Firstly, inserting the inner sleeve into the pipe section to enable the clamping plate to be clamped with the pipe section, then inserting the cap head into an inner hole of the inner sleeve, and enabling the convex strip to be extruded to generate deformation, so that the inner sleeve tightly presses the inner wall of the pipe section to realize the fixed installation of the inner sleeve; due to the design, the inner sleeve is not easy to fall off, so that the overhauling strength is reduced.
Description
Technical Field
The utility model relates to a high-speed rail power equipment technical field specifically is an electronic railway contact net cantilever system anticreep pipe cap.
Background
The contact wire of high-speed railway contact net is used for the high-speed railway to provide electric power, and the contact wire still is equipped with the bracing piece through fastener fixed mounting on the tubular profile on the high-speed railway line frame between the tubular profile, also connects through the fastener, and the general cover of tubular profile tip is equipped with the pipe cap to prevent that the fastener is not hard up roll-off tubular profile. The traditional pipe cap is easy to deform and fall off after being used for a long time, so that the overhauling strength is increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that a pipe section pipe cap on a traditional high-speed rail line frame is easy to deform and fall off is solved.
The utility model provides an electronic railway contact net cantilever system anticreep pipe cap installs in the tip of the flat cantilever of electronic railway cantilever system, oblique cantilever and registration arm, include:
the inner sleeve is inserted into a pipe profile used by the wrist arm pipe and the positioning pipe, the outer end part of the inner sleeve is provided with a clamping plate for clamping the outer edge of the pipe profile, and the inner end part of the inner sleeve is provided with a convex strip positioned on the inner wall of the inner sleeve;
and the cap head is inserted in the inner hole of the inner sleeve and is clamped with the raised line.
Firstly, inserting the inner sleeve into the pipe section to enable the clamping plate to be clamped with the pipe section, then inserting the cap head into an inner hole of the inner sleeve, and enabling the convex strip to be extruded to generate deformation, so that the inner sleeve tightly presses the inner wall of the pipe section to realize the fixed installation of the inner sleeve; due to the design, the inner sleeve is not easy to fall off, so that the overhauling strength is reduced.
Furthermore, a plurality of uniformly distributed notches are formed in the inner end portion of the inner sleeve, and the notches penetrate through the convex strips. The setting of notch makes the sand grip change easily and produces deformation.
Furthermore, an annular groove is formed in the outer wall of the inner sleeve, and the groove is located between the raised line and the clamping plate and close to the raised line. The arrangement of the groove reduces the wall thickness of the groove, which is convenient for the installation of the inner sleeve and the clamping connection of the cap head and the inner sleeve.
Furthermore, the cap head is provided with a clamping groove for clamping the outer wall of the wrist arm tube or the positioning tube, the groove wall of the clamping groove is in threaded connection with the inner sleeve, and one end of the cap head, which is provided with the clamping groove, is also provided with a regular hexagon concave table. The inner sleeve and the cap head are connected with the pipe profile through the clamping groove in a clamping mode, and the clamping groove is connected with the inner sleeve in a threaded mode, so that the pipe profile is firmer and is not easy to fall off; the arrangement of the concave platform is convenient for the operation of the external hexagonal wrench.
