[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Reference Figure 1-3 A mine blasting charging device includes a support rod 1, which is composed of a first telescopic rod 11 and a second telescopic rod 12. The first telescopic rod 11 is slidably connected to the second telescopic rod 12 and is telescopically connected therebetween via a locking assembly 2. The other end of the second telescopic rod 12 is slidably connected to a support plate 3 and fixedly connected to a mounting tube 4.
[0021] A clamping assembly 5 is provided inside the installation tube 4 , and the clamping assembly 5 is used for filling explosives.
[0022] It should be added that a limiting groove is provided on the periphery of the second telescopic rod 12, and the support plate 3 slides with the second telescopic rod 12 through the limiting groove. The support plate 3 is attached to the outer wall of the blasting hole, supporting the support rod 1 to facilitate insertion into the installation tube 4, and anti-slip nails are also provided on the bottom surface of the support plate 3.
[0023] Furthermore, the locking assembly 2 includes a movable block 21, and the interior of the second telescopic rod 12 is slidably connected to the movable block 21 through a limiting groove 121. The end of the first telescopic rod 11 is fixedly connected to a screw rod 112 through a tapered portion 111, and the screw rod 112 is threadedly connected to the movable block 21.
[0024] Furthermore, it also includes a locking piece 22, which is a cylindrical structure, and a deformation groove 221 is provided on its periphery along the axis connecting the midpoint. The cone tip of the conical portion 111 is arranged near one end of the screw rod 112, and the locking piece 22 can be sleeved on the periphery of the conical portion 111 through the deformation groove 221.
[0025] In more detail, the movable block 21 contacts and pushes the locking member 22, and the other end of the locking member 22 contacts the end of the first telescopic rod 11. There are several anti-slip protrusions 222 located in the outer circumferential array of the locking member 22, and it presses against the inner wall of the second telescopic rod 12 through the anti-slip protrusions 222.
[0026] In specific operation, the movable block 21 slides with the second telescopic rod 12 through the limiting groove 121. When the first telescopic rod 11 is rotated, the movable block 21 is driven by the screw rod 112 to move, and at the same time, it contacts and pushes the locking member 22. The locking member 22 is sleeved on the outer periphery of the tapered portion 111 through the deformation groove 221, and the two ends of the locking member 22 can contact the movable block 21 and the end of the first telescopic rod 11, so as to achieve the effect of pressing the inner wall of the second telescopic rod 12 through the anti-slip protrusion 222.
[0027] After the two ends of the locking member 22 are tightly pressed against the movable block 21 and the end of the first telescopic rod 11, the first telescopic rod 11 will not be easily affected by the torsion and will not rotate freely with the second telescopic rod 12.
[0028] Of course, in order to better fix the first telescopic rod 11, a locking bolt can also be threadedly connected to the end of the second telescopic rod 12. One end of the locking bolt is fixedly connected to an anti-sliding block, which can be tightly pressed against the outer wall of the first telescopic rod 11 through the arc groove on the side.
[0029] It should be noted that the locking member 22 is preferably made of a deformable material such as rubber or plastic. When adjusting the length of the support rod 1, the first telescopic rod 11 can be pulled outward, and the locking member 22 is not affected by the movable block 21 and recovers its shape after being separated from the tapered portion 111.
[0030] In order to better fit the tapered portion 111, a guide slope is provided around the through hole on one side of the locking member 22 close to the tapered portion 111;
[0031] It is worth mentioning that the operation of locking the first telescopic rod 11 and the second telescopic rod 12 by the locking assembly 4 can refer to the adjustment structure of the punch-free telescopic rod in the prior art.
[0032] In general, the clamping assembly 5 includes an electric push rod 51, and the interior of the mounting cylinder 4 forms a mounting cavity through a partition. The electric push rod 51 is fixedly installed in the mounting cavity. The axial end of the electric push rod 51 passes through the partition and is fixedly connected to a fixing part 52. T-blocks 521 are provided on both sides of the fixing part 52 through guiding slopes.
[0033] Finally, a pair of clamping jaws 53 is also included. A slide groove 41 is provided at the bottom of the mounting tube 4. The pair of clamping jaws 53 are slidably connected in the slide groove 41 through grooves 531 on both sides, and T-slots 532 that cooperate with the T-block 521 are also provided on the opposite sides of the bottom of the pair of clamping jaws 53.
[0034] It should be added that a battery is also provided in the installation cavity, the battery is electrically connected to the electric push rod 51, and the electric push rod 51 is electrically connected to an external control device. The electric push rod 51 drives the fixing member 52 by the shaft end, and the T-block 521 and the T-slot 532 cooperate with each other to slide to drive the pair of clamping jaws 53 to move relative to each other.
[0035] The pair of clamping jaws 53 move relative to each other to clamp the explosive and place the explosive in the blasting hole.
[0036] Working method: When the length of the support rod 1 needs to be adjusted during operation, the first telescopic rod 11 is rotated, and the movable block 21 is driven by the screw rod 112 to move to the side away from the locking member 22. After the locking member 22 loses its resistance and disengages from the tapered portion 111, it disengages from the inner wall of the second telescopic rod 12, and the position between the first telescopic rod 11 and the second telescopic rod 12 can be adjusted;
[0037] After the position is determined, the first telescopic rod 11 is rotated in the opposite direction. The movable block 21 is driven by the screw rod 112 and moves in the opposite direction. The movable block 21 contacts and pushes the locking member 22. The locking member 22 is sleeved on the outer periphery of the tapered portion 111 through the deformation groove 221. The locking member 22 also presses against the inner wall of the second telescopic rod 12 through the anti-slip protrusion 222 on the outer periphery, thereby fixing the first telescopic rod 11.
[0038] Finally, the support plate 3 is in contact with the outer wall of the blasting hole to support the support rod 1, and the shaft end of the electric push rod drives the fixing part 52 to move. When the fixing part 52 moves, the pair of clamps 53 are driven to move relative to each other through the T-block 521 and the T-slot 532, and the explosives are clamped and installed by the pair of clamps 53.
[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
