Description
Technical field
The utility model relates to railway equipment maintenance technique field, particularly belongs to a kind of railway switch tongue bolt sleeve being applicable to railway switch tongue.
Background technology
Railway switch overload operation, track switch is caused to wear away serious phenomenon, especially point tongue heel end bolt hole becomes greatly, bolt and bolt hole coincide not close, bolt just normally cannot play fixation, when train is by point tongue, easily cause tongue to be beated, the even consequence such as off-line, bring potential safety hazard to railway transportation.Solution conventional at present changes tongue, but this method can cause increasing substantially of line maintenance expense, both uneconomical, can not solve root problem again.
Summary of the invention
The purpose of this utility model is to provide a kind of railway switch tongue bolt sleeve, to reach the object strengthening bolt strength, eliminate safety of railway traffic hidden danger, save maintenance cost.
A kind of railway switch tongue bolt sleeve provided by the utility model, it is characterized in that, there is bolt sleeve body, described bolt sleeve body is the steel pipe of the C-shaped structure of a section, steel pipe length is 22 millimeters, the distance of C type opening is 20 millimeters, and this body diameter of bolt sleeve matches with tongue bolt hole.
Railway switch tongue bolt sleeve disclosed in the utility model, adopts and has that seam is wide has certain wall thickness, and in addition, bolt sleeve body can free-extension and reducing.Enhance the intensity of bolt, eliminate tongue causes play potential safety hazard because bolt hole abrasion are excessive; Meanwhile, tongue need not be changed and also can continue to use, there is the safety guarantee improving railway transportation and the good effect saving railway maintenance cost.
Accompanying drawing explanation
Accompanying drawing part further discloses embodiment of the present utility model.Wherein,
Fig. 1: structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, railway switch tongue bolt sleeve provided by the utility model, has bolt sleeve body 1, described bolt sleeve body is the steel pipe of a C type structure, steel pipe length is 22 millimeters, and the distance of C type opening 2 is 20 millimeters, and bolt sleeve body is positioned at tongue bolt hole.
Above-mentioned bolt sleeve body has certain wall thickness, can according to the abrasion size of bolt hole, the railway switch tongue bolt sleeve of choice for use suitable wall thickness.In addition, owing to being C type pipe, time stressed, bolt sleeve body can free-extension or reduce.
During use, the utility model is placed in the bolt hole of heel of switch rail, jointly plays reinforcement effect with reducing bolt, enhance the intensity of bolt, eliminate tongue causes play hidden danger because bolt hole abrasion are excessive, improve the safety guarantee of railway transportation; Meanwhile, application of the present utility model, making tongue also can continue to use without the need to changing, having saved railway maintenance cost greatly.
