Description

Technical Field

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

[0002] In the early stages of mining, mining support devices are used to support rock formations, prevent the top or side walls of the mine from collapsing, and ensure the safety of miners. At this stage, the support devices not only prevent rocks from sliding down, but also support the mine walls to prevent collapse.

[0003] The prior art patent document CN220815692U discloses a mining roadway support device, including a top mechanism, a connecting mechanism, a support mechanism, and a base mechanism. The width of the mining roadway support device is adjusted by the extension and retraction of a telescopic rod. Inner and outer protective plates prevent mud and sand from entering the telescopic rod, improving the practicality and adjustability of the mining roadway support device. Simultaneously, the lower part of the connecting protrusion rotates into the movable end of the telescopic column, improving the stability of the mining roadway support device. Furthermore, the connecting groove is connected to the support rod by bolts pressing the outer surface of the support rod, making disassembly of the mining roadway support device simple. The bolts are arranged in a fixed groove, and a sealing cover and sealing plate isolate the bolts from the outside environment, preventing moisture and corrosive liquids from corroding the bolts, thus improving the service life and installation effect of the mining roadway support device. Finally, a trapezoidal base block is set under the base plate to increase the contact area with the ground and prevent collapse.

[0004] In existing technologies, the width of mining roadway support devices is adjusted by extending and retracting telescopic rods. However, since only the support width can be adjusted, the side and lateral aspects of the support cannot be adjusted. This makes it unsuitable for the complex geological conditions in different areas of the mine. The geological structure of a mine is constantly changing. If the support device cannot adjust the support range in all directions, it may not provide sufficient support in some special areas, causing safety hazards. Utility Model Content

The sliding support plate 332 can slide outward under the drive of the cylinder a331, thereby extending the lateral support space.

[0025] Both outer sides of the arc-shaped support plate 31 are fixedly connected to connecting plates 34, which provide installation positions for support blocks 35. Multiple support blocks 35 are fixedly connected to the outer sides of the two connecting plates 34. The rear side of each support block 35 is rotatably connected to the front side of the connecting plate 34. The support blocks 35 serve as support and rotation fulcrum for the rotating support plate 36. The inner side of each support block 35 is rotatably connected to the rotating support plate 36. The rotating support plate 36 can adjust its angle by rotation to adapt to the support requirements of the mine side. A rotating assembly 37 is fixedly connected to the bottom of the arc-shaped support plate 31. The rotating assembly 37 is... The rotation of the rotating support plate 36 is powered.

The bottom of the screws 382 is connected to the ground, further reinforcing the telescopic column 2.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the side support mechanism 4 includes a fixed plate 41. The inner side of the fixed plate 41 is fixedly connected to the outer side of two telescopic columns 2. The fixed plate 41 provides a stable mounting base for the cylinder c42.

The outer sides of the multiple support fences 47 are rotatably connected to the inside of the fixed block 45, ensuring the stability of the support fences 47 when rotating.

[0029] Working principle: The base plate 1 provides a stable foundation for the entire device. Operating multiple telescopic columns 2 allows them to extend and retract according to the mine's height, raising the top telescopic support mechanism 3 to a suitable height. Within the telescopic support mechanism 3, multiple arc-shaped support plates 31, supported by the telescopic columns 2, adhere to the mine's top, and the bottom protective netting 32 unfolds accordingly, forming initial protection. When it is necessary to expand the lateral support range, the cylinder a331 in the telescopic assembly 33 on the outer side of the arc-shaped support plate 31 is activated, and the sliding support plate 332 at the output end extends from the arc-shaped support... The inner side of plate 31 slides out, extending the support width. At the same time, the support block 35 on the connecting plate 34 on both sides of the arc-shaped support plate 31 serves as a fulcrum. Under the action of the rotating component 37, the angle is adjusted. The cylinder b372 on the support plate 371 extends and retracts, driving the rotating support plate 36 to rotate up and down inside the support block 35 to adapt to the support requirements of different heights on the side of the mine. The reinforcement component 38 outside the telescopic column 2 operates synchronously, rotating the multiple screws 382 on the fixing ring 381, so that the bottom of the screws 382 penetrates deep into the ground, enhancing the overall stability.

[0030] In the side support mechanisms 4 on both sides, the cylinder c42 on the fixed plate 41 is activated, and the drive plate 43 at the output end drives the support fence 47 to move. The rotating rod 46 in the fixed block 45 on the base 44 assists in the rotation of the support fence 47, so that multiple support fences 47 are adjusted to a suitable angle, forming an effective protection for the bottom side of the mine, preventing falling rocks from rolling into the working area, protecting the safety of workers, and completing the comprehensive support of the mine.
