Abstract

The utility model relates to a rope-breakage safety device which is arranged on a hanging cage (19) of a person and cargo two-purpose elevator. A rope-breakage signal following mechanism is arranged on a cross beam (2) of a hanging cage (19). An elevating steel cable (4) is arranged on the hanging cage (19) of the two-purpose elevator. Two methods of installation and use are arranged in figures 1 and 2 in China. Thus, the utility model can be installed to use. The utility model makes loosening or tightening signals of the elevating steel cable (4) transferred to an electromagnet (14) through a rope-breakage signal following pulley (5) by a contact plate (8) of a compression spring (7), a stroke switch and a leading wire. Thereby, an embracing braking wedge block (13) is tightly braked or is disengaged between a vertical post (3) of a steel duct of the two-purpose elevator and a fixing sloping block (12).

Description

The rope-breaking safe device of the dual-purpose elevator of people's goods

The utility model belongs to the rope-breaking safe device of the dual-purpose elevator of people's goods, and the generation and the cage of the cage falling accident that can be used for prevents to break restricts and cause stop halfway.

9.1,2.1 regulations in the GB10055-88 new standard of implementing in 1989: the separate hoist rope number of the dual-purpose elevator of SS people's goods must not be less than 2.It is very big that this is defined in technical difficulty, uneconomical, use inconvenience.

The purpose of this utility model is to provide a kind of and can frequently uses, and braking is strong, breaks away from flexibly, and can catch the rope-breaking safe device of the dual-purpose elevator of people's goods of disconnected rope signal automatically.

The utility model is to realize its purpose as follows: the rope-breaking safe device of the dual-purpose elevator of people's goods is installed on the cage, the disconnected signal tracking mechanism that restricts is installed on the crossbeam of cage, connect four stop mechanisms with lead, be installed on two edge columns of cage, two of every limit peaces.Disconnected rope signal tracking mechanism: the disconnected rope of hoist rope contact signal tracking pulley, pulley and with contact plate and spring in cover combined integrated, contact by the roller on the travel switch on contact plate and the spring overcoat, be set with compression spring inside and outside the spring.This mechanism's automatic control cage, cage moves up and down or stop off, disconnected rope, outage, hoist rope produces lax or tensioning, the signal of disconnected rope, by hoist rope pushing or the disconnected rope of disengaging signal tracking pulley, drive contact plate and promote or leave roller on the travel switch, make its energising or outage, during energising, the tractive magnet of four stop mechanisms given electric signal transmission by lead, traction lever, weight is mentioned, and drives the brake holding voussoir and falls, and the gap occurs, cage does not move up and down and can rub, or stop, disconnected rope, during outage, ct-off signal passes to electromagnet, outage, traction lever, weight falls, and brake holding voussoir wedge is got on, and fills up the gap.Make the brake holding voussoir that has brake band, at the elevator steel pipe post with have fixedly breaking away between the skewback or stopping tight of scroll wheel.Cage moves preceding first bird cage up and down, alleviates the pressure to the brake holding voussoir.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1. for the utility model structural representation is always schemed;

Fig. 2. be disconnected rope signal tracking structural scheme of mechanism;

Number among the figure: 1. gin wheel; 2. cage crossbeam; 3. elevator steel pipe post; 4. hoist rope; 5. disconnected rope signal tracking pulley; 6. travel switch; 7. compression spring; 8. contact plate; 9. cage column; 10. spring overcoat; 11. cover in the spring; 12. fixing skewback; 13. brake holding voussoir; 14. electromagnet; 15. lever; 16. weight; 17. electromagnet stent; 18. lead; 19. cage; 20. roller.

With reference to Fig. 1-2, the disconnected signal tracking mechanism that restricts is installed on the crossbeam (2) of cage (19), hoist rope (4) is gone up installation and application at the cage (19) of elevator, domestic have two kinds, see Fig. 1, Fig. 2, can install and use this device, cage (19) promotes or the preceding first bird cage (19) that descends, hoist rope (4) tensioning, the disconnected rope of pushing signal tracking pulley (5), compression spring (7) is compressed, and makes the roller (20) on contact plate (8) the promotion travel switch (6), make its energising, lead (18), fax passed tractive magnet (14) adhesive in four stop mechanisms that are installed in cage (19) two edge columns (9), armature drives lever (15), weight (16) is mentioned, and brake holding voussoir (13) pulls down, and produces the gap, cage (19) is gone up or operation beginning down, can not produce friction.Outage, when rope is broken in stop off and generation, hoist rope (4) is disconnected, disconnected rope signal tracking pulley (5) is lost pressure, compression spring (7) is elongation outwards, the roller (20) that drives on contact plate (8) and the travel switch (6) breaks away from, travel switch (6) outage makes stop mechanism tractive magnet (14) outage, armature falls, driving lever (15) falls weight (16), brake holding voussoir (13) forces up, fixedly the gap between skewback (12) and the elevator steel pipe post (3) fills up, the brake holding braking that makes cage (19) safety makes the shape of its brake holding face identical with the shape of elevator steel pipe post for reducing brake holding voussoir (13) to the damage of elevator steel pipe post (3), and is equipped with brake band (asbestos copper wire drag band) on the steel pipe post of elevator (3); For brake holding voussoir (13) is broken away from flexibly, fixedly be equipped with scroll wheel on the skewback (12).

The utility model is resolved rope signal tracking device because of its setting, and is equipped with brake band and scroll wheel on brake holding face, makes it not need manual operation, just dynamic braking can be arranged, and breaks away from flexibly; Because of the direct lock of its brake holding voussoir at the steel pipe post of elevator with fixedly between the skewback, do not need guide rail and safety rope are set specially, thereby reduced cost.
