Description

Technical Field

[0001] The utility model relates to the technical field of fences, in particular to a mine safety fence. Background Art

[0002] A mine mainly includes one or more mining workshops (or pits, mines, open pits, etc.) and some auxiliary workshops. Most mines also include ore dressing plants. Mining is a technology and science for mining mineral resources from the earth's crust and the surface. The main raw materials for mining and processing are naturally occurring ore bodies. The mine site cannot be freely selected. Mining work is generally carried out in open-pit or underground mines, with heavy labor, poor working conditions, and poor safety. In particular, in mines, due to the complex underground structure and poor light, safety fences need to be placed in some dangerous areas such as deep pits and rockfall areas to prevent workers who are not familiar with the environment from mistakenly entering and causing danger.

[0003] At present, the terrain outside the existing mines is uneven, and the existing safety fences often need to be placed on flat ground during the installation process. If they are set on inclined ground, their overall stability will deteriorate and they cannot be adapted to the terrain outside the mines. For this reason, we propose a mine safety fence. Utility Model Content

[0011] The utility model provides a mine safety fence, which has the following beneficial effects:

[0012] 1. The mine safety fence is coordinated with arc grooves, rotating shafts, horizontal bars, gears, side grooves, sliders, latch teeth, pull rods, springs, pull plates, shaft rods and vertical bars. When setting the fence on the uneven terrain outside the mine, the side pull plate can be used to drive the slider and the latch teeth to move into the side grooves through the pull rod according to the inclination angle of the terrain during the fence setting. At the same time, the latch teeth can contact the limit of the gear to make the two horizontal bars rotate with the rotating shaft as the axis, so that the horizontal bar can be adjusted to the same inclination angle as the setting terrain. After loosening the pull plate, the spring rebounds to reset the slider and fix the horizontal bar by locking the latch teeth into the gear. The adjustment is convenient and quick, suitable for setting and use on the uneven terrain outside the mine, and the setting is convenient and quick, and it is highly compatible with slopes of different angles.

A hole cooperating with the pull rod 10 is provided inside the left column 1 and the right column 2 and on one side of the side groove 7. A limiting groove 13 is provided inside the left column 1 and the right column 2 and on the top and bottom of the side groove 7. A limiting plate 14 is fixedly installed on the top and bottom of the slider 8. The limiting plate 14 is slidably connected with the limiting groove 13. A mounting groove 15 is provided inside the horizontal bar 5. A plurality of shaft rods 16 are fixedly installed inside the mounting groove 15. Vertical bars 17 are rotatably installed on the outer sides of the plurality of shaft rods 16. The function of the mounting groove 15, the shaft rod 16 and the vertical bars 17 is that when the horizontal bar 5 is tilted to adjust the angle, the vertical bars 17 are tilted together with the horizontal bar 5. A drainage hole is provided inside a horizontal bar 5 and below the mounting groove 15, and the drainage hole is located inside the lower horizontal bar 5.

[0022] Two mounting shafts 18 are fixedly installed on one side of the left column 1, and a connecting plate 19 is rotatably installed on the outer side of the mounting shaft 18.

[0023] In summary, when the mine safety fence is in use, when the terrain of the fence area outside the mine is uneven and there is a slope, the side pull plate 12 can be used to drive the slider 8 and the latch tooth 9 to move sideways into the side groove 7 through the pull rod 10, and at the same time, the latch tooth 9 can be made to contact the limit of the gear 6 to make the two cross bars 5 rotate around the rotating shaft 4 as the axis, so that the cross bar 5 can be adjusted to the same inclination angle as the setting terrain. After loosening the pull plate 12, the spring 11 rebounds to reset the slider 8 and fix the cross bar 5 by locking the latch tooth 9 into the gear 6. The adjustment is convenient and fast, and it is suitable for setting up and using on the uneven terrain outside the mine. It is also convenient and fast to set up, and it is highly compatible with slopes of different angles. When the fence on the slope is set up and needs to be connected with another set of fences, it only needs to be rotated to make the through hole 20 and the threaded hole 21 at the same point, and then the fixing bolt 22 is passed through the through hole 20 and then screwed into the threaded hole 21 to complete the installation.
