[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 A hoisting device for power transmission line maintenance includes a base plate 1, a guardrail 2 fixedly installed on the top of the base plate 1, a lifting ring 3 fixedly installed on the top of the guardrail 2, a lifting device 4 provided on the outside of the base plate 1, the lifting ring 3 and the lifting device 4 being connected by a lifting chain 5, an extension structure 6 provided inside the base plate 1, and an auxiliary fixing structure 7 provided on the outside of the base plate 1.

[0025] The extension structure 6 includes an electric slide rail 601, which is fixedly installed inside the base plate 1. A slider 602 is provided on the outer surface of the electric slide rail 601. A hinge seat 603 is fixedly installed on the outer surface of the slider 602. A telescopic rod 604 is hinged inside the hinge seat 603. An extension plate 605 is movably connected inside the base plate 1. A baffle 606 is fixedly installed on the outer surface of the extension plate 605. A stop bar 607 is fixedly installed on the outer surface of the baffle 606. A insertion hole 608 is opened inside the stop bar 607.

[0026] Furthermore, the auxiliary fixing structure 7 includes a T-shaped rod 701, which is movably connected inside the guardrail 2. A first spring 702 is fixedly installed on the inner top wall of the T-shaped rod 701, and a movable extrusion block 703 is fixedly installed at the bottom of the first spring 702. A rack 704 is fixedly installed on the inner bottom wall of the guardrail 2, and an installation box 705 is fixedly installed on the outer surface of the guardrail 2. A second spring 706 is fixedly installed inside the installation box 705, and a movable plate 707 is fixedly installed at the end of the second spring 706. A plug-in rod 708 is fixedly installed on the outer surface of the movable plate 707.

[0027] Specifically, such as Figure 3 and Figure 4 As shown, when a power transmission line maintenance procedure is required, the internal space of the device is adjusted according to the number of instruments to be carried and the number of maintenance personnel. Pulling the U-shaped lever causes the plug rod 708 to be taken out from the plug hole 608 of the stop bar 607. Then, the electric slide rail 601 is opened to move the slider 602. The movement of the slider 602 can drive the four hinge seats 603 and the four telescopic rods 604 to move initially. This, in conjunction with the other four hinge seats 603, drives the two extension plates 605 to move outward from the base plate 1. During the outward movement of the extension plates 605, the stop bar 607 and the T-shaped rod 701 will move outward, thereby increasing or adjusting the internal space of the device.

[0028] Specifically, such as Figure 3As shown, during the movement of the stop lever 607 and the T-shaped lever 701, the T-shaped lever 701 will drive the movable extrusion block 703 to move along the outer surface of the rack 704. During the movement, the movable extrusion block 703 will be briefly retracted into the T-shaped lever 701 by the pressure of the rack 704, and will also press the first spring 702. Then, when the T-shaped lever 701 and the stop lever 607 move to the appropriate position, the movable extrusion block 703 will be pushed out again under the action of the first spring 702, and will cooperate with the rack 704 to initially fix the position of the baffle 606 and the stop lever 607. Then, by releasing the U-shaped pull rod, the movable plate 707 and the plug-in rod 708 will be moved under the action of the second spring 706. The plug-in rod 708 will be sent into the plug-in hole 608 of the stop lever 607 through the movable plate 707, fixing the position of the stop lever 607 again, thereby fixing the position of the baffle 606, and thus fixing the internal space.

[0029] Specifically, such as Figure 1 As shown, the control panel is electrically connected to the internal power-operated equipment of the device. It sends control commands to each component via control signal lines. These signal lines can be analog signal lines such as 4-20mA current signals, digital signal lines such as RS485 communication interfaces, or simple switch signal lines. The control signals issued by the control panel are transmitted to the control units of each component through the signal lines. By operating the control panel, the internal components of the device can be controlled, enabling the start and stop operations of each component. After receiving a start command, the controller sends corresponding control signals to each component to start them. When a stop command is received, a stop signal is sent to stop each component from working. The operating parameters of each component can be set on the control panel interface. These parameter settings are converted into corresponding control signals and sent to the control units of each component, thereby achieving precise adjustment of the operating status of the components. The control panel has a monitoring function for the operating status of each component and can display the operating parameters and status information of each component in real time.

[0030] Specifically, such as Figure 4As shown, the main components of the electric slide rail 601 include a power supply, a motor, a driver, a controller, a transmission mechanism, and the slide rail itself, which consists of a track and a slider 602. Its working principle is as follows: the power supply provides electrical energy to the entire system; the motor, as the power source, is controlled to rotate by the driver under the command of the controller; and the transmission mechanism is responsible for converting the rotational motion of the motor into the linear motion of the slider 602 on the slide rail. Common transmission mechanisms include precision mechanical structures such as worm gears, lead screws, and nuts. During operation, the controller precisely controls the motor's speed, direction, and working time according to a preset program or external signals, thereby driving the slider 602 to slide smoothly and accurately on the track. This motion mode has high precision and stability, meeting the linear motion requirements of various automated equipment and precision machinery. Furthermore, the electric slide rail 601 is equipped with limit devices and safety protection devices to ensure that the slider 602 moves within a specified range and can quickly stop in case of abnormal conditions, thus protecting the safety of the equipment and operators. At the same time, the maintenance and upkeep of the electric slide rail 601 are relatively simple; only regular inspection and lubrication are needed to ensure its long-term stable operation.

[0031] When implementing this procedure, please follow these steps:

[0032] 1) By first setting up the extension structure 6, the internal space of the device can be expanded or adjusted to meet the space requirements of different testing workers or different testing instruments.

[0033] 2) Then, the adjusted equipment space size is fixed by the auxiliary fixing structure 7 to prevent the space size from changing due to external forces during use;

[0034] 3) Open the box door again to place the testing equipment on the base plate 1, and let the maintenance worker stand on the base plate 1. Then connect it to the external crane through the lifting device 4, and with the help of the lifting ring 3 and the lifting chain 5, drive the device to rise and carry out the maintenance process of the overhead power transmission line.

[0035] In summary, this hoisting equipment for power transmission line maintenance, based on actual usage, adjusts the internal space of the device through the setting of the expansion structure 6. After the internal space adjustment or expansion is completed, the expansion structure 6 is fixed by the setting of the auxiliary fixing structure 7, thereby fixing the internal space range. Then, by opening the box door, the maintenance instruments and personnel can be placed on the base plate 1, and connected to the external crane through the setting of the lifting device 4, and then the device is lifted to carry out the power transmission line maintenance procedure, thereby achieving the purpose of facilitating the adjustment of the hoisting equipment space according to usage requirements.
