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. Background Technology

[0002] Transmission line mesh enclosures are devices used during the construction of transmission lines, especially when crossing areas such as highways, high-speed railways, and important transmission corridors, to build protective barriers to ensure construction safety and line safety.

[0003] The traditional manual method of installing insulating netting involves two workers riding a scaffold to the conductor, each holding one end of the netting and securing it to the conductor. To retrieve the netting, the two workers return along the same route to untangle it. This method presents safety hazards for workers at heights, and the manual installation is inefficient and physically demanding.

[0004] Currently, some methods have emerged that use traveling mechanisms to deliver and deploy insulating nets to designated locations, replacing traditional manual labor. However, due to variations in the distance and height of the netting, the weight of the insulating netting varies accordingly. When this traveling mechanism pulls insulating nets of different weights and travels along overhead transmission lines, the wheels are not always in the same position due to the weight of the netting, making slippage or insufficient traction likely. Furthermore, this method can lead to uneven wear on the wheels of the traveling mechanism, indirectly exacerbating the problem of insufficient traction. Simply increasing the motor's driving force would increase its weight and size, significantly increasing the load on the overhead transmission lines and compromising the safety of the netting installation. Additionally, existing traveling mechanisms suffer from insufficient traction, resulting in slow netting speed and low efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a power transmission line sealing mechanism. This sealing mechanism can monitor the clamping force of the traveling wheel on the conductor in real time and adjust the clamping force. It can not only effectively avoid the problems of slippage of the traction wheel and insufficient traction force, but also lay insulation nets of different weights stably and efficiently, thereby ensuring stable sealing construction.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a power transmission line sealing mesh mechanism, characterized in that: it includes at least two sets of sealing mesh components and an insulating mesh; each set of sealing mesh components includes at least two traction sealing mesh traveling modules that travel on the conductors of the power transmission line; the insulating mesh is hung on each traction sealing mesh traveling module; each traction sealing mesh traveling module includes a traveling wheel assembly with traveling wheels, and the traction sealing mesh traveling module travels on the conductors through the traveling wheels and pulls the insulating mesh to achieve the laying of the insulating mesh;

[0007] The walking wheels are height-adjustable; the walking wheel assembly is equipped with a pressure sensor; during the movement of the conductor, the pressure sensor detects the clamping force of the walking wheels on the conductor in real time and transmits it to the controller. The controller controls the lifting and lowering of the walking wheel assembly, or controls and adjusts the output torque of the driving walking wheels, so as to adjust the appropriate clamping force of the traction sealing module on the conductor.

[0008] In the above-described scheme, the transmission line sealing mechanism of this invention can detect the clamping force of the upper and lower traveling wheels on the conductor in real time through pressure sensors, and adjust the clamping force through a controller. This not only effectively avoids slippage of the upper and lower traveling wheels and insufficient traction, but also enables stable traction and laying of insulating nets of different weights, thereby ensuring stable sealing construction. Furthermore, increasing the traction force of this transmission line sealing mechanism can improve the sealing speed and efficiency.

[0009] Each set of enclosure components is installed in parallel and hung on the conductor of the transmission line.

[0010] The traveling wheel assembly includes an upper traveling wheel assembly with an upper traveling wheel and a lower traveling wheel assembly with a lower traveling wheel. The traction sealing net traveling module travels and pulls on the conductor by clamping the upper and lower traveling wheels. Both the upper and lower traveling wheel assemblies are equipped with pressure sensors, and both the upper and lower traveling wheels are liftable structures.

[0011] The traction sealing net walking module also includes a plate, a support part connected to the plate, and an electrical control box equipped with a controller; the upper walking wheel assembly is set on the plate, the lower walking wheel assembly is set on the support part, and the upper walking wheel assembly and the lower walking wheel assembly serve as a clamping station for the wire; the electrical control box is set on the plate and is connected to the upper walking wheel assembly and the lower walking wheel assembly respectively.

[0012] The traction sealing mesh walking module also includes hooks for hanging insulating mesh; the hooks are set on both sides of the plate.

[0013] The upper and lower traveling wheel assemblies have the same structure but are staggered.

[0014] Both the upper and lower traveling wheel assemblies further include a traveling wheel seat, a drive module, a transmission component, a lifting plate, and a lifting drive module. The drive module is mounted on the traveling wheel seat and connected to the upper / lower traveling wheel to drive its rotation. The lifting plate is connected to both the traveling wheel seat and the transmission component, and a pressure sensor is mounted on the traveling wheel seat. The lifting drive module is connected to the lifting plate via the transmission component to drive the lifting plate to rise and fall, thereby raising and lowering the upper / lower traveling wheel on the traveling wheel seat.

[0015] The lifting drive module includes a lifting motor and a synchronous pulley assembly; the synchronous pulley assembly is connected to the transmission component, and the lifting motor is connected to the synchronous pulley assembly, so as to drive the transmission component to move and drive the lifting plate to rise and fall.

[0016] The transmission component includes a lead screw and a nut; the lead screw is connected to a synchronous pulley assembly, and the nut is connected to a lifting plate; the nut is threadedly connected to the lead screw; the lifting motor drives the lead screw to rotate through the synchronous pulley assembly, causing the nut to rise and fall, thereby driving the lifting plate to rise and fall.

[0017] Both the upper and lower traveling wheel assemblies include a linear guide rail and a fixed plate; the fixed plate is connected to the plate, the linear guide rail is mounted on the fixed plate, and the lifting plate can move up and down along the linear guide rail. This design improves the stability of the upper / lower traveling wheel lifting.

[0018] The features of this utility model's power transmission line sealing mechanism are as follows:

[0019] 1. Each pressure sensor continuously monitors the clamping force of the upper and lower traveling wheels on the guide wire and sends the data back to the control box. The control box adjusts the forward and reverse output torque of each drive module, or regulates the raising and lowering of the upper and lower traveling wheels, based on set values ​​to ensure the clamping force of the upper and lower traveling wheels matches the set values. This independent control mechanism effectively avoids problems such as wheel slippage, insufficient traction, and uneven wear.

[0020] 2. The transmission line sealing mesh mechanism can hang insulating mesh of different weights and operate stably. By adjusting the clamping force in real time, it ensures traction stability under complex working conditions, avoids excessive weight of the device due to increased motor drive force, and ensures the safety and ease of operation of the mechanism on overhead lines.

[0021] 3. During the movement of the traction-operated mesh sealing module, a cycle check and adjustment are performed every 0.2 seconds to ensure the real-time performance and accuracy of the clamping force. The pressure signal is processed and regulated via the electrical control box to ensure the stability of the entire mesh sealing operation.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects: The transmission line sealing mesh mechanism of the present invention can monitor the clamping force of the traveling wheel on the conductor in real time and adjust the clamping force, which can not only effectively avoid the problems of slippage of the traction wheel and insufficient traction force, but also lay insulation mesh of different weights stably and efficiently, thereby ensuring stable sealing mesh construction.
