Description

A device for fixing rupture tubes Technical Field

[0001] This utility model relates to the field of blasting tube placement technology, specifically, to a blasting tube fixing device. Background Technology

[0002] Gas blasting tubes are tools used in mining, construction, and other industries where rock or solid materials need to be broken. Compared to traditional explosives, gas blasting technology offers a safer and more controlled option. It typically uses a specific mixture of gases (such as oxygen and fuel gas), which are ignited to create high-pressure gas that breaks up rock or other materials.

[0003] In practical applications, existing methods for deploying gas blasting tubes still have many shortcomings. Currently, the common practice is to manually lift the tube and place it into the pre-drilled blast hole. During this process, a dedicated person must be responsible for supporting the lead wire to prevent it from falling into the hole along with the tube. If the operation is not performed correctly, the lead wire can easily fall into the blast hole, rendering the entire tube unusable, resulting in material waste and reduced operational efficiency.

[0004] Furthermore, although some work sites have attempted to use cranes for mechanized deployment, the complex working environment of mines or construction sites often makes it difficult to position the cranes, limiting their applicability. Even after deployment is completed, the hook still needs to be manually released, and at the moment of release, the blasting pipe may suddenly fall into the blast hole due to loss of support. This process, similar to manual deployment, poses a significant safety hazard and could easily cause accidental injury to nearby workers.

[0005] Therefore, there is an urgent need to provide a device for fixing rupture tubes to solve the above problems. Summary of the Invention

[0006] To address the problems of complex operation, material waste, and safety hazards in the current deployment of gas rupture tubes, especially the risks of accidental wire insertion and sudden drop of the rupture tube during manual lifting and crane deployment, this utility model provides the following technical solution: a rupture tube fixing device, comprising a rupture tube body and a fixing device body for fixing the rupture tube body. The fixing device body includes a support frame, a rotating disk at the bottom of the support frame, a first winding device and a second winding device respectively located at the center of the upper and lower surfaces of the rotating disk, an adjustment component for controlling the sliding of the rope extension end of the second winding device along the radial direction of the rotating disk, a suspension component at the extension end of the adjustment component, a pulley at the edge of the rotating disk opposite to the adjustment component, and a fixing component at the extension end of the second winding device. The rupture tube body is connected to the fixing device body through the suspension component and the fixing component.

[0007] In order to facilitate the movement of the entire support frame to the vicinity of the blast hole, and to make it easier for workers to align the blasting tube body with the blast hole and lower it;

[0008] As a further improvement to this technical solution, the support frame includes several L-shaped support rods arranged in a circumferential pattern, and universal wheels are fixed at the bottom of the support rods; secondly, a mounting frame is rotatably connected to the top of the support frame, and the rotating disk is rotatably connected to the support frame through the mounting frame.

[0009] Based on this, since the traditional method of using a crane requires manual disconnection of the crane from the rupture tube body, accidents can easily occur the moment the rupture tube body detaches from the crane.

[0010] As a further improvement to this technical solution, the suspension assembly slides to the top of the rupture tube body as the rupture tube body gradually turns to a vertical position, automatically releasing the fixing assembly from fixing the top of the rupture tube body.

[0011] As a further improvement to this technical solution, the adjustment component includes a servo motor, a mounting groove is provided in the rotating disk, the servo motor is fixedly connected inside the servo motor, a sliding groove is provided radially in the rotating disk, a threaded screw is rotatably connected in the sliding groove, a driving bevel gear is fixedly provided at the output end of the servo motor, a driven bevel gear is fixedly provided at the end of the threaded screw near the servo motor, and the driving bevel gear and the driven bevel gear mesh with each other; an adjustment ring is slidably connected in the sliding groove, the adjustment ring is threadedly connected to the threaded screw, and the rope extension end of the second winding device passes through the adjustment ring.

[0012] As a further improvement to this technical solution, the suspension assembly includes a suspension rod, the top end of which is fixedly connected to the telescopic end of the rope of the second winding device, and a clamping assembly rotatably connected to the bottom end of the suspension rod. The clamping assembly is detachable and includes two retaining rings whose top ends are rotatably connected to each other. The two retaining rings together form a circular structure adapted to the structure of the rupture tube body. A protrusion is fixedly provided at the bottom of the retaining ring, and the two retaining rings are detachably connected through the two protrusions. Several receiving grooves are evenly opened in the circumference of the retaining ring, and an elastic telescopic rod is fixedly provided in the receiving groove. A clamping wheel is rotatably provided at the telescopic end of the elastic telescopic rod. The retaining ring is tightly fitted to the rupture tube body through several clamping wheels, and the rotation direction of the clamping wheels is along the axial direction of the rupture tube body. A top ring is fixedly provided on the side of the retaining ring opposite to the fixing assembly, and the two top rings form a frustum-shaped structure adapted to the structure of the rupture tube body.

[0013] As a further improvement to this technical solution, the fixing component includes a hook, which is fixedly connected to the telescopic end of the rope of the first winding device. The fixing component also includes a fixing cover, which is connected to the hook. Several locking structures are circumferentially fixed on the outer walls of the fixing cover. The locking structure includes a limiting hook fixed on the fixing cover. A locking body adapted to the limiting hook is fixed on the top end of the rupture tube body opposite to the top ring. The control part of the locking body is arranged opposite to the frustum-shaped structure of the top ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This rupture tube fixing device achieves stable lifting and automatic detachment of both ends of the rupture tube through the coordinated operation of a suspension component and a fixing component. The suspension component adheres to the outer wall of the rupture tube via clamping wheels and can slide on its surface; the fixing component is detachably connected via a locking structure. As the rupture tube gradually becomes vertical, the suspension component moves upward along the tube body and impacts the top ring, triggering the release of the fixing component. This allows for automatic detachment of the rupture tube without manual intervention, effectively preventing safety accidents caused by human error.

[0016] 2. This blasting tube fixing device achieves precise control of the blasting tube tilt angle through the linkage design of the adjustment component and the rotating disk; the servo motor in the adjustment component drives the gear transmission system to rotate the lead screw, thereby controlling the adjustment ring to move radially along the rotating disk, changing the position of the rope of the second winding device, so that the blasting tube can gradually tilt and accurately align with the blasting hole, improving the deployment accuracy and ease of operation, and reducing manual assistance.

[0017] 3. This blasting pipe fixing device enhances the flexibility and positioning capability of the entire device by rotating the rotating disk and the mounting frame, combined with the casters at the bottom of the support frame. The support frame can be quickly moved to the work point and positioned stably, making it easy to align the blasting pipe with the blasting hole, improving work efficiency and reducing labor intensity during handling and positioning.

[0018] 4. This blasting tube fixing device, through the coordinated control of dual winding devices, forms a stable hanging structure, effectively replacing the traditional crane or manual lifting method; the first winding device and the second winding device respectively control the lifting status of the top and middle sections of the blasting tube, and the rope length can be adjusted synchronously during the lowering process to ensure that the blasting tube enters the blasting hole smoothly, fundamentally avoiding the safety hazards caused by the sudden fall of the blasting tube at the moment of unhooking.

[0019] 5. This rupture tube fixing device, by setting the relative arrangement of pulleys and adjusting components, ensures that the fixing components are always at the edge of the rotating disk, maintaining the stability of the force on the top of the rupture tube; thus ensuring that the top of the rupture tube maintains a reasonable distribution of force points during tilting, further enhancing the stability and safety of the overall structure.

[0038] Please refer to Figures 1-4. The purpose of this embodiment is to provide a rupture tube fixing device, including a rupture tube body 11 and a fixing device body for fixing the rupture tube body 11. The fixing device body includes a support frame 1, a rotating disk 4 is provided at the bottom of the support frame 1, a first winding device 5 and a second winding device 6 are respectively provided at the center of the upper and lower surfaces of the rotating disk 4, an adjusting component 9 is provided inside the rotating disk 4 for controlling the rope extension end of the second winding device 6 to slide radially along the rotating disk 4, a suspension component 10 is provided at the extension end of the adjusting component 9, a pulley 7 is provided at the edge of the rotating disk 4 opposite to the adjusting component 9, and a fixing component 8 is provided at the extension end of the second winding device 6. The rupture tube body 11 is connected to the fixing device body through the suspension component 10 and the fixing component 8.

[0039] During operation, the ropes of the first winding device 5 and the second winding device 6 are lowered through the corresponding drive motors on the first winding device 5 and the second winding device 6. Then, the top of the blasting tube body 11 is detachably fixed by the fixing component 8. Then, the suspension component 10 is fixed to the other end of the blasting tube body 11, thus forming a lifting structure for both ends of the blasting tube body 11. Then, the blasting tube body 11 is raised by the corresponding drive motors on the first winding device 5 and the second winding device 6. At this time, the moving end of the adjusting component 9 is located at the edge of the rotating disk 4, that is, the position opposite to the pulley 7. As can be seen from Figure 1, the blasting tube body 11 is in a suspended state.

[0040] Furthermore, referring to Figures 1 and 2, in order to facilitate the movement of the entire support frame 1 to the vicinity of the blast hole and to make it easier for workers to align the blasting tube body 11 with the blast hole and lower it, the support frame 1 includes several L-shaped support rods arranged in a circumferential pattern, and universal wheels 2 are fixed at the bottom of the support rods; secondly, a mounting frame 3 is rotatably connected to the top of the support frame 1, and the rotating disk 4 is rotatably connected to the support frame 1 through the mounting frame 3.

[0041] During operation, the casters 2 facilitate the movement of the entire support frame 1. After moving it to the vicinity of the blast hole, the casters 2 are fixed. Then, the moving end of the adjusting component 9 can be controlled by the adjusting component 9. As shown in Figure 4, when the moving end of the adjusting component 9 moves radially inward along the rotating disk 4, the rope extension end of the second winding device 6 will become longer, and then the blast tube body 11 will tilt. At this time, the worker can align the blast tube body 11 with the blast hole. As the blast tube body 11 continues to penetrate deeper, and in conjunction with the moving end of the adjusting component 9 continuously moves towards the center of the rotating disk 4, the tilt angle of the blast tube body 11 gradually increases. The top of the blast tube body 11, which is the location of the fixing component 8, is always located near the edge of the rotating disk 4 through the cooperation of the fixing component 8 and the pulley 7. As the tilt angle of the blast tube body 11 increases, the rope extension end of the first winding device 5 is controlled to retract, further increasing the tilt angle of the blast tube body 11, making it easier for it to enter the blast hole.

[0042] Specifically, since the traditional method of using a crane requires manual disconnection of the crane from the rupture tube body 11, accidents can easily occur at the moment the rupture tube body 11 detaches from the crane. Therefore, this solution uses a suspension component 10 that slides to the top of the rupture tube body 11 as it gradually turns to a vertical position, automatically releasing the fixing component 8 from the top of the rupture tube body 11. This eliminates the need for manual operation nearby. In other words, as the tilt angle of the rupture tube body 11 increases, and the top of the rupture tube body 11 is always under tension due to the fixing component 8, the suspension component 10 will slide along the rupture tube body 11. When the rupture tube body 11 gradually becomes vertical, the suspension component 10 will slide to the top of the rupture tube body 11, and then use inertia and impact force to break the fixing component 8 from the top of the rupture tube body 11, allowing the fixing component 8 and the suspension component 10 to detach from the rupture tube body 11, achieving complete detachment of the rupture tube body 11.

[0043] Furthermore, referring to Figures 5, 7, and 8, the adjustment assembly 9 includes a servo motor 92, a mounting groove 91 is provided in the rotating disk 4, the servo motor 92 is fixedly connected inside the servo motor 92, a radial groove 96 is provided in the rotating disk 4, a threaded screw 95 is rotatably connected in the groove 96, a drive bevel gear 93 is fixedly provided at the output end of the servo motor 92, a driven bevel gear 94 is fixedly provided at one end of the threaded screw 95 near the servo motor 92, the drive bevel gear 93 and the driven bevel gear 94 mesh with each other; an adjustment ring 97 is slidably connected in the groove 96, the adjustment ring 97 is threadedly connected to the threaded screw 95, and the rope extension end of the second winding device 6 passes through the adjustment ring 97.

[0044] During operation, the servo motor 92 is controlled, and then the bevel gear 93 and the driven bevel gear 94 are driven to rotate the threaded screw 95. Since the adjusting ring 97 is slidably connected in the slide groove 96, the adjusting ring 97 slides back and forth in the slide groove 96. The rope of the second winding device 6 passes through the adjusting ring 97 and then suspends the entire suspension assembly 10. Therefore, as the adjusting ring 97 moves back and forth in the radial direction of the rotating disk 4, the angle between the rope of the second winding device 6 and the blasting tube body 11 changes, thereby causing the blasting tube body 11 to tilt, which makes it easier for the worker to operate the blasting tube body 11 to align the blasting hole.

[0045] Specifically, referring to Figures 5 and 9-11, the suspension assembly 10 includes a suspension rod 101. The top end of the suspension rod 101 is fixedly connected to the rope extension end of the second winding device 6, and the bottom end of the suspension rod 101 is rotatably connected to a clamping assembly. The clamping assembly is detachable and includes two retaining rings 102 whose top ends are rotatably connected to each other. The two retaining rings 102 together form a circular structure adapted to the structure of the rupture tube body 11. A protrusion 107 is fixedly provided at the bottom of the retaining ring 102, and the two retaining rings 102 can be connected by the two protrusions 107. Disassembly and connection: The retaining ring 102 has several circumferentially evenly distributed receiving grooves 104, and an elastic telescopic rod 105 is fixed in the receiving groove 104. The telescopic end of the elastic telescopic rod 105 is rotatably equipped with a clamping wheel 106. The retaining ring 102 is tightly fitted to the rupture tube body 11 through several clamping wheels 106, and the rotation direction of the clamping wheels 106 is along the axial direction of the rupture tube body 11. A top ring 103 is fixed on the side of the retaining ring 102 opposite to the fixing component 8. The two top rings 103 form a frustum-shaped structure that is adapted to the structure of the rupture tube body 11.

[0046] During operation, the opening and closing of the retaining ring 102 is controlled by the protrusion 107 to clamp and fix the rupture tube body 11. After the retaining ring 102 clamps and fixes the rupture tube body 11, the two protrusions 107 are fixed by the nut to close the retaining ring 102. During this process, the rupture tube body 11 will squeeze the clamping wheel 106 on the inner wall of the retaining ring 102. That is, the retaining ring 102 is tightly attached to the rupture tube body 11 through the clamping wheel 106. In this way, when the rupture tube body 11 is tilted, the entire suspension assembly 10 can easily slide along the rupture tube body 11. When the rupture tube body 11 is tilted, the retaining ring 102 slides along the rupture tube body 11 through the clamping wheel 106. When the top ring 103 touches the fixing assembly 8, it triggers the fixing assembly 8 to release the fixation of the rupture tube body 11, thereby realizing the automatic detachment of the entire rupture tube body 11 without the need for personnel to approach and handle the detachment of the rupture tube body 11.

[0047] Further, referring to Figures 5 and 6, the fixing component 8 includes a hook 81, which is fixedly connected to the rope extension end of the first winding device 5. The fixing component 8 also includes a fixing cover 82, which is connected to the hook 81. Several locking structures are circumferentially fixed on the outer wall of the fixing cover 82. The locking structure includes a limiting hook 83 fixed on the fixing cover 82. A locking body 84 adapted to the limiting hook 83 is fixed on the top end of the rupture tube body 11 opposite to the top ring 103. The control part of the locking body 84 is arranged opposite to the frustum-shaped structure of the top ring 103.

[0048] During operation, the top ring 103 has a frustum-shaped structure, which means that from a two-dimensional perspective, the top ring 103 has a wedge-shaped structure. When the top ring 103 slides and impacts the locking body 84, the locking structure composed of the locking body 84 and the limiting hook 83 is existing technology and will not be described in detail. That is, the locking body 84 hooks the limiting hook 83 and then pulls the locking body 84 in the opposite direction to limit the limiting hook 83, thus fixing the fixing cover 82 to the top of the rupture tube body 11. Similarly, when the inclined surface of the top ring 103 impacts the locking body 84, it will push the locking body 84 in the opposite direction, causing the locking body 84 to disengage from the limiting hook 83, so that the entire fixing cover 82 disengages from the rupture tube body 11. Subsequently, the suspension assembly 10 also completely disengages from the rupture tube body 11.

[0049] In summary, this rupture tube fixing device achieves stable lifting, precise positioning, and safe deployment of the rupture tube through the automatic separation mechanism of the suspension component 10 and the fixing component 8, the multi-degree-of-freedom adjustment structure, and the coordinated control of the dual winding device. This effectively solves the problems of complex operation, material waste, and safety hazards in the current gas rupture tube deployment process, especially the risks of accidental wire insertion and sudden drop of the rupture tube during manual lifting and crane deployment.
