Mobile drum type automatic-tensioning electric freight winch

Abstract

The invention belongs to the field of winches and relates to a mobile drum type automatic-tensioning electric freight winch. The mobile drum type automatic-tensioning electric freight winch comprisesa drum component, a power transmission component, a tensioning mechanism and a shell. The winch has the advantages that the drum of the winch moves in a reciprocating manner and the position of a cable is fixed, fixed-point cable discharge is achieved, an extra cable discharge device is not needed, and the cable swing problem is solved; due to the fact that the extra cable discharge device is notneeded, the winch is compact in structure and low in space occupation.

Description

technical field [0001] The invention belongs to the field of winches and relates to a moving drum type automatic tensioning electric freight winch. Background technique [0002] At present, most of the winches used in the freight system of large-scale transport aircraft are swinging rope winches. This winch is equipped with a rope puller and a rope pressing mechanism; the rope puller moves with the position of the cable on the drum to ensure that the cable is evenly wound on the drum. The rope pressing mechanism ensures that the rope that has been wound on the drum will not become loose due to its own elastic force. [0003] However, there are two problems in this form of winch in use. One is that the cable will swing left and right following the rope puller, and the amplitude of the swing depends on the length of the drum. The longer the drum, the greater the swing range. It will lead to the instability of the goods and the instability of the force. The second is that the...

Problems solved by technology

[0003] However, there are two problems in this form of winch in use. One is that the cable will swing left and right following the rope puller, and the amplitude of the swing depends on the length of the drum. The longer the drum, the greater the swing range. It will lead to the instability of the goods and the instability of the force

The second is that the effect of the rope pressing mechanism is not ideal. The rope pressing mechanism presses the pressure roller on the surface of the drum through the torsion spring. When the cable is wound on the drum, it is pressed on the surface of the drum by the pressure roller. After the coil is completed, the pressure roller is lifted up by the already wound rope loop, and the cable that is then wound on the drum cannot be reliably compressed by the pressure roller, and there is a risk of loosening

However, this solution greatly increases the space and weight occupied by the winch, and does not fundamentally solve the problem of cable swing
