Abstract

The invention relates to a liftable modular cushion bridge. The cushion bridge is characterized by comprising a shoreside module and a river module; both the shoreside module and the river module comprise one bridge surface unit and two cushion units; the two cushion units are symmetric from front to back and are fixedly arranged under the bridge surface units; guiding wheels are arranged at left and right symmetric positions outside the bridge surface unit in the shoreside module; vertical guide slots are fixedly arranged in a shoreside corresponding to the two guiding wheels; the guiding wheels are arranged in corresponding vertical guide slots in a sliding way; the inside of the bridge surface unit in the shoreside module and the front and rear end surfaces of the bridge surface unit in the river module are provided with joints; and the inside of the bridge surface unit of the shoreside module is articulated with bridge surface units of adjacent river module and the bridge surface unit of the river module through the joints. The cushion bridge provided by the invention is wide in scope of application. With the adoption of the cushion bridge provided by the invention, the situations that the river is polluted and the landscape coordination is damaged can be avoided; and moreover, the cushion bridge can be lift up to water surface or drop to underwater, thus, the cushion bridge is suitable for being used in rivers in scenic spots.

Description

Liftable modularization air cushion bridge

Technical field

The present invention relates to a kind of bridge.Specifically, be can rise on the water surface when needing, can drop to the liftable modularization air cushion bridge under the water surface when not required.

Background technology

At present, on the river of some scenic spots, often set up the liftable bridge,, supplied pedestrian and vehicle to pass through, can bridge have been dropped under water when not required, to satisfy the needs that landscape is coordinated so that when needed bridge is risen on the water surface.Traditional Liftable type bridge all is to adopt the hydraulic lifting mode to realize the up-down of bridge floor; It is that many group hydraulic legs are set below bridge deck structure; And construct the bearing that is used for the support hydraulic pressure supporting leg in the river bed, realize the up-down of bridge deck structure through stretching of the telescopic oil cylinder in the hydraulic leg.Because this Liftable type bridge is the up-down that realizes bridge deck structure through stretching of telescopic oil cylinder; Hydraulic leg is immersed in the river always; Anticorrosion and antiseep to hydraulic jack is had relatively high expectations; In case oil impregnate appears in hydraulic jack, not only can pollute river, also can destroy the harmony of view.In addition, when running into darker river, require the length of hydraulic leg longer, make the safety of bridge and stability be difficult to guarantee that therefore, this Liftable type bridge is only applicable to not be suitable on the darker river on the more shallow river that the scope of application is restricted.

Summary of the invention

The problem that the present invention will solve provides a kind of liftable modularization air cushion bridge.This liftable modularization air cushion bridge, the scope of application is unrestricted.Adopt this liftable modularization air cushion bridge, the situation that can avoid river being polluted, destroys view harmony takes place.

For addressing the above problem, take following technical scheme:

Liftable modularization air cushion bridge characteristics of the present invention are to comprise bank module and korneforos module.Said bank module and korneforos mould all contain a bridge floor unit and two air cushion unit, said two air cushion unit be before and after symmetry shape be fixed on the bridge floor unit below.Wherein, on the bilateral symmetry position, outside, bridge floor unit in the module of bank directive wheel is arranged all, be fixed with vertical guide groove with this corresponding bank of two directive wheels, said directive wheel is the slip shape and places in the corresponding vertical guide groove.On the rear and front end face of the bridge floor unit in the inside, bridge floor unit in the module of bank and the korneforos module joint is arranged all, inside the bridge floor unit of bank module and between the bridge floor unit of adjacent korneforos module, the bridge floor unit of korneforos module is all hinged by joint each other.

Take such scheme, have the following advantages:

Can find out by such scheme, owing to the present invention includes bank module and korneforos module.Said bank module and korneforos mould all have a bridge floor unit and two air cushion unit, said two air cushion unit be before and after symmetry shape be fixed on the bridge floor unit below.Wherein, there is directive wheel bilateral symmetry position, outside, bridge floor unit in the module of bank on all, is fixed with vertical guide groove with this corresponding bank of two directive wheels, and said directive wheel is the slip shape and places in the corresponding vertical guide groove.On the inside, bridge floor unit in the module of bank and the rear and front end face of the bridge floor unit in the module of korneforos joint is arranged all, the inside, bridge floor unit of bank module and the bridge of adjacent korneforos module

Between the face unit, the bridge floor unit of korneforos module is all hinged by joint each other.When needing to rise; Utilize the aerating device of joining in addition that the air cushion unit is inflated, can make the bridge that constitutes by bank module and korneforos module rise to the water surface, when needing to descend; As long as the gas in the air cushion unit is bled off, the bridge that is made up of bank module and korneforos module is reduced under water.Do not need hydraulic leg just can realize the up-down of bridge.Because employing is inflated the air cushion unit or exitted and realize the up-down of bridge floor,, avoided pollution that river is caused owing to the seepage of the hydraulic jack in the hydraulic leg and the situation of destroying view harmony to take place without hydraulic leg.Again owing to adopt to inflating or exit and realize the up-down of bridge floor in the air cushion unit; Without hydraulic leg, guaranteed the safety and the stability of bridge, make the present invention both be applicable on the more shallow river; Be applicable to that again on the darker river, the scope of application does not receive the restriction of the river depth.

The specific embodiment

As depicted in figs. 1 and 2, liftable modularization air cushion bridge of the present invention comprises bank module and korneforos module.Said bank module and korneforos mould all contain a bridge floor unit 1 and two air cushion unit 2, and said two air cushion unit 2 are rectangle, this two air cushions unit be before and after symmetry shape be fixed on bridge floor unit 1 below.Wherein, 1 outside, bridge floor unit in the module of bank promptly all is equipped with directive wheel 3 on the bilateral symmetry position, one side near the bank; Be fixed with vertical guide groove with this corresponding bank of two directive wheels, said directive wheel 3 is the slip shape and places in the corresponding vertical guide groove, makes the bank module to rise and to descend.All be welded with joint on 1 the inside, bridge floor unit in the module of bank and the forward and backward both ends of the surface of the bridge floor unit 1 in the module of korneforos, the bridge floor unit 1 of 1 the inside, bridge floor unit of bank module and 2 of the bridge floor unit of adjacent korneforos module, korneforos module is all hinged by joint each other.Joint wherein is equal soldering pin ear 4 on the both sides, 1 front and back, bridge floor unit of the adjacent side of the bridge floor unit of adjacent bank module 1 and the bridge floor unit 1 of korneforos module and korneforos module, sell on the ear 4 pin hole processing and be formed by connecting by bearing pin 5.

According to the logical needs that carry, said air cushion unit 2 can be one deck air bag piece, two-layer air bag piece or three layers and form with the upper gasbag piece that the air bag piece in the present embodiment is three layers, and these three layers of air bag pieces are the formula of stacking and are fixed together.
