Description

Technical Field

[0001] The utility model relates to the technical field of blasting detection, in particular to a safe hole-by-hole detonation device for rocks. Background Art

[0002] Hole-by-hole detonation is a technical method used in blasting operations. It is usually used in rock blasting, mine blasting and civil engineering. Simply put, hole-by-hole detonation refers to detonating blasting holes in a certain order to achieve a more effective blasting effect. In hole-by-hole detonation, holes are usually pre-drilled in the rock or soil to be blasted, and then explosives or blasting devices are placed in these holes. Depending on the blasting design and blasting requirements, the position, depth and spacing of these holes may vary. Then, by detonating these holes one by one, the explosion wave propagates underground, thereby achieving destruction or movement of the rock or soil.

[0003] When the existing device detonates the blast network to detonate hole by hole, the explosion generates a stress wave to blast the ore around the hole. However, in order to ensure the explosion effect in the hole and avoid damage to the surrounding rock and filling body by the second explosion, the staff usually loads an excessive amount of explosives within the specified range in the hole. It is impossible to further adjust the subsequent blast network by detecting the stress wave of the explosion in advance, which results in the surrounding rock and filling body still being greatly damaged. The practicality needs to be improved. Utility Model Content

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a safe rock hole-by-hole detonating device, comprising a detonating device body 11 and an L-shaped plate 12, wherein the two L-shaped plates 12 are provided with positioning pins 13, the two L-shaped plates 12 are provided with square grooves 14, a baffle 15 is slidably installed between the two square grooves 14, and the opposite ends of the two L-shaped plates 12 are provided with a first slide groove 16 and a second slide groove 17 respectively;

[0026] A detection device is fixedly installed between the two L-shaped plates 12;

[0027] The detection device includes a connecting plate 18, a screw rod 19 is rotatably installed inside the connecting plate 18, and a part of the screw rod 19 is exposed above the connecting plate 18. A transmission block 21 is slidably installed between the two second slide grooves 17, and the transmission block 21 is threadedly installed with the screw rod 19. The detection device also includes a card slot 22, a slider 23, a shell 24, a stress wave sensor 25, and a card block 28. The card slot 22 is opened inside the transmission block 21, and the two sliders 23 are both located inside the first slide groove 16. The two sliders 23 are slidably installed with the first slide groove 16. The shell 24 is located between the sliders 23, and the shell 24 and the slider 23 are fixedly installed. By pre-testing the Two circular grooves engaged with the positioning pins 13 are opened in the rock near the test blasting network, so that the device can first install the L-shaped plate 12 as a whole on the rock, and then rotate the screw 19 to make the screw 19 and the transmission block 21 threadedly transmitted, and generate a radial force, thereby driving the block 28, the shell 24 and the slider 23 to move downward, and then driving the stress wave sensor 25 to get close to the rock surface, avoiding the impact of the uneven rock on the effective contact between the probe of the stress wave sensor 25 and the rock, and by separating the stress wave sensor 25 from the L-shaped plate 12 as a whole, the subsequent maintenance of the stress wave sensor 25 is facilitated.

[0028] The stress wave sensor 25 is arranged at the lower end of the shell 24. A Bluetooth communication unit 26 and a power supply unit 27 are respectively provided inside the shell 24. The card block 28 is located on the side wall of the shell 24. The card block 28 is fixedly installed with the shell 24 and is engaged with the card slot 22. By arranging the stress wave sensor 25, the stress wave of detonation in each hole can be detected, so that the blasting network in the remaining holes can be improved and optimized according to the detected stress wave, so that the stress wave can be more effectively applied in the rock, and the crushing efficiency of the ore can be improved. The optimized blasting network can further reduce the energy loss of the stress wave during the propagation process, increase the proportion of useful work, thereby reducing the consumption of explosives and improving the safety of operation. By accurately controlling the propagation range of the blasting vibration and the stress wave, the damage to the surrounding surrounding rock and filling body is reduced, the safety of the mine operation is improved, and the production adaptability is enhanced. The device can be applied to mines with different rock conditions and filling body types, has strong production adaptability and flexibility, and is more practical.

[0029] Working principle:

[0030] The first step is to open two circular grooves in the rock near the blasting network to be tested during use, which are engaged with the positioning pins 13. Then, the positioning pins 13 can be used to install the L-shaped plate 12 on the rock as a whole. Then, the shell 24 can be picked up and placed between the L-shaped plates 12 until the block 28 is located inside the slot 22. At this time, the slider 23 will be located inside the first slide groove 16. At this time, the screw rod 19 can be rotated to make the screw rod 19 and the transmission block 21 threadedly transmit. At this time, the transmission block 21 will slide downward in the second slide groove 17 and generate a radial force, thereby driving the block 28, the shell 24 and the slider 23 to move downward. At this time, the slider 23 will slide in the first slide groove 16 until the probe of the stress wave sensor 25 contacts the rock surface. Then, the staff can insert the baffle 15 into the square groove 14 to complete the limit of the stress wave sensor 25 to prevent the stress wave sensor 25 from falling from one side of the baffle 15 due to the vibration of the explosion.

[0031] In the second step, the fuse of one of the blasting networks can be first connected to the detonating head of the detonating device body 11 (the detonating device body 11 is composed of a detonating module, a Bluetooth communication module, a data processing module, a power module, and a user interface module, so that each module works together, so that the detonating device can effectively trigger the fuse, receive and process the data of the stress wave sensor 25). At this time, the detonating device body 11 can be turned on to detonate the fuse. The stress wave generated by the explosion will cause the entire ground to vibrate. At this time, the stress wave sensor 25 will perform detection and remotely transmit the data to the inside of the detonating device body 11 through the Bluetooth communication unit 26. Then the staff can adjust the blasting network in the remaining holes according to the previous explosion situation and stress wave data.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
