Cover-plate type prevents car cabin to lean forward device
Technical field
The utility model relates to the high-rise rescue elevator machine of a kind of non-twined formula, is that the high-rise rescue elevator machine of non-wound form prevents car cabin to lean forward device when car cabin is shifted out specifically.
Background technology
CN 202687670 U discloses the car cabin shift-out mechanism of the high-rise rescue elevator machine of non-twined formula, specifically (see CN 202687670 U Fig. 1-2): be car cabin framework 2 and car cabin 3, two, left and right above pedestal 1, a car 5 is set in each car cabin, establish hatch 6 below car cabin, become the gangway of car; It is vertical with left and right directions that car bilge portion arranges three, left, center, right longitudinal rail 7(), be rigidly connected between all longitudinal rails, at the upper surface of pedestal, the longitudinal assembly pulley 8 corresponding with guide rail is set, namely a longitudinal rail is placed on the longitudinal assembly pulley of row, makes whole car cabin become portable car cabin; See Fig. 3-4, the input shaft of the rotating shaft 10 key connecting handle reductor 11 of handle 9, the output axle key of handle reductor connects the axle of the first sprocket wheel 12, handle, handle reductor and the first sprocket wheel are installed on handle frame 13, the left sprocket wheel 14 of each installation one and right sprocket wheel 15 is located about handle frame front end, handle frame is arranged on pedestal, and left and right sprocket wheel is identical, and is less than the first sprocket wheel; Walking chain 17 front-end and back-end be fixed in intermediate rail, walking chain interlude successively with left sprocket wheel, the first sprocket wheel and right sprocket engagement; Pedestal is fixed on the flat edge of table of building top layer.Portable car cabin is placed on pedestal at ordinary times.When needing rescue, crank handle, first chain wheel drive walking chain outwards (left) walking, guide rail is outwards walked at assembly pulley thereupon, and portable car cabin is outwards moved to two hatch and leans out building edge completely, prepares for putting down car.Rescue terminates, and reverse jiggle bar, portable car cabin moves on pedestal inwards.
The car of said mechanism and hatch are located at before car cabin, before namely the weight in whole car cabin all concentrates on.When portable car cabin be outwards moved to two hatch lean out building edge completely time, front portion, car cabin is unsettled, if now without counterweight, can lean forward in car cabin, and whole car cabin can overturn forward.For preventing upset, ballasting stone need be loaded onto respectively at the rear portion in two car cabins, front and back counterweight.And the load that ballasting stone can increase whole device is set.
Summary of the invention
In order to reduce load, the purpose of this utility model cancels ballasting stone, provides the board-like car cabin that prevents of the high-rise rescue elevator cover of a kind of non-twined formula to lean forward device.
The purpose of this utility model is achieved in that it comprises the left and right guide rail of frame-type pedestal, car cabin and bottom thereof, it is characterized in that: fix the projection that several are arranged along guide rail in the outside of left and right guide rail; Inverted L shape material is fixed in the every side of the left and right side of pedestal, the direction that every side inverted L shape material is arranged is the upper end that its horizontal plate is positioned at vertical plate, and horizontal plate covers on the projection that this side is all, becomes the cover plate of projection, vertical plate is fixed on the pedestal of this side, and the inverted L shape material plate of both sides is arranged symmetrically.
When portable car cabin be outwards moved to two hatch lean out building edge completely time, front portion, car cabin is unsettled, under the anterior Action of Gravity Field in car cabin, lean forward in car cabin, the rear portion of rear portion, car cabin and guide rail can tilt, at this moment all projections are pushed down by cover plate above, prevent the rear portion of guide rail from tilting.
Compared with prior art, good effect of the present utility model is: cancel ballasting stone, alleviate the load of whole device.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram that the high-rise rescue elevator machine of non-wound form (omits car cabin) when car cabin and guide rail thereof shift out.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Detailed description of the invention
It comprises the left and right guide rail 2 in frame-type pedestal 1, car bilge portion 5, all fixes the projection that several are arranged along guide rail in the side, innner and outer of left and right guide rail, and for reducing friction, said projection is bearing 3, and the axle of bearing 3 is arranged on guide rail, on a left side for pedestal, inverted L shape material 4 is fixed in every side, right side, for alleviating the weight of inverted L shape material, said inverted L shape material is that several rectangular steel plates 41 are fixed on the vertical panel 422 of angle steel 42 with identical spacing, fixing mode is that the upper end of each rectangular steel plates is fixed by bolts on the vertical panel 422 of angle steel 42, inverted L shape material vertical plate lower edge is made to form continuous print machicolated form, the part protruded is the lower end of rectangular steel plates, the lower end of all rectangular steel plates is fixed on the pedestal of this side, said horizontal plate is the horizontal plate 421 of angle steel, horizontal plate covers on all bearings 3, become the cover plate (i.e. horizontal plate 421) of bearing, two inverted L shape material plates are arranged symmetrically.Because also securing several bearings in the inboard of left and right guide rail, therefore in the bearing side of guide rail inboard, there are also installed identical inverted L shape material.
When portable car cabin be outwards moved to two hatch lean out building edge completely time, front portion, car cabin unsettled (as Fig. 1), under the anterior Action of Gravity Field in car cabin, lean forward in car cabin, the rear portion of rear portion, car cabin and guide rail can tilt, at this moment all bearings are pushed down by the horizontal plate of angle steel above and cover plate, prevent the rear portion of guide rail from tilting.
