Description

Technical Field

[0001] The present invention relates to blasting engineering, and in particular to a recyclable fast-assisted uncoupled charging system and a charging method. Background Art

[0002] Currently, deep metal mining and some tunnel excavation are primarily carried out using the drilling and blasting method. During blasting operations in mines and heading tunnels, smooth blasting with uncoupled intermittent charging is used for holes surrounding the tunnels to ensure a regular tunnel profile and uniform rock fragmentation after blasting. After drilling, holes must be cleaned and charged promptly. Manual intermittent charging is not only time-consuming and labor-intensive, but also difficult to control the spacing between charge rolls. To save time, on-site workers often resort to continuous charging, which compromises the blasted cross-section. Based on this, many researchers have proposed disposable sleeve charging, which improves the efficiency of on-site intermittent charging while avoiding hole blockage. However, disposable intermittent charging sleeves increase mining costs, resulting in limited practical application. Further improvements have been made to charging equipment, including the use of mechanized recyclable charging devices, which reduce the need for disposable materials and promote sustainable resource utilization. However, the loading process of mechanical recyclable devices is prone to sparks, posing a safety hazard. Consequently, uncoupled intermittent charging devices have not been widely adopted.

[0056] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0057] In this application, the end close to the bottom of the blasthole is defined as the proximal end, and the end held and operated by the operator is defined as the distal end.

[0058] like Figure 1-7As shown, an embodiment of the present invention provides a recyclable fast-assisted uncoupled charging system, including a charging device and an auxiliary plate 40, wherein the charging device includes a kit 10 and a slide 20, wherein the kit 10 is a semicircular ring. In this application, a semicircular ring refers to a spatial geometric body with a semicircular cross-sectional pattern, which is stretched in a direction perpendicular to the cross-sectional pattern, and the stretching direction is the axial direction of the semicircular ring. A first arc-shaped cavity 11 is provided on the kit 10, and the first arc-shaped cavity 11 passes through the kit 10 along the axial direction of the kit 10. The first arc-shaped cavity 11 is also semicircular. It can be understood that the central angle corresponding to the first arc-shaped cavity 11 is smaller than the central angle corresponding to the kit 10. The area where the kit 10 bends inward is the charging area for placing the medicine roll. Specifically, the first arc-shaped cavity 11 divides the kit 10 into an inner side and an outer side along the diameter direction, wherein the area half-enclosed by the inner side is the charging area.

[0059] The aforementioned sliding member 20 is also a semi-circular ring. The sliding member 20 is disposed in the first arc-shaped cavity 11 and can rotate around the axial direction of the first arc-shaped cavity 11 .

[0060] The charging device has a first state and a second state. When the charging device is in the first state, the slider 20 is located within the first arcuate cavity 11, allowing the charging area to be loaded with a drug roll. When the charging device is in the second state, the slider 20 slides out of the first arcuate cavity 11 and cooperates with the sleeve 10 to form a cylindrical structure that completely surrounds the charging area. At this point, the charging device can rotate in any direction about the axial direction of the sleeve 10 without the drug roll falling. The charging device is then placed in the blasthole and rotated 180 degrees so that the slider 20 is located below the sleeve 10. The slider 20 is then slid into the first arcuate cavity 11. The drug roll, having lost its support, slides out of the sleeve 10, completing the placement of the drug roll. After the placement of the drug roll is complete, the charging device is removed from the blasthole. In this application, the charging device is used to assist in the placement of the drug roll, ensuring that the placement of the drug roll complies with operating procedures while also preventing sparks from the drug roll during placement, which could pose a safety hazard.

[0061] Furthermore, a first sector piece 12 and a second sector piece 21 are respectively provided at the same end of the sleeve 10 and the slide 20. In this embodiment, the first sector piece 12 and the second sector piece 21 are provided at the proximal ends of the sleeve 10 and the slide 20. Specifically, a plurality of first sector pieces 12 are provided, and the plurality of first sector pieces 12 are provided on the end surface of the sleeve 10 and are provided on the side close to the center of the circle. The first sector piece 12 is triangular in shape and is rotatably connected to the sleeve 10. A threading hole 13 is provided on the inner side of the sleeve 10, and the threading hole 13 is connected to the first arc-shaped cavity 11. There is one threading hole 13, and the threading hole 13 is located on the sleeve 10 and away from the sliding end. The first sector piece 12 is acted upon by a first force, which drives the end of the first sector piece 12 away from the sleeve 10 to retract in a direction away from the center of the circle of the sleeve 10.

[0062] The aforementioned second sector piece 21 is hinged to the end face of the slide 20. Similarly, the second sector piece 21 is hinged to the end face of the slide 20. The second sector piece 21 is acted upon by a second force, driving the second sector piece 21 away from one end of the slide 20 to retract in a direction away from the center of the kit 10.

[0063] The charging device also includes a pull rope, which includes a first pull rope 14 fixed to the inner side of the first sector-shaped piece 12 and a second pull rope 22 fixed to the inner side of the second sector-shaped piece 21. One end of the first pull rope 14 is fixed to a first sector-shaped piece 12 farthest from the threading hole 13, and the other end passes through the threading hole 13 to form a free end. At the same time, the first pull rope 14 is also connected to each first sector-shaped piece 12 passed by. When the automatic end of the first pull rope 14 is pulled, the first sector-shaped piece 12 is retracted inward.

[0064] Similarly, in the first state, one end of the second drawstring 22 is fixed to the slider 20, with the fixing point away from the slid-out end of the sleeve 10. The other end of the second drawstring 22 forms a free end, which is connected to the free end of the first drawstring 14. The second drawstring 22 is connected to each of the second sector pieces 21. When the slider 20 slides out of the sleeve 10 (i.e., when switching from the first state to the second state), the first sector pieces 12 and the second sector pieces 21 are retracted inward.

[0065] In this embodiment, a first elastic unit 15 is connected to the first sector 12. One end of the first elastic unit 15 is connected to the outer side of the first sector 12 and the other end is connected to the outer side of the sleeve 10. The first elastic unit 15 provides a first force for the first sector 12. Similarly, a second elastic unit 23 is connected to the second sector 21. One end of the second elastic unit 23 is connected to the outer side of the second sector 21 and the other end is connected to the outer side of the slider 20. The second elastic unit 23 provides a second force for the second sector 21. Preferably, the first elastic element and the second elastic element are both elastic ropes.

[0066] In this embodiment, when the first sector piece 12 and the second sector piece 21 are only acted upon by the first force and the second force, in order to avoid the first sector piece 12 and the second sector piece 21 from opening too much, which may cause the charging device to be obstructed during the process of being placed into the blast hole, a right-angle 90-degree hinge is used for connection when the first sector piece 12 and the second sector piece 21 are hinged to the kit 10 or the slide 20. Compared with the traditional flat-angle hinge, the right-angle 90-degree hinge can limit the maximum opening angle of the first sector piece 12 and the second sector piece 21 to a right angle. Since the right-angle 90-degree hinge is a prior art, its structure will not be described in detail here. When using the right-angle 90-degree hinge, the rotation axis of the hinge is toward the side close to the center of the kit 10. At this time, due to the limiting effect of the right-angle 90-degree hinge, under the action of the first elastic unit 15 and the second elastic unit 23, the first sector piece 12 and the second sector piece 21 fixed on the hinge can be opened to a maximum angle of 90 degrees. At this time, the direction of the first sector piece 12 is parallel to the axial direction.

[0067] In the present application, by arranging the first sector piece 12 and the second sector piece 21 at one end of the kit 10 and the slide 20, when the slide 20 and the kit 10 rotate relative to each other, the first sector piece 12 and the second sector piece 21 rotate and the proximal ends approach to form a cone-shaped structure. When the charging device is placed in the blast hole, the gravel in the blast hole is pushed to both sides, preventing the charging device from being unable to reach the bottom of the hole due to obstruction by the gravel.

[0068] Preferably, a plurality of fixing plates 16 are provided on the inner wall of the kit 10, and the plurality of fixing plates 16 are arranged along the axial direction of the kit 10. Each fixing plate 16 can slide in the axial direction of the kit 10 and be fixed at any position. By controlling the distance and the total number between the fixing plates 16, staggered loading of medicine can be achieved, and the length of the medicine roll and the amount of medicine roll used can be effectively controlled.

[0069] In the present application, a structure is provided that enables the fixing plate 16 to both slide along the axial direction and be fixed on the kit 10. It should be clarified that structures that satisfy the requirements that the fixing plate 16 can both be slidably set on the kit 10 and be fixed relative to the kit 10 are all within the scope of protection of the present application.

[0070] A guide groove 161 is provided inside the sleeve 10, running parallel to the axial direction of the sleeve 10. Positioning teeth 162 are located on both sidewalls of the guide groove 161. These teeth 162 consist of multiple semicircular structures connected end to end. A slider 163 is positioned within the guide groove 161 and engages with the serrations on either side of the guide groove 161. The slider 163 is herringbone-shaped and has two open feet 164. The fixed plate 16 is mounted perpendicular to the slider 163. To move the slider 163, simply pull it to a desired position.

[0071] In some embodiments of the present application, anti-skid bumps 17 are further provided on both sides of the fixing plate 16 , and the anti-skid bumps 17 are used to assist the fixing plate 16 in fixing the medicine roll.

[0072] Since the environment inside the blasthole is relatively complex and the blasthole is relatively deep, when using the recyclable fast-assisted uncoupled charging system, it should also be avoided that there is water accumulation in the blasthole or too much resistance hinders the rotation of the charging device. For this reason, an auxiliary plate 40 is also provided in this application for different usage environments.

[0073] The auxiliary plate 40 is used to be inserted into the first arcuate cavity 11 when the charging device is in the second state. As can be understood, the auxiliary plate 40 is also semi-circular in shape and is provided with a second arcuate cavity 41. The second arcuate cavity 41 penetrates the auxiliary plate 40 along the axial direction of the auxiliary plate 40 and separates the auxiliary plate 40 into an inner layer and an outer layer. The outer layer is provided with a first through hole 42, and a plurality of first through holes 42 are provided along the axial direction of the auxiliary plate 40. The plurality of first through holes 42 communicate with the second arcuate cavity 41. An operation hole 43 is provided at the end of the auxiliary plate 40. The operation hole 43 is located on the inner layer of the auxiliary plate 40 and communicates with the second arcuate cavity 41.

[0074] A second through hole 18 is provided on the outer layer of the sleeve 10, and the second through hole 18 is communicated with the first through hole 42. Preferably, when the auxiliary plate 40 is inserted into the first arc-shaped cavity 11, the first through hole 42 and the second through hole 18 are aligned.

[0075] Preferably, a receiving groove 47 is further provided at the proximal end of the auxiliary plate 40. The receiving groove 47 is arranged along the radial direction of the auxiliary plate 40. The receiving groove 47 is used to accommodate the filter plug 44. The shape of the receiving groove 47 is adapted to the shape of the filter plug 44. Specifically, the filter plug 44 includes an arc-shaped body, which has the same shape as the second arc-shaped cavity 41. A filter screen is provided on the arc-shaped body. When the filter plug 44 is plugged into the auxiliary plate 40, the filter screen is located in the axial direction of the second arc-shaped cavity 41.

[0076] In the present application, by inserting the auxiliary plate 40 into the kit 10 and connecting the pumping equipment via the operating hole 43 on the auxiliary plate 40, the water in the bottom of the hole can be pumped out, providing a relatively dry environment for the charging device, thereby preventing the accumulated water from soaking the medicine roll and causing the medicine roll to become ineffective.

[0077] Furthermore, in order to address the problem of high friction in the blast hole and difficulty in rotating the charging device, the present application adds other components on the basis of the auxiliary plate 40 to complete the lubrication of the blast hole.

[0078] Specifically, the filter plug 44 on the auxiliary plate 40 is removed and a sealing plug 45 is inserted in the same position. The sealing plug 45 serves to seal the proximal end of the second arcuate cavity 41. A waterproof fabric 46 is disposed within the second arcuate cavity 41 and can be deployed along the arc of the second arcuate cavity 41. When deployed, the waterproof fabric 46 prevents the lubricating oil injected from the operating hole 43 from flowing into the first through-hole 42. Instead, it allows the lubricating oil to move evenly along the axial direction of the auxiliary plate 40, thereby quickly flowing into the proximal end of the kit 10. When the lubricating oil reaches the proximal end of the kit 10, the waterproof fabric 46 is retracted, connecting the first through-hole 42 with the second through-hole 18, and the lubricating oil flows out of the charging device through the second through-hole 18.

[0079] In this embodiment, the waterproof fabric 46 is provided to prevent the lubricating oil from leaking from the first through hole 42 near the distal end during the oil filling process, thereby preventing the lubricating oil from having insufficient kinetic energy to move to the proximal end of the sleeve 10 .

[0080] Preferably, to facilitate the unfolding and retracting of the waterproof fabric 46, a clip 461 is provided at one end of the fabric 46, and a handle is provided at the other end. Correspondingly, a slide 462 is provided within the second arcuate cavity 41 of the auxiliary plate 40, engaging with the clip 461. The slide 462 is arranged axially along the auxiliary plate 40. The slide 462 restricts the clip 461 from disengaging in the arc direction of the second arcuate cavity 41, but does not restrict the clip 461 from sliding axially within the slide 462.

[0081] When the waterproof cloth 46 needs to be used, the clamping member 461 is inserted into the sliding groove 462 , and the handle is pulled along the arc direction of the second arc-shaped cavity 41 to open the waterproof cloth 46 .

[0082] Preferably, a limiting pin hole is provided on the sealing pin 45 for the handle to be inserted into when it slides to the end of the arc line of the second arc-shaped cavity 41 .

[0083] Based on the aforementioned charging system, the present application further provides a charging method for charging a blasthole, comprising the following steps:

[0084] The first step is to select medicine rolls and charging devices of appropriate lengths according to different working conditions, adjust the distance between adjacent fixed plates 16 according to the length of each medicine roll, place several medicine rolls into the charging area, rotate the slider 20, and switch the charging device from the first state to the second state; during the charging process, adjust the distance between adjacent fixed plates 16 so that the adjacent fixed plates 16 limit the position of the medicine rolls in the axial direction of the kit 10.

[0085] In the second step, the charging device is inserted into the blast hole and flipped 180 degrees along the axial direction of the kit 10 so that the slide 20 is located below the kit 10, and the slide 20 is retracted into the first arc-shaped cavity 11. At this time, the charging device is switched from the second state to the first state again, and the medicine roll that loses its support falls from the kit 10 and falls into the blast hole.

[0086] The third step is to withdraw the charging device from the blast hole after the cartridge falls, completing the placement of the cartridge.

[0087] The charging method provided by the present application can ensure that each charge roll falls into the designated position in the blasthole during the charging process, avoiding the position misalignment of the charge rolls. At the same time, the present application is a purely mechanical structure, which does not generate sparks during the charging process and has good safety.

[0088] The present application also provides a second charging method for charging a powder roll when drainage of the blasthole is required, comprising the following steps:

[0089] The first step is to select medicine rolls and charging devices of appropriate lengths according to different working conditions, adjust the distance between adjacent fixed plates 16 according to the length of each medicine roll, place several medicine rolls into the charging area, rotate the slider 20, and switch the charging device from the first state to the second state; during the charging process, adjust the distance between adjacent fixed plates 16 so that the adjacent fixed plates 16 limit the position of the medicine rolls in the axial direction of the kit 10.

[0090] The second step is to insert the auxiliary plate 40 into the first arc-shaped cavity 11 and connect the operating hole 43 to the pumping equipment;

[0091] Preferably, before inserting the auxiliary plate 40 into the first arc-shaped cavity 11 , the filter plug 44 is inserted into the auxiliary plate 40 to block large particles of impurities and prevent the large particles of impurities from clogging the second arc-shaped cavity 41 and causing poor water flow.

[0092] Preferably, the distal end of the second arc-shaped groove is sealed, and the sealing can be performed according to the materials available on site, such as by using a cloth strip or the like to seal the distal end of the second arc-shaped groove.

[0098] In the second step, the auxiliary plate 40 is inserted into the first arc-shaped cavity 11 , and the operation hole 43 is connected to the oil injection device, and the waterproof cloth 46 is opened to block the connection between the operation hole 43 and the first through hole 42 .

[0099] Before the auxiliary plate 40 is inserted into the first arc-shaped cavity 11 , the sealing pin 45 is inserted into the auxiliary plate 40 , and then the auxiliary plate 40 is inserted into the first arc-shaped cavity 11 .

[0100] The third step is to place the retrievable quick-assisted uncoupled charging system in the blasthole, open the oil injection device, inject a sufficient amount of lubricating oil into the second arc-shaped cavity 41 through the operating hole 43, and then retract the waterproof cloth 46. The lubricating oil in the second arc-shaped cavity 41 flows out of the charging device through the first through hole 42 and the second through hole 18 to lubricate the blasthole.

[0101] In the fourth step, after lubrication is completed, the auxiliary plate 40 is pulled out, the kit 10 is flipped 180 degrees along the axial direction so that the slide 20 is located below the kit 10, and the slide 20 is retracted into the first arc-shaped cavity 11. At this time, the charging device switches from the second state to the first state again, and the medicine roll that loses its support falls from the kit 10 and falls into the blast hole.

[0102] The fifth step is to remove the charging device from the blast hole after the powder roll falls, and complete the placement of the powder roll.

[0103] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
