Abstract
The utility model discloses a kind of lift suspension bridge, including beam body, beam body be respectively arranged at two ends with lifting column, the top promoting column is provided with lifting crossbeam, and the bottom at the two ends of beam body is provided with lifting joist, promotes joist and promotes and be provided with lifting device between crossbeam.Lifting device includes hoist engine and pulley mechanism, or includes suspension rod and lifting jack mechanism.Promoting column and be provided with bracket, beam body is placed on bracket when down position.Can meet provisional navigation requirement, the lifting lifting suspension bridge is convenient, flexible, rapid, and its process is steady, quick, safety.
Description
Technical field
This utility model relates to a kind of science of bridge building technology, particularly relates to a kind of lift suspension bridge.
Background technology
In Bridge Construction technical field, suspension bridge as the structure of the barriers such as a kind of provisional leap basin, gully,
When construction as considered the needs of navigation, then the elevation arranged is higher, causes uneconomical；But generally require and meet certain navigation
Needs, it is therefore desirable to navigable is set on suspension bridge.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting lift suspension bridge convenient, flexible, rapid.
The purpose of this utility model is achieved through the following technical solutions:
Lift suspension bridge of the present utility model, including beam body, described beam body be respectively arranged at two ends with lifting column, described in carry
The top rising column is provided with lifting crossbeam, and the bottom at the two ends of described beam body is provided with lifting joist, described lifting joist and lifting
Lifting device it is provided with between crossbeam.
The technical scheme that thered is provided by above-mentioned this utility model it can be seen that the lift that provides of this utility model embodiment just
Bridge, meets provisional navigation requirement, and the lifting lifting suspension bridge is convenient, flexible, rapid, and its process is steady, quick, safety.
Accompanying drawing explanation
The suitable bridge of the lift suspension bridge that Fig. 1 provides for this utility model embodiment is to structural representation.
The direction across bridge structural representation of the lift suspension bridge that Fig. 2 provides for this utility model embodiment.
The lift suspension bridge that Fig. 3 provides for this utility model embodiment promote after suitable bridge to structural representation.
The lift suspension bridge that Fig. 4 provides for this utility model embodiment promote after direction across bridge structural representation.
In figure:
1-promotes column, 2-promotes crossbeam, 3-bracket, 4-suspension rod, 5-anchor head, 6-lifting jack, 7-beam body, 8-promote
Joist.
Detailed description of the invention
This utility model embodiment will be described in further detail below.
Lift suspension bridge of the present utility model, its preferably detailed description of the invention is:
Including beam body, described beam body be respectively arranged at two ends with lifting column, the top of described lifting column is provided with lifting horizontal stroke
Beam, the bottom at the two ends of described beam body is provided with lifting joist, is provided with lifting device between described lifting joist and lifting crossbeam.
Described lifting device includes hoist engine and pulley mechanism, or includes suspension rod and lifting jack mechanism.
Described lifting column is provided with bracket, and described beam body is placed on described bracket when down position.
Lift suspension bridge of the present utility model, meets provisional navigation requirement, the lifting of lifting suspension bridge is convenient, flexibly,
Rapidly, its process steadily, quickly, safety.
Specific embodiment one:
As shown in Figures 1 to 4, along bridge to arranging braking pier at bridge two ends, each braking pier is respectively 4 root posts, its
In promote column near two of bridge center for upstream and downstream, upstream and downstream lifting column upper end sets lifting crossbeam.Promote column
Height need to meet the needs of navigation.
Upstream and downstream promotes the inner side of column and arranges bracket, during trestle work, promotes joist and is placed on bracket.
Beam body is supported on lifting joist.Beam body separates with adjacent superstructure and is not connected to, and is beneficial to the lifting of beam body
And decline.Beam body is reliably connected with promoting joist, it is ensured that the stability during upper and lower displacement.
Promoting crossbeam and be respectively connected 2 piece suspension rods in upstream and downstream with promoting between joist, full-bridge 4 is with suspension rod.Suspension rod upper end sets
Anchor head, lower end installation lifting jack, make lifting joist rise by 4 jack of simultaneous tension, thus realize beam body and rise,
Can open the navigation or air flight under bridge, make lifting joist decline by loosening jack, thus realize beam body and decline, beam body and adjacent upper structure
Docking, suspension bridge normally works.Suspension bridge promotes and descends through lifting jack and realizes, and its process is steady, quick, safety.
Detailed description of the invention two:
In embodiment one, it is possible to use hoist engine and pulley mechanism replace suspension rod and lifting jack mechanism, with
Sample can realize hoisting and declining of suspension bridge.
The beneficial effects of the utility model can be summarized as two aspects:
(1) achieve the navigation in work progress require and set up the organic unity of suspension bridge economy.
(2) this suspension bridge elevating mechanism is simple, reliable, steadily, safely, quickly.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is as the criterion with the protection domain of claims.
