The utility model provides a two-way anticreep clamp device of gas drainage can effectively take out and adopt pipeline interface chucking through forward clamp and reverse clamp, prevents to take out and adopt drill hole department gas drainage pipeline because external force or coal seam gas pressure will take out and adopt the pipeline and collapse out, avoids the gas transfinite.
Description
Technical Field
The utility model relates to a mine safety and gas drainage technical field specifically are a two-way anticreep clamp device of gas drainage.
Background
After the hole sealing and grouting of the gas extraction drill hole, connecting a PVC pipe for sealing the hole at the extraction drill hole with an extraction pipeline. The traditional connection mode directly adopts iron wire connection and hose clamp connection, and in a dark and humid environment underground, the iron wire is easy to corrode or slide, so that the iron wire connection fails, and gas is over-limited, so that the connection mode is eliminated; the hose clamp connection is more reliable than the iron wire connection, but the hose clamp is very easy to loosen under external force such as site worker construction dragging and the like and long-time underground corrosion, and the connector is very easy to collapse when the gas pressure of a coal seam is higher, so that the gas is over-limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two-way anticreep clamp device of gas drainage will take out through forward clamp and reverse clamp and take out the pipeline interface chucking to prevent to take out and adopt drill hole department gas drainage pipeline because external force or coal seam gas pressure will take out and take out the pipeline and collapse out, avoid the gas transfinite.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a two-way anticreep clamp device of gas drainage, includes forward clamp, reverse clamp, connecting rod one and connecting rod two, and forward clamp and reverse clamp are fixed respectively at the front end of a plurality of connecting rod one and a plurality of connecting rod two, and the end of connecting rod one and connecting rod two is relative, and the end of connecting rod one and connecting rod two has relative screw two, and the spiro union has the bolt on two relative screws, and forward clamp and reverse clamp body inboard have anti-skidding structure.
Preferably, the anti-slip structure is a barb.
As preferred technical scheme, the inboard barb of forward clamp body is the forward barb, the inboard barb of reverse clamp body is reverse barb, and the incline direction of forward barb and reverse barb is relative.
As a preferable technical scheme, the first connecting rod and the second connecting rod are both two, the two connecting rods are symmetrically distributed, and the two connecting rods are symmetrically distributed.
Preferably, the first connecting rod and the second connecting rod have the same length.
Preferably, the length of the first connecting rod and the length of the second connecting rod are 100-150 mm.
As the preferred technical scheme, the two opposite ends of the forward clamp body and the reverse clamp body are respectively provided with a first screw hole, and the clamp body is tightened through a bolt on the first screw hole.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a two-way anticreep clamp device of gas drainage can effectively take out and adopt pipeline interface chucking through forward clamp and reverse clamp, prevents to take out and adopt drill hole department gas drainage pipeline because external force or coal seam gas pressure will take out and adopt the pipeline and collapse out, avoids the gas transfinite.
Drawings
Fig. 1 is a schematic structural view of a gas extraction bidirectional anti-drop clamp device in an embodiment of the present invention;
in FIG. 1, 1-forward yoke; 2, a first screw hole; 3-positive barb; 4-a bolt; 5-screw hole II; 6-reverse hoop; 7-reverse barbs; 8, connecting rod one; 9-link two.
The specific implementation mode is as follows:
the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
As shown in figure 1, the bidirectional anti-falling clamp device for gas extraction comprises a forward clamp 1, a reverse clamp 6, a first connecting rod 8 and a second connecting rod 9, wherein the forward clamp 1 is fixed at the front ends of the first connecting rods 8, the reverse clamp 6 is fixed at the front ends of the second connecting rods 9, the tail ends of the first connecting rod 8 and the second connecting rod 9 are opposite, the tail ends of the first connecting rod 8 and the second connecting rod 9 are provided with opposite screw holes two 5, and bolts 4 are screwed on the opposite screw holes two 5. The two first connecting rods 8 are symmetrically distributed, and the two second connecting rods 9 are also symmetrically distributed.
The two opposite ends of the body of the forward clamp 1 and the reverse clamp 6 are respectively provided with a screw hole I2, and the clamp body is tensioned through bolts on the screw holes I2.
When the connecting device is used, the forward hoop 1 is hooped on a PVC pipe of a gas extraction drill hole, the reverse hoop 6 is hooped on an extraction hose of the gas extraction drill hole, the positions of the PVC pipe and the extraction hose are adjusted, the first connecting rod 8 is opposite to the second connecting rod 9, the bolt 4 is screwed on the second screw opening 5, the first connecting rod 8 is locked with the second connecting rod 9, and connection is completed.
The advantage of using the bolt 4 for connection is that the distance between the first connecting rod 8 and the second connecting rod 9 can be conveniently adjusted, so that the extraction pipeline can be conveniently connected. In addition, if the first connecting rod 8 and the second connecting rod 9 are loosened, the bolt 4 can be screwed for fastening in the later period, so that the connection reliability of the extraction pipeline is ensured. The length of the first connecting rod 8 and the length of the second connecting rod 9 can be the same, for example, the lengths are both 100-150 mm, and therefore the forward and the reverse directions are all universal.
It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, other improvements obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
