Abstract
The utility model provides a lift car frame for an elevator, and belongs to the technical field of elevators. The lift car frame for the elevator comprises a framework formed by an upper beam, an underbeam and two vertical beams, and two bistable switches, wherein a notch for installation of the upper beam is formed in the top end of each vertical beam, the upper beam is arranged in an inverted mode, notch ends of the upper beam are upward, the two bistable switches are installed on the vertical beams through a support of the upper beam and are close to the upper beam end, and reinforcing plates connected with a lift car are respectively installed on positions, close to the two vertical beam ends, of the lower beam. Through the two arranged bistable switches and bending structures matched with the bistable switches and arranged at top ends of the vertical beams, a limit buffer is formed, space occupying a well and installation time are saved. The lift car frame for the elevator improves security of maintainers in maintenance of the elevator.

Car frame is the carrying structure of car, and the load of car is delivered to traction steel-cable by it.When safety tongs action cushion at collision, also will bear consequent antagonistic force, so car frame to there be enough intensity.In the existing elevator structure, the structure of car frame is had relatively high expectations to headroom height and pit depth.
Elevator safety gear is under the manipulation of velocity limiter, when elevator speed surpasses the limited speed that velocity limiter is set, or takes place under fracture and the lax situation at suspension strop, with the urgent stop of car and be clamped in a kind of safety device on the guide rail.He provides the actv. protective effect to the safe operation of elevator, generally it is installed on car frame or the counterweight frame.And it is bigger that existing safety tongs shift mechanism takies pit depth.
Summary of the invention
At the technical matters of above-mentioned existence, the invention provides a kind of car frame, saved the space and the set-up time that take hoistway.
The objective of the invention is to be achieved through the following technical solutions:
A kind of elevator car frame, comprise framework and two bistable switches that upper beam, underbeam and two upright beams constitute, described upright back end has installs the notch of putting the beams in place, upper beam notch end upwards, two bistable switches are installed in close last beam-ends on the upright beam by its support, are separately installed with the brace panel that connects car near two upright beam-ends on the underbeam.
Further, also be provided with the safety tongs shift mechanism near described underbeam place, comprise that axle sleeve, crank, connecting rod, safety tongs that rotating shaft and rotating shaft two ends symmetry connects lift plate, described crank end is connected with safety tongs by connecting rod respectively and lifts plate, has the fixedly through hole of rope at crank.
Further, described rotating shaft and shaft room also are provided with baffle plate.
Further, on the diversion sheave of described underbeam bottom installation protective cover is installed.
Further, described upright back end has the bending structure that cooperates with limit switch, forms the limit and hits bow.
Further, described upper beam is provided with the correcting member of regulating the diagonal line error near the Li Liang two ends, and described correcting member is L shaped gusset.
Beneficial effect of the present invention:
1. two bistable switches of the present invention by arranging, and upright back end have the bending structure that cooperates with limit switch, form the limit and hit bow, have saved the space and the set-up time that take hoistway.
2. adopt safety tongs shift mechanism of the present invention to promote safety tongs, simple in structure, it is convenient to promote.
3. on the diversion sheave of the present invention protective cover is installed, has improved the safety of service personnel when safeguarding elevator.The correcting member that described upper beam arranges near the Li Liang two ends, the diagonal line error that is used for regulating car frame.

The specific embodiment
Specifically describe the present invention below in conjunction with drawings and Examples.
Embodiment: as shown in Figure 1-Figure 3, the present invention includes framework and two bistable switches 9 that upper beam 2, underbeam 4 and two upright beams 3 constitute, described upright beam 3 tops have the notch that upper beam 2 is installed, upper beam 2 is existing structure, the cross section is similar to the " structure, and 2 inversions of putting the beams in place are installed, and its notch end upwards, two bistable switches 9 are installed in close 2 ends of putting the beams in place on the upright beam 3 by its support, are separately installed with the brace panel 6 that connects car near two upright beam 3 ends on the underbeam 4.
As Fig. 4-shown in Figure 6, also be provided with the safety tongs shift mechanism near described underbeam place, comprise: rotating shaft 83, baffle plate 82, axle sleeve 86, first crank 81, second crank 88, connecting rod 84, described rotating shaft 83 two ends are passed baffle plate 82 respectively and are symmetrically connected with axle sleeve 86, two axle sleeves 86 connect first crank 81 and second crank 88 respectively, two crank ends are connected with safety tongs by connecting rod 84 respectively and lift plate 85, have the fixedly through hole 87 of rope at first crank 81.Through hole 87 places are the speed limiter wire rope mounting hole, when the descending hypervelocity of car, the velocity limiter action, speed limiter wire rope drives first crank, 81 upward movements, and first crank 81 fixedly becomes one with connecting rod 84, and connecting rod 84 lifts plate 85 with safety tongs and fixes, safety tongs lifts plate 85 upwards after the action, the steel ball that drives in the safety tongs upwards moves along its path of motion, fits tightly with guide rail, makes lift car not in downward operation.
On the diversion sheave 7 that install described underbeam 4 bottoms protective cover 5 is installed, guarantees the safety of service personnel when at the bottom of the sedan-chair repair and maintenance being installed, when steel rope is loosening, prevent that steel rope from taking off groove.
As shown in Figure 2, described upright beam 3 tops have the bending structure that cooperates with the car frame limit switch, form the limit and hit bow 10, and its effect is: when same parts are realized the elevator operation flat bed, more stop ladder during layer, saved the step of installing.
Described upper beam 2 is provided with the correcting member 1 of regulating the diagonal line error near upright beam 3 two ends, this correcting member is L shape gusset, and is integrally welded with upper beam 2, installs with upright beam 3, become 90 degree right angles after guaranteeing upper beam 2 and upright beam 3 being installed, the diagonal line error of whole sedan-chair frame is little.Brace panel 6 is welded on the Li Liang lower end, when being connected with car, prevents that car from tilting forward and back.
