Abstract
The utility model discloses a kind of cable-stayed type and open trestle, it comprises four groups of lattice columns for vertical load-bearing, distribution base is fixed with at the top of each group lattice column, distribution base is fixed with hoist engine, horizontal buttress has been set respectively in the inner side of both sides lattice column, be provided with between homonymy two groups of lattice columns and strengthen framed bent Temporary Piers, two identical one-sided bridge constructions extend to a bridge central authorities composition overall bridge construction that can open respectively, the unlatching section that each one-sided bridge construction is included fixed end and is rotatedly connected by turning hinge and fixed end, on the reinforcement framed bent Temporary Piers that the front end of the fixed end of an one-sided bridge construction is fixed on homonymy and the rear end of the unlatching section of the one-sided bridge construction of this side and front portion is supported on respectively when plan-position to be strengthened on framed bent Temporary Piers and horizontal buttress, the hoist engine of the same side direct tractive of drawing rope of drawing is to the front end of the unlatching section of this side.This structure increases the navigational clearance of trestle.
Description
Technical field
The utility model relates to Bridge Construction field, and the utility model particularly relates to cable-stayed type and opens trestle.
Background technology
Knownly at present mainly adopt door type structure trestle mode when there being the waters of navigation demand to carry out bridge construction, this kind of construction method only can allow small-sized, short boats and ships to pass through, and as excessive in navigational clearance, can impact the construction of bridge both sides, make to have inconvenient traffic, be unfavorable for the turnover of construction machinery, material.In addition, a kind of lifting appliance is disclosed in the patent of publication number CN202369929U and CN202688850U, this device only can provide limited navigational clearance, and the limit height of its navigational clearance is its height exceeding the water surface of lattice column arranged and difference of suspension bridge height.
Summary of the invention
The purpose of this utility model is to overcome existing technological deficiency, provides a kind of and can ensure the unobstructed of construction period navigation channel, and the cable-stayed type of the convenience and economy that can improve construction opens trestle.
The utility model is achieved through the following technical solutions:
A kind of cable-stayed type opens trestle, it comprises spaced four groups of lattice columns for vertical load-bearing along vertical bridge to bridge floor both sides, distribution base is fixed with at the top of each group lattice column, distribute on base at each and be all fixed with hoist engine, horizontal buttress has been set respectively in the inner side of both sides lattice column, between homonymy two groups of lattice columns, be provided with at least one strengthen framed bent Temporary Piers, two identical one-sided bridge constructions extend to a bridge central authorities composition overall bridge construction that can open respectively, the unlatching section that each one-sided bridge construction is included fixed end and is rotatedly connected by turning hinge and fixed end, on the reinforcement framed bent Temporary Piers that the front end of the fixed end of an one-sided bridge construction is fixed on homonymy and the rear end of the unlatching section of the one-sided bridge construction of this side and front portion is supported on respectively when plan-position to be strengthened on framed bent Temporary Piers and horizontal buttress, the hoist engine of the same side direct tractive of drawing rope of drawing is to the front end of the unlatching section of this side.
The beneficial effect that compared with the prior art the utility model has is:
(1) oblique roller is adopted can to increase the navigational clearance of trestle, to guarantee that the high boats and ships of superstructure can be opened the navigation or air flight smoothly.
(2) trestle does not affect the construction function of trestle after setting level, and can ensure that trestle restores the smooth of rear body structure surface, be conducive to the turnover of construction equipment and material between different construction plant, can improve efficiency of construction, save construction cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of cable-stayed type of the present invention opens trestle opening in trestle;
Fig. 2 is that a kind of cable-stayed type of the present invention opens the non-opening schematic diagram of trestle in trestle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, use of the present invention is described further.
A kind of cable-stayed type of the present utility model as shown in drawings opens trestle, it comprises spaced four groups of lattice columns 1 for vertical load-bearing along vertical bridge to bridge floor both sides, distribution base is fixed with at the top of each group lattice column, distribute on base at each and be all fixed with hoist engine 2, horizontal buttress 5 has been set respectively in the inner side of both sides lattice column, between homonymy two groups of lattice columns, be provided with at least one strengthen framed bent Temporary Piers, two identical one-sided bridge constructions extend to a bridge central authorities composition overall bridge construction that can open respectively, the unlatching section 4 that each one-sided bridge construction is included fixed end and is rotatedly connected by turning hinge and fixed end, on the reinforcement framed bent Temporary Piers that the front end of the fixed end of an one-sided bridge construction is fixed on homonymy and the rear end of the unlatching section of the one-sided bridge construction of this side and front portion is supported on respectively when plan-position to be strengthened on framed bent Temporary Piers and horizontal buttress, the hoist engine 2 of the same side drawing rope 3 of drawing directly tractive to the front end of the unlatching section of this side.
When there being navigational clearance requirement, starting hoist engine 2 simultaneously, by drawing rope 3, unlatching section 4 being opened, be opened into after reserving certain navigation width, allow ship 6 to pass through.After ship 6 passes through, start hoist engine 2, release drawing rope 3, makes movable bridge structure set level gradually, until again drop on horizontal buttress 5, recovers trestle and normally uses.
Claims (1)
1. a cable-stayed type opens trestle, it comprises spaced four groups of lattice columns for vertical load-bearing along vertical bridge to bridge floor both sides, it is characterized in that: be fixed with distribution base at the top of each group lattice column, distribute on base at each and be all fixed with hoist engine, horizontal buttress has been set respectively in the inner side of both sides lattice column, between homonymy two groups of lattice columns, be provided with at least one strengthen framed bent Temporary Piers, two identical one-sided bridge constructions extend to a bridge central authorities composition overall bridge construction that can open respectively, the unlatching section that each one-sided bridge construction is included fixed end and is rotatedly connected by turning hinge and fixed end, on the reinforcement framed bent Temporary Piers that the front end of the fixed end of an one-sided bridge construction is fixed on homonymy and the rear end of the unlatching section of the one-sided bridge construction of this side and front portion is supported on respectively when plan-position to be strengthened on framed bent Temporary Piers and horizontal buttress, the hoist engine of the same side direct tractive of drawing rope of drawing is to the front end of the unlatching section of this side.
