Abstract

The utility model relates to a safety helmet testing machine which belongs to the field of the testing equipment. An upright column is fixedly connected with a solepiece and an upper transverse girder to form a door-shaped framework. A protective cover fixedly connects with the solepiece. A footing iron pad can be adjusted to connect the underside of the solepiece. Besides, a sensor is fixedly connected with the solepiece; a head mould spirally connects with a head mould bracket; the head mould bracket is fixedly connected with the sensor; a height regulating shaft is fixedly connected with the upper transverse girder by the adjustable way; the lower end of the height regulating shaft connects spirally with an electromagnetic armature; the electromagnetic armature attracts a heavy hammer through magnetic force. The utility model has the advantages of novel structure, convenient portability, simple release component and high accuracy of testing, thereby being used for testing impact on a variety of helmets and for the punching projects.

Description

The safety helmet testing machine
Technical field
The utility model belongs to the test apparatus field.Refer in particular to the checkout equipment that the safety helmet performance is detected.
Background technology
In the testing machine industry, it is a kind of special measurement equipment that safety helmet detects testing machine, testing machine in the past is mostly basically to be that to be fixed to big ground very inconvenient in the equipment handling process, exist to be simply equipped, to carry problems such as moving inconvenience, releasing member complexity, can not satisfy the needs in market.
Summary of the invention
The utility model provides a kind of safety helmet testing machine, and the structure that present detection testing machine exists is simple and crude to solve, problems such as inconvenience, releasing member complexity are moved in carrying.The technical scheme that the utility model is taked is: column 7 is fixed together with base 2, entablature 10 respectively, form portal frame construction, protective cover 6 is fixedlyed connected with base, lower margin parallels 1 is adjustable the connection below base 2, sensor 3 is fixedlyed connected with base, head mould 4 is threaded with head mould support 5, this head mould support is fixedlyed connected with sensor 3, height regulating shaft 11 and entablature 10 adjustable fixedlying connected, regulating shaft 11 lower ends are threaded with electromagnet armature 9, electromagnet armature 9 is by magnetic force adhesive weight 8, and weight carriage 12 is fixedlyed connected with column 7.
Principle of work: impulse test: head mould, Force sensor are placed on the base, Force sensor is installed between head mould and the base, the hat lining of safety helmet is applied on the head mould after transferring to the appropriate location, steel hammer is adjusted to the position of 1m by adjusting the height regulating shaft, and Push switch makes it free drop impact safety helmet.Steel hammer centre-of-gravity path should with head mould center line and sensor sensing dead in line, by the record display instrument measure the suffered impulsive force of head mould.
The puncture test: head mould is placed on the base, the hat lining of safety helmet is applied on the head mould after transferring to the appropriate location, make head mould and steel pricker and electrically contact display device and form an electric closed-loop path, Push switch makes it the steel pricker of 3kg from 1m height free-falling puncture safety helmet, steel pricker the cap point should be at the vulnerable area in the 100mm scope of crown center, and puncture back electric loop conducting electrically contacts the display device display result.
The utility model advantage is: novel structure, be applicable to that the various helmets impact, the detection of puncture project, and conveniently moving, releasing member is simple, accuracy of detection is high.Now use 500Kg base convenient in carrying; Releasing member adopts the magnechuck flexible movements reliable, easy to operate; Precision can reach indicating value 0.5%.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
