Description

Technical Field

[0001] The invention relates to the technical field of shaft construction, in particular to a hole sealing device based on a hole sealing plug. Background Art

[0002] At present, in the construction of various vertical shafts involved in coal mines, non-coal mines, tunnel ventilation and other underground projects, the most commonly used method is the ordinary drilling and blasting method, especially for vertical shafts with complex engineering geological conditions and hydrogeological conditions. The drilling process and the charging process of the vertical shaft drilling and blasting method are connecting processes. The charging process can only be carried out after all the holes in the drilling process are completed and qualified. Since the drilling process requires drilling multiple holes, during the drilling construction process, due to human and equipment disturbances, rock cuttings and sediment fall into the completed boreholes under the action of gravity, causing blockage. To prevent this from happening, the holes need to be sealed in time after drilling. At present, manual hammering and wedge-in wooden plugs are used to seal the holes, which has high labor intensity and poor working environment. It is time-consuming and laborious to remove the wooden plugs during the charging process. It is urgent to develop a drilling and sealing device for the vertical shaft drilling and blasting method to replace manual sealing. Summary of the invention

By providing the guide rod and the guide hole, the stability of the hole sealing plug movement can be improved, so that the hole sealing plug can smoothly enter the hole opening.

[0008] The above-mentioned sealing device based on the sealing plug comprises a hollow cylinder, one end of which has an outer diameter larger than the drilled hole, and the other end of which has an outer diameter smaller than the drilled hole; a convex edge extending radially outward is provided on the large-diameter end of the hollow cylinder, and a bottom plate is connected to the small-diameter end of the hollow cylinder, and a guide hole is opened on the bottom plate.

[0009] In the above-mentioned sealing device based on sealing plugs, more than two sealing plugs are arranged in the collecting tube, and the small diameter end of the first sealing plug is inserted into the second sealing plug from the large diameter end of the second sealing plug.

By arranging the rubber ring, it is possible to prevent the hole sealing plug in the collecting tube from falling off.

[0011] In the above-mentioned sealing device based on the sealing plug, the toggle component includes a toggle plate, one end of which is connected to the output shaft of the corner cylinder, and the toggle plate is arranged along the radial direction of the corner cylinder. More than two toggle plates are arranged on the output shaft of the corner cylinder at equal intervals along the circumferential direction.

[0012] In the above-mentioned sealing device based on the sealing plug, a rubber sheet is connected to the free end of the shifting plate, and the rubber sheet is attached to the surface of the sealing plug.

[0013] In the above-mentioned sealing device based on the sealing plug, angle cylinders are arranged on both sides of the collecting cylinder, and shifting components are arranged on the output shafts of the two angle cylinders; the minimum distance between the free ends of the shifting plates of the two shifting components is less than or equal to the maximum outer diameter of the sealing plug.
