Abstract

(57) [Abstract] [Purpose] Eliminates the work of scraping the steps created on the elevator guide rails with a file, etc., and can significantly reduce the labor. [Structure] All traveling surfaces 4a from an upper end portion A to a lower end portion B of an elevator guide rail 4 vertically installed in the hoistway 1 for guiding a car and a counterweight moving up and down in the hoistway 1 The guide member 7 integrally covers the traveling surface 4a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator guide rail.

[0002]

[Prior Art]

 In general, the guide rails for elevators were unit guide rails with a length of about 5 m that were connected throughout the entire elevator, and were fixed to the hoistway walls via brackets at intervals of about 3 m.

A device related to the present invention is, for example, Japanese Patent Laid-Open No. 61-7184.

[0004]

[Problems to be solved by the device]

 In the above, the required number of elevator guide rails are connected to the hoistway stroke by bolts, etc. in the hoistway, and brackets are installed on the hoistway wall so that the elevator running surface becomes straight in the running direction. It was fixed. However, the connecting part of the guide rail is likely to have a step due to the deviation of the manufacturing accuracy and the assembly accuracy, and it was necessary to grind it with a file etc. so that it would be smooth with a great deal of effort.

The present invention is intended to solve the above problems, and an object thereof is to provide an elevator guide rail that can eliminate the work of fitting the guide rail connecting portion.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a guide rail of an elevator vertically installed in a hoistway for guiding a car and a counterweight moving up and down in the hoistway. A guide member that integrally covers the traveling surface is provided on the entire traveling surface from the upper end portion to the lower end portion.

[0007]

[Action]

 Since the guide rail of the elevator according to the present invention is configured as described above, the guide member integrally covers the entire traveling surface from the upper end to the lower end of the guide rail standing in the hoistway. Therefore, it is possible to smooth the step formed in the guide rail connecting portion without sanding or the like, so that the labor can be greatly reduced.

[0008]

【Example】

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

FIG. 1 is a side view showing a usage state of an elevator guide rail according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG.

In FIG. 1, reference numeral 1 denotes a hoistway, and a guide rail 4 is erected on a hoistway wall 2 of the hoistway 1 via a bracket 3. The guide rail 4 guides a car (not shown) that moves up and down and a counterweight (not shown), and is usually connected with a unit having a length of 5 m. Reference numeral 5 is a connecting plate that supports the connecting portion of the unit guide rail 4, and 6 is a machine room. Reference numeral 7 is a guide member that integrally covers the entire running surface from the upper end A to the lower end B of the guide rail 4. In addition, 8 shown in FIG. 2 is a catch of a safety device provided at the bottom of the car.

In order to mount the guide rails 4 on the hoistway 2, however, the guide rails 4 each having a unit of 5 m are connected to each other to form one long guide rail 4 via the bracket 3. The guide rails 4 are attached to the wall 2 or the guide rails 4 are individually attached to the hoistway wall 2 via the brackets 3. Next, the guide member 7 is attached so as to cover the entire traveling surface 4a of the guide rail 4.

With the above-described configuration, it is possible to eliminate the step generated in the connecting portion of the guide rail 4 without performing the attaching operation of the connecting portion of the guide rail 4, and to reduce the great working time required for the attaching operation as much as possible. it can.

Although the length of the guide rail 4 is conventionally set to be 5 m, this length may require a great deal of effort to carry it into the hoistway 1 from a narrow doorway. On the other hand, in the case of the present invention, since the rubbing work is eliminated, the guide rail 4 can be a short length of 3 m unit or less, and can be carried in very easily.

Further, the car guide roller shoes (not shown) are less worn, and when the guide rail 4 is bent in a dogleg shape to stand upright, the guide member 7 is hung down. When attached, this bending condition can be easily determined.

It should be noted that by setting the holding portion by the catch 8 at a place other than the guide member 7, it is possible to prevent the guide member 7 from being damaged when the catch 8 operates.

[Effect of the device]

 According to the present invention, it is possible to omit the work of scraping the step generated at the guide rail connecting portion with a file or the like, and it is possible to significantly reduce the labor.
