Abstract

The present invention relates to a jack for a communication cable drum, and an object of the present invention is to improve a moving means for driving a cable drum upwardly from the ground for easy take-out of a wound cable.

The subject of the present invention is a seating protrusion 32, 32 'on which the mounting member 31 is seated on the base 20, 20' placed on the pedestal 10, and a lifting body provided with a handle 33 at the top ( 30 is coupled to the piston 51 of the bottom hydraulic cylinder 50, while the piston and the elevating body are raised by one end of the plate 40.

That is, the present invention can achieve an easy ascension of the cable drum by the drum shaft is fitted to the mounting member, it is also easy to move the device by the wheel 70 of one end.

In other words, the present proposal can eliminate the waste of manpower, stamina consumption and safety accidents by using a simple iron holder of the prior art, and also has the effect of preventing damage to the cable drum and cable.

The present invention relates to a jack for a communication cable drum for easily pulling out the cable after mounting the drum wound up the communication cable to a predetermined position.

That is, the communication cable drum is not easy to move because the cable of the heavy weight is wound.

In addition, the coiled communication cable can only be pulled out when the cable drum is rotated and pulled out, so that the cable drum can be moved upwardly to be separated from the ground, and then the cable drum can be driven by mounting the drum shaft. Let's do it.

Therefore, in the related art, a cradle made of steel triangular supports (hand trucks) is disposed on both sides, and then drums are artificially lifted to mount both ends of the drum shaft to the cradle.

However, such work means requires a large number of working personnel to artificially lift the heavy weight cable drum, and in particular, it causes various safety accidents as well as heavy physical consumption.

Moreover, in consideration of drums of various sizes (diameters), there is a problem of having to manufacture cradles of various heights corresponding to them.

On the other hand, in some cases, such as pipes to the tires for the purpose of the cumbersome, manpower requirements and cost savings, such as to lay the cable drum so that the axis of the cable drum is laid in this case, in this case the drum frame It is often unreasonable to use because the tree is damaged and cannot be reused. In particular, the drum is poorly driven and the cable is not unsatisfactory, and the cable is damaged or the body is damaged. .

In view of the above-mentioned problems, the subject of the present invention is to provide a structural device which allows the drum to be simply moved upward by a synergistic action of a manual jack by a hydraulic cylinder.

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

The base 20, 20 'is placed on both sides of the upper surface of the pedestal 10, and fixed, but the inner end thereof, the mounting projection 32 of the upper and lower intervals facing each other so that the mounting member 31 can be seated (32 ') is formed to combine the lifting member 30 to be slidable up and down, the upper end of the lifting member 30 is coupled to the handle 33, the bottom of the hydraulic cylinder operated by one side plate (40) ( 50 is provided, and the piston 51 is welded and engaged, while the bracket 60 is fixed and installed at the front surface of the seat 10 in front of the wheel 70.

Reference numerals 80 and 80 'are reinforcement columns for firmly placing expectations, 90 is a cable drum, 90a is a drum shaft, and 100 is a communication cable.

In addition, the wheel 70 is located slightly protruded upward and slightly forward from the upper surface of the seat 10.

The operational effects of the proposed paper thus constructed are as follows.

The movement in this article uses the wheel 70.

That is, as shown in FIG. 5, when holding the handle 33 formed on the upper part of the device and tilting it toward the operator, the entire device is inclined at an angle while the wheel 70 touches the ground. When dragged or pushed while holding in a gripped state, its easy movement is achieved by driving the wheel 70.

In this way, the design is moved to the place where the cable drum (90), and then to the left and right around the cable drum (90).

Subsequently, the mounting member 31 is seated on the seating protrusions 32 and 32 'at the position closest to the point where the drum shaft 90a of the cable drum 90 is located, and then the step plate 40 is repeatedly stepped on the hydraulic cylinder. The piston 51 of 50 is raised, and the whole lifting body 30 is moved upward.

At this time, at the point where the position of the mounting member 31 seated on the seating protrusions 32 and 32 'coincides with the drum shaft 90a, the operation of the plate 40 is stopped to temporarily stop the movement of the lifting body 30. Then, the device of the present invention disposed on the left and right side is slightly moved to the cable drum 90 group, and both ends of the drum shaft 90a are inserted into the mounting member 31 inside.

When the operation is completed again by stepping on the back plate 40 repeatedly to raise the piston 51 of the hydraulic cylinder 50 and the lifting body 30 coupled thereto, the drum shaft 90a on the mounting member 31. The fitted cable drum 90 is gradually moved upward and falls from the ground.

That is, the cable drum 90 moved to the appropriate height from the ground in this way can be driven with the drum shaft (90a) as the axis, so that the easy extraction (unwinding) of the communication cable 100 is made.

Of course, if you want to put the cable drum 90 back on the ground after using the cable, operate the valve (not shown) provided in the hydraulic cylinder 50 in this paper to operate the piston 51 and the lifting body 30 at once. By lowering the cable drum 90 can be simply returned to its original position.

As mentioned above, this paper can move the heavy weight cable drum very easily and simply upside down by using the manual jack by the answer plate of this paper, so it consumes less physical strength and safely Work can be done without damage, while also having easy transportation by wheels.
