Abstract
The invention discloses an end socket lifting tool which can lift a large end socket easily. The end socket lifting tool comprises a lifting bracket; at least two bayonets which can contain the thickness of an end socket are formed in the lifting bracket; the parts, positioned on one sides of the bayonets, of the lifting bracket are respectively hinged with a clamping rod; one ends of the clamping rods respectively extend into the bayonets; the other ends of the clamping rods are respectively positioned outside the lifting bracket. The end socket lifting tool has the advantages that the end socket can be clamped very well by utilizing the combination of the clamping rods and the bayonets when the end socket is lifted.
Description
Technical field
The present invention relates to a kind of end socket hoisting tool.
Background technology
Conventional lifting end socket frock is two hooks, when lifting, utilizes hook to snap into the edge of end socket, then utilize the steel rope hook of slinging, due in when lifting, hook can tilt, thereby thereby utilizes the inclination of hook that two ends of hook and end socket edge are close to end socket is clamped.This frock is lifted by crane small-sized end socket gripping power and can be manageed it, but because large-sized end enclosure weight is large, wall thickness is large, and the gripping power of hook is just not much of that like this, and end socket easily drops, and this is very dangerous to production scene.
Summary of the invention
Technical matters to be solved by this invention is: a kind of end socket hoisting tool that can lift by crane large-sized end enclosure is easily provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of end socket hoisting tool, comprise hoisting bracket, on hoisting bracket, be provided with at least two bayonet sockets that can hold end socket heavy wall, the side that hoisting bracket is positioned at bayonet socket is hinged with respectively kelly, one end of kelly is stretched into respectively in bayonet socket, and the other end lays respectively at the outside of hoisting bracket.
Described hoisting bracket is inverted U-shaped beam, and the quantity of bayonet socket is two, and lays respectively at the two ends of U-shaped beam.
Described hoisting bracket is panel, and the quantity of bayonet socket is two, and the distance between two bayonet sockets is suitable with end socket diameter.
The vertical section of described hoisting bracket is inverted U-shaped, and the quantity of bayonet socket is three, and is distributed on respectively on the lower edge of hoisting bracket.
That end end that described kelly is arranged in bayonet socket is provided with the edge that is involute shape, and the expansion direction of involute and bayonet socket towards the opposite is covered with on edge and has sawtooth.
The invention has the beneficial effects as follows: when lifting end socket, utilize the combination of kelly and bayonet socket, can fine clamping end socket.

In figure, 1, U-shaped beam, 2, end socket, 3, bayonet socket, 4, kelly, 5, sawtooth, 6, panel.
The specific embodiment
Describe specific embodiment of the invention scheme below in detail.
End socket hoisting tool of the present invention, comprise hoisting bracket, be provided with at least two bayonet sockets that can hold end socket heavy wall on hoisting bracket, the side that hoisting bracket is positioned at bayonet socket is hinged with respectively kelly, one end of kelly is stretched into respectively in bayonet socket, and the other end lays respectively at the outside of hoisting bracket.
It is specially: the first embodiment, as shown in Figure 1, end socket hoisting tool of the present invention comprises U-shaped beam 1, the two ends of U-shaped beam 1 are respectively arranged with the bayonet socket 3 that can hold end socket 2 heavy walls, the two ends of U-shaped beam 1 are hinged with respectively kelly 4, one end of kelly 4 is stretched into respectively in bayonet socket 3, and the other end lays respectively at the outside of U-shaped beam 1.In order further to improve gripping power, that end end that described kelly 4 is arranged in bayonet socket 3 is provided with the edge that is involute shape, and the expansion direction of involute and bayonet socket 3 towards the opposite is covered with on edge and has sawtooth 5.
As shown in Figure 2, the second embodiment, end socket hoisting tool of the present invention comprises panel 6, the two ends of panel 6 are respectively arranged with the bayonet socket 3 that can hold end socket 2 heavy walls, and the distance between two bayonet sockets 3 is suitable with end socket diameter.The two ends of panel 6 are hinged with respectively kelly 4, and one end of kelly 4 is stretched into respectively in bayonet socket 3, and the other end lays respectively at the outside of panel 6.In order further to improve gripping power, that end end that described kelly 4 is arranged in bayonet socket 3 is provided with the edge that is involute shape, and the expansion direction of involute and bayonet socket 3 towards the opposite is covered with on edge and has sawtooth 5.After adopting panel 6, in the process of lifting, due to the position of panel 6 between two bayonet sockets 3 linearly and intensity enough large, therefore can not cause the end socket of wall thickness little (can produce deformation while utilizing common hoisting tool lifting under the effect of gripping power and end socket deadweight) to produce distortion.
The structure of the third embodiment and the difference of the first embodiment and the second embodiment are that the shape of hoisting bracket is different, the shape that is specially hoisting bracket is the same with end socket, it is inverted U-shaped to be that vertical section is, the quantity of bayonet socket is for being set to three, and is distributed on respectively on the lower edge of hoisting bracket.At this, just repeated no more.
Working process of the present invention is: as shown in Figure 1, the edge of end socket 2 is snapped in bayonet socket 1, then with steel rope, tie up that end that is positioned at U-shaped beam 1 outside at kelly 4, because steel rope makes progress to the application force of kelly 4, therefore that end that kelly 4 is arranged in bayonet socket 3 is with regard to downwards, sawtooth 5 is just attached on the outer wall of end socket 2 like this, the inwall of end socket 2 is attached on the inwall of bayonet socket 3, end socket 2 is heavier, the gripping power of 5 pairs of end sockets 2 of sawtooth is just larger, therefore can firmly end socket 2 be clamped, can not produce the situation that end socket 2 drops
Improved the safety while producing.The working process of the second embodiment and the third embodiment is the same with the first, at this, has not just repeated.
