Description

  The present invention relates to an elevator safety device, and more particularly to an elevator safety device that prevents a car from moving beyond a predetermined value when a car door is open.

  There is a possibility that the brake lining of the elevator wears abnormally and the brake stop force becomes incomplete. In such a case, even though the elevator car has landed on the landing, stopped, and opened the door, the difference between the weight of the car and the counterweight could not be supported by the hoisting brakes, and the car was raised or There is a possibility of descent. As a countermeasure against such an inconvenient movement of the car, it has been proposed to provide a rope brake between the hoisting machine and the deflecting wheel for holding the hoisting rope and stopping the car.

  The rope brake is released by hydraulic pressure during normal operation and does not hinder the operation of the cage, but operates when the cage moves outside the normal landing door zone (normally ± 100 to 200 mm) with the cage door open. And it is comprised so that a hoisting rope may be gripped and the movement of a cage | basket may be prevented (for example, refer patent document 1).

  In addition, cams and landing detection members are provided on the landing doors and landing door devices so that the elevator car can be opened when the elevator car is near the landing, so that the car can be opened at a position away from the landing. A car door locking device that prevents the door from opening is already known (see, for example, Patent Documents 2 to 4).

Japanese Patent Application No. 2003-155174 U.S. Pat. No. 4,313,525 U.S. Pat. No. 4,364,454 Japanese Patent Publication No.59-30638

  However, in the conventional rope brake type elevator safety device, even if the car goes out of power while the car is running, the rope brake device operates and grips the hoisting rope. Therefore, it may be necessary to replace the rope at the time of recovery.

  In addition, in the case of an elevator without a deflector, a machine room-less elevator in which a hoisting machine is installed on a climbing road, or a hydraulic elevator, it is difficult to secure an installation space and it is difficult to mount and install a rope brake. .

  Further, the rope brake device needs to be arranged at an appropriate rope angle between the drive sheave of the machine room and the deflecting wheel so as to generate a sufficient stopping force. For this purpose, it may be necessary to raise the machine base or change the position of the deflector in the height direction. When a rope brake is added to an existing building, a large cost such as construction costs may be incurred due to the construction or change of the machine stand such as increasing the ceiling height of the machine room. It was.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator safety device that can easily be installed in an existing elevator without damaging the hoisting rope even if a power failure occurs while the car is running.

  The elevator safety device according to the present invention is provided at a position corresponding to the non-lock zone plate provided on the door of the landing on each floor and the non-lock zone plate on the car door, and is not in contact with the non-lock zone plate. A lock lever movable between an inoperative position and an actuated position in contact with the non-lock zone plate; and a stop that is actuated by movement of the lock lever to the actuated position to prevent movement of the car. And a car stopping device.

  According to the elevator safety device of the present invention, the car door locking device is used, and the car is provided with a device for stopping the car when the car is deviated from the landing with the car door open. Even if a power failure occurs, the hoisting rope is not damaged, and it can be easily installed in an existing elevator.

Embodiment 1 FIG.
1 to 4 show an elevator safety device of the present invention. FIG. 1 is a schematic configuration diagram illustrating a state where the car 6 is normally landed on the landing with the car door 64 fully closed. FIG. 2 is a view showing a state where the car 6 is normally landed on the landing and the car door 64 and the landing door are engaged and fully opened. FIG. 3 is a view showing a state in which the car 6 is moved upward by A dimension or more and B dimension or less with the car door 64 opened. FIG. 4 is a view showing a state in which the car door 64 is opened H on one side from the car 6 while the car 6 is traveling on the hoistway.

  In the figure, 61 is a car frame of the car 6, and a car room 62, a car floor (not shown), a car door device 63, and the like are attached to the car frame 61. Reference numeral 64 denotes a car door, which is fixed to a door hanger 66 installed open and closed by a door hanger roller along a rail 65 of the car door fixed to the car door device 63. Reference numeral 67 denotes a movable vane fixed to the car door 64. The movable vane 67 includes a landing door tsunami roller 201 and a landing door tsunami fixed to a landing door (not shown) on the floor installed at a position facing the car door 64 when the elevator is landing on the landing. Arranged so as to be located between the blocks 202. When the car door 64 is opened by a size G (a distance between the movable vane 67 and the landing door dent roller 201), the movable vane 67 contacts the landing door dent roller 201.

  When the door 64 of the car further opens from this position, the landing door tsunami roller 201 is pushed, and although not shown, the landing interlock is opened by the lever link mechanism to open the landing door. Will be able to. Further, when the car door 64 moves about 100 mm, the movable vane 67 is moved to the left and right by a link mechanism (not shown) so that the interval is increased and the landing door dent roller 201 and the landing door dent block 202 are pushed. Even if the combination is completed and the car door 64 is accelerated and decelerated such as opening and closing reversal, the car door 64 and the landing door are opened and closed together (see FIG. 2).

  68 is a car door lock device. The car door locking device 68 does not prevent the car door 64 from opening when the car door 64 is opened when the elevator car 6 is in the vicinity of the landing zone of the landing, but the car 6 is landing on the landing. This device prevents the car door 64 from opening when the car door 64 is to be opened when the car door 64 is located far away from the floor zone.

  Reference numeral 203 denotes a non-lock zone plate installed at a landing door (not shown) on each floor. It is set to detect about A = 500 mm from the normal landing position. The non-lock zone is set as large as ± 500 mm with respect to the vane zone ± 300 mm corresponding to the length of the movable vane 67. When the car 6 is normally landed, the non-locking roller 6801 installed at the tip of the substantially “く” -shaped lever 6802 fixed to the car door 64 so as to be rotatable about the axis 6803 is arranged in the vertical direction of the non-locking zone plate 203. It is installed so as to be located through the gap E at the center position. The gap E is set slightly smaller than the gap G.

  A stopper 6804 that fixes the counterclockwise rotation of the lever 6802 is installed on the car door 64 so that the gap E can be adjusted. A spring 6805 applies torque to the lever 6802 around the axis 6803 in the counterclockwise direction. A lever 6806 extending upward is connected to the other end of the lever 6802, and is connected to a lever 6807 that is rotatably fixed to the hanger plate. A roller 6808 is rotatably installed at the tip of the lever 6807.

  A horizontal cam plate 6810 is provided at a position where the roller 6808 contacts and pushes up. The horizontal cam plate 6810 is arranged so that it can be moved up and down by a lever 6812 and a lever 6813 so as to form a rotatable parallel link from the car frame 61. The lever 6812 is configured so that the rotation range can be limited and adjusted by a stopper 6817 provided on the car frame 61. The lever 6813 is torqued so that the horizontal cam plate 6810 is always biased to a lower position by a spring 6814. Is given.

  A roller 6811 is rotatably fixed to the horizontal cam plate 6810 and is provided so as to contact a cam 6809 fixed to the door hanger 66. When the car door 64 is in the vicinity of the fully closed position, the cam 6809 fixed to the door hanger 66 pushes up the roller 6811 and pushes up the horizontal cam plate 6810.

  A stopper 6815 is fixed to the horizontal cam plate 6810. When the car 6 tries to open the car door 64 at a position away from the regular landing position by ± A or more, there is no non-lock zone plate 203 at a position facing the non-lock roller 6801 at that position. 6801 does not rotate the lever 6802 clockwise. When the car door 64 is opened as it is, the roller 6808 is in a position where it does not push up the horizontal cam plate 6810 in the position where it is lowered, so when the roller 6811 is disengaged from the cam 6809 (about 15 mm), it moves downward. Accordingly, the horizontal cam plate 6810 is also lowered. Then, since the stopper 6816 installed on the door hanger 66 hits the stopper 6815 installed on the horizontal cam plate 6810 at H (about 20 mm), the car door 64 cannot be opened beyond the H dimension.

  Reference numeral 70 denotes an entrance / exit column of the car 6, and 71 denotes an entrance / exit center. Reference numeral 100 denotes a car stop device, which stops the car 6 when the car 6 moves due to the brake being disabled due to abnormal wear of the brake or the like with the car door 64 open. Reference numeral 101 denotes a lever connected to the lever 6813 of the car door lock device 68. When an abnormality occurs (the car 6 has moved from the landing position above the non-lock zone ± A and the car door 64 is opened), the lever 6813 is The lever 101 is pushed leftward by rotating counterclockwise around the fulcrum on the car frame 61. The pin 101-1 is fixed to the lever 101-101-1. In this sense, the lever 6812 and the lever 6813 are link mechanisms that convert the vertical movement of the horizontal cam plate 6810 into the horizontal movement of the lever 101 (stopper 102).

  Reference numeral 102 denotes a stop tool which, when pushed by the lever 101, moves within the guide 103 fixed to the car frame 61 and protrudes outside the car 6 from the D state from the normal state. When the stop tool 102 protrudes, the switch 104 operates. The upper stopper 105 and the lower stopper 106 that are stopped when the car moves ± B (about ± 1000 mm> ± A = 500) are fixed to the guide rails of the hoistway in the vertical direction from which the stopper 102 protrudes. Each of the upper stopper 105 and the lower stopper 106 is arranged so as to collide with the C dimension in a state where the stopper 102 protrudes with the D dimension.

  In addition, when an elevator is used in an emergency, firefighters may use the elevator for fire fighting activities even in the event of a building fire. In this case, the car door 64 may be opened and the elevator car 6 may be moved up and down. In this case, when an operation panel (not shown) in the car room is turned on, the electromagnet of the fire fighting operation coil 107 as a fire fighting operation device is energized, and the lever 6813 is attracted against the spring 6814. In this suction state, the horizontal cam plate 6810 is always held upward, so that even if the car door 64 is opened and the elevator runs, the fire-fighting operation can be performed without the stop 102 protruding.

  A fire fighting operation lever 118 is provided as a second fire fighting operation apparatus for disabling the car stop device 100 during the fire fighting operation. When an operation panel (not shown) in the car 6 is opened and a lever (not shown) is pulled, a pulling force is transmitted to the control wire 118-1, and the fire-fighting operation lever 118 is rotated clockwise in FIG. The fire-fighting operation lever 118 pushes the pin 101-1 fixed to the lever 101 and moves the lever 101 to the right side to prevent the stop tool 102 from protruding. During normal operation, the counterclockwise torque is applied to the fire-fighting operation lever by the push spring 118-2.

  The fire fighting operation lever 107 can be configured without the fire fighting operation coil 107 alone. Further, both the fire-fighting operation lever 118 and the fire-fighting operation coil 107 may be installed, and the fire-fighting operation lever 118 may be used when the electric wire becomes in a malfunction due to a fire. Thus, when an elevator is used by a normal passenger, the car stopping device 100 is made effective, and a specialist who has received an elevator operation training in the event of a fire or elevator maintenance work opens the car door 64. It will be possible to drive while still. As a result, a specialized driver can disable the car stop device 100 and operate the elevator, so there is no need to install a special elevator in the building.

  If the fire-fighting operation device is configured with the fire-fighting operation lever 118 or the like, the car stop device can be disabled with the lever from the operation panel in the car even if the electric wire is half-cut due to a fire. (Power supply is necessary to disable the rope brake device, and it is necessary to operate firefighters in the machine room and cage in the event of a fire.)

  With such a fire-fighting operation device, in the case of a general elevator passenger, it operates as an elevator start prevention device, and in the case of a fire-fighting operation, this safety function can be disabled and the elevator can be used.

  In a normal state that is not a fire, ordinary passengers can also use an emergency elevator with a safety device, and can also use the elevator at a low cost. Further, when the electromagnet of the fire fighting operation coil is turned on during normal operation and the car door is opened after landing on the landing, the electromagnet can be turned off to monitor an abnormal slip of the car.

  With such a configuration, it is possible to prevent a malfunction in which the car stop device operates during elevator travel and destroys the stop device. Car slips can be centrally monitored with the elevator landing and brakes enabled. Of course, the car slip can be monitored by opening the car door even during a power failure.

  As shown in FIG. 2, it is assumed that the car 6 is normally landed on the floor, and the car door 64 is opened by the landing mechanism and the engagement devices (67, 201, 202). . In this case, when the door is opened, the non-locking roller 6801 is pushed by the non-locking zone plate 203, the lever 6802, the lever 6806, and the lever 6807 are operated, and the horizontal cam plate 6810 is raised by the roller 6808. Thus, there is no connection between the stopper 6816 and the stopper 6815, and the door is opened. Further, since the horizontal cam plate 6810 is raised, the lever 101 is on the right side and the stop 102 is pulled to the car side at the normal position.

  From this state, when the passenger gets off the landing and the weight of the car 6 becomes smaller than the weight of the suspension weight, the car 6 is pulled to the weight side due to the maintenance failure of the brakes in the elevator machine room. As a result, the car 6 may begin to rise. This state is shown in FIG.

  In FIG. 3, when the movement of the car exceeds the dimension A (about 500 mm), the non-locking roller 6801 moves away from the non-locking zone plate 203 at the landing, and the lever 6802 rotates counterclockwise. As a result, the lever 6806 is pushed up, the lever 6807 rotates counterclockwise, and the roller 6808 is lowered. Then, the horizontal cam plate 6810 is lowered, the lever 6813 is rotated counterclockwise, and the lever 101 is pushed to the left side. Then, the stop tool 102 protrudes from the car 6 to the left outer side by a D dimension. When the car 6 nose up on the B dimension (about 1000 mm), the stopper 102 collides with the upper stopper 105 to stop the abnormal rise of the car.

  FIG. 4 shows a state in which the car door is locked and prevented from opening by the car door lock mechanism. While the car 6 is traveling at a position away from the landing or in an emergency stop at a position away from the landing, the passenger may try to escape from the car 6 by opening the door 64 of the car. In this way, when the car door 64 is opened at a position away from the landing and escapes from the car, the passenger may fall into the hoistway by mistake.

  In the elevator safety device according to the present invention, when the car 6 is traveling at a position away from the landing or when an emergency stop is made at a position away from the landing, an attempt is made to open the car door 64 as shown in FIG. It will be in the state shown in That is, when the car door 64 is opened to H dimension on one side, there is no non-lock zone plate 203 installed on the landing door near the non-lock roller 6801, so the lever 6802 of the non-lock roller 6801 hits the stopper 6804. State. Since the lever 6806 remains in the raised state, the lever 6807 does not rotate. Accordingly, the roller 6808 is also below and is separated from the horizontal cam plate 6810, and the horizontal cam plate 6810 is pushed up only by the cam 6809 fixed to the door hanger 66, and the height position is controlled.

  When the car door 64 is slightly opened, the roller 6811 rolls down on the force 6809. When the car door 64 is moved to the H dimension, the stopper 6815 fixed to the horizontal cam plate 6810 and the stopper 6816 fixed to the door hanger 66 collide, and the car door 64 is locked and the two car doors 64 are locked. Can open only about 2H (about 40 mm). In this way, it is possible to prevent the car 6 from opening the car door 64 at a position away from the landing and escaping from the car 6 and falling to the hoistway.

  In this state, since the lever 6813 rotates counterclockwise, the stopper 102 protrudes. However, since the horizontal cam plate 6810 is not fully lowered when the car door 64 is moved by the H dimension in this way, the height of the cam 6809 is set and the rotation angle of the lever 6813 is adjusted. At the position, the stopper 102 is adjusted so as to have a gap of J dimension with respect to the stoppers 105 and 106 so as not to collide with the stoppers 105 and 106 arranged on each floor.

  As described above, there are the following merits compared to the case of installing a rope brake.

  Even if there is a power outage while the car is running, the machine detects the door opening of the car and the movement of the car in the mechanical system, so the car can be stopped regardless of the power outage or the rope. The operation of the rope brake device can stop the car without applying a large load to the rope and damaging it. Therefore, it is not necessary to replace the rope at the time of recovery, and the problem of the rope brake device can be overcome.

  In addition, it was difficult to mount and install a rope brake on an elevator without a sorase vehicle, a machine room-less elevator with a hoisting machine installed in a hoistway, or a hydraulic elevator, but with the elevator safety device of the present invention, Since the car safety stop parts are installed near the car, near the landing doors and the rails of the hoistway, existing elevators without a sorase car and machine room-less existing hoisting machine installed in the hoistway A car stop safety device can be easily added to the elevator.

  In addition, the rope brake device must be arranged between the drive sheave in the machine room and the baffle so as to receive a sufficient stopping force by placing it at an appropriate rope angle. In some cases, it was necessary to change the position in the vehicle height direction. When a rope brake device is added to an existing building, a large construction cost may be required to change the building or the machine stand 1 such as increasing the ceiling height of the machine room. It was. However, in the present invention, since the car safety stop parts are installed around the car, near the landing doors and the rails of the hoistway, the machine base is raised or deflected to change the vehicle height direction position, There is no need to change the building or machine base, such as increasing the ceiling height. It is possible to install a safety device for stopping the car in the existing elevator at a low cost.

  As described above, in the elevator safety device of the present invention, first, the non-lock zone plate 203 is installed at the landing door on each floor. The non-lock zone plate 203 is longer than the car door 64 and the landing door engagement zone.

  Second, a non-locking roller 6801 is installed on the car door 64 at a position corresponding to the non-locking zone plate 203. The non-locking roller 6801 is installed with a gap of about 5 mm so as not to contact the non-locking zone plate 203 even when the car 6 passes through the floor. About 10 mm is required until the car door 64 and the landing door are completely engaged.

  Third, the non-locking roller 6801 is rotatably installed on the lever 6802. When the car 6 is within the range of the normal landing ± A (about 500 mm) and the car door 64 is opened, the lever 6802 becomes the car door. It strikes the non-lock zone plate 203 and rotates clockwise.

  Fourth, the lever 6806 is pushed down by the rotation of the lever 6802. When the lever 6806 is pressed down, the car stopping device 100 does not operate as normal. If the car moves over dimension A (about 500 mm) with the door open, the non-locking roller 6801 comes off the non-locking zone plate 203 and the lever 6802 is prevented from rotating counterclockwise by the stopper 6804. The stop 102 of the car stop device 100 protrudes from the car 6 and collides with a stopper 105 or 106 installed in the hoistway to stop the car 6.

  Further, in the elevator safety device of the present invention, if the wear progresses abnormally due to abnormal wear of the brake shoes of the elevator hoisting machine and the friction mechanism becomes incomplete, the elevator car goes to the floor. When the passenger got in and out of the elevator car after landing, it was considered that the brakes failed and the car and the counterweight slipped to the heavier counterweight with the elevator door open. However, when the elevator car moves about 500 mm up and down with the above-described structure, the car stopping device operates to stop the car, so that the car can be prevented from moving completely away from the landing.

  A sheave of a sheave of an elevator hoist that frictionally contacts a wire rope to generate traction force and support a counterweight. However, if the sheave wears abnormally and the traction force decreases, the car that slips on the sheave as described above and the passenger moves up and down with the elevator doors in the open state and the car door open. The danger of being caught in However, when the elevator car with the above structure moves up and down by A dimension (about 500 mm) or more, the car stopping device operates to stop the car at B dimension (about 1000 mm), so the car has landed. It is possible to prevent the vehicle from moving completely away from the landing.

  Previously, when the elevator car door was left open and the car moved up and down, a rope gripper type safety device was proposed that detects the abnormality electrically and releases the electromagnet to sandwich the elevator rope. It had been.

It is the figure seen from arrow VIII-VIII. This elevator safety device is of a wedge type used as an emergency stop by a stop device, and is a schematic configuration diagram showing a structure for stopping a car by grasping a guide rail of the elevator car. Since the elevator door safety device 68 and the like are the same as the elevator safety device shown in FIGS.

  In this elevator safety device, the stop deceleration can be reduced by generating a large stopping force gradually without stopping the car suddenly.

  5 to 8, in the event of an abnormality, the horizontal cam plate 6810 of the car door lock device 68 is lowered, the upper end of the lever 6813 is rotated to the left in FIG. 5, and the lever 108 is pushed to the left in FIG. The movement of the lever 108 is reversed by the lever 109 in FIG. 6, the lever 110 is moved to the right in the figure, and the L-shaped lever 112 is rotated by the lever 111 to move the wedge-shaped stop block 114 in the housing 115 up and down. Move to. The stop block 114 is inserted between the housing 115 and the rail 300 while moving with the steel ball 116 along the inclined inner surface of the housing 115, and the rail 300 is gripped to generate a large stop force. .

  According to this embodiment, since the braking force due to the wedge action is used, the stop of the car does not stop suddenly, but a large stopping force is gradually generated. Can be small.

  Similar effects can be obtained by using fire fighting operation devices such as the fire fighting operation coil 107 and the fire fighting operation lever 118 shown in FIG.

  According to this embodiment, compared with the first embodiment, the impact of stopping the car can be reduced since the stopping device grips the rail. Further, even if there is no emergency power source such as a battery, it can be implemented in the same manner as in the first embodiment, so that it can be configured at low cost.
