Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention installs an expansion and contraction pipe equipped with an arm and a wire rope hoist on the floor and ceiling where it is desired to hoist, and hoists and lowers materials such as piping. The present invention relates to a portable lifting machine that serves as an auxiliary support for horizontal and centering.

[0002]

[Prior art]

(A) For small-diameter piping work indoors, one person should hold one side of the pipe and the other should be tightened or welded by one person to the pipe bracket that was previously attached. (B) However, if it is difficult to install the piping bracket first, or if accuracy such as slope and level is required, one person should look for the temporary suspension of the pipe and hold it, and the other one should tighten it. Temporarily suspend the suspension core while adjusting the horizontal level. By doing this, the pipe bracket dimensions are measured, manufactured, and attached. (D) When there is no temporary suspension receiver, press the temporary pipes together, measure the bracket dimensions while making the horizontal, etc., and then manufacture and attach. As mentioned in (a) above,
Attach the pipe again.

When a conduit or the like is to be piped along a wall surface, an auxiliary member presses the pipe, and the pipe is leveled and fixed to the wall with a saddle.

Mounting of a wall-mounted operation panel or the like is carried out by scribing, drilling, and adjusting the mounting, but in most places there is no hanging support, and two or three people must lift and hold it twice.

When working on a ladder, one person holds it down and the other hangs a safety belt on top, but in most cases there is no storage space for tools and materials at the top, and to prevent it from falling, try as much as possible. Put it down so that it doesn't attach to it, and lift it up and down each time.

[0006] In many cases, a machine is held to hold and machine a horizontal wall of a concrete wall for drilling and chipping.

[0007]

In the conventional work mode,
Since small-diameter pipes and those that can be lifted by human power do not use chain blocks or the like, they do not have suspension supports, and it takes more labor and time than necessary for accurate temporary suspension. In addition, there is no use for the personnel who just hold it down.

Where the surrounding humidity is high, or when one person holds one side of a pipe or the like and the other person welds it while the body is wet with sweat, rain, etc., the holding side becomes an electrical earth and there is a danger of falling off. There is a nature.

Repeated steps of climbing up and down the ladder and hanging the safety belt lead to troublesome operations such as throwing tools and members, which is a waste of labor and time.

Since work such as drilling and chipping of a wall also adds to the weight of the machine, it causes fatigue even in a short time.

The present invention has been made for the purpose of efficiently improving the above-mentioned drawbacks, and a provision of a temporary suspension receiver at a necessary place is provided to provide a portable hoisting machine which can easily perform height adjustment and hoisting. It is what

[0012]

[Means for Solving the Problems]

(A) In order to achieve the above-mentioned object, the telescopic protrusion-supporting type portable hoisting machine according to the present invention includes a pipe split metal fitting capable of incorporating a pull-out prevention pipe in stages and fixing the pipe at a free length. An expansion and contraction pipe with a slightly inclined level adjuster with anti-slip rubber for adjusting the tension on both ends and an arm mounting hole seat on the top. (B) Attach the arm with the sheave and hook hooking metal fitting sandwiched between flat plates such as aluminum to the arm mounting hole seat with the removable pin bolt. (C) The hoisting wire rope hoisting machine is fixed to the expansion / contraction projecting pipe base body with the tube fittings, and the wire rope is provided at the tip of the wire rope through the arm sheave. (D) Further, an arm tensioner for adjusting the angle of the arm is attached between the arm and the hoist for hoisting.

[0013] Further, a flexible hook is provided which can be freely mounted between the suspended wire ropes of the expansion / contraction supporting mobile lifting machine.

[0014]

With the above-described portable extension hoisting support type, if there is a ceiling slab, a beam, etc. on the upper part, the telescopic extension pipe can be freely pushed from the floor, and a small space is needed at a necessary place. Can be installed easily. In addition, even if the upper and lower ground contact surfaces are slightly inclined, the level adjuster with rubber is used to support the inclination adjustment.

Further, the horizontal and vertical angles of the arm can be freely set to avoid surrounding obstacles such as a stepped ceiling.
It is also installed along the wall. Further, when the arm tensioner is attached to the arm and the hook fixed on the floor, the fulcrum is stabilized.

Since the wire rope hoist for hoisting is provided with both the up and down brakes, level adjustment and hoisting can be easily and safely performed. Since the hoisting handle is attached with a flat type jet or spanner so that it can be detached, it does not become an obstacle, and the arm tensioner is the same.

Further, since the universal hook can be easily attached to any position of the suspended wire rope, the pipe or the like in the middle or at the rear can be easily suspended and adjusted.

At the time of storage, if the level adjuster at the end of the expansion / contraction pipe is rotated and removed, and the arm mounting pin bolt is removed to separate the arm, it is easy and convenient to store.
