Detailed Description
A move roof beam device for becoming width of cloth case roof beam take one's place, include:
the transverse moving track is arranged above the pier top cover beam;
the mounting seat is fixedly connected with the transverse rail and is provided with a plurality of mounting positions in the length direction of the transverse rail;
the bearing vehicle is used for bearing the box girder to be displaced and is connected with the transverse moving track in a sliding manner;
and the jack is arranged above the transverse rail, one end of the jack is connected with the mounting seat, and the other end of the jack is connected with the bearing vehicle.
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific construction processes are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figure 1, the transverse moving track 1 is composed of two parallel 6-meter-long P24 steel rails, holes are drilled at two ends of the rails and connected and fixed into a whole by high-strength bolts, and round holes with the diameter of 2cm are drilled in the middle of the rail web every 50cm to be used as mounting holes 21, so that the jack 2 can be conveniently fixed. The mounting seat 3 is formed by welding steel plates, comprises a door-shaped cross seat matched with the transverse moving track 1, and is provided with a first insertion hole 31 (used for being connected with the mounting hole 21), a pair of mounting plates are arranged at the top of the door-shaped cross seat, and a second insertion hole 32 (used for being connected with the jack 2) is arranged on the mounting plates. The bearing vehicle 4 adopts 18-shaped channel steel with the length of 120cm as a vehicle body, the opening of the channel steel is downwards matched with the transverse track 1, and a polytetrafluoroethylene plate is arranged on the top surface of the inner side of the channel steel in order to reduce friction; secondly, one end of the channel steel car body is welded with a pair of steel plates as a connecting seat, and the connecting seat is provided with a third inserting hole 41 (used for connecting the jack 2). The jack 2 is located between the mounting seat 3 and the bearing vehicle 4, two ends of the jack are respectively connected with the mounting seat 3 and the bearing vehicle 4 through high-strength bolts, a hydraulic oil cylinder with the stroke of 1m and 100 tons is usually adopted, and the used working fluid is connected with a front leg hydraulic pump station of the bridge girder erection machine through a hydraulic oil pipe.
When in use, the method comprises the following steps (see figure 2): firstly, an electric hoist of a crane trolley in front of a bridge girder erection machine is used for hoisting the transverse moving track 1 to a square timber with a front cover beam put in place. Lubricating grease is smeared on the rail top of the transverse moving rail 1, the bearing vehicle 4 is placed above the transverse moving rail 1 for assembly, the mounting base 3 is fixed on the transverse moving rail 1 through a high-strength bolt, then the jack 2 is mounted between the mounting base 3 and the bearing vehicle 4, the oil inlet pipe and the oil outlet pipe of the jack 2 are connected with a front support leg hydraulic pump station of the bridge girder erection machine, and power is provided by the pump station. Secondly, the rear end of the box girder M to be displaced falls on the designed position support by using a bridge girder erection machine, the front end falls on the bearing vehicle 4, and the steel wire rope is removed. Thirdly, starting the front support leg pump station, slowly pushing the carrying vehicle 4 to move leftwards at a constant speed by the jack 2, and fixing the carrying vehicle 4 after moving for 50 cm; the high-strength bolt between the mounting base 3 and the traverse rail 1 is removed (the 1 st hole is penetrated), the jack 2 is retracted by 50cm, and then the mounting base 3 and the traverse rail 1 are reconnected (the 2 nd hole is penetrated). Fourthly, repeating the third step for multiple times, and pushing the box girder M to be displaced to the designed position in a mode that the jack 2 pushes the box girder M to be displaced to transversely move leftwards and the position of the mounting base 3 is continuously changed. Finally, utilize two 100 tons of low-height jacks will wait to shift the box girder M jacking 2cm, move with the bridge girder erection machine overhead crane calabash the utility model discloses, then place the rubber support in place, return and contract back low-height jack and make and wait to shift box girder M and slowly fall to the rubber support, finish this beam shifting operation.
