Description

Technical Field

[0001] This invention relates to the field of cable transportation and laying equipment technology, and in particular to a mobile cable conveying trolley for cable conveying gantry cranes. Background Technology

[0002] Traditional gantry crane cable delivery involves transporting the cable along a channel along the upper surface of the boom, with the delivery range adjusted by the boom's tilt angle. When the boom is too long, the cable delivery radius is often quite large, and even when the boom is shortened, the radius during operation is still greater than the boom length, making it unsuitable for small-tonnage vessels. Even on large-tonnage transport ships, the cable delivery position can only be offset to one side, requiring additional transport vessels or extra manpower and resources to adjust the cable's placement, resulting in significant resource consumption. Furthermore, the traditional gantry crane cable delivery method exposes the cable to friction with the boom, accelerating the wear and tear of the cable insulation. Summary of the Invention

The car baffle 16 can prevent the moving cable assembly 12 and the trolley wheel assembly 6 from running off the track beam 4, and plays a safety protection role.

[0028] Working principle: When cables need to be transported to the transport ship, the cable output from the cable conveyor 11 is sent to the lower right side of the trolley frame 5 via several trolley roller assemblies 7 and onto the transport ship. During the conveying process, if the cable delivery position needs to be adjusted, the motor 902 drives the two drums 904 to rotate synchronously forward or reverse through the reducer 903. This causes the two steel wire ropes 10 wound on the two drums 904 to move the trolley frame 5 left and right along the track beam 4, thereby adjusting the cable delivery position. When it is necessary to unload the cables from the transport ship, the position of the trolley frame 5 is first adjusted according to the ship type. After the position of the trolley frame 5 is adjusted, the cables on the transport ship are sent to the cable conveyor 11 from the lower right side of the trolley frame 5 via several trolley roller assemblies 7, thus completing the unloading of the cables from the transport ship. During the entire movement of the trolley frame, several moving cable support assemblies 12 always provide support for the cables to prevent the cables from sagging due to excessive cable support gaps, which would affect the cable life and cable conveying efficiency.
