Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a FAST cable-driven traction wire rope drum-lifting multi-directional mobile platform. Background Art

[0002] The FAST cable drive mechanism consists of six sets of drive mechanisms, a machine room (including an electrical room), a tower bottom guide pulley, a tower top guide pulley, traction wire ropes and wire rope anchoring devices, a cable entry mechanism, installation and maintenance equipment, detection and safety protection devices, electrical equipment and electrical control systems.

[0003] The cable drive mechanism is mainly driven by the drive mechanism installed in the machine room at the bottom of the tower, and the dragging traction wire rope is driven by the drive mechanism. One end of the traction wire rope is fixed to the traction wire rope drum group of the drive mechanism, and the wire rope is led to the top of the tower through the guide pulley at the bottom of the tower and the guide pulley at the top of the tower, and connected to the feed cabin connection support through the wire rope anchoring device.

[0004] The cable drive mechanism drives the traction wire rope through the driving mechanism, thereby driving the feed cabin.

[0005] The traction wire rope drum group is installed in the machine room. The frame of the machine room is welded with steel sections and has electromagnetic shielding function. It is extremely strong and has a small area. As a result, if large equipment in the machine room (including reducers, drum groups, etc.) needs to be maintained, the room body can only be partially dismantled first to meet the maintenance conditions (including separation of the reducer and the drum group, etc.). After the maintenance is completed, the room body needs to be restored. The thick restored room body is very likely to lose part of the electromagnetic shielding effect, which will affect the later observations of the telescope. In addition, the drum group weighs 15 tons, so it is very difficult to move the drum or adjust the drum displacement.

[0006] Therefore, how to achieve high-precision movement of the reel group without dismantling the machine room and making full use of the existing space in the machine room becomes the key to maintenance work.

[0007] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
