Fig. 3 is foot platform overall structure schematic diagram of the present invention.
The implication of Reference numeral in figure:

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Shown in Fig. 1, a kind of inspection platform of the present invention, comprises four expansion links 1, cross bar 2 and foot platform 3; Expansion link 1 forms by being no less than two joint expansion couplings, and expansion coupling sidewall is provided with screw hole, is provided with lock-screw in screw hole; The expansion coupling of the least significant end of four expansion links 1 connects successively by four cross bars 2, and the expansion coupling of the most significant end of four expansion links 1 connects successively by four cross bars 2; Between the expansion coupling of the corresponding height of at least one group of adjacent expansion bar 1, connect cross bar 2; Foot platform 3 is arranged on the expansion coupling of most significant end of four expansion links 1, foot platform 3 comprises a flat board being square 4, side plate frame 5, foot 6, stiffener 7, one side of side plate frame 5 is fixedly connected with dull and stereotyped 4, the opposite side bending of side plate frame 5 is hook part 9, between side plate frame 5 and dull and stereotyped 4, form a storage tank 8, foot 6 is arranged on dull and stereotyped 4 four jiaos, foot 6 is fixedly connected with side plate frame 5 with dull and stereotyped 4, expansion coupling is arranged in foot 6, stiffener 7 is arranged in storage tank 8, and stiffener 7 two ends are fixedly connected with side plate frame 5.In the present invention, first be provided with side plate frame 5, side plate frame 5 is fixedly connected with dull and stereotyped 4, as shown in Figures 2 and 3, strengthened the intensity of dull and stereotyped 4 surroundings, because foot 6 is fixedly connected with side plate frame 5 with dull and stereotyped 4, between foot 6 and flat board 4 and side plate frame 5, all by welding, interfixed, so just avoid 6 of foots in prior art to be connected with dull and stereotyped 4, thereby caused dull and stereotyped 4 to bear the excessive drawback of pressure with foot 6 junctions.Side plate frame 5 and dull and stereotyped 4 bears the pressure being conducted by human body jointly, and by pressure conduction to expansion coupling.In addition, stiffener 7 of the present invention, can strengthen the pressure tolerance at dull and stereotyped 4 middle parts.As shown in Figure 2, stiffener 7 two ends are fixedly connected with side plate frame 5 by screw.
As shown in Figure 3, stiffener 7 is strip, and flat board 4 comprises horizontal and vertical, and dull and stereotyped 4 lateral length is shorter than longitudinal length, and stiffener 7 is along longitudinal setting of flat board 4.Due under load-bearing state, dull and stereotyped 4 be longitudinally easy to because length is long to be produced than laterally larger deformation, after stiffener 7 is set, stiffener 7 provides the strength of dull and stereotyped 4 one carryings, thereby avoids dull and stereotyped 4 because excessively deformation and bending.In addition, in actual design, can be so that stiffener 7 lean mutually with dull and stereotyped 4, stiffener 7 leans mutually with hook part 9.Purpose of design makes stiffener 7 and dull and stereotyped 4 close contacts like this, stiffener 7 and hook part 9 close contacts, hook part 9 catches on stiffener 7, makes dull and stereotyped 4 pressure that bear can be transferred to stiffener 7 at once, and the pressure of stiffener 7 carryings also can be transferred to side plate frame 5.Like this, in fact flat board 4 pressure that are subject to can be shared by side plate frame 5 and stiffener 7.
Further, can on flat board 4 and side plate frame 5, equally distributed hole 10 be all set.Perforate can reduce the deadweight of flat board 4 and side plate frame 5 on the one hand, also can not cause the obvious decline of both intensity.
More than show and described basic principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
