Description

Technical Field

[0001] The utility model relates to the technical field of blasting charging, in particular to a segmented charging device for blasting construction. Background Art

[0002] Traditional rock slope blasting and excavation has a series of problems such as high blasting vibration intensity, long blasting flying stone distance, and large blasting slag block diameter. Therefore, people began to use the construction method of interval charging and precise control of blasting to carry out blasting.

[0003] The method of precise control of blasting construction by interval charging on slopes under complex environments has the following characteristics. First, Midas GTS NX software is used to conduct overall modeling and analysis of the slope construction blasting area and its adjacent buildings, calculate blasting parameters in advance and simulate the blasting process, which can effectively evaluate the safety of the blasting construction process. At the same time, the high-precision control of digital detonator hole-by-hole detonation technology can accurately control the detonation time, effectively reduce the explosion disturbance amplitude, and more effectively protect the safety of surrounding buildings and structures; secondly, the use of gas spacers for segmented charging avoids excessive crushing of the surrounding rock near the blasthole, improves the effective utilization rate of explosive blasting energy, thereby reducing blasting costs and controlling blasting hazards; at the same time, drones are used for blasting clearance and inspection: to assist manual blasting safety alerts, reduce the input of alert personnel, shorten the alert clearance time, and reduce blasting safety risks.

[0004] The patent with announcement number CN217358294U discloses "a charging device for blasting construction, belonging to the field of tunnel blasting technology. A charging device for blasting construction includes a charging cartridge. The utility model can push the plug plate to move under the action of the sealing plate when the uppermost movable plate moves, thereby allowing the inclined plug plate to be inserted into the soil, thereby ensuring the stability of the charging cartridge in the soil and preventing the charging cartridge from falling out from the top of the tunnel during blasting."

[0005] With regard to the above-mentioned related technologies, the inventor believes that they use multiple movable plates and other components to load the explosives in sections, and drive the plug plate to move and insert into the soil by turning the crank to ensure the stability of the charge cartridge in the soil. However, since the threaded rod and the crank are arranged on the edge of the charge cartridge and are small in size, after people turn the crank several times, the movable plate and the sealing plate can only move a short distance, which results in a long time to turn the crank, affecting the construction efficiency.

[0022] The following is combined with Figure 1-3 The utility model is described in further detail.

[0023] Reference Figure 1 The utility model embodiment discloses a segmented charging device for blasting construction, including a segmented charging cartridge 1, a plug plate 11 installed at one end of the segmented charging cartridge 1, a crank 12 installed at the other end of the segmented charging cartridge 1 and used for people to shake to insert the plug plate 11 into the soil, and an acceleration mechanism installed at one side of the segmented charging cartridge 1 and used to accelerate the rotation of the crank 12. After people shake the crank 12, the plug plate 11 can be driven to move and insert the plug plate 11 into the surrounding soil. This is a public technology and will not be described in detail here.

[0024] Reference Figure 1 A door panel 13 is rotatably provided on one side of the segmented cartridge 1 for people to load the explosives into the segmented cartridge 1 in sections. People can open the door panel 13 to load the explosives into the segmented cartridge 1 in sections. The explosives loaded in sections can be precisely controlled to blast at intervals in blasting areas such as slopes. For the purpose of public technology, the segmented cartridge 1, the plug plate 11, the crank 12 and the door panel 13 constitute an existing charging device for blasting construction, and its internal structure and principle have been disclosed, so no further elaboration is required here.

[0025] Reference Figure 1-3The acceleration mechanism includes a small gear 2 fixed on the outer wall of the crank 12, a large gear 21 meshingly connected to one side of the small gear 2 and having a diameter larger than the small gear 2, a rotating rod 22 fixed in the large gear 21, and a crank handle 23 fixed on one side of the rotating rod 22. The small gear 2 and the large gear 21 are both located outside the segmented cartridge 1, so that the gear 2 and the large gear 21 can rotate outside the segmented cartridge 1.

[0026] People can shake the crank 23 to drive the rotating rod 22 to rotate. After the rotating rod 22 rotates, it will drive the large gear 21 to rotate. Since the diameter of the large gear 21 is larger than the diameter of the small gear 2, the small gear 2 will rotate several circles after the large gear 2 rotates one circle, thereby accelerating the rotation of the small gear 2, thereby accelerating the rotation of the crank 12 in the small gear 2, shortening the time people spend turning the crank 12.

[0027] Reference Figure 1-2 A rotating hole 14 is formed on the outer wall of one end of the segmented drug cartridge 1, and the end of the rotating rod 22 away from the crank handle 23 is inserted into the rotating hole 14. The segmented drug cartridge 1 can limit the inserted rotating rod 22 through the rotating hole 14, making it convenient for one end of the rotating rod 22 to rotate in the rotating hole 14.

[0028] Reference Figure 1-2 The stabilizing mechanism for improving the rotational stability of the swivel rod 22 is provided at one end of the swivel rod 22. The stabilizing mechanism includes a stabilizing plate 3 rotatably arranged on the outer wall of one end of the swivel rod 22, and a plurality of suction cups 31 fixedly arranged on one side of the stabilizing plate 3. The adsorption end of the suction cup 31 cooperates and abuts with the outer wall of the segmented drug cartridge 1. A swivel ring 32 is fixedly arranged on the outer wall of one end of the swivel rod 22. The swivel ring 32 is rotatably connected in the stabilizing plate 3. The swivel ring 32 can connect the swivel rod 22 and the stabilizing plate 3 so that the swivel rod 22 and the stabilizing plate 3 will not fall off. The swivel ring 32 can be in a circular ring shape. The suction cup 31 can be adsorbed on the outer wall of the segmented drug cartridge 1 to support and fix components such as the stabilizing plate 3. The stabilizing plate 3 can support and limit components such as the swivel rod 22 to improve the stability of components such as the swivel rod 22 during rotation.

[0029] Reference Figure 1 A plug rod 4 inserted into the soil is fixedly arranged at the middle part of one end of the segmented cartridge 1 close to the plug plate 11, and a plurality of barbed rods 41 inserted into the soil are fixedly arranged on the outer wall of the plug rod 4. People can insert the plug rod 4 and the barbed rods 41 into the soil to support and limit the device in the soil, and the barbed rods 41 can limit the device during blasting, so that the device is not easy to fall out from the top of the blasting area such as the slope.

[0030] The implementation principle of the segmented charging device for blasting construction in the embodiment of the utility model is:

[0031] When in use, people can open the door panel 13 to load the explosives into the segmented cartridge 1 in sections, then close the door panel 13 and use the insertion rod 4 and the barbed rod 41 to insert the segmented cartridge 1 into the blast hole soil in the blasting area such as the slope, then people can insert one end of the rotating rod 22 into the rotating hole 14 of the segmented cartridge 1, and make the large gear 21 mesh with the small gear 2. At this time, as the rotating rod 22 is inserted, the moved suction cup 31 will be adsorbed on the outer wall of the segmented cartridge 1;

[0032] At this time, people can shake the crank 23 to drive the rotating rod 22 to rotate. After the rotating rod 22 rotates, it will drive the large gear 21 to rotate. Since the diameter of the large gear 21 is larger than the diameter of the small gear 2, the small gear 2 will rotate several times after the large gear 21 rotates one circle, so as to accelerate the rotation of the small gear 2 and the crank 12, shortening the time for people to rotate the crank 12. After the crank 12 rotates, it will drive the plugging plate 11 to move and insert into the surrounding soil, and cooperate with the plugging of the plugging rod 4 and the barbed rod 41 to improve the stability of the device in the soil.

[0033] Then people can pull out the rotating rod 22 from the rotating hole 14 and remove the suction cup 31 to dismantle the rotating rod 22, the crank handle 23, the large gear 21 and the balancing mechanism and other components for reuse.
