[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] See also Figure 1 , Figure 2 and Figure 5 A device for clearing blockage in a mine chute comprises: a mobile device and a mechanical arm 1; the mechanical arm 1 is installed on the mobile device, and a fixing mechanism 2 is provided on the end of the mechanical arm 1.

[0031] The method of dredging the mine chute is as follows:

[0032] Step 1: Use a long-distance camera and a long-distance rangefinder to observe the internal situation of the chute, confirm the blockage position and height, and select a suitable length of the robot arm 1 according to the detection situation;

[0033] Step 2: After the explosive is fixed on the fixing mechanism 2, the moving device moves the mechanical arm 1 to the inside of the ore chute, and adjusts the angle of the mechanical arm 1 so that the explosive on the fixing mechanism 2 is close to the bottom of the blocked ore;

[0034] Step 3: Detonate explosives to clear the chute.

[0035] Example 2

[0036] As a further optimization scheme of Example 1, an adhesive (equivalent to glue) is applied to the upper surface of the explosive, and when the robotic arm 1 is moved to make the explosive on the fixing mechanism 2 contact the bottom of the blocked ore, the adhesive can be used to contact the bottom of the blocked ore, so that the explosive can be fixed to the bottom of the blocked ore, so that the fixing mechanism 2 can release the explosive, and the support and fixation of the robotic arm 1 and the fixing mechanism 2 are not required; then the robotic arm 1 and the fixing mechanism 2 can be removed from the chute, so that the robotic arm 1 and the fixing mechanism 2 can be removed during the detonation process, so that they can be reused, thereby reducing the cost of dredging.

[0037] It should be noted that the adhesive may also be replaced by an adhesive layer (similar to double-sided tape) or other fixing components, such as rock nails, rivets, etc., which can fix the explosives to block the bottom component of the ore.

[0038] It should also be noted that when using fixing components such as rock bolts and rivets (that is, external force is required to make them enter the rock), for example, hydraulic equipment is installed on the mechanical arm 1 to apply pressure to the fixing component.

[0039] Example 3

[0040] As a further optimization scheme of Example 1, the surface of the fixing mechanism 2 is coated with an adhesive (equivalent to glue), and the connection between the fixing mechanism 2 and the mechanical arm 1 can be disconnected; when the mechanical arm 1 is moved to make the explosive on the fixing mechanism 2 close to the bottom of the blocked ore, the fixing mechanism 2 is brought into contact with the bottom of the blocked ore, and the fixing mechanism 2 is fixed to the bottom of the blocked ore by utilizing the adhesive to contact the bottom of the blocked ore; then the connection between the fixing mechanism 2 and the mechanical arm 1 is disconnected, and the mechanical arm 1 is moved out of the chute, so that the mechanical arm 1 can be removed during the detonation process, so that it can be reused, thereby reducing the cost of dredging.

[0041] It should be noted that the adhesive may also be replaced by an adhesive layer (similar to double-sided tape) or other fixing components, such as rock nails, etc., which can fix the explosives to block the bottom component of the ore.

[0042] It should also be noted that when using fixing components such as rock bolts and rivets (that is, external force is required to make them enter the rock), hydraulic equipment is installed on the mechanical arm 1 to apply pressure to the fixing components.

[0043] Example 4

[0044] As a further optimized solution of Example 1, please refer to Figure 4 The robot arm 1 is a telescopic member, the fixing mechanism 2 is a gripper, and the gripper is installed on the moving end of the telescopic member.

[0045] It should be noted that the telescopic part can be made of PVC tube (that is, the telescopic part is composed of two or more PVC tubes, and one PVC tube is slidably inserted in another PVC tube), and rubber pads are installed at both ends of the telescopic part to seal the PVC tube; using PVC tube to make the telescopic part can reduce costs; and the telescopic part is connected to an air pump, which uses the air pump to supply air to the inside of the telescopic part to make it extend.

[0046] The method of dredging the mine chute is as follows:

[0047] Step 1: Use a long-distance camera and a long-distance rangefinder to observe the internal situation of the chute, confirm the blockage position and height, and select the appropriate length of the telescopic piece according to the detection situation;

[0048] Step 2: After grabbing the explosives with the gripper, the mobile device moves the telescopic member to the inside of the ore chute, and adjusts the angle of the telescopic member so that the explosives on the gripper are close to the bottom of the blocked ore by extending the telescopic member;

[0049] Step 3: Detonate explosives to clear the chute.

[0050] In this embodiment, as a further optimized solution, please refer to Figure 4 The surface of the explosive or the surface of the gripper is coated with adhesive (the adhesive can also be replaced by an adhesive layer or other fixing components, such as rock nails, which can fix the explosive to the bottom component of the blocked ore); when the telescopic member brings the explosive close to the bottom of the blocked ore, the explosive or the gripper is fixed to the bottom of the blocked ore using the adhesive or the fixing component, so that during the process of detonating the explosive, the telescopic member or the telescopic member and the gripper can be taken out of the chute, thereby reducing the cost of unblocking the chute.

[0051] Example 5

[0052] As a further optimized solution of Example 1, please refer to Figure 3The mechanical arm 1 is a telescopic member, and the fixing mechanism 2 includes a first pulley assembly 21 and a second pulley assembly 22 (the first pulley assembly 21 and the second pulley assembly 22 both include a mounting frame and a pulley rotatably mounted on the mounting frame). The first pulley assembly 21 is mounted on the fixed end of the telescopic member, and the second pulley assembly 22 is mounted on the movable end of the telescopic member. A pull rope is provided between the first pulley assembly 21 and the second pulley assembly 22, and the pull rope is placed on the pulley of the second pulley assembly 22. Both ends of the pull rope are on both sides of the second pulley assembly 22, and one end of the pull rope is tied with explosives, and the other end of the pull rope passes through the first pulley assembly 21 and extends to the outside of the chute. The first pulley assembly 21, the second pulley assembly 22 and the pull rope constitute a lifting assembly (pulling the pull rope, through the rotation of the first pulley assembly 21 and the second pulley assembly 22, can lift the explosive).

[0053] It should be noted that the first pulley assembly 21 installed on the fixed end of the telescopic member can be removed, that is, the fixing mechanism 2 can be composed solely of the second pulley assembly 22 and the pull rope.

[0054] The method of dredging the mine chute is as follows:

[0055] Step 1: Use a long-distance camera and a long-distance rangefinder to observe the internal situation of the chute, confirm the blockage position and height, and select the appropriate length of the telescopic piece according to the detection situation;

[0056] Step 2: After the explosive is tied to one end of the pull rope, the mobile device moves the telescopic member to the inside of the chute and adjusts the angle of the telescopic member. After the telescopic member is extended and the mobile end of the telescopic member is close to the bottom of the blocked ore, the telescopic member stops extending and then the pull rope is pulled to make the explosive rise close to the bottom of the blocked ore (after the staff fixes the pull rope and leaves the chute, the staff does not need to keep pulling the pull rope);

[0057] Step 3: Detonate explosives to clear the chute.

[0058] In this embodiment, as a further optimized solution, please refer to Figure 3 The second pulley assembly 22 is detachably mounted on the moving end of the telescopic member, and a fixing member 5 is provided on the second pulley assembly 22 (which may be an adhesive, or may be replaced by an adhesive layer or other fixing components, such as rock nails, etc., which can fix the explosive to the bottom component of the blocked ore), which is used to fix the second pulley assembly 22 to the bottom of the blocked ore, so that the explosive does not need to be supported by the telescopic member, and the telescopic member can be removed from the chute, which is used to reduce the cost of unblocking the chute.

[0059] It should be noted that the second pulley assembly 22 will stay in the chute; during the process of detonating the explosives, the operator is required to fix the pull rope, and then the staff will move out of the chute to ensure that the explosives are in the blasting area at the bottom of the blocked ore.

[0060] Example 6

[0061] As a further optimized solution of Example 4 or Example 5, please refer to Figure 2 The mobile device is a remote control car 4, a clamp 3 is hinged on the remote control car 4, an adjusting piece (such as an electric telescopic rod) is installed on the remote control car 4, the moving end of the electric telescopic rod is connected to the clamp 3 (for changing the angle of the clamp 3), and the clamp 3 clamps the telescopic piece.

[0062] See also Figure 8 , the method of dredging the chute mine is as follows:

[0063] Step 1: Use a long-distance camera and a long-distance rangefinder to observe the internal situation of the chute, confirm the blockage position and height, and select the telescopic parts of appropriate length;

[0064] Step 2: Move the remote control vehicle 4 into the moving channel of the mine chute, then use the clamp 3 to grasp the telescopic member, and use the fixing mechanism 2 to fix the explosives, and through the operation of the adjusting member, the clamp 3 is rotated to adjust the angle of the telescopic member so that the top of the telescopic member is lower than the lintel line;

[0065] Step 3: The remote control vehicle 4 moves forward, and at the same time adjusts the angle of the telescopic member so that the telescopic member is in an upright state after entering the ore chute;

[0066] Step 4: Slightly loosen the clamp 3 (the clamp 3 will not completely loosen the telescopic member, and the clamp 3 is used to limit the telescopic member so that it can only move up and down, but will not tilt or fall), so that the telescopic member falls and contacts the chute platform, and then the telescopic member extends until the top reaches the blocking position, so that the explosives are close to the bottom of the blocking ore;

[0067] Step 5: The clamp 3 releases the telescopic part, and the remote control vehicle 4 exits the chute;

[0068] Step 6: Remotely detonate explosives to clear the blockage in the mine shaft.

[0069] It should be noted that when the telescopic part is extended and the explosives are brought close to the area to be blasted, the top of the telescopic part or the fixing mechanism 2 contacts the bottom of the blocked ore to fix the telescopic part, so that after the clamp 3 completely releases the telescopic part, the telescopic part will not tilt or fall; during the above-mentioned work, the telescopic part remains inside the chute, therefore, the telescopic part can be made of PVC pipe (that is, the telescopic pipe is composed of two or more PVC pipes, and one PVC pipe is slidably inserted in another PVC pipe), and rubber pads are installed at both ends of the telescopic part for sealing the PVC pipe; using PVC pipe to make the telescopic part can reduce costs; and the telescopic part is connected to the air pump (the air pump is on the outside of the chute), and the air pump is used to supply air to the inside of the telescopic part to make it extend; and the fixing mechanism 2 is directly connected to the telescopic part, and the connection between the two does not need to be disconnected.

[0070] It should also be noted that when the fixing mechanism 2 is a grab, after the clamp 3 clamps the telescopic part, the explosive is directly fixed to the grab; when the fixing mechanism 2 is the first pulley assembly 21, the second pulley assembly 22 and the pull rope, after the clamp 3 clamps the telescopic part, the explosive is tied to one end of the pull rope, and after the telescopic part is extended, the pull rope is pulled to make the explosive rise to the blasting area, and then the staff fixes the pull rope, leaves the chute, and then detonates the explosive.

[0071] In this embodiment, as a further optimized solution, the fixing mechanism 2 is detachably connected to the movable end of the telescopic member.

[0072] See also Fig. 9 , the method of dredging the chute mine is as follows:

[0073] Step 1: Use a long-distance camera and a long-distance rangefinder to observe the internal situation of the chute, confirm the blockage position and height, and select the telescopic parts of appropriate length;

[0074] Step 2: Fix the explosive using the fixing mechanism 2, and apply adhesive or install other fixing components on the surface of the explosive or the fixing mechanism 2;

[0075] Step 3: Move the remote control car 4 into the moving channel of the mine chute, then use the clamp 3 to grasp the telescopic member, and through the adjustment member, rotate the clamp 3 to adjust the angle of the telescopic member so that the top of the telescopic member is lower than the lintel;

[0076] Step 4: The remote control vehicle 4 moves forward, and at the same time adjusts the angle of the telescopic member so that the telescopic member is in an upright state when entering the interior of the chute;

[0077] Step 5: Slightly loosen the clamp 3 (the clamp 3 will not completely loosen the telescopic part, and the clamp 3 limits the telescopic part so that it can only move up and down, but will not tilt or fall), and after the telescopic part falls and contacts the ore chute platform, the clamp 3 re-clamps the telescopic part, and the telescopic part stretches until the top reaches the blocking position, and the adhesive or other fixing components are connected to the bottom of the blocking ore, and the explosive or fixing mechanism 2 is fixed to the bottom of the blocking ore;

[0078] Step 6: After the fixing mechanism 2 releases the explosive or disconnects the telescopic member from the fixing mechanism 2, the telescopic member contracts, and the adjusting member works to rotate the clamp 3 to adjust the angle of the telescopic member so that the top of the telescopic member is lower than the lintel, and the remote control vehicle 4 exits the chute;

[0079] Step 7: Remotely detonate explosives to clear the blockage in the mine chute.

[0080] It should be noted that when the fixing mechanism 2 is a gripper, after the clamp 3 clamps the telescopic member, the explosive is directly fixed to the gripper; and when the fixing mechanism 2 is a gripper, there are two ways to fix the explosive. First, the gripper releases the explosive and can directly fix the explosive to the bottom of the blocked ore (adhesive or other fixing components are set on the explosive); second, disconnect the telescopic member from the gripper and fix the gripper to the bottom of the blocked ore to fix the explosive (adhesive or other fixing components are set on the gripper); when the fixing mechanism 2 is the first pulley assembly 21, the second pulley assembly 22 and the pull rope After the clamp 3 clamps the telescopic part, the explosive is tied to one end of the pull rope. After the telescopic part is extended, the pull rope is pulled to make the explosive rise to the blasting area and then detonate the explosive; and the operator pulls the pull rope on the outside of the chute; and the fixing mechanism 2 is a first pulley assembly 21, a second pulley assembly 22 and a pull rope, and the second pulley assembly 22 is detachably connected to the moving end of the telescopic part, by disconnecting the second pulley assembly 22 from the moving end of the telescopic part and fixing the second pulley assembly 22 to the bottom of the blocked ore (adhesive or other fixing components are set on the second pulley assembly 22).

[0088] Step 4: The prying machine 6 adjusts the angle of its own working arm so that the gripper grabs the explosive and reaches the ore blocking position, and fixes the explosive at the bottom of the blocked ore by using adhesive or installing other fixing components, then the gripper releases the explosive, and the prying machine 6 adjusts the angle of its own working arm so that the mechanical arm 1 is lower than the lintel height, and then the prying machine 6 exits the working area;

[0089] Step 5: Detonate explosives at a remote distance to clear the blockage in the mine chute.

[0090] It should be noted that in the fourth step, after the explosives are fixed, the internal situation of the chute is observed through a long-distance camera and a long-distance rangefinder to ensure that the explosives are fixed in the blocking position.
