Problems solved by technology

The pressure block type rope guide is similar to the spiral groove rope guide, which is also sliding friction. The pressure block of the rope guide has long-term friction with the reel, which is easy to cause wear and tear. The rope pressure block needs to be manufactured separately, and the ring body of the rope guide needs to be processed. , the cost is relatively high

Abstract

The invention discloses a crane winding drum rope-arranging device. The crane winding drum rope-arranging device comprises a front semiring and a rear semiring which are connected with each other through a connecting sheet, wherein a rope-arranging opening is formed in the front semiring; a plurality of metras screws are arranged on the inner sides of both the front semiring and the rear semiring; each metras screw comprises a screw body; a groove is formed in the middle of each screw body; a spring is mounted in each groove; a steel ball is arranged at the end, close to the end opening of the groove, of the spring. The crane winding drum rope-arranging device can convert the friction relationship between the rope-arranging device and the winding drum from sliding friction to rolling friction, so that the friction between the rope-arranging device and the winding drum is effectively reduced, the abrasion of the rope-arranging device and / or the winding drum is reduced; the metras screws can extend or retract automatically under the pressure of the winding drum, so that a gap cannot be formed between the rope-arranging device and the winding drum, and vibration or noise caused by the gap between the rope-arranging device and / or the winding drum is avoided.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane drum rope arrangement device. Background technique [0002] At present, most cranes use steel wire ropes to lift or transfer goods. Therefore, almost all crane drums have rope arrangement devices. At present, the existing rope arrangement devices include spiral groove rope guides and briquetting type rope guides. Among them, the spiral groove rope guide adopts the method of cooperating with the reel spiral groove to arrange the rope, which is the current domestic electric hoist routine practice. disconnected. Due to long-term friction between the rope guide and the reel, there will be a gap between the helical groove and the helical teeth, the rope guide will easily shake, and there will be noise for a long time. At the same time, the rope guide cannot automatically adjust this gap. The pressure block type rope guide is similar to the spiral groove rope guide, which is a...
