Abstract

The utility model relates to the technical field of cranes and in particular relates to a forceps clip used on a crane and used for lifting barrel-shaped objects. The forceps clip comprises a hook fixing ring, two symmetrical booms rotatably connected with the hook fixing ring, and a spring arranged between the two symmetrical booms, wherein the spring is connected with the two symmetrical booms through metal hanging rings arranged at the centers of the two symmetrical booms, end arms of the two symmetrical booms are respectively provided with a U-shaped hook wrench, and the inner side of the U-shaped hook wrench at one end is provided with a friction plate which is provided with a friction surface with textures. The forceps clip has the beneficial effects of being simple in structure, portable, convenient to operate, and easy to lift in a relatively narrow space. In the lifting process, the forceps clip is stable and fast, good in safety performance and especially applicable to the lifting of the barrel-shaped objects such as oil barrels and medicine barrels on a production site.

Description

The clamp that is used for the barrel-shaped object of crane handling

Technical field

The utility model relates to the crane technical field, particularly a kind of clamp for the barrel-shaped object of crane handling.

Background technology

Crane in bridge type claims again crane or overhead traveling crane, be a kind of crossbearer in the workshop, warehouse and overhead, the stock ground weight-lifting equipment that carries out the material handling.The track overhead by both sides vertically moves, and can take full advantage of the space handling material below crane span structure, is not subjected to the obstruction of wayside equipment, uses particularly extensive at workshop at present.

When using crane handling drum-shaped object, at first need crane to hang the clamp that head tangles the drum-shaped object, then pass through the clamp of drum-shaped object, pin outstanding bucket edge, drum edge, be transported at last the appointed place.

The lifting principle: usually according to the shape of drum edge, the tongs mouth is tied up to herein, along with the tongs pull-up, drum auto lock so firmly fastens the edge of drum, drum can be transported.

Due to for the production of drum of a great variety, most of drum the bucket edge design satisfy the handling of tongs auto lock.But it is more shallow to still have minority to work as the corner angle at drum edge, and perhaps due to the frayed impact of drum, edge is polished smooth, causes the suspension hook can't fastening, causes tongs to be difficult for lifting delivery.In case carry out lifting under unfavorable condition, easily like this in the handling process, case accident occurs, and the danger of pounding thing, hurting sb.'s feelings is arranged.

Present solution is:

(1) drum that usually adopts steel rope will need to lift firmly ties up, and the head that hangs by the crane lower end after being tied in a knot triggers the implementation handling, but this method is in binding, the inconvenience of charge and discharge operations process;

(2) by making simple and easy iron bar, and the fence surrounding iron hoop of burn-oning, facilitate steel wire penetrating.The drum of needs lifting is put into iron bar, be tied after steel wire penetrating four side iron hoops, then by hanging head delivery.But this method not only increases the weight of handling, and the iron bar floor area is larger, is difficult for the space narrow in the operating area and uses.

Summary of the invention

It is a kind of simple in structure, light, easy to operate that the purpose of this utility model is to provide, and is easy to the comparatively narrow lifting in space, steady in hoisting process, quick, the clamp that is used for the barrel-shaped object of crane handling that safety performance is good.

The purpose of this utility model realizes by following technical proposals:

Clamp for the barrel-shaped object of crane handling of the present utility model, it is characterized in that comprising the hook set collar, link up with therewith the jib of two symmetries that set collar is rotationally connected, be arranged on the spring between the jib of these two symmetries, metal link on the midway location of the jib of described spring by being arranged on described two symmetries is connected with the jib of described two symmetries, be respectively equipped with U-shaped hook hand on the jib end arm of described two symmetries, and U-shaped hook hand inboard at one end is provided with friction plate, is with veined friction face on this friction plate.

The beneficial effects of the utility model are, it is simple in structure, light, easy to operate for the clamp for the barrel-shaped object of crane handling of the present utility model, is easy to the comparatively narrow lifting in space.Steadily, fast, safety performance is good, is specially adapted to the handling of the barrel-shaped objects such as production scene oil drum, explosive barrel in hoisting process.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A section enlarged drawing of Fig. 1.

Fig. 3 is that the utility model uses constitution diagram.

The specific embodiment

Given embodiment further illustrates the specific embodiment of the present utility model below in conjunction with accompanying drawing.

as Fig. 1, shown in Figure 2, clamp for the barrel-shaped object of crane handling of the present utility model, it is characterized in that comprising hook set collar 1, link up with therewith the jib 2 of two symmetries that set collar 1 is rotationally connected, be arranged on the spring 3 between the jib 2 of these two symmetries, metal link 4 on the midway location of the jib 2 of described spring 3 by being arranged on described two symmetries is connected with the jib 2 of described two symmetries, be respectively equipped with U-shaped hook hand 5 on the jib 2 end arms of described two symmetries, and U-shaped hook hand at one end 5 is provided with friction plate 5-1 with the object contact side, be with veined friction face 5-2 on this friction plate 5-1.

as shown in Figure 3, principle of work of the present utility model: at first drum 6 is placed in level attitude, two U-shaped hook hands 5 of clamp are hooked in drum 6 two end cap, because the friction face 5-2 of the texture on U-shaped hook hand 5 has increased friction force when contacting with bung, the hook hand of clamp can be near living bung, when promoting crown block hook, under the effect of spring tension, clamp is subject to pulling force upwards, the U-shaped hook hand 5 of clamp automatically and the tight interlock of bung, difficult drop-off in operational process, , safety performance is good, be specially adapted to the production scene oil drum, the handling of the barrel-shaped object such as explosive barrel.

Claims

1. clamp that is used for the barrel-shaped object of crane handling, it is characterized in that comprising the hook set collar, link up with therewith the jib of two symmetries that set collar is rotationally connected, be arranged on the spring between the jib of these two symmetries, metal link on the midway location of the jib of described spring by being arranged on described two symmetries is connected with the jib of described two symmetries, be respectively equipped with U-shaped hook hand on the jib end arm of described two symmetries, and U-shaped hook hand inboard at one end is provided with friction plate, is with veined friction face on this friction plate.
