Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt repair technology, and in particular relates to a steel wire rope core conveyor belt repair joint. Background Technology

[0002] Steel cord conveyor belts are a type of conveyor belt. They are mainly composed of multiple parallel steel cords, with molten rubber poured onto the steel cords to form the conveyor belt. However, in actual use, we have found that it is not easy to align and repair broken steel cords. In other words, repairing such conveyor belts is very troublesome. Welding is not an option because the broken steel cord is not long enough for a second splice. Replacing the steel cord core requires cutting off most of the rubber, which slightly affects the performance of the conveyor belt. Replacing the entire conveyor belt increases the cost. Utility Model Content

[0003] The purpose of this utility model is to provide a repair joint for steel wire rope core conveyor belts. By adopting a structural design with an added external joint, the two broken steel wire ropes can be reconnected to form a complete steel wire rope. The use of threaded locking also ensures the strength of the steel wire rope, thereby improving the strength of the repaired conveyor belt. The repair work is convenient, quick, low-cost, and fast, thus solving the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steel wire rope core conveyor belt repair joint includes two sleeves: three steel wire rope clamping grooves are opened on the inner side of the sleeve, a through hole is opened on one side of the inner cavity of the steel wire rope clamping groove, and a steel wire rope clamping groove communicating with the through hole is opened on the outer side of the sleeve. Both sides of the sleeve are integrally formed with a conversion end, and three openings are opened on one side of the conversion end. Locking rings are threaded on the surface of the conversion end on the two sleeves on the same side, and the inner side of the locking ring is provided with an internal thread that matches the external thread.

[0005] Preferably, one end of one side of the clamp is provided with multiple positioning holes, and one end of one side of the clamp is fixedly connected with multiple positioning blocks, and the positioning holes and positioning blocks on the two clamps are mutually compatible.

[0006] Preferably, one side of the clamp is provided with multiple wire rope cores, one of which is engaged within two clamps.

[0007] Preferably, the surfaces of multiple wire rope cores are coated with rubber strips.

[0008] Preferably, the surface of the adapter end is provided with an external thread, and the inner side of the locking ring is provided with an internal thread that matches the external thread.

[0009] Preferably, the inner side of the rubber belt forms a wire rope hole based on the wire rope core.

[0010] The beneficial effects of this utility model are: by adopting a structural design that adds an external joint, this utility model can reconnect the two broken wire ropes together to form a complete wire rope. The use of threaded locking also ensures the strength of the wire rope, thereby improving the strength of the conveyor belt after repair. The repair work is convenient, quick, low-cost, and fast.

[0011] This invention, through the setting of positioning holes and positioning blocks, allows the positioning blocks to be inserted into the corresponding positioning holes when the two sleeves are mated and engaged, thereby playing a positioning role in the engagement and assembly of the two sleeves and providing convenience for the user's repair work.

[0012] This invention utilizes the mutual compatibility of external and internal threads. When installing the locking ring, the external and internal threads will mesh together, thereby fixing the locking ring to the adapter end and the sleeve, thus enabling the broken wire rope to be firmly connected together.

[0013] This invention features a wire rope hole, which is formed by casting a rubber strip onto the wire rope core. This makes it easier and more convenient to peel off the rubber strip, thus providing convenience for users' repair work. Attached Figure Description

[0024] Example 1:

[0025] A repair joint for a steel wire rope conveyor belt includes two sleeves 1: three steel wire rope clamping grooves 2 are provided on the inner side of the sleeve 1, a through hole 3 is provided on one side of the inner cavity of the steel wire rope clamping groove 2, and a steel wire rope clamping groove 4 communicating with the through hole 3 is provided on the outer side of the sleeve 1. Both sides of the sleeve 1 are integrally formed with a conversion end 5, and three openings 7 are provided on one side of the conversion end 5. Locking rings 8 are threaded on the surface of the conversion end 5 on the two sleeves 1 on the same side, and the inner side of the locking ring 8 is provided with an internal thread 13 that matches the external thread 6.

[0026] The specific usage process is as follows: First, determine the breakage location of the steel wire rope on the conveyor belt. Then, cut off the rubber at that location to expose the broken steel wire rope. Next, join the two broken rope ends together and place them into one of the clamps 1. The scattered rope cores should be placed sequentially into the corresponding steel wire rope clamping groove 2, and the scattered rope ends should be passed sequentially through the corresponding through holes 3 and pulled out to the outside of the clamp 1. Then, bend the rope ends and gather them into the corresponding steel wire rope clamping groove 4. Next, merge the other clamp 1 onto the first clamp 1. During this process, the scattered rope ends should also be pulled out to the outside of the clamp 1 and finally gathered into the corresponding steel wire rope clamping groove 4. Finally, tighten the locking ring 8 onto the two clamps 1, thereby securing the two clamps... 1. When locking and assembling, it should be noted that the two locking rings 8 should be sequentially screwed onto the two clamps 1. The order can be determined by the user. The locking rings 8 pass from the outside of the wire rope clamping groove 2 4, thus pressing the rope end in the wire rope clamping groove 2 4 to prevent the rope core from slipping out of the wire rope clamping groove 2 4 during actual operation. This ensures the strength of the wire rope and also improves the strength of the conveyor belt. It should be noted that the opening 7 provides sufficient space for the multiple adapter ends 5 to contract and move when the locking rings 8 are tightened, ensuring that the multiple adapter ends 5 can further fix the wire rope and further improve the strength of the wire rope after connection. The entire repair process is simple and easy to operate, and takes little time. The repair is quick and efficient, with minimal damage to the conveyor belt, allowing it to continue operating and reducing repair costs. The positioning holes 9 and 10 are designed so that when the two sleeves 1 are mated, the positioning blocks 10 insert into the corresponding positioning holes 9, thus positioning the two sleeves 1 for easy assembly and facilitating repair work. The external thread 6 and internal thread 13 are mutually compatible; when the locking ring 8 is installed, the external thread 6 and internal thread 13 will mesh together. This secures the locking ring 8 to the adapter end 5 and the sleeve 1, allowing the broken wire ropes to be firmly connected. The wire rope hole 14 is formed by casting a rubber strip 12 onto the wire rope core 11, making it easier and more convenient to peel off the rubber strip 12, thus facilitating the user's repair work. The structure design with an external joint allows the two broken wire ropes to be reconnected, forming a complete wire rope. The threaded locking method also ensures the strength of the wire rope, thereby improving the strength of the conveyor belt after repair. The repair work is convenient, quick, low-cost, and fast. Finally, the cut-off part is filled with rubber material.

[0027] Multiple positioning holes 9 are provided at one end of one side of the clamp 1, and multiple positioning blocks 10 are fixedly connected to one end of one side of the clamp 1. The positioning holes 9 and positioning blocks 10 on the two clamps 1 are compatible with each other.

[0028] Specifically, the positioning hole 9 and the positioning block 10 are designed so that when the two sleeves 1 are engaged, the positioning block 10 is inserted into the corresponding positioning hole 9, thereby positioning the two sleeves 1 during engagement and providing convenience for the user's repair work.

[0029] One side of the clamp 1 is provided with multiple wire rope cores 11, one of which is engaged in two clamps 1.

[0030] Rubber strips 12 are cast on the surface of multiple steel wire rope cores 11.

[0031] The surface of the adapter end 5 is provided with an external thread 6, and the inner side of the locking ring 8 is provided with an internal thread 13 that is adapted to the external thread 6.

[0032] Specifically, the external thread 6 and the internal thread 13 are mutually compatible. When the locking ring 8 is installed, the external thread 6 and the internal thread 13 will mesh together, thereby fixing the locking ring 8 on the adapter end 5 and the sleeve 1, thus enabling the broken wire rope to be firmly connected together.

[0033] The inner side of the rubber belt 12 forms a wire rope hole 14 based on the wire rope core 11.

[0034] Specifically, the wire rope hole 14 is formed by casting a rubber strip 12 on the wire rope core 11. Therefore, it is easier and more convenient to peel off the rubber strip 12, which provides convenience for the user's repair work.

[0035] In summary, this steel wire rope core conveyor belt repair joint, through its structural design of adding an external joint, can reconnect the two broken steel wire ropes together to form a complete steel wire rope. Furthermore, the threaded locking method ensures the strength of the steel wire rope, thereby improving the strength of the repaired conveyor belt. The repair work is convenient, quick, low-cost, and fast.

[0036] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
