In this case, the rope is raised and lowered, the first roller rotates in a counterclockwise direction, the second roller rotates in a clockwise direction, and when the pulley portion rotates counterclockwise with respect to the axis of the pulley portion, the rope descends and the first The roller rotates clockwise, and the second roller rotates counterclockwise. For this reason, the first roller and the second roller simultaneously rotate in opposite directions to the lifting or lowering direction of the rope, thereby improving the amount of foreign matter removed from the surface of the rope.

In general, in elevators, cranes, hoists, machinery, etc., grease is applied to the wire rope surface to extend its life and increase efficiency.

In particular, the rope of the high-speed elevator plays an important role in connecting the hoisting machine and the main body to transport, and grease is applied to the surface of the rope to extend the service life of the rope by reducing frictional force and load on the rope used in the elevator. .

At this time, a rope used in a high-speed elevator may have a significantly lower service life than that of a general elevator.

Accordingly, a task of periodically applying grease to a rope used in a high-speed elevator is performed. However, since the amount of grease applied to the rope surface may vary depending on the operator, there is a problem that the grease on the rope surface is not constant.

In addition, the grease applied to the rope surface tends to become thinner over time, the coated surface becomes grooved, or the grease deteriorates and the effect of preventing corrosion decreases, so the surface of the wire rope is periodically cleaned and new grease. There is a need to apply.

Particularly, in the pulley where part of the rope is wound, foreign substances (sludge) such as dust, dust and old grease are deposited on the rope surface, causing the rope to escape, so it is necessary to remove the grease from the elevator rope. The problem that the safety of the worker is threatened is emerging as the work is carried out manually by the worker.

Therefore, foreign matter (sludge) adhered to the elevator rope surface must be removed. Until now, related technologies have not been developed for devices (equipment) for this purpose, and the structure is particularly simple while effectively removing the adhered foreign matter (sludge). No removal device has been proposed for easy operation.

In addition, due to the characteristics of elevator ropes that require continuous movement, it is difficult to install the device on a fixed wall, such as a wall, to remove grease, so there is a problem that the efficiency of work is deteriorated.

Accordingly, there is a need for development of a sludge removal device for elevator ropes that corresponds to the surface of the rope to remove foreign matter (sludge) and has a simple structure to facilitate operation and to increase work efficiency.

Rope(10) Pulley part (100) First roller (410) 2nd roller (420) Up CW CCW CW Down CCW CW CCW

Referring to Tables 1 and 5, if the control unit 800 receives a signal for the rotation direction of the pulley unit 100 from the encoder 200 or the motion sensor 300 in a clockwise direction (CW), Recognizing that the rope 10 rises, controlling the first rotary motor 510 to rotate the first roller 410 counterclockwise (CCW), and the second roller 420 clockwise (CW) It is possible to control the second rotary motor 520 to rotate.

In addition, the control unit 800 recognizes that the rope 10 descends when a signal for the rotation direction of the pulley unit 100 is received from the encoder 200 or the motion sensor 300 in a counterclockwise direction (CCW). And, the first rotation motor 510 is controlled so that the first roller 410 rotates in a clockwise direction (CW), and the second rotation motor 520 so that the second roller 420 rotates in a counterclockwise direction (CCW). ) Can be controlled (see Fig. 6).

Accordingly, since the first roller 410 and the second roller 420 are rotated in the direction opposite to the moving direction of the rope 10 by the control unit 800, a structure is formed in which the first roller 410 and the second roller 420 are rotated and scraped in the opposite direction to the rope 10, The effect of removing foreign substances attached to the outer surface of the rope 10 may be maximized.

In addition, the first roller 410 and the second roller 420 are provided with respective first brushes 411 and second brushes 421 coupled along the outer surface.

At this time, the first brush 411 and the second brush 421 can remove foreign substances in close contact with the outer surface of the rope 10, including various types of known brushes, and the first brush 411 ) And the second brush 421 is preferably provided with a first brush hair 4111 and a second brush hair 4211 having a predetermined angle from the surface of the first brush 411 and the second brush 421 Do.

The rope 10 undergoes a twisting operation of twisting a plurality of ropes such as ordinary twisting or langue twisting in order to improve tensile strength, fatigue life, and abrasion resistance, so that a diagonal groove exists on the outer surface of the rope 10. , A foreign material is deposited along the diagonal groove (see FIG. 7).

Therefore, the first brush hair 4111 and the second brush hair 4211 are the surfaces of the first brush 411 and the second brush 421 so as to correspond to the diagonal grooves of the rope 10 formed by the twisting operation. Having a predetermined angle from, there is an effect of improving the removal amount of foreign matter deposited on the outer surface of the rope 10.

In this case, in the present invention, the first roller 410 and the second roller 420 are characterized in that they can be moved in the longitudinal direction by the connection part 700.

One end of the connection part 700 is combined with the length motor part 600, and the other end is combined with the first roller 410 and the second roller 420 at the same time.

In other words, the connecting portion 700 is in the form of a'Y' jack, one end has one end and the other end has two ends, respectively, the first roller 410 and the second roller at the other side of the connecting portion 700. Each of the 420 is combined to have the advantage that the first roller 410 and the second roller 420 can independently move.

With reference to FIG. 4, the connection part 700 will be described in detail.

The connection part 700 is provided with an outer shaft 710, an inner shaft 720, and a support shaft 730.

The outer shaft 710 is a cylindrical shaft, and the other end has a diameter different from that of one end, and when the end faces from one end to the other end, an end is formed at one point. Further, the other end of the outer shaft 710 is inserted into the inner shaft 720. Accordingly, the inner shaft 720 is formed as a cylindrical shaft having a hollow portion so that the other end of the outer shaft 710 can be inserted. Accordingly, one end of the outer shaft 710 is coupled with the other end of the length motor part 600, and the other end of the outer shaft 710 is partially inserted into the inner shaft 720.

In addition, as shown in FIG. 4, it is preferable that the outer surface of the other end of the outer shaft 710 and the inner surface of the inner shaft 720 are formed with threads. Therefore, when the outer shaft 710 is rotated by the length motor part 600 coupled to one end of the outer shaft 710, the thread formed on the other end of the outer shaft 710 is It can be rotated along the thread formed on the side.

In this case, it is preferable that the outer shaft 710 and the inner shaft 720 are coupled to each other by a type of bearing, which is a mechanical element that is rotatably supported while supporting a load acting on the shaft or the housing. Therefore, when the outer shaft 710 rotates along the length motor part 600, the rotational motion can be changed into a linear motion between the outer shaft 710 and the inner shaft 720 due to bearing coupling.

Due to the above structure, the first roller 410 and the second roller 420 coupled at the other end of the support shaft 730, respectively, can move reciprocally in the longitudinal direction.

This means that the first roller 410 and the second roller 420 reciprocate in the longitudinal direction at the same time as they rotate, rather than being fixed and rotated at only one position. Since the area in which the roller 420 can contact is increased, the effect of removing foreign substances can be further maximized.

In addition, due to the mutually threaded structure of the outer shaft 710 and the inner shaft 720, there is an advantage in that the life of the device is increased because the frictional force is reduced and the movement is smooth.

In addition, according to the present invention, the other end of the support shaft 730 is divided into two ends so that the first roller 410 and the second roller 420 can be rotated independently. Here, the coupling of the other end of the support shaft 730 with the first roller 410 and the second roller 420 is a known bearing coupling, and even if one side with the support shaft 730 is coupled, the first roller 410 and The second roller 420 may be rotatable. This is a known technique and a detailed description thereof will be omitted.

As shown in FIG. 4, the other end of the support shaft 730 is preferably formed by being divided into a first roller shaft 731 and a second roller shaft 732 so as to have two axes in the longitudinal direction.

Accordingly, the first roller shaft 731 is inserted into the first roller 410, and the second roller shaft 732 is inserted into the second roller 420 to be coupled.

As above, the first roller 410 and the second roller 420 are inserted into the first roller shaft 731 and the second roller shaft 732, respectively, so that the first rotation motor 510 and the second rotation motor 520 ), the first roller 410 and the second roller 420 are rotated respectively, so that they can be independently driven as needed, thereby increasing work efficiency.

The spring unit 900 is provided in plural, and is preferably coupled to the other side of the first rotation motor 510 and the second rotation motor 520 and one side of the length motor unit 600.

The spring unit 900 is one of mechanical elements that absorbs and accumulates energy using the elastic deformation of an object to act as a buffer, etc., and the first roller 410 and the second roller 420 are connected to the rope ( In addition to inducing contact with the surface of 10), there is an effect of mitigating the impact generated while the first rotation motor 510 to the length motor part 600 is driven.

Hereinafter, the case unit 1000 will be described with reference to FIG. 8.

The case part 1000 has a hollow part in the shape of a box having a rectangular parallelepiped, and the parts may be inserted and driven therein.

In this case, the case unit 1000 is divided into upper and lower portions, as shown in FIG. 9, and is provided as an upper case 1100 and a lower case 1200.

That is, the upper case 1100 is provided in a box shape with a hollow portion inside and a bottom opening, and the lower case 1200 is provided in a box shape with a hollow portion inside and an upper opening, The upper portions of the lower case 1200 may meet to form a complete box shape.

Accordingly, it is essential to replace the components inserted and driven in the case unit 1000 with parts having a certain lifespan. As the components can be separated into the upper case 1100 and the lower case 1200, the replacement is easy. There is one effect.

In addition, since it is a device for removing sludge for elevator ropes, it is required to continuously collect sludge such as dust and dust, and thus, cleaning work is required according to a certain period. Accordingly, since the periodic cleaning operation is facilitated by free separation and combination of the upper case 1100 and the lower case 1200 of the present invention, there is an advantage in that management efficiency is increased and the life of the device is increased.

In addition, the upper surface of the upper case 1100 and the lower surface of the lower case 1200 are provided with an upper groove 1110 and a lower groove 1210 cut into a rectangle. Accordingly, the rope 10 extending in the vertical direction passes through the upper groove 1110 and the lower groove 1210 to perform a sludge removal operation.

In addition, as shown in Figure 9, the lower surface of the lower case 1200 can be directly attached to and detached from the anchor made of metal surrounding the rope 10 by coupling a ferromagnetic material (F), thus overcoming the problem that was difficult to install on a conventional wall surface, etc. There is an effect that can be. Here, although not shown in the drawings, the anchor is formed by wrapping a plurality of ropes 10 spaced apart, and is a known technical configuration in which a plurality of anchors are formed by being spaced apart from the path in which the elevator moves.

In addition, since all the parts described inside the case unit 1000 are inserted, there is an advantage in that transportation is simple and work preparation time is omitted, thereby increasing work efficiency.

According to the present invention, the case unit 1000 has a feature of having a plurality of plates 1300 therein.

Reference will be made to FIGS. 10 and 11 to describe the plate 1300.

The plurality of plates 1300 have the same shape and are provided with a support part 1310, a coupling part 1320, and a side part 1330.

The support part 1310 is provided in a panel shape, and the coupling part 1320 is formed to extend in a vertical direction from one side of the support part 1310. The side portions 1330 are formed to extend perpendicular to both the support portion 1310 and the coupling portion 1320 in a pair.

Referring to FIG. 11, the plate 1300 having the above shape is symmetrical with respect to the first roller 410 and the second roller 420 to form a pair, and the first roller 410 and the second roller ( Sludge removed from 420) can be collected.

In addition, the pair of plates 1300 is formed in a parallel structure based on the first roller 410 and the second roller 420, and the rope 10 is formed by the first roller 410 and the second roller 420. It is possible to maximize the collection of sludge removed from the surface of the surface.

At this time, it is preferable that the plurality of support portions 1310 are coupled to have a predetermined angle α from the parallel line A. Here, the parallel line A means a line parallel to the upper case 1100 or the lower case 1200 (see FIG. 10 ).

Therefore, since the support part 1310 has a certain inclination, the sludge removed from the first roller 410 and the second roller 420 is collected in one place along the slope of the support part 1310 to increase collection efficiency. It has the advantage of being.

If the slope is not formed on the support part 1310 and is parallel to the upper case 1100 and the lower case 1200, the sludge removed from the first roller 410 and the second roller 420 is the first roller. In the vicinity of the 410 and the second roller 420, the first roller 410 and the second roller 420 may be adhered to the first roller 410 and the second roller 420 again, and the sludge removal efficiency may decrease by falling into the lower groove 1210.

Accordingly, in the present invention, it is possible to increase collection efficiency by providing the support portion 1310 having an inclination so that sludges can be collected from the support portion 1310 toward the coupling portion 1320.
