Description

Technical Field

[0001] This utility model relates to the technical field of tunnel engineering equipment, and in particular to a blasting trigger control device. Background Technology

[0002] In the process of tunnel construction, advance prediction technology is an indispensable means to detect unfavorable geological bodies within a certain range in front of the tunnel excavation face in advance and effectively avoid geological risks. Among them, the blast source seismic wave method advance prediction is to generate seismic waves by blasting explosives and determine the location of unfavorable geological bodies by analyzing the information of the reflected echoes. The TGP method and TSP method are the most common.

[0003] When conducting advance prediction using the blast-source seismic wave method, complex preparatory work is generally required. This method necessitates installing detonators and severing trigger wires in multiple pre-drilled holes in the tunnel sidewall. During data acquisition, data acquisition personnel and blasting personnel must connect detonators and sever trigger wires in each hole before each blast, and then retreat to a safe blasting distance before carrying out the blast and receiving data. Each round trip to each hole takes at least five minutes, resulting in extremely low overall work efficiency and impacting the tunnel construction schedule. Furthermore, during the personnel's round trip, due to the instability of the tunnel walls, there is a possibility of falling debris, posing a safety hazard of personnel being injured by falling debris.

[0030] The following is combined with Figures 1-2This invention describes a blasting trigger control device, comprising an industrial computer 1, a trigger cable, and a trigger component 3. The industrial computer 1 is provided with a trigger socket 14, and one end of the trigger cable is provided with a plug 21, which is plugged into the trigger socket 14. The trigger cable is provided with multiple interfaces 22 at intervals. One end of the trigger component 3 is located in the interface 22, and the other end of the trigger component 3 is located in the blasting hole 4. The industrial computer 1 is provided with a control motherboard 15, and the trigger socket 14 is provided with multiple sockets 141. Each socket 141 is electrically connected to the control motherboard 15, and the multiple interfaces 22 are electrically connected to the multiple sockets 141 in a one-to-one correspondence to form multiple triggering circuits, and each triggering component 3 can be controlled through each triggering circuit. In tunnel blasting projects, it is often necessary to blast multiple blasting holes 4. Connecting multiple blasting holes 4 one by one results in low efficiency and increases the safety risks for workers. In this embodiment, by setting multiple interfaces 22 on the trigger cable and connecting the triggering component 3 to the interfaces 22, it is possible to achieve independent control of each triggering component 3. This allows for sequential control of each triggering component 3 after a single connection, improving work efficiency and safety.

[0031] Specifically, the industrial computer 1 includes a housing and a control motherboard 15 and other necessary electronic components inside the housing, such as power supply and connection lines. A trigger port 14 is located on the industrial computer 1 and is plugged in via a connector 21, thereby energizing the trigger cable. The trigger cable body has multiple interfaces 22 spaced apart, each interface 22 corresponding to a single socket 141. This ensures that each interface 22 and each socket 141 form an independent electrical circuit after electrical connection, allowing independent control after connecting the trigger component 3 to each interface 22.

[0032] In the specific setup, multiple blasting holes (i.e., blasting holes 4) are pre-reserved in the tunnel sidewall, numbered sequentially from the tunnel face to the tunnel entrance. Explosive detonators 5 are then installed in the blasting holes 4, and one end of the triggering component 3 is placed inside the blasting hole 4. When blasting is required, energizing the triggering component 3 activates the explosive detonator 5, causing the explosion. The entire triggering process can be remotely controlled, and after each operation, the remaining triggering components 3 can be controlled sequentially, thus achieving safe control and improving work efficiency and safety.

[0033] Understandably, 24 blasting holes 4 are typically required during blasting operations, with a total length of approximately 70m. Conventional methods require sequential blasting, which is inefficient and increases safety risks due to repeated connections. This embodiment improves efficiency and safety by using multiple interfaces 22 on the trigger cable, allowing for simultaneous connection and independent control of the triggering component 3 within each interface 22.

[0034] Specifically, the trigger cable includes multiple copper core wires with progressively increasing lengths, so that each copper core wire can be connected to each interface 22 in a one-to-one correspondence and form an independent trigger circuit.

[0035] In some embodiments, the triggering component 3 includes a triggering conductor rod 31. One end of the triggering conductor rod 31 is provided with an insulating protective sleeve 33, and a contact copper piece 34 is provided inside the protective sleeve. The contact copper piece 34 is electrically connected to the triggering cable. The other end of the triggering conductor rod 31 extends into the blast hole 4 to trigger the explosive after energization. During blasting operations, a power supply is required to trigger the explosive and cause it to detonate. In this embodiment, the triggering conductor rod is energized, thereby triggering the detonating device and causing the explosive to detonate.

[0036] Specifically, such as Figure 6 As shown, a detonator is installed inside the blast hole 4. The detonator is used to detonate the explosive. It is an electric detonator, which detonates by inputting current. Specifically, one end of the contact copper plate 34 is connected to the trigger conductive rod, and the other end of the contact copper plate 34 is in contact with a copper core wire in the trigger cable, thereby achieving electrical connection.

[0037] In conjunction with the above embodiments, a wiring clamp 32 is provided on the body of the trigger conductor rod 31. During installation, it is necessary to ensure the stability of the trigger conductor rod connection. In this embodiment, the connection stability is improved through the wiring clamp 32, ensuring that one end of the trigger conductor rod 31 can be stably positioned within the blast hole 4.

[0038] Specifically, the blast hole 4 is located on the wall of the tunnel. The trigger conductor rod 31 can be stably installed on the wall by the wiring clamp 32, thereby improving its stability.

[0039] In some embodiments, the industrial computer 1 is also equipped with an indicator light 13, which is electrically connected to the control motherboard 15. After each trigger component 3 is connected to each interface 22, it is necessary to detect whether the connection is in place. This is done by providing feedback through the indicator light 13 to ensure effective feedback and thus ensure that each trigger component 3 is connected in place.

[0040] In a specific configuration, the plug portion 21 is provided with multiple positive pins 211 and one negative pin 212 for connecting to the trigger socket 14. The negative pin 212 is electrically connected to each positive pin 211 to form multiple trigger circuits.

[0041] Specifically, the negative terminal of each circuit is connected in parallel with the negative terminal pin 212 to form multiple trigger circuits, thereby realizing independent power supply control for each trigger component 3.

[0042] The indicator light 13 is located in the negative circuit and is equipped with a control circuit. It displays a red light when any circuit is open and a green light when all trigger circuits are connected. Of course, the color change of indicator light 13 can also be controlled by a program.

[0043] In conjunction with the above embodiments, the negative pin 212 is located at the center of the plug portion 21, and multiple positive pins 211 are arranged in a circular array around the negative pin 212. This circular array arrangement enables effective insertion of each pin and makes the overall arrangement more compact.

[0044] Specifically, multiple positive electrode pins 211 are arranged to form an inner ring structure and an outer ring structure. This arrangement enables the independence of each pin and achieves a compact overall structure.

[0045] In some embodiments, the industrial control computer 1 is equipped with a display 11, which is electrically connected to the control motherboard 15. The display 11 is used to display circuit information. The on / off information of each trigger circuit is displayed on the display 11 to make it more intuitive and facilitate the troubleshooting of on / off states.

[0046] Specifically, the display 11 can reflect the on / off information of each trigger circuit, and can promptly and effectively troubleshoot when an open circuit occurs.

[0047] In a specific embodiment, the industrial computer 1 is equipped with a power switch 12, and the power switch 12, indicator light 13, and trigger socket 14 are located on the same side. This design makes the overall structure more compact and easier to operate.

[0048] Specifically, the industrial computer 1 has a display 11 on one side, and the power switch 12, indicator light 13 and trigger socket 14 are all located on one side of the display 11, which facilitates the overall operation.

[0049] In some embodiments, such as Figure 3 , Figure 4 As shown, a limiting groove 213 is provided in the plug portion 21, and a corresponding mating portion 142 is provided in the trigger socket 14. The limiting groove 213 and the mating portion 142 cooperate to limit the connection. During insertion, in order to ensure that each socket 141 corresponds to the pin on each plug portion 21, the limiting groove 213 and the mating portion 142 are used to limit the connection, so that they correspond one by one after insertion, ensuring correct connection.

[0050] In a specific implementation, the spacing between adjacent interfaces 22 is 1.5m-2m. This spacing ensures a one-to-one correspondence between the interfaces 22 and each blast hole 4.

[0051] The following specific examples will illustrate this.

[0052] like Figure 1 , Figure 5 As shown, the control motherboard 15 inside the industrial computer 1 is equipped with a continuity detection circuit and a trigger control circuit. The continuity detection circuit is electrically connected to the indicator light 13, which detects continuity. The plug 21 at one end of the trigger cable has twenty-four positive pins 211 and a single negative pin 212. Each positive pin 211 can be plugged into a corresponding socket 141 to form twenty-four trigger circuits. The control motherboard 15 can control the energization of each trigger circuit. An interface 22 is provided every two meters on the trigger cable, and a trigger component 3 is installed in each interface 22. The trigger component 3 triggers the explosive in each blast hole 4. When the indicator light 13 performs feedback detection through the continuity detection circuit, a red light is displayed when any trigger circuit is open, and the number of open circuits is displayed on the display 11 of the industrial computer 1. A green light is displayed when all trigger circuits are connected.

[0053] During the actual operation, at work site 1 to 24, the drilling spacing is 1.5m to 2m. Prepare 24 strips of 100g to 150g emulsion explosives and detonators. After binding the triggering conductive rod to the explosives and detonators, install it in sequence at the bottom of the blasting hole 4. One end of the triggering conductive rod extends out of the hole and is electrically connected to the triggering cable. Plug the plug 21 into the triggering socket 14. The instrument and equipment installation is complete.

[0054] like Figure 1 As shown, turn on the power switch 12 of the industrial control computer 1. Through its internal program and trigger circuit, it sequentially supplies power to test the circuits connected in boreholes 1 through 24. Observe that indicator light 13 shows a green light, indicating that all closed circuits are normal. If indicator light 13 shows a red light, it indicates that a circuit is abnormal. The instrument host will display the abnormal circuit number. The abnormal circuit should be checked and the fault eliminated until indicator light 13 shows a green light, indicating that the trigger circuit is intact and the next step of data acquisition can proceed. During data acquisition, personnel and equipment should be kept away from the blast holes where explosives are installed. The industrial control computer 1 controls the sequential power supply to circuits 1 through 24, while professional blasting personnel blast sequentially according to the numbers 1 through 24, collecting vibration data in sequence. This avoids personnel repeatedly installing trigger circuits, testing pathways, and collecting blasting data, improving safety and work efficiency.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
