Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to an electric retractable machine. Background Art

[0002] Electric hanging baskets, elevators or other lifting equipment need to hang long wire ropes or cables during operation. These wire ropes need to be laid or lifted manually before and after construction, which is very inefficient. The longer the wire ropes or cables, the heavier they are, making it more difficult or even impossible to lay or lift them manually. In addition, there are certain safety hazards in manually lifting or lowering wires. After searching, the Chinese patent with publication number CN208980230U discloses an electric retractor. When in use, the U-shaped channel iron of the installation channel frame is fixedly connected to the frame tube of the electric hanging basket or other lifting equipment, and can also be connected to a separate supporting square tube. When the wire is lifted, the wire is bypassed from the bottom of the guide wheel 7, then bypassed the upper half of the trapezoidal groove of the groove wheel 5 upward, and then passed through the trapezoidal groove between the pressure wheel 8 and the groove wheel 5 downward. During operation, the swing rod 9 is manually pulled outward to make the pressure wheel leave the groove wheel 5 to facilitate the passage of the wire. After the wire passes between the pressure wheel 8 and the groove wheel 5, the swing rod 9 is released, and the boss 14 of the pressure wheel 8 is used to resist the wire, so that the wire is tightly surrounded in the trapezoidal groove of the groove wheel 5. Start the brake motor 3 to drive the groove wheel 5 to rotate, and the lifting of the wire can be achieved. When the wire is lowered, the wire is first passed through the guide groove 15, then passed through the pressure wheel 8, passed upward around the groove wheel 5, and then passed through the guide wheel 7. The motor 3 is started to reverse, and the wire can be lowered. The brake motor itself has a braking function, which can stop the wire at any height. However, since impurities are easily adhered to wires such as wire ropes or cables outdoors, it is not convenient to clean the wire ropes or cables. For this reason, an electric retractor is designed to facilitate cleaning of wire ropes or cables, improve stability during reeling, and facilitate adjustment of the cleaning depth.
