Detailed implementation manners

[0020] The following further describes the present invention in detail in conjunction with the drawings and specific implementation manners, but does not limit the protection scope and application scope of the present invention.

[0021] Embodiment 1 A deep-hole blasting explosive mounting plate that is convenient for taking out, referring to Figures 1 - 8 as shown, includes a tripod 1; a winding device is provided on the tripod 1; It also includes a wire rope 2, a connecting rod 3, an airbag 4, an air pipe 5, a cylinder 6, a sealing cover 7, a first annular plate 8, a supporting bracket 9, a magnet 10 and an annular iron sheet 11; the winding device arranged on the tripod 1 winds the wire rope 2; the other end of the wire rope 2 is fixedly connected with the connecting rod 3; the connecting rod 3 is fixedly connected with the airbag 4, and the airbag 4 is composed of two upper and lower expansion parts with the same size; the airbag 4 is communicated with the air pipe 5; a cylinder 6 is arranged below the tripod 1, and the cylinder 6 is used for loading explosives and the cylinder 6 filled with explosives is placed into the blasting hole; a sealing cover 7 is installed on the cylinder 6, the cross section of the sealing cover 7 is U-shaped, and the upper part of the sealing cover 7 is obliquely arranged upward towards the outer side surface of the cylinder 6; two first annular plates 8 distributed up and down are fixedly connected inside the sealing cover 7, and the upper surfaces of all the first annular plates 8 are obliquely arranged downward towards the center of the sealing cover 7; the inner bottom of the sealing cover 7 is connected with the supporting bracket 9; four magnets 10 are fixedly connected to the airbag 4; an annular iron sheet 11 is fixedly connected to the bottom surface of the first annular plate 8 close to the supporting bracket 9, and the bottom surface of the annular iron sheet 11 is flush with the bottom surface of the first annular plate 8.

[0022] A plurality of arc-shaped parts 41 are arranged on the airbag 4, and an annular groove 81 is formed at the bottom of the first annular plate 8. After the airbag 4 expands, the arc-shaped parts 41 also expand and are clamped into the annular groove 81, thereby improving the stability of the airbag 4 when lifting the cylinder 6, the sealing cover 7 and the first annular plate 8.

[0023] The supporting bracket 9 is provided with a hollow structure, so that the fallen soil fragments can pass through the supporting bracket 9 through the hollow structure and fall onto the inner bottom of the sealing cover 7, thereby avoiding the fallen soil fragments blocking the supporting bracket 9 and affecting the supporting effect of the supporting bracket 9 on the connecting rod 3.

[0024] A support rod 91 is arranged on the supporting bracket 9, and the supporting bracket 9 is separated from the inner bottom surface of the sealing cover 7 through the support rod 91, avoiding the problem that soil fragments accumulate on the inner bottom surface of the sealing cover 7, resulting in the blocking of the supporting bracket 9 and affecting the supporting effect of the supporting bracket 9 on the connecting rod 3.

[0025] Four extension plates 92 distributed in an annular array are arranged on the supporting bracket 9, and the connecting rod 3 is guided into the inside of the supporting bracket 9 through the extension plates 92 to ensure that the connecting rod 3 is located at the middle position of the supporting bracket 9.

[0026] It also includes a first spring telescopic rod 13 and a second annular plate 14; two straight grooves 31 are formed on the connecting rod 3, and a first spring telescopic rod 13 is fixedly connected in each straight groove 31; the telescopic parts of the first spring telescopic rods 13 are fixedly connected with the second annular plate 14, and the second annular plate 14 is fixedly connected with the lower end of the airbag 4.

[0027] It also includes a gravity ball 15; a spherical bottom shell 32 is arranged on the connecting rod 3, and the gravity ball 15 is placed inside the spherical bottom shell 32.

[0028] It further includes an annular plate III 16; the annular plate III 16 is fixedly connected inside the sealing cover 7.

[0029] It further includes a retaining piece 17; the retaining piece 17 is fixedly connected to the sealing cover 7, and four arc-shaped pieces 171 are arranged on the retaining piece 17 in an annular array distribution, and all the arc-shaped pieces 171 and the retaining piece 17 together form a conical shape.

[0030] It further includes support bars 12; a plurality of four support bars 12 are fixedly connected to the airbag 4.

[0031] The working mode of the above embodiment is as follows: It should be noted that: there are safety hazards for live equipment to enter the blasting area, which is not conducive to the safe progress of blasting operations. Therefore, the devices entering the hole cannot be live. Since the hole depth is a fixed depth, the length of the rope lowered can be used to know whether the connecting rod 3 and the airbag 4 have descended to the bottom position of the hole.

[0032] Explosive placement work: Manually place the calculated explosives into the cylinder 6, and then connect the sealing cover 7 to the cylinder 6 with bolts so that the cylinder 6 is sealed by the sealing cover 7 to prevent the soil on the inner wall of the hole from falling into the inside of the cylinder 6 during the lowering process, which may affect the subsequent explosive performance. After the cylinder 6 is sealed by the sealing cover 7, manually insert the connecting rod 3 and the airbag 4 into the sealing cover 7 so that the spherical bottom shell 32 contacts the support bracket 9. Then, control the external pump to pump air into the air pipe 5 through the connected hose, so that the air entering the air pipe 5 is pumped into the airbag 4, causing the airbag 4 to expand. During the expansion of the airbag 4, the two expanded parts are respectively located below the two first annular plates 8. After the airbag 4 expands, it fits against the inner side surface of the sealing cover 7. At this time, the two first annular plates 8 clamp the expanded airbag 4, so that the airbag 4 can drive the cylinder 6 and the sealing cover 7 to move. Considering that the amount of explosives during deep-hole blasting is between 17 kg and 25 kg, only relying on the expanded airbag 4 to drive the cylinder 6 and the sealing cover 7 to move, there is a problem that the expanded airbag 4 may slip out between the two first annular plates 8. Therefore, when the airbag 4 expands, the lower expanded part of the airbag 4 drives the magnet 10 to gradually approach the annular iron sheet 11 on the lower first annular plate 8. When the airbag 4 is fully expanded, all the magnets 10 on the airbag 4 are adsorbed to the annular iron sheet 11 on the lower first annular plate 8, thereby enhancing the support stability between the airbag 4 and the lower first annular plate 8. Moreover, when the airbag 4 expands, the arc part 41 on the airbag 4 also expands and is embedded in the annular groove 81. By embedding the expanded arc part 41 into the annular groove 81, the support stability between the airbag 4 and the lower first annular plate 8 is further improved. And a third annular plate 16 is provided below the lower first annular plate 8. When the airbag 4 between the third annular plate 16 and the lower first annular plate 8 expands, the third annular plate 16 and the lower first annular plate 8 clamp the expanded airbag 4, making the arc part 41 fit more stably with the annular groove 81 and preventing the arc part 41 from slipping out of the annular groove 81. Then, control the steel wire rope 2 to pull the connecting rod 3 so that the airbag 4 drives the cylinder 6 and the sealing cover 7 to move above the hole. Then, control the winding device on the tripod 1 to lower the steel wire rope 2, so that the connecting rod 3, the airbag 4, the air pipe 5, the cylinder 6, the sealing cover 7 and their related components move synchronously downward along the hole. When the cylinder 6 and the sealing cover 7 reach the bottom of the hole, stop. Then, control the external pump to suck the air inside the airbag 4 through the air pipe 5, causing the airbag 4 to contract. At this time, pull the steel wire rope 2 through the winding device on the tripod 1, so that the connecting rod 3, the airbag 4, the air pipe 5 and their related components move synchronously upward above the hole, completing the explosive placement work.

[0033] Explosive extraction work: Considering that when it is necessary to reduce the amount of explosives for blasting work, since the hole is relatively deep and it is not convenient to extract the explosives in the hole, currently, usually the hole and the explosives in the hole are all abandoned, and then a new hole is drilled beside the previous hole, and then the amount of explosives designed later is placed in the hole. This method has a relatively high cost of explosive waste and also requires drilling a new hole, wasting time. Therefore, manually move the tripod 1 so that the steel wire rope 2, the connecting rod 3, and the airbag 4 initially in a contracted state are located directly above the hole. Subsequently, control the winding device on the tripod 1 to lower the steel wire rope 2, so that the connecting rod 3 and the airbag 4 move downward along the hole, and the connecting rod 3 and the airbag 4 move into the sealing cover 7. However, during this process, since it is impossible to observe the inside of the hole, it is impossible to determine whether the connecting rod 3 and the airbag 4 are aligned with the center position of the sealing cover 7, nor can it be determined whether the two expansion parts of the airbag 4 are aligned with the lower surface positions of the two annular plates 8. Therefore, the upper part of the sealing cover 7 is inclined upward on the outer side of the inclined cylinder 6. When the connecting rod 3 and the airbag 4 move downward and contact the edge of the sealing cover 7, the connecting rod 3 and the airbag 4 slide downward along the edge of the sealing cover 7 to the surface of the upper annular plate 8. And the upper annular plate 8 is inclined downward toward the center of the sealing cover 7. The connecting rod 3 and the airbag 4 continue to slide downward along the surface of the upper annular plate 8. The connecting rod 3 is guided into the bearing bracket 9 through the extension plate 92 to ensure that the connecting rod 3 is located in the middle of the bearing bracket 9 and slides onto the bearing bracket 9. The spherical bottom shell 32 is supported by the bearing bracket 9, thereby ensuring that the connecting rod 3 and the airbag 4 are located at the center position of the sealing cover 7. However, since it is impossible to observe the inside of the hole, the connecting rod 3 may be skewed at this time, resulting in the expansion part of the airbag 4 not being stuck into the lower side of the corresponding annular plate 8, causing the cylinder 6 and the sealing cover 7 to not be able to be taken out. Therefore, a gravity ball 15 is placed in the spherical bottom shell 32 to keep the connecting rod 3 and the airbag 4 always in a vertical state. When the length of the steel wire rope 2 is lowered to the same length as the depth of the hole, the worker only needs to pull the steel wire rope 2 up and down, so that the steel wire rope 2 drives the connecting rod 3 and the airbag 4 to move up and down reciprocally, which can ensure to the greatest extent that the connecting rod 3 and the airbag 4 are vertically supported on the bearing bracket 9. Subsequently, control the external pump to inflate the airbag 4 through the air pipe 5 so that the sealing cover 7 and all the annular plates 8 cooperate to clamp the inflated airbag 4. Then control the winding device on the tripod 1 to wind up the steel wire rope 2, so that the steel wire rope 2 pulls the connecting rod 3, the airbag 4, the air pipe 5, the cylinder 6, the sealing cover 7 and their related components upward to above the hole. Subsequently, the external pump sucks the air inside the airbag 4 through the air pipe 5 to make the airbag 4 contract. Then the worker removes the cylinder 6 and the sealing cover 7, adjusts the amount of explosives in the cylinder 6, and the extraction method is simple and convenient, without wasting explosives or drilling additional holes.

[0034] Considering that during the time when the cylinder 6 and the sealing cover 7 are located at the inner bottom of the hole, soil fragments, gravel, etc. on the inner wall surface of the hole will fall downward onto the sealing cover 7, causing the support bracket 9 to be blocked, thus affecting the support of the connecting rod 3 by the support bracket 9. Therefore, the support bracket 9 is set to be hollow, so that the fallen soil fragments and gravel will fall through the hollow structure of the support bracket 9 onto the inner bottom surface of the sealing cover 7. At the same time, a support rod 91 is provided at the bottom of the support bracket 9, separating a space between the support bracket 9 and the inner bottom surface of the sealing cover 7, preventing a large amount of soil fragments and gravel from falling on the inner bottom surface of the sealing cover 7 and blocking the support bracket 9, which affects the support of the connecting rod 3 by the support bracket 9. It is also considered that if the cylinder 6 and the sealing cover 7 stay in the hole for a long time, a large amount of soil fragments and gravel will accumulate in the sealing cover 7, affecting the subsequent removal work. Therefore, by providing a baffle 17 on the sealing cover 7, and four arc-shaped pieces 171 are provided on the baffle 17. All the arc-shaped pieces 171 and the baffle 17 together form a conical shape, so that the fallen soil fragments will move along the conical surface towards the edge, preventing the soil fragments from falling into the sealing cover 7, and thus ensuring the normal progress of the subsequent removal work. Considering that the airbag 4 in the contracted state is in a deflated state, the arc-shaped piece 171 will block the airbag 4 in the contracted state. Therefore, four support strips 12 are provided on the airbag 4, and the support strips 12 increase the hardness of the airbag 4 in the deflated state. Together with the gravity ball 15 in the spherical bottom shell 32, the airbag 4 in the contracted state can smoothly pass through the arc-shaped piece 171.

[0035] Moreover, when the steel wire rope 2 drives the connecting rod 3 and the airbag 4 to move downward, if soil adheres to the surface of the magnet 10, affecting the subsequent adsorption effect between the magnet 10 and the annular iron sheet 11. Therefore, by providing a first spring telescopic rod 13 and a second annular plate 14, when the airbag 4 is in the contracted state, the first spring telescopic rod 13 is always in the extended state, so that the second annular plate 14 continuously presses against the bottom of the airbag 4, causing the two expansion parts of the airbag 4 to be squeezed together, and the magnet 10 is located between the two expansion parts. Therefore, the magnet 10 is blocked by the two expansion parts, thus preventing soil from adhering to the surface of the magnet 10.

[0036] Embodiment 2 On the basis of Embodiment 1, with reference to Figure 3 as shown, it further includes a second spring telescopic rod 18, a circular arc chassis 19 and spikes 20; a second spring telescopic rod 18 is fixedly connected to the bottom of the cylinder 6; the telescopic part of the second spring telescopic rod 18 is fixedly connected to the circular arc chassis 19; four spikes 20 are fixedly connected to the bottom of the cylinder 6 in a circular array distribution, and four circular holes 191 are formed in the circular arc chassis 19 in a circular array distribution, and all the circular holes 191 are located directly below the corresponding spikes 20.

[0037] The following is the working mode of the above embodiment: Considering that when the cylinder 6 and the sealing cover 7 move to the bottom of the hole, it is impossible to ensure that the cylinder 6 and the sealing cover 7 are vertically placed, thus affecting the subsequent removal work. Therefore, when the cylinder 6 and the sealing cover 7 move to the bottom of the hole, the arc chassis 19 contacts the bottom of the hole first. Since there is explosive in the cylinder 6, the cylinder 6 has a large weight. The cylinder 6 squeezes the second spring telescopic rod 18 to contract, while the arc chassis 19 is restricted by the bottom of the hole and cannot move. Therefore, the cylinder 6 drives the spike 20 to gradually move downward, so that the spike 20 passes through the round hole 191 and pierces into the inner bottom surface of the hole. By piercing the spike 20 into the inner bottom of the hole, it is ensured that the cylinder 6 can be vertically placed at the bottom of the hole, which is convenient for the subsequent removal work.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
