Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a high-strength conveyor belt for coal mines. Background Technology

[0002] Mining conveyor belts are the key load-bearing and traction structures of belt conveyors. They are mostly made of steel wire rope or canvas as the core and covered with wear-resistant rubber on the outside. They can adapt to the conveying needs of bulk materials such as coal and ore. They can achieve cyclic operation through roller drive and can convey materials horizontally, inclined or even vertically. They can adapt to long-distance and large-volume operation scenarios. Because mining conveyor belts are relatively long, they need to be secured at one end using fasteners or buckles. For example, the Chinese utility model patent CN221145170U discloses a conveyor belt buckle. This application uses a U-shaped structure formed by bending a steel plate. The U-shaped conveyor belt buckle has an arc-shaped section and mounting sections at both ends of the arc-shaped section for installing U-shaped pins. The outer wall of the conveyor belt buckle has a protrusion along its length. When two conveyor belts are connected, the belt must overcome its own weight, the weight of the material, and the resistance from roller friction and inclined conveying. The inertia during starting and braking also generates tensile force on the belt. Therefore, this application uses pins with a small cross-section to penetrate the conveyor belt, concentrating the force at the connection hole. Under long-term tensile stress, the conveyor belt is prone to tearing at the hole. Furthermore, when several conveyor belt buckles are used in a row, insufficient overall integrity can lead to uneven stress, and individual buckles at the joint may loosen or deform, affecting the transmission of tensile force and reducing the joint strength and stability. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength conveyor belt for coal mines, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-strength fastening conveyor belt for coal mines includes a conveyor belt, one end of which is fixedly connected to a connecting buckle. The connecting buckle also includes several clamping plates. Several arc-shaped buckles are fixedly connected to one end of two adjacent clamping plates. Each of the two clamping plates has a locking groove at one opposite end. A locking plate is inserted into the locking groove. Several positioning blocks are fixedly connected to the lower end of the locking plate. A connecting nail is fixedly connected to the lower end of the positioning block. A through-hole is formed in the positioning block and the locking plate near the connecting nail.

[0005] As a further preferred embodiment of this utility model, several arc-shaped buckles of two connecting buckles on opposite sides are interlocked and connected to each other, and a connecting shaft is interlocked between several arc-shaped buckles, so that a strong connection can be achieved by setting several connecting buckles at one end of the two conveyor belts in conjunction with the connecting shaft.

[0006] As a further preferred embodiment of this utility model, one of the clamping plates has several countersunk holes, and the other clamping plate has a screw hole. The two clamping plates are inserted into the upper and lower positions of the conveyor belt by several arc-shaped buckles. A fixing screw is inserted into the countersunk hole, and one end of the fixing screw passes through the conveyor belt and is threaded into the screw hole. This makes it easy to disassemble and maintain the clamping plates after they are fixed to one end of the conveyor belt.

[0007] As a further preferred embodiment of this utility model, the engaging groove is provided with a plurality of semi-circular positioning grooves to provide installation conditions for the positioning block.

[0008] As a further preferred embodiment of this utility model, a plurality of slots are provided on the outer side of the connecting nail away from the positioning block, and a plurality of retaining rings are fixedly connected in the connecting hole. The positioning block is inserted into two adjacent semi-circular positioning slots, and one end of the connecting nail is inserted into the connecting hole of the positioning block opposite to the mounting carrier. The slots and retaining rings are engaged with each other. After two adjacent clamping plates are connected to the plurality of semi-circular positioning slots through a locking plate, the anti-displacement ability of the clamping plates can be improved, thereby enhancing the connection rigidity and integrity between the clamping plates.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, the two clamping plates of the connecting buckle are installed by fixing screws, which not only ensures a tight fit with the belt body, but also facilitates subsequent disassembly and maintenance. The snap-fit ​​design of the snap-fit ​​plate and the positioning block enhances the integrity and connection rigidity of the multiple clamping plates, avoids loosening and deformation caused by uneven force, and disperses the stress at the connection hole of the conveyor belt, reducing the risk of tearing at the connection of the conveyor belt.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] like Figures 1-4 As shown, this utility model provides a high-strength coal mine conveyor belt, including a conveyor belt 1, one end of which is fixedly connected to a connecting buckle 2. The connecting buckle 2 also includes several clamping plates 3. Two adjacent clamping plates 3 are fixedly connected to several arc-shaped buckles 4 at one end. The two clamping plates 3 are respectively provided with locking grooves 5 at opposite ends. Locking plates 6 are inserted and connected in the locking grooves 5. Several positioning blocks 7 are fixedly connected to the lower end of the locking plates 6. Connecting nails 8 are fixedly connected to the lower end of the positioning blocks 7. Through-hole connecting holes 9 are provided in the positioning blocks 7 and the locking plates 6 near the connecting nails 8.

[0014] like Figure 1 As shown, several arc-shaped buckles 4 of the two connecting buckles 2 on opposite sides are interlocked and connected to each other, and a connecting shaft 15 is interlocked between the several arc-shaped buckles 4, so that a strong connection can be achieved by setting several connecting buckles 2 at one end of the two conveyor belts 1 in conjunction with the connecting shaft 15.

[0015] like Figures 2-4 As shown, one clamping plate 3 has several countersunk holes 10, and the other clamping plate 3 has screw holes 11. The two clamping plates 3 are inserted above and below the conveyor belt 1 by several arc-shaped buckles 4. A fixing screw is inserted into the countersunk hole 10, and one end of the fixing screw passes through the conveyor belt 1 and is threaded into the screw hole 11. This method of fixing the two clamping plates 3 to one end of the conveyor belt 1 facilitates subsequent disassembly and maintenance. The engaging groove 5 has several semi-circular positioning grooves 12 to provide installation conditions for the positioning block 7. Several slots 13 are provided on the outer side of the connecting nail 8 away from the positioning block 7. Several retaining rings 14 are fixedly connected in the connecting hole 9. The positioning block 7 is inserted into two adjacent semi-circular positioning slots 12. One end of the connecting nail 8 is inserted into the connecting hole 9 of the positioning block 7 opposite to the mounting carrier. The slots 13 and retaining rings 14 are engaged with each other. After two adjacent clamping plates 3 are connected to several semi-circular positioning slots 12 through the clamping plate 6, the anti-displacement ability of the clamping plates 3 can be improved, and the connection rigidity and integrity between several clamping plates 3 can be enhanced.

[0016] It should be noted that this utility model is a high-strength conveyor belt for coal mines. Before connecting two sections of conveyor belt 1, the two clamps 3 of the connecting buckle 2 are respectively attached to the upper and lower surfaces of the two sections of conveyor belt 1. The fixing screw in the countersunk hole 10 passes through the conveyor belt 1 and is threadedly locked with the screw hole 11 of the other clamp 3, so that the clamp 3 is tightly attached to the conveyor belt 1. Then, several connecting buckles 2 are installed on one end of the same conveyor belt 1 in the same manner as above. Then, the locking plate 6 is embedded into the two locking grooves 5 of the adjacent clamp 3 above, so that the positioning block 7 is inserted. Insert the two semi-circular positioning grooves 12 into the two semi-circular positioning grooves 12, and insert the other clamping plate 6 into the clamping grooves 5 of the two adjacent clamping plates 3 below in the same way as above. At the same time, insert the connecting nail 8 into the connecting hole 9 of the opposite positioning block 7, so that the outer groove 13 of the connecting nail 8 and the retaining ring 14 in the connecting hole 9 engage with each other, thus completing the overall fixation of multiple clamping plates 3. Then, install the connecting buckle 2 on one end of another section of conveyor belt 1 in the same way as above. Finally, interlock the arc buckles 4 of the connecting buckles 2 on opposite sides of the two sections of conveyor belt 1, and then insert the connecting shaft 15 into several arc buckles 4. When the conveyor belt 1 is running, the roller drives the belt body to circulate. The forces of material gravity, belt body weight, frictional resistance and inertial tension during operation are transmitted to the connecting buckle 2 through the conveyor belt 1. After the clamping plate 3 bears the force, the tension is dispersed by the cooperation of the arc buckle 4 and the connecting shaft 15. The locking plate 6 and the positioning block 7 improve the integrity of several connecting buckles 2 through the locking structure of the semi-circular positioning groove 12 and the locking ring 14 and the locking groove 13, so that the force is evenly distributed throughout the joint area and the local stress concentration is reduced.
