Description
Technical field
Impact test suspension is the utility model is related to, belongs to a kind of test equipment, can be applied to adventure playground
Pad impact test.
Background technology
Padded for adventure playground and require to carry out impact test.Deltec companies produce a kind of HIC impact devices, but still
It is to be modified.（1）Impulse form is freely falling body mode, but impact head is dome-type impact head, with standard《EN 1177-2008
Impact the measure of damping recreation ground paving damage dropping highs》It is it is required that inconsistent（2）Release system is electromagnetic releasing system, can
There can be certain negative influence to release, because electromagnet release system there may be Magnetic hysteresis, or because release part
Magnetization phenomenon be present, release initial velocity may be caused to be weakened, cause impact velocity relatively low, it is inclined to ultimately result in damage dropping high
It is high.（3）Using there is linear acceleration transducer, signal wire may cause impact head in test process to rotate.Because impact head is non-
Ball-type, therefore its sensor can not realize that the centre of sphere is installed, and in impact process acceleration transducer can not be ensured through overshoot
Hit in horizontal plane vertical line a little, test data correctness can not be ensured.Rotation caused by impact head rotation in test process adds
Speed may influence test result, increase the uncertainty of measurement.（4）Equipment is without height measurement function, by tester
Shock height measurement is carried out using tape measure, precision is relatively low, can not ensure to measure the accuracy of height, influence final testing result
Correctness, while also introduce uncertainty for test result.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, accurate impact test suspension of measurement.
A kind of impact test suspension, it is connected for the impact head with impact test system and release system, it is special
Sign is:Including device framework, be installed on device framework arrangement for adjusting height and height measuring device composition；Wherein height
Measurement apparatus is located at device framework top, and it includes fixed pulley and the encoder for identifying fixed pulley rotation situation；It is wherein high
Degree adjusting means is located at device framework middle and lower part, and it includes ratchet, and the hand crank being connected with ratchet, in addition to a rope
Rope, the rope one end are connected with ratchet, and the other end is connected after bypassing the fixed pulley in height measuring device with release system.
The method of the impact test suspension, it is characterised in that:Rope is driven by hand crank to adjust impact
The height of head；Rope slides with fixed pulley Complete Synchronization without relative；The number of turns that encoder record fixed pulley turns over, fixed pulley is turned
The number of turns crossed is scaled rope displacement, and then is scaled the height of impact head lifting, and this is highly tested for impact head distance
The actual relative altitude of point.
The utility model additionally uses the height adjusting system of encoder instruction, ensures the accuracy of shock height measurement.

Embodiment
A kind of impact test apparatus as Figure 1-5, including device framework 2, impact head and release system 4, impact head height
Degree regulation and measuring system；Above-mentioned impact head and release system are installed on device framework 2, and it is by impact head and release device group
Into；Wherein impact head generally spheroid, is made up of episphere 16 and lower semisphere 17, and episphere top has rectangular channel 15, rectangle
Suspended axle 14 is installed in groove, wireless triaxial acceleration transducer is installed in spheroid；Wherein release device includes housing 9, housing
Top is provided with hitch point 8, and for outer inframe by bearing pin mounting hook 12, outer inframe is also equipped with motor 10, motor output shaft peace
Equipped with the driving lever 11 that can stir hook；The housing low profile and the rectangular reservoir shape on impact head top of above-mentioned release device are mutual
Matching, outer frame bottom just extend into rectangular channel and can not rotated against, and the hook portion hook of the hook 12 of release device is in impact head
Suspended axle 14;Above-mentioned impact grease head highness regulation and measuring system are installed on device framework 2, and it is by arrangement for adjusting height and height
Measurement apparatus forms;Wherein height measuring device is located at the top of device framework 2, and it includes fixed pulley 19）Determine cunning with for identifying
Take turns the encoder 18 of rotation situation;Wherein arrangement for adjusting height is located at device framework middle and lower part, and it includes ratchet 20, and and spine
The connected hand crank 21 of wheel, in addition to a rope, the rope one end are connected with ratchet, and the other end bypasses height measuring device
In fixed pulley after be connected with the hitch point of arch outside release device.Impact test apparatus, in addition to system power supply, in addition to
Control system, control system is including in the impact release control module being connected with motor in release device and height measuring device
The connected shock height display module of encoder, in addition to be wirelessly connected with Wireless Acceleration Sensor in impact head
Acceleration signal acquisition module, in addition to computation analysis module.
The impact test method of the impact test apparatus, process procedure below:Rope is driven to adjust by hand crank 21
Save the height of impact head；Rope slides with fixed pulley Complete Synchronization without relative；Encoder 18 records the number of turns that fixed pulley 19 turns over,
The number of turns that fixed pulley is turned over is scaled rope displacement, and then is scaled the height of impact head lifting, and this is highly impact
Actual relative altitude of the head apart from measured point；Motor 10 drives driving lever 11, and hook 12 is dialled from release at the suspension of impact head
Impact head；The acceleration information of impact head is measured by wireless triaxial acceleration transducer.
A) impact head and its delivery mode
Using spherical impact head mould, head mould carries the wireless triaxial acceleration transducer for meeting standard requirement, employs band
There is the hook release device of certain guide function.Dependency structure is as shown in Figures 2 and 3.Wherein acceleration transducer barycenter is bag
