Description

Elevator door device

The present invention relates to an elevator door device, so that the deceleration can be performed at the moment of opening and closing the elevator door and the door of the elevator at the same time, by installing a non-powered coupling device in the platform, the variable coupling device in the elevator, If the horizontal position of the lift and the coincidence coincide, the variable coupling device pushes the non-powered coupling device open, and when it is opened for deceleration, it is fully opened by the deceleration switch by the deceleration switch. It relates to an elevator door device.

Conventional elevator entrances generally consist of jambs, lifting doors, landing doors and the like. The relationship between the landing door and the landing door is that when the elevator stops at the landing door, the landing door releases the lock of the landing door and at the same time is combined with the landing door, which is integrated with the opening and closing operation of the landing door to open and close the landing door.

An example of a conventional elevator door apparatus composed of a landing door and a lifting door will be described below with reference to the drawings. After that, unless otherwise stated, only the doors of the lift door and the landing door will be described. 1 and 2 show the back surface of the lift door 4 and the lift door 1 when the lift door 4 and the lift door 1 are closed, respectively. 1 and 2, each landing door 1 is locked by the lock lever (release lever) 3 of the locking device 2 while it is closed. When the elevating door 4 is coupled to the elevating door 1, respectively, the retirement cam 6 on the elevating door side installed at the end of the elevating frame 5 is operated to release the locking of the elevating door 1.

The release roller 9 is provided in the edge part of the header case 7 of the landing door 1 corresponding to the position of the curved section 8 of the retiring cam 6. The header case 7 is provided with the shaft 9B. The release roller 9 is attached to the end of the shaft 9B via the lever 9A, and the release lever 3 is attached to both positions of the shaft 9B. When the curved section 8 of the retiring cam 6 presses the release roller 9, the shaft 9B rotates, and the lock lever 3 releases the lock of the lifting door 1. 3 shows the locked state of the retirement cam 6 and the landing door 1 when the landing door 1 is closed and the ascent is running. FIG. 4 shows the retiring cam when the landing door 1 is opened. 6) and the unlocked door 1 is shown.

The locking mechanism of the landing door 1 has the following structure. When the landing door (1) is closed and the hoist is running, the retiring cam (6) at the top of the hoisting frame (elevator) excites the solenoid (electromagnet) 10 and lifts the rod 11 to lift the curving section 8 It is in a state of repulsion.

As the lift stops, the solenoid 10 of the retiring cam 6 is released by the command of a written control device (not shown), so that the spring 12A pushes the rod 11 downward and the link 12B The curved section 8 is pushed forward by the rotation of. Next, this curved section 8 pushes the release roller 9 of the landing door 1 as shown in FIG. 4, the shaft 9B rotates counterclockwise through the lever 9A, and the landing door ( The lock lever 3, which restrains the movement of 1), rotates in the counterclockwise direction, and the lock of the landing door 1 is released. While the landing door 1 is open, the curved section 8 continues to push the release roller 9.

When a command is given to close the door from a control device (not shown), the solenoid 10 is excited and the rod 11 is lifted so that the curved section 8 retracts as shown in FIG. 3. Since the force to rotate clockwise in FIG. 3 always acts by the return spring (not shown), the lock lever 9 is rotated and the landing door 1 is locked as shown in FIG.

As shown in FIGS. 1 and 2, the lifting door 1 is coupled to the lifting door 4 by the coupling device 12 of the lifting door 1 and the coupling device 13 of the lifting door 4. That is, when the elevating gate drive device 14 installed on the elevating box frame is operated, the lever 15 rotates counterclockwise so that the pin 17A on the elevating box frame 5 is pointed through the rod 16. The link 17 swings, and the cam 18 integrated with the small link 18A rotates around the support point. The lever 19 of the coupling device 13 then rotates in the counterclockwise direction (when the coupling device 13 is located on the right side of FIG. 1), so that the coupling roller 20 approaches the fixed roller 21. These rollers 20 and 21 sandwich the coupling plate 12 to engage the lift door 4 and the lift door 1.

In the conventional elevator door apparatus configured as described above, the panel of the landing door and the panel of the lifting door are respectively driven near the center of gravity, thereby achieving stable high-speed opening and closing, and increasing the operating efficiency of the elevator. There is the same problem.

Since the retiring cam is provided at the end of the lift frame, the release roller is also provided at the end of the landing door, so that the width of the hoistway is increased.

Since the retiring cam is installed at the end of the elevating frame, there is a risk that the retiring cam has to be worked on the elevating box when installing or inspecting it.

Likewise, when the release roller of the landing door is installed on each floor, there is a danger because the body has to stand out from the lift or the footrest.

While the door is closed, the solenoid must be excited to pull up the curvature, increasing power consumption.

The header case of the landing door has a complicated structure, which raises the cost.

When releasing the locked landing door, a loud noise is generated by the collision between the curving rod and the heze roller.

Since the motor of the elevating door driving device is installed in a state where it is protruded on the elevating box, the work space around it is narrow. In addition, when the link lever rotates, there is a fear that the hand or foot is caught in the link lever.

The present invention is to solve this problem, an object of the present invention is to provide a variable coupling device having a hot plate on one of the fixed plate of the door lift to support the door by interlocking the left and right doors of the lift with a fan belt, By installing the coupling device of the non-powered push roller, it is to provide a low-cost elevator door device that is noiseless and easy to install.

Another object of the present invention is to make a hot plate to form a circle, one of the opening in the middle of the door to open the contact with the push roller, the final moment to close the hot plate side by side to make a space with the push roller opening and closing It is to provide an elevator door device to prevent the safety accident by decelerating.

Still another object of the present invention is to provide an elevator door device that allows acceleration and deceleration with a simple double pitch by providing a switch unit interlocking with a movement of a cam lever lever interlocking with a variable coupling device.

To this end, the present invention is to install a variable coupling device in the elevator door constituting the elevator, the landing door to install a non-powered coupling device interlocking with the variable coupling device to open and close the door with a simple structure,

The doors of the landings are fitted with a non-powered coupling to operate the coupling by means of a spring-loaded rope,

The door of the lift box is provided with a variable coupling device such that the door is opened by a fan belt, but one is fixed and the other is a spaced heat plate spaced from the fixed hot plate, and the operation of the variable coupling device is recognized by the switch unit. To cheat,

When opening the door, the acceleration / deceleration is controlled by the recognition of the switch unit, and the deceleration is carried out at the last opening, and when the door is closed, the elevator door device is used to reduce the width of the hot plate and allow the vehicle to operate naturally safely. to provide.

The fixing plate 279 is in contact with the tab plate 277 while supporting the fixing bolt 263, and functions to allow the cam plate 278 to rotate, so that the fixing plate 279 can be formed to be integral with the tab plate 277 when necessary. . 220-1 is an auxiliary hot plate lever for hinge-bonding to open the hot plate 211 to the hot plate hinge pin 212 at the hot plate lever 220 upper position to assist the opening of the vertical hot plate 211.

In the present invention configured as described above, the doors 100 and 200 are normally closed as shown in FIGS. 5 and 6, and when the user opens and lifts the elevator door and goes up or down to the desired floor, the hot plate of the lift shown in FIG. 6 ( 210, 211 is brought between the first and second push rollers 125, 142 of the platform shown in FIG. In this state, when the motor 271 is operated by pressing the open switch in the elevator (elevating box) or by an open command outside the platform, the fan belt 281 moves in the direction of the arrow to open the door fixing plate 201. In this case, the vertical heat plate 211 of one side that is opened is the cam plate lever 260 as shown in FIG. 7 while the cam plate 250 moves from the position of the first cam groove 251 to the position of the second cam groove 252. It rotates in a counterclockwise direction about the pin 214, which is spaced apart as shown in FIG. 7 so that the vertical heating plate 211 is spaced apart from the fixed vertical heating plate 210.

Previously, in the first push roller 125 of FIG. 5, the fixed vertical hot plate 210 of FIG. 6 is pushed to the right, and the hook bar 120 rotates counterclockwise about the hinge pin 121. By doing so, the hook protrusion 122 to release the hook coupling in the hook hole (131). Therefore, the landing door 100 is opened in the dashed line state as shown by the arrow. The first push roller 125 is pushed to the right side, but the door is opened to both sides of the door fixing plate 110 on the right side under the wire rope 105, the door fixing plate 110 on the left side of the wire rope 105 Since the wire rope 105 is moved to the counterclockwise direction because it is fixed on the upper side is to open each door (100). The initial opening is opened in this way, and in the middle, the state changes from the state of FIG. 6 to the state of FIG. 7A, because the cam plate lever 260 comes near the vertical position of the switch shaft 262, and the cam plate 250 is the cam hinge pin 253. Rotate in a counterclockwise direction to rotate the hot plate lever 220 counterclockwise about the hot plate lever hinge pin 214 while the cam roller 240 abuts on the second cam groove 252. However, the hot plate lever 220 is flow-bound to the hot plate lever support plate 230 (door fixing plate 201) by the hot plate lever hinge pin 214 in the center, and the bottom plate is flow-bound to the vertical hot plate 211, Figure 7a and Likewise, the hot plate 211 is opened. Of course, the degree of flaring is to make the interval between the push rollers (125, 142) shown in FIG.

Part of the features of the present invention is to reduce the speed until the door is closed to some extent as shown in Figure 7a to contribute to the safety of the user to prevent the pinching of hands or hem, etc. bar for this purpose Use Sokcam (C). The acceleration / deceleration cam C forms an inclined cam portion 278-5 at an interface between the large diameter portion 278-4 and the small diameter portion 278-3 of the cam plate 278, which is interlocked with the inclined cam portion 278-5. It functions to drive the limit switch 276 having a movable rod (276-1). In the case of FIG. 9, the opening / closing position and the deceleration / deceleration position are recognized by changing the phase of each acceleration / deceleration cam C. For example, the end portion of the large diameter portion 278-4 of the acceleration / deceleration cam C is When the movable rod 276-1 is in contact with FIG. 9, the corresponding limit switch 276 is operated, which is recognized as a closed state by a controller (not shown), and the acceleration / deceleration cam C2 is

Closed deceleration before closing (in this case, of course, the limit switch 276 of the corresponding switch SW1 should be in contact with the end position of the large diameter portion 278-4, such as the acceleration / deceleration cam C1). ) Is recognized as an open deceleration, and the acceleration / deceleration cam (C4) is recognized as an open, for this purpose is installed with a phase difference.

In particular, an advantage of the present invention is that the tab plate 277 and the cam plate 278 abut the acceleration / deceleration cam C, but the tab plate 277 has a radial tap hole 277-1, and the cam plate 278 has a long hole 278-1. Thereby, to adjust the phase angle (position of the large diameter portion 278-4 and the small diameter portion 278-3) of the cam plate 278 through this and to adjust the adjustment screw 278-2 to maintain the adjusted angle This makes it easy to make the necessary adjustments. Therefore, when the cam plate lever 260 shown in FIG. 6 rotates in the clockwise direction while the door is opened, the switch unit 275 is rotated counterclockwise in FIG. 9 (the upper end of the switch shaft 262 of FIG. 9 (right side). The cam plate lever 260 operates integrally from the outside), and in the state of FIG. 6, the end of the large diameter portion 278-4 of the acceleration / deceleration cam C1 of FIG. 9 is the movable rod 276-of the limit switch 276. 1) push to achieve the state. In addition, as shown in FIG. 7A, when the door is opened and fully opened, the end of the large diameter portion 278-4 of the acceleration / deceleration cam C3 of FIG. 9 is moved to the limit switch 276 of the corresponding switch SW3. Is pushed (not shown in FIG. 9 but it will be seen that it operates to phase out with rotation of the switch shaft 262). Then, the control unit (not shown) recognizes the switch and turns on the motor 271 shown in FIG. 7A to decelerate and closes the decelerated state.

Then, when the door is fully opened as shown in Fig. 8, the large diameter portion 278 of the corresponding acceleration / deceleration cam C4 is not shown, although the switch portion 275 in Fig. 9 in which the switch shaft 262 is also rotated and closed is shown at this time. The end of -4 actuates the limit switch 276 of the corresponding switch SW4 to inform the controller that the door is completely open so as to stop the operation of the motor 271. In this case, the present invention has a weight body 262 at the upper end of the cam pan lever 260, and performs an auxiliary function to reduce the power of the motor 271 of the opening and closing opening and closing to enhance the durability of the motor, opening and closing operation Provides a softening effect.

In addition, according to the present invention, when the door is opened and closed at the beginning, the high speed is initially closed in the state of FIG. 8, and then the vertical heat plate 211 pushes and closes the second push roller 142 as the state of FIG. 7A passes. By reducing the distance (d) between the hot plate (210,211) between the action of the) provides a slowing effect to naturally push the second push roller 142. In addition, the present invention is the end of the large diameter portion (278-4) of the acceleration and deceleration cam (C2) shown in Figure 9 by the operation of the switch unit 275 due to the interlocking of the cam plate 250 and the cam plate lever 260 from the state of FIG. By turning on the movable rod 276-1 of the limit switch 276 of the corresponding switch SW2, the control unit decelerates the rotation of the motor 271 to reduce the closing boil speed, thereby causing the fingers to be caught in the closed door 200. Prevent accidents such as back. In this case, when closing the landing door 100, the tension force of the tension spring 113 is applied through the return rod 112, so the power is naturally applied through the roller 110 so that the landing door 100 is closed. Even when it is closed, the landing door 100 is closed. Once the closing is completed, the hook protrusion 122 is coupled to the hook hole 131 of the hook coupling plate 130 to fix the closing of the landing door 100 to the landing frame 103 so that a safety accident can be put on. Make sure

In addition, in the present invention, when the lift door 200 is closed, the auxiliary stopper 290 contacts the stopper roller 293 and performs the stopper function. In this case, the auxiliary stopper 290 is formed by the respective cams 291-1 and 291. -2, 291-3), which provides the stopper function smoothly and strongly by repeatedly providing friction like the ABS function of automobile brakes. This allows the roller fixing plate 294 supporting the stopper roller 293 to provide a spring force to the other end with the spring 297 at the other end of the center fixed plate hinge 295. When the final closing, the closing switch pusher 286 pushes the closing switch 287 on, so that the motor 271 stops completely.

As described above, the present invention allows the doors of the landing and the hoists to be supported by wire ropes and fan belts on the closed loop, respectively, so that the doors of the landing and the hoists can be opened and closed with one lifting power.

Use the vertical hot plate of the elevator as a group, one fixed and the other hot plate to open and close in conjunction with the cam plate, to open and close the deceleration function when the switch is opened, and to open the door of the landing Closes and closes the boil at the boil to close the door to reduce the door's closing at the boil so that the boil deceleration can be closed without a separate control device.

In addition, the hook door is released when the push roller is pushed by the hot plate to open the landing door, which simplifies the electrical control.

In addition, by opening and closing the opening and closing configuration of the landing door and the door of the landing via one door, it is possible to produce at a low production cost.

In addition, the acceleration / deceleration cam is controlled on the acceleration / deceleration cam plate by using the acceleration / deceleration cam that has the phase difference for each phase to switch the door opening / closing state to the rotation of the cam lever. In the tab plate for rotating and fixing the cam plate, a radial tap hole is provided so that the tap hole and the long hole can be adjusted and coupled with the screw, thereby easily adjusting the phase angle of the cam plate.

In addition, the present invention has an auxiliary stopper on one side of the elevating door to form an uneven cam in the auxiliary stopper, so that the stopper roller abuts on the uneven cam to allow the door to be closed smoothly and safely.

In addition, the present invention puts a weight on the top of the cam lever lever to reduce the load of the cam plate action of the other end to perform an auxiliary function to smoothly operate the initial action to close and open.
