Detailed Description

As shown in fig. 1-3, the pipe jacking sliding device of the utility model comprises a pipe jacking sliding device, which comprises a fixed frame 1, a roller bracket 2, a left roller 3 and a right roller 3, 3'. The left and right rollers 3, 3' are respectively arranged on the roller bracket 2 in a V shape and in bilateral symmetry, the roller bracket 2 is inserted into the sliding groove 11 of the fixing bracket 1 from the upper port of the fixing bracket 1, and the lower end of the sliding groove 11 is provided with a limiting piece 12 for preventing the roller bracket 2 from moving downwards continuously. The fixing frame 1 is also provided with a jacking mechanism 4 capable of jacking the roller support 2 upwards and a connecting piece 5 capable of being connected with the lower flange of the pipe gallery crossbeam 7, and the pipe gallery crossbeam 7 is made of I-steel. The limiting members 12 are two limiting plates 120 welded to the left and right sides of the lower end of the chute 11. The jacking mechanism 4 is composed of two jacking bolts 40 which are respectively in threaded connection with the two limiting plates 120, the upper ends of the jacking bolts 40 penetrate through the limiting plates 120 and then are jacked on the lower end faces of the roller supports 2, and when the jacking bolts 40 are rotated, the roller supports 2 can be adjusted to move up and down. The connecting piece 5 comprises two bottom plates 50 welded on the front side surface of the fixing frame 1 in a bilateral symmetry manner, two front flange pressing plates 51 and two rear flange pressing plates 52; the two front flange pressing plates 51 are respectively positioned above the two bottom plates 50 and welded on the front side surface of the fixing frame 1, and the clamping grooves formed by the front flange pressing plates 51 and the bottom plates 50 are used for being matched with the front lower flange 71 of the pipe gallery crossbeam 7; as shown in fig. 3, the two rear flange pressing plates 52 are L-shaped plates, are respectively connected to the near rear ends of the two bottom plates 50 through bolts 60 and nuts 61, and form a U-shaped slot with an opening facing the fixing frame 1 with the bottom plates 50, and the U-shaped slot is used for matching with the rear lower flange 72 of the pipe rack cross beam 7.

When the pipeline jacking sliding device is used in a construction site, the bolt 60 and the nut 61 for fixing the two rear flange pressing plates 52 are firstly screwed off, and the two rear flange pressing plates 52 are taken off; as shown in fig. 4, the two bottom plates 50 of the pipe jacking skid are then extended into the bottom of the lower flange of the pipe rack beam 7 so that the two front flange pressing plates 51 press on the front lower flange 71 of the pipe rack beam 7; as shown in fig. 5, the two rear flange pressing plates 52 are respectively fixed on the two bottom plates 50 by bolts 60 and nuts 61 and locked, so as to ensure that the front sides of the rear flange pressing plates 52 are tightly pressed on the rear lower flanges 72 of the pipe rack cross beams 7, and after the installation is completed, the highest point of the pipeline jacking sliding device is slightly lower than the upper flange surface of the pipe rack cross beams 7, so that the pipeline jacking sliding device is prevented from influencing the left and right rolling of the pipeline under the non-working state.
