The specific embodiment
As shown in Figures 1 to 4, the utility model comprises base 1 for the structure of taking root of the maintenance safety strap of grabbing bucket, vertical rod 2, the ring 3 and bearing pin 5 of taking root, described base 1 is provided with hugging 13 vertically, described vertical rod 2 bottoms and described base 1 one end are hinged, the described ring 3 of taking root is located at described vertical rod 2 tops, described base 1 meets at right angles and is respectively equipped with horizontal pin-and-hole 11 and vertical pin-and-hole 12 along hinge-point A, described vertical rod 2 bottoms are provided with fixed pin holes 21, the location matches of described fixed pin holes 21 positions and described horizontal pin-and-hole 11 and vertical pin-and-hole 12, described vertical rod 2 is lying in the hugging 13 of described base 1 when interior along hinge-point A rotation, described bearing pin 5 is located in the horizontal pin-and-hole 11 of described base 1 and the fixed pin holes 21 of vertical rod 2, when described vertical rod 2 is rotated perpendicular to described base 1 along hinge-point A, described bearing pin 5 is located in the vertical pin-and-hole 12 of described base 1 and the fixed pin holes 21 of vertical rod 2, described base 1 is located at grab bucket end face.
Further, above-mentioned horizontal pin-and-hole 11, vertical pin-and-hole 12 and fixed pin holes 21 are boss shapes, described bearing pin 5 tail ends are provided with handle 51, nose circle side face is provided with projection 52, and the shape of described projection 52 is mated with the boss shape of described horizontal pin-and-hole 11, vertical pin-and-hole 12 and fixed pin holes 21.
Further, the structure of originally taking root also comprises four floors 4, and described four floors 4 are located at interval at respectively described base 1 both sides and connect described base 1 and grab bucket end face.
Further, the structure of originally taking root also comprises two packing rings 6, and described two packing rings 6 are located at respectively the hinge-point A both sides of described vertical rod 2.
Originally the structure of taking root is arranged at the position at grab bucket top, adopt electric welding that base and four floors is firm with grab bucket welded top, service personnel carries out before upkeep operation at grab bucket top, bearing pin is passed through to the certain angle of rotatable handle, make the horizontal pin-and-hole of projection aligning on bearing pin and the boss of fixed pin holes, bearing pin can be exited in horizontal pin-and-hole and fixed pin holes, then by vertical rod from the hugging of base along hinge-point half-twist, bearing pin is inserted to locking in vertical pin-and-hole and fixed pin holes and after rotating to an angle, and upright position is reliably fixed in now vertical rod.Service personnel can carry out safety inspection operation after the clasp of safety strap is connected with the ring of taking root of rod end, and arranging of this safety strap meets high using priciple of hanging low use.When service personnel after top carries out upkeep operation, carries out reverse operating by bearing pin in grab bucket, vertical rod can be placed in the hugging of base and by bearing pin, vertical rod be locked, buckle for safety belts breaks off relations with the ring of taking root the most at last, so completes upkeep operation one time.
Originally the structure of taking root is installed on grab bucket tip position should consider the easy to use of service personnel, the operating position that the personnel that consider again stand, and be difficult for by steel wire rope of grab bucket grazing.By vertical rod and base hinged, met the height that safety strap takes root and be convenient to collection, when vertical rod is concealed in and has avoided grab bucket work in the hugging of base and the grazing of ship unloaders or steel rope, having guaranteed the safety of the structure of originally taking root.Originally the structure fabrication of taking root processing is simple, and practicality easy to use is firm, and the job safety of the service personnel at the top of can guaranteeing to grab bucket, can meet again the high principle of hanging low use of safety strap.
