DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a door opening/closing drive device for opening and closing doors of elevator seats and halls.

[Technical background of the invention and its problems]

Figure 1 shows the entire conventional passenger car, with a vertical frame 2a connecting an upper frame 2c1 and a lower frame 2d extending approximately at the center of the car 1.
, left and right support arms 3 provided to protrude forward from 2b.
A mounting base 4 is attached to the front part of a13b, a mounting plate 5 is fixed to the mounting base 4, and a control device 6as') is attached with a mounting seat 7.

A TM, a motive force 8 and a speed reducer 9 are attached to the mounting plate 5, and the control device 6a is equipped with a pulley 11 having the same rotating shaft 10.
A is attached. The link 12 is rotatably attached to the mounting seat 7 at one end and the link 13 at the other end,
One end of the link 12VC is rotatably attached to the door 14, and the link 15 has one end attached to the reduction gear [
The other end is pin-linked to Ua through link 12.

However, in the installation and adjustment of each of the above-mentioned devices,
Motive 8 and Boo! J-9Vi front and back position adjustment is impossible on the mounting plate 5”! The position is determined at the stage of warping, so the control l11j device 6B is adjusted in the longitudinal direction to determine the adjustment position f6, and the link is attached to the pulley +ia determined by the control device 6a and the slot 15. It is very difficult to assemble and adjust many parts etc. in a narrow space at the installation site, which is very difficult to determine the adjustment position of the seat 7 in the front-back direction, and then adjust the mounting base 4 in the front-back direction and attach the J3 to the door 14. There was a problem.

Mapco, not only does it take more time and effort to perfectly adjust the position of each of the above devices, but in terms of performance, if the installation adjustment is insufficient, there will be a loss of force until the rotational force of the electric WIJI machine 8 drives the door 14. As the operation N increases, the electric motor becomes overloaded, and the transmission of force becomes less smooth, which may adversely affect the opening/closing performance.

The number of people who install it on the mounting base 4 as shown in Figure 2 is 4.

The shape of the upper part of the board is uneven, making it difficult for workers to secure a foothold when riding from the landing to the top of the corner during maintenance and inspection. In addition, when opening and closing the door during work after transfer, the electric motor 8, pulley 9, lla,
Because there are rotating parts such as links 12 and 15, there was a risk of accidental contact with the equipment and injury.

In addition to the above, the production, packaging, transportation, and loading of each device are handled on a component-by-part basis, resulting in a lot of effort and effort, such as confirmation work.

[Purpose of the invention]

The present invention seeks to provide a device to overcome the above-mentioned drawbacks.

72. [Overview of the invention] The various devices of the opening/closing drive device, electric motor, deceleration device, control device, link fulcrum, etc. of the present invention are housed in a box-shaped frame that also serves as a stand (partially exposed). ), and provides an integrated door opening/closing drive device that compactly accommodates each of the above devices and secures a space for maintenance and inspection above the car.

[Embodiments of the invention]

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

Support arms 3a, 3b extending forward and horizontally from the vertical frame of the car frame that supports the passenger, the above-mentioned support arms 3 in FIG.
A13B A box-shaped support member W1 made of steel or non-ferrous metal passed between a13b and a wedge-shaped member extending from the front and bottom of this support member W1 to the upper surface member 2 that covers ia and the upper part
A co-moveable member such as a hinge is provided on the upper part of the portion 16a on the front side. - Attach a stopper to the top surface material 21 to lift the rear part of the top surface material 21 and regulate the opening/closing angle with the front Nfi rotating member addition part, and also install a stopper on the top surface material 21 to fix it when the top surface material 21 is closed. A locking hole is provided in the image value part of the frame, and the eye bolt (hanging part side) 22 is screwed into the hole through the hole.

On the other hand, on both sides of the support member 16 there are closing portions ifA19a.
11gb is provided, which is fixed to the member 16a by screws or welding, etc., and serves as a support when the end-reinforcing upper upper surface material 21 is attached when closed, and when a maintenance worker stands on the upper surface material 21. It is.

By the way, the door opening/closing drive device is attached by removing the inside and part of the support member 16.

First, put the motor body into the support member 16, and fix a part of it with a screw member with the output shaft peeking forward from the back side of the member 16a. A pulley is attached to the end of the output shaft, and a rotatably supported pulley 9 is provided on the left side 1111 of the pulley.

The dynamic force is transmitted by a wrapped belt or chain 7. The pulley 9at is still mounted concentrically and integrally with the pulley 9. A pulley 11 b and a pulley 11 b are directly connected to the control device 6 blc housed in the support member 16 and are pivoted to the surface of the control device 6 blc.
From b, the link mounting seat 17 for configuring the opening/closing operation by the link mechanism using the link 12.15 is attached to the front surface of the support member 16 with a screw member or the like.

As shown in Fig. 4, the front part of the unit side 6 is formed in a straight line, and since a wheel or a deceleration device is fixed to the front and rear parts, they are necessarily arranged on the same plane. will be established.

As shown in FIG. 5, like the L-shaped member 16a, the structure of the L-shaped top member 21 makes the entire support member W box-shaped, and the overall section modulus increases, making it a relatively thin member in terms of ΦQ. Can be configured.

Since there is only the protruding portion of the eye bolt 22 (end) on the 10-sided portion of the top surface material 21, it is not only possible to get in easily when performing maintenance and inspection on the upper part of the car, but also improves work safety.

ej! As shown in Fig. 6, the top member 21 can be opened to a dimension S by a rotary member provided at the front for the purpose of easily inspecting the inside of the door opening/closing drive device, and its limiting stopper n can be opened from the front at a certain angle. It is provided so that it slightly protrudes from the part, and it hits the old 168 surface of the part and controls its rotation from 1 to 11 city 1.
7. Define the opening and closing angles 1 and 11. Furthermore, it goes without saying that there is no need to provide a restricting stopper.

However, the devices and equipment that are stored and attached to the support member that is the door opening/closing drive device are units that have been assembled in advance at a factory, etc., and are attached to both ends as shown in Figure 7. A device is provided by fitting the top member 21 together.

However, the eye bolts 22 and the like do not necessarily need to be aligned with the top member 21, and may be attached separately.

The support member 16a'd may be L-shaped, but the support member 16a'd may be box-shaped together with the side plates 19a and 19b.

According to the above configuration, the electric ji118, the pulley 9.
The reduction gear such as 11b and the link mounting seat 17 are connected to the member 168. Since they are fixed on the same plane on the front surface of the machine, if the parts of each device or device are made accurately, the relative dimensions between them will inevitably be secured, so it is possible to adjust several features like in the past. No work is required.

On the other hand, the work of assembling the opening/closing sliding device into the support member 16 can be done in a factory. As a result, the work of packing, transporting, carrying in, and on-site assembly and adjustment of the convex sides does not have to be done in the elevator hoistway, where conditions are poor, and the entire unitized door opening/closing drive device only needs to be done once, making the work easy. It can be accomplished in a short period of time.

Of course, the on-site work is carried out by hoisting both ends using eye bolts using a blockchain or crane as shown in Figure 7.

The end of the top material 21 on the opposite side from where it is fixed with the hinge is bent four times to improve its strength, so that the work I can be carried out on top of the top material 21 during maintenance and inspection. In addition to securing a wide foothold, [i? J1
Machine 8, pulley 9.11b1, and link 12.15 are located further below the scaffolding, and 7 barrier 1 device 6b is stored under the top panel material 21, so there is no need to make any adjustments to each device that rotates when opening and closing the door. Work can be carried out safely as there is no danger of direct contact with plastic members.

Also, when inspecting the control device 6b and the contacts of the electric motor 8 inside the member 16, top surface material 21, and side surface material 19a119b, remove the hanging bolts 22 [7]: Stop the surface material 21 upward with the stop metal fitting n. Since it can be opened up to the point P, it is easy to open the point +I? l can be done. Note that the position S where the top member 21 stops at the stop fitting z3 is not illuminated in the figure, but it is better not to project forward beyond the car sill. Even if you mistakenly operate the car for inspection with the top panel 21 open, if the car does not protrude beyond the car sill, which is the most forward-protruding part of the car, the equipment on the landing side or in the hoistway will protrude. This is to prevent the risk of interference with objects.

〔Effect of the invention〕

According to the present invention, the elevator door opening/closing drive device is assembled in a factory and shipped as a unit with accurate quality assurance, and the device is a high-efficiency, low-cost product with high quality and good workability in an environment. is ensured.

In particular, the installation adjustment work at the installation site can be carried out safely by carrying in the unitized door opening/closing drive device (supporting member) and by the LE company.

By forming the support member into a box shape by unitizing the above, it is possible to provide a door opening/closing drive device that is good in terms of ensuring the installation accuracy of the equipment and equipment that are fixed on the same plane. It is something.
