Description

Portable Lifting Rug

The present invention relates to a portable lifting lug that can be easily installed by lifting on a beam aggregate of a construction site or a heavy product of a factory.

In general, construction sites or factories use accessory materials such as bands or eye bolts to lift heavy materials manufactured in various shapes and sizes. In the case of such accessory materials, bands are easy to grasp the center of gravity and safely Although there is an advantage in that it can be lifted, the outer surface of the weight is lifted while the side of the band is wrapped there is a problem that the weight is damaged by the pressing force of the band.

Therefore, a method using an eye bolt has been used to solve the above problems.

Looking at the process of lifting the heavy object by using the eye bolt, first to drill the portion to be mounted the eye bolt, load the bolt portion formed at the bottom of the eye bolt to the perforated portion to weld the outer peripheral surface or to the lower nut Tighten and fix the wire rope to the upper side of the eye bolt.

When the eye bolt is lifted using the eye bolt as described above, the eye bolt is lifted by attaching only the eye bolt to a predetermined portion, so there is an advantage that it can be easily lifted without damaging the weight body, but most bolts are manufactured by the eye bolt hole. Since most of them are not, there is inconvenience that the user has to install by drilling the eye bolt hole.

In addition, when the eye bolt can not be mounted in the form of the heavy material, the wire sling is performed. If the center of gravity does not fit in the process of lifting the heavy material, the wire slewing part is deviated to the outside and at the same time the heavy material is separated. There is a safety problem that falls and causes a risk to the operator.

The present invention has been made to solve the above problems, it is possible to install in the place where the eye bolt is not installed in the heavy object to be lifted, in the process of lifting the heavy object by the connector installed so as to rotate on the clamp It is to provide a portable lifting lug that can be easily set by lifting the center of gravity generated.

The present invention for solving the problem to be solved,

A clamp body having a first arm having a fixed jaw to which the salvaged object is opposed, a second arm spaced in parallel with the first arm at a predetermined interval, and a second adjustable thread on the second arm of the clamp body A clamp having a pressure control rod coupled to press the salvaged object against the fixed jaw;

A connector body rotatably installed on the body of the clamp; It is achieved by a portable lifting lug, characterized in that it comprises a connector having a hook portion fixed to the connector body to wind the wire rope.

The present invention can be installed even where the eye bolt is not installed on the heavy object to be lifted, and the center of gravity generated in the process of lifting the heavy object can be easily set by the connector that is rotatably installed on the clamp. It is easy to carry, store and transport because the product is simple and compact.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The portable lifting lug 1 according to the present invention includes a first arm 111 having a fixing jaw 111a to which a lifting object is to be fitted, and spaced apart and parallel to the first arm 111 at a predetermined interval. Clamp body 110 having a second arm 113, and the length adjustment is threaded coupled to the second arm 113 of the clamp body 110 to pressurize the lifting object against the fixing jaw (111a) A clamp 100 having a rod 120; A connector body 210 rotatably installed on the body 110 of the clamp 100; It is composed of a connector 200 having a hook portion 220 is fixed to the connector body 210 so that the wire rope can be wound, as shown in Figs.

In the case of the clamp 100, in this embodiment, the first arm 111 and the first arm having a fixing jaw (111a) and one end of the first arm to be in close contact with the bottom surface of the wing piece 510 of the salvage 500 A horizontal bar 112 having a shaft hole 112a connected to the one side and connected in a horizontal direction, and one end thereof is connected to the other end of the horizontal bar 112, and is connected in the longitudinal direction to an outer surface thereof, and is threaded on an inner circumferential surface thereof. A clamp body (110) consisting of a second arm (113) having a formed nut hole (113a); The second body 113 of the clamp body 110 is rotatably installed in the pressure adjustment rod 120 is configured to reciprocate.

One side of the horizontal bar 112 to form a shaft hole (112a) to be able to communicate with the shaft hole 212 of the connector 200 to be described later.

In addition, the clamp body 110 is preferably formed of a metal material.

In the case of the pressure control rod 120 is rotatably fastened to the nut hole (113a) of the second arm 113, the present embodiment, the length to be fastened to the nut hole (113a) of the second arm 113 The threaded portion 121 is formed with an outer circumferential surface in a direction, and is formed at one end of the threaded portion 121 to form a bolt head 122 so that the threaded portion 121 can be rotated by a rotating means. At the other end of the screw 121 is rotated together in accordance with the rotation direction was composed of a movable jaw 123 to move forward or away toward the fixed jaw (111a).

In particular, the surface of the fixing jaw (111a) formed on the first arm 111 and the opposing surface of the movable jaw (123) mounted on the pressure adjusting rod (120) has an uneven surface formed roughly by knurling (specifically Not shown) was formed to prevent the wing piece 510 inserted between the fixed jaw (111a) and the movable jaw 123 to be separated from the lifting process.

In addition, the movable jaw 123 is rotatably installed at one end of the pressure adjusting rod 120 to rotate the pressure adjusting rod 120 to evenly pressurize the salvaged material 500 in a large area. .

In the case of the connector 200 in which the clamp 100 is loaded inside the front and the wire rope 600 is attached to the back, in the present embodiment, the shape formed in the predetermined thickness and viewed in plan is '⊂' type or 'c'. 'Shape formed to provide a space portion 211 so that the clamp body 110 is inserted in the rear, and the shaft hole of the clamp body 110 is inserted into both sides protruding from the space portion 211 ( 112a) and the connector body 210 is provided with a shaft hole 212 in communication with each other, and the hook portion 220 is installed on the front surface to be able to squeeze the wire rope 600.

The connector 200 is preferably formed of a metal material.

In addition, the shaft hole 212 of the connector 200 and the shaft hole 112a of the clamp body 110 were mounted to the shaft member 300 hinged rotatably.

By hinge-couple the shaft member 300 to the shaft hole 212 of the connector 200 and the shaft hole 112a of the clamp body 110 as described above, the lifting material 500 using the portable lifting lug 1.
