A burst tube fixing mechanism 100 for deep hole blasting in a mine according to an embodiment of the present invention will be described with reference to fig. 1 to 6.
As shown in fig. 1 to 6, according to the tube fixing mechanism 100 for deep hole blasting in a mine, a tube 200 can store explosives, the bottom of a hole is located above the hole opening of a blast hole, and the tube 200 is suitable for moving towards the bottom of the hole. In the embodiment of the present invention, when the blasting tube 200 is installed in the blasting hole, one end of the blasting tube 200 is inserted into the blasting hole, and the other end of the blasting tube 200 may be connected to a driving mechanism, which can drive the blasting tube 200 to move, so that the blasting tube 200 gradually moves into the blasting hole. In addition, the blasting of this application is to vertical ascending blast hole, and the blast hole drill way is down promptly, and the blast tube 200 needs upwards activity in order to move about to the blast hole bottom at the upper portion of blast hole.
As shown in fig. 4, the fastening mechanism 100 for the blast tube 200 includes: a fixed component 1 and a trigger component 2.
Specifically, the fixing assembly 1 comprises: a connecting member 11 and a fixing member 12, the connecting member 11 being connected to one end of the blasting tube 200, the fixing member 12 being rotatably provided on the connecting member 11 between an initial position and a fixing position. Referring to fig. 1, one end of the blast tube 200 is connected to the connecting member 11, and the other end of the blast tube 200 is connected to the driving mechanism (not shown), so that when the driving mechanism drives the blast tube 200 to move toward the bottom of the blast hole (upward in fig. 1), the connecting member 11 moves together with the blast tube 200 toward the bottom of the blast hole, and the connecting member 11 is located above the blast tube 200 when inside the blast hole. The fixing piece 12 is arranged on the connecting piece 11, the fixing piece 12 can rotate, when the blasting tube 200 moves in the blasting hole, the fixing piece 12 is in an initial position, after the blasting tube 200 moves to a predetermined position in the blasting tube 200, the fixing piece 12 can rotate to a fixed position from the initial position, and the rotating piece located at the fixed position can fix the blasting tube 200 in the blasting hole so as to prevent the blasting tube 200 from sliding downwards.
In some embodiments, the trigger assembly 2 includes a trigger member 21 disposed on the connector 11, and when the trigger member 21 is triggered, the securing member 12 is rotated to a securing position to secure the detonator 200 within the blast hole. Referring to fig. 2, the trigger 21 is disposed at an end of the connecting member 11 away from the blasting tube 200, the trigger 21 is linked with the fixing member 12, and when the trigger 21 is triggered, the fixing member 12 can rotate from an initial position to a fixed position. After the fixed part 12 rotates to the fixed position, the fixed part 12 extrudees or the part of fixed part 12 inserts to the blast hole pore wall to make fixed part 12 can fix connecting piece 11 and blast tube 200 in the blast hole, after removing actuating mechanism's drive power, blast tube 200 can not slide downwards under the dead weight effect, so can save manpower or other structures and support blast tube 200 in the drill way department in blast hole, thereby can use manpower sparingly and material resources.
It will be appreciated that after the tube 200 has been moved to a predetermined position within the blasthole, the trigger 21 can be activated to cause the anchor 12 to secure the tube 200 in the predetermined position. The preset position can be any position between the bottom of the blast hole and the orifice of the blast hole, and also can be the bottom of the blast hole, and can be set according to actual needs, and the preset position is not particularly limited.
When the drive mechanism drives the burst tube 200 to move within the burst hole, the anchor 12 is in an initial position so that the anchor 12 does not impede the movement of the burst tube 200 within the burst hole. When the fixing member 12 is rotated to the fixing position, a portion of the fixing member 12 is inserted into the wall of the blast hole, or the fixing member 12 presses the blast hole, so that the fixing member 12 can fix the squib 200 in the blast hole.
According to the fixing mechanism 100 for the blasting tube of the mine deep hole blasting, when the conveying blasting moves upwards (towards the bottom of the blasting hole), after the conveying blasting moves to the preset position, the trigger piece 21 is triggered to enable the fixing piece 12 to rotate to the fixed position, so that the fixing piece 12 can fix the blasting tube 200 in the blasting hole, and after the driving force of the driving mechanism is removed, the blasting tube 200 cannot slide towards the direction of the hole opening of the blasting hole, so that the phenomenon that the blasting tube 200 is supported by manpower or other structures at the hole opening of the blasting hole can be omitted, and further, the manpower and material resources can be saved.
In some embodiments of the present invention, the connecting member 11 is sleeved outside the triggering member 21, the triggering member 21 is slidable relative to the connecting member 11, and the triggering member 21 protrudes from an end of the connecting member 11 away from the blast tube 200, wherein when the end of the triggering member 21 abuts against the bottom of the blast hole, the triggering member 21 slides downward and is triggered.
For example, as shown in fig. 2, the connecting member 11 may have a hollow structure, the triggering member 21 is located inside the connecting member 11, and the triggering member 21 can slide up and down relative to the connecting member 11. At the end of the attachment 11 remote from the blasting tube 200, the triggering member 21 protrudes from the attachment 11, i.e. at least part of the triggering member 21 protrudes from the end of the attachment 11 remote from the blasting tube 200. Thus, when the driving mechanism drives the blast tube 200 to move toward the bottom of the blast hole located at the top, a part of the trigger 21 is located above the connecting member 11, and the trigger 21 contacts and presses the bottom of the blast hole before the connecting member 11, and when the trigger 21 presses the bottom of the blast hole, the trigger 21 slides downward and retracts into the connecting member 11, so that the trigger 21 is triggered.
Optionally, the triggering assembly 2 further includes a first supporting member 22 having a folded position and an unfolded position, the other end of the triggering member 21 is pivotally connected to the first supporting member 22, and after the triggering member 21 is triggered, the first supporting member 22 rotates from the folded position to the unfolded position and drives the fixing member 12 to rotate to the fixed position.
When the trigger 21 is not triggered, referring to fig. 2, one end of the first supporting member 22 extends toward one end of the trigger 21, the other end of the first supporting member 22 is connected to the other end of the trigger 21 and is located in the connecting member 11, and the connecting member 11 can limit one end of the first supporting member 22, so that the first supporting member 22 is located at the folded position and in the folded state.
When the trigger 21 is triggered, referring to fig. 3, the trigger 21 moves downward and drives the first supporting member 22 to move downward, so that one end of the first supporting member 22 is separated from the limit of the connecting member 11, and the first supporting member 22 rotates relative to the connecting member 11 and the trigger 21, i.e. the first supporting member 22 rotates from the folded position to the unfolded position.
During the rotation of the first support 22 to the deployed position, the first support 22 abuts the fixed member 12 and drives the fixed member 12 to rotate to the fixed position. When the first support 22 is rotated to the deployed position, the fixing member 12 is rotated to the fixing position, so that the first support 22 can support the fixing member 12 to be maintained at the fixing position, and also the fixing member 12 can stably fix the blasting tube 200. It is understood that the first support 22 may be plural, and the number of the first supports 22 is not limited herein.
Further, the triggering assembly 2 further comprises a first elastic member 23 disposed between the first supporting member 22 and the connecting member 11, wherein the first elastic member 23 is used for driving the first supporting member 22 to move toward the unfolding position. When the first supporting member 22 is located at the folded position, the first elastic member 23 is in a compressed state, and when the triggering member 21 is triggered, the connecting member 11 no longer restricts the first supporting member 22, and the first elastic member 23 releases energy to drive the first supporting member 22 to rotate and move to the unfolded position.
In some embodiments of the present invention, the triggering member 21 is disposed along the outer circumference of the connecting member 11, and after the driving force to the explosion tube 200 is removed, the triggering member 21 moves downward and is triggered. Referring to fig. 4, the trigger 21 is located outside the connecting member 11 and is disposed along the circumferential direction of the connecting member 11, when the driving mechanism removes the upward driving force to the blasting tube 200, the blasting tube 200 and the connecting member 11 move downward, so that the trigger 21 disposed on the connecting member 11 also moves downward, and when the trigger 21 moves downward, the trigger 21 is triggered and the fixing member 12 rotates toward the fixing position.
Optionally, the triggering assembly 2 further comprises a second supporting member 24 rotatably connected to the fixing member 12, wherein the second supporting member 24 is located on a side of the fixing member 12 facing the blasting tube 200, and after the triggering member 21 is triggered, the second supporting member 24 rotates and drives the fixing member 12 to rotate to the fixed position.
Referring to fig. 4 and 5, one end of the second supporting member 24 is rotatably connected to the fixing member 12, and the other end of the second supporting member 24 extends toward the connecting member 11. When the trigger 21 is triggered to move downward, the trigger 21 touches the other end of the second support 24 to rotate the second support 24, and the direction of rotation of the second support 24 can be referred to the direction of the arrow marked in fig. 6. When the other end of the second supporting member 24 abuts against the connecting member 11, the second supporting member 24 can drive the fixing member 12 to rotate to the fixing position, and can support the fixing member 12 to be kept at the fixing position. When the other end of the second supporting member 24 abuts against the connecting member 11, the second supporting member 24, the connecting member 11 and the fixing member 12 form a triangle together, thereby ensuring that the fixing member 12 can stably fix the blasting tube 200 in the blasting hole.
Furthermore, the trigger assembly 2 further includes a locking member 25 for locking the second support 24, and one end of the locking member 25 is pivotally disposed on the fixing member 12; when the locking member 25 locks the second support 24, the other end of the locking member 25 is adjacent to the trigger 21 and below the trigger 21, and the trigger 21 is triggered to unlock the second support 24 from the locking member 25.
That is, when the trigger 21 is moved downward, the trigger 21 may touch the locking member 25, so that the locking member 25 unlocks the second support member 24, and 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 fixedly supporting the blasting tube 200.
When the locking member 25 is in a state of locking the second supporting member 24, the locking member can limit the position of the second supporting member 24, so that the second supporting member 24 is attached to the fixing member 12. When the locking member is unlocked, one end of the locking member rotates relative to the fixing member 12, so that the locking member no longer limits the second supporting member 24, and the second supporting member 24 rotates.
In one example, a torsion spring is disposed between the second support 24 and the fixing member 12, and when the locking member 25 locks the second support 24, the torsion spring is in an energy storage state, and when the locking member 25 is unlocked, the torsion spring releases energy to drive the second support 24 to rotate toward the connecting member 11.
In some embodiments of the present invention, the tube fixing mechanism 100 for deep hole blasting in a mine further comprises a second elastic member 26, the second elastic member 26 is disposed between the fixing member 12 and the connecting member 11, and when the tube 200 is driven to move toward the bottom of the hole, the end of the fixing member 12 away from the connecting member 11 abuts against the wall of the hole.
Referring to fig. 4, the second elastic member 26 supports the fixed member 12 to keep the fixed member 12 in contact with the wall of the blast hole, and when the driving mechanism removes the driving force applied to the blast tube 200, the fixed member 12 rotates at a certain angle relative to the connecting member 11 to prevent the blast tube 200 from directly falling to the opening of the blast hole after the driving force is removed, and at the same time, the trigger member 21 is triggered, and the fixed member 12 rotates toward the fixed position to support the fixed blast tube 200.
The invention also provides a method for fixing the blasting tube 200 for mine deep hole blasting, which is provided with the blasting tube fixing mechanism 100 for mine deep hole blasting of the embodiment.
In the embodiment of the present invention, when the blasting tube 200 is installed 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 may be connected to a driving mechanism capable of driving the blasting tube 200 to move, so that the blasting tube 200 gradually moves into the blasting hole. In addition, the blasting of this application is to vertical ascending blast hole, and the blast hole drill way is down promptly, and the blast tube 200 needs upwards activity in order to move about to the blast hole bottom at the upper portion of blast hole.
The method for fixing the blasting cartridge 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 to the blasting tube 200 to trigger the trigger piece 21; the fastener 12 is driven to rotate from the initial position to the securing position to secure the squib 200 within the squib.
The driving mechanism is connected with the blasting tube 200 and drives the blasting tube 200 to move towards the bottom of the blast hole, after the blasting tube 200 moves to a preset position in the blast hole, the triggering piece 21 is triggered to enable the fixing piece 12 located at the initial position to rotate towards the fixed position, and after the fixing piece 12 rotates to the fixed position, the fixing piece 12 can fix the blasting tube 200 at the preset position of the blast hole.
It can be understood that when the driving mechanism removes the driving force to the blasting tube 200, the driving force may be removed in a manner of gradually decreasing until the driving force is zero, so that the blasting tube 200 may not directly fall from the inside of the blast hole to the opening of the blast hole under the action of gravity in the process of rotating the fixing member 12 to the fixing position.
According to the method for fixing the blasting tube 200 of the embodiment of the invention, after the trigger 21 is triggered in the upward movement process of the blasting tube 200, the fixing member 12 can rotate from the initial position to the fixed position to fix the blasting tube 200 in the blasting hole, so that the blasting tube 200 can be blasted at the preset position of the blasting hole, and the blasting accuracy is further improved. When the detonator 200 is actuated to move within the blast hole, the securing member 12 is in an initial position such that the securing member 12 does not impede the movement of the detonator 200 within the blast hole.
In some embodiments of the present invention, when the squib 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 calibrated position of the blast hole, the driving force to the blasting tube 200 is removed, so that the blasting tube 200 and the trigger 21 move downwards to trigger the trigger 21.
That is, in the present application, there are two ways to trigger the trigger member 21, one of which is: the blast tube 200 needs to be moved to the bottom of the blast hole, which triggers the trigger 21. Another triggering method is as follows: when the blasting tube 200 is at a fixed position in the blast hole, the driving force for the blasting tube 200 is gradually reduced, so that the blasting tube 200 and the connecting piece 11 have a downward moving trend, or the blasting tube 200 and the connecting piece 11 gradually move downward, so that the trigger piece 21 moves downward, and the trigger piece 21 is triggered, and after the trigger piece 21 moves downward, the trigger piece 21 can unlock the fixing piece 12, so that the fixing piece 12 rotates toward a fixed position.
