Description

Technical Field

[0001] This utility model relates to the field of open-pit blasting technology, specifically to a water-rich blast hole squeezing and drainage device for open-pit mines. Background Technology

[0002] Blasting holes are the core component of mining blasting operations. By loading explosives, they break up the rock mass, providing the necessary conditions for ore extraction, tunnel excavation, and bench formation. However, due to the open-pit blasting environment, precipitation often causes water accumulation within the blast holes, leading to changes or cancellations in blasting plans. Existing integrated rock drilling rigs combine the air compressor and drilling machine into one unit, making it impossible to use high-pressure airflow to drain the water from the hole. This affects the performance of explosives during water-bearing blasting operations and can cause detonation accidents. Therefore, we propose a squeezing and drainage device for water-rich blast holes in open-pit mines. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a water-rich blast hole squeezing drainage device for open-pit mines. This device is installed on the lower side of the impactor of an integrated down-the-hole rock drill rig via a threaded pipe at the upper end. The impactor can drive the conical impact pile deep into the blast hole, using pressure to expel the water accumulated at the bottom of the hole through the drainage hole and water pipe, thereby solving problems such as poor blasting effect and broken blasting caused by water accumulation in the blast hole. The wall-adhering sealing ring can fit tightly against the blast hole wall and deform under the action of friction on the inner wall of the blast hole, maintaining a tight fit, thus ensuring that the conical impact pile effectively generates pressure on the water when it is pressed down. It also has a locking component for the wall-adhering sealing ring, which facilitates the installation of the wall-adhering sealing ring and prevents the wall-adhering sealing ring from slipping off the mounting block due to friction on the inner wall of the blast hole. Through the opening of the disassembly and assembly slot, tools such as screwdrivers or pry bars can be inserted to disengage the locking ring from the locking block, thereby reducing the difficulty of disassembly and facilitating the replacement of the wall-adhering sealing ring after long-term wear. This effectively solves the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-rich blast hole squeezing drainage device for open-pit mines, comprising a conical impact pile, an installation block, drainage holes, a wall-adhering sealing ring, and a snap-fit ​​ring. The lower end of the conical impact pile is conical, and the upper end is cylindrical. A circular installation block is concentrically fixed to the upper end of the conical impact pile. A wall-adhering sealing ring is installed and fixed on the outer side of the installation block. The wall-adhering sealing ring is made of flexible silicone material. An annular snap-fit ​​ring is integrally fixed to the upper port of the wall-adhering sealing ring. The snap-fit ​​ring is tightly fitted around the outer circumference of the installation block. The upper edge of the conical impact pile is chamfered. The wall-adhering sealing ring is annular with its outer edge tilted downwards. Two vertical drainage holes are opened inside the conical impact pile.

[0005] By installing this device under the impactor of an integrated down-the-hole rock drill, the impactor can drive the conical impact pile deep into the blast hole. The pressure forces the water accumulated at the bottom of the hole out through the drainage hole. The wall-adhering sealing ring can fit tightly against the blast hole wall, preventing high-pressure water from leaking out from the periphery of the conical impact pile and thus effectively avoiding adverse effects on the drainage of accumulated water. The wall-adhering sealing ring, made of flexible silicone material, allows its outer edge to move flexibly. Therefore, under the action of friction with the inner wall of the blast hole, the outer edge of the wall-adhering sealing ring can be flipped up or down to deform, thus always maintaining a tight fit with the inner wall of the blast hole.

[0006] Furthermore, the device also includes locking blocks. Two centrally symmetrically distributed locking blocks are fixedly connected to the outer circumference of the mounting block. The snap-fit ​​ring has two centrally symmetrically distributed slots inside. The two locking blocks respectively engage with the slots of the snap-fit ​​ring. The upper end of each locking block has a chamfered structure on its outward-facing side. By tightening the snap-fit ​​ring onto the outer side of the mounting block, the wall-mounted sealing ring can be installed. The locking blocks can lock and limit the snap-fit ​​ring, preventing the friction of the borehole wall from causing the wall-mounted sealing ring to slip off the mounting block. The chamfered structure on the outer upper end of the locking blocks reduces the resistance received during installation, facilitating the sliding installation of the snap-fit ​​ring.

[0007] Furthermore, it also includes a disassembly slot. A disassembly slot is provided at the upper edge of the conical impact pile, corresponding vertically to each locking block. The depth of the disassembly slot is greater than the horizontal distance between the mounting block and the edge of the conical impact pile. The disassembly slot is used for inserting tools such as screwdrivers or pry bars, allowing the retaining ring to be disassembled from the locking block during disassembly or assembly. This reduces the difficulty of disassembly and facilitates the replacement of worn retaining rings after long-term use.

[0008] Furthermore, it also includes a threaded nozzle, with a concentric annular threaded nozzle section fixedly connected to the upper end of the mounting block. The threaded nozzle is used for threaded connection with the impactor of the integrated down-the-hole rock drill, thereby fixing the device to the lower end of the impactor.

[0009] Furthermore, it also includes sleeve interfaces. Two sleeve interfaces are fixedly connected to the upper end of the mounting block, and the drain hole extends upward through the mounting block, communicating with the interior of one of the sleeve interfaces. The sleeve interfaces are used for connecting the drain pipe, allowing water passing through the drain hole to be transported upward and ultimately discharged from the borehole.

[0010] Furthermore, it also includes a pressure sensor. A circular mounting groove is formed at the lower tip of the conical impact pile, and a pressure sensor is installed inside the groove. A battery and a data transmission device, compatible with the pressure sensor, are embedded inside the conical impact pile. The pressure sensor monitors the water pressure reaction force experienced by the conical impact pile during downward pressing and transmits this data to the control room of the integrated down-the-hole rock drilling rig via the data transmission device, thus facilitating operator control of the impactor's diving depth each time.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This open-pit mine water-rich blast hole squeezing drainage device has the following advantages:

[0012] 1. This device is installed on the lower side of the impactor of the integrated down-the-hole rock drilling rig. The impactor can drive the conical impact pile deep into the blast hole. It uses pressure to discharge the water accumulated at the bottom of the hole through the drainage hole and water pipe, thereby solving the problems of poor blasting effect and broken blasting caused by water accumulation in the blast hole. The wall sealing ring can fit tightly with the blast hole wall and deform under the action of friction on the inner wall of the blast hole to maintain tightness, thereby ensuring that the conical impact pile can effectively generate water pressure when it is pressed down.

[0013] 2. It has a retaining component for the wall-mounted sealing ring, which facilitates the installation of the wall-mounted sealing ring and prevents the wall-mounted sealing ring from slipping off the mounting block due to the friction of the inner wall of the borehole. Through the opening of the disassembly and assembly slot, a screwdriver or pry bar can be inserted to disengage the retaining ring from the retaining block, thereby reducing the difficulty of disassembly and facilitating the replacement of the wall-mounted sealing ring after long-term use and wear.

[0014] 3. This utility model is installed on the lower side of the impactor of an integrated down-the-hole rock drilling rig. The impactor can drive the conical impact pile deep into the blast hole, using pressure to discharge the water accumulated at the bottom of the hole through the drainage hole and water pipe, thereby solving the problems of poor blasting effect and broken blasting caused by water accumulation in the blast hole. The wall-adhering sealing ring can fit tightly with the blast hole wall and deform under the action of friction on the inner wall of the blast hole to maintain tightness, thereby ensuring that the conical impact pile effectively generates water pressure when it is pressed down. It also has a locking component for the wall-adhering sealing ring, which facilitates the installation of the wall-adhering sealing ring and prevents the wall-adhering sealing ring from slipping off the mounting block due to friction on the inner wall of the blast hole. Through the opening of the disassembly and assembly slot, a screwdriver or pry bar can be inserted to disengage the locking ring from the locking block, thereby reducing the difficulty of disassembly and facilitating the replacement of the wall-adhering sealing ring after long-term use and wear.

[0019] 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.

[0020] Please see Figures 1-3 This embodiment provides a technical solution: an open-pit mine water-rich blast hole squeezing drainage device, including a conical impact pile 1, an mounting block 2, a drainage hole 3, a wall-adhering sealing ring 5, and a snap-fit ​​rubber ring 6. The lower end of the conical impact pile 1 is a conical structure, and the upper end of the conical impact pile 1 is a cylindrical structure. A circular mounting block 2 is concentrically fixed to the upper end of the conical impact pile 1. A wall-adhering sealing ring 5 is installed and fixed on the outer side of the mounting block 2. The wall-adhering sealing ring 5 is made of flexible silicone material. An annular snap-fit ​​rubber ring 6 is integrally fixed to the upper port of the wall-adhering sealing ring 5. The snap-fit ​​rubber ring 6 is tightly fitted on the outer circumference of the mounting block 2. The upper edge of the conical impact pile 1 is processed with a chamfered structure. The wall-adhering sealing ring 5 is an annular structure with its outer edge inclined downward. Two vertical drainage holes 3 are opened inside the conical impact pile 1.

[0021] By installing this device under the impactor of the integrated down-the-hole rock drill, the impactor can drive the conical impact pile 1 deep into the blast hole. The pressure is used to discharge the water accumulated at the bottom of the hole through the drainage hole 3. The wall-adhering sealing ring 5 can fit tightly against the blast hole wall, preventing high-pressure water from being discharged from the periphery of the conical impact pile 1 and thus effectively avoiding adverse effects on the drainage of accumulated water. The wall-adhering sealing ring 5, made of flexible silicone material, allows its outer edge to be flexibly flipped. Therefore, under the action of friction with the inner wall of the blast hole, the outer edge of the wall-adhering sealing ring 5 can be flipped up or down to deform, thus always maintaining a tight fit with the inner wall of the blast hole.

[0022] It also includes locking blocks 7. Two locking blocks 7 are fixedly connected to the outer circumference of the mounting block 2, and two locking slots are centrally symmetrically opened inside the locking ring 6. The two locking blocks 7 are respectively locked into the locking slots of the locking ring 6. The upper end of the locking block 7 has a chamfered structure on the outward side. By tightening the locking ring 6 on the outside of the mounting block 2, the wall-adhering sealing ring 5 can be installed. The locking blocks 7 can lock and limit the locking ring 6, preventing the friction of the inner wall of the borehole from causing the wall-adhering sealing ring 5 to slip off from the mounting block 2. Moreover, the chamfered structure on the outer side of the upper end of the locking block 7 can reduce the resistance received by the locking ring 6 when installing it, making it easier to slide the locking ring 6 into place.

[0023] It also includes a disassembly slot 8. A disassembly slot 8 is provided at the upper edge of the conical impact post 1, and at a position corresponding vertically to each locking block 7. The depth of the disassembly slot 8 is greater than the horizontal distance between the mounting block 2 and the edge of the conical impact post 1. The disassembly slot 8 is used for inserting tools such as screwdrivers or pry bars, so that when disassembling or assembling the wall-mounted sealing ring 5, the locking rubber ring 6 can be disengaged from the locking block 7 by inserting a tool, thereby reducing the difficulty of disassembly and facilitating the replacement of the wall-mounted sealing ring 5 after long-term wear.

[0024] It also includes a threaded pipe port 9, and a ring-shaped threaded pipe port 9 is concentrically fixed to the upper end of the mounting block 2. The threaded pipe port 9 is used to make a threaded connection with the impactor of the integrated down-the-hole rock drilling rig, thereby installing and fixing this device to the lower end of the impactor.

[0025] It also includes sleeve interfaces 4. The upper end of the mounting block 2 is fixedly connected to two sleeve interfaces 4, one on the left and one on the right. The drain hole 3 extends upward through the mounting block 2 and is connected to the interior of one of the sleeve interfaces 4. The sleeve interfaces 4 are used for connecting the drain pipe, so that the water passing through the drain hole 3 can be transported upward and finally discharged from the borehole.

[0026] It also includes a pressure sensor 10. A circular mounting groove is formed at the lower tip of the conical impact pile 1, and the pressure sensor 10 is installed inside the groove. A battery and a data transmission device, compatible with the pressure sensor 10, are embedded inside the conical impact pile 1. The pressure sensor 10 monitors the water pressure reaction force experienced by the conical impact pile 1 when it is pressed down, and transmits this data to the control room of the integrated down-the-hole rock drilling rig via the data transmission device, thus facilitating the operator's control of the impactor's diving depth each time.

[0027] The working principle of the water-rich blast hole squeezing drainage device provided by this utility model is as follows: This device is connected to the impactor of an integrated down-the-hole rock drill rig via a threaded pipe port 9 at the upper end. The device is then fixed to the lower end of the impactor. The impactor can drive the conical impact pile 1 deep into the blast hole, using pressure to discharge the water accumulated at the bottom of the hole through the drainage hole 3 and the water pipe. The sleeve interface 4 is used for connecting the drainage pipe, so that the water passing through the drainage hole 3 can be transported upward and finally discharged from the blast hole. This can solve the problems of poor blasting effect and broken blasting caused by water accumulation in the blast hole. The wall-adhering sealing ring 5 can fit tightly with the blast hole wall and deform under the action of friction on the inner wall of the blast hole to maintain tightness. This ensures that the cone-shaped impact pile 1 effectively generates water pressure when it is pressed down. By tightening the snap-fit ​​ring 6 onto the outside of the mounting block 2, the wall-mounted sealing ring 5 can be installed. The snap-fit ​​block 7 can lock and limit the snap-fit ​​ring 6, preventing the friction of the inner wall of the borehole from causing the wall-mounted sealing ring 5 to slip off from the mounting block 2. The chamfered structure on the upper outer side of the snap-fit ​​block 7 can reduce the resistance it receives when installing the snap-fit ​​ring 6, making it easier to slide the snap-fit ​​ring 6 into place. The disassembly slot 8 is used for inserting tools such as screwdrivers or pry bars, so that when disassembling and assembling the wall-mounted sealing ring 5, the snap-fit ​​ring 6 can be separated from the snap-fit ​​block 7 by inserting tools, thereby reducing the difficulty of disassembly and facilitating the replacement of the wall-mounted sealing ring 5 after long-term wear. In addition, a pressure sensor 10, a matching battery, and a data transmission device are embedded in the lower end of the cone-shaped impact pile 1. The pressure sensor 10 is used to monitor the water pressure reaction force when the cone-shaped impact pile 1 is pressed down, and the data is transmitted to the control room of the integrated down-the-hole rock drilling rig through the data transmission device, so that the operator can control the diving depth of the impactor each time.

[0028] It is worth noting that the input terminals of the pressure sensor 10 and the matching data transmission device disclosed in the above embodiments are electrically connected to the output terminal of the battery embedded in the cone impact pile 1 through an external control switch group. The control switch group controls the operation of the pressure sensor 10 and the data transmission device using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
