Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail：
It is of the invention that mainly there is carrying platform, transverse shifting function, function, test loading function and vehicle phase is moved up and down
To positioning function etc..
Carrying platform：It is the installation foundation of whole device parts, while and be the basis that the device is connected with vehicle, can
Whole load testing machine is securely attached on the load bearing component of transport vehicle by forms such as welding and bolt connections, so as to reality
Now the removable chemical industry of the device is made.The crossbeam that is welded using high-strength panel of the present invention and slideway as carrying platform,
Reinforcement is provided with thereon.Carrying platform is connected with transport vehicle longeron by high-strength bolt.
Required according to the intensity detection relevant criterion of automobile and trailer protector, the position that loading is needed in test is not
A bit fixed, the method for meeting this requirement has two kinds, and a kind of is by mobile sample car or equipped with the load testing machine
Transport vehicle realizes the requirement loaded to diverse location；Another kind is by the horizontal and upper and lower of the load testing machine itself
Movement come realize to different load(ing) points loading requirement, Comparatively speaking the operation of the implementation of the latter is relatively simple.This
Bright employing the latter is designed manufacture.
Transverse shifting function：Implementation has various, can be automatically (including Motor drive, hydraulic-driven etc.) or manual
(hand leading screw, hand push slip etc.) form etc., and need to realize positioning locking function.Present invention application hydraulic driving mode, leads to
The fluid motor-driven pinion rotation crossed on charger, gear are engaged with the tooth bar on the carrying platform, with reference to sliding
Roller on component is coordinated with the slideway on carrying platform, realizes the transverse shifting of whole load testing machine, using hydraulic pressure system
The location requirement of the whole charger of hydraulic lock functional realiey in system.
Move up and down function：With transverse shifting functional similarity, can be by automatically (including Motor drive, hydraulic-driven etc.) or hand
Forms such as dynamic (hand leading screw, hand push slips etc.) is realized, and is needed with positioning locking function.The present invention is double using hydraulic-driven
Acting hydraulic actuator drives quadric chain to realize moving up and down, and meets double leval jib machine using the hydraulic pressure lock function in hydraulic system
The location requirement of structure.
Test loading function：Test loading function is to provide the pith of test on-load pressure, can pass through hydraulic pressure, gas
Pressure and frame for movement (leading screw, mechanic jacks etc.) etc. are realized, while itself will possess enough intensity requirements, to meet loading
Test requirements document.Because of GB 11567.1-2001《Automobile and trailer side shield are required》With GB 11567.2-2001《Automobile and extension
Car rear lower requirement of shelter》Test needed for test pressure maximum be respectively 1KN and 100KN, the two is widely different, so
For the charger of side shield test can be realized using small-sized hydraulic oil cylinder, cylinder or mechanical mechanism.Then lower portion
On-load pressure required value is higher, and it is more suitable to be loaded using hydraulic jack.May also be employed suitable hydraulic system, hydraulic jack and
Pressure sensor completes the loading tasks of above-mentioned two test on same charger, or arranges on same charger
Loading force size reforming unit, by changing pressure sensor and pressure head, while realizing the loading tasks of two tests.The invention
Loading function is realized using hydraulic jack, is connected with quadric chain, front end connects pressure sensor and pressure head.
Vehicle relative positioning function：As in test loading, vehicle can be promoted because of loading force, so as to affect test knot
Really, so needing charger is fixed with detected vehicle, implementation method can be using fixing charger and tested respectively
Measuring car, it is also possible to charger is connected as one with detected vehicle, realizes being relatively fixed for the two.The invention is using after
Person is designed and is made, and has been respectively mounted high intensity hook at the left and right two ends of bearing beam, by meeting intensity requirement
Rope or annular chains detected vehicle and experiment loading unit are connected as one, realize being relatively fixed for the two.Herein
The connection member applied requires that deflection is as little as possible at the trial, to reduce its impact to result of the test.
For side shield strength test, because its loading force only has 1KN, the power is not result in charger with tested measuring car
Relative motion, so for side shield strength test charger can be not provided with vehicle relative positioning part.
Fig. 1, Fig. 2 and Fig. 3 are one embodiment of the present of invention, and the vehicle carried type vehicle protection load testing machine is flat by carrying
Platform, Transversal moving devices, move up and down part, test loading component and vehicle relative positioning part etc. composition.
