Abstract
The utility model discloses an eccentric formula activity heart rail is with connecting iron belongs to railway switch technical field, connects the iron and turns shape for whole cast song, and the connecting rod is connected at the bottom plate right angle, and the pull rod is connected at the connecting rod right angle, is equipped with even board on the bottom plate, even board end is equipped with through-hole one, and the end of pull rod is equipped with through-hole two, is equipped with two through-holes three on the bottom plate respectively. When lines with different gauges are crossed, the movable center rail can be effectively connected with a switching system, the risks of welding or deformation and the like are avoided, the driving safety can be ensured, the structure is simple, and the maintenance is convenient.
Description
Technical Field
The utility model relates to an eccentric formula activity heart rail is with connecting iron belongs to railway switch technical field.
Background
When lines with different gauges are crossed, the centers of two obtuse frog shift, which causes the connection between the point switch and the movable point rail to be eccentric, and brings great trouble to on-site trial laying work. The existing construction method has two solutions, one is that the fitting is cut according to the actual size on site, and then the fitting is welded on a joint iron for a standard turnout according to the installation position, so that the possibility of welding exists; and secondly, the switch pull rod for the electric service is heated and bent in a factory to realize the connection with the connector iron for the standard turnout, and the possibility of deformation of the bent point after stress exists. Both of the two prior proposals are easy to cause the failure of the switch device during the use process of the turnout.
Disclosure of Invention
In order to overcome the above-mentioned not enough, the utility model provides an eccentric formula activity heart is joint iron for rail, this eccentric formula activity heart can increase the connection member with eccentric formula electricity affairs pull rod on the basis of normal switch with joint iron, realize the connection of activity heart rail and electricity affairs goat pull rod.
The utility model provides a technical scheme that its technical problem adopted is: eccentric formula activity heart is its structure of joint iron for rail: the joint iron is in a crank shape of integral casting, the connecting rod is connected with the bottom plate at a right angle, the pull rod is connected with the connecting rod at a right angle, the connecting plate is arranged on the bottom plate, the first through hole is formed in the end of the connecting plate, the second through hole is formed in the end of the pull rod, and the third through hole is formed in the bottom plate.
The utility model has the advantages that: when lines with different gauges are crossed, the movable center rail can be effectively connected with a switching system, the risks of welding or deformation and the like are avoided, the driving safety can be ensured, the structure is simple, and the maintenance is convenient.
Drawings
Fig. 1 is a schematic structural view of the joint iron for the eccentric movable point rail of the present invention.
Fig. 2 is a schematic view of the top view structure of the joint iron for the eccentric movable point rail of the present invention.
Fig. 3 is a schematic view of the connection of the joint iron for the eccentric movable point rail of the present invention.
In the figure, the device comprises a base plate 1, a base plate 2, a connecting plate 3, through holes I and II, a connecting rod 5, a pull rod 6, through holes II and II, through holes III and 8, a work pull rod 9, an electric work pull rod 10, a joint iron 11, a blunt fork wing rail 12 and a movable center rail.
Detailed Description
As shown in fig. 1-2, the joint iron for eccentric movable center rail has the following structure: the joint iron 10 is a crank shape integrally cast, the connecting rod 4 is connected with the bottom plate 1 at a right angle, the pull rod 5 is connected with the connecting rod 4 at a right angle, the connecting plate 2 is arranged on the bottom plate 1, the end of the connecting plate 2 is provided with a first through hole 3, the end of the pull rod 5 is provided with a second through hole 6, and the bottom plate 1 is respectively provided with two third through holes 7.
When in use, as shown in fig. 3, the bottom plate 1 of the joint iron 10 is connected with the movable core rail 12 through the through hole three 7 by bolts, the through hole one 3 on the connecting plate 2 is hinged with the engineering pull rod 8, and the other end of the engineering pull rod 8 is hinged with the movable core rail at the other side; the through hole II on the pull rod 5 is hinged with an electric affair pull rod 9, and the electric affair pull rod 9 is hinged with opposite joint irons.
The acting force of the switch machine acts on the electric traction rod 5 to drive the movable point rail 2 to act, and the close contact with the blunt fork wing rail 11 is realized. Meanwhile, the switch force is transmitted to the engineering pull rod, the opposite movable center rail is pulled to be separated from the blunt fork wing rail, and the width of the wheel edge groove is enough to ensure that the wheel passes through.
