Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foundation vibration isolation, in particular to a foundation vibration isolation structure for fully automatic testing equipment of a coal robot entering a factory. Background Art
[0002] The fully automated testing equipment for coal entering the plant in a thermal power plant is a precision instrument and equipment, which has very high requirements for measurement and detection accuracy. The equipment contains a high-precision analytical balance, so the vibration limit of the equipment foundation is very high. According to the requirements of the "Standard for Permissible Vibration of Construction Engineering" (GB50868-2013), the peak value of the permissible vibration displacement of the analytical balance in the time domain is 4.8μm. The foundations of the fully automated testing equipment for coal entering the plant used in the current project can be divided into two categories, one is the traditional monolithic large-block reinforced concrete foundation, and the other is the monolithic large-block reinforced concrete foundation with vibration reduction grooves set around it to separate it from the surrounding vibration sources.
[0003] The foundation of the fully automatic inspection equipment for the coal robot entering the factory adopts a traditional integral large-block reinforced concrete foundation. In order to meet the requirements of the allowable vibration displacement peak, the method of increasing the deadweight and rigidity of the equipment foundation is generally adopted. Therefore, the foundation thickness is large and the reinforced concrete foundation volume is large, which is not economical; and in order to prevent the vibration of the surrounding environment from being directly transmitted to the equipment foundation through the floor, a vibration-damping ditch is usually set around the foundation. Although the vibration-damping ditch can block the vibration source, the vibration of the vibration source will still be transmitted to the equipment foundation through the foundation soil at the bottom of the vibration-damping ditch, thereby affecting the measurement and detection accuracy of the equipment. Utility Model Content
[0004] The purpose of the utility model is to address the defects of the prior art and provide a vibration isolation structure for the foundation of a fully automatic inspection equipment for a coal robot entering the factory, which can effectively reduce the impact of vibration in the surrounding environment on the foundation of the equipment, so that the foundation of the equipment can have better dynamic characteristics and more easily meet the allowable vibration displacement peak requirements of the equipment foundation within the time domain.
[0005] In order to solve the above technical problems, the utility model provides a foundation vibration isolation structure for a fully automatic inspection equipment of a coal robot entering the factory, comprising an equipment foundation and a vibration reduction ditch arranged on a foundation, wherein the vibration reduction ditch is arranged along the periphery of the equipment foundation, and the equipment foundation comprises a reinforced concrete foundation and a medium-coarse sand cushion layer, wherein the reinforced concrete foundation is arranged on the medium-coarse sand cushion layer, and the medium-coarse sand cushion layer is used to absorb vibrations from the foundation.
[0006] The utility model arranges a medium-coarse sand cushion layer under the reinforced concrete foundation. On the one hand, the medium-coarse sand cushion layer can absorb vibrations from the foundation and prevent the vibrations from being directly transmitted to equipment through the reinforced concrete foundation. On the other hand, the medium-coarse sand cushion can meet the requirements of bearing capacity and settlement deformation, reduce the volume of the reinforced concrete foundation, and improve economy.
[0007] Furthermore, a flexible isolation plate is arranged between the reinforced concrete foundation and the medium-coarse sand cushion layer.
[0008] The utility model further absorbs the vibration from the foundation by arranging a flexible isolation plate between the reinforced concrete foundation and the medium-coarse sand cushion layer.
[0009] Furthermore, a flexible isolation plate is arranged between the reinforced concrete foundation and the vibration reduction ditch.
[0010] The utility model arranges a flexible isolation plate between the reinforced concrete foundation and the vibration reduction groove, and the flexible isolation plate can absorb the vibration transmitted from the vibration reduction groove to the reinforced concrete foundation, thereby further reducing the vibration of the equipment.
[0011] Furthermore, a flexible isolation plate is arranged between the vibration reduction groove and the hardened floor around the vibration reduction groove.
[0012] The utility model arranges a flexible isolation plate between the vibration reduction groove and the hardened floor, and the flexible isolation plate can absorb the vibration from the hardened floor and then transmit it to the vibration reduction groove.
[0013] Furthermore, the bottom elevation of the medium-coarse sand cushion layer is equal to the bottom elevation of the vibration reduction ditch.
[0014] Furthermore, the vibration reduction groove is filled with fine sand.
[0015] The vibration-damping channel of the utility model realizes the absorption of vibration energy through the fine sand inside.
[0016] Furthermore, a cover plate is arranged on the top of the vibration-damping groove, and a sealing strip is arranged between the cover plate and the vibration-damping groove.
[0017] The utility model can effectively prevent ground water from flowing into the vibration reduction groove by arranging the cover plate and the sealing strip, which is beneficial to reducing the compaction of fine sand.
[0018] Furthermore, a concrete cushion layer is provided at the bottom of the vibration reduction ditch.
[0019] The beneficial effects of the utility model are as follows: the structure of the utility model can effectively reduce the impact of the vibration of the surrounding environment on the equipment foundation, so that the equipment foundation can have better dynamic characteristics, and it is easier to meet the allowable vibration displacement peak requirement of the equipment foundation within the time domain, thereby realizing the long-term stable operation of the fully automatic inspection equipment of the coal robot entering the factory, and at the same time can reduce the reinforced concrete engineering volume of the equipment foundation, and achieve good economic benefits.
