[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0028] Example 1

[0029] Please refer to Figure 1-4 , a hole opening auxiliary device, comprising:

[0030] The drill tool positioning plate 1 has a diameter of 66 mm and a thickness of 20 mm. It is made of durable metal to ensure its stability and durability during use. A groove 3 is provided in the center of the top of the drill tool positioning plate 1. The size and shape of the groove 3 match the universal positioning bubble 2, so that the universal positioning bubble 2 can be firmly embedded and installed. The universal positioning bubble 2 is used to provide a horizontal or vertical reference during the drilling process to ensure drilling accuracy.

[0031] A positioning rod 4 is fixedly provided in the center of the bottom of the drill tool positioning disk 1. The dimensions of the positioning rod 4 are 80 mm in length and 16 mm in diameter. A conical head 5 is fixedly connected to the bottom thereof. The design of the conical head 5 is convenient for insertion into a small hole opened in advance with a hammer drill, thereby achieving precise positioning and stable support of the entire auxiliary device. During specific operation, a 16 mm hole is pre-drilled in the designed hole position with a hammer drill, the positioning rod 4 is placed in the hole, and the universal positioning level bubble 2 is adjusted to verify the angle. After meeting the requirements, the drilling rig drill set is placed on top of the drill tool positioning disk 1, and drilling is started according to the approved angle to ensure that the hole opening angle meets the design requirements.

[0032] This application can be used for deep hole curtain grouting and opening, and can also be used in other fields applicable to this application.

[0033] Example 2

[0034] Improvements based on Example 1:

[0035] A deep hole curtain grouting hole opening auxiliary device, which is used in the field of hole opening auxiliary devices;

[0036] Please refer to Figure 2 and Figure 4 , an adjustment component is provided at the bottom of the drill tool positioning disk 1, and is used to cooperate with the universal positioning level bubble 2 to adjust the opening angle. The adjustment component is mainly composed of a plurality of screws 6 and hollow support blocks 7. These screws 6 are fixedly arranged at the bottom of the drill tool positioning disk 1 in an annular array, and the number can be set according to actual needs to ensure the flexibility and stability of the adjustment. A hollow support block 7 is threadedly connected to each screw 6. The hollow support block 7 is made of a high-friction rubber material to increase the friction with the ground or other supporting surfaces to prevent sliding or displacement during the drilling process. By rotating the hollow support block 7, the position of the hollow support block 7 in the vertical direction can be easily adjusted, thereby realizing fine-tuning of the inclination angle of the entire auxiliary device, and cooperating with the use of the universal positioning level bubble 2, the angle of the hole can be precisely controlled.

[0037] The working principle and usage process of this technical solution are as follows:

[0038] During drilling, the construction worker uses a hammer drill to drill a hole (16mm in diameter and 100mm in depth) at the designed hole position and angle, places the positioning rod 4 in the hole, and then uses the adjustment component to make precise adjustments. The multiple hollow support blocks 7 at the bottom of the drill positioning plate 1 are rotated to move the hollow support blocks 7 in the vertical direction, thereby changing the inclination angle of the drill positioning plate 1. At the same time, the construction worker continuously observes the universal positioning level bubble 2 and adjusts the universal level bubble to achieve the designed angle.

[0039] Afterwards, the construction personnel put the drilling rig drill bit on the drill bit positioning plate 1, so that the hole-drilling auxiliary device is inside the drill bit when drilling, avoiding deviation of the drilling angle, reducing the gap between the drill teeth and the drill bit locator, drilling slowly, and preventing the drill from getting stuck. In order to avoid operating errors by the construction personnel during the process, an electronic level or angle ruler is used to re-check the angle to ensure that the hole-drilling angle meets the requirements. The hole-drilling auxiliary device can be taken out after the hole is drilled.

[0040] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The embodiments of the present utility model and the features of the embodiments can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present utility model shall be based on the scope of protection of the claims.
