Abstract

The utility model relates to a non-alignment beam structure of a machine-room-less lift. The non-alignment beam structure comprises a lift underbeam, a lift car, guide rails and two diversion sheaves, wherein the lift underbeam is fixedly arranged at the bottom of the lift car, the guide rails are arranged on hoistway side walls positioned at two sides of the lift car, the lift underbeam is horizontally arranged on the lift car, the two sheaves are respectively and symmetrically hinged on the lift underbeam, the center line of the two sheaves is superposed with the central line in the front and back directions of the lift car, and the guide rails are arranged in two ends of the lift underbeam at one side of the central line in the front and back directions of the lift car in an offset mode. According to the technical scheme of the utility model, the offset distance between the central line of the guide rails in the front and back directions of the lift car and the central line of the lift car can be effectively reduced, so that the guide rails are closer to the central line of the lift car, the basic design requirement of the machine-room-less lift is met, the abrasion of the guide rails is greatly reduced, the performance of the machine-room-less lift is closer to that of a lift with a machine room, the structure is simple, material consumption is less, and the manufacturing cost is low.

Description

Machine room craspedodrome elevator is non-to center sill structure

Technical field

The utility model relates to the craspedodrome lift appliance, particularly relates to a kind of machine room craspedodrome elevator non-to center sill structure.

Background technology

In the prior art, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the rope sheave structure of machine-roomless lift mostly is greatly lower diversion sheave structure, because diversion sheave is positioned under car, and steel rope is directed to the both sides of car, so the guide rail of machine-roomless lift can only be biasing setting.

As shown in Figure 5, placement elevational schematic view for machine room diversion sheave in prior art and elevator underbeam, diversion sheave device and elevator underbeam are placed side by side, and the center line of rope sheave is positioned at the midline position of car substantially, and there is certain offset or dish in the center line of guide rail and rope sheave.

that center line with car coincides for the guide rail that machine room craspedodrome elevator is arranged, because the rope sheave that machine room is arranged is positioned at car top, do not take guide rail position, the more complicated of machine room and the rope sheave structure of machine room is compared, rope sheave takies the guide rail position of original machine room, it is far away that thereby the guide rail that causes machine-roomless lift departs from the car center line, and the machine room elevator car of comparing to the wearing and tearing of guide rail due to relatively large and serious many of the deviation of center of gravity, when the situation of safety tongs locking occurring, to the damage of guide rail and safety tongs than serious many of the elevator structure that machine room is arranged.

The utility model content

In view of this, the technical problems to be solved in the utility model is to provide a kind of machine room craspedodrome elevator non-to center sill structure, pass through the technical program, under the machine room condition, make the center of car in the craspedodrome elevator and rope sheave as far as possible close with guideway centreline, reduce wearing and tearing to reach, improve the purpose in service life.

for solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of machine room craspedodrome elevator is non-to center sill structure, include the elevator underbeam, car, guide rail and diversion sheave, described elevator underbeam is fixed on bottom car, described guide rail is arranged on the hoistway wall that is positioned at the car both sides, described elevator underbeam transverse horizontal is arranged on car, two rope sheaves symmetry respectively are hinged on the elevator underbeam, the rope sheave center line of two rope sheaves and the line of centers of car fore-and-aft direction coincide, guide rail biasing is arranged in the two ends of elevator underbeam of line of centers one side of car fore-and-aft direction.

The technique effect that the utility model reaches is as follows: machine room craspedodrome elevator is non-to center sill structure, pass through the technical program, can actv. have reduced the offset or dish at car fore-and-aft direction upper rail line of centers and car axis, make guide rail more near the center line of car, satisfied the prime design requirement of machine-roomless lift, reduced greatly the wearing and tearing of guide rail, the performance that makes machine-roomless lift approaches more machine room elevator, simple in structure, material consumption is few, and cost of manufacture is low.

Description of drawings

Fig. 1 is the rope sheave structural representation of machine room craspedodrome elevator in prior art.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is the non-constructional drawing to central sill of the utility model.

Fig. 4 is the lateral plan of Fig. 3.

Fig. 5 is upward view of the present utility model.

In figure, the line of centers of 1 rope sheave, 2 cars, 3 steel ropes, 4 guide rails, 5 elevator underbeams, 6 rope sheave center lines, 7 wheel shafts, 8 car fore-and-aft directions.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

as shown in Figure 3-Figure 5, the machine room craspedodrome elevator that the utility model relates to is non-to center sill structure, include elevator underbeam 5, car 2, guide rail 4 and rope sheave 1, described elevator underbeam 5 is fixed on car 2 bottoms, described guide rail 4 is arranged on the hoistway wall that is positioned at car 2 both sides, described elevator underbeam 5 transverse horizontal are arranged on car 2, two rope sheaves 1 symmetry respectively are hinged on elevator underbeam 5, the rope sheave center line 6 of two rope sheaves 1 coincides with the line of centers 8 of car fore-and-aft direction, guide rail 4 biasing is arranged in the two ends of elevator underbeam 5 of line of centers 8 one sides of car fore-and-aft direction.

The utility model is at identical wheels, under the prerequisite of identical car 2, adopt the technical program, the offset or dish of guide rail 4 and rope sheave center line 6 is far smaller than in prior art both offset or dishs, make the line of centers 8 of the more close car fore-and-aft direction of guide rail 4, the performance that makes machine-roomless lift approaches more machine room.

The above is only preferred embodiment of the present utility model, is not be used to limiting protection domain of the present utility model.
