Description
Technical field
The utility model belongs to technical field of bridge construction, and in particular to a kind of integral lifting used in navigable waters
Movable trestle.
Background technology
At present, with the development of large bridge, the construction of deep water foundation is more and more, and the function to steel trestle is also carried
Go out requirement higher, not only to meet the current requirement of Construction traffic, while also to meet the requirement of waters ship navigation, and
It is required that esy to use, safe and reliable.
The traditional construction method of trestle：To meet waters headway requirement, stack very high is built in ship navigation position
Bridge navigable, while building as navigable the connection trestle of height in navigable rear and front end or building the very steep company of the gradient
Connect trestle.
It is obvious to there is shortcoming in traditional trestle：
1st, navigable trestle is higher, and trestle top surface vehicle pass-through is dangerous.
2nd, steel pipe pile foundation and attachment structure are accordingly increased, and structure stress is poor, and security risk is high.
3rd, material usage is larger, and construction cost is high.
Therefore, a kind of integral lifting movable trestle used in navigable waters is studied to seem to meet the smooth navigation of ship
It is very necessary.
The content of the invention
The utility model is that the bridge for solving to be used in navigable waters can meet the current requirement of Construction traffic and can expire
A kind of technical problem of the requirement of sufficient waters ship navigation, there is provided integral lifting movable trestle used in navigable waters.
The technical solution adopted in the utility model is as follows：
A kind of integral lifting movable trestle used in navigable waters, including movable trestle girder, be arranged on trestle lead to
The Conveyor belt stake at boat hole or so two ends, lifting tower, hoist engine, boom hoist cable, lifting sill and lifting entablature, it is described
Lifting tower is door opening formula structure, and the Conveyor belt stake top portion at trestle navigable or so two ends fixedly mounts a lifting tower, institute respectively
State movable trestle girder and be arranged on left and right two and lifted between towers, the length of movable trestle girder and the length phase of trestle navigable
Match somebody with somebody, bottom of movable trestle girder or so two ends are respectively perpendicular setting one and lift sill, the top for lifting tower is set in lifting
Crossbeam, lifting entablature is oppositely arranged with lifting sill, and the two ends for lifting entablature are respectively provided with a hoist engine, the lower horizontal stroke of lifting
The two ends of beam are connected by boom hoist cable with hoist engine respectively.
The inner side of left and right two ends lifting tower is oppositely arranged a slideway stopping means, the two spacing dresses of the slideway being oppositely arranged respectively
The distance between put and to match with the width of movable trestle girder.
Movable trestle girder is assembled using Bailey bracket.
The beneficial effects of the utility model：The utility model design is simple, structure stress is reasonable, construction cost is relatively low, behaviour
Make easy, safe and reliable, the utility model meets vehicle pass-through, ship in the case where bridge trestle whole height is not improved
The bidirectional demand of navigation, successfully solves the construction difficult problem of ship navigation in the bridge construction of waters, reduces bridge trestle cost,
Can also evade the dangerous influence that natural cause is caused on bed rearrangement bridge trestle, the utility model can effectively, facilitate water in time
Domain ship navigation, with good application value.

Specific embodiment
As shown in Figure 1, 2, 3, a kind of integral lifting movable trestle used in navigable waters, including movable trestle girder
1st, Conveyor belt stake 9, lifting tower 3, hoist engine 4, boom hoist cable 5, the lower horizontal stroke of lifting at trestle navigable or so two ends are arranged on
Beam 6 and lifting entablature 7, the lifting tower 3 are door opening formula structure, the top of Conveyor belt stake 9 at trestle navigable or so two ends
Fixed installation one respectively lifts tower 3, and the movable trestle girder 1 is assembled using Bailey bracket, and movable trestle girder 1 is arranged on
Left and right two is lifted between tower 3, and length and the length of trestle navigable of movable trestle girder 1 match, movable trestle girder 1
Bottom or so two ends are respectively perpendicular setting one and lift sill 6, and the top for lifting tower 3 sets lifting entablature 7, lifts entablature
7 are oppositely arranged with lifting sill 6, and the two ends for lifting entablature 7 are respectively provided with a hoist engine 4, lift the two ends point of sill 6
Not Tong Guo boom hoist cable 5 be connected with hoist engine 4.
To ensure that hoisting type movable trestle smoothly rises or safety declines in place, the inner side difference of left and right two ends lifting tower 3
It is oppositely arranged the distance between a slideway stopping means 8, two slideway stopping means 8 being oppositely arranged and movable trestle girder 1
Width matches.
The utility model coordinates 90kw vibration hammer rapping Conveyor belt pile driving constructions, trestle base using buoyancy tank and 50t crawler cranes
Plinth stake uses steel pipe manufacturing, is intersected with I-steel between Conveyor belt stake and is integrated with lateral connection reinforcing, Conveyor belt stake top
Face is installed by horizontal I-steel and navigable Bailey bracket movable trestle girder successively.Movable trestle girder two ends Conveyor belt stake platform
Two hoisting type steel-pipe pile lifting towers are installed at top, and remote control or manual controlled motor cause that many hoist engine synchronous working liftings are whole
Body formula movable trestle girder, movable trestle girder gradually rises or declines in lifting tower slideway stopping means position vertical direction,
Ensure reserved navigable smooth opening before ship passes through, can decline after and be connected trestle with two ends and smoothly close up,
Close up vehicle on rear trestle to can continue to pass through.
Described remote control or manual controlled motor are key control switch, that is, lifted pyller frame and lifting system install with
Afterwards, navigable two ends lifting hoist engine motor circuit is carried out and is coupled, it is ensured that integral lifting navigable trestle synchronously rises,
Or synchronous decline.
Meet vehicle pass-through, ship in the case of the utility model has the advantage of bridge trestle whole height is not improved to lead to
The bidirectional demand of boat.Using at trestle navigable two ends, lifting device is set, by navigation planned time section before ship arrival,
By the certain height of navigable movable trestle Integral hoisting, it is ensured that Navigation in Navigable is smoothed out, and successfully solves waters bridge
The construction difficult problem of ship navigation, reduces bridge trestle cost in beam construction, can also evade natural cause to bed rearrangement bridge trestle
The dangerous influence for causing.
