Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
Elevator Stop supporting mechanism described in the utility model, as shown in Fig. 1,2 and 4 to 7, comprises the upper support bar 2 be installed on lift car 1, lower support bar 3, expansion link 4, also comprises the hoistway back-up block 12 be arranged on elevator hoistways 11 wall;
Described car 1 is installed with upper fixed block 6 and lower fixed block 7 near the lateral wall bottom of car door 14, upper fixed block 6 is provided with upper boom rotating shaft 8, lower fixed block 7 is provided with expansion link rotating shaft 9, and upper boom rotating shaft 8 position is higher than expansion link rotating shaft 9 position, upper boom rotating shaft 8 is less than expansion link rotating shaft 9 apart from car door 14 distance apart from car door 14 distance;
Described upper support bar 2 one end is articulated with in described upper boom rotating shaft 8, described expansion link 4 body of rod is articulated with in described expansion link rotating shaft 9, described upper support bar 2 the other end is hinged by limit rotary shaft 5 and described lower support bar 3 one end, is hinged in the middle part of described expansion link 4 retractable ends and described lower support bar 3;
On described hoistway 11 wall, the below of each layer elevator door 13 is equipped with the hoistway back-up block 12 of outstanding well enclosure, and described lower support bar 3 other end can be resisted against on described hoistway back-up block 12;
Described upper and lower strut bar 2,3 is greater than 180 degree towards the angle of expansion link 4;
In described Elevator Stop supporting mechanism, under each state of upper and lower strut bar 2,3, limit rotary shaft 5 position is all lower than expansion link rotating shaft 9 position.
During elevator runs, when needs rest in certain layer, this Elevator Stop supporting mechanism starts, by the elongation of expansion link 4, in drive, lower support bar 2, 3 actions, final lower support bar 3 bottom is resisted against on hoistway back-up block 12, on, lower support bar 2, 3 due to connect both jointed shaft be limit rotary shaft 5, in the constraint of this limit rotary shaft 5, lower support bar 2, 3 are greater than 180 degree towards the angle of expansion link 4, this kind of structure forms a kind of stable support, make this Elevator Stop supporting mechanism can bear a part of car weight, also mitigate expansion link 4 bearing pressuries simultaneously, add the durability of this Elevator Stop supporting mechanism, when elevator starts rising or declines, again by the contraction of expansion link 4, drive the action of upper and lower strut bar 2,3, finally make upper support bar 2, lower support bar 3, expansion link 4 all close within the scope of car 1 sidewall, and do not protrude from the outerplanar of car door 14, do not affect the normal work of elevator.
Fig. 4 to 7 in turn, show this Elevator Stop supporting mechanism when Elevator Stop state, lower support bar 3 bottom is resisted against on hoistway back-up block 12, during to elevator rising or decline state, upper support bar 2, lower support bar 3, expansion link 4 close within the scope of car 1 sidewall, and do not protrude from the change in location in the outerplanar whole process of car door 14.This Fig. 4 to 7 is reversible, on the contrary be elevator rise or decline state to this Elevator Stop supporting mechanism change in location schematic diagram during Elevator Stop state.
It should be noted that, upper support bar 2, lower support bar 3, expansion link 4 and the hoistway back-up block 12 be arranged on elevator hoistways 11 wall that above-mentioned car 1 is installed near the lateral wall bottom of car door 14 must support the use, as shown in Figure 2,3, only can be present in the side of car 1, also can the both sides of car 1 all install, the effect that both sides are all installed is better than side and installs.
Preferably, described in this Elevator Stop supporting mechanism, expansion link 4 is electric pushrod, selects the electric pushrod of suitable power according to the concrete technical index of elevator.Described expansion link 4 also can be the existing machinery parts that the cylinder, hydraulic actuating cylinder etc. meeting the concrete technical index of elevator has the body of rod and telescopic end structure.
Further, described lower support bar 3 the other end is installed with the supporting member 15 matched with hoistway back-up block 12.
Further, described lower fixed block 7 is fixed with the positioning plate 10 perpendicular to this side near the side of car door 14, when rising for elevator or decline, and upper support bar 2 retrieving position spacing.
Above section Example of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
