Description

Technical Field

[0001] This utility model belongs to the field of blasting engineering technology, and in particular relates to a high-pressure gas segmented blasting generating device. Background Technology

[0002] High-pressure gas blasting generators, as a type of non-explosive blasting equipment, are widely used in mining, tunneling, and urban demolition due to their environmental protection, safety, and strong controllability.

[0003] However, existing high-pressure gas blasting devices generally lack effective positioning structures. In actual use, when the blasting device is inserted into the blasting hole, if the blasting hole diameter is too large or the anchoring structure of the blasting device fails, the blasting device cannot be firmly fixed and may shift. Once shifted, the direction of the impact force generated by the blast will be difficult to control, which will not only reduce the blasting effect but also cause the depressurization direction to deviate from the expected direction. When the high-pressure gas is released, a reverse thrust may be generated.

[0004] To address these issues, we provide a high-pressure gas segmented explosion generating device. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure gas segmented blasting device. By using a positioning component, it solves the problem that existing high-pressure gas blasting devices do not have an effective positioning structure, making it impossible to firmly fix the blasting device in the blast hole, and the blasting device may shift during blasting.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-pressure gas segmented explosion generating device, comprising a liquid storage cylinder, a plug on one side of the liquid storage cylinder, a controller on one side of the plug, an excitation tube on one side of the controller, a positioning component on one side of the surface of the liquid storage cylinder, and an expansion tube at the end of the liquid storage cylinder away from the plug. The positioning component includes a slot formed on the surface of the liquid storage cylinder, a retaining plate movably connected to the inner cavity of the slot, an mounting sleeve fixedly connected to one side of the retaining plate, and screws movably connected to both sides of the mounting sleeve. Threaded tubes are threadedly connected to the surface of the screws, and a clamping arc-shaped plate is movably connected to one end of the threaded tube.

[0008] The present invention is further configured such that a fastening bolt is threadedly connected to the surface of the mounting sleeve, one end of the fastening bolt is threadedly connected to the bolt hole on the surface of the card plate, and after the card plate is inserted into the inner cavity of the card slot, the fastening bolt is screwed until one end is screwed into the bolt hole on the surface of the card plate, thereby fixing the card plate in the inner cavity of the card slot.

[0009] The present invention is further configured such that an anti-slip plate is fixedly connected to the side of the pressing arc plate away from the threaded tube, and the surface of the anti-slip plate is provided with anti-slip texture. The anti-slip plate has good anti-slip properties on one side, so that the pressing arc plate is not easy to slip when it presses against the inner wall of the blast hole.

[0010] The present invention is further configured such that the top and bottom of one side of the pressing arc plate are movably connected to limit rods, and the end of the limit rod away from the pressing arc plate is movably connected to the surface of the fixed sleeve. The limit rod swings as the pressing arc plate moves, and the pressing arc plate is limited by the two sets of limit rods, so that the pressing arc plate is more stable when it moves.

[0011] The present invention is further configured such that a sealing ring is fixedly connected to one side of the plug, the diameter of the sealing ring being adapted to the inner diameter of the liquid storage cylinder, and the sealing ring being inserted into the inner cavity of the liquid storage cylinder as the plug is installed on one side of the liquid storage cylinder, thereby improving the connection and sealing performance between the plug and the liquid storage cylinder.

[0012] The present invention is further configured such that a threaded cylinder is fixedly connected to one side of the plug, and a threaded groove is provided on one side of the liquid storage cylinder. When the plug is rotated, the plug drives the threaded cylinder to rotate so that it is screwed into the threaded groove on one side of the liquid storage cylinder, thereby fixing the plug to one end of the liquid storage cylinder.

[0013] The present invention is further provided that a handle is fixedly connected to one side of the plug. The handle is made of stainless steel, which makes it more convenient to rotate the plug and lift the plug for movement.

[0014] The present invention is further configured such that a turntable is fixedly connected to the surface of the threaded tube, and an anti-slip rod is fixedly connected to the surface of the turntable. Several anti-slip rods are provided on the surface of the turntable, making it more convenient and easier to rotate the threaded tube by the turntable.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model can adapt to blasting holes of different sizes. When the blasting hole is large, the mounting sleeve can be moved to insert the clamping plate into the groove on the surface of the liquid storage cylinder. Then, the device is inserted into the blasting hole. The threaded tube is rotated, and it rotates on the surface of the screw and moves axially, driving the abutting arc plate to move. The two abutting arc plates abut against the inner wall of the blasting hole respectively, thereby firmly fixing the blasting device in the blasting hole.

[0017] 2. This utility model uses a controller to activate the excitation tube to ignite the heating agent. The heat generated instantly creates high pressure in the gas. The high-pressure gas is discharged through the venting hole on the expansion tube, impacting the surrounding medium and causing it to rupture, thus achieving the purpose of blasting. At the same time, one end of the liquid storage cylinder is restricted and fixed by the positioning component, which prevents the liquid storage cylinder from shifting due to the impact force. This not only ensures the blasting effect but also enhances the safety of the blasting process to a certain extent. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5This utility model is a high-pressure gas segmented explosion generating device, including a liquid storage cylinder 1, a plug 2 on one side of the liquid storage cylinder 1, a controller 3 on one side of the plug 2, an excitation tube 4 on one side of the controller 3, a positioning component 5 on one side of the surface of the liquid storage cylinder 1, and an expansion tube 6 at the end of the liquid storage cylinder 1 away from the plug 2. The positioning component 5 includes a slot 501, which is formed on the surface of the liquid storage cylinder 1. A retaining plate 502 is movably connected to the inner cavity of the slot 501. An installation sleeve 503 is fixedly connected to one side of the retaining plate 502. Screws 504 are movably connected to both sides of the installation sleeve 503. A threaded tube 505 is threadedly connected to the surface of the screws 504. A clamping arc plate 506 is movably connected to one end of the threaded tube 505.

[0027] Specifically: If the blast hole has a large opening size, the mounting sleeve 503 can be moved until the clamping plate 502 on its inner wall is inserted into the clamping groove 501 on the surface of the liquid storage cylinder 1. Then, the blasting device is inserted into the blast hole. The threaded tube 505 is rotated. While the threaded tube 505 rotates on the surface of the screw 504, it will move along the axial direction of the screw 504, thereby driving the clamping arc plate 506 at one end to move to the two clamping arc plates 506 respectively to clamp the inner wall of the blast hole, thereby fixing the blasting device in the blast hole.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the surface of the mounting sleeve 503 is threaded with a fastening bolt, one end of which is threaded to the bolt hole on the surface of the clamping plate 502. An anti-slip plate is fixedly connected to the side of the pressing arc plate 506 away from the threaded tube 505. The surface of the anti-slip plate is provided with anti-slip texture. Limiting rods 7 are movably connected to the top and bottom of the side of the pressing arc plate 506. The end of the limiting rod 7 away from the pressing arc plate 506 is movably connected to the surface of the fixing sleeve. A sealing ring is fixedly connected to one side of the plug 2. The diameter of the sealing ring is adapted to the inner diameter of the liquid storage cylinder 1. A threaded cylinder 8 is fixedly connected to one side of the plug 2. A threaded groove 9 is opened on one side of the liquid storage cylinder 1. A handle is fixedly connected to one side of the plug 2. The handle is made of stainless steel. A turntable is fixedly connected to the surface of the threaded tube 505. An anti-slip rod is fixedly connected to the surface of the turntable.

[0030] Specifically: After the clamping plate 502 is inserted into the inner cavity of the clamping slot 501, the fastening bolt is tightened until one end is screwed into the bolt hole on the surface of the clamping plate 502, thereby fixing the clamping plate 502 in the inner cavity of the clamping slot 501. The anti-slip plate side has good anti-slip properties, making it less likely for the pressing arc plate 506 to slip against the inner wall of the blast hole. The limiting rod 7 swings as the pressing arc plate 506 moves. The two sets of limiting rods 7 limit the pressing arc plate 506, making the movement of the pressing arc plate 506 more stable and tight. The sealing ring is inserted into the inner cavity of the liquid storage cylinder 1 along with the plug 2 installed on one side, thereby improving the sealing performance between the plug 2 and the liquid storage cylinder 1. When the plug 2 is rotated, the plug 2 drives the threaded cylinder 8 to rotate and screw it into the threaded groove 9 on one side of the liquid storage cylinder 1, thereby fixing the plug 2 to one end of the liquid storage cylinder 1. It is more convenient to rotate the plug 2 and lift the plug 2 for movement by pulling the handle. Several anti-slip bars are set on the surface of the turntable, making it more convenient and easier to rotate the threaded tube 505 by the turntable.

[0031] The working principle of this utility model is as follows: The blasting device is transported to the blasting point, liquid carbon dioxide is filled into the inner cavity of the storage cylinder 1, and the plug 2 is installed at one end of the storage cylinder 1. If the blasting hole at the blasting point is large, the mounting sleeve 503 can be moved until the clamping plate 502 on its inner wall is inserted into the clamping groove 501 on the surface of the storage cylinder 1. Then, the blasting device is inserted into the blasting hole, and the threaded tube 505 is rotated. While rotating on the surface of the screw 504, the threaded tube 505 moves axially along the screw 504. This causes the clamping arc plate 506 at one end to move to the two clamping arc plates 506 respectively to clamp the inner wall of the blast hole, thereby fixing the blasting device in the blast hole. The controller 3 starts the excitation tube 4 to ignite the exothermic charge. The heat generated instantly causes the gas to generate high pressure. The high pressure gas is discharged through the energy release hole on the expansion tube 6 to impact the surrounding medium and cause the surrounding medium to rupture. During this process, one end of the liquid storage cylinder 1 is restricted and fixed by the positioning component 5 so that the liquid storage cylinder 1 will not be displaced due to the impact force.

[0032] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
