Abstract
The invention discloses a stable hoisting rope tension adjusting gear. Two or more hoisting ropes extend in the longitudinal direction, are parallel and are arranged in a line; the adjusting gear comprises a limiting board, rope rods and adjusting nuts, wherein the limiting board transversely extends; the rope rods extend in the longitudinal direction and pass through corresponding limiting holes in the limiting board; the adjusting nuts are arranged at the same ends of the rope rods; the number of the rope rods and the number of the limiting holes are equal to that of the hoisting ropes; the stable hoisting rope tension adjusting gear is characterized in that at least one rope rod and the corresponding limiting hole are transversely matched by a lock-key structure. With the adoption of the stable hoisting rope tension adjusting gear, by setting the lock-key structure between the rope rod and the corresponding limiting hole to achieve transverse matching, the twist of the rope rods is limited, the movement stability of the rope rods is guaranteed, so that the accuracy of the tension adjustment is improved. The lock-key structure can be arranged in a way of extending from one end of the limiting hole to the other end of the limiting hole, so that the limitation function of the rope rod inserted into the limiting hole is improved and the stability is further improved.
Description
Technical field
The present invention relates to a kind of tension-adjusting gear of elevator rope, particularly relate to a kind of device relying on nut to regulate hoist ropes tension force.
Background technology
The usual one end of hoist ropes is fixed on elevator counterweight, and the other end is fixed on car, is realized the lifting of elevator by forward and reverse rotation of traction sheave.Multi-rope friction hoisting form is a kind of form usually adopted, and has hoisting capacity large, the advantage that degree of safety is high.Along with the growth of hoist ropes period of service, the strength that each hoist ropes bears may produce difference, now needs tension-adjusting gear stressed to balance each hoist ropes, ensures lift running safety.The form that current hoist ropes tension-adjusting gear adopts nut to regulate each hoist ropes stressed respectively by rope bar usually, structure is simple, facilitates easy to operate.But the cross section of rope bar is generally circular, easily twist in the circular spacing hole of its positioning plate passed, and then the radial force size of impact rope bar, reduce the accuracy of tension adjustment.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of structure simple, stable, the tension-adjusting gear of the elevator rope that accuracy is high.
For achieving the above object, the technical solution used in the present invention is: a kind of stable type hoist ropes tension-adjusting gear, described hoist ropes is two or more, longitudinal extension is parallel to each other and press straight-though arrangement, described control apparatus comprises the positioning plate of horizontal expansion, extend longitudinally through the rope bar that on positioning plate, corresponding spacing hole is arranged, and be located at the setting nut of each rope bar with one end, the quantity of described rope bar and spacing hole equals hoist ropes quantity, it is characterized in that: an at least described rope bar is laterally coordinated by key structure with between corresponding spacing hole.
In a preferred embodiment of the present invention, comprise described whole rope bar further and laterally coordinated by key structure with between each self-corresponding spacing hole.
In a preferred embodiment of the present invention, comprise described key structure further and comprise the groove that the protrusion on spacing hole's inwall and bar of restricting close with described protrusion matching form, described groove is the strip groove extending to the other end from rope bar one end.
In a preferred embodiment of the present invention, the cross-sectional plane comprising described protrusion is further circular arc.
In a preferred embodiment of the present invention, the head cross-sectional comprising described protrusion is further circular arc, and the connecting portion cross section of protruding head and spacing hole's inwall is strip, and connecting portion section width is less than head section width.
In a preferred embodiment of the present invention, comprise described protrusion further and be positioned at spacing hole's longitudinal middle part.
In a preferred embodiment of the present invention, comprise described protrusion further and extend lengthwise into the other end from spacing hole one end.
In a preferred embodiment of the present invention, comprise 1.1-1.2 times that described spacing hole diameter is rope shank diameter further.
The invention solves the defect existed in background technology, the tension-adjusting gear of elevator rope of the present invention rope bar with key structure be set between corresponding spacing hole laterally coordinate, limit rope bar to twist, ensure that the stability of rope bar motion, be conducive to the accuracy improving tension adjustment.Key structure can be set and extend to the other end by spacing hole one end, strengthen interting the position-limiting action of bar of restricting in spacing hole, improving stability further.

Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, a kind of stable type hoist ropes tension-adjusting gear of the present invention, described hoist ropes 1 is two or more, longitudinal extension is parallel to each other and press straight-though arrangement, described control apparatus comprises the positioning plate 2 of horizontal expansion, longitudinal extension interts the rope bar 4 in the corresponding spacing hole 21 of positioning plate 2, and be located at the setting nut 6 of each rope bar 4 with one end, the quantity of described rope bar 4 and spacing hole 21 equals hoist ropes 1 quantity, on every root rope bar 4, between positioning plate 2 and setting nut 6, be also provided with recoil spring 8.Every root rope bar 4 with all pass through key structure between corresponding spacing hole 21 and laterally coordinate.Key structure comprises the groove 41 that the protrusion on spacing hole 21 inwall and bar 4 of restricting close with described protrusion matching form, and described groove 41 is the strip groove extending to the other end from rope bar 4 one end.Head 211 cross-sectional plane of described protrusion is circular arc, connecting portion 212 cross section of protruding head 211 and spacing hole 21 inwall is strip, connecting portion 212 section width is less than head 211 section width, and this structure can reduce the diametrically displacement of restricting between bar 4 and spacing hole 21 better.Described protrusion cross sectional shape also can be other geometric figure, such as vertical bar shape, isosceles trapezoid or equicrural triangle.Described protrusion extends lengthwise into the other end from spacing hole 21 one end, strengthens the position-limiting action to rope bar 5, also only can be arranged at spacing hole 21 longitudinal middle part, as shown in Figure 3.Described spacing hole 21 diameter is 1.1-1.2 times of rope bar 4 diameter, and making rope bar 4 longitudinal movement can not be subject to spacing hole 21 affects, and the space of restricting between bar 4 and spacing hole 21 can reduce as much as possible.In the present embodiment, described groove 41 is located at rope bar 4, protrudes and is located at spacing hole 21 inwall, also described groove 41 also can be located at spacing hole 21 inwall, and described protrusion is located at rope bar 4.
During installation, by the fag end of every root hoist ropes 1 by putting in order, be connected with rope bar 4 free end in corresponding control apparatus.When using this tension-adjusting gear, to the hoist ropes 1 needing adjustment of tonicity, rotate its corresponding setting nut 6.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to right.
