Abstract
The utility model relates to device for reinforcing when railway open flat wagons load coil steel, in particular to a steel traction tightener. The steel traction tightener comprises a square steel cross arm, traction bars and a steel wire rope, two ends of the square steel cross arm are respectively provided with the traction bars through through holes in the square steel cross arm, wherein one end of each traction bar is provided with screw thread while the other end is provided with a pull ring, the screw thread end of each traction bar is provided with a screwing nut while the pull ring end is connected with the steel wire rope, traction protecting plates made of angle steel are respectively fixedly welded on the square steel cross arm on the inner sides of the two traction bars, and the space between the two traction protecting plates is longer than the shielded length and the width of a coil steel plate. Compared with existing steel wire ropes and steel wire rods, the steel traction tightener has the advantages of compact contact surfaces of coil steel, the barrier and a coil center, fine stability, balanced traction force, strong anti-impact pull force and the like, has functions of correcting goods so as to prevent lateral deviation of the goods due to adjustment of the screw thread of the traction bars and actions of balance resistance of the square steel cross arm and the traction protecting plates, and resolves problems that the pulling end of the steel wire rope is easy to be laterally shifted in traction and the steel wire rope is easy to be broken when coiled, fastened and drawn.
Description
Technical field:
When the utility model relates to the spacious flatcar shipment coil of railway (band steel), play the device of reinforcement effect, especially a kind of steel tractive fastener.
Background technology:
At present, the spacious flatcar of railway generally adopts steel rope or wire rod to reinforce when shipment coil (band steel) goods.Adopting steel rope (or steel-wire fastener) reinforcement means is that the coil (band steel) that steel rope (or steel-wire fastener) passes the dress that crouches is covered anti-word tractive again of grade pulling rope retaining ring pocket head or the volume heart.The shortcoming of this method is: steel rope and steel and cover a grade edge and formed knuckle and direct friction, and when meeting greater impact power, steel rope is easy to break, and this problem is common generation in current programme.Adopting the wire rod reinforcement means can reduce the problem that fractures takes place, waste time and energy but use, not only need in advance with the stretching shearing of wire rod, and when beating Invited-for owing to misoperation, dynamics differ, also can cause the firmly uneven problem of each burst of wire rod, have a strong impact on loading speed and loading safety.
Summary of the invention:
The utility model is intended to solve the goods that the spacious flatcar of present railway exists and reinforces problem when shipment coil (band steel) goods, and provide that a kind of shock resistance pulling force is strong, tuningout proofreaies and correct that goods spare is easy, traction force is balanced, fastening effective, anti-lateral deviation effect, tractive fastener esy to use, safe and reliable arranged.
The technical scheme that the described problem that solves the utility model adopts is: a kind of steel tractive fastener, comprise square steel cross-arm, tractive rod, steel rope, the tractive rod of an end band screw thread other end band draw ring is equipped with at its two ends of described square steel cross-arm respectively by through hole on it, the screw thread end of this tractive rod is equipped with and screws nut, and the draw ring end connects steel rope; On the inboard square steel cross-arm of described two tractives rod respectively solid welding the tractive backplate of being made by angle steel is arranged, cover grade length and the coil plate is wide apart from being longer than between the two tractive backplates.
The utility model is reinforced with existing steel rope (steel-wire fastener) and wire rod and is compared, it has with coil (steel band), covers characteristics such as grade body and volume heart contact surface compactness, good stability, traction force equilibrium, shock resistance pulling force are strong, and, preferably resolve the easy sidesway of steel rope pocket head tractive, roll up the problem that the fastening tractive of the heart easily breaks owing to the balance resistance and the effect of tractive backplate of screw thread adjusting of tractive rod and square steel cross-arm makes this fastener have the anti-lateral deviation function of the goods spare of correction.The fastening use of the coil (band steel) of all size of its particularly suitable dress for sleeping in, easy and simple to handle, can reduce labour intensity effectively, the compression production time improves conveying efficiency.Can two during the fastening coil of tractive (band steel) or two above goods be one group, cover grade base pocket head or the fastening tractive of the volume heart.This product is reusable under the not impaired situation of each parts, and the cost cost is low, is easy to the user and accepts.
Description of drawings:
Structural representation when Fig. 1 covers retaining for the utility model is used for tractive iron.
Structural representation when Fig. 2 is used to roll up heart tractive for the utility model.
Fig. 3 is the utility model running condition scheme drawing.
Among the figure: square steel cross-arm 1, buffering abrasionproof line rubber cushion 2 screws nut 3, and tractive backplate 4, tractive rod 5, draw ring 6, steel rope 7, coil 8, iron are covered retaining 9, and iron is covered retaining tractive fastener 10, and T-magnet 11 at the bottom of the car, volume heart tractive fastener 12.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, the described steel tractive of present embodiment fastener, the two ends of its square steel cross-arm 1 are respectively arranged with through hole, the tractive rod 5 of one end band screw thread other end band draw ring 6 is housed in this through hole, the screw thread end of this tractive rod 5 is equipped with and screws nut 3, draw ring 6 ends connect on the square steel cross-arm 1 of steel rope 7, two tractives rod 5 inboards solid welding respectively to be had between tractive backplate 4, the two tractive backplates of being made by angle steel 4 apart from being longer than and covers grade length and the coil plate is wide.
Referring to Fig. 3, the utility model can be used for tractive iron and covers retaining 9, also can be used for rolling up heart tractive coil 8.Be used for tractive iron and cover retaining 9 o'clock, tractive backplate 4 its bases that iron is covered retaining tractive fastener 10 grow the width (as shown in Figure 1) of square steel cross-arm 1 and cover retaining 9 bases with long with iron, and with this tractive bracing frame as square steel cross-arm 1; When being used to roll up heart tractive coil 8, tractive backplate 4 its length identical with square steel cross-arm 1 width (as shown in Figure 2) of volume heart tractive fastener 12.
During practical application, the materials of described square steel cross-arm 1, tractive rod 5 and steel rope 7 and rupture pull force should be in advance according to the diameter of coil 8 with plate is wide, volume heavily comes to determine, be equipped with on the square steel cross-arm 1 of described tractive backplate 4 inboards to cushion abrasionproof line rubber cushion 2.Used steel rope 7 passes the draw ring 6 usefulness ply-yarn drills or the gland locking of tractive rod 5, and fasten on T-magnet at the bottom of the car 11 other end, fastening by screwing nut 3.
