Description

Technical Field

[0001] The present invention belongs to the technical field of finger beam locking and standpipe discharge, and in particular relates to a finger beam locking structure. The present invention also relates to a locking method of the locking structure. Background Art

[0002] At present, in order to adapt to the automation and intelligence of oil drilling rigs, major equipment suppliers around the world have developed corresponding equipment. As the core equipment of oil drilling rigs, the discharge of standpipes is changed from manual discharge to automatic discharge. The end of the finger beam needs a finger beam lock to achieve automatic flipping. When it is necessary to discharge or use the standpipes, the finger beam lock is opened, and after the operation is completed, the finger beam lock is closed. It is one of the main mechanisms of the second-layer platform.

[0003] In order to meet this function, various types of finger beam lock flip mechanisms have emerged, such as cylinder-driven finger beam locks, motor or electric push rod-driven finger beam locks, and finger beam locks driven by elastic components. Various forms of finger beam locks have different problems. Pneumatic finger beam locks cannot adapt to low-temperature working environments, electric finger beam locks are expensive and have a high failure rate, and finger beam locks driven by elastic components are easily blocked by foreign objects. Summary of the invention

[0004] The purpose of the present invention is to provide a finger beam lock locking structure, which can achieve low temperature environment operation while reducing production costs and improving work efficiency.

[0005] Another object of the present invention is to provide a finger beam lock locking method.

[0006] The first technical solution adopted by the present invention is a finger beam lock locking structure, including a driving motor, which is connected to the base through a flange, and a groove is opened on the base along the axis of the vertical driving motor. A clamping plate is arranged in the groove, and the output end of the driving motor is connected to the clamping plate through the side wall of the base to control the clamping plate to rotate, thereby completing the locking and unlocking of the finger beam lock.

[0007] The first technical solution of the present invention is also characterized in that:

[0008] The driving motor includes an explosion-proof shell, a U-shaped support is fixedly connected to the bottom of the explosion-proof shell, the opening of the U-shaped support faces the top of the explosion-proof shell, and a rotating electromagnet is also arranged in the explosion-proof shell. The output end of one end of the rotating electromagnet passes through the explosion-proof shell and is connected to the card plate, and the other end passes through the U-shaped support and is connected to the induction plate. A detector for detecting the rotation angle of the rotating electromagnet is installed on the U-shaped support.

[0009] At least one pair of detectors is installed, and are respectively installed at the starting position and the ending position of the rotation of the rotary electromagnet.

[0010] The detector and the rotary electromagnet are connected to the host computer through wires, transmitting the rotation signal of the rotary electromagnet to the host computer for monitoring and sending an electrical signal to the rotary electromagnet.

[0011] The output end of the drive motor is connected with a rotating shaft through a coupling. The rotating shaft passes through the clamping plate and is movably connected to the base. There is an interference fit between the rotating shaft and the clamping plate.

[0012] Bearings are provided at the connection positions of the base relative to the rotating shaft. The rotating shaft is movably connected to the base through the bearings.

[0013] A end cover is connected to one side of the base relative to the rotating shaft position. The rotating shaft can be replaced by disassembling the end cover.

[0014] The second technical solution adopted by the present invention is the locking method of the finger beam lock. The host computer sends an electrical signal to the drive motor to start the drive motor. The drive motor drives the rotating shaft to perform a rotational movement. The clamping plate rotates synchronously under the action of the bearing. After the induction plate in the drive motor rotates to the specified position, the detector detects the signal and feeds back the in-place signal to the host computer to complete the locking or unlocking work.

[0015] The beneficial effect of the present invention is that the finger beam lock locking structure of the present invention uses a rotary electromagnet as the driving power source, is not affected by environmental factors, has high operating stability, can adapt to various working conditions, and at the same time forms a rotary angle in-place feedback structure through the induction plate and the detector. After being connected to the host computer through wires, it can realize the control of the rotary electromagnet and the acquisition of working condition information, and know immediately when a fault occurs.

[0020] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0021] Embodiment 1

[0022] As Figure 1As shown in the figure, the present invention relates to a locking structure of a finger beam lock, which includes a driving motor 1. The driving motor 1 is connected to a base 3 through a flange. A groove is formed in the base 3 along the axis perpendicular to the driving motor 1. A clamping plate 7 is arranged in the groove. The output end of the driving motor 1 passes through the side wall of the base 3 and is connected to the clamping plate 7, driving the clamping plate 7 to rotate, so as to complete the locking and unlocking of the finger beam lock.

[0023] Embodiment 2

[0024] As Figure 2 As shown in the figure, the present invention relates to a locking structure of a finger beam lock, which includes a driving motor 1. The driving motor 1 is connected to a base 3 through a flange. A groove is formed in the base 3 along the axis perpendicular to the driving motor 1. A clamping plate 7 is arranged in the groove. The output end of the driving motor 1 is connected to a rotating shaft 4 through a coupling 2. The rotating shaft 4 passes through the clamping plate 7 and is movably connected to the base 3. In order to ensure the transmission of the rotating force of the rotating shaft 4, an interference fit is provided between the rotating shaft 4 and the clamping plate 7.

[0025] Bearings 5 are arranged at the connection positions of the base 3 relative to the rotating shaft 4 to prevent the direct contact between the rotating shaft 4 and the base 3, which may cause damage to the rotating shaft during long-term use and significantly reduce the service life of the rotating shaft 4. Therefore, the rotating shaft 4 is movably connected to the base 3 through the bearings 5. On the one hand, the service life of the rotating shaft 4 is extended, and on the other hand, the loss of force during the rotation of the rotating shaft 4 is reduced. A end cover 6 is connected to one side of the base 3 relative to the rotating shaft 4. When the rotating shaft 4 needs to be replaced, the end cover 6 can be removed and then the coupling 2 can be loosened to replace the rotating shaft 4, which is very convenient and easy to operate without disassembling and assembling the entire base 3, improving the work efficiency.

[0026] Start the driving motor 1, drive the rotating shaft 4 to rotate through the driving motor 1. When the rotating shaft 4 rotates, it drives the clamping plate 7 to rotate synchronously, so as to control the clamping plate 7 to complete the locking and unlocking of the finger beam lock.

[0027] Embodiment 3

[0028] The locking structure of the finger beam lock of the present invention includes a driving motor 1. As Figure 3 shown in the figure, the driving motor 1 includes an explosion-proof housing 8. A U-shaped support 9 is fixedly connected to the bottom of the explosion-proof housing 8. The opening of the U-shaped support 9 faces the top of the explosion-proof housing 8. A rotary electromagnet 10 is also arranged in the explosion-proof housing 8. The rotary electromagnet 10 is divided into two parts: electromagnetic force and rotation. First, the electromagnetic force, that is, magnetic force. Under the action of the magnetic force, the position of the electromagnet will change over time, so as to drive the mechanical device. And rotation refers to the process of releasing the magnetic force, that is, restoring the position of the electromagnet to its original position, so as to achieve the purpose of rotation. The rotary electromagnet 10 can make the movement more accurate and reliable, so as to complete the operation work with higher efficiency.

[0029] One output end of the rotary electromagnet 10 passes through the explosion-proof housing 8 and is connected to the clamping plate 7, and the other end passes through the U-shaped support 9 and is connected with an induction plate 11. A detector 12 for detecting the rotation angle of the rotary electromagnet 10 is installed on the U-shaped support 9.

[0030] At least a pair of detectors 12 are installed, and are respectively installed at the starting and ending positions of the rotation of the rotary electromagnet 10. The induction plate 11 is made of a metal material. When the rotary electromagnet 10 is started, since the induction plate 11 is a metal conductor, an induced current will be formed inside it, and the detector 12 captures the induced current to complete the position signal transmission between the induction plate 11 and the detector 12.

[0031] The detector 12 and the rotary electromagnet 10 are connected to the upper computer through wires, transmit the rotation signal of the rotary electromagnet 10 to the upper computer for monitoring, and send an electrical signal to the rotary electromagnet 10 according to the detected position to control the movement of the rotary electromagnet 10.

[0032] The driving motor 1 is connected to the base 3 through a flange. A groove is formed in the base 3 along the axial direction perpendicular to the driving motor 1. A clamping plate 7 is arranged in the groove. The output end of the driving motor 1 is connected with a rotating shaft 4 through a coupling 2. The rotating shaft 4 passes through the clamping plate 7 and is movably connected with the base 3. An interference fit is provided between the rotating shaft 4 and the clamping plate 7.

[0033] Bearings 5 are arranged at the connection positions of the base 3 relative to the rotating shaft 4. The rotating shaft 4 is movably connected with the base 3 through the bearings 5. An end cover 6 is connected to one side of the base 3 relative to the position of the rotating shaft 4, and the rotating shaft 4 can be replaced by removing the end cover 6.

[0034] That is, when the driving motor 1 is started, the rotating shaft 4 is driven by the driving motor 1 to perform a rotational motion, so as to control the clamping plate 7 to perform a rotational motion, and complete the locking and unlocking of the finger beam lock.

[0035] In the finger beam lock locking method of the present invention, when in use, the finger beam lock locking structure is installed at the finger beam on the second floor platform. According to the on-site operation requirements, a locking or unlocking operation is performed. The upper computer sends an electrical signal to the driving motor 1. After the driving motor receives the electrical signal, the rotary electromagnet 10 makes a corresponding rotational motion. The rotating shaft 4 connected to the rotary electromagnet 10 is driven by the coupling 2 to perform a rotational motion, and at the same time drives the clamping plate 7 to rotate; at the same time, the induction plate 11 connected to the rotary electromagnet 10 rotates synchronously with the rotary electromagnet 10. When the rotary electromagnet 10 rotates to the locking position or the unlocking position, the detector 12 receives the position information of the induction plate 11, and thus transmits the signal that the rotary electromagnet 10 rotates in place to the upper computer, completing the locking or unlocking work of the locking structure of the present invention.

[0036] If, after sending a rotation signal to the rotary electromagnet 10, the in-place signal feedback from the detector 12 is not received for a long time, it indicates that the rotary electromagnet 10 has not fully carried out the locking or unlocking operation. It is necessary to stop the working equipment and arrange for staff to conduct an inspection to avoid further equipment damage or safety accidents.
