Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a charging device for blasting in mining. Background Technology

[0002] In mining operations, blasting is a crucial step in breaking up ore and rock, and loading explosives is the core step in blasting operations. Currently, the common method of loading explosives is to directly pour them into the borehole. While simple, this method is prone to inaccurate control of the explosive's position in practice. Firstly, due to the lack of precise control methods, the explosive's position within the borehole is easily misaligned, affecting the uniformity and effectiveness of the blast. Secondly, directly pouring the explosives prevents flexible adjustment of their position within the borehole according to the blasting design, making it difficult to meet different blasting requirements and reducing blasting accuracy. Furthermore, the distribution of the explosives directly affects the blast's power and direction; inaccurate placement can lead to uncontrolled blasting range, increasing the risk of accidents such as flying rocks.

[0003] Therefore, there is an urgent need for a new type of explosive charging device for blasting in mining, which can precisely control the position of explosives, flexibly adjust the distribution of explosives in the borehole according to the actual situation, and is easy to operate and stable and reliable, so as to meet the needs of blasting operations in different environments.

Detailed Implementation

[0016] To make the technical problems and solutions solved by this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1-4 As shown, this utility model provides a charging device for blasting in mining operations, including an explosive tube 1, a fixing sleeve 2 sleeved on the outside of the explosive tube 1, a plurality of locking blocks 12 connected to the top of the fixing sleeve 2, and a plurality of locking grooves 13 opened on the top edge of the explosive tube 1. The locking blocks 12 are engaged with the locking grooves 13, the fixing sleeve 2 and the explosive tube 1 are stably connected, and the two are effectively prevented from rotating or shifting during use, which significantly improves the stability of the device.

[0020] Two support rods 3 are connected to the outside of the fixed sleeve 2. The top of the two support rods 3 is connected to the same support frame 4. A fixed seat 5 is connected inside the support frame 4. A cylinder 6 is installed through the fixed seat 5. Specifically, the base of the cylinder 6 is installed above the fixed seat 5, and the cylinder rod passes through the center of the fixed seat 5, thereby ensuring the stability of the cylinder 6 installation.

[0021] The bottom end of the cylinder 6 is equipped with a pneumatic claw 7, which holds two limiting rings 8. The limiting rings 8 are arc-shaped, and each limiting ring 8 has an elastic telescopic rod 9 connected to its inner side. The ends of the two elastic telescopic rods 9 that are close to each other are connected to the same limiting ring 10, and a storage cartridge 11 is connected inside the limiting ring 10. The two limiting rings 8 have grooves for the pneumatic claw 7 to grip, and when the pneumatic claw 7 is gripped in the groove, its outer surface is the same circumference as the outer arc surface of the limiting ring 8. The extension and retraction of the cylinder 6 can drive the storage cartridge 11 to move inside the explosive tube 1, thereby precisely controlling the distribution position of the explosive; at the same time, under the action of the elastic telescopic rods 9, the limiting rings 8 can quickly limit the storage cartridge 11 inside the explosive tube 1, completing the precise placement of the explosive.

[0022] Furthermore, to intuitively and accurately read the placement position of the explosive, an L-shaped movable rod 14 is connected to the top of the pneumatic gripper 7. The other end of the movable rod 14 is connected to a movable sleeve 15, within which a measuring rod 16 is slidably mounted. The measuring rod 16 has a measuring scale, and support columns 17 are connected to both sides of the measuring rod 16. The other ends of the two support columns 17 are connected to the inner side of the support frame 4. When the pneumatic gripper 7 moves, the movable rod 14 follows, causing the movable sleeve 15 to slide along the measuring rod 16. When the movement stops, the position reading of the movable sleeve 15 relative to the measuring rod 16 is the depth of the explosive placement within the explosive tube 1.

[0023] Working principle: When using this device, first place the explosive tube 1 into the borehole, then fit the fixing sleeve 2 onto the outside of the explosive tube 1, and align the locking block 12 into the locking groove 13 to complete the connection between the fixing sleeve 2 and the explosive tube 1. At this time, the cylinder 6 is in the retracted state, which can fill the explosive storage cylinder 11 with explosive. Activate the pneumatic jaw 7 to clamp the limiting ring 8, compressing the elastic telescopic rod 9, thereby causing the limiting ring 8 to shrink to a size smaller than the inner diameter of the explosive tube 1. Activate the cylinder 6, which extends downward to push the pneumatic jaw 7 downward, causing the explosive storage cylinder 11 to move inside the explosive tube 1, and simultaneously causing the moving rod 14 and the moving sleeve 15 to slide downward along the measuring rod 16. When the reading of the measuring rod 16 is the designed depth value, slowly release the pneumatic jaw 7, allowing it to slowly exit the locking groove of the limiting ring 8. During this process, the limiting ring 8 extends outward under the elastic restoring force of the elastic telescopic rod 9 until it is tightly locked onto the inner wall of the explosive tube 1, thereby precisely limiting the explosive-filled storage cylinder 11 inside the explosive tube 1. Repeating the above operation allows multiple explosive-filled storage cylinders 11 to be precisely positioned at appropriate locations on the explosive tube 1. After placement, the cylinder 6 drives the pneumatic claw 7 and the moving rod 14 to retract away from the explosive tube 1, and the fixing sleeve 2 can be removed by prying open the locking block 12.

[0024] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
