On the other hand, in the present invention, the connecting and separating means of two embodiments in order to mutually connect or separate the fixing clamp 400 disposed on the rear of the four posts and the pressing clamp 500 disposed on the front of the square posts 100 . (600) is provided.

First, the connecting and separating means 600 of the first embodiment connects the fixing clamp 400 and the crimping clamp 500 with an installation guide rod 617 as shown in the accompanying drawings 6 to 9, A flat boss 611 is formed inside the front edge of the first fixing plate 410 , and a bar through hole 612 is formed at a position of the first compression plate 420 corresponding to the flat boss 611 .

In addition, a first installation hole 613 is formed therethrough at a position of the second fixing plate 510 corresponding to the rod through hole 612 , and a second compression plate 520 corresponding to the first installation hole 613 . A second installation hole 614 is penetrated at the position.

In addition, one end of the installation guide rod 617 is fixed with the flat boss 611 and bolts while penetrating the rod through hole 612 .

When the other end of the installation guide rod 617 fixed in this way is fixed through the first and second installation holes 423 and 524 constituting the compression clamp 500, the fixing clamp 400 and the pressing clamp 500 are In a state of being interconnected, the first crimping plate 420 and the second crimping plate 520 move to the blind post 100 and are fixed in close contact with each other.

That is, the installation guide rod 617 is connected to the fixing clamp 400 by entering the pressing clamp 500 in the horizontal direction in a fixed state.

Here, in order to easily and conveniently fix the second fixing plate 510 and the second fixing plate 510 that enter the other end of the installation guide rod 617, the stopper 618 at the other end of the installation guide rod 617 has a relatively large outer diameter. is formed with

In addition, the first and second installation holes 423 and 524 are stopper through holes 615 so that the first stopper 618 passes through the first and second installation holes 423 and 524 so that the installation guide rod 617 can be caught after the stopper 618 passes. The rod engaging hole 616 is formed with this relatively large inner diameter and communicates with the upper portion of the stopper through hole 615 but has a relatively small inner diameter, that is, an inner diameter of a size into which the installation guide rod 617 can be inserted. do.

Accordingly, the stopper 618 passes through the stopper through-holes 615 formed in the second fixing plate 510 and the second compression plate 520, respectively, and is disposed on the outer surface of the second fixing plate 510. ) when the whole is lowered, the installation guide rod 617 is accommodated in the rod locking hole 616 and is hung.

Thereafter, by rotating the second screw shaft 530, after the second pressing plate 520 is in close contact with the blind post 100, the second fixing plate 510 is pushed and moved in the spotter direction and can be fixed in close contact, By doing so, it is possible to quickly and conveniently fix the compression clamp 500 to the fixing clamp 400 without a separate fixing tool.

Next, the connecting and separating means 600 of the second embodiment has an inside of the letter "T" shape at the front end of the plate body that protrudes forward from both sides of the first fixing plate 410, as shown in the accompanying drawings 10 to 13. Doedoe, the front open connection fixing groove 621 is formed.

In addition, the connection fixing jaw 622 is inserted and fixed from above the connection fixing groove 621 to the rear end of the plate body that protrudes backward from both sides of the second fixing plate 510 corresponding to the connection fixing groove 621. is formed

Here, after the connection fixing jaw 622 is inserted into the connection fixing groove 621, the upper part of the connection fixing groove 621 is opened and the lower part is closed, so that the inserted connection fixing jaw 622 is connected. It is configured to be fixed by being caught in the lower part of the fixing groove 621 .

Accordingly, the compression clamp 500 is configured to be inserted and fixed in the vertical direction with the fixing clamp 400, so that the first embodiment connected in the horizontal direction and the coupling direction method are different to match the environment and conditions at the work site. It is possible to choose a suitable method to use.

Here, the first and second compression plates 420 and 520 moving with the rotation of the first and second screw shafts 430 and 530 must be moved forward and backward without being rotated in order to be in close contact with the blind post 100 . .

In order to solve this problem, the first and second compression plates 420 and 520 connected to the first and second screw shafts 430 and 530 are configured to be connected to each other by an idle rotation means 700 .

The idling means 700 is formed with a first locking plate 710 having a relatively large outer diameter at the other ends of the first and second screw shafts 430 and 530, and is fixed with the first locking plate 710 with bolts. A second locking plate 720 is configured, and an idle space 730 spaced apart by a step is provided between the first and second locking plates 710 and 720 .

In addition, in the middle of the inner middle of the first and second rotation holes 423 and 524 formed in the first and second compression plates, the central portion is formed with a relatively small inner diameter so as to be inserted into the idle space 730 . this is formed

That is, the receiving locking projection 740 is formed to have a ring shape protruding inward from the first and second rotation holes 423 and 524 .

Accordingly, when the first locking plate 710 is inserted into one side of the first and second rotation holes 423 and 524 and the second locking plate 720 is inserted into the other side, as a result, the receiving locking jaw 740 ) The first and second locking plates 710 and 720 are arranged on both sides and hung, and when the first and second screw shafts 430 and 530 rotate, the first and second locking plates idly rotate while the first and second compression plates 420 ) 520 is not rotated and can be moved forward or backward.

On the other hand, it is inconvenient to install the compression clamp 500 in a state where the operator supports the fixing clamp 400, which is first disposed on the blind post 100, thereby causing a safety accident due to the fall of the fixing clamp 400 can do.

In order to solve this, the temporary fixing means 800 is configured to temporarily fix the fixing clamp 400 to the blind post 100 .

The temporary fixing means 800 forms a third spiral boss 810 in which a spiral is formed in the inner diameter on the lower side of the fixing clamp 400 as shown in the accompanying drawings 3 and 8, and the third spiral boss ( A third screw shaft 820 with external threads formed on the outer periphery to be fastened with the 810 is configured.

Here, the third spiral boss 810 is formed on the lower side because the first fixing plate 410 constituting the fixing clamp 400 is fixed, and a moving plate 840 to which a stationary magnet 880, which will be described later, is fixed. It is preferable to move forward and backward using the third screw shaft 820 .

In addition, a third rotation handle 830 is fixed to one end of the third screw shaft 820 in a state exposed to the outside of the first fixing plate 410 , and the other end of the third screw shaft 820 is as described above. The same idling means 700 is connected to the third rotation hole 850 to be installed with the moving plate 840 .

That is, the first locking plate 710 is installed on the third screw shaft 820 and fixed with the second locking plate 720 in a state inserted into one side of the third rotation hole 850, but an idle space ( 730) is formed, and the receiving locking projection 740 protruding inwardly is accommodated in the third rotation hole 850, so that the moving plate 840 is not rotated and only forward and backward is possible.

In addition, third guide pins 870 protrude from both sides of the front surface of the moving plate 840 , and are installed through the third pin holes 860 formed in the first fixing plate 410 .

In addition, the fixed magnet 880 is fixed to the front surface of the moving plate 840, and is configured to be fixed by magnetic force with the blind post 100 made of a metal material.

Accordingly, when the third screw shaft 820 starts to rotate by rotating the third rotation handle 830 forward, the moving plate 840 advances and the fixed magnet 880 is attached to and fixed with the blind pole 100 by magnetic force. Thus, the operator can connect the pressing clamp 500 using the connecting and separating means 600 without supporting the fixing clamp 400 .

In the case of dismantling in reverse, if the third rotation handle 830 is rotated in reverse, the third screw shaft 820 is moved backward, and the fixed magnet 880 is separated from the blind support 100 and can be separated.

Furthermore, when a heavy object is lifted by the crane 300 , the crane column 310 may be bent forward to generate a load and be damaged or cause a safety accident.

In order to solve this, as shown in the accompanying drawings Figs. 2 and 8, the close contact support plate 900 in which the column through hole 910 through which the crane column 310 vertically penetrates is disposed, and the close contact support plate 900 Support pins 920 each protruding from both sides of the lower surface are formed.

In addition, support pin fixing grooves 930 are formed on both sides of the rear surface of the fixing clamp 400 corresponding to the support pin 920 , that is, the rear surface of the first fixing plate 410 so that the support pin 920 is inserted and fixed.

Here, when the support pin 920 is inserted and fixed into the support pin fixing groove 930 , the front surface of the close contact support plate 900 is the back side of the blind support plate 100 in a state where the close contact support plate 900 is disposed on the crane pole. contact and support.

Therefore, when the crane 300 lifts a heavy object, the forward bending phenomenon can be supported by distributing the load by the blind support 100 and the close contact support plate 900 .

Furthermore, a rotating shaft 311 is formed at the lower end of the crane column 310 so that the crane 300 can move an object to a desired place by an operator, and the rotating shaft 311 is inserted so that it can be rotated. A rotation groove portion 332 is formed on the upper surface of the support portion 330 .

Here, a bushing or bearing may be installed inside the rotation groove 332 to rotate while supporting the rotation shaft 311 .

On the other hand, in order to smoothly guide the wire 200 pulling or unwinding in the crane 300, the bracket 340 in which the roller 320 is installed on the blind post 100 may be detachably installed.
