Description

Technical Field

[0001] This utility model relates to the field of track hoisting, and in particular to a track hoisting tool and track hoisting device. Background Technology

[0002] Currently, there are two types of rail lifting devices. One type uses a mechanical clamping mechanism, where the lifting device slides down under gravity, the clamping mechanism wraps around the rail, and when the lifting device is lifted, the clamping mechanism locks the rail head for hoisting. The other type is a simple lifting structure, which typically uses a pin-shaft connection structure to clamp the rail head for hoisting; or it uses a rail-mounted lifting device that matches the rail cross-section, installed from the end of the rail, and then moved to the lifting point for hoisting.

[0003] However, the rail-mounted lifting devices using current mechanical clamping mechanisms generally have a large lifting volume, making them unsuitable for applications with limited clearance on vehicle-mounted cantilever cranes; moreover, there is a risk of disengagement during lifting. For simple lifting structures, pin-connection structures are typically used, resulting in poor overall structural integrity, concentrated stress on the pins, and a safety hazard of metal breakage around the pins; furthermore, the rail-mounted lifting devices are cumbersome to assemble and disassemble, have poor adaptability to vertical rail lifting conditions, and are prone to scratching the rails.
