Description

Technical Field

[0002] The invention relates to the technical field of heavy lifting equipment automation, and in particular to an adaptive remote control heavy hook lock tongue opening and closing tool and an installation method thereof. Background Art

[0004] With the continuous development of industrial automation technology, heavy lifting equipment is increasingly used in various industries. During the process of derrick disassembly and assembly, the derrick is often at high altitude. Whether assembling or disassembling the derrick, opening and closing the heavy hook lock is one of the necessary operations.

[0005] To achieve unmanned and automated derrick assembly, and to replace manual labor with robots for high-altitude operations, the inventors' team conducted extensive research and development. During this process, they discovered that existing heavy-duty hook locks still rely on manual operation, resulting in low safety, low efficiency, and insufficient remote control capabilities. Manually operating the lock at high altitudes or in complex environments can easily pose safety risks, and frequent operation significantly reduces work efficiency. Furthermore, most existing equipment is incapable of remote control, requiring operators to operate close to the hook, which is unsuitable for complex and changing work environments. Summary of the Invention

[0007] The present invention provides an adaptive remote control opening and closing heavy hook lock tongue tool and an installation method thereof, so as to solve the problems in the prior art of requiring manual operation to open and close the heavy hook lock tongue, and low operation safety and efficiency, thereby achieving the purpose of improving the degree of automation of heavy hook operations, improving operation efficiency and accuracy, and reducing the risks of high-altitude operations.

[0008] The present invention is achieved through the following technical solutions:

[0009] An adaptive remote control heavy-duty hook lock tongue opening and closing tool comprises a main body mechanism connected to the hook and a toggle actuator mechanism connected to the main body mechanism;

[0010] The main body mechanism includes a support plate, a V-shaped groove provided 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 respectively located at opposite ends of the support plate; the positioning rope is used to be looped around the hook arm; the hook neck clamp is hinged to the support plate;

[0011] The toggle actuator includes a steering gear, a rudder arm connected to an output end of the steering gear, and a toggle rod connected to the rudder arm.

[0012] To address the existing issues of manually opening and closing heavy hook locks, which are associated with low safety and efficiency, the present invention proposes an adaptive remote-controlled heavy hook lock opening and closing tool. The main mechanism is used to connect and install the tool to the hook body, and the actuator is used to open the hook lock. Specifically, the main mechanism includes a support plate, a V-groove, a hook neck clamp, and a positioning rope, wherein:

[0013] As the name implies, the hook neck clamp is a clamp used to clamp the hook neck. The support plate and the hook neck clamp are hinged to each other, so that the V-shaped groove can adaptively contact with the back of different hooks, significantly increasing the adaptability of this application to different heavy hooks and expanding the scope of application; in addition, the self-centering function of the V-shaped groove can be used to achieve the centering contact between the support plate and the back of the hook; the positioning rope is passed around the hook arm during use, thereby ensuring the relative stability between the support plate and the hook arm, and at the same time, after the positioning rope is tightened, the matching stability between the hook back and the V-shaped groove can be ensured to prevent the hook back from falling out of the V-shaped groove. In addition, the material of the positioning rope in this application is not specifically limited here.

[0014] In the toggle actuator, the servo drives the rudder arm to swing, which in turn drives the toggle rod to move, and the toggle rod applies thrust to the hook lock tongue, thereby achieving the purpose of opening the hook lock tongue; when the hook lock tongue needs to be closed, it is only necessary to use the servo to swing the rudder arm to reset it.

[0015] The present application overcomes the problem in the prior art that manual operation is required to open and close the lock tongue of the heavy hook, and can be combined with existing automation technology to realize automatic operation or remote control operation by staff, which significantly improves the degree of automation of heavy hook operation, improves operation efficiency and precision; under frequent lifting conditions (such as derrick disassembly and assembly conditions), it can significantly reduce the workload of operators, improve overall work efficiency, and reduce the risk of high-altitude operations, improve operation safety, and also reduce the error rate during lifting operations, which is conducive to improving operation accuracy; the present application has the ability to cope with different working environments, such as being compatible with heavy hooks of different types and curved structures, has extremely strong adaptability, and expands the scope of application of automated hook operations; the present application does not need to change the existing hook structure when in use, and only needs to be installed on the basis of the existing hook structure, which has extremely strong compatibility and economy.

[0016] The present application can be used in the derrick disassembly and assembly 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.

[0017] Furthermore, the hook neck clamp includes a hook neck front clamp and a hook neck rear clamp that match each other; 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.

[0018] In this solution, a clamping structure similar to a hoop is jointly formed by the front hook neck clamp and the rear hook neck clamp, thereby achieving a stable connection between this application and the hook neck. The rear hook neck clamp is hinged to the support plate. Therefore, when installing this application, first remove the front hook neck clamp, then respectively put the front hook neck clamp and the rear hook neck clamp on both sides of the hook neck, and then connect the front hook neck clamp to the rear hook neck clamp. In this solution, between the front hook neck clamp and the rear hook neck clamp, they can be connected by any existing detachable method, with the principle of not affecting the normal clamping of the hook neck.

[0019] Furthermore, it further includes a tensioning mechanism for tensioning the positioning rope;

[0020] The tensioning mechanism includes a set screw seat fixedly connected to the support plate, a guiding member connected to the set screw seat and / or the support plate, a set screw moving block slidably matched with the guiding member, and a driving component for driving the set screw moving block to slide along the guiding member; the sliding direction of the set screw moving block is perpendicular to the surface of the support plate; both ends of the positioning rope are fixedly connected to the set screw moving block.

[0021] In order to ensure stable installation when this application is applicable to hooks of different model sizes, a tensioning mechanism is specially set. However, traditional tensioning mechanisms are generally realized by winding equipment. Due to the relatively harsh working conditions faced by this application, the positioning rope needs to be made of materials with greater strength, and the difficulty of winding and tensioning is relatively large. Therefore, a special tensioning mechanism is set. Specifically, when the tensioning mechanism of this solution is in use, the driving component drives the set screw moving block to slide along the guiding member. When the set screw moving block moves away from the support plate, the positioning rope is tensioned; when the set screw moving block moves closer to the support plate, the positioning rope is relaxed. Therefore, this solution can flexibly adjust the tensioning degree of the positioning rope according to specific working conditions, so as to adapt to the hook arms of hooks of different model sizes; this tensioning method does not require winding and tensioning, and is more suitable for positioning ropes with high strength and high hardness.

[0022] Furthermore, the driving component includes a tensioning screw threadedly matched with the set screw seat and a clamping piece fixedly connected to the set screw moving block; one end of the tensioning screw is rotatably matched with the clamping piece; the axis of the tensioning screw is parallel to the sliding direction of the set screw moving block.

[0023] In this solution, only by rotating the tensioning screw, the set screw moving block can be driven to move linearly, thereby realizing the tensioning or relaxation of the positioning rope; the driving component of this structure is simple in structure and does not require an additional power source, and can be installed in place through simple manual operation.

[0024] Furthermore, the toggle actuator includes a servo mount for mounting the servo; the servo mount is connected to the main body via a connecting rod. In this solution, the connecting rod connects the toggle actuator to the main body, while also supporting and stabilizing the toggle actuator, thereby ensuring that the toggle actuator can be positioned near the hook lock tongue.

[0025] Furthermore, the main body mechanism also includes a friction disc caliper and a friction disc seat that match each other, and the friction disc seat and the friction disc caliper rotate together and contact each other; the end of the connecting rod away from the servo seat is connected to the friction disc seat.

[0026] In this solution, one end of the connecting rod is connected to the friction disc seat, and the orientation of the friction disc seat is adjusted by rotating it, thereby driving one end of the connecting rod to rotate synchronously, thereby adjusting the angle of the connecting rod and the position angle of the actuator, thereby better adapting to the use of hooks of different models, sizes or types. In addition, in this solution, the friction force between the friction disc caliper and the friction disc seat should be maintained sufficient to ensure that under normal conditions, when the friction disc caliper and the friction disc seat are in close contact, the friction disc seat will not rotate. Of course, if the angular orientation of the friction disc seat needs to be adjusted, the restriction of the friction disc caliper on the friction disc seat can be temporarily released. The friction cooperation between the friction disc caliper and the friction disc seat in this solution can be achieved by any existing technical means and is not specifically limited here.

[0027] Furthermore, the main body mechanism also includes a support seat that slides on the support plate and a support seat fastening screw for temporarily positioning the support seat, and the sliding direction of the support seat is perpendicular to the axis of the V-groove; the friction disc caliper is detachably connected to the support seat.

[0028] In this solution, the friction disc caliper is connected to the support seat. When the support seat slides, the friction disc caliper and the friction disc seat that cooperates with the friction disc caliper also slide synchronously, thereby driving one end of the connecting rod to move. Because the sliding direction of the support seat is perpendicular to the axis of the V-shaped groove, that is, the support seat slides in the horizontal direction of the hook, it can drive one end of the connecting rod to move horizontally, thereby achieving adjustment of the lateral position of the toggle actuator, which is more conducive to adapting to the use of heavy-duty hooks of different models and sizes. Once the support seat is moved to the appropriate position, the support seat is fixed with the support seat fastening screw to prevent it from sliding freely.

[0029] Furthermore, an actuator end connecting rod clamp is provided on the servo seat, and a main body end connecting rod clamp is provided on the friction disc seat;

[0030] The two ends of the connecting rod pass through the execution end connecting rod clamp and the main body end connecting rod clamp respectively.

[0031] The connecting rod is clamped on both sides by the actuator-end connecting rod clamp and the main body connecting rod clamp, ensuring its stability during operation. Both the actuator-end connecting rod clamp and the main body connecting rod clamp are perforated clamps. By adjusting the position of each clamp, the length and distance of the connecting rod extension can be adjusted, thereby adjusting the front and rear position of the actuator to achieve the optimal toggle effect, which is more conducive to adapting to heavy-duty hooks of different models and sizes.

[0032] Furthermore, the main body structure further includes an electrical box located on the support plate. This solution can realize the human-machine interaction and remote control of the present application through the electrical box, and the electrical box has built-in control elements for controlling the operation of the servo.

[0033] A method for installing an adaptive remote control heavy-duty hook lock tongue tool for opening and closing a hook, which is used to install the adaptive remote control heavy-duty hook lock tongue tool of the present application, comprises the following steps:

[0034] S1. Install the hook neck clamp on the hook neck; adjust the orientation of the hook neck clamp so that the V-shaped groove faces the back of the hook and the hook neck clamp clamps the hook neck;

[0035] S2, press down the support plate so that the V-shaped groove is buckled on the back of the hook;

[0036] S3, looping the positioning rope around the hook arm for at least one circle, and tightening the positioning rope;

[0037] S4. Install the toggle actuator so that the toggle rod is located outside the hook lock tongue and directly faces the hook lock tongue.

[0038] Through this solution, the application tool can be installed and tested on the ground, and then used to control the automatic opening and closing of the hook lock tongue.

[0039] Compared with the prior art, the present invention has at least the following advantages and beneficial effects:

[0040] 1.
