Description

Technical Field

[0001] The utility model relates to the technical field of mineral blasting, in particular to a device for quickly arranging holes in bench blasting. Background Technique

[0002] In the battery field, the battery contains oxides such as lithium, nickel, cobalt, and manganese, and its raw materials are made from mineral materials such as lithium ore. In open-pit rock foundation pits, trench excavations, and mine mining, blasting is the most common and rapid technical means. In blasting, blasting construction requires high requirements for refinement and quantification. After the quantitative blasting design is completed, the designed blasting parameters need to be accurately and quickly fed back to the site for subsequent drilling construction.

[0003] Currently, in open-pit blasting projects, the multi-row hole arrangement is divided into three types: plum blossom shape, rectangle, and square. The on-site hole arrangement usually arranges the first hole according to the minimum resistance line in the blasting design specification, and then uses the previous hole as a reference object and the hole spacing and row spacing as standards, and uses tools such as tape measures and measuring tapes to arrange the second hole, and repeats alternately in turn until the hole arrangement of the entire blasting area is completed. In this process, each hole needs to be marked at the hole opening with paint, red flags or other markers, and it is carried out in the situation of at least two people, and the personnel operation efficiency is low. And when arranging multi-row blast holes, due to the lack of effective reference objects, it is very difficult to ensure that the rows of blast holes are parallel to each other, thus changing the hole pattern parameters, resulting in uneven distribution of explosive energy, generating large blocks or excessive fragmentation and other phenomena, thereby affecting the blasting effect.

[0006] Preferably, the two measuring rods are perpendicular to the vertical rod and parallel to the plane of the table board, the directions of the two measuring rods are on the same straight line, and the distances between the two measuring rods and the vertical rod are equal.

[0007] Preferably, legs are installed on the surface of the table board away from the vertical rod.

[0008] Preferably, the marking mechanism includes a paint can which is installed on the side of the tabletop away from the vertical rod. The paint can has a push switch and a spray nozzle. The spray nozzle is coaxial with the vertical rod and faces away from the tabletop. The push switch penetrates through the tabletop and is located on the surface of the tabletop.

[0009] Preferably, the height of the leg is greater than the height of the paint can.

[0019] Embodiment

[0020] Please refer to Figure 1 - Figure 2 , the present utility model provides a rapid hole layout device for bench blasting, which includes a table board 1. One side of the table board 1 is connected with a vertical rod 2. Measuring rods 3 are rotatably installed on both sides of the vertical rod 2 on the table board 1 at equal intervals. The connection points of the measuring rods 3, the vertical rod 2 and the table board 1 are located on a connection line. A marking mechanism is installed on the other side of the table board 1 and is coaxial with the vertical rod 2. A compass 8 is installed at the top of the vertical rod 2; in the present utility model, the table board 1 is placed corresponding to the ground. At this time, the two measuring rods 3 need to be parallel to the table board 1. First, place the table board 1 at the edge of the bench, unfold the measuring rods 3, adjust the device to be parallel to the bench edge, record the azimuth indicated by the compass 8, determine the distance between the bench edge and the first row of blast holes. The positions of the blast holes can be determined through the measuring rods 3 and the compass 8. Then, place the table board 1 above the position of the blast hole, and mark the position of the blast hole through the marking mechanism; taking the existing blast hole marking as a reference, determine the position of the second blast hole through the measuring rods 3 and the compass 8, move the table board 1 above the position of the second blast hole, and mark the position of the blast hole through the marking mechanism; repeat the above work to complete the marking work of the first row of blast holes. When arranging the second row of blast holes, only take the marking of the first row of blast holes as a reference, rotate the device according to the designed angle, and make the end of the measuring rod 3 correspond to the position of the first row of blast holes. The position of the first blast hole in the second row can be determined through the measuring rods 3 and the compass 8, and repeating the above operation can complete the bench blast hole layout work.

[0021] In the specific implementation manner, referring to Figure 1 , the two measuring rods 3 are perpendicular to the vertical rod 2 and parallel to the plane of the table board 1. The directions of the two measuring rods 3 are on the same straight line, and the distances between the two measuring rods 3 and the vertical rod 2 are equal. The measuring rod 3 has scales, which can measure the interval between two blast holes. When in use, the measuring rod 3 needs to be parallel to the table board 1 to accurately determine the interval between the blast holes. If there is an angle between the measuring rod 3 and the table board 1, it may cause the problem that the measured interval is smaller and the actual interval is larger.

[0022] In the specific implementation manner, referring to Figure 1, a leg 4 is installed on the side of the tabletop 1 away from the vertical rod 2. The vertical rod 2 on the tabletop 1 can be used to support the entire device, facilitating its placement on the ground when determining the accurate position of the blast hole.

[0023] In the specific implementation manner, refer to Figure 1 , the marking mechanism includes a paint can 5. The paint can 5 is installed on the side of the tabletop 1 away from the vertical rod 2. The paint can 5 has a pressing switch 7 and a spray nozzle 6. The spray nozzle 6 is coaxial with the vertical rod 2 and faces away from the tabletop 1. The pressing switch 7 penetrates through the tabletop 1 and is located on the surface of the tabletop 1. When the device determines the position of the next blast hole, at this time, the pressing switch 7 is squeezed, so that the paint in the paint can 5 is ejected through the spray nozzle 6 for marking. The paint can 5 is a spraying can in the prior art.

[0024] In the specific implementation manner, refer to Figure 1 , the height of the leg 4 is greater than the height of the paint can 5. After the leg 4 supports the tabletop 1, there needs to be an installation space for the paint can 5 below the tabletop 1. Therefore, when the leg 4 is long enough, the paint can 5 can be suspended without contacting the ground.

[0025] In the specific implementation manner, refer to Figure 1 , the vertical rod 2 is a telescopic rod; the measuring rod 3 is a telescopic rod. The measuring rod 3 can adjust the length of the measuring rod 3 by telescoping and change the length measured by the measuring rod 3.

[0026] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
