Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the steel structure bridge supporting device comprises a base 1, wherein a first supporting column 2, a second supporting column and a disc 3 are sequentially fixed on the base 1 from bottom to top, and a plurality of supporting plates 4 which slide in the radial direction are uniformly distributed on the disc 3;

the second support column includes screw rod 5 and integral key shaft 6, 5 threaded connection of screw rod has nut 7, sliding connection has sleeve 8 about integral key shaft 6, sleeve 8 is located the top of nut 7 and contacts with the up end of nut 7, the lower extreme of backup pad 4 articulates there is connecting rod 9, the other end of connecting rod 9 is articulated with the outer fringe face of sleeve 8, rotate nut 7, nut 7 is along screw rod 5 upper and lower rotary motion, nut 7 drives sleeve 8 and slides from top to bottom along integral key shaft 6, the central point that a plurality of backup pads of sleeve 8 control 4 are synchronous to disc 3 puts and keeps away from or draw close together.

In order to ensure that the support plate 4 and the disc 3 are on the same support plane and achieve the best support effect, the upper surface of the support plate 4 and the upper surface of the disc 3 are on the same horizontal plane.

In order to ensure the stability of the support plate 4 sliding on the disc 3 in the radial direction, the cross section of the support plate 4 is cross-shaped, a sliding groove 10 corresponding to the support plate 4 is arranged in the disc 3, and the support plate 4 is embedded in the sliding groove 10.

In order to ensure the up-and-down sliding stability of the sleeve 8 on the spline shaft 6 and avoid the interference between the sleeve 8 and the screw 5, the sleeve 8 is internally provided with a spline groove 11 matched with the spline shaft 6, and the inner diameter of the sleeve 8 is larger than the outer diameter of the screw 5.

In order to facilitate the worker to rotate the screw cap 7, a plurality of handles 12 are uniformly fixed on the outer edge surface of the screw cap 7.

The spline shaft 6 is sleeved with a pressure spring 13, and the pressure spring 13 is positioned between the sleeve 8 and the disc 3.
