Description

Technical Field

[0001] The utility model relates to the technical field of conical springs for buffers, in particular to a conical spring structure for urban rail buffers. Background Art

[0002] The buffer is an important part of the urban rail structure. The conical spring used in the buffer is an important buffer structure. The conical spring structure uses the friction between the two sliding inclined planes of the conical spring to absorb energy. When the buffer is compressed by force, the rings are mutually extruded. At this time, most of the impact energy is stored in the outer conical spring. At the same time, part of the impact energy is converted into heat energy due to the mutual friction between the inclined planes of the inner and outer conical springs, so as to achieve the buffer effect.

[0003] Most of the existing conical spring structures for urban rail buffers are assembled by multiple inner and outer rings. When the multiple inner and outer rings rub against each other, the friction force will increase, which easily causes damage to the inner and outer rings. And rust will occur due to the friction between the inner and outer rings. Therefore, the anti-wear performance and rust-proof performance of the conical spring structure are poor, which in turn affects the service life of the conical spring structure. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the poor anti-wear performance and rust-proof performance of the conical spring structure in the prior art, one of the purposes of the present utility model is to provide a conical spring structure for urban rail buffers.

[0005] One of the purposes of the present utility model is achieved by adopting the following technical solution: A conical spring structure for urban rail buffers, including a conical spring mechanism: The conical spring mechanism includes a first outer ring, the inner wall of the first outer ring is inserted with a first inner ring, the outer surface of one side of the first inner ring is sleeved with a second outer ring, the inner wall of one side of the second outer ring is inserted with a second inner ring, the outer surface of one side of the second inner ring is sleeved with a third outer ring, the inner wall of one side of the first outer ring is inserted with a first half ring, and the inner wall of one side of the third outer ring is inserted with a second half ring; The surfaces of the first outer ring, the first inner ring, the second outer ring, the second inner ring, the third outer ring, the first half ring and the second half ring are all coated with Castrol paint. By coating with Castrol paint, it is convenient to enhance the overall anti-wear performance and rust protection of the conical spring mechanism, thereby enhancing the overall buffer effect of the conical spring mechanism and effectively extending the service life of the conical spring mechanism.

[0006] According to the described conical spring structure for urban rail buffers, the conical spring mechanism is an assembled structure. It is convenient to disassemble and replace a certain ring body in the conical spring mechanism, thereby reducing the replacement cost.

[0007] According to the described conical spring structure for urban rail buffers, the inner wall of the first outer ring is symmetrically provided with first conical surfaces, the outer surface of the first inner ring is symmetrically provided with second conical surfaces, and the first half-ring is provided with third conical surfaces on the side close to the first conical surfaces. This facilitates the mutual friction and installation between the ring bodies and is convenient to use.

[0008] According to the described conical spring structure for urban rail buffers, the taper of the first conical surfaces and the second conical surfaces is adapted, the taper of the third conical surfaces and the first conical surfaces is adapted, and Castrol coating is applied on the first conical surfaces, the second conical surfaces and the third conical surfaces. This facilitates the mutual installation between the ring bodies and enhances the anti-wear performance between the ring bodies.

[0009] According to the described conical spring structure for urban rail buffers, the sizes and structures of the second outer ring and the third outer ring are the same as those of the first outer ring. This facilitates cost savings.

[0010] According to the described conical spring structure for urban rail buffers, the sizes and structures of the second inner ring and the first inner ring are the same. This facilitates the adaptation of the sizes of the respective ring bodies.

[0011] According to the described conical spring structure for urban rail buffers, the sizes and structures of the second half-ring and the first half-ring are the same. This facilitates the connection between the first outer ring and the third outer ring.

[0012] According to the described conical spring structure for urban rail buffers, the axis lines of the first outer ring, the first inner ring, the second outer ring, the second inner ring, the third outer ring, the first half-ring and the second half-ring coincide. This improves the installation accuracy and precision of the conical spring mechanism.

[0013] The beneficial effects of the above solutions are:

[0014] 1. Through the setting of the conical spring mechanism and Castrol coating, the number of the conical spring mechanism can be assembled by multiple ring bodies, thereby enhancing the overall buffering effect of the conical spring mechanism. And the assembly method can facilitate the replacement of a certain ring body, thus saving the replacement cost. At the same time, the application of Castrol coating enhances the anti-wear performance and rust prevention ability between the ring bodies, and thus extends the service life of the conical spring mechanism.

[0015] 2. Through the setting of the conical spring mechanism, the sizes of multiple outer rings in the conical spring mechanism are the same, and multiple inner rings and outer rings are adapted to the sizes of multiple outer rings, thus facilitating assembly. And the assembly design is on the same axis line, thus improving the installation accuracy of the conical spring mechanism and the overall aesthetics of the conical spring mechanism.

The conical spring mechanism 1 is an assembled structure. The inner wall of the first outer ring 101 is symmetrically provided with a first tapered surface 3. The outer surface of the first inner ring 102 is symmetrically provided with a second tapered surface 4. The side of the first half ring 106 close to the first tapered surface 3 is provided with a third tapered surface 5. The taper of the first tapered surface 3 and the second tapered surface 4 is adapted. The taper of the third tapered surface 5 and the first tapered surface 3 is adapted. The Castrol coating 2 is coated on the first tapered surface 3, the second tapered surface 4 and the third tapered surface 5. It should be noted that: The conical spring mechanism 1 is of model 21500 and is assembled, and is used for the materials of the urban rail buffer. The hardness of the conical spring mechanism 1 after heat treatment is HRC44 - 48, and the shot peening intensity is 0.4A. When the first inner ring 102, the second inner ring 104, the first outer ring 101, the second outer ring 103, and the third outer ring 105 are compressed to the limit working height of 213mm ± 1mm, no permanent deformation should occur. When assembling the conical spring mechanism 1, first evenly apply the Castrol coating 2 on the first tapered surface 3, the second tapered surface 4 and the third tapered surface 5 of the first outer ring 101, the first inner ring 102, the second outer ring 103, the second inner ring 104, the third outer ring 105, the first half ring 106 and the second half ring 107, then insert the first inner ring 102 and the second inner ring 104 between the first outer ring 101, the second outer ring 103 and the third outer ring 105, and finally insert the first half ring 106 and the second half ring 107 into the inner walls of the first outer ring 101 and the third outer ring 105 close to the first inner ring 102 and the second inner ring 104 respectively, so as to complete the assembly of the conical spring mechanism 1.

Then insert the first inner ring 102 and the second inner ring 104 between the first outer ring 101, the second outer ring 103, and the third outer ring 105. Finally, insert the first half-ring 106 and the second half-ring 107 into the inner walls of the first outer ring 101 and the third outer ring 105 on the side close to the first inner ring 102 and the second inner ring 104 respectively, thus completing the assembly of the ring spring mechanism 1. The number of the ring spring mechanisms 1 can be composed of multiple ring bodies, thereby enhancing the buffering effect. And the assembly method can facilitate the replacement of a certain ring body, thus saving the replacement cost.
