Description

Technical Field

[0001] This utility model relates to a gas separator, and more particularly to a pull-up gas separator quick-release device. Background Technology

[0002] A gas spacer is a device used in engineering blasting. Its main function is to optimize blasting effects and reduce blast hazards by forming a gas spacer layer in the borehole. A gas spacer (usually filled with air or inert gas) is placed between the explosive and the packing material in the borehole to form a flexible buffer layer. When the high-pressure gas generated by the explosion passes through the gas spacer layer, its energy is gradually absorbed and diffused, preventing energy concentration at the borehole opening or surface rock. This allows the energy to be applied more evenly to the rock mass along the entire length of the borehole, improving rock-breaking efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a quick venting device for a pull-up gas separator.

[0004] Therefore, this utility model provides a quick-release device for a pull-up gas separator, including an inflation mechanism. The inflation mechanism includes an inflation shell, and an activation mechanism is installed on the inner wall of the inflation shell. The activation mechanism includes a first fixing ring, the surface of which is fixedly connected to the inner wall of the inflation shell. A push rod is movably connected inside the first fixing ring, and a connecting shaft is fixedly connected to the surface of the push rod. A limiting mechanism is installed on the upper surface of the first fixing ring, and the limiting mechanism includes a spring. One end of the spring is fixedly connected to the upper surface of the first fixing ring, and the other end of the spring is fixedly connected to a second fixing ring. A gas cylinder is fixedly connected to the inner wall of the second fixing ring, and a cap is installed on the upper surface of the gas cylinder. A fixing mechanism is installed on the surface of the gas cylinder, and the fixing mechanism includes a connecting plate. A first rotating shaft is movably connected to the surface of the connecting plate, a first torsion spring is installed on the surface of the first rotating shaft, and a rotating rod is movably connected to the surface of the first rotating shaft. The connecting shaft is installed inside the rotating rod.

[0005] Preferably, the upper surface of the first fixing ring is provided with a third groove, and the inner wall of the third groove is movably connected to a slider, the upper surface of the slider being fixedly connected to the surface of the push rod.

[0006] Preferably, the surface of the rotating rod is provided with a second through hole, the inner wall of the second through hole is in contact with the surface of the connecting shaft, and the surface of the rotating rod is in contact with the surface of the bottle cap.

[0007] Preferably, a limiting block is fixedly connected to the inner wall of the inflatable shell, and a first through hole is provided on the surface of the second fixing ring. A locking pin is installed on the inner wall of the first through hole, and the end of the locking pin extends into the interior of the limiting block.

[0008] Preferably, a pull rope is fixedly connected to the upper surface of the inflatable shell, and a base is fixedly connected to the lower surface of the inflatable shell. A first groove is formed on the lower surface of the base, and a second groove is formed inside the first groove.

[0009] Preferably, a storage mechanism is installed inside the second groove. The storage mechanism includes a movable block, which is movably connected to the inner wall of the second groove. A second rotating shaft is fixedly connected to the surface of the movable block, a second torsion spring is installed on the surface of the second rotating shaft, and a locking block is fixedly connected to the surface of the movable block.

[0010] Preferably, a rotating plate is movably connected to the surface of the second rotating shaft, and a baffle is fixedly connected to the inner wall of the first groove, with the upper surface of the baffle in contact with the lower surface of the rotating plate.

[0011] This utility model provides a rapid venting device for a pull-up gas separator, which has the following beneficial effects:

[0012] (1) In use, after pulling the rope to insert the gas spacer into the blast hole to the predetermined depth, lift the spacer slightly above the hole opening and then quickly lower it. Due to inertia, the gas cylinder will move towards the base. At this time, the position of the first fixing ring remains unchanged. The push rod installed on the first fixing ring will push the end of the rotating rod that contacts the bottle cap upwards and rotate around the first rotating shaft. After overcoming the elastic force of the first torsion spring, the gas inside the gas cylinder will push the bottle cap off, quickly releasing a large amount of gas. Compared with conventional devices, which require opening the gas cylinder first and then inserting the gas spacer into the hole to be blasted, and which prevent the gas cylinder from releasing all the gas before reaching the predetermined position, causing the gas spacer to get stuck at a distance from the explosive, the gas release speed is slow after opening the gas cylinder, reducing work efficiency, this device can remove the bottle cap on the gas cylinder after reaching the designated position, allowing for rapid gas release and improving work efficiency.

[0013] (2) In use, press the rotating plate in the first groove to make it rotate inwards to easily wind and store the pull rope. When you need to quickly remove the pull rope, just push the rotating plate a short distance inwards to the second groove. At this time, the rotation of the rotating plate is no longer restricted by the baffle, and the pull rope wound in the first groove can be quickly removed. Attached Figure Description

[0022] Example 1:

[0023] Depend on Figures 1-5As shown, this utility model provides a quick-release device for a pull-up gas separator, including an inflation mechanism 1. The inflation mechanism 1 includes an inflation shell 101, and an activation mechanism 2 is installed on the inner wall of the inflation shell 101. The activation mechanism 2 includes a first fixing ring 201, the surface of which is fixedly connected to the inner wall of the inflation shell 101. A push rod 204 is movably connected inside the first fixing ring 201, and a connecting shaft 205 is fixedly connected to the surface of the push rod 204. A limiting mechanism 3 is installed on the upper surface of the first fixing ring 201, and the limiting mechanism 3 includes a spring 306. One end of the spring 306 is fixedly connected to the upper surface of the first fixing ring 201, and the other end of the spring 306 is fixedly connected to a second fixing ring 305. A gas cylinder 301 is fixedly connected to the inner wall of the second fixing ring 305. A bottle cap 307 is installed on the upper surface of the gas cylinder 301, and a fixing mechanism is installed on the surface of the gas cylinder 301. Structure 4, the fixing mechanism 4 includes a connecting plate 401, a first rotating shaft 402 is movably connected to the surface of the connecting plate 401, a first torsion spring 403 is mounted on the surface of the first rotating shaft 402, a rotating rod 404 is movably connected to the surface of the first rotating shaft 402, and a connecting shaft 205 is installed inside the rotating rod 404. After pulling the pull rope 102 to insert the gas spacer into the rupture hole to a predetermined depth, the spacer is first lifted above the hole opening and then quickly lowered. Due to inertia, the gas cylinder 301 will move towards the base 103, while the position of the first fixing ring 201 remains unchanged. The push rod 204 installed on the first fixing ring 201 will push the end of the rotating rod 404 that is in contact with the bottle cap 307 upwards, while rotating around the first rotating shaft 402. After overcoming the elastic force of the first torsion spring 403, the gas inside the gas cylinder 301 will push the bottle cap 307 off, quickly releasing a large amount of gas.

[0024] Example 2:

[0025] Depend on Figures 4-6As shown, this utility model provides a pull-up gas separator quick-release device. A third groove 202 is formed on the upper surface of the first fixing ring 201. A slider 203 is movably connected to the inner wall of the third groove 202. The upper surface of the slider 203 is fixedly connected to the surface of the top rod 204. A second through hole 405 is formed on the surface of the rotating rod 404. The inner wall of the second through hole 405 is in contact with the surface of the connecting shaft 205. The surface of the rotating rod 404 is in contact with the surface of the bottle cap 307. A limit block 302 is fixedly connected to the inner wall of the inflation shell 101. The second fixing ring... A first through hole 303 is formed on the surface of the 305. A locking pin 304 is installed on the inner wall of the first through hole 303. The end of the locking pin 304 extends into the interior of the limiting block 302. First, the locking pin 304 on the second fixing ring 305 is pinched through the inflation shell 101, causing the locking pin 304 to fall off and the limiting block 302 to be separated from the second fixing ring 305. Then, the pull rope 102 is carefully pulled to insert the gas spacer into the rupture hole to the predetermined depth. The pull rope 102 is fixedly connected to the upper surface of the inflation shell 101, and the base 103 is fixedly connected to the lower surface of the inflation shell 101. A first groove 104 is formed on the lower surface of the base 103. A second groove 105 is formed inside the first groove 104. A storage mechanism 5 is installed inside the second groove 105. The storage mechanism 5 includes a moving block 501, which is movably connected to the inner wall of the second groove 105. A second rotating shaft 503 is fixedly connected to the surface of the moving block 501. A second torsion spring 505 is mounted on the surface of the second rotating shaft 503. A locking block 502 is fixedly connected to the surface of the moving block 501. A rotating plate 504 is movably connected to the surface of the second rotating shaft 503. A baffle 506 is fixedly connected to the inner wall of 104. The upper surface of the baffle 506 is in contact with the lower surface of the rotating plate 504. By pressing the rotating plate 504 in the first groove 104 and making it rotate inward, the pull rope 102 can be easily wound and stored. When it is necessary to quickly remove the pull rope 102, simply push the rotating plate 504 a short distance inward into the second groove 105. At this time, the rotation of the rotating plate 504 is no longer restricted by the baffle 506, and the pull rope 102 wound in the first groove 104 can be quickly removed.

[0026] Working principle: First, pinch the locking pin 304 on the second fixing ring 305 through the inflation shell 101, causing the locking pin 304 to disengage and separating the limiting block 302 from the second fixing ring 305. Then, carefully pull the pull rope 102 to insert the gas spacer into the rupture hole to the predetermined depth. After the spacer reaches the predetermined depth, lift it slightly above the hole and then quickly lower it. Due to inertia, the gas cylinder 301 will move towards the base 103. At this time, the position of the first fixing ring 201 remains unchanged. The push rod 204 installed on the first fixing ring 201 will push the end of the rotating rod 404 that is in contact with the bottle cap 307 upwards, while simultaneously rotating around... As the first rotating shaft 402 rotates, overcoming the elastic force of the first torsion spring 403, the gas inside the gas cylinder 301 will push the cap 307 off, quickly releasing a large amount of gas. Pressing the rotating plate 504 in the first groove 104 will cause it to rotate inward, making it easy to wind and store the pull rope 102. When it is necessary to quickly remove the pull rope 102, simply push the rotating plate 504 a short distance inward into the second groove 105. At this time, the rotation of the rotating plate 504 is no longer restricted by the baffle 506, and the pull rope 102 wound inside the first groove 104 can be quickly removed.
