Description
Technical field
The utility model relates to hoisting sling, particularly relates to a kind of perpendicular perpendicular volume of the two hinges of keying rod-type tongs that hangs the steel plate coiled material.
Background technology
The rolling coil of strip erects the heavy suspender of slinging and is single hinge or two hinge bar linkage structure at present, and its single hinge suspender is for guaranteeing to have enough gripping powers, and necessary lengthening arm bar causes the volume of hoisting sling big, and weight is big, and it is unfavorable to cause for the carrying transportation.Mostly two hinge suspenders are round steel, square steel steel billet suspender, and its suspender start-stop system is for the gravity on-off structure or adopt electronic and the keying of fluid control suspender, complex structure, manufacturing cost is high, and suspender is lower service life.
The utility model content
The technical matters that the utility model will solve, it is little, in light weight, easy to operate to provide a kind of volume, can realize that machinery opens and closes, the perpendicular volume of the two hinges of the keying rod-type of lifting tongs.
The technical scheme that adopts is:
The perpendicular volume of the two hinges of a kind of keying rod-type tongs comprises tongs pinch, tongs clamp arm, goes up torque arm, support fixation connecting panel, hanger, messenger, keying strut.Described tongs clamp arm is that the intersection symmetry is laid about two; Said support fixation connecting panel is two symmetry layings before and after the tongs clamp arm; Front and back support fixation connecting panel lower edge is welded with bottom plate and constitutes integrative-structure; The right ends of support fixation connecting panel is hinged through the tongs clamp arm of a pair of hinge and the left and right sides, and as arm of force fulcrum, the afterbody of two tongs clamp arms is connected with last torque arm lower end by adapter shaft; As the point of application, last torque arm top is connected with hanger through the hanger adapter shaft.Said tongs pinch is connected with the head of tongs clamp arm through the pinch adapter shaft, and the tongs pinch can rotate in the angle of setting.Said hanger top is provided with messenger, and messenger is fixed on the hanger through hanging axis.Said keying strut is fixed on set pin in the last torque arm in left side with tail end, and the recess set with head overlaps on the keying locating dowel pin that torque arm on the right side sets firmly.
Above-mentioned keying strut downside is arc surfaced, opens and closes the strut head and is provided with a recess, establishes a rectangular cavity in the notch portion, and the open-close on-off of flaabellum shape is housed in the cavity, is connected with the open-close on-off anchor shaft to open and close on the strut.
In the above-mentioned tongs clamp arm, be in the inboard tongs clamp arm lateral surface boundary position that intersects, the positive stop of wigwag motion assymmetrical deformation when front and back respectively are welded with stretching, extension of control caliper or contraction.
The utility model has adopted two hinges, and the fulcrum hinge of two main force's tongs clamp arms is separately positioned on the opposite side of caliper, makes caliper clamp arm of force lengthening; The caliper compact overall structure; Volume is little, in light weight, and the clamping degree of depth is big, and hoisting capacity and safety factor are greatly enhanced; Hoisting and hanging is flexible to operation, and is safe and reliable.

The specific embodiment
The perpendicular volume of the two hinges of a kind of keying rod-type tongs comprises tongs pinch 1, tongs clamp arm 3, upward torque arm 7, support fixation connecting panel 5, hanger 11, messenger 17, opens and closes strut 9.Described tongs clamp arm 3 is that the intersection symmetry is laid about two; Said support fixation connecting panel 5 is two symmetry layings in tongs clamp arm 3 front and back; Front and back support fixation connecting panel lower edge is welded with bottom plate 16 and constitutes integrative-structures; The right ends of support fixation connecting panel 5 is hinged with the tongs clamp arm 3 of the left and right sides through a pair of hinge 4, and as arm of force fulcrum, the afterbody of two tongs clamp arms is connected with last torque arm 7 lower ends by adapter shaft 6; As the point of application, last torque arm 7 tops are connected with hanger 11 through hanger adapter shaft 10.Said tongs pinch 1 is connected with the head of tongs clamp arm 3 through pinch adapter shaft 2, and tongs pinch 1 can rotate in the angle of setting.Said hanger 11 tops are provided with messenger 17, and messenger 17 is fixed on the hanger 11 through hanging axis 18.Said keying strut 9 downsides are arc surfaced; Open and close the strut head and be provided with a recess; Establish a rectangular cavity (see figure 1) in the notch portion, the open-close on-off 12 of flaabellum shape is housed in the cavity, be connected on the keying strut 9 with open-close on-off anchor shaft 13; Be fixed in the last torque arm 7 in left side to open and close strut tail end set pin 8, the recess set with head overlaps on the keying locating dowel pin 14 that torque arm on the right side sets firmly.In the said front and back tongs clamp arm 3; Be in the inboard tongs clamp arm lateral surface boundary position that intersects; Front and back respectively are welded with positive stop 15; Be in the clamp arm that the outside intersects in order to block, wigwag motion assymmetrical deformation when the control caliper stretches or shrinks, the perpendicular volume of the two hinges of a kind of keying rod-type of said formation tongs.
Principle of work
The utility model opens and closes locating dowel pin 14 and is stuck in keying strut 9 recesses before unlatching, and open-close on-off 12 is removed, and tongs is lock-out state.During hoisting heavy; Bottom plate 16 below the tongs clamp arm support fixation connecting panel 5 has at first contacted weight, connecting rod mechanism generation interlock, and last torque arm pulling opens and closes strut and is moved to the left; Keying strut recess is skidded off from opening and closing locating dowel pin 14, and open-close on-off 12 falls to sealing to open and close the strut recesses; When tongs was sling, tongs prolonged vertical direction and stretches, and last torque arm promotes to open and close strut and moves right; When opening and closing locating dowel pin 14 through keying strut recess process; Open and close the strut recess because open-close on-off 12 has been sealed, open and close locating dowel pin 14 and can't get into recess, start and stop lever can not be lockable.After the pliers closure, the generation friction force between clamping clip pin and the weight links tongs, produces gripping power through lever, will play weight and clamp.
