Figs. 1-3 As shown, it includes: a first belt joint 1, a second belt joint 2, a first steel wire rope 3, a second steel wire rope 4, a third steel wire rope 5, a fourth steel wire rope 6, and a rubber filler layer. An overlap space is formed between the second belt joint 2 and the first belt joint. The first steel wire rope 3 is fixedly connected to the first belt joint 1 and extends beyond it, with a first gap between the first steel wire rope 3 and the second belt joint 2. The second steel wire rope 4 is fixedly connected to the first belt joint 1 and extends beyond it, with the first steel wire rope 3 and the second steel wire rope 4 alternating. The third steel wire rope 5 is fixedly connected to the second belt joint 2 and extends beyond it, with a gap between the third steel wire rope 5 and the second belt joint 2. A second gap is provided; the fourth steel wire rope 6 is fixedly connected to the second belt joint 2 and extends out of the second belt joint 2. The fourth steel wire rope 6, the first steel wire rope 3, and the third steel wire rope 5 are arranged alternately in sequence. The fourth steel wire rope 6 is arranged correspondingly to the second steel wire rope 4, and a third gap is provided between the fourth steel wire rope 6 and the second steel wire rope 4. The rubber filling layer is laid between the first belt joint 1 and the second belt joint 2 and can wrap the parts of the first steel wire rope 3, the second steel wire rope 4, the third steel wire rope 5, and the fourth steel wire rope 6 located in the overlapping space. Through the specific steel wire rope arrangement, the belt is subjected to more uniform force in all directions, which improves the tensile strength and load-bearing capacity of the belt joint. The rubber filling layer can enhance the connection strength between the steel wire rope and the belt joint and ensure the overall stability of the belt.

[0025] In a preferred embodiment, the rubber filler layer includes an upper rubber layer 7, a core rubber layer 8, and a lower rubber layer 9. The lower rubber layer 9 is laid in the overlap space and located below the first steel wire rope 3, the second steel wire rope 4, the third steel wire rope 5, and the fourth steel wire rope 6. The core rubber layer 8 is laid between the first steel wire rope 3, the second steel wire rope 4, the third steel wire rope 5, and the fourth steel wire rope 6. The upper rubber layer 7 is laid above the first steel wire rope 3, the second steel wire rope 4, the third steel wire rope 5, and the fourth steel wire rope 6.

[0026] In a preferred embodiment, the end of the first belt joint 1 is arranged in parallel with the second belt joint 2, and the end angle between the end edge of the first belt joint 1 and the side edge of the first belt joint 1 is 45°-60°. Such an angle design can ensure the connection strength and stability of the belt joint, facilitate construction operation, and reduce stress concentration.

[0027] In a preferred embodiment, the steel cord core conveying belt vulcanization lap joint structure further comprises a first transition structure 10 arranged at the end of the first belt joint 1. The first transition structure 10 comprises a first transition slope 11 and a second transition slope 12. The first transition slope 11 is inclined from the top surface of the first belt joint 1 to the middle part of the first belt joint 1, and is used for bonding and fixing with the upper rubber layer 7. The second transition slope 12 is inclined from the bottom surface of the first belt joint 1 to the middle part of the first belt joint 1, and is used for bonding and fixing with the lower rubber layer 9. The arrangement of the first transition structure 10 can make the stress gradually transition from the main stress area of the first belt joint 1 to other parts during the operation of the belt, thereby avoiding damage to the belt caused by sudden stress changes. At the same time, the bonding and fixing of the transition slope with the upper rubber layer 7 and the lower rubber layer 9 enhances the stability of the connection.

[0028] In a preferred embodiment, the angle of the first transition slope 11 is 20°-30°, and the angle of the second transition slope 12 is 20°-30°. The first transition slope 11 and the second transition slope 12 with specific angle ranges can further optimize the stress transition effect and improve the reliability of the belt joint.

[0029] In a preferred embodiment, the steel cord core conveying belt vulcanization lap joint structure further comprises a second transition structure 13 arranged at the end of the second belt joint 2. The second transition structure 13 comprises a third transition slope and a fourth transition slope. The third transition slope is inclined from the top surface of the second belt joint 2 to the middle part of the second belt joint 2, and is used for bonding and fixing with the upper rubber layer 7. The fourth transition slope is inclined from the bottom surface of the second belt joint 2 to the middle part of the second belt joint 2, and is used for bonding and fixing with the lower rubber layer 9. The second transition structure 13 plays a similar role to the first transition structure 10 at the second belt joint 2, thereby ensuring the uniform distribution of stress and the connection stability of the entire belt vulcanization lap joint structure.

[0030] In a preferred embodiment, the angle of the third transition slope is 20°-30°, and the angle of the fourth transition slope is 20°-30°, which is consistent with the angle of the first transition structure 10, thereby ensuring the consistency and coordination of the entire belt joint and further improving the reliability of the belt.

[0031] In a preferred embodiment, the length of the first steel wire rope 3 is twice the length of the second steel wire rope 4, the length of the third steel wire rope 5 is the same as that of the first steel wire rope 3, and the length of the fourth steel wire rope 6 is the same as that of the second steel wire rope 4, which can better adapt to the stress requirement of the belt and improve the tensile strength and carrying capacity of the belt.

[0032] In a preferred embodiment, the length of the first interval is 40mm-60mm, and the reasonable length of the first interval provides appropriate space for the filling and curing of the rubber, avoids excessive extrusion or mutual interference of the steel wire ropes during the vulcanization process, and ensures the quality of the vulcanization joint.

[0033] The principle and implementation mode of the specific examples are described in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model.
