Description

Technical Field

[0001] The utility model belongs to the technical field of mining engineering filling, and in particular relates to a portable blocking device for drilling holes in underground goaf areas. Background Art

[0002] During the filling process of underground goaf, according to the filling engineering design, it is necessary to check in advance the prospecting holes, blasting connection holes, drainage holes and other types of boreholes within the goaf, and then go to the site to find the openings outside the goaf to expose the position and block them, so as to avoid the occurrence of difficult-to-handle drilling leakage filling body incidents during filling. This is an important link in the safety and technical management of goaf filling. At present, when blocking these various types of boreholes that affect filling, because most of the openings are at the top of abandoned tunnels, the existing technology usually sets up an operating platform, and is limited by the construction site environment. The working environment is poor, and some areas are not convenient for drilling and making safety rope hooks. The operation is inconvenient, very time-consuming and laborious, and the aerial operation is unsafe, and the hand will be injured when the anchor and other materials are blocked manually. At present, there is no tool specifically used for blocking the boreholes in underground goaf. For this reason, it is very necessary to develop a portable blocking device for underground goaf drilling that can solve the above problems. Utility Model Content

[0004] The purpose of the utility model is achieved in this way, including an operating rod, a filling depth positioning ring, an installation sleeve, an anchor filling sleeve, a filling sleeve positioning ring and a movable chassis, one end of the operating rod is fixedly connected to the center of the movable chassis, and the other end is an external thread structure, a through hole is provided in the center of one end of the anchor filling sleeve, and the outside of the through hole is fixedly connected to one end of the installation sleeve, and the other end of the anchor filling sleeve is an open structure, the filling sleeve positioning ring is sleeved and fixed on the middle part outside the anchor filling sleeve, the operating rod passes through the installation sleeve, and the movable chassis is located in the anchor filling sleeve, the operating rod body is slidably matched with the installation sleeve, and the filling depth positioning ring is sleeved and fixed on the operating rod.

[0005] Preferably, the external thread structure at the end of the operating rod is connected to the internal thread end of the extension rod. The end of the extension rod may also be provided with an external thread structure. When the extension rod is not long enough, the extension rod is connected as needed; specifically, the length of the extension rod is 1m.

[0006] Preferably, when the movable chassis is located at the end of the anchor filling sleeve, the distance between the filling depth positioning ring and the installation sleeve is 1 m.

[0007] Preferably, the operating rod is detachably connected to the movable chassis.

[0008] The beneficial effects of the utility model are as follows: the utility model is specially used for the drilling and blocking construction in the underground goaf area. The operator only needs to hold the device to complete the construction, and there is no need to build an operating platform and suspend the operation in the air, which greatly improves the construction efficiency and safety, and the operator's hands will not contact the anchoring agent during the blocking process; the utility model can deliver the anchoring agent to the required depth to meet the construction requirements, and the entire operation process is very convenient. The filling sleeve positioning ring can assist in fixing the device, greatly enhancing the stability of the operation process; the utility model also has the advantages of simple structure and easy processing.

[0013] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention belong to the protection scope of the present invention.

[0014] Example 1

[0015] As attached Figure 1~Figure 2As shown, the portable blocking device for underground goaf drilling in this embodiment includes an operating rod 1, a filling depth positioning ring 2, an installation sleeve 3, an anchor filling sleeve 4, a filling sleeve positioning ring 5 and a movable chassis 6. One end of the operating rod 1 is fixedly connected to the center of the movable chassis 6, and the other end is an external thread structure. A through hole is provided in the center of one end of the anchor filling sleeve 4, and the outside of the through hole is fixedly connected to one end of the installation sleeve 3. The other end of the anchor filling sleeve 4 is an open structure. The filling sleeve positioning ring 5 is sleeved and fixed in the middle of the outside of the anchor filling sleeve 4. The operating rod 1 passes through the installation sleeve 4. Sleeve 3, and the movable chassis 6 is located in the anchor filling sleeve 4, the operating rod 1 is slidably matched with the installation sleeve 3, and the filling depth positioning ring 2 is sleeved and fixed on the operating rod 1; when the movable chassis 6 is located at the end of the anchor filling sleeve 4, the distance between the filling depth positioning ring 2 and the installation sleeve 3 is 1m; wherein, the operating rod 1 is 2m long and has an outer diameter of 20mm, the outer diameter of the filling depth positioning ring 2 is 50mm, the length of the installation sleeve 3 is 100mm, the length of the anchor filling sleeve 4 is 150mm, the inner diameter is 80mm, and the outer diameter of the filling sleeve positioning ring 5 is 100mm;
