Description

A winder having a two-way wire flow device according to lifting and lowering {A Winder Having a Wire Mobile Unit of Two Direction}

The present invention relates to a winch having a bidirectional wire flow device according to the lifting and lowering, in particular the lifting and lowering, characterized in that the inner device is installed so as to expose the wire in both directions of the winch, and to take a load on all of the wire It relates to a winch having a bidirectional wire flow device according to.

In general, the endless winder (Endless Winder) is a device used to lift or lower the weight of the object, a number of conventional winding machine has been applied and used.

In other words, the hoisting machine is a machine that allows the wire rope or chain wound on the drum to pull the heavy object or lift the object using a pulley when the cylindrical drum is rotated. The drum is rotated by hand, and the brake is mounted so that the weight does not fall even when the crank is released. In addition, the large winch is driven by an internal combustion engine or an electric motor, and a clutch is formed between the gear and the drum to transmit or block power transmitted from the prime mover to the drum. To keep the weight in the desired position, release the clutch and apply the brake, and when unloading, release the brake. According to the number of drums, it is classified into single acting, double acting and multi acting, and it is widely used for transporting heavy goods in the factory, civil engineering, mining, and ship.

On the other hand, the conventional hoisting machine has only one roller provided with a pair of pulleys in the case, so when the radius of curvature is small, the fatigue of the wire increases, and there is a problem in that it easily ages, and also the wire tension cannot be adjusted. There is also a problem that twists easily, and furthermore, there is a big problem in safety because the friction force transmitted to the wire is weak.

In order to solve this problem, the applicant has proposed a wire tension control and twist prevention device (patent publication No. 2003-0085673) of a winch.

However, the present invention has a problem that the work efficiency is low because the load is applied only to one side and the other side is not loaded.

In other words, if there is only one line under load, if you move the upper part to the lower part, you need to move one object existing in the upper part to the lower part and move the lowered wire back to the upper part to move the upper part object to the lower part. There is a problem that the efficiency is very poor.

As a result, in the conventional hoisting device, only one wire is used at the time of moving an object, so that the use efficiency of the equipment is reduced and the working time is much longer.

The present invention is to solve the above problems, it is an object of the present invention to provide a device for the simultaneous operation in the bi-directional wire of the winch.

In addition, the tension control is made at the same time it is another object to enable a stable hoist work.

The present invention provides the effect of selectively using two wires exposed to the outside and working with both wires. This is different from that of the conventional hoist using only one direction of wire. By installing a weight on both directions of wire, the weight can be raised and lowered, thereby doubling the work efficiency, and thus the working time. It can be shortened.

In addition, by using a single-phase power source for the motor, it can be easily used even in places where a three-phase power source is not installed (eg, home).

In addition, there is an advantage that the management panel is integrated with the motor so that the control panel does not need to be manufactured separately and is easy to manage and can be used regardless of the place.

In addition, the wire is designed so that it does not slip from the pulley, thereby providing an effect of blocking the occurrence of a safety accident to the operator.

Looking at the operation of the present invention below.

The case 10 is provided with a pulley 30, and the pulley 30 is provided with a first roller chain 50 and a second roller chain 60. In addition, the first wire input / output guide part 70 and the second wire input / output guide part 80 are installed in an X-shape, respectively, in the lower part of the case 10, and one end of the first wire input / output guide part 70 is provided. It is coupled to the hinge pin 14 through the long hole 71 and the other end of the first wire input and output guide unit 70 is connected to the second roller chain 60 through the first chain connecting shaft 90.

It is connected with the first roller chain 50 through. Then, one end of the case 10, the motor 20 is installed, the shaft and the pulley 30 of the motor 20 is coupled to the pulley 30 is fixed in accordance with the clockwise rotation or counterclockwise rotation of the motor Rotate and reverse.

According to the present invention, the wire input / output holes 12 and 13 are formed at the lower part of the case 10, and the wire at one end is inserted through the one wire input / output hole 12 among the wire input / output holes 12 and 13. After winding one round on the pulley 30, the wire is exposed to the outside through the other wire input / output hole 13. Then, a total of two wires 12 and 13 are exposed to the outside.

In addition, the wires 41 and 42 are respectively coupled to the weight bar, one wire 41 serves to lift the weight body, the other wire 42 serves to lower the weight body. .

An operation occurring inside the case 10 will be described in more detail.

First, 41a represents an extension wire of the first wire 41 extending from the first wire to wrap around the pulley, and 42a represents an extension wire of the second wire 42 extending from the second wire to wrap around the pulley. Indicates.

Looking at the operation of lowering the first wire 41 and raising the second wire 42, the first wire 41 is moved in the direction in which the wire 41 is tightened while being subjected to the gravity load by the weight body. Then, as the long hole 71 is pushed behind the hinge pin 14, the entire first wire input / output guide unit 70 is pushed backward, and at the same time, the first chain connecting shaft 90 connected to the first wire input / output guide unit 70. ) Is pushed backward and the wire 42a surrounding the pulley 30 is strongly pressed onto the pulley.

That is, when the first wire 41 is lowered, the extension wire 42a of the second wire 42 spanning the first chain connecting shaft 90 is in close contact with the pulley.

At this time, when the pulley 30 is rotated by operating the motor 20, the force is operated by the first tension roller 110 in a direction opposite to the direction in which the wire 41 moves, so that the wire 41 is the first tension roller. It is possible to easily descend by riding the 110, since the first chain connecting shaft 90 is a state in which the wire 42a is strongly pressed against the outer periphery of the pulley 30, the wire slips from the pulley 30. Will be prevented.

If the wires 41a and 42a are not strongly adhered to the pulley 30, the wires may slip due to the gravity load of the weight body, causing the wires to slip. May occur.

In order to solve the problem, the present invention is to force the wire (41a) 42 by pressing the wire (42a) while the first chain connecting shaft 90 is automatically moved when a load is applied to the wire (41) by a weight body To prevent it from vanishing.

On the other hand, during the operation of loading the heavy body on the first wire 41 and lowering at the same time can carry out the operation by lifting the weight on the second wire 42, the second wire 42 also due to the weight When a load is generated and a load is generated on the second wire 42, the second wire input / output guide unit 80 is retracted backward and the second chain connecting shaft 100 retreats backward in association with the first roller chain 50. ), The wire 41a is tightly pressed against the pulley 30.

Accordingly, the wire 41a is prevented from slipping and at the same time, the second tension roller 120 provides the elastic force to the wire 42 so that the wire 42 can be easily lifted.

Of course, it is also possible to transfer the weight using only one of the first wire 41 or the second wire 42, and then the unloaded wire only serves as an auxiliary to move the wire. In addition, the wire under load becomes taut and the wire can be raised or lowered without the sliding of the pulley by the action of the tension roller and the chain connecting shaft.

As a result, according to the present invention, the lifting and lowering of the weight body may be simultaneously performed within a predetermined load by using the two wires 41 and 42, and the lifting or lowering of the weight body using only one wire as necessary. It provides the advantage to proceed with the descent work.
