Abstract
The utility model discloses an escalator and pedestrian host static load testing device which comprises a testing support, a direction control bolt, a loading mechanism, a torque rod and a load measuring instrument. The device is based on the principle of torque balance of a lever. The loading mechanism continues to increase force applied on a tested host through the torque rod, thus the tested host is completely destroyed. The maximum load of the tested host is tested. The role of the direction control bolt is to maintain that the loading mechanism and the torque rod are in the vertical state. The load measuring instrument is located between the loading mechanism and the torque rod to read the pulling force of the applied load. According to the utility model, the simulation test of an escalator or an automatic pedestrian is realized in a small spatial range; the structure is compact, and the operation is easy; the insecurity of an escalator or automatic pedestrian load test is avoided; and the accuracy of an experimental result is high.

Background technology
At present, there is no the method for testing of standard for escalator or automatic pedestrian path, generally all adopt directly and to execute loaded method at escalator or automatic pedestrian path and realize test, the method is because system is huge especially, experimental period is long, and the result is not accurate enough.Therefore, industry wishes to occur a kind of simple and easy method and device of testing escalator or automatic pedestrian path always, can be in little space the short time measure exactly the nominal load of escalator or automatic pedestrian path.
The utility model content
The technical problems to be solved in the utility model provides escalator and the pavement main frame static load proving installation that a kind of measuring period is short, precision is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of escalator and pavement main frame static load proving installation is characterized in that a test bracing frame; One load maintainer, this load maintainer are installed on the test bracing frame; One load measure instrument, an end of this load measure instrument is connected with load maintainer; One torsion bar, an end of this torsion bar can be fixedly connected with tested main frame rotating shaft, the other end and the hinge joint of load measure instrument, the load that load maintainer applies is transferred to tested main frame rotating shaft by torsion bar.
Further, comprise that also one is installed in the direction control bolt of test on the bracing frame, an end of described direction control bolt is equipped with the first setting nut, is connected between the other end and load maintainer and the load measure instrument.
Further, pass through spline joint between described torsion bar and the tested main frame rotating shaft.
Further, described load measure instrument is a pulling force sensor.
Further, described load maintainer is the loading screw rod that is installed on the test bracing frame, on this loading screw rod the second setting nut is installed.
The beneficial effects of the utility model: the static load measurement mechanism is according to the principle of moment balance of lever, whole device is compressed within the test bracing frame, thereby in little spatial dimension, realized the load simulation test of escalator or automatic pedestrian path, compact conformation, easy operating, avoid adopting the insecurity of escalator or automatic pedestrian path load testing, the experimental result accuracy is high.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Embodiment
A kind of escalator shown in Figure 1 and pavement main frame static load proving installation comprise a test bracing frame 1, a load maintainer 2, a load measure instrument 3, a torsion bar 4.
This load maintainer 2 is for being installed in the loading screw rod on the test bracing frame 1, the second setting nut 8 is installed on this loading screw rod, one end of load measure instrument 3 is connected with load maintainer 2, one end of torsion bar 4 can be fixedly connected with tested main frame 5 rotating shafts, the other end and 3 hinge joints of load measure instrument, at test bracing frame 1 direction control bolt 6 is installed, one end of this direction control bolt 6 is equipped with the first setting nut 7, regulating direction control bolt 6 by the first setting nut 7 makes loading screw rod and torsion bar 4 keep plumbnesss, load measure instrument 3 can not need to consider the variation of angle again and directly read the loading moment value, be connected between direction control bolt 6 other ends and load maintainer 2 and the load measure instrument 3, this load measure instrument 3 is a pulling force sensor.
Connected mode is spline joint between described torsion bar 4 and 5 rotating shafts of tested main frame, spline joint is comprised of a plurality of key pins and the keyway on rotating shaft and the wheel bore, the key pin side is workplace, extruding by the key pin side comes transmitting torque, after in application of force process, destroying certain key pin, only need swiveling wheel hub bore respective angles again with the rotating shaft spline joint, just can continue application of force destruction, this process that circulates is until destroy fully, and tested main frame 5 places on the test bracing frame 1.
Fig. 2 is final assembly figure of the present utility model, load measure instrument 3 one ends are connected in a bit with the loading screw rod, this tie point is connected with direction control bolt 6 again, load measure instrument 3 other ends and the hinge joint of torsion bar 4 one ends, the rotating shaft of torsion bar 4 other ends and tested main frame 5 is integrated by the spline joint embedding.
The course of work of the present utility model is, be rotated in the forward the second setting nut 8 that loads screw rod, load screw rod and apply the pulling force that increases gradually by torsion bar 4 rotating shafts to tested main frame 5, meanwhile, it is vertical with torsion bar 4 that the first setting nut 7 of adjusting direction control bolt 6 keeps loading screw rod, apply the maximum load critical value that can bear above tested main frame 5 until load screw rod, the rotating shaft of tested main frame 5 destroys fully, this moment, tested main frame 5 reached maximum load, according to the principle of moment balance of lever
,This moment, the reading of pulling force sensor namely was the maximum load of tested main frame 5.
The static load measurement mechanism is based on the principle of moment balance of lever, whole device is compressed within the test bracing frame 1, thereby in little spatial dimension, realized the simulation test of escalator or automatic pedestrian path, compact conformation, easy operating, avoid adopting the insecurity of escalator or automatic pedestrian path load testing, the experimental result accuracy is high.
The above only is preferential embodiment of the present utility model; the utility model is not limited to above-mentioned embodiment; load measure instrument 3 comprises that also pointer shows the tension measurement instruments such as tautness meter, digital display electronic pull and push dynamometer; load maintainer 2 also comprises the force application mechanisms such as drive motor, lifting jack charger; in a word, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
