Description

Technical Field

[0001] The present invention relates to a mounting seat, and in particular to an elastically wrapped vibration reduction device and a vibration reduction base structure capable of achieving vibration reduction. Background Art

[0002] The base vibration reduction structure is widely used in power components such as engines, electric motors, and ship engine rooms. Because the parts are prone to vibration during operation, the vibration is transmitted to the platform and affects the operating stability of other equipment on the platform.

[0003] In order to solve the problem of vibration reduction, technicians in this field have developed a variety of vibration reduction structures, such as elastic pad vibration reduction, spring vibration reduction, and resonance vibration reduction. Among them, elastic pad vibration reduction has a simple structure and obvious vibration reduction effect. It is mainly used for vibration reduction of fixed power with small vibration amplitude. Spring vibration reduction is mainly used for mechanical vibration reduction with large vibration amplitude, such as vibrating screens and vehicles. Resonance vibration reduction is mainly used for high-frequency vibration reduction, such as coordinated vibration dampers on rails.

[0004] Since the vibration source of the machine parts generates noise during the vibration process, the cabin needs to be soundproofed, which requires the use of a large amount of sound insulation materials and fails to protect the vibration source itself. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a multi-stage vibration-damping base structure.

[0006] The present invention is achieved through the following technical solution: an elastically wrapped vibration damping device, including an enclosure, a base body is arranged in the enclosure, a vibration damping cavity is formed between the base body and the enclosure, an elastic vibration damping body is arranged in the vibration damping cavity, and the elastic vibration damping body is wrapped around the lower end or outer surface of the base body.

[0007] Furthermore, the enclosure and the base are both provided with anchor columns for inserting elastic vibration damping bodies.

[0008] A vibration-damping base structure includes an elastically wrapped vibration-damping device, wherein an elastic support device for connecting to a mounting platform is provided outside the wrapping body, and the elastic support device includes a connecting end connected to the wrapping body and a mounting end connected to the mounting platform, and an elastic member is provided between the connecting end and the mounting end.

[0009] The beneficial effects of the present invention are: an elastically wrapped vibration damping device includes an enclosure, a base body is arranged in the enclosure, a vibration damping cavity is formed between the base body and the enclosure, an elastic vibration damping body is arranged in the vibration damping cavity, and the elastic vibration damping body is wrapped around the lower end or outer surface of the base body. The elastic vibration damping body can have a larger contact area with the base body and can better receive vibration. The vibration is attenuated during the transmission process in the elastic vibration damping body, reducing noise, and the vibration is dispersed and will not be concentrated when transmitted to the enclosure, thereby avoiding local overload of the enclosure and improving service life and vibration damping stability.

DETAILED DESCRIPTION

[0018] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1-2 As shown, a vibration-damping base structure includes a base body. In this embodiment, the base body is a groove 2, and a clip hook 13 inclined toward the bottom surface of the groove is integrally formed at the opening of the groove, which has a better connection and fastening effect with the T-bolt 3, and the overall strength and bearing capacity of the groove are better. The side surface of the opening of the groove 2 is processed with anti-slip teeth 11, and the end face shape of the tooth shape of the anti-slip tooth is a triangle or other tooth shape, among which the triangle is the optimal solution, making the bite more secure. The anti-slip teeth are processed on one or both sides of the side of the groove opening, wherein processing on both sides is the best solution. A T-bolt is installed in the groove to connect it with other accessories. The bolt head of the T-bolt and the connection position at the opening are processed with a groove matching the clip hook. A gasket 4 is installed on the groove. The gasket is located on the top surface of the open end of the groove. A boss 12 matching the groove opening is processed on the gasket. The boss is stuck in the opening. The side of the boss is processed with anti-slip teeth 2 matching the anti-slip teeth 1. A through hole matching the T-bolt is processed on the gasket. The gasket passes through the stud part of the T-bolt through the through hole. The gasket is connected to the groove through the anti-slip teeth 2 and the anti-slip teeth 1. The gasket can prevent the T-bolt from slipping and improving the locking effect of the groove. After the gasket is installed, it is tightened by a anti-loosening nut to prevent loosening during vibration.

[0022] A multi-stage vibration damping device is connected, and the multi-stage vibration damping device includes an elastically wrapped vibration damping device connected to the base body. The elastically wrapped vibration damping device includes an enclosure 1, and a vibration damping cavity 10 is formed between the enclosure and the lower end of the base body. The vibration damping cavity is filled with an elastic vibration damping body, and the elastic vibration damping body is connected to the enclosure and the base body. Specifically, the elastic vibration damping body is rubber, and the J2049 two-component polyurethane adhesive of Shandong Dongda Chemical Soil Group Co., Ltd. is specifically selected.

[0023] Anchor columns for inserting elastic vibration dampers are fixed on the inclusion body and the base. In this embodiment, the anchor columns are weld nails 6, and the cylindrical heads of the weld nails face the middle position of the vibration damping cavity. Through the weld nails, the groove, the inclusion body and the elastic vibration damper can be stably connected.

[0024] The elastic wrapped vibration damping device is externally connected to an elastic support device for installation on the mounting platform. The elastic support device includes a connecting end 7 connected to the wrapping body and a mounting end 9 connected to the mounting platform. An elastic member 8 is installed between the connecting end and the mounting end. Specifically, the elastic member is an arc-shaped steel plate, the connecting end is a connecting plate, and the mounting end is a mounting plate. The two wings of the arc-shaped steel plate are respectively integrally formed at the connecting end and the mounting end. The elastic members are evenly spaced on both sides of the wrapping body, which is convenient for bolt installation and suitable for fixing to the frame.

[0025] The elastic vibration damper can have a larger contact area with the base body, and can better absorb vibration. The vibration is attenuated during the transmission in the elastic vibration damper, reducing noise, and the vibration is dispersed. It will not be concentrated when transmitted to the enclosing body, avoiding local overload of the enclosing body, improving service life and vibration reduction stability. Through the interaction of anchor columns, rubber blocking and absorption-type vibration reduction, this application can use rubber with lower hardness. The end of the base body and the end of the enclosing body are supported by support blocks to avoid the base body directly pressing on the elastic vibration damper, and three-dimensional vibration reduction to improve the vibration reduction effect.

[0026] It is worth noting that the base body can also use installation components such as slide rails and guide rails, and the elastic shock absorber can also be wrapped around the overall outer surface of the base body to wrap the base body in a larger area and improve the vibration reduction effect.

[0027] Example 2

[0028] like Figure 3 As shown, a vibration-damping base structure is different from Example 1 in that the arc-shaped steel plate extends to both ends of the enveloping body, the connecting ends 7 are spaced connecting plates, and welding openings 14 are formed between two adjacent connecting plates, thereby increasing the welding area and improving the connection stability. The lower wing end of the arc-shaped steel plate forms a mounting end, which is then welded and fixed to the platform.

[0029] Example 3

[0030] like Figure 4 As shown, a vibration-damping base structure is different from Example 2 in that the lower end of the elastic member is fixed to the base plate, and both sides of the base plate extend to the outside of the elastic member to form mounting ends.

[0031] Example 4

[0032] like Figure 5-6As shown, a vibration-damping base structure is different from Examples 1-3 in that a filling ball 15 is filled in the vibration-damping cavity. The filling ball is a rubber ball, and the rubber ball is made of vulcanized rubber. A steel ball 20 is placed in the rubber ball with a volume of 2 / 3. During the vibration process, the steel ball jumps irregularly in the rubber ball, and multiple steel balls interfere with each other, thereby weakening the vibration. After adding the filling ball, rubber is injected to fill the gap and form connections between the rubber balls. Since the air content in the rubber ball is reduced, the expansion caused by thermal expansion is reduced, and the surface of the steel ball is oxidized at high temperature, absorbing oxygen, further reducing thermal expansion.

[0033] Example 5

[0034] like Figure 7 As shown, a vibration-damping base structure is different from Examples 1-4 in that a prefabricated support block 16 is filled in the vibration-damping cavity. The prefabricated support block is a rubber block. An opening 18 that matches the welding nail is prefabricated on the rubber block. A horizontal support plate 17 is provided at the lower end of the prefabricated support block. The support plate is squeezed between the groove and the inclusion body. During the installation process, the prefabricated support block is placed first, and then the groove is placed. A gap is reserved between two adjacent prefabricated support blocks to form a glue injection port 19. Glue is injected into the vibration-damping cavity through the glue injection port. The introduction of the prefabricated support block can reduce the amount of glue injected, thereby shortening the curing time. At the same time, it can reduce the gap caused by curing and improve the connection stability between the elastic vibration damping body and the groove and the inclusion body.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
