Description

Technical Field

[0001] This utility model relates to the field of lifting ring technology, and more specifically, to a drilling lifting ring that prevents disengagement. Background Technology

[0002] In oil and gas drilling, heavy objects such as drill pipes and casing need to be lifted and lowered. The drilling ring, a key component connecting the overhead crane and traveling block, bears the weight of the entire hoisting system and various dynamic loads during drilling. It is crucial for the accurate vertical movement of drill strings and other heavy objects within the wellhead. In conjunction with other hoisting equipment, the drilling ring precisely controls the position of the drill string, ensuring the smooth progress of drilling operations.

[0003] There are many existing technologies for lifting rings, such as:

[0004] According to Chinese patent application number CN202421040751.1, specifically a lifting ring includes a pull ring with an inner hole and a bolt for connecting to a heavy object. The pull ring includes a ring body and a ring seat, with the inner hole formed between the ring body and the ring seat. A rotating hole is formed on the ring seat for the bolt to pass through. The bolt rotates with the rotating hole, restricting their opposite movement. A locking component is provided on the ring seat to engage with the pull ring. The locking component has a locked state that fixes the pull ring and the ring seat, and an unlocked state that allows them to separate. A linkage component is provided between the bolt and the locking component to control the locking component. When the bolt is in the rotating hole, the bolt controls the locking component to be in the locked state through the linkage component; when the bolt leaves the rotating hole, the bolt controls the locking component to be in the unlocked state through the linkage component. This utility model has the following advantages and effects: It enables convenient assembly and disassembly, thereby reducing the complexity and workload of operation and improving lifting efficiency.

[0005] Currently, most drilling lifting rings on the market use traditional pin or bolt connections. While pin connections are simple in structure, the pins are prone to loosening under large lateral forces or impacts, causing the lifting ring to disengage. Although bolt connections offer higher connection strength, bolts are susceptible to corrosion and fatigue fracture under prolonged operation in harsh environments, leading to disengagement. Once disengagement occurs, it can cause serious accidents such as drill string falling, resulting in huge economic losses and potentially endangering the lives of workers. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an anti-disengagement drilling ring, which solves the problem that traditional drilling rings are prone to disengagement under complex working conditions, easily leading to equipment damage, work interruption, huge economic losses, and more seriously threatening the lives of on-site workers.

[0007] To achieve the above objectives, this utility model provides a drilling ring with anti-disengagement features, including a main locking assembly. The main locking assembly includes a rotating component, with a first threaded rod fixedly connected to the bottom of the rotating component. The first threaded rod is threadedly connected to an external connector. A secondary locking assembly is provided inside the main locking assembly, and the secondary locking assembly is secondaryly connected and fixed to the external connector. Mounting blocks are symmetrically arranged on the outer side of the main locking assembly, and the two mounting blocks are rotatably connected to the rotating component. A ring is provided on the top of each mounting block.

[0008] The beneficial effects of this utility model are:

[0009] 1. When installing the lifting ring and external connectors, the main locking assembly quickly and stably installs the lifting ring in the required position. Then, the secondary locking assembly is used to connect and fix it to the external connectors, forming a double lock. This effectively prevents the lifting ring from disengaging due to displacement in different directions during the stress process. It can effectively reduce economic losses such as equipment damage and work stoppage caused by disengagement accidents, and can ensure the continuity and stability of drilling operations.

[0010] 2. During use, the lifting ring can rotate in multiple directions to meet the needs of different drilling and lifting operations. The buffer pad absorbs and disperses the impact force, reduces the instantaneous stress on the connection parts, reduces the risk of disengagement, and extends the service life of the lifting ring, reducing the frequency of replacement and maintenance costs.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, the rotating component and the first threaded rod are provided with a first sliding groove, the first threaded rod is symmetrically provided with a second sliding groove, the lower end of the first threaded rod is provided with a groove, the lower end of the groove is provided with a threaded groove, the secondary locking assembly includes a sliding rod, the sliding rod slides inside the second sliding groove, a connecting plate is fixedly connected to one bottom end of the sliding rod, a spring is symmetrically fixedly connected between one side of the connecting plate and one side inside the groove, an insert rod is slidably connected inside the first sliding groove, a protrusion is symmetrically fixedly connected to the lower end of one side of the insert rod, the protrusion presses against the two connecting plates when placed in the groove, the insert rod is threadedly connected to the threaded groove through threaded teeth, and a limit block is symmetrically fixedly connected to the upper end of one side of the insert rod.

[0013] The beneficial effects of adopting the above-mentioned further solution are that it forms a double locking structure, increases the force-bearing area between the lifting ring and the external connector, increases the stability of the lifting ring connection, increases the anti-derailment effect of the lifting ring, and has a simple structure, is easy to operate, and facilitates the installation and disassembly of the lifting ring.

[0014] Preferably, a fixing plate is symmetrically fixedly connected to one side of the mounting block, and the fixing plates on the two mounting blocks are fixedly connected by a fastener. A second threaded rod is threadedly connected to one side of the inside of the mounting block, and a rotating cylinder is fixedly connected to both ends of the ring. The rotating cylinder rotates outside the second threaded rod.

[0015] The advantage of adopting the above-mentioned further solution is that it makes the connection between the components of the lifting ring more flexible, and when the components of the lifting ring are damaged after long-term use, it is easy to quickly maintain and replace each component individually, thereby reducing the cost of use.

[0016] Preferably, buffer pads are fixedly connected to both the outer side of the rotating component and the inner side of the rotating cylinder.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the lifting ring is subjected to impact load, the buffer pad can absorb and disperse the impact force, reduce the instantaneous stress on the connection part, reduce the risk of disengagement, and extend the service life of the lifting ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The main locking assembly quickly and stably installs the lifting ring in the required position, and then the secondary locking assembly secures it to the external connector, forming a double lock. This effectively prevents the lifting ring from disengaging due to displacement in different directions during the stress process, thus effectively reducing economic losses such as equipment damage and downtime caused by disengagement accidents. It ensures the continuity and stability of drilling operations, reduces downtime caused by equipment failure, and improves drilling efficiency, thereby bringing more economic benefits to the enterprise. In addition, the connection between the various components of the lifting ring is relatively flexible, and when the lifting ring is damaged after long-term use, it is easy to maintain and replace each component individually, reducing the cost of use.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 As shown, this embodiment provides a drilling eye anti-disengagement device, including a main locking assembly 1. The main locking assembly 1 includes a rotating part 11, and a first threaded rod 12 is fixedly connected to the bottom of the rotating part 11. The first threaded rod 12 is threadedly connected to an external connecting part. Considering that traditional drilling eyelets mostly use traditional pin or bolt connections, although bolt connections have high connection strength, they are prone to corrosion and fatigue fracture under harsh environments for a long time, which can easily lead to disengagement. Therefore, a secondary locking assembly 2 is provided inside the main locking assembly 1. The secondary locking assembly 2 is connected to an external connecting part. The connecting parts are fixed by secondary connection. Even if the bolts are worn, they can still be stably connected to the external connecting parts through the secondary locking component 2 to form a double lock. This effectively prevents the lifting ring from disengaging due to displacement in different directions during the stress process. It can effectively reduce economic losses such as equipment damage and work stoppage caused by disengagement accidents, and can ensure the continuity and stability of drilling operations. The main locking component 1 is symmetrically provided with mounting blocks 3 on the outside. The two mounting blocks 3 are rotatably connected to the rotating part 11. The top of the mounting block 3 is provided with a ring 4 to increase the flexibility of the ring 4 and meet the needs of different drilling and lifting operations.

[0033] The improvement of this embodiment lies in the following: the main locking component 1 quickly and stably installs the lifting ring in the required position, and then the secondary locking component 2 is used to connect and fix it to the external connector, forming a double lock. This effectively prevents the lifting ring from disengaging due to displacement in different directions during the stress process, increases the stress-bearing area between the lifting ring and the external connector, and can effectively reduce economic losses such as equipment damage and work stoppage caused by disengagement accidents. It can ensure the continuity and stability of drilling operations. In addition, the connection between the components of this lifting ring is relatively flexible. When the lifting ring is damaged after long-term use, it is easy to maintain and replace each component individually, reducing the cost of use.

[0034] Specifically, considering the ease of connection between the lifting ring and the external connector, and to ensure the stability of the connection between the main locking assembly 1 and the external connector, a first groove 13 is provided inside the rotating part 11 and the first threaded rod 12. A second groove 14 is symmetrically provided inside the first threaded rod 12. A groove 15 is provided at the lower end of the first threaded rod 12, and a threaded groove 16 is provided at the lower end of the groove 15. The secondary locking assembly 2 includes a sliding rod 21, which slides inside the second groove 14. A connecting plate 22 is fixedly connected to one bottom end of the sliding rod 21. A spring 23 is symmetrically fixedly connected between one side of the connecting plate 22 and one side inside the groove 15. An insert rod 24 is slidably connected inside the first groove 13. A protrusion 25 is symmetrically fixedly connected to the lower end of one side of the insert rod 24. When the protrusion 25 is placed in the groove 15, it presses against the two connecting plates 22. During installation, the sliding rod 21 retracts inside the second groove 14 due to the elastic force of the spring 23. At this time, the lifting ring is first threadedly connected to the external connector through the first threaded rod 12. The installation position of the lifting ring is determined, and a preliminary connection and locking is made with the external connector. Then, the insert rod 24 is inserted into the first slide groove 13. The protrusion 25 at the bottom of the insert rod 24 squeezes the connecting plate 22 and the spring 23. At this time, the two sliding rods 21 slide outward in the second slide groove 14 and engage with the external connector for secondary connection and locking. This increases the force-bearing area of ​​the connection between the lifting ring and the external connector, effectively preventing the lifting ring from disengaging due to displacement in different directions during the force process. Then, the insert rod 24 is rotated, and the insert rod 24 is threadedly connected to the threaded groove 16 through the threaded teeth 26, locking the position of the insert rod 24 and ensuring a stable connection between the sliding rod 21 and the external connector. A limit block 27 is symmetrically fixedly connected to the upper end of one side of the insert rod 24. The limit block 27 is perpendicular to the fixed direction of the protrusion 25. By determining the direction of the limit block 27, the protrusion 25 can be stably contacted with the connecting plate 22, ensuring the squeezing effect of the protrusion 25 on the connecting plate 22, and thus ensuring the engaging connection effect between the sliding rod 21 and the external connector.

[0035] Considering that the connections between traditional lifting ring components are relatively fixed, if some components are damaged, the entire lifting ring needs to be replaced, increasing the cost of using the lifting ring. Therefore, a fixing plate 31 is symmetrically fixedly connected to one side of the mounting block 3. The fixing plates 31 on the two mounting blocks 3 are fixedly connected to each other by a fastener 32. A second threaded rod 33 is threadedly connected to one side of the inside of the mounting block 3. Rotating cylinders 41 are fixedly connected to both ends of the ring 4. The rotating cylinders 41 rotate outside the second threaded rod 33, which makes the connection between the components of the lifting ring more flexible, and the structure is simple and easy to operate. When the components of the lifting ring are damaged after long-term use, it is easy to quickly maintain and replace each component individually, reducing the cost of use.

[0036] Considering that lifting rings are prone to damage from prolonged impacts and have a short service life, buffer pads 5 are fixedly connected to both the outer side of the rotating part 11 and the inner side of the rotating cylinder 41. When the lifting ring is subjected to impact loads, the buffer pads 5 can absorb and disperse the impact force, reduce the instantaneous stress on the connection parts, reduce the risk of disengagement, and extend the service life of the lifting ring.

[0037] In summary, the working principle of this solution is as follows:

[0038] First, the sliding rod 21 retracts into the second groove 14 due to the elastic force of the spring 23. At this time, the lifting ring is first threadedly connected to the external connector through the first threaded rod 12 to determine the installation position of the lifting ring and to initially lock it with the external connector. Then, the insert rod 24 is inserted into the first groove 13. The protrusion 25 at the bottom of the insert rod 24 squeezes the connecting plate 22 and the spring 23. At this time, the two sliding rods 21 slide outward inside the second groove 14 and engage with the external connector to perform a secondary connection and lock, increasing the force-bearing area of ​​the connection between the lifting ring and the external connector, effectively preventing the lifting ring from disengaging due to displacement in different directions during the force process. Then, the insert rod 24 is rotated, and the insert rod 24 is threadedly connected to the threaded groove 16 through the threaded teeth 26 to lock the position of the insert rod 24, ensuring a stable connection between the sliding rod 21 and the external connector. In addition, the upper end of one side of the insert rod 24 is symmetrically fixedly connected with a limit block 27. Perpendicular to the fixed direction of the protrusion 25, the direction of the limiting block 27 is determined to ensure stable contact between the protrusion 25 and the connecting plate 22, ensuring the squeezing effect of the protrusion 25 on the connecting plate 22, thereby ensuring the locking connection effect between the sliding rod 21 and the external connecting parts, forming a double lock, effectively preventing the lifting ring from disengaging due to displacement in different directions during the force process, and increasing the anti-disengagement effect of the lifting ring. The two mounting blocks 3 are rotatably mounted on the outside of the rotating part 11 through the fixing plate 31 and the fixing part 32. The second threaded rod 33 is threadedly connected to one side of the mounting block 3. The ring 4 rotates outside the second threaded rod 33 through the rotating cylinder 41. During use, the ring 4 can be rotated in multiple directions, increasing the flexibility of the ring 4 during use and meeting the needs of different drilling and lifting operations. When the lifting ring is subjected to impact load, the buffer pad 5 can absorb and disperse the impact force, reduce the instantaneous stress on the connection part, reduce the risk of disengagement, and extend the service life of the lifting ring.
