Abstract

The utility model discloses an ending loop bar for wire rope, wherein, deep holes are drilled on a sleeve; more than one large hole is extended along the deep holes; at least one radial section of the remained deep holes is provided with at least two triangle slits; a clamping flap is formed between the two slits; the wire rope is inserted into the deep hole; and external force can be used for deformation of the sleeve and closure of the slits, and the wire rope is then locked inside the deep hole. The utility model has small volume and no direct accessories.

Description

A kind of wire rope termination loop bar

Technical field

The utility model relates to a kind of wire rope termination loop bar.

Background technique

The terminating set of wire rope is used in elevator, the crane gear more.With the elevator is example, and terminating set one end is the threaded stem that links to each other with elevator cab, and an end is connected with wire rope.And between terminating set and the wire rope usually the mode with the pouring low melting alloy link to each other; Chinese patent application number is: disclosed in 01235802.9 the utility application " wedge block type wire rope terminating set " then adopts the mode of voussoir locking to link to each other.The former is big in the workload at installation scene, and there is potential safety hazard in melted alloy at the scene, and when maintenance, changes or to shorten the process of wire rope cumbersome; The voussoir locking mode that the latter adopts has overcome above-mentioned defective, and still, the volume of its tapered sleeve is big, has hindered the position of wire rope in the elevator rope hitch plate to arrange, and structure is relatively complicated, and member is more, and operation inconvenience also is unfavorable for reducing cost.

Summary of the invention

The purpose of this utility model is in order to provide a kind of volume little, the wire rope termination loop bar that member is few.

Main technical schemes of the present utility model is: be drilled with deep hole on the sleeve pipe, along the deep hole expansion more than one macropore is arranged, in the deep hole of remainder, have at least one section radially to offer at least two triangle slits, article two, form the card lobe between slit, after wire rope inserts in the deep hole, can make casing deformation, slit closure by external force, Steel wire rope lock is fixed in the deep hole.

The utility model utilizes the distortion of casing deformation, slit closure and deep hole to make the card lobe will insert wire rope locking tightly wherein, thus being connected of realization sleeve pipe and wire rope.The utility model volume is little, and direct attached member simple in structure, no during maintenance, as long as wire rope is cut off from nearly sleeve pipe, is changed new sleeve pipe and can be finished, and is easy to operate.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is an embodiment's of the utility model a structural representation;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is the structural representation of card lobe end face among Fig. 2.

Embodiment

As shown in Figure 1 and Figure 2, present embodiment is the wire rope termination loop bar that is used for elevator, be drilled with deep hole 21 on the cylinder-shaped sleeve 2, along deep hole 21 expansions three macropores 22 are arranged, macropore 22 is separated into three sections with deep hole 21, in these three sections deep holes 21, radially offer six triangle slits 6 of symmetry, form six card lobes 5 of symmetry between the slit 6, wire rope 1 inserts in the deep hole 21, can make sleeve pipe 2 be deformed into Hexagon by the external force clamping, slit 6 closures simultaneously, the aperture between the card lobe 5 dwindles, and card lobe 5 fixes on Steel wire rope lock in the deep hole.Sleeve pipe 2 ends are the threaded stems 3 that run through the absorbing part and connect elevator cab.For strengthening locking intensity, the end face 51 of card lobe 5 has dentation 4, and this dentation 4 can be trapezoidal or the rectangle on band inclined-plane.
