Description

Technical Field

[0001] The utility model relates to the technical field of drilling construction, and more specifically, to a multi-hole vertical drilling device in a narrow space. Background Art

[0002] Drilling construction is a common basic process in the field of bridge maintenance and reinforcement. Drilling is usually used for reinforcement measures such as planting reinforcement and installing anchor bolts, and to achieve construction contents such as installing temporary structures on existing structures to assist in construction or adding new structures to achieve reinforcement. In addition, drilling can be equipped with sleeves to break concrete at existing structures to achieve other construction contents such as concrete breaking and installation of measuring equipment. Due to the different forms and construction contents of various bridge structures, the environmental conditions for drilling construction are also different. Under the condition of sufficient space for drilling construction, it is not difficult to ensure drilling accuracy and verticality. However, in a small space, there is not enough space left for people and drilling equipment, and even the conditions for normal drilling construction are not met. Therefore, how to ensure the normal progress of drilling construction in a small space, create convenient conditions for multi-hole drilling, and ensure the accuracy of drilling are currently the difficulties in drilling construction in a small space.

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0020] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a multi-hole vertical drilling device in a narrow space, which is used for drilling construction on a vertical structural surface in a narrow space, comprising:

[0022] A support base 2 is vertically arranged, and telescopic rods 4 are respectively arranged at the upper and lower ends of the support base 2; a plurality of mounting holes are opened on the support base 2 along its longitudinal axis, and the hole spacing of the mounting holes is the same as the vertical hole spacing on the vertical structural surface;

[0023] A sliding base 3 is vertically arranged, and a fixing bolt 8 is threadedly connected to the center of the sliding base 3, and the diameter of the fixing bolt 8 matches the diameter of the mounting hole; a mounting rod 5 is fixedly arranged on one side of the sliding base 3, and the mounting rod 5 is horizontally arranged;

[0024] The water drill 7 has one side slidably connected to the mounting rod 5; the center of the drill bit of the water drill 7, the center of the mounting rod 5 and the center of the sliding base 3 are in the same plane.

[0025] In this technical solution, the fixed end of the telescopic rod 4 is connected to the support base 2. First, the support base 2 is made to abut against the inner wall on one side, and then the length of the telescopic rod 4 is adjusted so that its movable end abuts against the inner wall on the other side, thereby fixing the support base 2 on the inner wall on one side of the narrow space. Taking the concrete demolition construction of a water-retaining cofferdam in a certain engineering project as an example, the multi-hole vertical drilling equipment in the narrow space is described. The area to be demolished of the cofferdam 1 is located at the bottom of the cofferdam, with a length of 9.5m, a height of 0.6m, and a demolition depth of 0.3m. The adjacent structure is a three-step graded pier 6, with a length of 9.5m and a first step height of 2.65m. A narrow space with a net distance of 0.6m is formed between the cofferdam 1 and the pier 6; the side of the cofferdam 1 facing the pier 6 is the vertical structural surface, and the area to be demolished is designed with array holes. The hole spacing of the mounting holes on the support base 2 is the spacing between two adjacent holes in the same row of holes. When in use, first adjust the length of the two telescopic rods 4 so that their movable ends abut against the surface of the pier 6 to complete the installation of the support base 2; then install the sliding base 3 to the first mounting hole from top to bottom through the fixing bolts 8, and then connect the water drill 7 to the mounting rod 5; preferably, the fixing bolts 8 can be expansion bolts. Then start the water drill 7 to drill holes, turn it off after completing the first drilling, loosen the fixing bolts 8 on the sliding base 3, and fix it to the next mounting hole, and then continue drilling. After completing the first row of drilling holes, loosen the telescopic rods 4, move the support base 2 to the next row of designed hole positions, and drill the next row of holes. Repeat the above operations until all holes in the area to be drilled are completed.

[0026] In another technical solution, the sliding base 3 is a rectangular steel plate, and leveling bolts 9 are respectively arranged at its four corners. One end of the leveling bolt 9 abuts against the support base, and the verticality of the sliding base 3 is ensured by the leveling bolt 9, thereby ensuring the drilling quality.

[0027] In another technical solution, the support base 3 is a channel steel, and its length covers the vertical length of the drilling construction area on the vertical structural surface; that is, a vertical row of holes can be drilled through the support base 3, further improving the drilling efficiency.

[0028] In another technical solution, a sliding support 11 is fixedly connected to one side of the water drill 7, and the sliding support 11 is sleeved on the mounting rod 5 and slidably connected to the mounting rod 5. The distance of the water drill 7 relative to the cofferdam 1 is adjusted by the sliding support 11 to perform the withdrawal work of the drill and the drill bit.

[0029] Specifically, a rack 10 is provided on the mounting rod 5 along its longitudinal axis, and a gear meshing with the rack 10 is rotatably connected in the sliding support 11. A rocker is provided on one side of the sliding support 11, and one end of the rocker is coaxially and fixedly connected with the gear. The construction personnel drives the gear to rotate by rotating the rocker, thereby driving the water drilling machine 7 to slide along the mounting rod 5. In order to further improve the drilling efficiency, a driving motor can also be installed on the sliding support 11, and the output shaft of the driving motor is coaxially and fixedly connected with the gear, so that the driving motor drives the gear to rotate.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
