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.

Detailed implementation manners

[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" are generally in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for ease of understanding and description, "left, right" are generally left and right as shown in the drawings; "inside, outside" refer to inside and outside the contour of each component itself, but the above orientation terms do not limit the present invention.

[0030] 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.

[0031] 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 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 sound insulation structure 310 and at least two receiving structures 301. The receiving structure 301 is arranged on the support plate 103. The upper end of the sound insulation structure 310 is rotatably connected to one receiving structure 301. The lower end of the 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.

[0032] 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 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 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, and the sound insulation component 3 includes a sound insulation structure 310 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 310 is rotatably connected to one of the receiving structures 301. In this way, the lower end of the 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. In the initial state, the 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 sound insulation structure 310 is operated to switch the 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 sound insulation structure 310 is magnetically attracted to the receiving structure 301, if there is strong wind, the sound insulation structure 310 can be separated from the receiving structure 301 under the action of wind, reducing the resistance of the sound insulation structure 310 to prevent the conveyor from overturning as a whole, 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 safety hazards, making it convenient for the staff to maintain the conveyor and reducing the safety hazards caused by the sound insulation device.

[0033] In this embodiment, the mounting hole 2 is hexagonal.

[0034] likeFigure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the sound insulation device also includes a magnetic attraction component. The magnetic attraction component includes a first attraction structure 304 and a second attraction structure 306. The first attraction structure 304 is arranged on a receiving structure 301 for magnetically attracting the lower end of the sound insulation structure 310 or is formed by at least part of the receiving structure 301, and the second attraction structure 306 is arranged on the sound insulation structure 310 or is located in the sound insulation structure 310. Among them, one of the first attraction structure 304 and the second attraction structure 306 is a first magnet, and the other of the first attraction structure 304 and the second attraction structure 306 is a second magnet or is made of ferromagnetic metal. In this way, the above-mentioned setting makes the structural selection of the first attraction structure 304 and the second attraction structure 306 more flexible to meet different use requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, it ensures that the 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.

[0035] In this embodiment, the first attraction structure 304 is arranged on the receiving structure 301 for magnetically attracting the lower end of the sound insulation structure 310 and is a first magnet, and the second attraction structure 306 is located in the sound insulation structure 310 and is made of ferromagnetic metal. In this way, when the sound insulation device is in the initial state, the first magnet and the second attraction structure 306 are magnetically attracted, effectively ensuring that the low-frequency vibration can be fully transmitted to the sound insulation structure 310, thereby effectively ensuring the low-frequency noise reduction effect. If there is strong wind weather, when the force of the wind on the sound insulation structure 310 is greater than the magnetic attraction force between the first attraction structure 304 and the second attraction structure 306, the sound insulation structure 310 can be separated from the receiving structure 301, so that the wind can pass smoothly, which can not only ensure that the sound insulation structure 310 will not be damaged, but also prevent the use safety problem caused by excessive wind resistance.

[0036] Specifically, the second attraction structure 306 is a plurality of spherical damping particles, and the plurality of spherical damping particles are filled in the sound insulation structure 310, which can effectively improve the surface contact force between the spherical damping particles, thereby improving the inelastic collision and friction effect between the spherical damping particles, so as to further improve the noise reduction effect. The first attraction structure 304 is a bar magnet, which generates a magnetic adsorption force on the spherical damping particles in the corresponding sound insulation structure 310 through the bar magnet.

[0037] It should be noted that the arrangement positions of the first suction structure 304 and the second suction structure 306 are not limited thereto, and can be adjusted according to working conditions and usage requirements.

[0038] In other embodiments not shown in the drawings, the first attracting structure is formed by at least part of the receiving structure and is a first magnet, and the second attracting structure is disposed on the sound insulation structure 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 attracting structure, effectively ensuring that low-frequency vibrations can be fully transmitted into the sound insulation structure, thereby effectively ensuring the low-frequency noise reduction effect. In the event of strong winds, when the force of the wind on the sound insulation structure is greater than the magnetic attraction force between the first attracting structure and the second attracting structure, the sound insulation structure can be separated from the receiving structure, allowing the wind to pass through smoothly. This can not only ensure that the sound insulation structure is not damaged, but also prevent safety problems during use due to excessive wind resistance.

[0039] In other embodiments not shown in the drawings, the first sub-receiving structure 301 is the first attracting structure 304, and the second attracting structure 306 is disposed on the inner bottom surface of the sound insulation container 303.

[0040] Optionally, the sound insulation structure 310 includes a sound insulation board 302 and a sound insulation container 303. 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 attracting structure 306 is disposed inside the sound insulation container 303 or on the surface of the sound insulation container 303 away from the first end. Among them, the sound insulation container 303 is made of a non-ferromagnetic material. In this way, spherical damping particles are filled in the sound insulation container 303, and through the inelastic collision and friction between the spherical damping particles, the vibration energy of the vibration system is consumed to achieve the effect of low-frequency noise reduction, thereby ensuring that the sound insulation device can perform sound insulation and noise reduction processing on high-frequency and low-frequency noises.

[0041] As Figure 3 and Figure 4 shown, the spherical damping particles are filled in the sound insulation container 303 and the sound insulation container 303 is made of a non-ferromagnetic material, thereby reducing the magnetic adsorption force between the first attracting structure 304 and the second attracting structure 306. On the premise of ensuring that the sound insulation device can perform sound insulation and noise reduction, it is convenient for the first attracting structure 304 and the second attracting structure 306 to separate under the action of wind force. This can not only ensure that the sound insulation structure 310 is not damaged, but also prevent safety problems during use due to excessive wind resistance.

[0042] In this embodiment, the sound insulation container 303 is made of aluminum.

[0043] 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.

[0044] like Figures 2 to 4 As shown, the sound insulation structure 310 also includes a connection component. The second end of the sound insulation board 302 is connected to the sound insulation container 303 through the connection component, and the connection component 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. In this way, when the sound insulation container 303 is magnetically attracted to the first attraction structure 304, the elastic structure 5 is in a stretched state; when the sound insulation container 303 is separated from the first attraction structure 304, the elastic structure 5 drives the sound insulation container 303 to apply an elastic force to move toward one side of the sound insulation board 302, so as to achieve rapid separation of the sound insulation container 303 and the receiving structure 301.

[0045] In this embodiment, the elastic structure 5 is a spring, and when the 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.

[0046] 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 304, 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.

[0047] 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. 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.

[0048] 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.

[0049] In this embodiment, the sound insulation board 302 is of a hollow structure, and a first sound insulation material 3021 is filled in the hollow structure. The first sound insulation material 3021 is sound insulation cotton or sound insulation felt; and / or, a second sound insulation material 8 is filled in the mounting hole 2. The second 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 first sound insulation material 3021 and the second sound insulation material 8 more diverse to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0050] 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 first 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. The second steel plate located at the uppermost part is fixedly connected to the bottom end of the first steel plate by welding.

[0051] Optionally, there are multiple sound insulation structures 310 on the same side, and the multiple 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 sound insulation structures 310, and the second sub-receiving structure 3012 is arranged below the lowermost sound insulation structure 310. In this way, the above setting increases the sound insulation area of the sound insulation structures 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 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 sound insulation structure 310 and magnetically attracts or separates from the second sub-receiving structure 3012.

[0052] In this embodiment, there are multiple groups of sound insulation structures 310 on the same side. The multiple groups of sound insulation structures 310 are arranged at intervals along the conveying direction of the conveyor belt. Each group of sound insulation structures 310 includes two sound insulation structures 310. The two sound insulation structures 310 are arranged at intervals along the height direction of the sound insulation device. A first sub-bearing structure 3011 is arranged between the two sound insulation structures 310, and the second sub-bearing structure 3012 is located below the lowermost sound insulation structure 310.

[0053] It should be noted that each group of sound insulation structures 310 includes three, or four, or five, or more sound insulation structures 310.

[0054] As Figure 5 shown, the first sub-bearing structure 3011 includes a first plate section 3011a, a second plate section 3011b and a third plate section 3011c. The third plate section 3011c is arranged opposite to the first plate section 3011a. The first plate section 3011a is connected to the third plate section 3011c through the second plate section 3011b. The first plate section 3011a, the second plate section 3011b and the third plate section 3011c surround to form a second installation opening 3011d. The first suction structure 304 is arranged on the first plate section 3011a and is located within the second installation opening 3011d. Among them, the second suction structure 306 is arranged within the sound insulation container 303. In this way, the above arrangement makes the structure of the first sub-bearing structure 3011 simpler, easier to process and implement, and reduces the processing cost and difficulty of the first sub-bearing structure 3011.

[0055] Optionally, the first plate section 3011a has bolt holes, and the first suction structure 304 is a magnet with through holes. In this way, the staff first passes the bolt 10 through the through holes of the first suction structure 304, and then screws the bolt 10 into the bolt holes, so as to arrange the first suction structure 304 on the first plate section 3011a.

[0056] 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 suction with the bearing 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 planar shape, so that the sound insulation container 303 can better fit with the bearing structure 301. Under the action of the magnetic adsorption of the first suction structure 304 on the spherical damping particles, the bottom surface of the sound insulation container 303 is stressed and fits on the top side surface of the corresponding bearing structure 301.

[0057] 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 of the sound insulation container 303 when leaving 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 and the receiving structure 301, effectively ensuring that the reset sound insulation container 303 can come into full 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, thus improving the convenience of the entire installation and construction.

[0058] As Figure 1 shown, limiting rods 12 for limiting the unfolding angle of the sound insulation board 302 are fixedly connected between the support members on the inner sides of the upper receiving structures 301 among two adjacent receiving structures 301. The unfolding angle of the sound insulation board 302 is limited by the limiting rods 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.

[0059] As Figure 1 shown, fixing blocks 11 are fixedly connected downward at positions of the receiving structure 301 corresponding to the rotating shafts 3023. Both ends of the rotating shafts 3023 extend to the outside of the plate body 3022 and are rotatably installed on the corresponding fixing blocks 11.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] 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 mounting hole for mounting the conveyor belt of the tubular belt conveyor. The top plate, the bottom plate and the support plate surround to form a mounting port, and the mounting port is located on both sides of the conveyor belt. The sound insulation component is arranged at the mounting port. The sound insulation component includes a sound insulation structure and at least two receiving structures. The receiving structure is arranged on the support plate, and the upper end of the sound insulation structure is rotatably connected to one receiving structure. In this way, the lower end of the sound insulation structure has an attraction state of magnetic attraction with another receiving structure and a maintenance state separated from the receiving structure. In the initial state, the sound insulation structure 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 sound insulation structure is operated to switch the sound insulation structure from the attraction state to the maintenance state. At this time, the staff can maintain the conveyor belt through the mounting port. Since the sound insulation structure and the supporting structure are magnetically attracted, if there is strong wind, the sound insulation structure can be separated from the supporting structure under the action of wind, thereby reducing the resistance to the sound insulation structure to prevent the conveyor from overturning as a whole, 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 easier for the staff to maintain the conveyor and reducing the safety hazards caused by the sound insulation device.
