Abstract

The utility model provides a spring bridge post buffer stop, including the bridge post, the bridge post outside sets up the guard plate bottom plate, sets up the gyro wheel in the middle of guard plate bottom plate and the bridge post, and the gyro wheel sets up the sleeve along bridge post surface motion in the middle of guard plate bottom plate and the guard plate skin, and the sleeve divide into big sleeve, little sleeve and spring, and the spring sets up in the middle of little sleeve, big sleeve, and little sleeve cup joints with big sleeve. This device sets up the sleeve through guard plate bottom plate and the outer centre of guard plate, avoids the spring compression to warp, realizes buffer stop's straight line elastic motion, and when ship striking bridge column, the gyro wheel autogiration reduces the effort that ship striking bridge column, can produce the reaction force of buffering simultaneously to make ship and bridge column be difficult for impairedly, have novel structure, simple to operate, the characteristics of easily realizing.

Description

Spring bridge post buffer stop

Technical Field

The utility model relates to a bridge post buffer stop technical field particularly, relates to a spring bridge post buffer stop.

Background

With the vigorous development of the transportation industry and the economic construction, the large bridges crossing the river and the sea are more and more, so that the collision accidents of the bridge piers are increased sharply, a plurality of serious and serious malignant collision events occur during the operation of the large bridges, and some traffic trunk lines and navigation channels are blocked for two years. In China, the bridge collision accident of a ship also frequently occurs, millions of major accidents with direct economic loss also frequently occur, each collision accident causes a serious tragedy that the bridge destroys people, and the economic loss of interrupting traffic and repairing lines is serious year by year. However, the reduction of the service life, the safety and the shock resistance of the bridge is certain, and for the situation, related researches are carried out by traffic departments of many countries, a ship bridge collision theory is provided, and pier protection facilities are designed. The anti-collision device of current bridge often the structure is complicated when the design, and the cost is very expensive to it is also very loaded down with trivial details to install.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a spring bridge post buffer stop to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a spring bridge post buffer stop, includes the bridge post, the bridge post outside sets up the guard plate bottom plate, set up the gyro wheel in the middle of guard plate bottom plate and the bridge post, the gyro wheel is along bridge post surface motion, set up the sleeve in the middle of guard plate bottom plate and the guard plate skin, the sleeve divide into big sleeve, little sleeve and spring, the spring sets up in the middle of little sleeve, big sleeve, little sleeve cup joints with big sleeve.

Further, the small sleeve is riveted or welded with the bottom plate of the protection plate, and the large sleeve is riveted or welded with the outer layer of the protection plate.

Further, the base of the roller is riveted or welded with the bottom plate of the protection plate.

Further, the outer side of the protection plate is wrapped with a flexible material.

Furthermore, the flexible material is a thermoplastic rubber layer.

Further, the thermoplastic rubber plastic layer is a polyethylene layer.

The utility model discloses a theory of operation: when boats and ships striking bridge column, can produce very big impact force, this device adopts the design of gyro wheel rotation type, need not add external auxiliary design, the effort that can produce when striking is weakened through the gyro wheel rotation automatically, utilize the spring to produce the reaction force of buffering simultaneously, make boats and bridge column difficult impaired, and this device outside is provided with the protective layer, utilize the protective layer can suitably alleviate the effort that boats and ships striking bridge column, protection boats and bridge upper part receive the harm less, personnel on the protection boat do not receive the bruise simultaneously.

Compared with the prior art, the utility model discloses following beneficial effect has: 1. the device has simple structure, convenient installation and easy realization; 2. the protective layer is arranged on the outer side of the device, the acting force of a ship impacting an abutment column can be properly reduced by utilizing the protective layer, the ship and parts on the bridge are protected from being damaged, and meanwhile, personnel on the ship are protected from being damaged by collision; 3. this device modern design has simple swift characteristics in bridge post anticollision structure's design.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is the utility model discloses a spring bridge post buffer stop's overall structure schematic diagram.

In the figure: 1. bridge column, 2 protective plate bottom plates, 3 rollers, 4 protective plate outer layers, 5 large sleeves, 6 small sleeves and 7 springs.

Detailed Description

The following, with reference to the drawings and the detailed description, further description of the present invention is made:

as shown in fig. 1, a spring bridge post buffer stop, including bridge post 1, 1 outside of bridge post sets up guard plate bottom plate 2, set up gyro wheel 3 in the middle of guard plate bottom plate 2 and the bridge post 1, gyro wheel 3 is along 1 surface motion of bridge post, set up the sleeve in the middle of guard plate bottom plate 2 and the outer 4 of guard plate, the sleeve divide into big sleeve 5, little sleeve 6 and spring 7, spring 7 sets up in the middle of little sleeve 6, big sleeve 5, little sleeve 6 connects with big sleeve 5.

When the ship strikes the bridge column, can produce very big impact force, this device adopts the design of gyro wheel rotation type, need not add external auxiliary design, the effort that can produce when striking is weakened through 3 rotations of gyro wheel automatically, utilize spring 7 to produce the reaction force of buffering simultaneously, make ship and bridge column difficult impaired, and this device outside is provided with the outer 4 of protection plate, utilize the outer 4 of protection plate can suitably alleviate the effort that the ship strikes the bridge column, protection ship and bridge upper part receive the harm less, personnel on the protection ship do not receive the bruise simultaneously.
