DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing rust-preventive oil on a guide rail used for, for example, guiding elevator cars to lift and lower a counterweight.

[0002]

2. Description of the Related Art In an elevator which is currently in general use, in order to raise and lower a car and a counterweight in a hoistway, a large number of right and left guide rails are vertically connected to the inner wall of the hoistway. The guide rollers are slid against the rail portions of the left and right guide rails so as to guide the car and the counterweight so as to be able to move up and down.

[0003] Since the guide rail is made of a steel material and is surface-cut, the guide rail may be left for a long time after the processing,
If people touch it during the installation work, the surface will rust,
A smooth guide function as a guide rail cannot be sufficiently exhibited. For this reason, normally, in order to prevent rusting of the guide rail, a high-viscosity rust-preventive oil is applied thickly over the entire rail portion after processing.

[0004] However, the guide rail coated with rust-preventive oil does not rust, but if it is installed and used in a hoistway with the rust-preventive oil applied, the rust-preventive oil on the rail portion is reduced. The guide rollers of the car and the counterweight are in direct contact with both sides and the top surface marked with, and the resin portion of the guide rollers is damaged by erosion with rust-preventive oil. Dust easily adheres to the rail surface, hinders the operation of the guide rollers, and deteriorates the ride comfort of the elevator.

[0005] Therefore, this type of guide rail is used before installing a car or a counterweight, such as during construction on site.
It is necessary to remove the rust-preventive oil that has been applied thickly on the rail surface, and the removal of the rust-preventive oil has conventionally been done manually by a worker using a cloth containing a solution of rust-preventive oil such as gasoline. I was wiping it off.

[0006]

However, such a work of removing the rust-preventive oil from the guide rail by hand wiping requires that a cloth be applied to the surface of the rail portion and strongly rubbed over the entire surface.
It was a lot of hard work for the workers,
There was a problem that rust-preventive oil was left behind. In addition, since the rust preventive oil solution (gasoline, etc.) contained in the cloth is often a flammable substance, there is a danger of fire during work and strict attention must be paid to handling firearms around. Met.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to remove a rust-preventive oil from a guide rail very easily and reliably, to save labor, and to solve a dangerous solution such as ignition. It is an object of the present invention to provide an apparatus for removing rust-preventive oil from a guide rail, which does not require the use of a guide rail and improves safety.

[0008]

According to the present invention, there is provided an apparatus for removing rust-preventive oil from a guide rail, the apparatus comprising: a main body movable along the guide rail in the longitudinal direction of the rail; Guide means for keeping the attitude of the apparatus main body substantially constant with respect to the rail portion of the attached guide rail;
A rust-preventive oil removing member having a hardness lower than that of each of the rail portions, which is slidably attached to the top surface and both side surfaces of the rail portions of the guide rails at the edge portions over the entire width, respectively; A biasing means is provided for pressing the rust-preventive oil removing members on both sides in sliding contact with the side surface against the rail portion side surface.

With such a rust-preventive oil removing device for a guide rail, the device main body is simply set on the guide rail and moved in the longitudinal direction of the rail. While keeping the distance substantially constant, the rust-preventive oil removing members on the upper and both sides mounted on the apparatus main body are in sliding contact with the top surface and both side surfaces of the guide rail over the entire width so as to sandwich the rail portion.
At this time, the rust-preventive oil removing members concentrate the pressing force on the respective edge portions and slide in contact with the rail portions so as to rub against the rail portions.
Since the hardness is lower than that of the rail portion surface, it comes into close contact with fine irregularities on the rail portion surface.

This makes it possible to reliably remove the rust preventive oil on the top surface and both side surfaces of the rail portion of the guide rail so as to kill off without leaving any residue, thereby saving labor and reducing the risk of fire. It is not necessary to use a dissolving solution, and safety can be improved. Moreover, since each rust-preventing oil removing member has a lower hardness than the rail surface, there is no need to worry about damage such as abrasion on the rail surface.

In the rust-proof oil removing device for the guide rail, at least one of the rust-proof oil removing members on both sides is movable against the urging means to open and close the rust-proof oil removing members on both sides. By providing the mechanism, the device can be easily set on the rail portion of the guide rail in a state where the mutual distance between the rust-preventive oil removing members on both sides is increased by operating the opening / closing mechanism, and the workability is further improved.

Further, in the rust-preventive oil removing device for a guide rail, the rust-preventive oil removing members on both sides are each formed in a horizontally long plate shape from a material having a lower hardness than the rail portion surface of the guide rail, and each lower side is provided with a lower plate. edge portion that assembled to each apparatus body sliding contact state over the entire width in the downward direction of travel behind relative to the rail part side surfaces of the guide rail tilting.

With this arrangement, when the apparatus main body is moved along the rail portion of the guide rail, the lower edges of the rust-preventive oil removing members in the shape of the elongated plates on both sides are rearward in the traveling direction with respect to both side surfaces of the rail portion. Since the rubbing oil is slid over the entire width by the downward slope, the rust-preventive oil that has been killed from both sides of the rail at this edge is gradually pushed down along the edge without stagnating in the middle and is eliminated without being left behind. As a result, the rust-preventive oil can be continuously removed from the long guide rail.

[0014]
