Abstract

(57) [Abstract] [Purpose] Lifting is extended because it can be used according to the height of the object to be lifted from the beginning when moving or installing heavy objects, machines, etc. Perform efficient and safe work. An elevating body 3 in which rack-shaped engaging portions 5 are formed on both inner sides of a vertically elongated opening 4 formed in the front surface, and a rack-like fitting portion adapted to the engaging portion 5 of the elevating body 3. And a detachable claw 6 having 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jack used for moving heavy objects, machinery, etc., installation work, etc., which is easy to handle and can adjust the lift steplessly. It is characterized by being able to.

[0002]

[Prior Art]

 Conventionally, in jacks used for moving heavy objects, machines, etc., installation work, etc., an elevating body and a pawl are integrally formed.

Therefore, in the case where the presentation is insufficient, a stand is separately provided under the jack.

[0004]

[Problems to be solved by the device]

 As described above, in the conventional jack with limited lift, when lifting a heavy object, a machine, or the like from a certain height position, the lift may not be used as it is.

Therefore, although the base portion is separately configured, it is troublesome and attention must be paid to prevent the base portion from collapsing.

The present invention has been made in view of the above circumstances, and it is efficient and safe because the jack can be fully lifted from that point according to the height of the object to be lifted. The purpose is to provide a jack that can perform various tasks.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an elevating body having rack-shaped engaging portions on both sides inside a vertically elongated opening, and a rack adapted to the engaging portion of the elevating body. The claw-shaped fitting portion is detachable.

[0008]

[Action]

 According to the present invention, it can be used according to the height of an object to be lifted from the beginning in moving heavy objects, machines, installation work, and the like.

Therefore, the so-called jack lift is not limited, and the lift of the jack can always be effectively used, and the rack-shaped engaging portion and the fitting portion are configured. By doing so, stepless adjustment is possible and efficient and safe work can be performed.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view of a jack according to the present invention, and FIG. 2 is a front view thereof.

Reference numeral 1 is a base portion, which is configured to have an appropriate width and length, and a jack body 2 is erected at a substantially central portion of the upper surface.

Although not shown, the jack body 2 has a built-in ram configured to move up and down by hydraulic pressure.

Reference numeral 3 denotes an elevating body, which covers the front surface, both side surfaces and the upper surface of the jack body 2, is attached to the ram, and is configured to move up and down by the ram.

In the present invention, a vertically long opening 4 is formed on the front surface of the elevating body 3, and rack-shaped engaging portions 5 are formed on both sides of the opening 4.

As shown in the drawings, 6 is a claw, which is formed in a substantially L-shape on the side surface, and the horizontal portion 6a serves as a support portion for heavy objects and the vertical portion 6b moves up and down. It is configured to fit with the engaging portions 5 formed on both sides inside the opening 4 of the body 3.

That is, rack-shaped fitting portions 7 are provided on both sides of the vertical portion 6b.

Reference numeral 8 denotes an elevating lever. When the elevating lever 8 is repeatedly pushed downward, the lifting body 3 is raised by the ram, and conversely, the lifting lever 8 is lifted upward to lift the lifting body 3. It is configured so that it can be lowered.

Further, the elevating lever 8 can be rotated 360 degrees in the horizontal direction, and can be operated from any direction regardless of the work place or the like.

Reference numeral 9 in the drawing denotes a handle for carrying.

In the present invention having the above-mentioned configuration, the claw 6 is fitted to the engaging portion 5 of the opening 4 of the elevating body 3 according to the height of the object to be lifted in advance. After that, the elevating body 3 may be raised to a required position.

That is, according to the present invention, since the claw 6 is detachably attached to the elevating body 3, a predetermined lift can always be obtained from the initial height position, and a heavy object, a machine or the like can be placed at a desired position. You can easily lift up to.

[0023]

[Effect of the device]

 According to the present invention, it can be used according to the height of the object to be lifted from the beginning in the movement of heavy objects, machines, installation work, etc., and the same effect as when the lifting is extended is obtained. It is possible to perform efficient and safe work.
