Description

Technical Field

[0001] The utility model relates to the technical field of mine blasting tools. More specifically, the utility model relates to a pre-buried device for a blasting structure in mine engineering blasting. Background Technique

[0002] Blasting mining is a mining method that uses explosives to break rocks or ores, generally used in mining and tunnel excavation. During the blasting mining process, it is necessary to accurately calculate the amount and placement location of explosives to ensure safe and effective mining operations. At the same time, it is also necessary to strictly abide by relevant safety regulations and operating procedures to ensure the safety of personnel and equipment.

[0003] When operating personnel conduct mine engineering blasting, they need to first install a pre-buried device in the blasting hole, and then place the detonator inside the pre-buried device. In the actual use of the existing pre-buried device, although it has the basic installation function, in the existing pre-buried device, the sleeve is generally fixedly connected to the closed cover through threads, but the fixing effect of this connection is poor, and the closed cover is very easy to detach from the inside of the sleeve under the impact of the detonator explosion, which will cause part of the energy generated by the explosion to leak from one end of the sleeve, affecting the final blasting effect. Therefore, it needs to be improved. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a pre-buried device for a blasting structure in mine engineering blasting, which has the advantages of being closed and stable.

[0005] To achieve the above object, the utility model provides the following technical solution: A pre-buried device for a blasting structure in mine engineering blasting, including a sleeve, a threaded sleeve is fixedly sleeved on the right side of the outer surface of the sleeve, a connecting line is fixedly connected to the outer surface of the threaded sleeve, the other end of the connecting line is fixedly connected to a closed cover, a clamping block is fixedly connected to the inner surface of the closed cover, the inner surface size of the clamping block is the same as the outer surface size of the sleeve, and a socket block is fixedly sleeved on the outer surface of the closed cover, and the shape of the socket block is hexagonal.

[0006] As a preferred technical solution of the utility model, a tapered sleeve is fixedly sleeved on the outer surface of the sleeve on the left side of the threaded sleeve, and a movable piece is fixedly connected to the left side of the outer surface of the sleeve.

[0007] As a preferred technical solution of the utility model, a hollow tube is movably sleeved on the inner surface of the sleeve, the right end of the hollow tube penetrates through the sleeve and extends to the right side of the sleeve, a fixing block is fixedly sleeved on the left side of the inner surface of the hollow tube, a limiting strip is fixedly connected to the outer surface of the hollow tube, and the outer surface of the limiting strip is movably connected to the inner surface of the sleeve.

[0008] As an optimal technical solution of the present invention, the right surface of the fixed block is fixedly connected to a No. 1 hexagonal block located inside the hollow tube, and the inner surface of the hollow tube is movably connected to a movable tube located on the right side of the No. 1 hexagonal block.

[0009] As a preferred technical solution of the present invention, the outer surface of the movable tube is movably connected to the limiting sleeve, and the outer surface of the limiting sleeve is fixedly sleeved with the inner surface of the hollow tube.

[0010] As an optimal technical solution of the present invention, the left surface of the movable tube is fixedly connected to a No. 2 hexagonal block, the outer surface of the No. 2 hexagonal block is hinged to a No. 2 connecting rod, the other end of the No. 2 connecting rod is hinged to a No. 1 connecting rod, and the other end of the No. 1 connecting rod is hinged to the outer surface of the No. 1 hexagonal block.

[0011] As a preferred technical solution of the present invention, a pull ring located on the right side of the sleeve is fixedly sleeved on the outer surface of the hollow tube, and the pull ring has a circular shape.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model provides a sleeve, a threaded sleeve, a closing cover, a sleeve block and a clamping block. First, the operator makes the inner surface of the closing cover and the outer surface of the threaded sleeve engage with each other, so that the clamping block comes into contact with the threaded sleeve. Then, when the operator rotates the sleeve block as a whole, the threaded sleeve and the closing cover are threadedly sleeved, and the clamping block, the sleeve block and the closing cover move to the left. During this process, the threaded sleeve and the sleeve squeeze the clamping block, so that the clamping block gradually deforms and embeds into the outer surface of the sleeve, thereby improving the stability of the connection between the closing cover and the sleeve.

[0014] 2. The utility model is provided with a cone sleeve, a movable piece, a No. 1 connecting rod, a No. 2 connecting rod and a movable tube. When the hollow tube contacts the right side of the inner surface of the casing, the operator pushes the movable tube to move to the left. As the movable tube and the No. 2 hexagonal block move, the No. 2 connecting rod rotates. At the same time, the No. 1 connecting rod also starts to rotate under the drive of the No. 2 connecting rod. During the rotation of the No. 1 and No. 2 connecting rods, the No. 1 and No. 2 connecting rods will support the movable piece and eventually cause the movable piece to warp outward and embed into the blasting hole. At this time, the entire casing will be fixed in the blasting hole under the joint action of the cone sleeve and the movable piece, ensuring that the entire casing will not shake.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] As Figures 1 to 7 shown, the present utility model provides a pre-buried device for a blasting structure used in mine engineering blasting, including a sleeve 1. A threaded sleeve 2 is fixedly sleeved on the right side of the outer surface of the sleeve 1. A connecting wire 3 is fixedly connected to the outer surface of the threaded sleeve 2. The other end of the connecting wire 3 is fixedly connected to a closing cover 4. A clamping block 6 is fixedly connected to the inner surface of the closing cover 4. The inner surface size of the clamping block 6 is the same as the outer surface size of the sleeve 1. A socket block 5 is fixedly sleeved on the outer surface of the closing cover 4. The outer shape of the socket block 5 is hexagonal.

[0025] The outer surface of the threaded sleeve 2 and the inner surface of the closing cover 4 can be threadedly sleeved. When the operator sleeved the closing cover 4 on the outer surface of the sleeve 1 and made the inner surface of the closing cover 4 and the outer surface of the threaded sleeve 2 mesh with each other, the clamping block 6 would come into contact with the threaded sleeve 2. And when the operator began to rotate the socket block 5 as a whole, the socket block 5 and the closing cover 4 as a whole would start to move to the left. At this time, the clamping block 6 would be squeezed by the threaded sleeve 2 during the leftward movement, and finally the clamping block 6 would be deformed and embedded into the outer surface of the sleeve 1.

[0026] The outer surface of the sleeve 1 is fixedly sleeved with a tapered sleeve 7 located on the left side of the threaded sleeve 2 , and the left side of the outer surface of the sleeve 1 is fixedly connected with a movable piece 8 .

[0027] When the operator inserts the entire casing 1 into the reserved blasting hole and makes the cone sleeve 7 contact the blasting hole, the cone sleeve 7 will initially limit the entire casing 1.

[0028] Among them, the inner surface of the sleeve 1 is movably connected with a hollow tube 9, the right end of the hollow tube 9 passes through the sleeve 1 and extends to the right side of the sleeve 1, the left side of the inner surface of the hollow tube 9 is fixedly connected with a fixed block 10, the outer surface of the hollow tube 9 is fixedly connected with a limiting strip 11, and the outer surface of the limiting strip 11 is movably connected to the inner surface of the sleeve 1.

[0029] The design of the hollow tube 9 and the limiting strip 11 enables an operator to pull the hollow tube 9 out of the interior of the sleeve 1 as a whole.

[0030] The right surface of the fixed block 10 is fixedly connected to a No. 1 hexagonal block 12 located inside the hollow tube 9 , and the inner surface of the hollow tube 9 is movably connected to a movable tube 16 located on the right side of the No. 1 hexagonal block 12 .

[0031] The movable tube 16 can move left and right along the inner surface of the hollow tube 9 .

[0032] The outer surface of the movable tube 16 is movably connected to the limiting sleeve 17 , and the outer surface of the limiting sleeve 17 is fixedly sleeved with the inner surface of the hollow tube 9 .

[0033] The design of the limiting sleeve 17 plays a role in limiting the movable tube 16 .

[0034] Among them, the left surface of the movable tube 16 is fixedly connected to the No. 2 hexagonal block 15, the outer surface of the No. 2 hexagonal block 15 is hinged to the No. 2 connecting rod 14, the other end of the No. 2 connecting rod 14 is hinged to the No. 1 connecting rod 13, and the other end of the No. 1 connecting rod 13 is hinged to the outer surface of the No. 1 hexagonal block 12.

[0035] When the movable tube 16 and the No. 1 hexagonal block 12 move to the left, the No. 1 connecting rod 13 starts to rotate, and at the same time, the No. 2 connecting rod 14 also rotates under the drive of the No. 1 connecting rod 13.

[0036] The outer surface of the hollow tube 9 is fixedly sleeved with a pull ring 18 located on the right side of the sleeve 1, and the pull ring 18 has a circular shape.

[0037] The design of the pull ring 18 makes it easy for the operator to pull the hollow tube 9 out of the interior of the sleeve 1 as a whole.

[0038] The working principle and use process of this utility model:

[0039] First, the operator inserts the entire sleeve 1 into the blasting hole and makes the tapered sleeve 7 contact the inner wall of the blasting hole. Then, the operator inserts the entire hollow tube 9 into the inside of the sleeve 1 until the entire hollow tube 9 moves to the leftmost end inside the sleeve 1. Then, the operator pushes the movable tube 16 and the second hexagonal block 15 to the left. At this time, the second connecting rod 14 will rotate under the drive of the second hexagonal block 15, and the other end of the second connecting rod 14 will drive the first connecting rod 13, causing the first connecting rod 13 to also start rotating. During this process, the outer ends of the first connecting rod 13 and the second connecting rod 14 will squeeze the movable piece 8. Eventually, the movable piece 8 will warp outward from the sleeve 1 under the extrusion of the first connecting rod 13 and the second connecting rod 14. At this time, the movable piece 8 will be embedded into the blasting hole. Thus, the entire sleeve 1 will be fixed in the blasting hole under the combined action of the tapered sleeve 7 and the movable piece 8.

[0040] Then, the operator withdraws the entire hollow tube 9 and places the detonator inside the sleeve 1. Subsequently, the operator threads the inner surface of the closing cover 4 onto the outer surface of the threaded sleeve 2. At this time, the clamping block 6 will contact the sleeve 1 and the threaded sleeve 2. Then, the operator rotates the socket block 5 and the entire closing cover 4, causing the clamping block 6 to start moving to the left. At this time, under the extrusion of the sleeve 1 and the threaded sleeve 2, the inner surface of the clamping block 6 will gradually be embedded into the outer surface of the sleeve 1. This ensures the sealing stability of the inside of the sleeve 1 by the entire closing cover 4.
