Abstract
The utility model is specially a kind of D type just traversing door frame of beam, solve existing D type just beam adopt a dead lift to exist to waste time and energy and the lower problem of safety factor.Comprise two i iron girders be arranged in parallel, the two ends, left and right of i iron girder are all hinged with the support post rotated inside it, connected i iron crossbeam is provided with between two i iron end of main beams, and i iron girder is provided with slip coaster body thereon, in the middle part of coaster body, lower end is provided with and its one and postive stop baffle between two i iron girders, coaster body is provided with bearing pin, bearing pin is hung with jack.The utility model reasonable in design is reliable, while reducing labor intensity, convenient to operation, effectively improves efficiency of construction, and has stopped the phenomenon that potential safety hazard occurs, and has simple, the easy to process and advantage that cost is low of structure.
Description
Technical field
The utility model relates to construction of railways Traverse Displacement Unit, is specially a kind of D type just traversing door frame of beam.
Background technology
When highway undercrossing tunnel need build overpass bridge or increase on both wired build (reconstruction) other building time, for not affecting railway normal operation, and just wire-wound capable infeasible or uneconomical time, circuit is carried out built on stilts reinforcing by normal employing D type just beam, carry out open cut or jacking construction again, to complete bridge construction.
But during existent railway implementation, often need traversing D type just beam on the line, tradition adopts a dead lift, and use manually more, expenses of labour is higher, and construction effect is low, and safety factor is lower.
Summary of the invention
The utility model in order to solve existing D type just beam adopt a dead lift to exist to waste time and energy and the lower problem of safety factor, provide a kind of D type just traversing door frame of beam.
The utility model adopts following technical scheme to realize: D type is the traversing door frame of beam just, comprise two i iron girders be arranged in parallel, the two ends, left and right of i iron girder are all hinged with the support post rotated inside it, connected i iron crossbeam is provided with between two i iron end of main beams, and i iron girder is provided with slip coaster body thereon, in the middle part of coaster body, lower end is provided with and its one and postive stop baffle between two i iron girders, coaster body is provided with bearing pin, bearing pin is hung with jack.
When to D type, just beam is traversing, set up traversing door frame, subsequently by D type just beam be transported to below traversing door frame, sling by jack, realized traversing under the effect of coaster body, when traversing to assigned address, loosen jack, fall D type just beam, complete the traversing door frame of traversing rear dismounting, overcome existing D type just beam adopt a dead lift to exist to waste time and energy and the lower problem of safety factor.
The utility model reasonable in design is reliable, while reducing labor intensity, convenient to operation, effectively improves efficiency of construction, and has stopped the phenomenon that potential safety hazard occurs, and has simple, the easy to process and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-i iron girder, 2-support post, 3-i beam crossbeam, 4-coaster body, 5-postive stop baffle, 6-bearing pin.
Detailed description of the invention
D type is the traversing door frame of beam just, comprise two i iron girders 1 be arranged in parallel, the two ends, left and right of i iron girder 1 are all hinged with the support post 2 rotated inside it, connected i iron crossbeam 3 is provided with between two i iron girder 1 ends, and i iron girder 1 is provided with slip coaster body 4 thereon, in the middle part of coaster body 4, lower end is provided with and its one and postive stop baffle 5 between two i iron girders 1, coaster body 4 is provided with bearing pin 6, bearing pin 6 is hung with jack.
In specific implementation process, be all bolted between each parts of the D type just traversing door frame of beam, for convenience detach; And the setting of postive stop baffle 5, be to prevent coaster body 4 to turn on one's side the problem caused casualties.
