Abstract

PURPOSE: A hook for lifting a pipe is provided to reduce the time for loading and unloading the pipe by catching the center of gravity of the pipe. CONSTITUTION: A hook is staple shape in order to form an insertion hole(3) between a connection part(1) of I-shape and a supporting part(2) of square A permanent magnet(5) is built in the inside part of the connection part. The permanent magnet excluding the open surface is surrounded with a non-magnetic material(4). When the both ends of the pipe are blocked for the cargo working of the pipe, the hook is attached to the right and left side of the pipe.

Description

Hook for lifting of pipe}

The present invention relates to a hook for pipe lifting, and more specifically, a straight connection portion and a right angled support portion having a connection hole are integrally formed in a "c" shape so that insertion grooves are provided therebetween, and an inner surface portion of the connection portion is provided. Permanent magnets are built into the pipes, and when a pair of hooks are attached to both ends of the pipes for the unloading operation of the pipes, the permanent magnets allow the hooks to be fixedly fixed without slipping from side to side. The present invention relates to a pipe lifting hook, which makes it easy to fit the center of gravity, thereby making the unloading work of the pipe quicker and safer.

In general, large pipes used for large diameter gas pipes, water pipes, etc. are bulky and heavy, so it is difficult to handle them when unloading. Therefore, large cranes that can lift the weight are mainly used. use.

In this case, a pair of hooks directly mounted on the pipe are connected to the wire to be installed in the crane to transmit the force of the crane. Such a conventional hook has a structure in which a straight connection part and a rectangular support part are integrally formed while forming a "c" shape such that insertion grooves are formed therebetween.

Therefore, the pipe can be lifted by operating the crane in a state where the pair of hooks are fitted to both ends of the pipe, respectively, so that the pipe can be easily unloaded.

However, such a conventional hook is not fully secured to the pipe when it is fitted to both ends of the pipe, so it is not easy to adjust the center of gravity of the pipe to be lifted as it slides easily from the upper end of the pipe to the left or the right. .

Therefore, it is very cumbersome and inconvenient to repeat the hooking operation of the hook a number of times or to hold the hook mounted on the pipe until the load is applied.

Accordingly, there was a problem that not only can not be quickly unloading pipe work, but also caused a safety accident during the unloading work of the pipe.

The present invention has been invented to solve the above problems, and in order to be able to be mounted in a fixed state when the hook is mounted on the pipe so that the unloading work of the pipe can be quickly and safely, In order to form a hook integrally formed while forming a "c" shape so that the right-angle support portion is formed between each other, the permanent magnet is embedded in the inner surface of the connecting portion except for the exposed surface, It is an object of the present invention to provide a hook for pipe lifting, characterized in that when mounted to both ends of the pipe for unloading work, it can be mounted in a fixed state without slipping from side to side.

The pipe lifting hook of the present invention is easy to grasp the center of gravity of the pipe as it is mounted in a fixed state when it is attached to the pipe by the permanent magnet, so that the unloading of the pipe can be made more quickly and easily. The safety accidents caused by heavy accidents can be prevented beforehand so that the unloading work of the pipe can be made safer.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

1 is a perspective view of the present invention, FIG. 2 is a cross-sectional view taken along line "A-A" of FIG. 1, FIG. 3 is a state diagram of use of the present invention, and FIG. 4 is a vertical cross-sectional view of "B" of FIG.

Pipe lifting hook 100 of the present invention is a hook integrally formed while forming a "c" shape so that the straight connection portion 1 and the rectangular support portion 2 is formed with the insertion groove (3) therebetween ( In the configuration of 100, the permanent magnet (5) surrounded by a non-magnetic material 4, except for the exposed surface of the inner portion of the connection portion 1 is built-in, the pipe (P) for the unloading operation of the pipe (P) It is characterized in that it can be mounted in a fixed state without slipping from side to side when it is attached to both ends of the).

The nonmagnetic material 4 serves to fix the permanent magnet 5 to the connection part 1 and to prevent the magnetic force of the permanent magnet 5 from being transferred to the connection part 1 to offset.

Reference numeral 6 in the drawings is a connection hole formed in the connection portion, W is a wire connected to the crane.

Pipe lifting hook 100 of the present invention configured as described above is connected to the wire (W) installed on the crane for the unloading work of the bulky and heavy pipe (P) is connected to both ends of the pipe (P) It is a tool that is geared to.

In particular, the pipe lifting hook 100 of the present invention can be mounted in a fixed state when mounted on both ends of the pipe P for lifting the pipe P, so that the center of gravity of the pipe P It is easy to carry out the unloading work of the pipe (P) effectively, as well as to prevent the occurrence of safety accidents in advance, it is a big feature that the unloading work of the pipe (P) can be more secure.

As shown in FIG. 1 and FIG. 2, the permanent magnet 5 which fixes the hook 100 to the pipe P magnetically is provided in the inner surface of the connecting part 1 which is in contact with the outer circumferential surface of the pipe P. It is possible by doing this.

As shown in FIG. 3, when a pair of hooks 100 connected to the wires W are fitted to both ends of the pipes P for loading and unloading of the pipes P, each hook 100 is connected to the pipes. It is attached in the state fixed to the edge part of (P).

That is, as shown in FIG. 4, as the permanent magnet 5 embedded in the inner surface of the connecting portion 1 and integrated with the hook 100 is attached to the outer peripheral surface of the end of the pipe P by magnetic force, the hook ( 100 is fixed to the end of the pipe (P).

Therefore, the hook 100 once mounted on the pipe P can maintain its mounting position as it is regardless of the load of the pipe P. That is, even if the pipe P is lifted to the upper side and the hook 100 is applied to the load of the pipe P or the pipe P is placed to the floor, the hook 100 is not loaded with the pipe P even though the hook P is not applied. The mounting position of 100) is maintained as it is.

Accordingly, when the hook 100 is mounted on the pipe P, the center of gravity of the pipe P can be accurately matched at once, and the center of gravity of the pipe P once fitted can be maintained as it is.

Therefore, it is not easy to properly adjust the center of gravity of the pipe (P) by sliding easily to the left or right in the state attached to the both ends of the pipe (P) because there is no configuration that plays the same role as the permanent magnet (5), It is possible to effectively solve the problem of the conventional hook that the safety accident was caused by the unbalanced load of the pipe (P).

Therefore, the hook 100 of the present invention makes the unloading work of the pipe P more quickly and easily, and prevents the safety accident due to the unloading of the pipe P, thereby making the unloading work of the pipe P safer.
