Abstract
Railway switch tongue bolt sleeve, relates to railway equipment maintenance technique field, particularly belongs to a kind of railway switch tongue bolt sleeve being applicable to railway switch tongue.It is characterized in that having bolt sleeve body (1), described bolt sleeve body is the steel pipe of the C-shaped structure of a section, and steel pipe length is 22 millimeters, and the distance of C type opening (2) is 20 millimeters, and this body diameter of bolt sleeve matches with tongue bolt hole.The utility model has the safety guarantee improving railway transportation and the good effect saving railway maintenance cost.
Description
Technical Field
The utility model relates to a railway equipment maintenance technical field especially belongs to a railway switch tongue bolt sleeve pipe suitable for railway switch tongue.
Background
The railway turnout is overloaded and operated, so that the phenomenon of serious turnout abrasion is caused, particularly, after bolt holes at the heel end of a turnout switch rail are enlarged, bolts are not closely matched with the bolt holes, the bolts can not normally play a fixing role, when a train passes through the turnout switch rail, the consequences such as switch rail jumping and even off-line are easily caused, and potential safety hazards are brought to railway transportation. The solution currently used is to replace the switch rails, but this method causes a considerable increase in the line maintenance costs, is neither economical nor solves the fundamental problem.
Disclosure of Invention
An object of the utility model is to provide a railway switch tongue bolt sleeve to reach reinforcing bolt intensity, eliminate railway transportation potential safety hazard, practice thrift cost of maintenance's purpose.
The utility model provides a railway switch tongue bolt sleeve, a serial communication port has the bolt sleeve body, the bolt sleeve body be a steel pipe that the cross-section is C type structure, steel pipe length is 22 millimeters, C type open-ended distance is 20 millimeters, this external diameter of bolt sleeve cooperatees with the tongue bolt hole.
The utility model discloses a railway switch tongue bolt sleeve pipe, the adoption has the certain wall thickness that has of seam width, and in addition, bolt sleeve pipe body can freely expand and reduce. The strength of the bolt is enhanced, and the potential safety hazard of the switch rail caused by the overlarge abrasion of the bolt hole is eliminated; meanwhile, the switch rail can be continuously used without replacement, and the positive effects of improving the safety guarantee of railway transportation and saving the maintenance cost of the railway are achieved.
Drawings
The accompanying drawings further disclose embodiments of the present invention. Wherein,
FIG. 1: the structure of the utility model is schematically shown.
Detailed Description
As shown in fig. 1, the utility model provides a railway switch tongue bolt sleeve pipe has bolt sleeve pipe body 1, bolt sleeve pipe body be the steel pipe of a C type structure, steel pipe length is 22 millimeters, C type opening 2's distance is 20 millimeters, bolt sleeve pipe body is located the tongue bolt hole.
The bolt sleeve body has a certain wall thickness, and the railway turnout tongue bolt sleeve with the proper wall thickness can be selected and used according to the abrasion of the bolt hole. In addition, because of the C-shaped pipe, the bolt sleeve body can be freely expanded or contracted when stressed.
When in use, the utility model is placed in the bolt hole at the heel end of the switch rail, and plays a role of reinforcement together with the reducing bolt, thereby enhancing the strength of the bolt, eliminating the hidden trouble of the switch rail caused by the play due to the over-large abrasion of the bolt hole, and improving the safety guarantee of railway transportation; and simultaneously, the utility model discloses an use for the switch rail need not to change and also can continue to use, great saving railway cost of maintenance.
Claims (1)
