Description

Technical Field

[0001] This utility model belongs to the technical field of circuit construction tools, and specifically relates to an electric insulated wire tensioner. Background Technology

[0002] Wire tensioners are used to tighten conductors during overhead power line installation. Currently, wire tensioners are mainly divided into two types: manual wire tensioners and electric insulated wire tensioners. Manual wire tensioners are ratchet-type tensioners, such as manual boat-type tensioners, manual double-hook tensioners, manual insulated tensioners, and lever hoists. They all use a ratchet mechanism for manual operation to tighten and reel in the conductor. Electric insulated wire tensioners utilize a motor to move the hook, thereby tightening and reeling in the conductor. Compared to manual tensioners, electric insulated wire tensioners are more efficient, require less labor, and are beneficial for high-altitude operations, making them more popular with consumers.

[0003] Existing electric insulated wire tensioners, as shown in patent application number CN201821160456.4 entitled "Wire Tensioner for Power Line Construction," mainly include a housing and a front hook and a rear hook mounted on the housing. The rear hook is mounted on a rope, and the rope is wound or unwound via a rotating roller rotatably connected to the housing. A worm gear is connected to the rotating roller, and the worm gear meshes with a worm. The worm is driven by a servo motor fixed to the housing. When the servo motor operates, it drives the worm to rotate, which in turn drives the worm gear and the rotating roller to rotate, thus winding or unwound the rope to tighten and retract the wire connected to the rear hook.

[0004] In the aforementioned patent, the winding distance of the electric insulated wire tensioner is achieved by manually controlling the start and stop of the servo motor. However, the manual control of the servo motor is based on manually observing the tension of the wire. Since human observation is prone to error, the current electric insulated wire tensioner is not easy to control the tension of the wire. Utility Model Content

[0005] The purpose of this invention is to provide an electric insulated wire tensioner with an added tension sensor, which ensures that the electric insulated wire tensioner has almost the same tension and sag consistency every time it is used. Furthermore, the tension sensor can detect the magnitude of the tension, making the wire tensioner of this application more suitable for use with wires that require different tension levels.

[0006] This utility model provides an electric insulating wire tensioner, which includes a mounting component, a drive mechanism, a movable hook, and a fixed hook movably connected to the mounting component.

[0007] The drive mechanism includes a rotating roller rotatably connected to the mounting component, a pressure roller connected to the mounting component, and a drive assembly, wherein the drive assembly is connected to the mounting component and is used to drive the rotating roller to rotate;

[0008] A cable is wound around the rotating roller, and the other end of the cable is fixed to the pressure roller. A movable hook is sleeved on the cable.

[0009] The pressure roller is equipped with a tension sensor to detect the tension of the cable.

[0010] The principle of this invention:

[0011] The fixed hook and the movable hook are respectively fixed to the conductor that needs to be tensioned. The rotating roller is driven by the drive assembly to rotate. The rotating roller rotates to wind or unwind the cable, and to retract or loosen the cable. The movable hook sleeved on the cable can move closer to or away from the fixed hook, so that the electric insulated wire tensioner of this utility model can perform wire retraction and tensioning operations on the conductor used with it.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, one end of the cable is fixed to the pressure roller. During the cable winding process, the tension force on the wire fixed on the movable hook is transmitted to the cable, and the resistance on the cable is transmitted to the pressure roller. The pressure roller is equipped with a tension sensor, which can determine the tension of the wire fixed by the movable hook (or fixed hook) and thus determine whether the rotating roller should be rotated or stopped, ensuring that the tension of the wire is appropriate and more accurate than manual observation.

[0014] Furthermore, the mounting hardware is equipped with a protective element to intercept the position of the movable hook.

[0015] Furthermore, the protective component includes a baffle and a position sensor that works in conjunction with the baffle. The baffle is fixed to the mounting component to intercept the movable hook.

[0016] Furthermore, the drive assembly includes a driver and a worm gear and worm shaft used in conjunction. The driver is fixed to the mounting component and is used to drive the worm shaft to rotate. The worm gear and the rotating roller are coaxially arranged.

[0017] Furthermore, the rotating roller is equipped with an anti-rotation component.

[0018] The anti-rotation assembly includes a rotating gear that rotates in the same direction or opposite direction as the rotating roller and an anti-rotation sensor for detecting the rotation direction of the rotating gear. The anti-rotation sensor is fixed to the mounting component.

[0019] Furthermore, the mounting component is also equipped with a controller, which is connected to the tension sensor and drive assembly, and the controller has at least one button.

[0020] Furthermore, it also includes a remote control, and signal connections between the remote control and the controller.

[0021] Furthermore, it also includes a battery assembly, which is fixed to the mounting bracket and used for power supply.

[0022] Furthermore, both the fixed hook and the movable hook include a mounting part and a hook-shaped connecting part.

[0023] The hook-shaped connector has an open end with a matching elastic card, so that the hook-shaped connector has a ring-shaped hook structure. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0032] like Figures 1 to 4 As shown, an electric insulated wire tensioner includes a mounting component 100, a drive mechanism, a movable hook 110, and a fixed hook 120 movably connected to the mounting component 100. The drive mechanism includes a rotating roller 180 rotatably connected to the mounting component 100, a pressure roller 170 connected to the mounting component 100, and a drive assembly 150. The drive assembly 150 is connected to the mounting component 100 and is used to drive the rotating roller 180 to rotate. A cable 130 is wound around the rotating roller 180, and the other end of the cable 130 is fixed to the pressure roller 170. The movable hook 110 is sleeved on the cable 130. A tension sensor is provided on the pressure roller 170 to detect the tension of the cable 130.

[0033] Understandably, the mounting component 100 serves as a fixing part of the entire device to facilitate the installation of various components. The mounting component 100 can be shell-shaped or a slotted frame structure. In this application, to facilitate the layout and installation of various components, such as... Figure 2 , 3 As shown in Figure 4, the mounting component 100 is generally similar to a groove-shaped structure (a rectangular cavity structure with openings at both ends). The fixed hook 120 is located at one end of the groove length direction of the mounting component 100 and is connected to the mounting component 100. The movable hook 110 is located at the other end of the groove length direction of the mounting component 100 and is at least partially located outside the mounting component 100.

[0034] The rotating roller 180 is mounted between the two grooved sidewalls of the mounting member 100 and is rotatably connected to the mounting member 100 via bearings or other connecting components. The drive assembly 150 is fixed to the outside of the mounting member 100 and is used to drive the rotating roller 180 to rotate. The drive assembly 150 can be a servo motor, stepper motor, etc., and can directly drive the rotation of the rotating roller 180; alternatively, the drive assembly 150 can be a structure composed of a motor and transmission components to achieve the rotation of the rotating roller 180. The rotation of the rotating roller 180 enables winding or unwinding of the cable 130 wound on it. To facilitate the winding and unwinding of the cable 130 by the rotating roller 180, a winch 181 coaxially mounted on the rotating roller 180 can be used to facilitate the winding and unwinding of the cable 130.

[0035] The pressure roller 170 and the rotating roller 180 are staggered to facilitate the tensioning of the cable 130. The pressure roller 170 can be positioned above or below the rotating roller 180, and can be positioned between the fixed hook 120 and the rotating roller 180, or between the movable hook 110 and the rotating roller 180. In this application, the pressure roller 170 is located below the rotating roller 180 and between the rotating roller 180 and the movable hook 110; the pressure roller 170 and the rotating roller 180 are parallel and fixed to the mounting member 100.

[0036] The pressure roller 170 and the tension sensor can be connected in various ways, including: the tension sensor and the pressure roller 170 are an integral structure; the tension sensor can also be located at the connection point between the pressure roller 170 and the cable 130; the tension sensor can also be located at the end of the pressure roller 170. In use, the tension sensor can detect the pressure on the cable 130. In this application, the tension sensor and the pressure roller 170 are an integral structure, that is, the pressure roller 170 in the figure is also a tension sensor.

[0037] The tension cable 130 can be made of steel wire rope, insulating braided tape, etc. In this application, to enhance the overall insulation effect, the tension cable 130 is made of insulating braided tape. One end of the tension cable 130 is fixed to the rotating roller 180 and wound along the rotating roller 180. The other end of the tension cable 130 is fixed to the pressure roller 170. The movable hook 110 is sleeved on the tension cable 130. When the rotating roller 180 rotates, the fixed hook 120 and the movable hook 110 move relative to each other. This relative movement of the fixed hook 120 and the movable hook 110 causes tension to be applied to the pressure roller 170. The magnitude of the tension can be detected by a tension sensor. In use, the tension can be displayed in real time on a display screen (the controller's display screen), or the tension can be monitored and the tension value set through other software programming (PLC programming). The tensioning tool automatically stops when the predetermined tension is reached, ensuring the consistency of tension and sag for each tensioning operation; or, the displayed tension value can be used to adapt to the use of different wires.

[0038] Fixed hook 120 and movable hook 110 need to be attached to wires or other structures during use. When fixed hook 120 and movable hook 110 are connected to wires, they are actually connected to a loop structure formed by knotting the wires. In this process, conventional hook structures have the risk of wire detachment. Therefore, this application improves the structure of fixed hook 120 and movable hook 110. Specifically, both fixed hook 120 and movable hook 110 of this application include a mounting part and a hook-shaped connecting part. The open end of the hook-shaped connecting part is provided with a matching elastic clip, so that the hook-shaped connecting part has a ring-shaped pull hook structure. The long end of the hook-shaped connecting part is rotatably connected to the mounting part, and the elastic clip is movably connected to the hook-shaped connecting part through a torsion spring, so that the hook-shaped connecting part with the elastic clip is similar to the existing safety hook structure, thereby reducing the risk of hook-shaped connecting part and guide wire detachment.

[0039] For illustrative purposes, in this embodiment, the mounting portion, hook-shaped connecting portion, and elastic clip of the fixed hook 120 are respectively a fixed mounting portion 121, a fixed hook-shaped connecting portion 123, and a fixed elastic clip 122; the mounting portion, hook-shaped connecting portion, and elastic clip of the movable hook 110 are respectively a movable mounting portion 111, a movable hook-shaped connecting portion 113, and a movable elastic clip 112. Figure 1 , 2 As shown, the fixed mounting part 121 of the fixed hook 120 is rotatably connected to the mounting part 100 via a shaft pin; the movable mounting part 111 of the movable hook 110 is provided with a connecting pin 114, and the cable 130 passes through the connecting pin 114 to achieve its connection with the movable hook 110.

[0040] During the take-up process, the movable hook 110 moves towards the mounting member 100. Due to the mounting positions of the pressure roller 170 and the rotating roller 180 on the mounting member 100, if the innermost take-up position of the movable hook 110 on the mounting member 100 is not limited, the movable hook 110 will continue to move, potentially damaging the equipment. To avoid this problem, this application provides a protective member 160 within the mounting member 100 to intercept the position of the movable hook 110. As a result of the movable hook 110, the protective member 160 effectively restricts the position of the movable mounting part 111 on the mounting member 100, preventing the movable mounting part 111 from continuously retracting and damaging the equipment.

[0041] In this application, the protective component 160 includes a baffle 161 and a position sensor 162 that cooperates with the baffle 161. The baffle 161 is fixed to the mounting component 100 and is used to intercept the movable hook 110. Figure 3 , 4As shown, baffle 161 is fixed near the end of the mounting member 100. Baffle 161 is fixed to both sides of the two grooved sidewalls of the mounting member 100. Baffle 161 is used to intercept the fixed mounting portion 121 of the movable hook 110. Position sensor 162 is connected to baffle 161. Position sensor 162 can be an infrared light sensor or a contact sensor, and its purpose is to detect the deepest position of the movable hook 110 retracted into the mounting member 100. During the tightening process, when the insulating braided tape (cable 130) is about to be completely retracted into the tool, the movable mounting portion 111 of the movable hook 110 will trigger the tightening in-place protection device, and the equipment will automatically stop to avoid equipment damage.

[0042] To prevent the rotating roller 180 from continuing to rotate after the cable 130 has been released to its maximum position, this application includes a position sensor 154 on the mounting component 100. This sensor detects the thickness of the rotating roller 180 (winch 181) when the cable has been released to its maximum slack position. During use, the slack-position protection device is triggered after the insulated braid (cable 130) tape is fully released, automatically stopping the equipment and effectively ensuring the safety of the equipment and operators.

[0043] To achieve the rotation of the rotating roller 180, the drive assembly 150 of this application includes a driver 153 and a worm gear 152 and a worm 151 used in conjunction. The driver 153 is fixed to the mounting part 100 and is used to drive the worm gear 151 to rotate. The worm gear 152 is coaxially arranged with the rotating roller 180. The driver 153 is a servo motor or a stepper motor to facilitate control of the rotation direction and start / stop of the rotating roller 180. The driver 153 can be directly coaxially arranged with the worm gear 151, or it can be connected to the worm gear 151 through a coupling and / or a reducer. The reducer can be a planetary gear reducer or other reducers found in the prior art, used to reduce the speed of the driver 153, which can improve the safety of the electric insulated wire tensioner. The power transmission method between the worm gear 152 and the worm 151 can only be that the rotation of the worm 151 drives the rotation of the worm gear 152, while the rotation of the worm gear 152 cannot drive the rotation of the worm 151. Therefore, even if the driver 153 fails during use, the cable 130 on the rotating roller 180 will not loosen when there is tension on the movable hook 110, thus ensuring the safety of the electric insulated tensioner.

[0044] To further detect the rotation direction of the rotating roller 180, this application provides an anti-rotation component 155 on the rotating roller 180. The anti-rotation component 155 includes a rotating gear 1551 that rotates in the same or opposite direction as the rotating roller 180 and an anti-rotation sensor 1553 for detecting the rotation direction of the rotating gear 1551. The anti-rotation sensor 1553 is fixed to the mounting component 100. The rotating gear 1551 and the worm gear 152 are respectively disposed on both sides of the rotating roller 180. The rotating gear 1551 can be coaxially disposed with the rotating roller 180 and rotate in the same direction. The rotating gear 1551 and the rotating roller 180 can also be reversed by other transmission gears. Regardless of whether the rotating gear 1551 and the rotating roller 180 rotate in the same or opposite direction, the anti-rotation sensor 1553 can detect the rotation direction (or the opposite direction) of the rotating roller 180 according to the settings. Figure 3 As shown in this application, a small gear 1552 is coaxially arranged at the end of the rotating roller 180. The small gear 1552 meshes with the rotating gear 1551. The rotating gear 1551 is rotatably connected to the mounting component 100 in a suspended manner. An anti-rotation sensor 1553 is mounted on both sides of the rotating gear 1551 to detect the reverse rotation of the rotating gear 1551. The anti-rotation component 155 can detect the reverse rotation of the rotating roller 180. In the event of a failure of the self-locking mechanism of the worm gear 152 and worm 151, the anti-rotation component 155 can assist the operator in determining whether the equipment is damaged, further increasing the safety of the equipment.

[0045] For starting and stopping the actuator 153, the mounting component 100 also includes a controller. The controller is connected to the tension sensor, actuator 153, position sensor 162, end-position sensor 154, and anti-rotation sensor 1553. The controller has at least one button 141. In this application, the controller is designed and installed together with the battery assembly 140; therefore, the position of the controller is not shown in the figures. The number of buttons 141 can be set according to the usage environment of the device. If the device can directly control the start, stop, and rotation direction of the rotating roller 180 through each button 141, then each control button 141 can include a start / stop button 141, a loosening button 141, and a tightening button 141, etc. If the device can be controlled by a remote control 200, then only one power switch button 141 is needed on the controller; other operation buttons 141 or touch screen control modules can be set on the remote control 200. In this application, only one power switch button 141 is provided on the mounting component 100.

[0046] To facilitate remote high-altitude operation of this electric insulated wire tensioner, this invention also includes a remote controller 200, which is connected to the controller. The controller has a power connection terminal, and the controller and remote controller 200 are connected via an RS485 bus. The remote controller 200 has the aforementioned function buttons 141. By controlling these buttons, the electric insulated wire tensioner can be operated to tighten and retract the wire. Alternatively, the controller and remote controller 200 can also be wirelessly connected, allowing the device to operate via the function buttons 141 on the remote controller 200. Correspondingly, a display screen can be installed on the remote controller 200 to show data detected by the tension sensor. It can also display data detected by other sensors, facilitating comprehensive monitoring and use of the equipment by the operator.

[0047] To ensure the proper functioning of the actuator 153, the tension sensor, the controller, and all other sensors, this invention also includes a battery assembly 140, such as... Figure 1 , 2 As shown, the battery assembly 140 is fixed below the mounting component 100. The casing of the battery assembly 140 can prevent the battery box from exploding, improving the safety of the battery assembly 140 in use. The battery assembly 140 is connected to corresponding components via wiring harnesses, facilitating the use of each component.

[0048] The principle of this invention:

[0049] The fixed hook 120 and the movable hook 110 are fixed to the conductors that need to be tensioned. The driver 153 works, and through the worm gear 151 and worm wheel 152, it drives the rotating roller 180 to rotate. The rotating roller 180 rotates to wind or unwind the cable 130, and performs the winding or loosening operation of the cable 130. The movable hook 110, which is sleeved on the cable 130, can move closer to or away from the fixed hook 120, so that the electric insulated wire tensioner of this utility model can perform winding and tensioning operations on the conductors used with it.

[0050] In this invention, one end of the cable 130 is fixed to the pressure roller 170. When the cable 130 is being wound up, the tension force on the wire fixed on the movable hook 110 is transmitted to the cable 130, and the resistance on the cable 130 is transmitted to the pressure roller 170. The pressure roller 170 is equipped with a tension sensor, which can determine the tension of the wire fixed by the movable hook 110 (or the fixed hook 120), thereby determining whether the rotating roller 180 should rotate or stop, ensuring that the tension of the wire is appropriate and more accurate than manual observation.

[0051] It is worth noting that the intelligent control principle of the remote controller 200 of this utility model can refer to the content described in the applicant's earlier patent application with patent number CN202310822726.2 entitled "An Integrated Improved Intelligent Electric Insulating Wire Tightener and Its Tightening Method", ensuring that the electric insulating wire tightener can achieve high-altitude operation through remote control.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the spirit of this utility model should be included within the protection scope of this utility model.
