Description

Technical Field

[0001] The utility model relates to the field of equipment vibration isolation devices, in particular to a polyethylene rubber vibration isolation pad. Background Art

[0002] The operation of equipment, especially large equipment, generates vibration and noise, which puts a strain on the supporting foundation and platform. The noise, in turn, adversely affects users and the surrounding public. Environmental protection requirements often include decibel limits for noise emissions from equipment. To reduce vibration and noise, a vibration isolation structure must be installed at the bottom of the equipment, typically using a coil spring isolator. While coil spring isolators offer good cushioning properties, they have poor damping properties and a relatively high natural frequency. When the equipment resonates with the spring, this increases the equipment's amplitude. Furthermore, coil spring isolators can only offset vertical vibrations and are ineffective against horizontal vibrations. Utility Model Content

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the utility model provides a polyethylene rubber vibration isolation pad, which solves the problem that the coil spring vibration isolator has poor damping and cannot offset horizontal vibration when used as the vibration isolation structure of the equipment.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0018] In the description of the embodiments of the present invention, it should be noted that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0019] See also Figure 1The present invention provides a technical solution: a polyethylene rubber vibration isolation pad comprising a plate 1 made of chlorinated polyethylene (CPE) lined with a steel plate 2. It should be noted that CPE is a high-molecular-weight polymer produced by the chlorination reaction of polyethylene and can also be considered a terpolymer of ethylene, vinyl chloride, and 1,2-dichloroethylene. Based on its properties and uses, it can be divided into two categories: resins (CPE) and elastomers (CM). The "Application Research of New Chlorinated Polyethylene Rubbers" in the 2001 issue of "Rubber Industry" (No. 6) describes the application of new polyethylene rubbers. Resin-type CPE and elastomer-type CPE are suitable materials for the plate 1 of this invention. CPE has excellent damping properties, chemical corrosion resistance, flame retardancy, and mechanical damage resistance, particularly in high-temperature and chemically corrosive environments. Lining the plate 1 with a steel plate 2 enhances its rigidity, further lowers its natural frequency, and reduces the occurrence of resonance. The plate 1 can offset both vertical and horizontal vibrations.

[0020] See also Figure 1 In this embodiment, the steel plate 2 is arranged parallel to the plate surface of the plate body 1, and two steel plates 2 are arranged, and the two steel plates 2 are respectively arranged near the upper and lower end surfaces.

[0021] See also Figure 1 In this embodiment, an anti-skid structure 3 is provided on the upper end of the plate body 1. It should be noted that the significance of providing the anti-skid structure 3 is that, since the vibration isolation pad often needs to be cast together with the foundation, when its anti-skid performance is poor, due to the long-term expansion and contraction of the vibration isolation pad, it may be deformed and offset to a certain extent relative to the foundation. The provision of the anti-skid structure 3 can better consolidate the vibration isolation pad with the foundation, avoiding or reducing the occurrence of the above-mentioned situation.

[0022] See also Figure 1 In this embodiment, the anti-slip structure 3 is configured as protrusions evenly arranged on the upper end surface of the plate body 1.

[0023] The working principle and usage process of this utility model: When in use, the equipment is fixed together with the vibration isolation pad, and the vibration isolation pad is cast together with the foundation. Since the upper end surface of the vibration isolation pad is provided with uniform protrusions, it can be better consolidated with the cement mortar, avoiding or reducing the relative movement between the vibration isolation pad and the foundation.

[0024] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
