Abstract

The invention discloses an elevator car frame, which comprises a pair of left and left vertical beam, an upper beam horizontally arranged between the pair of vertical beams and two rope wheel components, wherein the rope wheels of the rope wheel components are arranged on the outer side of the upper beam at intervals along the length direction of the upper beam; the connecting line of the centers of the rope wheels of the two rope wheel components and the axes of the rope wheels of the two rope wheel components are vertical and horizontal, and the distance between the two rope wheel components is not limited by car guide shoes fixed on the two end faces of the upper beam, so the wrap angles of the elevator are enlarged, the application range of the elevator is enlarged, the bottom parts of the rope wheels of the rope wheel components are lower than the lower surface of the upper beam, the upper parts of the rope wheels of the rope wheel components are higher than the upper surface of the upper beam; and thus, the rope wheel components and the upper beam are superposed on a vertical projection plane, so the requirements of the elevator on the height of the top layer of a shaft are lowered and the building cost is saved.

Description

A kind of elevator car frame

Technical field

The present invention relates to a kind of elevator car frame.

Background technology

On elevator, existing rope sheave is arranged in the structure of sedan-chair frame upper beam, in the time of in the middle of rope sheave is arranged in sedan-chair frame upper beam, promptly put the beams in place and comprise two upper beam sheets, two rope sheaves are when the length direction of upper beam sheet is arranged between two upper beam sheets separately, because being respectively arranged with car on the two ends of two upper beam sheets leads boots and leads the boots permanent seat, then be subjected to car to lead boots and lead the restriction of boots permanent seat, spacing between two rope sheaves can not be too big, thereby make the counterweight center bigger, and then influence the cornerite of elevator wire rope on traction sheave to the distance of rope sheave; When rope sheave is arranged in the tie-beam of putting the beams in place perpendicular with the sedan-chair frame, tie-beam generally has two, two tie-beams parallel on the upper surface or lower surface that is disposed on upper beam, between the relative end rope sheave assembly is installed on two tie-beams, the rope sheave assembly be in upper beam above or below, it is less that rope sheave assembly and upper beam do not overlap on vertical plane or overlap, the height of elevator car frame upper beam structure is higher like this, cause elevator that the headroom height of hoistway is had relatively high expectations, thereby increased the cost of building.

Summary of the invention

Thereby the purpose of this invention is to provide a kind of rope sheave assembly and reduce the elevator car frame of elevator hoistways headroom height with putting the beams in place on vertical plane, to coincide, and the car that the distance on this elevator car frame between two rope sheave assemblies is not fixed on the upper beam is led the restriction of boots and permanent seat, thereby can increase the cornerite of elevator.

For achieving the above object, the technical solution used in the present invention is: a kind of elevator car frame, comprise the upright beam that is provided with about a pair of, be horizontally set on the upper beam between a pair of described upright beam, two rope sheave assemblies, the rope sheave of described two rope sheave assemblies is arranged on the outside of described upper beam separately along the length direction of described upper beam, the rope sheave line of centres of described two rope sheave assemblies, the rope sheave axial line of described rope sheave assembly is horizontally disposed with perpendicularly, the rope sheave bottom of each described rope sheave assembly is lower than the lower surface of described upper beam, and the rope sheave top of each described rope sheave assembly is higher than the upper surface of described upper beam.

As a kind of concrete embodiment, described upper beam comprises two upper beam sheets, described two upper beam sheets are separately positioned on described upright beam front and back side, offer mounting hole on the outside, front and back of described two upper beam sheets, the sheave shaft of described rope sheave assembly is contained in the mounting hole of described two upper beam sheets, and the rope sheave of described rope sheave assembly is exposed at the preceding outside or the outside, back of described two upper beam sheets.

Because the utilization of technique scheme, the present invention compared with prior art has following advantage: the rope sheave of two rope sheave assemblies is in the outside of upper beam, then the car that is not fixed on above the upper beam two ends of the distance between two rope sheave assemblies is led the restriction of boots, thereby can increase the cornerite of elevator, the Applicable scope of elevator is enlarged; The rope sheave bottom of each rope sheave assembly is lower than the lower surface of upper beam, the rope sheave top of each rope sheave assembly is higher than the upper surface of upper beam, rope sheave assembly and upper beam coincide on vertical plane like this, thereby can reduce the requirement of elevator to the hoistway headroom height, to save the cost of building.

Description of drawings

The specific embodiment

Further set forth structure of the present invention below in conjunction with accompanying drawing.

Shown in Fig. 1-3, a kind of elevator car frame, comprise the upright beam 3 that is provided with about a pair of, be horizontally set on the upper beam 2 between the opposition beam 3, two rope sheave assemblies 5, the rope sheave of two rope sheave assemblies 5 is arranged on the outside of upper beam 2 separately along the length direction of upper beam 2, the rope sheave line of centres of two rope sheave assemblies 5, the rope sheave axial line of rope sheave assembly 5 is horizontally disposed with perpendicularly, the rope sheave of two rope sheave assemblies 5 is in the outside of upper beam 2, then the car that is not fixed on above the upper beam two ends of the distance between two rope sheave assemblies 5 is led the restriction of boots 1, thereby can increase the cornerite of elevator, the Applicable scope of elevator is enlarged, the rope sheave of rope sheave assembly 5 is in the outside of upper beam 2, and the installation of rope sheave is convenient in the cantilevered setting of rope sheave, repair and maintenance and replacing.The rope sheave bottom of each rope sheave assembly 5 is lower than the lower surface of upper beam 2, the rope sheave top of each rope sheave assembly 5 is higher than the upper surface of upper beam 2, rope sheave assembly 5 and upper beam 2 coincide on vertical plane like this, thereby can reduce the requirement of elevator to the hoistway headroom height, to save the cost of building.

In Fig. 2 and Fig. 3, upper beam 2 comprises two upper beam sheets 21, two upper beam sheets 21 are separately positioned on upright beam 3 front and back sides, offer mounting hole on the outside, front and back of two upper beam sheets 21, the sheave shaft of rope sheave assembly 5 is contained in the mounting hole of two upper beam sheets 21, and the rope sheave of rope sheave assembly 5 is exposed at the preceding outside or the outside, back of two upper beam sheets 21.Be provided with permanent seat above two upper beam sheet 21 corresponding ends, car be housed on this permanent seat lead boots 1, car is led boots 1 and is matched with car guide rail 6, and the guiding car carries out dipping and heaving along guide rail.

To sum up, be arranged on the outside of upper beam by rope sheave with the rope sheave assembly, the car that makes distance between two rope sheave assemblies be not fixed on above the upper beam two ends is led the restriction of boots, and, the rope sheave of rope sheave assembly and upper beam coincide on vertical plane, thereby can reduce the requirement of elevator to the hoistway headroom height.
