Detailed Description
As shown in fig. 1 and 2, the invention comprises an upper crossbeam 1 which is horizontally arranged, wherein two ends of the upper crossbeam are respectively and rotatably connected with the upper ends of two splayed diagonal braces 2 through pin shafts 3, the lower ends of the diagonal braces are provided with bases, each base comprises a horizontally arranged bottom plate 4, vertical plates 5 which are vertical to the bottom plates are welded on the bottom plates, and the vertical plates 5 are connected with the lower ends of the diagonal braces 2 through pin shafts; two lower cross beams 6 which are parallel to the upper cross beam and have a certain distance with the upper cross beam are arranged below the upper cross beam 1, a plurality of pin holes 7 are respectively arranged on the side walls of the upper cross beam and the lower cross beam at equal intervals along the longitudinal direction, and a strip-shaped sliding hole 8 is arranged on the upper edge of the diagonal brace along the longitudinal direction; a pin shaft 3 for connecting the upper cross beam and the diagonal brace penetrates through a pin hole at the upper end of the diagonal brace and a pin hole on the upper cross beam, pin shafts are respectively inserted between a pin hole at one end of each of the two lower cross beams 6 and a strip-shaped sliding hole 8 on the two diagonal braces, a vertical connecting rod 9 is arranged between the two lower cross beams 6 and the upper cross beam 1, and two ends of the vertical connecting rod 9 are respectively connected with the upper cross beam and the lower cross beam through pin holes on the upper cross beam and the lower cross beam by the pin shafts; the middle of the bottom surface of the upper cross beam 1 is provided with a vertical pulley 10, the other ends of the two lower cross beams are respectively provided with a transverse pulley 11, and the transverse pulleys 11 on the two lower cross beams are opposite and have a certain distance.
Above-mentioned structure makes the support height adjust according to the height of the H shaped steel roof beam of processing, and the interval of the horizontal pulley on two bottom end rails can adjust according to the web thickness of the H shaped steel roof beam of processing.
When the height of the bracket needs to be adjusted, a connecting pin shaft between the diagonal brace rod and the lower cross beam is taken down, the height of the upper cross beam can be raised or lowered by adjusting the inclination of the diagonal brace rod, and after the height is adjusted to a proper height, the pin shaft is inserted into a pin hole which is penetrated by the strip-shaped sliding holes on the lower cross beam and the diagonal brace rod; when the distance between the transverse pulleys on the two lower cross beams needs to be adjusted, the connecting pin shafts of the lower cross beams, the vertical connecting rods and the inclined support rods are firstly taken down, the lower cross beams are transversely moved for a proper distance, and then the lower cross beams, the vertical connecting rods and the inclined support rods are connected through the pin shafts.
