Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically a warning device for collapse areas in open-pit coal mines. Background Technology

[0002] After open-pit coal mining, the overlying rock strata will deform, move and break down, forming subsidence areas. These areas may have safety hazards such as ground subsidence and cracks. Therefore, warning devices are needed to warn people to stay away from the open-pit coal mining subsidence areas.

[0003] In the prior art, such as the warning device for coal mine subsidence areas proposed in patent application number "CN202321375059.X", there are two sets of installation components that are set at intervals during use and connected by a warning line. This not only serves as a warning but can also be collected and processed for future use when not in use.

[0004] However, in the aforementioned patent applications, the warning devices are located at a low height, and when they are located at a distance, the line of sight is easily blocked. It is necessary to get close to see the warning devices, and the warning distance is limited, making it impossible to obtain warning information directly from a distance. Utility Model Content

[0031] like Figure 1 , Figure 3 and Figure 4 The fixed frame 8 has a movable groove 801 on one side, and a connecting shaft 13 is fixedly connected to one side of the sliding block 12. One end of the connecting shaft 13 extends to the outside of the fixed frame 8 and is fixedly connected to a positioning collar 14. The connecting shaft 13 passes through the movable groove 801, so that the sliding block 12 can move together with the positioning collar 14.

[0032] like Figure 1 , Figure 3 and Figure 4 Both ends of the winding shaft 202 are rotatably connected to a lateral shaft 15, and a positioning collar 14 is fitted onto the outer surface of the lateral shaft 15 to achieve the installation and positioning of the winding shaft 202.

[0033] The working principle of the warning device for collapse areas in open-pit coal mines provided by this utility model is as follows:

[0034] The vertical support 1 is installed at the edge of the subsidence area of ​​the open-pit coal mine. The two positioning sleeves 14 are pulled away from each other, and the winding shaft 202 is placed on the two positioning sleeves 14. The positioning sleeves 14 are released. Under the action of the tension spring 11, the sliding block 12 drives the positioning sleeves 14 to move closer to each other through the connecting shaft 13. The positioning sleeves 14 are put on the lateral shafts 15 at both ends of the winding shaft 202, completing the installation of the winding shaft 202. Then, the movable shaft 201 is fixed to the connecting block 3 by the fixing bolt 6.

[0035] The rotating winding disc 4 winds the connecting rope 5, and the other end of the connecting rope 5 drives the connecting block 3 to move upward. The connecting block 3 drives the movable shaft 201 to move upward. The movable shaft 201 drives one end of the vertical banner 2 to move upward. The winding shaft 202 releases the vertical banner 2, so that the vertical banner 2 is finally unfolded at a high position on one side of the vertical support 1. The warning signs above the vertical banner 2 are used to warn people of the collapse area in the open-pit coal mine.

[0036] Compared with related technologies, the warning device for collapse areas in open-pit coal mines provided by this utility model has the following beneficial effects:

[0037] This invention, by setting up a vertical support 1, installs the two ends of the movable shaft 201 and the winding shaft 202 at both ends of the vertical banner 2 onto the connecting block 3 and the fixing frame 8 respectively. This allows the rotating winding disc 4 to drive the movable shaft 201 upward through the connecting rope 5, quickly unfolding the vertical banner 2 to a high position on the vertical support 1. This allows pedestrians to see the warning signs on the vertical banner 2 from a greater distance. When used in open-pit coal mining collapse areas, it can provide a warning to pedestrians at a greater distance, further improving the safety of open-pit coal mining collapse areas. At the same time, the installation of the vertical banner 2 does not require manual climbing onto the vertical support 1; the installation of the vertical banner 2 can be completed at a lower position, making the installation of warning signs more convenient and quick.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
