Abstract
The invention relates to a simple tensioner of lossless steel cables. The simple tensioner is characterized by comprising a U-shaped fixing bracket, wherein two top ends of the U-shaped fixing bracket are hinged with fixing pulleys respectively; the bottom of the U-shaped fixing bracket is connected with a regulating stem which can go up and down relative to the U-shaped fixing bracket; the upper end of the regulating stem is connected with a detachable regulating pulley; and the regulating pulley and the fixing pulley are arranged at a same longitudinal plane. The regulating stem is in threaded connection with a stair-step shaped regulating nut, and the excircle of the stair-step shaped regulating nut is connected with a through hole at the bottom of the U-shaped fixing bracket smoothly. The simple tensioner disclosed by the invention has simple principles, low manufacturing cost and great popularization value both in power transmission line works and various cableways such as forestry cableways, freight transport cableways, passenger transport cableways, overhead power transmission lines and the like.
Description
Technical field
The present invention relates to the simple and easy tensioner of a kind of harmless steel rope, be applied to the harmless tensioning of steel rope also is applicable to the harmless tensioning of other gentle rope.
Background technology
At present, steel rope turnbuckle commonly used also claims that bolt with flange or turnbuckle are as shown in Figure 1, can only connect steel rope through two ends, the degree of tightness that could regulate steel rope, and the scope of regulating is very limited.Only be applicable to fixed steel rope adjusting; Like slack-free guy wire etc., and need will embed when mounted in the steel rope, with circuit be in-line; Can only be fixed; And can not walk around pulley, can not be in good time tensioning steel rope at an arbitrary position, more can not satisfy the tensioning of closed cycle steel rope (gentle rope).Under the situation of position of the bearing that can not regulate the closed cycle steel rope or location pulley, tensioning closed cycle steel rope is just pretty troublesome.Because of turnbuckle must be connected, often to take bearing apart or cut off steel rope and carry out tensioning, operating difficulties, and steel rope is had damage in the access section, and therefore, be badly in need of easy operation, do not damage steel rope, and can satisfy the optional position, the slack-free tensioner of any amount.
Summary of the invention
The object of the present invention is to provide the simple and easy tensioner of a kind of harmless steel rope, solved present steel rope effectively and in the tensioning process, occurred damaging and unhandy problem.
The invention is characterized in: the simple and easy tensioner of a kind of harmless steel rope; It is characterized in that: comprise the U-shaped fixed mount; Two tops of said U-shaped fixed mount are hinged with tight pulley respectively; The bottom of said U-shaped fixed mount is connected with the adjust bar of U-shaped fixed mount up-down relatively, and the upper end of said adjust bar is connected with removably adjusting knurl, and said adjusting knurl and tight pulley are on same longitudinal plane.
Said adjust bar is threaded with stepped setting nut, through hole smooth be connected of the cylindrical of said stepped setting nut bottom the U-shaped fixed mount.
Advantage of the present invention:
1) do not make steel rope 360 degree turnovers, to the steel rope zero damage;
2) steel rope of connecting again after need not blocking keeps the integraty of steel rope;
3) two ends are fixed or closed cycle single or many steel ropes can realize that all any amount tensioning regulates;
4) do not influence steel rope work operation;
5) it is big, unrestricted basically to be conditioned the wirerope diameter scope;
6) easy to operation, cost of manufacture is low.

Wherein: the 7-steel rope.
The specific embodiment
With reference to figure 2, Fig. 3 (a), Fig. 3 (b) and Fig. 4; The simple and easy tensioner of a kind of harmless steel rope; Comprise U-shaped fixed mount 4, two tops of said U-shaped fixed mount 4 are hinged with tight pulley 2 respectively, and the bottom of said U-shaped fixed mount 4 is connected with the adjust bar 3 of U-shaped fixed mount up-down relatively; The upper end of said adjust bar 3 is connected with removably adjusting knurl 1, and said adjusting knurl 1 and tight pulley 2 are on same longitudinal plane.
Above-mentioned adjust bar 3 is threaded with the stepped setting nut 5 of being located at downside position, U-shaped fixed mount 4 bottom; The smooth connection of through hole of the cylindrical of said stepped setting nut 5 and U-shaped fixed mount 4 bottoms; The bottom of setting nut 5 and U-shaped fixed mount 4 is connected through the smooth side of radial bearing formula, and is free to rotate between setting nut 5 and U-shaped fixed mount 4 bottom circular aperture.And adjust bar 3 goes up and down through the threaded adjusting of the setting nut 5 of U-shaped fixed mount 4 bottom downsides, like Fig. 3 (a).
Above-mentioned adjust bar 3 is threaded with the stepped setting nut 5 of being located at upside position, U-shaped fixed mount 4 bottom; The smooth connection of through hole of the cylindrical of said stepped setting nut 5 and U-shaped fixed mount 4 bottoms; The bottom of setting nut 5 and U-shaped fixed mount 4 is connected through the smooth side of radial bearing formula, and is free to rotate between setting nut 5 and U-shaped fixed mount 4 bottom circular aperture.And adjust bar 3 goes up and down through the threaded adjusting of the setting nut 5 of U-shaped fixed mount 4 bottom upsides, like Fig. 3 (b).
Above-mentioned adjust bar 3 upper ends are connected with adjusting knurl 1 through just unloading pivot pin 6.For ease of the installation of the regulative mode steel rope shown in Fig. 3 (b), also can the fixed pulley on the U-shaped fixed mount be connected through just unloading pivot pin.
The practical implementation process:
Working process
Tensioner is through three pulley positioning principles, and that takes adjusting knurl apart just unloads pivot pin, and adjusting knurl is unloaded earlier; Snap in to set up again behind the steel rope that is tensioned and just unload pivot pin, making rope be in state, guarantee that steel rope all is in the chute of three pulleys like Fig. 2; Regulate setting nut; Make the adjusting knurl motion, thereby change three wheel location, steel rope (gentle rope) is become curve (Fig. 2 to Fig. 3 (a), 3 (b)) by straight line all can play the effect of regulating steel rope.The size that changes adjust bar and fixed mount just can realize the adjusting of different magnitudes, and the concrete requirements of making and the size of each parts do not elaborate at this.
Its concrete principle of work is: through three pulley positioning principles; Regulate the relative position of three-wheel through adjusting knurl; Steel rope (gentle rope) is become curve by straight line, the bending length of steel rope (gentle rope) is carried out timely adjustment control, thereby change the tensioning state of steel rope (gentle rope).Be illustrated in figure 2 as the simple and easy tensioner structural representation of steel rope (gentle rope).Be depicted as the work scheme drawing like Fig. 3 (a), Fig. 3 (b).
The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
