Description

Technical Field

[0001] This utility model relates to the field of oil drilling equipment technology, and in particular to an electric drive finger beam lock mechanism. Background Technology

[0002] In oil drilling and workover operations, to prevent drill pipes within the second-level drilling rig from swaying or detaching from the rig due to external factors, thus causing safety accidents, a common approach is to add multiple rig locks to restrict the drill pipe's movement. There are two common types of rig locks: non-powered rig locks, which require manual operation by the derrickman; and powered rig locks, which typically use a cylinder as the drive mechanism. These rig locks are embedded within the rig, making disassembly and assembly difficult and hindering on-site maintenance. Furthermore, their larger size requires more installation space, making them unsuitable for upgrading older drilling rigs. Additionally, the locking tongues of the rig locks are easily subjected to impact forces from the tubing, making the equipment prone to loosening and damage. Utility Model Content

[0003] This utility model discloses an electrically driven finger beam lock mechanism, which aims to solve the technical problem of difficult disassembly and assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrically driven finger beam lock mechanism includes a two-layer platform finger beam, characterized in that a base is welded to the upper surface of the two-layer platform finger beam, a finger beam frame is installed on the upper surface of the base by bolts, a drive motor is fixedly installed at one end of the finger beam frame, and a pin tongue is connected to the output end of the drive motor through a reducer.

[0006] The pin includes a first tongue body, one end of which has an adjustment groove. A second tongue body is installed inside the adjustment groove. Several bolt holes are formed on the surfaces of the first and second tongue bodies. Bolts are connected through the bolt holes. The upper and lower surfaces of the first tongue body have recessed grooves. When the pin is subjected to vertical pressure, the spacing between the adjustment grooves can be reduced, and the pin can deform around the recessed groove.

[0007] In a preferred embodiment, bearings are installed on both sides of the finger beam frame, the outer ring of the bearing is limited by end caps I and II on both sides of the finger beam frame by bolts, and the inner ring of the bearing is installed on the rotating shaft of the drive motor.

[0008] In a preferred embodiment, the inner ring of the bearing is limited by a bushing and a retaining ring mounted on the rotating shaft.

[0009] In a preferred embodiment, the end cap II is bolted to a protective cover for protecting the drive motor, and a sealing cover is installed at the rear end of the protective cover.

[0010] In a preferred embodiment, a recessed groove is provided around the bolt hole to accommodate the bolt.

[0011] In a preferred embodiment, an oil cup is provided at one end of the finger beam frame.

[0012] As can be seen from the above, the electric drive finger beam lock mechanism provided by this utility model has the following technical effects.

[0013] Firstly, the finger beam lock provided by this utility model places the driving element on the outside of the finger beam, and has a small overall size, light weight, and low installation space requirements. It is not only suitable for various models of new drilling rigs, but also for various structures of old drilling rigs and well workover rigs, with a wide range of applications.

[0014] Secondly, the pin tongue adopts a combined adjustable structure, thereby adjusting the working range of the pin tongue. In addition, when the pin tongue is subjected to vertical pressure, it can cause the spacing between the adjustment grooves to decrease, and at the same time, it can deform around the position of the recessed groove, thereby buffering the external force and preventing the instantaneous impact force from damaging the drive motor.

[0027] 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.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-11 An electrically driven finger beam lock mechanism includes a two-tiered finger beam 6, with a base 1 welded to the upper surface of the two-tiered finger beam 6. A finger beam frame 2 is bolted to the upper surface of the base 1. A drive motor 15 is fixedly mounted at one end of the finger beam frame 2. The output end of the drive motor 15 is connected to a pin tongue 3 via a reducer 14. Bearings 11 are mounted on both sides of the finger beam frame 2. The outer ring of the bearing 11 is limited by end caps I7 and II8 bolted to both sides of the finger beam frame 2. The inner ring of the bearing 11 is mounted on the rotating shaft 12 of the drive motor 15. The inner ring of the bearing 11 is limited by a bushing 13 and a retaining spring 10 mounted on the rotating shaft 12.

[0030] In this embodiment, the pin tongue 3 of this application is installed with the finger beam frame 2, and the finger beam frame 2 is installed with the base 1. The base 1 is then welded and fixed to the second-layer platform finger beam 6. Meanwhile, the opening and closing of the pin tongue 3 is accomplished by the drive motor 15, which makes the overall layout compact, the installation space small, and the installation method simple. It is not only suitable for various new drilling and repair machines, but also for the upgrading and transformation of various old drilling machines, and has a wide range of applications.

[0031] Specifically, the beam frame 2 has a symmetrical structure with through holes and threaded holes of the same position and size on both sides, and an internal recessed groove with two open sides. The symmetrical structure of the beam frame 2 makes installation simple, provides good interchangeability, and reduces the likelihood of errors. The two sides of the internal recessed groove serve as limiting surfaces for the opening and closing movement of the pin tongue 3, preventing excessive rotation.

[0032] Among them, the end cover II8 is fixed with a protective cover 4 by bolts to protect the drive motor 15, and a sealing cover 5 is installed at the rear end of the protective cover 4.

[0033] Furthermore, such as Figure 5 and Figure 6 The base 1 shown is a boss structure, and the beam frame 2 is a groove structure. The two are connected together. This structure can not only improve the positioning accuracy, but also improve the stress condition. When the pin tongue 3 is impacted by the drill rod, the connecting bolt no longer bears the shear force, which further ensures the reliability of the bolt connection.

[0034] Furthermore, such as Figure 4 and Figure 7 As shown, there are lubricating oil channels on the rotating shaft 12, and a lubricating oil cup 9 is installed on one side of the rotating shaft 12; the lubricating oil channels facilitate on-site maintenance operations, ensure normal operation of the equipment, reduce wear, and extend service life.

[0035] Figure 4 As shown, the sealing cover 5 has a gland connection hole for sealing the cable connection of the drive motor 15, thereby forming a sealed space inside the cover 4, which effectively protects the reducer 14 and the drive motor 15. The cover 4 forms a sealed space to isolate the actuator from the working environment, protecting it from dust, water vapor and salt spray corrosion.

[0036] In another implementation, such as Figures 9-11 The pin tongue 3 includes a first tongue body 301, an adjustment groove 302 is provided at one end of the first tongue body 301, a second tongue body 303 is installed inside the adjustment groove 302, a plurality of bolt holes 304 are provided on the surfaces of the first tongue body 301 and the second tongue body 303, and bolts 305 are connected through the bolt holes 304. The upper and lower surfaces of the first tongue body 301 are provided with recessed grooves 307.

[0037] In this embodiment, the pin tongue 3 adopts a combined adjustable structure. The pin tongue 3 can be inserted into the first tongue 301 via the second tongue 303 and fixed by the bolt 305, thereby adjusting the working range of the pin tongue 3. It also allows the bolt holes 304 at different positions to be overlapped and fixed, enabling fine-tuning. Furthermore, when the pin tongue 3 is subjected to vertical pressure, such as... Figure 11As shown, it can cause the spacing between the adjustment grooves 302 to become smaller, and at the same time, it can deform around the position of the recessed groove 307, thereby buffering external forces and preventing instantaneous impact forces from damaging the drive motor 15. The first tongue 301 and the second tongue 303 are tough as a whole and can recover after deformation.

[0038] Working principle: When using the finger beam lock provided by this utility model for pipe-retrieving operations, such as Figure 9 Operate the drive motor 15 to open the pin 3 on the designated finger beam lock and keep the finger beam lock in the open state. After a single pipe column is removed, operate the drive motor 15 to rotate the pin 3 on the finger beam lock and close the finger beam lock. Repeat this process to complete the removal of all pipe columns.

[0039] During the pipe string discharge operation, operate the drive motor 15 to open the pin tongue 3 on the designated finger beam lock, ensuring that the finger beam lock is in the open state, and then insert the pipe string. After the discharge of a single pipe string is completed, operate the drive motor 15 to rotate the pin tongue 3 on the finger beam lock, thereby closing the finger beam lock. In this way, the discharge operation of all pipe strings is completed.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
