Embodiment

In order to further illustrate technical scheme, in conjunction with the embodiment of the brief description of the drawings present invention；Such as The high strength steel of 10 millimeters commercially available of thickness is selected in Fig. 3, this example, " C " font conduct of long 40 millimeters of 420 mm wide is cut into Hook arm 21, its upper end is bows out to the right 60 millimeters of semi arch, and a diameter of 40 millimeters of the semi arch, its middle part is provided with a water The flat projection for stretching out 28 millimeters to the right, the projection is the semicircle arcuation of 25 millimeters of diameter, and its lower end is center of circle deviation right side Irregular circular arc, a diameter of 95 millimeters of the irregular circular arc；Selected in this example and one and diameter are set in the upper end of hook arm 21 24 millimeters of through hole is as upper through hole 23, and upper through hole 23 and the upper end of hook arm 21 are concentric；Select convex at the middle part of hook arm 21 in this example Set the through hole of 16 millimeters of a diameter as lower through-hole 24 on block, lower through-hole 24 and projection are concentric；Selected in this example in hook arm Lower end sets the U-shaped breach of a right opening as breach 25, and 70 millimeters of the length of breach 25 is high 25 millimeters；Select and lacking in this example Set a rectangle plane as working face 26 on the bottom surface of mouth 25,58 millimeters of the length of working face 26 is wide 10 millimeters, with upper through hole 23 Diameter parallel；The high strength steel of 10 millimeters commercially available of thickness is selected in this example, long 60 millimeters, wide 40 millimeters of plate is cut into Shape, is used as floor 22；The quantity for the hook arm 21 selected in this example is two, and 60 millimeters of spacing is arranged in parallel；Selected in this example The quantity of floor 22 be two, two floors 22 are placed between two hook arm 21, floor 22 vertically with hook arm 21, its In floor 22 be located at hook arm top, another floor 22 is located at hook arm bottom, by the two ends of two floors 22 respectively with one Hook arm 21 welds together；This completes the implementation of hook.

Such as Fig. 4, the round steel of 40 millimeters commercially available of diameter is selected in this example, 50 millimeters of length is chosen, as cylindrical section 31, The middle part of cylindrical section 31 sets the through hole of a diameter 20 millimeter vertical with its axis, and one is respectively set at the two ends of arc section 31 24 millimeters of diameter, deep 12 millimeters blind hole sets M24 internal thread on blind hole inwall；It is 30 millimeters that length is selected in this example With the externally threaded bolts of M24 as bolt 32, the quantity in this example from bolt 32 is two；This completes be hinged The implementation of part.

The high strength steel of 10 millimeters commercially available of thickness is selected in such as Fig. 5, this example, 106 millimeters of length, the milli of width 60 is chosen Rice, will one 50 millimeters of length of cutting in the middle part of its one end, the breach that 40 millimeters of width, using this U-shaped steel plate as tightening up plate 51, The openend for tightening up plate 51 sets hinge hole match with connecting shaft 52, in the case where tightening up the closed end setting and hook of plate 51 The hinge hole that through hole matches；In this example select 90 millimeters commercially available of length, the straight pin that 16 millimeters of diameter as connecting shaft 52, Respectively there is a jump ring at the two ends of connecting shaft 52；From the quantity of plate 51 is tightened up for two in this example, it is hinged by connecting shaft 52； This completes the implementation of take-up.

The steel wire rope of 10 millimeters commercially available of diameter is selected in such as Fig. 2, this example, 1500 millimeters of length is chosen and is used as connection member 4；Quantity in this example from hook 2 is 2, by two direction relative orientation disposed inboards of hook 2；By the circle of hinge member 3 Shell of column 31 is placed between two hooks 2, the bolt 32 of hinge member 3 is sequentially passed through to the upper through hole 23 of two hooks 2, then In the tapped blind hole for screwing in cylindrical section 31, so that two hooks 2 be hinged；From the connection with take-up 5 in this example The mutually isostructural axle of axle 52, the lower through-hole 24 the closed end for tightening up plate 51 of take-up 5 respectively with a hook 2 is hinged on one Rise；The lower end of connection member 4 is passed through from the through hole at the middle part of cylindrical section 31 of hinge member 3, plate is tightened up through take-up 5 51 breach at the middle part of connecting shaft 52, enclose by least winding one, then knots, so that connection member 4 and take-up 5 are connected to Together；The epimere of connection member 4, which is knotted, turns into annular shape, can avoid connection member 4 from the cylindrical section 31 of hinge member 3 Slide, also facilitate the suspension hook with driving or crane to be connected；This completes the implementation of the present invention.

In such as Fig. 1, this example trailer crossbeam 6 is used as from the general gooseneck trailer crossbeam of the industry；Risen using the present invention When hanging crossbeam 6, on the suspension hook that the annulus of the epimere of connection member 4 is first hung over to driving or crane, then by two hooks 2 The upper flange both sides at the middle part of trailer crossbeam 1 are hooked in, breach 25 is caught in wing plate from wing plate both sides, make working face 26 and upper flange Lower surface is in contact；When suspension hook is pulled up, connection member 4 pulls up tightening device 5, and tightening device 5 is inside by hook 2 Side is tightened up, so that breach 25 tightly blocks wing plate both sides；Labor intensity is low, and operating efficiency is high, reduces potential safety hazard.
