[0025] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0026] A re-rail device for a transverse trolley of a bridge girder hoisting crane of a bridge erecting machine, comprising a re-rail plate 1. The re-rail plate 1 includes a slope plate 101. The slope plate 101 is arranged as a triangle facilitating the alignment of the wheel 8. The slope plate 101 is arranged on one side of the rail 6. The top surface of the slope plate 101 is arranged as a slope surface. The re-rail plate 1 further includes a connecting plate 102. The connecting plate 102 is integrally formed with the slope plate 101. One side of the top surface of the connecting plate 102 is arranged as a slope surface. The bottom of the connecting plate 102 abuts against the top surface of the rail 6. The re-rail plate 1 further includes a second baffle 103 and a third baffle 104. The second baffle 103 is fixedly installed on the hypotenuse of the slope plate 101. The third baffle 104 is fixedly installed on one side of the connecting plate 102. It further includes a fixing component. The fixing component includes a first baffle 2. The first baffle 2 is arranged on the other side of the rail 6. The first baffle 2 is fixed to the re-rail plate 1 through a fixing screw 3. By setting the first baffle 2 and the fixing screw 3 to cooperate, the re-rail plate 1 can be fixed to the rail 6. And by setting the second baffle 103 and the third baffle 104 to cooperate, it is convenient to limit the moving direction of the wheel 8, facilitating the wheel 8 to move to the upper part of the rail 6 through the slope plate 101 and the connecting plate 102, greatly reducing the difficulty of re-railing.

[0027] It further includes an adjusting component, which includes a first backing plate 4 and a second backing plate 5. The first backing plate 4 is arranged between the ramp plate 101 and the track 6, and the second backing plate 5 is arranged between the first baffle 2 and the track 6. By setting the first backing plate 4 and the second backing plate 5 to be used in cooperation, it is convenient to closely fit the re-rail plate 1 and the first baffle 2 to the side of the track 6. And the operator can replace the first backing plate 4 and the second backing plate 5 with different thicknesses, so as to fix the re-rail plate 1 and the first baffle 2 on both sides of the track 6 with different widths, improving the applicable range of the device.

[0028] It further includes several groups of tightening screws 7. The tightening screws 7 are arranged below the re-rail plate 1 and the first baffle 2, and are arranged on both sides of the track 6. The tightening screws 7 respectively penetrate through the first backing plate 4 and the second backing plate 5, and are respectively threadedly connected to the re-rail plate 1 and the first baffle 2. The tightening screw 7 includes a screw body 701 and a tightening plate 702. The screw body 701 is threadedly connected to the re-rail plate 1 and the first baffle 2, the screw body 701 is slidably matched with the first backing plate 4 and the second backing plate 5, the screw body 701 is rotatably connected to the tightening plate 702, and the tightening plate 702 abuts against both sides of the track 6. By setting the tightening screws 7, the stability of the re-rail plate 1 can be improved by pressing the tightening plate 702 against both sides of the track 6, thereby increasing the success rate of re-railing the side-shifting trolley.

[0029] During specific use, move the device to the designated position, move the re-rail plate 1 to the track 6 in front of the wheel 8, fit the ramp plate 101 to one side of the track 6 where the wheel 8 is located, and at the same time place the connecting plate 102 above the track 6, fit the first baffle 2 to the other side of the track 6. After aligning the hole positions, use an external tool to tighten the fixing screw 3 to connect and fix the first baffle 2 and the re-rail plate 1. Then use an external tool to turn the tightening screw 7, so that the screw body 701 pushes the tightening plate 702 to abut against the track 6. Perform the same operation to make other tightening plates 702 abut against the track 6, thereby fixing the re-rail plate 1 on the track 6. Perform the same operation to fix another group of re-rail plates 1 to another track 6. Then use an external power device to pull the side-shifting trolley. The wheel 8 of the side-shifting trolley is pulled by the tensile force. The wheel 8 of the side-shifting trolley drives onto the inclined surface of the ramp plate 101. At the same time, the first baffle 2, the second baffle 103 and the third baffle 104 limit the forward direction of the wheel 8, so that the wheel 8 passes through the inclined surface of the ramp plate 101 and drives onto the upper part of the connecting plate 102, so as to reach directly above the track 6. Continue to pull the side-shifting trolley to make the wheel 8 separate from the re-rail plate 1, and the wheel 8 automatically falls onto the track 6 under the action of gravity, completing the re-railing.
