Embodiment Construction

[0017] The existing cable force fine-tuning device of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0018] An existing cable force fine-tuning device of the present invention includes a mechanical frame 1 and a miniature jack 4 . When the micro-jack 4 applies an external force along the direction perpendicular to the cable, under the constraint of the arm levers on both sides of the mechanical frame 1, the cable 3 produces a lateral displacement, and its internal cable force will change. The micro-jack 4 can provide a large driving force, thereby realizing the adjustment of a large cable structure and reducing the difficulty of adjustment.

[0019] The mechanical frame 1 is composed of a mechanical rod and two pulley slots 2 . The main body of the mechanical rod is three mechanical rods arranged in a trapezoidal state, including two arms and a cross bar. The arms are connected to the cross bar, and the op...

Abstract

The invention discloses an existing cable force fine adjusting device. The existing cable force fine adjusting device comprises a mechanical frame, pulleys arranged on two ends of the mechanical frame and a micro jack which is arranged in the middle part of the mechanical frame, wherein the mechanical frame is of a bow-shaped structure; and a passage used for a pulling cable to penetrate through is formed between the positions for arranging the pulleys at the two ends and the inner side of the bow-shaped structure. Great pushing force can be provided by the existing cable force fine adjusting device, so that adjusting on large pulling cable structures is realized; adjusting difficulty is lowered; and operation is convenient.

Description

technical field [0001] The invention relates to a cable force adjusting device, in particular to an existing fine-tuning device for cable force. Background technique [0002] In many projects now, there are parts of cable structures. In the actual installation and construction process, the cables often need to be connected to each other. Most of the current projects use manual adjustment of the connection screws at both ends of the cables to adjust the cable force. However, the stay cables in large structures have high cable forces, and the current method is very difficult to operate in this case. [0003] Therefore, a kind of existing cable force fine-tuning device is needed. Contents of the invention [0004] Technical problem: The purpose of this invention is to provide an existing cable force fine-tuning device with large adjustment force, easy operation, and reduced construction difficulty. difficult question. [0005] Technical solution: An existing cable for...
