[

The gripping clamps H3 are provided to face each other with a through hole 111 therebetween.

The gripping clamp H3 is for grasping the pipe P as described above. For this purpose, the gripping clamp H3 has a circular shape and has a symmetrical surface of the pipe P, for example, And a clamp main body 131 of a fastener.

The clamp main body 131 is moved back and forth by a pair of forward and backward clamping clamps H3 to grip the pipe P or to release the gripping state.

The detection sensor S described in FIG. 1 may be provided around the through-hole 111 of the grip unit main body 110 so as to confirm whether the pipe P reaches a specific position.

As shown in FIGS. 1 and 2, the grip portion main body 110 is lifted and lowered by the lifting and lowering driving portion H1, and the upper and lower lifting and driving portions H1, And a connecting portion 140 having a plate shape.

3, the grip unit main body 110 may be connected to the operation boom B by the up-and-down driving unit H1 and may be connected to the operation boom B by a fixed wire 150 instead of the up- have.

That is, a pair of connection units 140 are provided on the grip unit main body 110 so as to be spaced apart from each other by a predetermined distance, and a fixing wire 150 is installed on the pair of connection units 140 to operate the grip unit main body 140 Can be installed on the boom.

For this, a through hole 141 may be formed at both ends of the connection portion 140, and then the connection member 150 may be inserted into the through hole 141 and fixed to the operation boom.

As shown in FIG. 3, the connecting member 150 may be formed of a wire, and a fixing member 160 may be provided at an end of the wire so that the fixing member 160 may be installed on the operation boom by bolts or the like.

The fixing member 160 is formed with a through-hole through which the end of the outer ear is connected and a bolt or the like is fastened.

1, the lifting / lowering drive unit H1 is installed on the connecting member 150 between the operation boom B and the gripping unit main body 110 to elevate and lower the gripping unit main body 110 to adjust its height The up-and-down driving unit H1 may be a well-known hydraulic cylinder or a pneumatic cylinder.

At this time, the pump for supplying the working fluid to the up-and-down driving unit H1 may be installed in the grasping portion main body 110 or may be provided outside and supply the working fluid by the piping.

 1 and the forward / backward driving portion H3 shown in FIG. 2 can also use a well-known hydraulic cylinder or a pneumatic cylinder.

1, the adjustment driving unit H4 may be provided between the operation boom B and the elevating and lowering driving unit H1 to adjust the angle of the elevating and lowering driving unit H1 in the left and right direction in the drawing. The adjustment drive H4 may also be a hydraulic cylinder or a pneumatic cylinder.

As shown in FIGS. 4 and 5, the lifting portion 200 is a hollow box-like shape having a top surface opened and a bottom at a bottom portion of the lifting body 210 on which the rotation plate 220 is installed. Respectively.

The rotating plate 220 is installed on the bottom of the lifting unit 210 and a wire W extending through the pipe P is branched at mutual contact portions of the rotating plates 220, And the opposite side of the contact portion of the rotating plate 220 is rotatably installed to the lifting body 210 by a pin or the like.

4, the rotary plate 220 is installed on the left and right sides of the bottom of the lifting body 210, and a portion of the rotary plate 220, which is in contact with the lifting body 210, The opposite side is made rotatable.

When the wire W rises, the branched wire W is installed at a rotating part of the rotating plate 220. Since the rotating plate 220 can not rotate in the upward direction due to the lifted object, The body 210 is lifted, and accordingly, the support 230 is lifted.

Of course, the upper surface of the rotary plate 220 may be hooked by an engagement protrusion (not shown) formed at one side of the lifting unit body 210 to prevent the rotary plate 220 from rotating in the upward direction.

Wires W branched to the rotary plate 220 are respectively installed and the wires W can be installed in the forward and backward directions of the rotary plates 220 as shown in FIG.

A support pipe 230 is installed on the upper portion of the lifting main body 210 so that the pipe P is installed on the support pipe 230. Further, the support member 230 is rotatably installed on the lifting unit body 210, and may have a widely known pin coupling method.

The support portion 230 is rotatably connected to the upper end of the opposed portion of the lifting body 210 at both ends in a " C "shape.

A weight (240) is provided in the support (230). This weight 240 acts to bias the center of gravity of the weight 240 away from the rotation axis when the support 230 is erected so that the support 230 rotates in the direction in which the weight 240 is installed This is explained separately.

Hereinafter, a lifting method using the lifting apparatus of the present invention will be described with reference to FIGS. 1 to 5. FIG.

The lifting unit 200 is lifted by pulling the wire W by the winch unit WI. This is because the wire W is connected to the rotary plate 220 of the lifting unit 200 and the rotary plate 220 is not pivotable upward so that the lifting unit 200 is lifted when the wire W is pulled.

When the lifting section 200 is lifted, the support pipe 230 is lifted so that the pipe P installed on the support pipe 230 is also lifted so that the pipe P is inserted into the through hole 111 of the grip 100 do.

When the pipe P is inserted into the through hole 111, the pipe P is fixed by the gripping arm 120 or the gripping clamp H3 of the gripping part 100. When the pipe P is inserted into the through hole 111, Whether or not the pipe P is inserted into the pipe 111 can be determined by sensing the position of the pipe P by the detection sensor S. [

At this time, the operating boom B is driven to move the lifting portion 200 to the loading position. That is, the length of the operation boom B is elongated or the operation boom B is rotated to move the position of the lifting part 200. Thereafter, when the winch portion WI loosens the wire W, the rotary plate 220 of the lifting portion 200 is rotated downward around a portion of the lifting portion 220 to discharge the lifted material.

On the other hand, it is possible to lower the wire W by a predetermined length when it touches the ground (or ship) to load the lifting body on the lifting portion 200.

The pipe P is connected at one end to the center of the support 230 and the support 230 extends from the pipe P to both sides and extends in the extending direction of the pipe P at both ends .

An end portion extending in the extending direction of the pipe P is rotatably connected to the lifting body 210.

The lifting unit main body 210 is an upwardly open hexahedron housing, and both ends of the supporting unit 230 are rotatably connected to the center portions of the sides of the lifting unit 210 facing each other.

When the winch unit WI further loosens the wire W after the lifting unit 200 is lowered to a state where the lifting unit 200 is placed on the ground or the like, the weight 230 provided on the support unit 230, Is rotated to the one side together with the pipe P so that the support 230 is tilted to one side in the opened part of the upper part of the lifting body 210,

As a result, the upper surface of the lifting body 210 is opened more widely, so that it is easier to insert the lifting body into the lifting body 210.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
