Description
Technical field
The present invention relates to building engineering field, relate in particular to a kind of two-way ball steel support of two guide rail antidetonation damping that is applied to bridge.
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 receiving the huge external force of direction across bridge (as under situation 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 in existing structure design, considers shockproof factor now.
Therefore, those skilled in the art is devoted to develop a kind of bearing with the anti-fall beam ability of antidetonation.
Summary of the invention
Because the above-mentioned defective of prior art, technical problem to be solved by this invention provides a kind of two-way ball steel support of two guide rail antidetonation damping with the anti-fall beam ability of good antidetonation.
For realizing above-mentioned purpose, the invention provides the two-way ball steel support of a kind of pair of guide rail antidetonation damping, comprise at least: a upper bracket plate; One sliding panel, said sliding panel are arranged on said upper bracket plate below and are connected with said upper bracket plate through a trip; One piston, said piston have plane and semi-sphere type bottom surface on one; One end basin is provided with the intermediate panel between basin of the said end and the said piston, and said intermediate panel has the semi-sphere type end face that cooperates with said piston; One undersetting plate, said lower support plate have the baseplane and carry upper surface, and basin of the said end is arranged on the said carrying upper surface; Two are symmetricly set on the speed lock on the said lower support plate, and the cylinder barrel of said speed lock is fixedly connected with basin of the said end, and the piston rod of said speed lock is fixedly connected with said lower support plate; Also comprise one first guide rail, said first guide rail is arranged between said sliding panel and the said piston; One second guide rail, said second guide rail are arranged between basin of the said end and the said lower support plate, are provided with in the same way with said speed lock; Said first guide rail and the vertical setting on different level of said second guide rail.
Preferably, said speed lock has adjustable damping value, the different lock speed value of the corresponding said speed lock of different damping values.
Preferably, be respectively arranged with wearing plate between said piston and said intermediate panel, said intermediate panel and basin of the said end, basin of the said end and the said lower support plate.
Bearing of the present invention has been symmetrical set 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, and allows to produce relative motion between end basin and the lower support plate, and 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 end basin and the lower support plate, whole bearing edge locks with the direction of speed lock second guide rail in the same way under this state, but is still playing a role along the direction of first guide rail; Whole bearing can be slided along the direction of first guide rail, become an one-way type bearing.
Structure and principle thus, bearing of the present invention can be a conversion value with the movement velocity set, between multidirectional bearing and one-way support, changes, and has had both advantages concurrently, thereby has compared with the bearing of prior art, has the anti-fall beam technique effect of better antidetonation.
Because the present invention also is provided with two respectively in vertical direction with guide rail, when a direction with guide rail was locked, another direction with guide rail can also play a role.
Below will combine accompanying drawing that the technique effect of design of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.
Description of drawings
Fig. 1 is the structural representation of a ball shaped steel bearing of the prior art;
Fig. 2 is the broken section structural representation of the present invention's one specific embodiment;
Fig. 3 is the plan structure sketch map of the present invention's one specific embodiment.
The specific embodiment
Like Fig. 2, embodiment shown in Figure 3, the two-way ball steel support of of the present invention pair of guide rail antidetonation damping comprises at least: a upper bracket plate 2, one sliding panels 4, one pistons 6, one end basin 7, one undersetting plates 12.
Piston 6 has plane and semi-sphere type bottom surface on one.Guide rail 5 (detailed description sees below) is set on the last plane of piston 6.
End basin 7 has semi-sphere type bottom surface.Be provided with intermediate panel 11 between end basin 7 and the piston 6.Intermediate panel 11 has the end face of the protruding spherical that is slidingly matched each other with end basin 7, to provide bearing needed corner.
Be respectively arranged with the wearing plate 9 of modified ultra-high molecular weight polyethylene material between piston 6 and intermediate panel 11, intermediate panel 11 and end basin 7, end basin 7 and the lower support plate 12,, reduce slip resistance in order to reduce slide coefficient.
Bearing of the present invention also comprises two speed locks 8 that are arranged on symmetrically on the lower support plate 12.The cylinder barrel 81 of speed lock 8 is fixedly connected with end basin 7, and the piston rod 82 of speed lock 8 is fixedly connected with lower support plate 12.
Bearing of the present invention comprises one first guide rail 5.First guide rail 5 is arranged between sliding panel 4 and the piston 6, and slide-and-guide is provided, and transmits transverse load.
Bearing of the present invention also comprises one second guide rail 10.Second guide rail 10 is arranged between end basin 7 and the lower support plate 12, is provided with in the same way with speed lock 8.Second guide rail 10 provides the guiding of sliding relatively between end basin 7 and the lower support plate 12, and transmits transverse load.
In use, when the relative sliding velocity of bearing during less than setting value, speed lock 8 can be free to slide, and allows to produce relative motion between end basin 7 and the lower support plate 12, and whole bearing is the multi-orientation type bearing under this state.
When the relative sliding velocity of bearing during greater than setting value; Speed lock 8 is locked and can not be free to slide; Do not allow to produce relative motion between end basin 7 and the lower support plate 12, whole bearing edge locks with the direction of speed lock 8 second guide rail 10 in the same way under this state, but is still playing a role along the direction of first guide rail 5; Whole bearing can be slided along the direction of first guide rail 5, become an one-way type bearing.
Structure and principle thus, bearing of the present invention can be a conversion value with the movement velocity set, between multidirectional bearing and one-way support, changes, and has had both advantages concurrently, thereby has compared with the bearing of prior art, has the anti-fall beam technique effect of better antidetonation.
