Description

Apparatus preventing from breaking away the ascending and descending door of elevator}

The present invention relates to an elevator door side departure prevention device of the elevator in more detail, the present invention is to suppress the bending of the elevator door in the longitudinal direction when a strong impact is applied to the elevator door from the landing side installed on the bottom of the elevator door The present invention relates to an elevator door-side door departure prevention device that prevents the guide shoe from falling out of the guard groove of the lower frame so as not to cause a fall space due to the bending of the elevator door, thereby preventing personal injury caused by the fall accident in advance.

Elevator door departure prevention device of the present invention is to use the elevator door structure that is currently used a lot.

1) Elevator door structure

The elevator door 10 structure is composed of an upper frame 20 and a lower frame 30. The upper frame 20 and the lower frame 30 are firmly fixed to the core wall 60 by the support bracket 40. As shown in FIG. 1, the elevator door 10 is suspended in the upper frame 20 while being positioned in the upper frame 20 and the lower frame 30. The charge of the elevator door 10 is a structure that the upper frame 20 supports. The lower frame 30 serves to guide the elevator door 10 in parallel with the upper frame 20 and is not a member supporting the load of the elevator door 10.

Thus, the upper frame 20 is a structure that supports the entire load of the elevator door 10, the relationship between the upper frame 20 and the elevator door 10 is a solid structure, while the lower frame 30 is an elevator door 10 Since the structure to induce the direction of) and the relationship between the lower frame 30 and the elevator door 10 is not a solid structure.

The relationship between the lower frame 30 and the elevator door 10 will be described below.

In order to guide the direction of the elevator door 10, the guide frame 32 is formed in the lower frame 30, and the guide shoe 12 is installed at the lower end of the elevator door 10 corresponding thereto. Usually, 2 or 3 guide shoes 12 are provided in the elevator door 10.

If the left and right opening and closing of the elevator door 10 is made while supporting the entire load of the elevator door 10 with only the upper frame 20 without the lower frame 30, the bottom of the elevator door 10 has no support force and the upper frame ( 20) becomes the rotation axis, the lower end of the elevator door 10 is opened toward the elevator lift path even in the small impact. This causes a fall accident.

The lower frame 30 is a member that serves to guide the elevator door 10 smoothly in the horizontal direction while preventing the upper frame 20 from becoming a rotating shaft.

A guide groove 32 is formed in the lower frame 30, and a guide shoe 12 is installed at a lower end of the elevator door 10 corresponding to the guide groove 32.

The guide shoe 12 is inserted into the guide groove 32 of the lower frame 30 should be a structure that satisfies two requirements. One requirement should be a structure to prevent the upper frame 20 from becoming a rotation axis, and the other requirement should be a smooth guide structure in the horizontal direction of the elevator door 10.

In order to satisfy this at the same time, the guide shoe 12 is inserted into the guide groove 32, but the guide shoe 12 should be spaced apart from the bottom of the guide groove 32 by d, and close to the side of the guide groove 32. Should be In addition, the inside of the guide shoe 12 is made of steel, but both sides of the steel are made of rubber. Both side rubbers of the guide shoe 12 are used to smooth the guide in the horizontal direction of the elevator door 10 while reducing friction with the side surfaces of the guide groove 32.

In this way, the guide shoe 12 installed at the lower end of the elevator door 10 is not firmly inserted into the guide groove 32 of the lower frame 30, so when the impact is applied to the elevator door 10, the elevator As the door 10 is bent, the guide shoe 12 is separated from the guide groove 32, thereby causing a fall accident.

2) clearance gap between core wall 60 and lower frame 30 (a)

In the process of constructing a high-rise building to install an elevator, a core is first formed. Core is an inner space formed vertically from the top to the bottom of a high-rise building. Core is used as a lift passage. The use of core as the lifting passage of the elevator does not mean that the core is the lifting passage of the elevator. The elevator will move along Shanghai's vertical line. The elevator corridor must be vertical. Otherwise, the elevator collides with the core wall 60 and cannot serve as an elevator.

However, no matter how elaborately the high-rise building constructed of concrete, there is a construction error. This construction error is also applied to the core wall 60 of a high-rise building.

Although the core wall 60 is visually seen as a vertical wall, there is a slight bending due to construction errors, so it is also true that the core wall 60 does not form a vertical line from the top to the bottom. Since the elevator corridor must maintain a vertical line, it is inevitable that a gap gap a occurs between the core wall 60 and the elevator corridor to correct the core wall 60 as a vertical line.

In other words, the lifting passage of the elevator is located at a distance apart from the core wall 60 by a gap a. Accordingly, the elevator door 10 is installed at a position spaced apart from the core wall 60 by a gap a. Since the elevator door 10 is a structure supported by the upper and lower frames 30, the upper and lower frames 20 and 30 are provided at positions spaced apart by the clearance gap a.

3) fixing of the lower frame 30

The upper frame 20 is a member that supports the weight of the elevator door 10.

The upper frame 20 may be installed horizontally while maintaining the clearance gap a from the core wall 60.

The lower frame 30 may also be installed in parallel with the upper frame 20 so as to maintain a clearance gap a from the core wall 60. However, since the lower frame 30 is a guide member for opening and closing the elevator door 10 horizontally and horizontally unlike the upper frame 20, the weight of the elevator door 10 is not transmitted to the lower frame 30 at all. .

The lower frame 30 is firmly fixed to the core wall 60 by the support bracket 40.

At this time, rather than being fixed by the support bracket 40 over the entire section of the lower frame 30, it is fixed by the support bracket 40 only in the section where people ride down, that is, [DL + DR] section as shown in FIG. It is not fixed in the [LL and LR] section. This is because the lower frame 30 is not a member that supports the weight of the elevator door 10 but is simply a member that induces the opening and closing of the elevator door 10. Since the [LL and LR] section of the lower frame does not have the support bracket 40, the bottom of the lower frame 30 of the [LL and LR] section is in a floating state and thus is not disturbed at all.

However, in the entire section of the lower frame 30, that is, the [LL + DL + DR + LR] section, the gap is spaced apart from the core wall 60 by a gap spacing a.

The section where people ride down, that is, the section [DL + DR], is finished and treated with flooring, so there is no visible gap a. Since the [LL and LR] sections are not finished or processed, the clearance gap a remains. However, it is not visible to the naked eye because it is hidden by the core wall 60.

In summary, the elevator hoistway is located at a distance apart from the core wall 60 by a gap a. The elevator door 10 is fully supported by the upper frame 20 and guided horizontally by the lower frame 30.

The top roller 22 of the elevator door 10 is moved to the left and right while being mounted on the upper frame 20, and the guide shoe 12 installed at the bottom of the elevator door 10 has a guide groove of the lower frame 30 ( It is a structure inserted in 32). At this time, the guide shoe 12 inserted into the guide groove 32 of the lower frame 30 is spaced apart by d without being in close contact with the bottom of the guide groove 32. That is, the depth of the guide shoe 12 inserted into the guide groove 32 is approximately 1 to 1.5 cm. Guide shoe 12 is wrapped on both sides of the rubber material. This is to facilitate the movement of the guide shoe 12 in the guide groove 32.

Since the depth of the guide shoe 12 inserted into the guide groove 32 is too thin, when the impact is applied to the elevator door 10, the lower side of the elevator door 10 increases in the longitudinal direction of the elevator door 10. There is a problem that the guide shoe 12 installed in the separated from the guide groove 32 of the lower frame (30). For this reason, the elevator door 10 is bent due to the impact and the elevator door 10 is separated and the crash accident occurs.

The present invention suppresses the warp in the longitudinal direction of the elevator door when a strong impact is applied to the door of the elevator from the landing side to prevent the guide shoe installed at the bottom of the elevator door to escape from the guard groove of the lower frame as well as the guide shoe guard Even if it is dislodged from the home by minimizing the degree of departure, the fall space caused by the bending of the elevator door is also minimized to prevent the fall accident in advance, as well as to prevent human injury caused by this purpose.

The elevator door-side door departure prevention device of the elevator of the present invention, the upper frame 20 that fully supports the load of the elevator door 10 and the horizontal movement of the elevator door 10 without supporting the load of the elevator door 10 at all The guide frame of the lower frame 30 is provided with a lower frame 30 fixed at a position spaced apart from the core wall 60 by a gap spacing smoothly, and a guide shoe 12 installed at the bottom of the elevator door 10. The invention is based on the premise of an elevator assembly structure having an assembly relationship in which (32) is inserted.

According to the present invention, when the strong impact is applied to the elevator door 10, the elevator door 10 is bent in the longitudinal direction while the guide shoe 12 installed at the bottom of the elevator door 10 is a guide groove (of the lower frame 30) 32 is an invention using a guide groove 32 of the lower frame 30, and LL and LR in FIG.

In other words, the landing door departure prevention device of the elevator of the present invention is the relationship between the bottom surface 34 of the guide groove 32 of the lower frame 30 and the guide shoe 12, and the LL of the lower frame 30 and The relationship between the LR section and the clearance gap a is used.

This will be described in detail below.

(1) Departure preventing longitudinal groove 36 formed in the bottom surface 34 of the guide groove 32 of the lower frame 30

The relationship between the bottom surface 34 of the guide groove 32 of the lower frame 30 and the guide shoe 12 will be described.

The guide shoe 12 is a structure that is inserted into the guide groove 32 of the lower frame 30 while being installed at the bottom of the elevator door 10. However, the guide shoe 12 is inserted into the spaced apart state d without being in close contact with the bottom surface 34 of the guide groove 32. The guide shoe 12 is spaced apart by d in order to minimize the friction force between the guide shoe 12 and the guide groove 32. This is because the role of the lower frame 30 does not support the load like the upper frame 20, but merely serves to guide the elevator door 10 in the horizontal direction.

In this way, the insertion structure between the guide shoe 12 and the guide groove 32 is a structure that allows the elevator door 10 to be smoothly guided in the horizontal direction, and is not a structural member that supports the load. The insertion structure with the guide groove 32 is a structure without any structural dynamics. If the insertion structure between the guide shoe 12 and the guide groove 32 has no structural dynamics, the relationship between the guide shoe 12 spaced apart from the bottom surface 34 of the guide groove 32 by d is even greater. It is a structure that has nothing to do with mechanics.

 Since the lower frame 30 is not a member for supporting the load of the elevator door 10, the lower frame 30 may be formed in a portion of the bottom surface 34 of the guide groove 32 in the longitudinal direction to prevent the longitudinal grooves 36 from being separated. There is no problem with the structure and shape of (30).

For convenience of explanation, the lower frame 30 may be divided into a "descent section" which is a "DL + DR" section, and a "moving space" which is a "LL section and an LR section" to open an elevator door 10. In the "LL section and LR section", which is a "moving space", the lower frame 30 is a section in which no load is applied at all. This is because the role of the lower frame 30 serves to guide the elevator door 10 in the horizontal direction. However, the section "DL + DR", the ascending and descending section, is a section in which the load of the elevator door 10 is not taken at all, but a section in which a person gets off the elevator and thus takes a person's weight. The installation of the support bracket 40 supporting the lower frame 30 only in the "elevating section" without installing in the "moving space" is also for supporting the weight of the ascending and descending person.

The separation prevention vertical grooves are not formed in the entire section of the lower frame 30. When the separation prevention vertical groove 36 is formed in the entire section, the lower frame 30 is divided into two because the lower frame 30 cannot be firmly fixed to the core wall 60. The separation preventing vertical groove 36 is most preferably formed only in the "moving space". When the separation prevention vertical groove 36 is installed in the "raising and falling section", the lower frame 30 must support the weight of the person who moves up and down, which is disadvantageous in structure due to the separation prevention vertical groove 36.

Due to the separation prevention vertical grooves 36 formed in the `` moving space '', the structure of the lower frame 30 is weak, or the shape is distorted, so that there is no structural problem.

The lower frame 30 of the `` moving space '' does not support any load and hardly forms a departure preventing longitudinal groove 36 in the lower frame 30 of the `` raising and lowering section '', and the lower frame 30 is This is even more so because it is a member that guides the elevator door 10 in the horizontal direction, and is not a structural material that supports the load of the elevator door 10 at all.

end. Inverted T-shaped release preventing opening 52 associated with the drop-off preventing groove 36 and its shape

The separation preventing longitudinal groove 36 is formed in the "LL section and the LR section" of the lower frame 30 as described above. The inverted T-shaped escape stopper 52 is a structure inserted into the escape stop vertical groove 36.

The reverse T-shaped escape lock 52 has an inverted T shape as shown in FIG. The upper end of the inverted T shape is a vertical portion 522 and the lower end is formed of horizontal protrusions 524 on both sides. The inverted T-shaped vertical portion 522 is fixed to the side frame of the elevator door 10, and the inverted T-shaped horizontal protrusion 524 is inserted into the departure preventing vertical groove 36 of the lower frame 30. . Since the separation preventing longitudinal groove 36 is formed in the "LL section and the LR section", the reverse T-shaped escape prevention opening 52 is installed at the rear of the elevator door 10. An inverted T-shaped escape lock 52 is provided in each of the elevator doors 10.

Inverted T-shaped vertical portion 522 is preferably fixed to the side frame of the elevator door 10 by the fastening bolt.

The reverse T-shaped escape stopper 52 is inserted into the anti-separation vertical groove 36 so that when the elevator door 10 is normally moved left and right, the reverse T-shaped escape stop 52 also moves together.

When a strong impact is applied to the elevator door 10, the force to bend the elevator door 10 in the longitudinal direction acts. An inverted T-shaped horizontal protrusion 524 inserted firmly in the anti-separation longitudinal groove 36 is opposed to a force to bend in the longitudinal direction.

As described above, the escape prevention device of the present invention has a structure in which an upper end of the reverse T-shaped escape stopper 52 is inserted into the elevator door 10, and a lower end thereof is inserted into the escape preventing vertical groove 36 of the lower frame 30. When the elevator door 10 is moved together with the elevator door 10 and is subjected to a strong impact, the elevator door 10 minimizes the fall space against the force to bend in the longitudinal direction. By minimizing the fall space, it is possible to prevent the fall accident in advance.

On the other hand, the inverse T-shaped escape prevention tool 52 is not limited to the inverted T-shape because it consists of an inverted T-shape. As long as the vertical portion 522 is firmly fixed to the side frame of the elevator door 10 while maintaining the inverted T shape, it may be any shape, and the horizontal protrusion 524 is also inserted into the anti-separation vertical groove 36. Any shape may be used as long as the shape can be firmly supported at the bottom of the lower frame 30.

 I. Reinforcement piece (38) to reinforce the gap of the separation prevention longitudinal groove (36) formed in the "moving space" "LL section and LR section"

"LL section and LR section" is a section formed at both ends of the lower frame (30).

Both ends of the LL section and the LR section are formed by the separation preventing longitudinal groove 36. It is necessary to reinforce by the reinforcement piece 38 in the perpendicular direction of the separation prevention longitudinal groove 36 so that both ends of "LL section and LR section" may not open. The reinforcement of the reinforcing piece is preferably fixed after inserting the inverted T-shaped escape prevention tool 52 into the escape preventing longitudinal groove 36.

(2) Departure prevention tool and shape using “gap space a” and “empty space” formed in “LL section and LR section” of lower frame 30

 end. "Gap spacing a" and "empty space" formed in LL section and LR section

In "LL section and LR section", "gap space a" is formed between lower frame 30 and core wall, and "empty space" is formed between lower frame 30 and lifting passage. In this way, the lower frame 30 is wrapped in the "gap a" and "empty space".

The "gap spacing a" is an unavoidable space created by the correction of elevator lift paths to maintain vertical lines and construction errors of buildings.

The empty space associated with the lower frame 30 refers to a space formed on the upper, lower and side surfaces. This space is an unrestricted space. If it is assumed that the support bracket 40 supporting the lower frame 30 is fixed to the core wall 60 of the LL section and the LR section, the lower portion of the lower frame 30 is not an empty space here. This is because the space is limited by the support bracket 40.

Thus, the lower frame 30 of "LL section and LR section" is surrounded by "gap spacing a" and "empty space".

 I. Substructure of the escape prevention zone using “gap spacing a” and “empty space” formed in LL section and LR section

The departure prevention tool of the present invention is a structure in which the lower structure of the departure prevention tool is firmly supported by the lower frame 30. As described above, the reverse T-shaped escape stopper 52 is inserted into the escape stop vertical groove 36 so as to be firmly fixed by the lower frame 30, or the undercarriage of the escape stopper spaces in the lower frame 30. Whether the structure is made to be wrapped by using the support structure by the lower frame 30 is the same way. In either case, all of the upper structures of the escape guards fixed to the side frames of the elevator door 10 are the same in the shape of the vertical portion 522, and the lower structures are supported by the lower frame 30.

The structure in which the substructure of the departure prevention tool surrounds the lower frame 30 by using the “gap spacing a” and the “empty space” is sufficient if it is a quadrangular shape that is slightly larger than the lower frame 30, that is, the “ㅁ” shape. Of course, in this case, the upper structure of the separation prevention tool does not change in the shape of the vertical portion 522.

However, since the direction of impact force is on the elevator hoistway, not all of the “ㅁ” shape is subjected to impact load. It is also possible to modify the substructure to deform the shape of “ㅁ” so as to resist the impact. That is, even when the lower frame 30 is wrapped in the inverse “c” shape instead of the “ㅁ” shape, there is no structural dynamic problem. Whether the lower structure of the release prevention tool is supported by the lower frame 30, whether the shape of the "wh" or inverted "c", is because there is no difference in terms of the impact load direction.

(3) Parallel installation of reverse T-shaped escape stopper 52, “ㅁ” shaped escape stopper 54 and reverse “c” shaped escape stopper 56

In order to prevent the elevator door 10 from being dislodged by a strong impact, one escape guard is installed at one of the elevator doors 10, but as shown in FIG. 1 or 6, the rear of the elevator door 10, that is, the LL section and the LR. It is basically installed in a position close to the section side. The substructure of the separation prevention device installed at the rear of the elevator door 10 may be inverted "T" shape, "ㅁ" shape and inverse "c" shape.

The case where the escape prevention openings are provided in parallel on the front and rear of the elevator door 10 will be described as follows.

On the front of the elevator door 10, it is not possible to install the "ㅁ" shaped escape stop 54 and the reverse "c" shaped escape stop (56). Since the front of the elevator door 10 is installed in the support bracket 40 as a "raising and lowering section", the "ㅁ" shaped escape guard 54 and the reverse "c" shaped escape guard 56 on the lower frame 30. This is because there is no free space for) to move freely.

However, it is much more possible than this to form the separation preventing longitudinal groove 36 in the guide groove 32 of the lower frame 30 in the "raising section". If so, only the reverse T-shaped escape lock 52 can be installed in front of the elevator door 10.

The rear of the elevator door 10 does not matter whether the reverse T-shaped escape stop 52, the "wh" shaped escape stop 54 and the reverse "c" escape stop 56. "Gap a" and "empty space" are formed. 6 and 7 exemplify the parallel arrangement and installation of the escape prevention tool.

The upper vertical part of the escape lock is firmly fixed to the frame of the elevator door and the inverted “T” horizontal projection at the bottom is inserted into the escape slot of the lower frame, or the letter “W” or reverse “B”. Since the escape-preventing shape of the shape surrounds the lower frame, the elevator door is prevented from bending in the vertical direction due to the strong impact, so that a fall space does not occur, thereby preventing human injury.

Since the lower part of the escape prevention device of the present invention is formed with a structure that is firmly supported by the lower frame while being moved together with the elevator door, there is a double effect that the elevator door is smoothly guided in the horizontal direction and at the same time prevents the fall space in advance. .

Since the lower structure of the release prevention device of the present invention is firmly supported on the lower frame, it is a useful invention having the effect of preventing the guide shoe fixed to the elevator door from being separated from the guide groove of the lower frame.

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

With reference to the drawings, the configuration of the landing side door departure prevention device of the elevator will be described.

The elevator door 10 installed on the landing side is opened and closed from side to side so that a person can get on and off. The roller 22 is fixed to the upper end of the elevator door 10, the roller 22 is installed on the upper frame 20. Left and right opening and closing of the elevator door 10 is made by the movement of the roller 22 connected to the wire rope 24. This is an opening and closing method of the elevator door 10 that is commonly used.

The lower frame 30 is fixed to the core wall 60 by the support bracket 40 while maintaining the “gap spacing a” from the core wall 60. The support bracket 40 is installed only in the "descent section" "DL + DR" section, the "moving space" "LL section and LR section" is not the support bracket 40 is installed.

Now, the basic installation of the departure prevention tool will be described.

The vertical part of the release prevention fixture is firmly fixed to the side of the elevator door 10 by a fastening bolt. In the case of the inverted T-shaped escape stopper 52, an inverted “T” shaped horizontal protrusion is inserted into the escape preventing vertical groove 36 of the lower frame 30. If the separation preventing longitudinal groove 36 is formed in the "LL section and the LR section", it is preferable to reinforce the gap by the reinforcing piece 38 at both ends of the "LL section and the LR section".

Departure preventing vertical groove 36 is formed on the bottom surface 34 of the guide groove of the lower frame (30). If the elevator is already installed and used in the existing, it is enough to form a vertical groove 36 to prevent separation in the bottom surface 34 of the guide groove of the lower frame 30. If a new elevator is installed in the factory in advance to form a separation preventing vertical groove 36 in the bottom surface 34 of the guide groove of the lower frame 30, the construction of the separation prevention device is easy.

In the case of the “ㅁ” shaped escape stopper 54 or the reverse “c” shaped escape stopper 56, it can be used only in the “LL section and LR section”. This is because the support bracket 40 is installed in the lower frame 30 of the "DL + DR" section.

Next, the parallel installation of the escape prevention device will be described.

Since the basic installation of the escape guard is to be installed only in the LL section and the LR section, it does not matter whether the shape of the escape guard is inverted “T”, “ㅁ” or inverted “c”. However, in the "DL + DR" section, the departure prevention tool having a "ㅁ" or reverse "c" shape wraps around the lower frame 30 and thus cannot be installed in the DL and DR sections. This is because the support bracket 40 is installed in the "DL + DR" section.

In the "DL + DR" section, it is possible to install the reverse T-shaped escape stopper (52). This is because the horizontal protrusion of the inverted “T” shape can be adjusted.

The vertical portion 522 of the release prevention port is firmly fixed to the side of the elevator door 10 by a fastening bolt. Needless to say, the guide shoe 12 is also firmly fixed to the lower end of the elevator door 10 by a fastening bolt.
