Description

Technical Field

[0001] The invention relates to the technical field of industrial protective equipment, and in particular to a buffer device for a belt conveyor weight tensioning device. Background Art

[0002] In the field of modern industrial production and material transportation, belt conveyors are widely used due to their many advantages such as large conveying capacity, high efficiency, and stable operation. The tensioning device provides tension for the belt conveyor to prevent slipping between the conveyor belt and the drive roller, and to prevent the conveyor belt from sag too much between the rollers, causing material to be scattered. Among them, the heavy hammer tensioning device is the most widely used in conveyors due to its fast response speed and high reliability.

[0003] Traditional designs often focus on providing the tensioning force of the heavy hammer, but ignore the absorption and buffering of impact energy, which makes it difficult to adapt to the strict requirements of modern industry for belt conveyors to operate efficiently, stably and for a long life.

[0004] Some belt conveyors have long tensioning strokes and heavy weights. When the conveyor belt breaks or other emergencies occur, the suspended heavy weight tensioning device will fall freely. If the tensioning device is placed on the floor of the transfer station, it may damage or even penetrate the floor, causing damage to the floor or the heavy weight tensioning device, and may also cause safety accidents. Repairing these parts requires a lot of manpower, material resources and time costs.

[0005] At present, there is no buffer device for the heavy hammer tensioning device. Summary of the invention

[0006] According to the technical problems raised above, a buffer device for a belt conveyor weight tensioning device is provided. When the weight falls, the weight can be supported by a steel wire rope to prevent it from directly impacting the floor slab, etc. The impact energy of the falling weight can be converted into the elastic potential energy of the spring through the steel wire rope, which reduces the impact on the transfer station floor slab, etc. and the probability of safety accidents, improves the overall performance and reliability of the belt conveyor, reduces the operation and maintenance costs and failure risks of the equipment, and promotes the further development and application of belt conveyor technology in the industrial field.

[0007] The technical means adopted by the present invention are as follows:

[0008] A buffer device for a belt conveyor weight tensioning device, comprising:

[0009] Mining wire rope has flexibility and elastic deformation ability. When subjected to the impact load of the heavy hammer device, it absorbs part of the energy through its own elastic deformation, and transmits the tensile force generated by the impact load from the force point to the torsion spring through the rope ring and the tension-torsion conversion plate in sequence;

[0010] Rope clamps are used to fix mining wire ropes on rope rings, prevent mining wire ropes from escaping from rope rings and make the mining wire ropes evenly stressed on the rope rings;

[0011] The rope ring is used as a connection point to connect the mining steel wire rope and the tension-torsion conversion plate to bear and transmit the tension from the mining steel wire rope;

[0012] The tension-torsion conversion plate is in contact with the rope ring, the linkage tube, the torsion spring, and the spring sleeve, and is used to transfer the tension of the rope ring to the torsion spring and serve as a support for the linkage tube and the torsion spring;

[0013] The torsion spring is used to twist when receiving the remaining part of the impact load transmitted by the mining wire rope, rope ring, and tension-torsion conversion plate, so as to store the impact energy and play a buffering role;

[0014] The linkage tube is installed on each tension-torsion conversion plate, so that each tension-torsion conversion plate is connected in series and deflects at the same angle when subjected to load, so that each torsion spring stores the same energy;

[0015] The spring sleeve is used for the torsion spring and the tension-torsion conversion plate to be mounted on the support plate, and has split pins on both sides to prevent it from being separated from the support plate;

[0016] A support plate, connected to the torsion spring and the spring sleeve, is used to fix the torsion spring, bear force and transmit force;

[0017] The support frame is connected to the support plate and plays a supporting and force transmission role;

[0018] The hydraulic damper is installed at the bottom of the support frame. It realizes the damping effect by the movement of the damping piston in the damping cylinder. When the device is impacted or vibrated, it generates corresponding damping force according to the force size and speed to absorb and dissipate energy and enhance the buffering performance.

[0019] Furthermore, there are multiple rope clamps, which are evenly distributed along the fixed positions of the mining steel wire rope on the rope ring.

[0020] Furthermore, a detachable connection structure is adopted between the linkage tube and the tension-twist conversion plate.

[0021] Furthermore, a seal is provided between the spring sleeve and the support plate to prevent dust and other impurities from entering and affecting the performance of the device.

[0022] Furthermore, the damping force of the hydraulic damper can be adjusted to meet the buffering requirements of different impact loads.

[0023] Furthermore, a wear-resistant bushing is provided at the connection position between the pull-twist conversion plate and the rope ring to reduce wear.

[0024] Furthermore, the connection angle between the support frame and the support plate can be adjusted to optimize the force transmission direction.

[0025] Furthermore, the surface of the mining steel wire rope is coated with an anti-corrosion coating to improve its durability in the mining environment.

[0026] The conduction process of the impact load of the present invention using the above technical solution is as follows: when the impact load acts on the mining steel wire rope, the mining steel wire rope will pull the rope ring, thereby driving the tension-torsion conversion plate, and the rotation of the tension-torsion conversion plate will drive the torsion spring to rotate. The linkage tube will ensure that each tension-torsion conversion plate rotates at the same angle, that is, all springs are twisted at the same angle. The deformation of a single torsion spring will cause the support plate where it is located to bear forces in both horizontal and vertical directions. For the support frame, because the number of torsion springs and support plates on the left and right sides is the same, the forces in the horizontal direction cancel each other out, and only the forces in the vertical direction are borne. The vertical load is absorbed by the hydraulic damper.

[0027] A method for installing a buffer device for a belt conveyor weight tensioning device comprises the following steps:

[0028] Step 1: Install the torsion spring between the pair of support plates according to the distance between the pair of support plates determined by the design, and then weld the pair of support plates to the support frame mainly composed of channel steel;

[0029] Step 2: Place the pull-twist conversion plate inside each torsion spring, pass the spring sleeve through each support plate, the pull-twist conversion plate and the torsion spring in sequence, and insert a split pin at the end of the spring sleeve to prevent the spring sleeve from detaching from the support plate;

[0030] Step 3: Put the rope ring on the tension-twist conversion plate, then put the mining wire rope on the rope ring, and clamp the mining wire rope on the rope ring according to the clamping position determined by the design through the rope clamp;

[0031] Step 4: Use steel to weld the support frame, select the corresponding steel model according to the weight of the heavy hammer, determine the size of the support frame according to the size of the heavy hammer, and weld the damper guide tube at the bottom of the bracket;

[0032] Step 5: Fix the hydraulic damper with its own support to the ground with bolts;

[0033] Step 6: Lift the support frame to the upper part of the hydraulic damper, adjust the relative position of the support frame and the damper, and then put the support frame damper guide tube into the damper to complete the installation of the damper and the support frame.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] 1. Efficient buffering: Through the synergistic effect of elastic buffer elements and damping elements, the impact energy generated by the heavy hammer tensioning device during the falling process can be effectively absorbed and dissipated, greatly reducing the impact of the impact on the external environment.

[0036] 2. Extend equipment life: effectively reduce the damage caused by impact between the heavy hammer tensioning device and the floor slab, extend the service life of the tensioning device, reduce maintenance costs and replacement frequency, and improve production efficiency.

[0037] 3. Its evenly distributed rope clamps make the wire rope connection more stable and ensure the reliability of the overall structure. The detachable connection between the linkage tube and the tension-torsion conversion plate facilitates maintenance and repair, reducing operating costs. The seal between the spring sleeve and the support plate effectively blocks dust and impurities, ensuring the cleanliness of the inside of the device and extending its service life. The damping force of the hydraulic damper is adjustable, which can accurately respond to different impact loads and improve the adaptability of the buffering effect. The wear-resistant bushing reduces the wear of the connection between the tension-torsion conversion plate and the rope ring, and enhances durability. The connection angle between the support frame and the support plate can be adjusted to optimize the force transmission direction and improve the stability and buffering efficiency of the device. The anti-corrosion coating of the wire rope enhances its corrosion resistance in harsh mining environments, further improving the reliability, safety and service life of the overall device in the field of mining machinery and industrial protection, and ensuring the stable operation of related equipment.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0047] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0048] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.

[0051] like Figures 1 to 4 As shown, the present invention provides a buffer device for a belt conveyor weight tensioning device, comprising:

[0052] The mining wire rope 1 has flexibility and elastic deformation capability, and is used to absorb part of the energy through its own elastic deformation when subjected to the impact load of the heavy hammer device, and transmit the tensile force generated by the impact load from the force point to the torsion spring 5 through the rope ring 3 and the tension-torsion conversion plate 4 in sequence;

[0053] The rope clamp 2 is used to fix the mining steel wire rope 1 on the rope ring to prevent the mining steel wire rope 1 from escaping from the rope ring and to make the mining steel wire rope 1 evenly stressed on the rope ring. A U-shaped rope clamp, a wedge sleeve or a plow-shaped wedge sleeve can be used.

[0054] The rope ring 3 is used as a connection point to connect the mining steel wire rope 1 and the tension-torsion conversion plate to bear and transmit the tension from the mining steel wire rope 1;

[0055] The tension-torsion conversion plate 4 is in contact with the rope ring 3, the linkage tube 6, the torsion spring 5, and the spring sleeve 7, and is used to transfer the tension of the rope ring 3 to the torsion spring 5 and serve as a bracket for the linkage tube 6 and the torsion spring 5;

[0056] The torsion spring 5 is used to twist when receiving the remaining part of the impact load transmitted by the mining steel wire rope 1, the rope ring 3, and the tension-twist conversion plate 4, so as to store the impact energy and play a buffering role;

[0057] The linkage tube 6 is installed on each tension-torsion conversion plate 4, so that each tension-torsion conversion plate 4 is connected in series and deflects at the same angle when subjected to a load, so that each torsion spring 5 stores the same energy;

[0058] The spring sleeve 7 is provided with a sleeve for the torsion spring 5 and the tension-twist conversion plate 4, and is installed on the support plate 8, and has split pins on both sides to prevent it from being separated from the support plate 8;

[0059] A support plate 8 is connected to the torsion spring 5 and the spring sleeve 7, and is used to fix the torsion spring 5, bear force and transmit force;

[0060] The support frame 9 is connected to the support plate 8 and plays a supporting and force transmission role;

[0061] The hydraulic damper 10 is installed at the bottom of the support frame 9, and realizes the damping effect by the movement of the damping piston in the damping cylinder. When the device is impacted or vibrated, the corresponding damping force is generated according to the force size and speed to absorb and dissipate energy, thereby enhancing the buffering performance.

[0062] Furthermore, the number of the rope clamps is multiple and evenly distributed along the fixed position of the mining steel wire rope 1 on the rope ring 3. For example, five rope clamps are used to fix the connection position of the mining steel wire rope 1 on the rope ring 3. The rope clamps are made of high-strength alloy steel. The tightening torque of the nut of each rope clamp reaches 150N·m, which effectively prevents the mining steel wire rope 1 from slipping when subjected to impact load.

[0063] Furthermore, a detachable connection structure is adopted between the linkage tube 6 and the tension-twist conversion plate 4. For example, the linkage tube 6 and the tension-twist conversion plate 4 are connected by bolts to realize a detachable structure. A connecting flange is welded at one end of the linkage tube 6, and four bolt holes with a diameter of 12 mm are evenly distributed on the flange. The tension-twist conversion plate 4 also has bolt holes of the same specification at the corresponding positions, which are connected with M10 high-strength bolts with a length of 40 mm and are equipped with flat washers and spring washers. When the linkage tube 6 or the tension-twist conversion plate 4 needs to be repaired or replaced, the two can be separated by simply removing the bolts, which is convenient and quick, and improves the maintainability of the device.

[0064] Furthermore, a seal is provided between the spring sleeve 7 and the support plate 8 to prevent dust and other impurities from entering and affecting the performance of the device. For example, a rubber seal ring is used as a seal ring, and the material of the rubber seal ring is nitrile rubber, which has good oil resistance, wear resistance and aging resistance. The cross-sectional shape of the seal ring is circular, with a diameter of 5mm, and is installed in the annular groove at the bottom of the spring sleeve 7 and the support plate 8. The groove depth is 3mm and the width is 4mm. The seal ring is slightly higher than the groove plane. After the spring sleeve 7 and the support plate 8 are assembled, the seal ring is compressed to form a tight seal, which effectively blocks dust, rock powder and other impurities in the mine from entering the spring sleeve 7, ensuring that the spring works in a clean environment, extending the service life of the spring and ensuring the performance stability of the buffer device.

[0065] Furthermore, the damping force of the hydraulic damper 10 can be adjusted to meet the buffering requirements of different impact loads. The hydraulic damper 10 adopts a structure with an adjustable throttle valve. The throttle valve is installed on the oil channel of the damper. By rotating the adjustment knob of the throttle valve, the flow cross-sectional area of ​​the oil can be changed, thereby adjusting the damping force. For example, under normal operating conditions, the throttle valve is adjusted to a smaller opening so that the hydraulic damper 10 provides a smaller damping force to reduce the resistance to the operation of the equipment; the adjustment range of the throttle valve can make the damping force continuously change between 10kN-50kN to meet the buffering requirements under different working conditions.

[0066] Furthermore, a wear-resistant bushing is provided at the connection part between the pull-twist conversion plate 4 and the rope ring 3 to reduce wear. The wear-resistant bushing is made of bronze, and the inner diameter of the bushing matches the diameter of the rope ring 3, with a tolerance of ±0.1 mm. The outer diameter is designed according to the size of the connection hole of the pull-twist conversion plate 4, and the thickness is 5 mm. After the wear-resistant bushing is installed in the connection hole of the pull-twist conversion plate 4, the rope ring 3 passes through the bushing and is connected to the pull-twist conversion plate 4. The bushing made of bronze has good wear resistance and self-lubrication. During the relative movement between the rope ring 3 and the pull-twist conversion plate 4, the friction coefficient is effectively reduced, and wear is reduced.

[0067] Furthermore, the connection angle between the support frame 9 and the support plate 8 can be adjusted to optimize the force conduction direction. The support frame 9 and the support plate 8 are connected by a hinge and are equipped with an angle adjustment bolt. The hinge is made of alloy steel and can withstand large shear forces. An angle adjustment bolt is installed on each side of the hinge. The bolt passes through the arc-shaped long holes on the support frame 9 and the support plate 8, and the center of the circle is located at the center of the hinge pin. By rotating the adjusting bolt, the angle between the support frame 9 and the support plate 8 can be changed, and the angle adjustment range is 30°-150°. The buffer device can better withstand and transmit impact force, thereby improving the stability and reliability of the entire system.

[0068] Furthermore, the surface of the mining steel wire rope 1 is coated with an anti-corrosion coating to improve its durability in the mining environment. A hot-dip galvanized coating is used as the anti-corrosion coating of the mining steel wire rope 1. The thickness of the hot-dip galvanized coating reaches 80 μm and evenly covers the surface of the mining steel wire rope 1. In the harsh environment of the mine, such as humidity and acidic gas, the hot-dip galvanized layer can effectively prevent the mining steel wire rope 1 from rusting and corrosion. The hot-dip galvanized coating significantly improves the durability of the mining steel wire rope 1 in the mining environment and reduces maintenance costs and safety risks.

[0069] The transmission process of the impact load of the present invention using the above technical solution is as follows: when the impact load acts on the mining steel wire rope 1, the mining steel wire rope 1 will pull the rope ring 3, and then drive the tension-torsion conversion plate 4, and the rotation of the tension-torsion conversion plate 4 will drive the torsion spring 5 to rotate. The linkage tube 6 will ensure that each tension-torsion conversion plate 4 rotates at the same angle, that is, all springs are twisted at the same angle. The deformation of a single torsion spring 5 will cause the support plate 8 where it is located to bear forces in both horizontal and vertical directions. Because the number of torsion springs 5 ​​and support plates 8 on the left and right sides of the support frame 9 is the same, the horizontal forces cancel each other out, and only the vertical force is borne. The vertical load is absorbed by the hydraulic damper.

[0070] A method for installing a buffer device for a belt conveyor weight tensioning device comprises the following steps:

[0071] Step 1: Install the torsion spring 5 between the pair of support plates 8 according to the distance between the pair of support plates 8 determined by the design, and then weld the pair of support plates 8 to the support frame 9 mainly made of channel steel;

[0072] Step 2: Place the pull-twist conversion plate 4 inside each torsion spring 5, pass the spring sleeve 7 through each support plate 8, the pull-twist conversion plate 4 and the torsion spring 5 in sequence, and insert a split pin at the end of the spring sleeve 7 to prevent the spring sleeve 7 from detaching from the support plate 8;

[0073] Step 3: Put the rope ring 3 on the tension-twist conversion plate 4, then put the mining wire rope 1 on the rope ring 3, and clamp the mining wire rope 1 on the rope ring 3 according to the clamping position determined by the design through the rope clamp;

[0074] Step 4: Use steel to weld the support frame 9, select the corresponding steel model according to the weight of the heavy hammer, determine the size of the support frame 9 according to the size of the heavy hammer, and weld the damper guide tube at the bottom of the bracket;

[0075] Step 5: Fix the hydraulic damper 10 with its own support on the ground by bolts;

[0076] Step 6: hoist the support frame 9 to the upper part of the hydraulic damper 10, adjust the relative position of the support frame 9 and the damper, and then put the damper conduit of the support frame 9 into the damper to complete the installation of the damper and the support frame 9.

[0077] Finally, it should be noted that 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
