Figure 4 shows an exploded perspective view showing a preferred embodiment of the skid rail applied to the present invention, Figure 5, Figure 6 shows an assembled front view and a plan view of FIG.

The skid rail assembly 10 applied to the present invention is formed by a flat base frame 11 and a rail 12 coupled to each other at right angles to form a coupling groove 11a in the flat base frame 11. In the defect groove 11a, the coupling protrusion 12a integrally formed at the lower side of the rail 12 is inserted to weld the base frame 11 to each other.

In the present invention, the two rails 12 of the base frame 11 are coupled to each other so as to be configured in a wedge shape. Of course, the rail 12 may be used in combination with one or two or more depending on the intended use.

The skid rail assembly 10 provided by the present invention is configured to be used in connection with the neighboring skidrail assembly 10.

The connection of the skid rail assembly 10 protrudes one end of the rail 12 coupled to the base frame 11 to the outside of the base frame 11, and extends the opposite end to the outside of the base frame 11. Nest inside each other so that they overlap each other.

And the bottom of the rail 12 of the protruding side to form a coupling engaging projection 12b formed with a clip coupling groove 12c at the bottom, and the coupling projection 12b for incorporation into the base frame 11 on the opposite side To form a coupling groove (11b) to be mutually assembled, the clip coupling groove (12c) is inserted into the coupling groove (11b) exposed to the lower side of the base frame 11) by inserting a detachable clip 13 on both skids Fix the rail assembly 10 integrally.

Then, the side of the connection portion of the neighboring base frame 11 is padded with a reinforcement bracket 14 to weld the connection. The reinforcing bracket 14 is a consumable member that is cut from the base frame 11 when the skid rail assembly 10 is dismantled.

7, 8 and 9 illustrate front, side and top views showing an embodiment of a gripper jack applied to the present invention, and FIG. 10 shows an exploded perspective view of the clamping means applied to the gripper jack of the present invention.

The gripper jack 40 provided in the present invention includes a pressure plate 42 to which the connection rod 30 connected to the tray 20 is coupled, and a pair of transfer cylinders 41 to which the piston rod is coupled to the pressure plate 42. And a pair of clamping means 50 to which the transfer cylinder 41 is fixed, and a roller 43 is installed on the upper surface of the rail 12 and rolls.

The rollers 43 are respectively installed on the rear cover 53, which will be described later, which constitute the pressing plate 42 and the clamping means 50.

The clamping means 50 is integrally assembled by the transfer cylinder 41 and the bolt and nut 54 with the front cover 52 and the rear cover 53 disposed on both sides of the clamp body 51. .

The front and rear covers 52 and 53 have grooves 52a and 53a into which the rails 12 are inserted, respectively, and the clamp body 51 has the clamp members 55 which are in surface contact with the left and right sides of the rail 12. An operating space 51a into which the inside is inserted is formed.

The working space 51a has a tapered inclined pressing surface 51b having a narrower side with a pressing plate 42 when viewed from a flat or bottom surface, and the inclined pressing surface 51b is formed on the clamp member 55. The corresponding inclined surface 55a is formed.

On the contact surface of the clamp member 55 in contact with the rail 12, the non-slip protrusion 55b is formed in various configurations. This makes it possible to increase the clamping efficiency.

That is, when the non-slip protrusion 55b is absent, the clamp member 55 slips without losing the weight of the heavy material 3, thereby losing functionality.

The two clamp members 55 are configured to be supported by a bottom cover 56 assembled to a bottom of the clamp body 51, and the bottom cover 56 has a key groove at an angle equal to that of the inclined pressing surface 51b. 56a is formed, and a key 55c moving along the key groove 56a is assembled in the clamp member 55.

The clamp member 55 is configured to be supported by the restoring means 57 which is an additional component.

The restoring means 57 supports a spring indentation groove 57a formed in parallel with the inclined surface 55a of the clamp member 55, a spring 57b embedded in the spring indentation 57a, and a spring 57b. It is configured to include a spring support (57c) coupled to the rear cover (53).

When the clamping means 50 is unclamped while the spring 57b elastic force of the restoring means 57 is applied to the clamping member 55, the clamping member 55 and the rail 12 are in close proximity and have a slight friction. Free to move in or out of state.

The gripper jack 40 configured as described above is simple in configuration but the clamping means 50 can be perfectly clamped or unclamped according to the operating state of the transfer cylinder 41.

For example, as illustrated in FIGS. 1 and 2, when the heavy material 3 is placed in the tray 20, the weight of the heavy material 3 is driven by driving the transfer cylinder 41 of the gripper jack 40 to move it. By the gripper jack 40 is moved in the reverse direction, the clamping means 50 to clamp the rail 12, the gripper jack 40 by the clamping means 50 is transported in a clamping state The tray 20 is moved as the dragon cylinder 41 continues to operate.

Looking at the clamping process of the clamping means 50 in detail, the clamp body 51 is retracted by the operation of the transfer cylinder 41, in this case the clamp located in the operating space (51a) of the inner side of the clamp body (51) Clamping is performed while the member 55 is in surface contact with the rail 12.

That is, as the clamp body 51 retreats, the inclined guide surface 51b of the clamp body 51 presses the inclined surface 55a of the clamp member 55 as if it is inserting a wedge. Clamp member 55 is coupled to the rail 12 to increase the force to move toward the rail 12 is to strongly clamp the rail (12).

On the contrary, when the conveying cylinder 41 is retracted, the clamp body 51 is moved toward the tray 20 together with the conveying cylinder 41. At this time, the clamping force is released while unclamping is performed. It becomes a state. At this time, while the spring 57b of the restoring means 57 expands, the clamp member 55 is prevented from falling excessively with the rail 12 to smoothly perform the next clamping operation.

Although the technical spirit of the present invention has been described with reference to specific embodiments as described above, the protection scope of the present invention is not necessarily limited to these embodiments, and a simple design change within a range that does not change the technical gist of the present invention. In the case of substitution of common means, the scope of the present invention is clearly clarified.

The heavy weight conveying apparatus provided by the present invention can be used for transporting heavy weight in an industrial site, and can be easily transported to the sea by applying the present invention when the ship is built and moved on land, especially in a shipyard.
