Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endless type winding machine that winds a wire rope once around a single sheave gear and is suitable for towing a gondola for lifting and lowering.

[Conventional technology]

In general, there are known winding machines of the drum type, in which the wire rope is wound several times around a drum, and the endless type, in which the wire rope is wound approximately several times around a sheave.

As mentioned above, unlike the drum type winder, the endless type winder only wraps the wire rope around one sheave gear once, so the winding of the wire rope interferes with each other at the end and the winding at the outlet. , the wire rope gets frayed.

In order to avoid this, various methods have been devised in the past, such as placing the exit of the wire rope at the top of the winder where it will not interfere with the human body, and extending it outside from the top of the wire rope winder to prevent interference, or The outlet is located at the bottom of the winder.

On the other hand, an endless type winder generates holding force through friction between the sheave gear and the wire rope, and this can be done by applying pressure to the sheave gear of the wire rope in a distributed manner or by concentrating pressure locally. There is a way. The method of distributing pressure on the wire rope is to arrange a chain around the outer circumference of the sheave gear, attach a lever to one end of this chain, apply a hanging load to this lever, and displace the lever with the hanging load to move the chain in the direction of the sheave gear. is being assisted by.

Furthermore, conventional sheave gears have a groove in the center of the outer circumference, and the wire rope is wound around this groove, and when the wire rope is wound around the sheave gear, dust that adheres to the outer circumference of the wire rope overflows from the groove and is emitted outward. A dust ring is usually provided to prevent this dust from entering the gear case.

Furthermore, in the conventional winding machine, a gear mechanism is interlocked with the output shaft of the motor via a coupling, and this gear mechanism drives the sheave gear in forward and reverse rotation.

[Problem that the invention seeks to solve]

However, the winding machine having the above structure has the following problems.

In order to prevent the wire rope entrance and exit from interfering with the tooth 1, if the exit is provided at the top or bottom, a complicated deflection fitting is required, the structure is complicated, installation is difficult, and replacement is difficult. Have difficulty.

The method of pressing the wire rope locally in order to create friction between the sheave gear and the wire rope in the spear 2 causes a large amount of wear and tear on the wire rope and is inferior in durability. Further, when applying a hanging load to press the wire rope in a distributed manner, for example, if a gondola or the like that generates the hanging load is on the ground, no hanging load is generated.

For this reason, during the initial operation when no hanging load is generated, there is little friction on the wire rope (it may not operate smoothly).

Providing a dust ring or the like to prevent dust from the wire rope from entering the fangs 3 complicates the structure and requires difficult maintenance.

If the output shaft of J'4 is connected to a gear via a coupling, the number of parts will increase due to the coupling, and the mounting space will become larger, the weight will be heavier, and the cost will increase.

Therefore, an object of the present invention is to prevent wire rope interference with a simple structure, to always apply a constant frictional force to the wire rope even when there is no hanging load, and to remove dust from the wire rope with a simple structure. To provide an endless type winding machine which can be easily operated, does not require a coupling, has a simple and compact structure as a whole, and is inexpensive.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a structure in which a rope duct is provided close to the sheave gear, and one end of the rope binder that presses the wire rope is always held together via a spring. It is characterized by forming an annular groove along the circumferential direction on the outer peripheral end of the sheave gear, and further forming a gear on the output shaft and directly connecting it to the gear mechanism.

[For production]

Because the outlet end of the wire rope is inserted into the rope duct, it does not interfere with the wire rope on the entrance side, and since the spring is constantly pulling the rope binder, the wire rope is pressed against it even when there is no hanging load, and the wire rope is pushed along the annular groove. The dust on the wire rope is discharged, and the output shaft directly drives the gear mechanism.

〔Example〕

An example of implementation of the present invention will be described below with reference to the drawings.

The winding machine A has a motor 10, gear cases 8α and 8A, and an operation box 9.

The motor 10 is rotatably provided with an output shaft 1), and a gear 1) fZ is formed on the outer periphery of the output shaft 1).
) the gear mechanism is directly driven via a.

A gear mechanism is built into the gear cases 8α and 86. That is, a motor gear 12 meshes with the gear 1)a, a main shaft 14 is connected to a drive shaft 13 of the motor gear 12 via a brake gear, and planetary gears 15 and 16 are rotatably meshed with the main shaft 14.

A sheave gear 7 is rotatably provided in the center of the gear case 8α via bearings 17 and 18, and a gear 18 provided on the inner periphery of the sheave gear 7 meshes with the planetary gears 15 and 16, thereby increasing the output of the motor 10. The power of the shaft 1) is transmitted to the sheave gear 7 via a gear mechanism.

A rope annular groove 19 having a V-shaped cross section is formed at the center of the outer periphery of the sheave gear 7, and the wire rope 2 is wound approximately one turn around the rope annular groove 19.

Approximately 4 times is not the entire circumference of the annular groove 19 for the rope, but 4 times around the outer circumference.
It is wound so that it is in contact with the third part. However, it can also be used by wrapping it around the entire circumference.

The outer peripheral end of the rape gear 7, in other words, the annular groove 1 for the rope
90 Two annular grooves for dust along the circumferential direction on both sides 20.
20 is formed, and the dust adhering to the wire rope 2 overflows from the rope annular groove 19 into the dust annular groove 20 during the rotation of the sheave gear 7, and further flows into the dust annular groove 20 as the sheave gear 7 rotates. is discharged to the outside.

Therefore, even if the gear cases 8α, 8b are not provided with dust rings or the like, dust does not enter the gear cases 8α, 8A, and clogging and the like are prevented.

The gear case 8α is provided with a wire rope artificial side guide pipe 21, and the wire rope 2 suspended from the upper fixed member is inserted into this guide pipe 21 and wound around the rope annular groove 19 of the sheave gear 7. There is.

Similarly, the gear case 8α is provided with a rope duct 1 on the exit side of the wire rope 2 at a position close to the sheave gear 7, and the exit end of the wire rope 2 exiting from the sheave gear 7 passes through the rope duct 1 inside the rope duct 1. is inserted, and the other end extends outside in an unloaded state.

The rope duct 1 is composed of a square or cylindrical pipe consisting of a trumpet-shaped artificial part 1α, an intermediate curved part 1h, and a lower vertical part IC. The inlet part 1a opens at right angles to the upper part of the sheave gear 7, and the wire rope 2 coming out from the upper part of the sheave gear 7 enters the inlet part 1α.
It is deflected by contacting the inner circumferential side surface thereof, further abutting the inner circumferential upper surface of the curved portion 1h, deflected along the curve, and guided by the curve to the vertical portion IC.

The outer end of the wire rope 2 is on the slack side, and there is no tension due to the load, so there is almost no wear on the rope duct 1, and there is little wear on the wire rope 2 itself.

The artificial side of the wire rope 2 is guided vertically to the sheave gear 7 by a guide pipe 21.

On the other hand, the outlet side of the wire rope 2 passes through the inside of the rope duct 1, and the curved portion 1h and the vertical portion IC of the rope duct 1 are located eccentrically from the sheave gear 7. Therefore, the inlet wire rope 2 and the outlet wire rope 2 entering from the vertical direction do not interfere with each other, are not worn out by friction, and the wire rope 2 moves smoothly. With the rope duct 1, the wire ropes 2 will not interfere at the intersection even without the guide pipe 21.

A rope binder 5 is provided that runs along approximately half the circumference of the sheave gear 7. One end of the rope binder 5 is fixed to the gear case 8α via a pin 5g, and the other end is fixed to the shaft 23 of the sheave gear 6 via a link 22. coupled to lever 6
As the rope binder 5 rotates in the direction of arrow Y, the rope binder 5 is pulled in the same direction, and the inner circumference of the rope binder 5 presses the wire rope 2 against the sheave gear 7 with a constant pressing force. Therefore, the desired friction is generated between the wire rope 2 and the sheave gear 7 due to this pressing force, and the sheave gear 7
When the winding machine A rotates forward or backward, the wire rope 2 rotates in the same direction and expands and contracts, thereby causing the winding machine A to move up and down.

Therefore, gondolas and the like suspended from the winder A move up and down in the same direction.

The lever 6 is rotatably supported by a central shaft 24, and the spring 3 is connected to the lower part of the lever 6 via a pin 25. Similarly, a load such as a condoler and other suspended members is detachably attached to the support @26. Let it go.

One end of the spring 3 is connected via 27 to a spring adjustment member 4 consisting of a bolt, nut, etc., and by adjusting the length and stroke of the bolt, etc., the spring load of the spring 3 is adjusted to correspond to this spring load. rope pine tick 5
In other words, the pressing force of wire rope 2 and sheave gear 7
This causes friction between the parts.

The spring 3 always pulls the lever 6 in the X direction, which causes the lever 6 to displace in the Y direction about the central axis 24, and also pulls the rope binder 5 in the Y direction, so there is always a gap between the wire rope 2 and the sheave gear 7. A certain amount of friction is occurring.

For this reason, if, for example, a gondola or the like is suspended from the shaft 26, the bar 6 further rotates in the Y direction and generates more friction, but if no load is applied to the shaft 26, for example, when the winding machine A is Even if the load such as a gondola is placed on the ground, a minimum amount of friction is generated by the spring 3, so raise the winder A. Even in the initial stage, the wire rope 2 is biting into the sheave gear 7. It works well.

The rope binder 5 is composed of chain rollers, belts, etc. of arbitrary length, and the inner periphery of these members presses the wire rope 2 in a distributed manner.

Since the operation box 9 is integrally assembled to the lower part of the gear cases 8α and 8b and incorporates an electric system, the entire winding device is housed in one place, making it compact and improving operability.

〔Effect of the invention〕

According to the present invention, the following effects are achieved.

■An annular groove for dust is formed on the outer periphery of the sheave gear, so the dust that adheres to the wire rope is guided outside and discharged along this groove, eliminating the need for dust-proof members such as dust rings, and reducing the number of parts. The structure is compact.

■Since the rope duct is provided close to the sheave gear, the artificial side and outlet side of the wire rope do not interfere, so the wire rope does not get abraded, improving its durability. Furthermore, since the rope duct is an integral pipe, it has a compact structure, requires less space for installation, and is easy to replace if damaged.

■Since there is a rope binder that presses against the wire rope sheave gear side, a certain amount of friction is generated between the wire rope and the sheave gear, preventing the wire rope from slipping and improving the traction ability.

■The rope binder is always pulled in a fixed direction by a spring, and a fixed pressing force is always generated on the rope binder. Therefore, even in the initial state where no hanging load is applied to the winding machine, the wire rope bites into the sheave gear and the initial operation can start smoothly. Moreover, by adjusting the tension of the spring, it is possible to generate friction between the wire rope and the sheave gear in accordance with the hanging load.

■A gear is formed on the output shaft, and the gear mechanism is directly connected via this gear, so there is no need for couplings or other connecting members, and the valve structure is simple, requiring less space and making it more compact. .
