Description

Technical Field

[0001] This utility model relates to the field of blasting engineering technology, and in particular to a blasting tube fixing device. Background Technology

[0002] Blasting engineering refers to a construction method that uses explosives to excavate earth and rock, and to demolish or destroy foundations, buildings, and structures. There are many types of explosives, and the most commonly used explosives in construction engineering include ammonium nitrate explosives, nitroglycerin explosives, and black powder.

[0003] For example, Chinese utility model patent (CN216859499U) discloses a blasting tube fixing device for blasting engineering, which describes: "By rotating the screw, the push plate at the bottom of the screw moves. At the same time as the push plate moves, the pressure plate below the push plate moves synchronously with the push plate. When the clamping block on the bottom surface of the pressure plate abuts against the blasting tube in the fixing seat, the blasting tube in the fixing seat can be limited and fixed, preventing the blasting tube from loosening or shifting in the fixing seat, thus improving the stability of the blasting tube in the fixing seat. The use of anti-slip blocks on the clamping blocks can effectively increase the friction between the clamping blocks and the blasting tube." This further improves the stability of the blasting tube in the fixing seat, which is beneficial to improving its performance. It also records that: "Existing blasting tube fixing devices for blasting projects have certain limitations in use. For example, existing blasting tube fixing devices for blasting projects have problems with the fixing effect of the blasting tube being unsatisfactory. The blasting tube is prone to loosening and falling off, which greatly reduces its performance. In addition, existing blasting tube fixing devices for blasting projects also have problems with the buffering and shock absorption effect being unsatisfactory. When the device is subjected to external blasting force, it is easy to damage the device, which can easily affect the service life of the device."

[0004] In summary, the following technical problems exist in the prior art: when fixing a long rupture tube, the rupture tube fixing device in the above-mentioned patent is difficult to fix stably, requiring multiple devices to be set up simultaneously for clamping. Moreover, when installing and removing a long rupture tube, it is necessary to insert or pull it horizontally, which is laborious and troublesome. Therefore, this application proposes a rupture tube fixing device to solve the technical problems mentioned in the above-mentioned patent and provide a new technical solution. Utility Model Content

[0028] As described in the background art, when fixing a long bursting tube, the aforementioned patent's bursting tube fixing device is difficult to fix stably, requiring multiple devices to be set up simultaneously for clamping. Furthermore, when installing and removing a long bursting tube, it is necessary to insert or pull it horizontally, which is quite laborious and troublesome.

[0029] To solve this technical problem, this utility model provides a blasting tube fixing device, which is applied to blasting engineering.

[0030] For details, please refer to Figures 1-6 The rupture tube fixing device specifically includes:

[0031] Mounting base 1, fixing mechanism 2 and supporting mechanism 3. The mounting base 1 is provided with a fixing mechanism 2 for fixing the rupture tube on the upper part, and the mounting base 1 is provided with supporting mechanisms 3 at both lower ends for supporting and fixing the device as a whole.

[0032] The fixing mechanism 2 includes a moving bar 4, a first slide groove 5, a sliding block 6, a clamping assembly, a guiding assembly, and a driving assembly. Two moving bars 4 are symmetrically arranged at both ends of the upper part of the mounting base 1. A sliding block 6 is fixedly connected to the lower middle part of each of the two moving bars 4. Two first slide grooves 5 are symmetrically opened on the surface of the mounting base 1 at positions corresponding to the sliding blocks 6. The two sliding blocks 6 are slidably connected to the two first slide grooves 5 respectively.

[0033] The rupture tube fixing device provided by this utility model, through the structural design of the fixing mechanism 2, allows the knob 16 to be rotated to drive the clamping block 12 to clamp the two sides of the rupture tube simultaneously at multiple points, thereby improving the stability of the rupture tube. Furthermore, the height of the sleeve rod 11 and the clamping block 12 can be adjusted according to the height of the rupture tube, effectively improving the working efficiency and practicality of the device.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figures 1-4 A rupture tube fixing device includes: a mounting base 1, a fixing mechanism 2 and a support mechanism 3. The mounting base 1 is provided with a fixing mechanism 2 for fixing the rupture tube above it, and the mounting base 1 is provided with support mechanisms 3 at both ends below it for supporting and fixing the device as a whole.

[0037] Specifically, the fixing mechanism 2 includes a moving bar 4, a first slide groove 5, a sliding block 6, a clamping assembly, a guiding assembly, and a driving assembly. Two moving bars 4 are symmetrically arranged at both ends of the upper part of the mounting base 1. A sliding block 6 is fixedly connected to the lower middle part of each of the two moving bars 4. Two first slide grooves 5 are symmetrically opened on the surface of the mounting base 1 at positions corresponding to the sliding blocks 6. The two sliding blocks 6 are slidably connected to the two first slide grooves 5 respectively.

[0038] Furthermore, the clamping assembly includes a second sliding groove 9, a moving rod 10, a sleeve rod 11, a clamping block 12, a positioning hole 13, and a hand-tightening bolt 14. The surface of the moving bar 4 is provided with the second sliding groove 9. Two moving rods 10 are symmetrically arranged above the moving bar 4. The two moving rods 10 are slidably connected to the second sliding groove 9. A sleeve rod 11 is sleeved on the outer side of each of the two moving rods 10. The sleeve rod 11 is slidably connected to the moving rod 10. A clamping block 12 is fixedly connected to the side of the two sleeve rods 11 that is close to each other. A hand-tightening bolt 14 is threadedly connected to the outer side of the sleeve rod 11. Multiple positioning holes 13 are vertically provided on the surface of the moving rod 10 and at the position corresponding to the hand-tightening bolt 14. The hand-tightening bolt 14 extends into the interior of the positioning hole 13.

[0039] It is known that during use, the hand-tightening bolt 14 can be rotated to disengage it from the inside of the positioning hole 13, thereby releasing the sliding limit of the sleeve rod 11. The height position of the sleeve rod 11 and the clamping block 12 can be adjusted according to the height of the rupture tube. Then, the height position can be adjusted by rotating the hand-tightening bolt 14 back.

[0040] Furthermore, the guide assembly includes an X-connector 7 and a fixed base 8. The X-connector 7 is rotatably connected to the upper center of the mounting base 1, and the fixed base 8 is fixedly connected to the outer side of each moving rod 10. The ends of the X-connector 7 are rotatably connected to the fixed base 8.

[0041] Furthermore, the drive assembly includes a threaded rod 15 and a knob 16. Two threaded rods 15 are rotatably connected to the inner sides of the two first slide grooves 5 respectively. The threads of the two threaded rods 15 rotate in opposite directions. Two sliding blocks 6 are threadedly connected to the surfaces of the two threaded rods 15 respectively. The ends of the two threaded rods 15 that are close to each other are fixedly connected. A knob 16 is rotatably connected to the end of the mounting base 1 at a position corresponding to the threaded rods 15. The knob 16 is fixedly connected to the threaded rods 15.

[0042] It can be seen that during use, the rupture tube can be placed between the clamping blocks 12, and then the knob 16 can be rotated to drive the two threaded rods 15 to rotate. Because the two threaded rods 15 rotate in opposite directions, the two sliding blocks 6 and the moving bar 4, which are threadedly connected to the threaded rods 15, gradually move closer or further away along the direction of the first slide groove 5. During the movement of the moving bar 4, the X-connecting frame 7 in the middle of the mounting base 1 will also drive the moving rod 10 and the sleeve rod 11 to move closer and further away along the direction of the second slide groove 9 through the fixed base 8, so that the clamping block 12 fixed to the sleeve rod 11 is in contact with or away from the two sides of the rupture tube, which effectively improves the working efficiency and practicality of the device.

[0043] Example 2:

[0044] The rupture tube fixing device provided in Example 1 is further optimized, specifically, as follows: Figures 5-6 As shown, the support mechanism 3 further includes a base 17, a fixed frame 18, a reinforcing rib 19, a ground anchor 21, a connecting block 22, and a shock-absorbing component. The base 17 is provided at the lower end of the mounting seat 1. The fixed frame 18 is fixedly connected to the middle of the base 17. The reinforcing ribs 19 are fixedly connected to both sides of the fixed frame 18. The ground anchor 21 is movably connected to the end of the base 17. The connecting block 22 is fixedly connected to the lower end of the mounting seat 1. The connecting block 22 extends into the interior of the fixed frame 18.

[0045] Furthermore, the shock-absorbing component includes a positioning groove 20, a protruding post 23, and a shock-absorbing spring 24. The surface of the fixed frame 18 is provided with a positioning groove 20, and the inner side of the positioning groove 20 is slidably connected to the protruding post 23. The protruding post 23 is fixedly connected to the connecting block 22. The shock-absorbing spring 24 is provided below the connecting block 22, and the upper and lower ends of the shock-absorbing spring 24 are fixedly connected to the connecting block 22 and the base 17, respectively.

[0046] It is known that during use, the base 17 can be fixed to the ground by inserting the ground anchor 21 into the ground. When the device is subjected to impact, it will drive the connecting block 22 and the protruding post 23 to move along the positioning groove 20. Then, the shock-absorbing spring 24 under the connecting block 22 will buffer the impact and prevent the device from being damaged.
