The applying date is that the patent document that July 30, notification number in 2015 are CN204751765U discloses under a kind of elevator Mechanical stopping device, including the connecting plate erected and the stop part that can be rotated around trunnion axis, connecting plate has opening, is overhauling When stop part is turned to the opening of connecting plate, stop part is holded up into placement after the completion of maintenance.Although this is apparatus simplified Structure, but its stop part is at work, and the part contacted with cage bottom is cantilevered support structure, and there are biggish press-bendings even The risk of fracture, structure are unreliable.
Summary of the invention
In order to overcome the drawbacks of the prior art, the object of the present invention is to provide a kind of safe and reliable, simple elevators of structure Lower mechanical preventing device.
In order to achieve the goal above, the technical solution of lower mechanical preventing device of elevator of the present invention is:
Lower mechanical preventing device of elevator includes the support column being vertically arranged, and is connected with rotating arm on support column, rotating arm it is separate One end of support column is connected with hinge, the shaft that there is hinge axis to extend along the vertical direction, in use, support column can rotate Axis rotation, support column have the working position below carriage and the inoperative position except carriage planimetric area.
Hinge is fixed on cage guide by mounting plate.
The first lock for support column to be fixed on to working position and inoperative position respectively is equipped between mounting plate and rotating arm Determine structure and the second locking structure.
Mounting plate is equipped with the overhanging plate perpendicular to mounting plate, and overhanging plate and hinge are located at the tow sides of mounting plate, hangs It stretches and offers first positioning hole and second location hole on plate, the end of rotating arm is equipped with the positioning plate for being parallel to overhanging plate, positioning Plate is equipped with aperture, and when support column is located at working position, first positioning hole alignment apertures are locked using positioning bolt, formation the One locking structure, when support column is located at inoperative position, second location hole alignment apertures are locked using positioning bolt, form the Two locking structures.
It is equipped with the verifying for detecting support column working condition between mounting plate and rotating arm to switch, when support column is in non-work When making position, the end triggering verifying switch of rotating arm, elevator could be operated normally.
Mounting plate is mounted on the back side of car guide rail by pressure plate structure, when support column is at inoperative position, rotating arm with Mounting plate is parallel, and when support column is in working position, rotating arm is vertical with mounting plate.
The top of support column is equipped with yielding rubber.
Support column and adjutage are made of square tube.
Due to the implementation of above technical scheme, the present invention has the following technical effect that in the present invention compared with prior art, Support column can be rotated around the shaft of vertical direction, be transferred to and produce carriage vertical plane, thus switch operating and inoperative State has simplified structure, and in working position, support column is in below carriage, and when carriage surprisingly falls, cage bottom is pressed in vertical On support column, structure is safe and reliable, mechanically prevents the further whereabouts of carriage, provides for pit operating personnel enough Safe space avoids squeezing injury;Support column turns to inoperative position, is located at except carriage planimetric area, The normal operation of elevator is not influenced.
Detailed description of the invention
Fig. 1 is schematic diagram when the present invention is in inoperative position in elevator device;
Fig. 2 is schematic diagram when the present invention is in working position in elevator device;
Fig. 3 is the structural schematic diagram of lower mechanical preventing device of elevator in Fig. 1;
Fig. 4 is the schematic diagram of another angle of Fig. 3;
Fig. 5 is the structural schematic diagram of lower mechanical preventing device of elevator in Fig. 2;
Fig. 6 is the schematic diagram of another angle of Fig. 5.
Specific embodiment
The technical scheme of the invention is described in detail through specific implementation examples.
As shown in Figures 1 to 6, lower mechanical preventing device of elevator includes the support column 1 being vertically arranged, connects on support column 1 Rotating arm 2,2 one end of rotating arm hinge 3, hinge 3 has the shaft 30 that extends along the vertical direction of axis, in use, hinge 3 is solid It is scheduled on mounting plate 4, support column 1 30 can rotate around the shaft, and support column 1 has the working position for being in 9 lower section of carriage and is located at Inoperative position except 9 planimetric area of carriage.It is fixed with vertical overhanging plate 5 on mounting plate 4, overhanging plate 5 and 3, hinge In the tow sides of mounting plate 4.First positioning hole 51 and second location hole 52 are offered on overhanging plate 5, the end of rotating arm 2 is set It is parallel to the positioning plate 21 of overhanging plate, positioning plate 21 is equipped with aperture.When support column is located at working position, first positioning hole 51 Alignment apertures are locked using positioning bolt 6, form the first locking structure, support column is locked in working position;When support column is located at When inoperative position, 52 alignment apertures of second location hole are locked using positioning bolt 6, form the second locking structure, support column is locked It is fixed.The verifying switch 7 for detecting support column working condition is equipped between mounting plate and rotating arm, when support column is in inoperative position When, the end triggering verifying switch 7 of rotating arm, elevator could operate normally, and guarantee that support column is located at carriage planimetric area Except, elevator normal operation is not influenced.If support column drives rotating arm to go in carriage planimetric area, elevator stops fortune Row, i.e., support column is in carriage lower part, when carriage surprisingly falls, cage bottom pressure on the support columns, the mechanical resistance of support column The only further whereabouts of carriage provides enough safe spaces for pit operating personnel, avoids squeezing injury.This In embodiment, mounting plate 4 is mounted on the back side of car guide rail 8 by pressure plate structure.When support column is at inoperative position, rotating arm It is parallel with mounting plate, when direction is rotated by 90 ° support column into carriage upright projection, go to working position, rotating arm and mounting plate Vertically.The top of support column is equipped with yielding rubber, and support column and adjutage are made of square tube.
In other embodiments, hinge can be fixed in pit.
In other embodiments, the first locking structure and the second locking structure can also use the locking structure of male-female engagement Or other conventional locking structures.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features; And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and Range.
