Description

Technical Field

[0001] The utility model relates to the field of blasting engineering, in particular to an axial decoupling independent charging device. Background Technique

[0002] The axial decoupling charge structure is a blasting technique that involves loading discontinuous explosives axially in a blast hole, with these explosives separated by non-explosive media (such as air, water, foam, etc.). In civil engineering such as tunnel excavation, mine exploitation, and urban demolition, the axial discontinuous charge structure can help achieve more precise blasting, reduce damage to the surrounding rock mass, and lower maintenance costs. This charging method can generate discontinuous blast waves during blasting, thereby controlling the spatio-temporal distribution of the release of explosive energy to a certain extent to achieve a specific blasting effect; by adjusting the interval between explosives and the charge amount, the propagation and energy release of the blast wave can also be controlled, reducing excessive damage to the surrounding rock mass, improving blasting efficiency and safety; and it can also reduce the vibration and noise generated by blasting to a certain extent, reducing the negative impact on the surrounding environment and buildings.

[0003] Currently, there are many methods and devices for axial decoupling charging. For example, in Chinese Patent Publication No. CN118129555A, it is proposed to use a fixing component to fixedly install a medicine tube inside a blast hole, and then control a charging vehicle to install mixed explosives inside the medicine tube in a discontinuous charging manner, so as to achieve axial uniform decoupling charging. Another example is that Chinese Patent Publication No. CN112696999A proposes to use multiple charging tubes, multiple tamping tubes, as well as a pulling rope, a rope clip, and a plug to achieve axial decoupling charging. Although the above patents have well achieved axial decoupling charging, the designed technologies are complex, there are many instruments and equipment, or multiple devices need to be operated together, the operation is not flexible, the production is inconvenient, and the applicable surface of the decoupling medium material types is relatively narrow. Therefore, an axial decoupling independent charging device is proposed to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: an axially uncoupled independent charge device includes a charge barrel 1 for accommodating an explosive 2 and a medium material and a support plate 5 for supporting the explosive 2. The charge barrel 1 is arranged in the shape of a hollow thin-walled cylinder. An explosive 2 for achieving a blasting effect is arranged at the top end of the support plate 5. A detonating fuse 3 for guiding the explosion of the explosive 2 penetrates and is installed at the top end of the explosive 2. A positioning component 4 for fixing the installation positions of the explosive 2 and the medium material is arranged on the inner wall of the charge barrel 1. The positioning component 4 includes a protrusion 41 for supporting the first support leg 44 and the second support leg 45. The top end of the protrusion 41 is set as a plane, and the bottom end is provided with an inclined surface. The protrusion 41 is arranged on the inner wall of the charge barrel 1, and a groove 42 for accommodating the first support leg 44 and the second support leg 45 is arranged at the bottom end of the protrusion 41.

[0031] Refer to Figure 3 - Figure 5, the positioning assembly 4 further includes a sliding plate 43 for adjusting the installation position. The sliding plate 43 slides on the inner wall of the charge barrel 1. The front end of the sliding plate 43 is fixedly connected with a supporting plate 48 for supporting the support plate 5. The support plate 5 is placed on the top of the supporting plate 48. The front end of the sliding plate 43 is fixedly connected with a rotating shaft 46 for supporting the rotation of the first support leg 44 and the second support leg 45. The outer wall of the rotating shaft 46 is rotatably connected with the first support leg 44 for fixing the front end of the sliding plate 43. The outer wall of the rotating shaft 46 is rotatably connected with the second support leg 45 for supporting the rear end of the sliding plate 43 near the front end of the first support leg 44. The first support leg 44 and the second support leg 45 are arranged in an X-shaped cross. The bottoms of the first support leg 44 and the second support leg 45 are both set as planes. The top end of the second support leg 45 is fixedly connected with a support spring 47 for pushing the first support leg 44 and the second support leg 45 outwards. The right end of the support spring 47 is fixedly connected to the top end of the first support leg 44. The support spring 47 will always push the first support leg 44 and the second support leg 45 outwards to keep them in an X shape.

[0032] Refer to Figure 3 - Figure 5 , the first support leg 44 is adapted to the convex block 41, and the second support leg 45 is adapted to the convex block 41. When the sliding plate 43 moves upwards, the convex block 41 will squeeze the first support leg 44 and the second support leg 45 with the inclined plane, so that they can be forced to rotate inwards. When the first support leg 44 and the second support leg 45 reach the ground groove 42, the support spring 47 will extend outwards and force them to snap into the inside of the groove 42. A through groove 49 for facilitating the movement of the sliding plate 43 is arranged at a position near the top end of the front end of the sliding plate 43. When the sliding plate 43 is inside the device, a hook can be used to penetrate the through groove 49 to pull the sliding plate 43 to move it upwards. Multiple groups of positioning assemblies 4 are provided, and multiple groups of positioning assemblies 4 are symmetrically arranged with the center line of the charge barrel 1 as the axis of symmetry. A round hole 51 is arranged at the top end of the support plate 5, and the detonating fuse 3 passes through the round hole 51. The top end of the detonating fuse 3 needs to exceed the top end of the charge barrel 1.

[0033] Working principle: During actual operation, the sliding plate 43 needs to be inserted into the charge barrel 1 from the bottom end of the charge barrel 1, and the positions of multiple groups of sliding plates 43 are adjusted to determine the installation position. After the position of the sliding plate 43 is adjusted, a set of explosives 2 can be installed at the bottom end of the charge barrel 1 first, and then a set of support plates 5 can be placed. When placing the support plate 5, the support plate 5 needs to be sleeved on the outer wall of the detonating fuse 3, and then the medium material can be filled. After that, a set of explosives 2 can be installed and placed. Repeating the operation in the order of explosives 2, support plate 5, medium material, support plate 5 can complete the loading of the explosives 2.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
