The lower end of the vertical plate is bent towards one side far away from the steel rail, namely towards the outer side, and extends to the outer side of the steel rail foot to form a protective plate positioned on the outer side of the steel rail; the lower end of the protective plate is horizontally bent towards one side far away from the steel rail foot to form a mounting plate; the flat plate, the vertical plate, the protective plate and the mounting plate jointly form a double-n-shaped buckling and pressing element; balance bolts are mounted on the four mounting plates; a puller bolt is installed on the protective plate, and the end of the puller bolt is in direct contact with the steel rail. According to the utility model, the phenomenon that the steel rail laterally moves or turns over in the using process of the steel rail is avoided, and the safety controllability and the working efficiency of on-site construction are improved.

Description

Technical Field

[0001] The utility model relates to a rail laying stabilizing device, in particular to a device for preventing the rail from lateral displacement and overturning, which is suitable for the construction of mechanical equipment such as a bridge erecting machine or a mobile formwork bridge erecting machine. Background Art

[0002] During the construction process of mechanical equipment such as bridge-building machines or mobile formwork bridge-building machines, after the rails are laid, the conventional fixing method is relatively complicated, time-consuming and labor-intensive. If they are not fixed or not fixed firmly, the rails may tip over, which will not only wear out the prefabricated or installed components, but also require manual work to straighten the tipped rails, which is labor-intensive and time-consuming, affecting the construction period and increasing construction costs. Summary of the invention

[0003] The utility model aims to provide a device for preventing rail lateral displacement and rollover, so as to prevent the rail from lateral displacement or rollover during use, thereby improving the safety controllability and work efficiency of on-site construction.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for preventing rail lateral displacement and rollover, the device comprises a clamping element clamped on the rail, the clamping element comprises a flat plate pressed against the top of the rail, the four corners of the flat plate are bent vertically downward to form vertical plates located on both sides of the rail, and there is a spacing between the vertical plates and the top plate of the rail; the lower end of the vertical plate is bent toward the side away from the rail, that is, outwardly and extends to the outside of the rail foot to form a guard plate located on the outside of the rail, and the guard plate is inclined; the lower end of the guard plate is bent horizontally toward the side away from the rail foot to form a mounting plate for mounting a balancing bolt; the flat plate, the vertical plate, the guard plate and the mounting plate together constitute a clamping element in the shape of a double "X"; balancing bolts for ensuring the balance of the clamping element are installed on the four mounting plates; a tightening bolt for preventing the rail from overturning is installed on the guard plate, and the end of the tightening bolt is in direct contact with the rail.

[0006] The utility model provides a device for preventing rail lateral displacement and rollover, which adopts the above technical scheme to avoid the occurrence of rail lateral displacement or rollover during the use of the rail, thereby improving the safety controllability and work efficiency of on-site construction.

[0010] The utility model is described in detail with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 , Figure 2 As shown, a device for preventing rail lateral displacement and rollover is provided, the device having a clamping element clamped on the rail 1, the clamping element having a flat plate 2 pressed against the top of the rail, the four corners of the flat plate 2 are bent vertically downward to form vertical plates 3 located on both sides of the rail, and there is a spacing between the vertical plates 3 and the top plate of the rail; the lower end of the vertical plate 3 is bent toward the side away from the rail, that is, outwardly and extends to the outside of the rail foot to form a guard plate 4 located on the outside of the rail, and the guard plate 4 is inclined; the lower end of the guard plate 4 is bent horizontally toward the side away from the rail foot to form a mounting plate 5 for mounting a balancing bolt 6; the flat plate, the vertical plate, the guard plate and the mounting plate together constitute a clamping element in the shape of a double "X"; the four mounting plates are all installed with balancing bolts 6 for ensuring the balance of the clamping element; the guard plate is installed with a tightening bolt 7 for preventing the rail from overturning, and the end of the tightening bolt is in direct contact with the rail.

[0012] During bridge construction, large equipment such as bridge erection machines or mobile formwork bridge-building machines are generally used. These equipment need to be moved forward with the help of rails during use. As shown in the figure below, if the rails used to move the equipment forward are not fixed or not fixed firmly, the rails may shift sideways or overturn.

[0013] At this time, we only need to buckle the device we invented on the rail to ensure the stability of the rail and prevent lateral shifting or overturning.
