[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1-3 , the utility model provides a technical solution:

[0019] Embodiment 1:

[0020] like Figures 1-3As shown in the figure, a leveling device for slip form construction of concrete guardrails includes an upper leveling plate 1. A support rod 2 for supporting the upper leveling plate 1 is slidably connected to the inner wall of the upper leveling plate 1. A universal wheel 3 for driving the leveling device to move is fixedly connected to the bottom of the support rod 2. A height adjustment component for fixing the upper leveling plate 1 at a specified height is installed on the support rod 2. A side leveling plate 4 for leveling the side of the concrete guardrail is provided at the bottom of the upper leveling plate 1. The number of side leveling plates 4 is set to two, and the two side leveling plates 4 are symmetrically arranged in a mirror image with the upper leveling plate 1 as the center. A movable plate 5 for driving the side leveling plate 4 to move is slidably connected to the outer wall of the upper leveling plate 1. A horizontal pushing member for driving the movable plate 5 to move is installed on the upper leveling plate 1.

[0021] Embodiment Two:

[0022] It is basically the same as the technical solution of Embodiment One, except that, as Figure 2 shown in the figure, the horizontal pushing member includes a threaded block 6 for driving the movable plate 5 to move. A lead screw 7 for moving the threaded block 6 is rotatably connected to the upper leveling plate 1. The lead screw 7 is threadedly connected to the inner wall of the threaded block 6. A double-shaft motor 8 for driving the lead screw 7 to rotate is provided at the top of the upper leveling plate 1. The number of lead screws 7 is set to two, and the two lead screws 7 are respectively installed at both ends of the double-shaft motor 8. The thread groove directions of the two lead screws 7 are opposite.

[0023] Embodiment Three:

[0024] It is basically the same as the technical solution of Embodiment One, except that, as Figure 3 shown in the figure, the height adjustment component includes clamping holes 9 opened on the outer wall of the support rod 2. The number of clamping holes 9 is set to multiple, and the multiple clamping holes 9 are linearly arranged at equal intervals in sequence. A support frame is fixedly connected to the bottom of the upper leveling plate 1. A clamping column 10 for inserting into the clamping holes 9 is slidably connected to the inner wall of the support frame. A clamping groove 11 is opened at the top of the clamping column 10. A clamping block 12 for inserting into the clamping groove 11 is slidably connected to one side of the upper leveling plate 1. A limiting groove 13 is opened on the outer wall of the upper leveling plate 1. A limiting block 14 for sliding in the limiting groove 13 is fixedly connected to one side of the clamping block 12. The limiting block 14 is arranged in a T shape.

[0025] In summary, when the leveling device for slip form construction of concrete guardrails provided in this embodiment faces concrete guardrails of different specifications, the staff first grasp the clamping block 12 and move it upward, so that the clamping block 12 will be taken out of the clamping groove 11. Then the clamping column 10 will lose its limit, and the staff can take out the clamping column 10 from the clamping hole 9. Then the staff can adjust the height of the upper leveling plate 1 according to the height of the concrete guardrail. After the height adjustment is completed, the staff reinsert the clamping column 10 into the clamping hole 9, and then release the clamping block 12. The clamping block 12 will automatically move downward due to gravity and fall into the clamping groove 11, so that the upper leveling plate 1 can be fixed at the specified height. Then the staff turn on the double-shaft motor 8, and the double-shaft motor 8 will drive the lead screw 7 to rotate. The lead screw 7 will drive the movable plate 5 to move through the threaded block 6, and the movable plate 5 will drive the side leveling plate 4 to move. In this way, the staff can adjust the distance between the two side leveling plates 4 to cope with concrete guardrails of different widths.
