The annular convex cones at both ends are convenient for compacting and stabilizing the leveling area, and also avoid excessive outflow of slurry during leveling, resulting in poor leveling effect on the sides, which can play a certain convergence role; the length of the mixing cage roller is set to meet the coverage range and material rush requirements of the mixing concrete; the length of each section of the first and second slurry-raising rollers is set to meet the requirements of the leveling area; 3) Two mixing cage rollers are used, and the material-driving spiral blades can play the role of mixing and driving the concrete, driving the middle material to both sides, so that the thickness of the covering is uniform during leveling, which is more conducive to leveling. The use of two mixing cage rollers can reduce the weight of the support point, and the single mixing power performance is reduced, which is more conducive to controlling the mixing and driving. The use of a lifting bearing seat is convenient for fine-tuning the height of the mixing cage roller, avoiding inconsistent track installation levels of the walking mechanism, and thus adapting to different application occasions, reducing costs, reducing installation requirements, and improving installation efficiency; 4) By rotating the lifting screw rod 1, the lifting screw rod 1 rotates relative to the bearing seat 1, and the threaded portion at the lower end drives the cutter frame 1 to move up and down along the slide groove, thereby fixing the bearing seat 1; 5) Belt drive is adopted, which has low noise and is convenient for realizing rapid power transmission.

The staggered arrangement does not affect the leveling effect caused by leakage at the segmented part; 7) By rotating the lifting screw rod 2, the lifting screw rod 2 rotates relative to the bearing seat 2, and the threaded portion at the lower end drives the cutter frame 2 to move up and down along the slide groove, thereby fixing the bearing seat 1; 8) By rotating the lifting adjustment screw, the lifting adjustment screw rotates around the three fixed points of the bearing seat, and the nut spirally connected to the lower end of the lifting adjustment screw is fixed to the frame. After the lifting adjustment screw rotates, it drives the nut to move up and down, thereby realizing the relative up and down movement of the frame and the door frame. After the adjustment is in place, it is locked by a bolt to realize the height adjustment of the frame, and obtain a large-scale adjustment of the leveling height. The adjustment is convenient and fast, and the adjustment is easy. After the adjustment, the interference between the frame and the embedded steel bars on both sides of the surface to be leveled is avoided.

DETAILED DESCRIPTION
[0016] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Example 1: Figure 1 to Figure 8 As shown, a high-speed railway box girder leveling machine comprises a frame 1, a traveling mechanism 2, a mixing cage roller 3, a first slurry raising roller 4 and a second slurry raising roller 5. The traveling mechanism 2 is installed at both ends of the frame 1. The traveling mechanism 2 is placed on two tracks 7 arranged on both sides of the box girder 6. The mixing cage roller 3, the first slurry raising roller 4 and the second slurry raising roller 5 are arranged at the bottom of the frame 1 from front to back and are respectively connected to a first transmission device, a second transmission device and a third transmission device to drive them to rotate. The first transmission device, the second transmission device and the third transmission device are installed on the frame 1. The lowest points of the mixing cage roller 3, the first slurry raising roller 4 and the second slurry raising roller 5 are 1-2 cm lower than the height of the concrete to be leveled. The mixing cage roller is used to stir and spread the material, the first slurry raising roller is used for rough leveling, and the third slurry raising roller is used for fine leveling, which can greatly improve the leveling effect, avoid the appearance of traditional concrete edges, do not require manual assistance, and save time and effort.
[0018] In order to achieve better leveling, a symmetrical annular concave cone surface 8 is arranged in the middle of the first slurry lifting roller 4 and the second slurry lifting roller 5. The slope of the annular concave cone surface 8 is 2%. Annular convex cone surfaces 9 are arranged at both ends. The inner end of the annular convex cone surface 9 is small and the outer end is large, and the slope is 3%. The annular concave cone surface structure in the middle of the first slurry lifting roller and the second slurry lifting roller is adopted to facilitate the squeezing of the central concrete to both sides, which is more compact and forms a slope structure with a high middle part and low two sides. The annular convex cone surfaces at both ends are convenient for compacting and stabilizing the leveling area, and also avoid excessive outflow of slurry during leveling, resulting in poor side leveling effect, and can play a certain convergence role.
[0019] In order to meet the requirements of leveling, stirring and rushing materials, the length of the stirring cage roller 3 is 7m, and the length of the first slurry raising roller 4 and the second slurry raising roller 5 is 8.6m; in order to meet the requirements of the leveling area, the middle annular concave cone surface 8 of the first slurry raising roller 4 and the second slurry raising roller 5 is 2m long, the straight section length is 2.7m, and the length of the annular convex cone surface 9 at both ends is 0.5m.
[0020] In order to reduce the problem that the mixing cage roller is difficult to mix and drive materials better due to excessive bending during the mixing and driving process, two mixing cage rollers 3 are used, which are rotatably connected to the lifting bearing seat 10 set at the bottom of the frame 1 along the same horizontal axis, and each mixing cage roller 3 is rotatably connected to a lifting bearing seat 10 at both ends, and the lifting bearing seat 10 is fixedly connected to the frame 1. After the power shaft at one end of each mixing cage roller 3 passes through the lifting bearing seat 10, it is connected to a first transmission device and the first transmission device is installed at the outer end. The two mixing cage rollers 3 are provided with reverse spiral driving spiral pieces 301, which can mix and drive materials to concrete, and drive the middle materials to both sides, so that the covering thickness is uniform during leveling, which is more conducive to leveling. Using two mixing cage rollers can reduce the weight of the support point, and the single mixing power performance is reduced, which is more conducive to controlling the mixing and driving.

By rotating the lifting screw 1, the lifting screw 1 rotates relative to the bearing seat, and the threaded part at the lower end drives the cutting frame 1 to move up and down along the slide groove to fix the bearing seat 1. A locking screw 1007 is provided on the side of the door frame 1001. The locking screw 1 can lock the sliding frame 1 after sliding to improve reliability.

The double-row chain improves transmission reliability. A splash plate 17 is installed outside the chain transmission mechanism 14 to prevent concrete slurry from splashing onto the chain and sprocket, thereby playing a protective role.
[0024] In order to avoid excessive bending due to the heavy weight of a single roller, which affects the leveling effect, both ends of the first pulp lifting roller 4 and the second pulp lifting roller 5 are respectively rotatably connected to two sets of lifting bearing seats 11 set at the bottom of the frame 1. The first pulp lifting roller 4 and the second pulp lifting roller 5 both adopt a coaxial two-section roller structure, and the rotating shafts of the separation points of the rollers at both ends are rotatably connected to the frame 1 through the lifting bearing seat 11, and the lifting bearing seat 11 is fixedly connected to the frame 1.

[0025] Specifically, the lifting bearing seat 11 includes a door frame 1101, a sliding frame 1102, a bearing seat 1103 and a lifting screw 1104.

Two lifting adjustment screws 206 are used, which are arranged front and back along the end of the frame 1 (that is, arranged left and right in the width direction of the door frame). Each screw is rotatably connected to the top beam of the door frame 204 through the bearing seat 3 212 near the top, and the lower part is spirally connected to the frame 1 through the nut 213. The top of the lifting adjustment screw 206 is fixedly connected with a rotating ring 219.
