Description

Technical Field

[0001] This utility model relates to a lifting device, specifically an electric mobile cable lifting device. Background Technology

[0002] With the development of urban rail transit, elevated cables are exposed to the outdoor environment for extended periods, leading to frequent cable detachment failures due to weather, temperature, and aging. Taking Shanghai Metro Line 3 as an example, its elevated sections contain a large total length and variety of 35kV and 10kV ring network AC cables, and in 2023, cable detachment accounted for a significant proportion of all failures. As the service life increases, cable aging problems intensify, leading to a continuous increase in the workload of specialized cable maintenance.

[0003] Currently, cable maintenance mainly relies on manual operation, which has the following significant drawbacks: low efficiency and high risk due to manual lifting; and the large cross-section and heavy weight of medium and high voltage cables (e.g., 150mm²). 2 The three-phase cable weighs up to 50kg, requiring at least 2-3 maintenance personnel to lift it. In high-altitude operations, manual lifting easily leads to muscle strain or falls, and precise control of the lifting height is difficult. Existing equipment lacks adaptability: Existing simple lifting equipment has significant limitations: poor portability (lacking mobile design, making flexible transport in narrow spaces); low safety (unstable mechanical structure, easily causing scratch damage to the cable insulation during operation); limited functionality (unable to adapt to different working conditions (such as single cable maintenance, simultaneous lifting at both ends of the support, anti-fall requirements, etc.); and weak environmental adaptability (lacking a waterproof power system, unable to operate in rainy weather, affecting maintenance schedules).

[0004] These defects lead to low cable repair efficiency and pose a risk of secondary damage. Therefore, there is an urgent need for a mobile, electrically operated, multi-scenario adaptable specialized lifting device to improve the safety and efficiency of cable maintenance. Utility Model Content

The motor drives the lifting rod accessories to rise and fall through a transmission steel wire rope. The lifting rod accessories include at least one of the following: typical cable lifting rod accessories suitable for lifting cables that have detached from supports at the same height; accessories suitable for lifting both ends of cable supports; and anti-detachment lifting accessories suitable for preventing cables from detaching during long-term lifting, to adapt to different cable lifting conditions. The control device is electrically connected to the motor and the battery pack and includes a jog button for controlling the lifting and a power stop button.

[0007] In one embodiment, the caster wheel is provided with a mechanical locking mechanism.

[0008] In one embodiment, the variable speed DC motor has a rated power of 200W and a rated voltage of 24V.

[0012] In one embodiment, the system further includes a power supply and control box integrating a battery pack and control devices, wherein the housing of the power supply and control box is a sealed and waterproof structure.

[0013] In one embodiment, the lifting height of the lifting mechanism is in the range of 400mm-1800mm, and the lifting speed can be adjusted to 5mm / s-15mm / s by a control device.

[0014] In one embodiment, the lifting rod accessory further includes a single cable lifting accessory, which can be fitted onto a typical cable lifting rod accessory for independent lifting and maintenance of a single cable in a multi-phase cable.

[0015] In one embodiment, the lifting rod accessory further includes a height-increasing connecting rod accessory, the length of which is 300mm-800mm, used to improve the adaptability of the lifting height during underground cable maintenance.

[0016] This utility model has the following beneficial effects:
