Abstract

The present invention relates to a split pin separating device for easily removing a split pin even in a narrow space.

The separating device includes a hollow support cylinder 40 having one end supported on the surface of the object 15 and a screw hole 41 formed at the upper end thereof; The jacket bolt 31 is screwed to the threaded hole 41 and the upper end thereof protrudes outward through the screw hole 41, and the hook 32 is fixed to the hook portion 22 at the lower end of the jacket bolt 31. A tow bar 30 formed with; It is provided with a wrench 50 coupled to the protruding end of the tow bar 30 to rotate the tow bar 30.

The separation device as described above includes a tow bar having a hook formed therein, a support cylinder for supporting the tow bar, and a wrench for rotating the tow bar, so that the wrench can be rotated even in a narrow space to safely and quickly separate the split pin. To make it possible.

Description

Split pin removing apparatus

The present invention relates to a split pin separating apparatus, and more particularly, to a split pin separating apparatus for removing a split pin easily even in a narrow space.

For example, when disassembling and repairing a compressor (Boil off gas compressor) operated at an LNG production base, the split pins for preventing loosening of the big end nut fixing the connecting rod and the crank shaft are removed. In this case, the space for the removal work is small due to the surrounding devices.

In addition, there is no suitable removal tool (Tool) to remove using a pliers and hammers (Hammer), but there is a problem that the work efficiency is lowered due to the limitation of the work space and excessive working time.

The present invention has been made to solve the above problems, it is an object of the present invention to provide a split pin separation device that can safely and easily remove the split pin even if the space is narrow.

The present invention to achieve the above object is in the split pin separation device for removing the split pin having a pin portion and a ring portion for holding the bonded object in the assembly,

A hollow support tube having one end supported on the surface of the object to be joined and having a screw hole formed at an upper end thereof;

A traction rod screwed to the screw hole and having an upper end protruding outwardly through the screw hole, and a hook formed at a lower end of the jacket bolt at a hook portion;

The wrench is coupled to the protruding end of the tow bar to rotate the tow bar.

The separation device of the present invention includes a tow bar having a hook formed therein, a support cylinder for supporting the tow bar, and a wrench for rotating the tow bar, so that the wrench can be rotated even in a narrow space to safely and quickly separate the split pin. To be able.

1 to 3 showing the split pin removing apparatus of the embodiment of the present invention, this is a connecting rod and a crank shaft during the overhaul of a compressor (Boil off gas compressor) operated at an LNG production base; It is used to separate the split pin 20 for preventing the loosening of the big end nut (15, hereinafter referred to as a to-be-adhered body) for fixing.

The assembly 10 and the object to be bonded 15 are held together by the pin portion 21 of the split pin 20 and are separated from each other through the ring portion 22 of the split pin 20.

Separation device according to an embodiment of the present invention is a hollow support cylinder 40, one end of which is supported on the surface of the object to be joined 15 and a screw hole 41 is formed in the upper end; The jacket bolt 31 is screwed to the screw hole 41 and the upper end thereof protrudes outward through the screw hole 41, and the lower end of the jacket bolt 31 is connected to the hook portion 22. The tow bar 30 is formed with a hook 32; The wrench 50 is coupled to the protruding end of the tow bar 30 to rotate the tow bar 30.

The wrench 50 includes a nut 52 coupled to the upper end of the tow bar 30 and a lever 51 serving as a handle.

Separation device of the configuration as described above, the hook 32 of the tow bar 30 is hooked to the hook portion 22 of the split pin 20 in a state in which the tow bar 30 is screwed to the support cylinder 40, When the wrench 52 is rotated while the nut 52 of the wrench 50 is coupled to the upper end of the tow bar 30, the towing bar 30 is rotated and moved upwards to separate the split pin 20. Will be.

The separation device as described above includes a tow bar having a hook formed therein, a support bucket supporting the tow bar, and a wrench to rotate the tow bar, so that the wrench can be rotated even in a narrow space to safely and quickly separate the split pin. To make it possible.

1 and 2 is an operation of the embodiment device of the present invention,

3 is an operation plan view of the wrench.
