Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide blasting technology, and in particular relates to a modular carbon dioxide gas segmented blasting device. Background Technology

[0002] In engineering fields such as mining and tunnel excavation, carbon dioxide gas blasting technology, with its characteristics of low noise, low vibration, high safety, and minimal environmental damage, is gradually becoming an ideal alternative to traditional explosive blasting. However, existing carbon dioxide gas blasting equipment still faces many challenges in practical applications.

[0003] On the one hand, traditional carbon dioxide gas blasting equipment is mostly a one-piece structure, which is bulky and heavy. When transporting it to the blasting site, it lacks flexible and convenient means of movement, requiring large transport equipment and increasing transportation costs and difficulties. After arriving at the site, because the equipment is difficult to move and adjust its position, it is prone to bumps and tilting during the process of moving it to the drilled hole, affecting the normal use and service life of the equipment, and also posing certain safety hazards.

[0004] On the other hand, in the installation phase of blasting equipment, traditional equipment struggles to accurately and slowly deliver blasting components into the holes. Either improper operation leads to misalignment of the blasting components, affecting the blasting effect; or excessive speed during delivery can easily cause equipment damage or safety accidents.

[0005] To address these issues, we provide a modular carbon dioxide gas segmented blasting device. Utility Model Content

[0006] The purpose of this invention is to provide a modular carbon dioxide gas segmented blasting device. Through the cooperation of the displacement component and the clamping and pushing component, it solves the problems of the lack of flexible and convenient movement method and the difficulty in accurately and slowly transporting the blasting component into the hole in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a modular carbon dioxide gas segmented blasting device, comprising a displacement assembly. A clamping and pushing assembly is movably connected to the top of the displacement assembly, and the inner cavity of the clamping and pushing assembly holds a blasting assembly. The displacement assembly includes a frame, with a placement plate movably connected to one side of the top of the frame via a pin, and a hydraulic telescopic rod movably connected to the other side of the top of the frame via a pin. The other end of the hydraulic telescopic rod is movably connected to the bottom of the placement plate via a pin. Universal wheels are fixedly connected to the four corners of the bottom of the frame. The clamping and pushing assembly includes moving slots at the front and rear ends of the top of the placement plate. A lead screw is fixedly connected to the inner cavity of the moving slot via a bearing. The end of the lead screw away from the bearing extends through to the outside of the placement plate and is fixedly connected to a driven bevel gear. A driving bevel gear meshes with the surface of the driven bevel gear. A dual-output shaft motor is fixedly connected between the two driving bevel gears, with one side of the dual-output shaft motor fixedly connected to the placement plate. A clamping and positioning structure is movably connected to the top of the lead screw.

[0009] The present invention is further configured such that the blasting assembly includes a receiving tube, one end of which is provided with a pressure relief plate, and a blasting tube is threadedly connected to the inner cavity of the receiving tube on one side of the pressure relief plate. A pressure relief hole is formed on the surface of the blasting tube. A safety membrane is provided on the other side of the inner cavity of the receiving tube. A high thermal conductivity rod is provided on the inner cavity of the receiving tube on one side of the safety membrane. A fastening cap is threadedly connected to the surface of the receiving tube. The space between the safety membrane and the pressure relief plate in the inner cavity of the receiving tube is filled with liquid carbon dioxide. Through the cooperation of the receiving tube, pressure relief plate, and blasting tube components, precise pressure relief and blasting are achieved after the liquid carbon dioxide is heated, vaporized, and expanded. The high thermal conductivity rod can quickly conduct heat to trigger the blast, ensuring both blasting effect and safety.

[0010] The present invention is further configured such that handles are fixedly connected to both the front and rear ends of one side of the frame, and a controller is fixedly connected to the surface of the handle. The handle makes it convenient for the operator to push the equipment, and the controller on the surface integrates the equipment operation function, so that the operator can control the equipment action at any time during the movement of the equipment, thereby improving the ease of operation.

[0011] The present invention is further configured such that through holes for lead screw are provided at both the front and rear ends of one side of the placement plate, and the through holes and lead screw are fixedly connected by bearings. The connection between the through holes and lead screw ensures that lead screw is relatively stable with respect to the placement plate during rotation, reduces shaking, and makes the movement of the clamping and positioning structure more precise.

[0012] The present invention is further configured such that the clamping and positioning structure includes a fixed mounting bracket fixedly connected to the front and rear ends of one side of the top of the placement plate and a movable mounting bracket threadedly connected to a lead screw. The inner cavities of the fixed mounting bracket and the movable mounting bracket are threadedly connected to a lead screw and a limit rod is slidably connected. One end of the lead screw is fixedly connected to a clamping plate through a bearing. The surface of the clamping plate is fixedly connected to one end of the limit rod. The fixed mounting bracket and the movable mounting bracket cooperate, and the lead screw and the limit rod work together. The clamping plate can be moved by adjusting the lead screw to achieve firm clamping and precise positioning of the explosive component.

[0013] The present invention is further configured such that a turntable is fixedly connected to the end of the lead screw two away from the clamping plate, and the surface of the turntable is provided with anti-slip texture. The turntable and the anti-slip texture on the surface of the lead screw two end make it easy for the operator to manually adjust the lead screw two, providing a better grip and operating force, and facilitating fine adjustment of the position of the clamping plate.

[0014] The present invention is further provided that a rubber pad is fixedly connected to the side of the clamping plate that contacts the blasting component. The clamping plate adopts an arc-shaped design. The arc-shaped design of the clamping plate and the rubber pad can closely fit the surface of the blasting component, increase the friction to prevent slippage, and at the same time avoid damage to the blasting component during the clamping process.

[0015] The present invention is further configured such that the bottom of the movable mounting frame is provided with a threaded hole for use with a lead screw, and the inner cavity of the movable mounting frame is provided with a threaded hole for use with a lead screw. The threaded hole on the movable mounting frame cooperates with the lead screw to achieve horizontal movement, and the threaded hole on the movable mounting frame cooperates with the lead screw to achieve adjustment of the position of the clamping plate, ensuring that the structure is tightly connected and the function is stable.

[0016] The present invention has the following beneficial effects.

[0017] 1. The frame in the displacement component of this utility model serves as the load-bearing foundation, and the casters give the equipment flexible steering and movement capabilities. Compared with traditional large equipment, it does not require special transportation tools and can move freely on the construction site, significantly reducing transportation costs. Through the extension and retraction adjustment of the hydraulic telescopic rod, the angle of the placement plate can be easily changed. During transportation, the explosive component is kept horizontally supported. When it reaches the hole, the placement plate can be erected so that the explosive component is naturally and vertically aligned with the hole, effectively avoiding bumps and tilting problems during the handling process. While ensuring the safety of the equipment, it also improves transportation efficiency and flexibility.

[0018] 2. The dual-output shaft motor of this utility model drives the active bevel gear to rotate, which in turn drives the driven bevel gear and lead screw to rotate, thereby enabling the movable mounting frame to move along lead screw. This allows for precise adjustment of the position of the blasting component. By rotating the turntable to adjust lead screw, the clamping plate can be made to fit tightly against the blasting component. The arc design and rubber pads ensure stable clamping without damaging the equipment. During the process of pushing the blasting component into the hole, the moving speed can be precisely controlled to avoid equipment damage or positional deviation caused by excessive speed. This achieves precise and slow installation, effectively improving the blasting effect and operational safety, and solving many problems in the installation process of traditional equipment.

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1-5 This utility model is a modular carbon dioxide gas segmented blasting device, including a displacement component 1. A clamping and pushing component 2 is movably connected to the top of the displacement component 1. A blasting component 3 is clamped within the inner cavity of the clamping and pushing component 2. The displacement component 1 includes a frame 11. A placement plate 12 is movably connected to one side of the top of the frame 11 via a pin. A hydraulic telescopic rod 13 is movably connected to the other side of the top of the frame 11 via a pin. The other end of the hydraulic telescopic rod 13 is movably connected to the bottom of the placement plate 12 via a pin. Universal wheels 14 are fixedly connected to the four corners of the bottom of the frame 11. The clamping and pushing assembly 2 includes a movable groove 21 opened at the front and rear ends of the top of the placement plate 12. The inner cavity of the movable groove 21 is fixedly connected to a lead screw 22 via a bearing. The end of the lead screw 22 away from the bearing extends through to the outside of the placement plate 12 and is fixedly connected to a driven bevel gear 23. The surface of the driven bevel gear 23 meshes with a driving bevel gear 24. A dual output shaft motor 25 is fixedly connected between the two driving bevel gears 24. One side of the dual output shaft motor 25 is fixedly connected to the placement plate 12. The top of the lead screw 22 is movably connected to a clamping and positioning structure 26.

[0029] Specifically: The frame 11 serves as a stable main frame, with one side of its top connected to the placement plate 12 via a pin. This hinged connection allows the placement plate 12 to rotate flexibly around the pin. The other side is connected to the hydraulic telescopic rod 13 via a pin. The extension and retraction of the hydraulic telescopic rod 13 can precisely control the tilt angle of the placement plate 12. When it is necessary to transport the blasting component 3, the hydraulic telescopic rod 13 retracts, and the placement plate 12 remains horizontal, providing a stable bearing surface for the blasting component 3. After reaching the blasting operation point, the hydraulic telescopic rod 13 extends, pushing the placement plate 12 upright, making it easier to transport the blasting component 3 to the hole. The universal wheels 14 at the four corners of the bottom of the frame 11 are made of high-strength wear-resistant material and have a 360-degree free rotation function, allowing the equipment to easily turn and move in complex construction sites. The clamping and pushing component 2 is installed on the top of the placement plate 12, undertaking the task of precise positioning and pushing of the blasting component 3.

[0030] Example 2

[0031] Please see Figure 1-5Based on Embodiment 1, the blasting assembly 3 includes a receiving tube 31, with a pressure relief plate 32 at one end of the receiving tube 31. A blasting tube 33 is threadedly connected to the inner cavity of the receiving tube 31 on one side of the pressure relief plate 32. A pressure relief hole 34 is opened on the surface of the blasting tube 33. A safety membrane 35 is provided on the other side of the inner cavity of the receiving tube 31. A high thermal conductivity rod 36 is provided on the inner cavity of the receiving tube 31 on one side of the safety membrane 35. A fastening cap 37 is threadedly connected to the surface of the receiving tube 31. The space between the safety membrane 35 and the pressure relief plate 32 in the inner cavity of the receiving tube 31 is filled with liquid carbon dioxide. Handles 15 are fixedly connected to both the front and rear ends of one side of the frame 11. A controller is fixedly connected to the surface of the handle 15. Through holes for lead screw 22 are opened at both the front and rear ends of one side of the placement plate 12. The through holes and lead screw 22 are fixedly connected by bearings. Clamping and positioning structure The structure 26 includes a fixed mounting bracket 261 fixedly connected to the front and rear ends of one side of the top of the placement plate 12, and a movable mounting bracket 262 threadedly connected to the lead screw 22. The inner cavities of the fixed mounting bracket 261 and the movable mounting bracket 262 are threadedly connected to the lead screw 263 and the limiting rod 264 is slidably connected. One end of the lead screw 263 is fixedly connected to the clamping plate 265 through a bearing. The surface of the clamping plate 265 is fixedly connected to one end of the limiting rod 264. The end of the lead screw 263 away from the clamping plate 265 is fixedly connected to a turntable. The surface of the turntable is provided with anti-slip texture. The side of the clamping plate 265 that contacts the explosive component 3 is fixedly connected to a rubber pad. The clamping plate 265 adopts an arc-shaped design. The bottom of the movable mounting bracket 262 is provided with a threaded hole 1 for use with the lead screw 22, and the inner cavity of the movable mounting bracket 262 is provided with a threaded hole 2 for use with the lead screw 263.

[0032] Specifically: Through the cooperation of the receiving tube 31, pressure relief plate 32, and rupture tube 33, precise pressure relief and rupture are achieved after the liquid carbon dioxide is heated, vaporized, and expanded. The high thermal conductivity rod 36 can quickly conduct heat to trigger the rupture, ensuring the rupture effect and safety. The handle 15 facilitates the operator to push the equipment. The controller on the surface integrates the equipment operation functions, allowing the operator to control the equipment's actions at any time during the movement of the equipment, improving the ease of operation. The through hole and the lead screw 22 are connected by a bearing to ensure that the lead screw 22 is relatively stable with the placement plate 12 during rotation, reducing shaking and making the clamping and positioning structure 26 move more accurately. The fixed mounting bracket 261 cooperates with the movable mounting bracket 262, and the lead screw 263 and the limit rod 264 work together. The clamping plate 265 can be moved by adjusting the lead screw 263 to achieve a firm grip and precise positioning of the explosive component 3. The turntable and anti-slip texture on the end of the lead screw 263 make it easy for the operator to manually adjust the lead screw 263, providing a better grip and operating force, and facilitating fine adjustment of the position of the clamping plate 265. The arc design and rubber pad of the clamping plate 265 can fit tightly against the surface of the explosive component 3, increasing friction to prevent slippage, and avoiding damage to the explosive component 3 during clamping. The threaded hole 1 on the movable mounting bracket 262 cooperates with the lead screw 22 to achieve horizontal movement, and the threaded hole 2 cooperates with the lead screw 263 to achieve position adjustment of the clamping plate 265, ensuring a tight structural connection and stable function.

[0033] The working principle of this utility model is as follows: The blasting component 3 is placed on the clamping and pushing component 2. By rotating the turntable, the lead screw 263 can be rotated. The lead screw 263 drives the clamping plate 265 to move and clamp and fix the blasting component 3. Then, the equipment is moved to the vicinity of the blasting operation point by the universal wheels 14 at the bottom of the displacement component 1. The operator can hold the handle 15 on the frame 11 and start the hydraulic telescopic rod 13 through the controller on the surface to make the placement plate 12 stand up. At this time, the clamping plate 265 on the surface of the fixed mounting bracket 261 is released from the fixed state. Then, the dual-output shaft motor 25 starts, driving the active bevel gear 24, the driven bevel gear 23 and the lead screw 22 to rotate, causing the movable mounting frame 262 to move along the lead screw 22, slowly pushing the blasting component 3 into the drilled hole. Then, the clamping plate 265 on the movable mounting frame 262 is released from its locked state. During the blast, the high thermal conductivity rod 36 conducts heat to cause the liquid carbon dioxide in the containment tube 31 to vaporize and expand. After reaching a certain pressure, it breaks through the pressure relief plate 32 and achieves segmented blasting through the pressure relief hole 34 of the blasting tube 33, thus completing the blasting operation.
