Description

Technical Field

[0001] This utility model relates to the technical field of explosive loading rods for blasting, and in particular to an explosive loading rod for blasting. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and killing effects produced by the explosion of explosives in air, water, soil, rock, or objects to achieve a desired purpose. It is mainly used in earthwork engineering and the demolition of metal buildings and structures. A blasting explosive loading rod is a tool used in blasting operations to load explosives into blast holes.

[0003] During the use of current explosive loading rods, staff often find that most of them are made of wood, plastic or metal of different lengths. Because some blasting holes are deep, the required loading rods are also long, making them inconvenient to carry. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blasting explosive loading rod.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a loading rod for explosives, comprising a loading rod body, wherein a connecting structure is provided on the loading rod body, the connecting structure mainly consisting of connecting blocks, the connecting blocks being fixedly connected to one end of the loading rod body, and a connecting groove being provided at the other end of the loading rod body, the connecting blocks being adapted to the size of the connecting groove, the loading rod body at the head having only a connecting groove, and the loading rod body at the tail having only a connecting block being fixedly connected, a scale being provided on the loading rod body, and marker blocks being fixedly connected to both the loading rod body at the head and tail.

[0006] The effect achieved by the above components is as follows: the staff can easily identify the head rod and the tail rod by using two marker blocks to prevent installation errors. Then, according to the depth of the blast hole, the head rod, an appropriate number of intermediate rods and the tail rod are installed in sequence, that is, the connecting block is snapped into the corresponding connecting groove. The specific position of insertion can be determined by using a ruler, thereby avoiding the situation where some blast holes are deeper and therefore require longer loading rods, which would make them inconvenient to carry.

[0007] Preferably, sliding grooves are respectively provided on the inner walls of both sides of the connecting groove, and a locking block is slidably connected in the sliding groove, and a locking groove is respectively provided on both sides of the connecting block.

[0008] The effect achieved by the above components is that by sliding the two blocks into their corresponding slots, the connecting blocks can be limited, making the connection more stable.

[0009] Preferably, a round rod is slidably inserted into the groove, one end of the round rod is fixedly connected to a round block, and the other end of the round rod is fixedly connected to a locking block.

[0010] The above-mentioned components achieve the following effect: the operator can move the locking block by sliding the round rod, making the operation more convenient. The round block is made of rubber.

[0011] Preferably, a spring is fitted onto the round rod, one end of the spring is fixedly connected to the locking block, and the other end of the spring is fixedly connected to the inner wall of the slide groove.

[0012] The effect achieved by the above components is as follows: when the connecting block is inserted into the connecting groove, the connecting block will push the inclined surfaces of the two locking blocks, causing the two locking blocks to slide into the sliding groove. At this time, the spring will be compressed and contracted. Therefore, when the locking block contacts the groove, the locking block will be inserted into the corresponding groove under the action of the spring's rebound force, further improving the convenience of the connection operation.

[0013] Preferably, the loading rod body is provided with an anti-static structure, which is mainly composed of wires. The wires are fixedly inserted inside the loading rod body, and metal plates are fixedly connected to both ends of the wires. One metal plate is fixedly connected to the connecting block, and the other metal plate is fixedly connected to the connecting groove. A metal block is fixedly connected to the loading rod body at the head, and a grounding clamp is fixedly connected to the wires on the loading rod body at the tail.

[0014] The effect achieved by the above components is as follows: During blasting operations, static electricity is easily generated by the friction between the loading rod body located at the head and the explosive, the borehole wall or other objects. This static electricity is conducted to the wire through the metal block. Since the wires on the two loading rod bodies are electrically connected by the metal plate, the static charge can be conducted along the wire and then to the grounding clamp, preventing the static electricity from accumulating at the loading end. The workers clamp the grounding clamp to the grounding stake or the grounding end of large metal equipment so that the static electricity can be discharged in time.

[0015] Preferably, a metal rod is fixedly connected to the wire, and both the inner and outer walls of the metal rod are coated with an antistatic layer.

[0016] The effects achieved by the above components are as follows: the metal rod can improve the strength of the entire loading rod body, and the antistatic layer contains conductive particles. These particles are interconnected to form a conductive network. Once static electricity is generated, it can be quickly conducted through this conductive network to prevent static electricity from accumulating on the surface of the metal rod.

[0017] Preferably, the metal rod is externally fitted with an insulating layer, which is made of rubber.

[0018] The effect achieved by the above components is that in blasting operations, there may be dampness or static electricity on the operator's body. The insulation layer can prevent the operator from being shocked by contact with the metal parts, thus ensuring the operator's personal safety.

[0019] Preferably, the insulating layer has several protrusions fixedly connected to it.

[0020] The above components achieve the following effect: the metal rod, antistatic layer, insulating layer and protrusions together constitute the filling rod body. The protrusions can increase the friction between the filling rod body and the user, making it convenient for staff to use.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a connecting structure, the staff can easily identify the head rod and the tail rod by using two marker blocks to prevent installation errors. Then, according to the depth of the blast hole, the head rod, an appropriate number of intermediate rods and the tail rod are installed in sequence, that is, the connecting block is snapped into the corresponding connecting groove. The specific position of insertion can be determined by using a ruler, thereby avoiding the situation where some blast holes are deep and therefore require a long loading rod, which would be inconvenient to carry.

[0028] Reference Figure 2 and Figure 3 The loading rod body 1 is provided with a connecting structure 2, which mainly consists of a connecting block 21. The connecting block 21 is fixedly connected to one end of the loading rod body 1, and a connecting groove 22 is opened at the other end of the loading rod body 1. The connecting block 21 and the connecting groove 22 are adapted to each other. Only the connecting groove 22 is opened on the loading rod body 1 at the head, and only the connecting block 21 is fixedly connected on the loading rod body 1 at the tail. A scale 29 is provided on the loading rod body 1, and both the head and tail of the loading rod body 1 are fixedly connected to... With marker blocks 210, workers can easily identify the head rod and tail rod using two marker blocks 210 to prevent installation errors. Then, according to the depth of the blast hole, the head rod, an appropriate number of intermediate rods, and the tail rod are installed in sequence, that is, the connecting block 21 is inserted into the corresponding connecting groove 22. The specific insertion position can be determined by the scale 29, thus avoiding the situation where some blast holes are deeper and therefore require longer loading rods, which would be inconvenient to carry. Sliding grooves are respectively opened on the inner walls of both sides of the connecting groove 22. 23. A locking block 24 is slidably connected in the slide groove 23. Slots 25 are respectively opened on both sides of the connecting block 21. Sliding the two locking blocks 24 into their corresponding slots 25 limits the connection of the connecting block 21, making the connection more stable. A round rod 26 is slidably inserted in the slide groove 23. One end of the round rod 26 is fixedly connected to a round block 27, and the other end of the round rod 26 is fixedly connected to the locking block 24. The operator can move the locking block 24 by sliding the round rod 26, making operation more convenient. The round block 27 is made of rubber. A spring 28 is provided on the upper sleeve. One end of the spring 28 is fixedly connected to the locking block 24, and the other end of the spring 28 is fixedly connected to the inner wall of the slide groove 23. When the connecting block 21 is inserted into the connecting groove 22, the connecting block 21 will push the inclined surfaces of the two locking blocks 24, causing the two locking blocks 24 to slide into the slide groove 23. At this time, the spring 28 will be compressed and contracted. Therefore, when the locking block 24 contacts the locking groove 25, the locking block 24 will be inserted into the corresponding locking groove 25 under the action of the spring 28's rebound force, further improving the convenience of the connection operation.

[0029] Reference Figure 1 and Figure 4The loading rod body 1 is equipped with an anti-static structure 3, which mainly consists of wires 31. The wires 31 are fixedly inserted inside the loading rod body 1, and metal plates 37 are fixedly connected to both ends of the wires 31. One metal plate 37 is fixedly connected to the connecting block 21, and the other is fixedly connected to the connecting groove 22. A metal block 38 is fixedly connected to the loading rod body 1 at the head, and a grounding clamp 32 is fixedly connected to the wires 31 at the tail. During blasting operations, static electricity is easily generated by friction between the loading rod body 1 at the head and explosives, borehole walls, or other objects. This static electricity is conducted to the wires 31 through the metal block 38. Because the wires 31 on the two loading rod bodies 1 are electrically connected through the metal plates 37, the static charge can be conducted along the wires 31, and then to the grounding clamp 32, preventing static electricity accumulation at the loading end. Workers then clamp the grounding clamp 32 to the grounding stake or the grounding end of large metal equipment. Static electricity can be promptly discharged. A metal rod 33 is fixedly connected to the wire 31. Both the inner and outer walls of the metal rod 33 are coated with an antistatic layer 34. The metal rod 33 can improve the strength of the entire loading rod body 1. The antistatic layer 34 contains conductive particles, which are interconnected to form a conductive network. Once static electricity is generated, it can be quickly conducted through this conductive network, preventing static electricity from accumulating on the surface of the metal rod 33. An insulating layer 35 is fixedly sleeved on the outside of the metal rod 33. The insulating layer 35 is made of rubber. In the blasting operation environment, there may be moisture or static electricity on the operator's body. The insulating layer 35 can prevent the operator from being shocked by contact with the metal part, ensuring the operator's personal safety. Several protrusions 36 are fixedly connected to the insulating layer 35. The metal rod 33, the antistatic layer 34, the insulating layer 35, and the protrusions 36 together constitute the loading rod body 1. The protrusions 36 can increase the friction between the loading rod body 1 and the user, making it convenient for the staff to use.

[0030] Working principle: Workers can easily identify the head rod and tail rod using two marker blocks 210 to prevent installation errors. Then, based on the depth of the blast hole, the head rod, an appropriate number of intermediate rods, and the tail rod are installed sequentially. This involves inserting the connecting block 21 into the corresponding connecting groove 22. The exact insertion position can be determined using a scale 29, thus avoiding the situation where some blast holes are deep and require longer loading rods, making them inconvenient to carry. Sliding the two locking blocks 24 into the corresponding locking grooves 25 limits the connection block 21, ensuring the connection... For a more stable connection, workers can move the locking block 24 by sliding the round rod 26, making the operation more convenient. The round block 27 is made of rubber. When the connecting block 21 is inserted into the connecting groove 22, the connecting block 21 will push the inclined surfaces of the two locking blocks 24, causing the two locking blocks 24 to slide into the sliding groove 23. At this time, the spring 28 will be compressed and contracted. Therefore, when the locking block 24 contacts the groove 25, the locking block 24 will be inserted into the corresponding groove 25 under the action of the spring 28's rebound force, further improving the convenience of the connection operation. In blasting operations, the loading rod body 1 located at the head and Friction from explosives, borehole walls, or other objects easily generates static electricity, which is conducted through the metal block 38 to the wire 31. Since the wires 31 on the two loading rod bodies 1 are electrically connected by the metal plate 37, the static charge can be conducted along the wires 31, and then to the grounding clamp 32, preventing static electricity from accumulating at the loading end. Workers clamp the grounding clamp 32 to a grounding stake or the grounding end of large metal equipment, allowing the static electricity to be discharged promptly. The metal rod 33 increases the overall strength of the loading rod body 1. The antistatic layer 34 contains conductive particles. The particles are interconnected to form a conductive network. Once static electricity is generated, it can be quickly conducted through this conductive network, preventing the accumulation of static electricity on the surface of the metal rod 33. In the blasting operation environment, there may be dampness or static electricity on the operator's body. The insulating layer 35 can prevent the operator from being shocked by contact with the metal part, ensuring the operator's personal safety. The metal rod 33, the antistatic layer 34, the insulating layer 35 and the protrusion 36 together constitute the loading rod body 1. The protrusion 36 can increase the friction between the loading rod body 1 and the user, making it convenient for the staff to use.
