Description

Technical Field

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

[0002] At present, deep metal mining and some tunnel excavation are mostly carried out by drilling and blasting. During the blasting construction of mine stopes and tunnels, in order to make the tunnels regular and the ore and rock blocks uniform after blasting, smooth blasting and uncoupled interval charging are used for the holes around the tunnels. The holes must be cleaned and charged in time after drilling. Manual interval charging is not only time-consuming and labor-intensive, but also difficult to control the interval distance of the charge rolls. In order to save time, on-site workers usually adopt continuous charging, which affects the blasting section forming effect. On this basis, many scholars have proposed disposable sleeve charging, which improves the efficiency of on-site interval charging while avoiding hole blocking; however, the disposable interval charging sleeve increases the economic cost of mines to a certain extent, and is rarely used in mines. On this basis, scholars have improved the charging equipment and adopted a mechanized recyclable charging device, which reduces the demand for disposable materials to a certain extent and is conducive to the sustainable use of resources. However, the filling process of the mechanical recyclable device is prone to sparks, forming a safety hazard, so the uncoupled interval charging device has not been widely used.

[0056] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, 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 body. In the present application, a semicircular ring body refers to a spatial geometric body formed by stretching in a direction perpendicular to the cross section with a semicircular cross-sectional pattern, and the stretching direction is the axial direction of the semicircular ring body. A first arc-shaped cavity 11 is provided on the kit 10, and the first arc-shaped cavity 11 penetrates the kit 10 along the axial direction of the kit 10. The first arc-shaped cavity 11 is also semicircular, and it can be understood that the center angle corresponding to the first arc-shaped cavity 11 is smaller than the center angle corresponding to the kit 10. The area where the kit 10 bends inward is a charging area for placing medicine rolls. Specifically, the first arc-shaped cavity 11 separates 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 semicircular ring. The sliding member 20 is disposed in the first arc-shaped cavity 11 , and the sliding member 20 can rotate around the axial direction of the first arc-shaped cavity 11 .

[0060] The charge device has a first state and a second state, wherein when the charge device is in the first state, the slide 20 is located in the first arc-shaped cavity 11, and at this time, medicine rolls can be loaded into the charge area; when the charge device is in the second state, the slide 20 slides out of the first arc-shaped cavity 11, and cooperates with the set 10 to form a cylindrical structure, which fully surrounds the charge area, and at this time, the charge device can rotate in any direction around the axial direction of the set 10, and the medicine roll does not fall. Then the charge device is placed in the blast hole, and the charge device is rotated 180 degrees so that the slide 20 is located below the set 10, and the slide 20 is slid into the first arc-shaped cavity 11. At this time, the medicine roll slides out of the set 10 due to the loss of support, and the placement of the medicine roll is completed. After the placement of the medicine roll is completed, the charge device is withdrawn from the blast hole. In the present application, the charge device is used to assist the placement of the medicine roll, which can not only ensure that the placement of the medicine roll complies with the operating procedures, but also avoid the sparks generated by the medicine roll during the placement to form a safety hazard.

[0061] Further, the first fan-shaped piece 12 and the second fan-shaped piece 21 are respectively arranged at the same end of the set 10 and the slide 20. In this embodiment, the first fan-shaped piece 12 and the second fan-shaped piece 21 are arranged at the proximal ends of the set 10 and the slide 20. Specifically, there are a plurality of first fan-shaped pieces 12, which are arranged on the end surface of the set 10 and arranged on the side close to the center of the circle. The first fan-shaped piece 12 is triangular in shape, and the first fan-shaped piece 12 is rotatably connected to the set 10. A threading hole 13 is arranged on the inner side of the set 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 set 10 and is far away from the sliding end. The first fan-shaped piece 12 is acted upon by the first force, driving the end of the first fan-shaped piece 12 away from the set 10 to close in the direction away from the center of the circle of the set 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 end of the second sector piece 21 away from the slide 20 to retract in a direction away from the center of the set 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 fan-shaped piece 12 and a second pull rope 22 fixed to the inner side of the second fan-shaped piece 21. One end of the first pull rope 14 is fixed to a first fan-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 of the first fan-shaped pieces 12 passing through. When the automatic end of the first pull rope 14 is pulled, the first fan-shaped pieces 12 are retracted inward.

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

[0065] In this embodiment, the first sector piece 12 is connected to a first elastic unit 15, one end of the first elastic unit 15 is connected to the outside of the first sector piece 12, and the other end is connected to the outside of the set 10, and the first elastic unit 15 provides a first force for the first sector piece 12. Similarly, the second sector piece 21 is connected to a second elastic unit 23, one end of the second elastic unit 23 is connected to the outside of the second sector piece 21, and the other end is connected to the outside of the slider 20, and the second elastic unit 23 provides a second force for the second sector piece 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 in the blast hole, a right-angle 90-degree hinge is used to connect the first sector piece 12 and the second sector piece 21 to the kit 10 or the slide 20 when they are hinged. 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 the right-angle 90-degree hinge is used, the rotation axis of the hinge is directed to 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 fan-shaped piece 12 and the second fan-shaped piece 21 fixed on the hinge can be opened to a maximum angle of 90 degrees. At this time, the direction of the first fan-shaped piece 12 is parallel to the axial direction.

[0067] In the present application, by setting the first fan-shaped piece 12 and the second fan-shaped 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 fan-shaped piece 12 and the second fan-shaped 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, the interval 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] The present application provides a structure 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 allow the fixing plate 16 to both be slidably set on the kit 10 and be fixed relative to the kit 10 are all within the protection scope of the present application.

[0070] A guide groove 161 is provided on the inner side of the sleeve 10, and the guide groove 161 is provided parallel to the axial direction of the sleeve 10. Limiting teeth 162 are provided on the two side walls of the guide groove 161. The limiting teeth 162 are composed of a plurality of semicircular structures connected end to end. A sliding member 163 is provided in the guide groove 161, and the sliding member 163 is engaged with the saw teeth on both sides of the guide groove 161. The sliding member 163 is in a herringbone shape and has two open bottom feet 164. The fixing plate 16 is vertically provided on the sliding member 163. When the sliding member 163 needs to be moved, the sliding member 163 is pulled to move to a predetermined position.

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

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

[0073] The auxiliary plate 40 is used to be inserted into the first arc-shaped cavity 11 when the charge device is in the second state. It can be understood that the auxiliary plate 40 is also in the shape of a semicircular ring, and a second arc-shaped cavity 41 is opened on the auxiliary plate 40. The second arc-shaped cavity 41 penetrates the auxiliary plate 40 along the axial direction of the auxiliary plate 40, and the second arc-shaped cavity 41 separates the auxiliary plate 40 into an inner layer and an outer layer. Among them, a first through hole 42 is provided on the outer layer, 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 are connected to the second arc-shaped 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 the operation hole 43 is connected to the second arc-shaped 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, and 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, and the arc-shaped body 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 fail.

[0077] Furthermore, in order to address the problem of high friction in the blast hole and difficulty in rotating the charge 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 the sealing plug 45 is inserted at the same position. The function of the sealing plug 45 is to close the proximal end of the second arc-shaped cavity 41. The waterproof cloth 46 is arranged in the second arc-shaped cavity 41, and the waterproof cloth 46 can be unfolded along the arc direction of the second arc-shaped cavity 41. When the waterproof cloth 46 is unfolded, the waterproof cloth 46 prevents the lubricating oil injected from the operation hole 43 from flowing into the first through hole 42, but makes the lubricating oil move evenly along the axial direction of the auxiliary plate 40, so that the lubricating oil flows into the proximal end of the kit 10 as soon as possible. When the lubricating oil flows to the proximal end of the kit 10, the waterproof cloth 46 is retracted, and the first through hole 42 and the second through hole 18 are connected, and the lubricating oil flows out of the charging device through the second through hole 18.

[0079] In this embodiment, the waterproof cloth 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 kit 10 .

[0080] Preferably, in order to realize the unfolding and reeling of the waterproof cloth 46, a clamping member 461 is provided at one end of the waterproof cloth 46, and a handle is provided at the other end. Correspondingly, a slide groove 462 clamped with the clamping member 461 is also provided in the second arc cavity 41 of the auxiliary plate 40, and the slide groove 462 is arranged along the axial direction of the auxiliary plate 40. The slide groove 462 restricts the clamping member 461 from disengaging in the arc direction of the second arc cavity 41, but does not restrict the axial sliding of the clamping member 461 in the slide groove 462.

[0081] When the waterproof cloth 46 is needed, 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 also 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, put a number of 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 set 10 so that the slide 20 is located below the set 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 set 10 and falls into the blast hole.

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

[0087] The charging method provided by the present application can ensure that each charge roll falls into a designated position in the blast hole during the charging process, thereby preventing the position of the charge roll from being misplaced. At the same time, the present application is a purely mechanical structure, and will not generate sparks during the charging process, which is relatively safe.

[0088] The present application also provides a second charging method for charging a charge roll when drainage is required in a blasthole, 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, put a number of 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 closed, and the closing can be performed according to the materials on site, such as using a cloth strip to close the distal end of the second arc-shaped groove.

[0093] The third step is to place the recyclable quick-assisted uncoupled charging system in the blast hole, turn on the pumping equipment, and drain the accumulated water in the blast hole.

[0094] In the fourth step, after the pumping is completed, the auxiliary plate 40 is pulled out of the charging device, the set 10 is flipped 180 degrees along the axial direction, so that the slide 20 is located below the set 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 set 10 and falls into the blast hole.

[0095] The fifth step is to withdraw the charging device from the blast hole after the charge roll falls, thus completing the placement of the charge roll.

[0096] The present application also provides a third charging method for loading a charge roll when lubrication is required in a blast hole, comprising the following steps:

[0097] 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, put 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.

[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 with the oil injection device, and the waterproof cloth 46 is spread to cut off 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 recyclable quick-assisted uncoupled charging system in the blast hole, turn on the oil injection device, inject a sufficient amount of lubricating oil into the second arc cavity 41 through the operating hole 43, and then close the waterproof cloth 46. The lubricating oil in the second arc cavity 41 flows out of the charging device through the first through hole 42 and the second through hole 18 to lubricate the blast hole;

[0101] In the fourth step, after lubrication is completed, the auxiliary plate 40 is pulled out, the set 10 is flipped 180 degrees along the axial direction, so that the slide 20 is located below the set 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 set 10 and falls into the borehole.

[0102] The fifth step is to withdraw the charging device from the blast hole after the charge roll falls, thus completing the placement of the charge 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 the scope of protection of the present invention.
