Description

Shock-resistant and shock-resistant structure

Technical Field

The invention relates to the technical field of electrical equipment mounting structures, in particular to an impact-resistant and shock-resistant structure.

Background

The impact is transient vibration excitation covering medium frequency to high frequency, and the main characteristics are that the acceleration is large and the action time is short. The energy of the impact vibration is mainly concentrated in the middle and high frequency parts, and the frequency ranges from tens of hertz to thousands of hertz. The shock resistance of the equipment vibration isolator is selected by considering the isolation effect of the equipment vibration isolator in the middle-high frequency part.

Impact resistance, namely, the equipment adopts an impact resistance defense measure, and when the equipment is subjected to the action of external instantaneous impact load, an electrical equipment system is protected to avoid system failure and structural failure. The larger the damping ratio in the aspect of impact resistance, the smaller the natural frequency of the isolation system when damping, the smaller the impact transmission rate and the better the impact isolation performance. The response is a vibration of random amplitude when the input is a broadband random vibration excitation, with a frequency corresponding to the natural frequency of the isolation system. Based on the above principle, a vibration isolator is usually used for the isolation design. Vibration isolators are elastomeric elements that connect equipment and a foundation to reduce and eliminate the vibrations transmitted from the foundation to the equipment. In the impact-resistant design, the selection of the vibration isolator is a key factor, and the important index is the natural frequency. Because the energy of the impact vibration is mainly concentrated in the middle and high frequency parts, the natural frequency of the general vibration isolator is positioned at a low frequency, so that the smaller the impact transmission rate is, the better the impact isolation performance is.

Referring to fig. 1, the anti-impact device mainly comprises a bottom vibration isolator installed between the device and a base (or a foundation frame or a base), and a connecting device installed at the rear upper part of the device to connect the device with a rear support (a rear wall or a rear frame). The lower vibration isolator of the equipment shields or reduces impact, and the rear upper connecting device keeps the equipment stable. The equipment is shielded or shock reduced by the vibration isolator. The upper connecting device keeps the equipment stable after the equipment.

The main forms of the vibration isolator comprise a spring, rubber and a steel friction device or a multi-form combination mode and the like. The connecting device mainly takes the forms of a spring, rubber and the like.

Earthquakes are transient vibrational excitations that are focused primarily at low frequencies, typically within 35 seconds. The energy of the earthquake is mainly concentrated in the low frequency part. The frequency ranges from a few hertz to a few tens of hertz.

The earthquake resistance means that the equipment adopts earthquake-resistant defense measures to protect an electrical equipment system from system failure and structural failure when the equipment is under the action of external earthquake load. In the aspect of earthquake-resistant design, a large-rigidity method is generally adopted for earthquake resistance, namely the natural frequency of a system is required to fall in an interval which avoids a peak region of an earthquake response spectrum and is provided with a certain margin of the natural frequency, so that the excitation frequency and the natural frequency are diverged.

The anti-seismic equipment is generally fixed on a foundation (or a foundation frame and a base) at the bottom of the equipment by a screw (or a bolt) or a welding mode. The anti-seismic function is realized through the rigidity of the equipment.

From the above, it is known that satisfying the vibration of low frequency, medium frequency and high frequency simultaneously is a difficulty point of realizing earthquake resistance and impact resistance, and the frequency of the vibration isolator needs to be balanced to realize the design of earthquake resistance and impact resistance simultaneously, which is very elegant. Since achieving impact resistance requires the isolator to be of low frequency, and this falls well within the maximum amplification zone of the earthquake, the isolator will amplify the seismic excitations. When the excitation frequency is equal to the natural frequency of the vibration isolator, the vibration isolator not only has no damping capacity, but also has an amplification effect on vibration. It can be understood that: the frequency range of the shock-resistant vibration isolator is not beneficial to shock resistance, and the frequency range of the earthquake-resistant system is not beneficial to shock resistance. This is also a difficulty with the simultaneous implementation of the current shock and earthquake resistance requirements.

The prior art can only realize one of two functions of impact resistance and shock resistance, and can not meet the requirement of mutual conversion of the two functions. The risk cannot be ruled out when the device is in an application environment where another functional requirement is required.

Based on this, the present invention provides an impact-resistant and earthquake-resistant structure to solve the above technical problems.

As shown in fig. 2A to 14, in the present embodiment, an impact-resistant and shock-resistant structure is provided, the impact-resistant and shock-resistant structure is used for an electrical apparatus 1, a bottom of the electrical apparatus 1 is mounted on a base 3 through a plurality of bottom vibration isolators 2, and includes a plurality of upper vibration isolators 4 arranged in a transverse direction, and an upper portion of a rear wall of the electrical apparatus 1 is connected to a rear support 5 through the plurality of upper vibration isolators 4;

the outer ends of the two upper vibration isolators 4 at the two ends are detachably connected with the fixing piece 6;

also comprises two fixed connecting rods 7;

one ends of the two fixed connecting rods 7 are respectively detachably connected with the top of the electrical equipment 1, and the other ends of the two fixed connecting rods 7 are detachably connected with the rear support 5;

optionally, the electric appliance further comprises a plurality of bottom connecting plates 8, the upper parts of the plurality of bottom connecting plates 8 are detachably connected with the lower part of the electric appliance 1, and the lower parts of the plurality of bottom connecting plates 8 are connected with the substrate 3.

The impact-resistant and earthquake-resistant structure provided by the invention is suitable for electrical equipment related equipment requiring equipment to have the requirements of impact resistance and earthquake resistance interconversion. The lower part of the equipment is provided with a bottom vibration isolator 2, one end (or one surface) of the bottom vibration isolator 2 is arranged on a base 3 (a basic frame or a base), and the upper part of the back of the equipment is provided with a connecting device which is connected with a back support 5 (a back wall or a back frame). The lower vibration isolator of the equipment shields or reduces impact, and the rear upper connecting device keeps the equipment stable. In order to meet the requirement of earthquake resistance, the connecting device arranged on the rear upper part of the equipment is specially designed, so that the relevant requirement of earthquake resistance can be met. And fixing pieces 6 are respectively arranged at the outer ends of the two upper vibration isolators 4 at the two ends, so that the frequency of the vibration isolators is changed. Meanwhile, the top is also provided with a fixed connecting rod 7, and equipment is fixed through the fixed connecting rod 7.

According to the impact-resistant anti-seismic structure provided by the invention, the upper part of equipment is limited in displacement through the detachable mounting fixing piece 6 and the fixing connecting rod 7, so that anti-seismic is realized. When the equipment is required to have the anti-impact function in practical application, the fixing piece 6 and the fixing connecting rod 7 are not installed on the equipment, and when the equipment is required to have the anti-impact function, the fixing piece 6 and the fixing connecting rod 7 are installed on the equipment. When the natural frequency of the equipment is relatively high, the method can meet the application requirement. If the natural frequency of the equipment is relatively low and cannot meet the application requirement, when the upper part passes through the mounting fixing piece 6 and the fixing connecting rod 7, a connecting plate is mounted between the bottom of the equipment and the base 3 (the base frame or the base) to realize rigid connection between the bottom of the equipment and the base 3 (the base frame or the base), and the cabinet combining equipment adopts the front-back direction to carry out rigid connection between the bottom of the equipment and the base (or the base). The independent equipment can be fixed front and back, left and right or front and back and left and right simultaneously according to requirements.

The bottom vibration isolator is additionally fixedly connected. Increase the natural frequency of system through fixed connection mode, avoid the high earthquake response platform interval, preferentially adopt isolator position and equipment upper portion position fixed connection when the antidetonation demand, the bottom utilizes the joint stiffness of bottom isolator to play a role jointly, and whole modal frequency is higher. If the requirements for earthquake resistance cannot be met through mechanical simulation analysis, fixed connection is added at the bottom vibration isolator. The natural frequency of the system is increased in a fixed connection mode, the interval of a high-earthquake response platform is avoided, and the effect of improving the natural frequency at the back and the hanging ring is obvious through calculation, so that the natural frequency is preferably selected. The above-mentioned fixed connection is removed when there is a need for impact resistance. The shock resistance function is met through the combination of the vibration isolators, and the shock isolation effect is achieved by avoiding the mode of inputting the shock frequency. The fixed connection of the bottom isolator part is increased by changing the frequency of the bottom isolator or enabling the bottom isolator to fail.
