Abstract

Disclosed is a unidirectional self-locking strainer which is a new binding fastening rigging, relating to a binding fastener used in railway freight transportation. The unidirectional self-locking strainer consists of a strainer and a wire cable which are connected, and the components of the unidirectional self-locking strainer are mechanically punched and riveted. The strainer is connected by two symmetric scaffold boards through a ratchet wheel shaft, a detent shaft and a riveting pin; a ratchet wheel is fixed on the ratchet wheel shaft; a detent is hitched on the ratchet wheel shaft and is matched with the ratchet wheel; a retainer ring is fixed on the ratchet wheel shaft through a fixing pin; a spring is installed inside the detent and is hitched on the detent shaft; one end of the wire cable is threaded through the riveting pin and is fixedly connected through a wire cable buckle and the other end is inserted into a wire cable slot on the ratchet wheel shaft; the head of the wire cable threads out from the end of the ratchet wheel shaft; tightness degree of the wire cable is adjusted; a rotary hand lever is inserted into a rotary hand lever slot to rotate the ratchet wheel shaft to strain the wire cable; in this way, the unidirectional self-locking strainer can have the functions of straining and binding. The self-locking strainer is suitable for integral combining of timbers and binding and fastening of rolled steel, machines and wheeled equipment.

Description

The unidirectional self-lock 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 the whole binding of timber, steel, machinery and wheeled equipment in the railway transportation is reinforced.

Background technology

At present, in the middle of the China Railway industry, have Φ 6mm or the binding of Φ 6.5mm wire rod that the integral body of lumber Transporting binding reinforcing aspect generally adopts are reinforced; It is fastening mostly to adopt steel rope to block with wire clips to the binding reinforcing of steel, machinery and wheeled equipment, complicated operation, waste of material is serious, traffic cost is high, 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 the binding reinforcement means that has the whole binding of timber, steel, machinery and wheeled equipment now, the utility model provides a kind of unidirectional self-lock strainer, 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 matters that solves the utility model adopts is: a kind of unidirectional self-lock strainer is to be formed by connecting by strainer, steel rope, and its parts adopt the mechanical stamping riveted; Its special character is, described strainer is connected by ratchet shaft, pawl axis, riveting pin by two symmetrical frame plates, and ratchet is fixed on the ratchet shaft, and ratchet shaft axially is a round tube hole, one rotation hand thick stick socket is radially arranged, and central side has a long shape hole and axially round tube hole perforation; Ratchet is enclosed within on the pawl axis and is used with ratchet, and baffle ring is fixed on the ratchet shaft with set pin, 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; Steel rope one end passes riveting pin steel rope buckle captive joint, other end steel rope inserts the steel rope socket on the ratchet shaft, steel wire rope head passes from the ratchet shaft end, adjust steel rope degree of tightness appropriateness, rotation hand thick stick inserts rotation hand thick stick socket rotating ratchet axle tense wire rope, thereby plays the effect that the tension binding is reinforced.The binding that is applicable to the whole binding of timber, steel, machinery and wheeled equipment in the railway transportation is reinforced.

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 the strainer structural representations of unidirectional self-lock strainer;

Fig. 3 is a unidirectional self-lock strainer structural representation;

Fig. 4 is a unidirectional self-lock strainer example structure scheme drawing.

Among the figure: 01, strainer;

1. frame plate, 2. ratchet, 3. ratchet shaft, 4. ratchet, 5. pawl axis, 6. riveting pin, 7. set pin, 8. baffle ring, 9. steel rope jack, 10. rotation hand thick stick socket, 11. springs, 12. steel ropes, 13. steel rope buckles.

The specific embodiment

In Fig. 1, Fig. 2, 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), ratchet shaft (3) axially is a round tube hole, one rotation hand thick stick socket (9) is radially arranged, and central side has a long shape hole and axially round tube hole perforation; Ratchet (4) is enclosed within on the pawl axis and is used with ratchet, and baffle ring (8) is fixed on the ratchet shaft with set pin (7), and spring (11) is installed in the ratchet internal sleeve on pawl axis, and two frame plates of riveting pin (7) riveted joint axially are through hole;

In Fig. 3, steel rope (12) one ends pass riveting pin (6) hole steel rope buckle (13) captive joint of strainer (01).

In the embodiment of Fig. 4 institute, steel rope (12) one ends pass riveting pin (6) hole steel rope buckle (13) captive joint of strainer (01); Other end steel rope inserts the steel rope socket (10) on the ratchet shaft, steel rope (12) head passes from the ratchet shaft end, adjust steel rope degree of tightness appropriateness, rotation hand thick stick inserts rotation hand thick stick socket (9) rotating ratchet axle tense wire rope, thereby plays the effect that the tension binding is reinforced.

Claims
