Abstract

A self-locking strainer for a steel wire rope relates to a binding and reinforcing device for cargos conveyed in railway, is a novel binding and reinforcing cable, and is formed by connecting a unidirectional self-locking strainer and a steel wire rope, and the components are riveted by mechanical punching. For the strainer, two symmetrical frame plates are connected by a ratchet shaft, a pawl shaft and a riveting pin, a ratchet wheel is fixed on the ratchet wheel shaft, a pawl is sheathed on the pawl shaft and is matched with the ratchet wheel for use, and a spring is installed at the inner part of the pawl and sheathed on the ratchet shaft; one end of the steel wire rope penetrates through the riveting pin and is fixedly connected with an aluminum alloy pressing joint, the other end of the steel wire rope is inserted into a steel wire rope jack in the ratchet shaft, the steel wire rope head extends out of the end part of the ratchet shaft, and the looseness of the steel wire rope is adjusted to be proper, and a rotating force applying shaft drives the ratchet shaft to rotate so as to strain the steel wire rope, thus playing the roles of straining, binding and reinforcing. The self-locking strainer for the steel wire rope is applicable to binding and reinforcing steel materials and mechanical and wheel type devices in the railway transportation.

Description

Steel wire rope self-locking strainer

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 steel in the railway transportation, machinery and wheeled equipment is reinforced.

Background technology

At present, in the middle of the China Railway industry, what the binding reinforcing aspect that steel are transported generally adopted has Φ 6mm or Φ 6.5mm wire rod or adopts steel wire rope to join wire clips binding reinforcing, complicated operation, waste of material are serious, loading and unloading are on-the-spot disorderly and unsystematic, and stability is subjected to effect of inertia in transit and changes, very easily the generation binding is become flexible and can't be fastening, buries many potential safety hazards.

Summary of the invention

In order to overcome the shortcoming and defect of existing steel binding reinforcement means, the utility model provides a kind of steel wire rope self-locking strainer, and this binding rigging is not only simple to operate, economical and practical, and easy to use, convenient power-saving, safe and reliable.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of steel wire rope self-locking strainer is to be formed by connecting by steel unidirectional self-lock strainer, steel wire rope, and its parts adopt the mechanical stamping riveted; It is characterized in that described unidirectional self-lock strainer is connected by ratchet shaft, pawl axis, riveting pin by two symmetrical frame plates, ratchet is fixed on the ratchet shaft, and ratchet shaft axially is a round tube hole, and there are a long shape hole and axially round tube hole perforation in the center; Adding mechanical axis is placed in the ratchet shaft and can rotates; Ratchet is enclosed within on the pawl axis and is used with ratchet, and spring is installed in the ratchet internal sleeve on pawl axis, and two frame plates of riveting pin riveted joint axially are through hole.It is fixedly connected with aluminium alloy compacting joint that steel wire rope one end passes riveting pin, other end steel wire rope inserts the steel wire rope jack on the ratchet shaft, steel wire rope head passes from the ratchet shaft end, adjust steel wire rope degree of tightness appropriateness, rotation adds mechanical axis makes ratchet shaft rotate tense wire rope, thereby plays the effect that the tension binding is reinforced.Be applicable to that the binding to steel, machinery and wheeled equipment is reinforced in the railway transportation.

The utility model has following actively useful effect:

1, adopt the mode of rotating ratchet to strain also locked, simple to operate;

2, simple in structure, easy to use, intensity is high, safe and reliable.

Description of drawings

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

Fig. 1, Fig. 2 are unidirectional self-lock strainer structural representations;

Fig. 3 is a steel wire rope self-locking strainer structural representation;

Fig. 4 is a steel wire rope self-locking strainer example structure schematic diagram.

Among the figure: 01, unidirectional self-lock strainer;

1. frame plate, 2. ratchet, 3. ratchet shaft, 4. ratchet, 5. pawl axis, 6. riveting pin 7. adds mechanical axis, 8. steel wire rope jack, 9. spring, 10. steel wire rope, 11. aluminium alloys compacting joint.

The specific embodiment

In Fig. 1, Fig. 2, the unidirectional self-lock strainer is connected by ratchet shaft (3), pawl axis (5), riveting pin (6) by two symmetrical frame plates (1), ratchet (2) is fixed on the ratchet shaft (3), and ratchet shaft (3) axially is a round tube hole, and there are a long shape hole and axially round tube hole perforation in the center; Ratchet (4) is enclosed within on the pawl axis and is used with ratchet, and spring (9) is installed in the ratchet internal sleeve on pawl axis, and two frame plates of riveting pin (6) riveted joint axially are through hole;

In Fig. 3, it is fixedly connected that joint (11) is suppressed with aluminium alloy in the riveting pin hole that steel wire rope (10) one ends pass unidirectional self-lock strainer (01).

In Fig. 4 embodiment, it is fixedly connected that joint (11) is suppressed with aluminium alloy in the riveting pin hole that steel wire rope (10) one ends pass strainer (01); Other end steel wire rope inserts the steel wire rope jack (8) on the ratchet shaft, steel wire rope (10) head passes from the ratchet shaft end, adjust steel wire rope degree of tightness appropriateness, add mechanical axis (7) with the lease rods rotation and make ratchet shaft rotate tense wire rope, thereby play the effect that the tension binding is reinforced.
