Description

Technical Field

[0001] This utility model relates to the field of column drilling technology, specifically a column drilling machine. Background Technology

[0002] During road construction, guardrails need to be installed on both sides of the road. In the event of a traffic accident, the guardrails can block and buffer vehicles, reducing the damage caused. Highway guardrails generally consist of posts and barriers. During the installation of highway posts, it is sometimes necessary to drill holes in them. Currently, the drilling is done in a workshop, and then the parts are transported to the construction site for installation.

[0003] For example, patent application number 202221161248.2, entitled "A Utility Model Patent for a Drilling Device for Highway Guardrail Posts," includes a base and a frame mounted on top of the base. A lifting platform is mounted on the frame, and a hydraulic cylinder is mounted on top of the frame. The output end of the hydraulic cylinder is connected to the top of the lifting platform via a hydraulic rod. A linear module is mounted at the bottom of the lifting platform, and an inner mounting seat is threaded onto the bottom of the linear module. A drilling motor is located inside the inner mounting seat, and the output end of the drilling motor is connected to a drill bit via a coupling. A protective mechanism is mounted on the inner mounting seat, and an anti-deviation mechanism is mounted on the top of the base. However, in actual construction, the drilling position of the posts needs to be adjusted according to the actual situation. The above solution is only convenient for drilling in the workshop and inconvenient for use on the construction site, and it cannot be used to drill posts that have already been erected.

The right end and the lower end of the fixed frame are respectively provided with support mechanisms that mate with the two sides of the column.

[0007] Furthermore, a through hole is provided on the vertical surface of the fixing frame at the position corresponding to the drill bit of the drilling rig.

[0008] Furthermore, a guide rod is provided on the left side of the fixing frame, and guide sleeves that cooperate with the guide rod are provided on both sides of the drilling rig.

[0009] Furthermore, the guide rod is provided with a handle.

[0010] Furthermore, the drilling rig is equipped with a rotating shaft, a gear is mounted on the rotating shaft, a crossbar is mounted on the left side of the fixing frame, and a rack that meshes with the gear is mounted at the lower end of the crossbar.

[0011] Furthermore, a handle is provided at the end of the shaft.

[0012] Furthermore, the support mechanism includes a positioning groove, a support block disposed in the positioning groove and movable within the positioning groove, and support heads on both sides of the support block that contact the column. The fixing frame is provided with screws that rotate on the fixing frame and drive the support heads to move.

[0013] Furthermore, a clamping screw is provided at the front end of the horizontal part of the fixing frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model includes a fixed frame and a drilling rig located on the left side of the fixed frame and movable left and right. The fixed frame has a groove on its horizontal surface that mates with a column. Support mechanisms that mate with both sides of the column are located at the right and lower ends of the fixed frame. When drilling into an upright column, the groove is first engaged with the column, and the drilling rig is supported on both sides of the column by the support mechanisms. The staggered support mechanisms ensure that the drilling rig can be held in place by its own weight. The drilling rig then moves towards the column to complete the drilling. This method allows drilling into upright columns, has a simple structure, is lightweight, and is convenient for use on construction sites. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] like Figure 1 As shown, a column drilling machine includes a fixed frame 1 and a drilling rig 2 located on the left side of the fixed frame 1 and movable left and right. The fixed frame 1 is a right-angled plate viewed from the side. A groove 3, which mates with a column, is provided on the horizontal surface of the fixed frame 1. Support mechanisms, which mate with both sides of the column, are provided at the right and lower ends of the fixed frame 1. One support mechanism is located at the lower end of the vertical plate of the fixed frame 1, and the other support mechanism is located at the right end of the horizontal plate of the fixed frame 1. The heights of the two support mechanisms are staggered. When drilling into an erected column, the groove 3 is first secured to the column, and the drilling rig is supported on both sides of the column by the support mechanisms on both sides. The staggered support mechanisms ensure that the drilling rig can be secured to the column under its own weight. Then, the drilling rig 2 moves towards the column to complete the drilling. This machine can drill into erected columns, has a simple structure, is lightweight, and is convenient for use on construction sites.

The rotating shaft 7 is equipped with a gear 8. The left side of the mounting frame 1 is equipped with a crossbar 9, and the lower end of the crossbar 9 is equipped with a rack that meshes with the gear 8. When the rotating shaft rotates, the drilling rig 2 moves left and right under the action of the gear and rack.

[0026] like Figure 1 As shown, the end of the rotating shaft 7 is provided with a handle 10.

[0027] like Figure 2As shown, the support mechanism includes a positioning groove 11 and a support block 12 disposed in and movable within the positioning groove 11. Support heads 13 that contact the column are provided on both sides of the support block 12. A screw is provided on the fixing frame 1 that rotates on the fixing frame 1 and drives the support head 13 to move. The screw is rotatably connected to the vertical and horizontal parts of the fixing frame, respectively. A threaded hole is provided in the support head 13, and the threaded part of the screw extends into the threaded hole. Rotating the screw drives the support head to move, thereby ensuring that the support head can be supported on the column and that the fixing frame remains horizontal. The positioning groove 11 serves to limit the position of the support block 12.

[0028] like Figure 1 As shown, the front end of the horizontal part of the fixing frame 1 is provided with a clamping screw 14. When drilling a rectangular tube, the left and right positions of the drill hole can be adjusted by the clamping screw 14.
