Under the action of strong winds, the belt will generate large swings and vibrations, increasing the load and stress of the system and seriously affecting the operation stability and safety. In addition, the fixed bracket structure cannot optimize the load distribution according to different wind force conditions and is prone to causing local bracket overload. Summary of the Invention:

Detailed implementation method:

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1 、 Figure 2 shown, a cable belt conveyor includes two fixing frames 1 fixedly arranged in sequence from top to bottom. A cable belt conveyor body is fixedly connected between the two fixing frames 1. The two ends of the cable belt conveyor body are respectively fixedly provided with a feeding end and a discharging end. A driving device is also arranged at the feeding end, and the driving device can drive the cable belt conveyor body to operate. The cable belt conveyor body includes a conveyor belt 2 arranged in parallel up and down. The conveyor belt 2 sequentially penetrates through a plurality of support frames 4. The support frames 4 and the conveyor belt 2 are slidably connected through a limiting sliding assembly 10. The top of the support frame 4 and the positioning frame 9 are slidably connected through a limiting sliding assembly 10. The limiting sliding assembly 10 can limit the support frame 4. The bottom of the support frame 4 is fixedly connected with a counterweight 6 through bolts. The counterweight 6 can increase the overall gravity of the support frame 4. An adjusting assembly 7 is fixedly connected between two adjacent support frames 4. The adjusting assembly 7 can adjust the distance between two adjacent support frames 4.

[0024] During use, a suitable counterweight 6 is installed at the bottom of the support frame 4 to increase the overall gravity of the support frame 4, so that the overall gravity of the support frame 4. At the same time, the adjustment component 7 can be used to adjust the distance between adjacent support frames 4 to enhance the wind resistance. Increasing the gravity of the support frame 4 can improve the stability of the entire conveying system, reduce the impact of wind on the conveyor belt. Reasonably adjusting the distance between the support frames can optimize the overall structure and further enhance the wind resistance performance; improve the conveying efficiency. A stable conveying system can ensure the smooth operation of the conveyor belt, reduce the conveying interruption caused by the influence of wind, and improving the wind resistance performance can ensure the continuity and reliability of the conveying process, thereby improving the overall conveying efficiency; extend the service life. The improvement of the wind resistance performance can reduce the wear and damage of the conveying system caused by the influence of wind, extend the service life of the conveying system, and reduce the maintenance and replacement costs; applicable to harsh environments. This solution can enable the cable belt conveyor to still operate stably in high-wind environments, expand the application range, and in harsh weather conditions, the conveyor can still work normally, improving the adaptability of the system.

[0025] As Figure 2 、 Figure 3 shown, a limit sliding component 10 is fixedly connected to the top of the support frame 4, and the limit sliding component 10 is sleeved on the positioning frame 9, and the limit sliding component 10 and the positioning frame 9 are slidable;

[0026] The limit sliding component 10 is fixedly connected to the support frame 4 through a fixing plate. A steel cable 13 can be fitted and embedded on the limit sliding component 10, and the limit sliding component 10 and the steel cable 13 are slidable;

[0027] The limit sliding component 10 includes a limit sliding sleeve, and an electromagnet is fixed on the inner side surface of the limit sliding sleeve. The electromagnet can adsorb the positioning frame 9 and can adsorb the steel cable 13;

[0028] The adjustment component 7 includes a bidirectional electric telescopic rod 12, and the bidirectional electric telescopic rod 12 is fixed between adjacent support frames 4;

[0029] The bidirectional electric telescopic rod 12 and the electromagnet are respectively connected to the controller in a controlled electrical manner.

[0030] During use, the controller is used to control the start or stop of the electromagnet, so that the limit sliding component 10 can be positioned or slid, thereby changing the distance between adjacent support frames 4. That is, when the electromagnet stops, the limit with the positioning frame 9 and the steel cable 13 is released, so that the limit sliding component 10 can slide. Then, the bidirectional electric telescopic rod 12 is controlled to start, and by the telescopic of the output end of the bidirectional electric telescopic rod 12, the distance between adjacent support frames 4 can be changed. After the adjustment is completed, the electromagnet can be started to generate an adsorption force to adsorb the positioning frame 9 and can adsorb the steel cable 13 to complete the positioning of the support frame 4.

[0031] The conveyor belt 2 includes a belt and side edges. The side edges are fixedly connected to both sides of the belt respectively. The cross-section of the belt includes an arc surface and a wavy surface. The wavy surfaces are fixedly arranged on both sides of the arc surface. The wavy surface has a certain elasticity, and a plurality of ventilation holes are fixed on the wavy surface. A mesh plate is fixed in the ventilation holes, and the inner side surface of the side edge is arranged in a fish scale shape;

[0032] During the use process, by means of the arrangement of the wavy surface, the friction with the conveyed material can be increased, the stability of the conveyed material can be improved. At the same time, the wavy surface has a certain elasticity, and the gravity of the material can be concentrated, so that the wavy surface is stretched, the ventilation holes can be opened, and air flow is generated to dry the material or for other purposes;

[0033] At the same time, because the inner side surface of the side edge is arranged in a fish scale shape, the friction between the side edge and the material can be effectively increased, so that the material is more stable during the conveying process and is not easy to slide or scatter. During the cableway conveying process, due to the large inclination angle and vibration, the reliability of the material conveying can be better improved. At the same time, it can also guide the material to flow more smoothly and reduce the accumulation and blockage of the material at the side edge.

[0034] A plurality of roller members 14 are rotatably connected to both sides of the conveyor belt 2 at equal intervals through connecting components, and the roller members 14 are rotatably arranged on the steel cable 13;

[0035] Such as Figure 3 、 Figure 4 、 Figure 5 As shown, the roller member 14 includes a cylinder body 15 and a rotating shaft 16. Retaining rings 17 are fixedly sleeved on both sides of the cylinder body 15 respectively. The steel cable 13 can be embedded between the two retaining rings 17, and the steel cable 13 is arranged in contact with the surface of the cylinder body 15. And an arc-shaped solar panel 18 is fixedly connected to the side surface of one of the retaining rings 17 through a connecting ring. One end of the rotating shaft 16 sequentially penetrates through the retaining ring 17, the cylinder body 15 and the arc-shaped solar panel 18 and is fixedly connected to the limiting ring. The other end of the rotating shaft 16 is inserted into the connecting component and is rotatably connected to the connecting component, and the connecting component is fixed on the side surface of the conveyor belt 2;

[0036] Because the length of the conveyor belt 2 is relatively long during the cableway conveying process, and a plurality of roller members 14 are provided, the arc-shaped solar panels 18 on each roller member 14 can absorb solar energy and store it to achieve energy recovery;

[0037] A plurality of elastic protrusions 19 are fixedly arranged annularly on the surface of the cylinder body 15, and barbs 20 are arranged between adjacent elastic protrusions. Burrs are fixed on the barbs. The barbs 20 can penetrate into the steel cable 13. During use, the plurality of elastic protrusions 19 can achieve point contact between the steel cable 13 and the cylinder body 15, reducing friction. At the same time, the barbs 20 can penetrate into the steel cable 13, enabling the burrs to have a certain effect on the steel cable 13, forming a certain adsorption effect, and increasing the stability of the idler member 14;

[0038] A plurality of limiting components 21 are fixedly arranged annularly and uniformly on the inner side surface of the retaining ring 17. The limiting components 21 can both limit the steel cable 13 and reduce the friction with the steel cable 13;

[0039] The limiting component 21 includes a limiting groove 22, a limiting plate 23, a wedge-shaped rubber plate 24 and an arc-shaped silica gel plate 25. The limiting plate 23 is hinged in the limiting groove 22 through a hinge shaft. The side surface of the limiting plate 23 protrudes from the limiting groove 22. A wedge-shaped rubber plate 24 is fixed between the other side surface and the inner side surface of the limiting groove 22. In the initial state, the wedge-shaped rubber plate 24 can push the limiting plate 23 into an inclined state, and it is inclined from the edge of the retaining ring 17 to the surface of the cylinder body 15. At the same time, an arc-shaped silica gel plate 25 is fixed on the side surface of the limiting plate 23 close to the edge of the retaining ring 17. In this way, it does not affect the embedding of the steel cable 13 between the two retaining rings 17, and the steel cable 13 can exert a force on the limiting plate 23 by means of the arc-shaped silica gel plate 25, causing the limiting plate 23 to swing. The arc-shaped silica gel plate 25 forms a limiting effect on the steel cable 13. At the same time, the steel cable 13 can contact the side surface of the limiting plate 23 close to the cylinder body 15. Because a feather-shaped structure is arranged on the side surface of the limiting plate 23 here, the arrangement of the feather-shaped structure can increase the air flow between the limiting plate 23 and the steel cable 13, reducing the frictional resistance.

[0040] As Figure 6 shown, the connecting component includes two semi-circular pressing plates 26 with opposite inner arc surfaces, and the two semi-circular pressing plates 26 are fixedly connected through an arc-shaped connecting plate 27. Threaded rods are fixed on the semi-circular pressing plates 26, and locking nuts are screwed on the threaded rods. A through hole is fixed on the arc-shaped connecting plate 27, and the threaded rod can pass through the through hole in a fitting manner and be screwed with the locking nut.

[0041] A top limiting component 28 is further arranged at the upper end of the conveyor belt 2. The top limiting component 28 is fixed in the support frame 4. The top limiting component 28 can limit the top of the conveyor belt 2 to ensure the stability of the conveyor belt 2;

[0042] As Figure 3As shown in the figure, the top limiting assembly 28 includes two U-shaped limiting plates 29. The two U-shaped limiting plates 29 are respectively slidably clamped on the two edge guards of the conveyor belt 2. The top of the U-shaped limiting plate 29 is fixedly connected with a top limiting rod 30 through a connecting rod. The two ends of the top limiting rod 30 are respectively fixedly connected with limiting columns, and the limiting columns pass through the limiting through holes and extend into the side plates of the support frame 4 to be fixedly connected with the limiting sliding plate 31. The limiting sliding plate 31 is slidably arranged in the side plates of the support frame 4. During the use process, by using the two U-shaped limiting plates 29 and the top limiting rod 30, a top limiting force can be generated on the upper end of the conveyor belt 2 to ensure stable operation. At the same time, because the limiting sliding plate 31 slides out of the side plates of the support frame 4 and is fixedly connected with the counterweight 6 through bolts, the counterweight 6 includes a counterweight block 11. The counterweight block 11 can adopt counterweight blocks 11 with different gravities according to the actual use process. The outer diameter of the limiting column is slightly smaller than the inner diameter of the limiting through hole or a rubber ring is fixed between the limiting column and the limiting through hole. In this way, the force generated by the counterweight block 11 is transmitted through the top limiting rod 30, so that the two U-shaped limiting plates 29 can generate a downward pressing trend on the conveyor belt 2 to ensure the stable operation of the conveyor belt 2.

[0043] A method for enhancing the wind resistance of a cable belt conveyor is as follows:

[0044] Step 1: Fix and install the first anemometers 5 on the two fixing frames 1 respectively. At the same time, install the second anemometers 8 on each support frame 4. The second anemometers 8 are electrically connected to the controller for transmission. The controller is installed on the fixing frame 1.

[0045] Step 2: Use the first anemometers 5 to monitor the wind speeds at the highest and lowest points of the cable belt conveyor body to determine the load of the support frame 4, that is, the gravity of the counterweight 6.

[0046] Step 2-1: Take the average value matrix V0 of the data measured by the two first anemometers 5 multiple times.

[0047] Step 2-2: Set the wind pressure F. Without considering other influences of the support frame 4, set the load of the support frame 4 as G and the wind pressure as P.

[0048] According to the force balance and the relationship between the force on an object and its deformation, it can be obtained that: G = k * P, (k is a constant related to factors such as the bracket structure and material);

[0049] Based on Bernoulli's equation and the basic principles of fluid dynamics, it can be obtained that: P = 1 / 2 * ρ * V0 2 (ρ is the air density);

[0050] Comprehensively, it can be obtained that: G = k * 1 / 2 * ρ * V0 2；

[0051] Step 2-3: Set the average value matrix V0 (V1, V2, V3; V1 < V2 < V3);

[0052] When the wind speed is less than or equal to V1, the load on the support frame 4 is G1 = k * 1 / 2 * ρ * V1 2 ;

[0053] When the wind speed is greater than V1 and less than or equal to V2, the load on the support frame 4 is G2 = k * 1 / 2 * ρ * V2 2 ;

[0054] When the wind speed is greater than V2 and less than or equal to V3, the load on the support frame 4 is G3 = k * 1 / 2 * ρ * V3 2 ;

[0055] Without considering other factors, set V2 - V1 = N, V3 - V2 = N; (N is a fixed constant), the initial wind speed is V1, and the initial load on the support frame 4 is G1, then it can be obtained that G2 - G1 ≈ 4N, G3 - G2 ≈ 4N;

[0056] Step 3: Complete the installation of the load on each support frame 4, that is, install the counterweight 6 with an appropriate weight, and at the same time control the distance between adjacent support frames 4 to be H0;

[0057] During use, the load on each support frame 4 is constant. According to the multiple monitoring data of the second anemometer 8, the controller controls the adjustment component 7 to adjust the distance between adjacent support frames 4;

[0058] Step 4-1: The multiple monitoring data of the second anemometer 8 is fed back to the controller, and there is a wind speed matrix v0 in the controller;

[0059] Step 4-2: Set the distance H between adjacent support frames 4, the bending deformation amount of the cable belt is δ, and the wind pressure is p;

[0060] Based on the support principle in mechanics and the elastic deformation characteristics of the material, it can be obtained that: H = K / δ (K is a constant related to factors such as the cable belt material and cross-section);

[0061] Based on the mechanical principle, the characteristics of the cable belt structure, and Hooke's law, it can be obtained that: δ = m * p (m is a constant related to factors such as the cable belt structure and material);

[0062] Based on Bernoulli's equation and the basic principles of fluid dynamics, it can be obtained that: p = 1 / 2 * ρ * v0 2 (ρ is the air density);

[0063] Comprehensively, it can be obtained that: H = K / (m * 1 / 2 * ρ * v0 2 )

[0064] Step 4-3: Set the wind speed matrix v0 (V1, V2, V3; V1 < V2 < V3),

[0065] When the wind speed is less than or equal to V1, the distance between adjacent support frames 4 is H1 = K / (m * 1 / 2 * ρ * V1 2 ), and the controller controls the adjustment component 7 to make the distance between adjacent support frames 4 be H1;

[0066] When the wind speed is greater than V1 and less than or equal to V2, the distance between adjacent support frames 4 is H2 = K / (m * 1 / 2 * ρ * V2 2 ), and the controller controls the adjustment component 7 to make the distance between adjacent support frames 4 be H2;

[0067] When the wind speed is greater than V2 and less than or equal to V3, the distance between adjacent support frames 4 is H3 = K / (m * 1 / 2 * ρ * V3 2 ), and the controller controls the adjustment component 7 to make the distance between adjacent support frames 4 be H3;

[0068] Without considering other factors, set V2 - V1 = n, V3 - V2 = n; (n is a fixed constant), the initial wind speed is V1, and the distance between adjacent support frames 4 is H1. It can be obtained that H2 - H1 ≈ n / 4, H3 - H2 ≈ n / 4.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
