Description

Technical Field

[0001] The utility model relates to the technical field of coal mine mining, and more specifically, it relates to a fully-mechanized coal mining support structure for coal mines. Background Art

[0002] Fully-mechanized coal mining (referred to as fully-mechanized mining for short) is a modern coal mining technology. It realizes the continuous, efficient, and safe mining of coal resources by comprehensively applying a variety of mechanized equipment. During coal mining, the interior of the roadway needs to be supported. Currently, the support method for the roadway roof usually uses a support frame and an anchor mesh in cooperation to enhance the support strength of the coal mine roadway. The general construction sequence is to first fix the metal mesh on the roadway roof with a backing plate or a bolt, and then assemble or lift the support frame so that it presses against the metal mesh and tightly fits the roadway roof for support.

[0003] For the anchor mesh support for the roadway roof first, during the support process, coal miners usually need to manually hold the metal mesh against the roadway roof, and then fix the metal mesh with bolts to form the anchor mesh support. This manual action of holding the metal mesh greatly increases the labor intensity of coal miners, and multiple workers are required to cooperate to complete the lifting and installation of the anchor mesh, which also increases the labor cost and reduces the work efficiency. However, the existing support frame is not easy to assemble, and it is not easy to adjust the height of the support frame according to the size and height of the roadway after assembly.

[0034] In summary, when the overall equipment is in use or operation: when assembling the support frame 1, insert one end of the support rod 4 into the support plate 3, and the support plate 3 squeezes the clamping block 12 inward, causing the clamping block 12 to extend into the clamping groove 11 and compress the clamping spring 13. When the clamping block 12 completely passes through the support plate 3, the clamping block 12 extends out under the elastic force of the clamping spring 13. By moving the sliding block 18 in the sliding groove 19, the moving direction and position of the clamping block 12 are restricted. According to the thickness of the support plate 3, rotate the moving knob 17, and the moving knob 17 drives the moving screw 16 to rotate. The moving screw 16 drives the moving block 10 to move in the moving groove 9. Through the cooperation of the clamping block 12 and the fixing ring 8, the position of the support rod 20 is clamped and fixed. When laying the anchor net, through the cooperation of the rotating ring 14 and the rotating groove 15, drive the support plate 6 and the support plate 6 to rotate on the support rod 20, and then support and lay the anchor net at the roof of the roadway. The staff drives the anchor rod into the roof of the roadway through the gap between the support rods 4 to fix the position of the anchor net.

[0035] When adjusting the height of the support frame 2, rotate the reset ring 27 so that the reset ring 27 moves upward, squeezing the reset head 26, causing the connecting plate 23 and the limiting rod 22 to move outward to the circumference of the support sleeve 21, stretching the limiting spring 25, synchronously adjusting the height of the support rod 20 on the support sleeve 21, and adjusting the support heights of the support frame 2 and the support rod 4.
