Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an auxiliary device for manufacturing blast hole filling material. Background Technology

[0002] In hard rock engineering excavation, drill-and-blast is a traditional and widely used construction method. Its core objective is to efficiently and precisely break the rock to advance the project schedule and ensure construction quality. However, the effective utilization of explosive energy remains a key factor limiting the effectiveness and cost of drill-and-blast construction.

[0003] Numerous studies have shown that borehole plugging is crucial for improving the utilization rate of explosive energy. Borehole plugging effectively increases the energy propagated by stress waves, promoting the formation of more and longer radial cracks within the rock, thereby significantly improving blasting results. Conversely, if the borehole is not plugged, the explosive gases will rapidly escape through the orifice, carrying away approximately 50% of the explosive energy, resulting in energy waste. This also affects the degree of rock fragmentation and blasting quality, increasing engineering and time costs.

[0004] In the process of making the borehole packing material, a suction cup is used to adsorb the sealing plug, and then the sealing plug is moved and inserted into the PVC pipe to complete the sealing of the PVC pipe. However, when the suction cup is separated from the sealing plug, the water in the underwater environment will block the flow of gas, and the vacuum cavity formed after pressing cannot draw in air; moreover, the external water pressure continues to increase the suction force, causing the sealing plug to be locked on the suction cup. External force pulling can easily damage or deform the sealing plug, thereby compromising the sealing integrity of the PVC pipe. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for manufacturing borehole filling material. This device solves the problem that when the suction cup and the sealing plug are separated, the water in the underwater environment blocks the flow of gas, and the vacuum cavity formed after pressing cannot draw in air. Furthermore, the external water pressure continuously increases the suction force, causing the sealing plug to be locked on the suction cup. External pulling can easily damage or deform the sealing plug, thereby compromising the sealing integrity of the PVC pipe.

[0006] To achieve the above objectives, this utility model provides an auxiliary device for manufacturing borehole filling material, comprising: a power source, a connecting rod, an mounting cylinder, and a suction cup. The movable end of the power source is connected to the connecting rod, one end of the connecting rod is slidably connected inside the mounting cylinder, and the end of the mounting cylinder is fixedly connected to the suction cup. The suction cup is used to adsorb the sealing plug.

[0007] Both the suction cup and the mounting cylinder have vent holes at their connecting ends. A sealing gasket for sealing the vent holes is fixedly connected to the end of the connecting rod. A sliding groove is provided on the inner wall of the mounting cylinder. A slider that matches the sliding groove is fixedly connected to the connecting rod. The slider is slidably connected in the sliding groove. A first spring is provided between the sliding groove and the slider. One end of the first spring is fixedly connected to the inner wall of the sliding groove away from the suction cup, and the other end of the first spring is fixedly connected to the slider.

[0008] This design allows water to enter the suction cup through the vent hole via the relative sliding between the connecting rod and the mounting cylinder, thus easily and quickly separating the suction cup from the sealing plug; and the elastic deformation of the first spring allows the connecting rod to return to its original position within the mounting cylinder for future use.

[0009] Furthermore, it also includes a water injection tank and a positioning channel. The positioning channel is fixedly installed on one side of the water injection tank. The moving end of the power source passes through one side of the water injection tank and is located within the positioning channel. The moving end of the power source is fixedly connected to the end of the connecting rod away from the mounting cylinder.

[0010] Furthermore, a limiting component is installed in the positioning channel. The limiting component is used to laterally limit the sealing plug. A pressure sensor is fixedly installed on the contact surface between the limiting component and the sealing plug.

[0011] Furthermore, the limiting component includes a guide block and a second spring. Two guide blocks are symmetrically arranged at the top of the positioning channel. A guide telescopic rod is fixedly connected between the guide block and the positioning channel. The second spring is sleeved on the guide telescopic rod. One end of the second spring is fixedly connected to the positioning channel, and the other end of the second spring is fixedly connected to the guide block. The moving direction of the two guide blocks forms an acute angle with the central axis of the positioning channel.

[0012] Furthermore, the power source is a hydraulic cylinder, and the piston of the hydraulic cylinder passes through the water tank and is fixedly connected to one end of the connecting rod.

[0013] Furthermore, a storage frame is fixedly connected to the top of the positioning channel, and the storage frame is fixedly installed on the water injection tank. The storage frame stores a plurality of the sealing plugs.

[0014] Furthermore, symmetrical adjustment plates are arranged on both sides inside the storage frame, and a third spring is provided between the adjustment plate and the inner wall of the storage frame. The moving direction of the adjustment plate is perpendicular to the central axis of the positioning channel. Multiple sealing plugs are vertically arranged inside the storage frame, and the sealing plugs abut against the contact surfaces of the adjustment plate and the storage frame.

[0015] Furthermore, the outer diameter of the portion of the connecting rod located outside the mounting cylinder is equal to the outer diameter of the piston of the hydraulic cylinder and the outer diameter of the mounting cylinder.

[0016] Furthermore, the maximum outer diameter of the suction cup is less than or equal to the maximum outer diameter of the minimum sealing plug and the outer diameter of the mounting cylinder.

[0017] The beneficial effects of this embodiment are as follows:

[0018] The relative sliding between the connecting rod and the mounting cylinder allows water to enter the suction cup through the vent hole, thereby achieving easy and quick separation of the suction cup and the sealing plug; and the elastic deformation of the first spring allows the connecting rod and the mounting cylinder to return to their original positions for future use.

[0025] The specific embodiments of this utility model will be described in detail below. It should be noted that the embodiments described herein are for illustrative purposes only and are not intended to limit the utility model. In the following description, numerous specific details are set forth in order to provide a thorough understanding of this utility model. However, it will be apparent to those skilled in the art that these specific details are not necessary to implement this utility model.

Therefore, the phrases "in an embodiment," "in an embodiment," "an example," or "an example" appearing in various places throughout the specification do not necessarily refer to the same embodiment or example. Furthermore, specific features, structures, or characteristics can be combined in any suitable combination and / or sub-combination in one or more embodiments or examples. Moreover, those skilled in the art will understand that the illustrations provided herein are for illustrative purposes and are not necessarily drawn to scale.

[0027] Please see Figure 1 This utility model provides an embodiment of an auxiliary device for making borehole filling material, including: a power source, a connecting rod 31, an mounting cylinder 30, and a suction cup 3. The movable end of the power source is connected to the connecting rod 31. One end of the connecting rod 31 is slidably connected inside the mounting cylinder 30. The end of the mounting cylinder 30 is sealed to the suction cup 3. The suction cup 3 is used to adsorb the sealing plug 1. Vent holes 34 are provided at the connecting ends of the suction cup 3 and the mounting cylinder 30. A sealing gasket 35 for sealing the vent holes 34 is fixedly connected to the end of the connecting rod 31. A sliding groove is provided on the inner wall of the mounting cylinder 30. A slider 32 that matches the sliding groove is fixedly connected to the connecting rod 31. The slider 32 is slidably connected inside the sliding groove. A first spring 33 is provided between the sliding groove and the slider 32. One end of the first spring 33 is fixedly connected to the inner wall of the sliding groove away from the suction cup 3, and the other end of the first spring 33 is fixedly connected to the slider 32. When the suction cup 3 disengages from the sealing plug 1, the power source is activated, causing the connecting rod 31 to retract backward. At this time, the sealing plug 1 is secured within the PVC pipe, preventing the suction cup 3 from moving backward with the connecting rod 31. Therefore, the connecting rod 31 moves along the groove via the slider 32, causing relative displacement with the mounting cylinder 30. This separates the sealing gasket 35 from the vent hole 34, allowing water to flow through the gap between the mounting cylinder 30 and the connecting rod 31 into the vent hole 34, thus entering the suction cup 3 and separating it from the rigid circular plate. This allows the suction cup 3 to smoothly return to its original position for future use. Simultaneously, as the slider 32 retracts with the connecting rod 31, it compresses the first spring 33. After the suction cup 3 separates from the rigid circular plate, the mounting cylinder 30 moves with the connecting rod 31. At this point, under the elastic deformation of the first spring 33, the slider 32 returns to its original position, causing the sealing gasket 35 to press against the vent hole 34 again, facilitating future use.

[0028] Please see Figure 1In this embodiment, a water injection tank 2 and a positioning channel 24 are also included. The positioning channel 24 is fixedly installed on one side of the water injection tank 2. The moving end of the power source passes through one side of the water injection tank 2 and is located inside the positioning channel 24. The moving end of the power source is fixedly connected to the end of the connecting rod 31 away from the mounting cylinder 30. The moving direction of the suction cup 3 is determined, and the suction cup 3 is constrained to a certain extent by the positioning channel 24, thereby improving the accuracy of the insertion of the sealing plug 1.

[0029] Please see Figure 2 In this embodiment, a limiting component is installed in the positioning channel 24. The limiting component is used to laterally limit the sealing plug 1. A pressure sensor is fixedly installed on the contact surface between the limiting component and the sealing plug 1. The limiting component provides a certain forward resistance to the sealing plug 1, which facilitates the suction cup 3 to be smoothly adsorbed onto the sealing plug 1. At the same time, the pressure sensor detects whether the sealing plug 1 is located in the exact center of the positioning channel 24.

[0030] Please see Figure 2 In this embodiment, the limiting component includes a guide block 27 and a second spring 25. Two guide blocks 27 are symmetrically arranged at the top of the positioning channel 24. A guide telescopic rod 26 is fixedly connected between the guide blocks 27 and the positioning channel 24. The second spring 25 is sleeved on the guide telescopic rod 26. One end of the second spring 25 is fixedly connected to the positioning channel 24, and the other end of the second spring 25 is fixedly connected to the guide block 27. The moving direction of the two guide blocks 27 forms an acute angle with the central axis of the positioning channel 24. This facilitates the adaptation to sealing plugs 1 of different diameters. At the same time, it applies a downward push to the sealing plug 1 located on the positioning channel 24, further limiting the sealing plug 1. The guide telescopic rod 26 can prevent the guide block 27 from not moving back and forth when the sealing plug 1 moves forward under the push of the piston of the hydraulic cylinder 20. Instead, it applies a forward resistance to the moving sealing plug 1 so as to press the suction cup 3 onto the sealing plug 1.

[0031] Please see Figure 1 In this embodiment, the power source is a hydraulic cylinder 20, and the piston of the hydraulic cylinder 20 is fixedly connected to one end of the connecting rod 31 through the water tank 2. The piston directly passes through the water tank 2, seamlessly transmitting hydraulic power to the connecting rod 31, avoiding energy loss in the power conversion process in traditional designs, and ensuring maximum power transmission efficiency; the viscosity of the hydraulic oil can absorb the impact and vibration during piston movement, making the movement of the connecting rod 31 more stable.

[0032] Please see Figure 1-2 In this embodiment, a storage frame 21 is fixedly connected to the top of the positioning channel 24. The storage frame 21 is fixedly installed on the water tank 2, and multiple sealing plugs 1 are stored inside the storage frame 21. This achieves automated material feeding and improves work efficiency.

[0033] Please see Figure 1-2In this embodiment, adjusting plates 22 are symmetrically arranged on both sides of the storage frame 21. A third spring 23 is provided between the adjusting plates 22 and the inner wall of the storage frame 21. The moving direction of the adjusting plates 22 is perpendicular to the central axis of the positioning channel 24. Multiple sealing plugs 1 are vertically arranged in the storage frame 21, and the sealing plugs 1 abut against the contact surfaces of the adjusting plates 22 and the storage frame 21. In use, multiple sealing plugs 1 can be stored in the storage frame 21. The two ends of the sealing plugs 1 abut against the inner walls of the storage frame 21 on both sides, and the cylindrical sides of the sealing plugs 1 abut against the adjusting plates 22, so that the sealing plugs 1 do not tilt or move arbitrarily. At the same time, by utilizing the elasticity of the third spring 23 and the movement of the adjusting plates 22, the storage frame 21 can accommodate sealing plugs 1 of different diameters to complete the sealing work of PVC pipes of different diameters.

[0034] Please see Figure 2 In this embodiment, the outer diameter of the portion of the connecting rod 31 outside the mounting cylinder 30 is equal to the outer diameter of the piston of the hydraulic cylinder 20 and the outer diameter of the mounting cylinder 30. This facilitates the piston driving the connecting rod 31 and the mounting cylinder 30 to move normally within the positioning channel 24, avoiding jamming with the bottom sealing plug 1 inside the storage frame 21, which would prevent movement.

[0035] Please see Figure 2-3 In this embodiment, the maximum outer diameter of the suction cup 3 is less than or equal to the maximum outer diameter of the smallest sealing plug 1 and the outer diameter of the mounting cylinder 30. This reduces friction between the suction cup 3 and the bottommost sealing plug 1 in the storage frame 21 during movement, thereby reducing wear on the suction cup 3 and extending its service life.

[0036] Please see Figure 2 In this embodiment, one end of the sealing plug 1 is cylindrical, and the other end is conical. The diameter of the cylinder is equal to the maximum diameter of the cone. The diameter of the end of the cone connected to the cylinder is greater than the inner diameter of the PVC pipe and equal to the outer diameter of the PVC pipe. The diameter of the end of the cone is smaller than the inner diameter of the PVC pipe. The conical shape facilitates the easy insertion of the sealing plug 1 into the PVC pipe, completing the sealing of the end of the PVC pipe. In this embodiment, a rigid circular plate 11 is fixedly connected to the end of the cylinder. An installation groove is opened in the cylinder, and a weight column 10 is set in the installation groove. The central axis of the weight column 10 is parallel to the central axis of the sealing plug 1. A certain length of cylindrical shape is retained on the sealing plug 1, which cooperates with the rigid circular plate 11 and the weight column 10, so that multiple sealing plugs 1 are not easy to roll when placed vertically, avoiding the situation where the sealing plug 1 tilts due to the influence of water flow during the sealing process, thus making subsequent positioning unusable. In actual use, the length ratio of the cylinder to the cone can be set as needed.

[0037] Please see Figure 2In this embodiment, a groove 12 is formed at the end of the cone, and an elastic membrane 13 is sealed on the surface of the groove 12. In an underwater environment, there may be high water pressure inside the PVC pipe. When the high-pressure water flow impacts the front end of the cone, the sealed groove 12 acts like an elastic buffer chamber. The elastic membrane 13 has a certain degree of flexibility and elasticity, and it can deform under water pressure to absorb and disperse part of the impact force of the water flow. At the same time, there is a water pressure difference between the inside and outside of the underwater PVC pipe, which may affect the insertion of the cone. The sealed groove 12 can balance the water pressure inside and outside the pipe. When the water pressure inside the pipe is greater than that outside the pipe, the elastic membrane 13 will bulge slightly outward, creating a certain space in the groove 12 to accommodate part of the high-pressure water flow and alleviate the direct pressure of the water pressure inside the pipe on the cone; conversely, when the water pressure outside the pipe is greater, the membrane will indent inward, reducing the obstruction of the external water pressure on the insertion of the cone.

[0038] The specific usage method of this embodiment is as follows:

[0039] In use, start the hydraulic cylinder 20. The piston of the hydraulic cylinder 20 drives the connecting rod 31, the mounting cylinder 30 and the suction cup 3 to move forward until the suction cup 3 is attached to the sealing plug 1. Then push the sealing plug 1 to move until the sealing plug 1 is inserted into the PVC pipe and sealed tightly.

[0040] When the suction cup 3 disengages from the sealing plug 1, the hydraulic cylinder 20 is activated, causing the piston of the hydraulic cylinder 20 to retract the connecting rod 31 backward. At this time, the sealing plug 1 is locked inside the PVC pipe, preventing the suction cup 3 from moving backward with the connecting rod 31. Therefore, the connecting rod 31 moves relative to the mounting cylinder 30 via the movement of the slider 32 along the groove, causing the sealing gasket 35 to separate from the vent hole 34. Water flows into the vent hole 34 through the gap between the mounting cylinder 30 and the connecting rod 31, entering the interior of the suction cup 3, causing the suction cup 3 to separate from the rigid circular plate, and thus smoothly returning the suction cup 3 to its original position for future use. Simultaneously, when the slider 32 retracts backward with the connecting rod 31, it compresses the first spring 33. After the suction cup 3 separates from the rigid circular plate, the mounting cylinder 30 moves with the connecting rod 31. At this time, under the elastic deformation of the first spring 33, the slider 32 returns to its original position, causing the sealing gasket 35 to press against the vent hole 34 again for future use.

[0041] In summary, this invention achieves easy and quick separation of the suction cup 3 from the sealing plug 1 by allowing water to enter the suction cup 3 through the vent hole 34 through the relative sliding between the connecting rod 31 and the mounting cylinder 30. Furthermore, the elastic deformation of the first spring 33 allows the connecting rod 31 to return to its original position within the mounting cylinder 30 for future use. Therefore, this invention effectively overcomes the various shortcomings of the prior art.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
