Description

Technical Field

[0001] This utility model relates to the field of gold mining technology, specifically to a device for plugging drill holes. Background Technology

[0002] In gold mining operations, it is usually necessary to first treat the foundation of the mining area. During the drilling process, water sources are often easily discovered, causing groundwater to flow into the excavated pit. Since the gold mining cycle is generally long and this groundwater cannot be pumped out, tools are needed to block the seepage holes in order to prevent the groundwater from affecting the mining progress.

[0003] A Chinese patent discloses a device for plugging drill holes, publication number CN203891828U, which includes a conical drill bit made of pine wood, a column, and a force-bearing block. The conical drill bit is located below the column, the force-bearing block is located above the column, and several turns of straw rope are wound around the middle of the column.

[0004] The above-mentioned device uses pine wood to manufacture the conical drill bit, column, and load-bearing block, which prevents the entire device from rotting in water. This is due to the inherent properties of pine wood. In addition, several turns of straw rope are glued and fixed in the middle of the column. When the smooth pine wood column is driven into the drill hole, the straw rope fixed in the middle of the column rubs against the hole wall of the overflow outlet, generating friction. This friction prevents the entire device from being pushed out of the drill hole by the pressure of the groundwater flow.

[0005] However, its structure is relatively simple, and the sealing process requires strong hammering. It is difficult to ensure that the force is applied to the accurate position, which may cause the pine wood plug to break during hammering. Moreover, when the water level drops, the pine wood plug will be exposed, and long-term weathering can easily cause the plug to crack, affecting the sealing effect. Utility Model Content

[0006] The purpose of this invention is to provide a device for plugging boreholes, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for plugging a drill hole includes a plugging cylinder, a plugging pressure plate fixedly connected to the top of the plugging cylinder, a connecting threaded seat fixedly installed at the center of the top of the plugging pressure plate, and a plugging screw disposed at the center of the upper and lower ends of the connecting threaded seat and the plugging pressure plate.

[0009] A connecting rod is fixedly installed at the bottom end of the sealing screw, and a sealing block is installed at the bottom end of the connecting rod through a connecting bolt. The sealing screw and the sealing pressure plate are rotatably connected, and the sealing screw and the connecting threaded seat are threadedly connected. A nut head is fixedly connected to the upper part of the outer ring of the sealing screw. Expansion grooves that are adapted to the sealing block are provided on both sides of the sealing cylinder at the lower part. The diameter of the sealing block is larger than the inner diameter of the sealing cylinder.

[0010] Preferably, the outer ring of the sealing cylinder is bonded with a rubber outer skin, and a sealing groove is provided at the upper position of the outer ring of the sealing cylinder, and a connecting thread seat is provided in the sealing groove.

[0011] Preferably, the upper part of the sealing block is tapered, and the sealing block is detachably connected to the connecting rod by connecting bolts.

[0012] Preferably, an installation hole is provided at the upper end of the front and rear ends of the sealing screw, and a handle is movably installed in the installation hole. The front and rear ends of the handle are threadedly connected to the installation block.

[0013] Preferably, the outer ring of the handle is covered with an anti-slip rubber sleeve, and the size of the mounting block is larger than the size of the mounting hole of the sealing screw.

[0014] Preferably, the sealing cylinder, sealing block, sealing screw, connecting rod, sealing pressure plate, and connecting threaded seat are made of stainless steel, and the lower wall thickness of the sealing cylinder is less than the upper wall thickness.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a combination of a sealing screw, a connecting rod, a sealing block, a sealing cylinder, and an expansion groove to expand the sealing cylinder from the inside out, ensuring a tight fit between its outer wall and the borehole opening. This eliminates the need for heavy hammering, reducing the probability of damage, while also reducing labor intensity and improving work efficiency. Furthermore, the sealing cylinder and sealing pressure plate are made of stainless steel, preventing rust during borehole sealing and ensuring a long service life.

[0017] By setting a sealing ring and rubber outer skin in conjunction with the plugging cylinder, the rubber outer skin contacts the borehole wall after sealing, which can increase the friction and reduce the probability of the plugging cylinder slipping out of the borehole. In addition, the sealing ring can increase the sealing performance between the plugging pressure plate and the plugging hole, further reducing the probability of groundwater leakage and improving the sealing effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-4 A device for plugging drill holes includes a plugging cylinder 1, a plugging pressure plate 2 fixedly connected to the top of the plugging cylinder 1, a connecting threaded seat 3 fixedly installed at the center of the top of the plugging pressure plate 2, and a plugging screw 4 disposed at the center of the upper and lower ends of the connecting threaded seat 3 and the plugging pressure plate 2.

[0026] See Figure 2 and Figure 3 Furthermore, a connecting rod 5 is fixedly installed at the bottom end of the sealing screw 4, and a sealing block 6 is installed at the bottom end of the connecting rod 5 through a connecting bolt 7. The sealing screw 4 and the sealing pressure plate 2 are rotatably connected, and the sealing screw 4 and the connecting threaded seat 3 are threadedly connected. A nut head 8 is fixedly connected to the upper position of the outer ring of the sealing screw 4. Expansion grooves 12 that are compatible with the sealing block 6 are provided on both sides of the sealing cylinder 1 at the lower position. The diameter of the sealing block 6 is larger than the inner diameter of the sealing cylinder 1. An installation hole is provided at the upper position of the front and rear ends of the sealing screw 4, and a handle 9 is movably installed in the installation hole. The front and rear ends of the handle 9 are threadedly connected to the installation block 10. The outer ring of the handle 9 is covered with an anti-slip rubber sleeve. The size of the installation block 10 is larger than the size of the installation hole of the sealing screw 4.

[0027] Specifically, when it is necessary to seal the borehole, firstly, the sealing block 6 can be installed below the connecting rod 5 using the connecting bolt 7. Then, the sealing cylinder 1 and the sealing block 6 can be inserted into the borehole as needed. Afterward, the sealing screw 4 can be rotated by using a tool or by installing the handle 9 on the top of the sealing screw 4. Since the sealing screw 4 is threaded onto the connecting thread seat 3, it can drive the connecting rod 5 to move into the sealing cylinder 1. Since the sealing cylinder 1 is provided with an expansion groove 12, the sealing cylinder 1 can be expanded outward by retracting the connecting rod 5 into the sealing cylinder 1, so as to fix the sealing cylinder 1 on the inner wall of the borehole that needs to be sealed, thus completing the sealing process. Afterward, the mounting block 10 can be unscrewed to remove the handle 9 as needed.

[0028] Example 2

[0029] See Figure 2 and Figure 4 Furthermore, based on Embodiment 1, the outer ring of the sealing cylinder 1 is further provided with a rubber outer skin 11, a sealing groove is provided at the upper position of the outer ring of the sealing cylinder 1, and a connecting thread seat 3 is provided in the sealing groove. The upper part of the sealing block 6 is tapered, and the sealing block 6 is detachably connected to the connecting rod 5 by the connecting bolt 7. The sealing cylinder 1, sealing block 6, sealing screw 4, connecting rod 5, sealing pressure plate 2, and connecting thread seat 3 are made of stainless steel. The lower wall thickness of the sealing cylinder 1 is less than the upper wall thickness.

[0030] Specifically, when the sealing cylinder 1 is in contact with the borehole, the rubber outer skin 11 on the outer ring of the sealing cylinder 1 can increase the friction between the sealing cylinder 1 and the borehole, reducing the probability of the sealing cylinder 1 detaching upwards, thereby improving the sealing effect. In addition, the sealing cylinder 1, the connecting rod 5, and the sealing screw 4 are all made of stainless steel, which can prevent rusting during the sealing process and improve service life. At the same time, a sealing ring 13 is provided at the connection between the sealing pressure plate 2 and the sealing cylinder 1, which can further improve the sealing performance between the sealing cylinder 1 and the borehole and reduce the probability of groundwater leakage.

[0031] In actual operation, the steps of adjusting the hole according to the sealing size in the existing technology will not be repeated here. When it is necessary to seal the drill hole, the sealing block 6 can be installed below the connecting rod 5 by connecting bolt 7. Then, the sealing cylinder 1 and the sealing block 6 can be inserted into the drill hole as needed. Then, a tool can be used or the handle 9 can be installed on the top of the sealing screw 4 so as to rotate the sealing screw 4. Since the sealing screw 4 is threaded on the connecting thread seat 3, the connecting rod 5 can be driven to move into the sealing cylinder 1.

[0032] Because the sealing cylinder 1 is provided with an expansion groove 12, the sealing cylinder 1 can be expanded outward by the connecting rod 5 being drawn into the sealing cylinder 1, so as to fix the sealing cylinder 1 on the inner wall of the borehole to be sealed and complete the sealing process. Subsequently, the mounting block 10 can be unscrewed as needed to remove the handle 9.

[0033] When the sealing cylinder 1 is in contact with the borehole, the rubber outer skin 11 on the outer ring of the sealing cylinder 1 can increase the friction between the sealing cylinder 1 and the borehole, reducing the probability of the sealing cylinder 1 detaching upwards, thereby improving the sealing effect. In addition, the sealing cylinder 1, the connecting rod 5, and the sealing screw 4 are all made of stainless steel, which can prevent rust during the sealing process and improve service life. At the same time, a sealing ring 13 is provided at the connection between the sealing pressure plate 2 and the sealing cylinder 1, which can further improve the sealing performance between the sealing cylinder 1 and the borehole and reduce the probability of groundwater leakage.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
