Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, and is stable, the tension-adjusting gear of the elevator rope that accuracy is high.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of stable type hoist ropes tension-adjusting gear; Said hoist ropes is two or more, and longitudinal extension is parallel to each other and press straight-though arrangement, and said control apparatus comprises the positioning plate of horizontal expansion; Longitudinal extension passes the rope bar that corresponding spacing hole is provided with on the positioning plate; And the setting nut of being located at the same end of bar of respectively restricting, the quantity of said rope bar and spacing hole equals hoist ropes quantity, it is characterized in that: laterally cooperate through the key structure between a said at least rope bar and corresponding spacing hole.
In preferred embodiment of the present invention, further comprise between said whole rope bar and each self-corresponding spacing hole laterally cooperating through the key structure.
In preferred embodiment of the present invention, comprise that further said key structure comprises the groove that matches with said protrusion shape on the protrusion on spacing hole's inwall and the bar of restricting, said groove is for extending to the strip groove of the other end from rope bar one end.
In preferred embodiment of the present invention, the cross-sectional plane that further comprises said protrusion is a circular arc.
In preferred embodiment of the present invention, the head cross-sectional plane that further comprises said protrusion is a circular arc, and the connecting portion cross section of protrusion head and spacing hole's inwall is a strip, and the connecting portion section width is less than the head section width.
In preferred embodiment of the present invention, comprise that further said protrusion is positioned at spacing hole's longitudinal middle part.
In preferred embodiment of the present invention, comprise that further said protrusion extends lengthwise into the other end from spacing hole's one end.
In preferred embodiment of the present invention, further comprise said spacing hole diameter 1.1-1.2 times for the rope shank diameter.
The invention solves the defective that exists in the background technology; The tension-adjusting gear of elevator rope of the present invention is provided with the key structure and laterally cooperates between rope bar and corresponding spacing hole; Limit the rope bar and twist, guaranteed the stability of rope bar motion, help improving the accuracy of tension adjustment.The key structure can be set extend to the other end, strengthen, further improve stability interting the position-limiting action of in spacing hole rope bar by spacing hole's one end.

The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the scheme drawing of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-3; A kind of stable type hoist ropes tension-adjusting gear of the present invention, said hoist ropes 1 is two or more, longitudinal extension is parallel to each other and press straight-though arrangement; Said control apparatus comprises the positioning plate 2 of horizontal expansion; Longitudinal extension interts the rope bar 4 in positioning plate 2 corresponding spacing holes 21, and the setting nut 6 of being located at the bar 4 same ends of respectively restricting, and the quantity of said rope bar 4 and spacing hole 21 equals hoist ropes 1 quantity; On the every rope bar 4, also be provided with recoil spring 8 between positioning plate 2 and the setting nut 6.Every rope bar 4 all laterally cooperates through the key structure with 21 of corresponding spacing holes.The key structure comprises the groove 41 that matches with said protrusion shape on the protrusion on spacing hole's 21 inwalls and the bar 4 of restricting, and said groove 41 is for extending to the strip groove of the other end from rope bar 4 one ends.Head 211 cross-sectional planes of said protrusion are circular arc; Connecting portion 212 cross sections of protrusion head 211 and spacing hole's 21 inwalls are strip; Connecting portion 212 sections width are less than head 211 sections width, this structure can reduce better to restrict the radially relative displacement of 21 of bar 4 and spacing holes.Said protrusion cross sectional shape also can be other geometric figure, for example vertical bar shape, isosceles trapezoid or equicrural triangle.Said protrusion extends lengthwise into the other end from spacing hole's 21 1 ends, strengthens the position-limiting action to rope bar 5, also can only be arranged at spacing hole's 21 longitudinal middle parts, and is as shown in Figure 3.Said spacing hole 21 diameters for the 1.1-1.2 of rope bar 4 diameters doubly, make rope bar 4 longitudinal movements can not receive spacing hole's 21 influences, and the space of 21 of rope bar 4 and spacing holes can reduce as much as possible.In the present embodiment, said groove 41 is located at rope bar 4, and protrusion is located at spacing hole's 21 inwalls, also can said groove 41 also can be located at spacing hole's 21 inwalls, and said protrusion is located at rope bar 4.
During installation, the fag end of every hoist ropes 1 by putting in order, is linked to each other with rope bar 4 free ends in the cooresponding control apparatus.When using this tension-adjusting gear,, rotate its corresponding setting nut 6 and get final product the hoist ropes 1 that needs adjustment of tonicity.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm technical scope according to the claim scope.
