Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a drilling rig threaded sleeve reversing soil cleaning device. Background Technology

[0002] In soil pollution investigations and groundwater monitoring operations, drilling equipment needs to construct monitoring wells by embedding threaded casings to stabilize the well walls. During drilling, soil particles easily become embedded in the threads of the casing, forming a stubborn deposit layer. This deposit not only hinders the normal tightening and loosening of the casing but also significantly reduces drilling efficiency, becoming a key issue restricting the continuity of environmental investigation operations.

[0003] Currently, the main method for cleaning threaded casing is manual cleaning, which has the following inherent drawbacks: manual scraping requires machine shutdown, interrupting the continuous drilling process and significantly extending the operation cycle; operators need to be close to the rotating parts of the drilling rig, which poses a high risk of mechanical injury and impact from flying debris; manual operation is limited by the size of the working face and cannot be carried out in narrow or complex terrain; the additional manpower input and equipment downtime lead to a significant increase in operation and maintenance costs. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies, such as low efficiency, high safety risks, poor spatial adaptability, and high maintenance costs in manually cleaning threaded casings, by providing a reverse soil cleaning device for drilling rig threaded casings.

[0005] The technical solution adopted by this utility model is as follows: a drilling rig threaded casing reversing soil cleaning device, including a drilling rig body, a drilling rig column installed on one side of the drilling rig body, a casing control device and a threaded casing installed on one side of the drilling rig column, the casing control device being used to drive the threaded casing to rotate in the reverse direction at a low speed during the drilling rig lifting process, the drilling rig column and the threaded casing being connected by a soil stripping baffle assembly, the soil stripping baffle assembly being composed of a robotic arm rear arm, a horizontal adjustment plate, a robotic arm front arm, and a baffle, the root of the robotic arm rear arm being fixed to the drilling rig column by a locking device, the horizontal adjustment plate being fixed to the head of the robotic arm rear arm by bolts, the tail of the robotic arm front arm being connected to the horizontal openings on both sides of the horizontal adjustment plate by bolts and being movable along the horizontal openings to adjust the horizontal position, the baffle being detachably connected to the head of the robotic arm front arm by a magnetic insertion device.

[0006] As a further improvement of this utility model, the front section of the baffle is provided with a hollow structure, and the arc-shaped working surface of the baffle is configured to fit against the outer wall of the threaded sleeve, and engages with the thread in the reverse direction to peel off the attached soil when the threaded sleeve rotates in the opposite direction.

[0007] As a further improvement of this utility model, the magnetic insertion device includes an insertion plate welded to the back of the baffle and a magnet disposed at the head of the forearm of the robotic arm. The insertion plate is fastened to the forearm of the robotic arm by magnetic attraction.

[0008] As a further improvement of this utility model, the width of the baffle is adapted to the outer diameter of the threaded sleeve, and the width range is 120-150mm.

[0009] As a further improvement of this utility model, the center of the horizontal adjustment plate is provided with a longitudinal bolt hole for fixing the head of the rear arm of the robotic arm; horizontal strip-shaped openings are symmetrically opened on both sides for adjusting the horizontal installation position of the front arm of the robotic arm.

[0010] As a further improvement of this utility model, the locking device is an adjustable clamp, configured to lock and fix the root of the robotic arm's rear arm to drilling rig columns of different diameters.

[0011] The beneficial effects of this utility model are as follows: This utility model achieves a technological leap from manual intervention to full automation in the cleaning operation of threaded casing through the coordinated control of reverse drive and adaptive baffle assembly: During the lifting process of threaded casing, it is driven by a bidirectional motor to rotate in the reverse direction at low speed. At the same time, the horizontal / vertical dual-degree-of-freedom adjustable robotic arm precisely controls the arc surface of the baffle to fit against the outer wall of the casing, and automatically peels off the soil attached to the thread gap by using the reverse meshing action.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 The drill rig threaded casing reversing soil removal device shown includes a drill rig body 1, a drill rig column 5 installed on one side of the drill rig body 1, a casing control device 6 and a threaded casing 7 installed on one side of the drill rig column 5. The casing control device is used to drive the threaded casing 7 to rotate in the reverse direction at a low speed during the drilling rig lifting process. The drill rig column 5 and the threaded casing 7 are connected by a soil stripping baffle assembly. The soil stripping baffle assembly consists of a mechanical arm rear arm 3, a horizontal adjustment plate 8, a mechanical arm front arm 4, and a baffle 10. The root of the mechanical arm rear arm 3 is fixed to the drill rig column 5 by a locking device 2. The horizontal adjustment plate 8 is fixed to the head of the mechanical arm rear arm 3 by bolts 9. The tail of the mechanical arm front arm 4 is connected to the horizontal openings on both sides of the horizontal adjustment plate 8 by bolts 9 and can move along the horizontal openings to adjust the horizontal position. The baffle 10 is detachably connected to the head of the mechanical arm front arm 4 by a magnetic insertion device 11.

[0021] like Figure 2 and Figure 3 As shown, the front section of the baffle 10 in this utility model has a hollow structure. The arc-shaped working surface of the baffle 10 is configured to fit against the outer wall of the threaded sleeve 7, and engages with the thread in the reverse direction to peel off the attached soil when the threaded sleeve 7 rotates in the opposite direction. This allows for more precise action on the stubborn attached layer in the thread gap during the soil cleaning process, thereby improving the soil cleaning effect.

[0022] like Figure 4As shown, the magnetic insertion device 11 of this utility model includes an insertion plate 12 welded to the back of the baffle 10 and a magnet 13 disposed at the head of the robotic arm forearm 4. The insertion plate 12 is fastened to the robotic arm forearm 4 by magnetic attraction, which not only ensures the stability of the baffle 10 installation, but also facilitates quick disassembly when the baffle 10 needs to be replaced or maintained.

[0023] In this utility model, the width of the baffle 10 is adapted to the outer diameter of the threaded sleeve 7, with a width range of 120-150mm. This allows it to cover a large area of ​​the threaded sleeve 7 while ensuring a good fit with the threaded sleeve 7, thereby further improving soil removal efficiency.

[0024] like Figure 2 and Figure 3 As shown, the horizontal adjustment plate 8 of this utility model has a longitudinal bolt hole in the center for fixing the head of the rear arm 3 of the robotic arm; horizontal strip openings are symmetrically opened on both sides for adjusting the horizontal installation position of the front arm 4 of the robotic arm, so that the front arm 4 of the robotic arm can be flexibly adjusted according to different operation requirements to adapt to different threaded sleeve 7 installation conditions and soil cleaning operation scenarios.

[0025] like Figure 2 and Figure 3 As shown, the locking device 2 in this utility model is an adjustable clamp, configured to lock and fix the root of the robotic arm rear arm 3 to the drilling rig column 5 of different diameters, which enhances the versatility and adaptability of the device and can be used on a variety of drilling rigs of different specifications.

[0026] Working Principle: In practical implementation, when the drilling rig begins lifting operations, the casing control device 6 drives the threaded casing 7 to rotate in the opposite direction at a low speed. Simultaneously, the operator can adjust the horizontal position of the robotic arm forearm 4 through the horizontal strip openings on both sides of the horizontal adjustment plate 8, based on the outer diameter and installation position of the threaded casing 7, ensuring that the arc-shaped working surface of the baffle 10 precisely fits against the outer wall of the threaded casing 7. Because the arc-shaped working surface of the baffle 10 engages with the threads of the threaded casing 7 in the opposite direction, the baffle 10 continuously peels away the soil adhering to the threads during the reverse rotation of the threaded casing 7. As the drilling rig continues to lift, the threaded casing 7 continues to rotate in the opposite direction, and the soil adhering to the threads is continuously peeled off by the baffle, achieving the purpose of soil removal.

[0027] During operation, if the baffle 10 needs to be replaced or maintained, thanks to the magnetic insertion device 11, the operator only needs to apply a certain external force to overcome the magnetic attraction, and the baffle 10 can be quickly removed from the robotic arm front arm 4 for operation. The adjustable locking device 2 allows the robotic arm rear arm 3 to be securely installed on drilling rig columns 1 of different diameters, ensuring that the device can be used normally on various drilling rigs of different specifications. This greatly improves the versatility and applicability of the device, effectively solving the problems of low efficiency, high safety risks, poor spatial adaptability, and high maintenance costs associated with manual cleaning of threaded sleeves 7 in existing technologies. It provides an efficient, safe, and reliable soil cleaning solution for drilling work in soil pollution investigation and groundwater monitoring operations.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
