Problems solved by technology

Purely manual work is not only difficult to control the pre-tightening force but also damages personnel and products. Therefore, it is necessary to use a manual adjustment device to apply tension to the wire rope to a specific value, and close the wire rope to form a complete wire rope lock while maintaining the tension value. ring

Embodiment Construction

[0028] The present invention will be further elaborated below in conjunction with embodiment.

[0029] The invention is a manual adjustment device for pre-tightening the tension of a locking ring. The device includes a rope clamping module and a tension adjustment module. The rope clamping module is used for clamping both ends of the rope; the tension adjustment module is used for Provides locking ring preload.

[0030] The rope clamping module includes a first rope positioning block 1, a second rope positioning block 5, a first locking ring collar 6-1, a second locking ring collar 6-2, a first stop screw 8-1, The second limit screw 8-2, wherein, the first rope positioning block 1 and the second rope positioning block 5 have left-right symmetrical structures.

[0031] The first rope positioning block 1 and the second rope positioning block 5 are provided with a boss, and the boss is provided with a groove for the entry and exit of the wire rope. The first locking ring collar ...

Abstract

The invention relates to a manual adjustment device for pre-tightening locking ring tension. The device uses a pre-tightening force adjustment rod as the core adjustment part, and connects the sliding rod and the left and right screw rods to the guide blocks on both sides. The internal space utilization rate is high, the layout is compact and the volume is small. The manual tightening part of the adjusting rod has a square prism structure, which is convenient for operators to perform tightening operations with tools such as pliers. When adjusting the pre-tightening force, the two ends of the locking ring have been fixed by the device itself, without the cooperation of multiple people, which improves the convenience and efficiency of the operation.

Description

technical field [0001] The invention is applied to spacecraft mechanism products and can adjust the tension of ropes, and in particular relates to a manual adjustment device for tension pre-tightening of closed rope loops, belonging to the technical field of precision assembly and adjustment of space expandable mechanisms. Background technique [0002] At present, most spacecraft products use solar wings with rigid substrates as the energy supply system. During the stretching and retracting movement of the solar wings, a linkage device is used between large components such as solar panels to ensure the synchronization of the movement. The linkage device is composed of a hinge linkage wheel, a locking ring (linkage wire rope), and a bracket. Its main function is to ensure that the deployment movement of the solar wing is simplified to a single-degree-of-freedom movement during the deployment process, so that the deployment positions of the solar panels and the connecting fram...
