Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a forged spring seat for rail transit that can be assembled quickly. Background Technology

[0002] Rail transit refers to transportation vehicles or systems that require operating vehicles to run on specific tracks. It includes various types such as traditional railways and urban rail transit. It is characterized by large capacity, high speed, energy saving and environmental protection. Rail transit forgings are key components used in rail transit vehicles such as railways, subways and high-speed railways. They are made through forging processes and have the characteristics of high strength, wear resistance and reliability. Rail transit forgings are the core basic components that support the safe, reliable and efficient operation of the entire system. Their importance is reflected in many key dimensions and is directly related to train performance, passenger safety, operating costs and system life.

[0003] The existing technical solutions mentioned above have the following drawbacks: the spring seats used in existing rail transit lack a structure that is easy to install and use, making installation and subsequent use extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a forged spring seat for rail transit that can be assembled quickly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-assembly forged spring seat for rail transit includes a spring seat body, a mounting base fixedly connected to the outer side of the spring seat body, an external thread provided on the outer side of the mounting base, a connector mounted on the outer side of the mounting base, an internal thread provided on the inner side of the connector, a connecting post fixedly connected to the outer side of the connector, and a groove provided inside the spring seat body.

[0007] By adopting the above technical solution, two sets of mounting seats are added to the outside of the spring seat body to install the spring assembly. However, in order to ensure that the structural components can be replaced and maintained in the future, connecting parts are added. The connecting parts are installed and connected to the spring seat body to meet the usage requirements.

[0008] Furthermore, the interior of the spring seat body is provided with a positioning hole and a countersunk hole on the outer side of the groove. A positioning pin is inserted into the positioning hole, and a mounting bolt is inserted into the countersunk hole.

[0009] By adopting the above technical solution, adding positioning pins and mounting bolts, the mounting bolts can be used in conjunction with the supporting equipment later. The positioning pins can be positioned and installed before installation and locking, and then locked and fixed, thereby improving the accuracy of the installation structure.

[0010] Furthermore, the mounting base, external thread, connector, and internal thread are symmetrically arranged in twos about the vertical center line of the spring seat body. The external thread and internal thread are threadedly connected, and the connector adopts an inclined structure.

[0011] By adopting the above technical solution and adding two sets of symmetrical structures, the spring assembly can be installed from both sides, which facilitates operation.

[0012] Furthermore, two of each of the positioning holes, countersunk holes, positioning pins, and mounting bolts are provided. The positioning pins and positioning holes are engaged, and the mounting bolts extend through the countersunk holes to the outside of the spring seat body.

[0013] By adopting the above technical solution, installation and use are convenient.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] The system comprises a spring seat body, mounting base, connector, locating pin, and mounting bolts. A detachable structure is added to the outside of the spring seat body, allowing the spring assembly to be mounted on the connecting post on the outside of the connector. The outside of the connector can be disassembled and installed at any time. The addition of locating pins and mounting bolts allows the spring seat body to be positioned first and then locked in place, improving the accuracy of the installation and making it more convenient to use. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0017] Figure 2 This is a schematic diagram of the disassembled structure of this utility model.

[0018] In the diagram, 1 is the spring seat body; 2 is the mounting base; 3 is the external thread; 4 is the connector; 5 is the internal thread; 6 is the connecting post; 7 is the groove; 8 is the positioning hole; 9 is the countersunk hole; 10 is the positioning pin; and 11 is the mounting bolt. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1-2A quick-assembly forged spring seat for rail transit includes a spring seat body 1. A mounting base 2 is fixedly connected to the outer side of the spring seat body 1. The outer side of the mounting base 2 has an external thread 3. A connector 4 is mounted on the outer side of the mounting base 2. The inner side of the connector 4 has an internal thread 5. A connecting post 6 is fixedly connected to the outer side of the connector 4. A groove 7 is formed inside the spring seat body 1. A positioning hole 8 and a countersunk hole 9 are formed inside the spring seat body 1 outside the groove 7. A positioning pin 10 is inserted into the positioning hole 8, and a mounting bolt 11 is inserted into the countersunk hole 9. Two sets of mounting bases 2 are added to the outer side of the spring seat body 1 to install spring assemblies. However, to ensure that the structural components can be replaced and maintained later, a connector 4 is added. The connector 4 is installed and connected to the spring seat body 1 to meet the usage requirements. Positioning pins 10 and mounting bolts 11 are added. The mounting bolts 11 are later installed and used with matching equipment. Positioning pins 10 can be positioned and installed before locking, and then locked to improve the accuracy of the installation structure.

[0021] like Figure 1-2 As shown, mounting base 2, external thread 3, connector 4 and internal thread 5 are symmetrically arranged in twos about the vertical center line of spring seat body 1. External thread 3 and internal thread 5 are threaded together. Connector 4 adopts an inclined structure. Positioning hole 8, countersunk hole 9, positioning pin 10 and mounting bolt 11 are provided in twos. Positioning pin 10 and positioning hole 8 are engaged. Mounting bolt 11 extends through countersunk hole 9 to the outside of spring seat body 1.

[0022] The implementation principle of this embodiment is as follows: the connector 4 is installed on the mounting base 2 on the outside of the spring seat body 1. The two are connected by external thread 3 and internal thread 5, which makes disassembly convenient. At the same time, the spring assembly can be directly installed on the connecting column 6 for installation and use. When installing the spring seat body 1, the positioning pin 10 can be positioned and installed, and then locked and fixed by the mounting bolt 11 to improve the accuracy of the structure installation.
