Abstract

The utility model discloses a sling for fastening or positioning a steel rope, in particular to a sling for the knot of a steel rope, comprising a body, a housing, a joint hinge and a steel rope retaining pin. The utility model has the advantages of simple structure, easy assembly and disassembly, low cost, long service life, and reasonable design. The sling for the knot of a steel rope can replace the manual dismounting banjo unions and the fastening method for steel rope pouring alloys, and can reduce the labour intensity, being suitable for lot productions.

Description

Sling for knot of steel rope

What the present invention relates to the fastening or location of steel ropes withholds device, is the accessory of lifting loading-unload machine.

In the lifting handling process, adopt the steel ropes of all size in a large number, the thickest diameter reaches 40 millimeters, is used for fastening cable wire, location dead rope.Binding between cable wire and the cable wire, between cable wire and the object need be born the load greater than the trouble free service of cable wire own.The technology that the crowd knows is that steel cable is cut to Len req, makes eye splice or pours into a mould the alloy fastening with socket at its bitter end then.

The manufacturing process of cable wire eye splice is bitter end to be taken apart to survive thigh earlier, is punctured in the root thigh in desired location with the method for artificial woollen yarn knitting, is bound by tarred line then, form like this one can fastening cable wire eye splice.This way not only labour intensity is big.Complex process, operating personal need be grasped technical skill and waste raw MAT'L.As the cable wire of 32 millimeters of the diameters of pegging graft need three strong and time of one day of peopleization of woollen yarn knitting experience is arranged, and about two meters of waste steel cable.

Cable wire cast alloy fastening manufacturing process is earlier the cable wire end to be stretched in the cast steel socket hole, and every on steel wire is unclamped the back hook, and the low fused gold of cast is made the steel ropes that can locate dead rope so then.This method formality is numerous and diverse, and requirement is high, expense is big and be not suitable for field fabrication.

Purpose of the present invention just provides the accessory of a kind of lifting loading and unloading, when need are made steel ropes, as long as steel cable is cut into Len req, loads onto this and withholds device and promptly can be used for fastening cable wire, the location dead rope.This withholds the device easy accessibility, and cost is low, long service life, suitable batch production again.

Whole device is made up of other part such as body, shell, joint hinge, cable wire stop pin.Section direction car becomes several concavo-convex slotted eyes about in the body apertures, works to tighten cable wire, 8 above better effects if; Middle car is made a big garden post endoporus and is held the cable wire that is inserted with stop pin; Body is formed by mill into two half block bodies along line of centers, and leaves the surplus that foot can clamp cable wire, is drilled with dowel hole and spring eye on two half block planes, prevents that body from can make body throw off under spring force when producing displacement and mobile cable wire under external force.Body one sidecar makes that cone matches in outer cone and the shell, and the shell opposite side is threaded with the joint hinge implementation, thread looseness when loading onto stop screw at the screw-threaded engagement place and preventing to use.The installation of steel cable bitter end is withheld device and is achieved like this, to locate in the cable wire stop pin insertion steel cable, go up two block bodies again and coat grease and be inserted in the shell, and piece together with joint hinge screw thread and outer casing screw and tightly to carry out pull test, loading onto stop screw after normal, to prevent to withhold device loosening.Joint hinge has A, two kinds of forms of B, and the device of withholding of A type joint hinge is used for fastening cable wire; The device of withholding of Type B joint hinge is used to locate dead rope.

It is of the present invention that to withhold device reasonable in design, artificial dismounting and the cable wire cast alloy fastening of replacing simple in structure, and it is easy to use to save man-hour, reduces labor intensity.Owing to withhold device and steel cable reaches the interference close contact, and have self-lock ability, safe and reliable during work, but service life long this withhold repeatedly steel ropes of device long-term use, so can save great deal of raw materials and reduction use cost.

Below in conjunction with accompanying drawing invention is described in further detail.

Fig. 1 is the device of withholding of A type joint hinge;

Fig. 2 is the device of withholding of Type B joint hinge.

With reference to accompanying drawing, the shell (2) of withholding device is inserted in the cable wire of corresponding specification, from 90 millimeters at cable wire one end (device of withholding that refers to 4.5～7.5 tonnes of workloads), with hammer cable wire stop pin (11) is inserted in the steel cable, aim at the steel cable that inserts the stop pin position and go up the body (6) of two half blocks again, intrinsic big garden post endoporus (5) is packed just have into one section steel pipe of stop pin, and in knock hole (9), put into locating dowel pin and spring in the spring eye (8), mobile shell (2) is inserted in the body (6), the packing ring (3) of then joint hinge (1) thread end being packed into applies in the shell (2), steel ropes is tightened up till.(4) be concavo-convex slotted eye, (7) are grease storage garden arc groove.

Pull test load of the present invention is generally two times of safe-working loads, and test is held time and is no less than 5 minutes, checks cable wire after the off-load and withholds device, thinks qualified and loads onto limit screw at the screw thread contact-making surface afterwards, comes into operation. As when making the dead rope locating button, with joint hinge Type B (10) transposing joint hinge A type (1), Type B joint hinge and the difference structurally of A type joint hinge are that the joint hinge ring moves to the side by end face, and steel cable can all pass joint hinge. Installation situation all the other formalities except cable wire latch (11) need not fill are the same.

Claims

1, a kind of be used for the fastening or location of steel ropes withhold device, it is characterized in that this withholds device and be made up of body (6), shell (2), joint hinge (1), cable wire stop pin (11), body (6) one sidecars are made outer cone and are inserted in the inside and outside shell of the interior cone of shell (2) (2) opposite side and joint hinge (1) and carry out and be threaded, and car is made a big garden awl endoporus and held the cable wire that is inserted with cable wire stop pin (11) in the middle of the body (6).

2, the device of withholding according to claim 1 is characterized in that described body (6) forms by mill into two half block bodies along line of centers, is drilled with dowel hole and spring eye on two half block body planes; Several concavo-convex slotted eyes of sidecar system in two half block bodies, 8 above better effects if.
