Locking device for limiting guide pipe on weight limiting frame

Abstract

The invention provides a locking device for a limiting guide pipe on a weight limiting frame, and the locking device comprises a cross-brace angle steel and the limiting guide pipe vertically connected with the cross-brace angle steel through a bolt, wherein a locking base is vertically arranged on one side of the cross-brace angle steel, a hook is arranged on the surface of the locking base, a hook groove of the hook is hung on the side edge of the cross-brace angle steel to fix the locking base, strip-shaped holes are formed in the two sides of the limiting guide pipe on the locking base, hook bolts are arranged in the strip-shaped holes, through holes are also formed in the two sides of the limiting guide pipe at the lower end of the locking base, U-shaped bolts are arranged in the through holes, and the U-shaped bolts are clamped on the limiting guide pipe. The locking device for limiting the guide pipe is arranged at the connecting position of the original limiting frame, can playa role of safety locking without damaging the original structure, is particularly suitable for safe reinforcement of railway contact network engineering or construction and installation of newly-built railways, is convenient to install and adjust, saves time and labor, improves the overhauling efficiency, and is beneficial to shortening the construction and overhauling time and saving the operation and maintenance cost.

Description

technical field [0001] The invention relates to a fastener for a weight limiting guide tube, in particular to a locking device for a limit guide tube on a weight limit frame. Background technique [0002] The railway catenary pendant is used to apply rated tension to the catenary cable and the contact line to ensure the pantograph to take power smoothly. The anchor compensation device is mainly composed of a pulley compensation device, a ratchet compensation device, a spring compensation device, a weight and a weight The main function of the weight limit frame is to limit the swing of the weight string to ensure that the weight string automatically adjusts the slack of the clues with the temperature change under the action of its own gravity to be basically constant. At present, my country's high-speed railway has exceeded 250km / h, and the Beijing-Shanghai high-speed railway has achieved an operating speed of 350km / h. There are two types of restricting conduit bases on the ...

AI Technical Summary

Problems solved by technology

There are two types of restricting conduit bases on the weight restricting frame, Type A and Type B. Type A is the embedded type, and Type B is the fixed type (bracket type), but whether it is the embedded type or the fixed type, it has at least An upper bracket, the bracket is generally a cross bracing angle steel, and the connection between the bracket and the restricting conduit is connected by bolts, and no anti-loosening measures are taken. The vibration caused by the high-speed operation of the train and the vibration caused by environmental factors such as strong winds will cause the bolts to loosen. If it is loose or even falls off, it may cause the restricting tube to fall to the track, causing a major accident in driving
