[0023] Among them, see Figure 2The limiting member 8 includes a first limiting hook 81, an annular stopper 82 and a telescopic member 83 (such as an electric telescopic rod). The middle part of the first limiting hook 81 is hinged on the side wall of the mounting tube 5 through a pin shaft. One end of the first limiting hook 81 extends into the inner cavity of the mounting tube 5 and fits with the bottom wall of the movable seat 7. The annular stopper 82 is slidably sleeved on the outer wall of the mounting tube 5 (the annular stopper 82 can move up and down). The annular stopper 82 is located on the inner side of the other end of the first limiting hook 81, and is used to limit the rotation of the first limiting hook 81, so that the first limiting hook 81 supports the movable seat 7 and prevents it from moving downward; the telescopic member 83 is arranged on the mounting tube 5, and the moving end of the telescopic member 83 is connected to the annular stopper 82.

[0024] It should be noted that the telescopic member 83 drives the annular stopper 82 to move so that it is not in contact with the first limit hook 81, thereby releasing the restriction on the first limit hook 81 and causing the supporting force of the first limit hook 81 on the movable seat 7 to disappear. Under the action of the second elastic member 6, the movable seat 7 moves downward, pulling the second pull rope 13 to drive the support leg 3 to rotate and unfold, so that the end of the support leg 3 contacts the side wall of the chute, fixing the explosive bracket in the chute to support the explosive.

[0025] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The support leg 3 includes a sleeve 31, a moving rod 32 slidably inserted in the sleeve 31, and a first elastic member 33 (spring) arranged between the sleeve 31 and the moving rod 32. The first set 4 is fixedly sleeved on the outer wall of the sleeve 31, and the second limit hook 14 is hinged on the first set 4 (the middle part of the second limit hook 14 is hinged on the first set 4 through a pin shaft). A slot is opened on the side wall of the moving rod 32, one end of the second limit hook 14 is inserted into the inner cavity of the slot, and a first pull rope 12 is arranged between the other end of the second limit hook 14 and the mounting seat 1; by putting the moving rod 32 into the inner cavity of the sleeve 31, the overall support leg 3 is reduced. length; at the same time, due to the reduction in the length of the leg 3, the leg 3 can be rotated and fully unfolded; in the process of the second pull rope 13 pulling the leg 3 to rotate and unfold, the first pull rope 12 will gradually tighten. When the first pull rope 12 is tightened, the second limit hook 14 will be pulled and rotated out of the slot, releasing the restriction on the moving rod 32. Under the push of the first elastic member 33, the moving rod 32 moves toward the outside of the inner cavity of the sleeve 31 and contacts the side wall of the chute, so that the leg 3 is extended and inserted into the side wall of the chute, instead of the leg 3 rotating and contacting the side wall of the chute, so that the leg 3 is more fully unfolded, increasing the stability of the explosive bracket fixation.

[0026] In this embodiment, as a further optimized solution, please refer to Figure 6A second set 15 is fixedly sleeved on the outer wall of the sleeve 31, and a limiting plug 17 is slidably provided on the second set 15. An elastic element 16 (spring) is provided between the second set 15 and the limiting plug 17. The thrust provided by the elastic element 16 is used to make the limiting plug 17 move closer to the moving rod 32. A plurality of insertion holes are provided on the side wall of the moving rod 32. The plurality of insertion holes are arranged in sequence along the length direction of the moving rod 32. The inner end of the limiting plug 17 faces a side wall of the sleeve 31 and is arc-shaped (the inner end of the limiting plug 17 refers to the end where the limiting plug 17 contacts the moving rod 32); the limiting plug 17 is inserted into a insertion hole to limit the moving rod 32 from moving into the inner cavity of the sleeve 31. Because the side of the limiting plug 17 facing the sleeve 31 is an arc-shaped surface, when the moving rod 32 moves toward the outside of the sleeve 31 under the action of the first elastic member 33, the limiting plug 17 will move out of the insertion hole, so that the outward movement of the moving rod 32 is not affected.

[0027] In this embodiment, as a further optimized solution, please refer to Figure 6 The end of the moving rod 32 away from the sleeve 31 is tapered, which facilitates the insertion of the moving rod 32 into the inner wall of the ore chute.

[0028] In this embodiment, as a further optimized solution, please refer to Figure 3 A camera 9 and a power supply device 10 (battery) are provided on the mounting tube 5. The power supply device 10 is used to supply power to the electrical equipment on the explosive bracket. The camera 9 is used to photograph the situation in the blocked area and feed it back to the staff so that the staff can remotely adjust the installation equipment to ensure that the explosives are close to the blocked area and ensure the dredging effect of the mine chute.

[0029] Working principle: fix the explosive bracket to the telescopic arm of the remote control vehicle (the mounting tube 5 of the explosive bracket is snap-connected with the moving end of the telescopic arm, that is, a card block is provided on the mounting tube 5, and a card slot is provided at the moving end of the telescopic arm, and the card block is inserted into the card slot, and the friction force of contact between the two is used to realize the connection between the mounting tube 5 and the telescopic arm), and then fix the explosive on the bracket 2; after the staff remotely controls the remote control vehicle to move into the interior of the chute, the telescopic arm extends, driving the explosive bracket to move upward, and after the explosive approaches the bottom of the blocked area, the telescopic arm stops extending; the telescopic member 83 drives the annular stopper 82 to move so that it does not contact the first limit hook 81, thereby releasing the restriction on the first limit hook 81, so that the first limit hook 81 supports the moving seat 7 The force disappears, and under the action of the second elastic member 6, the movable seat 7 moves downward, pulling the second pull rope 13, driving the supporting leg 3 to rotate and unfold; in the process of the second pull rope 13 pulling the supporting leg 3 to rotate and unfold, the first pull rope 12 will gradually tighten, and when the first pull rope 12 is tightened, the second limit hook 14 will be pulled and rotated out of the slot, releasing the restriction on the movable rod 32, and under the push of the first elastic member 33, the movable rod 32 moves toward the outside of the inner cavity of the sleeve 31 and contacts the side wall of the chute, fixing the explosive bracket in the chute for supporting the explosive; then the telescopic arm contracts to separate the telescopic arm from the explosive bracket, and after the remote control vehicle moves out of the interior of the chute with the telescopic arm, the explosive is detonated to dredge the chute.
