Problems solved by technology

However, the technical solution of this patent also has some disadvantages: (1) the guide rib of the pulley requires high processing precision and high material cost; (2) the thickness of the belt at the guide groove of the belt is thin, during operation, if the guide rib of the pulley It does not fit well with the guide groove of the belt, and one side is under too much pressure, which may cause the flat belt to break or greatly shorten its life
However, the disadvantages still existing in this patent are: the working surface of the rope wheel with the ribbed side of the suspension cable is cumbersome to process, the matching precision of the guide wheel matched with it is high, and the processing cost is high; the traction suspension cable and the guide wheel are poorly matched. , one side of the traction suspension cable is under too much pressure, which may cause belt breakage or greatly shorten the service life of the traction suspension cable

Embodiment 1

[0032] see Figures 1 to 4 , an elevator, comprising a car 3, a counterweight 60 and a traction carrying mechanism, the traction carrying mechanism comprises a traction carrying unit 2, a plurality of rotating wheels matched with the traction carrying unit 2, the traction carrying unit 2 is used It is used to carry and move the car 3, and wraps part of the circumference of the rotating wheel. Such as figure 1 As shown, in the present embodiment, the rotating sheave includes 1 traction sheave 1 , 2 car reversing sheaves 10 , and 1 counterweight reversing sheave 20 . One end of the traction bearing unit 2 is fixed above the hoistway, the other end extends downwards and bypasses the two car anti-rope pulleys 10 from below, then extends upwards, then bypasses the traction sheave 1 from above and then extends downwards, and finally Go around the counterweight anti-sheave 20 from below and extend upwards and be fixed above the hoistway.

[0033] Such as figure 2 As shown, the t...

Embodiment 2

[0042] see Figure 5 The difference between this embodiment and Embodiment 1 is that a protruding guide body 5 is provided in the middle of the first working surface 21 of the traction bearing unit 2, and a guide belt groove 8 is respectively opened on both sides of the second working surface 22. . Correspondingly, the center of the traction sheave 1 has a guide wheel groove 4 matching with the protruding guide body 5, and the two sides of the car anti-sheave 10 or the counterweight anti-sheave 20 respectively have a guide belt groove 8 to cooperate with. The rotating wheel protruding body 9.

Embodiment 3

[0044] see Figure 6 , The difference between this embodiment and Embodiment 1 is that the cross-sectional shape of the protruding guide body 5 is triangular, and the cross-sectional shape of the guide belt groove 8 is triangular.

Abstract

The invention discloses an elevator. The elevator comprises an elevator car and a dragging and bearing mechanism; the dragging and bearing mechanism comprises a dragging and bearing unit and rotating wheels, the dragging and bearing unit is of a flat strip shape and is provided with a first working face and a second working face, one of the first working face and the second working face is provided with a guide belt groove, and the other of the first working face and the second working face is provided with protruding guide bodies; the guide belt groove and the protruding guide bodies extend in the length direction of the dragging and bearing unit and are arranged in a staggered mode in the width direction of the dragging and bearing unit; and rolling surfaces of the rotating wheels are provided with rotating wheel protrusion bodies matched with the guide belt groove or guide wheel grooves matched with the protruding guide bodies, the guide belt groove is in clearance fit with the rotating wheel protrusion bodies, protruding guide bodies is in clearance fit with the guide wheel grooves, and gaps are reserved between the outer surfaces of the protruding guide bodies and the inner surfaces of the guide wheel grooves. The elevator has the advantages of effectively avoiding belt breakage and being low in cost, safe and reliable.

Description

technical field [0001] The invention relates to a traction elevator. Background technique [0002] Chinese patent CN101044084B discloses an elevator with a flat belt as a load-carrying mechanism. The guide grooves on the belt and the guide ribs on the pulley cooperate to overcome the defects that the flat belt slips and falls off from the pulley or is damaged in advance. However, the technical solution of this patent also has some disadvantages: (1) the guide rib of the pulley requires high processing precision and high material cost; (2) the thickness of the belt at the guide groove of the belt is thin, during operation, if the guide rib of the pulley If it does not fit well with the guide groove of the belt, one side is under too much pressure, which may cause the flat belt to break or greatly shorten its life. [0003] Chinese patent CN204138090U discloses a traction suspension cable for elevators. One side working surface of the traction suspension cable is a plane, whi...
