Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hoistway detector device installed on an elevator hoistway and operated by a car.

[Technical background]

In addition to the normal deceleration and stop, the elevator hoistway is equipped with a system that detects the push-up and push-down of the car at a portion slightly beyond the final floor above and below the hoistway to prevent the car from rising or falling any further than necessary. A safety switch is installed at the last floor that sends a signal to the elevator control device to command deceleration and make an emergency stop.

As an example of this, as shown in FIG. 1, a plurality of limit switch groups 1 are mounted on a car 2 at the end of a hoistway, and an operating cam 3 drives an operating lever 1a of a limit switch 1. And basket 2
This is a means for detecting that the vehicle is in the deceleration zone of the terminal floor and detecting whether the normal deceleration device is working normally. If this is abnormal, the car 2 will be pushed up, and a safety device is provided to issue commands such as forced deceleration and stop to prevent an accident.

The conventional method of mounting the limit switch group 1 is as shown in FIGS. 2a and 2b. That is,
A support member 9 is attached to a rail 8 provided vertically in the hoistway for guiding the car using two fasteners 10 and bolts 1.
1, and a limit switch 12 is mounted on the supporting member 9 with bolts 13 on the back side. These position adjustment operations involve attaching and detaching the bolts 11 and 13. In particular, all rollers 14 must be aligned in a given dimension and in a colinear manner. Furthermore, the mounting intervals A and B of the upper and lower limit switches are very important dimensions for controlling the deceleration distance and other factors for emergency stops and emergency stops, and accurate adjustment and mounting is required.

If the mounting position of the support member 9 matches the joint of the rail 8, it is necessary to provide another mounting member (not shown).

In addition, the above work involved working at heights with poor footing in the hoistway, and the work process was complicated, requiring not only experience and skill, but also time and safety problems.

[Purpose of invention]

The present invention was developed based on the conventional technical background, and aims to improve the installation adjustment work and ensure accurate installation of a device for detecting thrust up and thrust down provided at the final end of a hoistway.

[Summary of the idea]

The present invention consists of a vertical groove provided on the outer surface of the detector, and a vertical mounting mounted on the hoistway that engages with the groove. A horizontal groove provided on the outer surface of the detector, and a horizontal mounting member that engages with the groove provided on the hoistway. (Installation) This facilitates adjustment work.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, a support member 9 attached to the main rail is also provided in the lower part (not shown) in the same way as in the conventional case, and a mounting member 15 is attached to the top end of the support member 9 in the upper and lower directions, and a screw 1 is provided.
Attach at step 6.

This is a detector that engages with the protrusion 15a of the U-shaped mounting member 15. (hereinafter referred to as limit switch) A recessed groove 1 is formed on the back side of the limit switch 17.
7a is provided vertically and a mounting seat 17 is provided in the middle part thereof, and a female screw 17c is bored therein to connect the protrusion 15a of the mounting member 15 and the groove 17a of the recess.
Attach from the back using the set screws 18. The limit switches 17 are mounted at dimensional intervals A and B in the same manner as in the prior art, and constitute a hoistway detector device.

The mounting member 15 has a long hole 1 through which the screw 18 passes through.
A large number of holes 5b are continuously drilled along the longitudinal direction.

According to the above configuration, when the limit switch 17 is mounted on the hoistway, the supporting member 9 is simply fixed to the two main rails in the upper and lower directions, and another mounting member 15 is vertically installed between them to adjust the vertical distance. By simply ensuring that the A and B dimensions are the predetermined dimensions, and by fitting the groove 17a of the limit switch 17 into the protrusion 15a of the mounting member 15, the upper and lower rollers 14 will be aligned approximately in a straight line, and the desired dimensions can be achieved by natural mounting and assembly. can be secured.

Further, even if the pitches A and B between the limit switches 17 are freely moved and changed using the protrusion 15a of the mounting member 15 and the groove 17a of the limit switch 17 as guides, the linear arrangement of the switch operating roller 14 remains unchanged, and Has a rotation prevention function.

Furthermore, the elongated hole 15b of the mounting member 15 and the single screw 18 make it easier to adjust the pitch of the limit switch 17 and to set it accurately.

Further, the mounting member 15 and the limit switch 17 can be assembled in advance in a factory with a good working environment, and then carried together into the hoistway and installed.

As a result of the above, according to the present invention, the number of man-hours required for adjusting the installation of the hoistway detection device to the hoistway can be reduced, accurate installation can be achieved, and detection accuracy can be further improved.

[Other embodiments of the invention]

As shown in FIG. 4, a horizontal groove 17d is provided on the back surface of the limit switch 17, which is a detector, and a horizontal mounting member 1 is provided with this groove in the hoistway.
It engages with the protrusion 15a of No. 9 and is attached using the elongated hole 15b and the screw 18 in the same manner as shown in FIG.

In the above two embodiments, the mounting members 15 and 19 have two distributed grooves 17a and 17d, but as shown in FIG.
In addition to being able to be installed vertically or horizontally,
In the above example, the mounting part is provided on the back, but it may be provided on the side, top and bottom, or the front and fixed to the mounting member.The mounting member is not limited to a U-shape, but may be square or L-shaped. It goes without saying that the same structure can be achieved using the same method, and the same effect can be obtained.

[Overall effect of the idea]

When installing a group of limit switches that are detectors as a hoistway detector device, the mounting member that serves as a guide rail for the limit switches installed along the elevator guide rail makes it easy to install them on the same straight line without having to adjust them. It is extremely labor-saving and can be installed accurately.

Moreover, it becomes easy to avoid overlapping in the positional relationship of the joints of the elevator guide rails, and the conventional problems can be solved.

Thus, according to the present invention, it is possible to pre-assemble the limit switches etc. in a factory with good workability, and by transporting them in one piece, it is possible to reduce the work at high places in the hoistway, improving safety and greatly reducing assembly work such as installation and adjustment work. It has the effect of improving.
