Description

Technical Field

[0001] The present application belongs to the technical field of plugging mine blastholes, and in particular relates to a mine blasthole rapid plugging device. Background Art

[0002] A blasthole is a hole drilled on the blasted object (such as rock or ore body) to load explosives for blasting. According to its depth and diameter, it can be divided into three categories: shallow hole, medium-deep hole and deep hole. The depth, diameter and direction of the blasthole all affect the blasting effect.

[0003] The existing blasthole plugging construction process is: use large tank truck equipment to transport shock-absorbing materials, fill the shock-absorbing materials into the pit, and then cover them with sand. This construction process is labor-intensive and time-consuming and labor-intensive during plugging, which greatly reduces the efficiency of blasthole plugging. In addition, the existing solution will not achieve the ideal blasting effect due to insufficient top resistance.

[0004] Therefore, we propose a mine blasthole rapid plugging device to solve the above problems. Utility Model Content

[0007] The cam is connected with the first end of the support frame, and the cam is connected with the second end of the support frame by the hinge mechanism, and the cam is connected with the hinge mechanism one end of the support frame by the chest that the support frame is provided with.

[0008] Preferably, the bottom surfaces of the three second rotating seats are commonly fixedly connected to a fixing block, the upper surface of the fixing block is fixedly connected to the bottom surface of the limiting tube, and a connecting piece is provided below the fixing block.

[0009] Preferably, four bolts are provided below the connecting piece, and the top end of each bolt passes through the connecting piece and is threadedly connected to the inner wall of the fixing block.

[0010] Preferably, a conical block is provided below the connecting member, and the upper surface of the conical block contacts the bottom surface of the connecting member.

[0011] Preferably, four threaded wires are provided above the connecting piece, and the bottom end of each threaded wire passes through the connecting piece and is threadedly connected to the inner wall of the conical block.

[0012] Preferably, four explosive packs are provided on the outside of the connecting piece, and the side surfaces of each group of explosive packs close to each other are fixedly connected to the outer surface of the connecting piece.

[0013] Preferably, a hook is provided above the lifting block, and the bottom surface of the hook is fixedly connected to the upper surface of the lifting block.

[0014] In summary, the technical effects and advantages of this application are:

[0015] Three sets of outward-expandable support arms are provided to adapt to holes of different sizes. The inverted teeth are used to increase the resistance of the equipment. The support rod is inserted into the interior of the limiting tube. When the soil is filled above, the lifting block will be pressed down by gravity. At this time, the lifting block will press down the support rod and insert the support rod into the interior of the limiting tube. The support rod is a one-way design, which can only be pressed down but not pulled up. Therefore, when blasting, it can greatly block the impact force of the blasting from directly above, and then allow the blasting energy to spread from the bottom to the surrounding area, exerting the maximum power and achieving the ideal blasting effect.

DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-4 A mine blasthole rapid plugging device includes a lifting block 1, the bottom surface of the lifting block 1 is fixedly connected to three first rotating seats 2, the inner wall of each first rotating seat 2 is rotatably connected to a hinged upper arm 3, and a hook 19 is provided above the lifting block 1. The bottom surface of the hook 19 is fixedly connected to the upper surface of the lifting block 1. The hook 19 can be used to lift the equipment, making it convenient to lower it at a uniform speed using mechanical equipment.

[0023] One end of each articulated upper arm 3 away from the first rotating seat 2 is rotatably connected to the articulated lower arm 4, and one end of each articulated lower arm 4 away from the articulated upper arm 3 is rotatably connected to the second rotating seat 5. The bottom surfaces of the three second rotating seats 5 are commonly fixedly connected to a fixed block 13, and the upper surface of the fixed block 13 is fixedly connected to the bottom surface of the limiting tube 8. A connecting piece 14 is provided below the fixed block 13. The fixed block 13 is utilized to connect the extended structure, and the connection with the limiting tube 8 can play a supporting and limiting role.

[0024] Each articulated upper arm 3 is rotatably connected to a resistance block 6 at one end away from the first rotating seat 2. The outer surface of each resistance block 6 is fixedly connected to a number of inverted teeth 7. Four bolts 17 are provided under the connecting member 14. The top of each bolt 17 passes through the connecting member 14 and is threadedly connected to the inner wall of the fixed block 13. The connecting member 14 is used to connect blasting equipment, and the four bolts 17 are used to firmly connect the connecting member 14 to the fixed block 13.

[0025] The bottom surface of the lifting block 1 is fixedly connected to a support rod 9, the outer surface of the support rod 9 is slidably connected to a limiting tube 8, the inner wall of the support rod 9 is fixedly connected to ten springs 10, and a conical block 16 is arranged below the connecting piece 14. The upper surface of the conical block 16 contacts the bottom surface of the connecting piece 14, and the conical block 16 plays the role of load-bearing. The pointed design facilitates the equipment below.

[0026] The ends of each group of springs 10 that are away from each other are fixedly connected with a latch 11, and the outer surface of each latch 11 is slidably connected to the inner wall of the support rod 9. Four threaded wires 18 are provided above the connecting piece 14, and the bottom end of each threaded wire 18 passes through the connecting piece 14 and is threadedly connected to the inner wall of the conical block 16. Using the four threaded wires 18, the conical block 16 can be firmly installed under the connecting piece 14.

[0027] The upper and bottom surfaces of each latch 11 are fixedly connected to a limit block 12, and the outer surface of each limit block 12 is slidably connected to the inner wall of the support rod 9. Four explosive packs 15 are provided on the outer side of the connecting piece 14, and the side surfaces of each group of explosive packs 15 close to each other are fixedly connected to the outer surface of the connecting piece 14. The four explosive packs 15 are installed on the side surface of the connecting piece 14. The size of the explosive pack 15 is smaller than that of the conical block 16, and it is not easy to touch the hole wall and fall when lowered.

[0028] The working principle of the present invention is as follows: when in use, first use the sling of the mechanical equipment to lift the hook 19, and then use the mechanical equipment to quickly and evenly lower the lowest point of the blasthole, at this time release the hook 19, retract the sling of the mechanical equipment, and at this time fill the blasthole with soil, under the influence of the gravity of the soil, the hoisting block 1 will be pressed downward, and at this time, under the downward pressure of the hoisting block 1, the three groups of support arms can be extended to allow the resistance block 6 to contact the inner wall of the blasthole and continue to embed into the inner wall of the blasthole. Specifically, the hinged relationship between the upper arm 3 and the lower arm 4, as well as the relationship between the rotation connection between the upper arm 3 and the first rotating seat 2, and the relationship between the rotation connection between the lower arm 4 and the second rotating seat 5 are achieved, so that the upper arm 3 and the lower arm 4 are both rotated outward to achieve the purpose of pushing the resistance block 6 out, and the inverted teeth 7 are used to further increase the upward resistance;

[0029] At this time, the support rod 9 is inserted into the interior of the limiting tube 8. When the soil is filled above, the lifting block 1 will be pressed down by gravity, and at this time the lifting block 1 will press the support rod 9 downward, and the support rod 9 will be inserted into the interior of the limiting tube 8. The design of the latch teeth 11 and the limiting tube 8 are both at an oblique angle, and the use of the spring 10 can absorb the force, so that the latch teeth 11 can be retreated into the interior of the support rod 9 under the downward force, and then gradually get stuck in the limiting hole of the limiting tube 8. The support rod 9 is a one-way design, which can only be pressed downward but not pulled upward. Therefore, when blasting, it can greatly block the impact force of the blasting from directly above, and then allow the blasting energy to spread from the bottom to the surrounding area, exerting the maximum power and achieving an ideal blasting effect.
