[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Reference Figures 1-3 , a large pressure bar connection system for a lime kiln, used for the connection between a large pressure bar 1 and a bell cap. Lifting lugs 11 are symmetrically arranged at the top of the large pressure bar 1. A connection unit is connected to the lifting lugs 11. The top of the connection unit is connected to the bell cap. The connection unit includes a steel wire rope 2. An anti-wear device 3 is arranged between the steel wire rope 2 and the large pressure bar 1, converting the flexible connection between the steel wire rope 2 and the large pressure bar 1 into a rigid connection between the large pressure bar 2 and the anti-wear device 3, reducing the friction force acting on the steel wire rope 2, enhancing the anti-wear performance between the steel wire rope 2 and the large pressure bar 1, and thus extending the service life of the steel wire rope 2.
[0021] The anti-wear device 3 includes an anti-wear ring 31. The anti-wear ring 31 can be heart-shaped. The lifting lug 11 can be connected to the anti-wear ring 31. The anti-wear ring 31 can be U-shaped. The outer ring wall of the anti-wear ring 31 is wound with the steel wire rope 2, which can increase the contact area between the anti-wear ring 31 and the steel wire rope 2, thereby enhancing the connection strength between the anti-wear ring 31 and the steel wire rope 2. The inner ring wall of the anti-wear ring 3 is connected to the large pressure bar 1 and can pass through the lifting lug 11 to realize the connection between the anti-wear ring 3 and the lifting lug 11. Through the anti-wear ring 31, the flexible connection between the steel wire rope 2 and the large pressure bar 1 can be converted into a rigid connection, and the acting area of the steel wire rope 2 can be increased, thereby reducing the friction force acting on the steel wire rope 2, enhancing the anti-wear performance between the steel wire rope 2 and the large pressure bar 1, and thus extending the service life of the steel wire rope 2.
[0022] In some embodiments, the anti-wear device 3 further includes a limit sleeve 32. The limit sleeve 32 covers the top of the outer ring wall of the anti-wear ring 31. A rope-passing hole is provided between the limit sleeve 32 and the anti-wear ring 31. The steel wire rope 2 can pass through the rope-passing hole and be wound around the anti-wear ring 31. The limit sleeve 32 can prevent the steel wire rope 2 from detaching from the anti-wear ring 31, enhancing the connection safety between the anti-wear device and the steel wire rope 2.
[0023] In some embodiments, the wire rope 2 may include an upper connection section 21 and a lower connection section 22. The bottom of the upper connection section 21 is connected to the anti-wear device 3. A detachable device 4 is provided between the top of the upper connection section 21 and the lower connection section 22. The detachable device 4 includes at least two connection buckles 41. Both the upper connection section 21 and the lower connection section 22 pass through the connection buckles 41. The detachable connection between the upper connection section 21 and the lower connection section 22 can be realized through the connection buckles 41, so as to facilitate the replacement of the lower connection section 22 after wear, facilitate later maintenance, reduce the loss of the wire rope 2, and save costs.
[0024] In some embodiments, at least one fastening buckle 5 is provided on the lower connection section 22. Both ends of the lower connection section 22 pass through the fastening buckle 5, which can enhance the tightness of the two ends of the lower connection section 22 joined together, thereby enhancing the connection strength of the wire rope 2 on the anti-wear device 3.
[0025] In some embodiments, the structure of the fastening buckle 5 may be the same as that of the connection buckle 41, including a base 51, both of which can be galvanized chucks. It may include a base 51. A clamping ring 52 is provided on the base 51. Clamping grooves 53 are symmetrically provided on both sides of the clamping ring 52. An inverted U-shaped ring 54 is provided on the base 51. Both ends of the lower connection section 22 are provided between the inverted U-shaped ring 54 and the clamping groove 53. Both ends of the inverted U-shaped ring 54 penetrate through the base 51 and are screwed with fastening nuts 55. By locking the position of the fastening nuts 55 on the inverted U-shaped ring 54, the gap between the inverted U-shaped ring 54 and the clamping groove 53 is adjusted, and then the locking and loosening of the lower connection section 22 are realized.
[0026] In some embodiments, a U-shaped shackle 6 is provided between the lifting lug 11 and the anti-wear ring 31. The U-shaped shackle 6 is a prior art and will not be elaborated here. Through the transfer of the U-shaped shackle 6, the disassembly and assembly between the lifting lug 11 and the anti-wear ring 31 are facilitated.
[0027] The specific working principle is as follows:
[0028] Pass the lower connection section 22 through the rope-passing hole, wind it around the anti-wear ring 31, and fix both ends of the lower connection section 22 through the fastening buckle 5. Use a plurality of connection buckles 41 to connect the upper connection section 21 and the lower connection section 22 to complete the connection between the wire rope 2 and the anti-wear device 3.
[0029] Use a U-shaped shackle 6 on the lifting lug 11 to connect the anti-wear device 3, thereby completing the assembly of the entire connection system.
[0030] When the stone-lifting vehicle hits the large pressure bar 1, the large pressure bar 1 is stressed, and the force is transmitted to the wire rope 2 through the U-shaped shackle 6 and the anti-wear device 3, avoiding direct contact between the lifting lug 11 and the wire rope 2, resulting in damage to the wire rope 2 at the connection, thereby extending the service life of the wire rope 2.
[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
