Abstract

The present invention is a dedicated device for dismantling an outer material box received from a shipyard. In the prior art, it is dismantled using a forklift or a tool, so that it takes a lot of human resources and time, and there is a risk of equipment damage and safety accident. In view of the above, the present invention provides a circular saw which is capable of dismounting an outer material box by lifting up the upper part of the box by using a circular saw to cut four lower surfaces of the box while rotating the box mounted on the rotary turntable, And to provide a box disassembling apparatus using the same.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stationary box disassembling apparatus using a circular saw,

The present invention relates to a box disassembly apparatus for disassembling a wooden box of equipment materials, and more particularly, to a disassembling apparatus for disassembling a wooden box of equipment materials, more specifically, To a disassembled stationary box using a circular saw.

In shipyards, shipbuilding and offshore construction materials are of various sizes and are packed in boxes using wood. When such a box of material is received, the box is disassembled at each site and the equipment is installed on the ship or site. Currently, there is no dedicated device to dismantle the wooden box that packs the equipment, so it is dismantled using a forklift and a manual jig.

Outside material boxes to be loaded in the shipyard are 2 ~ 4M in case of medium to small size, and one box of forklift is used to dismantle the box by removing the front panel, side, and back after removing the top panel. . In the case of a large box, the height is more than 4m, and three forklifts are used. After removing the front plate, the side plate is removed while supporting the upper plate, and the upper plate and the rear plate are disassembled by pushing them. There are eight workers working for forklift driver, signaling, and water worker. In the case of a bolting type box, the operator dismantles the bolt at the bottom, dismantles the box using a crane, and one crane and five workers work.

However, in the dismantling operation of the outer box using the forklift, the crane and the manual jig without the device for disassembling the box as described above, it is difficult to enter the fork of the forklift when the upper plate is disassembled and the disassembly is performed using the lower end of the forklift fork There is a risk of damage to the equipment inside the box caused by forklift fork.

Also, in the case of a large box, it is necessary to remove the side plate while supporting the upper plate, and the upper plate and the rear plate must be disassembled in a manner of pushing and pushing.

In this way, we are currently working on forklift fork or manual work due to lack of special equipment to dismantle the wooden box of the equipment in the domestic shipyard. We are also aware of the risk of material damage, safety accidents, musculoskeletal accidents, There is also a problem that complaints occur, human resources and time are consumed.

The present invention provides a dedicated device for disassembling an outer material box received from a shipbuilder as described above, and is characterized in that a box mounted on a rotary turntable is rotated while a lower surface of the box is cut using a circular saw, and a rotary hoist is used So as to remove the upper portion of the box, and to provide a box disassembling apparatus using the circular saw.

The present invention minimizes equipment and human resources such as forklifts needed for dismantling small and medium sized boxes, and shortens time and improves productivity by removing the upper end portion by lifting up the hoist by cutting the lower end portion with a circular saw. .

In the box disassembling apparatus using the circular saw according to the present invention,

A turntable installed on the base frame for rotating the box and turning the cut surface;

A cutting top module for cutting the lower end of the box placed on the turntable;

And a lifting device for lifting an upper portion of the box after cutting the lower surface of the lower surface of the box and transporting the upper portion of the box.

The base frame is further provided with a stopper for preventing the box that is put on the turntable from coming off and limiting the cutting plane reference line.

And a fixing device for supporting and fixing the box mounted on the turntable so as to prevent the shake and deviation of the box mounted on the turntable.

The fixing device is provided with a pair of opposite sides of the box,

A fixed frame fixedly installed on the base frame;

A ball screw rotatably installed on the fixed frame;

An ascending / descending device for rotating the ball screw;

A forward / backward device installed at an upper end of the ball screw and being raised / lowered by rotation of the ball screw, the operation end being moved forward and backward to fix and release the box;

And a fixed support plate fixed to the operation end of the forward / backward device and fixedly supported on the side surface of the box when the box is fixed.

The cutting top module comprises:

A circular cutting saw rotated by a motor;

A cutting top feed device for linearly reciprocating the cutting top;

A cutting saw depth adjusting device for adjusting the depth of the cutting saw with respect to the cut surface of the box by regulating the forward and backward movement of the cutting saw,

And a cutting saw height adjusting device (34) for adjusting the height of the cutting saw (31).

The above-

A vertical frame fixedly installed vertically on the outer side of the base frame;

A horizontal frame horizontally fixed to an upper end of the vertical frame;

A swing device for swinging the horizontal frame by separating and coupling the middle part of the vertical frame;

A head unit fixedly installed on a front end of the horizontal frame;

And a lifting hook fixed to the end portion of the fixed wire connected to the lifting means and having both hooks fixed to the lower portion by a wire so as to lift up the upper portion of the cut box.

Further, the present invention provides a control panel for controlling operations of the turntable, the cutting-saw module, the fixing device, and the head device; And a remote controller for inputting a remote control command to the control panel.

Since there is a possibility of damage and disconnection of the dismantling equipment by the conventional forklift, it is possible to prevent the accident, the material damage and the musculoskeletal diseases by providing the dismantling device for the automatic dismantling of the foil automatically without depending on the skill of the forklift and the operator There is an effect that can be. Also, it is possible to work through a lot of conventional workers and a skilled worker of a forklift by knowing a simple task.
