Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification sheets word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
As shown in figs. 1-7 be a kind of way of realization according to the segmentation contraction type protective cover for escalator machine room lower of the present utility model, comprising:
Support, its upper bracket 230 being divided into left and right to arrange in pairs, medium-height trestle 220 and lower bracket 210, as shown in Figure 4, on described, in, lower bracket is from top to bottom symmetrically distributed on the left and right round end side plate of escalator round end, that is on the both sides of round end side plate, a support is respectively provided with, formed a pair, every pair of brackets is equidistant to be disposed on described round end side plate, the step 300 of escalator completes revolution between paired support, each support vertical in round end side plate outside face and upwards extend, described upper bracket 230 upper end offers a through hole 231, as shown in Figure 6, secure shroud 110, it is the steel plate structure of circular arc, four of described secure shroud end angles be separately fixed at described in, lower bracket upper end, the built on stilts outside being arranged on escalator round end of secure shroud 110 is made with this, the arcuate directions of described secure shroud 110 is consistent with the arcuate directions of round end side plate, and the width of secure shroud 110 is not less than the width of step 300, slip guard shield 120, it is the circular arc steel plate structure identical with described secure shroud 110 arc radius, the right and left of described slip guard shield 120 is arranged to U-shaped guide rail 122 structure, it is movably set on the right and left of described secure shroud 110, because secure shroud 110 is consistent with the shape of slip guard shield 120, slip guard shield 120 freely can be shunk up and down in secure shroud 110, complete the moving process of protective cover, the both sides, upper end of described slip guard shield 120 are respectively arranged with a column magnet steel 121, it extends a segment distance to described round end side plate direction, when opening protective cover when slip guard shield 120 retracted downward, magnet steel 121 can laterally be supported in the upper end of secure shroud 110, avoid slip guard shield 120 landing downwards further, as Figure 1-3, maintainer can overhaul from the end of opening of protective cover escalator, all monoblock protective cover must be disassembled when avoiding keeping in repair at every turn, facilitate staff, improve work efficiency.The diameter of described magnet steel 121 is less than the internal diameter of described through hole 231, when slip guard shield 120 upwards closes, slip guard shield 120 upper end moves to upper bracket 230 place, now magnet steel 121 just in time aligned through holes 231, directly magnet steel 121 is passed through hole 231, slip guard shield 120 is made to be fastened on upper bracket 230, protective cover is closed again, as illustrated in figures 4-5, when needs are opened and are overhauled, slip guard shield one is carried backward, magnet steel 121 can be taken out from through hole 231, slip guard shield 120 gets final product retracted downward and opens protective cover, will as can be seen here, staff can open or close protective cover very easily and overhaul, the effect of safeguard work personnel personal safety can be played, there is the work capacity that can reduce a staff, raise the efficiency.
In another kind of embodiment, in technique scheme, described through hole 231 is long oval type through hole, aperture is greater than the diameter of magnet steel 121, convenient slip guard shield 120 upwards close put in place time, magnet steel 121 can aligned through holes 231 quickly and accurately, the time of the lift slip guard shield 120 that reduces a staff, further facilitates staff.
In another kind of embodiment, in technique scheme, described upper bracket 230 is made up of Q235 carbon steel, make after magnet steel 121 is inserted into through hole 231, this magnet steel 121 will hold upper bracket 230 firmly, thus make slip guard shield 120 be fixed on upper bracket 230, without nutting, as long as the words opening guard shield guard shield backward once having carried out, slip guard shield 120 landing downwards and open protective cover, under full open position, as Figure 1-3, because this cylindrical magnet steel 121 is just as individual hook, this slip guard shield 120 is made to catch on secure shroud 110 upper end, be unlikely to slip guard shield 120 and drop to the end always.And general design is all respectively have a bolt at guard shield top the right and left, bolt pierces in the hole of upper bracket, and nut of then screwing on is fixed.This programme can eliminate the trouble of nutting, increases work efficiency further.
In another kind of embodiment, in technique scheme, described support is bending component, as shown in Figure 6 be the structural representation of upper bracket 230, its bottom is vertically fixed on described round end side plate, bending certain distance in the upper end Vertical dimension of described support, makes the protective cover energy envelope firmly whole stair revolving end completely of support and disposed thereon.Described secure shroud 110 and described slip guard shield 120 cover the outside face being arranged on shown round end side plate jointly, described step 300 by envelope in described protective cover, the face area of described slip guard shield 120 is greater than step 300 maximum secting area of escalator, when slip guard shield 120 is opened, step 300 can take out by staff easily from protective cover, complete service work, convenient and practical.
In another kind of embodiment, in technique scheme, the length of the elongated end of described magnet steel 121 is slightly larger than the width of described U-shaped guide rail 122, ensure that magnet steel 121 can be supported in the upper end of secure shroud 110, Stable sliding guard shield 120, make it fall further, ensure that magnet steel 121 can pass through hole 231 simultaneously, slip guard shield 120 is fixed with upper bracket 230.Meanwhile, the both sides of slip guard shield 120 are provided with U-shaped guide rail 122 structure, the compressive strength of protective cover is strengthened further, improves the degree of protection of protective cover.
From the above mentioned, protective cover of the present utility model can complete whole maintenance process without the need to dismounting, convenient and practical; And protective cover can free-open-close, effectively for maintainer provides safety guard-safeguard, can improve again the work efficiency of maintainer; Simultaneously the slide both sides of guard shield are designed to U-shaped structure, and the compressive strength of guard shield can reach the requirement of protection personnel, improves the safety factor of protective cover, convenient and practical.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification sheets and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
