AI Technical Summary
In the existing door-mounted machine room rope outlet closure device, the aging of soft rubber leads to poor rebound elasticity and poor sealing effect. At the same time, the contact between the wire rope and the rubber leads to wear, affecting the sealing effect.
A guide mechanism consisting of three sets of support rods is designed to actively squeeze the upper end of the rubber skin by rolling to ensure that the sealing effect does not depend on the elasticity of the rubber, and reduce the wear of the rubber skin through the wire rope conduit.
Even if the rubber ages, it will not directly affect the sealing effect, and the wear between the wire rope and the rubber is reduced through the conduit, improving the long-term stability of the sealing device.

Description
Technical Field
[0001] The utility model relates to a closing device, in particular to a closing device for the rope outlet of the engine room of a portal crane, belonging to the technical field of hoisting equipment. Background Art
[0002] At present, the closing of the rope outlet of the engine room of a single-boom portal crane adopts two cross-arranged soft rubbers. The upper ends of the two soft rubbers are cross-closed to form a closure. The steel wire rope directly passes through the closed part at the upper ends of the two soft rubbers, and the two soft rubbers are automatically closed by the resilience and self-weight. However, it is found in actual use that after a period of use, the aging of the soft rubber will cause the resilience of the rubber itself to become poor, resulting in a poor closing effect. In addition, the steel wire rope is in direct contact with the soft rubber, and the up-and-down and lateral movements of the steel wire rope will cause wear on the contact part of the soft rubber, further affecting the closing effect of the rope outlet.
