Description

A kind of detachable pedestrian overcrossing

Technical field

The utility model relates to a kind of detachable pedestrian overcrossing, belongs to technical field of buildings.

Background technology

The construction in current most domestic city, be constantly updating and extending of basis, old city, there is the prominent question of inadequate natural endowment in it on headspace.And along with urban economy development, population is constantly increasing, this is proposing stricter requirement to path area.And with urban road construction the closest be exactly various skies bridge constructions, particularly in the location of some traffic congestions, pedestrian overcrossing has precedence over underpass and has become primary selection.

On overline bridge is built, the fixed construction of domestic many employings at present, but there is certain limitation in fixed overline bridge.First be Quantity and the installation location of overline bridge, urban road construction should with usual peak traffic condition for benchmark, to ensure the normal performance of function path, but the urban traffic conditions peak position period is not long, and the arriving time on peak everywhere, city also stragglyly to differ, time this just causes majority, the idle situation of overline bridge facility, can't but be the waste of social traffic resource.

Secondly, build unit price lattice height and determine cannot carry out Large scale construction within short-term with construction period length, very easily occur the worse situation of construction period traffic conditions.Therefore, under the environment that social road capital construction is in great demand, be badly in need of a kind of supplementary means and supplemented.

Utility model content

For solving the problem, the utility model proposes the detachable pedestrian overcrossing of the little and conveniently assemble and disassemble of a kind of short construction period, road occupying area.

The technical scheme that the utility model adopts is: a kind of detachable pedestrian overcrossing, comprises two portable bridge piers, and is set up in the bridge floor on two portable bridge piers, and the side of two portable bridge piers is equipped with ladder module; Described two portable bridge piers comprise base and are located at outer support post and the inner support post of base top, and be located at the universal wheel mechanism of base bottom, inner support post is provided with thing 5, and be positioned at the inside of outer support post, wherein the support column at a bridge pier center is provided with the hydraulic gear be connected with bridge floor end, be provided with hydraulic vernier device between bottom the side and bridge floor of this bridge pier outer support post, be provided with at the top of another bridge pier and agree with seat for the fixing bridge floor other end; Described ladder module is made up of ladder main body and the multiple cascaded surfaces be detachably arranged on ladder main body inclined-plane.

Further, also comprise a hoist, and be arranged on the ladder main body side of a ladder module.

Further, the medial surface agreeing with seat described in is also provided with multiple for guiding the roller agreed with.

Further, the bottom of described ladder main body is provided with ladder movable pulley.

Further, the both sides of described bridge floor and two ladder main bodys are also provided with dismountable railing.

Compared with prior art, it has following beneficial effect to the utility model:

1. it can realize the holistic conformation of pedestrian overcrossing by load wagon and mobile crane, and operation is very easy, builds with unloading process very smooth and easy.

2. can realize assembly and disassembly fast, not only substantially increase convenience, also help the standardization and scale that realize producing, more greatly reduce the cost of overline bridge repair and maintenance.

3. bridge floor adopts environmental protection the most, engineering compounded plastics that cost performance is the highest, not only moderate, having again excellent mechanical property simultaneously, avoiding because all building caused larger own load by steel simultaneously.

4. reduce technical costs and labor cost that overline bridge builds, achieve and can be recycled.

5. be applicable to that common crossing, crossroad and T-shaped road junction etc. are multiple specially builds demand.

Detailed description of the invention

Clearly understand to make the purpose of this utility model, technical scheme and advantage, below in conjunction with drawings and the embodiments, the utility model is further elaborated, should be understood to, detailed description of the invention described herein only in order to explain the utility model, and is not used in restriction the utility model.

The detachable pedestrian overcrossing of one as shown in Figure 1 to Figure 3, comprises two portable bridge piers 1, and the side of bridge floor 2, two the portable bridge piers 1 be set up on two portable bridge piers 1 is equipped with ladder module 3, described two portable bridge piers 1 comprise base 11 and are located at outer support post 12 and the inner support post 13 at base 11 top, and the universal wheel mechanism 14 be located at bottom base 11, inner support post 13 is provided with thing 5, and be positioned at the inside of outer support post 12, wherein the inner support post 13 at bridge pier 1 center is provided with the hydraulic gear 4 be connected with bridge floor 2 end, hydraulic gear 4 can realize horizontally rotating of bridge floor 2 and vertically rotate, hydraulic vernier device 5 is provided with between bottom the side and bridge floor 2 of this bridge pier 1 outer support post 12, the angle of the adjustable bridge floor 2 of hydraulic vernier device 5, be provided with at the top of another bridge pier 1 and agree with seat 6 for fixing bridge floor 2 other end, described ladder module 3 is made up of ladder main body 31 and the multiple cascaded surfaces 32 be detachably arranged on ladder main body 31 inclined-plane, ladder main body 31 has the jack for cascaded surface 32 of planting, and is provided with spring self-locking mechanism in jack.
