Description

Technical Field

[0001] This utility model relates to the field of mining machinery, specifically to a chemical pack detachment component and a mine chute dredging vehicle. Background Technology

[0002] As the main transportation channel for ore in mines, mine chutes play a crucial role in the mining process. Blockages in mine chutes can severely disrupt normal mine production. Currently, methods for clearing mine chute blockages include mechanical prying, drilling and blasting, bamboo-pole-suspended explosive charge blasting, hydrogen balloon-suspended explosive charge blasting, and mining rockets. Among these, the bamboo-pole-suspended explosive charge blasting method involves using bamboo poles or telescopic rods to carry explosives to the blasting area. During the explosion, the bamboo poles or telescopic rods are needed to support the explosives. However, this can cause the entire bamboo pole or telescopic rod to detonate, increasing the cost of clearing the blockage. Utility Model Content

[0003] The purpose of this invention is to provide a chemical pack detachment component and a mine chute dredging vehicle, which solves the problem of high dredging costs in existing systems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a charge release assembly, comprising: a support rod and a charge fixing rod detachably connected to the end of the support rod, wherein the charge fixing rod is used to hold the explosive charge; The support rod is equipped with a pneumatic actuator, which is used to drive the charge fixing rod to separate from the support rod so that the charge fixing rod and the explosive charge can be installed in the blocked area of ​​the mine chute.

[0005] Preferably, the explosive charge fixing rod includes a cylinder and a baffle located inside the cylinder, the explosive charge is located inside the cylinder and supported by the baffle, and the explosive charge fixing rod is made of PVC.

[0006] Preferably, the cylinder is provided with a top cover for sealing the cylinder.

[0007] Preferably, the support rod includes a separator rod sleeve, a separator rod end disposed on the separator rod sleeve, and an end cap disposed on the separator rod end.

[0008] Preferably, the pneumatic actuator includes a piston slidably disposed within the separator rod sleeve, a piston rod disposed on the piston, and an air inlet disposed on the separator rod sleeve, wherein the separator rod end and end cover are provided with an opening for the piston rod to pass through.

[0009] Preferably, O-rings are provided on both the inner and outer walls of the piston.

[0010] Preferably, a first elastic element is provided between the end of the separating rod and the piston rod.

[0011] Preferably, the end of the separating rod is hinged with a thrust hook for limiting the medicine pack fixing rod, and the end of the separating rod is slidably provided with a top head for abutting the thrust hook and a second elastic element connected to the top head.

[0012] Preferably, a rolling rod is provided at the end of the separator rod sleeve away from the separator rod end, and a bottom cover is provided on the rolling rod.

[0013] Preferably, a mine chute dredging vehicle includes: a vehicle body and a chemical pack release assembly as described above, mounted on the vehicle body.

[0014] The beneficial effects of this utility model are as follows: the explosive charge is stored in the explosive charge by the charge fixing rod, and the charge fixing rod is sleeved on the outer wall of the end of the support rod. Then, the charge fixing rod is driven to separate from the support rod by the pneumatic pusher. This allows the charge fixing rod and the explosive charge to be installed in the blocked area of ​​the mine chute. Compared with the previous method of using the entire telescopic rod or bamboo pole as a disposable consumable, the charge detachment component can now directly detach the front part of the charge fixing rod. The consumable has become a small part of the charge fixing rod, which greatly reduces the cost of clearing the mine chute. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] Please see Figure 1 and Figure 2 A detachment assembly for explosive charges includes: a support rod 1, and an explosive charge fixing rod 8 detachably provided on the outer wall of the end of the support rod 1. For example, the explosive charge fixing rod 8 is sleeved on the outer wall of the end of the support rod 1, and an explosive charge is provided on the explosive charge fixing rod 8. A pneumatic actuator is provided on the support rod 1, and the pneumatic actuator is connected to an external air source.

[0020] It should be noted that the working method of the explosive charge release assembly is as follows: the explosive charge is installed on the explosive charge fixing rod 8, and then the pneumatic pusher is inflated to drive the explosive charge fixing rod 8 upward (when the explosive charge release assembly is working, the support rod 1 is in a vertical state, and the explosive charge fixing rod 8 is located at the top of the support rod 1), until the explosive charge fixing rod 8 separates from the support rod 1, so that the explosive charge fixing rod 8 and the explosive charge are installed in the blocked area of ​​the mine chute. After the installation is completed, the support rod 1 is removed from the mine chute, the explosive charge is detonated, and the blocked mine chute is cleared.

[0021] In this embodiment, as a further optimization, please refer to... Figure 1 The explosive charge fixing rod 8 includes a cylinder and a baffle located inside the cylinder. The explosive charge is placed in the inner cavity of the cylinder and supported by the baffle. A top cover 9 is provided on the end of the cylinder away from the support rod 1. The top cover 9 is connected to the cylinder by screws and is used to seal the opening of the cylinder. The explosive charge fixing rod 8 is made of PVC. In this embodiment, when the explosive charge is installed using the explosive charge release assembly, the explosive charge and the explosive charge fixing rod 8 are left in the dredging area, and the remaining parts of the explosive charge release assembly are recycled. Since the explosive charge fixing rod 8 is made of PVC, its cost is only a few yuan, which is much lower than the cost of the existing bamboo pole which is tens of yuan, greatly reducing the cost of dredging the mine chute.

[0022] It should be noted that the method of fixing the explosive charge fixing rod 8 to the blockage area can be to apply an adhesive (such as glue) to the top cover 9, connect the top cover 9 to the bottom of the ore in the blockage chute through the adhesive, and install the explosive charge fixing rod 8 in the blockage area.

[0023] In this embodiment, as a further optimization, please refer to... Figure 1 The support rod 1 includes a separating rod sleeve 101, a separating rod end 102, and an end cover 103. The separating rod end 102 is screwed into the inner cavity of the separating rod sleeve 101. The end cover 103 is fitted onto the outer wall of the end of the separating rod end 102 away from the separating rod sleeve 101 and is fixed to the separating rod end 102 with screws. The medicine pack fixing rod 8 is fitted onto the outer wall of the end cover 103. The pneumatic actuator includes a piston 3 that slides in the inner cavity of the separating rod sleeve 101 and a piston 3 that slides in the inner cavity of the separating rod sleeve 101. The piston rod 2 on the piston 3 and the air inlet on the separator rod sleeve 101 are provided. The separator rod end 102 and the end cover 103 are both provided with openings for the piston rod 2 to pass through the separator rod end 102 and the end cover 103. External equipment injects gas into the separator rod sleeve 101 through the air inlet to push the piston 3 and move the piston rod 2, so that the piston rod 2 moves to the outside of the separator rod end 102 and the end cover 103. O-rings 5 ​​are provided on the inner and outer walls of the piston 3.

[0024] It should be noted that a wear-resistant ring is provided in the contact area between the opening and the piston rod 2; a protective sleeve 13 is provided on the separator rod outer sleeve 101, and the protective sleeve 13 is pressed on the separator rod outer sleeve 101 by a set screw, and the set screw passes through the separator rod outer sleeve 101 and presses on the separator rod end 102.

[0025] In this embodiment, as a further optimization, please refer to... Figure 1 A first elastic element 4 (such as a spring) is provided between the end 102 of the separating rod and the piston rod 2; the first elastic element 4 is used to pull the piston rod 2 and the piston 3 down to reset when the piston rod 2 stops moving upward.

[0026] In this embodiment, as a further optimization, please refer to... Figure 1 A thrust hook 10 is hinged to the end 102 of the separating rod via a pin. One end of the thrust hook 10 is in contact with the piston rod 2, and the other end is in contact with the medicine bag fixing rod 8, used to restrict the medicine bag fixing rod 8. A top head 11 is slidably provided on the end 102 of the separating rod. A second elastic element 12 (such as a spring) is provided between the top head 11 and the end 102 of the separating rod. The top head 11 is in contact with the end of the thrust hook 10 facing the medicine bag fixing rod 8, used to abut against the thrust hook 10. When gas enters the inner cavity of the outer sleeve 101 of the separating rod, the piston 3 and the piston rod 2 are pushed and moved. The step of the piston rod 2 abuts against the thrust hook 10 (the step divides the piston rod 2 into two areas with different diameters. The diameter of the area that initially contacts the thrust hook 10 is smaller than the diameter of the area that contacts the thrust hook 10 after crossing the step). Figure 1 Taking the direction as an example, the diameter of the left end of the piston rod 2 is smaller than that of the right end. The piston rod 2 continues to move upward, pushing the thrust hook 10 to rotate around the pin shaft and disengage from the medicine pack fixing rod 8. Then the end of the piston rod 2 passes through the opening and contacts the medicine pack fixing rod 8 (that is, the end of the piston rod 2 contacts the baffle of the medicine pack fixing rod 8), applying a lifting force to the medicine pack fixing rod 8, causing it to move away from the end 102 of the separating rod.

[0027] It should be noted that after the medicine pack fixing rod 8 is disengaged, the injection of air into the separation rod sleeve 101 is stopped, and the gas inside the separation rod sleeve 101 is discharged. At this time, the piston 3 loses the pressure provided by the gas, and the first elastic element 4 will reset and expand (the first elastic element 4 is compressed when the piston rod 2 lifts the medicine pack fixing rod 8), causing the piston rod 2 and piston 3 to move in opposite directions, completing the reset. When the piston rod 2 is driven by the first elastic element 4 to move into the separation rod sleeve 101, the diameter of the contact between the piston rod 2 and the thrust hook 10 decreases, reducing the compressive force on the thrust hook 10 and the pressure of the thrust hook 10 on the top head 11. The second elastic element 12 will reset and expand (the second elastic element 12 is compressed when the thrust hook 10 rotates around the pin and disengages from the medicine pack fixing rod 8), which is used to push the top head 11 to move and drive the thrust hook 10 to rotate in the opposite direction.

[0028] In this embodiment, as a further optimization, please refer to... Figure 1 A rolling rod 6 is provided at the end of the separating rod sleeve 101 away from the separating rod end 102. The separating rod sleeve 101 and the rolling rod 6 are connected by screws. A bottom cover 7 is provided on the rolling rod 6. The rolling rod 6 and the bottom cover 7 are connected by screws.

[0029] Example 2

[0030] As a further optimization of Embodiment 1, a mine chute dredging vehicle includes: a vehicle body, a chemical pack release assembly installed on the vehicle body, a gripper on the vehicle body that grips a rolling rod 6, and a rolling wheel on the gripper that rotates to drive the rolling rod 6 to move up or down to adjust the height of the support rod 1 and the chemical pack fixing rod 8.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
