[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] like Figures 1-4 As shown, a hole drill fixing frame for reinforced concrete guardrail includes: an mounting plate 1 placed on top of the reinforced concrete guardrail 24, the mounting plate 1 being provided with a connecting device for mounting a water drill 2, and an extension plate 3 being provided at each end of the mounting plate 1, the extension plate 3 being provided with a positioning device for positioning the mounting plate 1 on the reinforced concrete guardrail 24.

[0016] To facilitate the positioning of the mounting plate 1, and thus the positioning of the water drill 2 mounted on the mounting plate 1, the positioning device includes: one end of the extension plate 3 is provided with a bearing plate 4 for pressing against the back of the reinforced concrete guardrail 24, and the other end of the extension plate 3 is provided with a pressure plate 5. The pressure plate 5 is provided with a pressure device for applying pressure to the reinforced concrete guardrail 24 to press the bearing plate 4 against the reinforced concrete guardrail 24.

[0017] To facilitate pressing the pressure plate onto the reinforced concrete guardrail 24, the pressure application device includes: a first nut seat 6 at the bottom of the pressure plate 5, a first positioning screw 7 locked inside the first nut seat 6, and a first base plate 8 for enhancing friction on the first positioning screw 7.

[0018] In order to improve the strength of the pressure plate 4 and the pressure plate 5, thereby improving the stability of the fixed frame, a first reinforcing plate 9 is provided between the pressure plate 4 and another pressure plate 4, and a second reinforcing plate 10 connected to the first reinforcing plate 9 is provided between the pressure plate 4 and another pressure plate 4. The first reinforcing plate 9 is located at the bottom of the pressure plate 4, and the second reinforcing plate 10 is perpendicular to the first reinforcing plate 9. A third reinforcing plate 11 is provided between the pressure plate 5 and another pressure plate 5. A fourth reinforcing plate 12 connected to the third reinforcing plate 11 is also provided between the pressure plate 5 and another pressure plate 5. The third reinforcing plate 11 is located at the bottom of the pressure plate 5, and the fourth reinforcing plate 12 is perpendicular to the third reinforcing plate 11.

[0019] To enhance positioning stability, a second nut seat 13 is provided on the pressure plate 5 above the first nut seat 6. The second nut seat 13 is provided with a second positioning screw 14, and the second positioning screw 14 is provided with a second base plate 15 for enhancing friction.

[0020] To facilitate the installation of the water drill 2, the connecting device includes: at least one mounting screw 16 fixed on the mounting plate 1, perpendicular to the mounting plate 1; The water drill 2 is an existing drilling device, and its base is usually provided with a mounting groove 17.

[0021] To facilitate rotation of the first positioning screw 7 and the second positioning screw 14, the first positioning screw 7 is provided with a first rotation hole 18, a first rotation rod 19 is inserted into the first rotation hole 18, and a first engaging part 20 is provided on the first rotation rod 19. The second positioning screw 14 has a second rotating hole 21, a second rotating rod 22 is inserted into the second rotating hole 21, and a second engaging part 23 is provided on the second rotating rod 22.

[0022] like Figure 4 As shown, the reinforced concrete guardrail 24 is a standard component, and its shape and structure are fixed. Not every guardrail of any shape is a reinforced concrete guardrail 24. The first nut seat 6 and the second nut seat 13 are both located below the protrusion 25 on the reinforced concrete guardrail 24.

[0023] Working principle: When in use, the mounting plate 1 is placed on top of the reinforced concrete guardrail 24. Then, the first positioning screw 7 and the second positioning screw 14 can be rotated by the first rotating rod 19 and the second rotating rod 22, respectively. Since the first positioning screw 7 is threaded to the first nut seat 6 and the second positioning screw 14 is threaded to the second nut seat 13, the first positioning screw 7 and the second positioning screw 14 will move towards the reinforced concrete guardrail 24 along the axial direction of the first nut seat 6 and the second nut seat 13, respectively. This causes the first base plate 8 and the second base plate 15 to abut against the reinforced concrete guardrail 24, thus completing the positioning of the mounting plate 1. At this point, the water drill 2 can be installed on the mounting plate 1, so that the mounting screw 16 passes through the mounting groove 17 on the base of the water drill 2, and then the water drill 2 is locked with nuts and washers, and drilling operations can begin.
