Description

Technical Field

[0001] The utility model relates to the technical field of blasting devices, in particular to a concentrated energy blasting device capable of adjusting the direction of a concentrated energy jet. Background Art

[0002] Blasting hazard control has always been an important topic studied by the engineering blasting community. Controlling blasting hazards is crucial in the construction of hydropower, railways, mining and other projects. For example, when the tunnel is excavated using the drilling and blasting method, the blasting excavation of explosives will inevitably cause damage and deformation to the tunnel's reserved surrounding rock. The violent explosion energy deteriorates the mechanical properties of the reserved rock mass. In serious cases, it will cause the tunnel structure to be destroyed and the surrounding rock to be unstable and damaged, which will cause significant economic losses. Therefore, a shaped charge blasting device is needed. Some traditional shaped charge blasting devices have the function of adjusting the direction of the shaped charge jet, but the adjustment is generally to determine the direction of the V-shaped shaped charge groove buckle before inserting it into the blast hole, and then insert it into the blast hole. After inserting the blast hole, the shaped charge blasting device has a huge friction with the blast hole wall, and generally cannot be rotated to change the direction of the V-shaped shaped charge groove buckle. Therefore, it is necessary to be very careful when installing the shaped charge blasting device into the blast hole. However, because it is installed by combining manual and mechanical means, it is inevitable that inaccurate installation will occur. At this time, it takes more time and manual work to make adjustments, resulting in low installation efficiency.

[0003] Therefore, it is necessary to develop a focused energy blasting device that can adjust the direction of the focused energy jet to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the above problems and designs a focused energy blasting device capable of adjusting the direction of the focused energy jet.

[0007] Blasting tube; the blasting tube is formed into a cylindrical ring structure;

[0008] Energy gathering device; the energy gathering device is formed into a cylindrical ring structure, the outer diameter of the energy gathering device is slightly smaller than the inner diameter of the blasting tube, and the energy gathering device is rotatably axially installed inside the blasting tube;

[0009] The charge cartridge is axially mounted in the middle of the energy focusing device;

[0010] Multiple spaced charge structures; multiple spaced charge structures are axially installed in the charge barrel.

[0011] Preferably, a flange plate is protruding outward from the first end of the energy gathering device, and a slip ring is provided on the side of the flange plate facing the second end of the energy gathering device. Correspondingly, an annular groove is provided on the end face of the first end of the blasting tube, and the slip ring is rotatably installed in the groove.

[0012] Furthermore, the shaped-charge blasting device further comprises a fixing device, which is formed into a cylindrical structure with one end open, and the fixing device is fixedly sleeved on the second end of the blasting tube.

[0013] Furthermore, an internal thread is arranged on the inner wall of the opening end of the fixing device, an external thread is arranged on the outer wall of the second end of the blasting tube, and the opening end of the fixing device is threadably connected to the second end of the blasting tube.

After the blasting device is loaded into the blast hole, the operator can rotate the energy-gathering device to a certain angle to adjust the opening direction of the energy-gathering device, and then adjust the direction of the energy-gathering jet. This avoids the operation in the prior art that the blasting device can only be loaded into the blast hole according to the set angle, and the cumbersome adjustment process after the loading angle is incorrect, thereby speeding up the installation efficiency overall.

[0032] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-5 As shown, a shaped energy blasting device capable of adjusting the direction of shaped energy jet comprises:

[0034] Blasting tube 1; Blasting tube 1 is formed into a cylindrical ring structure;

[0035] Energy gathering device 3; the energy gathering device 3 is formed into a cylindrical ring structure, the outer diameter of the energy gathering device 3 is slightly smaller than the inner diameter of the blasting tube 1, and the energy gathering device 3 is rotatably installed axially inside the blasting tube 1; and a flange plate is protruding outwardly provided at the first end of the energy gathering device 3, and a slip ring 8 is provided on the side of the flange plate facing the second end of the energy gathering device 3, and correspondingly, an annular groove 9 is provided on the end surface of the first end of the blasting tube 1, and the slip ring 8 is rotatably installed in the groove 9;

[0036] The charge cartridge 4 is axially mounted in the middle of the energy gathering device 3;

[0037] Multiple spaced charge structures; multiple spaced charge structures are axially mounted in the charge barrel 4; the spaced charge structure comprises explosive 5, a partition, a spacer medium 7, and a partition connected in sequence; the spacer medium 7 is preferably air or water;

[0038] Fixing device 2; the fixing device 2 is formed into a cylindrical structure with one end open, an inner thread is provided on the inner wall of the open end of the fixing device 2, an outer thread is provided on the outer wall of the second end of the blasting tube 1, and the open end of the fixing device 2 is threadedly connected with the second end of the blasting tube 1. A fixing seat 11 is provided at the bottom center of the fixing device 2, and the fixing seat 11 is formed into a cylindrical structure, and the inner diameter of the fixing seat 11 is slightly larger than the outer diameter of the charge cartridge 4, and one end of the charge cartridge 4 is placed inside the fixing seat 11 for position fixing.

[0039] In this embodiment, the charge cartridge 4 and the blasting cartridge 1 are made of plastic, and the energy gathering device 3 is made of PVC material.

[0040] Working principle: Taking advantage of the fact that the explosive products will move along the outer normal direction of the surface of the explosive 5 during the blasting process, the sliding ring 8 of the energy gathering device 3 rotates in the annular groove 9 and is fixed at the expected position, so as to gather the blasting energy in a specific direction, thereby enhancing the effect of the explosive force. At the same time, the spacer medium 7 is used to separate the sections of the charge roll in the charge barrel 4 to reduce the initial pressure of the stress wave and the gas products of the detonation on the blast hole wall, so that the crushing area around the blast hole is significantly reduced or even no crushing area is generated, so as to reduce the charge amount of the blast hole while improving the effective utilization rate of the energy of the explosive 5.

[0041] Installation process: first load a detonating cord into the charge barrel 4, and then sequentially insert the baffle, spacing medium 7, baffle, and explosive 5 into the charge barrel 4 until the expected charge amount is reached, and then place the charge barrel 4 in the blasting tube 1 with a preset energy-gathering device 3, fix the bottom of the charge barrel 4 with a fixing seat 11 and buckle it on the blasting tube 1 to fix it before loading it into the blast hole, and according to the energy-gathering blasting effect required to be achieved in the blast hole, rotate the slip ring 8 of the energy-gathering blasting device and fix it in the slot 9. The fixation here refers to the friction between the slip ring and the slot, and relies on the friction to ensure that the slip ring and the slot will not rotate relative to each other without human rotation.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
