Description

Technical Field

[0001] This invention relates to the field of power operation technology, and in particular to a remote clamping control tool and method for a cable identifier. Background Technology

[0002] Cable identification is a common task in cable detection projects. In power system cable identification, when one end of the cable to be identified is a cable terminal pole, the transmitter clamp of the cable identifier needs to be clamped onto the cable above the terminal protection pipe. Since terminal protection pipes are generally quite high (usually 3-5 meters), traditional methods require operators to climb to a high position using an insulated ladder to manually operate the clamp. This is not only inefficient but also poses a safety risk of falls from height due to ladder instability or personnel loss of balance. Furthermore, operational errors during high-altitude operations may damage the cable or terminal protection pipe.

[0003] Most clamping tools currently on the market are fixed-length manual clamps that cannot be remotely controlled; some telescopic clamp structures also have difficulty in accurately controlling the clamping force and cannot be adapted to cable terminal poles of different diameters. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a remote clamping control tool and method for cable identification devices, which enables remote control of the clamping and releasing of cable identification device clamps from the ground, with controllable clamping force, and can be adapted to cable terminal poles of different diameters.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a remote clamping control tool for a cable identifier, including a remote control clamping mechanism, a telescopic support rod, and an operating mechanism. The remote control clamping mechanism is installed at one end of the telescopic support rod, and the operating mechanism is installed at the other end of the telescopic support rod. The remote-controlled clamping mechanism includes a mounting body and a clamping mechanism. The clamping mechanism includes a movable clamp and a fixed clamp. The movable clamp and the fixed clamp are respectively connected to a telescopic support rod through the mounting body. The telescopic support rod is equipped with a locking structure. The movable clamp and the fixed clamp are used to connect to the cable identification device clamp. The operating mechanism is used to control the movable clamp and the fixed clamp to open relative to each other when gripped, and to clamp the movable clamp and the fixed clamp relative to each other when released.

[0006] As a further implementation, the fixed gripper and the movable gripper are arranged sequentially along one end of the telescopic support rod; The fixed gripper and the movable gripper each include a U-shaped groove structure, and the two U-shaped groove structures are arranged opposite to each other.

[0007] As a further implementation, the fixed gripper and the movable gripper are each equipped with a bolt assembly, which is used to fix the cable identification device clamp.

[0008] As a further implementation, the fixed gripper is fixedly connected to the mounting body, and the movable gripper is connected to the mounting body through a rotating mechanism.

[0009] As a further implementation, both the fixed gripper and the movable gripper have anti-slip buffer pads on their inner walls, and pressure sensors are embedded therein. A displacement sensor is installed at the connection between the movable gripper and the mounting body to detect the opening and closing displacement of the movable gripper; an angle sensor is installed at the connection between the fixed gripper and the telescopic support rod to detect the angle between the gripper clamping mechanism and the telescopic support rod.

[0010] As a further implementation, the mounting body includes a mounting body structural component, a structural connector, a movable gripper limiting component or a fixed gripper limiting component, wherein the mounting body structural component is fixed to the telescopic support rod, and the structural connector is fixed to the periphery of the mounting body structural component. The movable gripper limiting component is used to limit the end of the movable gripper, and the fixed gripper limiting component is used to limit the end of the fixed gripper.

[0011] As a further implementation, the operating mechanism includes an operating mechanism body, a fixed handle, a movable handle, and a pull cable. The operating mechanism body is installed at the end of the telescopic support rod, and the fixed handle and the movable handle are installed at a set angle on the side of the operating mechanism body. One end of the pull cable is connected to the movable handle, and the other end passes through the telescopic support rod and is connected to the movable gripper.

[0012] Secondly, embodiments of the present invention also provide a method for using a remote clamping control tool for a cable identifier, including: Adjust the length of the telescopic support rod to meet the required height on site; The cable identifier clamp is set at the movable jaw and the fixed jaw respectively, and the cable identifier clamp is fixed by bolt assembly; Rotate the rotating mechanism to tighten the cable; Grip the operating mechanism firmly to open the cable identification device clamp with the movable and fixed jaws, and place the opened cable identification device clamp on the upper end of the cable protection tube. Release the operating mechanism to allow the cable identifier clamp to grip the cable.

[0013] During the cable identification process, the clamping pressure, jaw position, and clamping angle are collected in real time.

[0014] As a further implementation, when adjusting the telescopic support rod, the overall length of the telescopic support rod is first coarsely adjusted, and then finely adjusted; after adjustment, it is locked by a locking structure.

[0015] The beneficial effects of this invention are as follows: (1) The remote control clamping mechanism of the present invention includes an installation body and a clamping mechanism. The clamping mechanism includes a movable clamp and a fixed clamp. The movable clamp and the fixed clamp are used to connect the cable identification device clamp. The operating mechanism is used to control the movable clamp and the fixed clamp to open relative to each other when gripped, and to clamp the movable clamp and the fixed clamp relative to each other when released. Through the cooperation of the movable clamp and the fixed clamp, the cable identification device clamp can be stably connected, so that the cable identification device clamp can accurately clamp the cable. The operating mechanism adopts the gripping and opening and releasing clamping method to reduce the difficulty of operation. The telescopic support rod connects the remote control clamping mechanism and the operating mechanism, and can flexibly adjust the length to realize high-altitude remote operation.

[0016] (2) The movable gripper and the fixed gripper of the present invention are connected to the telescopic support rod through the mounting body. The mounting body has a gripper support limiting component for limiting the end of the movable gripper and the fixed gripper. The U-shaped groove structure of the movable gripper and the fixed gripper can achieve the initial fixation of the cable identification device clamp, and then the cable identification device clamp can be stably installed with the bolt assembly. Then, the movable gripper and the fixed gripper can be precisely controlled by the pull wire traction. Attached Figure Description

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0022] This embodiment provides a remote clamping control tool for a cable identifier, such as... Figure 1 As shown, the device includes a remote control clamping mechanism, a telescopic support rod 3, and an operating mechanism 4. The remote control clamping mechanism is connected to one end of the telescopic support rod 3, and the operating mechanism 4 is connected to the other end of the telescopic support rod 3. The remote control clamping mechanism is used to install the cable identification device clamp. The operating mechanism 4 controls the remote control clamping mechanism, thereby enabling remote control of the cable identification device clamp.

[0023] The remote-controlled clamping mechanism initially secures the cable identifier clamp, and then the bolt assembly 2-4 reinforces the clamp. For example... Figure 2 and Figure 3 As shown, the remote control clamping mechanism includes a mounting body 1 and a gripper clamping mechanism 2. The mounting body 1 is mounted on the telescopic support rod 3, and the gripper clamping mechanism 2 is connected to the mounting body 1. The operating mechanism 4 controls the action of the gripper clamping mechanism 2 by controlling the gripper structure.

[0024] like Figure 1 and Figure 2 As shown, the gripper holding mechanism 2 includes a movable gripper 2-1 and a fixed gripper 2-2. The fixed gripper 2-2 and the movable gripper 2-1 are arranged sequentially along the top of the telescopic support rod 3. The fixed gripper 2-2 and the movable gripper 2-1 are respectively connected to the telescopic support rod 3 through a mounting body 1. The fixed gripper 2-2 is fixedly connected to the mounting body 1, and the movable gripper 2-1 is rotatably connected to the mounting body 1.

[0025] The fixing jaws 2-2 work in conjunction with the mounting body 1 to secure the cable identification device clamp and provide a supporting reference surface for the clamp. For example... Figure 3 As shown, the fixed gripper 2-2 includes a connecting plate 2-2-1 and a mounting support plate 2-2-2. The connecting plate 2-2-1 is fixedly connected to the mounting body 1, and the mounting support plate 2-2-2 is fixed to one side of the connecting plate 2-2-1. In this embodiment, the mounting support plate 2-2-2 has a U-shaped groove structure with a supporting reference surface on its inner side for supporting one end of the cable identification device clamp. The supporting reference surface has a mounting hole 2-2-3 on the side near the connecting plate, and the bolt assembly 2-4 passes through the mounting hole 2-2-3 to connect the cable identification device clamp to the fixed gripper 2-2.

[0026] like Figure 2 As shown, the movable gripper 2-1 has the same structure as the fixed gripper 2-2, with their U-shaped groove structures positioned opposite each other. The difference lies in that the connecting plate of the movable gripper 2-1 is connected to the mounting body 1 via a rotating mechanism 2-3. Under the driving action of the operating mechanism 4, the movable gripper 2-1 can rotate relative to the mounting body 1. The movable gripper 2-1 serves two purposes: firstly, it secures the other end of the cable identification device clamp to prevent it from falling off; secondly, the rotating mechanism 2-3 enables the clamping and releasing of the cable identification device clamp.

[0027] In this embodiment, as Figure 3 As shown, the bolt assembly 2-4 includes a bolt and a nut. The bolt passes through the mounting hole of the movable jaw 2-1 or the fixed jaw 2-2 and is locked in place by the nut. The rotating mechanism 2-3 can be implemented using a structure such as a bearing.

[0028] The U-shaped groove structure of the movable gripper 2-1 and the fixed gripper 2-2 in this embodiment can initially fix the cable identification device transmitter clamp, and then, together with the bolt assembly 2-4, achieve stable installation of the cable identification device clamp. Finally, the movable gripper 2-1 and the fixed gripper 2-2 can be precisely controlled by the pull wire 4-4.

[0029] In this embodiment, an anti-slip buffer pad is provided in the U-shaped groove to increase the clamping stability of the cable identification device transmitter clamp; at the same time, a pressure sensor is embedded in the U-shaped groove to collect the clamping pressure data of the gripper on the cable identification device transmitter clamp and cable in real time. The pressure data is transmitted to the controller, which can realize precise control of the clamping force.

[0030] Mounting body 1 is used to connect the gripper holding mechanism 2, the telescopic support rod 3, and the operating mechanism 4, and is also used for positioning the cable identifier clamp. For example... Figure 2As shown, the mounting body 1 includes a mounting body structural component 1-1, a structural connector 1-2, and a gripper support and limiting component 1-3. The mounting body structural component 1-1 serves as the main structure of the mounting body 1 and also guides the movement of the gripper holding mechanism 2. In this embodiment, the mounting body structural component 1-1 adopts a clamp structure. After the clamp structure is fastened to the telescopic support rod 3, it is locked and fixed with bolt assembly 2-4.

[0031] like Figure 2 As shown, structural connector 1-2 is fixed to the periphery of mounting body structural component 1-1. In this embodiment, structural connector 1-2 is located on the opposite side of the clamp structure connection end. Structural connector 1-2 is a rectangular block structure, which is connected to movable gripper 2-1 and fixed gripper 2-2, providing axial end limiting for the gripper. Movable gripper 2-1 and fixed gripper 2-2 are connected to the end of structural connector 1-2 away from mounting body structural component 1-1. Fixed gripper 2-2 is fixedly connected to its corresponding structural connector 1-2, while movable gripper 2-1 is connected to its corresponding structural connector 1-2 via a rotating mechanism 2-3.

[0032] The gripper support limiting component 1-3 includes a movable gripper limiting component and a fixed gripper limiting component. The movable gripper limiting component is located at one end of the movable gripper 2-1 and is used to limit the end of the movable gripper 2-1 when the fixture is installed. The fixed gripper limiting component is located at one end of the fixed gripper 2-2 and is used to limit the end of the fixed gripper 2-2 when the fixture is installed.

[0033] The remote clamping control tool in this embodiment is also equipped with a position sensing component, which includes a displacement sensor and an angle sensor. The displacement sensor is installed at the connection between the movable gripper 2-1 and the mounting body 1 to detect the opening and closing displacement of the movable gripper 2-1. The angle sensor is installed at the connection between the fixed gripper 2-2 and the telescopic support rod 3 to detect the angle between the gripper clamping mechanism 2 and the telescopic support rod 3, so as to provide real-time feedback on the clamping position status.

[0034] like Figure 4 As shown, the telescopic support rod 3 includes a telescopic rod body 3-1 and a locking structure 3-2. The telescopic rod body 3-1 includes a first rod segment and a second rod segment, which form a telescopic structure. In this embodiment, the diameter of the first rod segment is smaller than the diameter of the second rod segment, and the first and second rod segments are connected by a threaded connection to achieve length adjustment. The first rod segment is connected to the gripper holding mechanism 2, and the second rod segment is connected to the operating mechanism 4. The locking structure 3-2 is installed on the first rod segment, and the first and second rod segments are locked by the locking structure 3-2. To reduce the overall weight, the first and second rod segments are hollow inside. It is understood that the first and second rod segments can also be telescopically extended in other ways.

[0035] In this embodiment, the locking structure 3-2 includes a clamp, a bolt, and a nut. The clamp is fixed between the upper support rod and the lower support rod. The connection and fixation between the upper support rod and the lower support rod are achieved through the cooperation of the bolt and the nut.

[0036] The first segment has a first connecting part 3-3 at the end away from the second segment, and the second segment has a second connecting part 3-4 at the end away from the first segment. The diameters of the first connecting part 3-3 and the second connecting part 3-4 are both smaller than the diameters of the corresponding segments, which are used to realize the installation of the corresponding mounting body 1 and operating mechanism 4.

[0037] like Figure 5 As shown, the operating mechanism 4 includes an operating mechanism body 4-1, a fixed handle 4-3, a movable handle 4-2, and a pull cable 4-4. The operating mechanism body 4-1 is a sleeve structure, fitted onto the outside of the second connecting part 3-4. The fixed handle 4-3 is circumferentially disposed on the side of the operating mechanism body 4-1. The movable handle 4-2 is also circumferentially disposed on the operating mechanism body 4-1, forming a certain angle with the fixed handle 4-3, forming a structure similar to a hand gripper. The fixed handle 4-3 is provided with a handle limiting member 4-5. When the movable handle 4-2 contacts the handle limiting member 4-5, it is the minimum opening angle of the movable handle 4-2 relative to the fixed handle 4-3.

[0038] The movable handle 4-2 is rigidly connected to one end of the metal pull wire 4-4, and the other end of the metal pull wire 4-4 passes through the telescopic support rod 3 and is rigidly connected to the movable gripper 2-1. When the movable handle 4-2 is moved, the movable gripper 2-1 moves accordingly. By holding the movable handle 4-2 and the fixed handle 4-3 and applying a gripping force, the movement of the movable gripper 2-1 can be remotely controlled to achieve clamping and releasing of the clamp, reducing the difficulty of operation. Example

[0039] This embodiment provides a method for using a remote clamping control tool for a cable identifier, based on the remote clamping control tool described in Embodiment 1, including the following steps: Step 1: Assemble and adjust the telescopic support rod 3.

[0040] First, connect the first and second pole segments so that the overall length of the telescopic support rod 3 roughly meets the required height on site. Then, rotate the first pole body to fine-tune the length of the telescopic support rod 3 using the threaded connection, ensuring it meets the required height. Finally, use clamps and bolts to secure the connection between the first and second pole segments, tightening the bolts to provide secondary reinforcement.

[0041] Step 2: Install the cable identification device clamp.

[0042] First, place both ends of the cable identifier clamp at the movable jaw 2-1 and the fixed jaw 2-2 respectively for initial fixation. Then, gradually slide both ends of the clamp into the U-shaped grooves of the movable jaw 2-1 and the fixed jaw 2-2, fasten the hinge inside the U-shaped groove, use the locking tongue to fasten the hinge in the U-shaped groove, and tighten the bolts to fix the hinge in the U-shaped groove, thereby fixing both ends of the cable identifier clamp.

[0043] Step 3: Rotate the rotating mechanism 2-3 clockwise until the pull line 4-4 is tightened.

[0044] Step 4: Hold the operating mechanism 4, grip the movable handle 4-2 and the fixed handle 4-3 to open the clamp, adjust the telescopic support rod 3 to an upright position with a height exceeding the height of the cable protection pipe, clamp the opened cable identification device clamp onto the upper cable of the cable protection pipe, release the operating mechanism 4 to fix the clamp, and start the cable identification and detection work.

[0045] During the cable identification operation, the clamping pressure, gripper position, and clamping angle are collected in real time. Furthermore, during the clamping operation, the angle sensor detects the angle between the gripper clamping mechanism 2 and the telescopic support rod 3 in real time. If the angle deviates (i.e., the clamping position deviates from the preset angle), the main controller issues a warning signal through the status display panel and simultaneously sends a reminder message to the portable terminal through the wireless communication module, prompting the operator to adjust the angle of the telescopic support rod 3.

[0046] Step 5: After the cable identification and detection work is completed, operate the operating mechanism 4 to make the movable handle 4-2 and the fixed handle 4-3 control the clamp to open again, remove the cable identification device clamp from the cable, and lower the telescopic support rod 3 to disassemble the tool, thus completing this work.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
