Definitions
- the present invention relates to an elevator guide rail that guides up and down movement of a car or counterweight in a hoistway.
- a car and a counterweight suspended in a hoistway via a main rope are lifted and lowered in a slidable manner.
- the car, the balance, and the weight are guided by the guide rail.
- the guide rails are laid on the inner wall of the hoistway at predetermined intervals through the rail support member throughout the hoisting process.
- Conventional guide rails are formed in a generally T shape with the rail portion standing upright on a plate-like base, and the T shape rail shown in ISO or EAS standards is used, and the base is used as a rail support member. It is designed to guide the car and counterweight on the rail. (For example, see Patent Document 1)
- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-238045 (Pages 3, 4 and 1 and 2)
- the guide rail guides the car and the counterweight. Force is received from the car or the counterweight by an earthquake or emergency stop. Therefore, strength against this load is required.
- the guide rails are laid throughout the lifting / lowering stroke, the higher the lifting / lowering stroke, the more guide rails are required per elevator, and the larger the car capacity, the larger the guide rail size. . For this reason, elevators are required to have a guide rail with a lower material requirement while ensuring a desired strength, that is, a smaller material requirement relative to the strength.
- the present invention was made in order to solve the problem of power, and to obtain a guide rail having a small material requirement relative to the strength while reducing the material requirement while ensuring a desired strength. With the goal.
- the elevator guide rail there is a car that is formed in a substantially T shape in which the rail portion is erected on a plate-like base portion, and the guide body is engaged with the rail portion! / It guides the lifting and lowering movement of the counterweight and forms a dent in the center of the bottom of the base.
- an elevator guide rail having an increased strength while suppressing a required amount of material can be obtained by allocating a recessed portion at the center of the bottom surface of the base to the both ends of the base and the top of the rail.
- FIG. 1 is a cross-sectional view of a guide rail according to Embodiment 1 of the present invention.
- FIG. 2 is a diagram showing an example in which the guide rail in Embodiment 1 is applied to an elevator.
- FIG. 3 is a diagram showing a comparison between the guide rail of Embodiment 1 and a conventional guide rail.
- FIG. 4 is a diagram showing a usage state of the guide rail according to the first embodiment.
- FIG. 5 is a view showing a guide rail in another embodiment of the present invention.
- FIGS. 1 to 3 are views showing Embodiment 1 of the present invention
- FIG. 1 is a sectional view of the guide rail of this embodiment
- FIG. 2 shows an example in which the guide rail is applied to an elevator
- 3 is a comparative view of the guide rail of the present embodiment and a conventional guide rail
- FIG. 4 is a view showing a use state of the guide rail of the present embodiment.
- a guide rail 1 has a plate-like base portion 2 and a rail portion 3 formed in an upright state and has a substantially T shape.
- the upper surface of the base portion 2 is formed with an inclined surface 2a, and the bottom surface is formed with a circular recess 2b at the center portion.
- the guide rail 1 is laid on the hoistway by fixing the flat part of the bottom to a rail bracket (not shown) and fixing the rail bracket to the inner wall of the hoistway at a predetermined interval.
- the rail portion 3 has a rail head portion 3a that engages with a guide body (not shown), and the rail head portion 3a is connected to the base portion via a rail neck portion 3b that is narrower than the width. These are integrally formed to constitute the guide rail 1.
- Figure 2 shows an example in which the guide rail 1 is applied to an elevator.
- (A) is a top view and (b) is a front view.
- a guide body 5 is provided at the four corners of the car 4, and the guide body 5 is engaged with the guide rail 1 to guide the car 4 to the guide rail 1 and move up and down. Further, the guide rail 1 is fixed to the inner wall of the hoistway through the rail bracket 6 at a predetermined interval.
- Figure 3 shows a comparison with a conventional ISO T-rail as an example.
- the guide rail 1 of the present embodiment has a dent 2b formed at the center of the bottom surface of the base 2 and a center of the bottom surface of the base 2 so that the centroid A of the cross section is substantially at the same position as the conventional ISOT rail.
- the recess is formed by allocating to both end faces of the base 2 and the top of the rail head 3a.
- the height HI of the end face of the base 2 and the inclination angle of the inclined face 2a of the base 2 are the same as those of the ISO T-shaped rail.
- Both the width B of the rail head 3a and the height H2 of the rail head 3a It is formed to be the same as the ISO T-shaped rail.
- the guide rail 1 of the present embodiment has the same cross-sectional area as that of the conventional ISO T-shaped rail, but has a recess 2b formed in the center of the base 2 and is close to the centroid A of the cross-section.
- the secondary moment can be increased and the section modulus can be increased. Also grows. This allows the same material requirements as conventional ISO T-rails in two directions (Fig. 3). The strength against bending moments in the horizontal direction and the vertical direction can be increased.
- FIG. 4 shows an example of its use.
- the rail clip 7 is fixed to the rail bracket 10 by pressing the inclined surface 2a of the base 2 with bolts 8 and nuts 9, and the guide rail 1 is fixed to the rail bracket 10.
- the guide roller 11 which is a guide body is engaged with both side surfaces and end portions of the rail head portion 3a, and guides an elevator (not shown) provided with the guide body or an up-and-down movement of a counterweight.
- the guide rail 1 includes the conventional ISO T, the height of the end surface of the base 2, the inclination angle of the base 2 inclined surface 2a, the width of the rail head 3a, and the height of the rail head 3a. Since it is the same as the shaped rail, the rail clip 7 that fixes the guide rail 1 and the guide roller 10 that is a guide body can use conventional existing parts. Therefore, it is economical that the guide rail 1 with a small material requirement and high strength without using new parts can be applied to the elevator.
- the circular recess 2b is formed at the center of the base 2, but the present invention is not limited to this.
- a square recess 2c may be formed in the center of the base 2.
- the elevator guide rail 1 that is useful for the present invention is a car in the hoistway! / ⁇ is balanced! / Used for equipment that guides the elevating movement of the weight Suitable!
