Description

Technical Field

[0001] The present invention relates to the technical field of fixed pulling ropes, in particular to a universal equipment railway transportation pulling rope. Background Art

[0002] In the modern logistics and national defense transportation system, the railway transportation of general-purpose equipment (including engineering machinery, large electromechanical equipment, and military equipment) has become a key mode of cross-regional long-distance transportation due to its advantages such as large transportation volume, low cost, and little impact from climate. This type of equipment is often characterized by large size, concentrated weight, and a high center of gravity. During railway transportation, it will generate longitudinal, lateral, and vertical impact and inertial forces due to train starting and braking, track undulations, and curve turns.

[0003] Existing equipment railway transport binding reinforcements are gradually unable to meet the needs of modern general equipment transportation. If the fixing measures fail, it may cause equipment displacement, collision or even overturning, which will not only cause equipment damage, but may also cause train operation accidents. Therefore, the reliability requirements of fixed connectors are extremely high.

[0004] Existing traction ropes, such as CN2615010Y, disclose a lashing and reinforcement device for transporting wheeled heavy equipment. The device consists of a fastener and a wheel chock. The fastener is used to tie the wheeled vehicle to a railway flatbed, and the wheel chock is used to block the wheels. The fastener is a chain-type device, comprising an Ω-shaped hook or a steel wire rope sling connected to a double hook, connected to an adjuster via a spring and a locking sleeve. The adjuster utilizes an adjustable double-screw structure that cooperates with a locker, which is engaged with the chain to adjust the lashing length. The wheel chock utilizes a folding steel structure, comprising a shield plate hinged to upper and lower support rods, which are positioned by a locking hook and a lock buckle. The use of this device shortens loading and unloading time during railway transportation, reduces labor intensity, and significantly improves safety, which will promote the development of civil railway transportation. Existing lashing and reinforcement devices have a single tensioning and adjusting chain, which can only be used to secure a predetermined fixed point, and one end requires a T-hook hook or a support slot hook for fixation.

[0005] Therefore, those skilled in the art are in urgent need of providing a universal equipment railway transport pull rope with multiple adjustment methods for tensioning adjustment, which can be used to fix any fixed point and can be optionally fixed with a T-hook or a support groove.
