Abstract

The utility model discloses a hanger which comprises a shackle (11) and two parallel four-connecting-rod mechanisms, wherein, each four-connecting-rod mechanism consists of connecting rods (7) and (8), a pressing arm (9) and a hanging arm (10); the pressing arm (9) and the suspension arm (10) form a scissors hanging hook, the top of the two parallel four-connecting-rod mechanisms is penetrated with a connecting shaft (1), and the shackle (11) is sleeved on a part where the connecting shaft (1) is arranged between the two parallel four-connecting-rod mechanisms through shaft holes at two end of the shackle. The hanger can hang disc-type and case-type workpieces of large and middle size, has simple structure, easier operation and wide suitable size range, is safe and reliable, and requires no openings of hung workpieces.

Description

Suspender

Technical field

The utility model relates to and a kind ofly is used for lifting, the suspender of large scale dish class, case class workpiece.

Background technology

In the slim gearless permanent-magnet synchronous traction machine, the rotor cabinet adds man-hour on the horizontal digital-control lathe, because of no axially extending bore on the workpiece can utilize, and workpiece self is heavier, loading and unloading are inconvenience very, and other common hoisting method can not be realized this action again, and a people is difficult to finish this loading and unloading behavior, and very easily injure the operator and smash lathe, time-consuming, effort, dangerous again.The utility model suspender can be guaranteed to lift workpiece by a bit manipulation person, and convenient, reliable.

The utility model content

Technical problem to be solved in the utility model provides a kind of suspender, and in can slinging simply and easily, large scale dish class, case class workpiece, it is wide to be hung workpiece suitable dimensions scope, and simple to operate, safe.

For solving the problems of the technologies described above, the utility model provides a kind of suspender, comprise: shackle 11 and two parallel four-bar linkages, four-bar linkage is made up of connecting

rod

7,8, pressure arm 9 and arm 10, pressure arm 9 and arm 10 constitute the scissors suspension hook, the top of two parallel four-bar linkages is equipped with adapter shaft 1, and the axis hole of shackle 11 by its two ends is nested with at described adapter shaft 1 and is positioned at two parts between parallel four-bar linkage.

During the utility model can be sling easily, large scale dish class, case class workpiece, simple in structure, very easily operation is safe and reliable, and suitable range of sizes is wider, be need not the perforate requirement to hanging workpiece.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail:

Front elevation when Fig. 1 slings workpiece for suspender of the present utility model;

Lateral plan when Fig. 2 slings workpiece for suspender of the present utility model;

Fig. 3 is the enlarged diagram of suspender among Fig. 2.

Reference numeral is among the figure, 1, adapter shaft; 2, back-up ring; 3, spring; 4, adapter shaft; 5, adapter shaft; 6, nut; 7, connecting rod; 8, connecting rod; 9, pressure arm; 10, arm; 11, shackle; 12, hook portion; 13, projecting pressing part.

The specific embodiment

As shown in Figures 2 and 3, suspender of the present utility model comprises: shackle 11 is made up of connecting

rod

7,8, pressure arm 9 and arm 10 with two parallel four-bar linkages, four-bar linkage, and pressure arm 9 and arm 10 constitute the scissors suspension hook.As shown in Figure 1, suspender of the present utility model, the top of the four-bar linkage that two is parallel is equipped with adapter shaft 1, and the axis hole of shackle 11 by its two ends is nested with at described adapter shaft 1 and is positioned at two parts between parallel four-bar linkage.

Among Fig. 2 and Fig. 3, the two ends of connecting rod 7 of the present utility model and connecting rod 8 are provided with pin shaft hole, the upper end and the middle part of arm 10 are provided with pin shaft hole, the lower end has a hook portion 12, the upper end and the middle part of pressure arm 9 are provided with pin shaft hole, the hook portion 12 of lower end and arm 10 lower ends is corresponding to be provided with a projecting pressing part 13, and connecting

rod

7,8, pressure arm 9 and arm 10 are flexibly connected by bearing pin, and the bearing pin two ends have back-up ring 2.

In the pressure arm 9 of two parallel four-bar linkages and the pin shaft hole between the arm 10, can wear another adapter shaft 4 in addition, and between adapter shaft 1 and adapter shaft 4, be provided with a spring 3.Spring 3 is deflated state when suspender is idle, the suspension hook that makes pressure arm 9 and arm 10 form is opening under the elastic force effect.When being hung workpiece and inserted, hung the pressure effect of workpiece on the hook portion 12 of arm 10, make the spring stress after drawing, the opposite side that the projecting pressing part 13 of pressure arm 9 will be hung workpiece automatically compresses.

Also can wear another adapter shaft 5 between the hook portion 12 of two parallel four-bar linkages of the utility model, this adapter shaft 5 is a screw shaft, and it is fixing by nut 6 that its two ends are positioned at described hook portion 12 outsides.When suspender was sling workpiece, as shown in Figure 1, two parallel hook portion 12 all contacted with workpiece, have kept the equilibrium of forces that is subjected to of workpiece, and under the pressure effect of the projecting pressing part 13 of pressure arm 9, can effectively prevent workpiece rocking and swinging in slinging.

The utility model is simple in structure, especially is suitable in the lifting, large scale dish class, case class workpiece, and the safety and the reliability of lifting improve greatly.
