Abstract
The utility model provides a kind of for driving the driving device of steel tube arch bridge arch center supporting structure, including rack, the head end of rack and end are provided with connection steel member, its machine frame inside is provided with multiple roll shafts, it is connected by the axle center column of its end using chain between roll shaft, roll shaft chain is formed it into, fills bar steel plate in roll shaft chain.By being connected to form roll shaft chain in the multiple roll shafts of machine frame inside, and bar steel plate is set inside roll shaft chain, can by arch supporting structure and the gravity laod of arch be evenly distributed on each roll shaft, have large carrying capacity, stability is good, and the rolling resistance of roll shaft is small and can continuous rolling.
Description
Technical field
It is especially a kind of for driving the drive of steel tube arch bridge arch center supporting structure the utility model relates to bridge erection technology
Dynamic device.
Background technique
In the erection construction of steel pipe arch bridge, encounters across when the construction of existing major railway hub yard, face many
Technical difficulty, arch rib and construction weight are big, and installation accuracy requires high, lifting spatial altitude requirement height, but cannot use
Large-scale hoisting machinery equipment.
Existing steel pipe arch bridge often uses installation method, mainly there is non-support cable crane system, limited bracket cable hoisting, full wafer arch
Rib or the installation of limited bracket crane barge, suspension bridge type cable hoisting, rotator construction, bracket over-assemble, jack Inclined cable-stayed cantilever etc..By
Railway electrification safety regulation requires and the limitation of railway operation condition, large-scale hinge yard can not often move into large-scale hoisting machinery
Equipment, thus above-mentioned several method is difficult to carry out.
To solve the above-mentioned problems, we can will be used to support arch arch using dilatory runway is set up above yard
The branch of rib is placed on dilatory runway, is dragged to change along dilatory runway and is moved mode in place.When its arch is constructed above yard not
Need using crane, railway operation will not be had an impact, still, due to the arch of steel pipe arch bridge it is pre-fabricated after transport construction to
Scene is lifted, and arch weight is larger, the arch during transportation since center of gravity is excessively high, in addition to needing high stability
Outside supporting structure, it is also necessary to a kind of driving device.
Utility model content
The utility model provides a kind of for driving the driving device of steel tube arch bridge arch center supporting structure.
It is a kind of for driving the driving device of steel tube arch bridge arch center supporting structure, including rack, the head end of rack and end
It is provided with connection steel member, multiple roll shafts that rack is arranged at machine frame inside are supported, and pass through its end between roll shaft
Axle center column is connected using chain, is formed it into roll shaft chain, is filled bar steel plate in roll shaft chain.
By being connected to form roll shaft chain in the multiple roll shafts of machine frame inside, and bar steel plate is set inside roll shaft chain, can incite somebody to action
Arch supporting structure and the gravity laod of arch be evenly distributed on each roll shaft, have large carrying capacity, stability is good,
The rolling resistance of its roll shaft is small and can continuous rolling.
Detailed description of the invention
Fig. 1 is the vertical structure schematic diagram of the driving device.
Specific embodiment
As shown in Figure 1, this is used to drive the driving device of steel tube arch bridge arch center supporting structure, including rack (1), rack
(1) head end is provided with end connect steel member (2), and the multiple roll shafts (3) being arranged inside rack (1) are propped up
It supports, is connected, formed it into roll shaft chain (5), roll shaft chain (5) using chain (4) by the axle center column of its end between roll shaft (3)
Interior filling bar steel plate (6).By being connected to form roll shaft chain in the multiple roll shafts of machine frame inside, and bar shaped is set inside roll shaft chain
Steel plate, can by arch supporting structure and the gravity laod of arch be evenly distributed on each roll shaft, so that the driving be made to fill
Setting can be moved on rail.
In order to make the driving device adapt to the arch supporting structure of different longitudinal spans, another drive can be connected at one end
Connection steel member (2) on dynamic device.
In order to make the driving device have faster movement speed under the premise of meeting stability, in the company of rack head end
Connect steel member connection punching jack (7).
Has enough tensile strength to make the connector between two driving devices, between two neighboring connection steel member
It is connected using exquisite screw-thread steel (8).
Claims (3)
1. a kind of for driving the driving device of steel tube arch bridge arch center supporting structure, including rack, the head end of rack and end are equal
It is provided with connection steel member, it is characterised in that: multiple roll shafts that the rack is arranged at machine frame inside are supported, between roll shaft
It is connected by the axle center column of its end using chain, forms it into roll shaft chain, fill bar steel plate in roll shaft chain.
2. driving device according to claim 1, it is characterised in that: the connection steel member connection at rack head end end is worn
Heart jack, end connect the connection steel member in another driving device.
