Abstract
The invention provides a device for detecting breaking or loosing of a steel wire rope of a household elevator. The device comprises a base, a steel wire rope head, a metal block, a forcible contact switch, a spring and a junction box. The device provided by the invention is simple in structure, small in size, occupies small pace, can be added on the head of any steel wire rope, and is especially applied to a household elevator product which has high requirement on the space and needs compact design.
Description
Technical field
The present invention relates to a kind of for detection of home lift wire cable rupture or lax device.
Background technology
All larger for detection of the device volume of steel wire rope looseness on general elevator, be not too applicable to the very compact home lift product of Structure of need.
Summary of the invention
Provided by the invention a kind of for detection of home lift wire cable rupture or lax device, simple in structure, small and exquisite, take up room little, and can be installed on the fag end of any steel rope, be particularly useful for for space requirement very highly, need in the home lift product of compact design.
In order to achieve the above object, the invention provides a kind ofly for detection of home lift wire cable rupture or lax device, this device comprises pedestal, cable wire end, derby, pressure contact switch, spring and connection box;
On pedestal, be provided with perforate;
Spring is arranged on derby inside;
Force contact switch to comprise contact part and wire jumper part, contact part) be fixed on the both sides of derby, wire jumper is partly arranged on pedestal, and the position of wire jumper part is corresponding with contact part;
The upper end of cable wire end successively through perforate, spring and derby on pedestal, passes from the top of derby from the bottom up, and the lower end of cable wire end is for connecting steel wire ropes.
Described contact part is connected with wire, and two or more pressure contact switchs are cascaded, and are connected in the lump connection box.
Described pressure contact switch also comprises fastener.
Described cable wire end also comprises packing ring and nut, for fixing cable wire end.
Whether device provided by the invention can be installed on the fag end of ready-made steel rope, lax for detection of steel rope.Once there is fracture or lax in steel rope; this device can cut off a secondary safety contact automatically; thereby to apparatus for controlling elevator, send lax signal of steel rope, apparatus for controlling elevator will be learnt wire cable rupture or lax situation have occurred, and take safety method.This apparatus structure is simple, small and exquisite, takes up room little, and can be installed on the fag end of any steel rope, is particularly useful for for space requirement very highly, needs in the home lift product of compact design.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is derby and the enlarged drawing of forcing contact switch;
Fig. 3 is the enlarged drawing of connection box;
Fig. 4 is the cutaway view of derby and spring;
Fig. 5 is the exploded view of forcing contact switch.
The specific embodiment
Following according to Fig. 1～Fig. 5, illustrate preferred embodiment of the present invention.
As depicted in figs. 1 and 2, the invention provides a kind ofly for detection of home lift wire cable rupture or lax device, this device comprises pedestal 1, cable wire end 2, derby 3, forces contact switch 4, spring 5 and connection box 6;
As shown in Figure 5, on pedestal 1, be provided with perforate 11;
As shown in Figure 4, spring 5 is arranged on derby 3 inside;
As shown in Figure 5, force contact switch 4 to comprise contact part 41 and wire jumper part 42, contact part 41 is fixed on the both sides of derby 3, wire jumper part 42 is arranged on pedestal 1, and the position of wire jumper part 42 is corresponding with contact part 41, and contact part 41 is connected with wire, two or more pressure contact switchs 4 are cascaded, be connected in the lump connection box 6(as shown in Figure 3), this pressure contact switch 4 also comprises fastener 43, and wire jumper part 42 is fixed on pedestal 1;
The upper end of cable wire end 2 is from the bottom up successively through perforate 11, spring 5 and derby 3 on pedestal 1, from the top of derby 3, pass, the lower end of cable wire end 2 is for connecting steel wire ropes, and this cable wire end 2 also comprises packing ring 21 and nut 22, for fixing cable wire end 2;
Should be as follows for detection of the principle of work of home lift wire cable rupture or lax device:
When steel rope does not occur in fracture or lax situation, due on steel rope with load, cable wire end 2 can tightly be pressed in derby 3 on pedestal 1, the spring 5 of derby 3 inside is in compressive state, force the contact part 41 of contact switch 4 to contact with its wire jumper part 42, this pressure contact switch 4 always can be in closure state, once there is fracture or lax in certain steel cable, the inner spring 5 of compression originally of derby 3 that this steel rope is corresponding will be released, derby 3 and cable wire end 2 thereof will be pushed up, simultaneously, force contact switch 4 also together to be taken up, contact part 41 departs from its wire jumper part 42, now force contact switch 4 meetings in off-state, until wire cable rupture or lax situation are repaired, because a plurality of pressure contact switchs 4 are cascaded, only have when all steel ropes are during all in tensioning state, wire in connection box 6 is just in UNICOM's state, as long as there is any steel cable that fracture or lax occurs, wire in connection box 6 will be in off-state, this wire will be connected to the control system of elevator, the break-make that control system detects this wire has judged whether to occur wire cable rupture or lax unsafe condition.
This apparatus structure is simple, small and exquisite, takes up room little, and can be installed on the fag end of any steel rope, is particularly useful for for space requirement very highly, needs in the home lift product of compact design.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Those skilled in the art, read after foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
