Description

Technical Field

[0001] This utility model relates to the field of chains, and in particular to a lightweight logistics conveyor chain with guide wheels. Background Technology

[0002] Currently, lightweight steel conveyor chains are typically used in conjunction with straight or simple curved rail structures to achieve material transport.

[0003] Existing steel lightweight logistics conveyor chains generally suffer from the following problems: 1. The chain is prone to deviation and jamming at straight or curved sections, resulting in poor conveying stability; 2. Direct friction between the chain and the guide rail leads to severe wear after prolonged operation, shortening its service life; 3. The chain is difficult to replace, requiring replacement of the entire chain, resulting in high maintenance costs. Therefore, steel lightweight logistics conveyor chains on the market need further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight logistics conveyor chain with guide wheels, which features lightweight design, high guiding accuracy, and low maintenance costs.

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

[0006] A lightweight logistics conveyor chain with guide wheels includes alternating outer links and inner links, characterized in that: the outer link includes a U-shaped outer plate and two pins disposed on the outer plate, with a roller connected to one end of each pin;

[0007] The inner link includes a U-shaped inner plate, two sleeves disposed on the inner plate, a connecting plate connected to the sleeves and located on both sides of the inner plate, and an inner link plate. The sleeves in the inner link are fitted onto the pins of the adjacent outer links. The connecting plate has an outwardly bent connecting portion, and a horizontal guide roller is connected to the connecting portion.

[0008] Preferably, both the outer and inner plates include a top plate and side plates formed by bending the top plate from both sides. A pin is circumferentially connected to the two side plates of the outer plate, and a sleeve is connected to the two side plates of the inner plate.

[0009] Preferably, the top plate has a hollowed-out waist-shaped hole structure.

[0010] Preferably, the pin and the outer plate are clearance fit, and a retaining ring is provided on the pin to restrict the movement of the pin relative to the outer plate.

[0011] Preferably, the pin is a hollow structure.

[0012] The advantages of this utility model are:

[0013] 1. The hollow waist-shaped holes and hollow pins on the inner and outer plates can significantly reduce the weight of this chain;

[0014] 2. The pin shaft and the side plate of the outer auxiliary plate are clearance fit, so after the retaining ring is removed, the pin shaft can be easily pulled out, which facilitates the disassembly and replacement of individual chain links, thus eliminating the need to replace the entire chain and reducing the cost of use and maintenance.

[0015] 3. The rollers and horizontal guide rollers can work together in the guide rail to avoid contact between the chain and the guide rail, thus avoiding chain wear and significantly extending service life. At the same time, it can also improve the stability of chain transmission. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the lightweight logistics conveyor chain with guide wheels provided in this embodiment. Detailed Implementation

[0017] Combination Figure 1 The present invention provides a further description of the lightweight logistics conveyor chain with guide wheels.

[0018] A lightweight logistics conveyor chain with guide wheels includes alternating outer chain links 1 and inner chain links 2. The outer chain link 1 comprises a U-shaped outer plate 11 and two pins 12 disposed on the outer plate 11, with a roller 13 connected to one end of each pin 12. In use, two chains need to be used side-by-side; therefore, only one roller 13 needs to be provided on one side of each chain.

[0019] The inner link 2 includes a U-shaped inner plate 21, two sleeves 26 disposed on the inner plate 21, a connecting plate 22 connected to the sleeves 26 and located on both sides of the inner plate 21, and an inner link plate 25. Both the connecting plate 22 and the inner link plate 25 have through holes, and are installed to the end positions of the sleeves 26 through these through holes. The sleeves 26 in the inner link 2 are fitted onto the pins 12 of adjacent outer links 1, achieving alternating connection between outer links 1 and inner links 2. The connecting plate 22 has an outwardly bent connecting portion 23, on which a horizontal guide roller 24 is connected. The horizontal guide roller 24 and the roller 13 are located on the same side of the chain.

[0020] Both the outer plate 11 and the inner plate 21 include a top plate 111 and side plates 112 formed by bending the top plate 111 from both sides. The width of the top plate 111 in the outer plate 11 is greater than the width of the top plate 111 in the inner plate 21, allowing the two side plates 112 in the inner link to be distributed internally and externally with the two side plates 112 in the outer link 1. The top plate 111 and the side plates 112 are an integral structure, featuring simple structure and high strength. Two pins 12 are circumferentially limited and connected to the two side plates 112 of the outer plate 11, and are distributed one in front of the other. Two sleeves 26 are connected to the two side plates 112 of the inner plate 21, also distributed one in front of the other. Specifically, the length of the side plate 112 is greater than the length of the top plate 111, so the two ends of the side plate 112 are located outside the two ends of the top plate 111, and connection holes for mounting the pins 12 or sleeves 26 are provided at this location.

[0021] The pin 12 and the connecting hole on the side plate 112 of the outer auxiliary plate 11 are clearance fits to facilitate disassembly and assembly. To prevent the pin 12 from moving arbitrarily relative to the outer auxiliary plate 11, a groove is provided on the outer side wall of the pin 12, and a retaining ring is provided in the groove to restrict the movement of the pin 12 relative to the outer auxiliary plate 11. That is, the retaining ring abuts against the side wall of the side plate 112, thus playing a limiting role. The roller 13 is also limited by a retaining ring when mounted on the pin 12.

[0022] The sleeve 26 has a clearance fit with the connecting hole on the side plate 112 of the inner auxiliary plate 21, and an interference fit with the through holes on the connecting plate 22 and the inner chain plate 25, thereby achieving positioning between the sleeve 26, the inner auxiliary plate 21, the connecting plate 22 and the inner chain plate 25.

[0023] The circumferential limiting structure between the pin 12 and the connecting hole of the side plate 112 consists of a planar structure on the inner wall of the connecting hole of the outer plate 11 and a planar structure on the part of the pin 12 that corresponds to its fit in the connecting hole. These two planar structures restrict the rotation of the pin 12 within the connecting hole. Similarly, the sleeve 26 is circumferentially limited in its fit with the through holes on the connecting plate 22 and the inner chain plate 25. This means that the inner wall of the through hole has a planar structure, and the outer wall of the sleeve 26 corresponding to its fit in the through hole also has a planar structure. These two planar structures, when joined together, restrict the rotation of the sleeve 26 relative to the connecting plate 22 and the inner plate 21. Restricting the rotation of the pin 12 and the sleeve 26 within the connecting hole and through hole improves the stability of the entire chain.

[0024] Grease is applied between the pin 12 and the sleeve 26 to facilitate relative rotation between them.

[0025] The top plate 111 has a hollow waist-shaped hole structure 1111, and the pin 12 is a hollow structure. This structure can reduce the overall weight of the chain. In this embodiment, the weight can be reduced by 20%, achieving a lightweight design and saving materials.
