Description

Technical Field

[0001] This utility model relates to the field of drill rod technology, specifically an assembled drill rod for drilling anchor bolt holes on slopes. Background Technology

[0002] Existing methods for drilling anchor bolt holes on slopes are mainly divided into two types based on the drilling depth. One method involves erecting a scaffolding operating platform and using motor-controlled equipment and a continuous drill rod for drilling. However, the subsequent erection and dismantling of scaffolding significantly increases the construction period and cost. Furthermore, if the drill rod is too long, the construction quality is difficult to control. The other method uses a suspended operation, where safety ropes and operating ropes are set up at the top of the slope, and operators drill directly on the slope surface. However, this method has limited applicability, and the drill rods become unsuitable once they reach a certain length. Therefore, existing technology utilizes prefabricated drill rods. During construction, after each section of the drill rod is drilled to its full length, the next section is connected to the end of the drill rod. The shorter rod length ensures that the operators are always in the most convenient working posture.

[0003] For example, patent publication number CN216043580U discloses an assembled active drill rod, which includes a rod body, a connector threaded to one end of the rod body, and a sliding sleeve sleeved on the rod body and connector and connected by gear meshing. The sliding sleeve is fixed to the rod body with screws to prevent axial movement. This assembled active drill rod solves the technical problems in the prior art where the connector thread is prone to failure, resulting in long drill rod replacement time, high processing costs, and significant waste.

[0004] While the aforementioned device solves the problem of easy failure of the joint threads, it still has the following shortcomings: During drilling operations, when one section of the drill rod has been partially drilled into the soil, it is necessary to connect the next section of the drill rod to the tail of the previous section. Although a bolt-type connector is used, the positioning of this connection method is relatively complicated in actual operation, increasing the difficulty and inconvenience of connecting the two sections of the drill rod. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an assembled drill rod for drilling anchor bolt holes on slopes, which makes the drill rod easier to position during assembly and makes the connection more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembled drill rod for drilling anchor bolt holes on slopes, comprising two drill rod bodies and an assembly joint connected between the two drill rod bodies. The inner sides of the ends of the two drill rod bodies are provided with assembly grooves. The two ends of the assembly joint are fixedly connected with end rods threaded to the assembly grooves. The outer end of the assembly groove is provided with a guide chamfer. The outer wall of the end rod near the assembly joint is provided with a matching chamfer corresponding to the guide chamfer. The two ends of the assembly joint are connected with overlapping components.

[0007] Furthermore, the overlapping assembly includes an overlapping plate, a sliding groove is provided at the end of the drill rod body, a receiving plate is slidably connected in the sliding groove, an overlapping groove is provided on the top surface of the receiving plate, and the overlapping plate and the overlapping groove are correspondingly arranged.

[0008] Furthermore, the cross-section of the receiving plate at one end of the chute is T-shaped.

[0009] Furthermore, a protective ring is slidably connected to the outer side of the assembly joint, and the protective ring is threadedly connected to the outer side of the drill pipe body.

[0010] Furthermore, the outer wall of the assembly joint is fixedly connected with two symmetrically arranged limiting rings, and the inner wall of the protective ring is provided with a moving groove corresponding to the limiting rings.

[0011] Furthermore, compression pads are fitted on both sides of the outer wall of the assembly joint, and the outer wall of the compression pads abuts against the end of the drill pipe body.

[0012] Furthermore, the outer wall of the assembly joint has two symmetrically arranged tool clamping slots.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model provides a guide chamfer at the outer end of the assembly groove of the drill pipe body and a matching chamfer at the outer end of the assembly joint, making it easier for the end rod of the assembly joint to connect with the assembly groove and for positioning, thus making the connection more convenient and smooth. The structure is simple, easy to operate, and highly practical.

[0015] 2. By combining the support plate and the mounting plate, this utility model makes it easier to assemble the two drill rod bodies, eliminating the need for workers to constantly lift the drill rod bodies to be assembled. At the same time, the pushing of the mounting plate on the support plate also serves as a positioning effect, allowing the end rod to be directly inserted into the assembly slot.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 5 As shown, an assembled drill rod for drilling anchor holes on slopes includes two drill rod bodies 1 and an assembly joint 2 connected between the two drill rod bodies 1. The inner sides of the ends of the two drill rod bodies 1 are provided with assembly grooves 11. The two ends of the assembly joint 2 are fixedly connected with end rods 4 threaded to the assembly grooves 11. The outer ends of the assembly grooves 11 are provided with guide chamfers 12. The outer wall of the end rods 4 near the assembly joint 2 is provided with matching chamfers 41 corresponding to the guide chamfers 12. The two ends of the assembly joint 2 are connected with overlapping components.

[0024] like Figure 1 As shown, the prefabricated drill rod for drilling slope anchor holes in this utility model is similar in structure to existing prefabricated active drill rods, such as the prefabricated active drill rod disclosed in patent publication number CN216043580U. The main improvement of this utility model is that it makes the drill rod easier to position during assembly, such as... Figures 1 to 5 As shown, when using the prefabricated drill rod for drilling anchor holes in the slope of this utility model, before the worker starts drilling, the assembly joint 2 should be installed on the end of each unassembled drill rod body 1. The end rod 4 of the assembly joint 2 is connected to the assembly groove 11 in the drill rod body 1 to be assembled, so that the end rod 4 and the assembly groove 11 are tightly threaded together. This allows the outer end of the drill rod body 1 located inside the slope to be separated from the motor control equipment. Through the overlapping component, the end rod 4 at the other end of the assembly joint 2 is threadedly connected to the assembly groove 11 at the outer end of the drill rod body 1 located inside the slope. Then, one end of the assembled drill rod body 1 is connected to the output shaft of the rotary motor in the motor control equipment, thereby driving the assembled drill rod body 1 to rotate and drill.

[0025] It is worth noting that the output shaft of the rotary motor in the motor control equipment should have the same structure as the assembly joint 2 to ensure that it can be connected to both the output shaft of the rotary motor and the end rod 4 of the assembly joint 2.

[0026] By setting a guide chamfer 12 at the outer end of the assembly groove 11 of the drill pipe body 1 and a matching chamfer 41 at the outer end of the assembly joint 2, the end rod 4 of the assembly joint 2 can be easily connected to the assembly groove 11, making positioning easier and the connection more convenient and smoother.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the overlapping assembly includes an overlapping plate 5, a sliding groove 13 is provided at the end of the drill rod body 1, a receiving plate 6 is slidably connected in the sliding groove 13, and an overlapping groove 61 is provided on the top surface of the receiving plate 6. The overlapping plate 5 and the overlapping groove 61 are correspondingly arranged.

[0028] Specifically, to make the assembly of the drill rod body 1 more convenient, the receiving plate 6 at the end of the drill rod body 1 located in the slope hole can be slid out, and then the mounting plate 5 at the end of the drill rod body 1 to be assembled can be placed on the groove 61 on the receiving plate 6. Then the drill rod body 1 to be assembled can be pushed directly, driving the assembly joint 2 (at this time, the end rod 4 at one end of the assembly joint 2 is already connected to the drill rod body 1 to be assembled), driving the end rod 4 to be inserted into the assembly groove 11 of the drill rod body 1 located in the slope. At this time, since the mounting plate 5 rests on the receiving plate 6, it can make the assembly of the two drill rod bodies 1 less strenuous, and the worker does not need to keep lifting the drill rod body 1 to be assembled. At the same time, the sliding connection of the mounting plate 5 on the receiving plate 6 also plays a positioning role, so that the end rod 4 can be directly inserted into the assembly groove 11.

[0029] After the end rod 4 is inserted into the assembly slot 11, the drill rod body 1 to be assembled is rotated, which drives the end rod 4 to be threadedly connected to the drill rod body 1 located in the slope hole. During the threaded connection, the lap plate 5 can lose its overlap with the support plate 6, and the support plate 6 does not restrict the rotation of the lap plate 5, which facilitates the smooth rotation of the assembly joint 2.

[0030] It is worth noting that the outer end of the receiving plate 6 can be provided with a structure that facilitates its removal, or a groove can be provided at the outer end of the drill rod body 1 to facilitate the removal of the receiving plate 6 from the slide groove 13.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the cross-section of the receiving plate 6 at one end within the slide groove 13 is T-shaped. This design prevents the receiving plate 6 from detaching from the slide groove 13.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, a protective ring 3 is slidably connected to the outer side of the assembly joint 2, and the protective ring 3 is threadedly connected to the outer side of the drill pipe body 1.

[0033] like Figure 5 As shown, the outer wall of the assembly joint 2 is fixedly connected with two symmetrically arranged limiting rings 7, and the inner wall of the protective ring 3 is provided with a moving groove 31 corresponding to the limiting rings 7.

[0034] Specifically, after the drill rod body 1 has been installed, the protective ring 3 can be rotated to make the protective ring 3 threadedly connected to the outer wall of the drill rod body 1. At the same time, the limiting ring 7 can prevent the moving groove 31 from disengaging. This setting can strengthen the connection between the two drill rod bodies and the end rod 4, making the connection more stable.

[0035] like Figure 3 and Figure 5 As shown, compression pads 8 are fitted on both sides of the outer wall of the assembly joint 2, and the outer wall of the compression pads 8 abuts against the end of the drill rod body 1. With this arrangement, when the end rod 4 is connected to the assembly groove 11, the compression pads 8 make the mating surfaces more tightly connected.

[0036] like Figure 4 As shown, the outer wall of the assembly joint 2 has two symmetrically arranged tool slots 21. The tool slots 21 facilitate the rotation and disassembly of the assembly joint 2.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
