At this time, the vertical reducer 22 is composed of a worm reducer equipped with a bevel gear generally used in the prior art, and a pair of moving brakes by transmitting the driving force of one driving motor 21 to both sides by the worm reducer. (30) reciprocating in the horizontal direction, and accordingly, the emergency braking device of the present invention efficiently moves the pair of movable braking units 30 using one drive motor 21, thereby more stably moving the car ( 200), the effect of enabling emergency braking force to be generated is realized.

In other words, the vertical reducer 22 transmits the driving force of the driving motor 21 by the second driving shaft 21b connected to the second driving shaft 21b and receiving rotational force from the first driving shaft 21a. Receive and rotate the four-wing connection (23).

At this time, the coupling 21c blocks the rotational force of the driving motor 21 when a torque higher than a preset torque, that is, a rotational force, is generated, thereby causing the driving motor 21 to run idle, thereby causing an overload on the driving motor 21. It is characterized in that to prevent it from occurring.

In addition, the coupling 21c, that is, the torque limiter coupling, is completely when the moving braking unit 30, which will be described later in detail, is moved in the horizontal direction so that the braking pad 31 is pressed against the fixed pad 11 When the drive motor 21 is pressed in close contact, the drive motor 21 is no longer rotated and an overload may occur, but by blocking the rotational force of the drive motor 21 to cause the drive motor 21 to spin away, the drive motor 21 ) To prevent the overload.

In addition, the coupling (21c), that is, the torque limiter coupling, reached a limit point in which the moving braking part 30 is moved horizontally and the braking pad 31 is released from the fixed pad 11 by compression.

Since it is rotated in the forward and reverse direction, as described above, when the braking pad 31 is compressed or released from the fixed pad 11, the occurrence of overload is primarily prevented, but the detection sensor 40 is malfunctioning or damaged. In this case, an overload may occur in the drive motor 21, and in this case, the second overload is prevented from occurring in the drive motor 21 by the coupling 21c, that is, a torque limiter coupling.

In addition, the driving motor 21 of the present invention is characterized in that it is stopped when the rotational force is blocked by the coupling 21c, which is, as described above, the driving motor 21 by the coupling 21c. When the rotational force of the first driving shaft 21a rotated by) is blocked so that it is not transmitted to the second driving shaft 21b, a signal generated by a torque higher than a preset torque in the coupling 21c is transmitted to the driving motor 21. Is transmitted, and the driving motor 21 is stopped by the signal, so that even if any one of the compression sensor 42 or the compression release sensor 44 among the detection sensors 40 is broken, the driving motor 21 returns to the forward direction or By allowing it to be rotated in the reverse direction, it is possible to realize the effect of allowing the emergency braking force to be normally generated or released in the car 200 even if immediate maintenance is not performed.

It is preferable to use a type that blocks the rotational force of the first drive shaft 21a by making it fall apart. This is when the rotational force of the drive motor 21 is blocked by the coupling 21c, the movement of the joint is sensed. It is to stop the driving motor 21, and at this time, it will be apparent that a movement detection sensor (not shown) that detects the operation of the joint is provided in the coupling 21c, and a detection signal is received from the movement detection sensor. It will be apparent that a control unit (not shown) capable of stopping the drive motor 21 may be further provided.

In other words, the detection sensor 40, that is, the compression sensor 42 and the compression release sensor 44 are installed on the top of the car 200, and are installed to be located on the side of the horizontal moving part 33 Thus, by detecting the horizontal movement of the horizontal moving part 33, the driving of the driving motor 21 is controlled, thereby preventing an overload from being generated when the driving motor 21 is driven.

In addition, the detection sensor 40 may be any commonly used proximity sensor or limit sensor, etc., and the horizontal moving part 33 protrudes in the lateral direction, and corresponds to the detection sensor 40 It will be apparent that the driving motor 21 includes a sensing unit 33h that can be detected, and the driving motor 21 is driven in the forward or reverse direction when the sensing unit 33h is detected by the sensing sensor 40.

That is, the elevator clamping and emergency braking device for preventing door opening and sagging of the present invention basically compresses the braking pad 31 to the fixed pad 11 by the driving motor 31 to generate an emergency braking force or , When the pressure is released to release the emergency braking force, and when the braking pad 31 is compressed to the fixed pad 11 to generate the braking force, the driving motor 31 is moved so that the braking pad 31 is moved by a preset distance. By controlling using the compression sensor 42, the occurrence of overload is prevented, and when the emergency braking force is released by releasing the braking pad 31 from the fixed pad 11, the braking pad 31 is provided by a predetermined distance. By controlling the driving motor 21 using the compression release sensor 44 so that the movement is carried out, the effect of minimizing the reduction in the service life due to the overload by preventing the occurrence of overload is realized.

In addition, the present invention consequently prevents the occurrence of overload of the drive motor 21, so that the drive motor 21 is operated in a state in which the overload is generated, so that the vertical reducer 22, the connection part 23, and the transfer screw 32 , The horizontal moving part 33, the braking pad 31, the fixing pad 11, etc. to realize the effect of preventing the occurrence of a failure in parts.

In connection with the above, the braking pad 31 of the present invention is installed in the moving braking unit 30 to be compressed and released by the fixed pad 11, thereby generating an emergency braking force in the car 200 or the car 200 By releasing the emergency braking force generated in the fixed pad 11 due to the possibility of reciprocating movement due to the driving force of the driving motor 21 together with the moving brake unit 30, that is, by rotation of the transfer screw 32. It is characterized in that whether or not crimping is determined, and a pressing force against the fixed pad 11 is formed by a pressing force by the driving force of the driving motor 21 to generate an emergency braking force.

That is, the braking pad 31 of the present invention has a configuration in which a pressing surface corresponding to the pressing surface of the fixed pad 11 is formed, and while the car 200 is raised or lowered in the elevator chamber 110, the In a state in which the pressure on the fixed pad 11 is released, and in a state in which the car 200 is positioned on a specific floor 120 and stopped, the moving brake unit ( 30) is moved in the direction of the fixing pad 11 and compressed.

At this time, when the car 200 in a state of being stopped on the specific floor 120 is operated to move up or down again, the driving motor 21 is reversed to the above before the up and down movement of the car 200. 31) is moved away from the fixing pad 11, that is, in the direction opposite to the fixing pad 11, in the inner direction of the car 200, in a reverse rotation that moves the brake part 30 and the brake pad 31 together. It is operated to release the compression between the fixed pad 11 and the braking pad 31.

In addition, the fixed pad 11 and the brake pad 31 are horizontally positioned in the direction of the fixed pad 11 when the car 200 is positioned on a specific floor 120 and stopped. It is moved to form a compression force, and even if a heavy object is mounted on the car 9200 in the above state, the car 200 prevents any tensile force on the wire 210 from being applied at all, apart from the brake device on which the elevator system is basically installed. (200) can be clamped in the interior of the elevator chamber (110).

At this time, since the car 200 is stopped by the fixing pad 11 and the braking pad 31 does not apply any load to the wire 210 that moves the car 200 up and down, the weight of the wire 210 There is no sagging of the wire 210 due to the mounting of the wire 210 at all, and due to the moment of the car 200 due to the sagging of the wire 210 or continuous downward sagging, the floor surface of the car 200 and the floor 120 It realizes the effect of preventing the occurrence of a step 150, that is, sagging between the floor surfaces.

In addition, the fixing pad 11 and the braking pad 31 may be configured in various forms as long as they can form or release mutual pressing force, but in the present invention, the fixing pad 11 and the braking pad 31 It is characterized in that a plurality of racks (11a, rack) having a length in a direction perpendicular to the longitudinal direction of the elevator chamber 110, that is, orthogonal to the pressing surface, are formed.

In more detail, a direction perpendicular to the longitudinal direction of the elevator compartment 110, that is, a fixing pad 11 and a braking pad 31, is provided on each of the pressing surfaces of the fixing pad 11 and the brake pad 31. It is characterized in that a plurality of racks (11a) having a length in a direction perpendicular to the longitudinal direction (up-down direction) are formed, and the rack (11a) of the fixing pad (11) and the rack of the brake pad (31) ( 11a) realizes the effect of generating a braking force when the braking pads 31 are pressed against the fixed pads 11 by being pressed against each other and engaged with each other.

At this time, the rack (11a) may be configured to protrude from the pressing surface of the fixing pad (11) and the braking pad (31) or a fine shape, it is preferable to be configured in a protruding shape in consideration of durability.

In addition, the length of the rack 11a may be formed in a straight line or divided into a plurality in the width direction of the fixing pad 11 and the braking pad 31 according to the judgment of a person skilled in the art, and the rack 11a It is preferable that the fixed pad 11 and the braking pad 31 are formed in a vertical direction in a multi-layered direction and configured such that a plurality of irregularities are formed can generate a stable braking force.

That is, when the car 200 is positioned on a specific floor 120 and stopped, the rack 11a is a pressing surface of the rack 11a and the braking pad 31 formed on the pressing surface of the fixed pad 11 The rack (11a) formed on the rack (11a) formed in contact with each other and is configured to be fitted, and the fixed pad (11) due to interference by fitting between the rack (11a) formed on the fixing pad (11) and the rack (11a) formed on the brake pad (31) The compression force between the braking pads 31 is increased, thereby realizing the effect of allowing the car 200 to be more firmly clamped inside the elevator compartment 110.

The result of the fixing pad 11 and the braking pad 12 being in contact with each other and being fitted together is by clamping the car 200 inside the elevator compartment 110, thereby generating an emergency braking force, and the door due to a malfunction of the elevator system. When the car 200 is started, that is, moved in the open state, by generating a strong emergency braking force on the car 200, the effect of preventing the car 200 from being started is realized.

In addition, the size, shape and protrusion height of the racks 11a, that is, between the racks 11a, that is, the pitch, etc. can be appropriately adjusted according to the use and size of the elevator system in which the apparatus according to the present invention is mounted. It will be self-evident.

In addition, the rack 11a is characterized in that the distal end is formed in a curved form, which is a fixed pad when the distal end is formed in a curved form compared to that of a general rack having a sharp end or an edge formed. 11) When the braking pad 31 is moved and compressed, when the car 200 sags downward by a heavy object, the end of the rack 11a of the braking pad 31 is the rack of the fixed pad 11 When it comes into contact with the end of (11a), the brake pad 31 is formed by the curved end surface of the rack 11a of the brake pad 31 and the curved end surface of the rack 11a of the fixing pad 11 As the car 200 is naturally squeezed on the fixing pad 11 and moved to the correct position, it is possible to further prevent the occurrence of the step difference of the car 200 and realize the effect of generating a stable emergency braking force. have.

In addition, in the present invention, when a heavy object is moved to the inside of the car 200 in a state in which the car 200 is correctly positioned on a specific floor 120, the car 200 in the correct position is the wire 210 and Since the emergency braking device of the present invention maintains the same horizontal level as the floor 120, the effect of preventing downward sagging is realized.

In addition, the present invention prevents the car 200 from starting, that is, moving due to a malfunction of the elevator system in a state where the car 200 is positioned on a specific floor 120 and the door 140 is opened. By preventing through the coupling of the rack 11a of 31) and the rack 11a of the fixing pad 11, the effect of preventing the occurrence of a safety accident is realized.

In addition, the present invention is operated in a more efficient configuration by horizontally moving the pair of movable braking units 30 using one driving motor 21, it is easy to install in the field and can reduce the installation cost. It makes the effect come true.

In addition, although there may be differences depending on the construction method, in most elevator systems, guide rails 100 installed inside the elevator compartment 110 are installed at the centers of both sides of the car 200, and the guide rail 100 A guide device 300 is installed on the guiding protrusion 101 protruding in the middle of the car 200 to support the vertical movement of the car 200 stably,

Accordingly, the elevator clamping and emergency braking device for preventing door departure and sagging according to the present invention forms a branch part 33a to facilitate installation in the upper center of the car 200, as shown in FIG. 11, As a result, since it is easy to install in connection with the guide device 300, it makes it easier to install in the field.

In addition, the present invention is installed in the upper center of the car 200 by the branch portion 33a, so that the horizontal state of the car 200 is maintained more stably and the emergency braking force is generated, the car 200 It realizes the effect of preventing sag from occurring in the left or right downward direction by the movement of the heavy object.

In addition, the fixed position clamping and emergency braking device for preventing elevator sagging according to the present invention, through the coupling by compression between the fixed pad 11 and the brake pad 31 described in detail above, the main brake device of the elevator system is broken or It can also be used as an emergency braking system in case of a damaged emergency.

In addition, the control for the operation of the driving motor 21 according to the present invention can be integrated and managed through a control unit provided in the elevator system, and in particular, a braking pad for the fixed pad 11 by the operation of the driving motor 21 The crimping and releasing of (31) may be automatically controlled by the control unit when the car 200 reaches the correct position on the floor 120 of the building, or may be manually operated by the administrator.

The above has been described with reference to a preferred embodiment of the present invention, and is not limited to the above embodiment, and through the above embodiment, those of ordinary skill in the art to which the present invention belongs do not depart from the gist of the present invention.
