Description

Technical Field

[0001] This utility model relates to the field of vibration monitoring technology, and in particular to a vibration monitoring device for mining. Background Technology

[0002] A mine refers to an independent production and operation unit that extracts ore within a defined mining boundary. A mine mainly includes one or more mining workshops (also known as pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants).

[0003] During blasting and excavation operations in mining areas, varying degrees of vibration will occur. To ensure safety, it is necessary to monitor the vibration intensity signal in the mining area in real time. However, existing vibration monitoring devices are prone to misalignment and displacement due to vibration in the mining area, which affects the accuracy of vibration monitoring. Utility Model Content

[0004] This invention proposes a vibration monitoring device for mines, which solves the problem in the prior art that the monitoring equipment is easily displaced and shifted due to vibration in the mining area, thus affecting the accuracy of vibration monitoring.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A vibration monitoring device for mining includes a main body, which has a shell, a vibration sensor module and a signal transmission module inside the shell, and also includes four fixing components, which are symmetrically installed at the four corners of the outer surface of the main body.

[0007] The fixing component includes a mounting base and an insertion rod. The mounting base is mounted on the outer shell of the main body, and the insertion rod is mounted vertically on the mounting base.

[0008] Furthermore, the bottom end of the insertion rod is fitted with a downward-facing conical head.

[0009] Furthermore, the insertion rod is a hollow cylindrical shape, and two symmetrical holes are opened on the outer surface of the insertion rod, with two retractable fixed protrusions arranged in the two holes.

[0010] Furthermore, each of the fixed protrusions is slidably installed in the hole on the insertion rod, a mounting piece is fixedly attached to the outer surface of each fixed protrusion, and a spring is sleeved on the outer surface of each fixed protrusion. The first end of the spring is connected to the mounting piece, and the second end of the spring is connected to the inner surface of the insertion rod.

[0011] An installation bearing seat is installed inside the insertion rod, and a shaped column is rotatably installed inside the installation bearing seat. The horizontal cross-section of the shaped column is circular, and two symmetrical arc-shaped concave portions are provided on both sides of the circle. The end of the fixed protrusion near the shaped column is a spherical surface.

[0012] Furthermore, each of the irregularly shaped columns is provided with a torsion assembly at its top. The torsion assembly includes a temporary fixing plate and a handwheel. The temporary fixing plate is fixed to the top of the irregularly shaped column, and the handwheel is fixed to the top of the temporary fixing plate.

[0013] Furthermore, the fixing component also includes a temporary positioning component, which includes a positioning plate and an elastic telescopic rod. Two elastic telescopic rods are provided, which are arranged opposite to each other. The telescopic end of each elastic telescopic rod is connected to a positioning plate. The two positioning plates are arranged opposite to each other, and the temporary fixing piece is located between the two positioning plates.

[0014] Furthermore, both positioning plates are provided with embedding grooves that match the two ends of the temporary fixing piece.

[0015] Furthermore, a handle is provided on the side of the main body shell, and a top cover is detachably provided on the top of the main body shell.

[0016] The positive effects of this invention are as follows: In the initial state, the spherical ends of the two fixed protrusions abut against the arc-shaped concave part of the irregular column. At this time, the fixed protrusions do not protrude from the holes of the insertion rod. When the handwheel drives the irregular column to rotate, the fixed protrusions leave the arc-shaped concave part of the irregular column and then slide to the outside of the arc-shaped concave part on the irregular column. At this time, the radius of the fixed protrusions contacting the irregular column becomes larger, thus pushing the fixed protrusions outward. The fixed protrusions compress the spring through the mounting plate, and the fixed protrusions move laterally and insert into the mineral soil, further enhancing stability and achieving dual fixation in both vertical and horizontal directions, which greatly improves the stability of the vibration monitoring device.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Combination Figure 1-3 As shown, a vibration monitoring device for mining includes a body 1, which has a shell containing a vibration sensor module and a signal transmission module. It also includes four fixing components, which are symmetrically installed at the four corners of the outer surface of the body 1.

[0032] The fixing assembly includes a mounting base 4 and an insertion rod 5. The mounting base 4 is mounted on the outer shell of the main body 1, and the insertion rod 5 is mounted vertically on the mounting base 4.

[0033] The bottom end of the insertion rod 5 is fitted with a downward-facing conical head 6.

[0034] In this embodiment, when using the vibration monitoring device, four insertion rods 5 are inserted downward into the mine soil at the location where the vibration to be monitored in the mining area. During the insertion process, the tip of the bottom of the conical head 6 can break through the mine soil, making it easier for the insertion rods 5 to be inserted downward into the mine soil. Once the four insertion rods 5 are inserted into the mine soil, the monitoring device can be fixed.

[0035] During various blasting and excavation operations, the mining area will experience vibrations of varying degrees. After being fixed in the mining area, the vibration monitoring device can monitor vibrations in real time. Furthermore, under vibration conditions, the stability of the vibration monitoring device can be ensured by fixing the four insertion rods 5, preventing the device from shifting.

[0036] Example 2

[0037] Combination Figure 1-8 As shown, the difference between this embodiment and embodiment 1 is that the insertion rod 5 is a hollow cylindrical shape, and two symmetrical holes are opened on the outer surface of the insertion rod 5. Two fixed protrusions 7 are telescopically arranged in the two holes.

[0038] Each fixed protrusion 7 is slidably installed in the hole on the insertion rod 5. A mounting piece 9 is fixedly attached to the outer surface of each fixed protrusion 7. A spring 8 is sleeved on the outer surface of each fixed protrusion 7. The first end of the spring 8 is connected to the mounting piece 9, and the second end of the spring 8 is connected to the inner surface of the insertion rod 5.

[0039] An installation bearing seat 11 is installed inside the insertion rod 5. A shaped column 10 is rotatably installed inside the installation bearing seat 11. The horizontal cross-section of the shaped column 10 is circular, and two symmetrical arc-shaped concave parts are provided on both sides of the circle. The end of the fixed protrusion 7 near the shaped column 10 is a spherical surface.

[0040] Each irregular column 10 is provided with a torsion assembly at its top. The torsion assembly includes a temporary fixing plate 12 and a handwheel 13. The temporary fixing plate 12 is fixed to the top of the irregular column 10, and the handwheel 13 is fixed to the top of the temporary fixing plate 12.

[0041] After inserting the insertion rod 5 and the conical head 6 into the soil, in order to further ensure the stability of the vibration monitoring device, the handwheel 13 is turned, which will drive the temporary fixing plate 12 and the irregular column 10 to rotate.

[0042] In the initial state, the spherical ends of the two fixed protrusions 7 abut against the arc-shaped concave part of the irregular column 10. At this time, the fixed protrusions 7 do not protrude from the hole of the insertion rod 5. When the handwheel 13 drives the irregular column 10 to rotate, the fixed protrusions 7 leave the arc-shaped concave part of the irregular column 10 and then slide to the outside of the arc-shaped concave part of the irregular column 10. At this time, the radius of the fixed protrusions 7 contacting the irregular column 10 becomes larger, thus pushing the fixed protrusions 7 outward. The fixed protrusions 7 compress the spring 8 through the mounting plate 9, and the fixed protrusions 7 move laterally and insert into the soil, further enhancing the stability and realizing dual fixation in both vertical and horizontal directions, which greatly improves the stability of the vibration monitoring device.

[0043] Example 3

[0044] Combination Figure 1-10 As shown, the difference between this embodiment and embodiment 2 is that the fixing component also includes a temporary positioning component. The temporary positioning component includes a positioning plate 14 and an elastic telescopic rod 15. There are two elastic telescopic rods 15, which are arranged opposite to each other. The telescopic end of each elastic telescopic rod 15 is connected to a positioning plate 14. The two positioning plates 14 are arranged opposite to each other, and the temporary fixing piece 12 is located between the two positioning plates 14.

[0045] Both positioning plates 14 are provided with embedding grooves that match the two ends of the temporary fixing piece 12.

[0046] To ensure the stability of the irregular column 10 before and after rotation, in the initial state, the two ends of the temporary fixing piece 12 are stuck in the embedding groove of the two temporary fixing pieces 12. At this time, the irregular column 10 will not vibrate under the interference of external force vibration.

[0047] After the insertion rod 5 is inserted into the soil for fixation, the two positioning plates 14 are opened to the sides, the elastic telescopic rod 15 is compressed, and then the temporary fixing plate 12 is rotated. After the temporary fixing plate 12 rotates 90 degrees, the fixing protrusion 7 protrudes outward, completing the fixation. At this time, the temporary fixing plate 12 is parallel to the positioning plate 14. Then the two positioning plates 14 spring back and fit against the two sides of the temporary fixing plate 12, forming a limit fixation on both sides. Thus, the irregular column 10 can maintain this state without rotation and will not rotate under external vibration.

[0048] The main body 1 has a handle 2 on the side of the outer shell for easy handling and transfer, making it portable. The top of the main body 1 has a detachable top cover 3 for easy daily maintenance and repair.
