Gantry crane cable fold-back device

Abstract

The invention discloses a gantry crane cable fold-back device. The gantry crane cable fold-back device comprises a bottom plate, an upper panel and multiple arc-shaped plates; the bottom plate is arranged obliquely; the upper panel is located above the bottom plate and is parallel with the bottom plate; a gantry crane cable penetrates from space between the upper panel and the bottom plate along the inclination direction of the bottom plate; and the multiple arc-shaped plates are respectively arranged at the left side and the right side of the gantry crane. The arc-shaped plates at the left side and the right side of the gantry crane are fixedly arranged between the bottom plate and the upper panel at vertical intervals along an inclination longitudinal direction; a cylindrical vertical direction adjusting part is fixedly arranged at the back end part of the upper panel; the back end part of the upper panel is fixedly arranged at the outer wall of the vertical direction adjusting part; a fixing device is fixedly arranged in front of the bottom plate; and the gantry crane penetrates from the fixing device and is fastened by the fixing device. The gantry crane cable fold-back device is capable of reducing labor intensity of workers, increasing safety coefficient and improving economic benefits.

Description

technical field [0001] The invention belongs to the field of door machines, and in particular relates to a door machine cable return device. Background technique [0002] The loading and unloading of goods at the wharf mainly relies on portal cranes, referred to as portal cranes. The number of door cranes installed at the wharf is generally determined according to the length of the berth, while the position of the door crane during operation is determined by the berth of the operating ship. When the parking position of the door operator does not correspond to the operating cabin, the door operator should move horizontally along the track in the direction of the wharf to reach the operating hatch, commonly known as a sports car. During the running process, the cable of the door operator will be retracted with the movement of the door operator, and will be loosened or tightened, so as to avoid the cable being too loose during the movement of the door operator, causing it to b...

AI Technical Summary

Problems solved by technology

[0003] During the retraction process of the door operator cable, due to the problem of the retraction angle (the minimum cable bending angle is less than 125°), direct friction between the cable and the metal structure of the door operator often occurs, causing the cable insulation skin to be broken, and a large number of cable skins Severe damage, resulting in potential leakage
