Abstract

A wire-rope unidirectional lock relates to a device for binding and fastening railway transport goods. As a novel binding and fastening rigging, the unidirectional lock includes a unidirectional lock, wire ropes and a buckle. The utility model is characterized in that a unidirectional-lock internal slide block, a spring, a bottom cover are connected in series, the bottom cover is fixedly connected with casing, and a compression spring can slide in the casing when the slide block bears force; one end of the casing is cone-shaped, the other end is cylinder-shaped, a lug is arranged on a side surface, and a round hole is formed on the lug; and the slide block is cone-shaped, round through holes are formed in the axial direction, two layers of round holes are formed in the radial direction, three holes on each layer are distributed on the periphery and communicated with the axial round holes, and steel balls are arranged in the round holes and can rotate in the holes. When the goods need to be bound, one end of the wire rope penetrates one of the round holes and is pulled out, a special wire rope tensioning tool is used to tension the wire rope after the adjustment, and then tightening, binding and fastening functions are achieved; and the rigging has the advantages of simple structure, convenient operation, low cost, high safety coefficients, and great reduction of transportation cost. The wire-rope unidirectional lock is suitable for binding and fastening woods, steels, machines and wheel-type equipment transported by rail.

Description

The unidirectional lock of steel rope

Technical field

The utility model relates to the binding of railway transportation goods and reinforces equipment, is that rigging is reinforced in a kind of novel binding, is applicable to that the binding of timber in the railway transportation, steel, mechanical equipment and wheeled equipment is reinforced.

Background technology

At present, the binding reinforcement material that China Railway present stage is adopted, based on wire rod and steel rope, the steel rope tension adopts ratchet-type tension or rack-and-pinion take-up device and wire clips to stick into steel rope, all has its unsatisfactory problem.All there are following defective in ratchet-type tension or rack-and-pinion take-up device: the ratchet-type tense wire rope is wrapped in thin axle and goes up destructible steel rope intensity, rack-and-pinion take-up device and wire clips inconvenient operation, and use cost is high and lock insecure; Wire rod is complicated operation in reinforcing process, twists when tight more seriously to the wire rod damage, and safety factor is low.

Summary of the invention

Shortcoming and defect for the binding reinforcement means that overcomes existing timber, steel, machinery and wheeled equipment, the utility model provides a kind of steel rope unidirectional lock, wherein unidirectional lock is alternative now with tension of steel rope ratchet-type and rack-and-pinion take-up device, is equipped with the special-purpose tensioning tool of reusable steel rope steel rope is strained; This rigging structure is simple, and is easy and simple to handle, and cost is low, and the safety factor height can reduce traffic cost greatly.

The technical scheme that its technical matters that solves the utility model adopts is: the unidirectional lock of a kind of steel rope is to be formed by connecting by unidirectional lock, steel rope and buckle; It is characterized in that, unidirectional lock inner slide, spring, bottom series connection, bottom is captiveed joint with housing, and compression spring can slide in housing when slide block was stressed; It is conical that wherein said housing one end is, and the other end is cylindrical, and there is a lug side, and a circular hole is arranged on the lug; It is conical that slide block is, and a round tube hole is axially arranged, and two-layer circular hole is radially arranged, and every layer of 3 of circular hole is distributed on the circumference and connects with axial circular hole, and steel ball is placed in the circular hole, and steel ball is rotatable in the hole.When restraint of loads, steel wire rope head passed unidirectional lock circular hole and pull out, adjust suitably after, with special steel wire rope tensioning tool steel rope is strained, thereby is played the effect that the tension binding is reinforced.The binding that is applicable to timber binding, steel, machinery and wheeled equipment in the railway transportation is reinforced.

The utility model has following actively useful effect:

1. unidirectional lock uses than now that the steel rope strainer is simple in structure, cost is low.

2. unidirectional lock is inner to adopt double-deck steel ball to block steel rope, and intensity strengthens, and does not damage steel rope.

3. unidirectional lock can guarantee that steel rope is unidirectional and pull out, tightly pin steel rope when retreating.

4. easy to operate, tensile strength is big, and is safe to use.

5. it is reusable to be equipped with the special-purpose tensioning tool of steel rope.

Description of drawings

Below in conjunction with accompanying drawing and specific implementation method the utility model is further described.

Fig. 1 is the structural representation of unidirectional lock;

Fig. 2 is the slide block structure scheme drawing;

Fig. 3 is Fig. 2 A-A section-drawing;

Fig. 4 is Fig. 2 B-B section-drawing;

Among the figure: 1, unidirectional lock,, 2, steel rope, 3, buckle; 01. housing, 02. bottom, 03. spring, 04. slide block, 5. steel ball A, 6. steel ball B.

The specific embodiment

In Fig. 1, Fig. 2, it is conical that housing one end is, and the other end is cylindrical, and there is a lug side, and a circular hole is arranged on the lug; It is conical that slide block is, and a round tube hole is axially arranged, and two-layer circular hole is radially arranged, and every layer of 3 of circular hole is distributed on the circumference with axial circular hole and connects, and steel ball is placed on radially in the circular hole, and steel ball is rotatable in the hole.

In Fig. 5, the unidirectional lock of steel rope is formed by connecting by unidirectional lock, steel rope and buckle; When restraint of loads, steel wire rope head passed unidirectional lock circular hole and pull out, adjust suitably after, with special steel wire rope tensioning tool steel rope is strained, thereby is played the effect that the tension binding is reinforced.The binding that is applicable to timber binding, steel, machinery and wheeled equipment in the railway transportation is reinforced.

Claims
