The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of three beam suspension devices mainly comprise the component such as single-beam frame 1, twin beams frame 2, propulsion cylinder 3, hydraulic prop 4; Form supporting roof beam structure unit by a single-beam frame 1 and a twin beams frame 2, the roof beam structure unit bottom is provided with hydraulic prop 4, is hinged with hydraulic drive cylinder 3, hydraulic prop 4 longitudinal arrangements one row.
Referring to Fig. 4, Fig. 5, described single-beam frame 1 comprises back timber 11, joist 12; A described vertical horizontal joist 12 that is provided with more than two in a row in back timber 11 belows longitudinally, back timber 11 is provided with cushion block 13 with the junction of joist 12, and back timber 11 and joist 12 are fixedly connected.
Referring to Fig. 6, Fig. 7, described twin beams frame 2 comprises back timber 21, joist 22; Described two back timber 21 belows are vertically in a row to be provided with plural joist 22, and back timber 21 is provided with cushion block 13 with the junction of joist 22, and back timber 21 and joist 22 are fixedly connected.
Referring to Fig. 8, Fig. 9, after described single-beam frame 1 and 2 assemblings of twin beams frame, the back timber 11 of single-beam frame 1 is positioned at the middle part of roof beam structure unit, two twin beams frame back timbers 21 are arranged on each one of the both sides of single-beam frame back timber 11, the below that is arranged on single-beam frame back timber 11 and twin beams frame back timber 21 at single-beam frame joist 12 and twin beams frame joist 22 intervals, the below of single-beam frame joist 12 and twin beams frame joist 22 is provided with hydraulic prop 4; The place ahead of single-beam frame joist 12 and twin beams frame joist 22 leave the spacing in one step of support reach.One step spacing is between 300 millimeters to 3000 millimeters.
