Description

Technical Field

[0001] This invention relates to the field of drilling equipment maintenance tools, and in particular to a compatible top drive electrical interconnection device. Background Technology

[0002] The top drive electrical interconnection system is an electrical connection system that enables reliable transmission of power and control signals between the electrical control system and the top drive body under high-frequency vibration, impact, tension, torsion, and upstream and downstream motion conditions above the derrick. After a failure of the top drive electrical interconnection system, repair and commissioning are required. However, in existing technologies, because each top drive electrical interconnection system is a customized product, with different structures, processes, and signal types used by different top drive brands, the electrical control room, electrical interconnection system, and driller's console must be returned to the factory simultaneously for top drive body inspection, repair, and factory commissioning. This results in high transportation and repair costs and low repair efficiency. With technological advancements, the top drive electrical control system and electrical interconnection system are now integrated into the drilling rig control system, making it impossible to return them with the top drive. This prevents factory commissioning after return repairs, compromising repair quality. Therefore, to address these shortcomings, a compatible top drive electrical interconnection device is proposed. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a compatible top drive electrical interconnection device, which solves the problem that the incompatibility between top drives of different brands and manufacturers necessitates the return of all supporting equipment to the factory for top drive maintenance and commissioning. It also solves the problem that the top drive electrical control system and electrical interconnection system are both integrated into the drilling rig control system, making it impossible to return the top drive to the factory for maintenance and commissioning after the return trip.

[0004] (II) Technical Solution To address the above problems, the present invention provides a compatible top drive electrical interconnection device, comprising: The system comprises a top drive body, a photoelectric signal switching device, and a host testing system. The photoelectric signal switching device includes an auxiliary power switching module and a control signal switching module. The input of the auxiliary power switching module is connected to the output of the top drive body, and the output is connected to the input of the host testing system, converting the power signal emitted by the top drive body into a signal format readable by the host testing system. The input of the control signal switching module is connected to the output of the host testing system, and the output is connected to the input of the top drive body, converting the control signal emitted by the host testing system into a signal format corresponding to the top drive body. Adjustable retractable connectors are provided at the connection points between the auxiliary power switching module, the control signal switching module, and the top drive body. The retractable connector includes a socket housing and a retractable ring, which is elastic. A core is provided on the connectors at the output and input ends of the top drive body. The core is inserted into the retractable ring and the socket housing, and the retractable ring clamps the core under its own elasticity.

[0005] Preferably, the photoelectric signal switching device is equipped with a monitoring module, which is connected to the auxiliary power switching module and the control signal switching module. The monitoring module reads the signals emitted by the top drive body and sends the signal conversion program to the auxiliary power switching module and the control signal switching module.

[0006] Preferably, the monitoring module marks the signals and signal conversion programs sent by the top drive body, and after reading the signals from the top drive body, sends the signal conversion programs with the same markings to the photoelectric signal switching device.

[0007] Preferably, the output end and input end of the top drive body are each provided with an explosion-proof junction box, and the retractable connector is connected to the explosion-proof junction box.

[0008] Preferably, the marked information includes the marked top drive body signal and the marked signal conversion program.

[0009] Preferably, the tagged information is stored in the monitoring module of the photoelectric signal switching device. The monitoring module compares the signal sent by the top drive body with the tagged information and selects the signal conversion program with the same tagged information to send to the photoelectric signal conversion device.

[0010] Preferably, the retractable connector further includes an elastic base, which is fixed to the socket housing and arranged concentrically with the socket housing; the retractable ring is fixed inside the elastic base.

[0011] Preferably, the inner wall edge of the contraction ring facing the top drive body has an inward chamfer structure.

[0012] (III) Beneficial Effects The compatible top drive electrical interconnection device and method provided by this invention connects to the top drive body via a retractable connector and clamps the core on the top drive body side via a retractable ring, enabling stable connection with connectors of different sizes on the top drive body.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "top", and "bottom" are based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this invention and to simplify the description. It is not intended to indicate or imply that the component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0017] like Figure 1-2As shown, this invention provides a compatible top drive electrical interconnection device, specifically including: a top drive body 1, a photoelectric signal switching device 4, and a host testing system 6. The top drive body 1 is the target for maintenance and factory testing. The host testing system 6 receives the working signals sent by the top drive body 1 and sends control signals to the top drive body 1 according to its working status. It compares the working signals fed back by the top drive body 1 with the control signals sent to the top drive body 1 to perform factory testing on the top drive body 1. Typically, the host testing system 6 is a control system used within the factory and does not change with the model or manufacturer of the top drive body 1. However, different manufacturers and models of top drive bodies 1 use different processing technologies and signal encoding methods. Therefore, the host testing system 6 alone cannot connect to the top drive body 1 and cannot read the signals sent by the top drive body 1. The photoelectric signal switching device 4 is installed between the top drive body 1 and the main test system 6, connecting the top drive body 1 and the main test system 6 and performing signal conversion between them, so that the main test system 6 can debug the top drive body 1 without using facilities such as the electrical control room, electrical interconnection system and driller's operating table that are matched with the top drive body 1.

[0018] The photoelectric signal switching device 4 includes an auxiliary power switching module and a control signal switching module. The input of the auxiliary power switching module is connected to the output of the top drive body 1, and its output is connected to the input of the host testing system 6, converting the power signal emitted by the top drive body 1 into a signal format readable by the host testing system 6. The input of the control signal switching module is connected to the output of the host testing system 6, and its output is connected to the input of the top drive body 1, converting the control signal emitted by the host testing system 6 into a signal format corresponding to the top drive body 1. Through the auxiliary power switching module and the control signal switching module, the photoelectric signal switching device 4 can perform signal conversion between the top drive body 1 and the host testing system 6, enabling the host testing system 6 to read the information within the working signal sent by the top drive body 1, and simultaneously enabling the control signal sent by the host testing system 6 to be received, read, and used to send a response signal through the control terminal according to the content of the control signal. The photoelectric signal switching device 4 contains multiple signal conversion programs. After connecting to the top drive body 1, it selects the corresponding signal conversion program according to the signal type emitted by the top drive body 1 to convert the signal emitted by the top drive body 1 into a signal recognizable by the host testing system 6. In actual operation, the signal conversion program stored in the photoelectric signal switching device 4 can be added at any time. Before operation, the signal conversion program corresponding to the model of the top drive body 1 is input into the photoelectric signal switching device 4. The photoelectric signal switching device 4 can convert the signal of the top drive body 1 model that has been entered with the signal conversion program to that of the host test system 6.

[0019] The photoelectric signal switching device 4 is equipped with a monitoring module 5, which is connected to the auxiliary power switching module and the control signal switching module. The monitoring module 5 reads the signals emitted by the top drive body 1 and sends the signal conversion program to the auxiliary power switching module and the control signal switching module. During the operation of the photoelectric signal switching device 4, the monitoring module 5 reads the signals emitted by the top drive body 1 in real time, selects the corresponding signal conversion program according to the signal type of the top drive body 1, and sends the program to the auxiliary power switching module and the control signal switching module. This enables the photoelectric signal switching device 4 to realize signal transmission between the top drive body 1 and the host test system 6. The host test system 6 can correctly read the signal content emitted by the top drive body 1 and also control the working status of the top drive body 1 by sending control signals. In general, to ensure the normal operation of the monitoring module 5, the signals emitted by the top drive body 1, which are commonly used in the field, and the conversion program between the signals and the signals that the host test system 6 can receive and read are input into the monitoring module 5 before operation. After the monitoring module 5 reads the signal of the top drive body 1, it will determine its model and manufacturer through the signal of the top drive body 1, and select the corresponding signal conversion program according to the pre-stored information and send it to the photoelectric signal switching device 4.

[0020] It should be noted that the monitoring module 5 marks the signals and signal conversion programs sent by the top drive unit 1. After reading the signals from the top drive unit 1, it sends the signal conversion programs with the same markings to the photoelectric signal switching device 4. When inputting the top drive unit 1 and the signal conversion programs, the top drive unit 1 and the photoelectric signal switching device 4 are first connected. At this time, the photoelectric signal switching device 4 receives the signals from the top drive unit 1 and simultaneously inputs the signal conversion programs between this model of top drive unit 1 and the host test system 6 used into the monitoring module 5. The monitoring module 5 marks the signals from the top drive unit 1 and the input signal conversion programs with the same markings. This process is repeated until the data of all models of top drive units 1 used is entered, and the marking information used for different models of top drive units 1 is different. After data entry is completed, during the inspection, maintenance, and factory testing of the top drive unit 1, the photoelectric signal switching device 4 is connected between the top drive unit 1 and the main testing system 6. The output signal of the top drive unit 1 is sent to the photoelectric signal switching device 4. The monitoring module 5 compares the received signal with the entered data, identifies the previously marked information, and sends the signal conversion program with the same mark to the photoelectric signal switching device 4. The auxiliary power switching module and the control signal switching module perform signal conversion between the top drive unit 1 and the main testing system 6 according to the received signal conversion program. Through the above device, the main testing system 6 can control and debug the top drive unit 1 without using the matching top drive electronic control system and electrical interconnection system, and without having to return the top drive unit 1 and its supporting equipment to the factory for maintenance, reducing transportation and maintenance costs and improving the efficiency of the top drive unit 1 maintenance work.

[0021] Generally, the marked information includes the marked signal of the top drive body 1 and the marked signal conversion program. Storing the signal emitted by the top drive body 1 and the signal conversion program separately and dividing them into separate datasets ensures that there is exactly one record for each mark in the same dataset, reducing the possibility of failure of the photoelectric signal conversion device 4.

[0022] The tagged information is stored in the monitoring module 5 of the photoelectric signal switching device 4. The monitoring module 5 compares the signal sent by the top drive body 1 with the tagged information and selects a signal conversion program with the same tagged information to send to the photoelectric signal conversion device 4. After reading the signal from the top drive body 1, the monitoring module 5 first compares it with the dataset corresponding to the signal from the top drive body 1 to obtain the correct tagged information. Then, it compares the tagged information with the dataset corresponding to the signal conversion program to obtain a signal conversion program with the same tagged information.

[0023] like Figure 1-2As shown, the auxiliary power switching module and the control signal switching module are connected to the top drive body 1 by a retractable connector 3. One end of the retractable connector 3 is connected to the photoelectric signal switching device 4 via a wire, and the other end is a connector-shaped part with adjustable size and elasticity. When connected to the top drive body 1, the size of the connection point varies depending on the signal and manufacturer of the top drive body 1. In this case, the size of the retractable connector 3 can be adjusted to correspond to the size of the connector point of the top drive body 1, so that it can be connected to the top drive body 1 of various signals without the need for other tools, ensuring stable signal transmission.

[0024] The retractable connector 3 includes a socket housing 301 and a retractable ring 304, the retractable ring 304 being elastic. A core 303 is provided on the connectors at the output and input ends of the top drive body 1. The core 303 is inserted into the retractable ring 304 and the socket housing 301, and the retractable ring 304 clamps the core 303 under its own elasticity. The socket housing 301 serves as the main body of the retractable connector 3, and its tail is connected to a wire, which in turn connects to the photoelectric signal switching device 4. When connecting the retractable connector 3 to the top drive body 1, the connector at the output or input end of the top drive body 1 needs to be inserted into the retractable connector 3. The core 303 is located inside the plug on the top drive body 1 side. After the core 303 is connected to the wire, it can connect the wire to the top drive body 1 to form a signal path. The retraction ring 304 is usually made of a material with good elasticity, such as rubber. When the core 303 is inserted into the retraction connector 3 and connected to the photoelectric signal switching device 4, the core 303 passes through the retraction ring 304 and enters the socket housing 301 and contacts the wire at the tail of the socket housing 301 to form a signal path. At this time, the retraction ring 304 will retract inward under its own elasticity and clamp the core 303, thereby fixing the position of the core 303 and fixing the retraction connector 3 on the top drive body 1.

[0025] In order to reduce the difficulty of connecting the core 303 to the retractable connector 3, the retractable ring 304 has an inward chamfer on the edge of the inner wall of the end that is disconnected from the core 303 inside the socket housing 301. When the core 303 is inserted into the retractable ring 304, the chamfer structure will guide the direction of the core 303 to the center direction of the elastic base 302 and the socket housing 301, so as to facilitate the contact between the core 303 and the wires inside the socket housing 301.

[0026] It should be noted that the retractable connector 3 also includes a flexible base 302, which is fixed to the socket housing 301 and arranged concentrically with it; the retraction ring 304 is fixed inside the flexible base 302. The flexible base 302 is used to limit and protect the retraction ring 304. Although the connectors of the top drive body 1 have different models, the actual dimensions of the connectors of various models of the top drive body 1 are not significantly different. The size of the flexible base 302 matches the largest connector size of the top drive body 1 model. When the retractable connector 3 is connected to the connector of the top drive body 1, the core 303 passes through the flexible base 302 and the retraction ring 304 and is inserted into the socket housing 301 to contact the wires and achieve connection with the photoelectric signal switching device 4. As the connector size of the top drive body 1 increases, the size of the core 303 also increases. After being inserted into the shrink ring 304, the elastic base 302 fixes the maximum diameter that the shrink ring 304 can reach, preventing the shrink ring 304 from deforming beyond its elastic limit after being inserted into the core 303. Simultaneously, as the shrink ring 304 expands outward, it contacts the inner wall of the elastic base 302 and clamps the shrink ring 304 with the core 303, thereby increasing the friction between the shrink ring 304 and the core 303 and improving the stability of the connection. During operation and storage, the elastic base 302 prevents external dust or corrosive liquids from contacting the shrink ring 304, avoiding corrosion and damage during operation and extending the service life of the shrink ring 304.

[0027] The compatible top drive electrical interconnection device provided by this invention can realize the electrical connection of the returned top drive body, and can realize the functional testing of the top drive body without returning the original factory electrical control system. The specific operation process of the device is as follows: Step 1: After assembling the device according to its structure, connect the photoelectric signal conversion device to the top drive body, and send control signals to the photoelectric signal conversion device through the top drive body.

[0028] Step 2: Connect the photoelectric signal conversion device to the control panel, and input the signal conversion program corresponding to the top drive body signal through the control panel. Then, attach the same marking information to the top drive body signal and the signal conversion program and save it.

[0029] Step 3: Replace the top drive unit with different signals, and repeat Step 1 and Step 2 until the information of all commonly used top drive unit models is entered and marked.

[0030] Step 4: Connect the photoelectric signal conversion device between the top drive body and the host test system to perform a top drive body operation test. At this time, the top drive body sends control signals to the photoelectric signal conversion device. The monitoring module inside the photoelectric signal conversion device compares the received signals with the marked information and selects the corresponding signal conversion program. The photoelectric signal conversion program then converts the signals sent by the top drive body into signals that the host test system can read.

[0031] Step 5: The host test system sends the debugging signal to the photoelectric signal conversion device, which converts the signal into a signal that the top drive body can read according to the signal conversion program selected in Step 3, and then sends it to the top drive body.

[0032] Step Six: The top drive unit takes action based on the received signal and sends a control signal from the output terminal, repeating Step Four. After the control signal enters the host test system, it is compared with the information previously sent by the host test system. If the two information contents match, the top drive unit is working normally; otherwise, it indicates that the top drive unit's performance needs to be re-maintained.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
