Description

Technical Field

[0001] The utility model relates to the technical field of integral suspension strings, in particular to a die-forged loop type integral suspension string. Background Art

[0002] The overhead catenary system of high-speed railways is a device to ensure the safety of railway transportation. The integral suspension string is one of the important components of the catenary system. It is installed between the carrier cable and the contact wire, used to increase the contact suspension points, improve the sag and elasticity uniformity of the contact wire, adjust the structural height of the contact suspension, and play a certain role in bearing capacity and current-carrying. When the pantograph passes, the contact wire continuously rises and vibrates, and the integral suspension string also rises and bends accordingly.

[0003] The contact wire clamp body and the carrier wire clamp body of the integral suspension string are connected by a suspension string wire. The arc section of the contact loop passes through one end of the suspension string wire hole, and the arc section of the carrier loop passes through the other end of the suspension string wire hole. A heart-shaped insert ring is fixedly arranged in the suspension string wire hole, and the outer wall of the heart-shaped insert ring is circumferentially attached to the inner wall of the suspension string wire hole.

[0004] The materials commonly used for the contact loop and the carrier loop of the integral suspension string are silicon bronze stampings, and the effective thickness is only 2 mm. When the train speed increases and the line amplitude increases, cracks and even fractures are likely to occur at the contact between the loop and the heart-shaped insert ring due to frequent and severe collision wear. In addition, the silicon bronze stamping loop is prone to elastic deformation during service, and then turns into plastic deformation, resulting in a significant attenuation of the fastening torque of the connecting piece, leading to the loosening of the connection between the components of the contact wire clamp body and the carrier wire clamp body, making the operation stability of the integral suspension string worse, and thus the safe operation of the catenary system cannot be guaranteed.

[0005] In addition, the suspension string wire commonly used for the integral suspension string is JTMH10 copper alloy stranded wire. When the train speed increases and the line amplitude increases, the suspension string wire is prone to broken wires and broken strands. In order to ensure the stable and safe operation of the overhead catenary system of high-speed railways, it is necessary to improve the mechanical properties of the key stress-bearing components of the integral suspension string. And the heart-shaped insert ring is prone to collision and wear with the contact loop and the carrier loop, resulting in wear and fracture. Summary of the Utility Model

[0038] The beneficial effects of the present utility model are as follows:

[0039] (1) Most of the rings for integral suspension strings on the market are manufactured by stamping process. During the manufacturing process, the silicon bronze stamping part sheet is stamped and bent into a U-shaped structure. The stamping and bending process causes a large amount of residual stress in the obtained U-shaped ring structure, and a large number of micro-cracks are generated at the edges of the obtained rings, seriously shortening the reliability and service life of the integral suspension string. The present utility model provides a die-forged integral ring, which is integrally formed by a precision die-forging forming process. Its U-shaped bending part is a solid structure, and the ring is heat-treated to remove residual stress. The forming process does not involve stamping and bending treatment. The obtained die-forged integral ring is not prone to wear and fracture, has good reliability, and a longer service life;

[0040] (2) In the die-forged integral ring structure of the present utility model, the thickness of the tapered part gradually decreases from its upper end face to its lower end face. The advantage of this design is that the tapered part has a certain amount of deformation, making it easier to lock and fix the load-bearing clamp body or the contact wire clamp body, and the locking and fixing effect is better;

[0041] (3) The die-forged integral ring obtained by the precision die-forging forming process is made of pure copper material, which has better toughness and vibration and friction resistance than silicon bronze stamping parts. It is not prone to brittle fracture during service, nor is it prone to elastic deformation and plastic deformation. It has a long effective service life, effectively ensures the connection stability between the contact ring and other components, and is very beneficial to improving the safe operation stability of the catenary.

[0042] (4) To improve the operating reliability and service life of the overall suspension wire, the suspension wire adopted in the present utility model is a composite fatigue-resistant suspension wire with a stainless steel wire in the central strand. The stainless steel wire is concentric and coaxial with the suspension wire. The composite fatigue-resistant suspension wire has better vibration and wear resistance compared with the copper-magnesium alloy as the suspension wire, is not prone to fatigue fracture, has a longer service life. The composite fatigue-resistant suspension wire with a stainless steel wire in the central strand has a breaking force and a number of repeated bending times at break far exceeding those of ordinary JTMH10 copper alloy stranded wires, which is very beneficial to improving the safe operation stability of the catenary;

[0043] (5) The conventional suspension loop is a silicon bronze stamping part, specifically made of CuNi2Si copper strip. The product after stamping and forming is a thin sheet with a curvature. When cracks are generated due to collision and wear, the cracks are extremely easy to spread axially in subsequent collisions and cause fracture; after the present utility model replaces it with forged T2 copper, the arc section of the obtained forged integral suspension loop is a solid body, and the T2 copper has a lower hardness. When it collides with the heart-shaped insert ring, it will only become thinner during wear and is not easy to generate cracks. In addition, the fit degree between the worn suspension loop and the heart-shaped insert ring is higher (changing from point contact to surface contact), which greatly slows down the subsequent wear progress and is very beneficial to improving the safe operation stability of the catenary;

[0044] (6) The traditional suspension wire adopts JTMH10 copper alloy stranded wire with a cross-sectional area of 10 mm 2 . The suspension wire adopted in the present utility model has a cross-sectional area not limited to 10 mm 2 , and can be 10 mm 2 to 14 mm 2 , which can solve the fracture problem caused by insufficient strength of the traditional suspension wire.
