Description

Technical Field

[0001] This utility model relates to the field of rail suspension device technology, and in particular to an auxiliary rail suspension device for a railcar. Background Technology

[0002] In the laying and maintenance of railway and urban rail transit lines, the hoisting, transportation, and precise positioning of rails are crucial aspects of the construction process. Traditional rail hoisting operations rely heavily on manual labor combined with simple lifting equipment or large cranes, resulting in low automation, low efficiency, and high labor intensity. Especially at construction sites with limited space or complex terrain, large hoisting equipment is difficult to access, leading to slow construction progress.

[0003] Furthermore, some existing track-assisted hoisting devices often have poor structural stability, making them prone to swaying during movement and lifting, affecting the accuracy and safety of the hoisting process. At the same time, during operation, the devices' cables or connecting lines often lack effective management and protection measures, making them susceptible to tangling, dragging abrasion, or even crushing damage. This not only poses safety hazards but also reduces the reliability and lifespan of the equipment. Utility Model Content

At the same time, the end of the support rod away from the base frame is fixedly connected to the top beam, and a load-bearing rod for supporting the weight of the device is provided on the support rod.

[0011] As a further description of the above technical solution:

[0012] The electric walking assembly is connected to a signal line, and the end of the signal line away from the electric walking assembly is connected to a controller for controlling the opening and closing of the electric walking assembly and the winch.
