[0002] This invention relates to the field of mine blasting technology, and in particular to a blasting pipe fixing mechanism and method for deep-hole blasting in mines. Background Technology

[0003] In deep-hole blasting in coal mines, when the top wall of the mine needs to be blasted, the bottom of the blast hole is at the top and the opening is at the bottom. After the explosive is installed in the blast hole, it is necessary to manually or mechanically support the explosive at the opening of the blast hole to prevent it from slipping out of the vertical blast hole. This will consume a lot of manpower and material resources. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a blasting pipe fixing mechanism for deep-hole blasting in mines. This mechanism can fix the blasting pipe at any position within the blasting hole to meet blasting needs, improve blasting accuracy, and eliminate the need for manual labor or other structures to support the blasting pipe at the hole opening, thereby saving manpower and material resources.

[0005] The present invention also proposes a method for fixing the blasting tube in deep-hole blasting of a mine, which has the aforementioned blasting tube fixing mechanism.

[0006] According to a first aspect of the present invention, a blasting tube fixing mechanism for deep-hole blasting in mines includes a blasting tube capable of storing explosives, a blasting hole bottom located above the blasting hole opening, and a blasting tube adapted to move toward the bottom of the blasting hole. The blasting tube fixing mechanism comprises a fixing component and a triggering component. The fixing component includes a connector and a fixing member. The connector is connected to one end of the blasting tube, and the fixing member is rotatably disposed on the connector between an initial position and a fixed position. The triggering component includes a triggering member disposed on the connector. When the triggering member is triggered, the fixing member can be rotated to a fixed position to fix the blasting tube inside the blasting hole.

[0007] According to an embodiment of the present invention, the blasting tube fixing mechanism for deep-hole blasting in mines, when the blasting material is conveyed upward (towards the bottom of the blasting hole), after moving to a predetermined position, triggers a triggering element to rotate the fixing element to a fixed position, thereby fixing the blasting tube inside the blasting hole. Furthermore, after the driving force of the driving mechanism is removed, the blasting tube will not slide towards the opening of the blasting hole, thus eliminating the need for manpower or other structures to support the blasting tube at the opening of the blasting hole, thereby saving manpower and material resources.

[0008] In addition, the blasting pipe fixing mechanism for deep-hole blasting in mines according to the present invention may also have the following additional technical features:

[0009] In some embodiments of the present invention, the connector is sleeved outside the trigger, the trigger is slidable relative to the connector, and the trigger protrudes from the end of the connector away from the blasting tube; wherein, when one end of the trigger abuts against the bottom of the blasting hole, the trigger slides downward and is triggered.

[0010] Optionally, the triggering component further includes a first support member having a folded position and an unfolded position. The other end of the trigger member is pivotally connected to the first support member. When the trigger member is triggered, the first support member rotates from the folded position to the unfolded position and drives the fixing member to rotate to the fixed position.

[0011] Furthermore, the triggering component also includes a first elastic member disposed between the first support member and the connecting member, the first elastic member being used to drive the first support member to move toward the unfolded position.

[0012] In some embodiments of the present invention, the trigger is arranged along the outer circumference of the connector, and after the driving force on the rupture tube is removed, the trigger moves downward and is triggered.

[0013] Optionally, the triggering component further includes a second support member rotatably connected to the fixing member, and the second support member is located on the side of the fixing member facing the rupture tube. After the triggering member is triggered, the second support member rotates and drives the fixing member to rotate to a fixed position.

[0014] Furthermore, the triggering component also includes a locking member for securing the second support member, one end of which is pivotally mounted on the fixing member; wherein, when the locking member secures the second support member, the other end of the locking member is adjacent to and below the triggering member, triggering the triggering member to unlock the second support member.

[0015] In some embodiments, a second elastic member is further included, which is disposed between the fixing member and the connecting member. When the blasting tube is driven to move toward the bottom of the blasting hole, the end of the fixing member away from the connecting member abuts against the wall of the blasting hole.

[0016] The present invention also proposes a method for fixing blasting pipes in deep-hole blasting in mines, which has the above-described embodiments.

[0017] According to a second aspect of the present invention, a method for fixing a blasting tube in deep-hole blasting in a mine, the blasting tube can store explosives, the bottom of the blasting hole is located above the opening of the blasting hole, and the blasting tube is adapted to move toward the bottom of the blasting hole. The method for fixing the blasting tube includes: driving the blasting tube to move toward the bottom of the blasting hole; after the blasting tube moves to a predetermined position, reducing the driving force on the blasting tube to trigger a triggering element; and driving a fixing element to rotate from an initial position to a fixed position to fix the blasting tube inside the blasting hole.

[0018] According to the method for fixing the blasting tube according to an embodiment of the present invention, during the upward movement of the blasting tube, after the triggering member is activated, the fixing member can rotate from the initial position to the fixed position to fix the blasting tube inside the blast hole, thereby enabling the blasting tube to blast at a predetermined position in the blast hole, thus improving the blasting accuracy. When the blasting tube is driven to move within the blast hole, the fixing member is in the initial position so that the fixing member does not obstruct the movement of the blasting tube within the blast hole.

[0019] In some embodiments, when the blasting tube moves to the bottom of the blast hole, the triggering element abuts against the bottom of the blast hole to trigger the triggering element; or, when the blasting tube moves to the calibrated position of the blast hole, the driving force on the blasting tube is removed, causing the blasting tube and the triggering element to move downward to trigger the triggering element.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 invention based on the specific circumstances.

[0036] The following is for reference. Figures 1-6 A blasting pipe fixing mechanism 100 for deep-hole blasting in mines according to an embodiment of the present invention is described.

[0037] like Figures 1-6 As shown, the blasting tube fixing mechanism 100 for deep-hole blasting in mines according to an embodiment of the present invention includes a blasting tube 200 for storing explosives. The bottom of the blasting hole is located above the opening of the blasting hole, and the blasting tube 200 is adapted to move towards the bottom of the blasting hole. In this embodiment, when installing the blasting tube 200 in the blasting hole, one end of the blasting tube 200 needs to be inserted into the blasting hole, and the other end of the blasting tube 200 can be connected to a driving mechanism. The driving mechanism can drive the blasting tube 200 to move, so that the blasting tube 200 gradually moves into the blasting hole. Furthermore, the blasting in this application is for vertically upward blasting holes, that is, the opening of the blasting hole is at the bottom and the bottom of the blasting hole is at the top, and the blasting tube 200 needs to move upward to reach the bottom of the blasting hole.

[0038] Combination Figure 4 As shown, the rupture tube fixing mechanism 100 includes: a fixing component 1 and a triggering component 2.

[0039] Specifically, the fixing component 1 includes a connector 11 and a fixing member 12. The connector 11 is connected to one end of the rupture tube 200, and the fixing member 12 is rotatably mounted on the connector 11 between an initial position and a fixed position. Figure 1 As shown, one end of the blasting tube 200 is connected to the connector 11, and the other end of the blasting tube 200 is connected to the driving mechanism (not shown in the figure). When the driving mechanism drives the blasting tube 200 to move towards the bottom of the blast hole ( Figure 1 As shown above, the connector 11 moves together with the blasting tube 200 towards the bottom of the blast hole, and when inside the blast hole, the connector 11 is located above the blasting tube 200. A fixing member 12 is provided on the connector 11 and is rotatable. When the blasting tube 200 moves inside the blast hole, the fixing member 12 is in its initial position. After the blasting tube 200 moves to a predetermined position inside the blast hole, the fixing member 12 can rotate from its initial position to a fixed position. The fixing member 12 in the fixed position can fix the blasting tube 200 inside the blast hole to prevent the blasting tube 200 from sliding downwards.

[0040] In some embodiments, the triggering component 2 includes a triggering element 21 disposed on the connector 11. When the triggering element 21 is triggered, the fixing element 12 can be rotated to a fixed position to fix the rupture tube 200 inside the rupture hole. See also... Figure 2 As shown, the trigger 21 is located at the end of the connector 11 away from the rupture tube 200. The trigger 21 is linked with the fixing member 12. When the trigger 21 is triggered, the fixing member 12 can rotate from the initial position to the fixed position. After the fixing member 12 rotates to the fixed position, the fixing member 12 squeezes or inserts a part of the fixing member 12 into the wall of the rupture hole, so that the fixing member 12 can fix the connector 11 and the rupture tube 200 in the rupture hole. When the driving force of the driving mechanism is removed, the rupture tube 200 will not slide downward under its own weight. This can save manpower or other structures to support the rupture tube 200 at the opening of the rupture hole, thereby saving manpower and material resources.

[0041] Understandably, once the blasting tube 200 moves to a predetermined position within the blast hole, the triggering element 21 can be activated, causing the fixing element 12 to secure the blasting tube 200 at the predetermined position. The predetermined position can be any location between the bottom and the opening of the blast hole, or it can be at the bottom of the blast hole itself; it can be set according to actual needs, and no specific restrictions are imposed here.

[0042] When the drive mechanism moves the rupture tube 200 within the rupture hole, the fixing member 12 is in its initial position so that it does not obstruct the movement of the rupture tube 200 within the rupture hole. When the fixing member 12 rotates to the fixed position, a portion of the fixing member 12 inserts into the wall of the rupture hole, or the fixing member 12 presses against the rupture hole, so that the fixing member 12 can fix the rupture tube 200 within the rupture hole.

[0043] According to an embodiment of the present invention, the blasting tube fixing mechanism 100 for deep hole blasting in mines, when the blasting tube is conveyed upward (towards the bottom of the blasting hole), after moving to a predetermined position, triggers the trigger member 21 to rotate the fixing member 12 to a fixed position, thereby fixing the blasting tube 200 in the blasting hole. Furthermore, after the driving force of the driving mechanism is removed, the blasting tube 200 will not slide towards the opening of the blasting hole, thus eliminating the need for manpower or other structures to support the blasting tube 200 at the opening of the blasting hole, thereby saving manpower and material resources.

[0044] In some embodiments of the present invention, the connector 11 is sleeved outside the trigger 21, the trigger 21 can slide relative to the connector 11, and the trigger 21 protrudes from the end of the connector 11 away from the blasting tube 200. When one end of the trigger 21 abuts against the bottom of the blasting hole, the trigger 21 slides downward and is triggered.

[0045] For example Figure 2As shown, the connector 11 can be a hollow structure, with the trigger 21 located inside the connector 11, and the trigger 21 can slide up and down relative to the connector 11. At the end of the connector 11 away from the blasting tube 200, the trigger 21 protrudes from the connector 11, that is, at least a portion of the trigger 21 extends out of the connector 11 away from the blasting tube 200. Thus, when the drive mechanism drives the blasting tube 200 to move towards the bottom of the blasting hole located at the top, a portion of the trigger 21 is located above the connector 11, and the trigger 21 contacts and presses against the bottom of the blasting hole before the connector 11. When the trigger 21 presses against the bottom of the blasting hole, the trigger 21 slides downward and retracts into the connector 11, thereby triggering the trigger 21.

[0046] Optionally, the triggering component 2 further includes a first support member 22 having a folded position and an unfolded position. The other end of the triggering member 21 is pivotally connected to the first support member 22. After the triggering member 21 is triggered, the first support member 22 rotates from the folded position to the unfolded position and drives the fixing member 12 to rotate to the fixed position.

[0047] When trigger 21 is not triggered, see [link / reference] Figure 2 As shown, one end of the first support member 22 extends toward one end of the trigger member 21, and the other end of the first support member 22 is connected to the other end of the trigger member 21 and is located inside the connector 11. The connector 11 can limit one end of the first support member 22 so that the first support member 22 is in the retracted position and in the retracted state.

[0048] When trigger 21 is triggered, refer to Figure 3 As shown, the trigger 21 moves downward, and the trigger 21 moves downward and drives the first support 22 to move downward, so that one end of the first support 22 is released from the restriction of the connector 11, thereby causing the first support 22 to rotate relative to the connector 11 and the trigger 21, that is, the first support 22 moves from the folded position to the unfolded position.

[0049] During the process of the first support member 22 rotating to the deployed position, the first support member 22 abuts against the fixing member 12 and drives the fixing member 12 to rotate to the fixed position. When the first support member 22 rotates to the deployed position, the fixing member 12 rotates to the fixed position, thereby enabling the first support member 22 to support the fixing member 12 and keep it in the fixed position, and also enabling the fixing member 12 to stably fix the rupture tube 200. It is understood that there can be multiple first support members 22, and there is no limitation on the number of first support members 22.

[0050] Furthermore, the triggering component 2 also includes a first elastic element 23 disposed between the first support member 22 and the connecting member 11. The first elastic element 23 is used to drive the first support member 22 to move toward the unfolded position. When the first support member 22 is in the retracted position, the first elastic element 23 is in a compressed state. When the triggering member 21 is triggered, the connecting member 11 no longer restricts the first support member 22, and the first elastic element 23 releases energy to drive the first support member 22 to rotate and move to the unfolded position.

[0051] In some embodiments of the present invention, the trigger 21 is disposed along the outer periphery of the connector 11. After the driving force on the rupture tube 200 is removed, the trigger 21 moves downward and is triggered. See also Figure 4 As shown, the trigger 21 is located outside the connector 11 and is arranged along the circumference of the connector 11. When the driving mechanism removes the upward driving force on the rupture tube 200, the rupture tube 200 and the connector 11 move downward, thereby causing the trigger 21 on the connector 11 to also move downward. After the trigger 21 moves downward, the trigger 21 is triggered and causes the fixing member 12 to rotate toward a fixed position.

[0052] Optionally, the triggering component 2 further includes a second support 24 rotatably connected to the fixing member 12, and the second support 24 is located on the side of the fixing member 12 facing the rupture tube 200. After the triggering member 21 is triggered, the second support 24 rotates and drives the fixing member 12 to rotate to a fixed position.

[0053] See Figure 4 and Figure 5 As shown, one end of the second support member 24 is rotatably connected to the fixing member 12, and the other end of the second support member 24 extends toward the connecting member 11. When the trigger member 21 is triggered to move downward, the trigger member 21 touches the other end of the second support member 24, causing the second support member 24 to rotate. The direction of rotation of the second support member 24 can be found in [reference needed]. Figure 6 The arrows indicate the direction of the movement. When the other end of the second support member 24 abuts against the connector 11, the second support member 24 can drive the fixing member 12 to rotate to a fixed position and support the fixing member 12 to remain in the fixed position. When the other end of the second support member 24 abuts against the connector 11, the second support member 24, the connector 11, and the fixing member 12 together form a triangle, thereby ensuring that the fixing member 12 can stably fix the blasting tube 200 within the blasting hole.

[0054] Furthermore, the trigger assembly 2 also includes a locking member 25 for locking the second support member 24, one end of which is pivotally disposed on the fixing member 12; wherein, when the locking member 25 locks the second support member 24, the other end of the locking member 25 is adjacent to the trigger member 21 and located below the trigger member 21, triggering the trigger member 21 to unlock the second support member 24.

[0055] In other words, when the trigger 21 moves downward, the trigger 21 can touch the locking member 25, so that the locking member 25 unlocks the second support member 24. After the second support member 24 is unlocked, the second support member 24 rotates and drives the fixing member 12 to rotate toward the fixed position, thereby achieving fixed support for the rupture tube 200.

[0056] When the locking member 25 is in the state of locking the second support member 24, the locking member 25 can limit the second support member 24 so that the second support member 24 is attached to the fixing member 12. When the locking member 25 is unlocked, one end of the locking member 25 rotates relative to the fixing member 12, so that the locking member 25 no longer limits the second support member 24, thereby allowing the second support member 24 to rotate.

[0057] In one example, a torsion spring is provided between the second support member 24 and the fixing member 12. When the locking member 25 locks the second support member 24, the torsion spring is in an energy storage state. When the locking member 25 unlocks, the torsion spring releases energy to drive the second support member 24 to rotate in the direction of the connecting member 11.

[0058] In some embodiments of the present invention, the blasting pipe fixing mechanism 100 for deep hole blasting in mines further includes a second elastic member 26, which is disposed between the fixing member 12 and the connecting member 11. When the blasting pipe 200 is driven to move toward the bottom of the blasting hole, the end of the fixing member 12 away from the connecting member 11 abuts against the wall of the blasting hole.

[0059] Please see Figure 4 As shown, the second elastic member 26 supports the fixing member 12 and can keep the fixing member 12 in contact with the wall of the blast hole. When the driving mechanism removes the driving force on the blast tube 200, the fixing member 12 rotates at a certain angle relative to the connecting member 11 to prevent the blast tube 200 from falling directly to the blast hole opening after the driving force is removed. At the same time, the trigger member 21 is triggered, and the fixing member 12 rotates toward the fixed position to support and fix the blast tube 200.

[0060] The present invention also proposes a method for fixing the blasting tube 200 in deep-hole blasting of mines using a blasting tube fixing mechanism 100 having the above-described embodiments.

[0061] According to a second aspect embodiment of the present invention, the blasting tube 200 can store explosives. The bottom of the blast hole is located above the opening of the blast hole. The blasting tube 200 is adapted to move towards the bottom of the blast hole. In an embodiment of the present invention, when the blasting tube 200 is installed in the blast hole, one end of the blasting tube 200 needs to be inserted into the blast hole, and the other end of the blasting tube 200 can be connected to a driving mechanism. The driving mechanism can drive the blasting tube 200 to move, so that the blasting tube 200 gradually moves into the blast hole. In addition, the blasting in this application is aimed at a vertically upward blast hole, that is, the opening of the blast hole is below and the bottom of the blast hole is above. The blasting tube 200 needs to move upward to reach the bottom of the blast hole.

[0062] The method for fixing the blasting tube 200 includes: driving the blasting tube 200 to move towards the bottom of the blast hole; after the blasting tube 200 moves to a predetermined position, reducing the driving force on the blasting tube 200 so that the trigger 21 is triggered; driving the fixing member 12 to rotate from the initial position to the fixed position so as to fix the blasting tube 200 in the blast hole.

[0063] The drive mechanism is connected to the blasting tube 200 and drives the blasting tube 200 to move toward the bottom of the blast hole. When the blasting tube 200 moves to a predetermined position in the blast hole, the trigger 21 is triggered to make the fixing member 12, which is located in the initial position, rotate toward the fixed position. When the fixing member 12 rotates to the fixed position, the fixing member 12 can fix the blasting tube 200 at the predetermined position in the blast hole.

[0064] It is understood that when the driving mechanism removes the driving force on the blasting tube 200, the driving force can be gradually reduced until it is zero. This ensures that when the fixing member 12 rotates to the fixed position, the blasting tube 200 will not fall directly from the blasting hole to the blasting hole opening under the action of gravity.

[0065] According to the method for fixing the blasting tube 200 according to an embodiment of the present invention, during the upward movement of the blasting tube 200, after the trigger member 21 is triggered, the fixing member 12 can rotate from the initial position to the fixed position to fix the blasting tube 200 in the blast hole, thereby enabling the blasting tube 200 to blast at a predetermined position in the blast hole, thus improving the blasting accuracy. When the blasting tube 200 is driven to move in the blast hole, the fixing member 12 is in the initial position so that the fixing member 12 does not obstruct the movement of the blasting tube 200 in the blast hole.

[0066] In some embodiments of the present invention, when the blasting tube 200 moves to the bottom of the blast hole, the trigger 21 abuts against the bottom of the blast hole to trigger the trigger 21; or, when the blasting tube 200 moves to the marked position of the blast hole, the driving force on the blasting tube 200 is removed, causing the blasting tube 200 and the trigger 21 to move downward to trigger the trigger 21.

[0067] In other words, in this application, there are two ways to trigger the trigger 21. One triggering method is that the blasting tube 200 needs to move to the bottom of the blast hole, and the bottom of the blast hole triggers the trigger 21. The other triggering method is that when the blasting tube 200 is in the marked position in the blast hole, the driving force on the blasting tube 200 is gradually reduced, so that the blasting tube 200 and the connecting member 11 tend to move downward, or the blasting tube 200 and the connecting member 11 gradually move downward, thereby causing the trigger 21 to move downward, and thus triggering the trigger 21. After the trigger 21 moves downward, the trigger 21 can unlock the fixing member 12, so that the fixing member 12 rotates towards a fixed position.
