[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, this embodiment proposes a vibration-damping charging structure for blasting in medium and large tunnels, including a support plate 1, a bracket 2 is fixedly connected to the side of the support plate 1, a charge pack assembly 3 is provided on the side of the support plate 1, the charge pack assembly 3 includes a placement plate 31, the side of the placement plate 31 is fixedly connected to the side of the support plate 1, a rectangular frame 32 is fixedly connected to the side of the support plate 1, a spring 1 33 is fixedly connected to the side of the rectangular frame 32, an end of the spring 1 33 away from the rectangular frame 32 is fixedly connected to a cross plate 34, a top of the cross plate 34 is fixedly connected to a splint 36, an end of the bracket 2 away from the support plate 1 is fixedly connected to a charge pack 37, and a side of the cross plate 34 is fixedly connected to a handle 35.

[0028] The placement plate 31 is located below the medicine package 37. Two rectangular frames 32 and springs 33 are provided and are symmetrical to each other along the vertical center axis of the support plate 1. The placement plate 31 is below the medicine package 37, which is conducive to supporting the medicine package 37 so that the medicine package 37 can be placed on the support plate 1.

[0029] There are several explosive bags 37, placement plates 31, and brackets 2, and several explosive bags 37 are arranged on the side of the support plate 1 along a linear array, which is beneficial to enhancing the blasting effect and is suitable for tunnels that require strong blasting force.

[0030] There are two clamping plates 36 and two cross plates 34, which are symmetrical to each other along the vertical center axis of the support plate 1. The explosive bag 37 is located on the displacement track of the clamping plates 36. Two clamping plates 36 are provided, which can clamp the entire structure and the explosive bag 37 in a certain place, thereby fixing it in the tunnel that needs to be blasted.

[0031] In this embodiment, several medicine bags 37 are placed on the placement plate 31 respectively, and the two handles 35 are held by hand, and the handles 35 and the cross plate 34 are pulled to make opposite movements, so that the two handles 35 and the cross plate 34 make opposite movements.

The operator can easily adjust the splint 36 to quickly install and remove the medicine bag 37, saving construction time and improving work efficiency.

[0032] Example 2

[0033] like Figure 2 、 Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fixed anti-displacement component 4 is provided on the side of the support plate 1, and the fixed anti-displacement component 4 includes a vertical rod 41, one end of the vertical rod 41 is fixedly connected to the side of the splint 36, and the side of the vertical rod 41 is fixedly connected to a round rod 411, and the end of the round rod 411 away from the vertical rod 41 is fixedly connected to a telescopic rod 412, and the end of the telescopic rod 412 away from the round rod 411 is fixedly connected to an extrusion block 413, and the side of the support plate 1 is fixedly connected to a cylindrical rod 410, the end of the cylindrical rod 410 away from the support plate 1 is fixedly connected to the vertical rod 42, the inner wall of the vertical rod 42 is rotatably connected to the turntable 43, the circumferential surface of the turntable 43 is fixedly connected to the long rod 44, the bottom of the long rod 44 is fixedly connected to the inclined block 45, the circumferential surface of the turntable 43 is fixedly connected to the connecting rod 46, the end of the connecting rod 46 away from the turntable 43 is fixedly connected to the fixing plate 47, the design of the fixing plate 47 is convenient for fixing the medicine bag 37 on the support plate 1 to prevent the medicine bag 37 from shaking and displacement.

[0034] The medicine package 37 is located on the displacement track of the fixed plate 47, the inclined block 45 is located on the displacement track of the extrusion block 413, and the medicine package 37 is located on the displacement track of the fixed plate 47, which makes it convenient to press and fix the medicine package 37 when the fixed plate 47 moves.

[0035] A support plate 48 is fixedly connected to the side of the vertical rod 42, and a spring 2 49 is fixedly connected to the side of the support plate 48. The end of the spring 2 49 away from the support plate 48 is fixedly connected to the side of the connecting rod 46. The design of the spring 2 49 makes it convenient for the connecting rod 46 to automatically reset when the connecting rod 46 is not driven.

[0036] The fixing plate 47 is located on the side of the splint 36 , and the fixing plate 47 is located on the side of the medicine bag 37 . The fixing plate 47 is located on the side of the splint 36 and will not affect the operation of the splint 36 .

When the extrusion block 413 moves in the opposite direction, it will squeeze the inclined block 45. The inclined block 45 is provided with an inclined surface, and the extrusion block 413 is also provided with an inclined surface. Through the influence of the two inclined surfaces, when the extrusion block 413 moves, the inclined block 45 will be squeezed to move upward, so that the long rod 44 moves upward. The upward movement of the long rod 44 will drive the turntable 43 to rotate upward. The upward rotation of the turntable 43 will drive the connecting rod 46 and the fixed plate 47 to move to the side close to the medicine bag 37, and the fixed plate 47 will be used to hold a plurality of medicine bags. The bag 37 is pressed and fixed, so that the medicine bag 37 can be firmly installed on the support plate 1, reducing displacement and shaking. The opposite movement of the splint 36 drives the relative movement of the extrusion block 413, and finally pushes the inclined block 45 upward through the cooperation of the inclined surface, thereby driving the long rod 44 and the turntable 43 to move, and then pushes the fixed plate 47 toward the medicine bag 37 and presses it. This process can ensure that multiple medicine bags 37 are firmly fixed on the support plate 1, effectively reducing the displacement and shaking of the medicine bag 37 caused by vibration or movement during the tunnel blasting process, ensuring that the medicine bag 37 always remains in a precise position during the blasting process, so that the medicine bag 37 can always be in appropriate pressure and position during the entire blasting process, ensuring the reliability of the medicine bag 37 device, and reducing incomplete or deviation blasting caused by position offset or insufficient pressure of the medicine bag 37.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
