Description
Technical field
The invention belongs to safety belt test device, electrical equipment technical fields, and more specifically, more particularly to one kind is used for
The pulling force fatigue experimental device that falls of power construction safety belt.
Background technology
Safety belt is widely used in the fields such as building, electrician, vehicle, high-altitude activity, is the weight to guarantee personal safety
Accessory is wanted, therefore, the load-bearing capacity of safety belt is particularly significant, needs to carry out it shock of a fall fatigue survey before safety belt manufacture
Examination.
By retrieving the patent of such as Patent No. CN201620267354.7, a kind of safety belt buffer test is disclosed
Device, including testing jig, the buffer to be measured, lifting gear, detection device, the console that are connect with iron man；The lifting gear
It is respectively set including two sliding slots for being vertically arranged in testing jig both sides and stretching testing jig upper end respectively, horizontal positioned and both ends
Reel, the rope that decelerating motor drives are held and pass through on the tester rack to slide bar, setting in two sliding slots；Two cunnings
It is provided with pulley between the upper end of slot；The mounting bracket for fixing iron man is provided on the slide bar；One end of the rope around
It crosses pulley to connect with mounting bracket, the other end is wound on reel；The detection device includes the sensing that setting is held on the tester rack
Device；The console is connect with decelerating motor, cylinder, pickup wire respectively；The present invention is by regarding iron man as load from eminence
It freely falls, can really acquire out every main performance data of safety belt buffer, and DATA REASONING is accurate.
Such as patent of Patent No. CN202916063U again discloses a kind of multi-functional impulse detection dress of safety belt
It sets, by column 1, two-layer platform guardrail, floor cross member, bottom longeron, three beam, three layers of longeron, lifting lug 1, support post, branch
Support crossbeam, column 2, electric hoist, winder, lifting lug 2, turnover panel, one layer of platform, sensor, ladder, ceiling, lightning arrester, experiment
Baffle, release, rubber people mould, guide chain, conducting wire and computer are formed.Rubber people's mould is fixed on one layer of platform, using leading
Rubber people's mould is placed on turnover panel by chain, and the railing class safety belt dressed with it is fixed on lifting lug 1, with winder and
Electric hoist by rubber people's mould promoted and connect with release, hook is connect with the release under lifting lug 2, the conducting wire on release and
Computer connects.When release discharges rubber people's mould, moment impact force value is transferred to computer by sensor, and computer carries out data
Collection analysis makes the examining report for the suspension safety belt overall dynamics Road test that falls.
Based on patent at above-mentioned two and prior art people is combined to find, existing test device is mostly using lifting
Machine carries out lifting shock-testing, need to wind steel wire rope since elevator is completed rear elevator every time, strength youngster causes its test
Interval time is longer, so that bump is tested less efficient, and impact the shock buffer structure optimization design of clump weight not
It is enough reasonable, after clump weight dives downwards and pulls apart lifting rope impact, it violent heavy can directly strike against on substrate, make
It influences to use at clump weight gross distortion, and the disintegrating slag that generates can splash the problem of hurting sb.'s feelings when hitting.
Then, it in view of this, being studied improvement for existing structure and missing, provides a kind of for power construction peace
The pulling force fatigue experimental device that falls of full band, to achieve the purpose that with more more practical value.
Invention content
In order to solve the above technical problem, the present invention provides a kind of pulling force fatigue examinations of falling for power construction safety belt
Experiment device, longer to solve existing safety belt test device to test interval time, bump is tested less efficient, and counterweight
Easy the problem of the hurting sb.'s feelings of splashing of the shock disintegrating slag of block.
Purpose and effect of the present invention for the pulling force fatigue experimental device that falls of power construction safety belt, by detail below
Technological means is reached：
A kind of pulling force fatigue experimental device that falls for power construction safety belt, including support mounting bracket, motor installation
