Detailed Description
Referring now to the drawings in the specification, in conjunction with specific embodiments, there is illustrated the following: a net gripper is closed before gangue filling working face hydraulic support face for coal mine, including fixed plate 1, connecting plate 2, elastic rod 7 and couple 4. The fixing plate 1 is a main body part, two parallel connecting plates 2 are arranged on the front surface of the fixing plate 1, a hook 4 is rotatably arranged between the two connecting plates 2 and at the lower part of the connecting plates, and the hook 4 is hinged with the two connecting plates 2 through a connecting rotating shaft 3. A first connecting pipe 5 is arranged at the upper part of the outer side of one connecting plate 2, a second connecting pipe 6 is arranged below the first connecting pipe 5 and on one side of the hook body of the hook 4, an elastic rod 7 is arranged between the first connecting pipe 5 and the second connecting pipe 6, the top end of the elastic rod 7 is inserted into the first connecting pipe 5, the bottom end of the elastic rod 7 is inserted into the second connecting pipe 6, the rod body of the elastic rod 7 abuts against the inner shaft wall of the connecting rotating shaft 3 and is slightly bent outwards along the circumferential direction of the connecting rotating shaft 3 as a supporting shaft, and the whole elastic rod 7 is arc-shaped. One side of the two connecting plates 2, namely one side of the fixing plate 1, is provided with a through hole 1-1, and a fixing bolt is arranged in the through hole 1-1.
Furthermore, an arc-shaped groove body 3-1 is arranged at the abutting position of the connecting rotating shaft 3 and the elastic rod 7, and the rod body of the elastic rod 7 is movably arranged in the arc-shaped groove body 3-1.
Furthermore, two ends of the elastic rod 7 are respectively provided with a connecting column 8, the two connecting columns 8 are respectively arranged in the first connecting pipe 5 and the second connecting pipe 6, a threaded hole 8-1 is formed in a column body of the connecting column 8, through holes corresponding to the threaded hole 8-1 are respectively formed in pipe bodies of the first connecting pipe 5 and the second connecting pipe 6, and the connecting column 8 is inserted into the two connecting pipes and fixed through bolts.
