Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection for noise control, and specifically, to a vibration damping and sound insulation device. Background Art

[0002] With the economic development and the improvement of environmental protection requirements, civilized production has become an important part of the enterprise's environmental protection. As a kind of pollution, noise not only has a serious impact on the physical and mental health of workers in the factory, but also interferes with the surrounding natural and human environments. Under the background of the country's strong promotion of environmental protection, in order to actively respond to the country's call, special equipment for noise control is particularly important. Belt conveyors are widely used in the material conveying link as large-flow conveying equipment. During the high-speed rotation of the rollers, mechanical and vibration noises are generated due to the friction with the belt, and are transmitted to the corridor through the legs of the belt conveyor, affecting the surrounding sound environment. Enclosing the belt conveyor and the corridor surface has a high investment cost, and it will affect the safety of the original corridor structure due to the large additional load.

[0003] Therefore, providing a vibration damping and sound insulation device to take targeted vibration damping measures for strongly vibrating conveying equipment, effectively reducing the vibration frequency of the equipment, reducing the transmission of the equipment vibration noise through the base, and effectively controlling the impact of the equipment vibration noise on the external sound environment will be of great significance for noise control. Summary of the Invention

[0004] Based on the above situation, the present invention aims to find a technical product with good vibration damping effect, not affecting the normal operation of the equipment, low investment cost and convenient implementation. The present invention provides a vibration damping and sound insulation device, which respectively uses rubber blocks as the vibration damping main body, and internally embeds connecting and fixing parts to be connected with a base composed of multiple horizontally arranged steel belts intersecting each other, so as to absorb and suppress the vibration noise of the material conveying equipment from being transmitted from the legs to the corridor surface, reduce the diffusion impact of the vibration noise on the surrounding environment, and at the same time ensure the stable and safe operation of the conveying equipment, and achieve the ultimate goal of civilized and environmental protection production.

[0005] The present invention provides a vibration damping and sound insulation device, including a fixed base, and the fixed base at least includes multiple horizontally arranged steel belts intersecting each other; rubber blocks arranged above the steel belts, and multiple longitudinal connecting and fixing parts are embedded in the rubber blocks, one end of the connecting and fixing parts is connected with the steel belts, and the other end is connected with the legs or the bearing platform of the material conveying equipment.

[0006] Preferably, the connecting and fixing parts are longitudinal steel belts.

[0007] Preferably, the lower end of the longitudinal steel belt is T-shaped.

[0008] Preferably, rubber is coated or filled between the T-shaped end of the longitudinal steel belt and the rubber block.

[0009] Preferably, the fixed base further includes a plurality of bolts. Through holes are provided at both ends of the horizontal steel belt, and both ends of the horizontal steel belt are connected to the corridor platform through the bolts passing through the through holes.

[0010] Preferably, a rubber gasket is provided on the contact surface between the bolt and the corridor platform.

[0011] Preferably, the connecting and fixing member is connected to the leg or the bearing platform of the material conveying equipment through bolts.

[0012] In the ramp conveying equipment, there are vibrations in the horizontal and vertical directions. This set of vibration damping devices uses high-performance vibration damping materials and a unique structural design. Relying on the rubber block as the main body, it bears the vibrating equipment and weakens the vibration frequency of the vibration source. Connecting and fixing members are embedded inside the rubber block and connected to the legs and bearing platforms of the equipment (such as a belt conveyor) respectively. The vibration of the equipment passes through the rubber block, and the forces in the vertical direction and along the ramp direction are respectively transmitted through the rubber block, so that the vibration frequency is weakened. At the same time, in the present invention, a plurality of horizontally arranged steel belts intersecting each other form a placement and fixing base for the rubber block. Since the plurality of horizontally arranged steel belts intersecting each other are non-rigid bodies, the vibration transmitted from the rubber block is further reduced under the action of the horizontal steel belts, thereby weakening the vibration frequency of the vibration source, reducing the vibration noise, absorbing and suppressing the noise of the vibration of equipment such as a belt conveyor from being transmitted from the legs to the corridor surface, reducing the diffusion influence of the vibration noise on the surrounding environment, and at the same time ensuring the stable and safe operation of the conveying equipment, achieving the purpose of civilized and environmental protection production.

[0023] As Figure 1 , Figure 2 shown, the present invention provides a vibration damping and sound insulation device, including a fixed base, the fixed base at least includes a plurality of horizontally arranged steel belts 1 which are cross - arranged; a rubber block 2 arranged above the horizontal steel belt 1, and a plurality of longitudinal connecting and fixing members are embedded in the rubber block 2. One end of the connecting and fixing member is connected to the horizontal steel belt 1, and the other end is connected to the leg or the bearing platform of the material conveying equipment.

[0024] In the ramp conveying equipment, there are vibrations in the horizontal and vertical directions. This set of vibration damping devices adopts high - performance vibration damping materials and unique structural designs, relying on the rubber block as the main body to carry the vibrating equipment and weaken the vibration frequency of the vibration source. Connecting and fixing members are embedded inside the rubber block and connected to the legs and bearing platforms of the equipment (such as belt conveyors) respectively. The vibrations of the equipment pass through the rubber block, and the forces in the vertical direction and along the ramp direction pass through the rubber block respectively, so that the vibration frequency is weakened. At the same time, in the present invention, a plurality of horizontally arranged and cross - arranged steel belts form the placement and fixing base of the rubber block 2. Since the plurality of horizontally arranged and cross - arranged steel belts are non - rigid bodies, the vibrations transmitted from the rubber block are further slowed down under the action of the horizontal steel belts, thereby weakening the vibration frequency of the vibration source, reducing the vibration noise, absorbing and suppressing the noise of the vibration of equipment such as belt conveyors from being transmitted from the legs to the corridor surface, reducing the diffusion impact of the vibration noise on the surrounding environment, and at the same time ensuring the stable and safe operation of the conveying equipment, achieving the purpose of civilized and environmental protection production.

[0027] In a preferred embodiment of the present invention, the lower end of the longitudinal steel belt 4 is T - shaped. Thereby increasing the contact area between the longitudinal steel belt 4 and the rubber block 2, and further slowing down the vibration transmitted from the leg or the bearing platform.

[0028] In a preferred embodiment of the present invention, rubber is coated or filled between the T-shaped ends of the longitudinal steel belts 4 and the rubber blocks 2, further reducing the vibration transmitted from the legs or the bearing platform.

[0029] In a preferred embodiment of the present invention, the fixed base further includes a plurality of bolts 5. Through holes 3 are provided at both ends of the horizontal steel belt 1, and both ends of the horizontal steel belt 1 are connected to the corridor platform by bolts 5 passing through the through holes 3. This makes the installation of the device simple and the transformation cost low.
