Description

Technical Field

[0001] The invention belongs to the technical field of blasting, in particular to a detonator blasting device. Background Art

[0002] Detonators are the main explosive materials for blasting projects. Their function is to generate detonation energy to detonate various explosives, detonating cords, and booster tubes. Detonators are divided into two types: fire detonators and electric detonators. Electric detonators are used in coal mines. Electric detonators are divided into instantaneous electric detonators and delayed electric detonators. Delayed electric detonators are further divided into second-delay electric detonators and millisecond-delay electric detonators. The ignition devices of ammunition, explosive packs, etc. are generally made of pyrophoric chemicals such as fulminate of mercury in metal tubes.

[0003] In the prior art, when a detonator is installed in a blasthole, if the detonator itself has a fault, the explosive will not be detonated. In this case, the detonator in the blasthole needs to be taken out for replacement. In the process of taking out the detonator, the lead is directly dragged. On the one hand, it is easy to break the lead and cause the detonator to remain in the blasthole. On the other hand, if the side wall of the blasthole is touched during the dragging process, it may cause the blasthole to collapse. All of the above affect the detonation of the explosive. Moreover, if the detonator is filled with gun mud after being filled, taking out the detonator at this time is more likely to cause the above situation to occur.

[0004] In view of this, the present invention solves the above technical problems by proposing a detonator blasting device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem of conveniently taking out the detonator from the blast hole when the detonator fails, the present invention provides a detonator blasting device.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a detonator blasting device, including an extension mechanism and a clamping mechanism;

[0007] The extension mechanism is composed of a plurality of multi-stage telescopic rods, the telescopic rods are distributed in a ring to form a No. 1 interval, and the two ends of the telescopic rods are respectively fixedly connected to a No. 1 ring and a No. 2 ring, and the No. 1 ring is larger than the No. 2 ring;

[0008] The clamping mechanism consists of a clamping ring and a pull rod. The clamping ring is nested in the No. 1 interval, and the clamping ring contacts the portion of the telescopic rod close to the No. 1 interval. A pull rod is provided on one side of the clamping ring close to the No. 1 ring, and the pull rod passes through the No. 1 ring. The middle portion of the clamping ring clamps the detonator.

[0009] During operation, in a blasting project, it is necessary to insert a detonator into a blasthole. Before inserting the detonator into the blasthole, the detonator is first nested on the clamping ring, and the aperture of the middle part of the No. 1 ring and the No. 2 ring is equal to the diameter of the detonator, and the aperture of the blasthole is larger than the outer diameter of the No. 2 ring; the No. 2 ring is inserted into the blasthole, and the detonator does not extend out of the No. 2 ring at this time, so as to prevent the detonator from being damaged by collision during the forward movement of the extension mechanism. Subsequently, the multi-stage telescopic rod can be extended according to the depth of the blasthole, and pull rods of different lengths can also be selected according to the depth of the blasthole. In the process of the telescopic rod extending into the blasthole, this device can detect the depth of the blasthole. The hole depth can be prevented from collapsing and being blocked; when the telescopic rod is extended to the specified position, the telescopic rod is stopped from being extended, and the No. 2 ring is fixed to the entrance of the blasthole, and the pull rod is adjusted to make the detonator extend out of the No. 2 ring and contact the explosive; when the detonator is found to be faulty, the pull rod is pulled to make the clamping ring slide on the inner wall of the telescopic rod, which facilitates the removal of the detonator. In this process, it is effectively avoided that the detonator touches the hole wall, causing the blasthole to collapse and affecting the secondary filling; and the collapse of the blasthole is avoided, thereby avoiding the soil blocking the explosive, and avoiding the soil blocking the detonator and the explosive when the detonator is installed next time, affecting the detonation of the explosive.

[0010] Preferably, the pull rod is threadedly connected to rod No. 1, and the rod No. 1 is nested in the clamping ring. The other end of the rod No. 1 is rotatably connected to rod No. 3, and the angle between rod No. 1 and rod No. 3 is an acute angle; the other end of the rod No. 3 is rotatably connected to rod No. 2, and the rod No. 2 is nested in the clamping ring. Rod No. 1 and rod No. 2 are 90 degrees to each other, and a clamping block is fixed to the end of the rod No. 2 away from the inside of the clamping ring.

[0011] During operation, when a detonator failure is found and needs to be pulled out, if the hole is already filled with gun mud or the pulling resistance is large, the detonator is likely to fall off during the pulling process; therefore, when the pull rod is pulled, this setting causes the No. 1 rod to move toward the exit of the blast hole. Due to the connection between the No. 1 rod and the No. 3 rod and the limitation of the No. 2 rod by the clamping ring, combined with the motion knowledge of the four-bar mechanism, the No. 2 rod moves toward the middle part of the clamping ring, thereby pushing the clamping block to extend toward the central part of the clamping ring, thereby clamping the detonator, making it difficult for the detonator to fall off during the pulling process; and when the pull rod is pushed, the clamping block will also retract, so it will not affect the initial installation of the detonator.

[0012] Preferably, a groove is provided on a side of the clamping block away from the clamping ring.

[0013] During operation, a groove is provided on the side of the clamping block away from the clamping ring. This arrangement makes it possible for the clamping block to extend and contact the surface of the detonator. Due to the presence of the groove, the unevenness of the surface of the clamping block is increased, thereby hindering the relative movement between the detonator and the clamping block. This further ensures that the detonator is not easy to fall off during the pulling process, thereby ensuring the normal operation of the device.

[0014] Preferably, a ball bearing is provided at the contact portion between the clamping ring and the telescopic rod.

[0015] During operation, a ball bearing is provided at the contact portion between the clamping ring and the telescopic rod. When the clamping ring moves relative to the telescopic rod, this arrangement allows sliding friction between the clamping ring and the telescopic rod, making it easier for the clamping ring to move relative to the telescopic rod, making it easier for the clamping ring to be pulled out or pushed in; thereby making it more convenient to pull out and put in the detonator; and ensuring the normal function of the device.

[0016] Preferably, a plurality of arc-shaped hooks are evenly arranged on the surface of the telescopic rod away from the No. 1 section, and the hooks are bent toward the direction of the No. 1 ring.

[0017] When working, a plurality of arc-shaped hooks are evenly arranged on the surface of the telescopic rod away from the No. 1 interval, and the hooks are bent toward the direction of the No. 1 ring. When the telescopic rod enters the blast hole, there is little obstruction between the hooks and the side walls of the blast hole, making it easy for the telescopic rod to be placed in the blast hole. When the telescopic rod wants to move outward, the hooks will hook the side walls of the blast hole, making it difficult for the telescopic rod to move out, thereby ensuring the stability of the telescopic rod in the blast hole and making it difficult for the telescopic rod to be pulled out.

[0018] Preferably, the hook is rotatably connected to the telescopic rod.

[0019] During operation, the hook is rotatably connected to the telescopic rod. When the telescopic rod enters the blast hole, the hook rotates toward the blast hole exit, so that the obstruction of the blast hole to the hook is minimized, and it is further easier to put the telescopic rod into the blast hole. When the telescopic rod wants to move outward, the hook rotates away from the blast hole exit. This process causes the hook tip to scratch the side wall of the blast hole, further increasing the obstruction of the blast hole to the hook, and further making it difficult for the telescopic rod to move out, further ensuring the stability of the telescopic rod in the blast hole, and making it difficult for the telescopic rod to be pulled out.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The detonator blasting device described in the present invention facilitates the removal of the detonator by pulling the pull rod to make the clamping ring slide on the inner wall of the telescopic rod. In this process, it is effectively avoided that the detonator touches the hole wall, causing the blast hole to collapse and affecting the secondary filling; and the blast hole collapse is avoided, thereby avoiding the soil blocking the explosive, and avoiding the soil blocking the detonator and the explosive when the detonator is loaded next time, thereby affecting the detonation of the explosive.

[0022] 2. A detonator blasting device described in the present invention is characterized in that a plurality of arc-shaped hooks are evenly arranged on the surface of the telescopic rod away from the No. 1 interval, and the hooks are bent toward the direction of the No. 1 ring. When the telescopic rod enters the blast hole, there is little obstruction between the hooks and the side wall of the blast hole, making it easy to put the telescopic rod into the blast hole. When the telescopic rod wants to move outward, the hooks will hook the side wall of the blast hole, making it difficult for the telescopic rod to move out, thereby ensuring the stability of the telescopic rod in the blast hole and making it difficult for the telescopic rod to be pulled out.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 7 As shown, a detonator blasting device according to the present invention comprises an extension mechanism 1 and a clamping mechanism 2;

[0034] The extension mechanism 1 is composed of a plurality of multi-stage telescopic rods 11, wherein the telescopic rods 11 are distributed in a ring to form a first interval 12, and the two ends of the telescopic rods 11 are respectively fixedly connected with a first ring 13 and a second ring 14, and the first ring 13 is larger than the second ring 14;

[0035] The clamping mechanism 2 consists of a clamping ring 21 and a pull rod 22. The clamping ring 21 is nested in the No. 1 interval 12, and the clamping ring 21 contacts the portion of the telescopic rod 11 close to the No. 1 interval 12; a pull rod 22 is provided on one side of the clamping ring 21 close to the No. 1 ring 13, and the pull rod 22 passes through the No. 1 ring 13. The middle portion of the clamping ring 21 clamps the detonator.

[0036] During operation, in a blasting project, a detonator needs to be inserted into a blasthole. Before inserting the detonator into the blasthole, the detonator is first nested on the clamping ring 21, and the aperture of the middle part of the No. 1 ring 13 and the No. 2 ring 14 is equal to the diameter of the detonator, and the blasthole aperture is larger than the outer diameter of the No. 2 ring 14; the No. 2 ring 14 is inserted into the blasthole, and the detonator does not extend out of the No. 2 ring 14 at this time, so as to prevent the detonator from being damaged by collision during the forward movement of the extension mechanism 1. Then, the multi-stage telescopic rod 11 can be extended according to the depth of the blasthole, and the pull rod 22 of different lengths can be selected according to the depth of the blasthole. In the process of the telescopic rod 11 extending into the blasthole, this device can detect The depth of the blasthole is prevented from collapsing and being blocked; when the telescopic rod 11 is extended to the specified position, the telescopic rod 11 is stopped from being extended, and the No. 2 ring 14 is fixed to the entrance of the blasthole, and the pull rod 22 is adjusted to make the detonator extend out of the No. 2 ring 14 and contact the explosive; when it is found that the detonator is faulty, the pull rod 22 is pulled to make the clamping ring 21 slide on the inner wall of the telescopic rod 11, which facilitates the removal of the detonator. In this process, it is effectively avoided that the detonator touches the hole wall, causing the blasthole to collapse and affecting the secondary filling; and the collapse of the blasthole is avoided, thereby avoiding the soil blocking the explosive, and avoiding the soil blocking the detonator and the explosive when the detonator is installed next time, affecting the detonation of the explosive.

[0037] As a specific embodiment of the present invention, the pull rod 22 is threadedly connected to the No. 1 rod 23, and the No. 1 rod 23 is nested in the clamping ring 21. The other end of the No. 1 rod 23 is rotatably connected to the No. 3 rod 24, and the angle between the No. 1 rod 23 and the No. 3 rod 24 is an acute angle; the other end of the No. 3 rod 24 is rotatably connected to the No. 2 rod 25, and the No. 2 rod 25 is nested in the clamping ring 21. The No. 1 rod 23 and the No. 2 rod 25 are 90 degrees to each other, and a clamping block 26 is fixed to the end of the No. 2 rod 25 away from the inside of the clamping ring 21.

[0038] During operation, when a detonator failure is found and needs to be pulled out, if the hole is already filled with gun mud or the pulling resistance is large, the detonator is likely to fall off during the pulling process; therefore, when the pull rod 22 is pulled, this arrangement causes the No. 1 rod 23 to move toward the exit of the blast hole. Due to the connection between the No. 1 rod 23 and the No. 3 rod 24 and the limitation of the No. 2 rod 25 by the clamping ring 21, combined with the motion knowledge of the four-bar mechanism, the No. 2 rod 25 moves toward the middle part of the clamping ring 21, thereby pushing the clamping block 26 to extend toward the central part of the clamping ring 21, thereby clamping the detonator, making it difficult for the detonator to fall off during the pulling process; and when the pull rod 22 is pushed, the clamping block 26 will also retract, so it does not affect the initial installation of the detonator.

[0039] As a specific implementation of the present invention, a groove 261 is provided on a side of the clamping block 26 away from the clamping ring 21 .

[0040] During operation, a groove 261 is provided on the side of the clamping block 26 away from the clamping ring 21. This arrangement allows the clamping block 26 to extend out and contact the surface of the detonator. Due to the presence of the groove 261, the unevenness of the surface of the clamping block 26 is increased, thereby hindering the relative movement between the detonator and the clamping block 26. This further ensures that the detonator is not easy to fall off during the pulling process, thereby ensuring the normal operation of the device.

[0041] As a specific implementation of the present invention, a ball 211 is provided at the contact portion between the clamping ring 21 and the telescopic rod 11 .

[0042] During operation, a ball 211 is provided at the contact portion between the clamping ring 21 and the telescopic rod 11. When the clamping ring 21 moves relative to the telescopic rod 11, this arrangement allows sliding friction between the clamping ring 21 and the telescopic rod 11, making it easier for the clamping ring 21 to move relative to the telescopic rod 11, making it easier for the clamping ring 21 to be pulled out or pushed in; thereby making it more convenient to pull out and put in the detonator; and ensuring the normal function of the device.

[0043] As a specific implementation of the present invention, a plurality of arc-shaped hooks 111 are evenly arranged on the surface of the telescopic rod 11 away from the No. 1 section 12 , and the hooks 111 are bent toward the direction of the No. 1 ring 13 .

[0044] During operation, a plurality of arc-shaped hooks 111 are evenly arranged on the surface of the telescopic rod 11 away from the No. 1 interval 12, and the hooks 111 are bent toward the direction of the No. 1 ring 13. When the telescopic rod 11 enters the blast hole, there is little obstruction between the hooks 111 and the side wall of the blast hole, making it easy for the telescopic rod 11 to be placed in the blast hole. When the telescopic rod 11 wants to move outward, the hooks 111 will hook the side wall of the blast hole, making it difficult for the telescopic rod 11 to move out, thereby ensuring the stability of the telescopic rod 11 in the blast hole and making it difficult for the telescopic rod 11 to be pulled out.

[0045] As a specific implementation of the present invention, the hook 111 is rotatably connected to the telescopic rod 11 .

[0046] During operation, the hook 111 is rotatably connected to the telescopic rod 11. When the telescopic rod 11 enters the blasthole, the hook 111 rotates toward the blasthole exit, so that the obstruction of the blasthole to the hook 111 is minimized, and the telescopic rod 11 is further easily put into the blasthole; when the telescopic rod 11 wants to move outward, the hook 111 rotates away from the blasthole exit. This process causes the hook tip to scratch the side wall of the blasthole, further increasing the obstruction of the blasthole to the hook 111, and further making it difficult for the telescopic rod 11 to move out, further ensuring the stability of the telescopic rod 11 in the blasthole, and making it difficult for the telescopic rod 11 to be pulled out.

[0047] The specific workflow is as follows:

[0048] In the blasting project, it is necessary to insert the detonator into the blasthole. Before inserting the detonator into the blasthole, the detonator is first nested on the clamping ring 21, and the aperture of the middle part of the No. 1 ring 13 and the No. 2 ring 14 is equal to the diameter of the detonator, and the blasthole aperture is larger than the outer diameter of the No. 2 ring 14; the No. 2 ring 14 is inserted into the blasthole, and the detonator does not extend out of the No. 2 ring 14 at this time, so as to prevent the detonator from being damaged by collision during the forward movement of the extension mechanism 1. Subsequently, the multi-stage telescopic rod 11 can be extended according to the depth of the blasthole, and the pull rod 22 of different lengths can be selected according to the depth of the blasthole. In the process of the telescopic rod 11 extending into the blasthole, this device can detect the depth of the blasthole to prevent the blasthole from collapsing and being blocked; when the telescopic rod 11 is extended to the specified position, the telescopic rod 11 is stopped from being extended, and the No. 2 ring 14 is fixed to the entrance of the blasthole, and the pull rod 22 is adjusted to make the detonator extend out of the No. 2 ring 14 and contact the explosive; when the detonator is found to be faulty , pull the pull rod 22 to make the clamping ring 21 slide on the inner wall of the telescopic rod 11, which is convenient for taking out the detonator. In this process, it is effectively avoided that the detonator touches the hole wall, causing the blast hole to collapse and affecting the secondary filling; and the blast hole collapse is avoided, thereby avoiding the soil blocking the explosive, and avoiding the soil blocking the detonator and the explosive when the detonator is loaded next time, affecting the detonation of the explosive; in addition, the surface of the telescopic rod 11 away from the No. 1 interval 12 is evenly provided with a plurality of arc-shaped hooks 111, and the hooks 111 are bent in the direction of the No. 1 ring 13. When the telescopic rod 11 enters the blast hole, the obstruction between the hooks 111 and the side wall of the blast hole is small, and the telescopic rod 11 is easy to be put into the blast hole. When the telescopic rod 11 wants to move outward, the hooks 111 will hook the side wall of the blast hole, making it difficult for the telescopic rod 11 to move out, ensuring the stability of the telescopic rod 11 in the blast hole, and making it difficult for the telescopic rod 11 to be pulled out.
