Description

Technical Field

[0001] This utility model relates to the technical field of blasting drilling devices, specifically a drilling device for blasting operations. Background Technology

[0002] During mountain blasting, holes are typically drilled in the mountainside to facilitate the placement of explosives. Explosives are then placed inside these holes, and detonation blasts the mountain open to facilitate road or bridge construction or mining. Currently, drilling generates significant dust. If this dust persists, it not only harms the health of construction workers but also affects explosive loading and delays the blasting process. Therefore, dust suppression is usually necessary during drilling. Common methods include water spraying or wetting the drilling site. However, both methods result in dampness in the borehole, which can cause the explosives to become damp after loading, affecting the blasting process and leading to deficiencies in the drilling equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a drilling device for blasting operations, including a protective cylinder. Before drilling, the protective cylinder is fixed to the drilling site by screws or anchor rods. Then, drilling is carried out inside the protective cylinder. The protective cylinder plays a protective role during the operation, reducing dust at the construction site, thereby reducing the impact and harm of dust on construction personnel, and facilitating drilling operations and subsequent explosive loading. The protective cylinder is composed of several protective frames 1 spliced ​​from bottom to top. During use, the height of the protective frames 1 can be flexibly spliced ​​according to the drilling depth and drill bit length. The preferred fixing method during splicing is to fix it by bolt connection.

[0025] One side of the protective frame 1 is open, and a protective plate 2 is installed on the side of the protective frame 1 to cover the open. The protective plate 2 is detachable. As the drilling depth gradually increases, the protective plate 2 can be removed as needed. The working equipment connected to the outside can move within the open side of the protective frame 1 to carry out effective work. A cleaning port is opened on the side of the protective frame 1 at the bottom, and a retaining plate 3 is rotatably installed on the side of the protective frame 1 within the cleaning port. During the drilling operation, the rock and soil generated during drilling can be cleaned through the cleaning port. When cleaning is not required, the retaining plate 3 covers and seals the cleaning port to reduce dust.

[0026] An installation plate 5 is slidably installed inside the protective frame 1. A drilling assembly located inside the protective cylinder is installed on the side of the installation plate 5. The drilling assembly includes a motor unit 6 installed on the side of the installation plate 5. An installation shaft 7 is installed on the output shaft of the motor unit 6. A drill bit assembly 8 is installed at the bottom end of the installation shaft 7. A spiral blade 9 is installed on the side of the installation shaft 7. During drilling operations, the motor unit 6 is controlled to drive the installation shaft 7 to rotate, and the drill bit assembly 8 at the bottom end of the installation shaft 7 performs drilling operations. The spiral blade 9 is used for cleaning and conveying soil and rock during the operation, which facilitates the conveying of soil and rock from the borehole to the outside. Afterwards, the soil and rock outside the borehole can be cleaned through the cleaning port. Preferably, the drill bit assembly 8 is replaceable.

[0027] The mounting plate 5 has a storage component installed on its side outside the protective cylinder. The storage component is used to store the protective plate 2 after it is disassembled. A flange assembly 15 is fixed on the upper side of the mounting plate 5. An external lifting device is connected to the drilling device through the flange assembly 15. The drilling device is then used to control the lifting of the drilling assembly to adjust the drilling position and drilling depth.

[0028] A magnetic strip 4 is installed on the side of the protective frame 1 near the opening. The protective plate 2 is attached to the side of the protective frame 1 by the magnetic strip 4 to cover the opening. Magnets can be set on the side of the protective plate 2 at the position corresponding to the magnetic strip 4, or a magnetic attraction group can be set on the side of the protective plate 2 at the position corresponding to the magnetic strip 4 to ensure that the magnetic strip 4 effectively attracts the protective plate 2. The top of the protective plate 2 has an upward-facing slope, and the bottom of the protective plate 2 has a downward-facing slope, and the slope at the top of the protective plate 2 matches the slope at the bottom of the protective plate 2.

[0029] The storage assembly includes a storage box 10 installed on the side of the mounting plate 5. The storage box 10 is open on the side near the protective frame 1. An elastic pushing component is installed inside the storage box 10. When the mounting plate 5 moves down inside the protective frame 1, the mounting plate 5 applies pressure to the protective plate 2. Affected by the inclined surfaces on the upper and lower sides of the protective plate 2, the protective plate 2 separates from the magnetic strip 4 and moves into the storage box 10. The protective plate 2 can be automatically disassembled during the drilling process, which facilitates the use of this drilling device. When the storage box 10 contains the protective plate 2, when the subsequent protective plate 2 enters the storage box 10, the squeezing and pushing component makes room for the newly entered protective plate 2, which facilitates the storage of multiple protective plates 2.

[0030] The elastic pushing component includes a pressure plate 11 slidably disposed in the lower part of the inner cavity of the storage box 10. A connecting rod 12 is fixed to the side of the pressure plate 11. The connecting rod 12 is slidably connected to the side of the storage box 10 away from the opening. A spring 13 is sleeved on the outside of the connecting rod 12, and the spring 13 is located between the pressure plate 11 and the storage box 10. When the mounting plate 5 moves upward in the protective frame 1, the spring 13 sleeved on the outside of the connecting rod 12 pushes out the protective plate 2 in the storage box 10 in sequence through the pressure plate 11. After being pushed out, the protective plate 2 is attracted and fixed to the magnetic strip 4 on the side of the protective frame 1. The protective plate 2 blocks and protects the opening on the side of the protective frame 1, reducing dust.

[0031] A cleaning plate 14 is fixed to the upper side of the storage box 10. The cleaning plate 14 contacts the side of the magnetic strip 4. When the mounting plate 5 moves the storage box 10 upward, the cleaning plate 14 installed on the side of the storage box 10 cleans the dust and foreign objects on the side of the magnetic strip 4, ensuring that the magnetic strip 4 effectively attracts the protective plate 2 to position it.

[0032] This drilling device, designed for blasting operations, can limit dust generation during drilling, thereby reducing dust at the construction site and facilitating drilling operations. It also does not affect the loading and placement of explosives. Compared to water spraying for dust suppression, it can effectively improve the efficiency of blasting operations and ensure effective blasting. Furthermore, the protective cylinder can be used as a guide during drilling to prevent the drilling position from deviating and causing safety hazards.
