Description

Technical Field

[0001] The invention relates to the technical field of tubular belt conveyors, and in particular to a sound insulation device. Background Art

[0002] At present, the composition of tubular belt conveyors is basically the same as that of ordinary belt conveyors. They are also composed of driving parts, rollers, rollers, brackets, belts, belt conveyor protection, etc. The head and tail sections are exactly the same as ordinary belt conveyors. The difference is the transition section and the middle conveying section. The transition section is to gradually transition the belt from an ordinary trough to a sealed circle. The middle conveying section is to transport materials in a fully enclosed circle with the belt. The return journey of the belt is also the same.

[0003] In the prior art, tubular belt conveyors are usually used for long-distance transportation, which inevitably requires them to pass through residential areas. During the operation of tubular belt conveyors, especially when a large number of rollers are in operation, there is not only low-frequency noise generated by the friction of the rollers, but also high-frequency noise caused by the slapping of the belts and rollers due to the radial runout of the rollers. This makes sound insulation and noise reduction relatively difficult and easily brings negative impacts on the normal life of residential areas.

[0004] In order to solve the above noise problem, closed sound insulation walls (boards) are installed on both sides of the tubular belt conveyor to achieve better sound insulation and noise reduction effects. However, the above closed sound insulation walls (boards) not only make it more difficult for personnel to enter and exit the inspection equipment, but most importantly, if there is strong wind, the huge resistance caused by the closed sound insulation walls (boards) may cause the tubular belt conveyor to overturn as a whole, which will bring huge hidden dangers to its safety in use.

[0029] In order to solve the problem in the prior art that the sound insulation device affects the normal maintenance of the conveyor by the staff and even creates a safety hazard, the present application provides a sound insulation device.

[0030] like Figures 1 to 6 As shown, the sound insulation device includes a machine base 1 and a sound insulation component 3. The machine base 1 includes a top plate 101, a bottom plate 102 and a support plate 103. The top plate 101 is connected to the bottom plate 102 through the support plate 103. The support plate 103 has a first mounting hole 2 for mounting the conveyor belt of the tubular belt conveyor. The top plate 101, the bottom plate 102 and the support plate 103 surround and form a mounting opening, and the mounting opening is located on both sides of the conveyor belt. The sound insulation component 3 is arranged at the mounting opening. The sound insulation component 3 includes a first sound insulation structure 310, a second sound insulation structure 13 and at least two receiving structures 301. The receiving structure 301 is arranged on the support plate 103. The first end of the first sound insulation structure 310 is rotatably connected to one receiving structure 301. The second end of the first sound insulation structure 310 has an attraction state of magnetic attraction with another receiving structure 301 and a maintenance state of separation from the receiving structure 301. The first sound insulation structure has a second mounting hole, and the second sound insulation structure 13 can be movably disposed in the second mounting hole to block or avoid the second mounting hole.

[0031] The technical solution of this embodiment is applied, and the sound insulation device includes a machine base 1 and a sound insulation component 3. The machine base includes a top plate 101, a bottom plate 102 and a support plate 103. The top plate 101 is connected to the bottom plate 102 through the support plate 103. The support plate 103 has a first mounting hole 2 for mounting the conveyor belt of the tubular belt conveyor. The top plate 101, the bottom plate 102 and the support plate 103 surround and form a mounting opening, and the mounting opening is located on both sides of the conveyor belt. The sound insulation component 3 is arranged at the mounting opening. The sound insulation component 3 includes a first sound insulation structure 310, a second sound insulation structure 13 and at least two receiving structures 301. The receiving structure 301 is arranged on the support plate 103, and the upper end of the sound insulation structure is rotatably connected to one of the receiving structures 301. The first sound insulation structure 310 has a second mounting hole, and the second sound insulation structure 13 can be movably arranged in the second mounting hole to block or avoid the second mounting hole. In this way, the lower end of the first sound insulation structure 310 has an attraction state of being magnetically attracted to another receiving structure 301 and a maintenance state of being separated from the receiving structure 301. In the initial state, the first sound insulation structure 310 is in the attraction state, which plays a role in sound insulation and noise reduction for the conveyor belt; when the staff needs to maintain the conveyor belt, the first sound insulation structure 310 is operated to switch the first sound insulation structure 310 from the attraction state to the maintenance state, and the staff can maintain the conveyor belt through the installation port. Since the first sound insulation structure 310 and the receiving structure 301 are magnetically attracted and the second sound insulation structure 13 is movably arranged on the first sound insulation structure 310, if strong winds occur, the first sound insulation structure 310 can be separated from the receiving structure 301 under the action of wind, thereby reducing the resistance to the sound insulation structure to prevent the conveyor from overturning as a whole, and the second sound insulation structure 13 can rotate relative to the first sound insulation structure 310 under the action of wind to avoid the second mounting hole, thereby solving the problem in the prior art that the sound insulation device affects the normal maintenance of the conveyor by the staff and even creates a safety hazard, making it convenient for the staff to maintain the conveyor and reducing the safety hazard caused by the sound insulation device.

[0032] like Figure 2 As shown, the sound insulation assembly 3 further includes a rotating shaft 14. The rotating shaft 14 is disposed inside the first sound insulation structure 310, and the second sound insulation structure 13 is pivotally connected to the first sound insulation structure 310 via the rotating shaft 14.

[0033] like Figure 2 As shown, the second sound insulation structure 13 includes a panel 131 and a first sound insulation material 132. The panel 131 has a receiving cavity. The first sound insulation material 132 is arranged in the receiving cavity; the first sound insulation material 132 is sound insulation cotton or sound insulation felt.

[0034] like Figure 2As shown in the figure, the enclosing plate 131 includes a first arc plate 1311, a second arc plate 1312, a first flat plate 1313 and a second flat plate 1314. Among them, the second arc plate 1312 is arranged opposite to the first arc plate 1311. Both ends of the first flat plate 1313 are respectively connected to the first arc plate 1311 and the second arc plate 1312. The second flat plate 1314 is arranged opposite to the first flat plate 1313, and both ends of the second flat plate 1314 are respectively connected to the first arc plate 1311 and the second arc plate 1312; among them, the first arc plate 1311, the first flat plate 1313, the second arc plate 1312 and the second flat plate 1314 surround to form a receiving cavity, and the central axis of the first arc plate 1311 or the second arc plate 1312 is coaxially arranged with the central axis of the rotating shaft 14.

[0035] As Figure 1 , Figure 3 , Figure 4 and Figure 6 shown, the sound insulation device further includes a magnetic attraction assembly. The magnetic attraction assembly includes a first attraction structure and a second attraction structure 304. The first attraction structure is arranged on a receiving structure 301 for magnetically attracting the lower end of the first sound insulation structure 310 or is formed by at least part of the receiving structure 301, and the second attraction structure 304 is arranged on the first sound insulation structure 310 or is located inside the first sound insulation structure 310. Among them, one of the first attraction structure and the second attraction structure 304 is a first magnet, and the other of the first attraction structure and the second attraction structure 304 is a second magnet or is made of ferromagnetic metal. In this way, the above settings make the selection of the structures of the first attraction structure and the second attraction structure 304 more flexible on the one hand to meet different use requirements and working conditions, and also improve the processing flexibility of the staff; on the other hand, it ensures that the first sound insulation structure 310 can be magnetically attracted or separated from the receiving structure 301 to play a role in sound insulation and noise reduction and facilitate maintenance.

[0036] In this embodiment, the first attraction structure is formed by at least part of the receiving structure and is a first magnet, and the second attraction structure 304 is arranged on the first sound insulation structure 310 and is a second magnet. In this way, when the sound insulation device is in the initial state, the first magnet is magnetically attracted to the second attraction structure 304, effectively ensuring that low-frequency vibration can be fully transmitted into the first sound insulation structure 310, thereby effectively ensuring the low-frequency noise reduction effect. In case of strong wind weather, when the force of the wind on the first sound insulation structure 310 is greater than the magnetic attraction force between the first attraction structure and the second attraction structure 304, the first sound insulation structure 310 can be separated from the receiving structure 301, allowing the wind to pass through smoothly, which can not only ensure that the first sound insulation structure 310 will not be damaged, but also prevent safety problems in use due to excessive wind resistance.

[0037] Specifically, the second attraction structure 304 is a bar magnet, and the first sound insulation structure 310 is filled with a plurality of spherical damping particles, which can effectively enhance the surface contact force between the spherical damping particles, thereby enhancing the inelastic collision and friction effect between the spherical damping particles, and further enhancing the noise reduction effect.

[0038] It should be noted that the arrangement positions of the first suction structure and the second suction structure 304 are not limited thereto, and can be adjusted according to working conditions and usage requirements.

[0039] In other embodiments not shown in the accompanying drawings, the first attraction structure is arranged on a receiving structure for magnetically attracting the lower end of the sound insulation structure and is a first magnet, and the second attraction structure is located in the sound insulation structure and is made of ferromagnetic metal, so that when the sound insulation device is in the initial state, the first magnet and the second attraction structure are magnetically attracted, effectively ensuring that low-frequency vibrations can be fully transmitted to the sound insulation structure, thereby effectively ensuring the low-frequency noise reduction effect. If there is strong wind, when the force of the wind on the sound insulation structure is greater than the magnetic attraction force between the first attraction structure and the second attraction structure, the sound insulation structure can be separated from the receiving structure, so that the wind can pass smoothly, which can not only ensure that the sound insulation structure will not be damaged, but also prevent the use safety problems caused by excessive wind resistance.

[0040] Optionally, the first sound insulation structure 310 includes a sound insulation board 302, a sound insulation container 303 and a connecting assembly. The first end of the sound insulation board 302 is rotatably connected to a receiving structure 301. The sound insulation container 303 is movably connected to the second end of the sound insulation board 302, and the second suction structure 304 is arranged in the sound insulation container 303 or on the surface of the sound insulation container 303 away from the first end; the sound insulation container 303 is made of non-ferromagnetic material. The second end of the sound insulation board 302 is connected to the sound insulation container 303 through a connecting assembly, and the connecting assembly includes an elastic structure 5, which is connected to the sound insulation container 303 to apply an elastic force to the sound insulation container 303 to move toward one side of the sound insulation board 302. When the first sound insulation structure 310 is in the suction state, the elastic structure 5 is in a stretched state. In this way, the soundproof container 303 is filled with spherical damping particles, and the vibration mechanism of the vibration system is consumed through the inelastic collision and friction between the spherical damping particles to achieve the effect of low-frequency noise reduction, thereby ensuring that the sound insulation device can soundproof and reduce high-frequency noise and low-frequency noise. At the same time, when the soundproof container 303 is magnetically attracted to the first attraction structure, the elastic structure 5 is in a stretched state; when the soundproof container 303 is separated from the first attraction structure, the elastic structure 5 drives the soundproof container 303 to apply an elastic force moving toward one side of the soundproof board 302 to achieve rapid separation of the soundproof container 303 and the receiving structure 301. Figure 3 and Figure 4As shown, the spherical damping particles 305 are filled in the sound insulation container 303 and the sound insulation container 303 is made of non-ferromagnetic material, thereby reducing the magnetic adsorption force between the first attraction structure and the second attraction structure 304. Under the premise of ensuring that the sound insulation device can perform sound insulation and noise reduction, the first attraction structure and the second attraction structure 304 are easily separated under the action of wind, which can not only ensure that the first sound insulation structure 310 will not be damaged, but also prevent the use safety problem caused by excessive wind resistance.

[0041] In this embodiment, the second suction structure 304 is disposed in the sound insulation container 303, and the sound insulation container 303 is made of aluminum.

[0042] Specifically, when it is necessary to inspect the conveyor belt, the inspector can directly push the soundproof container 303 to separate the soundproof container 303 from the receiving structure 301 and avoid part of the installation opening. At this time, the inspector can enter through the installation opening and perform equipment inspection. At the same time, the sound insulation board 302 is used to isolate high-frequency noise, and low-frequency vibration can be fully transmitted to the soundproof container 303, thereby effectively ensuring the low-frequency noise reduction effect.

[0043] In this embodiment, the elastic structure 5 is a spring, and when the first sound insulation structure 310 is in the attracted state, the spring is in a stretched state. In this way, the above arrangement makes the structure of the elastic structure 5 simpler, easier to process and realize, and reduces the processing cost and difficulty of the elastic structure 5.

[0044] like Figures 2 to 4 As shown, the connection assembly also includes a connection body 4 and a connection rod 7. The connection body 4 has a first installation opening and a guide hole 6 that are interconnected. At least part of the soundproof container 303 extends into the first installation opening to surround at least part of the connection body 4 to form a mounting cavity, and the elastic structure 5 is arranged in the mounting cavity. The connection rod 7 is inserted into the guide hole 6 and the soundproof container 303 to drive the soundproof container 303 to move toward or away from the soundproof board 302 along the extension direction of the guide hole 6. In this way, the above arrangement ensures that the soundproof container 303 can perform telescopic movement relative to the connection body 4. On the one hand, it ensures that the soundproof container 303 can be magnetically attracted and separated from the first attraction structure, and ensures that the soundproof device can soundproof and reduce noise on the conveyor belt, and it is also convenient for the staff to maintain the tubular belt conveyor; on the other hand, it prevents the soundproof container 303 from rotating around the connection rod 7 and causing the soundproof container 303 and / or the receiving structure 301 to be damaged due to motion interference.

[0045] In this embodiment, there are two guiding holes 6 which are arranged oppositely. The connecting rod 7 extends into the two guiding holes 6, and the extending direction of each guiding hole 6 is consistent with the lifting direction of the sound insulation container 303. Wherein, one end of the connecting body 4 is welded to the sound insulation board 302, the other end of the connecting body 4 has a first mounting opening, and the guiding hole 6 is arranged at this end.

[0046] Optionally, there is one elastic structure 5; or, there are multiple elastic structures 5 which are all arranged in the mounting cavity. In this way, the above setting makes the selection of the number of the elastic structures 5 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0047] In this embodiment, the sound insulation board 302 is of a hollow structure, and a second sound insulation material 3021 is filled in the hollow structure. The second sound insulation material 3021 is sound insulation cotton or sound insulation felt; and / or, a third sound insulation material 8 is filled in the second mounting hole. The third sound insulation material 8 is sound insulation cotton or sound insulation felt. In this way, the above setting ensures that the sound insulation board 302 and / or the connecting component have a noise reduction and sound insulation effect, thereby reducing the noise generated during the operation of the conveyor belt and improving the user experience. At the same time, the above setting makes the selection of the structures of the second sound insulation material 3021 and the third sound insulation material 8 more diverse to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0048] Specifically, the sound insulation board 302 includes a plurality of plate bodies 3022 connected end to end. The plate bodies 3022 are first steel plates, and a plurality of first steel plates surround to form a hollow cavity. The second sound insulation material 3021 is arranged in the hollow cavity. The connecting body 4 is made by welding three second steel plates distributed in an n shape to each other, and the second steel plate located at the uppermost part is fixedly connected to the bottom end of the plate body 3022 by welding.

[0049] Optionally, there are multiple first sound insulation structures 310 on the same side, and the multiple first sound insulation structures 310 are arranged at intervals along the height direction and / or the length direction of the sound insulation device; there are multiple receiving structures 301 on the same side, and the multiple receiving structures 301 are arranged at intervals along the height direction of the sound insulation device. The multiple receiving structures 301 include at least one first sub-receiving structure 3011 and at least one second sub-receiving structure 3012. The first sub-receiving structure 3011 is arranged between two adjacent first sound insulation structures 310, and the second sub-receiving structure 3012 is arranged below the lowermost first sound insulation structure 310. In this way, the above arrangement increases the sound insulation area of the first sound insulation structure 310, thereby improving the sound insulation effect of the sound insulation device to prevent the noise generated during the operation of the conveyor belt from being transmitted to the residential area. At the same time, two adjacent first sound insulation structures 310 are connected by the first sub-receiving structure 3011, and the second sub-receiving structure 3012 is arranged below the lowermost first sound insulation structure 310 and magnetically attracts or separates from the second sub-receiving structure 3012.

[0050] In this embodiment, there are multiple groups of sound insulation structures on the same side, and the multiple groups of sound insulation structures are arranged at intervals along the conveying direction of the conveyor belt. Each group of sound insulation structures includes two first sound insulation structures 310, and the two first sound insulation structures 310 are arranged at intervals along the height direction of the sound insulation device. A first sub-receiving structure 3011 is arranged between the two first sound insulation structures 310, and the second sub-receiving structure 3012 is located below the lowermost first sound insulation structure 310.

[0051] It should be noted that each group of sound insulation structures includes three, or four, or five, or multiple first sound insulation structures 310.

[0052] As Figure 5 shown, the first sub-receiving structure 3011 includes a first plate segment 3011a, a second plate segment 3011b, and a third plate segment 3011c. The third plate segment 3011c is arranged opposite to the first plate segment 3011a, and the first plate segment 3011a is connected to the third plate segment 3011c through the second plate segment 3011b. The first plate segment 3011a, the second plate segment 3011b, and the third plate segment 3011c surround to form a second installation opening 3011d. In this way, the above arrangement makes the structure of the first sub-receiving structure 3011 simpler, easier to process and implement, and reduces the processing cost and processing difficulty of the first sub-receiving structure 3011.

[0053] In this embodiment, the first end of the sound insulation container 303 is movably connected to the connection body 4, the second end of the sound insulation container 303 is used for magnetic attraction with the receiving structure 301, and the cross-sectional area of the first end is smaller than that of the second end. In this way, the cross-sectional area of the sound insulation container 303 is larger than its upper cross-sectional area, and the bottom surface of the sound insulation container 303 is arranged in a flat shape so that the sound insulation container 303 fits better with the receiving structure 301. Under the action of the first magnetic attraction structure for magnetically adsorbing spherical damping particles, the bottom surface of the sound insulation container 303 is stressed and fits on the top side surface of the corresponding receiving structure 301.

[0054] Specifically, when the wind force is too large, the sound insulation container 303 swings along with the sound insulation board 302. During the swinging process, the spring is stretched, so that the spring forms a pulling force on the sound insulation container 303 to improve the smoothness when the sound insulation container 303 leaves the receiving structure 301. After the sound insulation container 303 leaves the receiving structure 301, the stretched spring resets, and the sound insulation container 303 retracts slightly, so that there is a gap between it and the receiving structure 301. In this way, when the wind blows by, there will be no interference between the sound insulation board 302 and the sound insulation container 303 during the reset process, effectively ensuring that the reset sound insulation container 303 can form sufficient contact with the receiving structure 301 again, and ensuring that the sound insulation device can reduce noise and isolate sound. Among them, during the manufacturing process, the upper part of the sound insulation container 303 filled with spherical damping particles can be welded to the spring in advance and the spring can be stretched. Then, the topmost second steel plate is welded to the top of the spring, and the other two second steel plates are welded on both sides of this second steel plate. Finally, the topmost second steel plate is welded to the bottom of the first steel plate of the sound insulation board 302, thereby improving the convenience of the entire installation and construction.

[0055] In this embodiment, the receiving structure 301 is the first magnetic attraction structure, and the second magnetic attraction structure 304 is arranged on the inner bottom surface of the sound insulation container 303. Among them, the bottom surface of the sound insulation container 303 includes a flat surface and an arc surface, the arc surface surrounds the flat surface, and the first magnetic attraction structure is used for fitting with the flat surface. In this way, during the movement of the sound insulation container 303 relative to the receiving structure 301, the above setting of the arc surface can prevent structural interference between the sound insulation container 303 and the receiving structure 301 and damage the sound insulation container 303, extending the service life of the sound insulation device.

[0056] Such as Figure 1As shown in the figure, the sound insulation device further includes a limiting rod 12. The limiting rod 12 is located at the installation opening and inside the first sound insulation structure 310 for limiting and blocking the first sound insulation structure 310. Specifically, limiting rods 12 for limiting the unfolding angle of the sound insulation board 302 are fixedly connected between the supporting members inside the upper receiving structure 301 among two adjacent receiving structures 301. The unfolding angle of the sound insulation board 302 is restricted by the limiting rod 12 to prevent the sound insulation board 302 from colliding with the pipe belt conveyor after being blown open by the wind, thereby effectively further improving the practical effect.

[0057] As Figure 1 shown in the figure, a fixing block 11 is fixedly connected downward at a position corresponding to the upper end of the first sound insulation structure 310 on the receiving structure 301. Both ends of the pivot shaft of the first sound insulation structure 310 extend to the outside of the plate body 3022 and are rotatably installed on the corresponding fixing blocks 11.

[0058] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0059] The sound insulation device includes a machine base and a sound insulation component. The machine base includes a top plate, a bottom plate and a support plate. The top plate is connected to the bottom plate through the support plate. The support plate has a first installation hole for installing the conveyor belt of the tubular belt conveyor. The top plate, the bottom plate and the support plate surround to form an installation opening, and the installation opening is located on both sides of the conveyor belt. The sound insulation component is arranged at the installation opening. The sound insulation component includes a first sound insulation structure, a second sound insulation structure and at least two receiving structures. The receiving structures are arranged on the support plate, and the upper end of the sound insulation structure is rotatably connected to one of the receiving structures. The first sound insulation structure has a second installation hole, and the second sound insulation structure is movably arranged in the second installation hole to block or avoid the second installation hole. In this way, the lower end of the first sound insulation structure has a suction state of magnetically attracting to another receiving structure and a maintenance state of separating from the receiving structure. In the initial state, the first sound insulation structure is in the suction state, playing a role in sound insulation and noise reduction for the conveyor belt. When the staff needs to maintain the conveyor belt, the first sound insulation structure is operated to switch the first sound insulation structure from the suction state to the maintenance state. At this time, the staff can maintain the conveyor belt through the installation opening. Since the first sound insulation structure is magnetically attracted to the receiving structure and the second sound insulation structure is movably arranged on the first sound insulation structure, in case of strong wind weather, the first sound insulation structure can be separated from the receiving structure under the action of wind force, reducing the resistance received by the sound insulation structure to prevent the overall overturning of the conveyor, and the second sound insulation structure can rotate relative to the first sound insulation structure under the action of wind force to avoid the second installation hole, thus solving the problem in the prior art that the sound insulation device affects the normal maintenance of the conveyor by the staff and even poses a safety hazard, facilitating the staff to maintain the conveyor and reducing the safety hazard brought by the sound insulation device.
