Fig. 2 is a side view of the present utility model.
Fig. 3 is a upward view of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples the portable ground friction coefficient measuring instrument that the utility model provides is described in detail.As shown in Figure 1 to Figure 3: a kind of portable ground friction coefficient measuring instrument, comprise dynamometry part 1 and Slipper 2, dynamometry part 1 is little range, high-precision hand-held pointer push-and-pull dynamometer, and Slipper 2 is made up of slide plate 2.1, balancing weight 2.2 and block rubber 2.3 3 parts; The bottom surface of slider plate 2.1 is pasted with described block rubber 2.3, and balancing weight 2.2 is placed on the end face of described slide plate 2.1, and the center fixation of a side of slide plate 2.1 has an annular screw 3, hook 4 clasp joints of annular screw 3 and described dynamometry part 1.
As shown in Figure 1, present embodiment is described is to use once once simply the measuring the floor tile skin-friction coefficient that portable ground friction coefficient measuring instrument carries out.Shown in Fig. 2-3, this dynamometry part of selecting for use in measuring 1 is selected KTL-100 type dynamometer, range 0.5-100N, and scale division value is 0.5N, stayed mast is apart from bottom surface 16mm.The length and width high parameter of slide plate 2.1 is respectively 100mm, 100mm, 20mm, the length and width height of balancing weight 2.2 and the parameter of quality are respectively 100mm, 100mm, 15mm, 11N, the length and width high parameter of block rubber 2.3 is respectively 37mm, 37mm, 3mm, and its IRD hardness is selected 90 ± 2 specification in addition.Slipper 2 surface brush coating water-proofs are handled.One side is fixed an annular screw 3 and is connected with the hook 4 of dynamometry part 1 below apart from bottom surface 13mm place.The bottom surface is apart from 31mm(centre position, annular screw 3 one side) paste block rubber 4 with chloroprene rubber adhesive agent.
Use this portable ground friction coefficient tester to test according to the following steps:
One, the experiment brick is prepared:
Experiment should be carried out being not less than on the brick surface of 100mm * 100mm.When testing little lattice brick, should become a suitable plane to they pavings, clean the brick surface, treat that the brick surface experimentizes after the clean dry fully again with neutral cleaning solution.
Two, slide block is prepared
No. 400 silit are tiled on the table top, and along continuous straight runs pulling Slipper 2 makes the displacement of block rubber 2.3 on sand paper on its bottom surface be about 100mm.Slipper 2 is turned over 90 ° repeat above-mentioned bruting process again 4 times altogether in surface level.Brush away the chip that grinds off in the bruting process with soft brush, repeat above process in case of necessity till the gloss of removing block rubber 2.3 surfaces fully.

Four, result of calculation
Utilize formula F
d=R
d/ nW calculates the static friction factor on experiment brick surface.
In the formula: F
dThe coefficient of static friction values on-test brick surface; R
d-4 pulling force reading sums, unit is N; N-pulling number of times; W-Slipper adds the general assembly (TW) of 11N, and unit is N.
