Description

Technical Field

[0001] This utility model relates to the field of power transmission line sealing technology, and more specifically, to a power transmission line sealing mechanism that automatically goes online. Background Technology

[0002] Transmission line crossing enclosures are an important technical means in power construction. In the construction of power transmission lines, it is inevitable to cross other important facilities (such as railways, highways, high-voltage lines, etc.). In order to ensure construction safety and the normal operation of the facilities being crossed, it is necessary to erect crossing enclosures to protect the objects being crossed.

[0003] Traditional cross-lined enclosure systems involve workers climbing onto the power lines to erect the system, then using the enclosure to lift and lay the insulating netting. This method is not only labor-intensive but also time-consuming, costly, and inefficient. Furthermore, using existing cross-lined enclosure systems poses significant safety risks and hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide an automatic online transmission line sealing mechanism. This transmission line sealing mechanism can realize the rapid and safe raising of the insulation net through the online mechanism, and can also realize the rapid laying of the insulation net, thereby reducing construction costs and improving the efficiency of crossing the sealing net.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic power transmission line sealing mechanism, characterized in that it comprises several sealing devices and insulating ropes that are pulled and hung to the power transmission line conductors by the online mechanism; each sealing device includes a main body, a traveling assembly with traveling wheels, a winching assembly with two winches, and a hook for hanging the insulating net; the traveling assembly is mounted on the main body; the winching assembly is connected to the main body and the two winches are located on opposite sides of the main body; the hook is connected to the winching assembly; the number of insulating ropes is the same as the number of sealing devices; the two ends of the insulating ropes hung to the conductors are respectively wound around the two winches.

[0006] In the above scheme, this utility model can use the upper mechanism to pull the insulating rope to hang the conductor of the transmission line. In each sealing device, the rotation of two winches causes the sealing device to rise through the insulating rope and hang the conductor of the transmission line through the traveling wheels, thereby realizing the rapid and safe rise of the insulating net. By controlling the movement of the traveling wheels of each sealing device, the insulating net can be quickly unfolded and laid, thereby greatly improving the efficiency of crossing the sealing net and reducing construction costs and construction safety risks.

[0007] The walking assembly also includes a walking arm and a walking wheel drive; the walking arm is connected to the main body, and the walking wheel is rotatably mounted on the walking arm; the walking wheel drive is mounted on the walking arm and connected to the walking wheel to drive the walking wheel to rotate.

[0008] The winch assembly also includes a winch wheel drive component; the winch wheel drive component is connected to the main body and to the winch wheels respectively, so as to drive the two winch wheels to rotate forward or in reverse.

[0009] The winch drive unit simultaneously drives two winches to rotate forward, causing the insulating rope to be wound up, thus raising the main body; the winch drive unit simultaneously drives two winches to rotate in reverse, causing the insulating rope to be unwound, thus lowering the main body.

[0010] Each sealing device also includes a guide for guiding the wires to the walking wheels as the sealing device climbs; the guide is provided with an inclined surface and is located at the top of the main body.

[0011] Each sealing device also includes a dual-axis motor for connection to the main body, a lifting ring assembly for preventing interference and friction between the insulating rope and the wire, and a locking assembly for locking the wire on the traveling wheel; the dual-axis motor is mounted on the main body and connected to the lifting ring assembly and the locking assembly respectively, so that the dual-axis motor can drive the lifting ring assembly and the locking assembly to move simultaneously.

[0012] The lifting ring assembly includes a lifting ring, a gear, and a rack; the rack is connected to the lifting ring; the gear is connected to a dual-shaft motor and meshes with the rack; during operation, the dual-shaft motor drives the gear to rotate, causing the rack to rise and fall, thereby driving the lifting ring to rise and fall.

[0013] The insulated rope that is attached to the conductor is threaded through the raised ring.

[0014] The locking assembly includes a rocker arm with transmission teeth and a second gear; the second gear is connected to a dual-shaft motor and meshes with the transmission teeth; during operation, the dual-shaft motor drives the second gear to rotate, thereby driving the rocker arm to rotate through the transmission teeth.

[0015] The dual-axis motor simultaneously drives the lifting ring to rise and the swing arm to rotate, causing the lifting ring to raise the area where the insulating rope and the swing arm, along with the traveling wheels, form the conductor. The dual-axis motor also simultaneously drives the lifting ring to descend and the swing arm to rotate back to its original position, causing the insulating rope to descend and the swing arm to open. After the insulating rope descends, it facilitates the subsequent detachment of the sealing netting device from the conductor.

[0016] The advantages of this automatic online transmission line sealing mechanism are:

[0017] 1. No need for manual tower climbing to hang the device on the conductor: Using drones or other online mechanisms to pull insulated ropes around the conductor to form a lifting track for each sealing device, improving the efficiency and safety of online installation of the sealing device, while reducing the risk of manual operation.

[0018] 2. Multifunctional design of the hanging end device: Each sealing device includes a lifting ring assembly, guide components, traveling wheels, traveling wheel drive components, and locking components. All components work together to complete the operation of hanging the sealing device, hanging, laying the insulating net, and unhanging the wire.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects: The automatic online transmission line sealing mechanism of the present invention can realize the rapid and safe raising of the insulation net through the online mechanism, and can also realize the rapid laying of the insulation net, thereby reducing construction costs and improving the efficiency of crossing the sealing net.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0026] like Figures 1 to 4As shown, the automatic power transmission line sealing mechanism of this utility model includes several sealing devices 1 and insulating ropes 3 that are pulled and hung to the conductors 2 of the power transmission line by a drone or other onboarding mechanism. Each sealing device includes a main body 4, a traveling assembly with traveling wheels 5, a winching assembly with two winches 6, and a hook 7 for hanging the insulating net. The traveling assembly is mounted on the main body 4; the winching assembly is connected to the main body 4, and the two winches 6 are located on both sides of the main body 4. The hook 7 of this utility model is connected to the winching assembly, and the number of insulating ropes 3 is the same as the number of sealing devices 1; the two ends of the insulating ropes 3 hung to the conductors 2 are respectively wound around the two winches 6.

[0027] Specifically, the walking assembly also includes a walking arm 8 and a walking wheel drive 9. The walking arm 8 is connected to the main body 4, the walking wheel 5 is rotatably mounted on the walking arm 8, and the walking wheel drive 9 is mounted on the walking arm 8 and connected to the walking wheel 5 to drive the walking wheel 5 to rotate.

[0028] The winch assembly of this utility model also includes a winch wheel drive component 10, which is connected to the main body 4 and to the winch wheels 6 respectively, enabling the two winch wheels 6 to rotate forward or in reverse. When the winch wheel drive component 10 simultaneously drives the two winch wheels 6 to rotate forward, it causes the insulating rope 3 to be wound up, causing the main body 4 to rise; when the winch wheel drive component 10 simultaneously drives the two winch wheels 6 to rotate in reverse, it causes the insulating rope 3 to be unwound, causing the main body 4 to descend.

[0029] Each sealing device also includes a guide 11 for guiding the wire 2 to the walking wheel 5 when the sealing device is climbing. The guide 11 is provided with an inclined surface and is located on the top of the main body 4.

[0030] Each sealing device also includes a dual-axis motor 12 for connection to the main body 4, a lifting ring assembly for preventing interference and friction between the insulating rope 3 and the wire 2, and a locking assembly for locking the wire 2 on the traveling wheel 5. The dual-axis motor 12 is mounted on the main body 4 and connected to the lifting ring assembly and the locking assembly respectively, so that the dual-axis motor 12 can drive the lifting ring assembly and the locking assembly to move simultaneously.

[0031] Specifically, the lifting ring assembly includes a lifting ring 13, a gear 14, and a rack 15. The rack 15 is connected to the lifting ring 13, and the gear 14 is connected to a dual-shaft motor 12 and meshes with the rack 15. During operation, the dual-shaft motor 12 drives the gear 14 to rotate, causing the rack 15 to rise and fall, thereby raising and lowering the lifting ring 13. Additionally, an insulating rope 3, which is attached to the conductor 2, passes through the lifting ring 13.

[0032] The locking assembly of this utility model includes a swing arm 16 with transmission teeth and a second gear 17. The second gear 17 is connected to a dual-shaft motor 12 and meshes with the transmission teeth. During operation, the dual-shaft motor 12 drives the second gear 17 to rotate, thereby driving the swing arm 16 to rotate via the transmission teeth. The dual-shaft motor 12 simultaneously drives the lifting ring 13 to rise and the swing arm 16 to rotate, causing the lifting ring 13 to raise the insulating rope 3 and the swing arm 16 and the traveling wheel 5 to form a closed area around the conductor 2. The dual-shaft motor 12 simultaneously drives the lifting ring 13 to descend and the swing arm 16 to rotate back to its original position, causing the insulating rope 3 to descend and the swing arm 16 to open. After the insulating rope 3 descends, it facilitates the subsequent detachment of the sealing net device from the conductor 2.

[0033] During implementation, the working steps of the automatic online transmission line grid sealing mechanism are as follows:

[0034] (1) Hang the insulating net on each sealing device 1.

[0035] (2) Use a drone to pull the insulating rope 3 so that it can pass around the overhead wire 2 to form a climbing track. In this embodiment, a total of six insulating ropes 3 need to be hung on the two parallel wires 2.

[0036] (3) After passing the six insulating ropes 3 through the lifting rings 13 of each sealing device 1, insert the two ends of the insulating ropes 3 into the two winches 6 of the sealing device 1. Start the winch drive 10, and the winch drive 10 drives the winch 6 to rotate so that the sealing device 1 climbs along the insulating ropes 3 to the position of the conductor 2.

[0037] (4) During the ascent of the sealing device 1, the guide 11 enables the sealing device 1 to be automatically attached to the conductor 2. Then, the dual-head shaft motor 12 simultaneously drives the lifting ring 13 to rise and the swing arm 16 to rotate, thereby locking the conductor 2 with the buckle and ensuring that the sealing device 1 is firmly attached to the conductor 2. At the same time, the lifting ring 13 raises the insulating rope 3 to prevent the insulating rope 3 from interfering with the conductor 2 during subsequent movement.

[0038] (5) Control the walking drive 9 of each sealing device 1 to drive the walking wheel 5 to rotate, so that each sealing device 1 walks and moves on the conductor 2, and gradually unfolds the insulating net hanging on each sealing device 1.

[0039] (6) Control the position of each sealing device 1 on the conductor 2 by controlling the walking drive component 9 to ensure that the insulating net completely covers the area to be sealed.

[0040] (7) Control the lifting ring 13 to descend, and lower the insulating rope 3 to the conductor 2; at the same time, control the swing arm 16 to rotate and reset to open, so as to facilitate subsequent lowering of the line.

[0041] (8) Control the winch drive 10 to reverse, the sealing net device 1 descends through the insulating rope 3, and under the guidance of the guide 11, the sealing net device 1 separates from the wire 2, completes the unloading, and the insulating net is retrieved.

[0042] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
