Description
Technical Field
The invention relates to a compression method and a device of a supporting type vibration isolation element, belonging to the technical field of equipment vibration control engineering.
Background
The vibration isolation technology is a vibration control means generally used in equipment engineering, and the vibration isolation can be divided into two types: active vibration isolation and passive vibration isolation. Active vibration isolation-mounting an elastic support such as a vibration isolation element between the equipment generating vibration and the foundation to reduce the transmission of the vibration disturbance of the equipment to the foundation and effectively isolate the vibration of the equipment, and the vibration isolation measures adopted for the equipment of the vibration disturbance products are called active vibration isolation and sometimes called active vibration isolation. In general, vibration isolation of fans, water pumps, compressors and punches including subway rails is active vibration isolation. Passive isolation-mounting resilient supports, such as isolation elements, between the food item and the base to reduce the effect of vibrations from the base on the equipment, so that the equipment can function properly or is not damaged, is referred to as passive isolation, and is sometimes referred to as passive isolation. In general, vibration isolation of instruments and precision equipment is passive vibration isolation, and the nature of mounting vibration isolation elements under houses to prevent earthquake damage is the same.
Whether active vibration isolation or passive vibration isolation, the most commonly applied functional elements are vibration isolation elements, and the mounting, replacement and maintenance of the vibration isolation elements in the whole life cycle all involve the mounting and dismounting operation of the vibration isolation elements. Under the condition that medium and small-sized equipment and space conditions permit, the vibration isolation element can be conveniently disassembled and assembled by hoisting or jacking the whole equipment through a simple hoisting tool or a jacking tool. For the dismounting of large and medium-sized equipment, when the large hoisting equipment cannot reach and cannot hoist or lift the equipment, the supporting type vibration isolation element is dismounted, and if the supporting type vibration isolation element does not have a self-compression function, the following problems can be encountered:
1. the dismantling is difficult: the vibration isolation element is in a compression state due to bearing reasons in an installation state, and the elastic force generated by compression causes large static friction force between the upper surface of the vibration isolation element and the installation position of equipment and between the lower surface of the vibration isolation element and the ground, so that the vibration isolation element is extremely difficult to extract by a compulsory means;
2. the installation is difficult: under the condition that the installation state of the equipment is not changed, the newly replaced vibration isolation element needs to change the height of the vibration isolation element per se and reduce the height of the vibration isolation element below a 'supporting compression height', and the vibration isolation element can be plugged, positioned and assembled in a limited space state.
3. Jacking risk: for large-scale equipment, if hoisting equipment cannot be adopted, local jacking can be carried out on equipment legs through jacking equipment such as a large-load jack, and a space is formed at the installation target position of the vibration isolation element; in this case, if the equipment is not lifted integrally, the local lifting may cause concentrated stress on the local part of the equipment, and the machine foot structure of the equipment is likely to be damaged.

Detailed Description
As shown in fig. 1 and 2, from the description of the background art of the present invention, it can be seen that the problem to be solved by the present invention is to compress the height or thickness of the vibration isolation member 1 in the case where the supporting type vibration isolation member 1 having the extremely strong elastic support rigidity cannot directly apply pressure to the upper top surface of the upper cover plate 2 and the lower top surface of the lower cover plate 3. To solve the above problems, the present invention first provides the following methods:
as shown in figure 1, a compression method of a supporting type vibration isolation element is that a lower pull mechanism temporarily connected with an upper cover plate 2 is built below the outer edge of the upper cover plate 2 of the vibration isolation element 1, an upper pull mechanism temporarily connected with a lower cover plate 3 is built above the outer edge of a lower cover plate 3 of the vibration isolation element 1, when the compression method is applied, a downward force and an upward force are simultaneously applied to the lower pull mechanism and the upper pull mechanism respectively, so that the upper cover plate 2 and the lower cover plate 3 are respectively subjected to a downward pulling force and an upward pulling force, and the upper cover plate 2 and the lower cover plate 3 respectively compress the vibration isolation element 1 from the upper end and the lower end oppositely to force the vibration isolation element 1 to reduce the height of the vibration isolation element 1. In this way, it is possible to pull out the compressed vibration insulating element 1 from the installation space in which the height cannot be changed and to place a new vibration insulating element 1, which has been compressed in the same manner as described above, into the installation space in which the height cannot be changed.
The downward force and the upward force are simultaneously applied by the downward pulling mechanism and the upward pulling mechanism respectively, the stress point of the downward pulling mechanism of the upper cover plate 2 is positioned under the stress point of the upward pulling mechanism of the lower cover plate 3, a jack 4 is arranged between the stress point of the downward pulling mechanism and the stress point of the upward pulling mechanism, the jack 4 is used for jacking, and reverse force is applied by the stress point of the downward pulling mechanism and the stress point of the upward pulling mechanism at the lower end and the upper end of the jack 4. Thus, the forces in two directions which are originally to be pulled inwards in opposite directions are converted into the forces in two directions which are reversely supported from inside to outside, and then the jack is used, so that the operation becomes simple and convenient.
The lower pull mechanism is temporarily connected with the upper cover plate 2, the upper pull mechanism is temporarily connected with the lower cover plate 3, the lower pull mechanism and the upper pull mechanism respectively use a connecting part with external threads, and threaded holes matched with the external threads of the connecting part are punched in the set positions of the upper cover plate 2 and the lower cover plate 3 in advance. When the device is applied, the lower pull mechanism and the upper pull mechanism are respectively in threaded fit connection with the upper cover plate 2 and the lower cover plate 3 by utilizing respective connecting parts. The thread matching connection mode is divided into two situations, one is that a thread connecting hole is punched when the upper cover plate 2 and the lower cover plate 3 are produced for use when the upper cover plate and the lower cover plate are installed and removed; the other situation is that the upper cover plate 2 and the lower cover plate 3 are not perforated in advance during production, temporary perforation is needed in an engineering field, and of course, conditions suitable for perforation are needed in the engineering field.
The lower pull mechanism is temporarily connected with the upper cover plate 2, the upper pull mechanism is temporarily connected with the lower cover plate 3, the lower pull mechanism and the upper pull mechanism both use connecting parts with welding pins, and during application, the lower pull mechanism and the upper pull mechanism are respectively in welding connection with the upper cover plate 2 and the lower cover plate 3 by using the welding pins of the respective connecting parts. The method is applied to the upper cover plate 2 and the lower cover plate 3, no hole is punched in advance during production, temporary punching is not suitable for an engineering field, and then welding connection is the best connection mode.
