Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction equipment, and in particular relates to a sliding shoe for transverse movement of a railway box girder. Background Art

[0002] With the rapid development of the economy and society, more and more high-speed railways have appeared in my country, and there are more and more steel truss swivel bridges across or near high-speed railways. In order to reduce the occupation of land, such bridges are relatively close to high-speed railways, especially bridges in the same direction as the high-speed railway line, which are closer to the high-speed railway line. During the construction of this type of bridge, it will be affected by the high-speed passenger trains passing at high speed, and the construction process has to be interrupted. In addition, the proximity to the high-speed railway will also affect the safety of high-speed railway operation. When constructing and installing steel box girders, they need to be assembled at the construction site, and equipment and personnel will stay next to the high-speed railway for a long time. Affected by the passing high-speed railway, the installation and construction efficiency of the steel box girder is low, and there is a great safety risk.

[0003] In the existing related technology, the box girder can be assembled on the side of the bridge to be constructed through a slideway, and then slid into place by lateral movement. In this way, the box girder can be as far away from the existing high-speed railway as possible during the assembly process. In the current technology, the sliding shoe generally slides horizontally, and the bottom full-frame needs to be removed before sliding. In this way, there is a lack of protection during the construction process. Once the box girder becomes unstable, it is easy to damage the existing high-speed railway.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art. The utility model provides a sliding shoe for transverse movement of a railway box girder.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sliding shoe for transverse movement of a railway box girder comprises two shoe parts hinged to each other, wherein the shoe parts include:

[0012] A through hole is provided in the middle of the shoe along its length direction for the traction cable to pass through.

[0013] Preferably, a plurality of evenly distributed ribs are provided on both sides of the shoe.

[0014] Preferably, guide plates are provided on both sides of the bottom plate, the length of the guide plates is matched with the length of the boot, and the spacing between the two guide plates is matched with the width of the slideway.

[0015] Preferably, the upper surface of the slideway is an inclined surface, and the end of the inclined surface corresponding to the sliding end point of the sliding shoe is inclined upward.

[0016] Preferably, the perforations are waist-shaped holes extending longitudinally.

[0017] Preferably, the guide plate is provided with a plurality of screw holes evenly distributed along its length direction, and the positioning bolts pass through the screw holes and then press against the slideway to fix the slide shoe.

There are a plurality of fixed columns, and the plurality of fixed columns are evenly distributed around the continuous jack 9.

[0033] The bottom plate 7 and the top plate 2 are spaced apart in the longitudinal direction, and one end of the bottom plate 7 extends upward to form an inclined surface corresponding to the inclined slide 13, so that the box girder can be lifted when sliding on the slide 13. Two double-piece steel plates 1 are fixed between the top plate 2 and the bottom plate 7, and the lower side of the double-piece steel plate 1 is adapted to the inclination angle of the bottom plate 7, thereby ensuring the supporting capacity of the sliding shoe. End plates 3 are fixed at both ends of the shoe, and hinge plates 4 are provided on the adjacent end plates 3 of the two shoe parts by welding, so that the two shoe parts can be hinged through a hinge shaft.

A U-shaped hinge seat is provided on the top of the supporting short section, and the U-shaped hinge seat is hinged to the slideway 13 through a hinge shaft.

[0039] The through hole 10 is a waist-shaped hole extending in the longitudinal direction, which can make way for the longitudinal displacement of the traction cable 11 when the sliding shoe slides.

[0040] In an optional embodiment, the guide plate 5 is provided with a plurality of screw holes 6 evenly distributed along its length direction. After the positioning bolts pass through the screw holes 6, they are tightened against the slideway 13 to fix the sliding shoe. Specifically, the sliding shoe is locked after the box beam is spliced ​​or the box beam is moved horizontally into place to ensure the stability of the sliding shoe.

[0041] The end of the sliding shoe away from the sliding end of the sliding shoe is provided with a driving mechanism connected by a push plate, and the driving mechanism is a continuous jack 9.
