Description

Technical Field

[0001] The utility model relates to the technical field of carrier sprockets, and more specifically, to a supporting carrier sprocket. Background Art

[0002] The carrier sprocket is an important component of the traveling parts of chain-driven machinery such as excavators. It is generally used to support the crawler chain to ensure the normal travel of chain-driven equipment such as excavators.

[0003] Among them, the patent with announcement number CN219192386U discloses a double-supported carrier sprocket, in which a reinforcement ring is fixedly installed in the middle of the sprocket body, and an inverted trapezoidal groove is opened on both sides of the reinforcement ring. A convex support splicing ring is clamped and connected in the inverted trapezoidal groove. A main connecting annular groove is opened on the outside of the inverted trapezoidal groove, and a main connecting seat is provided on the outside of the convex support splicing ring. The main connecting seat and the main connecting annular groove are matched in size. The utility model provides a double-supported carrier sprocket;

[0004] When this structure is in use, a trapezoidal support structure is formed by the inverted trapezoidal groove and the convex support splicing ring. At the same time, the inner support ring supports the trapezoidal support structure formed by the inverted trapezoidal groove and the convex support splicing ring. The outer support ring forms a support structure with the outer ring groove, and cooperates with the inner support ring to form a double support structure, which improves the stability and overall strength of the reinforcement ring. The trapezoidal support structure is formed by the main connecting seat in the main connecting annular groove. The support ring and the outer support ring, the convex support splicing ring, and the main connecting seat cooperate with each other to support the inside of the reinforcement ring. However, this structure is not easy to position the chain when in use, and the friction between the chain and the supporting wheel is small, which is prone to slipping. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a supporting sprocket, which aims to solve the problems raised in the above-mentioned background technology.

[0006] The utility model provides the following technical solutions: a support type sprocket, comprising a support seat, wherein a positioning support assembly is provided in the middle of the support seat;

[0007] The positioning support assembly includes two positioning trays arranged in the middle of the support base, and a plurality of reinforcing side baffles are distributed on the outside of each positioning tray;

[0008] A limit block is fixedly provided on one side of each of the plurality of reinforced side baffles, and a limit slot for limiting the chain is formed between each two adjacent limit blocks. The plurality of limit blocks are fixed on the positioning tray, and the limit blocks and the reinforced side baffles are arranged in a stepped shape.

[0009] It can be seen that in the above technical solution, when the device is lifting the chain, the chain is located between two adjacent limit blocks and the chain is positioned through the limit card slot, thereby increasing the friction between the chain and the device, and avoiding the chain slipping when it contacts the device when subjected to force, and the limit block and the reinforced side baffle are arranged in a stepped shape, so that when the chain is located in the limit card slot, the reinforced side baffle can limit the outer side of the chain, and the limit block can position the end of the chain, ensuring the stability of the device supporting the chain.

[0010] Optionally, in a possible embodiment, a center hole is provided through the middle of the positioning tray, an elongated groove is provided on one side of the inner wall of the center hole, a support shaft is provided in the middle of the center hole, a reinforced locking block is fixedly provided on the outer side of the support shaft, the reinforced locking block matches the elongated groove, the reinforced locking block is clamped with the elongated groove, both ends of the support shaft extend to the support seat and are rotatably connected to the support seat, a staggered opening is provided at the bottom of the inner wall of the limiting slot, the vertical cross-section of the staggered opening is arc-shaped, the vertical cross-section of the support seat is polygonal, and the positioning tray is rotatably connected to the support seat;

[0011] The technical effects and advantages of this utility model are:

[0012] By setting up the positioning support assembly, compared with the existing technology, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the positioning tray and the support shaft are rotatably connected to the support base, which is easy to install. The polygonal cross-sectional shape of the support base can be used to adapt to different installation surfaces during installation, thereby improving the convenience during construction.

[0013] When the device is lifting the chain, the chain is located between two adjacent limit blocks and the limit slots are used to position the chain, thereby increasing the friction between the chain and the device and preventing the chain from slipping when in contact with the device under force.

[0014] In addition, the limit block and the reinforced side baffle are arranged in a stepped shape, so that when the chain is located in the limit slot, the reinforced side baffle can limit the outer side of the chain, and the limit block can position the end of the chain to ensure the stability of the chain supported by the device.
