Description

Technical Field

[0001] This application belongs to the technical field of rock blasting borehole structure, and particularly relates to a rock blasting borehole structure. Background Technology

[0002] In rock blasting engineering, the design and arrangement of parameters such as the layout, depth, diameter, direction, and charge structure of blast holes are crucial. The rational selection and arrangement of these parameters have a direct impact on the blasting effect. Blast holes can be classified into three categories based on their depth and diameter: shallow holes, medium-deep holes, and deep holes. On the tunnel blasting face, blast holes can be classified into cut holes, auxiliary holes, and peripheral holes according to their location and function.

[0003] Currently, in the existing rock blasting process, the explosives used for blasting are usually placed in the blast hole, and then auxiliary work and the installation and connection of other explosives are carried out. It is also necessary to control the uniform detonation time of all explosives. Therefore, it is necessary to temporarily store the explosives in the blast hole for a period of time. However, the current blast hole structure is not convenient for stable temporary storage, and there may be situations where the explosives are affected during temporary storage.

[0004] Therefore, we propose a rock blasting borehole structure to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve the problem of the inconvenience of stable temporary storage and protection of explosives in the prior art, and to propose a rock blasting borehole structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rock blasting borehole structure includes a rock mass body, a borehole body formed on the upper surface of the rock mass body, a temporary storage cylinder inside the borehole body, a support ring fixedly connected to the upper surface of the temporary storage cylinder, the bottom surface of the support ring contacting the upper surface of the rock mass body, a limit ring fixedly connected to the inner wall of the temporary storage cylinder, a plastic cylinder inside the temporary storage cylinder, a sealing plate threadedly connected to the inner wall of the plastic cylinder, a waterproof layer fixedly connected to the outer surface of the plastic cylinder, and four stops fixedly connected to the outer surface of the plastic cylinder, the outer surface of each stop being slidably connected to the inner wall of the limit ring.

[0008] Preferably, the outer surface of the temporary storage cylinder is fixedly connected with an anti-wear layer, and the outer surface of the anti-wear layer is in contact with the inner wall of the borehole body.

[0009] Preferably, five scrapers are fixedly connected to the outer surface of the support ring, and the bottom surface of each scraper is in contact with the upper surface of the rock mass.

[0010] Preferably, the outer surfaces of the five scrapers are all fixedly connected to a rotating ring, and the outer surface of the rotating ring is rotatably connected to the inner wall of the support ring.

[0011] Preferably, a baffle is slidably connected to the inner wall of the rotating ring, and a first threading hole is provided on the upper surface of the baffle.

[0012] Preferably, two push plates are fixedly connected to the outer surface of the baffle, and two anti-slip pads are fixedly connected to the outer surface of each push plate.

[0013] Preferably, the upper surface of the sealing plate is provided with a second wire hole, and two fixing posts are fixedly connected to the upper surface of the sealing plate.

[0014] In summary, the technical effects and advantages of this application are as follows:

[0015] 1. By setting up a temporary storage cylinder, a support ring, a limiting ring, a plastic cylinder, and a stop block, the support ring can support the temporary storage cylinder, preventing it from falling completely into the borehole body. At the same time, when the operator inserts the plastic cylinder and the explosive inside the plastic cylinder into the temporary storage cylinder, the stop block at the bottom of the plastic cylinder can enter the limiting ring through the groove of the limiting ring. By rotating the plastic cylinder and the stop block at a certain angle, the limiting ring can limit the stop block and the plastic cylinder, thereby placing the plastic cylinder into the temporary storage cylinder for temporary storage, and also facilitating and stably storing the explosive inside the plastic cylinder.

[0016] 2. By setting up a sealing plate and a waterproof layer, the waterproof layer can enhance the waterproof effect around the plastic cylinder, thereby increasing the stability and protection of the device when temporarily storing explosives. In addition, the sealing plate can cover the top of the plastic cylinder to prevent stones or foreign objects from entering the plastic cylinder and causing damage, thereby improving the temporary storage effect of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A rock blasting borehole structure includes a rock body 1, a borehole body 6 formed on the upper surface of the rock body 1, a temporary storage cylinder 7 inside the borehole body 6, and an anti-wear layer 8 fixedly connected to the outer surface of the temporary storage cylinder 7. The outer surface of the anti-wear layer 8 is in contact with the inner wall of the borehole body 6. The anti-wear layer 8 is a material layer used to protect the surface of an object from wear. Blue chrome mud anti-wear layer is an anti-wear material sprayed on the surface of the casing, which has the advantages of wear resistance, high temperature resistance and corrosion resistance.

[0024] A support ring 2 is fixedly connected to the upper surface of the temporary storage cylinder 7. Five scrapers 3 are fixedly connected to the outer surface of the support ring 2. The bottom surface of each scraper 3 is in contact with the upper surface of the rock body 1. By setting the scrapers 3, small gravel around the device can be easily scraped away, which makes it easier to place the device and also increases the stability of the device.

[0025] The bottom surface of the support ring 2 is in contact with the upper surface of the rock body 1. The inner wall of the temporary storage cylinder 7 is fixedly connected with a limit ring 12. The outer surfaces of the five scrapers 3 are all fixedly connected with a rotating ring 4. The outer surface of the rotating ring 4 is rotatably connected to the inner wall of the support ring 2. By setting the rotating ring 4, it is easy to drive the scraper 3 to move, so that the cleaning work can be carried out quickly.

[0026] The storage cylinder 7 has a plastic cylinder 17 inside. The inner wall of the plastic cylinder 17 is threaded with a sealing plate 13. The inner wall of the rotating ring 4 is slidably connected with a baffle 5. The upper surface of the baffle 5 has a first wire hole 9. By setting the baffle 5 and the first wire hole 9, the baffle 5 can seal and block the surface of the rotating ring 4. At the same time, the first wire hole 9 can facilitate the lead wire to be drawn out for measurement during temporary storage.

[0027] A waterproof layer 16 is fixedly connected to the outer surface of the plastic cylinder 17. By setting the waterproof layer 16, the waterproof layer 16 can further increase the waterproof effect of the plastic cylinder 17. At the same time, the waterproof layer 16 is generally made of rubber or plastic materials. Four blocks 18 are fixedly connected to the outer surface of the plastic cylinder 17. Two push plates 10 are fixedly connected to the outer surface of the baffle 5. Two anti-slip pads 11 are fixedly connected to the outer surface of each push plate 10. By setting the push plate 10 and the anti-slip pads 11, the push plate 10 can easily push the baffle 5 and the rotating ring 4 to rotate, and the anti-slip pads 11 prevent the hand from slipping.

[0028] The outer surface of each stop 18 is slidably connected to the inner wall of the limiting ring 12. The upper surface of the sealing plate 13 is provided with a second wire hole 14. Two fixing posts 15 are fixedly connected to the upper surface of the sealing plate 13. By setting the second wire hole 14 and the fixing posts 15, the second wire hole 14 can facilitate the threading of the explosive fuse, and the fixing posts 15 can facilitate the rotation of the sealing plate 13 for disassembly and installation.

[0029] The working principle of this utility model is as follows: In use, the operator first places the temporary storage cylinder 7 to a suitable position. Then, the operator inserts the temporary storage cylinder 7 into the borehole body 6 of the rock mass 1. The support ring 2 supports the temporary storage cylinder 7, preventing it from falling completely into the borehole body 6. Next, the operator inserts the plastic cylinder 17 containing the explosive into the temporary storage cylinder 7. When the operator inserts the plastic cylinder 17 and the explosive inside it into the temporary storage cylinder 7, the stop block 18 at the bottom of the plastic cylinder 17 can enter the limiting ring 12 through the groove. The plastic cylinder 17 and the stop block 18 are rotated at a certain angle, allowing the limiting ring 12 to limit the stop block 18 and the plastic cylinder 17, thus allowing the plastic cylinder 17 to be placed into the temporary storage cylinder. 7. Temporary storage is performed. Then, the staff passes the reserved fuse of the explosive through the second threading hole 14 and connects the sealing plate 13 to the plastic cylinder 17. Since the second threading hole 14 is relatively small, the sealing plate 13 can block the top of the plastic cylinder 17 to prevent stones or foreign objects from entering the plastic cylinder 17 and causing damage. Finally, the reserved fuse is passed through the first threading hole 9 and the baffle 5 is placed on the rotating ring 4, which facilitates the temporary storage of the explosive. After the preparation and storage work is completed, the staff removes the baffle 5 and rotates the plastic cylinder 17. When the stop block 18 at the bottom of the plastic cylinder 17 moves to the groove below the limiting ring 12, it will fall out from the inside of the limiting ring 12. Then, the temporary storage cylinder 7 is taken out, and finally, the reserved fuse is connected to the external detonation fuse for detonation.
