[0001] The utility model relates to the technical field of blasting tubes used in mine development, in particular to a blasting tube used in mine development. Background Art
[0002] In mining, blasting tubes are one of the key tools for implementing blasting operations. They are mainly used to control and detonate explosives to achieve the crushing of rocks or mineral layers. The blasting tubes used in mining usually include electric detonators, non-electric detonators, detonating cords and the recently developed carbon dioxide blasting tubes. The explosive blasting is powerful and has a strong effect. It is a typical open flame blasting and has high requirements for the use conditions, use environment, daily management, etc. Therefore, most people use carbon dioxide blasting technology to mine.
[0003] When using blasting tubes in current mines, workers often find that the carbon dioxide blasting tubes used in current mines are usually connected to a detonating wire. When placing the blasting tube, the worker usually holds one end of the detonating wire and then places the blasting tube in the blast hole and lets it slide down. Due to the large mass of the blasting tube, a large impact force is generated during the sliding process, and the detonating wire is easy to fall off from the worker's hand, resulting in the scrapping of the blasting tube. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a blasting tube for mine development.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a blasting tube for mining, comprising a blasting tube body, two air leakage holes are provided on the blasting tube body, a limiting structure is provided on the blasting tube body, the limiting structure is mainly composed of a limiting block, a rotating shaft is rotatably connected to the limiting block, a connecting line is fixedly connected to the rotating shaft, the connecting line is fixedly connected to the blasting tube body, a rectangular plate is fixedly connected to the limiting block, a pin is slidably inserted on the rectangular plate, a circular hole is provided on the rotating shaft, and the pin is adapted to the size of the circular hole.
[0006] The effect achieved by the above components is: the connecting wire is wound around the rotating shaft, and the sliding pin is stuck into the round hole to limit the rotating shaft to prevent it from rotating. The staff places the limit block at the blasthole, puts the blasting tube body into the blasthole, slides the pin out of the round hole, and the rotating shaft rotates under the action of the gravity of the blasting tube body. When the blasting tube body reaches the specified position, the connecting wire is just unwound, and there is no need for the staff to manually pull it, thereby avoiding the current carbon dioxide blasting tube used in mining, which is usually connected to a detonating wire. When placing the blasting tube, the staff usually holds one end of the detonating wire, and then places the blasting tube in the blasthole and lets it slide down. Due to the large mass of the blasting tube, a large impact force will be generated during the sliding process, and the detonating wire is easy to fall off from the staff's hands, resulting in the scrapping of the blasting tube.
[0007] Preferably, a rectangular block is fixedly connected to the limit block, a round rod is slidably inserted into the rectangular block, a clamping block is fixedly connected to one end of the round rod, and a clamping slot is provided on the latch.
[0008] The effect achieved by the above components is: the sliding round rod allows the card block to be stuck in the card slot, which can limit the pin and prevent the pin from slipping out of the round hole during movement.
[0009] Preferably, a second spring is sleeved on the round rod, one end of the second spring is fixedly connected to the round rod, and the other end of the second spring is fixedly connected to the rectangular block.
[0010] The effect achieved by the above components is that when the card block is inserted into the card slot, the second spring is in a stretched state, so the rebound force of the second spring acts on the round rod, making the limit more stable.
[0011] Preferably, a first spring is sleeved on the latch, one end of the first spring is fixedly connected to the latch, and the other end of the first spring is fixedly connected to the rectangular plate.
[0012] The effect achieved by the above components is that when the pin is stuck in the round hole, the first spring is in a contracted state. Therefore, when the block is released from limiting the pin, the pin slides to the right under the action of the rebound force of the first spring, making the unwinding operation more convenient.
[0013] Preferably, a first motor is fixedly connected to the limiting block, and an output shaft of the first motor is fixedly connected to the rotating shaft.
[0014] The effect achieved by the above components is: after the blasting is completed, the first motor is started, and the output shaft of the first motor drives the rotating shaft to rotate, and the connecting wire can be reeled in, which facilitates the recycling of the blasting tube body.
[0015] Preferably, a fixing structure is provided on the limit block, and the fixing structure is mainly composed of two threaded rods. The two threaded rods are both threadedly inserted into the limit block, and a spiral block is fixedly connected to the threaded rods.
[0016] The effect achieved by the above components is that the two threaded rods are rotated to insert the spiral block into the ground, which can make the position of the limit block more stable.
[0017] Preferably, a rotating shaft is rotatably connected to the limit block, and pulleys are fixedly connected to the rotating shaft and the two threaded rods, and a transmission belt is commonly provided on the three pulleys.
[0018] The effect achieved by the above components is: rotating the shaft can drive a pulley to rotate. Under the action of the transmission belt, the three pulleys rotate synchronously, causing the two threaded rods to rotate synchronously, and then driving the two spiral blocks to be inserted into the ground synchronously, making the operation more convenient.
[0019] Preferably, a second motor is fixedly connected to the limiting block, and an output shaft of the second motor is fixedly connected to the rotating shaft.
[0020] The effect achieved by the above components is: when the second motor is started, the output shaft of the second motor drives the rotating shaft to rotate, making the operation of fixing the limit block more labor-saving.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting a limiting structure, the connecting wire is wound around the rotating shaft, and the sliding pin is stuck in the round hole, which can limit the rotating shaft to prevent it from rotating. The staff places the limiting block at the blast hole, puts the blasting tube body into the blast hole, slides the pin out of the round hole, and the rotating shaft rotates under the action of the gravity of the blasting tube body. When the blasting tube body reaches the specified position, the connecting wire is just unwound, and there is no need for the staff to manually pull it. The sliding round rod makes the block stuck in the slot, which can limit the pin to prevent the pin from slipping out of the round hole during movement. When the block is stuck in the slot, the second spring is in a stretched state, so the rebound elastic force of the second spring acts on the round rod, making the limit more stable. When the latch is stuck in the round hole, the first spring is in a contracted state. Therefore, when the limit of the latch on the block is released, the latch slides to the right under the action of the rebound force of the first spring, making the unwinding operation more convenient. After the blasting is completed, the first motor is started, and the output shaft of the first motor drives the rotating shaft to rotate, so that the connecting wire can be reeled up, which is convenient for recycling the blasting tube body, thereby avoiding the current carbon dioxide blasting tube used in mines. Usually, a detonating wire is connected to the blasting tube. When placing the blasting tube, the worker usually holds one end of the detonating wire and then places the blasting tube in the blasthole to let it slide down. Due to the large mass of the blasting tube, a large impact force will be generated during the sliding process, and the detonating wire is easy to fall off from the worker's hand, resulting in the scrapping of the blasting tube.

[0028] Reference Figure 2 and Figure 4, a limiting structure 3 is provided on the blasting tube body 1, and the limiting structure 3 is mainly composed of a limiting block 31, a rotating shaft 32 is rotatably connected to the limiting block 31, a connecting line 33 is fixedly connected to the rotating shaft 32, and the connecting line 33 is fixedly connected to the blasting tube body 1, a rectangular plate 34 is fixedly connected to the limiting block 31, a latch 35 is slidably inserted on the rectangular plate 34, a circular hole 36 is opened on the rotating shaft 32, the latch 35 is adapted to the size of the circular hole 36, the connecting line 33 is wound around the rotating shaft 32, and the sliding latch 35 is stuck into the circular hole 36, which can limit the rotating shaft 32 to prevent it from rotating. The staff places the limiting block 31 at the blasthole, puts the blasting tube body 1 into the blasthole, and The latch 35 slides out of the circular hole 36, and the rotating shaft 32 rotates under the action of gravity of the blasting tube body 1. The blasting tube body 1 reaches the specified position, and the connecting line 33 is just unwound, and there is no need for the staff to manually pull it, thereby avoiding the current carbon dioxide blasting tube used in mining usually connected to a detonating line. When placing the blasting tube, it is usually held by the staff at one end of the detonating line, and then placed in the blasting tube in the blasthole, and let it slide down. Due to the large mass of the blasting tube, a large impact force will be generated during the sliding process, and the detonating line is easy to fall off from the staff's hands, resulting in the scrapping of the blasting tube. A rectangular block 39 is fixedly connected to the limit block 31, and a sliding plug is provided on the rectangular block 39 When the locking block 312 is inserted into the slot 38, the second spring 311 is in a stretched state, so that the rebound force of the second spring 311 acts on the round rod 310, making the limit more stable. One end of a spring 37 is fixedly connected to the latch 35, and the other end of the first spring 37 is fixedly connected to the rectangular plate 34. When the latch 35 is stuck in the circular hole 36, the first spring 37 is in a contracted state. Therefore, when the block 312 is released to limit the latch 35, the latch 35 slides to the right under the action of the rebound force of the first spring 37, making the unwinding operation more convenient. A first motor 313 is fixedly connected to the limit block 31, and the output shaft of the first motor 313 is fixedly connected to the rotating shaft 32. After the blasting is completed, the first motor 313 is started, and the output shaft of the first motor 313 drives the rotating shaft 32 to rotate, so that the connecting line 33 can be reeled up, which is convenient for recycling the blasting tube body 1.
[0029] Reference Figure 3The limit block 31 is provided with a fixing structure 4, which is mainly composed of two threaded rods 41. The two threaded rods 41 are threadedly inserted into the limit block 31, and the threaded rods 41 are fixedly connected to a spiral block 42.

The limit block 31 is rotatably connected to a rotating shaft 43, and the rotating shaft 43 and the two threaded rods 41 are fixedly connected to pulleys 44. The three pulleys 44 are jointly provided with a transmission belt 45. Rotating the rotating shaft 43 can drive one pulley 44 to rotate. Under the action of the transmission belt 45, the three pulleys 44 rotate synchronously, so that the two threaded rods 41 rotate synchronously, and then drive the two spiral blocks 42 to be inserted into the ground synchronously, making the operation more convenient. The limit block 31 is fixedly connected to a second motor 46, and the output shaft of the second motor 46 is fixedly connected to the rotating shaft 43. When the second motor 46 is started, the output shaft of the second motor 46 drives the rotating shaft 43 to rotate, making the operation of fixing the limit block 31 more labor-saving.

The rotating shaft 32 rotates under the action of gravity of the blasting tube body 1. When the blasting tube body 1 reaches the specified position, the connecting wire 33 is just unwound, and there is no need for the staff to manually pull it, thereby avoiding the current use of carbon dioxide blasting in mines. The tube is usually connected to a detonating wire. When placing the blasting tube, a worker usually holds one end of the detonating wire in his hand, and then places the blasting tube in the blasthole and lets it slide down. Due to the large mass of the blasting tube, a large impact force is generated during the sliding process, and the detonating wire is easy to fall off from the worker's hand, resulting in the scrapping of the blasting tube. The sliding round rod 310 allows the block 312 to be stuck in the slot 38, which can limit the pin 35 to prevent the pin 35 from sliding out of the round hole 36 during the movement. When the block 312 is stuck in the slot 38, the first The second spring 311 is in a stretched state, so the rebound force of the second spring 311 acts on the round rod 310, making the limit more stable. When the latch 35 is stuck in the round hole 36, the first spring 37 is in a contracted state. Therefore, when the block 312 is released to limit the latch 35, the latch 35 slides to the right under the action of the rebound force of the first spring 37, making the unwinding operation more convenient. After the blasting is completed, the first motor 313 is started, and the output shaft of the first motor 313 drives the rotating shaft 32 to rotate, so that the connecting line 33 can be reeled in, which is convenient The blasting tube body 1 is recycled, and the two threaded rods 41 are rotated to insert the spiral block 42 into the ground, which can make the position of the limit block 31 more stable. The rotating shaft 43 can drive a pulley 44 to rotate. Under the action of the transmission belt 45, the three pulleys 44 rotate synchronously, so that the two threaded rods 41 rotate synchronously, and then drive the two spiral blocks 42 to be inserted into the ground synchronously, making the operation more convenient. The second motor 46 is started, and the output shaft of the second motor 46 drives the rotating shaft 43 to rotate, making the operation of fixing the limit block 31 more labor-saving.
