Abstract
Description
Technical Field
[0001] This utility model relates to the field of drill bit technology, specifically to a drill bit transportation protection device for oil drilling. Background Technology
[0002] In oil drilling operations, the drill bit, as a core component, has a precise structure and is expensive. During transportation, it is crucial to avoid damage to the cutting edge or loosening of connections due to vibration or impact. Existing transportation protection devices generally suffer from the following problems:
[0003] Limited clamping methods: mostly using fixed slots or rigid clamps, which cannot meet the clamping requirements of drill bits of different sizes, and rigid contact can easily cause wear on the drill bit surface;
[0004] Insufficient cushioning performance: Traditional devices rely on a single spring or foam pad for cushioning, which has limited effect on absorbing multidimensional vibrations in complex transportation environments, and especially lacks differentiated cushioning designs for vertical and lateral impacts.
[0005] Low level of automation: The clamping process requires manual operation of fasteners (such as bolts and clips), which is time-consuming and labor-intensive, and it is difficult to ensure uniform clamping force, which poses a risk of the drill bit loosening during transportation;
[0006] Poor structural stability: The guiding mechanism of some devices is not precise enough, and it is easy to deviate during clamping. After long-term use, it may fail to clamp due to wear.
[0007] To address the aforementioned problems, this utility model provides a protective device for transporting drill bits in oil drilling. Through a clamping assembly linked to the box cover, a double buffer structure, and a high-precision guiding system, it achieves adaptive clamping and multi-dimensional protection of the drill bit. This device requires no additional power source, completing clamping through mechanical linkage. It combines buffering performance with structural stability, effectively solving the shortcomings of inflexible clamping and incomplete protection in existing technologies. It meets the high reliability requirements of oil drilling equipment in complex transportation environments and has significant engineering application value. Utility Model Content
[0008] The purpose of this invention is to provide a protective device for transporting drill bits in oil drilling, so as to solve the problems mentioned in the background art.
[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0010] A protective device for transporting drill bits in oil drilling includes a protective box, a receiving base fixedly connected to the bottom of the inner wall of the protective box, and a box cover movably inserted into the top of the protective box.
[0011] The inner wall of the protective box is provided with a clamping assembly, which includes a vertical guide rail. A vertical sliding block is slidably connected to the inner wall of the vertical guide rail. An oblique connecting rod is hinged to one side of the vertical sliding block. A fixed oblique rod is rotatably connected to the bottom end of the oblique connecting rod. A horizontal sliding base is fixedly connected to the bottom end of the fixed oblique rod. A transverse guide rail is slidably connected to the outer wall of the horizontal sliding base. An arc plate slider is fixedly connected to the end of the fixed oblique rod away from the horizontal sliding base. A clamping arc plate is slidably connected to the outer wall of the arc plate slider.
[0012] A further improvement of this utility model is that: a vertical guide groove is provided on the outer arc surface of the clamping arc plate, and the inner wall of the vertical guide groove is slidably connected to the outer wall of the arc plate slider.
[0013] A further improvement of this utility model is that: an arc block spring is fixedly connected to the top of the arc plate slider, and the top end of the arc block spring is fixedly connected to the top of the inner wall of the vertical guide groove.
[0014] A further improvement of this utility model is that a downward pressure rod is fixedly connected to the top of the vertical sliding slider, and one end of the horizontal guide rail is fixedly connected to one side of the vertical guide rail.
[0015] A further improvement of this utility model is that a rubber protrusion is fixedly connected to the inner arc surface of the clamping arc plate.
[0016] A further improvement of this utility model is that: a pressure spring is fixedly connected to the bottom end of the vertical sliding slider, and the bottom end of the pressure spring is fixedly connected to the bottom of the inner wall of the vertical guide rail.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides a protective device for transporting drill bits in oil drilling, featuring an adaptive clamping mechanism: through the linkage design of the cover and the lower pressure rod, the clamping components are automatically triggered. When the cover is closed, the clamping arc plate can be driven to move synchronously without additional operation, quickly clamping the drill bit. The clamping force is automatically adjusted according to the degree of cover closure, adapting to drill bits of different sizes and improving the device's versatility.
[0019] 2. This utility model provides a protective device for transporting drill bits used in oil drilling, featuring a dual-buffer structure for enhanced protection: an arc-shaped spring and a pressure spring provide vertical and lateral buffering effects respectively, forming a three-dimensional buffer system. During transportation, it can effectively absorb the vibration energy generated by road bumps and collisions, preventing the drill bit from experiencing edge wear or structural damage due to rigid impacts, thus significantly improving the protective effect.
[0020] 3. This utility model provides a protective device for transporting drill bits for oil drilling, which provides flexible contact protection for the drill bit surface: the rubber protrusions on the inner arc surface of the clamping arc plate achieve anti-slip fixation of the drill bit through flexible contact, avoiding scratches or stress concentration caused by direct contact between traditional metal clamping parts and the drill bit, and is especially suitable for the transport protection of high-precision drill bits.
[0021] 4. This utility model provides a protective device for transporting drill bits for oil drilling. The guide sliding structure is stable and reliable: the cooperation between the vertical guide rail and the horizontal guide rail ensures that the vertical sliding block and the fixed inclined rod move in the predetermined direction, avoiding deviation or jamming during the clamping process, and improving the stability of the mechanism's movement and the clamping accuracy.
[0022] 5. This utility model provides a protective device for transporting drill bits for oil drilling. The modular design facilitates maintenance: the base provides a support benchmark for the drill bit, the plug-in structure between the cover and the protective box facilitates quick opening and closing, and all sliding parts of the clamping assembly (such as vertical sliding block and arc plate sliding block) adopt a standardized design, which facilitates later maintenance and replacement and reduces the cost of use.

[0029] The present invention will be further described in detail below with reference to embodiments:
[0030] Example 1
[0031] like Figure 1-4 As shown, this utility model provides a protective device for transporting drill bits for oil drilling, including a protective box 1, a receiving base 4 fixedly connected to the bottom of the inner wall of the protective box 1, and a box cover 2 movably inserted into the top of the protective box 1.
[0032] The inner wall of the protective box 1 is provided with a clamping assembly 3, which includes a vertical guide rail 5. A vertical slider 6 is slidably connected to the inner wall of the vertical guide rail 5. An oblique connecting rod 9 is hinged to one side of the vertical slider 6. A fixed oblique rod 11 is rotatably connected to the bottom end of the oblique connecting rod 9. A horizontal base 18 is fixedly connected to the bottom end of the fixed oblique rod 11. A transverse guide rail 10 is slidably connected to the outer wall of the horizontal base 18. An arc plate slider 16 is fixedly connected to the end of the fixed oblique rod 11 away from the horizontal base 18. A clamping arc plate 12 is slidably connected to the outer wall of the arc plate slider 16.
[0033] The outer arc surface of the clamping arc plate 12 is provided with a vertical guide groove 14, and the inner wall of the vertical guide groove 14 is slidably connected to the outer wall of the arc plate slider 16.
[0034] Example 2
[0035] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an arc block spring 17 is fixedly connected to the top of the arc plate slider 16, and the top end of the arc block spring 17 is fixedly connected to the top of the inner wall of the vertical guide groove 14.
[0036] The top of the vertical slider 6 is fixedly connected to the pressure rod 7, and one end of the horizontal guide rail 10 is fixedly connected to one side of the vertical guide rail 5.
[0037] A rubber protrusion 13 is fixedly connected to the inner arc surface of the clamping arc plate 12, and a pressure spring 8 is fixedly connected to the bottom end of the vertical sliding slider 6. The bottom end of the pressure spring 8 is fixedly connected to the bottom of the inner wall of the vertical guide rail 5.
[0038] The working principle of this oil drilling bit transport protection device will be explained in detail below.
[0039] like Figure 1-4As shown, when using this oil drilling bit transport protection device, the drill bit is first placed on the receiving base 4 inside the protection box 1, and then the box cover 2 is aligned with the top of the protection box 1. During the pressing down process, the box cover 2 contacts the top of the pressing rod 7 and applies pressure, causing the vertical sliding block 6 to slide downward within the vertical guide rail 5. When the vertical sliding block 6 moves downward, it pushes the fixed inclined rod 11 to move through the hinged oblique connecting rod 9. Since the horizontal base 18 at the bottom of the fixed inclined rod 11 is slidably connected to the horizontal guide rail 10, and the oblique connecting rod 9 and the fixed inclined rod 11 are V-shaped hinged, the fixed inclined rod 11 moves laterally along the horizontal guide rail 10 towards the center of the protection box 1 after being pushed.
[0040] The arc-shaped slider 16 at the top of the fixed inclined rod 11 is embedded in the vertical guide groove 14 on the outer arc surface of the clamping arc plate 12. As the fixed inclined rod 11 moves laterally, it drives the clamping arc plates 12 on both sides to move synchronously towards the center until the rubber protrusion 13 on the inner arc surface fits against the outer wall of the drill bit, thus achieving clamping and fixing of the drill bit. During the clamping process, if the drill bit experiences vertical displacement due to transportation vibration, the arc-shaped spring 17 at the top of the arc-shaped slider 16 can absorb vibration energy through compression or stretching, providing vertical buffering. At the same time, the bearing spring 8 at the bottom of the vertical sliding slider 6 is compressed when the vertical sliding slider 6 moves downward. When a lateral impact occurs during transportation, the elastic deformation of the bearing spring 8 can offset the lateral impact force, providing lateral buffering protection for the clamping arc plate 12. The rubber protrusion 13 increases the friction during clamping, preventing the drill bit from slipping, while its flexible material avoids surface damage caused by hard contact.
[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
