Abstract

The utility model provides an insulated and lengthened tie rod for a railway switch. An insulator is arranged at the middle of a metal pull rod, both ends of the pull rod are sheathed with a plurality of groups of inner-hook type clamping tools, both ends of each group of clamping tools are provided with fixing nuts which form screw-thread fit connection with the pull rod, and the clamping tools can be fixed to steel rails. The middle of each clamping tool is also provided with a screw-thread connecting sleeve pipe which forms screw-thread connection with the pull rod, so the distance among the clamping tools can be adjusted. The structure of the inner-hook type clamping tools can make the steel rails of each key position in a frog and double type slip switch combined into a whole so as to ensure that each steel rail in the switch can have the functions of automatic control, mutual control and other control under the impact of trains and have good ensuring function for the gauge size of each part, and the insulated and lengthened tie rod makes up the defect of difficult redirection of the double type slip switch by the over placement of the steel rails. The utility model has the characteristics of simple structure, easy installation, compact appearance, high insulating performance, safety, reliability, etc.

Description

Railway switch insulation lengthening gage tie bar

Technical field

The utility model is to existing railway switch gage tie bar structural development, and a kind of railway switch insulation lengthening gage tie bar is provided, and belongs to railway switch special part technical field.

Background technology

The related gage tie bar of the utility model is the crucial reinforcement feature that guarantees that the railway switch size does not change, and guarantees the stable enforcement of train high-speed secure, and the minimizing accident takes place.But existing gage tie bar is unitary construction, can only be installed on adjacent two one steel rails variation of control rail size.Be provided with at double slip switch complex structure, the rail of railway that compactness, gauge are difficult for keeping, drop under the frequent situation man-hour, existing gage tie bar is owing to be unitary construction, do not connect mutually, put too much, there is not globality, therefore, the gauge size of track switch is difficult to just protecting, and has jeopardized the traffic safety of railway.

Summary of the invention

The utility model provides a kind of railway switch insulation lengthening gage tie bar, has overcome existing monomer-type gage tie bar and do not connect the shortcoming of globality difference mutually in using in railway frog and double slip switch.

Technical solution of the present utility model is as follows:

The middle part of metal pull bar is an insulator, and two ends are set with some groups of in-ward hook jigs, and the two ends of every group of jig are provided with the confinement nut and pull bar formation rib-loop is connected, and jig can be confined on rail;

Also be provided with screw joint casing at the middle part of jig and be connected, can adjust the distance between the jig with pull rod screw.

The dop of described in-ward hook jig can be made geometric configuratioies such as square, triangle according to the shape at positions such as the stock rail in the railway tongue, tongue butt, track switch axis.

Good effect of the present utility model is: organizing in-ward hook jig structure can link into an integrated entity each key position rail in railway frog and the double slip switch more, guarantee that each strand rail in the track switch can both impact the effect of being conigenous control, cross complaint, its control that issues at train, each part mentioned above gauge size there is guarantee effect preferably, has remedied track switch invar rail and put the defective that is difficult for changing its course more.Characteristics such as that this device has is simple in structure, be easy to install, outward appearance is succinct, insulativity is high, safe and reliable.

The specific embodiment

According to shown in Figure 1, be provided with insulator 2 at the middle part of metal pull bar 1, two (also can be decided according to the actual requirements) in-ward hook jigs 3 are sleeved on the both sides of pull bar 1, the two ends of jig 3 are provided with confinement nut 4 and are connected with pull bar 1 formation rib-loop, can adjust the spacing of jig 3 by swivel nut 4, with the rail fastening.

Also be provided with screw joint casing 5 with reference to Fig. 2 at the middle part of jig 3 and be threaded, can adjust the distance between the jig 3 with pull bar 1.

Claims

1, a kind of railway switch insulation lengthening gage tie bar, it is characterized in that: the middle part of metal pull bar is an insulator, and two ends are set with some groups of in-ward hook jigs, and the two ends of every group of jig are provided with the confinement nut and pull bar formation rib-loop is connected.

2, lengthening gage tie bar according to claim 1 is characterized in that: also be provided with screw joint casing at the middle part of jig and be connected with pull rod screw.
