Description
Technical Field
The utility model relates to a shock insulation shock attenuation technical field, in particular to friction slides from ball-type shock insulation steel support device of restoring to throne.
Background
The existing shock insulation device mainly comprises a rubber shock insulation support, a swinging shock insulation support and friction sliding shock insulation. Wherein rubber shock insulation support can produce certain residual deformation when receiving earthquake effect, sways the risk that shock insulation support can produce toppling when can not in time reseing because of can producing too big range of swaying when the earthquake takes place, and the shock insulation that slides in the friction can make in the earthquake in-process produce very big displacement between superstructure and basis. In order to improve the shock insulation capability of the support, a simple, convenient, feasible, economical and effective shock insulation technology is one of the main approaches, and a novel simple energy dissipation and shock insulation device is designed aiming at the defects of the shock insulation support so as to meet the requirements of reducing deformation and displacement, so that the technical problem which needs to be solved by technical personnel in the field is solved.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a friction sliding is from ball-type shock insulation steel support device who restores to the throne can improve the initial rigidity of structural system, can reach the effect that in time restores to the throne after shaking simultaneously.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a friction slip is from ball-type shock insulation steel support device that restores to throne, includes U shaped steel board 1, U shaped steel board 1 sets up from top to bottom relatively, forms annular cavity in the middle of, is located U shaped steel board 1's U type recess and is provided with tumbler formula steel ball 2, tumbler formula steel ball 2 is connected upper and lower two parts's U shaped steel board 1 respectively through drawknot SMA memory alloy silk 3, and the U type tip of U shaped steel board 1 of upper and lower side passes through mild steel attenuator 4 and links to each other.
The upper part of the tumbler type steel ball 2 is hollow, and the lower part of the tumbler type steel ball is filled with the small steel ball 5 to form a friction sliding shock insulation support with a light upper part and a heavy lower part.
The SMA memory alloy wire 3 is welded with the U-shaped steel plate 1.
The utility model has the advantages that:
the upper part of the friction sliding support with a light upper part and a heavy lower part is hollow, the lower part is filled with the small steel ball 5 to form a tumbler structure, when the steel ball 2 is in balance in a vertical state, the distance between the gravity center and a contact point is minimum, namely the gravity center is lowest, and after the steel ball deviates from a balance position, the gravity center is always raised. Therefore, the balance of this state is stable, so the steel ball 2 does not fall regardless of the swing.
Meanwhile, the composite SMA memory alloy wire 3 also improves the initial rigidity of the structural system by utilizing the super-elasticity performance of the composite SMA memory alloy wire, and can achieve the effect of timely resetting after an earthquake. The soft steel damper 4 plays a role of connecting the upper U-shaped steel plate 1 and the lower U-shaped steel plate 1, and simultaneously dissipates earthquake input energy by means of plastic deformation of the steel plates after yielding to form a complete energy dissipation and shock insulation system, so that energy brought by an earthquake can be better consumed. The purpose of using steel is to overcome the residual deformation generated during earthquake action.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: the utility model provides a friction slip is from ball-type shock insulation steel support device of restoring to throne, includes: the upper part and the lower part of the U-shaped steel plate 1 are provided with a tumbler type steel ball 2 in a U-shaped groove of the U-shaped steel plate 1, the upper part of the tumbler type steel ball 2 is hollow, the lower part of the tumbler type steel ball 2 is filled with a small steel ball 5 to form a friction sliding shock insulation support with a light upper part and a heavy lower part, an SMA memory alloy wire 3 is pulled up and connected with the upper part and the lower part of the U-shaped steel plate 1, the upper part and the lower part of the U-shaped steel plate 1 are connected by a soft steel damper 4, and the soft steel damper 4 plays a role in connecting the upper part and the lower part of the U-shaped steel plate 1 and simultaneously dissipates earthquake input energy by means of.
The steel plate 1 is formed in a U-shape so as to be able to make a slip by being in contact with the steel ball 2 better.
The utility model discloses a theory of operation does:
when earthquake occurs, the U-shaped steel plate 1, the soft steel damper 4, the SMA memory alloy 3 and the tumbler-type steel ball 2 form a shock insulation layer, the earthquake input energy is dissipated by utilizing the plastic deformation of the steel sheet of the soft steel damper after yielding and the deformation of the SMA memory alloy 3, and meanwhile, the SMA memory alloy wire 3 not only can provide the initial rigidity of a structural system, but also can dissipate energy by utilizing the material characteristics of the SMA memory alloy wire, and the effect of self-resetting after earthquake can be achieved. The upper part of the friction sliding support with the light upper part and the heavy lower part is hollow, the lower part is filled with the small steel balls 5 to form a tumbler type structure, the light upper part and the heavy lower part aim to reduce the gravity center, and the gravity center is more stable when the gravity center is lower. When the upright state is in balance, the distance between the gravity center and the contact point is the smallest, namely the gravity center is the lowest, and the gravity center is always raised after deviating from the balance position. Therefore, the balance of this state is stable, so the steel ball 2 does not fall regardless of the swing.
