Abstract

The utility model relates to a lifting appliance for a cylindrical workpiece and a barrel-shaped workpiece. The lifting appliance comprises at least two parallel lifting appliance branches. Each lifting appliance branch comprises two connecting plates, a limiting plate and two lifting hook plates, wherein the upper ends of the two connecting plates are hinged through an upper hinge pin; the lower ends of the two connecting plates are respectively hinged with the upper ends of the two lifting hook plates through a first middle hinge pin and a second middle hinge pin; the middle upper parts of the two lifting hook plates are hinged through a lower hinge pin; the limiting plate is arranged between the first middle hinge pin and the second middle hinge pin; and the lower parts of the two lifting hook plates are bent in a circular arc shape. The lifting appliance works by adopting a lever principle. The opening and folding of the lifting appliance are realized by utilizing the dead weights of the connecting plates and the lifting hook plates. When the lifting appliance is laid down along with hoisting equipment, the lifting hook plates can be opened under the action of the gravities of the connecting plates so as to conveniently carry out clamping work. When the lifting appliance is lifted up along with the hoisting equipment, the lifting hook plates are folded under the action of the gravities to clamp the cylindrical part between the two lifting hook plates so as to conveniently hoist. The lifting hook plates are prevented form intersecting by the limiting plates.

Description

The suspender that is used for cylinder and cylindrical workpieces

Technical field

The utility model relates to mechanical field, and particularly the auxiliary device of workpiece lifting specifically is a kind of suspender that is used for cylinder and cylindrical workpieces.

Background technology

In machinework, use cylinder or cylindrical component through meeting, the cylinder that has or cylindrical component are heavy bigger, can not a dead lift, need to adopt the crane handling usually.In existing, adopt steel rope that the cylindrical part handling is got up more, when lifting by crane unloading, need workman's non-productive operation to accomplish, the work of workpiece handling efficient is low, and is also dangerous.

Summary of the invention

The purpose of the utility model is to provide a kind of suspender that is used for cylinder and cylindrical workpieces, and described this suspender needs artificial auxiliary low, the technical problem of poor safety of efficient that causes when solving cylinder of the prior art or cylindrical component and hanging.

The purpose of the utility model realizes through following technical scheme: it is characterized in that: this suspender comprises at least two suspender branches that laterally arrange; Logical bearing pin is connected between the adjacent suspender branch; Each suspender branch comprises two connecting panels, positioning plate and two suspension hook plates; The upper end of these two connecting panels is hinged through upper pin, and the lower end of two connecting panels is hinged through the upper end of bearing pin and two suspension hook plates in the bearing pin and second in first respectively, and the middle and upper part of two suspension hook plates is hinged on together through lower bearing pin; Be positioned at the suspension hook plate length of the suspension hook plate length of lower bearing pin below greater than the lower bearing pin top; This is provided with positioning plate between bearing pin in bearing pin and second in first, and these positioning plate two ends are provided with the Long Circle hole, in first in the bearing pin and second bearing pin be arranged in this Long Circle hole; These two suspension hook plate bottoms are the circular arc bending; The circular arc bending of two suspension hook plate bottoms is surrounded as the circle hole shape space, and the upper pin of adjacent two suspender branches is an integral body, and the lower bearing pin of adjacent two suspender branches is an integral body.

Upper pin is provided with one and connects otic placode.

The utility model is used for the suspender of cylinder and cylindrical workpieces; Employing lever principle work utilizes the deadweight of connecting panel and suspension hook plate to realize opening of suspender and closes up, and when suspender puts down with weight-lifting equipment, just under the action of gravity of connecting panel, the suspension hook plate is opened; Be convenient to clamping work; When suspender rises with weight-lifting equipment, under the action of gravity of suspension hook plate, close up, cylindrical component between two suspension hook plates is blocked, be convenient to lifting; Positioning plate prevents that the suspension hook plate from intersecting.

The specific embodiment

Through embodiment the utility model is done further explain below in conjunction with accompanying drawing.

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; In the present embodiment, this suspender comprises two suspender branches that laterally arrange, and logical bearing pin is connected between the adjacent suspender branch; Each suspender branch comprises two connecting panels 1, positioning plate 2 and two suspension hook plates 3; The upper end of these two connecting panels 1 is hinged through upper pin 11, and the lower end of two connecting panels 1 is hinged through the upper end of bearing pin 22 and two suspension hook plates 3 in the bearing pin 21 and second in first respectively, and the middle and upper part of two suspension hook plates 3 is hinged on together through lower bearing pin 31; Be positioned at the suspension hook plate length of the suspension hook plate length of lower bearing pin below greater than the lower bearing pin top; This is provided with positioning plate 2 between bearing pin 22 in bearing pin 21 and second in first, and these positioning plate 2 two ends are provided with the Long Circle hole, in first in the bearing pin and second bearing pin be arranged in this Long Circle hole; The opening of suspender below can change when lifting by crane and putting down workpiece; In first in the bearing pin and second bearing pin in the Long Circle hole at positioning plate two ends, slide so that the variation of the rotation of suspension hook plate and its lower ending opening, these two suspension hook plate 3 bottoms are the circular arc bending; The circular arc bending of two suspension hook plate bottoms is surrounded as the circle hole shape space; The upper pin 11 of adjacent two suspender branches is an integral body, and the lower bearing pin 31 of adjacent two suspender branches is an integral body, and two adjacent suspender branches link together through upper pin and lower bearing pin.Upper pin is provided with one and connects otic placode 4, is convenient to be connected with weight-lifting equipment.

During concrete work, hang preceding preparation, select suitable suspender, it is hung in workpiece 5 tops, vertically fall, utilize suspender deadweight suspension hook plate to open automatically, continue to fall, make workpiece be positioned at control position; During lifting, utilize suspension hook plate self gravitation and lever principle with work-holding; When falling part, utilize connecting panel gravity and lever principle, make suspension hook plate opened with certain angle; When the openings of sizes that maintains the suspension hook plate, make opening greater than diameter of work, cooperate weight-lifting equipment, suspender is deviate from, carry out the lifting of next workpiece.

Certainly, this suspender also comprises three or more a plurality of suspender branch that laterally arranges.
