Abstract
The utility model discloses a speed lock-up support and relates to bridge technology. The speed lock-up support comprises an upper anchor plate component and a lower anchor plate component, also comprises an upper sliding plate component, a lower sliding plate component and a lock-up device; wherein the upper sliding plate component is fixedly connected with the upper anchor plate component, the lower sliding plate component is fixedly connected with the lower anchor plate component; the upper sliding plate component and the lower sliding plate component are in sliding fit through a guide rail component and are respectively fixedly connected with a cylinder body and a piston of the lock-up device; and the action direction of the lock-up device is parallel to that of a guide rail. The speed lock-up support has the advantages that the force of the bridge structure is more even, the performance is more stable, and the construction cost can be effectively reduced.
Description
Technical field
The utility model relates to bridge technology.
Background technology
Bridge pad is the supporting part of bridge span structure, and it passes to pier with the bearing reaction of bridge span structure, and guarantees that bridge span structure satisfies deformation requirements under load action.Present bridge pad is divided into three kinds of fixed, one-way type and multi-orientation types, and the bridge pier that installs and fixes the type bearing is defined as fixed abutment, and all the other bridge piers are defined as rocking pier; Fixed abutment and rocking pier are all born vertical load, are then only born by fixed abutment by the horizontal load that earthquake or braking force of train produce.In order to make rocking pier can work to bear horizontal load when needed equally, the utility model provides a kind of bearing that has the speed lock.
The utility model content
Technical problem to be solved in the utility model is, speed locking bearing is provided, when adopting bridge of the present utility model because factors such as wind-force, earthquake when producing bigger vibrations, can be disperseed load.
The technical scheme that the utility model solve the technical problem employing is, speed locking bearing, comprise the anchor plate assembly, descend the anchorage board component, also comprise the upper sliding plate assembly of fixedlying connected, the lower slider board component of fixedlying connected and speed lock with following anchorage board component with last anchor plate assembly; Upper sliding plate assembly and lower slider board component form by guide assembly and are slidingly matched, and the upper sliding plate assembly is fixedlyed connected with piston with the cylinder body of speed lock respectively with the lower slider board component, and the action direction of speed lock is parallel with the guide rail direction.
Further, the speed lock is two, is separately positioned on the both sides of bearing.The lower slider board component is fixedlyed connected with the piston of speed lock by 4 fixed blocks, and the upper sliding plate assembly is fixedlyed connected with the cylinder body of speed lock.Sliding contacting part branch at upper sliding plate assembly and lower slider board component is provided with wearing plate.Described speed lock is provided with sealing device.
The beneficial effects of the utility model are, for adopting bridge of the present utility model, under normal circumstances, the speed lock plays a role hardly, the horizontal movement that allows beam body corner and temperature deformation to cause, brake force, wind carry or the seismic (seismal effect under, the speed lock can automatically lock, make structure become two or more anchor blocks by an anchor block under the normal condition, the load of superstructure is distributed to a plurality of block of wood effectively to get on, make the stressed more even of structure, performance is more stable, and can effectively reduce construction costs.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1, Fig. 2 are structural representations of the present utility model.
Fig. 3 is the speed lock schematic appearance that the utility model relates to.
The specific embodiment
The speed lock that the utility model relates to belongs to existing product, can be interpreted as the automatic switch that a speed of related movement according to piston is judged and whether worked simply, when the piston speed of related movement (is caused by factors such as earthquake or big brake force) during lock speed more than or equal to design, the speed lock is carried out lock function, this moment, upper sliding plate assembly 3 and lower slider board component 4 can't slide, bearing can be regarded as a fixed bearing, works to share horizontal load.
Referring to Fig. 1.
The utility model comprises anchor plate assembly 1, following anchor plate 2 assemblies, upper sliding plate assembly 3, lower slider board component 4, speed lock 5.Upper sliding plate assembly 3 is fixedlyed connected with last anchor plate assembly 1, lower slider board component 4 is fixedlyed connected with following anchorage board component 2, upper sliding plate assembly 3 and lower slider board component 4 form by guide assembly 7 and are slidingly matched, and make the upper sliding plate assembly 3 can be along guide rail and the 4 relative slips of lower slider board component.Upper sliding plate assembly 3 is fixedlyed connected with the cylinder body of speed lock 5, lower slider board component 4 is fixedlyed connected with the piston of speed lock 5 by fixed block 6, the action direction of speed lock 5 is parallel with the guide rail direction, that is, piston is consistent with respect to the glide direction of cylinder body with the glide direction of guide rail.Upper sliding plate assembly 3 is fixedlyed connected with the cylinder body of speed lock.
Thinking of the present utility model is the effect by the speed lock, when vibrations take place bridge, load is distributed on the more bridge pier, the piston of speed lock and cylinder body should be maintained fixed with last anchor plate and following anchor plate respectively, and any various embodiments based on this design all belong to interest field of the present utility model.
