Description

Technical Field

[0002] An intelligent mine is premised and based on mine digitization and informatization, and actively senses, automatically analyzes, and quickly processes mine production, occupational health and safety, technical support, and logistics support, etc. Building an intelligent mine ultimately realizes the construction of a safe mine, unmanned mine, efficient mine, and clean mine. Mines include coal mines, metal mines, non-metal mines, building material mines, chemical mines, etc. Blasting is a technology that uses the compression, loosening, destruction, throwing, and killing effects generated by the explosion of explosives in air, water, earth-rock media, or objects to achieve the desired purpose. When a cartridge or charge explodes in earth-rock media or a structure, it causes phenomena such as compression, deformation, damage, loosening, and throwing of the earth-rock media or structure, and it is the main method used for mine exploitation.

[0003] However, when installing blasting explosives, the traditional method is to first drill a blasting hole and then put in the detonator. Sometimes the burial distance of the detonator is 5 - 10 m inside the mountain body, and the detonator is likely to get stuck after being inserted into the hole, resulting in difficulty in properly installing and burying the detonator and affecting the subsequent blasting effect.

[0004] Therefore, a charging device for intelligent mine blasting is proposed. Summary of the Utility Model

The terms "first", "second", etc. in the specification, claims or drawings of this application are used to distinguish different objects and not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the utility model provides a charging device for blasting in an intelligent mine, as Figures 1 - 4 shown, which includes an extension rod 1. One end of the extension rod 1 is welded with a first limiting cover 2, and the top of the first limiting cover 2 is hinged with a second limiting cover 3. Positioning rods 4 are welded on the outer walls of the first limiting cover 2 and the second limiting cover 3 on the side far from the extension rod 1. The lengths of the first limiting cover 2 and the second limiting cover 3 are the same as the length of the positioning rod 4. Lead through grooves 5 are opened at the central positions of the outer walls of the first limiting cover 2 and the second limiting cover 3 on the side far from the positioning rod 4. A lead guiding groove 6 and a clamping groove 7 are opened on the outer side wall of the extension rod 1. The lead guiding groove 6 is located on one side of the clamping groove 7 and the lead guiding groove 6 communicates with the clamping groove 7. Rubber convex strips 8 are adhesively fixed on the inner side wall of the clamping groove 7. There are two rubber convex strips 8 in total, and the two rubber convex strips 8 are symmetrically arranged on the inner side wall of the clamping groove 7. A push rod 9 penetrates through the extension rod 1 near the lead guiding groove 6. One end of the push rod 9 is threadedly connected with a handle 10. Grooves 11 are opened on the inner side walls of the first limiting cover 2 and the second limiting cover 3 near the positioning rod 4. A stop block 12 is rotatably connected to the inner side wall of the groove 11. A torsion spring 13 is arranged between the stop block 12 and the groove 11.

[0022] It should be noted that since the existing detonators are prone to jamming after being sent into the cave, it is difficult to install and bury the detonators in place, affecting the subsequent blasting effect. In this embodiment, the first limiting cover 2 and the second limiting cover 3 are used to limit the detonator, which can ensure the stability of the detonator during the charging movement in the mine cave, avoid collision and falling off, and use the positioning rod 4 and the push rod 9 to position and push the detonator deep into the cave, avoiding jamming of the detonator during the charging in the cave, ensuring that the detonator is charged in place, and thus ensuring the subsequent blasting effect.

[0023] Specifically, in this embodiment, the solution mainly includes a first limiting cover 2, a second limiting cover 3 and a push rod 9. When blasting and charging the mine, the second limiting cover 3 is opened, the detonator for blasting is placed inside the first limiting cover 2, the detonator lead is passed through the lead wire slot 5 and then clamped into the card slot 7, and the rubber convex strip 8 is used to limit the detonator lead inside the lead wire guide groove 6. The first limiting cover 2 and the second limiting cover 3 are closed by hinging, and the first limiting cover 2 and the second limiting cover 3 are inserted into the cave opened by the mine blasting together, and the first limiting cover 2 and the second limiting cover 3 are inserted deep into the cave by using the extension rod 1. As the first limiting cover 2 and the second limiting cover 3 are inserted, one end of the positioning rod 4 contacts the inner side wall of the deep part of the cave. At this time, hold the handle 10 and push the handle 10. The push rod 9 at one end of the handle 10 moves towards the inside of the first limiting cover 2. During the movement, the push rod 9 contacts and pushes the detonator. The detonator is pushed to squeeze the stop block 12 under the push. The stop block 12 rotates under the force, and the torsion spring 13 is compressed. The stop block 12 rotates to be parallel to the inner side walls of the first limiting cover 2 and the second limiting cover 3. After the detonator is pushed out of the first limiting cover 2 and the second limiting cover 3, it enters the cave, and the detonator is loaded deep into the cave. After the charging is completed, the extension rod 1, the first limiting cover 2 and the second limiting cover 3 can be pulled out of the mine cave.

[0024] In a further preferred embodiment of the present invention, as Figure 1 and Figure 4 shown, the centers of the lead wire guide groove 6 and the lead wire slot 5 are on the same axis, and the lead wire guide groove 6 and the lead wire slot 5 are connected.

[0025] In this embodiment, through the connected structure, the detonator lead can enter the lead wire guide groove 6 after passing through the lead wire slot 5.

[0026] In a further preferred embodiment of the present invention, as Figures 3 - 4 shown, the cross section of the rubber convex strip 8 is a triangular structure.

[0027] In this embodiment, the triangular structure of the triangular structure can provide a limiting resistance for the detonator lead, avoiding the detonator lead falling off from the lead wire guide groove 6.

[0028] In a further preferred embodiment of the present invention, as Figure 2As shown, one end of the torsion spring 13 is embedded in the outer sidewall of the stop block 12, and the other end of the torsion spring 13 is embedded in the inner sidewall of the groove 11.

[0029] In this embodiment, the deformation force of the torsion spring 13 provides resistance for limiting the detonator inside the first limiting cover 2 and the second limiting cover 3, and also facilitates the detonator to be pushed out of the first limiting cover 2 and the second limiting cover 3.
