Abstract
Description
Technical Field
[0001] The invention relates to an integral hanging string and a hanging string wire clamp for a contact network, belonging to the technical field of flexible suspension equipment for an electrified railway contact network system. Background Art
[0002] With the increasing development of electrified railway construction and technological progress, the technical requirements for flexible suspension equipment of the overhead contact system, especially the integral suspension string and the suspension string clamp, are becoming increasingly higher, because it is one of the more critical components in the overhead contact system of the electrified railway, and it is directly related to the operation safety and quality of the electrified railway. In the known technology, in the electrified railway contact network system, there are numerous integral suspension strings between the copper alloy contact wire and the copper alloy stranded wire load-bearing cable to ensure the parallelism between the contact wire and the rail surface. The existing integral suspension strings and suspension string clamps mainly adopt a bolt connection structure, which is connected by a heart-shaped protective ring and a U-shaped hanging ring; the other type is a suspension string clamp with a boltless structure that is cast, and the guide wire and the suspension string clamp are connected by a crimping terminal connection structure, and are mainly fastened by a threaded pair. The structure is complex, the installation is cumbersome, and it is greatly affected by the operating level of the installer. A large tightening torque during installation will cause damage to the clamp body. If the tightening torque is too small, it is easy to cause the bolts to loosen after a long time of use, especially at the joint of the anchor section, which will cause the contact line or the load-bearing cable to be off the line, posing a safety hazard. For example, Chinese patent application publication number CN101445066 discloses a current-carrying adjustable body suspension string, which is a load-bearing cable aluminum suspension string clamp connected to the aluminum-clad steel aluminum stranded wire load-bearing cable, and the contact line suspension string clamp is connected to the copper-silver alloy contact wire; the load-bearing cable aluminum suspension string clamp and the contact line suspension string clamp are left-right symmetrical structures, and the structural parts are locked by locking bolts, and the copper-magnesium alloy suspension string has copper alloy connecting wire clamps and copper-aluminum transition connecting wire clamps at both ends, and the copper alloy connecting wire clamp passes through the contact line suspension string clamp and is fixed by a wire pressing tube; but due to the limitations of its product structure, the bolts will become loose over time during actual operation, and there is a potential problem of causing bow net failure, and its structural design needs to be further improved and enhanced.
