shell of the sleeve
The screw thread of line and the bolt matches, and rotating bar is radially provided in one end of the sleeve, can be square by this fastener constructions
Just handling individual prop, working efficiency higher.
The operation principle of the utility model is as follows：
The utility model is installed first, hoop pieces 1 and supporting rack 1 are fixed on individual prop, then passes through rotation
The both ends of lug 2 and supporting rack 3 are fixed up by the rotating bar 10 of fastener 4 respectively, to which fixed after-frame fixing device is with before
Rack supporting device.
