Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a self-

The present invention relates to a heavy object conveying apparatus, in which a plurality of grip members are provided at a lower portion of a main body frame and a conveyance frame to firmly fix a heavy object conveyed along a rail, , A back and forth feeding operation of the feeding cylinder, a repetitive clamping and unclamping operation of the grip member, and a tilting operation of the grip member, whereby heavy materials can be moved on the inclined rails as well as on the parallel rails .

Generally, in the case of drying a large structure manufactured in shipbuilding, marine and construction plant, for example, there is a problem in transportation due to a large shipbuilding ship block structure, so that a separate large dock is produced in the sea, The dock is filled with water to make it float on the sea after the large structure is manufactured. However, there is a problem that it takes a lot of cost to manufacture the dock separately, and it takes a long period of time to dry the ship.

Therefore, recently, in case of drying a large structure, a large dock is not required, and a large structure is dried and transported to the sea for the purpose of launching. In this case, A plurality of rows of rails are installed on an anchored barge, and a plurality of view cars installed up and down the jack-up cylinders are movably installed on the rails, and a plurality of platforms are installed in the shipyard, Blocks are made, and each large structure thus constructed is combined to complete the drying of the ship.

After the large structure has been manufactured as described above, the view car is moved to the lower side of the support groove, and then the jack-up cylinder of the view car is raised, and the large structure is viewed as a jack-up cylinder of the view car.

An apparatus for transporting a large structure thus manufactured along a rail is disclosed in Korean Patent Laid-Open Publication No. 10-2010-0051452.

The heavy material transfer apparatus includes a skid rail assembly 10 provided on the rail support 2 and a wheel 21 moved along the rail 12 of the skidrail assembly 10, A connecting rod 30 connected at one end to the tray 20 and a clamping means 30 connected to the other end of the connecting rod 30 and clamping or unclamping the rail 12 A gripper jack 40 provided with a gripper jack 40 and a hydraulic device 60 for supplying a hydraulic pressure to a transfer cylinder 41 provided in the gripper jack 40,

Such a heavy-goods conveying apparatus can standardize the skid-rail assembly and improve the operability of a gripper jack that is clamped and unclamped on the rail, thereby assuring safe clamping and greatly reducing manufacturing costs.

However, in the conventional heavy material conveying apparatus, the clamping unit 50 is configured to fix only one point of the rail, so that a concentrated load is applied to the skid rail assembly 10 and is broken.

Further, when a failure occurs in the clamping means 50 during transportation of a heavy object, a safety accident may occur because the screedrailer assembly 10 is not fixed, the driving wheel and the clamping means are separately formed, There is a problem in that it is not applicable to a rail having a constant height, and the structure of the clamp means is complicated, resulting in a problem of poor assemblability.

A plurality of grip members 160 of the main frame 100 are operated to operate the transfer cylinder 102 while the main frame 100 is fixed to the rail L. The conveying bar 104 is moved backward according to the operation of the conveying cylinder 102 so that the conveying frame 110 is moved backward along the rail L. [

The grip member 160 of the transfer frame 110 is operated to fix the transfer frame 110 to the rail L at a position where the transfer frame 110 is transferred. The rail fixing of the grip member 160 of the main body frame 100 is released while the transfer frame 110 is fixed to the rail L. [ The main body frame 100 is pushed to the rear side of the conveyance frame 110 which is fixed as the conveyance cylinder 102 is operated in a state where the fixing of the rail L of the main body frame 100 is released, .

By repeating the above-described process, the worker moves forward to a desired position at a desired rear position.

Such a heavy-weight material transferring apparatus not only can transfer heavy workpieces P by a combination of a simple gripping member and a transferring cylinder but also a plurality of gripping portions depending on the operation of the gripping cylinder And at the same time, it has an improved effect that a rigid rail fixing of a heavy-weight conveying apparatus can be achieved as it is fixed to a rail.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.
