Description
Technical field
The invention belongs to protective articles strength test field, specially a kind of self-absorbing filtering type protective respirator headband is strong
Spend testing machine.
Background technology
Self-absorbing filtering type protective respirator, it is the filtering type respiratory protection that part gas-flow resistance is overcome by wearer's breathing
Articles for use.It is different according to protection object, suction-self filtering type against particle respirator and self-absorbing filtering type gas defence mask can be divided into.The former
For protecting suspended particulate substance, poisonous and hazardous gas that the latter is used to defending endangering respiratory system or eye face, steam or
Grain thing.Headband is the part for mask to be fixed on to head.
GB 2626-2006《Protective respirator suction-self filtering type against particle respirator》With GB 2890-2009《Breathing
Protect self-absorbing filtering type gas defence mask》The technical requirements of all correct band strength are provided.
The shortcomings that prior art：
1st, efficiency is low：During experiment, mask is fixed and can not rotated in the plane, and headband is also kept flat.Counterweight worked hard in glove with pulley and steel
Silk is withheld with head to be connected and hangs.After 1 headband test terminates, artificially steel wire must be untied, adjust mask angle and fixation, will
Steel wire is buckled with another headband to be connected, then in pulley lower wire one hang up counterweight.Mask typically has 6 headbands, every time
Retighten mask, change headband, lose time, influence operating efficiency.
2nd, it is laborious：After counterweight is placed on into counterweight hook above, it must lift to hang over by manpower and be buckled with headband on the steel wire being connected, be taken
Counterweight causes high effort for.
3rd, potential safety hazard：Weight box can not raise, during experiment, if failed sample or other factors cause counterweight
Drop, testing crew may be damaged.
4th, difficult control：The bad control of counterweight process is hung, the power of transient acceleration is easily produced, sample is formed and impacted,
Influence result of the test accuracy.
The content of the invention
It is an object of the present invention to provide a kind of time saving, laborsaving, safe, easily controllable self-absorbing filtering type protective respirator head
Band strength testing machine.
The present invention adopts the following technical scheme that realization：
A kind of self-absorbing filtering type protective respirator headband strength-testing machine, including base I and base II.
Model support is fixed with the base I, head model, the head mould are movably installed with the model support
Type side connection mask fixing band, opposite side are provided with buckle, after placing mask to be measured on the head model, its side
Mask fixing band is tensed after bypassing mask by buckle, and mask is fixed on head model.
Lifting support and operation support are fixed with the base II；Both sides are respectively equipped with slip rail in the lifting support
Road, its top are provided with fixed pulley；Transmission device is installed on the operation support；Steel wire rope is bypassed on the fixed pulley, it is described
Steel wire rope one ends wound on transmission device, the other end hook is installed, the hook is lifted with weight box by hook ring, described
For weight box between model support and lifting support, side corner of the weight box between lifting support passes through slip
In sliding rail in bearing insertion lifting support.
In use, 1, by mask cover body face upward be arranged on head model on, cover body is fixed with snap ring, now mask
Headband（Non-free end）Down.2nd, the counterweight of certain mass is put into weight box.3rd, transmission device positive action is by steel wire rope
Pack up, weight box rises, and stops until counterweight hooks when rationally buckleing connecting portion close to corresponding headband.4th, counterweight is hung over to be measured
After on headband ring, transmission device counteragent transfers steel wire rope, and weight box declines, until counterweight just leaves bottom and whole
Suspension acts on headband and buckled.5th, after certain time, transmission device positive action packs up steel wire rope, and weight box moves up,
Until counterweight contact bottom and headband stopping stress.6th, whether record sample there is phenomena such as being broken and slipping.7th, head is rotated
Model, headband ring is changed, repeat aforesaid operations, until completing all headband experiments.8th, after off-test, weight box is adjusted to most
It is low.
The device has the following advantages that：
1）It is time saving：The head model of mask fixed station can carry out Arbitrary Rotation according to headband test sequence, only need gently
It is replaceable headband to rotate head model, can save the time, improves operating efficiency.And counterweight is hung directly from headband and buckled,
The trouble of connection steel wire is saved, it is very convenient.
2）It is laborsaving：Transmission device is mounted with, weight box has pulley, can carry out descending operation to weight box, counterweight is put
It can easily lift in weight box, save manpower.
3）Safety：Transmission device can keep weight box to hang, during experiment, even if counterweight leaves bottom but all in case
It is interior, if counterweight drops, it also can only fall in case, testing crew will not be injured, ensure that experiment security.
4）It is easily controllable：Device can be by controlling the rotation speed of wind, to control the speed of counterweight suspension process.It is slow
It is slow to shake wind, prevent the power of transient acceleration is formed to sample from impacting, improve the accuracy of result of the test.
The present invention provides self-absorbing filtering type protective respirator headband strength-testing machine, meets GB 2626-2006《Breathing
Protective articles suction-self filtering type against particle respirator》With GB 2890-2009《Respiratory protection self-absorbing filtering type gas defence mask》In
The test request of headband intensity, the efficiency that efficiently solves current self-absorbing filtering type protective respirator headband strength test is low,
Arduously, it is difficult to control, the problems such as potential safety hazard be present.The invention can make mask cover body sample Arbitrary Rotation, and counterweight can be entered
Row descending operation, testing crew is not injured when counterweight can be protected to drop, can to counterweight hang process be controlled, have it is time saving,
Laborsaving, safe, easily controllable substantive distinguishing features and marked improvement.The device technique easily reappears, and improves operating efficiency, drop
Low labor intensity, testing crew safety is ensure that, improves the result of the test degree of accuracy.
