Description

Technical Field

[0001] This utility model belongs to the field of tubular chain machine technology, and particularly relates to a chain structure for a wire rope tubular chain machine. Background Technology

[0002] In the field of chain structure for tubular chain conveyors, existing technologies mostly employ the method of crimping steel wire ropes with metal sleeves. However, this method has many drawbacks: First, the crimping process can damage the steel wire rope, severely affecting its service life; second, if there is a gap error when crimping the steel wire rope and the sleeve, the pitch of the assembled discs will be inaccurate, causing the equipment to malfunction, and the operation of cutting the sleeve off the steel wire rope is difficult, and the steel wire rope is more severely damaged after a second crimping; third, under strong pressure, the two ends of the sleeve are prone to developing uneven sharp corners, which, under long-term pressure from the discs, will damage the discs and cause them to be squeezed out of the sleeve, resulting in equipment downtime; fourth, the discs are designed with a symmetrical top and bottom, and when conveying granular materials, the discs tilt at bends, which will squeeze the granular materials and increase the breakage rate; fifth, the crimping of the sleeve must be completed on-site, and the replacement of parts requires specialized tools and personnel, making the replacement extremely difficult. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a steel wire rope tube chain machine chain structure, which has the advantages of protecting the steel wire rope without crimping, easy assembly and pitch adjustment, disc damage prevention, reduced particle breakage rate, and easy maintenance and replacement. It solves the problems of easy damage to the steel wire rope, difficult adjustment of disc pitch and easy damage by sharp corners, high particle breakage rate, and professional operation required for parts replacement in the prior art metal sleeve crimping structure. It can extend the service life of the steel wire rope and disc, improve the stability of equipment operation, and reduce the difficulty of assembly and maintenance.

[0004] This utility model is implemented as follows: a chain structure for a wire rope tube chain machine includes a fixing clamp, fastening screws, a disc body, and a joint disc fixing screw. The fixing clamp is a two-part fixing brake clamp with protrusions in its inner hole. The fixing clamp is fixed to the wire rope by two fastening screws. Tightening the joint disc fixing screws allows the disc body to wrap around the fixing clamp. Both ends of the fixing clamp are precision-machined flat surfaces. When both ends of the wire rope are pressed by the fixing clamps, the threaded connection between the joint disc fixing screws and the disc body causes the chain to form a ring.

[0005] This design eliminates the traditional metal sleeve crimping method, employing a two-part fixing clamp and screw / disc body connection structure. Firstly, it eliminates the need for crimping, avoiding damage to the wire rope and significantly extending its service life. Secondly, during assembly, the position of the fixing clamp on the wire rope can be flexibly adjusted, precisely controlling the disc pitch. If errors occur, disassembly and adjustment are easy without cutting off parts, reducing assembly difficulty and the risk of secondary damage to the wire rope, thus improving manufacturing and maintenance efficiency. Simultaneously, the precision-machined flat surfaces at both ends of the fixing clamp eliminate the squeezing damage to the disc caused by the sharp corners of the traditional clamping sleeve, reducing equipment downtime due to disc damage and ensuring equipment operational stability.

[0006] As a preferred embodiment of this invention, the protrusions in the inner hole of the fixing clamp are evenly distributed to increase the friction with the wire rope.

[0007] This design increases the contact friction between the fixing clamp and the wire rope by evenly distributed protrusions, making the fixing clamp more secure and reliable on the wire rope. Even when the tubular chain machine is subjected to large tension and friction during operation, it can effectively prevent the fixing clamp from sliding relative to the wire rope, thereby ensuring the stability of the disc position, ensuring accurate chain pitch, and maintaining normal operation of the equipment.

[0008] As a preferred embodiment of this utility model, the disk body has internal threads, the connector disk fixing screw has external threads, and the threaded connection between the connector disk fixing screw and the disk body is an anti-loosening threaded connection.

[0009] This feature effectively prevents the fixing screws of the connector disc from loosening due to vibration or other factors during equipment operation, ensuring the stability of the chain ring connection, avoiding chain disconnection and other malfunctions caused by loose connections, improving the overall reliability and service life of the chain, and reducing the frequency of equipment maintenance.

[0010] As a preferred embodiment of this invention, the disk body has an asymmetrical structure.

[0011] With this design, the asymmetrical disc body can reduce the squeezing effect of the disc tilting at bends on the granular material when conveying granular materials, thereby reducing the breakage rate of the granular material and improving the quality of material conveying; at the same time, the asymmetrical structure can also reduce the wear of the disc itself, extend the service life of the disc, and reduce the frequency of replacement of parts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: It uses a two-part fixing clamp and fastening screws to fix the wire rope, eliminating the need for crimping, thus avoiding damage to the wire rope due to crimping and effectively extending the service life of the wire rope.

[0013] During assembly, the disc pitch can be controlled by adjusting the position of the clamp on the wire rope. The operation is simple, and even if errors occur, it is easy to disassemble and adjust without cutting off parts, thus avoiding secondary damage to the wire rope, reducing assembly difficulty and improving production efficiency.

[0014] The fixed clamp has precision-machined flat surfaces at both ends, eliminating the sharp corners at both ends of the traditional pressure sleeve, avoiding squeezing and damaging the disc, reducing downtime due to disc damage, and ensuring the stability of equipment operation.

[0015] The asymmetrical disc design reduces the pressure on the granular material caused by the disc tilting at bends during conveying, thus lowering the breakage rate of the granular material and reducing disc wear, thereby protecting the disc's service life.

[0016] The chain uses a detachable connection method, so no special tools or personnel are needed to replace parts. Only the fastening screws and other parts need to be removed, which greatly reduces the difficulty of repairing and replacing the chain and improves the convenience of equipment maintenance.

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] refer to Figures 1 to 3As shown in the figure, the steel wire rope tube chain machine chain structure provided by this utility model includes a fixing clamp 1, a fastening screw 2, a disc body 3, and a joint disc fixing screw 4. The fixing clamp 1 is a two-half fixing brake clamp. The inner hole of the fixing clamp 1 is provided with protrusions. The fixing clamp 1 is fixed to the steel wire rope by two fastening screws 2. Tightening the joint disc fixing screw 4 can make the disc body 3 wrap around the fixing clamp 1. The two ends of the fixing clamp 1 are precision machined flat surfaces. When the two ends of the steel wire rope are respectively pressed by the fixing clamp 1, the joint disc fixing screw 4 and the disc body 3 are threadedly connected to form a ring of chain.

[0024] The above solution abandons the traditional metal sleeve crimping method and adopts a connection structure in which a two-part fixing clamp 1 is matched with screws and disc body 3. On the one hand, crimping is eliminated, avoiding damage to the wire rope caused by crimping and greatly extending the service life of the wire rope. On the other hand, the position of the fixing clamp 1 on the wire rope can be flexibly adjusted during assembly, and the disc pitch can be precisely controlled. If errors occur, disassembly and adjustment are easy without cutting off parts, reducing assembly difficulty and the risk of secondary damage to the wire rope, and improving manufacturing and maintenance efficiency. At the same time, the precision-machined flat surfaces at both ends of the fixing clamp 1 eliminate the squeezing damage to the disc caused by the sharp corners at both ends of the traditional pressing sleeve, reducing equipment downtime caused by disc damage and ensuring the stability of equipment operation.

[0025] Specifically, the protrusions in the inner hole of the fixing clamp 1 are evenly distributed to increase the friction with the wire rope.

[0026] By adopting the above scheme, the evenly distributed protrusions increase the contact friction between the fixing clamp 1 and the wire rope, making the fixing clamp 1 more firmly and reliably fixed on the wire rope. Even when the tubular chain machine is subjected to large tension and friction during operation, it can effectively prevent the fixing clamp 1 from sliding relative to the wire rope, thereby ensuring the stability of the disc position, ensuring the accuracy of the chain pitch, and maintaining the normal operation of the equipment.

[0027] Specifically, the disk body 3 has internal threads, the connector disk fixing screw 4 has external threads, and the threaded connection between the connector disk fixing screw 4 and the disk body 3 is an anti-loosening threaded connection.

[0028] By adopting the above solution, the anti-loosening threaded connection can effectively prevent the joint disc fixing screw 4 and the disc body 3 from loosening due to vibration and other factors during equipment operation, ensuring the stability of the chain ring connection, avoiding chain disengagement and other failures caused by loose connection, improving the overall reliability and service life of the chain, and reducing the frequency of equipment maintenance.

[0029] Specifically, the disk body 3 has an asymmetrical structure.

[0030] By adopting the above scheme, the asymmetrical disc body 3 can reduce the squeezing effect of the disc tilting at the bend on the granular material when conveying granular material, thereby reducing the breakage rate of the granular material and improving the material conveying quality; at the same time, the asymmetrical structure can also reduce the wear of the disc itself, extend the service life of the disc, and reduce the frequency of replacement of parts.

[0031] The working principle of this utility model is as follows: In use, two fixing clips 1 are fixed to the two ends of the wire rope, and then the disc body 3 is fastened together. The middle disc body 3 is fixedly connected to one of the fixing clips 1. The fixing clip 1 is tightened by tightening screws 2. The friction between the inner hole protrusion of the fixing clip 1 and the surface of the wire rope securely installs the fixing clip 1 on the wire rope, preventing the fixing clip 1 from shifting. Next, the disc body 3 with internal threads is placed over the fixing clip 1 and tightened with the joint disc fixing screw 4 with external threads, so that the disc body 3 wraps around the fixing clip 1, thereby firmly fixing the disc body 3 to the wire rope. The disc body 3 and the joint disc fixing screw 4 adopt an anti-loosening thread connection, which can effectively prevent the two from loosening due to vibration and other factors during equipment operation, ensuring... The disc body 3 is positioned stably, allowing the chain to connect end to end in a loop, which is suitable for the working requirements of the tubular chain machine. During the operation of the tubular chain machine, the asymmetrical disc structure moves with the loop of the chain, pushing the granules within the machine. This reduces the pressure on the granules at the bends of the disc body 3, minimizing granule breakage. At the same time, the precision-machined flat surfaces at both ends of the fixing clamp 1 prevent the sharp corners that would cause wear and damage to the disc body 3, as is the case with traditional pressure sleeves. This ensures stable operation of the disc body 3, extends its service life, and guarantees the continuous and stable operation of the tubular chain machine. If a problem with the disc pitch is found during operation, simply loosen the fastening screws 2 and the joint disc fixing screws 4, adjust the position of the fixing clamp 1 on the wire rope, and re-fix it. This reduces the difficulty of equipment maintenance.
