Description
Technical field
The utility model relates to beam body pushing tow spacing equipment technical field, in particular to a kind of thrust beam limiting device.
Background technique
The current national economic development is swift and violent, the problems such as in order to solve urban congestion, crossing elimination, and saves to the full extent
About to plough, the bridge in traffic route is more and more, and in order to guarantee that existing line operates normally, current science of bridge building is adopted extensively
It is constructed with incremental launching method.In incremental launching construction, one section of nose girder can be arranged in girder front end, under the dilatory effect of jack, nose girder
And girder slowly slides forward, nose girder offset then girder can also generate offset, therefore in incremental launching construction to the limit of nose girder very
It is important.
Application No. is CN201220207400.6 to provide " a kind of thrust beam cross spacing device ", the utility model patent energy
It enough solves the problems, such as limit accuracy, but does not mention the disassembly problem after pulley abrasion, while also not illustrating limiting device
Fixation problem, during bridge incremental launching, limiting device bears very big power, and thus pulley is also highly susceptible to wear.Cause
This, proposes that the disassembly of pulley may be implemented in a kind of thrust beam limiting device, the device, and preferably fix limiting device, together
When it is relatively simple for structure.
Summary of the invention
In order to solve, the bridge incremental launching construction limiting device prior art is not directed to pulley disassembly and limiting device is fixed not
Foot, the utility model provide a kind of thrust beam limiting device, which is easily achieved pulley and dismantles, while limiting device
Fixed effect is preferable, relatively simple for structure.
The utility model uses following technical scheme:
A kind of thrust beam limiting device by steel nose girder, slipway beam, limit steel plate, reinforces steel plate, I-steel, transverse distribution
Beam, pulley, slipway beam upper plate, steel shaft pin, anchor point, rotating steel shaft, front shroud, bolt composition.Pacify on the top of transverse distribution beam
Slipway beam is set, is attached by bolt therebetween, the top of slipway beam disposes steel nose girder, and limit steel plate is pressed with steel plate is reinforced
Book mode shown in the drawings welds together as directed, reinforces being welded on one also by the mode of welding between steel plate and I-steel
It rises, I-steel is attached with transverse distribution beam by bolt.
Preferably, described front shroud one end and limit steel plate between be attached by rotating steel shaft, the front shroud other end with
It is attached between limit steel plate by bolt.
Preferably, the pulley is one group by the series connection of steel shaft pin, and entirety is led between limit steel plate at anchor point
Bolt is crossed to be attached.
Preferably, the limit steel plate runs through slipway beam upper plate, is attached by bolt.
The beneficial effects of the utility model are: (1) pulley is an entirety by the series connection of steel shaft pin, it is fixed on limit steel plate
On, while limiting that one end between steel plate and front shroud is hinged, and one end is bolted, convenient for the disassembly of pulley.(2) steel is limited
Plate runs through slipway beam upper plate, is bolted between slipway beam, the fixed effect of limiting device can be made more preferable.(3)
The setting of front shroud can reduce abrasion of the bridge incremental launching in the process to limit steel plate.
Detailed description of the invention

Attached drawing 2 is the sectional view of the utility model.
Attached drawing 3 is the limit sheet steel sections side longitudinal sectional view of the utility model.
Attached drawing 4 is the limit steel plate horizontal cross of the utility model.
Wherein, 1 steel nose girder, 2 slipway beams, 3 limit steel plates, 4 reinforcement steel plates, 5 I-steel, 6 transverse distribution beams, 7 pulleys, 8
Slipway beam upper plate, 9 steel shaft pins, 10 anchor points, 11 rotating steel shafts, 12 front shrouds, 13 bolts.
Specific embodiment
With reference to the accompanying drawings, a kind of thrust beam limiting device, mainly by steel nose girder 1, slipway beam 2 limits steel plate 3, reinforces steel plate
4, I-steel 5, transverse distribution beam 6, pulley 7, slipway beam upper plate 8, steel shaft pin 9, anchor point 10, rotating steel shaft 11, front shroud 12,
Bolt 13 forms.
During bridge incremental launching construction, steel nose girder 1 is located at the top of slipway beam 2, and slipway beam 2 is located at transverse distribution beam 6
Top is attached by bolt.
Steel nose girder 1 is Steel Truss Beam, is the interim supplementary structure loaded on beam front end or rear end, it is ensured that beam is when moving
Longitudinal stability against overturning, while the cantilevered length of beam can be reduced to reduce mount stress, height is less than ridge purlin,
Root edge and box beam bottom should be in the same plane.Slipway beam 2 girder in place after can be carried out removing, while replacing formal branch
Seat.
One end is connected by rotating steel shaft 11 between limit steel plate 3 and front shroud 12, and the other end is attached by bolt 13,
Pulley 7 is an entirety by the series connection of steel shaft pin 9, is attached with limit steel plate 3 by bolt at anchor point 10, according to cunning
The degree of wear of wheel 7 can carry out dismounting and change to pulley 7 and this entirety of steel shaft pin 9.
It limits steel plate 3 and runs through slipway beam upper plate 8, be attached by bolt.
Steel plate 3 is limited with a thickness of 20mm, reinforces steel plate 4 with a thickness of 20mm, is connected by welding therebetween
It connects, I-steel 5 uses Two bors d's oeuveres mode, and specification 40a is connected by welding between I-steel 5 and reinforcement steel plate 4
It connects, lower part and the transverse distribution beam 6 of I-steel 5 are bolted.
Certainly, the above description is not intended to limit the present invention, and those skilled in the art are practical new at this
The variations, modifications, additions or substitutions made in the essential scope of type, should also belong to the protection scope of the utility model.
