Concrete technical scheme of the present utility model is as follows:

Container wood floor intensity detecting device, including afterburning parts, dynamometry parts and display instrument; It is characterized in that, described afterburning parts are made up of handle, inner screw, ut socket and lever; Described dynamometry parts are a S type pressure transducer; Described handle connects inner screw, is cased with ut socket outside described inner screw; Described handle is rotated clockwise driving inner screw to rotate so that inner screw precession ut socket carrys out activation lever, and stress is transferred to S type pressure transducer upper end by lever drives U-shaped connector simultaneously; The backer roll that described S type pressure transducer lower end is passed through to be fixed in the above is by the midpoint of power effect to batten test specimen end face; Suffered stress check calculation is become analogue signal to send display instrument to by described S type pressure transducer.

In such scheme, the model that described S type pressure transducer adopts is TSB-M. Its rated capacity 2T, maximum error is less than 1Kg (10N)

In such scheme, described display instrument adopts HT600 weighing controller. It has peak value and preserves function.

This utility model is little due to volume, lightweight, unpowered equipment, easy to operate, is therefore applicable to the intensity of production scene test board products, for ensureing that product quality provides foundation.

Accompanying drawing illustrates:

This utility model is further illustrated below in conjunction with the drawings and specific embodiments.

Fig. 1 is structure sectional view of the present utility model.

Detailed description of the invention:

For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.

As it is shown in figure 1, container wood floor intensity detecting device described in the utility model, critical piece has afterburning parts, dynamometry parts, display instrument matrix section. Concrete structure is as follows:

Afterburning parts are by handle 14, inner screw 12, ut socket 11, and lever 2 grade forms, handle 14 rotationally clockwise, inner screw 12 is driven to rotate, owing to ut socket 11 lower end is to be fixed on the bolt 17 crossing left and right side support by M20 oscillating bearing 21, bolt 17 nut 18 tightening, limit shaft sleeve 20 clamping of oscillating bearing both sides, limit bearing to move left and right, therefore inner screw precession ut socket can only move downward, and drive what female thread cutting ferrule 13 and cutting ferrule bearing 15 be pressed downward against lever 2 to add force, lever rotates around fulcrum 3, force is positioned at lever 2 and drives U-shaped connector 4 that power is transferred to the upper end of pressure transducer 5, the backer roll 6 that sensor lower end is passed through to be fixed in the above is by the midpoint of power effect to batten test specimen end face, bottom surface, batten test specimen two ends is shelved on backing roll 9, time afterburning, test specimen is subject to curved until destroying.

Its afterburning principle is that handle is rotated by manpower, it is screwed into ut socket by inner screw, the effect of similar screw jack, what the power of amplification was pressed down lever adds force, adding force to the distance of fulcrum is resistance point to five times of pivot distance, can power being put again five times greater again, the power on batten test specimen that is therefore loaded into is up to 1000Kg (10000N).

Dynamometry parts are S type pressure transducers 5, and model is TSB-M, rated capacity 2T, accuracy class C3, and analog signal output is to digital displaying meter.

Display instrument adopts HT600 weighing controller, and instrument adopts 24V D.C. regulated power supply to power.

It addition, in Fig. 1, panel is upwards provided with instrument 33, device also includes power supply 34; The analogue signal of sensor output converts digital signal to through A/D convertor circuit, demonstrates force value Kg or N after amplification on LED display, and when pressure reaches peak value, instrument peak value can keep automatically, and dynamometry global error is at 1Kg (10N) below.

Certainly, Fig. 1 also includes for the combination of this device and safe handling needs other part of arranging: base 10, cutting ferrule home record 16, little pin 19, test specimen positioning baffle 22, opening europium 23, fasten the nut (24,25,27,28) of side support, spacing rustless steel has strong market potential 26, longitudinal spacing pin 29, spacer pin packing ring 30.

This device possesses following characteristics:

(1) volume is little, long 450cm, wide 400cm, high 450cm;

(2) lightweight 15Kg, for alleviating weight, dual-side support aluminium alloy 6061 makes;

(3) conveniently moving, can be placed on plant site and use;

(4) intensity detection is quick and precisely.

Said apparatus use procedure is as follows:

1. first container wood floor intensity detecting device is placed on the smooth ground in workshop or warehouse before using, keep bottom surface level, check that whether afterburning component activity is flexible, connect 24V power supply, by display instrument back to zero knob, making display output valve is 0Kg (0N);

2. test specimen intercepts: at least intercepting 5 test specimens on every model for test, test specimen should be uniformly distributed, and test specimen dash board grain direction is identical with the direction on the long limit of test specimen, piece lengths L=300mm, specimen width b=50 �� 1mm, specimen thickness h=28 �� 0.5mm;

3. rotary handle, makes lever rise, and then from bottom surface, this device front end, the test specimen cut is against backing roll and fills in loading position, and baffle plate is encountered in test specimen front end. Backing roll and backer roll diameter are 12.7mm, and the horizontal range between backing roll center and backer roll center is 125mm, and test specimen end face is 25mm to the horizontal range at backing roll center, baffle position regulate;

4. rotary handle, makes lever decline, and when the turning handle that should remain a constant speed after backer roll contact test specimen, makes backer roll decline with 10mm/min speed, until test specimen destroys, records the maximum pressure value that now instrument shows, be accurate to 1Kg (10N);

5. qualification determination, the breakdown pressure >=690Kg (6900N) of single test specimen, then judge that this test specimen is qualified.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.
