The CN2432014Y patent of Patent Office of the People's Republic of China's bulletin in 30 days Mays calendar year 2001, name is called the rope binding clasp, this device comprises supporting sleeve and turnbuckle, in supporting sleeve, be provided with clamping cushion block and two oblique compact heaps with matching that the surface is convex surface, two oblique compact heaps interconnect by turnbuckle, bolt is threaded with another oblique tight piece after passing one of them oblique compact heap, and between two compact heaps enough spacings is arranged.This device can clamp rope by turnbuckle, but turnbuckle passes through manual adjustments, and the pretightning force that provides changes with the fastening degree of turnbuckle, breaks through the pretightning force upper limit if rope is subjected to pulling force, and rope skids easily.
Summary of the invention
It is definite value that the purpose of this utility model is to solve existing rope clamping device pretightning force, and the easy problem of slip of rope after the pulling force breakthrough pretightning force provides a kind of cable clamping device with the self-locking function.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cable clamping device, comprise fixed clamping seats, clamping seats is provided with the tapered sleeve that inside has bellmouth, tapered sleeve is embedded with conical chuck, conical chuck is made up of some wedges, adjacent wedge side is relative, and is gapped between the adjacent wedge, and the circular hole that passes for cable is arranged on the conical chuck axis.Conical chuck is embraced and is clipped on the cable and is nested in the tapered sleeve, when cable is subjected to external force and pulls, driving conical chuck further clamp-ons in the tapered sleeve, conical chuck is subjected to the inwardly effect of extruding of tapered sleeve, slit between each wedge reduces, the clamping force of cable is increased, and the suffered pulling force of cable is big more, and conical chuck is also big more to the clamping force of cable.
As preferably, the structure of described each wedge is identical, and the inner surface of wedge is as the hole wall of circular hole, and outer surface is the conical surface.The outer surface of wedge is that the conical surface and tapered sleeve match, inner surface be the face of cylinder as the circular hole hole wall, two sides are the plane, each wedge structure is identical, in the time of clamping cable each to stressed evenly.
As preferably, a side of described wedge is provided with alignment pin, and the another one side is provided with locating hole, and adjacent wedge matches by alignment pin and locating hole.The locating hole of the alignment pin of the side of a wedge and adjacent wedge side matches, and guarantees that each wedge can be synchronized with the movement.
As preferably, described wedge one has three, and angle is 120 degree between two sides of wedge.As other scheme, wedge also can two, four or more, and the angle between the wedge two sides is by the decision of wedge number, to guarantee to form a conical chuck after a plurality of wedges combinations.
As preferably, be fixed with the cable chuck on the cable that described conical chuck tail end stretches out.The cable chuck is fixed on the cable, the cable chuck can be unclamped when cable need spur, withstands the tail end of conical chuck after the cable chuck is fastening, and the stressed back of cable heads into conical chuck in the tapered sleeve by the cable chuck.
As preferably, described cable chuck comprises a U type frame and a pad, and the two ends of described U type frame are by being bolted on the pad, and cable is fixed between U type frame and the pad.
As preferably, be provided with anti-disk stripping between described conical chuck and the cable chuck.Prevent that conical chuck from getting loose, play the pad effect simultaneously, the pressure of cable chuck evenly is applied to the conical chuck afterbody.
As preferably, described anti-disk stripping is the porose disk in center.
As preferably, described clamping seats is an annular seating, and tapered sleeve is arranged on the ring wall of clamping seats, and the tapered sleeve axis is vertical with the clamping seats axis and intersect.
As preferably, the ring wall of described clamping seats is the arc of center evagination.The cable end is reserved certain length in order to regulating after passing clamping device, and one section cable of reservation can coil the ring wall inboard at clamping seats, and the structure of ring wall evagination can maintain cable makes cable be difficult for deviating from from clamping seats.
The suffered pulling force of the utility model cable is big more, and the clamping force of conical chuck is big more, plays the self-locking effect, and it is safe and reliable to clamp effect, and by conical chuck and cooperating of tapered sleeve carrying out fastening, simple in structure, easy for installation.
