Anti-vibration pad for whole-body vibration

Abstract

The invention belongs to the technical field of whole-body vibration protection, and provides an anti-vibration pad for whole-body vibration. The anti-vibration pad comprises a wear-resisting layer (1), an anti-vibration layer (2) and an anti-slip layer (3), wherein the wear-resisting layer (1) is located at the top layer, the anti-vibration layer (2) is located at the middle layer, and the anti-slip layer (3) is located at the bottom layer; and an anti-slip grain surface (4) is arranged on the wear-resisting layer (1), and the anti-vibration layer (2) is made of foaming polystyrene. The anti-vibration pad has the beneficial effects that whole-body vibration level, especially low-frequency whole-body vibration level, of a working site of a power station can be reduced obviously; splicing and removing and installing of the anti-vibration pad are convenient, and use of working sites with different areas can be met; needs of the power station for site installation and daily maintenance can be met, and good removing and installing convenience is achieved; and a good anti-slip effect can be provided for site operating persons.

Description

technical field [0001] The invention belongs to the technical field of whole-body vibration protection, and relates to a vibration-damping pad used for slowing down the whole-body vibration of a power station. Background technique [0002] The impact of vibration on the human body is divided into whole-body vibration and local vibration. The whole-body vibration is caused by the vibration source (vibration machinery, vehicle, movable work platform) through the supporting parts of the body (foot and buttocks), and the vibration is transmitted along the lower limbs or torso. Transmission of the whole body mainly causes indirect vibration. Contact with strong whole-body vibration may cause damage or displacement of internal organs, changes in peripheral nerve and blood vessel functions, and may cause various types of tissue and biochemical changes, resulting in tissue malnutrition. Such as foot pain, fatigue of lower limbs, weakened dorsum pulse of the foot, and lower skin temp...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no vibration-absorbing pad designed and developed for the hazards of whole-body vibration in power stations. Similar products mainly include vibration-absorbing insoles and shock-absorbing seat cushions: vibration-absorbing insoles are mainly designed and developed for athletes. Although vibration-absorbing insoles have good comfort, However, for the on-site operation characteristics of power stations, the vibration-absorbing insoles have the following deficiencies: The vibration-damping insoles are not designed and developed for power stations, and their vibration-reducing effects on the whole-body vibration hazards of power stations are not clear, especially for power stations. There is a whole body vibration hazard at a low frequency of 0.5-1.6Hz

The vibration-absorbing seat cushion is mainly designed and developed for the driver. Although it can reduce the whole-body vibration level generated by the driver while driving the vehicle and improve driving comfort, for the on-site operation characteristics of the power station, the shock-absorbing seat cushion There are the following deficiencies: 1. The driving posture of the driver is generally a sitting posture, while the working posture of the on-site operators of the power station is generally a standing posture. Different working postures may affect the vibration reduction effect of the shock-absorbing seat cushion; 2. The vehicle is in a sitting posture. The frequency spectrum characteristics during driving are not exactly the same as those when the power station is running. Therefore, the vibration reduction effect of the shock absorbing seat cushion for the whole-body vibration hazard of the power station is not clear; 3. The operating area of ​​the power station is large, and there is a whole-body vibration hazard The area is widely distributed, and the vibration-absorbing seat cushion cannot meet the needs of large-area laying at the power station operation site

In summary, neither the shock-absorbing insoles nor the shock-absorbing seat cushions are suitable for the protection of whole-body vibration hazards in power stations.
