There is an advantage in that the phenomenon that the hoisting motor 210 is conducted can be prevented at the source by canceling the lateral load applied to the 210.

Here, the unloading load support portion 121 of the fall prevention beam 120 is at least twice the length (D) of the distance from the motor installation portion 122 to the end of the rotary shaft 220 of the hoisting motor 210. It is formed so that one end is connected to both ends of the motor installation portion 122 to provide a sufficient length to stably support the unloading load applied to the hoisting motor 210.

The vibration absorption horizontal maintaining unit 130 is interposed between the anti-conduction beam 120 and the fixed beam 110 so that the anti-conduction beam 120 is always horizontal even when an unloading load is applied to the hoisting motor 210. The anti-conduction beam 120 is connected to the fixed beam 110 to maintain and at the same time absorbs vibration and noise generated from the hoisting motor 210 and transmitted to the anti-conduction beam 120 to fix the fixed beam 110. Do not forward to.

For example, the vibration absorbing horizontal holding unit 130 may include a vibration absorbing means 131 and a horizontal adjusting means 132.

The vibration absorbing means 131 elastically supports the horizontal adjusting means 132 by having an elastic force and is installed on the fixed beam 110 to be generated from the hoisting motor 210 and transferred to the fall prevention beam 120. Absorbs the vibrations and noises to be transmitted to the fixed beam (110).

The vibration absorbing means 131 may include a fixing plate 131a, an elastic member 131b, and a support plate 131c.

The fixing plate 131a may be fixedly installed on the upper portion of the fixing beam 110 by welding or the like. The fixing plate 131a may be inserted into a lower end of the elastic member 131b at the center of the upper surface of the fixing plate 131a. The flow preventing protrusion 1310a may be formed to protrude.

The first through hole H1 penetrated by the adjusting means 132 may be provided.

The horizontal adjusting means 132 is installed on the anti-conduction beam 120 so as to be elastically supported by the vibration absorbing means 131 so that the vibration absorbing means 131 even if an uneven load is continuously applied to the hoisting motor 210. The position is restored to its original position by the elastic force of) so that the fall prevention beam 120 can always be horizontal, and at the same time, the horizontal adjusting member 132c is rotated to adjust the level of the fall prevention beam 120. .

For example, the horizontal adjusting means 132 may include a support frame 132a, a third through hole H3, a nut part 132b for coupling a horizontal adjusting member, and a horizontal adjusting member 132c.

The support frame 132a is interposed between the anti-conduction beam 120 and the fixed beam 110 so that the vibration absorbing means 131 is accommodated therein to support the anti-conduction beam 120 and is horizontal to an upper surface. The second through hole H2 penetrated by the adjusting member 132c may be provided.

The third through hole H3 may be provided in the fall prevention beam 120 to be penetrated by the horizontal adjusting member 132c.

Here, the support frame 132a is preferably fixed to the lower surface of the fall prevention beam 120.

The horizontal adjusting member coupling nut part 132b may be fixedly installed on the top surface of the anti-conduction beam 120 by welding or the like so as to communicate with the third through hole H3.

The horizontal adjustment member 132c has a lower end in ball contact with the ball contact groove 1311c of the support plate 131c of the vibration absorbing means 131, and an upper end thereof in the elastic member protection cap 131d, the support frame 132a, and In addition, the horizontal adjusting member coupling nut part 132b passes through the first through third through holes H1, H2, and H3 provided in the anti-conduction beam 120, and protrudes upward from the anti-conduction beam 120.

Again, with reference to Figures 1 to 3 will be described the operation and effect of the fall prevention device for an elevator hoist according to an embodiment of the present invention.

1 to 3, the fall prevention device 100 for an elevator hoist according to an embodiment of the present invention is one side of the one-sided load supporting portion 121 is installed so that a pair is spaced apart a predetermined interval on the fixed beam 110 Both ends of the motor installation unit 122 are connected to the end portion of the single load support unit 121 and the 'c' shape so that the hoisting motor 210 is installed on the motor installation unit 122 so that the hoisting machine Although the unloading load is applied to the motor 210, the hoisting motor, which is extended in the other direction of the motor installation unit 122 and is subjected to the unloading load by a pair of unloading load supporting units 121 installed on the fixed beam 110, is provided. By supporting the 210, the load applied to the hoisting motor 210 is canceled to prevent the phenomenon in which the hoisting motor 210 is conducted.

Therefore, in the elevator hoisting prevention device 100 according to an embodiment of the present invention, after connecting the plurality of wires to the hoisting motor 210 to prevent the hoisting motor 210 from being conducted, the hoisting machine By not having to perform a separate work of fixing the anchor wall to an elevator wall located on the opposite side of the rotating shaft 220 of the motor 210, the manufacturing cost and installation work of the elevator can be greatly reduced, and stability is also achieved. Make a big improvement.

In addition, the fall prevention device for elevator hoisting device 100 according to an embodiment of the present invention allows the hoisting motor 210 to be installed horizontally very easily even when the surface of the elevator hoisting motor 210 is difficult to install horizontally.

In more detail, even if the surface of the hoistway wall is uneven, even if the fixed beam 110 is not installed horizontally to the ground on the hoistway wall, the elevator hoisting prevention device 100 according to an embodiment of the present invention A tool such as a spanner is coupled to the tool engaging portion 1322c of the horizontal adjusting member 132c to rotate the bolt 1320c of the horizontal adjusting member 132c to be fixed to the fall prevention beam 120 to be fixed to the bolt portion ( 1320c) by raising and lowering the horizontal adjusting member coupling nut part 132b screwed to adjust the level of the fall prevention beam 120 so that the hoisting motor 210 can be leveled with the ground and installed very easily and quickly. do.

For example, in the case of a conventional general elevator, when the surface of the hoistway wall is uneven to prevent the fixed beam 110 from being installed horizontally with the ground, the hoisting motor 210 to which the unloading load is applied cannot be installed horizontally with the ground. As a result, a safety accident in which the hoisting motor 210 is conducted is very high due to the characteristics of the hoisting motor 210 to which a continuous unloading load is applied.

Therefore, in order to prevent the fall accident of the hoisting motor 210 in advance, the hoisting motor 210 must be installed horizontally with the ground when installing an elevator. Since it is virtually impossible for the worker to lift and level the hoisting motor 210, in order to level the hoisting motor 210, a separate hoisting hoisting motor 210 can be lifted on a narrow hoistway. Installation time of the hoisting motor 210 is increased by lifting the hoisting motor 210 by inserting a mechanism, and then repeating the leveling operation by inserting a separate horizontal adjustment plate between the hoisting motor 210 and the motor installation beam several times. This takes a very long time and a plurality of personnel must be put in, as well as safety accidents when the hoisting motor 210 There is risk involved with this issue.

On the contrary, the fall prevention device 100 for elevator hoists according to an embodiment of the present invention connects the fall prevention beam 120 by using a plurality of vibration absorbing horizontal holding units 130 on the fixed beam 110. Thereafter, without lifting the hoisting motor 210, a single worker simply rotates the bolt 1320 of the vibration absorption horizontal holding unit 130 using only a simple tool such as a spanner or the like. The horizontal adjustment member coupling nut portion 132b fixedly installed at the bottom) to raise and lower the anti-conduction beam 120 together with the horizontal adjustment member coupling nut portion 132b to level the anti-conduction beam 120. There is an advantage that the horizontal of the hoisting motor 210 can be adjusted very quickly and easily.

In addition, the fall prevention device 100 for an elevator hoist according to an embodiment of the present invention, the hoisting motor 210 is operated to elevate the elevator car, and noise and vibration are generated from the hoisting motor 210 to prevent the fall prevention beam ( Even if it is transmitted to 120, the noise and vibration transmitted to the fall prevention beam 120 is absorbed by the vibration absorbing means 131 of the vibration absorbing horizontal maintenance unit 130 is blocked by the lifting wall 110 through the fixed beam 110 This prevents it from being delivered to.

Therefore, the hoisting prevention device 100 for a hoist according to an embodiment of the present invention, even if the elevator is operated, the noise and vibration generated by the hoisting motor 210 is operated along the hoistway wall, such as living quarters or offices of the building. By not transmitting, it is possible to fundamentally prevent damage caused by noise and vibration generated by the operation of an elevator, which is a person living in a residential area of a building or working in an office.

In addition, the hoisting prevention device 100 for a hoist according to an embodiment of the present invention can be installed very quickly and easily on the hoisting motor 210 that is already installed without changing the structure.

Accordingly, the hoisting motor 210 conducts only a short construction period and a very low cost to the installed elevator that appeals to damage caused by noise and vibration when the elevator operates while the danger of the hoisting of the hoisting motor 210 exists. It also prevents noise and vibration from entering the building's living area, office, and elevator car, and prevents people living in the building's living area or working from the office from being damaged by the noise and vibration. Can be.

Meanwhile, in the case of a conventional general elevator in which a vibration-resistant rubber is installed between the hoisting motor 210 and the motor installation beam by intensively applying the greatest unloading load to the hoisting motor 210 during the initial operation of the hoisting car. When a very large load is applied to the anti-vibration rubber installed on the sheave 210 side to which the intensive load is concentrated, and the elevator is used for a predetermined time, the anti-vibration rubber installed on the sheave side is damaged so that the hoisting motor 210 is not leveled. Rather, a phenomenon in which concentrated stress is generated in the fixing member for fixing the hoisting motor 210 to the motor installation beam and the fixing member is broken causes the phenomenon that the hoisting motor 210 is conducted.

However, in the elevator hoisting prevention device 100 according to an embodiment of the present invention, when an initial load is intensively applied to the hoisting motor 210 at the time of initial operation, the horizontal adjusting member 132c is provided. While pressing the support plate 131c that is elastically supported by the elastic member 131b, a predetermined angle is rotated in the direction in which the unloading load is applied, thereby absorbing the impact applied by the concentrated unloading load that is instantaneously applied. 132c) can be prevented from being damaged by intensive load.

Here, the horizontal adjustment member 132c is rotated by a predetermined angle in the direction in which the ball contact portion 1321c is subjected to an uneven load along the ball contact groove 1311c of the support plate 131c, thereby preventing the horizontal adjustment member 132c. It is possible to minimize the wear phenomenon of the ball contact portion (1321c).

In addition, when the horizontal adjustment member 132c is rotated by a predetermined angle in the direction to which the unloading load is applied, the hoisting motor 210, the fall prevention frame 120, and the support frame 132a are also the horizontal adjustment member 132c. And a predetermined angle is rotated in the direction in which the load is applied, and in the case of the support frame 132a, when the predetermined angle is rotated in the direction in which the load is applied, one side portion is supported by the elastic member protection cap 131d. The hoisting motor 210, the fall prevention frame 120, the support frame 132a, and the horizontal adjustment member 132c are no longer rotated in the direction in which the unloading load is applied.

On the other hand, when the concentrated unloading load applied instantaneously during the initial operation of the hoisting motor 210 is removed, the elastic member 131b is restored to its original state by the original restoring force, and the horizontal adjustment is performed as the elastic member 131b is restored to the original state. The member 132c is also pushed up by the support plate 131c that is elastically supported by the elastic member 131b, and the hoisting motor 210, the fall prevention frame 120, and the support frame in the opposite direction to which the unloading load is applied.

By doing so, the hoisting motor 210 by the unloading load can be operated more stably without the occurrence of a safety accident that is conducted.

As described above, the fall prevention device 100 for an elevator hoist according to an embodiment of the present invention prevents the fall of the motor installation part 122 connected to a pair of unloading load support parts 121 in a 'c' shape. The hoisting machine motor 210 to which the unloading load is applied by the beam 120 is supported to cancel the unloading load applied to the hoisting motor 210 to prevent the hoisting motor 210 from conducting.

In addition, the fall prevention device 100 for an elevator hoist according to an embodiment of the present invention, even during the initial operation of the hoisting motor 210, the vibration absorbing horizontal maintaining unit even up to an intensive load applied to the hoisting motor 210 instantaneously ( 130 to prevent the horizontal adjustment member 132c from being damaged, and to remove the intensive unloading force applied to the hoisting motor 210 at a moment, to restore the original force of the vibration absorption horizontal maintenance unit 130. By restoring the hoisting motor 210 so that the hoisting motor 210 is quickly restored to its original level, the hoisting motor 210 can be inherently prevented from running and the elevator can be safely operated without safety accidents. There is an advantage to doing this.

In addition, the fall prevention device for elevator hoisting apparatus 100 according to an embodiment of the present invention is a bolt portion of the vibration absorbing horizontal holding unit 130 by using only one simple tool without lifting the hoisting motor 210. By only rotating the operation 1320c, the level of the fall prevention beam 120 can be adjusted to quickly and easily adjust the horizontality of the hoisting motor 210, thereby greatly reducing the installation time and the labor of the elevator. There is this.

In addition, the fall prevention device 100 for an elevator hoist according to an embodiment of the present invention is transmitted to the fall prevention beam 120 even if the hoisting motor 210 is operated so that noise and vibration are transmitted to the fall prevention beam 120. The noises and vibrations are absorbed and blocked by the vibration absorbing means 131 of the vibration absorbing horizontal holding unit 130 to prevent the noises and vibrations from being transmitted to the wall of the hoistway through the fixed beam 110. There is an advantage that the people who live in the residential area of the building or the office, etc. are not transmitted and thus can be fundamentally prevented from being damaged by the noise and vibration generated when the elevator is operated.

In addition, the hoisting prevention device for hoisting apparatus 100 according to an embodiment of the present invention can be installed very quickly and easily without changing the structure even in an elevator which is already installed, and thus there is a danger of conduction of the hoisting motor 210. At the same time, a short construction period and a very low cost are applied to an already installed elevator that complains of damage caused by noise and vibration during operation of the elevator, thereby preventing the hoisting motor 210 from conducting, and also in a building's living area or office and By blocking the noise and vibration flowing into the elevator car, there is an advantage that can prevent people living in the building's living area or working in the office to be damaged by the noise and vibration.
