Abstract
The utility model relates to a wire rope detection device, in particular to a wire rope breaking tool; the tension device comprises a mounting seat, wherein a V-shaped groove is formed in the mounting seat, a pair of wedge-shaped fixture blocks is movably arranged in the V-shaped groove, a rope winding groove is spirally arranged on the outer ring of the mounting seat, and a mounting rod for connecting the mounting seat to a tension machine is further arranged on the mounting seat; this frock of breaking simple structure, wedge fixture block only play the fixed action to the wire rope tip, and wire rope makes wire rope and tensile direction parallel through winding in the helicla flute of frock outer lane, and the taut atress of wire rope tightens up to the frock is inside, rather than with taut effort direct action at the anchor point position, avoids following anchor point position fracture, improves and detects the accuracy.
Description
Technical Field
The utility model relates to a wire rope detection device especially relates to wire rope frock of breaking.
Background
The ratchet device is an important part in the electrified railway, and applies constant tension to a contact line at a lower anchoring position to ensure stable current taking when a locomotive pantograph passes through. The ratchet wheel device consists of a frame and a steel wire rope, the quality of the steel wire rope is directly related to the safety of the whole contact anchor section, and the breaking force of the steel wire rope is a necessary test project specified by the device. The traditional steel wire rope breaking test tool is used for detecting the steel wire rope breaking limit through the stretching of a tensile machine after one end of a steel wire rope is clamped, in order to ensure that a steel wire rope anchoring nail is firm and does not fall off when the steel wire rope is broken, the clamping force of the tool is quite large, the steel wire rope structure of an anchoring point can be damaged by overlarge clamping force, the steel wire rope is easily broken from the anchoring point when the steel wire rope is broken, and therefore accurate breaking data cannot be obtained.
SUMMERY OF THE UTILITY MODEL
In order to avoid wire rope from anchor point snap, guarantee that the snap detects the accuracy when snapping wire rope, the utility model discloses the technical scheme who adopts is:
the utility model provides a wire rope frock of breaking, includes the mount pad on be equipped with V type groove V type inslot activity be provided with a pair of wedge fixture block the mount pad outer lane spiral be provided with around the rope groove the mount pad on still be equipped with the installation pole of being connected to this mount pad on the tensile machine.
Furthermore, the mounting seat comprises a bottom plate, a main clamping plate, an auxiliary clamping plate and a rope winding plate, and the V-shaped groove is formed between the main clamping plate and the auxiliary clamping plate.
Furthermore, the rope winding grooves are sequentially spirally arranged from the main clamping plate to the rope winding plate.
Furthermore, the main clamping plate, the auxiliary clamping plate and the rope winding plate are integrally fixed on the bottom plate through bolts.
Furthermore, a tooth surface is arranged on the wedge-shaped fixture block.
The snapping tool is simple in structure, the wedge-shaped clamping blocks only play a role in fixing the end portions of the steel wire ropes, the steel wire ropes are enabled to be parallel to the stretching direction through winding in the spiral grooves in the outer ring of the tool, the steel wire ropes are tensioned to tighten towards the inside of the tool, the tensioning acting force is not directly acted on the anchoring point position, the fracture from the anchoring point position is avoided, and the detection accuracy is improved.

FIG. 2 is an exploded view of the present invention;
fig. 3 is a schematic diagram of a wire rope winding.
Detailed Description
In order to understand with the clarity the utility model discloses technical scheme, it is right below to combine the figure the utility model discloses the structure does further detailed description, draw disconnected frock as shown in fig. 1 to include mount pad 1, be equipped with V type groove 2 on mount pad 1, V type inslot 2 internalization is provided with a pair of wedge fixture block 3, spiral arrangement has wire winding groove 4 in mount pad 1 outer lane, still be equipped with installation pole 5 on mount pad 1, installation pole 5 can install this frock on the tensile machine, when coiling wire rope is shown in fig. 3, now place wire rope A one end between two wedge fixture block 3, it is the tight wire rope tip of wedge fixture block 3 clamp to move wedge fixture block 3 to the narrower one side of V type groove 2, then twine wire rope on wire winding groove 4 of mount pad 1 outer lane, because wire winding groove 4 spiral sets up, wire rope can twine a whole circle, thereby can guarantee that wire rope A is parallel with the direction of V type groove 2 all the pulling force is the tight wire rope clamping groove tip all the time (namely according to wire rope automatic adjustment from the position point of being qualified for next round of wire rope), when drawing the test the wire rope 3 can be to the drive wire rope, thereby can not be more tight the tight wire rope winding groove on the wire rope winding groove, thereby can not be located the tight in the later stage of the accurate drawing, thereby the tight wire rope drawing, thereby can not be established the tight wire rope drawing the tight of the tight normal line of the tight of wire rope winding groove in the later stage of drawing 3, thereby can not drawing, thereby the tight in the later stage of drawing, thereby the tight line of drawing, thereby the tight of drawing.
The installation seat 1 in the above structure can be an integral body, but considering the processing difficulty, saving the processing cost and improving the processing efficiency, the installation seat 1 is set to be a combined form, as shown in fig. 2, the installation seat 1 comprises a bottom plate 1-1, a main clamping plate 1-2, an auxiliary clamping plate 1-3 and a rope winding plate 4, in this embodiment, the main clamping plate 1-2, the auxiliary clamping plate 1-3 and the rope winding plate 1-4 are an integral body (which can be processed and formed by a numerical control processing center) and fixed on the bottom plate 1-1 through bolts, of course, the main clamping plate 1-2, the auxiliary clamping plate 1-3 and the rope winding plate 1-4 can be processed and assembled together through bolts respectively, at this time, a V-shaped groove 2 can be arranged between the main clamping plate 1-2 and the auxiliary clamping plate 1-3, the rope winding groove 4 is arranged spirally along the main clamping plate 1-2 to the rope winding plate 1-4, so that the bottom plate 1-1 and the main clamping plate 1-2, the auxiliary clamping plate 1-3 and the rope winding plate 1-4 are arranged, the service life of the structure can be reduced, and the processing cost can be reduced from zero parts. In order to improve the friction force of the wedge-shaped fixture block 3 to the steel wire rope, the surface of the wedge-shaped fixture block is provided with a tooth surface 3-1.
