Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
As shown in Figures 1 to 4, the fishback strained detection device of a kind of staircase, for the crowded grip force between detection comb plate 100 and step 101.The fishback strained detection device of described staircase includes the guide 1 being arranged on step 101, be installed on guide 1 strain gauge 3 and the pushing frame 2 being movably arranged on guide 1.Described pushing frame 2 is slidably connected with guide 1.Described pushing frame 2 can side-to-side movement under the guide effect of guide 1.In the present embodiment, described guide 1 is the sleeve of inner hollow, and described pushing frame 2 is located in sleeve.The bottom of described sleeve is fixedly installed clamp 4, and described clamp 4 is L-shaped, and the corner that described clamp 4 is installed on step 101 makes sleeve be removably mounted on step 101.
Described pushing frame 2 includes catch bar 5, the top plate member 6 being fixedly mounted on catch bar 5 end and the bolt 7 threadeded with catch bar 5.Described top plate member 6 takes the shape of the letter U, described top plate member 6 includes the upper plate 61 be arrangeding in parallel up and down and lower plate 62 and connects upper plate 61 and the side plate 63 of lower plate 62, forming groove between described upper plate 61, lower plate 62 and side plate 63, the end of described fishback 100 contacts with side plate 63 in stretching into groove.Described bolt 7 is erected on catch bar 5, and described bolt 7 is positioned near the end away from fishback 100 of catch bar 5.
The top being fixed on sleeve held level with both hands by described strain gauge 3, and upward, the force side of described strain gauge 3 stretches out that dial plate and bolt 7 is fixing to be connected to the dial plate of strain gauge 3.
The present invention is in use, first the one of comb platelet on the fishback 100 of staircase head and the tail end is dismantled, being inserted by clamp 4 in the gap between fishback 100 and step 101, clamp 4 is fitted in the corner of step 101, and top plate member 6 contacts with the end of fishback 100.Driving step 101 to move near the direction of fishback 100 by external equipment such as hand turning, described step 101 withstands clamp 4 band moving sleeve near the motion of the direction of fishback 100.Sleeve drives strain gauge 3 near the motion of the direction of fishback 100, and bolt 7 is held in the force side of strain gauge 3 makes side plate 63 offset with fishback 100, and strain gauge 3 detects the stress size of fishback 100.
Visible, the fishback strained detection device of staircase of the present invention can accurately detect fishback 100 stress size, when step 101 persistently gives fishback 100 loading force until fishback 100 stress reaches the ultimate value of trouble free service under the drive of external equipment, the yielding of fishback 100 rearward movement triggers electricity secured electrical and triggers switch, and secured electrical triggering switch sends signal and realizes stopping ladder.Thus the limit stress value of fishback 100 can be accurately known by the reading of strain gauge 3, thus accurately judge the flexibility ratio of fishback 100, if finding that flexibility ratio is not enough, staircase is adjusted.This invention ensures that the reliability of detection.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
