Abstract

The present invention relates to an auxiliary device of a hydraulic jack, the inner case of the "C" shaped cross section is formed on the base to form the cutting groove is formed in the upright state on the base is formed so as to face each other inside the case. The lower body is formed with a dovetail groove, and the outer case having a flat "C" shaped cross section is formed on the top of the inner case in a state where the debtail protrusion is formed so as to be engaged with the dovetail groove in the upper portion of the lower body is formed; The support part is formed and provided as an upper body with a support piece extending in the horizontal direction at the bottom thereof so that the hydraulic jack is interposed between the upper and lower bodies, and according to the height of the lower surface of the workpiece to be lifted to the upper body. It is characterized in that the height compensation means is provided to compensate for the height of the support piece.

The present invention is stable without lifting the upper body is rotated and safety accidents are reduced and can be separated into a plurality of props easy to move, of course, can be used to replace only the hydraulic jack in the event of a failure of the hydraulic jack, the support piece is located at the bottom of the workpiece The piston rod can be raised after performing the height compensation as much as possible, so that the work can be performed without any effort in which the upper body is lifted under no load, thereby improving work efficiency.

Claims (5)

The bottom body is formed in the inner case of the "C" -shaped cross-section so as to accommodate the cylinder in an upright state on the base formed with the cutting groove and the bottom body having a dovetail-type groove formed in the inner side of the case to face each other, and the plane A dovetail protrusion is formed to be coupled to the dovetail groove in a state where the outer case having a “c” shaped cross section is covered on the outside of the inner case, and a support part is formed at an upper end thereof, and a support piece is horizontally formed at a lower end thereof. An auxiliary apparatus of a hydraulic jack, which is formed to be extended to the upper body, and is configured to be used through an ordinary hydraulic jack between the upper and lower bodies. The auxiliary jack of claim 1, wherein the upper body is provided with height compensating means for compensating by adjusting the height of the upper body and the support piece according to the height of the workpiece. The hydraulic jack of claim 2, wherein the height compensating means comprises a locking hole formed by a plurality of stages on one side of the upper body, and a separate workpiece support having a locking jaw formed thereon to selectively hang on the locking hole and having a support piece formed at a lower end thereof. Auxiliary device. 3. The hydraulic jack auxiliary device according to claim 2, wherein the height compensating means comprises a pinhole formed in multiple stages on the upper body, and a height compensating pin penetratingly coupled to the pinhole. According to claim 1, wherein the lower body is formed in the center of the base having a cut groove is formed in a flat parallel parallel cross-sectional partition wall for receiving a normal hydraulic jack and the partition wall has a dovetail type groove and the upper body in the inner side facing each other An inclined surface is formed on the upper part so as to be caught by the inclined locking jaw, and the upper body has a dovetail-type protrusion formed to be coupled to the dovetail-shaped yaw on both sides thereof by a support section and a support piece on the side. A hydraulic jack auxiliary device is provided with a rigid locking jaw formed to be caught on the inclined surface of the lower body. ※ Note: The disclosure is based on the initial application.
