Description

Driving apparatus for opening and shutting door of elevator}

The present invention relates to an elevator door drive opening and closing device for carrying passengers or cargo in various buildings, and more particularly, to improve the power transmission unit and the door holding unit and the frame and tension control unit in the drive means of the elevator door. Through this, more reasonably, the door driving and opening and closing of the elevator can be made.

Mainly, elevator devices installed in high-rise buildings are used to load or unload people or cargo. In general, the elevator device is repeatedly lifted and lowered by the lifting and lowering device, a pair of doors are installed on the front of the elevator (car) to be made to open or close the door.

The door of the elevator is normally opened and closed by receiving power from a built-in drive motor, the drive motor is fixed to the frame mounted from the elevator, the door is a door holding part, etc. It is installed.

In addition, when looking at the driving means of the existing elevator doors, the rollers for the movement of the stirrer plate coupled to most doors are installed on only one side of the frame, so that the load on the rollers acts due to the weight of the door and the load during sliding operation. As a result, deformations and changes in tension of the rollers and the frame occur, which requires repeated and periodic maintenance and adjustment.

In particular, most elevator doors are provided with a door holding part for maintaining the door open state at the time of power failure regardless of whether the driving motor is operated. In order to maintain the open state of the door by the door holding part, The rollers to be mounted pass over the bent cams and the doors are squeaked due to mutual interference. Such interference forces not only cause the noise but also prevent natural sliding of the door. It is becoming.

In addition, in the case of a flat frame, excessive deformation is expected by mounting a door driving means, which is a heavy body, so that a metal plate made of an excessively thick material is used. Drive belts that enable the opening and closing of doors become loose as time passes. In this case, the maintenance costs are excessively expended due to the need to replace the drive belts or install additional tension rollers. To have.

The present invention improves the problems as described above, by placing the drive motor in the center of the door device to achieve an effective power transmission, and improves the door holding portion and a fluid roller mounted on the corresponding swasher plate to smooth the power failure The opening and operation of the door can be made, the structure of the frame on which the power transmission unit is mounted, the structural rigidity is increased, and the tension of the timing belt to provide the power of the drive motor delivered to the rinsing plate of the door is increased. Equipped with tension adjustment means that can be adjusted easily,

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall view of a drive device for an elevator door according to the present invention, FIG. 2 is a side view for a drive device for an elevator door according to the present invention, and FIG. 3 is a side view for a drive device for an elevator door according to the present invention. It is an enlarged view.

The drive opening and closing device of the elevator door according to the present invention as shown, the drive motor 10 is located in the middle of the frame 20 for installing the elevator drive opening and closing device; An interlocking wire (13) rotating together with the timing belt (12) and the timing belt (12) rotating with the power of the drive motor (10); A door (40) and (40 ') coupled to the hanger plate (30) (30') and the hanger plate (30) (30 ') coupled to the interlocking wire (13); The door holding body 50, 50 'coupled to the frame 20 is made of a configuration.

At this time, the drive motor (0) is located in the upper center of the frame 20 to prevent the bias of the weight applied to the frame 20 and at the same time the drive pulley (11) connected to the drive motor (10) ) Is to rotate in the forward and reverse directions.

In addition, when the drive pulley 11 coupled to the frame 20 rotates, the belt pulleys 16 and 16 'associated with the drive pulley 11 will rotate, so the belt pulley 16 spaced apart eventually. The rotation of the timing belt 12 connecting 16 'will occur.

In addition, the interlocking rollers 14 and 14 ′ spaced apart from each other under the timing belt 12 are connected by interlocking wires 13, and the upper and lower portions of the interlocking wires 13 are separate from each other. The rinsing plates 30 and 30 'are fixed.

At this time, one side of the rinsing plate 30 is connected to the upper portion of the interlocking wire 13 and at the same time coupled to the timing belt 12, the other side of the rinsing plate 30 'is connected to the lower portion of the interlocking wire 13 Therefore, when the timing belt 12 is rotated, the rinsing plates 30 and 30 'are spaced apart in opposite directions at the same time through the interlocking wire 13 in accordance with the rotation direction of the timing belt 12. It is a sliding operation in close proximity.

In particular, the interlocking rollers 14 and 14 'are inserted on a fixed shaft 19 for fixing and installing a separate rail 15 to the frame 20, and the fixed shaft 19 is Interlocking rollers 14 and 14 'inserted into the fixed shaft 19 positioned at both ends of the rail 15 as a large number are installed to withstand the weight of the rinsing plate 30 and 30' sufficiently. It is possible to maintain a relatively stable bonding state.

In other words, the conventional interlocking roller is fixed on a separate rotating shaft protruding from the fixed plate, and when a load is applied to the interlocking roller, it is generated in the upper and lower side loads with respect to the rotating shaft. The problem is that the position is changed, this problem is caused by the fall or failure of the interlocking wires, the interlocking rollers should always maintain the same position and rotation state. Accordingly, in the present invention, the interlocking rollers 14 and 14 'are inserted into and fixed to the interlocking rollers 14 and 14' on the fixed shaft 19 for strongly supporting and fixing the rail 15. It is possible to maintain a stable installation state.

In particular, since the interlocking rollers 14 and 14 'are mostly covered by the rail 15, they are not only superior in appearance but also coupled to the fixed shaft 19 in which both ends are supported. It is possible to reasonably solve various problems occurring as the rotational central axis changes, as well as prevention.

Accordingly, the rinsing plates 30 and 30 ′ are free sliding while being mounted on the rails 15, and the rinsing plates 30 and 30 ′ are upper parts of the rails 15. Since the separate rinsing rollers 31 and 31 'are mounted on the surface, the rinsing plates 30 and 30' are rinsing rollers 31 and 31 'according to the rotation direction of the interlocking wire 13. The smooth sliding operation is made in the state mounted on the rail 15 through the rotation of the).

Accordingly, the upper part of the doors 40 and 40 'is connected to and fixed to the lower part of the rinsing plate 30 and 30' which receives power from the driving motor 10 disposed in the upper center of the frame 20. The doors 40 and 40 'are simultaneously operated in the open or closed direction.

In addition, the frame 20 is made of a metal plate in the form of a flat plate, and due to its structural characteristics, the warpage is very weak and has a problem of requiring various brackets or ribs to reinforce it. By forming the bent portion 21 in one direction so as to have an inclination angle along the longitudinal direction of the lower end of the 20), the frame 20 of the flat form by the bent portion 21 can ensure excellent bending rigidity will be. Therefore, even using a relatively thin metal sheet material does not interfere with the structural rigidity at all, while providing the handling, manufacturability and ease of installation due to the realization of light weight.

Particularly, in the present invention, the door holding bodies 50 and 50 'are provided to prevent the doors 40 and 40' from being arbitrarily opened or closed, regardless of whether the driving motor 10 is operated at the time of power failure. As being mounted, the door holding bodies 50 and 50 'are coupled to and installed on the frame 20 which is the upper portion of the one side rinsing plate 30'.

Here, the door holding body (50, 50 ') is a state that when the door is fully open or fully closed when the external artificial force is not applied, the state is maintained as it is, power failure during operation If this occurs, the door holding body (50, 50 ') is maintained in the closed state of the door can prevent accidents in advance and if the need to escape the passengers by forcibly opening the door motor Regardless of whether the operation of the device is to maintain the open state to promote safe escape.

Accordingly, in the present invention, as shown in Figure 4, the door holding body 50, 50 'coupled to the frame 20, the cam plate having the guide inlet 51 and the roller receiving portion 52 having an upward inclination angle ( By combining the 53) to face each other to remove the cause of the noise by the cam plate (53) in the form of 'N' shape, it is possible to achieve a smoother operation,

The holding roller 54 is rotated in an up and down direction to the upper side of the rinsing plate 30 'of one of the rinsing plates 30 and 30', but the holding roller 54 is a washing plate ( 30 ') is mounted on the fluidized plate 55 rotatably coupled from the top, the fluidized plate 55 is elastically supported by a separate spring 56, the spring 56 is compact It is preferable that the torsion spring capable of realization of the shoes and the spring 56 tension force be mounted so that the holding roller 54 can receive upward rotational force.

Accordingly, as illustrated in FIG. 5, when the doors 40 and 40 ′ slide and are restrained by the door holding bodies 50 and 50 ′, the holding rollers 54 are inclined upwardly. ), The holding roller 54 and the flow plate 55 are springs 56 by the interference force with the cam plate 53. Will be rotated downward while compressing, while being placed in the roller receiving portion 52 at the moment passing the guide entry portion 51 to maintain the open or closed state of the door as it is.

The doors 40 and 40 'in such a state cannot be separated from the roller accommodation portion 52 until an artificial force is applied due to the shape of the cam plate 53, so as to ensure the safety of the passengers during a power failure or to escape safely. It is possible to maintain the open or closed state as it is.

In addition, in the present invention, when the tension of the timing belt 12 is relaxed in the process of transmitting the power of the drive motor 10 to the rinsing plate 30, 30 'through the timing belt 12 to correct this quickly and effectively As the tension adjusting means for adopting, as shown in Figure 6, the belt pulley 16 on one side is mounted on a separate adjustment plate 18, the adjustment plate 18 is a separate adjustment bolt 23 and the adjustment nut It is made to be able to flow sliding according to the rotation of (24).

That is, the control plate 18 is formed by forming a slit hole 17 in the control plate 18 to which the belt pulley 16 is coupled to the frame 20 through a separate fastening bolt 25. It is possible to flow in the left and right directions within the range of the slit hole 17.

In addition, one side of the adjustment plate 18 is formed as a separate fixing bracket 22 fixed to the frame 20, the fixing bracket 22 and the adjustment plate 18 on one side of the adjustment bolt 23 Inserted through and the adjustment bolt 23 is fastened to the adjusting nut 24 to be fixed to these control plate 18 and the fixing bracket 22 spaced apart from each other.

In this state, the adjusting plate 18 is fixed by rotating the adjusting bolt 23 and the adjusting nut 24 while loosening the fastening bolt 25 fixing the adjusting plate 18. Moving toward (22) eventually increases the tension on the timing belt (12) coupled to the belt pulleys (16, 16 ').

Therefore, when the tension is relaxed due to the change or increase in physical properties of the timing belt 12, the tension adjustment with respect to the timing belt 12 is only performed by rotating the adjusting bolt 23 and the adjusting nut 24 as described above. This is done simply so that the work is very fast and reasonable tension is given.
