[0001] The utility model belongs to the technical field of switch rail joints, and more specifically, particularly relates to a switch rail joint. Background Art

[0002] Turnouts and their conversion equipment are important basic equipment of railways, which are closely related to the safety and efficiency of railway operation. At present, large-number turnouts of No. 18 and No. 42 are generally adopted in China's high-speed railways. Such turnouts are mostly laid at the connecting lines and the turnout points of two lines, and usually the switch machine is used to control the turnout conversion. Such turnouts generally have movable switch rails. Checking whether the switch rail of the turnout is in the specified position is an essential part of railway conversion equipment. It is usually checked by the indicating rod of the switch machine, and its main checking method is to require the checking block of the switch machine to align with the indicating notch.

In addition, the main indicating rod joint 32 is made of a material with high durability and corrosion resistance, capable of working stably for a long time under various environmental conditions. Its structural design is simple and compact, not occupying too much space, which is convenient for system integration and layout.

[0027] A main disc spring group 33 is arranged in the main indicating rod hole. The main disc spring group 33 is placed between the main indicating rod joint 32 and the main indicating rod adjusting sleeve 31. There is a direct contact between the main indicating rod joint 32 and the main disc spring group 33. Through this contact, the main indicating rod joint 32 plays a key role in compressing the main disc spring group 33 to a specified pressure. First of all, the existence of the main disc spring group 33 provides an elastic support and buffering mechanism. It can absorb and relieve the influence of external forces, ensuring the stability and reliability of the system. Secondly, by compressing the main disc spring group 33 to a specified pressure, mechanical control and adjustment can be achieved. This helps to ensure the normal operation and precise movement of the system. In addition, the main disc spring group 33 has appropriate elasticity and durability, and can maintain good performance during long-term use. Its material and manufacturing process are carefully selected to ensure high quality and reliability. The contact between the main indicating rod joint 32 and the main disc spring group 33 ensures uniform force transmission and effective compression, avoiding unnecessary stress concentration and deformation.

[0028] The secondary adjustment assembly includes a secondary indicating rod adjusting sleeve 41, which is clamped in the secondary indicating rod hole to form a tight and stable connection. Inside the secondary indicating rod hole, a detachable secondary indicating rod plug 42 is provided, and the secondary indicating rod plug 42 is located at one end of the secondary indicating rod adjusting sleeve 41. The clamping method of the secondary indicating rod adjusting sleeve 41 ensures that it can be stably fixed in the secondary indicating rod hole, avoiding loosening or displacement. This enables the entire assembly to maintain a stable position and function during use. A secondary disc spring group 43 is provided between the secondary indicating rod plug 42 and the secondary indicating rod adjusting sleeve 41. The secondary indicating rod plug 42 is in direct contact with the secondary disc spring group 43 and applies a force to compress the secondary disc spring group 43 to a specific specified pressure value. The presence of the secondary disc spring group 43 provides an additional elastic support and buffering mechanism. It can effectively absorb and relieve the influence of external forces, enhancing the stability and reliability of the entire system. By compressing the secondary disc spring group 43 to the specified pressure value, precise mechanical control and adjustment can also be achieved. This helps to ensure the normal operation and precise movement of the system.

[0029] The secondary adjustment assembly further includes a secondary indicating rod joint 44. One end of this secondary indicating rod joint 44 is provided with a threaded section. The threaded section is clamped inside the secondary indicating rod adjusting sleeve 41 and establishes a connection with the joint outer sleeve 21. The setting of the threaded section enables the secondary indicating rod joint 44 to be firmly connected to the secondary indicating rod adjusting sleeve 41. It provides a reliable fixing method, ensuring the stability of the assembly during use. The other end of the secondary indicating rod joint 44 is connected to the switch machine, forming a complete system. The connection with the switch machine provides crucial support for the normal operation of the system.

[0030] Pin holes are provided on the long indicating rod 11 of the switch rail and the corresponding switch rail bending plate 12.

This can not only reduce the friction and wear between components, extend the service life of the system, but also improve the operating efficiency and performance of the system.

[0031] Specific usage method and function of this embodiment:

[0032] Before using the switch rail joint, first ensure that one end of the long indicating rod 11 of the switch rail is firmly connected to the adjusting sleeve 31 of the main indicating rod, and at the same time, the adjusting sleeve 41 of the auxiliary indicating rod is also tightly connected to the auxiliary indicating rod joint 44. Then, align the pin holes on the long indicating rod 11 of the switch rail with the corresponding switch rail bending plate 12, and then fix and connect them through the bolt pin 13 to ensure the stability and reliability of the entire system. After the connection is completed, lubricating oil can be injected through the oil injection hole on the outer sleeve 21 of the joint to ensure the lubrication of key parts, reduce the friction and wear between components, and extend the service life of the system. This step is very important for the maintenance and upkeep of the system and can improve the operating efficiency and performance of the system. During actual use, the operator can adjust the main adjustment component and the auxiliary adjustment component as needed for flexible adjustment. The threaded end between the adjusting sleeve 31 of the main indicating rod and the main indicating rod joint 32 ensures a firm connection, enabling the main indicating rod joint 32 to be fixed in the main indicating rod hole and establishing a firm connection node with the switch machine. Such a design ensures the accuracy of signal transmission and action control and provides convenience for the maintenance and repair of the system. The threaded connection method between the adjusting sleeve 41 of the auxiliary indicating rod and the auxiliary indicating rod joint 44 in the auxiliary adjustment component also provides a firm connection, ensuring the stability of the auxiliary indicating rod joint 44 in the auxiliary indicating rod hole. The elastic support and buffering mechanism of the auxiliary disc spring group 43 can effectively absorb the influence of external forces and enhance the stability and reliability of the entire system.
