Description

Technical Field

[0001] The utility model relates to the technical field of supports, in particular to a mine lifting protection support. Background Technique

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. Underground coal mines are often equipped with underground protection supports. Publication No.: CN218759964U discloses a mine underground protection support, belonging to the technical field of mine underground protection equipment, including a first fixing plate, and a support column arranged on the top of the first fixing plate. A transmission rod is arranged inside the support column, a turntable is arranged on the top of the transmission rod, a transmission block is arranged on the transmission rod, a support rod is arranged on the transmission block, and a second fixing plate is arranged on the top of the support rod. Through the arrangement of the support column, the transmission rod, the turntable, the transmission block, the support rod and the second fixing plate, rotating the turntable drives the transmission rod to rotate, so that the transmission rod drives the support rod to move through the transmission block, thereby enabling the support rod to push the second fixing plate, playing an adjusting function on the second fixing plate, and further enabling it to well adapt to mine passages of different heights for adjustment. However, in the above technology during use, the second fixing plate and the support rod are fixedly connected by bolts, which makes it necessary to screw down the bolts one by one to replace the second fixing plate when it is necessary to replace the second fixing plate according to the use requirements. This makes the work of replacing the second fixing plate inefficient, and tools are required, which is also not conducive to improving the convenience of replacing the second fixing plate.
