Description

Line mark jig {LINE MARK JIG}

The present invention relates to a jig for line mark hitching, and more particularly, to a jig for line mark hitching, more specifically, to prevent a head mark from being deformed during a hitching process in order to install a line mark on a ground located above a buried pipe, To a jig for line mark hitching whose structure is improved so that holes and head holes can be drilled at the same time.

When a gas pipe, electric high-voltage line, telephone line or water pipe is buried, a line mark is installed on the upper side of the line so that the direction of the line buried in the ground can be confirmed.

1, the line mark 10 is composed of a head portion 11 having a guiding text on its surface and a fin portion 12 connected to the bottom surface of the head portion 11 and buried in the ground.

The installation of the line mark 10 is performed by first forming a perforation hole in the ground and inserting the fin portion 12 into the perforation hole and then mounting the head portion 11 with a hammer.

However, since the line mark 10 is made of mainly brass material and the width of the head part 11 is small, it is difficult to accurately mount the line mark 10 when hammering with the hammer, There is a problem that the pin 11 and the pin 12 are broken, and there is a problem that a safety accident occurs due to incorrect piling operation.

In addition, there is a problem that the line mark 10 is worn and damaged by directly hitting the line mark 10.

Conventional prior art for solving this problem has been disclosed in Korean Registered Utility Model No. 20-0436851 entitled " Line mark jig "(registered on October 22, 2007) A jig for a line mark for providing a line mark having a fin portion to be embedded in a perforation hole of an indicator, the jig comprising: a flange supported by the indicator at a lower end thereof, And a hinge rod slidably coupled to the inside of the fixed guide and having a lower end fixed to the head portion of the line mark and an upper end protruding to the outside of the fixed guide, The line mark is guided by the inner circumferential surface of the fixed guide and is embedded in the perforation hole.

As another prior art related to the conventional line mark installation jig, as disclosed in Korean Registered Utility Model No. 20-0456728 entitled " Line Mark Installation Jig "(registered on November 11, 2011) The upper frame includes a leg supporting the ground, an upper frame fixed to the upper portion of the leg and having a through hole formed therein, and a hinge portion moving up and down inside the upper frame hole and the leg, And has a groove shape on the side surface of the impact portion so as to be guided.

However, the conventional jig for installing a line mark has a problem that it is troublesome to perforate a hole formed in the ground so that the pin portion of the line mark is inserted into the ground and a head hole formed on the ground to accommodate the head portion of the line mark, The heavy jig has to be transferred and installed to the installation position on the line mark, so that there is an inconvenience in operation such as requiring a plurality of working personnel.

Korean Registered Utility Model No. 20-0436851 "Jig for line mark" (registered on October 22, 2007) Korean Registered Utility Model No. 20-0456728 "Jig for installation of line mark" (registered on November 11, 2011)

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to prevent the deformation of the head portion of the line mark in the process of mounting the line mark on the ground located above the buried pipe, There is provided a jig for line mark hitching, which is improved in structure so as to simultaneously perforate a hole and a head hole by a hitching operation.

In order to accomplish the above object, the present invention provides a disk-shaped body having a receiving groove formed in a bottom surface thereof to receive an upper portion of a line mark, a disk-shaped body having an outer diameter corresponding to the head portion of the line mark, A jig body portion having a cylindrical first connection port integrally extending from the outside of the plate-shaped body; A spring member having one end received and welded in the first connector; And a shaft member having a second connecting hole for receiving and welding the other end of the spring member to one side and a shaft body rotatable by being jointed to the other side of the second connecting hole, And a through hole is formed in the through hole to reduce vibrations generated when the hitting is performed.

A protrusion for forming a head hole is formed on a lower edge of the disc-shaped body.

In the present invention, the disk-shaped body indirectly transfers the impact force of the hovering tool to the head portion side of the line mark rather than directly to the head portion side, so that the pin portion of the line mark can be buried in the ground, .

In addition, since the present invention has the spring member formed with the through hole at the center of the disc-shaped body and connecting the jig body portion and the shaft member, it is possible to attenuate the vibration generated by the impact force applied to the disc- Respectively.

In addition, the present invention has an advantage in that it is possible to drill holes and head holes at the same time when hitting the disk-shaped body by using the hinge tool, thereby improving the work convenience. .

Further, since the shaft body of the present invention is jointly connected to the second connecting hole so that the shaft body can be rotated with respect to the joint, the operator has an advantage that the shaft member can be adjusted to a desired angle during the hitching operation.
