Embodiment Construction
[0028] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0029] The rotary clamping device for supporting beams used in mining is installed on the lifting platform of the tanker, and includes a rotating base 1, a rotating table 2, a push-pull jack 3, a pin shaft 4 and a bearing 5. The rotating base 1 includes a bottom plate 6 , a rib plate 7 , an inner sleeve 8 , a cover plate 9 , a limiting block 10 and a connecting seat 11 . The rotary table 2 mainly includes a chassis 12 , an outer sleeve 13 , a bent plate 14 , round steel 15 and connecting ears 16 . The outer sleeve 13 of the rotary base 2 is set on the inner sleeve 9 of the rotary base 1, and the bearing 5 is arranged in the middle, and the push-pull jack 3 is respectively connected to the connecting seat 11 of the rotary base 1 and the connecting ear 16 of the rotary base 2 through the pin shaft 4 between. The round steel 15 of the turntable 2 is...

The invention belongs to the technical field of underground coal mine support carrying, and particularly relates to a mine support beam rotating and clamping device. The problems that a single-straddle type support beam of a current coal mine air return crossheading roadway advanced support swings and is difficult to rotate in the carrying process are solved. The mine support beam rotating and clamping device is arranged on a lifting platform of a mine support beam carrying vehicle and comprises a rotation base and a rotation table which are arranged in an up-down manner and can relatively rotate by the limited angle. Two bent plates are symmetrically arranged on the rotation table, a clamping groove is formed, the width of the clamping groove is larger than that of a mine support beam, and the tabletop of the part, between the two bent plates, of the rotation table is provided with a plurality of pieces of evenly-arranged round steel. The arranging direction of the round steel is in the symmetric axis direction of the two bent plates. The round steel on the rotation table and the round steel at the bottom of the mine support beam are arranged in a crossed manner. According to themine support beam rotating and clamping device, the carrying time can be shortened, the labor intensity is relieved, the roadway tunneling efficiency is greatly improved, safety of personnel is guaranteed, and the beneficial effects of flexibility, convenience, time and labor saving and the like are achieved.
Description
technical field [0001] The invention belongs to the technical field of underground support and transportation of coal mines, and in particular relates to a rotary clamping device for a support beam used in mines. Background technique [0002] At present, cross metal articulated beams (or one-shaped beams) combined with single-pillar support are commonly used in the advance support of the return air trough of fully-mechanized mining faces. The labor intensity of workers is high, the risk factor is large, and accidents occur frequently, especially for unmanned This is especially true for the advance support along the gob roadway in coal pillar mining. When transporting the supporting beam from the working face to the front end, since the supporting beam is arranged in the roadway, the transported supporting beam needs to be rotated at a certain angle in the roadway. At present, workers are often used to carry it. It is difficult to move and rotate during the transportation pro...
