Description

Technical Field

[0001] This invention relates to the field of heavy lifting equipment automation technology, specifically to an adaptive remote control opening and closing tool for heavy lifting hooks and its installation method. Background Technology

[0002] With the continuous development of industrial automation technology, heavy lifting equipment is being used more and more widely in various industries. During the disassembly and assembly of derricks, the derrick is often at a high altitude, and the opening and closing of the heavy hook locking tongue is one of the necessary actions to be performed, whether it is the assembly or disassembly of the derrick.

[0003] To achieve unmanned and automated derrick assembly work, aiming to use robots to replace manual labor in high-altitude operations, the inventors' team conducted extensive research and development. During this process, they discovered that existing heavy-duty hook locking tongue operations still rely on manual methods, resulting in low operational safety, low work efficiency, and insufficient remote control capabilities. In high-altitude or complex environments, manual operation of the locking tongue easily poses safety hazards, and frequent operation significantly reduces work efficiency. Furthermore, most existing equipment lacks remote control capabilities, requiring operators to be close to the hook, which cannot meet the demands of complex and changing working environments. Summary of the Invention

[0004] This invention provides an adaptive remote control opening and closing tool for heavy-duty hook locking tongues and its installation method, in order to solve the problems of manual operation of heavy-duty hook locking tongues in the prior art, which results in low operational safety and efficiency. The invention aims to improve the automation level of heavy-duty hook operations, increase operational efficiency and accuracy, and reduce the risks of high-altitude operations.

[0005] This invention is achieved through the following technical solution:

[0006] An adaptive remote control opening and closing heavy-duty hook locking tongue tool includes a main body mechanism for connecting to the hook and a toggle actuator connected to the main body mechanism;

[0007] The main structure includes a support plate, a V-groove at the bottom of the support plate, a positioning rope connected to the support plate, and a hook neck clamp; the positioning rope and the hook neck clamp are located at opposite ends of the support plate; the positioning rope is used to wrap around the hook arm; the hook neck clamp is hinged to the support plate.

[0008] The actuation mechanism includes a servo motor, a servo arm connected to the output end of the servo motor, and a lever connected to the servo arm.

[0009] To address the problems of low safety and efficiency in existing technologies that require manual operation of the opening and closing of heavy-duty hook locking tongues, this invention proposes an adaptive remote-controlled opening and closing tool for heavy-duty hook locking tongues. The main body mechanism connects and installs the tool to the hook body, while the actuating mechanism performs the opening action on the hook locking tongue. Specifically, the main body mechanism includes a support plate, a V-groove, a hook neck clamp, and a positioning rope, wherein:

[0010] As the name suggests, the hook neck clamp is a clamp used to hold the neck of a hook. The support plate and the hook neck clamp are hinged together, allowing the V-groove to adaptively contact different hook backs, significantly increasing the adaptability of this application to different heavy-duty hooks and expanding its application range. Furthermore, the self-centering function of the V-groove can be used to achieve centering contact between the support plate and the hook back. The positioning rope passes around the hook arm during use, ensuring relative stability between the support plate and the hook arm. Simultaneously, after tensioning the positioning rope, it ensures the stability of the fit between the hook back and the V-groove, preventing the hook back from detaching from the V-groove. Moreover, the material of the positioning rope in this application is not specifically limited.

[0011] In the actuation mechanism, the servo motor drives the servo arm to swing, which in turn drives the lever to move. The lever applies a thrust to the hook latch, thereby opening the hook latch. When it is necessary to close the hook latch, the servo motor is simply used to swing the servo arm back to its original position.

[0012] This application overcomes the problem of requiring manual operation of the locking tongue of heavy-duty hooks in existing technologies. It can be combined with existing automation technologies to achieve automatic operation or remote control by personnel, significantly improving the automation level, efficiency, and accuracy of heavy-duty hook operations. In frequent lifting conditions (such as derrick assembly and disassembly), it can significantly reduce the workload of operators, improve overall work efficiency, reduce the risks of high-altitude operations, improve operational safety, and reduce the error rate during lifting operations, thus improving operational accuracy. This application has the ability to cope with different working environments, such as being compatible with heavy-duty hooks of different types and curved structures, exhibiting strong adaptability and expanding the scope of application for automated hook operations. This application does not require changes to the existing hook structure; it can be installed on the existing hook structure, exhibiting strong compatibility and economy.

[0013] This application can be used in the derrick assembly and disassembly process in oil and gas drilling projects, and can also be used in other high-altitude operations that require the use of heavy-duty hooks.

[0014] Furthermore, the hook neck clamp includes a matching hook neck front clamp and a hook neck rear clamp; the hook neck rear clamp is hinged to the support plate, and the hook neck front clamp and the hook neck rear clamp are detachably connected.

[0015] This solution uses a front hook neck clamp and a rear hook neck clamp to form a clamping structure similar to a hoop, thereby achieving a stable connection between the present invention and the hook neck. The rear hook neck clamp is hinged to the support plate; therefore, during installation, the front hook neck clamp is first removed, then the front and rear hook neck clamps are respectively placed on both sides of the hook neck, and finally the front hook neck clamp is connected to the rear hook neck clamp. In this solution, the connection between the front and rear hook neck clamps can be achieved through any existing detachable method, provided that it does not affect the normal clamping of the hook neck.

[0016] Furthermore, it also includes a tensioning mechanism for tensioning the positioning rope;

[0017] The tensioning mechanism includes a locking seat fixedly connected to the pallet, a guide connected to the locking seat and / or the pallet, a locking moving block slidably engaged with the guide, and a driving assembly for driving the locking moving block to slide along the guide; the sliding direction of the locking moving block is perpendicular to the surface of the pallet; both ends of the positioning rope are fixedly connected to the locking moving block.

[0018] To ensure stable installation of hooks of different sizes and models, a tensioning mechanism is specifically designed. However, traditional tensioning mechanisms typically utilize winding equipment. Given the relatively harsh working conditions encountered in this application, the positioning rope must be made of a high-strength material, making winding and tensioning difficult. Therefore, a dedicated tensioning mechanism is employed. Specifically, in use, the tensioning mechanism of this solution involves a drive assembly that propels a locking block along a guide. When the locking block moves away from the support plate, the positioning rope is tensioned; when the locking block approaches the support plate, the positioning rope is relaxed. Thus, this solution allows for flexible adjustment of the positioning rope tension according to specific working conditions, adapting to hooks of different sizes and models. This tensioning method eliminates the need for winding and tensioning, making it more suitable for high-strength, high-hardness positioning ropes.

[0019] Furthermore, the drive assembly includes a tensioning screw that is threadedly engaged with the set seat and a clamping piece that is fixedly connected to the set moving block; one end of the tensioning screw is rotatably engaged with the clamping piece; the axis of the tensioning screw is parallel to the sliding direction of the set moving block.

[0020] In this solution, simply rotating the tensioning screw will drive the locking moving block to make linear motion, thereby tightening or loosening the positioning rope. The drive component of this structure is simple and does not require an additional power source. It can be installed and positioned by simple manual operation.

[0021] Furthermore, the actuating mechanism also includes a servo mount for mounting the servo; the servo mount is connected to the main body via a connecting rod. This solution uses a connecting rod to connect the actuating mechanism to the main body, while also providing support and stability to the actuating mechanism, thereby ensuring that the actuating mechanism can be located in the vicinity of the hook locking tongue.

[0022] Furthermore, the main body mechanism also includes a friction disc clamp and a friction disc seat that are matched with each other. The friction disc seat and the friction disc clamp are rotatably engaged and in contact with each other. The end of the connecting rod away from the servo mount is connected to the friction disc seat.

[0023] In this design, one end of the connecting rod is connected to the friction disc base. Rotating the friction disc base adjusts its orientation, which in turn drives the connecting rod to rotate synchronously. This adjusts the angle of the connecting rod and the position angle of the actuating mechanism, thus better adapting to different models, sizes, or types of hooks. Furthermore, the friction between the friction disc clamp and the friction disc base must be sufficient to ensure that the friction disc base does not rotate under normal conditions when the clamp and the base are in close contact. Of course, if it is necessary to adjust the angle and orientation of the friction disc base, the clamp can be temporarily released from its constraint. The friction engagement between the clamp and the base can be achieved using any existing technology; no specific limitations are imposed here.

[0024] Furthermore, the main body also includes a support seat that slides on the tray and a support seat fastening screw for temporarily positioning the support seat. The sliding direction of the support seat is perpendicular to the axis of the V-groove. The friction disc clamp is detachably connected to the support seat.

[0025] In this design, the friction disc clamp is connected to the support base. When the support base slides, the friction disc clamp and the friction disc seat that mates with it also slide synchronously, thereby moving one end of the connecting rod. Since the sliding direction of the support base is perpendicular to the axis of the V-groove, meaning the support base slides along the lateral direction of the hook, it can drive one end of the connecting rod to move laterally, thus adjusting the lateral position of the actuating mechanism. This is more suitable for use with heavy-duty hooks of different models and sizes. Once the support base has moved to the appropriate position, it is secured with the fastening screws to prevent further free sliding.

[0026] Furthermore, an actuator-end connecting rod clamp is provided on the servo mount, and a main body-end connecting rod clamp is provided on the friction disc mount;

[0027] The two ends of the connecting rod pass through the actuator-end connecting rod clamp and the main body-end connecting rod clamp, respectively.

[0028] The connecting rod is clamped from both sides by the actuator-end connecting rod clamp and the main body-end connecting rod clamp, respectively, to ensure its stability during operation. Both the actuator-end and main body-end connecting rod clamps are through-hole type clamps, allowing adjustment of the clamping positions to control the length and distance of the extended connecting rod, thereby adjusting the forward and backward position of the actuator to achieve optimal actuation. This design is more suitable for use with heavy-duty hooks of different models and sizes.

[0029] Furthermore, the main structure also includes an electrical box located on the tray. This solution, through the electrical box, enables human-machine interaction and remote control, and the electrical box contains built-in control elements for controlling the operation of the servo motor.

[0030] An installation method for an adaptive remote-controlled opening and closing heavy-duty hook locking tongue tool, used for installing the adaptive remote-controlled opening and closing heavy-duty hook locking tongue tool of this application, includes the following steps:

[0031] S1. Install the hook neck clamp on the hook neck; adjust the position of the hook neck clamp so that the V-groove is facing the back of the hook, so that the hook neck clamp clamps the hook neck.

[0032] S2. Press down the support plate so that the V-groove is inverted onto the back of the hook;

[0033] S3. Wrap the positioning rope around the hook arm at least one turn and tension the positioning rope.

[0034] S4. Install the actuating mechanism so that the lever is located outside the hook latch and directly opposite the hook latch.

[0035] This solution allows for the installation and testing of the tool described in this application to be completed on the ground, and then used to control the automatic opening and closing of the hook locking tongue.

[0036] Compared with the prior art, the present invention has at least the following advantages and beneficial effects:
