[0026] To achieve the above purpose, Figure 1-9As shown, the present invention provides a movable quick-conversion single-leg device for a cantilevered cast-in-place bridge-building machine, which is mainly used for cantilever casting construction of concrete continuous beams of highway and railway bridges, and comprises: a front leg movable running hook 1, a mounting frame 2 and a lifting cylinder 3; the mounting frame 1 is fixedly mounted on the top output end of the lifting cylinder 3, and both sides of the mounting frame 2 are mounted with front leg movable running hooks 1; the front leg movable running hook 1 comprises an arm plate 11, a rotating assembly 12, a walking wheel 13 and a limiting wheel 14; the arm plate 11 is mounted on the mounting frame 2 through the rotating assembly 12, and the walking wheel 13 and the limiting wheel 14 are both rotatably mounted on the arm plate 11, and the walking wheel 13 is located below the limiting wheel 14, the walking wheel 13 is perpendicular to the upper edge of the lower flange plate of the main beam 4, and the limiting wheel 14 is perpendicular to the web of the main beam 4. The front outrigger movable walking hook 1 is used to realize the longitudinal movement and reorganization of the front outrigger on the main beam 4, so that the single-limb front outrigger bridge-building machine is suitable for cantilever casting construction of continuous beams with various segment lengths. The applicable segment lengths include 2.5m, 2.75m, 3m, 3.25m, 3.5m, and 4m, and the module is 25cm.

[0027] When the single leg device is in a non-slip state, the arm plate 11 is connected to the main beam 4 by bolt 15, and the mounting frame 2 is connected to the main beam 4 by bolt 2 16. Before using the front leg movable running hook 1, first remove the bolt 1 connecting the main beam and the front leg, and rotate the front leg movable running hook 270° until the running wheel is perpendicular to the upper edge of the lower flange plate of the main beam, and the limit wheel is perpendicular to the web of the main beam. At this time, there is a gap of 5mm between the lower edge of the running wheel and the upper edge of the lower flange plate of the main beam. Remove the bolt 2 connecting the main beam and the front leg, and let the front leg fall. At this time, the gap between the lower edge of the running wheel and the upper edge of the lower flange plate of the main beam is 0.

[0028] To further optimize the technical solution, ear plates 21 are provided on both sides of the mounting frame 2 , and the rotating assembly 12 is mounted on the ear plates 21 .

[0029] Furthermore, the rotating assembly 12 includes a square pin 121, a stop wedge 122 and a stop sleeve 123; both ends of the square pin 121 are connected with round shafts, the round shaft passes through the arm plate 11 and the ear plate 21, and is rotatably connected to the ear plate 21 and the arm plate 11, the stop wedge 122 is installed on the inner side of the arm plate 11, and is rotatably sleeved on the round shaft, and the stop sleeve 123 is slidably connected to the square pin 121, and is adapted to the stop wedge 122. The front leg movable running hook 1 can rotate 270°, and the module of the stopped state is 45°. The rotation of the front leg movable running hook 1 is achieved by the stop wedge 122 and the stop sleeve 123. When rotation is required, the stop sleeve 123 installed on the square pin shaft 121 is first moved to a position where it does not contact the stop wedge 122. At this time, the front leg movable running hook 1 can rotate along the square pin shaft 121. After rotating to the appropriate position, the stop sleeve 123 is then put on the stop wedge 122 to lock the entire front leg movable running hook 1.

[0030] The present invention has only one front outrigger under the main beam, and the front outrigger can slide along the main beam. The sliding distance is L, which can be 2.5m, 2.75m, 3m, 3.25m, 3.5m, or 4m according to the on-site construction conditions. The front outrigger is connected to the oil cylinder to realize the overall lifting of the main beam, which can be lifted by 150mm.

[0031] The front outrigger of the present invention can slide along the main beam. When the movable running hook of the front outrigger moves, a group of running wheels are perpendicular to the lower flange plate of the main beam, and a group of limiting wheels are perpendicular to the web plate of the main beam for limiting and guiding, thereby solving the problems of manual movement of the front outrigger of the existing suspended grouting bridge-building machine, low adjustment accuracy and long matching beam length; the front outrigger is changed from being transported separately to being self-lifted and slidable, solving the problem of low accuracy and difficulty in getting into place when the original manual moving method is used, and greatly reducing the safety risk; the rotating component facilitates the adjustment of the angle of the movable running hook of the front outrigger, and conveniently locks and fixes the angle to meet its working requirements.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
