However, this process requires a large force to generate sufficient force component to break the core, which will generate large vibrations and noise, affecting the construction environment.
[0005] Therefore, it is necessary to provide a core breaking tool for a rotary drilling rig to solve the above technical problems. Utility Model Content
[0006] The technical problem to be solved by the present invention is that a large force is required to generate sufficient component force to break the core, and large vibration and noise will be generated in the process. In view of the above-mentioned defects of the prior art, a core breaking tool for a rotary drilling rig is provided.
[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a core breaking tool for a rotary drilling rig includes a mounting plate, a sliding groove is provided at the bottom of the mounting plate, and a sliding column is slidably connected inside the sliding groove. There are four sliding columns, two of which are connected to the first plug column at the bottom through pins, and the bottoms of the remaining two sliding columns are connected to the second plug column through pins, and the second plug column is arranged in a conical structure.
[0008] By adopting the above technical solution, the core breaking tooling for rotary drilling rigs can realize flexible adjustment of the sliding column position. The sliding groove at the bottom of the mounting plate allows the sliding column to slide freely therein. In this way, the operator can adjust the position of the sliding column according to actual needs to ensure that the tooling is precisely aligned with the center position of the groove opened by the rotary drilling rig, thereby improving the accuracy and efficiency of the operation.
[0009] It is further provided that the interior of the mounting plate is rotatably connected to a rotating plate, a guide groove is provided on the rotating plate, and the guide groove is slidably connected to the sliding column.
[0010] By adopting the above technical solution, the rotating disk added inside the mounting plate provides a more convenient and accurate way to adjust the position of the sliding column. The guide groove on the rotating disk is slidably connected to the sliding column. In this way, the operator can easily adjust the position of the sliding column in the sliding groove by simply rotating the rotating disk.
[0011] It is further provided that a push rod is fixedly connected to one side of the rotating disk, and locking grooves are provided around the rotating disk.
[0012] By adopting the above technical solution, the push rod fixedly connected to one side of the rotating disk provides the operator with a more convenient and direct adjustment method. The operator can easily rotate the rotating disk and adjust the position of the sliding column by simply pushing or pulling the push rod.
[0013] It is further provided that a plurality of locking grooves are provided, and the plurality of locking grooves are evenly arranged in a ring shape along the central axis of the rotating disk.
[0014] By adopting the above technical solution, since the locking grooves are evenly arranged in a ring shape along the central axis of the rotating disk, no matter which position the rotating disk is rotated to, the operator can find the corresponding locking groove for locking.
[0015] It is further provided that locking bolts are threadedly connected around the four sides of the mounting plate, and three locking bolts are provided.
[0016] By adopting the above technical solution, when the rotating disk is rotated to the desired position and aligned with the locking groove, the operator can tighten the locking bolt to firmly lock it on the mounting disk.
[0017] It is further provided that a connecting block is fixedly connected to the top of the mounting plate, and a pin groove for connection is provided on the connecting block.
[0018] By adopting the above technical solution, the connecting block fixedly connected to the top of the mounting plate provides a stable connection point for the tooling. The connecting block serves as a bridge between the tooling and the rotary drilling rig, ensuring that the tooling can be firmly connected to the rotary drilling rig, thereby maintaining a stable posture and position during operation.
[0019] It is further provided that the bottoms of the remaining two sliding columns are connected to a third plug column via a pin, and the third plug column is provided in a trapezoidal structure.
[0020] By adopting the above technical solution, the third column connected by pins at the bottom of the other two sliding columns provides the tooling with additional core breaking ability. The third column is arranged in a trapezoidal structure, so that the third column can gradually expand the contact area with the rock core when inserted into the rock core, thereby more effectively transmitting the breaking force. When the tooling is rotated and inserted downward, the third column works together with the first column and the second column to generate a greater shaking force on the rock core, which helps to quickly break the bottom of the rock core.
[0021] Compared with the related art, the core breaking tool for rotary drilling rig provided by the utility model has the following beneficial effects:
[0022] The utility model provides a core breaking tool for a rotary drilling rig. By arranging a first plug post and a second plug post, when the tool is rotated and inserted downward, the second plug post with a conical structure and the first plug post cooperate with each other to generate a continuous shaking force on the core. The effect of this shaking force is to gradually break the bottom of the core. Compared with the traditional method of using a large force to directly break the core, the utility model is more gentle and effective, can reduce the vibration generated during the operation, and protect the integrity of the core.
[0023] The utility model provides a core breaking tool for a rotary drilling rig, which adopts the arrangement of a third plug post to reduce the cutting resistance of soil and the like during cutting. The front end of the trapezoidal structure is provided with an inclined groove, which can more effectively guide soil and gravel, so that the resistance encountered by the third plug post during the insertion process is greatly reduced, thereby improving the insertion efficiency and smoothness of the tool. After the trapezoidal third plug post is inserted into the rock core, its unique shape can generate an effective shaking force on the rock core. When the tool rotates and inserts downward, the trapezoidal third plug post works together with the first plug post and the second plug post to gradually break the bottom of the rock core by shaking the rock core. Compared with the traditional direct breaking, it is more gentle and effective, and can reduce the vibration and noise generated during the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.
[0031] Example 1:
[0032] like Figure 1-5 When the tool is rotated and inserted downward, the first plug post 14 and the second plug post 5 can be easily inserted into the gap. These plug posts will generate a continuous shaking force on the core, and the effect of this shaking force is to gradually break the bottom of the core. Compared with the traditional method of using a large force to directly break the core, this shaking and breaking method is more gentle and effective, and can significantly reduce the vibration and noise generated during the operation, thereby optimizing the construction environment, reducing the health threat to construction site workers, and reducing interference with the surrounding environment.
[0033] like Figure 2 The internal rotation of the mounting plate 1 is connected to the rotating plate 6, and a guide groove 7 is opened on the rotating plate 6. The guide groove 7 is slidably connected to the sliding column 3. Since the rotating plate 6 can rotate freely relative to the mounting plate 1, no matter what the size of the groove opened by the rotary drilling machine is, the operator can adjust the position of the sliding column 3 by rotating the rotating plate 6 to ensure that the tooling is aligned with the center position of the groove.
[0034] like Figure 1 、 Figure 2 and Figure 3 A push rod 8 is fixedly connected to one side of the rotating disk 6, and a locking groove 9 is opened around the rotating disk 6. When the rotating disk 6 is rotated to the desired position, the operator can screw the locking bolt 10 into the locking groove 9 to firmly lock the rotating disk 6 on the mounting disk 1, ensuring the stability of the rotating disk 6 during operation, and preventing position deviation or shaking caused by loosening of the rotating disk 6, thereby improving the operation accuracy and safety of the tooling.
[0035] like Figure 1 、 Figure 2 and Figure 3 There are multiple locking grooves 9, and the multiple locking grooves 9 are evenly arranged in a ring shape along the central axis of the rotating disk 6. The uniform arrangement of the multiple locking grooves 9 also enhances the adaptability and versatility of the tooling. In different construction environments, the operator can choose different locking grooves 9 for locking according to actual needs to ensure that the tooling is aligned with the center position of the groove opened by the rotary drilling rig.
[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The mounting plate 1 is threadedly connected with locking bolts 10 around it. There are three locking bolts 10. The three locking bolts 10 also enhance the stability and reliability of the tooling. The three locking bolts 10 are distributed in a triangular shape, which can evenly withstand the force and vibration generated by the rotating plate 6 and the sliding column 3 during operation.
[0037] like Figure 1 A connecting block 11 is fixedly connected to the top of the mounting plate 1, and a pin groove 12 for connection is provided on the connecting block 11. The pin groove 12 provided on the connecting block 11 provides a convenient way for installation and disassembly of the tooling. The operator only needs to insert the pin of the rotary drilling rig into the pin groove 12 to easily connect the tooling to the rotary drilling rig, which simplifies the installation and disassembly process and improves the usability and maintainability of the tooling.
[0038] During implementation: First, the connecting block 11 is connected to the rotary drilling machine with the pin groove 12, and then the position of the rotating disk 6 is adjusted by the push rod 8, and then the sliding column 3 is driven to slide on the sliding groove 2 through the guide groove 7, so that the position of the sliding column 3 at the bottom can be adjusted to ensure that it can be aligned with the center position of the groove opened by the rotary drilling machine, and then the locking bolt 10 is tightened so that it can be inserted into the inside of the lock groove 9, and then the rotary drilling machine is started to rotate the tooling, and then inserted downward. At this time, the second plug column 5 and the first plug column 4 of the conical structure cooperate to continuously generate a shaking force on the core, and then the bottom of the core is broken by shaking the core.
[0039] Example 2:
[0040] like Figure 5 As shown, based on the first embodiment, the utility model provides a technical solution: the bottoms of the other two sliding columns 3 are connected to the third plug column 13 by pins, and the third plug column 13 is arranged in a trapezoidal structure. During the insertion of the core, the inclined surface on one side of the trapezoidal structure can quickly cut into the gap to prevent the tooling from slipping or shaking due to force, thereby ensuring the safety and reliability of the tooling during operation and improving the success rate and efficiency of breaking the core.
[0041] During implementation: First, by using the trapezoidal third plug 13 with an inclined groove, the cutting resistance of the soil and the like can be reduced during cutting. At the same time, the trapezoidal third plug 13 can also generate a shaking force on the core, thereby breaking the bottom of the core by shaking the core.
[0042] The advantages of this technical solution in practical applications include but are not limited to the following:
[0043] 1. The function of shaking force is to gradually break the bottom of the core. Compared with the traditional method of directly breaking the core with great force, it is more gentle and effective, and can reduce the vibration generated during the operation;
[0044] 2. The front end of the trapezoidal structure is equipped with an inclined groove, which can more effectively guide the soil and gravel. In an environment where soil and gravel slide and are buried, the resistance encountered by the third plug during insertion is greatly reduced, thereby improving the efficiency and smoothness of the tooling insertion.
[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
