Middle tension adjusting device for pretightening force control for facilities

Abstract

The invention discloses a middle tension adjusting device for pretightening force control for facilities. The middle tension adjusting device comprises a main hollow shell. The middle tension adjusting device utilizes a thread structure and an air pressure to work together, thereby playing an effective protective role and having strong control for pretightening force. When the thread structure isunder stress, the middle tension adjusting device has stable limiting. Meanwhile, when high-pressure gas is under stress, the middle tension adjusting device has the characteristics of buffering effect and large bearing range. Therefore, the device has the characteristics of long service life and strong resistance to pressure. Moreover, the device is provided with a thread stress length adjustingcontrol mechanism. The thread stress length adjusting control mechanism can adjust the actual length of the device through the thread structure, thereby playing a limiting role. In addition, the device is provided with a universal connection and rotary limiting fixing mechanism. The universal connection and rotary limiting fixing mechanism can realize a multi-angle rotation effect after connectingtwo components, thereby adapting to different angles of connection. Moreover, the device has strong compression resistance. In addition, the device is provided with a steel wire rope connection fixing mechanism which can be effectively connected with the end part of a steel wire rope.

Description

technical field [0001] The invention relates to the technical field of facility pretightening force, in particular to a central tension adjustment device for facility pretightening force regulation. Background technique [0002] At present, in some places, in order to prevent tilting of vertically installed facilities, a pre-tightening force control device is installed on the opposite side of the facility to the side prone to tilting, which is used to pull the top of the facility, thereby reducing the seriousness of tilting However, the existing facility preload control device only adjusts the tension of the wire rope through the threaded structure and the steel wire rope, and then controls the maximum control preload of the device, which not only has poor control effect, but also has relatively large limitations. Contents of the invention [0003] The object of the present invention is to provide a middle tension adjustment device for adjusting and controlling the pre-tig...
