Abstract

The utility model discloses an anti-twist wire rope clip which pertains to the field of electricity safety apparatus. The anti-twist wire rope clip mainly comprises a support, a pull ring, an upper jaw, a lower jaw, a front connecting plate and another front connecting plate, a back connecting plate and another back connecting plate, wherein the pull ring is connected at the end part of one end of the support by a hinge pin; the support, a group of front connecting plates and a group of back connecting plates are connected with a group of hinge pins; the upper jaw is connected with the middle ends of the group of front connecting plates by a jaw pin; the lower ends of the group of front connecting plates and the group of back connecting plates are connected to a lower jaw seat by a group of hinge pins; the surfaces of the upper jaw and the lower jaw, which are contacted with the wire rope, are respectively provided with a clipping and lifting groove; and small bumps are asymmetrically arranged at two sides of the groove. The anti-twist wire rope clip has simple structure, can effectively prevent the wire rope from slipping, can effectively prevent the wire rope from twisting, and has high safety.

Description

A kind of anti-steel wire rope fixing-line device of turning round

Technical field

The utility model relates to a kind of safety device, more particularly, is a kind of anti-steel wire rope fixing-line device of turning round of the usefulness as power construction department unwrapping wire and stringing.

Background technology

When work high above the ground, need use fixing-line device and guarantee people's safety, because of the cross section of steel wire rope all is circular usually, therefore the working face of existing fixing-line device is designed to the semicircle of indent, form whole circular trough during clamping, effect lower semi-circular jaw in the tight power of song can clamp steel wire rope, and contact-making surface produces bigger frictional force, thereby clamps steel wire rope; Yet the circular trough of indent is that line contacts with steel wire rope, contact area is little, need bigger clamping force could clamp steel wire rope, in case and body weight is heavy slightly, insufficient clamping force will occur, and then cause steel wire rope to appear at the phenomenon that wire blocking port skids, and twisting also very easily appears aloft in steel wire rope, the easier steel wire rope problem of slip that causes, this directly threatens the safety of the person.

Summary of the invention

In order to solve deficiency of the prior art, the utility model provides a kind of to be prevented turning round the steel wire rope fixing-line device, has effectively increased the clamping force of fixing-line device, and has adopted the mode of multiple spot contact, has solved the problem that steel wire rope skids and twists.

The purpose of this utility model realizes by the following technical solutions:

A kind of anti-steel wire rope fixing-line device of turning round, primary structure comprises support, draw ring, upper jaw, lower jaw, connecting plate before one group, connecting plate after a group, draw ring is connected by bearing pin in support one end end, support is by before one group, back connecting plate is connected with one group of bearing pin, and upper jaw is connected with the middle-end of connecting plate before a group by a jaw pin, and is fixed together with screw, the lower end of one group of forward and backward connecting plate is connected the lower jaw seat by one group of bearing pin, and fixed with screw, upper and lower jaw has card and rises groove on the contact-making surface of using with steel wire rope, and the groove both sides have asymmetric small salient point.

The utility model is provided with asymmetric small salient point on the groove both sides, make groove energy grandmother's the steel wire rope that blocks make it non-slip, and can not damage steel wire rope, the small salient point of She Zhiing has also increased the clamping force of groove simultaneously, adopt the mode of multiple spot contact, solved steel wire rope appearance twisting and caused problem of slip.

Description of drawings

Fig. 1 is a decomposition texture schematic diagram of the present utility model;

Fig. 2 is the closed schematic diagram of upper and lower jaw of the present utility model;

Fig. 3 is the partial enlarged drawing of Fig. 2.

Among the figure: connecting plate before 1,2 back connecting plates, 3 lower jaws, 4 upper jaws, 5 another back connecting plates, 6 supports, 7 draw rings, 8,9,10,11,13,16 pins, 12 another preceding connecting plates, 14,15 screws, 17 salient points.

The specific embodiment

Below in conjunction with accompanying drawing utility model further is described;

With reference to accompanying drawing 1, a kind of anti-steel wire rope fixing-line device of turning round, primary structure comprises support 6, draw ring 7, upper jaw 4, lower jaw 3, preceding connecting plate 1 and another preceding connecting plate 12, back connecting plate 2 and another back connecting plate 5, draw ring 7 is connected by bearing pin 8 in support 6 one end ends, support 6, before one group, back connecting plate is connected with one group of bearing pin, and upper jaw 4 is connected with the middle-end of connecting plate before a group by a jaw pin 10, and is fixed together with screw 14, before one group, the lower end of back connecting plate is by one group of bearing pin 9,11,13,16 connect the lower jaw seat, and fixed with screw 15, on, lower jaw has card and rises groove on the contact-making surface of using with steel wire rope, the groove both sides have asymmetric small salient point 17.

During use, steel wire rope is positioned in the groove that forms between upper and lower jaw, pulling draw ring and connecting lever motion press down, and clamp steel wire rope, and steel wire rope and groove inwall produce frictional force, and when frictional force was enough big, fixing-line device blocked steel wire rope; In case steel wire rope produces twisting, the small salient point at upper and lower jaw place will hinder the twisting of steel wire rope, and small salient point has also strengthened the clamping force of upper and lower jaw to steel wire rope simultaneously, prevents that skidding from appearring in steel wire rope.

Claims

1. prevent turning round the steel wire rope fixing-line device for one kind, primary structure comprises support, draw ring, upper jaw, lower jaw, preceding connecting plate and another preceding connecting plate, back connecting plate and another back connecting plate, it is characterized in that: draw ring is connected by bearing pin in support one end end, and support, one group of forward and backward connecting plate are connected with one group of bearing pin, and upper jaw is connected with the middle-end of connecting plate before a group by a jaw pin, and fixed with screw, the lower end of one group of forward and backward connecting plate connects the lower jaw seat by one group of bearing pin, and is fixed with screw, upper and lower jaw with the contact-making surface of steel wire rope on have card and rise groove.

2. according to claim 1ly a kind ofly anti-turn round the steel wire rope fixing-line device, it is characterized in that described groove both sides have asymmetric small salient point.
