Technical field
The present invention relates to cephalic protection field in construction industry, and in particular to a kind of monitoring safety cap of double-layer shell structure.
Background technology
Safety cap is the shallow dome cap of the steel or similar raw material for protecting the crown and wearing, and prevents alluvium from injuring
The protective articles on head.It is made up of cap shell, hat lining, lower cheekstrap and back ferrule.Cap shell is hemispherical, firm, smooth and have certain bullet
Property, hit the impact of thing and puncture kinetic energy and mainly born by cap shell.Certain space is left between cap shell and hat lining, available buffer, is divided
Instantaneous impact is dissipated, so as to avoid or mitigate the direct injury to head.Impact absorption performance, paracentesis resistance energy, lateral rigidity,
Electrical insulating property, anti-flammability are the requirements to the fundamental technology performance of safety cap.Safety cap, its mechanism of action are：Work as operating personnel
When head is impacted by falling object, safety helmet shell, hat lining first decompose impulsive force in moment the whole area of cranium
On, then destroyed using the elastic deformation of safety cap buffer structure, plastic deformation and the structure of permission by most of impact energy
Absorb, the impulsive force for making finally to be applied to person head is reduced to below 4900N, so as to play the work on protection operating personnel head
With.The cap shell material of safety cap is integrally resisted safety cap performance and played an important role.Existing safety cap was actually using
Not only need to prevent the shock of planar object in journey, it is necessary to prevent the shock of sharp objects, and existing safety cap for
The ability of impact resistance need to be improved.
The content of the invention
Present invention aims at a kind of monitoring safety cap of double-layer shell structure is provided, the protecting against shock energy of safety cap is improved
Power.
The present invention is achieved through the following technical solutions：
A kind of monitoring safety cap of double-layer shell structure, including first layer housing and second layer housing, the first layer shell
Body and second layer housing are semiglobe, and the second layer housing is arranged on the downside of first layer housing；The first layer housing
Edge and the edge seal of the second layer housing first layer housing and second layer housing are formed into confined space；Filled out in confined space
Equipped with lubricant.
The reason for existing safety cap bears pressure is the gap for being detained 25mm~50mm between cap shell and hat lining, when
When object hits safety cap, cap shell can be deformed absorbing object impact energy in the presence of impact load, avoid object
Fall and overhead is directly affected, also, cap shell is ellipse or hemispherical, the power born that cap shell overwhelms a little is to surrounding
Transmit, reduced power is buffered up to more than 2/3 by hat lining, whole area of remaining power through hat lining passes to the skull of people
Bone, thus the impetus in cap shell is become the focusing surface on cranium, produced so as to avoid impulsive force on cranium
Raw stress concentration, reduces unit area stress.From above-mentioned, existing safety cap is the obstruction by safety cap, is reduced
The kinetic energy of falling objects, so as to dissolve a part of stress, and remaining strength is to be divided the strength being subject to when hitting
Whole cranium is dissipated to, reduces the pressure being subject in cranium unit area, avoids the damage of cranium, in the mistake of this shock
Cheng Zhong, the direction of strength are not have greatly changed.Said process is preferable for the protection effect of the shock of planar object,
