Abstract

The utility model relates to a cable wire strainer for fixing cargos transported by railways, which is designed for increasing the locking and fastening ability of a movable end of a cable wire. The structure is that a support shaft is connected between two opposite clamping straps, a ratchet wheel fastening mechanism is installed on one end between the two clamping straps, and a wedge sleeve is fixed on the other end thereof through a cross-under pin, a wedge iron is arranged in the wedge sleeve, a chute arranged on the middle portion of the wedge iron is sleeved on the pin for fixing the wedge sleeve. The cable wire strainer changes the structure of the clamping strap combined end of an original strainer, facilitates the gap between the wedge sleeve and the wedge iron and a cross-under cable wire to form the surface contact, thereby greatly increasing the locking and fastening ability of the strainer for the movable end of the cable wire, reaching the technical standard requirements, effectively reducing or eliminating the steel wire loosening phenomenon, and enormously increasing the safety of cargo transportation.

Description

A kind of strainer

Technical field

The utility model relates to the equipment that is used for fixing shipping goods in a kind of rolling stock, specifically a kind of strainer.

Technical background

In the railway cargo loading process reinforcing process, use a kind of steel-wire fastener at present more.This fastener is to be connected to pivot shaft between two relative clamping plate, and the ratchet fastening device is installed in the end between two clamping plate, and the other end of clamping plate is a binding end, promptly rivets together mutually by rivet on the edge that turns up.At the embedded slidably drift that is connected to of clamping plate binding end, promptly have chute at the plate face middle part of two clamping plate, the bearing pin cross-under is arranged on the drift in chute.This fastener is to cooperate single wire rope to use, because the steel rope movable end is to be locked on the fastener by clamping plate binding end and cooperating of drift, and the flanging riveted connection structure of clamping plate binding end, make its inboard constitute fin, like this, just constitute that a kind of line contacts but not the face contact with the steel rope of cross-under, this just makes the clamping plate binding end limited to the locking fastening ability of steel rope.Therefore, in actual use, the get loose generation of phenomenon of fastener clamping plate binding end and steel rope is just arranged, the safety of goods transport is had a negative impact.

The utility model content

The purpose of this utility model just provides the strainer that a kind of fixedly railway transportation goods is used, to improve the locking fastening ability of securing device to the steel rope movable end, the safety that improves goods transport.

The utility model is achieved in that the strainer that a kind of fixedly railway transportation goods is used, between two relative clamping plate, be connected to pivot shaft, the ratchet fastening device is contained in the end between two clamping plate, institute's improvements are in the other end of the clamping plate dowel fixes by cross-under cover of wedge to be arranged, be provided with drift in the cover of wedge, the chute that drift middle part is offered is socketed on the pin of fixing cover of wedge.

The utility model has changed the structure of the clamping plate binding end of original fastener, by pin clamping plate and cover of wedge is fixed together, and the drift slidably of cross-under therein.Like this, the steel rope movable end is exactly by staying seam to be locked on the strainer cooperating between cross-under cover of wedge and drift, contact and the inboard of cover of wedge just can form a kind of with the steel rope of cross-under, this just makes strainer that the locking fastening ability of steel rope movable end is greatly improved.Thereby just can reduce even avoid the get loose generation of phenomenon of steel rope effectively, and satisfy the technical requirements of " railway cargo loading process is reinforced rule ", the safety of goods transport is greatly improved.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

The specific embodiment

As shown in Figure 1 and Figure 2, this novel strainer has two relative clamping plate 4, is connected to pivot shaft 11 between two clamping plate, is connected to two ratchets 7 and socket torsion spring 5 on pivot shaft 11, and the stage casing of torsion spring is not on spring axle 6; Ratchet 8 is contained on the ratchet shaft between two clamping plate, and the overhanging end of ratchet shaft is a quadrat sampling plate axle 10.Torsion spring 5, spring axle 6, ratchet 7, ratchet 8 and ratchet shaft are formed the ratchet fastening device.In the riveted joint of the left end of clamping plate 4 by pin 2, two clamping plate 4 and middle cover of wedge 1 are fixed together, have chute on the drift 3 in cover of wedge, pin 2 is socketed on the drift chute, and drift can be reciprocatingly slided.

As shown in Figure 2, the longitudinal axis cross section of cover of wedge 1 is taper type, its both ends open, and hypotenuse is the faying face that cooperates with drift up and down.Drift 3 is and the cooresponding tabular bullet of cover of wedge 1 shape.The movable end of steel rope penetrates from staying between seam of a side between cover of wedge 1 and the drift 3, after the trailing edge of walking around drift 3, stays between seam from the opposite side between cover of wedge 1 and the drift 3 to pass.Two external parts of tense wire rope can compress and lock the movable end of steel rope by moving to left of drift 3.

The lateral cross section of cover of wedge 1 is court runway shape (not shown), and promptly two medial surfaces contacting with steel rope of cover of wedge are circular arc, so again with the peripheral edge of drift 3 along being made for cancave cambered surface.So just can make between cover of wedge 1 and the drift 3 two of constituting stay to be seamed into and be rotund passage.Can make the contact surface of the two and steel rope reach maximum like this, the locking fastening ability is the highest.

The utility model is still a kind of steel rope take-up device that cooperates single wire rope to use, still cross-under and be fastened with steel cable on the ratchet shaft 9 of strainer, after twining goods with steel rope, the drift 3 that its movable end is walked around in the cover of wedge 1 is locked, rotate the quadrat sampling plate axle 10 of ratchet shaft outer end then with spanner, steel rope can be strained, reach the purpose of fastening goods.

Claims

1, the strainer used of a kind of fixedly railway transportation goods, between two relative clamping plate (4), be connected to pivot shaft (11), the ratchet fastening device is contained in the end between two clamping plate, it is characterized in that being fixed with cover of wedge (1) at the other end of the clamping plate pin (2) by cross-under, be provided with drift (3) in the cover of wedge, the chute that drift (3) middle part is offered is socketed in fixedly on the pin of cover of wedge (2).

2, strainer according to claim 1 is characterized in that the longitudinal axis cross section of cover of wedge (1) is taper type, and drift (3) is and the cooresponding tabular bullet of cover of wedge (1).
