Description

  The present invention relates to a wire rope lubricant applicator for the purpose of lubrication and rust prevention, and in particular, the lubricant is applied to the surface of the wire rope thinly and uniformly coated regardless of the type of lubricant. The present invention relates to a lubricant applicator for wire rope.

  Conventionally, wire ropes have been widely used for driving cranes, elevators, lifts, dams, river gates, etc., and these wire ropes are regularly supplied with a lubricant to prevent corrosion and wear. Has been done.

  The most common method of applying a lubricant to a crane wire rope is hand coating. When supplying fluid lubricating oil with fluidity, there are some cases where equipment that can automatically lubricate is used, but when supplying semisolid grease that does not have fluidity. The mainstream is still hand-painted.

  By the way, in the liquid lubricating oil having fluidity and high permeability, the applied lubricating oil penetrates to the fiber core of the wire rope and does not stay on the surface.

  However, in the case of grease with low fluidity and low permeability, the applied grease stays on the surface of the wire rope as it is, and sometimes drops until it spreads evenly on the surface of the wire rope, There is a problem of polluting the surrounding environment such as rivers.

  In recent years, for the purpose of downsizing a crane, there is a tendency to make a winch drum smaller and lighter by making a wire rope, which is a single layer winding of a conventional winch drum, into a multi-layer winding. Along with this, the friction between the wire ropes has increased and the frequency of oil supply has increased, and in particular, the need for automation of grease application has increased.

  Conventionally, a technique shown in FIG. 9 is known as this type of wire rope lubricant application device (see, for example, Patent Document 1). In the lubricant application device shown in the figure, a wire rope 61 is sandwiched in a cylindrical container 60 composed of halved parts 60a and 60b, and grease is supplied by a grease pump until the grease supply chamber 62 in the cylindrical container 60 is full. Is forcibly injected at high pressure.

  Upper and lower sealing materials 63a and 63b and lower sealing materials 64a and 64b, which are combined to form a ring shape, are respectively disposed on the upper and lower sides of the grease supply chamber 62, and the injected grease leaks from the cylindrical container 60. It is not going out.

  According to this lubricant application device, since grease is supplied to the wire rope at a high pressure, it can be lubricated from the surface to the inside.

  In such an application operation, it is ideal that the grease or the like is applied in a thin and uniform state on the surface of the wire rope.

  However, with the sealing materials and brushes provided in conventional lubricant application devices, it is difficult to apply grease uniformly between the strands constituting the wire rope, and extra grease is applied. As a result, grease etc. can be easily peeled off and not only interferes with lubrication and rust prevention, but also adversely affects the environment, and it is difficult to repaint the next time due to hardening due to deterioration of the grease etc. There was a problem.

  Therefore, the problem to be solved by the present invention is to provide a wire rope lubricant applicator capable of applying a lubricant in a state where the surface of the wire rope is thinly and uniformly coated.

  The present invention has been made in order to solve the above-mentioned problems, and the invention according to claim 1 is characterized in that a strand in which strands are combined in a single layer or multiple layers is formed at a predetermined pitch around a fiber core or a steel core.

Since the shape of the trajectory is drawn, when the wire rope moves relatively downward, the first rotor tends to move upward along with it, but the wall surface of the first rotor chamber Therefore, it cannot move any further downward and rotates in the circumferential direction. The lubricant injected in the lubricant injection chamber is spread in the circumferential direction by spreading in the gap between the first rotor and the wire rope as the first rotor rotates. Since the first rotor moves relative to the upper direction of the wire rope, the first rotor spreads in the upper direction of the wire rope.

  Therefore, according to the first aspect of the present invention, the lubricant can be applied with a constant thickness on all portions of the surface of the wire rope that has passed through the first rotor, and the first rotor and It is possible to apply thinly by reducing the gap with the wire rope.

Of rope The rotated around axis, through close contact portion between the wire rope and the groove, is characterized in that extending painted lubricant injected into the wire rope uniformly downward direction and the circumferential direction of the wire rope.

  According to the second aspect of the present invention, in addition to the effect of the first aspect, the second rotor chamber having the same function as the lower side and the second rotor are configured on the upper side of the lubricant injection chamber. Therefore, even if the wire rope moves relatively upward, the lubricant is applied with a constant thickness on all the portions of the surface of the wire rope that has passed through the second rotor, It is possible to apply thinly by reducing the gap between the rotor 2 and the wire rope.

  According to the invention of claim 2, the lubricant application device can be externally fitted to the wire rope by combining the device main body, the first rotor, and the second rotor, Although it can be mounted in a different direction, it can be applied in any direction, so it is not necessary to remove the lubricant application device and install it in a different direction, saving labor. be able to.
