Description

Technical Field
The invention relates to a self-resetting energy-consuming inhaul cable supporting device based on a pre-pressed disc spring, and belongs to the field of engineering shock absorption equipment.
Background
The traditional supporting member for engineering earthquake resistance usually generates larger unrecoverable deformation after strong earthquake, thereby not only threatening the safety of the structure, but also causing huge economic cost and repair time cost for the repair of the structure after earthquake. The self-resetting support has a self-recovery function after a strong earthquake and accords with the development direction of the support member.
From the stress characteristic of the supporting member, the existing self-resetting support generally adopts a stiff support form, and the stability problem is more prominent, so that a larger cross-sectional area is often required to be selected, the material consumption is large, and the structural response is strong. And the inhaul cable support does not have the problem of pressure instability, so that a high-strength material can be adopted, the cross-sectional area and the rigidity of the support are reduced, and the seismic response of the support structure is further alleviated.
From the material selection of the self-resetting system, the existing self-resetting support mostly adopts prestressed composite rib materials, and has the following defects: the prestress is difficult to apply, and the tension control stress is difficult to accurately control; the prestressed tendon material has high performance requirement and higher price; the prestressed tendon anchoring process has high requirements; anchorages often require special designs and the like. Compared with the prior art, the self-resetting system adopting the disc spring not only can greatly simplify the application process of the pre-pressure, but also can realize the effective maintenance of the pre-pressure without special anchoring measures.
In addition, the friction force of the existing self-resetting support friction system is difficult to control accurately.
Therefore, the invention aims to provide a self-resetting energy-consuming inhaul cable supporting device based on a pre-pressed disc spring, which realizes the self-resetting function of the support after an earthquake by utilizing the pre-pressed disc spring and has the advantages of convenient construction and stable and reliable pre-pressure; the high-strength steel cable is adopted to replace a stiff supporting form, so that the tensile property of the material is fully exerted, the material is saved, and the seismic response of the supporting structure is reduced; and a special friction structure is adopted, so that the accuracy of applying the friction force is improved.

The self-resetting energy consumption principle of the invention is as follows: the ear plate and the high-strength steel cable are respectively connected with a structure. When the structure is subjected to a lateral seismic action, a tensile force P will be generated within the invention.
When the tension P is small, one end of the high-strength steel cable is connected with the sliding frame, and the sliding frame is under the combined action of the pre-pressure of the disc spring and the friction force of the friction mechanism, so that the sliding frame cannot slide and keeps static. At this time, the energy consuming mechanism does not work, and the friction mechanism does not work.
When the tension P is increased to overcome the combined action of the pre-pressure of the disc spring (11) and the friction force of the friction mechanism, the sliding frame slides, the rigidity of the device is expressed as the rigidity of the high-strength steel cable, the energy dissipation mechanism and the reset mechanism which are connected in series, and compared with the rigidity of the high-strength steel cable, the rigidity is reduced, so that the earthquake response of the structure can be reduced. Meanwhile, the sliding frame and the friction plate move relative to the steel clamping plate, so that the friction mechanism is excited to work, the energy input into the device by the earthquake can be dissipated through solid friction, and the safety of a structure is further ensured.
When the earthquake occurs, i.e. P begins to unload, the sliding frame moves to the initial position under the restoring force provided by the resetting mechanism. The sliding frame and the friction plate move relatively to the steel clamping plate, so that the friction mechanism is excited to work, the energy input into the device in the earthquake can be dissipated through solid friction, and the safety of a structure is further ensured. Finally, the device of the invention completely returns to the initial state under the action of the reset mechanism, thus realizing the effect of self-reset.
Through the self-resetting support, the self-resetting support has a self-resetting function after a strong earthquake, and is the development direction of the support member. The cable support has no problem of buckling under pressure, so that the strength of the material can be fully utilized, the cross section area of the support is reduced, and the cable support has the function of relieving the earthquake response of the structure. The self-resetting support and the cable support are combined, so that the advantages of two support forms can be fully exerted, the advantages are made up for the deficiencies, and the self-resetting support and the cable support have good engineering application prospects. The invention mainly comprises the following components: the energy-saving device comprises a connecting piece, a bottom plate, an upper cover plate, a reset mechanism, an energy dissipation mechanism, a limiting plate and a high-strength steel cable. The invention has good application prospect in earthquake-proof defense areas.
