Abstract

Disclosed is a lifting hook used for loading and unloading a wire coil, relating to a loading and unloading lifting hook used in wire production. A flying ring(1)is arranged at the upper end of a hanger rod(10); the middle part of the hanger rod(10)is sleeved in a movable sleeve(3); a stopper ring(2) is arranged at the upper end of the movable sleeve(3); two sides of the lower part of the movable sleeve(3) are respectively movably connected with two upper movable arms(7) through upper arm fixing bolts(4); the middle parts of the upper movable arms(7) are movably connected with the lower ends of lower movable arms(6), the upper ends of which are movably connected with the lower end of the hanger rod(10) through lower arm fixing bolts(5); and the lower ends of the upper movable arms are respectively provided with crane clamping clasps(8). The lifting hook used for loading and unloading a wire coil is simple in structure, is particularly suitable for hoisting wire coils and is relatively low in cost.

Description

A kind of dish tool loading and unloading cargo hook gear

[technical field]

The utility model relates to a kind of lead production with the loading and unloading suspension hook, relates in particular to a kind of dish tool loading and unloading cargo hook gear.

[background technology]

Pipe twisting machine is installed the drum telpher, it can reduce the labour intensity of operative employee when twisted wire is produced to greatest extent, be by the overhead traveling crane hoisting device drum to be installed in the pipe twisting machine, it is to be sling and installed by overhead traveling crane and suitable V-belt that original-pack pipe twisting machine drum is installed; So the V-belt must be wrapped on the drum, extracts the V-belt out behind the pipe twisting machine of packing into; But in extraction, the V-belt is easy to collude and is suspended on the pipe twisting machine in-to-in parts, installs the used time of drum thereby increase, and has influenced the progress of producing; Because the V-belt is stressed very big in hoisting process, so must regularly replace, this has also increased productive costs accordingly.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model discloses a kind of dish tool loading and unloading cargo hook gear, described dish tool loading and unloading cargo hook gear is simple in structure, especially is fit to the lifting of drum, and cost is also relatively low.

In order to realize described goal of the invention, the scheme that the utility model adopted is:

A kind of dish tool loading and unloading cargo hook gear, upper end at suspension rod is provided with suspension ring, described suspension rod middle part is sleeved in the moving casing, described moving casing upper end is provided with position-arresting ring, both sides, moving casing bottom respectively by the upper arm bolt of rear end plate with two on movable arm flexible connection, described lower end of going up movable arm middle part and following movable arm flexibly connects, in the upper end of movable arm down by of the lower end flexible connection of underarm bolt of rear end plate with suspension rod, described two upward the movable arm lower end be respectively equipped with the crane grab.

Owing to adopted technique scheme, the utlity model has following preceence;

Described dish tool loading and unloading cargo hook gear is welded by reinforcing bar, steel plate, bolt, and angle steel assembling.Only need block the both sides grab respectively the edge of drum in when lifting,, thereby make the both sides grab produce inside clamping power because under the combined action of the action of gravity of drum and bolt, moving casing moves up, thus the tightness when having guaranteed to sling drum; After hanging the appropriate location, allow suspension hook descend, moving casing moves down, and the both sides grab produces the tension force to both sides, thereby makes grab naturally separately.

[description of drawings]

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

Among the figure: 1, suspension ring; 2, position-arresting ring; 3, moving casing; 4, upper arm bolt of rear end plate; 5, underarm bolt of rear end plate; 6, following movable arm; 7, go up movable arm; 8, crane grab; 9, drum; 10, suspension rod.

[specific embodiment]

Now in conjunction with the accompanying drawings the utility model is described in detail:

At the loading and unloading of the dish tool described in Fig. 1 cargo hook gear, in the upper end of suspension rod 10 suspension ring 1 are set, described suspension rod 10 middle parts are sleeved in the moving casing 3, described moving casing 3 upper ends are provided with position-arresting ring 2, both sides, moving casing 3 bottom respectively by upper arm bolt of rear end plate 4 with two on movable arm 7 flexible connections, described lower end of going up movable arm 7 middle parts and following movable arm 6 flexibly connects, flexibly connect by the lower end of underarm bolt of rear end plate 5 in the following upper end of movable arm 6, go up movable arm 7 lower ends and be respectively equipped with crane grab 8 for described two with suspension rod 10.

Implement the using method of dish tool loading and unloading cargo hook gear described in the utility model, before using suspension hook 1 is hung on the overhead traveling crane suspension hook, when lifting, only need both sides grab 8 is blocked respectively the edge of drum 9, because the action of gravity of drum 9 makes under the combined action of upper arm bolt of rear end plate 4,5 turning joints of underarm bolt of rear end plate, being arranged on suspension rod 10 exterior moving casings 3 moves up, thereby make both sides grab 8 produce inside clamping power, thereby the tightness when having guaranteed to sling drum 9.After hanging the appropriate location, allow suspension hook descend, moving casing 3 moves down, the tension force that both sides grab 8 produces to both sides, thus make crane grab 8 naturally separately, drum breaks away from cargo hook gear.

Claims

1, a kind of dish tool loading and unloading cargo hook gear, it is characterized in that: suspension ring (1) are set in the upper end of suspension rod (10), described suspension rod (10) middle part is sleeved in the moving casing (3), described moving casing (3) upper end is provided with position-arresting ring (2), go up movable arm (7) flexible connection by upper arm bolt of rear end plate (4) with two respectively in moving casing (3) both sides, bottom, described lower end of going up movable arm (7) middle part and following movable arm (6) flexibly connects, flexibly connect by the lower end of underarm bolt of rear end plate (5) in the following upper end of movable arm (6), go up movable arm (7) lower end and be respectively equipped with crane grab (8) for described two with suspension rod (10).
