In the embodiment of FIG. 2, the columnar section 110 is formed in a cylindrical shape, but the shape thereof is not limited to that shown in the drawing, but may be provided in the form of a polygonal columnar or the like.

A support 112 having a larger cross-sectional area than the column 110 may be provided on the upper portion of the column 110. The supporting portion 112 disperses the force applied to the hull 10 to prevent the hull 10 from being damaged. In the illustrated embodiment, the support 112 is formed in a disc shape, but may be modified into various shapes not shown. A friction member (not shown) may be provided on the support portion 112 to increase the friction with the hull 10. Or a member (not shown) for reducing the friction with the hull 10 may be provided on the support portion 112 when the support device 100 performs a twisting function when moving the hull.

The leg portion 120 is formed on the lower side of the outer surface of the column portion 110. The leg 120 may include a plurality of legs 122. In the illustrated example, the leg portion 120 is composed of four legs 122, but the number, shape, and installation positions of the legs 122 can be variously modified. The plurality of legs 122 may be formed along the circumference at the lower side of the outer surface of the pillar 110 to support the pillar 110 in a direction perpendicular to the bottom surface 20 of the dock. The legs 122 may be installed on the side surfaces of the pillars 110 so as to be vertically movable.

The lifting and lowering driving unit 130 can raise and lower the leg 120 with respect to the pillar 110. The lifting drive part 130 may be installed in the inner space of the pillar 110. A guide groove 114 may be formed on the outer surface of the column 110 to guide the leg 122 in the vertical direction Z. The leg 122 moves up and down along the guide groove 114 on the side of the pillar 110 during the operation of the lifting drive part 130.

In one embodiment, the lifting driver 130 may be provided as a hydraulic cylinder, but is not limited thereto. For example, the elevation driving unit 130 may elevate the leg portion 120 by another mechanism such as a rack / pinion gear structure, a screw shaft structure, or the like. When the lifting rod 130 is provided as a hydraulic cylinder, one side of the leg 122 passes through the guide groove 114 and is fixed to the rod of the hydraulic cylinder. Accordingly, when the rod is driven by the hydraulic cylinder, the leg 122 is raised and lowered.

The pillars 110 or the legs 120 may be provided with an input unit 140 for operating the lifting and lowering driving unit 130. The input unit 140 may include, for example, one or more buttons provided for the operator to input the elevation driving unit 130 to operate. The operator can operate the elevation driving unit 130 by the input unit 140 to raise or lower the leg 120. [

For example, in a hull drying operation, when a tool necessary for the drying operation, a work carriage, or the like must be moved to the side of the support device 100, or if it is necessary to secure a work or movement space, The leg portion 120 can be raised as shown in FIG.

If it is difficult to secure sufficient working space or moving space by simply raising the leg portion 120 of one support device 100, the input portion 140 of each of the two adjacent support devices 100 is driven, The work space and the moving space can be secured by raising and lowering the leg portion 120 of the apparatus 100. [

The worker inputs a descent command of the elevation driving unit 130 through the input unit 140 when the work truck or the like is moved in a state in which the leg portion 120 is raised or the work is completed between the support apparatuses 100, The portion 120 can be lowered to its original state. FIG. 3 shows an example in which all the legs 122 are lifted and lowered by one lifting and lowering driving unit 130. However, as described later with reference to FIGS. 4 and 5, the respective legs 122 may be lifted individually.

FIG. 4 is a plan view of a support apparatus 100 according to another embodiment of the present invention, and FIG. 5 is a side view for explaining the operation of the support apparatus 100 shown in FIG. In the following description of the embodiments shown in FIGS. 4 and 5, redundant description of the same or corresponding components to those of the previously described embodiments may be omitted.

4 and 5, the support apparatus 100 differs from the previously described embodiment in that it further includes a sensor unit 150 for sensing a surrounding object. The lifting drive unit 130 can raise the leg 120 when the sensor unit 150 senses an object in the vicinity. In an embodiment, the sensor unit 140 may be provided as a laser sensor or a laser distance sensor for sensing an object around it, but the present invention is not limited thereto. Although the sensor unit 150 is installed in the leg 120 in the figure, it may be installed in the column 110 as well. In the embodiment in which the leg portion 120 can be automatically raised and lowered by the sensor portion 150, the input portion 140 may be omitted.

In an embodiment, the sensor unit 150 may include a plurality of sensors installed in a one-to-one correspondence with the plurality of legs 122 to sense surrounding objects. The lifting drive unit 130 can elevate only a leg corresponding to a sensor that senses an ambient object among a plurality of sensors. According to this embodiment, only the leg necessary for movement or work space is raised and lowered, so that the supporting legs of the pillars 110 can be assisted by the remaining legs.

The sensor unit 150 includes a first sensor unit 142 for sensing the peripheral object 30 in the horizontal direction X or Y and a second sensor unit 142 for sensing the peripheral object 30 in the up and down direction Z. [ 2 sensor unit 144 as shown in FIG. When the peripheral object 30 is detected by the first sensor unit 142, the leg corresponding to the sensor unit 142 is raised. The peripheral object 30 is detected by the second sensor unit 142 and the second sensor unit 142 is detected when the peripheral object 30 passes to the lower side of the leg. The surrounding object 30 is not detected. When the second sensor unit 142 senses that the surrounding object 30 is not sensed, the control unit (not shown) controls the elevation driving unit 130 to lower the leg to its original position. 4 and 5, the leg 120 of the support device 100 is automatically operated even when the operator does not input a button when the worker, the work carriage, or the like is moved between the support devices 100. Therefore, The operation time can be shortened.
