Description

Technical Field

[0001] This application relates to the technical field of chains, and in particular to an engineering conveyor chain with a rivetless connection. Background Technology

[0002] In modern industrial production, conveyor chains, as key equipment for material handling, are widely used in various industrial sectors such as mines, coal mines, and cement plants. With the advancement of technology and the development of industrial automation, the performance requirements for conveyor chains are becoming increasingly stringent, especially in terms of connection strength, durability, and production efficiency.

[0003] Traditional conveyor chains are mostly assembled using welding. However, these connection methods all have certain limitations. Although welded connections offer high strength, they also result in a large heat-affected zone, which can easily lead to a decline in material properties. Furthermore, defects such as cracks and porosity can occur during the welding process, affecting the chain's service life. In addition, welded chains are difficult to disassemble and reassemble from adjacent links, resulting in poor adaptability. Utility Model Content

[0004] To facilitate the connection of chain links, this application provides an engineering conveyor chain with a rivetless connection.

[0005] This application provides a riveted-free engineering conveyor chain, employing the following technical solution:

[0006] A riveted-free engineering conveyor chain includes several adjacent links. Each link includes a connecting portion, a middle portion, and two connecting plates. The connecting portion is installed on one side of the middle portion, and the two connecting plates are fixedly installed on the middle portion away from the connecting portion. The two connecting plates are parallel to each other, and the width of the two connecting plates is greater than the width of the connecting portion. A connecting hole is provided on the side wall of the connecting portion away from the middle portion, and corresponding assembly holes are provided on the two connecting plates. A pivot pin is provided between the two connecting plates, and assembly rods located at the assembly holes are provided at both ends of the pivot pin. The assembly rods are rotatably connected to the connecting plates.

[0007] By adopting the above technical solution, the connecting part of one link is moved to the middle of the two connecting plates of another link, and the axle pin is inserted into the connecting hole through the assembly hole, so that the axle pin is connected to the connecting part. The assembly rod is located in the assembly hole, so that when the connecting part rotates, it drives the axle pin to rotate, thereby connecting the adjacent links.

[0008] Optionally, the cross-section of the pin is elliptical, and the size of the connecting hole matches the size of the pin's cross-section.

[0009] By adopting the above technical solution, the elliptical cross-section of the shaft pin is matched with the connecting hole of the connecting part, so that the connecting part drives the shaft pin to rotate when it rotates, thereby improving the stability of the connection between adjacent chain links.

[0010] Optionally, the cross-section of the assembly rod is circular, and the diameter of the cross-section of the assembly rod is smaller than the minor axis length of the cross-section of the connecting shaft.

[0011] By adopting the above technical solution, the assembly rod with a circular cross-section can easily rotate within the assembly hole.

[0012] Optionally, the size of the mounting hole matches the cross-sectional size of the shaft pin.

[0013] By adopting the above technical solution, the size of the assembly hole matches the size of the cross-section of the pin. When the pin rotates, the pin is prevented from disengaging from the assembly hole because both the assembly hole and the cross-section of the pin are elliptical.

[0014] Optionally, the outer wall of the connection position between the connecting plate and the middle part is set as an inclined surface, and the inclined surface and the connection position between the connecting plate and the middle part are both chamfered.

[0015] By adopting the above technical solution, the beveled surface and chamfer make it easier for users to pick up the chain links for assembly.

[0016] Optionally, the connecting part, the middle part and the two connecting plates are integrally formed.

[0017] By adopting the above technical solution, the integrally molded connecting part, middle part and connecting plate improve the overall strength of the chain link.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] Move the connecting part of one link to the middle of the two connecting plates of another link, insert the pin through the assembly hole into the connecting hole, so that the pin is connected to the connecting part. The assembly rod is located in the assembly hole, so that when the connecting part rotates, it drives the pin to rotate, thus connecting the adjacent links. Attached Figure Description

[0023] The present application will be further described in detail below with reference to all the accompanying drawings.

[0024] This application discloses an engineering conveyor chain with a rivetless connection.

[0025] Reference Figure 1 and Figure 2 A riveted-free engineering conveyor chain includes several adjacent chain links 1. Each chain link 1 includes a connecting part 2, a middle part 3, and two connecting plates 4. The connecting part 2 is installed on one side of the middle part 3, and the two connecting plates 4 are fixedly installed on the side of the middle part 3 away from the connecting part 2. The two connecting plates 4 are parallel to each other, and their width is greater than that of the connecting part 2. A connecting hole 21 is provided on the side wall of the connecting part 2 away from the middle part 3. The two connecting plates 4 have corresponding assembly holes 41. A pin 5 is provided between the two connecting plates 4. Assembly rods 51 located at both ends of the pin 5 and located in the assembly holes 41 are provided. The assembly rods 51 are rotatably connected to the connecting plates 4. When the connecting part 2 of one chain link 1 is moved to the middle of the two connecting plates 4 of another chain link 1, the pin 5 is inserted into the connecting hole 21 through the assembly hole 41, so that the pin 5 is connected to the connecting part 2. The assembly rods 51 are located in the assembly hole 41. When the connecting part 2 rotates, it drives the pin 5 to rotate, thus connecting the adjacent chain links 1.

[0026] The connecting part 2, the middle part 3, and the two connecting plates 4 are integrally formed. The integrally formed connecting part 2, the middle part 3, and the connecting plates 4 improve the overall strength of the chain link 1.

[0027] Reference Figure 2 The cross-section of the pin 5 is elliptical, and the size of the connecting hole 21 matches the size of the cross-section of the pin 5. The elliptical cross-section of the pin 5, when matched with the connecting hole 21 of the connecting part 2, allows the connecting part 2 to rotate, driving the pin 5 to rotate and improving the stability of the connection between adjacent links 1. The cross-section of the mounting rod 51 is circular, and the diameter of the mounting rod 51's cross-section is smaller than the minor axis length of the connecting shaft's cross-section. The circular cross-section of the mounting rod 51 facilitates rotation within the mounting hole 41. The size of the mounting hole 41 matches the size of the cross-section of the pin 5. When the pin 5 rotates, the elliptical cross-sections of both the mounting hole 41 and the pin 5 prevent the pin 5 from disengaging from the mounting hole 41.

[0028] Reference Figure 2 During the connection process, the connecting part 2 of the chain link 1 will drive the pin 5 connected to the connecting part 2 to rotate, so that the pin 5 is misaligned with the adjacent mounting hole 41. The pin 5 is located in the connecting hole 21 and there is friction between it and the connecting part 2, so the pin 5 will not come off the connecting hole 21, thus improving the stability of the connection between adjacent chain links 1.

[0029] In this configuration, with the two links 1 perpendicular to each other and the connecting hole 21 of the two links 1 coinciding with the mounting hole 41, the axle pin 5 is inserted into the connecting hole 21 of the other link 1 through the connecting mounting hole 41. The mounting rod 51 is located in the mounting hole 41 of the adjacent link 1. Then, the two links 1 are rotated 90 degrees relative to each other, thereby connecting the two links 1 together through the axle pin 5. Unless the two links 1 are perpendicular to each other again and the connecting hole 21 of the two links 1 coincides with the mounting hole 41, the axle pin 5 will connect the two links 1 and will not fall off between the two links 1.

[0030] Reference Figure 2 The outer wall of the connection position between the connecting plate 4 and the middle part 3 is set as a bevel 6, and the bevel 6 has chamfers at the connection positions between the connecting plate 4 and the middle part 3. The bevel 6 and the chamfers make it easier for the user to pick up the chain link 1 for assembly.

[0031] The implementation principle of a riveted connection engineering conveyor chain according to an embodiment of this application is as follows: the connecting part 2 of one link 1 is moved to the middle of the two connecting plates 4 of another link 1, and the axle pin 5 is inserted into the connecting hole 21 through the assembly hole 41 so that the axle pin 5 is connected to the connecting part 2. The assembly rod 51 is located in the assembly hole 41, so that when the connecting part 2 rotates, it drives the axle pin 5 to rotate, thereby connecting the adjacent link 1.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
