Background technology
As shown in Figure 1, existing ball shaped steel bearing mainly comprises a upper bracket plate 1, an intermediate panel 2 and a undersetting plate 4 three big parts, has generally also had the tetrafluoro plate 3,5 of carrying effect between three parts.Because said structure is generally vertical stacked, therefore whole bearing has good load-carrying properties and certain displacement function.
For satisfying the needs of normal operating conditions such as expanding with heat and contract with cold, general above-mentioned bearing vertical bridge to direction across bridge on all be reserved with certain clearance.The non-constant of the anti-shear performance of above-mentioned bearing, particularly when being subjected to the huge external force of direction across bridge (as under situations such as violent earthquake) are easy to the phenomenon that causes beam or fall frame, cause serious economy loss but also therefore.
And along with the reinforcement of the antidetonation consciousness of taking precautions against natural calamities, the designer generally more biases toward and consider shockproof factor in existing structure design now.
Therefore, those skilled in the art is devoted to develop a kind of bearing with the anti-fall beam ability of antidetonation.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of two-way ball steel support of single-rail antidetonation damping with the anti-fall beam ability of good antidetonation.
For achieving the above object, the utility model provides the damping of a kind of single-rail antidetonation two-way ball steel support, comprises at least: a upper bracket plate; One piston, described piston have semi-sphere type end face; Be provided with the intermediate panel between described piston and the described upper bracket plate, described intermediate panel has the semi-sphere type bottom surface that cooperates with described piston; One undersetting plate, described lower support plate have baseplane and carrying upper surface, and described piston is arranged on the described carrying upper surface; Comprise that also two are symmetricly set on the speed lock on the described lower support plate, the cylinder barrel of described speed lock is fixedlyed connected with described piston, and the piston rod of described speed lock is fixedlyed connected with described lower support plate; Also comprise a guide rail, described guide rail is arranged between described piston and the described lower support plate, is provided with in the same way with described speed lock; Also comprise a slip collar, connect described upper bracket plate and described piston.
Preferably, described speed lock has adjustable damping value, the different lock speed value of the corresponding described speed lock of different damping values.
Preferably, be respectively arranged with wearing plate between described upper bracket plate and described intermediate panel, described intermediate panel and described piston, described piston and the described lower support plate.
Bearing of the present utility model has been symmetrical arranged 2 speed locks on lower support plate, the speed lock of utilization has the characteristic of translational speed lock value, when the relative sliding velocity of bearing during less than setting value, the speed lock can be free to slide, allow to produce relative motion between piston and the lower support plate, because also be provided with slip collar in the utility model, whole bearing is the multi-orientation type bearing under this state.
When the relative sliding velocity of bearing during greater than setting value, the speed lock is locked and can not be free to slide, do not allow to produce relative motion between piston and the lower support plate, whole bearing is vertical or horizontal locked under this state, but owing to there is slip collar, the upper bracket plate is also playing a role, make whole bearing can and only can slide in one direction, become an one-way type bearing.
Structure and principle thus, bearing of the present utility model can be a conversion value with a movement velocity of setting, and changes between multidirectional bearing and one-way support, has had both advantages concurrently, thereby compare with the bearing of prior art, have the anti-fall beam technique effect of better antidetonation.
Since the utility model also between piston and lower support plate, with the speed lock be provided with a guide rail in the same way, make both between relatively move more smooth and easy.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
