Description

Portable electric motion transfer equilibrator using rope}

The present invention relates to a portable electric transport device, and more particularly, to a portable electric transport device using a rope that is mounted on a rope to raise and lower a heavy load.

In general, various types of devices have been developed in order to transport a heavy load to a desired location by hanging it on a rope.

There is a cleaning device.

As shown in FIG. 1, such an automatic cleaning device is such that the winch 3 is mounted directly on the automatic cleaning device body 2, and the ropes 4 and 4' of the winding drum are wound or unwound to be transported to a desired position. are doing

However, in this case, in the case of an automatic cleaning device, the main body of the device is provided with a winding drum or a wand, so that the structure is complicated, and it is very difficult to repair it in case of failure.

Therefore, when using a device with a relatively heavy load, such as an automatic cleaning device, suspended through a rope, it is mounted directly on the rope rather than the device body to allow the device to be transported to a desired position while ensuring reliability according to the transport of the device. The need to develop a transfer device is emerging.

To this end, it is most important to develop a portable transport device using a rope that can minimize slippage by maximally providing a friction force between the pulleys supporting the rope when the rope transports a heavy load.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Advantages and features of the present invention and methods of achieving them before the description will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings.

The present invention is to provide a portable electric transfer device using a rope that is mounted on the rope to elevate and lower a heavy load. Therefore, the electric transfer device according to the present invention is installed directly on the rope, It should be understood that the object of the is raised and lowered by hanging on the electric transfer device installed on the rope.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 2 to 7 . For reference, Figures 2 to 5 (a) shows a preferred embodiment of the present invention, (b) is shown in an image for better understanding.

First, the present invention relates to a portable electric transfer device using a rope, as shown in FIGS. 2 and 3 , and largely, a power unit 10 , a gear unit 20 , a friction unit 30 , and a tension adjustment unit 40 ) is included.

The power unit 10 includes a motor 12 connected to an external power source or a separate battery (not shown) to operate, and a reducer 14 connected to the motor 12 .

Here, it is preferable that the reducer 14 uses a worm gear having a large reduction ratio to provide a self-locking function in which the worm does not rotate with the worm wheel. to prevent loosening.

Next, the gear unit 20 includes a driving gear 22 that receives power from the power unit 10 and rotates, and at least one driven gear 24 , 26 coupled to the driving gear.

According to an embodiment of the present invention, FIGS. 2 and 3 show that the driven gears 24 and 26 are provided on both sides around the driving gear 22, but the number of the driven gears is at least one or more. It goes without saying that it can be appropriately added to both sides of the driving gear.

Next, the friction part 30 is disposed to correspond to the driving gear 22 and the driven gears 24 and 26 of the gear part 20, respectively, and a plurality of pulleys 32, 34, 36 are axially coupled to rotate. ), and serves to impart friction between the rope and the rope, which will be described later.

That is, the rotational force transmitted to the driving gear 22 through the motor 12 and the reduction gear 14 is transmitted to the driven gears 24 and 26, and as a result, the pulley 32 shaft-coupled to the driving gear 22. And the pulleys 34 and 36 shaft-coupled to the driven gears 24 and 26 are rotated, respectively.

To this end, it is preferable to place a separate plate 6 between the gear unit 20 and the friction unit 30 to correspond to each other.

Next, as shown in FIG. 4 , the tension adjusting unit 40 is for adjusting the tension of the rope 4 drawn in from one end of the friction unit 30 and drawn out to the other end, and the tension adjusting unit 40 ) can be installed on both sides of the inlet or outlet side of the rope 4, and if necessary, of course.

Meanwhile, according to the present invention, as shown in FIG. 4 , a rope is wound around each pulley. At this time, the wound rope is at least on the outer peripheral surface of each pulley of each pulley in order to sufficiently impart friction between the rope and the pulley. It is preferable to be wound one or more times.

Here, the pulleys 34 and 36 located at one end and the other end are provided with a receiving portion 38 that allows the rope 4 to be wound crosswise, and in this case, the receiving portion 38 is a neighboring pulley. In order to facilitate the connection of 4), it is preferable to make the width of the rope 4 relatively wider than the diameter of the rope 4 by at least several times so that the rope 4 can be crossed in the receiving portion 38. .

According to the present invention configured as described above, as shown in FIG. 4 , the rope 4 is drawn into one end of the pulley 34 through the tension adjusting unit 40 and crossed in the receiving unit 38 while being wound at least one It is wound more than once, and then the neighboring pulley 32 is wound at least once, and finally, while being wound around the pulley 36 of the other end, it is also crossed in the receiving part 38 and wound at least one time or more and taken out. It is possible to use the frictional force as much as possible so that the rope 4 does not slide in the friction part 30 made of a plurality of pulleys by taking the shape of being wound, that is, the so-called 'figure 8 shape'.

That is, if a heavy load is hung on the device according to the present invention, the rope is pulled by the load, and as a result, a force to bring the pulleys into close contact with each other as shown in FIG. 4 is generated, thereby further increasing the friction force effect will occur.

Therefore, the sliding phenomenon of the rope in the friction part 30 hardly occurs, and even if it is assumed that the sliding phenomenon occurs, when a pulley constituting the friction part 30 is further added and coupled, the frictional force can be increased. In addition, when the tension of the rope 4 is adjusted by the tension adjusting unit 40 in addition to this, it is possible to make the pulleys more closely contact with each other, thereby maximally suppressing the occurrence of the slipping phenomenon.

In the present invention, as described above, a speed reducer 14 is provided between the motor 12 and the gear unit 20 to use a worm gear having a large reduction ratio, so that the worm does not rotate with the worm wheel. Self-locking function As long as the gear unit 20 is not rotated by the driving of the motor 12, the pulley on which the rope is wound rotates by itself, thereby preventing the rope from unwinding.

According to the present invention having the above configuration, it is possible to accurately and conveniently transport an object of a relatively heavy load according to the motor driving when transporting it through the rope, and also to wind the rope in a 'figure 8' shape on a plurality of pulleys. The structure is made very compact.
